[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model uses a bag body to form a sealed space, isolating the inside of the bag from the external environment, protecting anatomical personnel, reducing the risk of disease, preventing pollutant sputtering, and reducing the emission of irritating harmful gases. The bag body wraps an inflatable support frame. After the two are completely compressed, they have a small volume and are convenient to carry. The sealing strips on both sides of the zipper can be pasted to the other side after the release paper of the sealing adhesive sticker is torn off, preventing pollutants inside the bag from escaping outside the bag. The inflatable support frame can be quickly deployed to create anatomical conditions. At the same time, the gas inside the inflatable support frame is isolated from the gas inside the bag body, reducing the possibility of pollution.

[0021] Furthermore, the inflatable support frame includes a plurality of interconnected columns that are inflated together to support the bag body with a stable structure.

[0022] Furthermore, the inflatable support frame is provided with an instrument tray for holding anatomical instruments, preventing the instruments from piercing the bag body and the inflatable support frame, and facilitating the search for instruments. The bottom surface of the instrument tray is provided with magnetic stickers to adsorb and fix ferromagnetic anatomical instruments.

[0023] Furthermore, a specimen-taking table is provided. The operation of cutting the specimen is carried out on the specimen-taking table to prevent the bag body from being damaged. The inflatable support frame is provided with a specimen-taking table fixing ring to prevent the tabletop from moving during specimen-taking.

[0024] Furthermore, the double heads of the zipper are not completely closed to form a communication port. The communication port ensures that the inflation valve is located outside the bag while the inflatable support frame is located inside the bag. Water pipes and wires can enter the bag through the communication port. After the pipelines are set up, the communication port is sealed with a sealing strip to isolate the internal and external environments.

[0025] Furthermore, the glove cuff and the bag body can be connected through two mutually nested rings. In addition to the already fixed gloves, additional gloves can be added at other positions before dissection for easy operation.

[0026] Furthermore, both the bag body and the inflatable support frame are made of transparent materials, which do not affect observation while isolating the external environment. If it needs to be used again, the transparent materials are also convenient for finding the contaminated areas and are easy to clean and disinfect.

[0027] Furthermore, the bag body is provided with a plurality of observation pieces, through which anatomical personnel can observe, take pictures, and obtain photographic evidence, avoiding the influence of bag body wrinkles and reflections on observation and evidence collection.

[0028] Furthermore, the bag body is provided with a disinfection port. After the dissection is completed, disinfectant can be sprayed into the bag through this port for harmless treatment. The thin film inside the port can isolate the internal and external environments after the disinfection cover is opened and before disinfection, and can wrap the nozzle of the disinfection spray pot during disinfection to prevent the polluted gas inside the bag from escaping. When the disinfection port and the disinfection cover are rotationally assembled, the bag body between them is sealed to isolate the internal and external environments and prevent pollution. The disinfection port can also be used as a channel for the gas inside the bag to be discharged when deflating to balance the air pressure. Description of the Drawings

The diameter of the outer ring 1321 is slightly larger than that of the inner ring 1322. The width of the inner ring 1322 is slightly wider than that of the outer ring 1321. On both sides of the connection between the inner ring 1322 and the outer ring 1321, there is a circle of protrusions 13221. The slope of the protrusions 13221 near the center side of the inner ring 1322 is steeper, and the slope away from the center side of the inner ring 1322 is gentler, so that the outer ring 1321 is easy to be inserted into the inner ring 1322 and is not easy to fall out after being inserted into the inner ring 1322.

