Description

  The present invention relates to a stool collection container for collecting stool during a stool test.

  Conventionally, various types of stool collection containers have been proposed as a stool collection container for collecting stool during stool inspection (stool test), but many of them have a stool collection rod provided with a spiral groove at the tip. A lid and a container body in which a storage solution is stored are provided (for example, see Patent Document 1).

  In this type of stool collection container, when collecting the stool, the lid is removed, the stool is scraped into the spiral groove provided at the tip by piercing the stool, etc. The stool collected in the preservation solution contained in the container main body is suspended by returning the stick into the container and closing the lid. The stool collected in this way is subjected to the inspection by filtering the suspension, but the amount of stool suspended in the storage solution is too large for a good inspection. It is required to suspend a certain amount of stool in the preservation solution so that it is not too little.

For this reason, in many stool collection containers, when returning the stool collection stick to which the stool is attached into the container body, the stool collection stick is attached to the scraped portion formed by providing a partition inside the container body. The extra stool is removed by insertion so that a certain amount of stool can be collected.
For example, in the stool collection container described in Patent Document 1, a scraper for removing excess stool adhering to the stool collection rod is provided in the inner stopper, and the inner stopper is inserted into the container body by inserting the inner stopper into the container body. A scraped portion is formed inside the main body.

  However, since the stool collection container described in Patent Document 1 squeezes the container body and drops the suspended liquid in which the stool is suspended, the container body uses a flexible material. On the other hand, a lid having a stool collection rod is attached to the inner stopper, and a scraped part is formed to remove excess stool from the stool collection rod, so that it is molded using a hard material. . For this reason, since the container main body and the inner stopper are made of different materials that are difficult to weld, the inner stopper mounted in the container main body cannot be fixed, and when the lid having the stool collection rod is attached to and detached from the inner stopper, There is a concern that the container body and the inner stopper may be idle, or the lid body and the inner stopper may rotate together.

  The present invention has been made in view of the above circumstances, and a stool collection container in which a lid body having a stool collection rod and an inner plug in which the lid body is attached and detached and a frayed portion is formed are mounted in the container body. The purpose of the present invention is to provide a stool collection container that prevents the container body and the inner stopper from rotating freely when the lid is attached to and detached from the inner stopper, or the lid and the inner stopper are not rotated together.

A stool collection container according to the present invention includes a lid having a stool collection rod that seals the inside of the container, a cylindrical container body that is open on the base end side, and a frayed portion formed from the base end side of the container main body. An inner plug mounted in the container main body, forming a flange portion along an opening edge on the proximal end side of the container main body, and extending along a circumferential direction at a predetermined position on the outer peripheral surface of the inner plug. A protruding portion that overlaps with the flange portion, an engaging portion is formed on one of the flange portion or the protruding portion, and a locking portion that partially protrudes so as to fit the engaging portion on the other side. The container body and the inner stopper are prevented from rotating by forming and engaging the engaging part and the locking part .

  According to the present invention, a scraping portion for removing excess stool adhering to the stool collection rod is formed in the inner plug, the inner plug from which the lid body is attached and detached is provided, and the inner plug is attached to the container body. In a stool collection container in which a scraped portion is formed inside the container main body, it is possible to prevent the container main body and the inner plug from rotating freely when the lid is attached to and detached from the inner plug, or the cover and the inner plug from rotating together.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  A stool collection container 1 shown in FIGS. 1 and 2 is for collecting stool during a stool inspection, and includes a lid body 2 that seals the container, a cylindrical container body 3 that stores a storage solution, and a container body. The inside plug 4 is mounted inside, and the dripping cap 5 is mounted on the distal end side of the container body 3 by screwing. These members constituting the stool collection container 1 can be manufactured, for example, by injection molding using a thermoplastic resin such as polypropylene or polyethylene, but the container body 3 is low so that it can be squeezed. It is preferable to form a cylindrical shape or a cylindrical shape having an elliptical or oval cross section using a flexible material such as density polyethylene.

  As shown in FIG. 3, the lid body 2 has a stool collection rod 2b for collecting feces together with a lid portion 2a for sealing the inside of the container. A spiral groove 2c engraved in a spiral shape is formed on the distal end side of the stool collection rod 2b, and in order to collect feces with the stool collection rod 2b, the lid 2 is removed from the container, and the stool collection rod The stool is collected by piercing the stool with 2b and scraping it with the spiral groove 2c. After the stool is collected, the lid 2 is attached to the container again, the stool collection rod 2b is returned to the container, and the stool collected in the storage solution stored in the container body 3 is suspended.

