Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority based on Japanese Patent Application No. 2020-207321 filed on December 15, 2020, and Japanese Patent Application No. 2021-202505 filed on December 14, 2021, the entire contents of which are incorporated herein by reference. Technical Field

[0003] An embodiment of the present invention relates to a packaging replacement device. Background Art

[0004] When X-ray photography is performed during the observation of COVID-19 (coronavirus disease 2019: new coronavirus infection) patients, a portable X-ray device is used. In addition, the portable X-ray device is used as a guide for VV-ECMO (Extra Corporeal Membrane Oxygenation) for COVID-19 patients. When X-ray photography is performed using a portable X-ray device, in order to prevent infection, the FPD (Flat Panel Detector) used as an X-ray detector is double-wrapped with a plastic bag to perform X-ray photography. And, every time the photography of one patient is completed, only the outer plastic bag is replaced with a sterilized new plastic bag. When replacing the outer plastic bag, in order to prevent infection, it must be replaced in a manner that does not touch the inner plastic bag. Therefore, first, one operator removes about half of the outer plastic bag. Then, the other operator receives the FPD wrapped in the inner plastic bag while a new plastic bag is prepared. In this way, only the outer plastic bag is re-wrapped without touching the inner plastic bag. Since such operation is necessary, two operators are required. In addition, such operation is very laborious because it requires careful and concentrated work.

[0064] Below, while referring to the attached Figure 1 The embodiment of the packaging replacement device is described in detail. The packaging replacement device can peel off the used bag from the medical device covered by the used bag, and cover the medical device from which the used bag has been peeled with a new bag. Examples of medical devices include portable devices such as X-ray detectors and ultrasonic probes. In the following description, components having substantially the same function and structure are given the same reference numerals, and repeated descriptions are given only when necessary.

[0065] (First embodiment)

[0066] Figure 1 1 is a diagram showing the configuration of a package replacement device 1 according to the present embodiment. The package replacement device 1 according to the present embodiment replaces the package covering an FPD (Flat Panel Detector) 100 used as an X-ray detector. Figure 2 and Figure 3 It is a diagram showing the structure of FPD100. Figure 4 and Figure 5 1 is a diagram showing the internal structure of the packaging replacement device 1. The packaging replacement device 1 is a device that peels off the first bag 200 from the FPD100 covered by the first bag 200 and automatically covers the FPD100 with the second bag 300. The packaging replacement device 1 can also be called an automatic packaging device. FPD100 is a planar X-ray detector used in X-ray photography using a portable X-ray device. FPD100 converts X-rays that are irradiated on the subject and pass through the subject into electric charges and accumulates them. The size of FPD100 is, for example, a value in the range of 8 to 16 inches. FPD100 is composed of tiny detection elements arranged two-dimensionally in the column direction and the row direction. Each detection element has a photoelectric film that senses X-rays and generates electric charges corresponding to the amount of incident X-rays, a charge storage capacitor that stores the electric charges generated in the photoelectric film, and a TFT (thin film transistor) that outputs the electric charges stored in the charge storage capacitor at a specified timing.

[0067] The first bag 200 and the second bag 300 are sterilized covers that cover the FPD 100 to prevent infection during X-ray examinations of infectious patients such as COVID-19. The first bag 200 is, for example, a used plastic bag attached to the FPD 100 used in X-ray photography of infectious patients. The second bag 300 is a new sterilized plastic bag that has not been used so far.

[0068] like Figure 2 and Figure 3As shown, FPD100 is formed in a plate shape. FPD100 includes a top surface 101, two side surfaces 102, a bottom surface 103, a surface 106, and a back surface 107. The top surface 101 is a surface facing the opposite side relative to the bottom surface 103, and is the surface that is last inserted relative to the packaging replacement device 1. The bottom surface 103 is a surface that is first inserted relative to the packaging replacement device 1. One side surface 102 is a surface facing the opposite side relative to the other side surface 102. The surface 106 includes a detection surface on which the above-mentioned detection elements are arranged, and is a surface facing the opposite side relative to the back surface 107. The surface 106 and the back surface 107 form the widest surface among the surfaces of FPD100.

[0069] Here, the direction in which the top surface 101 or the bottom surface 103 faces is defined as the height direction of the FPD 100 , the direction in which the side surface 102 faces is defined as the width direction of the FPD 100 , and the direction in which the surface 106 and the back surface 107 face is defined as the thickness direction of the FPD 100 . Figure 2 1 is a diagram of the FPD 100 viewed from the surface 106 side in the thickness direction. Figure 3 This is a diagram of the FPD 100 as viewed from the top surface 101 side.

[0070] Grooves 104 are provided on the side surfaces 102. The grooves 104 are recessed from the side surfaces 102 toward the inside in the width direction. The grooves 104 are provided at the center of the side surfaces 102 in the thickness direction and extend in the height direction. The grooves 104 are provided over the entire side surfaces 102 in the height direction.

[0071] A groove 105 is provided on the bottom surface 103. The groove 105 is a recessed portion that is recessed from the bottom surface 103 toward the top surface 101 in the height direction. The groove 105 is provided in the center of the side surface 103 in the thickness direction and extends in the width direction. The groove 105 is provided across the entire bottom surface 103 in the width direction.

[0072] When the plastic bag is attached to the FPD 100, the plastic bag is in close contact with the surface of the FPD 100 from the outside. However, in the portion where the groove 104 is provided, the plastic bag does not contact the surface of the side surface 102, and a gap is formed between the bottom surface of the groove 104 and the plastic bag. Similarly, in the portion where the groove 105 is provided, the plastic bag does not contact the surface of the bottom surface 103, and a gap is formed between the bottom surface of the groove 105 and the plastic bag.

[0073] Next, the internal structure of the packaging replacement device 1 is described in detail. Figure 4 and Figure 5 As shown, the package replacing device 1 includes a housing 2 , a pair of rollers 3 , a side surface cutting mechanism 4 , a bottom surface cutting mechanism 5 , a packaging mechanism 6 , and a removal port 8 .

[0074] The roller 3 functions as an insertion port into which the FPD 100 is inserted. The FPD 100 wrapped in the first bag 200 is inserted between the pair of rollers 3. The pair of rollers 3 sandwich the FPD 100 wrapped in the first bag 200 to hold the FPD 100. The pair of rollers 3 each has an axis member 30 as a central axis, and rotates relative to the housing 2 around the central axis. The pair of rollers 3 rotates while holding the FPD 100 wrapped in the first bag 200, thereby conveying the FPD 100 to the lower side. The rollers 3 function as a conveying mechanism for conveying the FPD 100 wrapped in the first bag 200.

