Disinfection sterilizing type medical supersonic couplant and method of preparing the same

Abstract

The invention discloses a disinfection sterilization medical ultrasonic coupling medium with the bactericidal function and used in the ultrasonic detection and treatment of skin and cavitary mucosa and a preparation method of the coupling medium, wherein, the ultrasonic coupling medium comprises propylene glycol, de-ionized water and one viscosity modifier of the hydroxy ethyl cellulose, carbomer and hydroxy propyl cellulose. The coupling medium further comprises a fungicide of 0.05 to 0.15 percent and the constituents of the fungicide are any one of polyhexamethylene biguanide, benzalkonium chloride, benzalkonium bromide, chlorhexidine acetate, trichlorobenzene phenoxy diphenyl ether and nanometer silver or any combination of the olyhexamethylene biguanide, the benzalkonium chloride, the benzalkonium bromide, the chlorhexidine acetate, the trichlorobenzene phenoxy diphenyl etherand, and the nanometer silver; the preparation method used for preparing the ultrasonic coupling medium is as follows: dispersing the hydroxy ethyl cellulose in the propylene glycol, stirring and dispersing the hydroxy ethyl cellulose by adding enough water, heating to 75 to 80 DEG C, preserving the heat for 30 minutes to cool the hydroxy ethyl cellulose and the propylene glycol to 45 DEG C, adding the fungicide to stir and cool the fungicide, the hydroxy ethyl cellulose and the propylene glycol to obtain the filled coupling medium. Tests show that the products of the coupling medium have fast and long sterilization effect and meet the requirements of various related standards.

Description

technical field [0001] The invention relates to a medical ultrasonic coupling agent, in particular to a sterilizing and sterilizing medical ultrasonic coupling agent with sterilization function used for ultrasonic detection and treatment of skin and cavity mucosa and a preparation method thereof. Background technique [0002] In the prior art, the medical ultrasonic coupling agent is mainly prepared from one of the viscosity modifiers such as hydroxyethyl cellulose, carbomer, hydroxypropyl cellulose, propylene glycol solvent and deionized water. The ultrasonic couplant is often used in clinical ultrasonic diagnosis and treatment, and acts as a coupling between the sound head (ultrasonic probe or treatment head) and the object to be measured, so that the sound waves can smoothly enter the body to obtain reliable images or reach the treated tissue. The basic requirement is that it can transmit sound waves effectively, and the acoustic impedance rate is between the acoustic imp...

Problems solved by technology

In order to avoid cross-infection during ultrasonic detection of the mucous membrane of the cavity, the probe is often coated with an ultrasonic coupling agent and then covered with a condom for detection. In order to facilitate the insertion of the probe into the cavity, an ultrasonic coupling agent is often applied outside the condom Lubrication method is used for detection, which is extremely cumbersome to operate

The general ultrasonic coupling agent not only fails to meet the requirements of sterility, but also because the method of condom covering the probe has a great impact on the sound wave transmission and image clarity, so the development of a rapid and long-term sterilizing medical ultrasonic coupling agent in the cavity Significant in terms of mucosal detection

At present, when it is used for cavity ultrasound treatment, a disposable jacket is added to the probe. The jacket is expensive, with a charge of 30 to 50 yuan each, and a couplant is used, which also has the problem of cavity ultrasound detection.
