The present specification relates to an apparatus for storing and disinfecting an X-ray wireless detector, and specifically, it can easily disinfect and charge while preventing damage to the wireless detector, and can effectively sterilize and disinfect wireless detectors of various sizes. It relates to a storage and disinfection device for a ray wireless detector and an X-ray device including the same.

As X-ray inspection equipment has been replaced with digital equipment, detectors have become particularly important. The detector, which must be used for each patient during an X-ray examination, typically includes a scintillator, a photodiode, a TFT flat panel, and the like.

In particular, when a radiology examination is required for patients with reduced mobility, surgical procedures, or isolated patients, examinations are performed using a portable X-ray device with a wireless detector. For this purpose, a fixed detector in the past has recently been used as a wireless detector.

Since wireless detectors used in medical institutions are subject to contamination by secretions such as blood and sweat from patients and consequent infection and are always exposed to pathogens, it is inevitable to disinfect after use for each patient or isolated patient. However, there is a problem that the detector cover is corroded when the wireless detector is disinfected with a high-concentration disinfectant solution.

On the other hand, although devices for sterilizing the detector during movement have been disclosed, there is a problem in that appropriate sterilization and disinfection is not performed because the size of the wireless detector varies from manufacturer to manufacturer.

In order to solve the above problems, the present invention, on one side, is to provide an X-ray wireless detector storage and disinfection device that can easily disinfect and charge while preventing damage to the wireless detector.

In another aspect, the present invention is to provide an X-ray wireless detector storage and disinfection device that can effectively sterilize and disinfect wireless detectors of various sizes.

In embodiments of the present invention, as a device for storing and disinfecting a wireless detector applicable to a detector holder such as an X-ray device, a housing into which a wireless detector can be inserted, a housing mounted in the housing and contacted by the wireless detector and a lower support bar having a sterilization light irradiation unit, an upper light irradiation unit spaced apart from the wireless detector and capable of irradiating sterilization light from above the wireless detector, the size of the wireless detector, the position of the wireless detector, and the upper light irradiation unit. A sensor for measuring at least one of the light irradiation distance to the wireless detector and the light irradiation time of and the light irradiation distance (upper and/or side light irradiation distance) based on the value obtained by the sensor, the light irradiation source Provided is a device for storing and disinfecting wireless detectors including a control unit that controls at least one of the number and light irradiation time.

Embodiments of the present invention also provide an X-ray apparatus 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 to satisfy the following equation during the light irradiation.

[Equation 1]

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

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

According to embodiments of the present invention, disinfection and charging can be easily performed while preventing damage to the wireless detector. In particular, a stationary X-ray device can operate light irradiation such as UV directly using electricity, but an X-ray device including a wireless detector according to embodiments of the present invention uses electricity generated in the process of moving for several seconds ( sec) to several minutes (min) or sterilization is possible. As a result, UV disinfection can be easily performed in the process of storing the detector before/after imaging, effectively preventing contact infection caused by the detector.

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

In this specification, the light irradiation unit may include one or more light irradiation sources.

1 is an internal plan schematic view (FIG. 1A) and an internal side schematic diagram (FIG. 1B) of a device for storage and disinfection of a wireless detector according to an embodiment of the present invention.

As shown in FIG. 1, the device 1000 for storing and disinfecting a wireless detector applicable to a detector holder of an X-ray device includes a housing 500 into which a wireless detector D can be inserted, and the housing 500. ), a plurality of lower support bars 100 having a light irradiation part, which can support the wireless detector (D) by contacting the wireless detector (D), and a wireless detector (D) spaced apart from the wireless detector (D). It includes an upper light irradiation unit 200 capable of irradiating light from above.

Here, the lower support bar 100 may have, for example, a plurality of steel bars, preferably a plurality of steel bars having a network structure, and a light irradiation unit having a light irradiation source such as one or more UV irradiation lamps. The lower support bar 100 is disposed in the housing 500 such that the wireless detector D is inserted into the housing 500 at an angle, that is, such that the wireless detector D is inserted into the housing 500 with a certain inclination. Accordingly, the wireless detector D comes into contact with the lower support bar 100 and can maintain a constant distance from the light irradiator 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 measuring the distance on the lower support bar 100 side.

The upper light irradiation unit 200 may be a light irradiation unit having a light irradiation source such as one or more UV 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 UV irradiation unit 300 capable of irradiating sterilizing light to the wireless detector D from the side of the wireless detector D. there is.

The side light irradiation unit 300 may also have one or more light irradiation units such as light irradiation lamps installed in a steel bar shape.

On the other hand, the upper light irradiation unit 200 includes 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 top and/or side light irradiation unit, and the light irradiation time. One or more sensors (S) for sensing one or more are further provided.

