Description

Technical Field

[0001] The invention relates to the field of radioactive contamination cleaning and decontamination, and in particular to a wrapping bag used for cleaning radioactive contamination of human extremities. Background Art

[0002] There is a risk of contamination by radionuclides in relevant nuclear-related sites such as hospital nuclear medicine departments, nuclear industrial postprocessing sites, irradiation centers, and personnel involved in nuclear accidents. Currently, the commonly used methods for decontamination of radionuclides are full-body showers or local cleaning.

[0003] For local contamination of the human body surface, the commonly used disinfection methods are wiping method and local flushing method. Among them, the commonly used disinfection device for the local flushing method is to fix the disinfection nozzle and brush at the front end of the disinfection handle, and clean the local nuclear contamination by brushing. However, during the brushing process, this method is likely to cause the nuclear contaminated water after flushing to flow out of the gap between the brushes and flow to other parts that are not contaminated by radioactivity, causing radionuclide contamination or even infection in other parts. In particular, the surface of the limbs (such as the gaps between fingers) cannot form a completely enclosed space with the brush, which makes it easier for the nuclear contaminated water after flushing to be unable to be effectively recovered, resulting in radionuclide contamination or even infection in other parts.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] First, to facilitate understanding of the embodiments of the present invention, some terms or nouns involved in the present invention are explained below:

[0030] The human extremities refer to the end parts of the limbs, including fingers, toes, palms, soles of feet, etc. Their main function is to complete various movements and functions of the hands and feet.

[0031] Ductility and ductility are mechanical properties of a material, which indicate its ability to deform plastically before it breaks under stress.

[0032] The universal joint shaft (universal coupling) utilizes the characteristics of its mechanism to enable the two connected shafts to rotate continuously and reliably transmit torque and motion when the two shafts are not on the same axis and there is an angle between the axes.

[0033] like Figures 1 to 4 As shown, an embodiment of the present invention provides a wrapping bag for cleaning radioactive contamination of human extremities.

[0034] Figure 1 An overall diagram of a wrapping bag for cleaning radioactive contamination of human extremities provided by an embodiment of the present invention, such as Figure 1 As shown, the wrapping bag provided by the present embodiment includes: a disinfection device interface 101, used to connect the disinfection device; a nozzle 102, installed at the disinfection device interface 101, connected to the disinfection device, and used to spray the water source connected to the disinfection device; a flexible wrapping bag body 201, connected to the disinfection device, using a stretchable and shrinkable material to seal the disinfection device, and provided with an opening for placing a human extremity, the opening being the end away from the disinfection device; a wrapping bag mouthpiece 202, arranged on one side of the opening, used to tighten the opening to form an enclosed space after a human extremity is placed in the flexible wrapping bag body 201.

[0035] Based on the above connection relationship, the human extremity is placed through the opening into the flexible wrapping bag body 201, so that the human extremity completely blocks the opening, and the decontamination device, the human extremity and the flexible wrapping bag body 201 form a closed whole. After the decontamination device is started, the human extremity is rinsed, and the nuclear contaminated water after rinsing remains in the closed space formed by the decontamination device, the human extremity and the flexible wrapping bag body 201. Since the nuclear contaminated water has been contaminated by radionuclides, the human extremity has been in the closed space and may be exposed to the nuclear contaminated water after rinsing, so the recovery device 3 is set on the flexible wrapping bag body 201, so that the decontamination device, the flexible wrapping bag body 201, the human extremity and the recovery device 3 form a closed whole.

[0036] Optionally, one end of the recovery device 3 extends into the flexible wrapping bag body 201, and the other end is connected to a recovery device similar to the recovery box 302, so that the nuclear contaminated water retained in the flexible wrapping bag body 201 flows into the recovery device 3, and will not re-contaminate the human extremities after flushing. It should be noted that the human extremities are limbs such as hands and feet. By flushing, the radioactive contaminants in the gaps between fingers or the grooves of toes can be completely removed, effectively achieving better removal of contamination, thereby better ensuring the health of the human body.