[0075] Here, the direction along the central axis of the roller 3 is defined as the X axis. In addition, the direction perpendicular to the X axis and horizontal to the Y axis is defined as the Z axis. The Z axis coincides with the plumb bob direction. Figure 4 This is a diagram showing the internal structure of the package replacing device 1 in a cross section perpendicular to the X-axis. Figure 5 This is a diagram showing the internal structure of the package replacing device 1 in a cross section perpendicular to the Y axis.

[0076] The side cutting mechanism 4 and the bottom surface cutting mechanism 5 cut the first bag 200 covering the FPD 100 conveyed by the roller 3 along the grooves 104 and 105 provided on the FPD 100, respectively. The side cutting mechanism 4 and the bottom surface cutting mechanism 5 correspond to the cutting mechanism.

[0077] The side cutting mechanism 4 is fixed above the shaft member 30 of the roller 3 and cuts the portion of the first bag 200 attached to the side surface 102 of the FPD 100 by conveying the FPD 100 downward by the roller 3 while being arranged inside the groove 104 .

[0078] The bottom surface cutting mechanism 5 moves in the groove 105 along the width direction of the FPD 100 while the FPD 100 is held between the rollers 3 , thereby cutting a portion of the first bag 200 attached to the bottom surface 103 of the FPD 100 .

[0079] The rollers 3 convey the FPD 100 downward, and peel the first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 from the FPD 100, and wind up the peeled first bag 200. The pair of rollers 3 corresponds to a peeling mechanism.

[0080] The packaging mechanism 6 fixes the second bag 300 . The FPD 100 from which the first bag 200 has been peeled off by the roller 3 is inserted into the second bag 300 fixed by the packaging mechanism 6 .

[0081] The take-out port 8 is provided at a position different from the inlet where the FPD 100 is inserted. That is, the take-out port 8 is provided at a position different from the portion where the roller 3 is provided in the housing 2. The FPD 100 wrapped by the second bag 300 is taken out from the inside of the housing 2 at the take-out port 8. Here, the side in the Y-axis direction where the take-out port 8 is installed is referred to as the front side. In addition, the side in the Y-axis direction where the take-out port 8 is not installed is referred to as the back side.

[0082] Furthermore, the package replacing device 1 includes a control device. The control device includes a processing circuit and a memory.

[0083] The memory is a storage device such as a HDD (Hard Disk Drive) or SSD (Solid State Drive), an integrated circuit, etc. that stores various information. In addition to HDD, SSD, etc., the memory may also be a removable storage medium such as a CD (Compact Disc), DVD (Digital Versatile Disc), flash memory, etc. In addition, the memory may also be a drive device that reads and writes various information between a semiconductor memory element such as a flash memory, RAM (Random Access Memory), etc.

[0084] The processing circuit controls the overall operation of the package replacement device 1. The processing circuit is a processor that controls the operation and drive of each element constituting the package replacement device 1.

[0085] The term "processor" used in the above description refers to, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or an ASIC, a programmable logic device (for example, a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)). The processor implements its functions by reading and executing a program stored in a memory. In addition, instead of storing the program in the memory, the program can be directly loaded into the circuit of the processor. In this case, the processor implements its functions by reading and executing the program loaded in the circuit. In addition, the processor of the present embodiment is not limited to the case where the processor is configured as a single circuit, and multiple independent circuits can be combined to form one processor to implement its functions. The above description of the "processor" is the same in the following embodiments and modified examples.

[0086] Hereinafter, the above-mentioned components will be described in detail respectively.

[0087] The rollers 3 are installed inside the housing 2. The rollers 3 are cylindrical rod-shaped members extending horizontally. The rollers 3 are installed on the housing 2 via shaft members 30 extending horizontally. The shaft members 30 are the central axes of the rollers 3. The shaft members 30 are connected to driving devices such as motors. The rollers 3 are driven by the driving devices to rotate relative to the housing 2 around the shaft members 30. At this time, one side of the rollers 3 rotates to the opposite side relative to the other side.

[0088] The rollers 3 hold the FPD 100 inserted between the rollers 3 by clamping it. At this time, the FPD 100 is held between the rollers 3 in a state where the top surface 101 faces upward, the bottom surface 103 faces downward, and the width direction is parallel to the shaft member 30 of the rollers 3. The rollers 3 rotate while holding the FPD 100, and convey the held FPD 100 downward at a predetermined speed.

[0089] The material forming the roller 3 is, for example, rubber. In addition, the outer peripheral surface of the roller 3 has adhesiveness. As a means for making the outer peripheral surface of the roller 3 have adhesiveness, for example, the roller 3 is formed of a material with high adhesiveness, or a sheet with adhesiveness is attached to the outer surface of the roller 3. The roller 3 conveys the FPD 100 wrapped with the first bag 200 to the lower side, and makes the first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 adhere to the outer surface, thereby peeling the first bag 200 from the FPD 100, and winding the peeled first bag 200.

[0090] The side cutting mechanism 4 is fixed to the inner wall of the housing 2. The side cutting mechanism 4 is arranged slightly above the shaft member 30 of the roller 3. The side cutting mechanism 4 includes a cutter for cutting the portion of the first bag 200 mounted on the side 102 of the FPD 100. When the FPD 100 mounted with the first bag 200 is conveyed downward by the roller 3, the cutter of the side cutting mechanism 4 moves along the Z axis inside the groove 104 of the side 102, and the portion of the first bag 200 covering the FPD 100 mounted on the side 102 is cut by the cutter.

[0091] The bottom surface cutting mechanism 5 is installed inside the housing 2 at a lower side than the roller 3 in a state where it can move along the X-axis. The bottom surface cutting mechanism 5 is connected to a driving device such as a motor. The bottom surface cutting mechanism 5 is driven by the driving device to move relative to the housing 2 along the X-axis. The bottom surface cutting mechanism 5 cuts the portion of the first bag 200 covering the FPD 100 that is installed on the bottom surface 103 of the FPD 100 by moving relative to the housing 2 along the X-axis. The bottom surface cutting mechanism 5 is normally stored in the retracted position and moves from the retracted position to the lower side of the roller 3 only when in use. For example, when the length of the housing 2 in the X-axis direction is sufficiently larger than the length of the roller 3, the retracted position is configured at the end of the housing 2 in the X-axis direction.

[0092] As an example, the structure of the bottom surface cutting mechanism 5 having an L-shaped arm is described. In this structural example, the bottom surface cutting mechanism 5 includes a track fixed on the inner wall of the housing 2, an L-shaped arm that can move on the track by being driven by a motor, and a cutter installed on the front end of the L-shaped arm. The track is extended along the X-axis. In addition, the L-shaped arm includes a first rod-shaped portion whose base end is installed on the track and extends along the Y-axis, and a second rod-shaped portion extending from the front end of the first rod-shaped portion toward the upper side. In addition, a cutter for cutting the first bag 200 installed on the FPD100 is installed on the upper end of the second rod-shaped portion. If the L-shaped arm moves on the track, the cutter moves along the X-axis inside the groove 105 of the bottom surface 103, and the portion of the first bag 200 covering the FPD100 installed on the bottom surface 103 is cut by the cutter.

