Description

{X-ray wireless detector storage and disinfection device}

The present specification relates to a storage and disinfection device for an X-ray wireless detector, and more particularly, to an X-ray wireless detector storage and disinfection device capable of easily performing disinfection and charging while preventing damage to the wireless detector, and effectively sterilizing and disinfecting wireless detectors of various sizes, and an X-ray device including the same.

As X-ray examination equipment is replaced by digital equipment, the detector has become particularly important. The detector is something that must be used on each patient during an X-ray examination, and usually includes a scintillator, a photodiode, a TFT flat panel, etc.

In particular, when a radiological examination is required for patients with limited mobility, surgical procedures, or isolated patients, a portable X-ray device with a wireless detector is used to conduct the examination. For this purpose, the trend is to use wireless detectors instead of fixed detectors in the past.

Wireless detectors used in medical institutions have the risk of contamination by secretions such as blood or sweat from patients, and thus infection, and are constantly exposed to pathogens. Therefore, they must be disinfected after each patient or after use for an isolated patient. However, there is a problem that the detector cover is corroded when disinfecting the wireless detector with high-concentration disinfectants.

Meanwhile, although a device for sterilizing a moving detector has been disclosed, there is a problem that proper sterilization and disinfection is not achieved because the sizes of wireless detectors vary by manufacturer.

Publication of Patent Publication No. 10-2012-0039254

In order to solve the above-described problems, the present invention, in one aspect, seeks to provide an X-ray wireless detector storage and sterilization device that can easily perform sterilization and charging while preventing damage to the wireless detector.

In another aspect, the present invention seeks to provide an X-ray wireless detector storage and disinfection device capable of effectively sterilizing and disinfecting wireless detectors of various sizes.

In embodiments of the present invention, a device for storing and sterilizing a wireless detector applicable to a detector holder of an X-ray device, the device includes a housing into which a wireless detector can be inserted, a lower support bar mounted in the housing and capable of supporting the wireless detector by contacting the wireless detector and having a sterilizing light irradiation unit, an upper light irradiation unit capable of irradiating sterilizing light from above the wireless detector at a distance from the wireless detector, a sensor for measuring at least one of the size of the wireless detector, the position of the wireless detector, the light irradiation distance from the upper light irradiation unit to the wireless detector, and the light irradiation time, and a control unit for adjusting at least one of the light irradiation distance (upper and/or side light irradiation distance), the number of light irradiation sources, and the light irradiation time based on the values obtained by the sensor.

Embodiments of the present invention also provide an X-ray device including a device for storing and disinfecting the wireless detector described above.

In an exemplary embodiment, the control unit controls the sterilizing capacity, the light irradiation intensity, the light irradiation time, and the distance between the light irradiation source and the wireless detector so that the following equations are satisfied.

[Formula 1]

Sterilization capacity = Light irradiation intensity (mW/ ^cm2 ) X Light irradiation time (sec) X (1/R) ²

Here, R is the distance between the light source and the wireless detector.

According to embodiments of the present invention, it is possible to easily perform sterilization and charging while preventing damage to the wireless detector. In particular, although a fixed X-ray device can directly operate light irradiation such as UV using electricity, an X-ray device including a wireless detector of embodiments of the present invention can perform sterilization for several seconds to several minutes or while moving by using electricity generated during the moving process. Accordingly, ultraviolet sterilization can be easily performed during the detector storage process before/after imaging examination, so that contact infection caused by the detector can be effectively prevented.

In addition, the devices of the embodiments of the present invention can effectively sterilize and disinfect wireless detectors of various sizes.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Although the embodiments illustrated in the drawings will be described below, they are described as exemplary embodiments, and the technical idea of the present invention and its core configuration and operation are not limited thereby.

In this specification, upper and lower or top and bottom should be understood as relative positional concepts. For example, it will be understood that if a device including parts referred to as upper and lower is flipped over, they can again be referred to as upper and bottom based on the direction in which they are flipped.

In this specification, light or sterilizing light is defined as light capable of performing sterilization and disinfection by light irradiation, and includes, for example, UV light.

In this specification, a light irradiation source may mean a light irradiation lamp, such as a UV lamp.

In this specification, the light irradiating portion may include one or more light irradiating sources.

FIG. 1 is a schematic diagram of each internal plane (FIG. 1a) and an internal side schematic diagram (FIG. 1b) of a device for storing and disinfecting a wireless detector according to one embodiment of the present invention.

As illustrated in FIG. 1, a device (1000) for storing and disinfecting a wireless detector that can be applied to a detector holder of an X-ray device includes a housing (500) into which a wireless detector (D) can be inserted, a plurality of lower support bars (100) mounted within the housing (500) and capable of supporting the wireless detector (D) by contacting the wireless detector (D) and having a light irradiation unit, and an upper light irradiation unit (200) that can irradiate light from above the wireless detector (D) at a distance from the wireless detector (D).

