B-ultrasound coupling agent

Every time we go to the hospital for examination and treatment, most doctors will ask us to do an ultrasound. Most people don’t understand the principles behind this and can only see the images displayed on the instrument. How are these images displayed? In fact, it uses an ultrasound coupling agent to assist the instrument, making diagnosis and treatment more accurate and convenient. It is different from other reagents and has no corrosive effect on the instrument. Let's take a look at how the B-ultrasound coupling agent works with the instrument.

1. Existing common disinfectants are highly corrosive to ultrasound probes. Other disinfection methods such as ultraviolet lamps are inconvenient to use due to their large time consumption or complicated operation, and cannot meet the needs. In addition, there are a large number of people examined in the ultrasound department, and the actual situation does not allow for complex and long-term disinfection. Huangshengtang Medical Disinfection Ultrasonic Coupling Agent was developed to address the above difficulties.

2. For hospitals, medical disinfection ultrasonic coupling agents, on the one hand, improve the level of medical services, on the other hand, the sales of in-hospital drugs have exceeded the limit of 40% of the total sales, and hospitals are under tremendous pressure. Medical disinfection ultrasonic coupling agents can reduce the sales proportion of drugs in hospitals.

3. The ordinary coupling agent currently used by the hospital is provided to patients free of charge and is included in the cost expenditure. After using the Huangshengtang medical disinfection ultrasonic coupling agent, the hospital can not only save this part of the expenditure, but also get a 5% sales bonus, which is a two-way benefit of increasing revenue and reducing expenditure.

The main function of the coupling agent is to make the ultrasound probe contact more closely with the skin. Because the frequency of medical ultrasound is 2.5-5M, it cannot be conducted in the air. If there is air between the probe and the skin, the ultrasonic wave will return as soon as it encounters the air and cannot enter the human body, thus failing to achieve the inspection effect.

4. Apply a layer of coupling agent on the skin first to eliminate the air between the probe and the skin. It is a water-soluble polymer colloid with good performance. It can eliminate the air between the probe and the skin to make the image clear. It has no damage to the skin, no irritation, no toxicity, no allergy, and no pollution. Of course, from the perspective of hygiene and comfort, it is best to wash it clean, but there will be no radiation if it is not washed or not washed clean, so please rest assured.

1. Concept of Ultrasonic Couplant

During ultrasound examination, the air between the probe and the patient's skin will prevent ultrasound waves from being transmitted into the human body. In order to obtain high-quality images, a liquid transmission medium is needed to connect the probe and the patient's body surface. This medium is the coupling agent.

2. Reasons for using ultrasonic coupling agent

The purpose of using ultrasonic coupling agent is first to fill the tiny gaps between the contact surfaces to prevent the trace air in these gaps from affecting the penetration of ultrasound; secondly, through the "transition" effect of the coupling agent, the acoustic impedance difference between the probe and the skin is reduced, thereby reducing the reflection loss of ultrasonic energy at this interface. In addition, it also plays a "lubricating" role, reducing the friction between the probe surface and the skin, allowing the probe to slide flexibly for exploration.

3. Impact of Ultrasonic Coupling Agent on Images

The quality of the coupling agent is closely related to the quality of the obtained sonogram. Poor quality coupling agent can cause ultrasonic energy loss, reduced resolution, blurred images, and even irritate the skin and damage the probe.