[0093] The packaging mechanism 6 is fixed inside the housing 2. The packaging mechanism 6 is arranged below the roller 3. The packaging mechanism 6 includes a fixing mechanism and a sealing mechanism. The fixing mechanism fixes the second bag 300 to the lower side of the roller 3 in a state where the opening is opened toward the gap between the rollers 3 on the upper side. For example, the fixing mechanism may fix the second bag 300 by holding the opening of the second bag 300.

[0094] The sealing mechanism seals the opening of the second bag 300 into which the FPD 100 is inserted. For example, the sealing mechanism seals the opening of the second bag 300 by pressing it from both sides and applying heat. The sealing mechanism may also be referred to as a sealing machine.

[0095] The take-out port 8 is provided below the roller 3 and the packaging mechanism 6. The take-out port 8 includes an opening and closing opening opened and closed by an operator's operation. When the opening and closing opening is opened relative to the housing 2, the FPD 100 can be taken out from the inside of the housing 2 to the outside.

[0096] A guide mechanism for controlling the posture of FPD 100 may be provided between roller 3 and packaging mechanism 6 and between packaging mechanism 6 and outlet 8. The guide mechanism is, for example, a roller. When the guide mechanism is provided, the stability of conveyance of FPD 100 in housing 2 is improved.

[0097] Next, refer to Figures 6 to 9 , the operation of the packaging replacement device 1 according to this embodiment will be described.

[0098] When replacing the first bag 200 covering the FPD 100 with the second bag 300 using the package replacement device 1 , the operator first inserts the FPD 100 covered by the first bag 200 between the pair of rollers 3 . Figure 6 1 is a diagram showing a state where the FPD 100 covered by the first bag 200 is inserted between the rollers 3. The inserted FPD 100 is sandwiched by the rollers 3 and fixed between the rollers 3.

[0099] Next, the operator inputs an operation to start replacing the bag covering the FPD 100 by operating an operation button (not shown) or the like. When the operation to start replacing the bag covering the FPD 100 is input, the package replacement device 1 first drives the drive device connected to the bottom surface cutting mechanism 5, thereby moving the bottom surface cutting mechanism 5 along the X axis slightly below the FPD 100 disposed between the rollers 3. At this time, the cutter of the bottom surface cutting mechanism 5 is moved along the groove 105 disposed on the bottom surface 103 of the FPD 100, thereby cutting the portion of the first bag 200 attached to the bottom surface 103.

[0100] When the cutting of the first bag 200 mounted on the bottom surface 103 is completed, the package replacing device 1 drives the driving devices connected to the rollers 3 to rotate the rollers 3 and convey the FPD 100 held between the rollers 3 downward. Figure 7 1 is a diagram showing a state where the FPD 100 held between the rollers 3 is conveyed downward. At this time, the cutter of the side cutting mechanism 4 moves along the groove 104 provided on the side 102 of the FPD 100, thereby cutting the portion of the first bag 200 mounted on the side 102. The first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 is adhered to the outer surface of the roller 3 by the adhesiveness of the outer surface of the roller 3. Furthermore, if the roller 3 rotates in a state where the cut first bag 200 is adhered to the outer surface of the roller 3, the FPD 100 is conveyed downward, and at the same time, the first bag 200 is peeled off from the FPD 100, and the cut first bag 200 is respectively wound by the roller 3. The FPD 100 after the first bag 200 is peeled off is inserted into the inside of the second bag 300 fixed to the fixing mechanism of the packaging mechanism 6.

[0101] When the FPD 100 is inserted into the second bag 300 , the package replacing device 1 drives the driving device connected to the sealing mechanism to seal the opening of the second bag 300 into which the FPD 100 is inserted. Figure 8 1 is a diagram showing a state in which the opening of the second bag 300 is sealed. By sealing the opening of the second bag 300 , the FPD 100 from which the first bag 200 has been peeled off is wrapped with the second bag 300 .

[0102] When the FPD 100 is wrapped with the second bag 300 , the package replacement device 1 conveys the FPD 100 wrapped with the second bag 300 to the removal port 8 . The operator can take out the FPD 100 wrapped with the second bag 300 from the inside of the housing 2 to the outside by opening the removal port 8 . Fig. 9 1 and 2 are diagrams showing a state where the removal port 8 is opened. After the operator changes the gloves that have touched the first bag 200 , the operator takes out the FPD 100 covered by the second bag 300 from the removal port 8 .

[0103] When the FPD 100 wrapped with the second bag 300 is taken out, the operator peels off the wound first bag 200 from the roll 3 and collects it in order to replace the bag for the next FPD 100. Then, the new second bag 300 is set on the packaging mechanism 6.

[0104] Hereinafter, the effects of the package replacing device 1 according to the present embodiment will be described.

[0105] The package replacement device 1 according to the present embodiment includes a peeling mechanism that peels the first bag 200 from the FPD 100 wrapped in the first bag 200 , and a packaging mechanism that wraps the FPD 100 from which the first bag 200 has been peeled with the second bag 300 .

[0106] According to the above structure, the peeling mechanism peels the first bag 200 from the FPD 100, and the packaging mechanism wraps the FPD 100 with the second bag 300, so that the anti-infection bag wrapping the FPD 100 can be easily replaced. That is, according to the packaging replacement device 1 related to this embodiment, the anti-infection bag wrapping the X-ray detector can be automatically and easily replaced. Therefore, the operator can replace the bag wrapping the X-ray detector without concentrating.

[0107] Furthermore, since it is not necessary to replace the FPD 100 while holding it, the FPD 100 wrapped in the second bag 300 can be taken out after replacing the gloves that have grasped the first bag 200. Therefore, the bag wrapping the FPD 100 can be replaced by one person. In addition, the bag wrapping the FPD 100 can be set to one piece.

[0108] Furthermore, the package replacement device 1 includes an insertion port for inserting the FPD 100 and a removal port 8 for removing the FPD 100 wrapped in the second bag 300. The insertion port is provided at a position where the roller 3 is arranged. The removal port 8 is provided at a position different from the insertion port.

[0109] According to the above configuration, the FPD 100 covered by the second bag 300 can be taken out at a position different from the insertion port of the first bag 200. Therefore, bacteria or viruses attached to the first bag 200 can be reliably prevented from attaching to the second bag 300 mounted on the FPD 100.

