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...
