Description

Technical Field

[0001] This invention relates to the field of animal tissue collection technology, and more specifically, to a portable animal tissue collection device. Background Technology

[0002] When collecting animal tissue, the animal is fixed in an upright or semi-recumbent position. The local skin is shaved, disinfected, and anesthetized. A three-way connector is connected between the puncture needle and the syringe. The person uses the thumb and forefinger of the left hand to tighten the local skin, and holds the puncture needle with the right hand, inserting it vertically close to the lower edge of the rib. When puncturing the intercostal muscle, a certain resistance is generated. When the resistance disappears and there is a feeling of emptiness, it means that the pleural cavity has been punctured. The pleural effusion is slowly aspirated and stored in the collection device, or the solid animal tissue is cut out and placed in the solid bag for storage.

[0003] Patent application publication number CN206847965U discloses a portable animal tissue collection device, comprising: a collection bag, which includes an inner bag and an outer bag, the outer bag including a vacuuming area at the upper end and a sealing area at the lower end of the vacuuming area; a vacuuming device, which includes an air extraction end connected to the vacuuming area; and a sealing device for sealing the sealing area. This invention allows for portable preservation of collected animal tissue, facilitates transportation of collected animal tissue, reduces virus degradation, thereby increasing the virus detection rate, and prevents cross-contamination caused by improper storage of pathogens, thus contributing to biosafety.

[0004] However, when using the above-mentioned collection device, solid animal tissues need to be placed inside the bag and then vacuumed using a vacuuming device for storage. Liquid animal tissue fluids need to be collected using a separate bag. This requires the use of different bags for collection. Without one type, collection cannot be carried out. Personnel have to carry two collection devices, which is inconvenient for efficient use and has poor applicability. Summary of the Invention

[0005] The present invention addresses the problem that existing technologies offer overly simplistic solutions and provides a significantly different approach. To overcome the aforementioned deficiencies of existing technologies, the present invention provides a portable animal tissue collection device to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable animal tissue collection device, comprising an upper pressure plate, a silicone compression airbag bonded to the lower part of the upper pressure plate, and a switching mechanism connected to the bottom end of the silicone compression airbag;

[0007] The switching mechanism includes a support threaded bottom cover connected to the bottom of the silicone air bladder, and a liquid collection tube is embedded in the top of the silicone air bladder. A vortex suction tube with a vortex-shaped cross-section is installed at the top of the liquid collection tube. A control valve for controlling the vortex suction tube is installed at one end of the vortex suction tube. A connecting threaded tube with an internal thread is connected to one end of the control valve. A recessed ring block is embedded at the top of the upper pressure plate and at one side of the vortex suction tube. The bottom of the inner wall of the recessed ring block is connected to an air outlet component.

[0008] Preferably, the bottom of the inner wall of the silicone compression airbag is made of solid metal. The silicone compression airbag is threadedly connected to the supporting threaded bottom cover. The second one-way valve is located inside the limiting isolation plate. The air outlet assembly includes a first one-way valve connected to the top of the recessed ring block. A compression placement groove is provided inside the silicone compression airbag. The second one-way valve and the limiting isolation plate are installed inside the compression placement groove. An exhaust pipe is installed at the top of the first one-way valve. The first one-way valve is threadedly connected to the recessed ring block after being wrapped with PTFE tape. A support ring is provided outside the liquid collection pipe and below the vortex suction pipe. The support ring is made of nylon.

[0009] Preferably, a sealing assembly is installed on the upper surface of the upper pressure plate, and the sealing assembly includes a limiting cover plate disposed on the upper surface of the upper pressure plate. A limiting arc-shaped block is provided on one side of the outer wall of the limiting cover plate, and a connecting block is fixed on the other side of the outer wall of the limiting cover plate. A rotating ring is welded to one side of the connecting block, and a positioning support rod is installed inside the rotating ring. A linkage spring is provided on the outer wall of the positioning support rod above the rotating ring. A movable ring is welded to the top of the linkage spring. A compression spring is installed on the outer wall of the positioning support rod at the top of the movable ring. A fixed support block is welded to the top of the compression spring. The movable ring and the rotating ring are movably connected to the outer wall of the positioning support rod. The outer wall of the positioning support rod is polished. The outer wall of the positioning support rod is welded and fixed to the inner wall of the fixed support block. Both the fixed support block and the positioning support rod are made of stainless steel.

