Self-heating medical ultrasonic coupling agent device with sterilization and disinfection effects and preparation thereof

Abstract

The invention relates to a self-heating medical ultrasonic coupling agent device with sterilization and disinfection effects and a preparation method thereof. The medical ultrasonic coupling agent device comprises an outer shell. The inside of the outer shell is provided with a coupling agent cavity and a self-heating cavity which are not communicated with each other. The self-heating cavity is filled with a disposable self-heating agent. The coupling agent cavity is filled with a medical ultrasonic coupling agent with sterilization and disinfection effects. The medical ultrasonic coupling agent device utilizes the automatic heating effect of the self-heating agent to perform conduction heating on the medical ultrasonic coupling agent to make the temperature of the medical ultrasonic coupling agent reach about the temperature of the human body surface so that the patient never feels the cold stimulation of the coupling agent when being subjected to the B-ultrasound examination. Moreover, the medical coupling agent has the rapid and efficient sterilization and disinfection effects, guarantees to effectively disinfect an ultrasonic probe and prevent the cross infection in the hospital, has the retention sterilization effect on the skin or the mucosa of the examined region, has simple preparation process and saves investment and cost.

Description

technical field [0001] The invention relates to the field of medicine and hygiene, in particular to a self-heating medical ultrasonic coupling agent device with sterilization and disinfection functions and its preparation. Background technique [0002] Medical ultrasonic coupling agent is a reagent widely used clinically at present. Its function is to strengthen the coupling between the ultrasonic probe and human skin, isolate the air between the ultrasonic probe and the skin of the examined part, and make the sound wave transmission not affected by the air. Attenuation to achieve accurate and clear inspection results. [0003] Traditional medical ultrasonic coupling agent has two major defects: the one, can not sterilize and disinfect the ultrasonic probe and the skin or cavity mucous membrane of the area under examination, which does not meet the requirements of national regulations (promulgated by the Ministry of Health of the People's Republic of China in 2002 No. 27 Ord...

Problems solved by technology

[0003] Traditional medical ultrasonic coupling agent has two major defects: the one, can not sterilize and disinfect the ultrasonic probe and the skin or cavity mucous membrane of the area under examination, which does not meet the requirements of national regulations (promulgated by the Ministry of Health of the People's Republic of China in 2002 No. 27 Order Article 6 of the "Disinfection Management Measures" and Article 12 of Chapter III of the "Nosocomial Infection Management Measures" promulgated by the Ministry of Health of the People's Republic of China No. disinfection level)

However, the traditional medical ultrasonic couplant only plays the role of isolating the air, and has no effect of sterilization and disinfection; the particularity of the material and structure of the ultrasonic probe determines that most disinfectants that have a corrosive effect on plastic, rubber and metal instruments cannot It is used for disinfection of ultrasonic probes; and the soaking method cannot be used to disinfect ultrasonic probes; at the same time, because the operating frequency of B-ultrasound is too high, the disinfection time is required to be as short as possible, usually around 1 minute

Although there are disinfectant medical ultrasonic coupling agents on the market, it is difficult for a single disinfectant formula to kill pathogenic microorganisms in about 1 minute

At the same time, the ultrasonic coupling agent in the prior art only contains a single type of sterilant, which cannot produce a broad-spectrum bactericidal effect

However, there is often antagonism between some commonly used sterilants, and the joint use may weaken their sterilizing effects, making it impossible to achieve the superposition of their antibacterial spectrum, let alone achieve a broad-spectrum bactericidal effect

[0004] The second is that the difference between the gel and the skin temperature on the human body surface is a painful experience for patients undergoing ultrasound examination; Applying ice-cold couplant on the surface often stimulates the patient to shiver; this is even more miserable for some elderly and infirm patients, who often shiver because of the cold, or cannot bear the cold stimulation brought by this gel , while affecting ultrasonography

Now for the traditional medical ultrasonic couplant, although there is an electric heating type couplant warmer, it is not convenient to use, and the machine is relatively expensive