  In the present embodiment, the spiral groove 2c is formed at the distal end side of the stool collection rod 2b. However, the present invention is not limited to this as long as feces can be collected reliably. For example, it is possible to provide a plurality of grooves that are orthogonal to the longitudinal direction and go around the distal end side of the stool collection rod 2b. In addition, one or more concave portions or through holes having various shapes may be provided. Since the stool has various properties such as solid stool, soft stool, and liquid stool, various stool collection devices have been devised for collecting these stool.

  In the stool collection container 1, the lid body 2 includes an annular convex portion 4g formed on the outer peripheral surface of the inner plug 4 along the circumferential direction, and an annular convex portion 2f formed on the inner peripheral surface of the lid portion 2a along the circumferential direction. The fitting means of the lid body 2 is not limited to this. If the inside of the container can be sealed, for example, although not particularly illustrated, by screwing with a screw provided on the inner peripheral surface of the lid portion and a screw provided on the outer peripheral surface of the inner plug 4, A lid may be attached.

In order to improve the sealing performance when the lid 2 is attached to the container, although not shown in particular, a protrusion that contacts the end edge of the inner plug 4 is formed in an annular shape on the inner surface of the lid 2a. Is also effective.
Further, in the stool collection container 1, the sealing portion is secured by bringing the lid portion 2 a into close contact with the inner peripheral surface of the inner stopper 4, but between the outer peripheral surface of the inner stopper 4 and the lid portion 2 a. A gap is formed. By forming a gap between the outer peripheral surface of the inner stopper 4 and the lid 2a, when the stool collection rod 2b from which the stool is collected is returned to the container, the stool is mistakenly attached to the edge of the inner stopper 4 In the case where the stool adheres to the stool, the stool can be allowed to flow into the gap so as not to protrude outside the stool collection container 1.

  Such a lid body 2 is preferably formed by integrally molding the lid portion 2a and the stool collection rod 2b by injection molding, but they may be molded separately. If the inside of a container can be sealed with the cover part 2a, and the stool collection rod 2b has the hardness which can be stabbed into feces, the specific structure of the cover body 2 will not be specifically limited.

  Moreover, in order to improve the visibility of the stool adhering to the stool collection rod 2b, it is preferable to color the stool collection rod 2b with a white or light color with high brightness. In particular, it is more preferable that the color is pale green, which is close to the complementary color of fecal color (brown to tan).

  Further, the container body 3 has a partition wall 3b in which an extraction hole 3a is formed on the distal end side, and the dripping cap 5 attached to the distal end side of the container body 3 by screwing (screw tightening) is applied. It has the sealing body 5a which seals the extraction hole 3a. Thereby, the stool collection container 1 of this embodiment is opened by loosening the screwing of the dropping cap 5 (see FIG. 2), and resealed by retightening the dropping cap 5.

  In this embodiment, the 1st cyclic | annular convex part 3d is formed in the predetermined | prescribed position along the circumferential direction in the outer peripheral surface at the front end side of the container main body 3 with which the dripping cap 5 is mounted | worn. At the same time, on the inner peripheral surface of the dropping cap 5, a second annular convex portion 5b is formed at a predetermined position along the circumferential direction.

  As shown in FIG. 2, the position where the first annular convex portion 3d is formed on the outer peripheral surface on the distal end side of the container body 3 and the position where the second annular convex portion 5b is formed on the inner peripheral surface of the dropping cap 5 are dropped. When the sealing body 5a is separated and the pouring hole 3a is opened by loosening the screwing of the cap 5, the first annular convex part 3d and the second annular convex part 5b are adjusted as appropriate. To do. By doing in this way, it can be sensed that the stool collection container 1 is in an opened state by the feeling that the first annular convex portion 3d and the second annular convex portion 5b are in contact with each other. It is possible to prevent the dropping cap 5 from falling off due to being loosened too much.

  Further, in the present embodiment, in order to screw the dropping cap 5, the main body side thread 3 e is formed on the outer peripheral surface on the distal end side of the container main body 3, and the cap side is formed on the inner peripheral surface of the dropping cap 5. A thread 5c is formed. When forming these threads, the main body side thread 3e of the container body 3 and the cap side thread 5c of the dropping cap 5 are in contact with the first annular protrusion 3d and the second annular protrusion 5b. It is preferable that the height of one or both of the main body side thread 3e and the cap side thread 5c is reduced or removed so that the two can get over each other.

