Description

Technical Field

[0001] This invention relates to the field of gastrointestinal decompression technology, and in particular to a gastrointestinal decompression device. Background Technology

[0002] A gastrointestinal decompression device is a medical device that uses negative pressure suction to remove accumulated gas and fluid from the gastrointestinal tract, thereby reducing intra-intestinal pressure, improving blood circulation in the gastrointestinal wall, promoting wound healing, and aiding in the recovery of gastrointestinal function. The outer casing of a gastrointestinal decompression device is typically made of plastic, which can be flattened. An internal elastic component allows for expansion. The device usually has an inlet and an outlet pipe; the inlet pipe connects to the gastric tube, and the outlet pipe is opened to drain water, allowing for reuse.

[0003] Existing gastrointestinal decompression devices are typically compressed and packaged in a bag. To use them, the bag must be opened, and the tube opening on the device must be opened before inserting the tube. The device will then expand. One hand presses down on the device to compress it, while the other hand inserts the tube into the opening. However, to expel as much air as possible, the device needs to be placed on a flat surface before pressing again, making the operation cumbersome and inefficient. Furthermore, food residue may be present in the liquid aspirated into the device. This residue can easily clog the tube's outlet before entering the device, affecting suction effectiveness. After food residue enters the gastrointestinal decompression device along with the liquid, it easily clogs the outlet pipe when the liquid is squeezed out. Typically, this is addressed by repeatedly squeezing the clogged section of the pipe joint, but the clearing effect is limited. If the blockage cannot be cleared, the gastrointestinal decompression device must be replaced, resulting in equipment waste. Furthermore, in some clinical situations, it is necessary to examine the food residue inside the gastrointestinal decompression device. In some cases, observation and diagnosis of the residue are required to help medical staff assess the patient's condition and treatment effectiveness. However, because the residue and liquid inside the decompression device are mixed, only the liquid can be observed from the outside, making it impossible to effectively observe and diagnose the residue. Therefore, this application provides a gastrointestinal decompression device to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a gastrointestinal decompression device to solve the problems of the existing gastrointestinal decompression devices being cumbersome to operate, difficult to effectively clear blockages, and not conducive to medical staff to observe and diagnose residues.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A gastrointestinal decompression device includes a decompression device body and a cannula. An inlet pipe and an outlet pipe are fixedly connected to the decompression device body, and the inlet pipe is inserted into the cannula. It also includes a processing component for turning the ventilation state of the decompression device body on or off and for treating liquid residue entering the decompression device body. The processing component is located in the decompression device body and is connected to the inlet pipe.

[0007] The processing assembly includes an elastic bladder, a reset plate, and a plug-in component located inside the water inlet pipe. The plug-in component includes a rubber block, one end of which is fixedly connected to an integral outer elastic sleeve and an inner elastic sleeve, forming a receiving area between the outer elastic sleeve and the inner elastic sleeve. The outer elastic sleeve wraps around the outer ring of the plug-in component. The other end of the rubber block is fixedly connected to an integral connecting piece and a compression piece. An elastic hole is provided inside the rubber block, which is inserted into the tube. A detachable locking rod is installed inside the elastic bladder, and a plug is fixedly connected to the top of the locking rod. The outer edge of the elastic hole protrudes inward to form a raised ring.

[0008] Optionally, the elastic bladder has several leakage holes on its peripheral side, and a slot is provided at the bottom of the elastic bladder. The bottom end of the locking rod is fixedly connected to a plug threaded to the slot. An annular piece is fixedly connected to the locking rod near the plug, and the connection between the annular piece and the plug is an arc-shaped protrusion.

[0009] Optionally, a bracket is fixedly connected at the connection between the locking rod and the insertion rod. The bracket includes a plurality of annularly arranged first support plates, the top ends of which are all bent inward, and each of the first support plates has a through hole.

[0010] Optionally, an elastic hopper is fixedly connected to the edge of the opening at the top of the elastic bladder, and the elastic hopper is fixedly connected to the connecting piece.