[0110] The peeling mechanism includes a pair of rollers 3 that sandwich and hold the FPD 100 wrapped in the first bag 200 . The pair of rollers 3 rotates while holding the FPD 100 wrapped in the first bag 200 , thereby conveying the FPD 100 wrapped in the first bag 200 .

[0111] According to the above configuration, the FPD 100 can be held between the rollers 3. Furthermore, by rotating the rollers 3 while holding the FPD 100, the FPD 100 can be automatically conveyed into the housing 2 at a predetermined speed.

[0112] Furthermore, the package replacing device 1 further includes a cutting mechanism for cutting the first bag 200 covering the FPD 100 along the groove provided in the FPD 100 .

[0113] The cutting mechanism comprises: a bottom cutting mechanism 5, which cuts a portion of the first bag 200 mounted on the bottom surface 103 of the FPD100 by moving along the width direction of the FPD100 in the groove 105 provided on the bottom surface 103 of the FPD100; and a side cutting mechanism 4, which is fixed on the upper side of the shaft part 30 of the roller 3, and cuts a portion of the first bag 200 mounted on the side surface 102 of the FPD100 by conveying the FPD100 to the lower side by the roller 3 in a state of being arranged in the groove 104 provided on the side surface 102 of the FPD100.

[0114] According to the above structure, according to the package replacement device 1 of the present embodiment, when the FPD 100 covered with the first bag 200 for X-ray inspection is placed between the rollers 3, the first bag 200 mounted on the bottom surface 103 of the FPD 100 can be automatically cut by the operation of the bottom surface cutting mechanism 5. Then, the FPD 100 is automatically conveyed to the inside of the housing 2 by the rotation of the rollers 3. At this time, the first bag 200 mounted on the side surface 102 of the FPD 100 can be automatically cut by the side surface cutting mechanism 4.

[0115] The outer peripheral surface of the roller 3 has adhesiveness. The FPD 100 is conveyed downward by the roller 3 , and the first bag 200 peeled from the FPD 100 is wound around the roller 3 .

[0116] According to the above configuration, by rotating the roller 3 while the infection prevention bag covering the FPD 100 is adhered to the surface of the roller 3 , the infection prevention bag can be efficiently peeled off from the FPD 100 and the peeled bag can be efficiently wound up.

[0117] (Variation of the first embodiment)

[0118] The roller 3 may be disposed after use. For example, the roller 3 wound with the first bag 200 may be disposed and replaced with a new roller 3 each time the bag for one FPD 100 is replaced. In this case, since the peeled first bag 200 can be disposed according to the roller 3, the labor of peeling the first bag 200 wound on the roller 3 from the roller 3 can be saved. In addition, since the peeled first bag 200 can be disposed without directly touching the first bag 200, it is also preferable in terms of hygiene.

[0119] (Second embodiment)

[0120] The second embodiment will be described. In this embodiment, the structure of the first embodiment is modified as follows. The description of the same structure, operation, and effect as those of the first embodiment will be omitted.

[0121] In the package replacement device 1 according to the present embodiment, instead of providing the roller 3 with adhesiveness and providing the protrusion 35 on the roller 3, the first bag 200 is provided with the engaging portion 210 that can engage with the protrusion 35. Then, the FPD 100 covered with the first bag 200 is arranged between the rollers 3, and the rollers 3 are rotated in a state where the engaging portion 210 is engaged with the protrusion 35, so that the FPD 100 is conveyed and the first bag 200 peeled from the FPD 100 is wound onto the roller 3.

[0122] Fig.10 2 is a diagram showing the structure of the packaging replacement device 1 according to the present embodiment. Fig.10 As shown in the figure, the roller 3 is provided with a cylindrical portion 31 and two protrusions 35. The cylindrical portion 31 is a cylindrical rotating body extending in the X-axis direction. The protrusions 35 protrude outward from both end surfaces in the X-axis direction. The protrusions 35 are provided at a position away from the shaft member 30 in a cross section perpendicular to the X-axis. As the roller 3 rotates, the protrusions 35 rotate around the shaft member 30.

[0123] Below, refer to Fig.11 , the structure of the bag used in this embodiment is described. Fig.11In the embodiment, the first bag 200 is described as an example. The second bag 300 has the same structure as the first bag 200.

[0124] Fig.11 FIG. 2 is a diagram showing a state where the FPD 100 used in the package replacement device 1 of the present embodiment is wrapped by the first bag 200. Fig.11 As shown, a plurality of engaging portions 210 are provided on the first bag 200 .

[0125] The engaging parts 210 are ring-shaped hooking parts. One engaging part 210 is installed at each of the four corners of the bottom surface 103 in the first bag 200 when the first bag 200 is installed on the FPD 100. The engaging part 210 is formed of the same material as the first bag 200. The engaging part 210 can also be formed of a resin material.

[0126] The engagement portions 210 are each formed in a shape that can engage with one of the protrusions 35 of the roller 3. The engagement portions 210 are each formed in a ring shape having a diameter slightly larger than that of the protrusion 35.

[0127] In addition, it is sufficient that at least one protrusion 35 is provided on each roller 3. In the present embodiment, two protrusions 35 are provided on each of the pair of rollers 3. Therefore, in the present embodiment, a total of four protrusions 35 are provided. The first bag 200 is provided with the same number of engaging portions 210 as the total number of the protrusions 35. Therefore, in the present embodiment, four engaging portions 210 are provided. The number of the engaging portions 210 may be less than the total number of the protrusions 35, or may be more than the total number of the protrusions 35.

[0128] The shapes of the protrusion 35 and the engaging portion 210 may be any shapes that can engage with each other. Alternatively, the first bag 200 may be provided with a protrusion, and the roller 3 may be provided with an annular engaging portion that engages with the protrusion.

[0129] Next, refer to Fig.12 , the operation of the packaging replacement device 1 according to this embodiment will be described.

[0130] When replacing the first bag 200 covering the FPD 100 with the second bag 300 using the package replacement device 1 , the operator first inserts the FPD 100 covered by the first bag 200 between the pair of rollers 3 and fixes the FPD 100 between the rollers 3 . Fig.12 The figure shows a state where the FPD 100 covered by the first bag 200 is inserted between the rollers 3. At this time, the operator hooks the engaging parts 210 attached to the first bag 200 onto the corresponding protrusions 35. Thus, the engaging parts 210 and the protrusions 35 are engaged.

[0131] Next, the operator inputs an operation to start replacing the bag covering the FPD 100 by operating an operation button (not shown) or the like. When the operation to start replacing the bag covering the FPD 100 is input, the package replacement device 1 moves the cutter of the bottom surface cutting mechanism 5 along the groove 105 provided on the bottom surface 103 of the FPD 100, similarly to the first embodiment, to cut the portion of the first bag 200 attached to the bottom surface 103. Then, the package replacement device 1 rotates the roller 3. As a result, the cutter of the side surface cutting mechanism 4 moves along the groove 104, thereby cutting the portion of the first bag 200 attached to the side surface 102.