[0037] By adopting the above technical solution, the decontamination device is enclosed by the flexible wrapping bag body 201. After the human extremities are placed in the flexible wrapping bag body 201 through the opening, the nuclear contaminated water used by the decontamination device to wash the human extremities will not flow to the outside of the flexible wrapping bag body 201, effectively preventing the nuclear contaminated water from flowing to the parts not contaminated by radioactivity and being contaminated by the nuclides. A recovery device 3 is set to recover the nuclear contaminated water, effectively realizing the recovery of the used nuclear contaminated water and preventing it from flowing out of the flexible wrapping bag body 201. Thus, the technical effect of effectively recovering the used nuclear contaminated water and preventing the parts not contaminated by radioactivity from being contaminated by nuclides is achieved.

[0038] like Figure 1 As shown, the flexible wrapping bag body 201 includes: a flexible wrapping bag body 201, which is connected to the disinfection device, made of stretchable and shrinkable material, and an opening is set at the end away from the disinfection device; a wrapping bag mouth tightener 202, which is set on one side of the opening and is used to tighten the opening to form a closed space after the human body extremity is placed in the flexible wrapping bag body 201.

[0039] With the above structure, the stretchable and shrinkable material can be directly selected from materials such as silicone, polyurethane or homopolymer of vinyl chloride (PVC) to construct the entire flexible wrapping bag body 201, or hard plastic can be used to make the bottom of the flexible wrapping bag body 201 (wherein the bottom is the end connected to the disinfection device), and flexible material can be used to make the top of the flexible wrapping bag body 201 (wherein the top is the opening), so that the bottom and the top are connected by high-temperature fusion to form an enclosed space.

[0040] In addition, one end of the flexible wrapping bag body 201 connected to the disinfection device can be set to a foldable structure, that is, a column composed of multiple parts of hard plastic material to form multiple cylinders, and the multiple columns are connected by flexible material, so that the flexible wrapping bag body 201 can be folded at the flexible material. The folded flexible wrapping bag body 201 is easy to store, which effectively achieves the effect of easy carrying.

[0041] Optionally, the wrapping bag mouth tightener 202 is used to tighten the opening of the flexible wrapping bag body 201, that is, after the human body's limbs are inserted into the flexible wrapping bag body 201, there may be a gap between the opening and the human body's limbs. If there is a gap here, nuclear contaminated water after flushing by the disinfection device may flow out from the gap and contaminate other parts that are not contaminated by radioactivity. Therefore, the opening needs to be completely tightened by the wrapping bag mouth tightener 202, that is, the opening completely fits the human body's limbs without leaving any gaps, thereby effectively avoiding the effect of radioactive contamination of parts that are not contaminated by radioactivity.

[0042] By adopting the above technical solution, a flexible wrapping bag body 201 that can be stretched and contracted is used, so that the human extremities can be effectively placed in the flexible wrapping bag body 201, and the opening between the flexible wrapping bag body 201 and the human extremities can be tightened by the wrapping bag mouth tightener 202, so that the flexible wrapping bag body 201 and the human extremities form a closed space, effectively preventing nuclear contaminated water from flowing out of the flexible wrapping bag body 201, thereby effectively preventing the parts that are not contaminated by radioactivity from being contaminated by nuclides.

[0043] like Figure 1 As shown, the wrapping bag mouth drawer 202 includes: a pull-out elastic rope 2021, including a movable end and a fixed end, the fixed end is fixedly connected to the flexible wrapping bag body 201, and the movable end is connected to the flexible wrapping bag body 201 after being stretched away from the fixed end; Velcro 2022, including a fixed sheet and an adhesive sheet, the fixed sheet is installed near the opening of the flexible wrapping bag body 201, and is arranged in the moving direction of the movable end of the pull-out elastic rope 2021; the adhesive sheet is fixedly arranged on the movable end of the pull-out elastic rope 2021.

[0044] With the above structure, the wrapping bag mouth cinch 202 can adopt a variety of cinch methods, one of which may be tightened by an elastic cord. One end of the pull-out elastic cord 2021 is fixed to the open end of the flexible wrapping bag body 201, which can be fused at high temperature or sewn. The other end of the pull-out elastic cord 2021 can be moved, and after the pull-out elastic cord 2021 is tightened, the mobile end is fixed to the flexible wrapping bag body 201. The mobile end and the flexible wrapping bag body 201 can be fixed by the sticking method of Velcro 2022. That is, the above tightening method is similar to the pulling and tightening method at the cuffs of a winter coat, which is used to tighten the opening at the connection with the human body's limbs. The opening of the flexible wrapping bag body 201 is effectively tightened to prevent nuclear contaminated water from flowing out to the outside of the flexible wrapping bag body 201.

