Coupling agent for ultrasonic bone density detector: analysis of composition, function, price and safety

Ultrasonic bone mineral density detector is a kind of non-invasive and non-radiation medical equipment, which is widely used in the bone mineral density examination of children, pregnant women and the elderly. As an important auxiliary material, coupler plays a vital role in bone mineral density detection. Today, we will introduce the composition, function, price and safety of coupling agent for ultrasonic bone density detector in detail.

First,Composition of coupling agent

The coupling agent is mainly composed of purified water, glycerin, ethanol and other components, which have moisturizing and lubricating effects. In addition, some couplings may also contain disinfection ingredients such as trichlorohydroxy diphenyl ether to ensure the safety of use. These ingredients are water-based polymer gel, pH value is neutral, non-toxic and harmless to human body.

Second, the role of coupling agent

1. Improve image quality: the coupler can fill the tiny pores between the probe and the skin, eliminate the air to block the ultrasonic wave, thus improving the clarity of the image. In ultrasonic detection, the air will block the penetration of ultrasonic waves, resulting in blurred images. The use of couplings can ensure smooth propagation of ultrasonic waves and obtain high-quality images.

2. Reduce the noise resistance: the coupling agent has a sound conductance effect, which can eliminate the air between the skin and the probe, and reduce the impact of the noise resistance on the test results. This helps doctors determine bone density values more accurately.

3. Lubrication: the coupling agent has good lubrication performance, which can reduce the friction between the probe and the skin, so that the probe can slide flexibly. This helps the doctor operate the probe more smoothly during the examination, reducing the discomfort of the patient.

Third, the price of coupling agent

The price of couplings varies according to the brand, specifications and sales channels. In general, the price of medical couplings ranges from a few dollars to dozens of dollars, and the specific price needs to be selected according to actual demand. When purchasing coupler, it is recommended to choose a regular channel to purchase to ensure the quality and safety of the product.

Fourth, the safety of the coupling agent

Coupling agent is a kind of non-toxic and harmless medical product to human body. Its ingredients are water-based polymer gels, pH is neutral, will not cause irritation or allergic reactions to the skin. When using coupler, the patient should ensure that there is no allergic reaction to the coupler and test it under the guidance of a doctor. For special groups, such as pregnant women and patients with implanted pacemakers, testing should be carried out under the guidance of doctors to ensure safety.

In addition, the coupling agent also has the characteristics of easy erasability and no contamination of clothing. At the end of the examination, the doctor will use toilet paper, wet wipes, etc. to wipe the coupling clean, and will not cause any harm to the patient.

The coupler used in ultrasonic bone density detector plays an important role in improving image quality, reducing noise resistance and lubricating effect. Its composition is safe and harmless, moderate price, is an indispensable auxiliary material in ultrasonic bone density detection. When using couplings, patients should follow the advice of their doctor to ensure the safety and accuracy of the test.
