Abstract

OCR 09WP 06 / 08 / 2568 This invention involves coating urinary catheters using a coating process with an extract from [another ingredient]. Plants in the Myrtaceae family are used to induce the formation of silver nanoparticles both on the surface and within the catheter material. Urine. The coating process involves immersing the urinary catheter in a silver saline solution. The catheter was then immersed in a plant extract from the Myrtaceae family, inducing a reducing process and the formation of... Stable silver nanoparticles are embedded on the catheter surface and in the catheter material.

OCR 09WP 06 / 08 / 2568 1. A process for coating the surface of urinary catheters with silver nanoparticles synthesized using extracts. From plants in the Myrtaceae family, the process is as follows: A. Preparation of silver salt solution: This is done by dissolving a starting material containing silver salt in water. The concentration was 1-10 molar. A silver salt solution was obtained at this stage. B. Next, immerse the urinary catheter in the silver saline solution obtained from step A for 1-120 minutes. For hours, at a temperature of 20-40 degrees Celsius, a urinary catheter is obtained with silver salts on it. The surface and the material within the urinary catheter. C. Dissolve the plant extracts from the Myrtaceae family in the solvent used to prepare the plant extracts from the Myrtaceae family. The concentration was 10-100 mg / ml. At this stage, a solution of plant extracts from the family was obtained. rose apple D. Immerse the urinary catheter obtained from step B in the solution of plant extract from the Myrtaceae family. Step C takes 1-120 hours at a temperature of 20-40 degrees Celsius. In this step, the plant extracts... The Indian gooseberry acts as a reducing agent for silver ions and a preservative in this step. Urinary catheters with silver nanoparticles both on the surface and within the catheter material. J. Use urinary catheters containing silver nanoparticles both on the surface and within the material of the catheter. Step d. Rinse with clean water to remove silver salts and excess, non-reactive extracts. Then, allow it to dry at a temperature of 25-40 degrees Celsius. This step results in a coated urinary catheter. Thanks to the silver nanoparticles. The extracts from plants in the Myrtaceae family can be selected from extracts of the leaves of the Garcinia cambogia tree, eucalyptus leaves, and guava leaves. A guava leaf, a bottle brush leaf, a first-love leaf, a clove leaf—any one of these.

2. A process for coating the surface of urinary catheters with silver nanoparticles synthesized using extracts. From plants of the Myrtaceae family, as per claim 1, where the precursor containing silver salt is selectable from silver nitrate. Which of the following is silver chloride (AgNO3), silver citrate (C6H5Ag3O7), or silver acetate (C2H3AgO2)? One or two types combined.

3. A process for coating the surface of urinary catheters with silver nanoparticles synthesized using extracts. From plants of the Myrtaceae family, under Claim 1, where water can be selected from distilled water, deionized water, or water containing... High purity 4. A process for coating the surface of urinary catheters with silver nanoparticles synthesized using extracts. From plants of the Myrrhaceae family, as per claim 1, where the solvent for preparing extracts from Myrrhaceae plants is selectable. From water, ethanol, methanol.
