Description

Technical Field

[0001] The invention relates to the technical field of gastrointestinal decompression, and in particular to a gastrointestinal decompression device. Background Art

[0002] A gastrointestinal decompressor is a medical device that uses the principle of negative pressure suction to absorb gas and liquid accumulated in the gastrointestinal tract to reduce the pressure in the gastrointestinal tract, improve blood circulation in the gastrointestinal wall, and promote wound healing and gastrointestinal function recovery. The outer skin of a gastrointestinal decompressor is usually made of plastic. A gastrointestinal decompressor made of this material can be flattened, and the gastrointestinal decompressor can be expanded through a built-in elastic component. A water inlet pipe and a water outlet pipe are usually provided on the gastrointestinal decompressor. The water inlet pipe is connected to the gastric tube. When draining water, the water outlet pipe is opened to drain water for reuse.

[0003] The existing gastrointestinal decompression device is usually packed in a bag after being compressed. When it is used, the bag needs to be opened. When inserting the tube, the tube mouth of the gastrointestinal decompression device needs to be opened. At this time, the gastrointestinal decompression device will expand. Then, one hand presses the gastrointestinal decompression device to compress it, and the other hand inserts the cannula into the tube mouth of the gastrointestinal decompression device. However, when pressing the gastrointestinal decompression device again, in order to expel air as much as possible, the gastrointestinal decompression device needs to be placed on a flat surface and then pressed, which is cumbersome and affects the efficiency. In addition, the liquid sucked into the gastrointestinal decompression device may contain food residues. Before the food residues follow the liquid into the gastrointestinal decompression device, they are easy to be blocked at the end outlet of the cannula, affecting the suction effect. After the residue follows the liquid into the gastrointestinal decompression device, when squeezing out the liquid from the gastrointestinal decompression device, the food residue is easy to block the outlet pipe. Generally, this is done by repeatedly squeezing the blocked part of the pipe joint, but the clearing effect is limited. If it cannot be cleared, the gastrointestinal decompression device can only be replaced, resulting in equipment waste; and in some clinical situations, it is necessary to check the food residue in the gastrointestinal decompression device, and in some cases, the residue needs to be observed and diagnosed, which helps medical staff evaluate the patient's condition and treatment effect, but because the residue and liquid in the decompression device are in a mixed state, only the liquid can be observed from the outside of the gastrointestinal decompression device, and the residue cannot be effectively observed and diagnosed. Therefore, the present application provides a gastrointestinal decompression device to meet the 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 that the existing gastrointestinal decompression device is complicated to operate and difficult to effectively clear blockage during connection, and is not conducive to medical staff's observation and diagnosis of residues.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A gastrointestinal decompressor comprises a decompressor body and a cannula, wherein a water inlet pipe and a water outlet pipe are fixedly connected to the decompressor body, and the water inlet pipe is plugged into and matched with the cannula; and further comprises a processing component for opening or closing the ventilation state of the decompressor body and for processing liquid residue entering the decompressor body, wherein the processing component is located in the decompressor body and connected to the water inlet pipe.

[0007] The processing component includes an elastic bag and a reset sheet and a plug-in component located in the water inlet pipe, the plug-in component includes a rubber block, one end of the rubber block is fixedly connected with an integral outer elastic sleeve and an inner elastic sleeve, a accommodating area is formed between the outer elastic sleeve and the inner elastic sleeve, the outer elastic sleeve is wrapped around the outer ring of the plug-in component, and the other end of the rubber block is fixedly connected with an integral connecting sheet and an extrusion sheet; an elastic hole is opened in the rubber block, the elastic hole and the plug-in tube are plug-fitted, a detachable locking rod is installed in the elastic bag, the top end of the locking rod is fixedly connected with a plug, and the outer end edge of the elastic hole protrudes inward to form a convex ring.

