Ultrasonic therapy couplant, its preparing process and packing apparatus

Abstract

The invention belongs to ultrasonic therapy technology field, specifically relates to ultrasonic therapy coupling agent and its preparation methods and packaging equipment. Ultrasonic coupling agent contains weight percentage components as follows: Carbomer 0.5 ~ 10%, solvents 74 ~ 98.7%, metronidazole 0.1 to 2%, moisturizer 0.5 ~ 10%, antibiotic drugs 0.1 ~ 2 %, narcotic drugs 0.1 ~ 2%. The preparation method of ultrasonic coupling agent includes the steps: (1) weighing component according weight percentage; (2) mixing the components uniformly or dissolving them; (3) adjusting the pH to 5.5~8.0; (4) stirring fully and uniformly; (5) degassing canning and disinfecting. The packaging equipment of ultrasonic coupling agent, the device consists of container and catheters for containing ultrasonic coupling agent. The front end of catheter is to blunt round shape, the container is spring bottle-type or syringe-type. The invention can control the viscosity of the coupling agent with advantages of security, stability and good acoustic performance. The ultrasonic therapy using the coupling agent can effectively prevent skin burns and ultrasonic therapy smoother movement or slide caused bycoupling agent self, treatment surface is clean, and it has anti-infective role after treatment.

Description

Ultrasound therapy coupling agent, preparation method and packaging device thereof Technical field The invention belongs to the technical field of ultrasound therapy, and specifically relates to an ultrasound therapy coupling agent, a preparation method thereof, and a packaging device. Background technique In the field of ultrasound treatment technology, a coupling agent is a substance that is coupled between the ultrasound head and the skin to fill the gap and prevent the air layer from causing interface reflections to facilitate the passage of ultrasound energy (Feng Ruo, edited by Wang Zhibiao. Practical ultrasound Therapeutics. First edition, Beijing, Science and Technology Literature Press. 2002; 11:206). In current ultrasound therapy, common coupling agents (such as castor oil, liquid paraffin, glycerin and petrolatum) and distilled water are commonly used in ultrasound therapy. Ordinary coupling agents basically use large-volume packaging and cannot be aseptic in a sin...

Problems solved by technology

When distilled water is used as the ultrasonic coupling agent, it is generally used in two situations. One is to immerse the treatment surface and the treatment head in distilled water. This coupling method has a good effect, but it is not easy to implement in general treatment The second is to use distilled water to maintain coupling between the ultrasonic treatment head and the treatment surface, but because the treatment surface is often not horizontal, such as the treatment of some gynecological diseases, such as leukoplakia, chronic cervicitis, etc., due to the special Distilled water can only be sprayed directly on the target area, but the distilled water has poor viscosity and is easy to flow around. It needs a lot of water to fill and cannot couple the ultrasonic head and the treatment surface well, thus polluting the operating environment. And bring a lot of inconvenience to doctors and patients, at the same time, there is no analgesic effect
