Description

Technical Field

[0001] The utility model relates to the technical field of digestive tract catheters, in particular to a novel nasointestinal obstruction catheter. Background Art

[0002] Nasal ileus catheter placement is a non-vascular interventional technique that uses a guidewire under endoscopic or X-ray guidance to insert a nasal ileus catheter into the deep small intestine proximal to or beyond the jejunum for complete drainage and decompression. It offers numerous advantages. For simple adhesive ileus, placement of an ileus catheter can effectively relieve the obstruction and avoid surgery. For complex or refractory ileus, an ileus catheter can serve as a small intestinal stent (intestinal lining catheter) to prevent postoperative adhesive ileus. For advanced tumor obstruction, an ileus catheter can be used for preoperative and postoperative gastrointestinal decompression, enteral nutrition, and drug infusion therapy, potentially prolonging patient survival and improving quality of life. Furthermore, small enterography performed with an ileus catheter not only overcomes the diagnostic and positioning difficulties associated with traditional gastrointestinal tract imaging due to intestinal overlap and interference from intestinal contents, but also allows for simultaneous treatment based on the diagnostic findings.

[0003] Existing intestinal obstruction catheters have the following problems during insertion: due to insufficiently smooth surfaces, intestinal obstruction catheters can easily become blocked during insertion, requiring the catheter to be removed and lubricated before continued insertion. This repeated insertion and removal of the catheter increases patient pain and the workload of medical staff. Furthermore, if insufficient lubricant is applied, the catheter may become blocked again later, and repeated removal of the guide rail increases the risk of contamination.

[0004] To this end, the present application designs a novel nasointestinal obstruction catheter to solve the above problems. Utility Model Content

[0005] In order to make up for the deficiencies in the prior art, the utility model provides a novel nasointestinal obstruction catheter.

[0006] A novel nasointestinal obstruction catheter, comprising a main catheter, is characterized by:

[0007] Three channel tubes are inserted into the main conduit, which are a lubricating liquid channel tube, a water injection channel tube and a guide wire channel tube. A water bag is arranged at the end of the main conduit, and the outer layer of the water bag is wrapped with a lubricant release layer.

[0008] Furthermore, in order to better realize the present invention, the water injection channel tube is connected to the water bag, which is used to inject water into the water bag to increase the weight and facilitate forward delivery.

[0009] Furthermore, in order to better implement the present invention, the lubricant release layer is connected to the lubricating liquid channel tube through a connecting tube, and the lubricating liquid injected into the lubricating liquid channel tube is released to the outside in the lubricant release layer.

[0010] Furthermore, in order to better realize the present invention, the lubricant release layer is a double-layer structure, the two layers are connected by a connecting pipe, and a plurality of micropores are opened in the upper layer as release holes for the lubricating liquid.

[0011] Furthermore, in order to better implement the present invention, the lubricant release layer can also be made of a single layer of sustained-release material, and the lubricant release layer is soaked in lubricating liquid in advance and then slowly releases the lubricating liquid in the intestine.

[0012] The beneficial effects of the utility model are:

[0013] The device of the utility model is equipped with a lubricant release layer on the airbag, which can avoid the negative effects of contamination caused by frequent removal of the catheter for smearing lubricant and increased pain for the patient, and can efficiently complete the placement of the intestinal obstruction catheter.

[0018] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0020] Figure 1-Figure 2This is a specific embodiment of the present invention, which is a new type of nasointestinal obstruction catheter. Three channel tubes are inserted into the main catheter 1, namely the lubricating liquid channel tube 2, the water injection channel tube 3 and the guide wire channel tube 4. A water bag 5 is provided at the end of the main catheter 1, and the outer layer of the water bag 5 is wrapped with a lubricant release layer 6.

[0021] The water injection channel 3 connects to the water bladder 5, adding water to increase its weight and facilitate forward delivery. The lubricant release layer 6 connects to the lubricant channel 2 via a connecting tube 601. Lubricant injected into the lubricant channel 2 is released to the outside through the lubricant release layer 6. The lubricant release layer 6 has a two-layer structure, with the connecting tube 601 connecting the two layers. The upper layer has several micropores 602 that serve as lubricant release holes. The lubricant release layer 6 can also be made of a single layer of sustained-release material. After being pre-soaked with lubricant, the lubricant release layer 6 slowly and continuously releases lubricant in the intestine.

[0022] During use of this embodiment, if there is a blockage, lubricating liquid can be injected into the lubricant release layer 6 through the lubricating liquid channel tube 2 without removing the catheter, which reduces the workload of medical staff, alleviates the pain of patients, and avoids the risk of contamination.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
