Problems solved by technology

[0003] When checking the formula of traditional Chinese medicine in the traditional Chinese medicine medical center, the traditional Chinese medicine preparation will be boiled according to the proportion required by the formula, and the time and proportion of boiling will be different to form a variety of different medicines, and then the medicines will be taken out through a pipette for comparison and laboratory tests, but traditional Chinese medicine centers use the naked eye to observe the suspended matter and color for detection and comparison. Professional electronic pipettes on the market are relatively expensive, and small-scale medical centers are rarely equipped with such equipment. Traditional needle tubes, in the When aspirating liquid, on the one hand, two hands are required to perform the liquid aspiration operation together; on the other hand, there are many suspended solids in the traditional Chinese medicine reagent, which is easy to cause the problem of blockage of the needle tube, so it is not conducive to practical use

Abstract

The invention discloses a pipettor for traditional Chinese medicine detection, and particularly relates to the field of traditional Chinese medicine detection; the pipettor comprises external liquid suction cylinder mechanisms, and a pressing type piston support mechanism is slidably inserted into an inner cavity of each external liquid suction cylinder mechanism; middle-arranged air pressure typepiston rod mechanisms are inserted into inner cavities of the external liquid suction cylinder mechanisms and inner cavities of the pressing type piston supporting mechanisms in a sliding mode, a plurality of external liquid suction cylinder mechanisms are arranged, and a plurality of connecting type semicircular clamping mechanisms are connected between the plurality of external liquid suction cylinder mechanisms in a clamped mode. By arranging the middle-arranged air pressure type piston rod mechanisms, after being pushed by air pressure, a sealed cambered surface air pressure plate in an inner cavity of a second annular piston movable groove drives an air pressure type sliding piston rod to slide upwards, so that the convenience of manual suction of traditional Chinese medicine reagents is relatively improved, and meanwhile, the whole device is disposable equipment. Therefore, the use cost of a traditional Chinese medicine museum is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine detection, and more specifically, the invention relates to a pipette for traditional Chinese medicine detection. Background technique [0002] Drugs that are collected, processed and prepared under the guidance of traditional Chinese medicine theory, explain the mechanism of action, and guide clinical application are collectively referred to as traditional Chinese medicine. As substances for rehabilitation and health care, traditional Chinese medicine mainly comes from natural medicines and their processed products, including herbal medicines, animal medicines, mineral medicines and some chemical and biological products. As the saying goes, a pipette is also called a pipette gun. It is a measuring tool that transfers liquid from the original container to another container within a certain range. It is widely used in biology, chemistry and other fields. , the clinically common...
