Description

{System and method for automatically checking prescription medicine and checking method of the same}

The present invention relates to an automatic pharmaceutical inspection system and inspection method.

In general, pharmaceuticals prepared in hospitals or pharmacies are provided to patients in the form of individually packaged pharmaceuticals that are packaged as a single dose by a pharmaceutical automatic packaging machine after a pharmacist prepares at least one medicine according to a doctor's prescription.

However, when a pharmaceutical is packaged by an automatic drug packaging machine, there is a problem in that it is not easy to check whether the medicine is made according to a doctor's prescription. In order to solve this problem, the packaging of the pharmaceutical preparation is made of a transparent material so that the medicines inside the individually packaged pharmaceuticals can be easily identified from the outside.

On the other hand, there is a problem in that it takes a lot of manpower and inspection time to check whether individually packaged pharmaceuticals are made with medicines according to a doctor's prescription in hospitals or pharmacies that manage pharmaceuticals in large quantities.

Furthermore, there is a problem in that a person cannot easily identify drugs having the same color or size or similar with the naked eye, so that when a defect occurs in individually packaged pharmaceuticals, a patient suffers fatal damage.

In order to solve the above problems, an automatic pharmaceutical inspection system for automatically inspecting pharmaceuticals as disclosed in Korean Patent Application Laid-Open No. 10-2011-0077759 has been developed.

The automatic pharmaceutical examination system disclosed in Korean Patent Application Laid-Open No. 10-2011-0077759 includes a pharmaceutical information server that manages pharmaceutical information on pharmaceuticals and an identification code assigned to individually packaged pharmaceuticals, and an inspection unit connected to the pharmaceutical information server. do.

In detail, the inspection unit captures the individually packaged pharmaceuticals, and analyzes the captured images of the individually packaged pharmaceuticals to extract drug information of the individually packaged pharmaceuticals. And, the inspection unit is configured to determine whether there is a defect in the individually packaged drug by checking whether the extracted drug information and the drug information of the drug managed in the dispensing information server match each other.

However, the automatic pharmaceutical inspection system disclosed in Korean Patent Application Laid-Open No. 10-2011-0077759 determines the presence or absence of defects in individually packaged pharmaceuticals using an image of individually packaged pharmaceuticals. Therefore, there is a problem that the shape of the individually packaged pharmaceuticals varies depending on the arrangement or placement of the pharmaceuticals constituting the individually packaged pharmaceuticals, and errors may occur in the defect inspection of individually packaged pharmaceuticals.

For example, when two or more drugs are transferred to the image processing unit in an overlapping state, the type and number of individual drugs may not be accurately identified.

Referring to FIG. 1 , an automatic pharmaceutical preparation inspection system 10 according to an embodiment of the present invention may include a preparation information server 200 and a preparation inspection apparatus 100 .

The dispensing information server 200 stores and manages the drug information of the drug and the identification code assigned to the individually packaged drug. Here, the drug information of the drug may include the patient, the person in charge, the date and time of drug prescription, the time taken, the quantity of individually packaged drugs, the shape, weight, color, symbol, and the histogram of the distance between the center and the outline of the drug constituting the individually packaged drug. can In addition, the identification code is a means for easily inquiring drug information of a pharmaceutical corresponding to an individually packaged pharmaceutical, and may be at least one of a barcode, an RFID tag, a number, a character, and a QR code.

Herein, the individually packaged pharmaceuticals refer to tablets of a single dose, and the tablets may be understood to include tablets in solid form and medicine in capsule form.

The dispensing information server 200 searches for individually packaged pharmaceuticals to be inspected based on the information planted in the identification code when the pharmaceutical examination device 100 transmits the identification code, and the pharmaceuticals of the pharmaceuticals corresponding to the retrieved individually packaged pharmaceuticals. The information is retrieved and transmitted to the pharmaceutical testing device 100 .

