Embodiment Construction

[0011] The present invention will be further described in detail through specific implementation examples below.

[0012] The manufacture method of urinary catheter provided by the invention comprises the following contents:

[0013] A. acetone and ethanol form a solvent at 1:1, and polylactic acid-glycolic acid copolymer is dissolved in the solvent;

[0014] b. Add nitrofurazone, mix and dissolve, take the supernatant to the container after centrifugation, immerse the catheter in the supernatant in the container, pull it out evenly, and dry it in a drying oven at room temperature until the solvent is completely evaporated. The centrifugal speed is 3000r / min;

[0015] c. Then soak in 3% hydrogen peroxide solution for 15 minutes.

[0016] Hydrogen peroxide has a killing effect on bacterial propagules, viruses, and fungi, and reduces the number of colonies in the catheter. After the sterilized catheter is taken out of the hydrogen peroxide solution, it is advisable to use a ...

Abstract

The invention discloses a manufacturing method of a urinary catheter, belonging to the technical field of medical materials. The manufacturing method comprises the following steps: a, preparing a solvent by adopting acetone and alcohol at the ratio of 1 to 1, and dissolving polyactic-co-glycolic acid in the solvent; b, adding with furacilin, carrying out uniform mixing for dissolving, carrying out centrifugation, taking the supernate, adding the supernate into a container, immersing the urinary catheter into the supernate in the container, uniformly pulling out the urinary catheter, placing the urinary catheter into a drying box, and carrying out drying at room temperature till the solvent volatilizes completely; and c, soaking the urinary catheter in hydrogen peroxide solution with the concentration being 3% for 15 min. With the adoption of the technical scheme, the urinary catheter infection during short-term indwelling is prevented, the cost is low, the manufacturing cost is simple, and the manufacturing time is short.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a method for manufacturing a urinary catheter. Background technique [0002] Urinary catheters are mainly used for urinary catheterization in clinical strokes, fractures, and critically ill patients. They are one of the most commonly used medical devices in hospitals. About 25% of inpatients use urinary catheters during their stay. During use, due to various factors, it is often accompanied by catheter-induced urinary tract infection. Regular cleaning and disinfection of the urethral opening to prevent bacterial invasion is a preventive method that can be taken at present. Once bacteria enter the urethral opening, the protection will fail. Contents of the invention [0003] The purpose of the present invention is to provide a simple, low-cost, effective antibacterial manufacturing method of the catheter to solve the above problems. [0004] For realizing the object ...