[0008] Optionally, a plurality of seepage holes are provided on the side surfaces of the elastic sac, a slot is provided on the bottom of the elastic sac, and the bottom end of the locking rod is fixedly connected to an insertion rod threadedly fixed to the slot; the locking rod is fixedly connected to an annular sheet near the plug, and the connection between the annular sheet and the plug is an arc-shaped protrusion.

[0009] Optionally, a bracket is fixedly connected to the connection between the locking rod and the insertion rod, and the bracket includes a plurality of first support plates arranged in an annular shape, the top ends of the plurality of first support plates are bent inwards, and the plurality of first support plates are provided with through holes.

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

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

[0012] Optionally, the pressure reducer body comprises a hard planar plate body, and the planar plate body is respectively located at the upper and lower ends of the pressure reducer body.

[0013] Optionally, a pair of support rings are installed in the pressure reducer body, the two ends of the reset plate are respectively fixed to the pair of support rings, the pair of support rings are respectively in contact with the inner surfaces of the two planar plates, and a plurality of connecting strips are fixedly connected to the pair of support rings.

[0014] Optionally, the water inlet pipe and the water outlet pipe are respectively located at the upper and lower ends of the pressure reducer body, and a sealing plug is inserted into the water 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 scheme, by setting the 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, and the plug is located at the opening outside the elastic hole for limiting, so as to prevent the pressure reducer body in the compressed state from resetting, thereby realizing the sealing of 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 setting the elastic bag, when the liquid enters the pressure reducer body through the water inlet pipe, the mixed liquid formed by the liquid and the residue will first fall on the elastic bucket. The slope wall is conducive to guiding the mixed liquid into the elastic bag. When the liquid flows, the residue remains in the elastic bag, and the liquid flows into the pressure reducer body through the seepage hole. This operation can separate the mixed liquid entering the pressure reducer body, so that the residue is located in the elastic bag and the liquid is located in the pressure reducer body. Therefore, when the liquid is discharged through the water outlet pipe later, it will not cause the problem of clogging the water outlet pipe; by setting the elastic bucket, since the elastic bucket at the top and the flat panel body are matched in a sealed state, the residue in the elastic bag is squeezed and the squeezed liquid flows into the pressure reducer body through the seepage hole, thereby further diverting the residue, and the residue after the squeezing process is convenient for the next step to be taken out.

[0018] By setting a locking rod, in addition to maintaining the compression state of the pressure reducer body, the locking rod can repeatedly extend into the end of the cannula to achieve the effect of unblocking the cannula end: the sharp design of the outer end of the plug is conducive to the locking rod inserting into the residue blocked in the cannula, and because a plurality of annular sheets are provided at the rear end of the plug, and the diameters of the plurality of annular sheets are smaller than the diameter of the plug, the annular sheets will not push the residue away. When the plug and the plurality of annular sheets are inserted into the residue and then pulled out, the annular sheets will bring the residue out of the cannula. This can be repeated to achieve the effect of unblocking the cannula end, thereby facilitating the cleaning and reuse of the gastrointestinal pressure reducer.

