Embodiment 1

[0046] In medical sodium chloride aqueous solution 100mml, add the sodium salt injection of 0.01mg aminodextran sulfate (sodium heparin, Changzhou Qianhong Biochemical Pharmaceutical Co., Ltd., molecular weight is 15 000-19 000 Daltons, in structural formula 1, n=25-32), and 0.15 mg of sodium chloride, to prepare endoscope vision clearing agent 1 (the content of mucopolyglycolipid is about 0.01%, and the content of sodium chloride is about 1.5%).

Embodiment 2

[0048] In medical sodium chloride aqueous solution 100mml, add the sodium salt injection of 0.1mg aminodextran sulfate (sodium heparin, Changzhou Qianhong Biochemical Pharmaceutical Co., Ltd., molecular weight is 12 000-19 000 Daltons, in structural formula 1, n=20-32), deploy endoscope vision clearing agent 2 (mucopolysaccharide lipid content is about 0.1%, sodium chloride content is about 0.9%).

Embodiment 3

[0050] Add 0.1 mg of sodium hyaluronate injection (Alzhi, Japan Biochemical Industry Co., Ltd., molecular weight 5,000-10,000 Daltons, in structural formula 1, n=13-26) to 100 mml of medical sodium chloride aqueous solution, and prepare endoscopic Lens clearer 3 for mirror (about 0.1% mucopolyglycolipid content, about 0.9% sodium chloride content).

Abstract

The invention relates to a visual field clearing agent for an endoscope. The visual field clearing agent is a water solvent containing a high-molecular hydrophilic polymer, and comprises the followingcomponents in percentage by weight: 0.01 to 10 percent of mucopolysaccharide and / or mucopolysaccharide ester represented by a structural formula 1, wherein n = 1 to 80, R1 = H or Na, R2 = H or SO3Na,R3 = COCH3 or SO3Na; 0.9 to 4.5 percent of sodium chloride; and the balance of water.

Description

technical field [0001] The invention belongs to the technical field of medical endoscopes, and in particular relates to a visual field clearing agent for endoscopes. Background technique [0002] Precision treatment equipment is an important guarantee for medical operations. At present, conventional endoscopes cannot meet the requirements of clear, comfortable, durable and immune to environmental changes in endoscopic imaging. The endoscope used is mostly caused by the complex surgical environment of the human body, the heat of the equipment 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, resulting in lens fog. Blurring and ambiguity will have a certain impact on the safety, continuity and efficiency of the operation. In order to overcome the above effects, methods such as coati...