[0045] By adopting the above-mentioned technical scheme, the movable end of the pull-out elastic rope 2021 is stretched to a state where the opening at the human body's limb is tightened, so that the adhesive sheet at the movable end is adhered to the fixed sheet of the flexible wrapping bag body 201, thereby effectively tightening the opening of the flexible wrapping bag body 201 and preventing nuclear contaminated water from flowing out of the flexible wrapping bag body 201, thereby effectively preventing the parts that are not contaminated by radioactivity from being contaminated by nuclides.

[0046] like Figure 2 As shown, Figure 2A structural diagram of an air column bag 203 of a wrapping bag for cleaning radioactive contamination of human extremities provided in an embodiment of the present invention, wherein a wrapping bag mouth restrainer 202 comprises: an air column bag 203, installed at the opening, adopting a retractable sealed bag, with an inflation port, which expands until the opening is tightened after inflation; an air pump 204, connected to the inflation port, for inflating air into the air column bag 203.

[0047] With the above structure, the wrapping bag mouth-tightening device 202 can adopt a variety of tightening methods, and may also use the method of tightening after inflating the air column bag 203. The air column bag 203 can use a retractable closed air bag, for example, a long balloon, the port of the balloon is the inflation port, the long balloon is connected to the edge of the opening, and the air column bag 203 is expanded by inflating the air column bag 203, so that the caliber of the opening gradually becomes smaller, so as to fit closely with the human body extremity. That is, the above tightening method is similar to an instrument for measuring blood pressure, which is placed on the upper arm of the limb and gradually tightened on the upper arm after inflation. The opening of the flexible wrapping bag body 201 is effectively tightened to prevent nuclear contaminated water from flowing out to the outside of the flexible wrapping bag body 201.

[0048] By adopting the above-mentioned technical scheme, the wrapping bag mouth tightener 202 can also adopt a closed air column bag 203, which is installed at the opening. After the human body's limbs pass through the opening and penetrate into the flexible wrapping bag body 201, the air pump 204 inflates the air column bag 203 to make the air column bag 203 expand until it expands to be in close contact with the human body's limbs, thereby effectively tightening the opening of the flexible wrapping bag body 201 and preventing nuclear contaminated water from flowing out of the flexible wrapping bag body 201, thereby effectively preventing the parts that are not contaminated by radioactivity from being contaminated by nuclides.

[0049] like Figure 2 As shown, the wrapping bag mouth tightener 202 also includes: a pressure gauge 205, which is connected to the air column bag 203 and communicates with the air pump 204. When the pressure gauge 205 reaches a preset pressure value, the air pump 204 stops inflating the air column bag 203.

[0050] With the above structure, since the air is inflated into the air column bag 203 by the air pump 204, it is necessary to control the amount of air inflated into the air column bag 203 by the air pump 204. When the air pressure of the air column bag 203 is too high, it is easy to cause the air column bag 203 to burst (similar to a balloon being blown up) or cause the human body's limbs to be over-tightened. When the human body's limbs are over-tightened, the blood circulation in the limbs will be blocked. When the flushing time period is too long, it may cause the limb blood vessels to be compressed, thereby causing problems with the limbs, so it is necessary to control the air pressure in the air column bag 203.

[0051] Optionally, the pressure in the air column bag 203 is detected by a pressure gauge 205. When the pressure value exceeds a preset pressure value, the air pump 204 stops inflating the air column bag 203. It should be noted that the preset pressure value can be set according to actual conditions. As each person's limbs are of different thicknesses, the pressure value can be set according to the actual person, thereby effectively avoiding the bursting of the air column bag 203 and keeping the extremities of the human body in a tightened but discomfort-free state.

[0052] like Figure 3 As shown, Figure 3 A structural diagram of a recovery device 3 for a wrapping bag used for cleaning radioactive contamination of human extremities provided in an embodiment of the present invention. The recovery device 3 is arranged in a sealed space formed by a cleaning device and a flexible wrapping bag body 201, and is used to recover nuclear contaminated water after flushing.

[0053] Using the above structure, the recovery device 3 includes: a reflux channel 301, one end of which is connected to the flexible wrapping bag body 201, extending through the flexible wrapping bag body 201, and is used to recover the nuclear contaminated water after flushing; a recovery box 302, which is connected to the reflux channel 301 and is used to collect the nuclear contaminated water recovered by the reflux channel 301.