[0019] By arranging a plurality of first support sheets on the locking rod, when the locking rod is pulled out, the end thereof bent inwardly is first squeezed inward by the elastic hole, so that the residue in the plurality of first support sheets is further squeezed, and the squeezed liquid flows out through the gaps between the plurality of first support sheets and the through holes on the plurality of first support sheets, and the residue can be removed by continuing to pull the locking rod outward. The advantages of this are: on the one hand, the residue in the elastic bag can be cleaned, so that it is convenient to use the pressure reducer body again; on the other hand, the removed residue is convenient for medical staff to observe and diagnose, which solves the problem that the liquid in a mixed state is not conducive to observation. In summary, the present invention has a clever structure and systematically optimizes the entire operation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] like Figures 1 to 19As shown, an embodiment of the present invention provides a gastrointestinal pressure reducer, including a pressure reducer body 1 and a cannula 2. The cannula 2 is a hose in the prior art, and both ends of the cannula are provided with plastic plugs. The pressure reducer body 1 is fixedly connected with a water inlet pipe 3 and a water outlet pipe 30, and the water inlet pipe 3 is plugged and matched with the cannula 2. The pressure reducer body 1 is also provided with an exhaust pipe, and a rubber plug is inserted in the exhaust pipe. When necessary, the rubber plug is pulled out to perform exhaust operation; it also includes a processing component for opening or closing the ventilation state of the pressure reducer body 1 and for processing liquid residues entering the pressure reducer body 1. The processing component is located in the pressure reducer body 1 and is connected to the water inlet pipe 3; the processing The assembly includes an elastic bag 8, a reset sheet 7, and a plug-in component 4 located in the water inlet pipe 3. From top to bottom, they are the plug-in component 4 and the elastic bag 8. The reset sheet 7 is located on the periphery of the plug-in component 4 and the elastic bag 8. The plug-in component 4 includes a rubber block 22. One end of the rubber block 22 is fixedly connected with an integrated 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 plug-in component 4 is inserted into the water inlet pipe 3, the outer elastic sleeve 20 is wrapped around the outer ring of the plug-in component 4 to further reinforce it. The plug-in component 4 is used to prevent the plug-in component 4 from being dislocated; the pressure reducer body 1 is in a compressed state when taken out of the packaging bag. When in use, the insert tube 2 is inserted into the elastic hole 21 on the rubber block 22, and the elastic rubber allows the elastic hole 21 to wrap the insert tube 2; the rubber block 22 is provided with an elastic hole 21, the elastic hole 21 and the insert tube 2 are plugged in, and the outer edge of the elastic hole 21 bulges inward to form a convex ring 26; a detachable locking rod 13 is installed in the elastic bag 8, and a plug 17 is fixedly connected to the top of the locking rod 13, wherein the outer end of the plug 17 is an inclined surface, and the elastic force of the reset sheet 7 is less than the extrusion force and friction force of the rubber block 22, and the pressure is reduced in the initial state. The pressure reducer 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 for limiting to prevent the pressure reducer body 1 in the compressed state 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 breaks away from the contact with the elastic hole 21 when the cannula 2 is gradually inserted into the elastic hole 21. The pressure reducer body 1 breaks away from the constraint of the locking rod 13 and gradually expands and attracts. Therefore, when the cannula 2 is connected to the pressure reducer body 1, there is no need to press the gastrointestinal pressure reducer 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 with an integrated connecting piece 23 and an extruding piece 25. The extruding piece 25 is arranged in the inner elastic sleeve 24 and can squeeze the inner elastic sleeve 24, which is beneficial to improve the fixing strength of the rubber block 22 in the water inlet pipe 3. The edge of the top opening of the elastic capsule 8 is fixedly connected with an elastic bucket 9. The elastic bucket 9 is fixedly connected to the connecting piece 23 to form a whole. The opening of the elastic bucket 9 gradually expands outward to form a slope wall 10, wherein the opening of the elastic bucket 9 gradually expands outward to face upward and is located below the water inlet pipe 3. When the liquid enters the pressure reducer body 1 through the water inlet pipe 3, the mixed liquid formed by the liquid and the residue will first fall on the elastic bucket 9. The slope wall 10 is beneficial to diverting the mixed liquid into the elastic capsule 8. When the liquid flows, the residue remains in the elastic capsule 8, and the liquid flows into the pressure reducer body 1 through the seepage hole 12. This operation can The mixed liquid entering the pressure reducer body 1 is separated, so that the residue is located in the elastic bag 8 and the liquid is located in the pressure reducer body 1, so that the liquid will not cause the problem of clogging the water outlet pipe 30 when it is discharged through the water outlet pipe 30 later; the opening edge of the elastic bucket 9 is fixedly connected with an annular pad 11, wherein the annular pad 11 is a plane, and the pressure reducer body 1 includes a hard plane plate body, which is respectively located at the upper and lower ends of the pressure reducer body 1. When the plane on the annular pad 11 fits the plane plate body at the top of the pressure reducer body 1, a sealed state is formed, and when the elastic bag 8 at the lower end of the elastic bucket 9 is squeezed and deformed, since the elastic bucket 9 at its top is in a sealed state, the residue in the elastic bag 8 is squeezed, and the squeezed liquid flows into the pressure reducer body 1 through the seepage hole 12, thereby further diverting the residue, and the residue after the squeezing process is convenient for the next step to be taken out.

