example 1

[0019]Mix lecithin and stigmasterol in a beaker at a mass ratio of 3:1, and add mixed enzyme with 0.4 times the mass of lecithin and absolute ethanol with 0.4 times the mass of lecithin to the beaker at a temperature of 45°C and a rotation speed of 320r After stirring and mixing for 30 min under the condition of the pretreatment mixture, the pretreatment mixture was obtained; the phosphate buffer solution with 0.3 times the mass of the pretreatment mixture was heated to 50°C, and then added to the pretreatment mixture at a rate of 0.2mL / s. After stirring and mixing for 160 minutes at a temperature of 50°C and a rotational speed of 300r / min, the mixed enzyme liposome blank was obtained. The mixed enzyme liposome blank was placed in an ice-water bath and ultrasonically oscillated under the condition of an ultrasonic power of 120W. After 15 minutes, filter the mixed enzyme liposome blank after ultrasonic oscillation with a filter membrane with a pore size of 0.48 μm to obtain a fi...

Abstract

The invention discloses a preparation method of a biological membrane cleaning agent and belongs to the technical field of a medical material. The preparation method comprises the following steps: sequentially weighing 20 to 30 parts by weight of mixed enzyme liposome mixture, 15 to 22 parts by weight of a liposome additive, 10 to 15 parts by weight of microcapsule, 4 to 8 parts by weight of surfactant and 50 to 60 parts by weight of water, mixing the mixed enzyme liposome mixture and the liposome additive into a stirring machine, adding the microcapsules and the water into the stirring machine, stirring and mixing for 15 to 30 minutes under the conditions that the temperature is 25 to 35 DEG C and the rotating speed is 200 to 300 r / min to obtain a cleaning agent blank, mixing the cleaningagent blank and the surfactant into a material mixing machine, and stirring and mixing for 15 to 20 minutes under the conditions that the temperature is 18 to 25 DEG C and the rotating speed is 200 to 220 r / min to obtain the biological membrane cleaning agent. The biological membrane cleaning agent obtained by the method has excellent cleaning effect.

Description

technical field [0001] The invention discloses a preparation method of a biofilm cleaning agent, which belongs to the technical field of medical materials. Background technique [0002] Minimally invasive surgery is the focus and development direction of this century. With the extensive development of clinical minimally invasive surgery, there are more and more types of endoscopic surgery. How to ensure the quality of cleaning and sterilization of endoscopic instruments has become a An important subject of sterilization work research. Medical device cleaning is to reduce the organic matter, inorganic matter and microorganisms on the device to a safer level through physical and chemical methods. Laparoscopic instruments have the characteristics of high precision, precious, special materials, multiple lines, multiple grooves, and multiple lumens. They cannot be subjected to high-temperature treatment, and it is extremely difficult to clean, disinfect, and sterilize after use....
