Embodiment 1

[0028] A kind of B super coupling agent, its preparation technology comprises the following steps:

[0029] (1), get decyl ammonium chloride and be dissolved in deionized water, make decyl ammonium chloride account for 0.01% by weight of B super coupling agent;

[0030] (2), then add 0.5% allantoin and 1% glycerin that account for the weight percentage of the B-ultrasound coupling agent, and stir evenly;

[0031] (3), finally add sodium carboxymethyl cellulose accounting for 1% by weight of the B-ultrasound coupling agent, and stir until gelling;

[0032] (4), after the configuration is completed, let it stand for 24 hours to obtain the B-ultrasound couplant.

Embodiment 2

[0034] A kind of B super coupling agent, its preparation technology comprises the following steps:

[0035] (1), get decyl methyl ammonium bromide and be dissolved in deionized water, make decyl methyl ammonium bromide account for 5% by weight of B super coupling agent;

[0036] (2), then add allantoin and 0.5% propylene glycol accounting for 0.2% by weight of the B-ultrasound coupling agent, and stir evenly;

[0037] (3), finally add hydroxypropyl methylcellulose ethyl cellulose that accounts for 3% by weight of the B-ultrasound coupling agent, heat and stir until gelatinous;

[0038] (4) Vacuum degassing after the configuration is completed, and the B-ultrasound couplant is obtained.

Embodiment 3

[0040] A kind of B super coupling agent, its preparation technology comprises the following steps:

[0041] (1), get chlorhexidine and be dissolved in deionized water, make chlorhexidine account for 0.1% of the weight percentage of B ultracoupling agent;

[0042] (2), then add allantoin and 3% glycerol accounting for 0.6% by weight of the B-ultrasound coupling agent, and stir evenly;

[0043] (3), finally add carbomer accounting for 1% by weight of the B-ultrasound coupling agent, after fully swelling, add triethanolamine and stir, and adjust the pH value to 6-8;

[0044] (4), after the configuration is completed, let it stand for 24 hours to obtain the B-ultrasound couplant.

Abstract

The invention discloses a B ultrasonic coupler, which comprises the following effective components in percentage by weight: 0.1 to 10 percent of viscosity regulator, 0.1 to 10 percent of skin repairing and moistening humectant and 0.01 to 5 percent of disinfectant. The B ultrasonic coupler has disinfection function, and not only has the advantages of having wave velocity fit with sound velocity of human skin, no irritation and no corrosion on a probe, being easily coated and cleaned, having clear development and the like, but also can perform disinfection to avoid cross infection in the using process; moreover, the coupler is also creatively added with the skin repairing and moistening component, not only greatly reduces the irritation of the components of the coupler, but also is milder and safer for the skin, and is particularly suitable for special groups such as pregnant women, infants and the like.

Description

technical field [0001] The invention relates to an auxiliary product for B-type ultrasound, in particular to a coupling agent for B-ultrasound, and to a preparation method of the coupling agent. Background technique [0002] B-type ultrasound is a testing instrument widely used in clinical practice, and the ultrasonic coupling agent is a very special preparation, which is an auxiliary and extension of the diagnostic instrument in function, and is a medical product similar to external medicines and cosmetics in usage. . Ultrasound couplant is used to apply to the skin of the patient's examination site to isolate it from the air and display a clear image of the examination organ. Therefore, the preparation is required to be non-irritating to the skin, easy to remove, and not to damage instruments. Medical ultrasound couplants (hereinafter referred to as couplants) can be divided into interventional couplants and non-interventional couplants according to different clinical ap...
