Ultrasound couplant constant temperature heating device and its testing method

Abstract

The present invention discloses one kind of constant temperature ultrasonic couplant heating device and its measuring method. The ultrasonic couplant heating device is one double barrel structure, which has an inner barrel of heat conducting material, an outer barrel of heat insulating material, couplant set inside the inner barrel, an electric heating element around the inner barrel, temperature inducing and regulating unit in the middle part of the inner barrel. It heats by means of the heat conduction of the inner barrel and the couplant homogeneously without local overheat. The present invention is superior in that different constant temperatures may be set with functional switch, different duty ratios may be regulated to reach the aim of constant temperature heating, and the electric heating element may be set in the inner wall of the inner barrel.

Description

Technical field: [0001] The invention is an ultrasonic couplant constant temperature heating device and a test method of the couplant. Background technique: [0002] With the improvement of people’s awareness of health care, B-ultrasound examination has become an indispensable method in modern medical diagnosis and routine examination and diagnosis. Ultrasound couplant has also become a necessary medical material. Ultrasound couplant is used in transmitting heads and be There is a coupling effect between the measuring objects, so that the sound waves can enter the body smoothly to obtain a reliable image. The basic requirement is that it can effectively transmit sound waves, its acoustic impedance is close to that of human tissues, the sound wave attenuation is small, and clear images can be obtained, and it has no damage to the ultrasound probe, easy to spread, non-toxic to the human body, and non-toxic to the skin. Irritating and easy to scrub. Most hospital couplants are store...

AI Technical Summary

Problems solved by technology

The above patents have the following disadvantages respectively: (1) the amount of heating couplant is small, and only 1-2 bottles of couplant can be heated at a time, which is not suitable for use in large and medium-sized hospitals; (2) the heat source is heated at the bottom of the bottled couplant, which takes a long time , the bottom of the couplant is hot, the surface is cool, and the heating is uneven; (3) The induction temperature adjustment device is placed 2cm away from the bottom of the couplant bottle. Complete; (4) All patents do not test the influence of temperature on the chemical properties of the couplant and whether the heated couplant affects the quality of the ultrasonic image, which is not scientific enough; (5) The price of the existing heating device is relatively high

At present, there is no report of a similar heating device in foreign countries
