Description

Technical Field

[0001] The utility model belongs to the technical field of B-ultrasound, and in particular relates to a detachable B-ultrasound probe water bag which replaces a coupling agent. Background Art

[0002] Medical ultrasonic coupling agent is an auxiliary material commonly used in ultrasonic examination and ultrasonic treatment. It can improve the propagation and reception of ultrasonic waves in human tissues, thereby improving the accuracy of medical diagnosis and the effectiveness of treatment. The main function of medical ultrasonic coupling agent is to conduct ultrasonic waves during ultrasonic examination and ultrasonic treatment.

[0003] When ultrasound waves propagate in human tissues, they are absorbed and reflected by the tissues, so a medium is needed to enhance the conduction effect of ultrasound waves. Medical coupling agent is such a medium, which can fill the gap between the ultrasound probe and the human skin, reduce the reflection and refraction of ultrasound waves at the interface of the medium, and enable ultrasound waves to propagate better to the target tissues, thereby improving the clarity and resolution of the image. Another important function of medical ultrasonic coupling agent is to improve the reception effect of ultrasound waves. When ultrasound waves propagate in tissues, they are scattered and attenuated by the tissues, so a medium is needed to enhance the reception effect of ultrasound waves. Medical ultrasonic coupling agent can increase the signal strength of ultrasound waves, reduce the attenuation of signals, and enable ultrasound signals to be better received by the ultrasound probe, thereby improving the brightness and contrast of the image. Medical ultrasonic coupling agent is generally applied directly to the skin surface in gel or liquid form, and the coupling agent on the skin surface needs to be wiped off after the examination. Utility Model Content

[0004] The utility model provides a detachable B-ultrasound probe water bag that replaces coupling agent, aiming to solve the problems that coupling agent needs to be applied on the skin surface during B-ultrasound examination, the coupling agent is easy to contaminate the skin, and it is inconvenient to disinfect during puncture under ultrasound guidance and the coupling agent is easy to contaminate the puncture point.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A detachable B-ultrasound probe water bag that replaces a coupling agent comprises a water bag and a prefabricated fixing part, wherein the prefabricated fixing part is used to fix the water bag to the head end of the B-ultrasound probe; the water bag is egg-shaped and filled with water; a water inlet is arranged on one side of the water bag, and a plug is connected to the water inlet; a plurality of tensioning strips are arranged along the circumferential direction on the outer ring of the water bag, and the tensioning strips are used to connect the prefabricated fixing part.

[0007] Furthermore, the prefabricated fixing part includes two semicircular plates, which are connected in an embrace and close to the outer wall of the upper part of the B-ultrasound probe; a plurality of convex teeth are provided at the upper end of the semicircular plates, and the tensioning strips are connected to the convex teeth to fix the water bag.

[0008] Furthermore, the semi-circular arc plates are plastic parts, and the two semi-circular arc plates are connected by a slot structure.

[0009] Furthermore, the material of the water bag is latex.

[0010] The beneficial effects of the utility model are:

[0011] 1. The latex water bag is soft and ultra-thin, and can fit the B-ultrasound probe very well. During the examination, the water bag can fill the gap between the probe and the human skin under pressure, reducing the reflection and refraction of ultrasound at the medium interface, thereby improving the clarity and resolution of the image;

[0012] 2. The latex water bag is made of surgical latex gloves, which is easy to disinfect. One water bag can be used for one person or one water bag for one examination site. It is disposable, eliminating medical-induced infection during color Doppler ultrasound examination and avoiding cross-infection of related skin diseases.

[0013] 3. The water bag is fixed with prefabricated fixings and tensioning strips, which is convenient for fixing and disassembly and inspection;

[0014] 4. When used for ultrasonic puncture positioning, the latex water bag is used instead of the coupling agent to be applied to the skin of the inspection site. The disinfected area does not need to be coated with coupling agent to avoid the coupling agent from contaminating the skin of the puncture site. BRIEF DESCRIPTION OF THE DRAWINGS
