Medical ultrasonic disinfection coupling agent and preparation method thereof

Abstract

The invention discloses a medical ultrasonic disinfection coupling agent. The medical ultrasonic disinfection coupling agent comprises the following components in percentage by weight: 0.03 to 0.1% ofchlorhexidine gluconate, 0.002 to 0.01% of terpilenol, 0.1 to 0.5% of chitosan, 10 to 20% of a wetting agent, 0.8 to 1.6% of distearyl alcohol polyether, and 0.08 to 0.15% of a preservative, with thebalance being purified water. The invention also discloses a preparation method of the medical ultrasonic disinfection coupling agent. The medical ultrasonic disinfection coupling agent is colorless,non-toxic and non-irritant, has proper viscosity, good conductivity, low ultrasonic energy loss, high resolution ratio, clear ultrasonic development, high safety, and efficient, rapid and lasting disinfection and skin-moistening effects, can disinfect an ultrasonic probe at any time while realizing sterilizing, and avoids cross infection in clinical examination. In addition, the medical ultrasonic disinfection coupling agent is wide in raw material source, simple in preparation process, low in cost and easy to popularize and apply in the market.

Description

technical field [0001] The invention belongs to the technical field of medical disinfection, and in particular relates to a medical ultrasonic disinfection coupling agent. In addition, the invention also relates to a preparation method of the medical ultrasonic disinfection coupling agent. Background technique [0002] Medical ultrasonic couplant is one of the most frequently used consumables in clinical practice. Its characteristics should be harmless to the human body, non-irritating to the skin, non-allergic, easy to erase, good thixotropy and non-dripping, easy to operate, not easy to dry, Not easy to rancidity, clear ultrasonic imaging, suitable viscosity, non-greasy, easy to slide the probe, and at the same time can moisten the skin, eliminate air on the skin surface, good lubrication performance, easy to spread; the most important thing is that during ultrasonic examination, The ultrasonic coupling agent fills the tiny gaps between the probe and the contact surface, s...

Problems solved by technology

[0003] In the process of ultrasound diagnosis and treatment, the external ultrasound probe and coupling agent directly contact the patient's skin, mucous membrane of the cavity, and even contact the patient's open wound, ulcer, catheter and some equipment for maintaining vital signs, which is easy to cause cross-infection; currently, the market There are many kinds of medical ultrasonic disinfection coupling agent, such as Chinese patent CN105983107A provides a new type of medical disinfection and sterilization ultrasonic coupling agent, with magnolol as the main bactericidal component, syringic acid, anisic acid, dipotassium glycyrrhizinate and pandan Some researchers have shown that these plant extracts can only achieve antibacterial and antibacterial effects, but not rapid sterilization; for example, Chinese patent CN104189927A achieves bactericidal effect by compounding six kinds of Chinese herbal essential oils, and the mixed smell of various Chinese herbal essential oils is mixed. Closed B-ultrasound chamber is inconvenient to use frequently, and the preparation process is complicated; another example is to use chemical composition as bactericide: Chinese patent CN101249268A uses (0.05%-0.15%) polyhexamethylene biguanide, benzalkonium chloride, benzalkonium bromide , chlorhexidine acetate, trichlorophenoxydiphenyl ether, nano-silver or a combination of them as bactericidal ingredients; Chinese patent CN101219223A uses (0.2%-2%) 2,4,4-trichloro-2-hydroxy Phenyl ether is a bactericidal component and cannot be biodegraded, and the amount of chemical bactericide added is large, and it will remain on the skin after ultrasonic diagnosis, which has a certain stimulating effect on the skin
