A kind of blood sampler for medical laboratory

Abstract

The invention discloses a blood sampler for medical laboratory, which comprises a sampling tube and a material storage tube. A sampling needle is installed at the lower end of the sampling tube, and a material outlet is opened at the lower end of the sampling tube. The lower end is provided with a mounting seat, and a feeding hole is opened on the mounting seat, and the lower end of the mounting seat is installed with a resisting pipe, and the lower end of the resisting pipe is provided with an overflow hole; the side wall of the mounting seat is inserted There is a rotating rod, one end of the rotating rod extends into the feeding hole and is fixedly connected with a blocking sphere, the blocking sphere is provided with a communication hole, and the other end of the rotating rod penetrates the mounting seat and is welded with a knob; The upper end of the storage tube is provided with a circular through hole. The advantage is that the present invention has a clever structure, and when blood is drawn and moved into the storage tube, the contact between blood and air is isolated, the result of blood sugar detection by external factors is minimized, and the accuracy of blood detection result is ensured.

Description

technical field [0001] The invention relates to the technical field of medical testing, in particular to a blood sampler for medical testing. Background technique [0002] A blood sampler is an instrument for taking blood samples. With the development of medical technology, blood sampling checks are becoming more and more common. However, traditional blood samplers cannot meet the needs of modern medicine. Moreover, when the traditional blood sampler draws a blood sample, the situation of blood sucking back caused by the inconsistency of pressure often occurs, which makes the patient's blood sampling site swollen and painful, seriously affects the sampling speed, and makes the patient more painful. In the collection process of blood testing, ordinary test tubes are often used for collection and storage. In the process of collection, storage and testing, insufficient attention is paid to the temperature change of blood samples and the oxidation caused by exposure to air, espe...

[0002] Blood sampler is an instrument for drawing blood samples. With the development of medical technology, blood sampling checks are becoming more and more common. However, traditional blood samplers cannot meet the needs of modern medicine.

Moreover, when the traditional blood sampler draws blood samples, blood sucking back often occurs due to the inconsistency of the pressure, which makes the patient's blood sampling site swollen and painful, seriously affects the sampling speed, and makes the patient more painful.

In the collection process of blood testing, ordinary test tubes are often used for collection and storage. In the process of collection, storage and testing, insufficient attention is paid to the temperature change of blood samples and the oxidation caused by exposure to air, especially for For the inspection of some trace and easy-to-oxidize indicators, such a sampling method often causes a large deviation in the test results, which is not conducive to clinical judgment and even leads to misjudgment
