[0016] Example 1
[0017] A silicone-coated urinary catheter. The urinary catheter is composed of a tube fork 7, a tube body 8 and a spherical membrane 4 in turn. The tube fork 7 is composed of a rubber fork 2 and a funnel 1, and one end of the rubber fork 2 meets the funnel 1. In the connection with the tube body 8, the rubber fork 2, the funnel 1 and the tube body 8 form a Y shape. The other end of the tube body 8 away from the funnel 1 is provided with a drainage hole 5, and the tube body 8 is provided with a balloon part 6, The balloon part 6 is located between the drainage hole 5 and the funnel 1 and close to the drainage hole 5 on the tube body. The balloon 4 is provided with an inflation hole 9, and the balloon 4 is sleeved on the balloon inflation hole 9, and the entire urinary catheter The outer surface of the tube is covered with a silicone coating. A rubber plug 3 is arranged on the rubber fork, and the rubber plug is located at the other end away from the connection be...

[0018] Example 2
[0019] A method for preparing a silicone coated urinary catheter. The preparation steps are as follows: mold cleaning: clean impurities on the mold at room temperature; mold immersion coagulant: immerse the mold in the coagulant, take it out and dry it until no coagulant drips , Dry the mold coated with coagulant at 60°C for 20 minutes; Latex dipping: Dip the dried mold with latex to form the first latex layer on the mold, and the total solid mass concentration of latex in the first latex is 48 %; Shifting and sticking thread: The glue thread is fed into the ball and part of the catheter through the shifting and sticking process, and then dipped and sealed with latex. The total solid mass concentration of latex in the sealing latex is 48%, and the stranded wire is sealed in In the middle of the first layer and the second layer of latex, the dipping time is 50 seconds, and the dipped mold is dried at 55°C for 1 hour, and then the product is taken out of the oven ...