[0050] like Figures 11 to 13 and Fig.18As shown, the elastic bag 8 is provided with a plurality of seepage holes 12 on the side surface thereof, a slot 29 is provided on the bottom of the elastic bag 8, and a plug rod 16 is fixedly connected to the bottom end of the locking rod 13 with a threaded connection to the slot 29. When the plug rod 16 is threadedly fixed to the slot 29, the plug rod 16 and the elastic bag 8 are integrated; the locking rod 13 is fixedly connected to a ring sheet 18 near the plug 17, and the connection between the ring sheet 18 and the plug 17 is a curved protrusion 19. The water inlet pipe 3 and the water outlet pipe 30 are respectively located on the pressure reducer body 1 The upper and lower ends of the pressure reducer body 1 are plugged with a sealing plug 28 in the water inlet pipe 3 at the lower end thereof; wherein the annular sheet 18 is multiple, and the multiple annular sheets 18 are arranged on the same axis. The advantage of this is that when the pressure reducer body 1 is pressed, the end of the cannula 2 located in the water inlet pipe 3 can be unblocked. Before pressing, in order to prevent the liquid from flowing back into the stomach tube, the switch on the stomach tube should be closed, and the sealing plug 28 on the water outlet pipe 30 should be opened. When pressed, the reset sheet 7 and the pressure reducer body 1 are squeezed and deformed to release the liquid. The body is squeezed outward, and the elastic bag 8 is squeezed by the pressure reducer body 1 and deformed. Since the pressure reducer body 1 and the elastic bag 8 are squeezed and compressed, their overall height is shortened, and the length of the locking rod 13 in the elastic bag 8 is fixed, and the locking rod 13 will extend into the end of the cannula 2. When the pressure reducer body 1 is released, all compressed parts are reset, and the locking rod 13 will be separated from the end of the cannula 2. Repeated pressing can achieve the effect of unblocking the end of the cannula 2: and the sharp design of the outer end of the plug 17 is conducive to the insertion of the locking rod 13 into the residue blocked in the cannula 2. Since the rear end of the plug 17 is provided with a plurality of annular sheets 18, and the diameter of the plurality of annular sheets 18 is smaller than the diameter of the plug 17, the annular sheets 18 will not push the residue away. When the plug 17 and the plurality of annular sheets 18 are inserted into the residue and then pulled out, the annular sheets 18 will bring the residue out of the cannula 2. Repeatedly, the effect of unblocking the end of the cannula 2 can be achieved, and the pressure reducer body 1 is convenient to clean and reuse.

[0051] like Figure 12 to Figure 13 and Fig.16As shown, the locking rod 13 and the insertion rod 16 are fixedly connected to a bracket at the connection point, and the bracket includes a plurality of first support sheets 14 arranged in an annular manner, the top ends of the plurality of first support sheets 14 are bent inward, and a plurality of first support sheets 14 are provided with through holes 15, wherein the insertion rod 16 and the slot 29 at the bottom end of the locking rod 13 are screwed together for convenient assembly and disassembly, but are not limited to the screwing method, and other structures of the prior art can be used instead. When the locking rod 13 needs to be taken out, the liquid should be pressed and discharged according to the above steps, and the locking rod 13 is reset to the initial position after the pressure reducer body 1 is compressed, and then the locking rod 13 is rotated to disengage from the slot 29, and then the plug 17 is pinched to move toward When the locking rod 13 is pulled out, the end thereof bent inwardly is first squeezed by the elastic hole 21 and compressed inwardly, so that the residue in the first support sheets 14 is further squeezed, and the squeezed liquid flows out through the gaps between the first support sheets 14 and the through holes 15 on the first support sheets 14. The locking rod 13 is continued to be pulled out to remove the residue. The advantages of doing so are: on the one hand, the residue in the elastic bag 8 can be cleaned, which is convenient for reusing the pressure reducer body 1; on the other hand, the removed residue is convenient for medical staff to observe and diagnose, which solves the problem that the liquid in a mixed state is not conducive to medical staff's observation.

