A one-step process for coating urinary catheters with silver nanoparticles.

Abstract

OCR 10KL (09 / 04 / 2568) A one-step process for coating urinary catheters with silver nanoparticles, as invented. This procedure involves preparing a silver saline solution and coating the urinary catheter. In the preparation... A silver salt solution is prepared by using a silver salt starter and deionized water as a solvent. This will yield a silver salt solution with a concentration of 0.01-0.1 g / ml, which is then used to coat the catheter tubing. Urination is performed by inserting a urinary catheter made of natural rubber, which is flexible and porous. Immerse it in a silver salt solution and stir under a magnet at a temperature of 25-30 degrees Celsius for 4-24 minutes. After an hour, carefully rinse with deionized water to remove any non-reactive silver salts. Allow to dry at a temperature of 25-30 degrees Celsius, resulting in a urinary catheter coated with silver particles. No

Claims

OCR 10KL (09 / 04 / 2568) 1. The one-step process for coating urinary catheters with silver nanoparticles is as follows: A. Preparation of silver salt solutions by using any type of silver salt as a starting material. One or two types, or more, use deionized water as a solvent. Procedure. This will yield a silver salt solution with a concentration of 0.01-0.1 g / ml. B. Catheter coating. This involves applying a coating to the urinary catheter, which may be a catheter itself. A urinary catheter connected to the urethra, or a urinary catheter connected through the abdominal opening (cystoscopy). A catheter (catheter) containing natural rubber, which is flexible and porous, is immersed in... Prepare a silver salt solution with a concentration of 0.01-0.1 g / ml from step A and stir. Under a magnet at a temperature of 25-30 degrees Celsius for 4-24 hours, then rinse with water. Deionize and dry at 25-30 degrees Celsius. This step results in a catheter tube. Urine coated with silver nanoparticles.
