Description

Technical Field

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

[0002] Gastrointestinal decompression involves inserting a gastric tube through the mouth or nose, connecting it to a disposable gastrointestinal decompression device. Under negative pressure and siphon effect, the stomach contents are drained from the patient's body. This method removes gas or fluid from the gastrointestinal tract, reducing pressure, decreasing gastrointestinal distension, improving blood circulation in the gastrointestinal wall, and promoting wound healing and functional recovery. Specifically, it aims to: relieve or alleviate symptoms caused by intestinal obstruction; prepare for gastrointestinal surgery to reduce gastrointestinal distension; and remove gas and stomach contents postoperatively to reduce abdominal distension, decrease suture tension and wound pain, promote wound healing, improve blood circulation in the gastrointestinal wall, and promote the recovery of digestive function.

[0003] Existing gastrointestinal decompression devices are prone to causing blockages in the gastrointestinal tract when suctioning out gas and fluids or when the contents are large and viscous. Although existing technologies include flushing tubes for this purpose, the flushing fluid inevitably pushes back the contents that were blocking the tract into the patient's body. This causes two problems: firstly, the backflow of the flushing fluid and contents creates excessive pressure in the gastrointestinal tract, leading to patient discomfort; secondly, some patients may have harmful gases or fluids in their gastrointestinal tract. During suction, these harmful gases or fluids may remain on the inner wall of the tract. When flushing fluid is used to clean the tract, these harmful substances are also pushed back into the patient's body, causing further harm. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide a gastrointestinal decompression device that can prevent the flushing fluid and flushed contents from flowing back into the patient's gastrointestinal tract during the flushing process, thereby reducing the impact and discomfort on the patient's stomach and intestines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gastrointestinal decompression device includes a suction mechanism inserted into the patient's gastrointestinal tract via the patient's nasal cavity or oral cavity, a cleaning mechanism connected to the suction mechanism at one end outside the patient's body, and an adjustment mechanism sleeved on the outside of the suction mechanism for adjusting the suction rate. The suction mechanism includes a contents collection tank, a gastrointestinal tube inserted into the patient's gastrointestinal tract via the patient's nasal cavity or oral cavity and connected to the contents collection tank at its outlet, a suction pump connected to the gastrointestinal tube, and a device fixed to the end of the gastrointestinal tube at its inlet. The system includes a first one-way valve that allows gas or liquid to flow unidirectionally from the patient's gastrointestinal tract into the gastrointestinal tube; the cleaning mechanism includes an inlet pipe connected to the end of the gastrointestinal tube located outside the patient's body, a pump connected to the inlet pipe, and a storage tank connected to the inlet end of the inlet pipe; the gastrointestinal tube has a cavity circumferentially formed inside its wall, and several outlet side holes are circumferentially formed on the inner surface of the inlet end of the gastrointestinal tube; the outlet end of the inlet pipe passes through the outer wall of the gastrointestinal tube and communicates with the cavity; each outlet side hole communicates with the cavity.

[0007] More preferably, the adjustment mechanism includes a mounting seat fitted onto the end of the gastrointestinal tube located outside the patient's body, a slide rail inclinedly embedded on one side of the mounting seat along the extension direction of the gastrointestinal tube, a connecting rod slidably disposed within the slide rail, and a pressure roller rotatably fitted onto the outside of the connecting rod and abutting against the wall of the gastrointestinal tube.

[0008] More preferably, the gastrointestinal tube is further fitted with an auxiliary fixation assembly; the auxiliary fixation assembly includes a collar fitted on the outside of the end of the gastrointestinal tube located outside the patient and in an interference fit with the gastrointestinal tube, a pair of straps symmetrically fixed on both sides of the collar, and a quick-release sub-assembly located between the two straps; the quick-release sub-assembly includes a first connecting buckle fixed to the end of one of the straps and a second connecting buckle fixed to the end of the other strap and inserted into the first connecting buckle.

[0009] More preferably, the top of the contents collection box is provided with an air vent, and a sealing plug is fixed inside the air vent to allow gas to flow unidirectionally from inside the contents collection box to the outside.

[0010] More preferably, each liquid outlet side hole is equipped with a second one-way valve that allows liquid to flow unidirectionally from the cavity into the gastrointestinal tract.

[0011] This utility model has the following beneficial effects:

[0012] 1. In the case of gastrointestinal obstruction, this utility model uses a suction pump to inject the cleaning solution in the storage tank into the gastrointestinal tube through the inlet pipe, flushing and aspirating the obstructed contents. The impact force of the inclined tube is used to clear the obstruction. During the clearing process, a first one-way valve is fixed at the inlet end of the gastrointestinal tube, preventing the flushing solution and the obstructed gastrointestinal contents from flowing back into the patient's gastrointestinal tract. This avoids the situation where the flushing solution and contents flow back into the gastrointestinal tract, causing excessive pressure and discomfort to the patient. It also avoids the situation where harmful substances remaining in the gastrointestinal tube are flushed back into the patient's body when the flushing solution is used to clean the gastrointestinal tube, thus minimizing the risk of the patient being harmed by these harmful substances again.

