Lubricating gel capable of relieving spasm and pain

Abstract

The invention relates to lubricating gel capable of relieving spasm and pain. The gel is prepared from 0.5-0.8% of hydroxypropyl methyl cellulose, 0.8-1.2% of tetracaine hydrochloride, 1.0-2.0% of polyethylene glycol, 0.01-5% of chlorhexidine acetate, 0.01-5% of triamcinolone, 0.01-5% of racanisodamine and the balance purified water. Meanwhile, the gel has multiple effects including that a lubricating function is achieved when cannulas are introduced into human body cavities and endoscopic surgical dry tools enter the human body, local anesthesia is conducted on skin mucosae, and foam of the cavities is removed to relieve the spasm and pain and alleviate mucosa inflammatory edema caused by cannula insertion and other operation. Not only can the examination and surgery time be saved, but also the psychological pain and physical pain of a patient can be alleviated, the success rates of examination and surgery are increased at the same time, damage caused by surgery or instrument operation to the mucosae is reduced, and the lubricating gel has a significant clinical meaning.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an antispasmodic and pain-relieving lubricating gel. Background technique [0002] When the medical device enters the natural cavity of the human body for diagnosis and treatment, due to the nervousness of the patient and individual differences, there will generally be dryness of the cavity, muscle spasm and other reasons, resulting in blockage and poor sliding effect of the medical device, which will bring severe pain to the patient and tension. Therefore, an appropriate amount of lubricant is often applied on the surface of medical devices to reduce the damage of medical devices to human tissues and mucous membranes. [0003] However, the main components of current lubricants are glycerin, mineral oil, paraffin oil, petrolatum, estrogen, and the like. The sensitization rate of these lubricants is as high as 10%, and there is no evaluation of safety, effectiveness, microbial ind...
