Abstract

The invention discloses a safe use method for preparing a medical ultrasonic coupling agent sterile product, wherein the method comprises the following steps: S1, putting an unsterilized medical ultrasonic coupling agent material into a stainless steel barrel, and carrying out steam sterilization, wherein the formula of the medical ultrasonic coupling agent material comprises 0.5-1.5% of carbomer,3-5% of propylene glycol, 1-3% of glycerol, 1-2% of triethanolamine, and the balance being purified water; S2, after sterilization, cooling the medical ultrasonic coupling agent material to 25 DEG C-80 DEG C, and packaging, wherein a packaging bag is an aluminum composite film packaging bag, the aluminum composite film packaging bag is of a four-layer film structure, and four layers of films sequentially comprise a polyester layer, an aluminum foil layer, a polyamide or Kevlar layer and a polyethylene or polypropylene layer from outside to inside; and S3, after packaging is completed, carrying out terminal thermal sterilization. For facilitating the use of an operating table, a layer of specially-made paper-plastic bag is sleeved on an aluminum composite film packaging bag of a common sterile product, and then sterilization is carried out again. Compared with other methods, the safe use method is simple to operate, good in product quality and low in production cost.

Description

technical field [0001] The invention relates to the field of sterilization of medical ultrasonic couplants, in particular to a thermal sterilization method for preparing medical ultrasonic couplant sterile products which can be safely used. Background technique [0002] The medical ultrasonic coupling agent is a gel-like preparation used in the human body for ultrasonic examination. Its purpose is to eliminate the air between the ultrasonic probe and the examined part of the human body, strengthen the coupling between the ultrasonic probe and the examined part, and make the sound wave transmission not affected by the air. Attenuation of the influence of the test results to obtain reliable test results and provide a basis for doctors to make a correct diagnosis. At present, the ultrasonic transmission medium used in intracavitary and puncture operations must use medical ultrasonic coupling agent sterile products, which can avoid bacterial infection during diagnosis and operat...