The pharmaceutical testing apparatus 100 recognizes the identification code of individually packaged pharmaceuticals to be inspected and transmits them to the dispensing information server 200, and from the dispensing information server 200 to the individually packaged pharmaceuticals to be inspected Receive drug information.

And the pharmaceutical test apparatus 100 extracts an image frame of the individually packaged pharmaceutical to be tested by photographing the individually packaged pharmaceutical to be inspected. In addition, the drug test apparatus 100 extracts drug information of a drug to be tested from the extracted image frame, and determines whether the extracted drug information matches the drug information received from the dispense information server 200 . And, it is determined whether there is a defect in the individually packaged drug product to be inspected according to whether the drug information is the same.

On the other hand, since the pharmaceutical inspection apparatus 100 takes pictures of individually packaged pharmaceuticals and determines the presence or absence of defects before determining the presence or absence of defects, when the tablets in individually packaged pharmaceuticals overlap, the accuracy in determining the presence or absence of defects decreases, so the overlapping state of tablets in individually packaged pharmaceuticals is released will do

To this end, the pharmaceutical test apparatus 100 includes a control unit 110 , a moving unit 120 , an identification code recognition unit 130 , a drug flattening unit 140 , a separation distance measuring unit 145 , an image processing unit 150 , It may include a pharmaceutical analysis unit 160 , a pharmaceutical defect confirmation unit 170 , a pharmaceutical defect warning unit 180 , and a storage unit 190 .

The identification code recognition unit 130 recognizes the identification code displayed on the individually packaged pharmaceutical product to be inspected and transmits it to the control unit 110 . Therefore, the control unit 110 transmits the identification code transmitted by the identification code recognition unit 130 to the dispensing information server 200, and provides drug information corresponding to the individually packaged pharmaceutical product to be inspected from the dispensing information server 200. can receive

The drug flattening unit 140 releases the overlapping state of a plurality of drugs (tablets) included in individually packaged pharmaceuticals to be inspected, which will be described later with reference to FIGS. 4 to 6 .

The image processing unit 150 captures and analyzes images of individually packaged pharmaceuticals to be tested, and transmits them to the control unit 110 .

The pharmaceutical analysis unit 160 compares and analyzes the pharmaceutical information of the pharmaceutical received from the dispensing information server 200 and the pharmaceutical information of the individually packaged pharmaceutical that is photographed by the image processing unit 150 and transmitted to the control unit 110 to be tested. to determine whether they match. The drug information comparatively analyzed by the pharmaceutical analysis unit 160 includes histogram information based on images of a plurality of drugs constituting individually packaged drugs. In addition, the pharmaceutical preparation analysis unit 160 determines whether or not the individually packaged pharmaceutical product to be inspected is defective according to the result of determining whether the drug information matches.

If the pharmaceutical analysis unit 160 determines that it is a defect in the individually packaged pharmaceutical to be inspected, the pharmaceutical defect warning unit 180 warns of a defect in the individually packaged pharmaceutical to be inspected.

For example, a normal label or an abnormal label is created depending on the presence or absence of defects in the individually packaged pharmaceutical product to be inspected and attached to the individually packaged pharmaceutical product to be inspected. Accordingly, the user can easily identify the presence or absence of defects in individually packaged pharmaceuticals with the naked eye.

Here, the pharmaceutical defect warning unit 180 is a means for outputting a warning sound according to the presence or absence of defects in the individually packaged pharmaceutical to be inspected so that the user can audibly recognize the presence or absence of a defect in the individually packaged pharmaceutical to be inspected. can be implemented. In addition, the pharmaceutical product defect warning unit 180 is a means for outputting a warning display according to the presence or absence of defects in the individually packaged pharmaceutical product to be inspected so that the user can visually recognize the presence or absence of a defect in the individually packaged pharmaceutical product to be inspected. can be implemented.

The storage unit 190 is implemented as a general storage device, and stores a program and processed data consisting of operation and control commands of the pharmaceutical testing apparatus 100 .

Referring to FIG. 2 , the image processing unit 150 may include a lighting unit 151 , a photographing unit 152 , an image acquiring unit 153 , and an image analyzing unit 154 .