[0011] Optionally, the elastic bucket opening gradually expands outward to form a sloping wall, and an annular pad is fixedly connected to the edge of the elastic bucket opening.

[0012] Optionally, the pressure reducer body includes a rigid planar plate, which is located at the upper and lower ends of the pressure reducer body.

[0013] Optionally, a pair of support rings are installed inside the pressure reducer body, and the two ends of the reset plate are respectively fixed to the pair of support rings. The pair of support rings respectively abut against the inner surfaces of the two planar plates, and several connecting strips are fixedly connected inside each pair of support rings.

[0014] Optionally, the inlet pipe and the outlet pipe are located at the upper and lower ends of the pressure reducer body, respectively, and a sealing plug is inserted into the outlet pipe located at the lower end of the pressure reducer body.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above solution, by setting up a plug-in component, the pressure reducer body is in a compressed state in the initial state, and the locking rod passes through the elastic hole on the rubber block. The plug is located at the outer opening of the elastic hole for limiting, preventing the pressure reducer body from resetting in the compressed state, thus achieving a seal on the pressure reducer body. When the pressure reducer body is freed from the constraint of the locking rod, it can gradually expand and attract, so that when the cannula is connected to the pressure reducer body, there is no need to press the gastrointestinal pressure reducer again for compression, thereby simplifying the operation steps and improving the operation efficiency.

[0017] By incorporating an elastic bladder, when liquid enters the pressure reducer body through the inlet pipe, the mixture of liquid and residue first falls onto the elastic bladder. The sloping wall facilitates the flow of the mixture into the elastic bladder. As the liquid flows, the residue remains within the elastic bladder, while the liquid flows into the pressure reducer body through the seepage hole. This operation separates the mixture entering the pressure reducer body, ensuring that the residue remains within the elastic bladder and the liquid remains within the pressure reducer body. Therefore, the liquid will not cause blockage in the outlet pipe during subsequent discharge. Furthermore, the elastic bladder, with its top and flat panel forming a sealed connection, allows the liquid squeezed out of the residue within the elastic bladder to flow into the pressure reducer body through the seepage hole, further diverting the residue. The squeezed residue is also easier to remove in the next step.

[0018] By setting a locking rod, in addition to keeping the decompressor body in a compressed state, the locking rod can repeatedly insert into the end of the intubation tube to achieve the effect of unblocking the end of the intubation tube. The sharp design of the outer end of the plug makes it easier for the locking rod to insert into the residue blocking the intubation tube. Since there are several annular plates at the rear end of the plug, and the diameter of the annular plates is smaller than the diameter of the plug, the annular plates will not push the residue away. When the plug and the annular plates are inserted into the residue and then pulled out, the annular plates will carry the residue out of the intubation tube. By repeating this process, the end of the intubation tube can be unblocked, thus facilitating the cleaning and reuse of the gastrointestinal decompression device.

[0019] By setting several first support plates on the locking rod, when the locking rod is pulled out, the inwardly bent end is first compressed inward by the elastic hole, which further compresses the residue in the first support plates. The squeezed liquid flows out through the gaps between the first support plates and the through holes on the first support plates. The residue can be removed by continuing to pull the locking rod outward. The advantages of this are: firstly, it can clean the residue in the elastic bladder, making it convenient to reuse the decompression device; secondly, the removed residue is convenient for medical staff to observe and diagnose, solving the problem that the mixed liquid is not conducive to observation. In summary, the present invention has an ingenious structure and systematically optimizes the entire operation process. Attached Figure Description