[0013] 2. This utility model pushes the pressure roller to make the connecting rod slide along the slide rail. Since the slide rail is inclined, the pressure roller will cause different degrees of compression on the gastrointestinal tube during the sliding process, thereby changing the flow rate of liquid and gas in the gastrointestinal tube, so as to avoid the patient's discomfort caused by the excessively fast suction rate, and also to maximize the suction rate.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] A gastrointestinal decompression device includes a suction mechanism 1 inserted into the patient's gastrointestinal tract via the patient's nasal cavity or oral cavity, a cleaning mechanism 2 connected to the suction mechanism 1 at one end outside the patient's body, and an adjustment mechanism 3 fitted outside the suction mechanism 1 to adjust the suction rate of the suction mechanism 1. The suction mechanism 1 includes a contents collection tank 12, a gastrointestinal tube 11 inserted into the patient's gastrointestinal tract via the patient's nasal cavity or oral cavity and connected to the contents collection tank 12 at its outlet, a suction pump 13 connected to the gastrointestinal tube 11, and a pump fixed at the end of the gastrointestinal tube 11 that allows gas or liquid to be drawn from the patient's body. A first one-way valve 14 allows unidirectional flow of gastrointestinal contents into the gastrointestinal tube 11; the cleaning mechanism 2 includes an inlet pipe 21 connected to the end of the gastrointestinal tube 11 located outside the patient, a pump 22 connected to the inlet pipe 21, and a storage tank 23 connected to the inlet end of the inlet pipe 21; a cavity 111 is formed around the inside of the tube wall of the gastrointestinal tube 11, and several outlet side holes 112 are formed around the inner surface of the inlet end of the gastrointestinal tube 11; the outlet end of the inlet pipe 21 passes through the outer wall of the gastrointestinal tube 11 and connects to the cavity 111; each outlet side hole 112 is connected to the cavity 111.

[0022] When the gastrointestinal tract 11 is blocked, the cleaning solution in the storage tank 23 is injected into the gastrointestinal tract 11 through the inlet pipe 21 by the suction pump 22. The contents blocking the gastrointestinal tract 11 are flushed and aspirated. The impact force of the inclined pipe is used to clear the gastrointestinal tract 11. During the clearing process, the first one-way valve 14 is fixed at the inlet end of the gastrointestinal tract 11, so that the flushing solution and the blocked gastrointestinal contents cannot flow back into the patient's gastrointestinal tract. On the one hand, it is necessary to avoid the situation where the flushing solution and contents flow back into the gastrointestinal tract and cause excessive pressure in the gastrointestinal tract, which may cause discomfort to the patient. On the other hand, it is also necessary to avoid the situation where harmful substances remaining in the gastrointestinal tract are flushed back into the patient's body when the flushing solution is used to clean the gastrointestinal tract, thereby minimizing the risk of the patient being harmed by these harmful substances again.

[0023] As a possible implementation of this solution, preferably, the adjustment mechanism 3 includes a mounting base 31 sleeved onto the end of the gastrointestinal tube 11 located outside the patient's body, a slide rail 32 inclinedly embedded on one side of the mounting base 31 along the extension direction of the gastrointestinal tube 11, a connecting rod 33 slidably disposed within the slide rail 32, and a pressure roller 34 rotatably sleeved outside the connecting rod 33 and abutting against the wall of the gastrointestinal tube 11; by pushing the pressure roller 34, the connecting rod 33 slides along the slide rail 32. Since the slide rail 32 is inclined, the pressure roller 34 will cause different degrees of compression on the gastrointestinal tube 11 during the sliding process, thereby changing the flow rate of liquid and gas in the gastrointestinal tube 11, so as to avoid the patient's discomfort caused by the excessively fast suction rate as much as possible, and also to increase the suction rate as much as possible.

[0024] As a possible implementation of this solution, preferably, the gastrointestinal tube 11 is further fitted with an auxiliary fixation component 4. The auxiliary fixation component 4 includes a collar 41 fitted on the outside of the end of the gastrointestinal tube 11 located outside the patient and in an interference fit with the gastrointestinal tube 11, a pair of straps 42 symmetrically fixed on both sides of the collar 41, and a quick-release sub-component 43 located between the two straps 42. The quick-release sub-component 43 includes a first connecting buckle 431 fixed to the end of one of the straps 42 and a second connecting buckle 432 fixed to the end of the other strap and inserted into the first connecting buckle 431. Through the cooperation of the first connecting buckle 431 and the second connecting buckle 432, the two straps 42 can fix the gastrointestinal tube 11 to the patient's head, thereby minimizing the risk of the gastrointestinal tube 11 detaching from the patient's nose, mouth, and oral cavity, thereby increasing the rate of aspiration of the patient's gastrointestinal contents.

[0025] As a possible implementation of this solution, preferably, the top of the contents collection box 12 is provided with a vent 121, and a sealing plug 122 is provided inside the vent 121; the gas inside the contents collection box 121 can be released through the vent 121.

[0026] As a possible implementation of this solution, preferably, each outlet side hole 112 is fixedly provided with a second one-way valve 113 that allows liquid to flow unidirectionally from the cavity 111 into the gastrointestinal tube 11; the setting of the second one-way valve 113 can prevent the contents of the patient's gastrointestinal tract from flowing into the cavity 111, the inlet pipe 21, the suction pump 22 or even the storage tank 23 when the contents of the gastrointestinal tract are aspirated, thereby avoiding contamination of the cleaning solution by the gastrointestinal contents.

[0027] The working principle of this device is as follows:

[0028] When it is necessary to aspirate the patient's contents, the contents of the patient's gastrointestinal tract can be drawn through the gastrointestinal tube 11 to the contents collection tank 12 for collection by the suction pump 13. When the gastrointestinal tube 11 is blocked, the flushing fluid in the storage tank 23 is drawn through the inlet pipe 21 and the cavity 111 and then through the outlet side hole 112 into the gastrointestinal tube 11 by the suction pump 22. Under the delivery of the suction pump 22 and the suction of the suction pump 13, the flushing fluid flowing into the gastrointestinal tube 11 is accelerated to flush through the gastrointestinal tube 11 to clear the blocked contents in the gastrointestinal tube 11.

[0029] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