Here, FIG. 4 shows an example of a configuration that enables the main body side thread 3e of the container body 3 and the cap side thread 5c of the dropping cap 5 to cross over each other.
4 (a) is obtained by reducing the height of the threaded range extending from screw threads 5c ₁ located on the second annular projection 5b of the cap side screw bar 5c of the drip cap 5 to 5c _2. FIG. 4B shows a screw thread in a range extending from the screw threads 3e ₁ to 3e ₂ located on the side away from the first annular convex portion 3d of the main body side screw thread 3e of the container body 3 (a part of the screw thread in the figure). (Represented by a chain line). FIG. 4 (c) shows that the thread within the range of the thread 3 e ₁ of the body-side thread 3 e of the container body 3 (part of which is indicated by a chain line in the drawing) is removed, and the cap-side thread 5 c of the dripping cap 5 is removed. The height of the thread in the range extending from 5c ₁ to 5c ₂ is reduced.

  Therefore, when the stool collection container 1 is opened and the first annular convex portion 3d and the second annular convex portion 5b are in contact with each other, the dropping cap 5 is idle with respect to the container main body 3. In this manner, since the inspection is performed without removing the drip cap 5 from the container main body 3 by rotating the drip cap 5 with respect to the container main body 3, contamination of the drip cap required for re-sealing is required. Loss is prevented.

  Furthermore, in this embodiment, as shown in FIG. 5, the tape-like member 7 in which the perforation 7 a is formed along the circumferential direction is located at the boundary between the container body 3 and the dropping cap 5. It is preferable to wrap around. By doing in this way, loosening of the dripping cap 5 before opening of the stool collection container 1 (before inspection) is prevented, and confirmation of the presence or absence of opening becomes easy.

  On the other hand, the base end side of the container main body 3 is opened so that the inner plug 4 can be mounted in the container main body 3, and when the inner plug 4 is mounted in the container main body 3, the inner peripheral surface of the container main body 3. And the outer peripheral surface of the inner plug 4 are in close contact with each other in a liquid-tight manner so that the storage solution stored in the container body 3 does not leak.

  As shown in FIGS. 6 and 7, the distal end portion of the inner plug 4 mounted in the container body 3 has a bottom surface 4a orthogonal to the longitudinal direction, and the stool collection apparatus that the lid body 2 has in the center of the bottom surface 4a. A scraping portion 4b into which the rod 2b can be inserted is formed. The scraping portion 4b is for removing excess stool adhering to the stool collection rod 2b when returning the stool collection rod 2b from which the stool has been collected into the container, and in the present embodiment, at the center of the bottom surface 4a. It is formed as an open cylindrical part. The scraping portion 4b is such that the stool collection rod 2b is in liquid-tight contact with the inner peripheral surface of the scraping portion 4b, and excess feces are removed when the stool collection rod 2b slides on the inner peripheral surface of the scraping portion 4b. Thus, a certain amount of stool filling the spiral groove 2 c can be suspended in the storage solution stored in the container body 3.

  The outer shape of the inner stopper 4 constituting the scraping portion 4b has a tapered shape that gradually decreases from the middle of the inner stopper 4 toward the scraping portion 4b in order to reliably guide the stool collection rod 2b to the scraping portion 4b. You can also.

However, in such a shape, a gap is formed between the side surface of the tapered portion and the inner surface of the container body, and the volume of the storage solution storage portion is increased. If the volume of the storage solution storage part is too large, the tip of the stool collection rod 2b will be in the air when the stool collection container 1 is placed sideways after being collected or stored with the drip cap 5 facing upward. It is also conceivable that the stability of the component to be measured in the stool is impaired due to exposure. For this reason, the shape of the inner plug 4 is preferably such that the volume of the storage solution storage portion is as small as possible.
Therefore, it is preferable that the outer shape of the inner plug 4 is substantially cylindrical, and the shape of the bottom surface 4a is a flat surface perpendicular to the longitudinal direction or a shape recessed from the periphery toward the central scraping portion 4b.

  Further, in the present embodiment, when the stool collection rod 2b from which the stool is collected is returned to the container, in order to facilitate the insertion of the stool collection rod 2b into the abrasion portion 4b, A stool collection rod guide portion including a plurality of inclined ribs 4c arranged radially is formed.

In the stool collection container 1, the inclined rib 4c is formed in a triangular shape having a side rising obliquely from the periphery of the scraping portion 4b, but if the stool collection rod 2b can be guided to the scraping portion 4b, The shape is not particularly limited.
In order to guide the stool collection rod 2b to the scraping portion 4b, it is only necessary to form a mortar around the scraping portion 4b. However, the bottom surface 4a side of the tip end portion of the inner plug 4 becomes thick and requires resin for molding. The quantity increases, and cooling takes time and the production speed is slowed down. Further, the shrinkage amount of the resin at the time of cooling becomes large, which is disadvantageous in terms of dimensional stability. However, a plurality of inclined ribs 4c are arranged in a radial manner, and the space between adjacent inclined ribs 4c is thinned to obtain a stool collection rod. Such inconvenience can be effectively avoided by forming the guide portion.