[0132] In this embodiment, since the engaging portion 210 of the first bag 200 engages with the protruding portion 35 of the roller 3, when the FPD 100 is conveyed downward, the first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 is pulled by the roller 3. Then, the first bag 200 is peeled off from the FPD 100 and wound by each roller 3.

[0133] Similar to the first embodiment, the FPD 100 from which the first bag 200 has been peeled off is wrapped with the second bag 300 by the packaging mechanism 6 and taken out from the take-out port 8 .

[0134] Hereinafter, the effects of the package replacing device 1 according to the present embodiment will be described.

[0135] In the package replacement device 1 according to the present embodiment, the roller 3 includes a protrusion 35, and the first bag 200 includes an engagement portion 210 that can engage with the protrusion 35. By rotating the roller 3 with the engagement portion 210 engaged with the protrusion 35, the FPD 100 is conveyed and the first bag 200 peeled from the FPD 100 is wound around the roller 3.

[0136] According to the above structure, according to the package replacement device 1 of this embodiment, since the FPD 100 is conveyed in a state where the protrusion 35 is engaged with the engaging portion 210, the first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 is pulled by the roller 3 and peeled off from the FPD 100, and is respectively wound by the roller 3. Therefore, in this embodiment, as in the first embodiment, the first bag 200 can be automatically peeled off from the FPD 100. Thus, the infection prevention bag covering the X-ray detector can be automatically and easily replaced.

[0137] (Variation of the Second Embodiment)

[0138] Below, refer to Figures 13 to 18 , a modification example of the protrusion 35 provided on the roller 3 is described.

[0139] Fig.13 and Fig.14It is a figure which shows the structure of the roller 3 which concerns on a certain modification. Fig.13 This is a diagram of the roller 3 as viewed from one side in the Y-axis direction. Fig.14 3 is a diagram showing the roller 3 viewed from one side in the X-axis direction. Fig.13 and Fig.14 As shown, in this modification, a plurality of protrusions 35 are provided on each of the two end surfaces of the cylindrical portion 31. The protrusions 35 are respectively arranged at positions away from the shaft member 30. The protrusions 35 are arranged along the outer edge of the end surface of the cylindrical portion 31 at equal intervals.

[0140] Fig.15 and Fig.16 It is a figure which shows the structure of the roller 3 which concerns on another modification. Fig.15 This is a diagram of the roller 3 as viewed from one side in the Y-axis direction. Fig.16 3 is a diagram showing the roller 3 viewed from one side in the X-axis direction. Fig.15 and Fig.16 As shown, in this modification, a plurality of protrusions 35 are provided on the outer circumferential surface of the cylindrical portion 31 of the roller 3. The protrusions 35 are respectively arranged at both ends of the cylindrical portion 31, and protrude from the outer circumferential surface of the cylindrical portion 31 in a direction away from the shaft member 30. The protrusions 35 are respectively arranged at both ends of the cylindrical portion 31 at equal intervals along the circumferential direction of the cylindrical portion 31.

[0141] Fig.17 and Fig.18 It is a diagram showing the structure of the roller 3 according to another modified example. Fig.17 This is a diagram of the roller 3 as viewed from one side in the Y-axis direction. Fig.18 yes Fig.17 A-A line section view. Fig.17 and Fig.18 As shown, in this modification, a groove 37 that is recessed toward the shaft member 30 is provided on the outer peripheral surface of the cylindrical portion 31 of the roller 3. The groove 37 is extended along the X-axis direction of the roller 3.

[0142] Two protrusions 35 are provided inside the groove 37. Each of the protrusions 35 protrudes inwardly in the X-axis direction from a surface facing inwardly in the X-axis direction inside the groove 37.

[0143] Fig.19 and Fig. 20 It is a diagram showing the structure of the roller 3 according to another modified example. Fig.19 This is a diagram of the roller 3 as viewed from one side in the Y-axis direction. Fig. 20 yes Fig.19 The B-B line section view. Fig.19 and Fig. 20 As shown, in this modification, there are multiple Fig.17 and Fig.18The grooves 37 described above are respectively provided to extend in the X-axis direction. The grooves 37 are arranged at equal intervals along the circumferential direction of the cylindrical portion 31.

[0144] Two protrusions 35 are provided inside each groove 37. The protrusions 35 protrude inwardly in the X-axis direction from the surface facing inwardly in the X-axis direction inside the groove 37. The protrusions 35 are arranged at equal intervals along the circumferential direction of the cylindrical portion 31.

[0145] exist Figures 13 to 20 In the modified example shown, the engaging portions 210 are preferably provided in the same number as the total number of the protrusions 35 provided on the pair of rollers 3. By engaging the engaging portions 210 with the protrusions 35, respectively, the force with which the rollers 3 pull the first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 becomes larger, and the first bag 200 can be more reliably peeled off from the FPD 100.

[0146] In addition, Figures 17 to 20 In the modified example shown, a protrusion 35 is provided inside a groove 37 provided on the outer peripheral surface of the cylindrical portion 31. In this case, as in Figures 13 to 16 Compared with the case where the protrusion 35 protrudes outward from the outer peripheral surface of the cylindrical portion 31 as in the illustrated modification, the outer diameter of the roller 3 can be reduced.

[0147] (Third embodiment)

[0148] The third embodiment is described. This embodiment modifies the structure of the first embodiment as follows. The description of the same structure, operation and effect as the first embodiment is omitted. The packaging replacement device 1 of this embodiment is provided with a rotating pin 91 provided below the roller 3 to engage and peel off the first bag 200 mounted on the FPD 100 by rotating, instead of imparting adhesiveness to the roller 3.

[0149] Fig.21 and Fig. 22 It is a diagram showing the structure of the package replacing device 1 according to the present embodiment. Fig.21 This is a diagram showing the internal structure of the package replacing device 1 in a cross section perpendicular to the X-axis. Fig. 22 FIG. 1 is a diagram showing the internal structure of the packaging replacement device 1 as viewed from one side in the X-axis direction. Fig.21 and Fig. 22 As shown, the package replacement device 1 includes a pair of shaft members 90, a plurality of rotating pins 91, a plurality of first guides 92, a pair of recovery parts 93, and a pair of second guides 94. The rotating pins 91, the first guides 92, the recovery parts 93, and the second guides 94 are arranged inside the housing 2 below the roller 3 and above the packaging mechanism 6.

[0150] The shaft member 90 is disposed on the lower side of the roller 3. The shaft member 90 is a rod-shaped member extending parallel to the shaft member 30 of the roller 3. The shaft member 90 is rotatable relative to the housing 2.