[0054] The reflux channel 301 is set at the bottom of the flexible wrapping bag body 201, that is, the part of the flexible wrapping bag body 201 closest to the ground. By using the reflux channel 301, due to the characteristic of water flowing to lower places, the flushed nuclear contaminated water is returned to the collection box, thereby effectively realizing the recovery of the nuclear contaminated water.

[0055] like Figure 3 As shown, the recovery device 3 also includes: an air pump 206 connected to the flexible wrapping bag body 201 , extending through the flexible wrapping bag body 201 , and used to inflate the flexible wrapping bag body 201 to support the flexible wrapping bag body 201 .

[0056] With the above structure, if the connection between the reflux channel 301 and the flexible wrapping bag body 201 is not at the part of the flexible wrapping bag body 201 closest to the ground, for example, the reflux channel 301 is set near the decontamination device, that is, the reflux channel 301 is installed on the side of the water spray pipe 101 of the decontamination device, parallel to the water spray pipe 101, so that the flexible wrapping bag body 201 has only one opening and a connection port with the decontamination device, which effectively reduces the probability of water leakage of the flexible wrapping bag body 201. However, in this case, since the nuclear contaminated water cannot flow into the reflux channel 301 by itself, it is necessary to set an air pump 206 to inflate the flexible wrapping bag body 201 so that the flexible wrapping bag body 201 is pressurized, that is, the nuclear contaminated water is pressed into the reflux channel 301 by air pressure, which effectively achieves the effect of recycling the nuclear contaminated water.

[0057] By adopting the above technical solution, when there are wrinkles in the flexible wrapping bag body 201, part of the nuclear contaminated water is retained in the wrinkles and cannot be recovered into the recovery box 302. At this time, the air pump 206 is started to inflate the flexible wrapping bag body 201, and the wrinkles in the flexible wrapping bag body 201 are flattened by the gas, and the enclosed space of the flexible wrapping bag body 201 is pressurized, and the nuclear contaminated water is pressed into the reflux channel 301, thereby effectively achieving the recovery effect of the nuclear contaminated water.

[0058] like Figure 3 As shown, the recovery device 3 also includes: a filter 303, including multiple isolation plates, installed at the connection between the reflux channel 301 and the flexible wrapping bag body 201; the multiple isolation plates are respectively provided with filter holes, and the multiple isolation plates can rotate relative to each other to adjust the overlapping area of ​​the filter holes.

[0059] With the above structure, during the process of flushing the human extremities, there may be solid soil or other substances on the human extremities. Since the treatment methods for nuclear contaminated water and solid dirt are different, a filter 303 is set at the reflux channel 301 to block the solid dirt and separate the solid dirt from the nuclear contaminated water, thereby effectively recovering the nuclear pollutants and treating them separately.

[0060] Optionally, the filter 303 is provided with a plurality of isolation plates, and the plurality of isolation plates can rotate relative to each other and rotate at different angles, so that the overlapping area of ​​the filter holes changes, thereby achieving the effect of isolating a plurality of substances.

[0061] like Figure 3 As shown, the recovery device 3 also includes: a negative pressure pump 207 connected to the recovery box 302, used to suck out the gas in the recovery box 302 to form a negative pressure in the recovery box 302.

[0062] With the above structure, a negative pressure pump 207 is provided at the recovery box 302 for sucking out the gas in the recovery box 302 so that negative pressure is formed in the recovery box 302. When part of the nuclear contaminated water in the flexible wrapping bag body 201 cannot flow into the recovery box 302, the nuclear contaminated water automatically flows into the recovery box 302 based on the negative pressure of the recovery box 302.

[0063] like Figure 1 As shown, the disinfection device includes: a water spray pipe 101, one end of which is connected to a water source, and the other end extends through the flexible wrapping bag body 201 to spray water into the flexible wrapping bag body 201; a nozzle 102, which is installed on the water spray pipe 101 and is located at one end of the water spray pipe 101 located in the flexible wrapping bag body 201.

[0064] By adopting the above technical solution, the nozzle 102 uses the water source transmitted by the water spray pipe 101 to spray water into the flexible wrapping bag body 201, thereby cleaning the human extremities in the flexible wrapping bag body 201, effectively achieving local nuclear contamination treatment of the human extremities.