[0053] On the top surface 113 of the bag body 1, there are two pairs of rectangular viewing pieces 14. The viewing pieces 14 can be bent but are difficult to fold. When the inflatable support frame 2 is inflated, the viewing pieces 14 can support the top and prevent the top from collapsing. The two pairs of viewing pieces 14 are respectively located between the vertical projections of the front arch column 221 and the middle arch column 222 on the top surface 113 and between the vertical projections of the middle arch column 222 and the rear arch column 223 on the top surface 113. There is a certain distance between each pair of viewing pieces 14, and the distance between adjacent viewing pieces 14 is an integer multiple of the distance between the two viewing pieces in a pair, so that the entire bag body 1 can be folded by bending the bag body 1 between the viewing pieces 14. The width of the viewing piece 14 is equal to the distance between the top left column 214 and the top right column 215. At the connection of the viewing piece 14 and the bag body 1, a viewing piece opening 163 is provided on the bag body 1. The size of the viewing piece 14 is slightly larger than the size of the viewing piece opening 163, and the viewing piece 14 is adhesively bonded or heat-sealed to the outer side surface of the bag body 1 of the viewing piece opening 163.

[0054] On each of the front side surface 111 and the rear side surface 112 of the bag body 1, there is a disinfection port 15. As Figure 5 shown, the disinfection port 15 is provided with a disinfection port thread 151, a disinfection port fixing piece 152, a disinfection cover 153 and a film 154. The disinfection port 15 is a hollow cylindrical pipe. The disinfection port 15 is located on the bag body 1 near the arch column 22 between the horizontal projections of the arch column 22 and the zipper 12 on the bag surface 11. At the connection of the disinfection port 15 and the bag body 1, a disinfection port opening 164 is provided on the bag body 1. The outer diameter of the hollow cylindrical pipe of the disinfection port 15 is equal to the diameter of the disinfection port opening 164. The disinfection port 15 is provided with a disinfection port thread 151 around the outer periphery of the bag body 1. The disinfection port 15 extends around the inside of the bag body 1 into a circular disinfection port fixing piece 152. The axis of the disinfection port 15 is perpendicular to the surface of the bag body 1. The disinfection port 15 is adhesively fixed to the inner side surface of the bag body 1 of the disinfection port opening 164 through the disinfection port fixing piece 152. The inner side surface of the disinfection cover 153 is provided with a disinfection cover thread 1531. The disinfection cover 153 is rotationally assembled with the disinfection port thread 151 of the disinfection port 15 through the disinfection cover thread 1531. The height of the edge of the disinfection cover 153 is greater than the height of the cylindrical pipe of the disinfection port 15, so that the bag body 1 between the two is sealed when the disinfection port 15 and the disinfection cover 153 are assembled. The film 154 is adhesively fixed around the outer periphery of the bag body 1 with the disinfection port 15. The film 154 is perpendicular to the axis of the disinfection port 15.

[0055] At least one rectangular instrument tray 24 is provided at the top of each of the bottom left column 211, bottom right column 212, and bottom front column 213. A magnetic sticker 241 is provided on the bottom surface of the instrument tray 24. The magnetic sticker 241 is adhesively bonded to the instrument tray 24 or connected by magnetic adsorption. The instrument tray 24 is adhesively bonded to the column body. The instrument tray 24 is located below the observation piece 14 of the bag body 1. The distance between the instrument trays 24 on the same column body of the bottom left column 211 or bottom right column 212 is an integer multiple of twice the distance between a pair of observation pieces 14, so that the instrument trays 24 can be buckled with each other when the bag body 1 is folded. At least one sampling table fixing ring 25 is provided on the outer surfaces of the right side of the bottom left column 211 and the left side of the bottom right column 212. The sampling table fixing ring 25 is adhesively bonded or heat-melted to the outer surfaces of the right side of the bottom left column 211 and the left side of the bottom right column 212. The sampling table fixing ring 25 closest to the rear arch column 223 is located near the rear arch column 223 between the middle arch column 222 and the rear arch column 223.

