Problems solved by technology

At present, most products of medical ultrasonic couplants widely used are sterilized and sterilized to achieve sterility, but medical couplants do not have the effect of disinfection and sterilization on the environment and objects of use.
Due to the frequent contact of the sound head with the detection or treatment parts of different patients, it is easy to cause cross infection, especially for the ultrasonic detection or treatment of the cavity mucosa; in o

Example Embodiment

[0021] Example 1

[0022] The medical disinfection and sterilization ultrasonic coupling agent is preferably prepared from the following raw materials in weight percentage:

[0023]

[0024] The preparation method of medical disinfection and sterilization ultrasonic coupling agent is characterized in that:

[0025] (1) According to the above formula, weigh the carbomer and dissolve it in an appropriate amount of distilled water and swell for 24 hours, as liquid A;

[0026] (2) Dissolve glycerin, ethyl paraben, DPP, chitosan, ethanol, and sodium hydroxide in distilled water in sequence according to the above formula, as liquid B;

[0027] (3) Pour liquid B into liquid A slowly, and stir slowly. Liquid A turns from light milky white to transparent gel. Add distilled water to a sufficient amount, stir evenly, and the pH is 6.

Abstract

The invention belongs to the technical field of a medical ultrasound couplant, and particularly relates to a medical disinfection/sterilization ultrasound couplant and a preparation method thereof. The technical scheme of the invention is as follows: the medical disinfection/sterilization ultrasound couplant is prepared from the following raw materials in percentage by weight: 0.2-0.8% of Carbomer 940, 3-9% of glycerol, 2-10% of ethanol, 0.05-0.4% of ethylparaben, 0.01-0.04% of DPP-300, 0.02-0.06% of chitosan, 0.2-1% of sodium hydroxide and the balance of distilled water. The medical disinfection/sterilization ultrasound couplant provided by the invention has a function of fast sterilization, and the ethylparaben, DPP and chitosan are sterilization bacteriostats. In the invention, the proportion has the functions of saving cost and improving sterilization effect; and the disinfection/sterilization ultrasound couplant causes no stimulus on the skin, further achieves the function of ultrasound disinfection/sterilization and can isolate the air between an ultrasound probe and the skin of a human body, thereby realizing zero decrement in the conduction process of sound waves and acquiring a reliable detection result.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasonic coupling agent, in particular to a medical disinfection and sterilization ultrasonic coupling agent and a preparation method thereof. Background technique [0002] Medical ultrasonic coupling agent is a gel-like preparation used in the human body for ultrasonic examination. Its purpose is to eliminate the air between the ultrasonic probe and the skin of the examined part of the human body, and strengthen the coupling between the ultrasonic probe and human skin, so that the sound wave transmission is not affected. Attenuated by the influence of air to obtain reliable test results and provide a basis for correct diagnosis by doctors. At present, most products of medical ultrasonic couplants widely used are sterilized and sterilized, but medical couplants do not have the effect of disinfection and sterilization on the environment and objects of use. Due to the frequent contact of the soun...