[0151] A plurality of rotating pins 91 and a plurality of first guides 92 are alternately mounted on the shaft member 90. The first guides 92 are arranged at equal intervals along the X-axis direction. The rotating pins 91 are arranged between adjacent first guides 92. The rotating pins 91 are arranged at equal intervals along the X-axis direction.

[0152] As the shaft member 90 rotates relative to the housing 2, the rotating pins 91 rotate together with the shaft member 90 about the shaft member 90. The first guide portion 92 is attached to the shaft member 90 in a state where the rotation relative to the housing 2 is restricted and the first guide portion 92 is rotatable relative to the shaft member 90. Therefore, even if the shaft member 90 rotates relative to the housing 2, the first guide portion 92 does not rotate relative to the housing 2.

[0153] The rotating pins 91 each include a plurality of pins protruding in a direction away from the shaft member 90. The plurality of pins protrude at equal intervals about the circumferential direction centered on the shaft member 90. The pins are formed to have a length slightly smaller than the distance between the FPD 100 transported between the pair of shaft members 90 and the shaft member 90 in the Y-axis direction. That is, the pins are formed in a shape capable of hooking the first bag 200 covering the FPD 100 transported between the shaft members 90. The rotating pins 91 are formed of, for example, a resin material.

[0154] The first guides 92 are provided on the opposite side to the direction in which the FPD 100 is arranged so as to remove the first bag 200 hung on the pin of the rotating pin 91 from the rotating pin 91. Specifically, the shape and position of the first guides 92 are adjusted so as to contact the first bag 200 hung on the pin of the rotating pin 91 on the outer side of the shaft member 90 with respect to the Y-axis direction. The first guide 92 is, for example, an elliptical plate formed of a resin material.

[0155] The collecting portion 93 is disposed below the shaft member 90. The collecting portion 93 is a box that collects the first bag 200 removed from the rotating pin 91 by the first guide portion 92.

[0156] The second guide portion 94 is disposed between the roller 3 and the recovery portion 93. The second guide portion 94 is disposed outside the rotating pin 91 and the first guide portion 92 with respect to the Y-axis direction. The second guide portion 94 guides the first bag 200 hung on the rotating pin 91 and the first bag 200 removed from the rotating pin 91 by the first guide portion 92 to the recovery portion 93. The second guide portion 94 is, for example, a curved plate extending in the X-axis direction.

[0157] The package replacement device 1 includes a top surface cutting mechanism as a cutting mechanism in addition to the side surface cutting mechanism 4 and the bottom surface cutting mechanism 5. The top surface cutting mechanism cuts the portion of the first bag 200 attached to the top surface 101 of the FPD 100 after the first bag 200 is peeled off from the FPD 100.

[0158] The top surface cutting mechanism is installed inside the housing 2. The top surface cutting mechanism is connected to a driving device such as a motor, and is driven by the driving device to move along the X-axis. The top surface cutting mechanism cuts the portion of the first bag 200 covering the FPD 100 that is mounted on the top surface 101 of the FPD 100 by moving relative to the housing 2 along the X-axis.

[0159] The top surface cutting mechanism is realized by, for example, the same structure as the bottom surface cutting mechanism 5. For example, the top surface cutting mechanism is composed of a rail fixed to the inner wall of the housing 2 and an L-shaped arm movable on the rail and having a downwardly facing cutter at the front end.

[0160] Alternatively, the portion of the first bag 200 mounted on the top surface 101 of the FPD 100 may be cut by the top surface cutting mechanism while the roller 3 is pausing the rotation of the roller 3 while the FPD 100 is being conveyed downward. In this case, a groove through which the cutter of the top surface cutting mechanism passes is formed on the top surface 101 of the FPD 100 over the entire width direction.

[0161] Next, refer to Fig.23 The operation of the package replacing device 1 according to the present embodiment will be described.

[0162] When replacing the first bag 200 covering the FPD 100 with the second bag 300 using the package replacement device 1 , the operator first inserts the FPD 100 covered by the first bag 200 between the pair of rollers 3 and fixes the FPD 100 between the rollers 3 .

[0163] Next, the operator inputs an operation to start replacing the bag covering the FPD 100 by operating an operation button (not shown) or the like. When the operation to start replacing the bag covering the FPD 100 is input, the package replacement device 1 cuts the portion of the first bag 200 attached to the bottom surface 103 by moving the cutter of the bottom surface cutting mechanism 5 along the groove 105 provided on the bottom surface 103 of the FPD 100, as in the first embodiment. Then, the package replacement device 1 rotates the roller 3. As a result, the cutter of the side surface cutting mechanism 4 moves along the groove 104, and the portion of the first bag 200 attached to the side surface 102 is cut. Fig.23 This is a diagram showing a state where the FPD 100 wrapped in the first bag 200 is conveyed by the rollers 3 .

[0164] In this embodiment, the package replacement device 1 rotates the roller 3 and rotates the shaft member 90 in the opposite direction to the roller 3. As a result, while the FPD 100 is conveyed downward, the first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 is caught by the pin of the rotating pin 91. Then, the first bag 200 is caught by the pin of the rotating pin 91 and the first bag 200 is peeled off from the FPD 100. As in the first embodiment, the FPD 100 from which the first bag 200 has been peeled off is wrapped with the second bag 300 by the packaging mechanism 6 and taken out from the take-out port 8.

[0165] The first bag 200 peeled off from the FPD 100 by the rotating pin 91 has its portion mounted on the top surface 101 of the FPD 100 cut by the top surface cutting mechanism. The first bag 200 peeled off from the FPD 100 is conveyed outwardly in the Y-axis direction by the rotation of the rotating pin 91, and contacts the first guide portion 92 outside the shaft member 90. Then, the first bag 200 contacts the first guide portion 92 and is removed from the pin of the rotating pin 91. The first bag 200 removed from the pin of the rotating pin 91 is guided to the inside of the recovery portion 93 by the second guide portion 94, and is recovered by the recovery portion 93.

[0166] Hereinafter, the effects of the package replacing device 1 according to the present embodiment will be described.

[0167] The package replacing device 1 according to the present embodiment includes a rotating pin 91 for peeling off the first bag 200 attached to the FPD 100 , and a collecting unit 93 for collecting the first bag 200 caught on the rotating pin 91 .

[0168] According to the above structure, according to the package replacement device 1 related to this embodiment, the first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 is peeled off from the FPD 100 by the rotating pin 91. And the first bag 200 peeled off from the FPD 100 by the rotating pin 91 is recovered in the recovery part 93. Therefore, in this embodiment, as in the first embodiment, the first bag 200 can be automatically peeled off from the FPD 100. Thus, the bag for preventing infection covering the X-ray detector can be automatically and easily replaced.