[0056] As Figure 4 shown, the sampling table 3 includes a tabletop 31, support legs 32, and hinge hinges 33. The tabletop 31 is rectangular, and the width is equal to the net distance between the air columns on the left and right sides of the bottom of the inflatable support frame 2. The tabletop 31 is provided with a specimen box holder 311. The specimen box 4 is placed on the tabletop 31 of the sampling table 3 through the specimen box holder 311. The specimen box 4 can be placed in the specimen box holder 311 in advance, which is convenient for directly placing the specimen box 4 after the specimen is extracted, preventing the specimen box 4 from tipping over and causing pollution. The inner diameter of the specimen box holder 311 is slightly larger than the outer diameter of the box body 41 of the specimen box 4, and the inner diameter of the specimen box holder 311 is smaller than the outer diameter of the box body fixing ring 413 of the specimen box 4, preventing the specimen box 4 from completely passing through the tabletop 31. Support legs 32 are provided at the four corners of the bottom surface of the tabletop 31. One end of each support leg 32 is fixed to the hinge hinge 33 by screws, and the hinge hinge 33 is fixed to the bottom of the tabletop 31 by screws. When folded, the support legs 32 fold inward towards the tabletop 31, reducing the storage volume. The sampling table 3 is fixed to the inner sides of the air columns on the left and right sides of the bottom of the inflatable support frame 2 by inserting the unfolded support legs 32 into the sampling table fixing ring 25.

[0057] The specimen box includes a box body 41 and a box cover 42. The box body 41 includes a box body thread 411, a box mouth 412, and a box body fixing ring 413. The outer side surface of the box body 41 near the box mouth 412 is provided with a box body thread 411. The inner side surface of the box cover 42 is provided with a box cover thread 421. The box body fixing ring 413 is located below the box body thread 411 near the thread. The box cover 42 is rotationally assembled with the box body thread 411 of the box body 41 through the box cover thread 421.

[0058] The working process of the present utility model is as follows:

[0059] During use, it goes through steps such as laying, placing, inflating, dissecting, disinfecting, and deflating. Before laying, the dissecting personnel should do a good job in their own protection. When laying, lay a regular body bag with the zipper 12 opened flat on the dissecting operation surface. Take out the biosafety dissecting bag from the package, unfold and lay it on the regular body bag to prevent the dissecting operation surface from damaging the bottom surface 114 of the bag body 1. At this time, if additional gloves 13 are needed, use the snap rings 132 in the other package to fix the gloves 13 on the corresponding bag surface 11. When the snap rings 132 are engaged, the glove cuff 131 and the glove opening 162 are clamped between the two rings, so as to fix the additional gloves 13 on the bag surface 11 and ensure the airtightness of the bag body 1. When placing, lift the part above the bottom surface 114 through the part where the bottom right column 212 is longer than the bag body 1. Place the body, dissecting instruments, the unpacked specimen table 3, and the specimen box 4 at appropriate positions respectively. The head of the body lies supine facing the front side 111, on the bottom surface 114 and between the bottom left column 211, the bottom right column 212, and the bottom front column 213 without pressing on the air column. The dissecting instruments are placed on the instrument tray 24, and the specimen table 3 and the specimen box 4 are placed near the rear side 112. When it is necessary to supply water and electricity into the bag, the water pipe and the wire enter the bag body 1 through the inner side of the zipper 12 at the part where the bottom right column 212 is longer than the bag body 1. Cover the lifted part and zip up the zipper 12 so that the zipper 12 is not completely closed at the part where the bottom right column 212 is longer than the bag body 1. The bottom surface 114 of the instrument tray 24 is provided with magnetic stickers 241, which can adsorb and fix ferromagnetic dissecting instruments. During inflation in the use process, use an air pump to pump air into the inside of the inflation support frame 2 through the inflation valve 23 on the inflation support frame 2. Since the columns of the inflation support frame 2 are all interconnected hollow pipes and there is only one opening 16 communicating with the outside, which is the inflation valve 23, under the action of the internal air pressure, the inflation support frame 2 gradually bulges. Under the action of the straight column 21 at the bottom, it supports structures such as the instrument tray 24. Since the outer shape of the bag body 1 can wrap the inflation support frame 2 and it has been assembled during production, under the combined action of the straight column 21 and the arch column 22, it firmly supports the bag surface 11 and the zipper 12, gloves 13, observation piece 14, disinfection port 15, etc. on the bag surface 11, forming a closed dissecting environment inside the bag body 1 and providing enough operating space for the dissecting personnel. During inflation, since the inside of the pipe of the inflation support frame 2 is not directly connected to the inside of the bag body 1, under the action of the inflation support frame 2, the bag body 1 shows an expanding trend, so that the gas pressure inside the bag body 1 is less than the external atmospheric pressure during the entire inflation process, and the relatively closed bag body 1 is in a negative pressure state. Therefore, the contaminated air inside the bag body 1 will not escape to the external environment, ensuring the cleanliness of the external environment during the inflation process. After the inflation support frame 2 is filled with gas, withdraw the air pump from the inflation valve 23, turn off the air pump and screw on the air cap of the inflation valve 23. Since the inflation valve 23 only allows gas to flow unidirectionally from the outside to the inside of the inflation support frame 2, the gas inside the inflation support frame 2 will not escape from the inflation valve 23 after the air pump is withdrawn.After inflation, tear off the release paper of the sealant sticker 1211, cover the sealing strip 12 around the zipper 12 to prevent leakage. Operate through the glove 13 on the rear side 112, insert the specimen-taking table 3 into the specimen-taking table fixing ring 25 through the deployed support legs 32, and fix it inside the air columns on the left and right sides of the bottom of the inflatable support frame 2. Place the specimen box 4 on the tabletop 31 of the specimen-taking table 3 through the specimen box holder 311. When dissecting and taking specimens from the corpse according to relevant national standards, operate using the glove 13 on the bag body 1. Additional gloves 13 can be worn on the hands before wearing the glove 13 on the bag body 1, or additional gloves 13 can be worn on the glove 13 of the bag body 1 after wearing the glove 13 of the bag body 1 to protect the glove 13 on the bag body 1. The unused instruments are placed in the instrument tray 24. Observe or take pictures or videos through the top viewing piece 14 or directly through the bag body 1. The specimen-taking is carried out on the specimen-taking table 3, and the specimens are placed in the specimen box 4. Before disinfection, rotate and tightly assemble the lid 42 of the specimen box 4 with the box body thread 411 of the box body 41 through the lid thread 421.

[0060] During disinfection, remove the disinfection cover 153 through the disinfection cover thread 1531 and the disinfection port thread 151 of the disinfection port 15. Use an atomizing sprayer filled with disinfectant to continuously spray the disinfectant. Spray the disinfectant on the disinfection port 15 and the surrounding environment outside the film 154 in sequence, penetrate into the bag through the film 154 of the disinfection port 15, and spray the disinfectant into the bag. The film 154 provided in the disinfection port 15 can isolate the internal and external environments before opening the disinfection cover 153 and before disinfection, and wrap the nozzle of the disinfection sprayer during disinfection to prevent the polluted gas in the bag from escaping. Flip the objects in the bag during spraying to spray the disinfectant comprehensively. After disinfection, tear off a part of the sealing strip 121 and unzip a part of the zipper 12 on the rear side 112, and take out the specimen box 4 from the bag body 1. When deflating during use, after removing the inflation valve 23 and the disinfection cover 153, under the action of the self-gravity of the bag body 1 and the inflatable support frame 2, the gas in the inflatable support frame 2 escapes from the inflation valve 23 port, and the gas in the bag body 1 escapes from the disinfection port 15. Since the gas in the bag has been disinfected by atomizing and spraying the disinfectant, the escaped gas will not pollute the external environment. When the gas in the bag and the inflatable support frame 2 escapes to a degree suitable for subsequent transportation and harmless treatment, install the inflation valve 23 and the disinfection cover 153 to prevent the contents in the bag from leaking during transportation. After deflation, put the biosafety dissection bag and its contents into a common corpse bag pre-laid at the bottom and zip up the corpse bag zipper.