[0065] like Figure 4 As shown, Figure 4 The present invention provides a screw cap structure diagram of a wrapping bag for cleaning radioactive contamination of human extremities provided in an embodiment of the present invention. The wrapping bag also includes: a screw cap 103 rotatably connected to the nozzle 102 for rotating and adjusting the spray pressure of the nozzle 102 .

[0066] With the above structure, a plurality of spray holes are arranged on the spray head 102, and the spray holes spray water outward like a shower. However, since there may be some substances on the human extremities that are difficult to wash, it is necessary to use a flushing method with partial pressure to wash away the radioactive contaminated substances on the human extremities. Therefore, a screw cap 103 is arranged at the end of the spray head 102, and the screw cap 103 is rotatably connected to the spray head 102 through a threaded nut connection method (the spray head 102 is provided with a positive thread, and the screw cap 103 is equivalent to a nut, and has a reverse thread matching the positive thread of the spray head 102). The tighter the connection between the screw cap 103 and the spray head 102 is, the greater the pressure of the spray hole at the spray head 102 is covered. At this time, the water sprayed has a greater water pressure, which can effectively achieve the washing away of some substances on the human extremities that are difficult to wash.

[0067] By adopting the above technical solution, the nozzle 102 can spray water into the flexible wrapping bag body 201. However, since there may be solid mud or other substances in some human extremities, a certain water pressure is required to flush them away. At this time, by rotating the screw cap 103, the water outlet of the nozzle 102 is pressed tightly, so that the water sprayed from the nozzle 102 has a certain pressure, thereby flushing away the solid mud or other substances, effectively realizing the treatment of local nuclear contamination of the human extremities.

[0068] like Figure 4 As shown, the wrapping bag also includes: a universal connecting shaft 104, which is arranged between the water spraying pipe 101 and the spray head 102, and is used to adjust the rotation direction of the spray head 102.

[0069] With the above structure, the universal connecting shaft 104 is a spherical rotatable shaft, including a fixed ball socket and a universal ball rotatable in the ball socket. The reflux channel 301 passes through the ball socket and is connected to the universal ball, and passes through the end of the universal ball to connect to the nozzle 102, thereby effectively realizing that the nozzle 102 can spray flushing water in different directions as the universal ball rotates in the ball socket.

[0070] By adopting the above technical solution, a universal connecting shaft 104 is set at the connection between the water spray pipe 101 and the nozzle 102, so that the nozzle 102 can rotate, effectively realizing the flushing of multiple directions of the human extremities, thereby achieving cleaner local nuclear contamination treatment of the human extremities.

[0071] The device provided by the embodiment has the following beneficial effects:

[0072] (1) The purpose of isolating the nuclear contaminated water after flushing to prevent it from flowing out to the parts not contaminated by radioactivity and recovering the nuclear contaminated water is achieved, thereby achieving the technical effect of effectively recovering the nuclear contaminated water after use and preventing the parts not contaminated by radioactivity from being contaminated by radionuclides, thereby solving the technical problem of the parts not contaminated by radioactivity being contaminated by radionuclides due to the inability to effectively recover the nuclear contaminated water after use.

[0073] (2) One end of the flexible wrapping bag body 201 connected to the disinfection device can be set to a foldable structure, that is, a column composed of multiple parts of hard plastic material to form multiple cylinders, and the multiple columns are connected by flexible material, so that the flexible wrapping bag body 201 can be folded at the flexible material. The folded flexible wrapping bag body 201 is easy to store, which effectively achieves the effect of easy carrying.

[0074] (3) During the flushing process of human extremities, there may be solid soil or other substances on the extremities. Since the treatment methods for nuclear contaminated water and solid dirt are different, a filter 303 is set at the reflux channel 301 to block the solid dirt and separate the solid dirt from the nuclear contaminated water, thereby effectively recovering the nuclear pollutants and treating them separately.

[0075] Based on the above embodiments and optional embodiments, the present invention proposes an optional implementation mode, which consists of four parts: a wrapping bag (flexible wrapping bag body 201), a negative pressure disinfection device (disinfection device), an adjustable atomization nozzle 102, and a wrapping bag tie / closing knot (wrapping bag tie device 202).

