Problems solved by technology

[0004] At present, most of the medical lubricants used in the market have certain safety hazards. Due to the non-standard production process, the viscosity of the product becomes thinner after GAMMA sterilization, and changes from viscose to water, thus losing its lubricating properties. In o

specific Embodiment approach

[0030] A water-soluble medical lubricant consisting of medical glycerin, macrogol-300, macrogol-1450, carbomer, methylparaben, propylparaben, sodium hydroxide and distilled water Prepared, the weight percentage between each component is: Medical Glycerin, 0.8%; Polyethylene Glycol-300, 7.7%; Polyethylene Glycol-1450, 7.7%; Carbomer, 0.8%; Methyl formate, 0.0154%; Propyl paraben, 0.0154%; Sodium hydroxide, 0.24%; Distilled water, 82.7292%.

[0031] Taking 100 kg of prepared liquid as an example, the specific operation is as follows:

[0032] In the first step, weigh 7.7kg of polyethylene glycol-1450 and place it in a stainless steel barrel with a diameter of 40cm, and heat it on an induction cooker for 30-50 minutes until the crystals are completely melted to a liquid state;

[0033] In the second step, weigh 7.7kg of polyethylene glycol-300, mix and stir with the solution of the first step, note that the melted polyethylene glycol-1450 is easy to crystallize at low temperatur...

Abstract

The invention discloses a water-soluble medical lubricant. The lubricant comprises the following components in percentage by weight: 0.3 to 1.5 percent of medical glycerol, 3 to 12 percent of polyethylene glycol-300, 4 to 10 percent of polyethylene glycol-1450, 0.5 to 1.5 percent of carbomer, 0.001 to 0.05 percent of methyl parahydroxybenzoate, 0.001 to 0.05 percent of propyl p-hydroxybenzoate, 0.1 to 0.5 percent of sodium hydroxide, and 74.4 to 92.008 percent of distilled water. The medical lubricant is used for medical diagnosis and treatment instruments such as gastroscopes and enteroscopes entering human bodies, or used when fingers of medical gloves worn by medical personnel enter natural pores of the human bodies.

Description

【Technical field】 [0001] The invention relates to a medical lubricant. 【Background technique】 [0002] Many medical devices will cause mechanical damage to the human body to varying degrees when they penetrate into the human body. Lubricants can minimize damage to body tissues and mucous membranes. [0003] At present, there are four main types of lubricants on the market: water-soluble lubricants, silicone resin lubricants, petroleum lubricants and oil-based lubricants. Among them, transparent water-soluble lubricants are the most ideal and safest medical lubricants. It is non-toxic, sterile, colorless, odorless, non-greasy, and non-irritating. The main component of water-soluble lubricants is water for injection. Its acidity and viscosity are close to those of the human body. It feels more integrated, more hygienic, easy to clean, and non-greasy. , Safer, non-toxic, sterile, non-allergenic. The most notable feature is more natural. Therefore, in the medical clinical tre...