[0048] like Figures 1 to 19As shown, an embodiment of the present invention provides a gastrointestinal decompression device, including a decompression device body 1 and a cannula 2. The cannula 2 is a flexible tube in the prior art, with plastic plugs at both ends. A water inlet pipe 3 and a water outlet pipe 30 are fixedly connected to the decompression device body 1. The water inlet pipe 3 is inserted into the cannula 2. The decompression device body 1 is also provided with an exhaust pipe, in which a rubber plug is inserted. The rubber plug is removed to perform an exhaust operation when needed. It also includes a processing component for opening or closing the ventilation state of the decompression device body 1 and for processing liquid residue entering the decompression device body 1. The processing component is located inside the decompression device body 1 and is connected to the water inlet pipe 3. The assembly includes an elastic bladder 8, a reset piece 7, and a connector 4 located inside the water inlet pipe 3. From top to bottom, the connector 4 and the elastic bladder 8 are arranged in sequence. The reset piece 7 is located on the outer periphery of the connector 4 and the elastic bladder 8. The connector 4 includes a rubber block 22. One end of the rubber block 22 is fixedly connected to an integral outer elastic sleeve 20 and an inner elastic sleeve 24. The outer elastic sleeve 20, the inner elastic sleeve 24, and the rubber block 22 are all made of rubber. A receiving area 27 is formed between the outer elastic sleeve 20 and the inner elastic sleeve 24. The receiving area 27 is used to receive the water inlet pipe 3. When the connector 4 is inserted into the water inlet pipe 3, the outer elastic sleeve 20 wraps around the outer ring of the connector 4, which can further reinforce it. The plug-in component 4 is used to prevent dislocation. The pressure reducer body 1 is in a compressed state when removed from the packaging bag. During use, the insertion tube 2 is inserted into the elastic hole 21 on the rubber block 22. The elastic rubber allows the elastic hole 21 to wrap around the insertion tube 2. The rubber block 22 has an elastic hole 21 that engages with the insertion tube 2, and the outer edge of the elastic hole 21 protrudes inward to form a raised ring 26. A detachable locking rod 13 is installed inside the elastic bladder 8. A plug 17 is fixedly connected to the top of the locking rod 13, with the outer end of the plug 17 being a bevel. The elastic force of the reset piece 7 is less than the squeezing force and friction of the rubber block 22, resulting in initial pressure reduction. The device body 1 is in a compressed state, and the locking rod 13 passes through the elastic hole 21 on the rubber block 22. The plug 17 is located at the outer opening of the elastic hole 21 to limit the pressure reducing device body 1 in the compressed state and prevent it from resetting. When in use, the cannula 2 is inserted into the elastic hole 21. Since the diameter of the locking rod 13 is smaller than the diameter of the cannula 2, the locking rod 13 gradually disengages from the elastic hole 21 as the cannula 2 is gradually inserted into the elastic hole 21. The pressure reducing device body 1 is freed from the constraint of the locking rod 13 and gradually expands and attracts. Therefore, when the cannula 2 is connected to the pressure reducing device body 1, it is not necessary to press the gastrointestinal pressure reducing device again for compression, thereby simplifying the operation steps and improving the operation efficiency.

[0049] like Figures 10 to 17As shown, the other end of the rubber block 22 is fixedly connected to an integral connecting piece 23 and a compression piece 25. The compression piece 25 is disposed inside the inner elastic sleeve 24, which can compress the inner elastic sleeve 24, thereby improving the fixing strength of the rubber block 22 in the water inlet pipe 3. An elastic bucket 9 is fixedly connected to the edge of the top opening of the elastic bladder 8. The elastic bucket 9 is fixedly connected to the connecting piece 23 to form an integral whole. The opening of the elastic bucket 9 gradually expands outward to form a sloping wall 10. The opening of the elastic bucket 9 gradually expands outward and faces upward, and is located below the water inlet pipe 3. When the liquid enters the pressure reducing device body 1 through the water inlet pipe 3, the mixture of liquid and residue will first fall onto the elastic bucket 9. The sloping wall 10 facilitates the guidance of the mixture to the elastic bladder 8. When the liquid flows, the residue remains in the elastic bladder 8, and the liquid flows into the pressure reducing device body 1 through the seepage hole 12. This operation can improve the pressure reducing device body 1. The mixed liquid inside the pressure reducing device body 1 is separated, so that the residue is located in the elastic bladder 8 and the liquid is located inside the pressure reducing device body 1. Therefore, when the liquid is discharged through the outlet pipe 30, it will not cause blockage of the outlet pipe 30. An annular pad 11 is fixedly connected to the edge of the opening of the elastic hopper 9. The annular pad 11 is a plane. The pressure reducing device body 1 includes a rigid flat plate, which is located at the upper and lower ends of the pressure reducing device body 1. When the plane on the annular pad 11 is attached to the flat plate at the top of the pressure reducing device body 1, a sealed state is formed. When the elastic bladder 8 at the lower end of the elastic hopper 9 is squeezed and deformed, the residue inside the elastic bladder 8 is squeezed because the elastic hopper 9 at the top is in a sealed state. The squeezed liquid flows into the pressure reducing device body 1 through the seepage hole 12, thereby further diverting the residue. The residue after squeezing is convenient to be removed in the next step.

