[0002] Gastrointestinal decompression is a commonly used nursing technique in general surgery. Its purpose is to drain gastric fluid and gas in the gastrointestinal tract, relieve abdominal distension and tension on sutures, and promote wound healing. Using the principle of negative pressure suction, gas and fluid accumulated in the gastrointestinal tract are aspirated to reduce pressure within the GI tract and improve blood circulation in the gastrointestinal wall.

[0003] When using a catheter to suck gas from the intestine to the outside, the catheter needs to be inserted into the intestine. During this process, in order to reduce the friction between the catheter and the intestine, the catheter can smoothly reach the designated position, and avoid the catheter causing scratches to the intestine during this process, a lubricant needs to be applied to the catheter. However, due to the friction between the catheter and the anus, anal canal, rectum and other parts, and the wrinkles on the inner wall of the intestine, as the depth of the catheter entering the intestine continues to increase, the amount of lubricant attached to the catheter will be greatly reduced, resulting in increased friction between the catheter and the intestine, thereby increasing the risk of the catheter damaging the intestine.

[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present application, the specific implementation methods of the present application are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0031] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.

[0032] To simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled.

[0033] See Figures 1 to 6 Understand this application.

[0034] See also Figure 1 , a device for discharging intestinal gas, comprising a working tube 101, a negative pressure device 201 and a syringe 301.

[0035] See also Figures 2 to 5 A suction channel 102 and a drainage channel 104 are provided inside the working tube 101. The suction channel 102 and the drainage channel 104 are arranged along the extension direction of the working tube 101, and the tube wall of the working tube 101 is provided with multiple suction holes 103 and multiple drainage holes 105. The suction channel 102 is connected to the outside world through the multiple suction holes 103, and the drainage channel 104 is connected to the outside world through the multiple drainage holes 105.

[0036] The syringe 301 is a spiral-propelled syringe. The syringe 301 is connected to the drainage channel 104 so that the working liquid in the syringe 301 can enter the outside through the drainage channel 104 and multiple drainage holes 105. The working liquid can be a lubricating liquid, or a liquid mixed with therapeutic drugs and having a lubricating effect. Therefore, when the working tube 101 enters the intestine through the anus, the working liquid continuously enters the outside through the drainage holes 105 and adheres to the outer wall of the working tube 101, reducing the friction between the outer wall of the working tube 101 and the intestine, thereby reducing the possibility of the intestine being damaged by the working tube 101. At the same time, the drug can also be released into the intestine through the drainage holes 105 to treat the patient's intestinal diseases. While extracting intestinal gas in the patient's intestine, the drug can also be released. The drug can quickly reach the affected area, thereby assisting the treatment.

[0037] Those skilled in the art of the present application will understand that there are many ways to implement the syringe 301 in the present application. For example, in one embodiment of the present application, the syringe 301 includes a syringe 304, a threaded rod 302, and a piston 303 disposed in the syringe 304. Figure 6The syringe 304, the threaded rod 302, and the piston 303 are coaxially arranged. The threaded rod 302 is rotatably connected to the piston 303 and is threadedly connected to the syringe 304. When the threaded rod 302 rotates around its own axis, the threaded rod 302 moves relative to the syringe 304 under the action of the thread. The piston 303 is rotatably connected to one end of the threaded rod 302. The threaded rod 302 only rotates relative to the piston 303. When the threaded rod 302 rotates around its own axis, the threaded rod 302 pushes the piston 303 to move along the axis of the syringe 304 in the syringe 304, and the working liquid in the syringe 304 is injected into the intestine. The amount of the working liquid injected into the intestine can be controlled by controlling the rotation speed of the threaded rod 302 to avoid The flow rate of the working liquid entering the intestine is too fast or too slow. At the same time, the working liquid is injected into the intestine by rotating the threaded rod 302. When encountering resistance, the thread can be used to counteract the resistance, so that the working liquid can be injected into the intestine through the drainage hole 105. Of course, there are other ways to realize the spiral propulsion syringe 301, such as the threaded rod 302 and the syringe 304 and the piston 303 are not arranged on the same axis, the threaded rod 302 rotates relative to the syringe 304, and the piston 303 can be driven to move along the syringe 304 under the action of the thread.

[0038] In one embodiment of the present application, the syringe 301 is connected to the drainage channel 104 through the first pipeline 305. The syringe 301 and the first pipeline 305 are detachably connected, thereby facilitating the use of the syringe 301 and facilitating the use of the syringe 301 to extract suitable lubricating fluid or medicine.

[0039] See also Figure 1 、 Figure 2 The negative pressure device 201 is connected to the suction channel 102. When the negative pressure device 201 is working, the negative pressure device 201 sucks the suction channel 102, thereby generating negative pressure at the suction hole 103. The gas and liquid in the intestine can enter the suction channel 102, thereby reducing intestinal gas accumulation in the intestine. The negative pressure device 201 can be a manual pump for manual use or an electrically driven electric pump, as long as it can generate negative pressure at the suction hole 103.

[0040] The suction channel 102 and the drainage channel 104 in the present application can work simultaneously, and perform lubrication operations during the suction process, thereby reducing the possibility of the working tube 101 damaging the intestine.