Here, the lower support bar (100) may be, for example, a plurality of steel bar shapes, preferably a plurality of steel bar shapes having a network structure, in which a light irradiation unit having one or more light irradiation sources, such as an ultraviolet irradiation lamp, is installed. The lower support bar (100) is arranged within the housing (500) such that the wireless detector (D) is obliquely inserted into the housing (500), that is, inserted with a constant inclination within the housing (500). Accordingly, the wireless detector (D) comes into contact with the lower support bar (100), and can maintain a constant distance from the light irradiation unit mounted on the lower support bar (100) regardless of the size of the wireless detector (D). Accordingly, since there is no need to measure the distance from the light irradiation unit of the lower support bar (100) to the wireless detector (D), there is no need to separately provide a sensor for distance measurement on the lower support bar (100) side.

The upper light irradiation unit (200) may be a light irradiation unit having one or more light irradiation sources, such as ultraviolet irradiation lamps, installed in a steel bar shape, like the lower support bar (100).

In one embodiment, the device (1000) for storing and disinfecting the wireless detector may further include a side ultraviolet irradiation unit (300) capable of irradiating germicidal light to the wireless detector (D) from the side of the wireless detector (D).

The side light irradiation unit (300) may also have one or more light irradiation units, such as a light irradiation lamp, installed in the shape of a steel bar.

Meanwhile, the upper light irradiation unit (200) is further provided with one or more sensors (S) for sensing one or more of the size of the wireless detector (D), the position of the wireless detector (D), the light irradiation distance to the wireless detector (D) of the upper and/or side light irradiation unit, and the light irradiation time.

As described above, the wireless detector (D) is in contact with the lower support bar (100) but is a certain distance away from the upper light irradiation unit (200). In addition, since light irradiation may not be performed appropriately depending on the size of the wireless detector (D) (see FIG. 3), it is necessary to measure at least one of the size of the wireless detector (D), the position of the wireless detector (D), the light irradiation distance from the upper and/or side light irradiation unit to the wireless detector (D), and the light irradiation time through the sensor (S), and adjust (control) at least one of the light irradiation distance (upper and/or side light irradiation distance), the number of light irradiation sources, and the light irradiation time based on the measured values.

In one embodiment, the number of sensors may be two or more, and an average of measurement values of two or more sensors may be used.

It is easy to operate the rear of the wireless detector (D) at a constant UV irradiation (light irradiation) intensity according to the medical staff setting by always keeping it in close contact with the lower support bar (100), but it is necessary to attach a plurality of distance sensors (S), for example, two or more, to the upper light irradiation section (200) on the front of the wireless detector (D) to adjust the UV irradiation (light irradiation) intensity according to the distance from the wireless detector (D), etc.

The above UV irradiation (light irradiation) intensity can be set differently (e.g., 90%, 99%, 99.9%, etc.) depending on the pathogen to be disinfected (virus, bacteria, etc.), and can be initially set based on the disinfection value for a known pathogen. In addition, the disinfection value can be updated whenever the latest data is updated, such as the UV irradiation (light irradiation) intensity for a virus such as COVID-19. Meanwhile, as described later, since the sterilization effect decreases as the distance increases, the calculation formula should include an increase in the irradiation time (sec).

As described above, the reason for positioning multiple sensors (S) is to enable the distance measurement function even if the detector (D) size is small, and in the case of a small-sized detector (D), to reduce the number of light irradiation sources such as UV irradiation lamps or the light irradiation time, thereby reducing power consumption. That is, in the case of a small detector (D), distance measurement is possible even with one sensor, and the irradiation time can be adjusted and calculated according to the UV irradiation intensity and the number of light irradiation sources, but most detectors (D) of a certain size can measure a more accurate distance through the average value of two or more sensors, and set the irradiation time according to the calculation formula.

The above wireless detector storage and disinfection device (1000) includes a control unit (not shown) that controls (regulates) light irradiation as described above according to the sensing value.

In one embodiment, the device (1000) for storing and disinfecting the wireless detector may further include a driving unit (not shown) including a transport guide, for example, equipped with a motor, which is connected to the control unit and can be adjusted to drive the position of one or more of the upper light irradiation unit and the side light irradiation unit.

The driving unit can move the steel bar of the upper light irradiation unit and/or the steel bar of the side light irradiation unit to increase or decrease the ultraviolet irradiation distance based on one or more of the detector (D) size and position sensed by the sensor (S), the light irradiation distance, the number of light irradiation sources, and the light irradiation time.