[0169] Furthermore, the package replacing device 1 according to the present embodiment further includes a top surface cutting mechanism for cutting a portion of the first bag 200 mounted on the top surface 101 of the FPD 100 by moving in the width direction of the FPD 100 .

[0170] According to the above structure, according to the package replacement device 1 of the present embodiment, by further cutting the first bag 200 cut by the side cutting mechanism 4 and the bottom cutting mechanism 5 with the top cutting mechanism, all the parts of the first bag 200 can be recovered in the recovery unit 93. Therefore, instead of recovering the first bag 200 peeled off from the FPD 100 every time the bag of the FPD 100 is replaced, the bags of a plurality of FPDs 100 can be replaced continuously. As a result, the replacement operation of the anti-infection bag covering the FPD 100 becomes easier.

[0171] (Variation of the third embodiment)

[0172] In order to effectively store the first bag 200 conveyed to the recovery section 93, a folding mechanism that automatically folds the first bag 200 may also be provided at the recovery section 93. The folding mechanism is realized, for example, by a plate-like member that rotates inside the recovery section 93. In this case, the plate-like member is arranged near the outer wall surface of the recovery section 93 with respect to the Y-axis direction. The plate-like member is connected to the bottom surface of the recovery section 93 with one side parallel to the Y-axis direction, and rotates relative to the recovery section 93 with the connection portion with the recovery section 93 as the center. The plate-like member rotates inside the recovery section 93, and repeatedly performs the action of falling inward with respect to the Y-axis direction from a state of being erected roughly parallel to the outer wall surface of the recovery section 93 and the action of standing up from the fallen state. And, by repeatedly performing the above-mentioned action in a certain cycle when the first bag 200 is conveyed to the recovery section 93, the conveyed first bag 200 can be automatically folded one by one.

[0173] The folding mechanism may be realized by a U-shaped rod-shaped member whose both ends are rotatably connected to the bottom surface of the collecting portion 93 instead of the above-mentioned plate-shaped member.

[0174] (Fourth embodiment)

[0175] A fourth embodiment will be described. In this embodiment, the structure of the first embodiment is modified as follows. The description of the same structure, operation, and effect as those of the first embodiment will be omitted.

[0176] Fig.24: is a diagram showing the structure of the packaging replacement device 1 of the present embodiment. The packaging replacement device 1 related to the present embodiment replaces the packaging covering the ultrasonic probe 400 that is wirelessly connected to the ultrasonic diagnostic device. Specifically, the packaging replacement device 1 is a device that peels off the first bag 500 from the ultrasonic probe 400 covered by the first bag 500 and automatically covers the ultrasonic probe 400 with the second bag 600 (not shown). The first bag 500 and the second bag 600 are, for example, sterilized covers that cover the ultrasonic probe 400 to prevent infection during ultrasonic examinations of patients with infectious diseases such as COVID-19.

[0177] The ultrasonic probe 400 includes an ultrasonic transducer for generating ultrasonic waves and a transceiver for transmitting and receiving ultrasonic waves to and from a subject. The ultrasonic probe 400 has a structure capable of wirelessly transmitting data generated by transmitting and receiving ultrasonic waves to and from a subject to a main body of the ultrasonic diagnostic apparatus.

[0178] The ultrasonic probe 400 includes a front end face 401 provided with an ultrasonic wave transmitting and receiving unit and a bottom face 402 provided at an end portion opposite to the front end face 401. In addition, the ultrasonic probe 400 includes a front face 403 provided with a display unit and the like and a back face 404 facing the side opposite to the front face 403. The front face 403 and the back face 404 are provided parallel to each other along the central axis of the ultrasonic probe 400. That is, the ultrasonic probe 400 has a certain thickness.

[0179] In addition, the ultrasonic probe 400 includes a front end face 401, a bottom face 402, and two side faces 405 facing in a direction intersecting the front face 403 and the back face 404. The side faces 405 have a curved surface in a portion. Here, a direction perpendicular to the central axis of the ultrasonic probe 400 and parallel to the front face 403 and the back face 404 is defined as a width direction of the ultrasonic probe 400. The width W of the ultrasonic probe 400 is the distance between the two side faces 405. The width W of the ultrasonic probe 400 changes depending on the position in the direction along the central axis. The width W of the ultrasonic probe 400 gradually increases from the portion held by the user toward the front end side, and then gradually decreases at the front end.

[0180] In addition, similarly to the first embodiment, grooves into which the side surface cutting mechanism 4 or the bottom surface cutting mechanism 5 is inserted are formed on the side surface 405 and the bottom surface 402 of the ultrasonic probe 400 .

[0181] The ultrasonic probe 400 covered by the first bag 500 is inserted into the insertion port of the package replacement device 1 with the central axis aligned with the plumb bob. Here, the case where the ultrasonic probe 400 is inserted into the insertion port with the front end 401 facing downward is described, but the package replacement device 1 may be configured so that the ultrasonic probe 400 is inserted with the front end 401 facing upward.

[0182] The package replacement device 1 is similar to the first embodiment, and includes a housing 2, a pair of rollers 3, a side cutting mechanism 4 (not shown), a packaging mechanism 6 (not shown), and a removal port 8. In addition, the package replacement device 1 includes a front end surface cutting mechanism (not shown) for cutting the portion of the first bag 500 mounted on the front end surface of the ultrasonic probe 400 instead of the bottom surface cutting mechanism 5. The front end surface cutting mechanism has, for example, the same structure as the bottom surface cutting mechanism 5. The front end surface cutting mechanism is equivalent to the cutting mechanism. The pair of rollers 3 is equivalent to the peeling mechanism.

[0183] The arrangement and shape of the housing 2, the pair of rollers 3, the side cutting mechanism 4, the front end surface cutting mechanism, the packaging mechanism 6, and the removal port 8 are appropriately adjusted according to the size and shape of the ultrasonic probe 400. For example, the distance between the pair of rollers 3 provided as the insertion port and the conveying mechanism is set to a distance slightly larger than the thickness of the ultrasonic probe 400 in order to hold and convey the inserted ultrasonic probe 400.

[0184] According to the above structure, according to the packaging replacement device 1 related to this embodiment, the peeling mechanism peels the first bag 500 from the ultrasonic probe 400, and the packaging mechanism covers the ultrasonic probe 400 with the second bag 600, thereby making it possible to easily replace the anti-infection bag covering the ultrasonic probe 400.

