The medical multifunctional gastrointestinal catheter has a reasonable structural design, which can effectively prevent gastric acid reflux, avoid the user's physical discomfort caused by gastric acid reflux, and even aggravate the user's symptoms, facilitate the patient's later continuous treatment, and is conducive to improving the effect of the equipment in actual use, saving the operator's workflow, reducing the operator's workload, and is conducive to improving the practicality of the equipment in actual use.

[0004] The above device deforms the spring by the pressure of the liquid, and moves the support block downward by squeezing the spring. Even if the spring is small, it still has a certain pressure. It is difficult to deform it only by the pressure of the water flow. In addition, the spring is easily broken when it is corroded by the reflux of gastric acid for a long time, thereby affecting the normal use of the device. Therefore, a medical gastrointestinal catheter is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a medical gastrointestinal catheter, which aims to improve the problem in the prior art that the spring may not be able to move the support block downward.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the utility model, the connecting block and the circular plate are arranged so that the liquid flows downward through the periphery of the circular plate and the water flow holes on the circular block. When the liquid flows back, due to the conical arrangement of the water flow holes, the holes below are smaller, and the plastic material causes the circular block to move upward and contact the circular plate to achieve the purpose of blocking, thereby preventing the liquid from flowing back.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a medical gastrointestinal catheter, including a catheter 1, the catheter 1 is used to connect an infusion bottle, the bottom end of the catheter 1 is provided with a monitoring component 2 for preventing liquid reflux, the bottom end of the monitoring component 2 is provided with a pipeline 3, the bottom end of the pipeline 3 is fixedly connected with a catheter 2 4, the catheter 2 4 is used to be inserted into the patient's stomach, the outer wall of the catheter 2 4 is provided with a fixing component 5 for fixing the device, the monitoring component 2 includes an upper cover 21, the bottom end of the upper cover 21 is fixedly connected with a round sleeve 26, and the bottom end of the round sleeve 26 is fixedly connected with a lower cover 27.

[0030] Reference Figure 2 , Figure 4The inner wall of the circular sleeve 26 is slidably connected with a connecting block 25, and a circular block 24 is fixedly connected to the left side of the connecting block 25. The circular block 24 and the connecting block 25 are both made of plastic and are relatively light, so that the circular block 24 can move upward. A water flow hole 28 is provided in the middle of the circular block 24. The water flow hole 28 is provided with a cone. The cone is provided with a large hole on the upper side and a small hole on the lower side, so that when the liquid refluxes, the circular block 24 can move upward to contact the bottom end of the circular plate 23 to achieve the purpose of sealing and prevent reflux.

[0031] Reference Figure 1 , Figure 2 A connecting rod 22 is fixedly connected to the inner wall of the circular sleeve 26 near the top of the connecting block 25, and a circular plate 23 is fixedly connected to the left side of the connecting rod 22. The liquid flows downward through the four sides of the circular plate 23 and flows downward through the conical holes on the circular block 24.

[0032] Reference Figure 1 , Figure 3 The fixing assembly 5 includes a fixing ring 52, which is fixedly connected to the outer wall of the conduit 24, and a disc 55 is fixedly connected to the bottom end of the fixing ring 52. A rotating block 53 is rotatably connected to the inner wall of the disc 55 near the outer ring of the fixing ring 52. The rotating block 53 and the fixing ring 52 are elastically connected by a torsion spring 51, and the fixing belt 54 is reset by the reverse force of the torsion spring 51. One end of the torsion spring 51 is fixedly connected to the outer wall of the fixing ring 52, and the other end of the torsion spring 51 is fixedly connected to the inner wall of the rotating block 53. A fixing belt 54 is arranged inside the disc 55, and the fixing belt 54 is used to fix the device.

[0033] Working principle: first check whether the various accessories of the device can be used normally, then insert the catheter 24 into the patient's body, and connect the catheter 1 to the infusion device. When the liquid enters the upper cover 21 through the catheter 1, it will enter the round block 24 through the gap around the circular plate 23, and flow to the lower cover 27 through the water hole 28 on the round block 24, and finally enter the patient's stomach through the catheter 24. When the patient's stomach has enough liquid, the liquid will flow back and upward and will contact the round block 24. Since the water hole 28 on the round block 24 is set to be conical and the hole below is smaller, the round block 24 slides on the inner wall of the round sleeve 26 through the connecting block 25. Due to the reflux of the liquid, the round block 24 moves upward. When the round block 24 moves upward and contacts the bottom end of the circular plate 23, it will directly block the bottom end of the circular plate 23, making it sealed to prevent liquid reflux.

[0034] When fixation is required, the fixing belt 54 is pulled outward. When the fixing belt 54 is pulled outward, the fixing belt 54 drives the rotating block 53 to rotate. When the rotating block 53 rotates, the torsion spring 51 is compressed. At this time, the device can be fixed by the fixing belt 54. When the device is finished working, the fixing belt 54 can be untied and loosened, and the fixing belt 54 is reset with the help of the directional force of the torsion spring 51.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