In one embodiment, the steel bar of the upper light irradiator and/or the steel bar of the side light irradiator may be transported along the transport guide along a preset path and distance.

In one embodiment, the control unit may also control to operate only some of the light irradiation sources (light irradiation lamps) adjacent to the wireless detector (D) when the size of the wireless detector (D) sensed by the sensor (S) is small and there is no need to operate all of the light irradiation sources (light irradiation lamps).

In one embodiment, the device (1000) for storing and disinfecting the wireless detector may further include a display unit (400) that displays a disinfection time and/or a disinfection status. The display unit (400) may be located together with the control unit or may be located independently, and may display a sterilization light disinfection time and/or a disinfection status according to a control result of the control unit.

Meanwhile, FIG. 2 is a schematic diagram of each internal plane (FIG. 2a) and internal side view (FIG. 2b) of a device for storing and disinfecting a wireless detector according to another embodiment of the present invention.

As shown in Fig. 2, a wireless charging coil (600) for charging the ultraviolet ray irradiation unit may be built into the housing (500).

The above wireless charging coil (600) can be mounted on the lower support bar (100) side and/or the upper ultraviolet irradiation unit (200) side. Accordingly, the wireless detector (D) can be charged more easily.

Figures 3 (a) to (c) are perspective schematic diagrams of a storage and sterilization device for a wireless detector according to one embodiment of the present invention, showing wireless detectors of various sizes incorporated therein.

As shown in (a) to (c) of FIG. 3, the size of the wireless detector (D) varies, so when it enters the housing (500), as described above, one or more of the size of the wireless detector (D), the position of the wireless detector (D), the light irradiation distance from the upper and/or side light irradiation portion to the wireless detector (D), and the light irradiation time is sensed through the sensor.

FIG. 4 is a schematic diagram of the inside of a device for storing and sterilizing a wireless detector according to one embodiment of the present invention, showing that only a part of the light irradiation source operates when the size of the wireless detector is small ((c) of FIG. 3).

As shown in Fig. 4, when the size of the wireless detector (D) sensed by the sensor (S) is small and the position of the wireless detector (D) can be covered by a part of the light irradiation source, it is shown that only a part of the upper and side light irradiation sources are controlled to operate.

Figure 5 is a flowchart showing an operating sequence according to one embodiment of the present invention.

As shown in Fig. 5, when the cover of the device (1000) for storing and disinfecting the wireless detector is open, the sensor operation is confirmed. The sensor measures the operating distance (Light to Detector), the sensor confirms whether the UV lamp (light irradiation source), which is a sterilizing light irradiation device, is operating, the desired disinfection level is selected, and the desired disinfection time is set to proceed with disinfection.

At this time, the disinfection time is set according to the preset formula 2 below.

[Formula 2]

Sterilization Dosage = UV irradiation intensity (UV light Intensity) (mW/cm ² ) X UV irradiation time (sec)

Here, the UV irradiation intensity (light irradiation intensity) is a value at the surface of the wireless detector (D), and the UV irradiation intensity (light irradiation intensity) emitted from the UV irradiation lamp (light irradiation source) may decrease depending on the distance (R) between the UV irradiation lamp (light irradiation source) and the wireless detector (D), so it is necessary to reflect the decrease rate of the UV irradiation intensity (light irradiation intensity). To this end, the above-described equation is corrected as in the correction calculation equation (Equation 3) below so that the square value of the reciprocal of the distance (R) is reflected.

[Formula 3]

Sterilization Dosage = UV irradiation intensity (UV light Intensity) (mW/cm ² ) X UV irradiation time (sec) X (1/R) ²

For example, if the 99% sterilization Dosage is 20 and the UV irradiation intensity (UV light Intensity) (based on a 1 cm distance between the UV irradiation lamp and the object) is 10, the irradiation time is 2 seconds, but considering that the distance from the detector (D) surface to the UV irradiation lamp is 3 cm, the time required for UV irradiation is 18 seconds [i.e., 20 = 10 * (1/3) ² * 18 seconds].

Embodiments of the present invention also provide an X-ray device including a device for storing and disinfecting the wireless detector described above.

In one embodiment, the device may be, for example, a portable X-ray device.

As described above, according to the embodiments of the present invention, effective sterilization and disinfection of the wireless detector can be performed in accordance with the size of the wireless detector. In addition, since the wireless detector of the embodiments of the present invention includes a wireless charging coil, sterilization is possible for several seconds (sec) to several minutes (min) or during movement by using the electricity generated during the movement process. Accordingly, ultraviolet sterilization can be easily performed during the detector storage process before/after the imaging examination, so that infection can be effectively prevented.
