DETAILED DESCRIPTION

[0024] The following describes the implementation of the present invention in detail with reference to examples, but these examples do not limit the present invention and are merely examples. The advantages of the present invention will become clearer and easier to understand through the examples.

[0025] like Figure 1 and Figure 2 A nasogastric feeding tube with a cleaning function is shown, comprising a catheter body 1 made of medical-grade silicone material with excellent flexibility and biocompatibility, suitable for long-term indwelling in a patient's body. Several flow ports 1.1 are defined on the sidewall of the catheter body 1 near the bottom. A first syringe connector 2 is provided at the open end of the catheter body 1. A cleaning assembly 5 is disposed within the catheter body 1. The cleaning assembly 5 includes a cleaning piston 5.1 and a pull wire 5.2. The cleaning piston 5.1 is disposed at the bottom of the catheter body 1. One end of the pull wire 5.2 is fixedly connected to the cleaning piston 5.1, and the other end of the pull wire 5.2 extends along the length of the catheter body 1 and out of the open end. The pull wire 5.2 can be pulled by an external force to drive the cleaning piston 5.1 along the inner wall of the catheter body 1. The top of the cleaning piston 5.1 has a top surface 5.11 for dislodging obstructions within the catheter body 1, and the bottom of the cleaning piston 5.1 has a circular arc-shaped surface 5.12 that matches the bottom shape of the catheter body 1. The diameter of the traction wire 5.2 is smaller than the diameter of the catheter body 1, and the length of the traction wire 5.2 is greater than the length of the catheter body 1. The traction wire can be made of thin plastic wire.

[0026] The surface of the catheter body 1 is covered with a ceramic coating. This coating is made of a high-purity ceramic material with excellent wear resistance, corrosion resistance, and bioinertness. The ceramic coating is applied uniformly to the catheter body using advanced sol-gel or plasma spraying techniques. The coating thickness is controlled within a certain range to ensure sufficient wear resistance without affecting the flexibility and elasticity of the nasogastric feeding tube. In addition, the surface of the catheter body is covered with a ceramic coating, which can reduce the incidence of tube blockage, because the ceramic structure can reduce the friction between food and the nasogastric tube, reduce the risk of tube blockage and thus reduce the frequency of replacement; improve wear resistance: the ceramic coating has excellent wear resistance, which can significantly extend the service life of the nasogastric tube and reduce the frequency of replacement due to wear; reduce irritation: the ceramic coating has a smooth surface and a small friction coefficient with tissues such as the nasal cavity and esophagus, which can reduce irritation and damage to the patient's mucosa; improve biocompatibility: the ceramic coating has good biological inertness and is not easy to cause rejection reactions in human tissues, thereby improving the safety of nasogastric tube use; easy to clean and disinfect: the ceramic coating surface is smooth and corrosion-resistant, which is easy to clean and disinfect, reducing the risk of cross-infection.

[0027] A second syringe connector 3 is connected to the first syringe connector 2. The first syringe connector 2 is larger than the second syringe connector 3. The first syringe connector 2 has a flow guide cavity 2.1. The lower portion of the second syringe connector 3 matches the dimensions of the flow guide cavity 2.1 of the first syringe connector 2 and fits into and communicates with the flow guide cavity 2.1 of the first syringe connector 2. The first and second syringe connectors 2 and 3 can accommodate syringes of different sizes. The first and second syringe connectors can be connected via a connector.

[0028] The second syringe connector 3 is provided with a sealing ring 4 connected thereto. The second syringe connector and the sealing ring 4 can be connected via a connector. The sealing ring 4 includes a plug 4.1 and a stopper 4.2. The plug 4.1 and the stopper 4.2 are integrally formed. The plug 4.1 can be inserted into the opening at the top of the second syringe connector 3 to seal it.

[0029] like Figures 3 to 5 As shown, the method of using the nasogastric feeding tube with cleaning function of the utility model is as follows:

[0030] When a blockage occurs in the catheter body, the traction wire 5.2 can be pulled to drive the cleaning piston 5.1 to slide along the inner wall of the catheter body 1 to remove the blockage;

[0031] After clearing the obstruction, use the guide wire 6 to push the new cleaning component into the bottom of the catheter body, and finally remove the guide wire 6.

[0032] The above is only a specific implementation method of the present invention. It should be pointed out that any changes or replacements that can be easily thought of by technicians familiar with the field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. The rest not described in detail are prior art.
