Embodiment 1

[0034] A kind of manufacturing method steps of novel double J tube:

[0035] 1. First use polyurethane to make catheters with the same inner and outer diameters with hardnesses of 50A and 70A respectively. Both catheters have an outer diameter of 4F, an inner diameter of 0.8mm, and a length of 100cm;

[0036] 2. Cut catheters with different hardness into catheters of a certain length according to needs, which can be 5cm, 10cm, 15cm, 20cm, 25cm, 30cm. Note that the cutting end should be flat and free of burrs, otherwise it will affect the surface of the catheter during welding. smooth;

[0037] 3. Select 50A catheter 15cm and 70A catheter 30cm, select the appropriate size of the metal core to insert into the catheter with different hardness. Choose a 5cm metal outer sleeve to be inserted into catheters of different hardness with metal inner cores. The metal inner core and metal sleeve are made of special materials and processes, such as plasma polishing technology, and it mus...

Embodiment 2

[0041] 1. First use polyurethane to make catheters with the same inner and outer diameters with hardnesses of 65A and 75A respectively. Both catheters have an outer diameter of 5F, an inner diameter of 0.92mm, and a length of 100cm;

[0042] 2. Cut catheters with different hardness into catheters of a certain length according to needs, which can be 5cm, 10cm, 15cm, 20cm, 25cm, 30cm. Note that the cutting end should be flat and free of burrs, otherwise it will affect the surface of the catheter during welding. smooth;

[0043] 3. Select a 15cm2 section of the 65A catheter and a 15cm section of the 75A catheter, and select a 50cm metal core to insert into the catheter with different hardness. Select the appropriate metal outer sleeve to fit into catheters of different hardness with metal inner cores. The outer diameter and inner diameter of the metal inner core and the metal casing should be smooth without any burrs and unevenness.

[0044] 4. Put the two sections of catheters...

Embodiment 3

[0047] 1. First use polyurethane to make catheters with the same inner and outer diameters with hardnesses of 65A and 90A respectively. Both catheters have an outer diameter of 6F, an inner diameter of 1.3mm, and a length of 100cm;

[0048] 2. Cut catheters with different hardness into catheters of a certain length according to needs, which can be 5cm, 10cm, 15cm, 20cm, 25cm, 30cm. Note that the cutting end should be flat and free of burrs, otherwise it will affect the surface of the catheter during welding. smooth;

[0049] 3. Choose 65A catheter 15cm and 90A catheter 20cm, choose the appropriate size of the metal core to insert into the catheter with different hardness. Choose a 5cm metal outer sleeve to be inserted into catheters of different hardness with metal inner cores. The metal inner core and metal sleeve are made of special materials and processes, such as plasma polishing technology, and it must be ensured that the outer wall or the inner and outer walls are smoot...

Abstract

The invention discloses a double-J tube and a preparation method thereof and belongs to a new product obtained through technology improvement and stage change on the basis of a traditional double-J tube. The double-J tube is composed of a pelvis end elastic ring, a bladder end elastic ring and a drainage pipe. The whole double-J tube is formed by connecting catheter ends of materials with different hardnesses. Catheters with different hardnesses are welded and made into novel double-J tubes with different hardnesses, the comfort degree of a patient can be effectively improved after the double-J tube is placed in the body of the patient, pain is relieved, complications are reduced, the life quality of the patient is improved, and the treatment effect is improved.

Description

technical field [0001] The invention relates to a medical device used for support and drainage of the upper urinary tract, specifically a double J tube and a preparation method thereof, which belongs to a new product based on the technical improvement and state change of the traditional double J tube. Background technique [0002] At present, the traditional double J tube is widely used in the urology departments of major hospitals across the country to routinely indwell the ureteral drainage catheter after surgical treatment such as ureteral stricture, malformation, calculi, renal pelvis repair, and renal calculus treatment. According to statistics, more than 500,000 traditional double-J tubes are used every year in the country. Due to the difference in physique and tolerance of patients, there are often discomforts in the bladder due to the traditional double-J tube indwelling in the patient's ureter, Symptoms such as pain and even bleeding affect the quality of life of pa...