  The stool collection container 1 of the present embodiment is opened by suspending the dropping cap 5 after loosening the stool collected by the stool collection rod 2b in a preservation solution contained in the container body 3. Then, the container body 3 is squeezed, the suspension in which the stool is suspended in the storage solution is discharged from the extraction hole 3a and filtered through the filter 6 attached to the dropping cap 5, and the filtrate is dropped. It is intended for inspection.

  The filter 6 attached to the drip cap 5 can filter undigested solid matter that hinders inspection, and the material is not particularly limited as long as it is inert to the inspection target. Examples thereof include porous substances such as malt filters, filter papers, and resin sintered filters, and fibrous substances such as glass wool and absorbent cotton. It is preferable to use malt filters and resin sintered filters having a predetermined pore diameter. Such a filter may consist of one type or may be formed by stacking two or more types of filters.

  As a preservation solution for suspending the collected stool, any solution suitable for stool examination can be used. If necessary, a buffer, a stabilizer, a preservative, a dye, a disinfectant can be used. Additives such as odorants may be added. The amount of the storage solution stored in the container body is appropriately adjusted according to the stool suspension concentration required for the stool test. For example, when 5 mg of stool is collected, a dilution rate of 400 times can be obtained by setting the liquid volume to 2 ml.

  Furthermore, in the stool collection container 1, as shown in FIG. 8, the flange part 3c is formed along the edge of the opening part of the base end side of the container main body 3. As shown in FIG. On the other hand, on the outer peripheral surface of the inner plug 4 shown in FIG. 6 described above, a projecting portion 4d extending in the circumferential direction at a position overlapping the flange portion 3c of the container main body 3 when the inner plug 4 is mounted in the container main body 3. Is formed.

  As described above, the container body 3 is preferably formed into a cylindrical shape using a flexible material so that it can be squeezed. On the other hand, since the stool collection rod 2b adheres in a liquid-tight manner to the tip portion of the inner plug 4 and a scraping portion 4b is formed to remove excess feces, the inner plug 4 is molded using a hard material. Is preferred. In this case, since the container main body 3 and the inner plug 4 are formed of different materials that are difficult to weld, the lid 2 is attached to the inner plug 4 when the inner plug 4 mounted in the container main body 3 is fixed. It is desired to prevent the container main body 3 and the inner plug 4 from rotating freely or the co-rotation of the lid 2 and the inner plug 4 when attaching and detaching. For this reason, in the present embodiment, as shown in the drawing, the flange portion 3c formed on the container body 3 side is formed with an engaging portion including a notch portion 3f and an overhang formed on the inner plug 4 side. The container body 3 when the lid 2 having the stool collection rod 2b is attached to and detached from the inner plug 4 is formed by forming a locking part made up of the protrusion 4e fitted to the notch 3f on the part 4d. The idling of the inner plug 4 or the co-rotation of the lid 2 and the inner plug 4 is prevented.

  In addition, as an engaging part formed in the flange part 3c by the side of the container main body 3 mentioned above, the recessed groove part, a through-hole, etc. other than the notch part 3f are mentioned, The inside plug 4 side according to these shapes is mentioned. What is necessary is just to select suitably the shape of the latching | locking part formed in the overhang | projection part 4d. Further, the engaging portion described above may be formed in the overhanging portion 4d on the inner plug 4 side, and the locking portion may be formed on the flange portion 3c on the container main body 3 side.

  Further, the flange portion 3c formed on the container body 3 side and the overhang portion 4d formed on the inner plug 4 side are formed in a rhombus shape shown in the figure or in order to prevent rolling when the stool collection container 1 is inspected. An elliptical shape, a track shape, or the like is preferably formed so that one of two orthogonal directions is long.

  Further, as shown in FIGS. 3 and 10, a pair of blade portions 2d that facilitate the rotation of the lid body 2 are formed symmetrically on the lid portion 2a of the lid body 2, and the lower ends of the blade portions 2d. A pair of inclined grooves 2e are formed symmetrically by inflating the lower end side surface of the lid portion 2a of the lid portion 2 on the portion side into a hollow shape so that both sides on the upper side are inclined downward in a divergent shape. To do. On the other hand, as shown in FIGS. 6 and 9, a pair of inclined protrusions 4 f are formed on the inner periphery of the long diameter side of the overhanging portion 4 d of the inner plug 4. Form symmetrically. In this way, the lid 2 is placed by placing a finger on the blade portion 2d of the lid 2 by the detachment mechanism constituted by the sloped groove 2e of the lid 2 and the sloped protrusion 4f of the inner plug 4. By rotating, the lid body 2 can be easily detached from the inner plug 4.