[0010] Preferably, the upper cover plate has first concave support blocks on both sides of its outer wall, and a linkage extrusion assembly is welded inside the first concave support block. The linkage extrusion assembly includes a hinge shaft welded inside the first concave support block, and a collar hinge rod is hingedly fitted on the outer wall of the hinge shaft. A first pull ring is welded to one side of the inclined surface of the collar hinge rod. A support shaft is movably connected inside the collar hinge rod near its bottom end. A hinge collar rod is provided on the outer wall of the support shaft and on one side of the collar hinge rod. A second pull ring is provided on one side of the inclined surface of the hinge collar rod. A fixed support shaft is provided inside the hinge collar rod and near its bottom end. A second concave support block with a concave cross-sectional shape is fixed at one end of the fixed support shaft. The two first concave support blocks are symmetrically arranged about the center point of the upper cover plate. A limiting ring is provided on the outer wall of the support shaft and on the opposite side of the collar hinge rod and the hinge collar rod. The limiting ring is fixedly connected to the support shaft by welding.

[0011] The technical effects and advantages of this invention are as follows:

[0012] 1. This invention employs a switching mechanism and an air outlet assembly to rotate the threaded bottom cover. The threaded bottom cover and the silicone compression airbag are separated by the threads. The air below the limiting isolation plate is compressed and discharged upward through the second one-way valve into the space above the limiting isolation plate. It is then discharged upward through the first one-way valve inside the recessed ring block, completing the vacuuming operation. The control valve is connected to the puncture needle tube. Under the action of the rebound force of the silicone compression airbag, the connecting screw tube generates suction, and the cavity fluid is drawn into the control valve and finally collects at the position above the limiting isolation plate. This enables the storage and collection of animal solid and liquid tissues. Compression can create a vacuum, and degassing allows for the self-absorption of animal liquid tissues. This makes it more applicable, allowing for direct collection of both solid and liquid tissues, resulting in higher collection efficiency and easier portability.

[0013] 2. The present invention uses a capping assembly where the thumb presses down on the upper surface of the fixed support block, and the index and middle fingers are positioned on either side of the linkage spring. This allows the movable ring to be lifted upwards, and the linkage spring no longer presses against the rotating ring. The upper pressure plate is tilted, and the limiting plate no longer contacts the limiting arc block under the action of gravity. The connecting block drives the rotating ring to rotate at the outer wall of the positioning support rod. Under the action of gravity, the limiting plate no longer seals the area above the vortex suction pipe and exhaust pipe. Under the action of gravity, the vortex suction pipe can be quickly tilted and moved out from inside the upper pressure plate, making it convenient to quickly remove the vortex suction pipe for use.

[0014] 3. The present invention uses a linkage squeezing assembly to insert the index finger and little finger into the first and second pulling rings respectively. The two hands squeeze each other, and the second pulling ring drives the hinged collar rod to move. In this way, the collar hinge rod rotates outside the hinge shaft, and the support shaft can move closer to the position of the silicone compression airbag. The first concave support block can drive the upper pressure cover plate to stretch the silicone compression airbag upward, increase the suction force in the space above the limiting isolation plate inside the silicone compression airbag, speed up the extraction of pleural effusion, and increase the speed of aspirating animal liquid tissue.

[0015] In summary, through the interaction of the above-mentioned multiple functions, both solid and liquid animal tissues can be stored and collected. Under the influence of gravity, the vortex suction tube can be quickly tilted and moved out from inside the upper pressure plate, which facilitates the rapid removal of the vortex suction tube for use. The suction force inside the silicone compression airbag located in the space above the limiting isolation plate is increased, which speeds up the extraction of pleural effusion and improves the speed of aspirating animal liquid tissue. In summary, this method can achieve better applicability and collect both solid and liquid tissues, thereby improving the collection efficiency during the solid and liquid collection process.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] As attached Figure 1-9 The illustration shows a portable animal tissue collection device. This device includes a switching mechanism, an air outlet assembly, a sealing assembly, and a linkage compression assembly. These mechanisms and components are configured to collect both solid and liquid tissue fluid from animals. The specific structural configuration of each mechanism and component is as follows:

[0028] In some embodiments, as shown in the appendix Figure 1-4As shown, the switching mechanism includes a support threaded bottom cover 3 connected to the bottom of the silicone air bladder 2, and a liquid collection tube 4 is embedded in the top of the silicone air bladder 2. A vortex suction tube 5 with a vortex-shaped cross-section is installed at the top of the liquid collection tube 4. A control valve 6 for controlling the vortex suction tube 5 is installed at one end of the vortex suction tube 5. A connecting threaded pipe 7 with internal threads on the inner wall is connected to one end of the control valve 6. A recessed ring block 8 is embedded in the top of the upper pressure plate 1 at a position on one side of the vortex suction tube 5. The bottom of the inner wall of the recessed ring block 8 is connected to an air outlet component. The bottom of the inner wall of the silicone air bladder 2 is made of solid metal. The silicone compression airbag 2 is threadedly connected to the support threaded bottom cover 3. The second one-way valve 33 is located inside the limiting isolation plate 32. The top of the first one-way valve 9 is equipped with an exhaust pipe 10, and the first one-way valve 9 is threadedly connected to the recessed ring block 8 after being wrapped with PTFE tape. A support ring 11 is provided outside the liquid collection pipe 4 and below the vortex suction pipe 5. The support ring 11 is made of nylon material. The air outlet component includes the first one-way valve 9 connected to the top of the recessed ring block 8. The silicone compression airbag 2 has a compression placement groove 12 inside. The second one-way valve 33 and the limiting isolation plate 32 are installed inside the compression placement groove 12.

[0029] In this embodiment, after the animal solid tissue is cut off, the supporting threaded bottom cover 3 can be rotated. The supporting threaded bottom cover 3 and the silicone compression airbag 2 are separated by the thread. The gap between the lower part of the limiting isolation plate 32 and the supporting threaded bottom cover 3 is opened, and the animal solid tissue is placed in it. Then, the supporting threaded bottom cover 3 and the silicone compression airbag 2 are reversed to form a threaded connection and close. The limiting cover plate 13 is opened, and the upper pressure cover plate 1 is pressed down. The upper pressure cover plate 1 drives the silicone compression airbag 2 to press down. The supporting threaded bottom cover 3 can support the silicone compression airbag 2. Therefore, the air below the limiting isolation plate 32 can be squeezed and discharged upward through the second one-way valve 33 into the space above the limiting isolation plate 32. The air formed in the space above the limiting isolation plate 32 enters the interior of the recessed ring block 8 under the action of the squeezing force, and is discharged upward through the first one-way valve 9 inside the recessed ring block 8, and then discharged through the exhaust pipe 10.

[0030] When the silicone compression airbag 2 is fully compressed, a vacuum is created in the space below the limiting isolation plate 32. The upper pressure plate 1 is tilted, causing the control valve 6 to move out of the upper pressure plate 1 under gravity. The control valve 6 then moves the vortex suction tube 5 from the recessed position at the top of the silicone compression airbag 2. The control valve 6 is then connected to the puncture needle tube, opening it. Under the rebound force of the silicone compression airbag 2, suction is generated in the connecting screw tube 7, drawing the pleural fluid into the control valve 6. The fluid then flows through the control valve 6 into the vortex suction tube 5, and from there into the liquid collection tube 4. The pleural effusion enters the silicone compression airbag 2 and is positioned above the limiting isolation plate 32, allowing for the adsorption of both solid and liquid animal tissues. Compression creates a vacuum, and degassing allows for the automatic aspiration of the animal's liquid tissue, making it more versatile.

[0031] In some embodiments, as shown in the appendix Figure 4-6 As shown, a sealing assembly is installed on the upper surface of the upper cover plate 1, and the sealing assembly includes a limiting cover plate 13 disposed on the upper surface of the upper cover plate 1. A limiting arc-shaped block 14 is provided on one side of the outer wall of the limiting cover plate 13, and a connecting block 15 is fixed on the other side of the outer wall of the limiting cover plate 13. A rotating ring 16 is welded to one side of the connecting block 15. A positioning support rod 19 is installed inside the rotating ring 16. A linkage spring 17 is provided on the outer wall of the positioning support rod 19 and above the rotating ring 16. A movable ring 18 is welded to the top of the linkage spring 17. A compression spring 20 is installed on the outer wall of the positioning support rod 19 and at the top of the movable ring 18. A fixed support block 21 is welded to the top of the compression spring 20. The movable ring 18 and the rotating ring 16 are both movably connected to the outer wall of the positioning support rod 19. The outer wall of the positioning support rod 19 is polished. The outer wall of the positioning support rod 19 is welded and fixed to the inner wall of the fixed support block 21. Both the fixed support block 21 and the positioning support rod 19 are made of stainless steel.