As described above, the wireless detector D contacts the lower support bar 100 but is spaced apart from the upper light irradiation unit 200 by a certain distance. In addition, since light irradiation may not be properly performed depending on the size of the wireless detector D (see FIG. 3), the size of the wireless detector D through the sensor S, the location of the wireless detector D, Measuring at least one of the light irradiation distance to the wireless detector D of the upper and/or side light irradiation unit and the light irradiation time, and based on the measured value, the light irradiation distance (top and/or side light irradiation distance), It is necessary to adjust (control) at least one of the number of light irradiation sources and the light irradiation time.

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

The rear side of the wireless detector (D) is always in close contact with the lower support bar 100 so that it is easy to operate with a constant UV irradiation (light irradiation) intensity according to the setting of the medical staff, but the front side of the wireless detector (D) is the distance sensor (S) It is necessary to attach a plurality of, for example two or more, to the upper light irradiation unit 200 to adjust the intensity of UV irradiation (light irradiation) according to the distance from the wireless detector D.

The UV irradiation (light irradiation) intensity can be set differently (eg, 90%, 99%, 99.9%, etc.) according to the pathogen (virus, bacteria, etc.) to be disinfected, based on the disinfection value for known pathogens. It can be set initially. In addition, the corresponding disinfection value may be updated whenever recent data is updated, such as the intensity of UV irradiation (light irradiation) for a virus such as Covid-19. Meanwhile, as described later, since the sterilization effect decreases as the distance increases, the irradiation time (sec) should be included in the calculation formula in the direction of increasing.

As described above, the reason for locating the plurality of sensors (S) is to enable a distance measurement function even when the size of the detector (D) is small, and in the case of a small-sized detector (D), a light irradiation source such as an ultraviolet irradiation lamp This is to reduce power consumption by reducing the number or light irradiation time. That is, in the case of a small detector (D), it is possible to measure the distance even using one sensor, so it can be calculated by adjusting the irradiation time according to the UV irradiation intensity and the number of light irradiation sources, but most detectors (D ) can measure more accurate distance through the average of two or more sensors and set the irradiation time according to the calculation formula.

The apparatus 1000 for storing and disinfecting the wireless detector includes a controller (not shown) that controls (adjusts) light irradiation according to the sensing value as described above.

In one embodiment, the device 1000 for storage and disinfection of the wireless detector includes a transfer guide connected to the control unit and equipped with, for example, a motor capable of adjusting to drive a position of one or more of the upper light irradiation unit and the side light irradiation unit. It may further include a driving unit (not shown) including.

In order to increase or decrease the UV irradiation distance based on at least one of the size and position of the detector D sensed by the sensor S, the light irradiation distance, the number of light irradiation sources, and the light irradiation time, the drive unit is configured to increase or decrease the UV irradiation distance of the upper light irradiation unit. The steel bar and/or the steel bar of the side light irradiation part can be moved.

In one embodiment, the steel bar of the upper light irradiation unit and/or the steel bar of the side light irradiation unit may be transferred along a preset path and distance along the transfer guide.

In one embodiment, the control unit also controls a part 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). It can be controlled to operate only the light irradiation source (light irradiation lamp).

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

On the other hand, Figure 2 is a schematic diagram of each internal plane (Fig. 2a) and internal side schematic (Fig. 2b) of a device for storage and disinfection of a wireless detector according to another embodiment of the present invention.

As shown in FIG. 2 , a wireless charging coil 600 for charging an ultraviolet irradiator may be embedded in the housing 500 .

The wireless charging coil 600 may 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 more easily charged.

3 (a) to (c) are perspective schematic views of a storage and disinfection device for a wireless detector according to an embodiment of the present invention, showing that wireless detectors of various sizes are inserted.

As shown in (a) to (c) of FIG. 3, since the size of the wireless detector (D) varies, when it enters the housing 500, as described above, the size of the wireless detector (D), wireless At least one of the position of the detector D, the light irradiation distance from the top and/or side light irradiation unit to the wireless detector D, and the light irradiation time is sensed.

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

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, the top and side light irradiation sources Shows that only some of them are controlled to work.

5 is a flowchart showing an operation sequence according to an embodiment of the present invention.

As shown in FIG. 5 , when the cover of the device 1000 for storage and disinfection of the wireless detector is opened, sensor operation is checked. The sensor measures the light to detector, the sensor checks whether the UV lamp (light irradiation source), which is a sterilization light irradiation device, is operating, selects the desired disinfection level, and sets the desired disinfection time to proceed with disinfection. let it do

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

[Equation 2]

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

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

[Equation 3]

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

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

Embodiments of the present invention also provide an X-ray apparatus 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 corresponding to the size of the wireless detector. In addition, since the wireless detectors of the embodiments of the present invention include a wireless charging coil, sterilization can be sterilized from several seconds to several minutes or while moving using electricity generated in the process of moving. As a result, UV disinfection can be easily performed in the process of storing the detector before/after imaging, and infection can be effectively prevented.
