Embodiment 1

[0027] 1.0g of polyvinylpyrrolidone (degree of polymerization is 200) was added to 100mml pure water, heated to 40 degrees Celsius to dissolve, then 0.1g of sodium chloride was added, stirred for 30 minutes and then cooled to room temperature, and further stirred for 2 hours (rotating speed 2000 rpm) Then, a clearing agent for endoscope was obtained (content of polyvinylpyrrolidone: 1.0%, content of sodium chloride was about 0.1%). The polymer film prepared by coating the clear agent on the surface of the glass slide not only has the anti-fogging effect, but also the oily droplets drop off on the glass slide in 11.7 seconds.

Embodiment 2

[0029] 1.0g of polyvinylpyrrolidone (degree of polymerization is 200) was added to 100mml pure water, heated to 40 degrees Celsius to dissolve, then 1.0g of sodium chloride was added, stirred for 30 minutes and then cooled to room temperature, and further stirred for 2 hours (rotating speed 2000 rpm) Then, a clearing agent for endoscope was obtained (content of polyvinylpyrrolidone: 1.0%, content of sodium chloride was about 1.0%). Coating the clearing agent on the glass slide surface to prepare the polymer film not only has the anti-fogging effect, but also the oily droplets drop off on the glass slide in 9.5 seconds.

Embodiment 3

[0031] 1.0g of polyvinylpyrrolidone (degree of polymerization is 200) was added to 100mml of pure water, heated to 40 degrees Celsius to dissolve, then added 2.0g of sodium chloride, stirred for 30 minutes, cooled to room temperature, and further stirred for 2 hours (rotating speed 2000 rev / min) Then, a clearing agent for endoscope was obtained (content of polyvinylpyrrolidone: 1.0%, content of sodium chloride was about 2.0%). The polymer film prepared by coating the clearing agent on the surface of the glass slide not only has the anti-fogging effect, but also the oily droplets drop off on the glass slide for 8.6 seconds.

Abstract

A medical endoscopy with a clear field of vision, including polyethylene pyrirol and sodium chloride aqueous solution, which is 5‑50 nanometer, and its weight component content is 0.2‑1.2 %;The content of sodium chloride weight components is 0.1‑5.0 %.The preparation method is to dissolve the polyethylene pyrirol in a 40 -degree aqueous solution, and then add sodium chloride and stir for 30‑150 minutes before cooling to room temperature.Add ethanol and stir for 30‑150 minutes to clear the liquid.The clear liquid process prepared by the present invention is simple. It can be used to prevent fog on the surface of the lens and has a good clear effect.

Description

technical field [0001] The invention belongs to the technical field of medical endoscopes, and particularly relates to a visual field clearing agent for medical endoscopes and a preparation method thereof. Background technique [0002] Endoscopes are widely used in medical diagnostic equipment. At present, conventional medical endoscopes will absorb a large amount of mucus from the patient's body during the use of the endoscope, which can never meet the requirements of clear, lasting imaging quality and freedom from environmental changes. . The specific performance is that the endoscope is fogged and blurred due to the operation environment, the heat of the instruments during operation, the change of the temperature difference between the inside and outside of the mirror tube, the splash pollution of blood and body fluids, and the condensation of water vapor on the surface of the lens into small water droplets. It has a certain impact on the safety, continuity and efficienc...