The lighting unit 151 may be implemented with general lighting such as an LED lamp. This lighting unit 151 is disposed on the lower side of the moving unit 120, and by providing lighting toward the photographing unit 152 according to the photographing mode, the photographing unit 152 can clearly photograph the individually packaged pharmaceuticals to be inspected. let there be

The photographing unit 152 may be implemented as a general camera such as a charge-coupled device (CCD) camera. The photographing unit 152 photographs the individually packaged pharmaceutical preparations to be inspected in black and white or color, and transmits the photographed image information to the image acquisition unit 153 . The photographing unit 152 may photograph the upper surface of the individually packaged pharmaceutical preparation to be inspected.

The image acquisition unit 153 extracts image frames of individually packaged pharmaceuticals at set time intervals from the image information transmitted from the photographing unit 152 and transmits them to the image analysis unit 154 .

The image analysis unit 154 extracts drug information of a pharmaceutical to be tested from the image frame transmitted by the image acquisition unit 153 and transmits it to the control unit 110 . At this time, the drug information of the individually packaged pharmaceutical preparations to be tested to be extracted by the image analysis unit 154 may include the type, quantity, weight, shape, color and size of medicines constituting the individually packaged pharmaceuticals to be tested. have.

On the other hand, as the image analysis method of the image analysis unit 154, a conventionally known analysis method may be used and is not limited to a specific analysis method, for example, individually packaged pharmaceuticals to be tested as disclosed in the prior art document. The drug information of the drug product may be a histogram of the distance between the center and the outline of the drug in individually packaged pharmaceuticals.

To this end, the image analysis unit 154 extracts the binarized image of the individually packaged pharmaceutical to be tested by image binarization of the image frame of the individually packaged pharmaceutical to be tested using the threshold value. Then, the center and the outline of the binarized image are extracted. Then, the distance (L) between the center and the outline of the binarized image is extracted, and a histogram of the distance between the center and the outline for each drug to be tested is extracted and transmitted to the controller.

3 is a block diagram illustrating an individually packaged pharmaceutical analysis unit of the automatic pharmaceutical examination system according to an embodiment of the present invention. Referring to FIG. 3 , the pharmaceutical preparation analysis unit 160 may include a pharmaceutical preparation information input unit 161 , a pharmaceutical preparation information storage unit 162 , and a first individually packaged pharmaceutical product defect determination unit 163 .

The pharmaceutical preparation information input unit 161 receives the pharmaceutical information of the pharmaceutical to which the individually packaged pharmaceutical product to be tested is transmitted from the dispensing information server 200 . For example, a histogram of the distance between the center and the outline of each drug constituting individually packaged pharmaceuticals may be input.

In addition, the pharmaceutical preparation information input unit 161 receives the medicine information of the individually packaged pharmaceutical product to be tested, which is transmitted from the image processing unit 150 to the control unit 110 . For example, a histogram of the distance between the center and the outline of the individually packaged pharmaceutical product to be inspected may be input.

The pharmaceutical preparation information storage unit 162 stores the pharmaceutical information of the pharmaceutical received from the dispensing information server 200 and the pharmaceutical information of the pharmaceutical transmitted from the image processing unit 150 to the controller 110 . For example, the distance histogram information between the center and the outline of the drug corresponding to the individually packaged drug to be tested, and the center and the outline of the drug of the individually packaged drug to be tested actually extracted while passing through the image processing unit 150 You can save a histogram of the distance between .

The drug product defect determination unit 163 is configured to check whether the drug information of the drug stored in the drug drug information storage unit 162 matches the drug information of the drug transmitted from the image processing unit 150 to the control unit 110 , It is judged whether there is a defect in the individually packaged pharmaceutical product. For example, the distance histogram between the center and the outline of the drug corresponding to the individually packaged pharmaceutical to be inspected, and the center and the outline of the drug of the individually packaged pharmaceutical to be tested actually measured while passing through the image processing unit 150 Depending on whether the distance between the histograms match or not, it is possible to determine whether the individually packaged pharmaceutical product to be inspected is defective.

