Problems solved by technology

These commonly used high-efficiency disinfectants also have the following defects: 1. Disinfectants can interact with pathogens, and after contacting with the skin, the residues are harmful to the human body, especially in contact with the cavity, mucous membranes, etc., which are highly irritating and corrosive , and even easily cause allergies, teratogenicity, carcinogenicity and other phenomena
For example, methyl and propyl benzoate antibacterial preservatives are known to be effective against mold and yeast, but frequent use can cause skin and mucous membrane allergic reactions, and hydroxybenzaldehyde has been considered by the World Health Organization as an unidentifiable carcinogen
2. The chemical properties of the disinfectant are active, and when in contact with the probe, it has a strong corrosive effect, which affects the service life of the probe; 3. The common disinfectant is compatible with the coupling agent, which has an antagonistic effect and is easy to form white suspended particles, which affects the ultrasonic performance. Technical indicators, while the patient's comfort is reduced after use
Does not meet the requirements for ultrasound

Abstract

The invention discloses an antibacterial medical ultrasonic coupling agent, which is composed of bioactive bacteriostatic components ε‐polylysine and natamycin, small molecule collagen, triethanolamine, glycerol, carbomer 940, Prepared from purified water, etc. In addition, the preparation method of the coupling agent is also disclosed. The coupling agent of the present invention has instant disinfection, non-toxic, non-irritating, non-sensitizing, and high safety; at the same time, it can moisturize the skin and promote the repair of damaged skin; the product has simple compatibility, stable performance, and good biocompatibility. The cost is low and the preparation process is simple.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasonic coupling agent, and in particular relates to an antibacterial medical ultrasonic coupling agent and a preparation method thereof. Background technique [0002] Medical couplant is a necessary medium in the process of ultrasonic diagnosis and treatment. It is used to eliminate the air film between the skin and the probe, which can effectively prevent air from entering, so that the ultrasonic wave can smoothly enter the body under test, thereby obtaining a clearer image. Ultrasound probes are highly sensitive medical instruments, which are easily damaged by improper operation or contact with some incompatible chemical disinfectants. After use in most hospitals in China, they are simply wiped and not thoroughly disinfected. Ultrasonic probes are frequently used in clinical work, directly in contact with the patient's skin and cavity, and carry many types of bacteria. According to relevant...
