Problems solved by technology

Ultrasound probes used in hospitals are generally not disinfected. After the inspection, only white tissue paper is used to wipe it, and then the next inspection is performed, and medical ultrasound probes are frequently in contact with healthy checkups, patients with infectious diseases, patients with skin diseases, infants, and pregnant women. For different groups of people, the probes often carry a variety of pathogenic microorganisms in clinical examinations, and there is a potential risk of iatrogenic cross-infection, resulting in a serious bacteria-carrying rate of ultrasonic probes.
At present, sterilizing ultrasonic coupling agents have been sold on the market, but these coupling agents have many problems such as poor bactericide effect, unreasonable compatibility between components, easy corrosion of instruments, and damage to the function of the coupling agent itself.

Abstract

The invention belongs to the technical field of medical sterilizing agents and discloses a sterilizing agent used for apparatus in a room for B-scan ultrasonography. The sterilizing agent is prepared by steps of 1) mixing and stirring, 2) stirring and allowing the mixture to stand, 3) fully stirring, 4) heating and stirring, 5) extracting with ethanol, concentrating and crushing and 6) stirring, subpackaging and sealing. The sterilizing agent is stable in performance and simple in preparing process.

Description

technical field [0001] The invention belongs to the technical field of medical disinfectants, and in particular relates to a bactericide used for B-ultrasound chamber instruments and a preparation method thereof. Background technique [0002] B ultrasound is a routine diagnostic method in hospitals. B-ultrasound can clearly display various cross-sectional images of various organs and surrounding organs. Because the images are full of solidity and close to the real structure of anatomy, the application of ultrasound can make an early diagnosis. There are various grades of ultrasonic diagnostic instruments, and the advanced high-end instruments are complex in structure and have the characteristics of high performance, multi-function, high resolution and high definition. Their basic components include five components: emission, scanning, reception, signal processing and display, which are divided into two major components, namely the host and the probe. A host can have one,...
