Cholinesterase visual observation color matching card and manufacture method thereof

Abstract

The invention discloses a choline esterase visual colorimeter and a preparation method for the same, comprising a test paper wool and a standard colorimeter, wherein, the standard colorimeter comprises six color blocks; the color of each color block is the same with the color of blood with corresponding choline esterase activity; each color block represents corresponding choline esterase activity which is relatively 0 percent, 30 percent, 50 percent, 70 percent, 80 percent and 100 percent from light to heavy; an interpretation hole is arranged on the center of each color block; the size of the interpretation hole is equal to the area of a round which is formed by tiling of a drop of blood; the reverse sides of the color blocks of the standard colorimeter are provided with pressed films. The invention also comprises a transparent thin plastic sealing sack with an area which is slightly larger than that of the test paper wool. The preparation method and the use method of the invention are very simple and convenient; because a reagent strip is directly compared with the standard colorimeter and no transparent thin plate is isolated between, the detection result is more accurate; the choline esterase visual colorimeter can be used under a common daylight lamp, does not need a power source and batteries, has smaller volume, is convenient in carrying, and greatly reduces the cost.

Description

technical field [0001] The invention relates to a device capable of testing the activity of cholinesterase in human blood, in particular a measuring device capable of judging the activity of cholinesterase after organophosphorus poisoning. Background technique [0002] Organophosphorus pesticides can be easily absorbed into organisms through the respiratory tract, digestive tract, skin or mucous membranes through different states (gas state, vapor state, aerosol state, liquid state) and cause poisoning quickly. The mechanism of organophosphorus pesticide poisoning is mainly that pesticides selectively inhibit the activity of cholinesterase in the nervous system, causing a large accumulation of acetylcholine, the transmission medium of cholinergic nerves, and acting on cholinergic receptors, resulting in severe cholinergic nervous system function. disorder, and even endanger the respiratory and circulatory function and cause the poisoned person to die. The determination of c...

Patent No. 91229509.0 discloses a fast assay box for cholinesterase, which must use a battery, which is inconvenient to use and has a large volume. It also needs to be compared by a transparent thin plate. Even if the light transmittance of the transparent thin plate is very high, it will be more or less or little influence on the judgment of the test results
