Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of inactivation tank devices, and in particular to a biosafety double-door animal carcass inactivation tank device. Background Technology
[0002] Animal carcass inactivation containers are essential equipment in large-scale animal biosafety laboratories. Due to their large size and high value, ideally each experimental area should be equipped with one, significantly increasing the construction cost of such laboratories. For example, CN118635251A discloses a horizontal high-level biosafety laboratory animal carcass processing device, comprising: a chamber with an inlet and an outlet; a support frame located at the lower part of the chamber; a partitioned sealing door located within the chamber, with the inlet and outlet situated on the left and right sides of the partitioned sealing door; a crushing device located above the outlet; and a feeding device for moving materials from the inlet to the other side of the partitioned sealing door.
[0003] Therefore, it is essential to invent a biosafety double-door animal carcass inactivation tank device that saves on the construction costs and floor space without affecting experimental operations. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a cost-reducing biosafety double-door animal carcass inactivation container device.
[0005] This utility model discloses a biosafety-compliant double-door animal carcass inactivation container device, comprising a laboratory in area A, a laboratory in area B, and a partition wall. The partition wall separates the laboratories in areas A and B. Below the laboratories in areas A and B is an underground inactivation chamber. The device also includes an isolation chamber, airtight door devices, and a dissection tray device. An isolation chamber spanning the laboratories in areas A and B is constructed on the partition wall. An inactivation container is installed in the underground inactivation chamber, with its top extending to the bottom of the inner side of the isolation chamber. An inlet is located at each of the left and right ends of the isolation chamber, and an airtight door device is located at each end of the isolation chamber. Each airtight door device seals one of the inlets. A dissection tray assembly is mounted on top of each airtight door device. The other end of the sealed door is placed on the ground. The staff operates the electric hoist to unwind the animal sling, then hooks the animal carcass onto the necessary position, moves the dissection tray assembly to one end of the sealing door and locks it, controls the electric hoist to operate, so that the animal sling lifts the animal carcass into the dissection tray assembly through the hook. Then, the staff uses the electric hoist and the first sling to make the sealing door horizontal, then moves one end of the dissection tray assembly to the edge of the inactivation tank opening, performs the dissection, locks the dissection tray assembly, and then the electric hoist rewinds the first sling, so that the first sling pulls the sealing door through the sling fixing piece, thus sealing the door to the inlet while the animal carcass on the dissection tray assembly falls into the inactivation tank under its own weight for fire extinguishing.
[0006] Preferably, the airtight door device includes a sealing door, a sling fastener, a first sling, an electric hoist, and an animal sling. One end of the sealing door is hinged to the laboratory in area A. A sling fastener is installed on the sealing door. An electric hoist is installed on the isolation chamber, and each hoist has a first sling and an animal sling. One end of the first sling is connected to the sealing door via the sling fastener, and one end of the animal sling has a hook. The other end of the sealing door is placed on the ground. Workers operate the electric hoist to unwind the animal sling, allowing the hook on the animal sling to hook onto the necessary part of the animal carcass, thus assembling the dissection tray. The device is moved to one end of the sealed door and locked. The electric hoist is then operated, allowing the animal sling to lift the animal remains into the dissection tray assembly via the hook. The operator coordinates the electric hoist with the first sling to make the sealed door horizontal, moving one end of the dissection tray assembly to the edge of the inactivation tank opening. After dissection, the dissection tray assembly is locked. Then, the electric hoist retracts the first sling, causing it to pull the sealed door through the sling fixing parts. This seals the door at the inlet while the animal remains on the dissection tray assembly fall into the inactivation tank under their own weight for fire extinguishing.
[0007] Preferably, the dissection tray assembly includes a dissection tray body, rollers, a sliding track, a track fixing seat, and a locking component. The sealing door is provided with a track fixing seat, and the sliding track is provided on the track fixing seat. The dissection tray body is slidably connected to the sliding track. Multiple sets of rollers are rotatably mounted on the top of the dissection tray body, and a locking component is provided on the dissection tray body. In use, the dissection tray body slides on the sealing door via the sliding track and is then locked by the locking component. When the hook on the animal sling pulls the animal remains, the animal remains move onto the dissection tray body with the cooperation of the multiple sets of rollers. Afterward, the sealing door is horizontal, the locking is released, and the dissection tray body moves the animal remains with the help of the dissection tray body. When one end of the dissection tray body approaches the inactivation tank, dissection is performed. After dissection, the locking component locks the dissection tray body, preventing it from sliding on the sliding track. Then, the first sling seals the sealing door to the inlet, and the dissection tray body follows the sealing door into a vertical position, allowing the dissected animal remains on the dissection tray body to enter the inactivation tank for fire extinguishing.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The other end of the sealed door is placed on the ground. The operator uses an electric hoist to unwind the animal sling, then hooks the animal carcass onto the necessary position. The dissection tray assembly is moved to one end of the sealed door and locked. The electric hoist is then controlled to move, allowing the animal sling to lift the animal carcass into the dissection tray assembly via the hook. The operator then uses the electric hoist in conjunction with the first sling to make the sealed door horizontal. Next, one end of the dissection tray assembly is moved to the edge of the inactivation tank opening for dissection. After dissection, the dissection tray assembly is locked. The electric hoist then moves to the first sling... The slings are wound up, causing the first sling to pull the sealing door through the sling fixing components. This seals the door to the entrance while the animal remains on the dissection tray fall into the inactivation tank under their own weight for fire extinguishing. The overall structure is simple and occupies a small area. It serves as both a sealing door and a dissection table. All waste and animal remains from the surgical procedure are disposed of in the inactivation tank, reducing environmental impact. Compared to current hoisting methods, it requires significantly less net height in the room, saving on construction costs. It also facilitates indoor space disinfection and sterilization operations and daily management. The isolation room is relatively small, making disinfection procedures easier.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0019] Example 1:
[0020] like Figures 1 to 8 As shown, this embodiment provides a biosafety double-door animal carcass inactivation container device, including an A-area laboratory 6, a B-area laboratory 7, and a partition wall 5. The partition wall 5 is provided between the A-area laboratory 6 and the B-area laboratory 7. The underground inactivation room is located below the A-area laboratory 6 and the B-area laboratory 7. The device also includes an isolation room 4, an airtight door device 1, and a dissection tray device. An isolation room 4 spanning the A-area laboratory 6 and the B-area laboratory 7 is provided on the partition wall 5. An inactivation container 3 is provided in the underground inactivation room. The top of the inactivation container 3 extends to the bottom of the inner side of the isolation room 4. An inlet is provided at each of the left and right ends of the isolation room 4. An airtight door device 1 is provided at each of the two ends of the isolation room 4. The two sets of airtight door devices 1 seal one set of inlets respectively. A dissection tray assembly is provided on each set of airtight door devices 1.
