Problems solved by technology

Since the doctor cannot evenly apply the couplant during the actual operation, the amount of hand force during the operation also affects the thickness of the couplant
As a result, the acoustic impedance is unstable and it is difficult to obtain high-quality ultrasound images
And for the doctor, the couplant needs to be applied on the patient's skin, which increases the diagnosis time and increases the doctor's work intensity. It is also an annoying thing for the patient. After the ultrasound examination, a lot of paper towels are needed to wipe the skin The residual couplant on the surface causes a lot of resource waste and forest destruction, and dirty clothes

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0032] Hydrogel coupling pads for medical ultrasonic diagnostic instruments are mainly made of carbomer 940GE, glycerin, triethanolamine, sodium lauryl sulfate, ethyl acrylate, and water.

[0033] Such as figure 1 As shown, the preparation method of the special hydrogel coupling pad for medical ultrasonic diagnostic instrument comprises the following steps:

[0034] 1. First, sprinkle Carbomer 940GE 6g on the surface of about 500mL of water in the material tank A, and let it stand for more than 24 hours to fully swell to obtain A liquid;

[0035] 2. Then take 5ml of triethanolamine, 50ml of glycerin, 5ml of sodium lauryl sulfate, 5ml of Tween-80, 1.0g of ethyl acrylate, add about 400mL of water in the material tank B, heat to dissolve, let cool, and obtain B liquid;

[0036] 3...

Abstract

The invention relates to the technical field of a coupling product for a supersonic wave diagnostic device, particularly to a hydrogel coupling pad special for a medical supersonic wave diagnostic device. The coupling pad is mainly made from carbomer 940 GE, glycerin, triethanolamine, sodium dodecyl sulfate, ethyl acrylate and water. The preparation method of the hydrogel coupling pad comprises the following steps: (1) adjusting a special hydrogel original liquid, (2) solidifying the hydrogel original liquid, (3) radiating a freezed hydrogel pad blank, (4) cleaning and purifying the radiated hydrogel pad, and (5) checking and packaging the obtained pad to obtain a final product. The technical scheme provided in the invention has the beneficial effect that the definition of medical ultrasound imaging is greatly improved, and the hydrogel coupling pad is in a hydrogel solid state, has no viscosity, and leaves no residue on the surface of people's skin, so that the pad doesn't require wiping with a tissue and is eco-friendly and clean.

Description

technical field [0001] The invention relates to the technical field of coupling products for ultrasonic diagnostic instruments, in particular to a special hydrogel coupling pad for medical ultrasonic diagnostic instruments. Background technique [0002] Start by understanding why ultrasonography uses couplants. According to physics, when an ultrasonic wave hits the interface between two different media, reflection will occur, which will reduce the acoustic energy of the ultrasonic wave entering another medium. The degree to which ultrasonic waves are reflected is related to the acoustic impedance indicators of the two media, and the acoustic impedance indicates the ability of a certain medium to hinder the propagation of ultrasonic waves. Of course, different media will have different acoustic impedances. From a physical point of view, the greater the difference between the acoustic impedances of the two media, the more reflections will occur. Therefore, in ultrasonic exam...