[0032] In this embodiment, when it is necessary to open the limiting cover 13, the thumb can be pressed against the upper surface of the fixed support block 21, and the index and middle fingers can be positioned on both sides of the linkage spring 17. This lifts the movable ring 18 upwards, causing the linkage spring 17 to no longer press against the rotating ring 16. The movable ring 18 then causes the compression spring 20 to compress on the fixed support block 21. The rotating ring 16 is no longer subjected to the downward pressing force of the linkage spring 17, thus tilting the cover 1 upwards. Under the action of gravity, the limiting cover 13... No longer in contact with the limiting arc block 14, the limiting cover plate 13 drives the connecting block 15 to rotate, and the connecting block 15 drives the rotating ring 16 to rotate at the position of the positioning support rod 19 on the outer wall. In this way, under the action of gravity, the limiting cover plate 13 no longer seals the position above the vortex intake pipe 5 and the exhaust pipe 10, thus quickly opening the limiting cover plate 13. After the limiting cover plate 13 is opened, the movable ring 18 is directly released. Under the action of the rebound force of the compression spring 20, the linkage spring 17 is pressed against the upper surface of the rotating ring 16 to achieve locking and fixation.

[0033] In some embodiments, as shown in the appendix Figure 1 and 7 As shown in Figure -8, both sides of the outer wall of the upper pressure plate 1 are provided with first concave support blocks 22, and a linkage extrusion assembly is welded inside the first concave support block 22. The linkage extrusion assembly includes a hinge shaft 23 welded inside the first concave support block 22, and a collar hinge rod 24 is hingedly fitted on the outer wall of the hinge shaft 23. A first pull ring 25 is welded to one side of the inclined surface of the collar hinge rod 24. A support shaft 26 is movably connected inside the collar hinge rod 24 and near its bottom end. A hinge is provided on the outer wall of the support shaft 26 and on one side of the collar hinge rod 24. The connecting collar rod 27 has a second pull ring 28 on one side of the inclined surface of the connecting collar rod 27. A fixed support shaft 29 is provided inside the connecting collar rod 27 and near its bottom end. A second concave support block 30 with a concave cross-sectional shape is fixed at one end of the fixed support shaft 29. Two first concave support blocks 22 are symmetrically arranged about the center point of the upper pressure plate 1. The outer wall of the support shaft 26 and the opposite side of the collar hinge rod 24 and the connecting collar rod 27 are provided with limiting rings 31. The limiting rings 31 are fixedly connected to the support shaft 26 by welding technology.

[0034] In this embodiment, when the silicone compression airbag 2 is compressed and the cavity fluid needs to be quickly aspirated, both hands are positioned on either side of the first concave support block 22, with the index finger and little finger inserted into the first pull ring 25 and the second pull ring 28 respectively. The two hands squeeze against each other, causing the collar hinge rod 24 to move the support shaft 26, and the second pull ring 28 to move the hinge collar rod 27. This causes the collar hinge rod 24 to rotate outside the hinge shaft 23, and the first concave support block 22 supports the hinge shaft 23. The hinge collar rod 27 rotates outside the fixed support shaft 29, and the second concave support block 22... The shaped support block 30 supports the fixed support shaft 29, and the support shaft 26 can move closer to the position of the silicone compression airbag 2. The collar hinge rod 24 drives the hinge shaft 23 to move upward, and the hinge shaft 23 drives the first concave support block 22 to move upward. The first concave support block 22 can drive the upper pressure plate 1 to move upward, so that the upper pressure plate 1 can drive the silicone compression airbag 2 to be stretched upward. In this way, the silicone compression airbag 2 generates an upward pulling force in the space above the limiting isolation plate 32, which increases the suction force in the space above the limiting isolation plate 32 and speeds up the drainage of pleural effusion.