[0050] like Figures 11 to 13 and Figure 18As shown, the elastic bladder 8 has several leakage holes 12 on its circumferential side, and a slot 29 is provided at the bottom of the elastic bladder 8. The bottom end of the locking rod 13 is fixedly connected to a plug 16 that is threaded to the slot 29. When the plug 16 is screwed to the slot 29, the plug 16 and the elastic bladder 8 are integrated. An annular piece 18 is fixedly connected to the locking rod 13 near the plug 17. The connection between the annular piece 18 and the plug 17 is an arc-shaped protrusion 19. The inlet pipe 3 and the outlet pipe 30 are respectively located on the pressure reducing body 1. Sealing plugs 28 are inserted into the water outlet pipe 30 at both ends of the pressure reducing device body 1. Multiple annular plates 18 are arranged along the same axis. This arrangement allows for clearing of the insertion tube 2 end within the water inlet pipe 3 when the pressure reducing device body 1 is pressed. Before pressing, to prevent backflow of liquid into the gastric tube, the switch on the gastric tube should be closed, and the sealing plugs 28 on the water outlet pipe 30 should be opened. During pressing, the reset plate 7 and the pressure reducing device body 1 are deformed by compression, causing the liquid to flow out. When the body is squeezed outward, the elastic bladder 8 is also deformed by the pressure of the pressure reducing body 1. As the pressure reducing body 1 and the elastic bladder 8 are compressed, their overall height is shortened. The length of the locking rod 13 in the elastic bladder 8 is fixed. The locking rod 13 will extend into the end of the insertion tube 2. When the pressure reducing body 1 is released, all compressed parts are reset, and the locking rod 13 will disengage from the end of the insertion tube 2. By repeatedly pressing, the end of the insertion tube 2 can be unblocked. Furthermore, the sharp design of the outer end of the plug 17 makes it easier for the locking rod 13 to insert into the residue blocking the insertion tube 2. Since the rear end of the plug 17 is provided with several annular plates 18, and the diameter of the several annular plates 18 is smaller than the diameter of the plug 17, the annular plates 18 will not push away the residue. When the plug 17 and the several annular plates 18 are inserted into the residue and then pulled out, the annular plates 18 will carry the residue out of the insertion tube 2. By repeating this process, the end of the insertion tube 2 can be unblocked, making it convenient to clean and reuse the pressure reducing body 1.

[0051] like Figures 12 to 13 and Figure 16As shown, a bracket is fixedly connected to the connection between the locking rod 13 and the insertion rod 16. The bracket includes several annularly arranged first support plates 14, the tops of which are all bent inwards, and each of the first support plates 14 has a through hole 15. The insertion rod 16 at the bottom of the locking rod 13 and the slot 29 are connected by a screw for easy assembly and disassembly, but are not limited to the screw connection method. Other existing structures can be used instead. When it is necessary to remove the locking rod 13, the liquid should be discharged by pressing first, and after the pressure reducing device body 1 is compressed, the locking rod 13 returns to its initial position. Then, rotate the locking rod 13 to disengage it from the slot 29, and then pinch the plug 17 towards... When the locking rod 13 is pulled outward, the inwardly bent end is first compressed inward by the elastic hole 21, which further compresses the residue in the first support plates 14. The squeezed liquid flows out through the gaps between the first support plates 14 and the through holes 15 on the first support plates 14. The residue can be removed by continuing to pull the locking rod 13 outward. The advantages of doing this are: on the one hand, the residue in the elastic bladder 8 can be cleaned, making it convenient to reuse the decompression device body 1; on the other hand, the removed residue is convenient for medical staff to observe and diagnose, solving the problem that the mixed liquid is not conducive to the observation of medical staff.

