Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a decompression device for the gastrointestinal tract. Background Technology

[0002] Currently, gastrointestinal decompression devices utilize the principle of negative pressure suction to remove the contents of the gastrointestinal tract, thereby reducing the pressure within the gastrointestinal tract. This is typically achieved using a drainage tube and a drainage bag, connected by a connector. However, during use, the connection between the connector and the inlet tube often becomes unstable.

[0003] There are many existing technologies for decompression devices for the gastrointestinal tract, such as:

[0004] Chinese Patent Publication No. CN203815937U discloses an improved gastrointestinal decompression device, which includes a drainage tube and a cavity. One end of the drainage tube is connected to a first connector, which has an external thread to prevent it from detaching from the inlet tube. The other end of the drainage tube is connected to a second connector. The inlet tube is located on the top surface of the cavity, and its inner wall has an internal thread that matches the external thread. An outlet tube is located on the bottom outer surface of the cavity, and its surface is flush with the bottom surface. Corresponding plugs are connected to the inlet and outlet tubes. This improved gastrointestinal decompression device prevents the connector from easily detaching from the inlet tube, ensuring negative pressure during drainage and thus thoroughly draining the accumulated fluid from the patient's body.

[0005] Therefore, it can be seen that most pressure reducers and drainage tubes are directly connected by threads. However, during use, unstable connections are inevitable, which reduces the sealing of the connection between the drainage tube and the pressure reducer, making it easy for air or liquid to leak out. This increases the frequency of problems when using the pressure reducer, wastes time, and increases the workload of the user, thereby reducing the practicality of the pressure reducer.

[0006] In view of this, we propose a decompression device for the gastrointestinal tract. Utility Model Content

[0007] The purpose of this invention is to overcome the above-mentioned shortcomings and to provide a gastrointestinal decompression device that reinforces the connection between the drainage tube and the decompression device with a reinforcing component.

[0008] The drainage tube is connected to the pressure reducer via a plug-in assembly, and the connecting plate is clamped by a reinforcement assembly to prevent it from falling off.

[0009] Therefore, this utility model provides a decompression device for the gastrointestinal tract, which includes a decompression device body and a drainage tube. The decompression device body is provided with an inlet and an outlet on its upper side. One end of the drainage tube is provided with a connecting plate. The openings above the inlet and outlet are connected to the lower surface of the connecting plate by a plug-in assembly.

[0010] Both sides of the outer wall of the inlet and outlet are provided with reinforcement components, which are used to increase the sealing of the connection between the drainage tube and the pressure reducing device body.

[0011] As a further improvement to this technical solution, the plug-in assembly includes at least a threaded plug and a slot. Slots are provided above both the liquid inlet and the liquid outlet, and a threaded plug is provided on the lower surface of the connecting plate for plugging into the slot.

[0012] As a further improvement to this technical solution, the reinforcement component includes at least a mounting box. Mounting boxes are provided on both sides of the liquid inlet and the liquid outlet. A stabilizing plate is provided on one side of the upper surface of the mounting box. A top plate is provided on the upper surface of the stabilizing plate. A motor is provided inside the mounting box. The output shaft of the motor passes through the mounting box and is coaxially connected to a lead screw. The other end of the lead screw is rotatably connected to the top plate. A fixing plate is threaded onto the surface of the lead screw.

[0013] As a further improvement to this technical solution, a rubber sealing gasket is provided on the lower surface of the connecting plate.

[0014] As a further improvement to this technical solution, limit shafts are provided on both sides of the lower surface of the top plate. One end of the limit shaft passes through the fixing plate and is fixedly connected to the upper surface of the mounting box. The fixing plate and the limit shaft are slidably connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this gastrointestinal decompression device, the drainage tube is connected to the decompression device via a plug-in assembly, and the connecting plate is clamped by a reinforcement assembly to prevent it from falling off. This not only simplifies operation and improves the sealing of the connection between the drainage tube and the decompression device, preventing air or liquid from leaking out, but also reduces the frequency of problems when using the decompression device, thereby improving its practicality.

[0024] Most pressure reducers and drainage tubes are directly connected by threads. However, during use, unstable connections are inevitable, which reduces the sealing between the drainage tube and the pressure reducer. This can easily cause air or liquid to leak out, increasing the frequency of problems when using the pressure reducer, wasting time, and increasing the user's workload, thereby reducing the practicality of the pressure reducer.