[0052] like Figure 3 As shown, a pair of support rings 5 ​​are installed in the pressure reducer body 1, and the pair of support rings 5 ​​are fixedly connected to the reset plate 7. The pair of support rings 5 ​​are respectively in contact with the inner surfaces of the two planar plates. A plurality of connecting strips 6 are fixedly connected in the pair of support rings 5, and the two ends of the reset plate 7 are respectively fixedly connected to the connecting strips 6 on the pair of support rings 5. 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 cannula 2 is closed, and then one end of the cannula 2 is connected to the external stomach tube, and then the other end of the cannula 2 is connected to the water inlet pipe 3 on the pressure reducer body 1. When connecting, 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, when the cannula 2 is gradually inserted into the elastic hole 21, the locking rod 13 is gradually separated from the contact with the elastic hole 21, and the pressure reducer body 1 is separated from the constraint of the locking rod 13 and gradually expands and attracts.

[0054] When clearing the plug 2, press. Before pressing, in order to prevent the liquid from flowing back into the gastric tube, the switch on the gastric tube should be turned off, and the sealing plug 28 on the outlet pipe 30 should be opened. When pressing, the reset sheet 7 and the reducer body 1 are squeezed and deformed to squeeze the liquid outward. At the same time, the elastic bag 8 is squeezed by the reducer body 1 and deformed. Since the reducer body 1 and the elastic bag 8 are squeezed and compressed, their overall height is shortened, and the length of the locking rod 13 in the elastic bag 8 is fixed. The locking rod 13 will extend into the end of the plug 2. When the reducer body 1 is released, the The compressed parts are reset, and the locking rod 13 will be out of the end of the cannula 2. Repeated pressing can achieve the effect of unblocking the end of the cannula 2. In addition, the sharp design of the outer end of the plug 17 is conducive to the insertion of the locking rod 13 into the residue blocked in the cannula 2. Since a plurality of annular sheets 18 are provided at the rear end of the plug 17, and the diameter of the plurality of annular sheets 18 is smaller than the diameter of the plug 17, the annular sheets 18 will not push the residue away. When the plug 17 and the plurality of annular sheets 18 are inserted into the residue and then pulled out, the annular sheets 18 will bring the residue out of the cannula 2, and this is repeated.

[0055] When removing the residue, press and discharge the liquid according to the above steps. After the pressure reducer body 1 is compressed, the locking rod 13 is reset to the initial position. Then, the locking rod 13 is rotated to disengage from the slot 29. Then, the plug 17 is pinched and pulled out. When pulling out the locking rod 13, the end bent inwardly is first squeezed by the elastic hole 21 and compressed inwardly, so that the residue in the first support sheets 14 is further squeezed. The squeezed liquid flows out through the gaps between the first support sheets 14 and the through holes 15 on the first support sheets 14. The locking rod 13 is continued to be pulled out to remove the residue. The advantages of doing this are: on the one hand, the residue in the elastic bag 8 can be cleaned, which is convenient for reusing the pressure reducer body 1. On the other hand, the removed residue is convenient for medical staff to observe and diagnose, which solves the problem that the liquid in a mixed state is not conducive to observation.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.