On the other hand, although not shown, the drug defect determination unit 163 may further include a weight sensing unit, which detects the weight of individually packaged pharmaceuticals and transmits it to the pharmaceutical defect determination unit 163, and the pharmaceutical defect determination unit ( 163) compares the weight of the individually packaged pharmaceutical input from the weight detection unit and the weight information stored in the pharmaceutical information storage unit 162, and adds the presence or absence of defects in the individually packaged pharmaceutical to be inspected according to whether the weights match or not is determined and transmitted to the control unit 110 .

4 is a view schematically showing the main configuration of an automatic pharmaceutical drug inspection system according to an embodiment of the present invention, and FIGS. 6 and 7 are views showing a state in which the drug is flattened by the drug flattening unit.

Referring to FIG. 4 , the moving unit 120 may include a conveyor belt 121 and a driving unit (not shown) for moving the conveyor belt 121 . The moving unit 120 having such a configuration includes the individually packaged pharmaceuticals P to be inspected, the identification code recognition unit 130 , the medicine flattening unit 140 , the image processing unit 150 , and the pharmaceutical defect warning unit 180 ). to move through successively.

Accordingly, the identification code recognition process by the identification code recognition unit 130, the pharmaceutical preparation flattening process by the drug flattening unit 140, the image processing process by the image processing unit 150, and the individually packaged pharmaceutical product defect warning unit 180 The label generation process may be performed continuously. And, since the above processes are continuously performed while the preparation moves along the moving part, the preparation test time can be shortened.

The drug flattening unit 140 is installed on the moving path of the conveyor belt 121 of the moving unit 120, and the overlapping state by contact with the tablets in the individually packaged pharmaceuticals passing through the identification code recognition unit 130 Release to flatten the drug. The drug flattening unit 140 has the conveyor belt 121 interposed therebetween, that is, the first member 142 and the second member 144 are installed on the lower side and the upper side of the conveyor belt 121 to be spaced apart from each other. ) may be included.

Specifically, according to an embodiment of the present invention as shown in FIG. 5 , the first member 142 is a roller member installed to contact the lower surface of the conveyor belt 121 , and the second member 144 is the conveyor belt 121 . ) may be a plate member installed at a certain distance away from the upper surface. The plate member may have a polygonal cross-section such as a quadrangle. Since the overlapping state is released by contact with the tablets, it is preferable that the first member 142 and the second member 144, particularly the second member 144, be made of a soft material so as not to break the tablet. do.

Meanwhile, according to another embodiment of the present invention as shown in FIG. 6 , a roller member may be applied to the second member 144 . In this case, the rotation directions of the first member 142 and the second member 144 are mutually exclusive. can be the opposite.

The first member 142 is installed to be perpendicular to the traveling direction of the conveyor belt 121 , that is, the virtual connection line between the central axes of the first member 142 and the second member 144 is the conveyor belt 121 and the become orthogonal. When a roller member is applied to the second member 144 , the central axes of the first member 142 and the second member 144 may be parallel to each other.

The first member 142 is disposed to be in contact with the lower surface of the conveyor belt 121 , and the conveyor belt 121 horizontally moves in a state in contact with the first member 142 in this way so that the conveyor belt 121 sags. can prevent In addition, when the individually packaged pharmaceuticals moving while being placed on the conveyor belt 121 pass through the pharmaceutical flattening unit 140, the tablets p1 and p2 are overlapped with the individually packaged pharmaceuticals so that they come into contact with the second member 144 In this case, the conveyor belt 121 can be pressed, and since the first member 142 supports the conveyor belt 121, sagging of the conveyor belt 121 can be prevented, so that only the set pharmaceutical agent can pass. do.

The second member 144 is installed to be upwardly spaced apart from the upper surface of the conveyor belt 121 , and a distance upwardly spaced from the conveyor belt 121 is set and controlled by the controller 110 .