[0021] like Figures 1 to 8As shown, the airtight door device includes a sealing door 11, a sling fastener 16, a first sling 17, an electric hoist 18, and an animal sling 21. One end of the sealing door 11 is hinged to laboratory 6 in area A. The sealing door 11 is equipped with a sling fastener 16. An electric hoist 18 is installed on the isolation room 4. The electric hoist 18 is equipped with a first sling 17 and an animal sling 21. One end of the first sling 17 is connected to the sealing door 11 through the sling fastener 16. One end of the animal sling 21 is equipped with a hook.
[0022] In this embodiment, during use, the airtight door device 1 inside laboratory 6 in area A is opened, and the airtight door device 1 inside laboratory 7 in area B is closed. The other end of the sealed door 11 is placed on the ground. The operator operates the electric hoist 18 to unwind the animal sling 21, then hooks the hook on the animal sling 21 to the necessary position, moves the dissection tray assembly to one end of the sealed door 11 and locks it, controls the electric hoist 18 to operate, so that the animal sling 21 lifts the animal sling 2 into the dissection tray assembly through the hook. Then, the operator uses the electric hoist 18 in conjunction with the first sling 17 to make the sealed door 11 horizontal, and then... One end of the dissection tray assembly is moved to the edge of the inactivation tank 3 opening. After dissection, the dissection tray assembly is locked. Then, the electric hoist 18 winds up the first hoisting cable 17, causing the first hoisting cable 17 to pull the sealing door 11 through the hoisting cable fixing piece 16. This seals the inlet of the sealing door 11 and causes the animal remains 2 on the dissection tray assembly to fall into the inactivation tank 3 under its own weight for fire extinguishing. When there are animal remains 2 in laboratory 7 in area B, the above sequence can be followed. This allows laboratory 6 in area A and laboratory 7 in area B to share a set of inactivation tanks 3, which reduces experimental costs while ensuring experimental effectiveness.
[0023] Example 2:
[0024] like Figures 1 to 8 As shown, based on Embodiment 1, the dissecting tray assembly includes a dissecting tray body 12, rollers 13, a movable slide 14, a slide fixing seat 15, and a locking assembly. The sealing door 11 is provided with a slide fixing seat 15, and the slide fixing seat 15 is provided with a movable slide 14. The dissecting tray body 12 is slidably connected to the movable slide 14. Multiple sets of rollers 13 are rotatably provided at the top of the dissecting tray body 12, and a locking assembly is provided on the dissecting tray body 12.
[0025] In this embodiment, during use, the airtight door device 1 inside laboratory 6 in area A is opened, and the airtight door device 1 inside laboratory 7 in area B is closed. The other end of the sealed door 11 is placed on the ground. The operator operates the electric hoist 18 to unwind the animal sling 21, and then the hook on the animal sling 21 hooks onto the necessary position of the animal carcass 2. The dissection tray body 12 slides on the sealed door 11 via the moving slide 14 and is locked by the locking assembly. The animal carcass 2 moves onto the dissection tray body 12 with the cooperation of multiple sets of rollers 13. Then the sealed door 11 is in a horizontal state, the lock is released, and the dissection tray body 12 moves the animal carcass 2 with the cooperation of the dissection tray body 12. When one end of the body 12 is close to the inactivation tank 3, after dissection and dissection, the locking component locks the dissection tray body 12, preventing it from sliding on the moving slide 14. Then, the electric hoist 18 winds up the first hoisting cable 17, causing the first hoisting cable 17 to pull the sealing door 11 through the hoisting cable fixing part 16. This seals the inlet of the sealing door 11 and causes the animal remains 2 on the dissection tray to fall into the inactivation tank 3 under its own weight for fire extinguishing. When there are animal remains 2 in laboratory 7 in area B, the above sequence can be followed. This allows laboratory 6 in area A and laboratory 7 in area B to share a set of inactivation tanks 3, reducing experimental costs while ensuring experimental effectiveness.