[0025] Please see Figure 1-Figure 3 As shown in the embodiment of this utility model, the device includes a pressure reducing body 10 and a drainage tube 13. The pressure reducing body 10 is provided with an inlet 11 and an outlet 12 on its upper part. One end of the drainage tube 13 is provided with a connecting plate 14. The openings above the inlet 11 and the outlet 12 are connected to the lower surface of the connecting plate 14 by a plug-in assembly 15. Reinforcing assemblies 20 are provided on both sides of the outer wall of the inlet 11 and the outlet 12. The reinforcing assemblies 20 are used to increase the sealing of the connection between the drainage tube 13 and the pressure reducing body 10.

[0026] First, the specific structure of the plug-in assembly 15 is disclosed. The plug-in assembly 15 includes at least a threaded plug 151 and a slot 152. Slots 152 are provided above the liquid inlet 11 and the liquid outlet 12. The lower surface of the connecting plate 14 is provided with a threaded plug 151 for plugging into the slot 152.

[0027] The improvement lies in the fact that by rotating the connecting plate 14, the threaded rod 151 is inserted into the slot 152, thus initially connecting the drainage tube 13 to the pressure reducer body 10. The installation is simple, which not only improves the working efficiency of the pressure reducer, but also improves the flexibility of its use, thereby enhancing the practicality of the pressure reducer.

[0028] Next, the specific structure of the reinforcement component 20 is disclosed. The reinforcement component 20 includes at least a mounting box 21. Mounting boxes 21 are provided on both sides of the liquid inlet 11 and the liquid outlet 12. A stabilizing plate 22 is provided on one side of the upper surface of the mounting box 21. A top plate 23 is provided on the upper surface of the stabilizing plate 22. A motor 24 is provided inside the mounting box 21. The output shaft of the motor 24 passes through the mounting box 21 and is coaxially connected to a lead screw 25. The other end of the lead screw 25 is rotatably connected to the top plate 23. A fixing plate 26 is threadedly connected to the surface of the lead screw 25.

[0029] The improvement lies in the following: When the motor 24 is powered on, its output shaft rotates clockwise, driving the lead screw 25 to rotate and moving the fixing plate 26 upward. At this time, the connecting plate 14 can be installed with the inlet 11 and outlet 12 through the plug-in assembly 15. Then, the output shaft of the motor 24 rotates counterclockwise, bringing the fixing plate 26 closer to the upper surface of the connecting plate 14 and clamping it to prevent it from falling off. This not only simplifies the operation but also improves the sealing of the connection between the drainage tube 13 and the pressure reducer body 10, preventing air or liquid from flowing out and reducing the frequency of problems when using the pressure reducer, thereby improving the practicality of the pressure reducer.

[0030] In order to increase the tightness of the connection between the connecting plate 14 and the liquid inlet 11 and the liquid outlet 12, and to prevent air from flowing and reducing the effect of the pressure reducer, a rubber sealing gasket 16 is provided on the lower surface of the connecting plate 14.

[0031] The improvement lies in the fact that by rotating the connecting plate 14, the threaded rod 151 is threadedly connected to the slot 152. At the same time, the rubber sealing gasket 16 is also deformed and inserted into the inlet 11 or outlet 12, which increases the sealing of the connection between the drain tube 13 and the pressure reducer body 10, preventing air or liquid from flowing out and increasing the inconvenience of using the pressure reducer. This also improves the safety of the pressure reducer and thus improves its practicality.

[0032] Considering that the rotation of the lead screw 25 driven by the motor 24 may change the position of the fixed plate 26 and affect the connection effect between the connecting plate 14 and the liquid inlet 11 and the liquid outlet 12, limit shafts 27 are provided on both sides of the lower surface of the top plate 23. One end of the limit shaft 27 passes through the fixed plate 26 and is fixedly connected to the upper surface of the mounting box 21. The fixed plate 26 and the limit shaft 27 are slidably connected.

[0033] The improvement lies in the fact that when the fixed plate 26 moves up and down by the rotation of the lead screw 25, and the left and right of the fixed plate 26 are restricted by the limiting shaft 27, the fixed plate 26 is prevented from being misaligned, which improves the sealing performance of the connection between the drainage tube 13 and the pressure reducer body 10. This not only simplifies the operation but also improves the safety of the pressure reducer, thereby enhancing its practicality.

[0034] In summary, the working principle of this solution is as follows: First, the motor 24 is powered on and put into operation. The output shaft of the motor 24 rotates clockwise, driving the lead screw 25 to rotate and moving the fixing plate 26 upward. At this time, by rotating the connecting plate 14, the threaded rod 151 is inserted into the slot 152. Then, by rotating the output shaft of the motor 24 counterclockwise, the fixing plate 26 is brought closer to the upper surface of the connecting plate 14 and clamped thereon, thus completing the connection between the drainage tube 13 and the pressure reducing device body 10.
