Collector with micro quantitative sampling and sample adding function

Abstract

The invention discloses a collector with a micro quantitative sampling and sample adding function. The collector comprises a sampler and a quantitative container bottle, wherein the sampler comprises a hollow air sac handheld part, an air sac external circular surface at the bottom of the air sac handheld part; a liquid suction head external circular surface sleeving the air sac external circular surface and a capillary liquid suction head located at the bottom of the liquid suction head external circular surface; the quantitative container bottle comprises a container bottle bottom through hole, a twisting part, a truncation surface of the twisting part, and a convex locating ring; the capillary liquid suction head comprises capillaries, a through hole for siphoning liquid, a capillary external circle suction head, and a capillary section used for controlling the precision of sucked liquid; when the sampler is inserted into the quantitative container bottle, the convex locating ring is exactly matched with the liquid suction head external circular surface, so that the interior of the quantitative container bottle is sealed. According to the invention, the collector combines the two functions of the micro precision sampling and micro exact transfer filling to realize accurate sampling and sample adding.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a collector for one-time micro-quantitative sampling and quantitative addition of one liquid or multiple liquids. Background technique [0002] Disposable micro-quantitative sampling and adding samplers are currently widely used in the medical industry. With the continuous development of the medical testing industry, there are more and more applications for disposable micro-quantitative sampling and quantitative sampling. Currently on the market There are mainly two methods of quantitative sampling. One is the siphon-type micro quantitative capillary with scale. Although it can sample, the accuracy of sampling during the operation has a lot to do with the method of operation, and it is difficult to be accurate. One is a micro-quantitative capillary sampler. Although the sampling is very accurate, it is difficult for these two samplers to add samples accurately. Or in...

[0002] Disposable micro-quantitative sampling and adding samplers are currently widely used in the medical industry. With the continuous development of the medical testing industry, there are more and more applications for disposable micro-quantitative sampling and quantitative sampling. Currently on the market There are mainly two methods of quantitative sampling, one is the siphon micro quantitative capillary with scale, although it can sample, but the accuracy of sampling in the process of operation has a lot to do with the way of operation, it is difficult to be accurate

One is the micro-quantitative capillary sampler. Although the sampling is very accurate, it is difficult for these two samplers to accurately add samples.

Or in the transfer and filling of mixed samples, the steps are cumbersome, the accuracy cannot be controlled, and the different operating methods have a great impact on the results. Therefore, there is an urgent need for an accurate sampling, mixing and sample transfer and filling that is simple to operate. Simple and fast, precise quantitative equipment