  Note that the shape of both sides of the inclined groove portion 2e of the lid body 2 constituting the above-described detachment mechanism and the shape of both sides of the inclined projection portion 4f of the inner plug 4 make the rotation of the lid body 2 smooth. In order to eliminate the restriction of the rotation direction, it is preferable that the sides of the both sides and the sides of the inclined groove 2e and the inclined protrusion 4f have the same shape, and are linear or concave. It is preferable to make it into a shape.

  Furthermore, the inclined groove 2e of the lid 2 and the inclined protrusion 4f of the inner plug 4 do not need to be symmetrically formed as a pair, and any one of them may be formed. In addition, an inclined groove 2e formed on the lid 2 is formed on the side surface of the lower end of the lid 2a orthogonal to the blade 2d, and an inclined protrusion 4f formed on the inner plug 4 is formed on the short diameter side of the overhang 4d. The inclined groove portion 2e may be formed on the lower end side of the blade portion 2d of the lid portion 2a of the lid body 2, and the inclined projection portion 4f may be formed on the longer diameter side of the protruding portion 4d of the inner plug 4. Forming on the inner circumference is preferable from the viewpoint of facilitating the formation of each.

  In this case, when the lid body 2 is attached to the inner plug 4, the alignment of the inclined groove portion 2 e of the lid body 2 and the inclined protrusion portion 4 f of the inner plug 4 constituting the above-described detachment mechanism, and the lid The annular convex part 2f formed on the inner peripheral surface of the lid part 2a of the body 2 and the annular convex part 4g formed on the outer peripheral surface of the inner plug 4 are fitted. For this reason, as shown in FIG. 9, both sides are inclined downward in an inverted V shape with respect to the axial direction from the top side above the annular convex portion 4 g of the inner plug 4, and preferably the lower end portion is in the axial direction. A pair of guide cams 4h hanging in parallel is formed symmetrically. On the other hand, as shown in FIG. 10, a pair of ridges 2 h extending along the axial direction are formed symmetrically above the annular convex portion 2 f of the lid portion 2 a of the lid body 2. When the cam mechanism constituted by the guide cam 4h of the inner plug 4 and the protrusion 2h of the lid body 2 is rotated and pushed into the middle stopper 4 of the lid body 2 having the stool collection rod 2b, The protrusion 2h of the lid 2 is guided to the guide cam 4h of the inner plug 4. As a result, the lid body 2 can be easily and securely attached to the inner plug 4 in a state where the inclined groove portion 2e of the lid body 2 constituting the above-described detachment mechanism and the inclined protrusion portion 4f of the inner plug 4 are aligned. Can be fitted.

  Further, as described above, the flange portion 3c formed on the container body 3 side and the overhang portion 4d formed on the inner plug 4 side are formed so that one of the two directions perpendicular to each other is elongated, When the blade portion 2d is formed on the lid portion 2a, the guide cam 4h of the inner plug 4 of the cam mechanism described above is formed on the short diameter side of the protruding portion 4d of the inner plug 4, while the protrusion of the lid body 2 is formed. 2h is preferably formed at the same position as the blade portion 2d and the inclined groove portion 2e of the lid portion 2a. With such a configuration, sink marks at the time of molding of the lid portion 2a of the lid body 2 are prevented, and the blade portion 2d formed on the lid portion 2a is connected to the flange portion 3c formed on the container body 3. Positioned on the long diameter side of each of the overhang portions 4d formed in the inner plug 4.

  It should be noted that the protrusion 2h of the lid 2 and the guide cam 4h of the inner plug 4 do not have to be formed symmetrically, and either one may be formed. From the viewpoint of ease of mounting and fixing by fitting to the stopper 4 and stability, it is preferable that both are formed symmetrically as a pair. Further, the guide cam 4h of the inner plug 4 may be formed on the longer diameter side of the overhanging portion 4d, and the protrusion 2h of the lid 2 may be formed orthogonal to the blade portion 2d and the inclined groove portion 2e.

  Although the present invention has been described with reference to the preferred embodiment, it is needless to say that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. .

  For example, in the embodiment described above, the wear plug 4b is formed inside the container body 3 by mounting the inner plug 4 with the wear cut 4b formed in the container body 3. 4 may be omitted, and the scraped portion 4 b may be formed directly inside the container body 3.
