Abstract

The invention discloses medical lubricant. The medial lubricant comprises the following components in percentage by weight: 0.02%-0.8% of organic silicon antifoaming agent, 0.2%-3% of dyclocaine hydrochloride, 0.1%-25% of glycerol, 0.1%-10% of xanthan gum and the balance of water. The medical lubricant can be used for realizing good lubricity, a good antifoaming effect and good water solubility; and moreover, the medical lubricant has the effects of a quick surface anesthetic effect and the like.

Description

technical field [0001] The invention relates to the field of medical lubricants, in particular to a lubricant used for introducing medical instruments into body cavities. Background technique [0002] Clinically, in order to diagnose various intracavitary diseases, various cavity endoscopes are widely used. When these medical devices (endoscopes, colposcopes, cervical forceps, medical catheters and other diagnostic instruments) enter the human cavity, it is often necessary to Apply an appropriate amount of lubricant to the surface of medical devices to reduce damage to human tissue. The requirements for this kind of lubricant are firstly that it should be able to play a certain anesthetic effect, and has no corrosion to the mirror body, good self-stability, little irritation to the patient, non-toxic and no side effects, and can anesthetize and disinfect the mucous membrane surface of the cavity. , defoaming and other effects. [0003] However, at present, the lubricants u...
