preparation Embodiment 2

[0030] Take by weighing 70g chitosan and be dissolved in 6.5L mass concentration and be in the glacial acetic acid solution of 1.00%, turn on ultrasonic wave and make chitosan dissolve completely, add 50gN-hydroxyl succinimide, continue to turn on ultrasonic wave to mix, then add 60g1-( 3-Dimethylaminopropyl)-3-ethylcarbodiimide was stirred until it was completely dissolved, then 38g of arginine was added, and the stirring was continued for 24 hours to obtain a reaction solution, which was subjected to dialysis treatment. Before the dialysis treatment, the dialysis bag was immersed in Sufficiently absorb water in distilled water, then put the reaction solution into a dialysis bag and dialyze with distilled water for 2 days. Pre-freeze for half an hour under the temperature condition of 6° C. to -3° C., and then transfer to a freeze dryer to freeze-dry to obtain arginine-modified chitosan.

Abstract

The invention relates to the technical field of medical detection, particularly to a urine detection test paper for reflecting the human fatigue degree, and a preparation method thereof, wherein the urine detection test paper contains thiol protease, sodium dihydrogen phosphate, water-soluble polythiophene, chloroauric acid tetrahydrate, sodium hydroxide and polyvinyl alcohol, and the surface of the urine detection test paper is coated with a chitosan / titanium dioxide composite film. The preparation method comprises: immersing filtration paper in the mixed solution of a solution A and a solution B, and covering the surface of the filtration paper with a chitosan / titanium dioxide composite film, wherein the solution A contains water-soluble polythiophene, chloroauric acid tetrahydrate, sodium dihydrogen phosphate and sodium hydroxide, and the solution B contains polyvinyl alcohol and thiol protease. According to the present invention, the prepared urine detection test paper has advantages of strong hydrophilicity, convenient operation and high detection sensitivity, and can adsorb and permeate urine protein.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a urine detection test paper that reflects the degree of human fatigue and a preparation method thereof. Background technique [0002] Fatigue is a state of natural exhaustion of one or some organs or even the strength of the whole body due to changes in the physical and psychological state of the laborer during the labor process. Fatigue is a physiological phenomenon as well as a psychological phenomenon. In essence, it is a normal physiological protection mechanism of the body. From a biomedical theory, labor is a process of energy consumption. When this process continues to a certain extent, the central nervous system will have an inhibitory effect. After the fatigue of the central nervous system, it is the fatigue of the motor nervous system, which reflects the sensitivity of the movement. Reduced, work efficiency decreased. Fatigue is a subjective experience of f...
