Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anti-reflux drainage device for an intestinal obstruction catheter. Background Art

[0002] Intestinal obstruction is a serious condition with symptoms including abdominal pain, vomiting, diarrhea, and even complications such as intestinal perforation in severe cases. An intestinal obstruction catheter is used to drain fluid and gas accumulated in the intestines, thereby relieving intestinal pressure and preventing further damage, thereby alleviating the patient's pain.

[0003] However, during the drainage process, if there are situations such as failure of the negative pressure suction device, blockage of the drainage tube, and improper placement of the drainage tube, the intestinal contents in the drainage tube may flow back. The reflux will enter the proximal intestinal cavity, aggravate obstruction or cause infection.

[0004] Therefore, how to design an intestinal obstruction catheter anti-reflux drainage device that can solve the above technical problems is a technical problem that needs to be solved. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide an anti-reflux drainage device for intestinal obstruction catheters, which solves the problem that intestinal contents in the drainage tube are prone to reflux during existing intestinal obstruction drainage and the operation of solving the reflux is cumbersome.

[0006] To achieve the above-mentioned object, the present invention adopts the following technical solution: comprising a three-way connector, a first drainage catheter connected to one end port of the three-way connector, a spiral drainage tube connected to one end port of the three-way connector, a one-way valve connected to one end port of the three-way connector, and a multi-chamber collection bag connected to the spiral drainage tube;

[0007] The inner wall of the first drainage catheter is provided with a plurality of elastic valves along its circumference. The valves have a pair of side edges and a lower edge. The lower edge of the valve is fixedly connected to the inner wall of the first drainage catheter. The outer walls of the valves between adjacent valves are against each other and in a closed state.

[0008] Furthermore, the multi-chamber collecting bag includes a first bag body, a second bag body arranged on one side of the first bag body and connected to the first bag body, a first conduit arranged at the top of the first bag body, a first liquid outlet pipe arranged at the bottom of the first bag body, a second liquid outlet pipe arranged at the bottom of the second bag body, and a first drain valve clamped on the first liquid outlet pipe and the second liquid outlet pipe; a net for separating intestinal contents is fixed at the connection between the first bag body and the second bag body.

[0009] Furthermore, the first conduit is clamped with a second drain valve.

[0010] Furthermore, scale lines are provided on the outer side walls of the first bag body and the second bag body.

[0011] Furthermore, the number of the valves is four to eight.

[0012] The present invention has the following beneficial effects:

[0013] 1-The present invention provides a first drainage tube, and by arranging a plurality of elastic valves in the first drainage tube, when the drainage fluid flows from the human body toward the first drainage tube, the outer wall of the valve is squeezed, causing a pair of side edges of the valve to move toward the inner wall of the tube, and the radial gap between the valves increases, and the valves are in an open state. When backflow occurs, the inner wall of the valve is pushed by the pressure of the drainage fluid to push the side edges of the valve to move toward the central axis of the drainage tube and stick together. Under the action of the interaction force between the plurality of valves and the elastic force of the valves themselves, the valves are in a closed state, and the drainage fluid is prevented from flowing back.

[0014] 2-The present invention provides a multi-cavity collection bag to facilitate the separation of drainage fluid and intestinal contents, making it easier for medical staff to conduct subsequent quantitative evaluations.

[0015] 3- The present invention provides a spiral drainage tube to further prevent backflow of drainage fluid by increasing the flow resistance of the drainage fluid.

[0016] 4-The present invention is provided with a three-way connector, which facilitates medical staff to disassemble the spiral drainage tube and the multi-cavity collection bag, clean the drainage tube or replace the multi-cavity collection bag when backflow occurs in the first drainage tube or drainage stops in the first drainage tube, thereby improving drainage efficiency.

[0026] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0027] See also Figure 1-3 As shown, the solution includes a three-way connector 1, a first drainage catheter 2 connected to one end of the three-way connector 1, a spiral drainage tube 3 connected to one end of the three-way connector 1, a one-way valve 5 connected to one end of the three-way connector 1, and a multi-chamber collection bag 4 connected to the spiral drainage tube 3; the above-mentioned valve 21 is supported by an elastic matrix with good elasticity.

[0028] A drainage bag or other container is connected to the outside through the one-way valve 5, which makes it convenient for medical staff to disassemble and spiral the drainage tube 3 or replace the multi-chamber collection bag 4 for drainage.

[0029] The inner wall of the first drainage catheter 2 is provided with a plurality of elastic valves 21 along its circumference. The valves 21 have a pair of side edges and a lower edge. The lower edge of the valve 21 is fixedly connected to the inner wall of the first drainage catheter 2. The outer walls of the valves 21 between adjacent valves 21 are pressed against each other to form a closed state.

[0030] Furthermore, in this embodiment, the multi-chamber collection bag 4 includes a first bag body 41, a second bag body 42 provided on one side of the first bag body 41 and connected to the first bag body 41, a first conduit 43 provided at the top of the first bag body 41, a first liquid outlet pipe 44 provided at the bottom of the first bag body 41, a second liquid outlet pipe 45 provided at the bottom of the second bag body 42, and a first drain valve 46 clamped on the first liquid outlet pipe 44 and the second liquid outlet pipe 45; a mesh 47 for separating intestinal contents is fixedly provided at the connection between the first bag body 41 and the second bag body 42. When in use, the first conduit 43 is connected to the liquid outlet end of the spiral drainage tube 3, the second drain valve 431 is opened to allow drainage liquid to enter the first bag body 41, and the drainage liquid passes through the mesh 47 from the first bag body 41 to the second bag body 42. The intestinal contents are blocked by the mesh 47 and accumulated in the first bag body 41. The drainage liquid and intestinal contents can be easily removed by medical staff through the first liquid outlet pipe 44 and the second liquid outlet pipe 45, which is convenient for quantitative evaluation.

[0031] Furthermore, the first conduit 43 is provided with a second drain valve 431 .

[0032] Furthermore, scale lines 48 are provided on the outer side walls of the first bag body 41 and the second bag body 42 .

[0033] Furthermore, the number of the valves 21 is four to eight.

[0034] The working principle is roughly as follows:

[0035] The outer walls of the valves 21 are pressed against each other. When the drainage fluid flows smoothly from the human body to the first drainage tube, the outer walls of the valves 21 are squeezed, causing the side edges of the valves 21 to move toward the inner wall of the tube. The radial gap between the valves 21 increases, and the valves 21 are in an open state. Figure 3 As shown, when backflow occurs, the inner wall of the valve 21 is pushed by the pressure of the drainage fluid to push the side edges of the valve 21 toward the central axis of the drainage tube and stick together. Under the action of the interaction force between the valves 21 and the elastic force of the valve 21 itself, the valves 21 are closed, as shown in FIG. Figure 2 As shown, tissue drainage fluid is flowing backward.

[0036] The above description is only a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
