Lubricating agent for use in coelom introduction by medicinal appliance

Abstract

The invention relates to a medicinal lubricating agent, in particular to a lubricating agent for use in coelom introduction by a medicinal appliance, which comprises 7 to 20 mass percent of medicinal glycerin, 0 to 5 mass percent of propanediol, 0.2 to 1.6 mass percent of xanthan, 0.4 to 1.8 mass percent of carboxymethyl cellulose sodium, 0.5 to 1.5 mass percent of tetracaine hydrochloride, 0.2 to 1.5 mass percent of antiseptic and the balance of water. The lubricating agent is an aqueous lubricating agent, can narcotize mucosal surface sensory nerve endings, has disinfection and sterilization effect and is an ideal lubricating agent for an endoscope for use in body cavity or tract. The preparation method of the lubricating agent is simple and easy to implement.

Description

Technical field: [0001] The invention relates to a medical lubricant, in particular to a lubricant used for medical equipment and body cavity introduction. Background technique: [0002] During the process of medical devices (diagnostic devices such as endoscopes, colposcopes, cervical forceps, and medical catheters) entering the cavity, it is often necessary to apply an appropriate amount of lubricant on the surface of the medical device to reduce the damage of the device to human tissue. Some gynecological clinics and inpatient departments of most hospitals still use light liquid paraffin oil as a lubricant. Liquid paraffin oil is difficult to clean, has certain irritation to body cavities and other tissues, and is easy to breed mold. There is an urgent need for a high-quality water-soluble lubricant. sex lubricants instead.

[0002] During the process of medical devices (diagnostic devices such as endoscopes, colposcopes, cervical forceps, and medical catheters) entering the cavity, it is often necessary to apply an appropriate amount of lubricant on the surface of the medical device to reduce the damage of the device to human tissue. Some gynecological clinics and inpatient departments of most hospitals still use light liquid paraffin oil as a lubricant. Liquid paraffin oil is difficult to clean, has certain irritation to body cavities and other tissues, and is easy to breed mold. There is an urgent need for a high-quality water-soluble lubricant. Lubricant instead

[0003] At present, there is no good and standard lubricant for the introduction of various instruments and pipelines into the body cavity in clinical practice in my country. In order to diagnose and treat various diseases in clinical practice, the lubricants used in medical treatment in the past were all oily lubricants. Not only do they give people a greasy and uncomfortable feeling, but they are also difficult to wipe and clean. However, the most harmful thing is the corrosive damage of oily lubricants to various medical devices, supplies and appliances made of polymer materials.
