Needle-piercing blood sampler

Abstract

The invention provides a needle-piercing blood sampler. The needle-piercing blood sampler comprises a cylinder and a hollow syringe needle, the syringe needle comprises a needle point and a needle rod; one end of the cylinder is an opening end, and the other end of the cylinder is a fixing end; the fixing end fixes the syringe needle through the needle rod, the needle point of the syringe needle is located in the cylinder, and one part of the needle rod is located outside the cylinder. The needle-piercing blood sampler has the advantages that the structure is simple, the manufacture is convenient, when used, the operation is simple, and the amount of the blood taken is controllable.

Description

technical field [0001] The present application relates to a blood sampler, especially a needle blood sampler for sampling blood braids. Background technique [0002] Clinically, before using the blood in the blood bag to transfuse the recipient, it is necessary to use the blood braid on the blood bag to perform a blood matching test. For sampling from the blood braid, the current operation is to cut the blood braid with scissors to take blood, but this mode of operation has obvious disadvantages. First of all, it causes a large amount of blood to flow out from the blood braid, so that the scissors, the operating table, and even the operator's gloves are stained with blood, polluting the working environment. Secondly, the probability of cross-contamination is high. If the scissors are not thoroughly cleaned before the next use, it will cause sample crossover. However, cost and other conditions often do not allow for new scissors to be replaced each time. In addition, the bl...

For sampling from blood braids, the current operation is to cut the blood braids with scissors, but this method of operation has obvious disadvantages

First of all, it causes a large amount of blood to flow out from the blood braid, so that the scissors, the operating table, and even the operator's gloves are stained with blood, polluting the working environment

Secondly, the probability of cross-contamination is high. If the scissors are not thoroughly cleaned before the next use, it will cause sample cross-over, and the cost and other conditions are often not allowed for each replacement of new scissors.

In addition, the blood braid cannot be preserved after being cut, and when it is thrown away as waste, the remaining blood will also flow out, causing discomfort to the environment and people
