Medical sterilization lubricant and preparation method thereof

Abstract

The invention discloses a medical sterilization lubricant, which is prepared from the following raw materials by mass: 1-20% of glycerin, 0.5-10% of carbomer, 5-25% of polyethylene glycol, 0.01-1% ofpreservative, and the balance of purified water. The invention further discloses a preparation method of the medical sterilization lubricant. According to the present invention, by optimizing the components and the contents, the product has the moderate and uniform lubricating property through the synergistic effect of various components, can reduce the damage on tissues and mucous membranes in endoscopy, does not contain gas bubbles, has characteristics of transparent appearance, no influence on microscopic examination vision field clarity, excellent water solubility, easy rinsing, safety, notoxicity and no irritation, and can be cleaned with cold water, wherein the biocompatibility of the product meets the requirements of GB/T 16886.11-2011 and the detection requirements of U.S. NAMSA company.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, relates to a medical lubricant, and also relates to a preparation method of the lubricant. Background technique [0002] At present, in order to diagnose various intraluminal diseases, endoscopy is widely used clinically, and endoscopy has also become the gold standard for the diagnosis of various diseases. Endoscopy includes intestinal endoscopy, gastric endoscopy , Tracheal endoscopy, bladder endoscopy and so on. The endoscope used for disease inspection requires smooth insertion and less stimulation to the lesion, so that the patient can avoid pain and fear as much as possible. For this reason, a layer of medical lubricant must be coated on the endoscope. [0003] Medical lubricants are a type of gel, glue and mineral oil that provide lubricating aids for various instruments during clinical diagnosis and treatment or surgery. They can be divided into oily lubricants and water-based l...

AI Technical Summary

Problems solved by technology

Most of the lubricants used in existing cavity endoscopes have relatively simple components and properties, such as silicone oil, glycerin, liquid paraffin, etc., which only play a lubricating role.

Another example is the Chinese invention patent "A Medical Lubricant" (Application No. 200910194123.2) which discloses a lubricating lubricant composed of glycerin, propylene glycol, xanthan gum, sodium hydroxymethylcellulose, tetracaine hydrochloride, preservatives and water. Although the lubricant contains a variety of ingredients with different effects, it has dual effects of lubrication and local anesthesia, but its more ingredients and mucus in the human cavity are prone to air bubbles or foam, which greatly reduces the clarity of the microscope inspection field, thus have a certain impact on the accuracy of microscopic diagnosis