[0052] like Figure 3 As shown, a pair of support rings 5 ​​are installed inside the pressure reducing device body 1. The pair of support rings 5 ​​and the reset plate 7 are fixedly connected. The pair of support rings 5 ​​are in contact with the inner surfaces of the two planar plates respectively. Several connecting strips 6 are fixedly connected inside each pair of support rings 5. The two ends of the reset plate 7 are fixedly connected to the connecting strips 6 on the pair of support rings 5 ​​respectively. The reset plate 7 is located between the pair of support rings 5 ​​to form a whole.

[0053] The working principle of the technical solution provided by the present invention is as follows: First, the intubation tube 2 is closed, then one end of the intubation tube 2 is connected to the external gastric tube, and then the other end of the intubation tube 2 is connected to the water inlet tube 3 on the decompression device body 1. When connecting, the intubation tube 2 is inserted into the elastic hole 21. Since the diameter of the locking rod 13 is smaller than the diameter of the intubation tube 2, when the intubation tube 2 is gradually inserted into the elastic hole 21, the locking rod 13 gradually disengages from the contact with the elastic hole 21, and the decompression device body 1 is released from the constraint of the locking rod 13 and gradually expands and attracts.

[0054] When clearing the obstruction of the intubation tube 2, apply pressure. Before applying pressure, to prevent fluid from flowing back into the gastric tube, close the valve on the gastric tube and open the sealing plug 28 on the outlet tube 30. When applying pressure, the reset plate 7 and the pressure reducing device body 1 are compressed and deformed, squeezing the fluid outward. At the same time, the elastic bladder 8 is also compressed by the pressure reducing device body 1 and deforms. Due to the compression of the pressure reducing device body 1 and the elastic bladder 8, their overall height is shortened. The length of the locking rod 13 in the elastic bladder 8 is fixed, and the locking rod 13 will extend into the end of the intubation tube 2. When the pressure reducing device body 1 is released, the fluid... The compressed components are reset, and the locking lever 13 will disengage from the end of the insertion tube 2. Repeated pressing can clear the end of the insertion tube 2. Furthermore, the sharp design of the outer end of the plug 17 facilitates the insertion of the locking lever 13 into the residue blocking the insertion tube 2. Since the rear end of the plug 17 is provided with several annular plates 18, and the diameter of the annular plates 18 is smaller than the diameter of the plug 17, the annular plates 18 will not push away the residue. When the plug 17 and the annular plates 18 are inserted into the residue and then pulled out, the annular plates 18 will carry the residue out of the insertion tube 2, and this process is repeated.

[0055] When removing the residue, follow the steps above to first press out the liquid. After the pressure reducing device body 1 is compressed, the locking rod 13 returns to its initial position. Then, rotate the locking rod 13 to disengage it from the slot 29. Then, pinch the plug 17 and pull it outward. When pulling out the locking rod 13, the inwardly bent end is first squeezed inward by the elastic hole 21, which further compresses the residue in the first support plates 14. The squeezed liquid flows out through the gaps between the first support plates 14 and the through holes 15 on the first support plates 14. Continue to pull out the locking rod 13 to remove the residue. The advantages of doing this are: on the one hand, it can clean the residue in the elastic bladder 8, making it convenient to reuse the pressure reducing device body 1; on the other hand, the removed residue is convenient for medical staff to observe and diagnose, solving the problem that the liquid in the mixed state is not conducive to observation.