[0185] In addition, in Fig.24 When the width of the ultrasonic probe 400 is not constant in the direction along the central axis, such as the ultrasonic probe 400 shown in FIG. 1 , it is preferable to apply force to the inside of the cutter of the side cutting mechanism 4 from the inner wall of the housing 2. For example, the inner wall of the housing 2 and the cutter are connected by a spring. In this case, the cutter moves inside the groove provided on the side surface 405 while being applied inward by the spring, so that even if a curved surface is provided on the side surface 405, the portion of the first bag 500 mounted on the side surface 405 of the ultrasonic probe 400 can be cut. In this way, even for medical equipment such as the ultrasonic probe 400 whose width is not constant, the bag for preventing infection covering the ultrasonic probe 400 can be easily replaced.

[0186] In the present embodiment, the case where the packaging of the ultrasonic probe 400 having a constant thickness is replaced is described, but it can also be applied to the case where the packaging of the ultrasonic probe 400 having a non-constant thickness in the direction along the central axis is replaced. In this case, for example, one of the pair of rollers 3 is forced in the direction toward the other roller. Thus, force is applied to reduce the distance between the pair of rollers 3. In the force applied by the rollers 3, for example, an elastic member such as a spring is used. When the ultrasonic probe 400 inserted between the pair of rollers 3 is transported, the position of the roller 3 to which the force is applied moves in accordance with the change in the thickness of the inserted ultrasonic probe 400, and the distance between the pair of rollers 3 changes. Thus, for the ultrasonic probe 400 having a non-constant thickness, the pair of rollers 3 also effectively functions as a transport mechanism.

[0187] (Variations of the first to fourth embodiments)

[0188] Here, as an example, a case where the package of the FPD 100 is replaced as in the first to third embodiments is described, but the same structure can also be applied when the package of the ultrasonic probe 400 is replaced as in the fourth embodiment.

[0189] A fragile portion having a strength lower than that of other portions may be provided on the portion to be cut in the bag covering the FPD 100. The fragile portion is provided on the portion mounted on the side surface 102 and the portion mounted on the bottom surface 103 in the bag covering the FPD 100. The fragile portion is realized, for example, by making the thickness of the bag thinner than that of other portions. Alternatively, the fragile portion is realized by providing a sewing thread. When such a fragile portion is provided, the first bag 200 is automatically cut at the fragile portion by the force applied by the roller 3 and the rotating pin 91 to pull the first bag 200 to both sides when the FPD 100 covered by the first bag 200 is conveyed by the roller 3. Therefore, when a fragile portion is provided on the bag covering the FPD 100, the side cutting mechanism 4, the bottom cutting mechanism 5, the top cutting mechanism, and the grooves 104 and 105 of the FPD 100 may also be omitted.

[0190] The second bag 300 may also be produced by a heat shrinkable sheet that shrinks by being applied with heat. In this case, the packaging mechanism 6 generates the second bag 300 covering the FPD100 by applying heat to the heat shrinkable sheet after the FPD100 from which the first bag 200 has been peeled is covered with a heat shrinkable sheet. Specifically, first, a folded heat shrinkable sheet is set in the packaging mechanism 6. If the FPD100 from which the first bag 200 has been peeled is arranged on the heat shrinkable sheet, hot air is blown to the heat shrinkable sheet after the FPD100 is covered with the heat shrinkable sheet. The heat shrinkable sheet covering the FPD100 shrinks by being blown with hot air, and the second bag 300 is produced in a manner of covering the FPD100. In this case, the FPD100 can be covered with the second bag 300 so that air does not enter between the second bag 300 and the FPD100. Furthermore, since air does not enter between the second bag 300 and the FPD 100 , the FPD 100 is easy to hold, and the FPD 100 is less likely to slip when held.

[0191] Alternatively, a roll on which the heat shrink sheet is wound may be fixed inside the housing 2. In this case, each time the bag for one X-ray detector is replaced, a new heat shrink sheet is supplied from the roll to the packaging mechanism 6. The roll is an example of a supply mechanism.

[0192] Furthermore, the heat shrink sheet may be automatically supplied from the drum in response to the opening of the take-out port 8. Furthermore, the heat shrink sheet may be automatically supplied based on the detection of the taking-out of the FPD 100 from the take-out port 8.

[0193] In addition, the package replacement device 1 may be configured to replace only the outer bag of the double bag covering the FPD 100. In this case, for example, a weak portion with relatively low strength is provided only on the outer bag, and only the outer bag is peeled off from the FPD 100 by pulling with the adhesive roller 3. Alternatively, a partition plate that prevents the side cutting mechanism 4 and the bottom cutting mechanism 5 from cutting the inner bag is inserted between the double bags covering the FPD 100, and only the outer bag is cut by the side cutting mechanism 4 and the bottom cutting mechanism 5.

[0194] In addition, in the embodiments described so far, an example in which a groove is formed on the side of the FPD is described, but it can also be implemented by a normal FPD in which a groove is not formed on the side. In this case, an accessory that is detachably arranged on the side of the FPD and has a groove formed on the outside can be used. For example, the FPD is packaged in a plastic bag in a state where the accessory is installed on the side of the FPD. The FPD packaged in the plastic bag is inserted into the packaging replacement device 1 and transported. When the FPD is transported in the packaging replacement device 1, the groove formed on the accessory is set to abut against the cutter on the side cutting mechanism 4 or the bottom cutting mechanism 5 of the packaging replacement device 1. When the packaging replacement device 1 and the FPD constructed in this way are inserted into the packaging replacement device 1 and transported, the cutter of the cutting mechanism abuts against the groove formed on the accessory. As a result, the plastic bag packaging the FPD between the cutter and the groove is cut. In addition, the accessory can also be used in the case of packaging the FPD with two plastic bags. For example, the accessory is installed while the first plastic bag is wrapped on the FPD, and then the second plastic bag is wrapped on the FPD. That is, in this case, since the accessory is installed from above the plastic bag wrapping the FPD, the cutter does not come into contact with the first (inner) plastic bag through the accessory, and only the second (outer) plastic bag is cut by the cutter. In this way, the old plastic bag can be replaced with a new one without exposing the detection surface of the FPD.

[0195] In the first to fourth embodiments, the case where a pair of rollers 3 is used as a conveying mechanism is described, but the present invention is not limited thereto. For example, a track extending in the up-down direction on the inner wall of the housing 2 and a holding member capable of moving up-down on the track while holding the FPD 100 inserted from the insertion port may be provided instead of the pair of rollers 3. In this case, the track and the holding member function as a conveying mechanism. In addition, as long as the structure holds a portable medical device such as the FPD 100 or the ultrasonic probe 400 and can be conveyed in the up-down direction, the conveying mechanism may be realized by a structure other than the above.

[0196] According to at least one embodiment described above, it is possible to easily replace an infection prevention bag covering a medical device.

[0197] Several embodiments of the present invention have been described, but these embodiments are provided as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the scope of the invention. These embodiments and their variations are included in the scope or spirit of the invention, and are included in the invention described in the claims and the scope of their equivalents.