[0076] The wrapping bag and the negative pressure disinfection device are used to fix the rear end of the wrapping bag and connect the disinfection water source. The negative pressure disinfection device is a quick-plug interface, which is used to connect the accessory to the handle of the negative pressure disinfection device; the middle of the interface is the tail water pipe of the adjustable atomizing nozzle 102, which matches and docks with the water outlet in the handle of the negative pressure disinfection device; the nozzle 102 is surrounded by a waste liquid negative pressure recovery channel (reflux channel 301), and there is a filtering device (filter 303) in the middle of the reflux channel 301, which can be used to filter and recover solid impurities in the waste liquid; the filter 303 includes a plurality of isolation plates, and the isolation plates are provided with filter holes. The diameter of the filter holes and the area occupancy rate of the particles that can pass through the filter holes can be adjusted. When in use, the filter efficiency and negative pressure recovery power of the device can be adjusted by adjusting the diameter or the area occupancy rate.

[0077] The adjustable atomizing nozzle 102 is used to atomize the water column so that the disinfection reagent can better contact the skin of the extremities of the personnel, especially the gaps between the fingers, thereby improving the disinfection efficiency. The front end of the atomizing nozzle 102 is provided with a rotatable nozzle fixing cap (screw cap 103). By twisting the screw cap 103, the atomization degree of the disinfection reagent by the nozzle 102 can be adjusted; at the same time, a universal connecting shaft 104 is provided between the nozzle 102 and the water spraying pipe 101, which can adjust the direction by 360°, so as to realize the adjustment of the spray angle of the disinfection reagent during cleaning.

[0078] The flexible wrapping bag body 201 is used to wrap the extremities of the human body. The flexible wrapping bag body 201 is made of medical PVC material, and the bag body has high strength, good stability, and is not easy to be damaged; the bag body is sterilized with ethylene oxide; at the same time, the bag body has good flexibility, elasticity, environmental cracking resistance, and high and low temperature resistance; it does not contain plastic softeners (DEHP) for chemical industry that are harmful to the human body and the environment, and there is no DEHP leaching. The front end of the flexible wrapping bag body 201 is a wrapping bag tie / closing knot (wrapping bag tie 202), and the wrapping bag tie 202 is fixed to the bag body by hot melting or hot pressing; the rear end of the flexible wrapping bag body 201 is connected to the negative pressure washing device, and the front end of the bag body negative pressure washing device is sealed and fixed by flange or valve. This fixing method can ensure the sealing of the flexible wrapping bag body 201 and the negative pressure washing device, and realize the convenient disassembly, assembly and replacement of the flexible wrapping bag body 201. When the flexible wrapping bag body 201 itself is contaminated with radioactivity and there are still radionuclides or contaminated substances remaining after self-cleaning, the flexible wrapping bag body 201 can be directly replaced to ensure that when the next person or another limb is disinfected, no new radioactive contamination or other cross infection will be caused to the cleaned part.

[0079] The opening of the flexible wrapping bag body 201 is used for inserting or removing the extremities; and when an extremity is inserted, the wrapping bag mouthpiece 202 can be used to seal the wrapping bag. The wrapping bag mouthpiece 202 uses a Velcro 2022 closing method. When the extremity is inserted into the flexible wrapping bag body 201, the extremity and the flexible wrapping bag body 201 can be sealed by wrapping and sticking the Velcro 202. Through the sealing of the wrapping bag mouthpiece 202, a closed space can be formed inside the flexible wrapping bag body 201 during cleaning, thereby cooperating with the decontamination device to achieve negative pressure recovery of waste liquid (nuclear contaminated water); at the same time, with the wrapping bag mouthpiece 202, it can effectively prevent the radioactive waste liquid from splashing or flowing along the extremities during the decontamination process.

[0080] The present invention can recover radioactive waste liquid under negative pressure while decontaminating human extremities, thereby effectively avoiding the flow and spraying of radioactive waste liquid; at the same time, it can solve the problems of difficult cleaning of extremities and secondary contamination during operation. When the present invention is used to decontaminate the hands, feet, fingers, or toes of a person, especially when the gaps between the fingers or toes of the person being washed are contaminated by radioactive nuclides, the decontamination reagent can form an efficient flushing and complete soaking effect on the cleaned part in the package bag, thereby effectively improving the decontamination efficiency of the decontamination process.

[0081] In addition, it is still necessary to explain that the optional or preferred implementation of this embodiment can refer to the relevant description in the embodiment, which will not be repeated here.

[0082] The above sequence of the embodiments of the present invention is for description only and does not represent the superiority or inferiority of the embodiments.

[0083] In the above embodiments of the present invention, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0084] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