[0061] During the production process, the biosafety dissection bag undergoes the processes of assembly, folding, and packaging. During the assembly process when inflating, after fully opening the zipper 12 of the bag body 1 and unfolding it on a flat surface, lay the uninflated inflatable support frame 2 on the bottom surface 114 of the bag body 1, align the bottom left column 211 of the inflatable support frame 2 with one side of the left intersection line of the top surface 113 and the bottom surface 114 of the bag body 1, align the bottom right column 212 with one side of the right intersection line of the top surface 113 and the bottom surface 114 of the bag body 1, align the bottom front column 213 with one side of the intersection line of the front side surface 111 and the bottom surface 114 of the bag body 1, use an air pump to fill the inflatable support frame 2 with gas, put the front side surface 111 and part of the top surface 113 of the bag body 1 over the front arch column 221 along the zipper opening 161, cover the rear side surface 112 and the remaining top surface 113 of the bag body 1 on the middle arch column 222 and the rear arch column 223, adjust the relative position of the bag body 1 and the inflatable support frame 2 so that it can exactly wrap the inflatable support frame 2, and the part of the bottom right column 212 that is longer than the part of the bag body 1 with the inflation valve 23 extends out of the bag body 1 between the zippers 12 to ensure that the inflatable support frame 2 can be inflated or supplemented with gas through the inflation valve 23 provided outside the bag body 1 during use. When deflating the inflatable support frame 2 and the bag body 1 before folding, after removing the inflation valve 23, under the action of the self - gravity of the bag body 1 and the inflatable support frame 2, the gas in the inflatable support frame 2 completely escapes from the inflation valve 23 port, and the gas in the bag body 1 completely escapes from between the zippers 12, keeping the corresponding position relationship between the bag body 1 and the inflatable support frame 2 unchanged, folding the arch columns 22 vertically downward and keeping the straight columns 21 straight, overlapping the area with the observation piece 14 in the center of the top surface 113 with the bottom surface 114, folding the gloves 13 on the front side surface 111 and the rear side surface 112 between the front arch column 221 and the bottom front column 213 or between the rear arch column 223 and the bottom surface 114, folding the gloves 13 on the top surface 113 between the straight columns 21 with the top and bottom located on the left - right same side respectively, rotating the disinfection cover 153 together with the disinfection cover thread 1531 and the disinfection port thread 151 of the disinfection port 15, and making the distance between the top left column 214 and the top right column 215 the largest.When folded, the part of the top surface 113 located outside the top right column 215 is folded along the top right column 215 and covers the central top surface 113 where the observation piece 14 is located. The part of the top surface 113 located outside the top left column 214 is folded between the top left column 214 and the bottom left column 211. Since there is a certain distance between each pair of observation pieces 14, and the distance between adjacent observation pieces 14 is an integer multiple of the distance between a pair of two observation pieces 14, the entire bag body 1 can be folded by bending the bag body 1 between the observation pieces 14. Since the distance between the instrument trays 24 on the same column, i.e., the bottom left column 211 or the bottom right column 212, is twice the distance between a pair of two observation pieces 14, the instrument trays 24 can be buckled with each other when the bag body 1 is folded. The folding of the bag body 1 starts from the front side 111 and successively folds through several observation pieces 14 on the top surface 113 to the back side 112, and then folds the parts located outside the top left column 214 and the top right column 215 on both sides of the observation pieces 14 after folding towards the center. The folded biosafety dissection bag is stored in a packaging bag. To prevent adhesion, an anti-adhesion agent can be sprinkled on the surfaces of non-connected structures. The material taking table 3 and the specimen box 4 are separately packaged. When the material taking table 3 is packaged and stored, the support legs 32 are folded towards the inside of the table top 31. The box cover 42 of the specimen box 4 is rotationally and hermetically assembled with the box body thread 411 of the box body 41 through the box cover thread 421.