For example, the information on individually packaged pharmaceuticals to be inspected transmitted from the preparation information server 200 to the control unit 110 may include thickness information of individual tablets constituting the preparation, and the thickness information of the individual tablets. Correspondingly, the control unit 110 may adjust the separation distance between the first member 142 and the second member 1440. The first member 142 is installed to be in contact with the lower surface of the conveyor belt 121, so that the position is fixed. Preferably, the second member 144 is moved so that the separation distance can be adjusted.

The separation distance between the first member 142 and the second member 144 may be a value corresponding to the thickness of the conveyor belt 121 plus the thickness of a standard tablet among tablets in the individually packaged pharmaceutical preparation. Here, the corresponding value means a value obtained by adding a predetermined error value to the thickness of the reference tablet. Also, the reference tablet may be the thickest tablet among the tablets in the pharmaceutical preparation. Accordingly, the separation distance between the first member 142 and the second member 144 may be a value obtained by adding a predetermined error value to the thickness of the reference tablet and the thickness of the conveyor belt.

Usually, the thickest tablet among tablets in individually packaged pharmaceuticals is usually smaller than the sum of the thicknesses of any two tablets excluding these tablets, so the reference tablet may be set as the thickest tablet.

However, the sum of the thicknesses of any two tablets may be smaller than the thickness of the thickest tablet, and in this case, the two tablets may pass through the drug flattening unit 140 even in an overlapping state. Accordingly, in this case, the reference tablet may be two. In this case, the first reference tablet may be the sum of the thicknesses of the two tablets, and the second reference tablet may be a value corresponding to the thickness of the thickest tablet. Therefore, the control unit 110 adjusts the separation distance between the first member 142 and the second member 144 to a value corresponding to the sum of the thicknesses of the first reference tablet at first, and after a set period of time (this The set value may be appropriately adjusted according to the speed of the conveyor belt) It may be adjusted to a value corresponding to the thickness of the second reference tablet.

Since the first member 142 rotates while in contact with the conveyor belt 121 , it can rotate in a direction that goes forward in the moving direction a1 of the conveyor belt 121 , that is, counterclockwise in the drawing. . The first member 142 may be an idle roller that does not require a separate driving force and may rotate by friction with the conveyor belt 121 , or may rotate by a separate driving force.

When the plate member is applied to the second member 144 as shown in FIG. 5 , the second member 144 blocks the tablet p1 of the upper end among the overlapping tablets and prevents them from passing through, so that the overlapping state of the tablets is released. do. That is, the tablets of the pharmaceutical preparation move in the moving direction a1 of the conveyor belt 121 by the conveyor belt 121. When the tablets overlap, the upper tablet p1 is blocked by the second member 142. It cannot move any more, and when the tablet p2 at the lower end passes through the second member 142 , the tablet p1 at the upper end falls to the conveyor belt 121 by its own weight and then passes through the second member 142 . will do

On the other hand, when the roller member is applied to the second member 144 as shown in FIG. 6 , the second member 144 blocks the upper tablet p1 among the overlapping tablets and at the same time the moving direction of the conveyor belt 121 ( By pushing in the direction a2 opposite to a1), the overlapping state of the tablets p1 and p2 is released.

The separation distance measuring unit 145 measures the distance from the second member 144 to the conveyor belt 121 and transmits it to the control unit 110 . The separation distance measuring unit 145 may be a distance measuring sensor to which a conventional laser or ultrasonic sensor is applied. The control unit 110 uses the information received from the separation distance measuring unit 145 to confirm whether the adjusted separation distance between the first member 142 and the second member 144 is correct.

That is, as described above, the controller 1100 adjusts the separation distance between the first member 142 and the second member 144 based on the thickness information of the tablets, but an error may occur in the adjusted separation distance. Accordingly, the control unit 110 uses the distance information between the second member 144 and the conveyor belt 121 received from the separation distance measurement unit 145, the first member 142 and the second member 144 Check whether the adjusted separation distance is correct, and if it does not fit within the error range, it is adjusted again.

