Solid medical ultrasound coupling patch and preparing method thereof

Abstract

The invention discloses a solid medical ultrasound coupling patch and a preparing method thereof. The solid medical ultrasound coupling patch is prepared from a sodium alginate polymer, carrageenan, xanthan gum, hydroxymethyl cellulose, propylene glycol, glycerol, a preservative and deionized water. The preparing method comprises the steps that the sodium alginate polymer, glycerol, pure water andthe like are taken according to the mass ratio, mixed, heated and stirred evenly, and the mixture is discharged after heat-preservation defoaming is carried out, and then forms products of various specifications and shapes through filling. The solid medical ultrasound coupling patch is convenient to use and has excellent sound conduction and isolation effects; when medical personnel are in contact with infectious patients, the functions of preventing the risk of cross infection in a hospital and protecting the medical personnel are achieved after separation. The solid medical ultrasound coupling patch serves as a coupling medium, is specially applied to black and white ultrasonic equipment, color Doppler ultrasound equipment and the fields of ultrasound focusing and ultrasound treatment,and is suitable for the superficial surface, soft tissue, muscle bones, milk glands and thyroid glands of the human body and other parts where a liquid gel medium is difficult to use in ultrasound application.

Description

technical field [0001] The invention relates to the technical field of biomedicine, and relates to a solid-state medical ultrasonic coupling patch and a preparation method thereof. Background technique [0002] At present, the function of medical ultrasonic coupling agent is to apply the coupling medium between the ultrasonic probe and human skin, to isolate the air between the ultrasonic probe and the skin of the examined part, so that the sound wave conduction is not affected by the air and attenuated, so as to achieve good detection effect. In the ultrasound field market, liquid medical ultrasound coupling agent products are usually used as the gel medium used in ultrasound detection and ultrasound treatment. This kind of medium is a water-soluble product, which is easily melted by the influence of ambient temperature, which brings a lot of trouble to the difficult ultrasonic detection and ultrasonic treatment fields; and for superficial skin tissue, soft tissue, musculo...

AI Technical Summary

Problems solved by technology

This kind of medium is a water-soluble product, which is easily melted by the influence of ambient temperature, which brings a lot of trouble to the difficult ultrasonic detection and ultrasonic treatment fields; and for superficial skin tissue, soft tissue, musculoskeletal, carotid artery, subcutaneous tumor, The use of existing liquid couplant in special positions such as concave and convex parts cannot achieve the desired effect

In addition, when doing long-term ultrasonic detection and ultrasonic treatment, it is necessary to repeatedly replenish the liquid ultrasonic coupling agent, which brings tedious and repetitive work to medical workers, and affects the detection efficiency and detection accuracy.
