When we operate the ultrasonic bone mineral density detector, we will apply coupling agent to the test site first, but do you understand why the ultrasonic bone mineral density detector should apply coupling agent? As an ultrasonic bone mineral density detector manufacturer, today we will come to understand with you what effects the application of coupling agent has on the ultrasonic bone mineral density detector.
The main role of coupler
The main function of the coupler is to remove the air between the probe and the skin, so that the ultrasound can be smoothly detected. Ultrasonic waves decay very quickly in the air, and if there is air between the probe and the skin, the ultrasonic waves will be difficult to penetrate, thus affecting the reliability of the test results. The coupler can effectively fill these tiny gaps to form a good conducting medium. The coupling agent also has a certain lubricating effect. During ultrasound bone mineral density testing, the probe needs to slide on the skin of the subject, and if there is no lubrication of the coupling agent, the friction between the probe and the skin will become greater, which will not only make the detection process difficult, but also may cause discomfort to the subject. The presence of a coupler reduces this friction, making the inspection process smoother and increasing the comfort of the subject.
Composition of coupler
The main components of the coupler include purified water, glycerin, ethanol, etc., which have a moisturizing effect and can prevent dry skin from dandruff. During ultrasonic testing, if the skin is dry, the conduction effect of the ultrasonic wave may be affected, and the moisturizing effect of the coupling agent can ensure that the skin is moist, thereby improving the reliability of the test results.
Precautions for use
When using an ultrasonic bone density detector for detection, there are a few things to pay attention to. For example, the client should avoid applying cosmetics, nail polish, etc. on the test site, so as not to affect the ultrasound imaging. At the same time, for some special groups, such as pregnant women should be tested under the guidance of a doctor to ensure safety.
Applying coupling agent to ultrasonic bone density detector can reduce the detection error to a certain extent and make the detection results more reliable.