The separation distance measuring unit 145 is preferably installed on the second member 144 because accurate distance measurement is possible only when it moves with the movement of the second member 144 . For example, when the second member 144 is a plate member, a distance sensor may be installed on the extension member extending from the upper end of the plate member as shown in FIG. 5 . Meanwhile, when the second member 144 is a roller member, a distance sensor may be installed in an extension member extending from the shaft member to which the roller rotation shaft is fixed.

Hereinafter, with reference to FIG. 7, an inspection method of the automatic pharmaceutical inspection system according to an embodiment of the present invention will be described with reference to the drawings.

First, when the individually packaged pharmaceutical to be inspected enters the pharmaceutical inspection apparatus 100, the identification code recognition unit 130 recognizes the identification code of the individually packaged pharmaceutical to be inspected and transmits it to the control unit 110 (S10) ). At this time, the lighting unit 151 is controlled to prevent diffuse reflection due to non-uniformity of the wrapping paper of individually packaged pharmaceuticals to be inspected, and the identification code recognition unit 130 accurately and easily identifies the identification codes of individually packaged pharmaceuticals to be inspected. can make you aware

Then, the control unit 110 transmits the identification code of the individually packaged pharmaceutical product to be inspected transmitted by the identification code recognition unit 130 to the preparation information server 200, and from the preparation information server 200 to the individual inspection object The packaged drug receives the drug information of the corresponding drug (S20). Here, the drug information of the drug product corresponding to the individually packaged drug product to be inspected may include the type, quantity, size, shape, color, etc. of the drug, and may also include thickness information. In addition, the distance histogram information between the center and the outline of the drug constituting the individually packaged pharmaceutical preparation to be inspected may be further included.

Then, as the conveyor belt 121 constituting the moving unit 120 moves, the individually packaged pharmaceutical preparations to be inspected pass through the drug flattening unit 140 while a plurality of drugs overlap each other. to be released (S30). As described above, the control unit 110 includes the first member 142 and the second member constituting the medicine flattening unit 140 by using the thickness information of the medicine among the information transmitted from the dispensing information server 200 . The separation distance of the member 144 may be adjusted. In addition, the control unit 110 may check the adjusted separation distance by using the distance information between the second member 144 and the conveyor belt 121 received from the separation distance measurement unit 145 and adjust it again.

The individually packaged pharmaceutical preparations, which have passed through the pharmaceutical planarization unit 140 , are transferred to the image processing unit 150 . Then, the image processing unit 150 extracts an image frame of the individually packaged pharmaceutical to be tested by photographing the individually packaged pharmaceutical to be tested, and drug information of the individually packaged pharmaceutical to be tested from the extracted image frame Extract (S40).

Next, the pharmaceutical analysis unit 160 transmits the pharmaceutical information corresponding to the individually packaged pharmaceutical to be inspected transmitted by the dispensing information server 200 and the individual packaged pharmaceutical to be inspected extracted by the image processing unit 150 . It is determined whether the drug information matches, and it is determined whether there is a defect in the individually packaged pharmaceutical product to be inspected according to the determination result (S50).

That is, when it is determined that the drug information corresponding to the individually packaged pharmaceutical to be tested transmitted by the dispensing information server 200 matches the actual drug information of the individually packaged pharmaceutical to be tested extracted by the image processing unit 150 , the pharmaceutical defect warning unit 180 attaches a normal label to the individually packaged pharmaceutical product to be inspected, and then ends the inspection. On the other hand, when it is determined that there is a discrepancy, the defect warning unit 180 of individually packaged pharmaceuticals warns of defects in individually packaged pharmaceuticals to be inspected. Here, the warning may be at least one of attaching an abnormal label to the individually packaged pharmaceutical product to be inspected, generating a warning sound, and outputting a warning mark.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can realize that the present invention may be embodied in other specific forms without changing its technical spirit or essential features. you will be able to understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
