Background

B-mode ultrasound is an imaging discipline that utilizes the physical properties of ultrasound waves for diagnosis and treatment, called ultrasound medicine. The clinical application range of the method is wide, and the method is an indispensable diagnostic method in modern clinical medicine at present. When B-ultrasonic examination is carried out, a layer of contrast medium, which is a water-soluble high-molecular colloid, must be coated between the probe and the skin for B-ultrasonic examination, and is used for removing air between the probe and the object to be examined, so that ultrasonic waves can effectively penetrate into the object to be examined to achieve the purpose of effective examination.

However, the existing applicators are recycled, so that if the former user has skin infection, the former user can be infected with the next user with great certainty, which causes safety hazards and is uncomfortable to use due to the relatively cold condition when the contrast medium is applied in winter. For this purpose, we propose a disposable applicator for B-ultrasonic contrast agent for medical use.
