Blood collection device for hematology department

Abstract

The blood collection device for the hematology department comprises a cylinder body, an end cover, a sliding rod, an elastic sleeve, a spring, a connecting plate, a second mounting plate and a clamping part, a placing frame for placing a plurality of groups of blood collection tubes is arranged in the cylinder body; the end cover is connected with the cylinder in a matched mode and provided with multiple sets of first through holes. A fixing plate is arranged at one end of the sliding rod which is rotationally connected with the end cover through a rotating shaft; a first mounting plate is slidably arranged on the sliding rod; the spring sleeve and the elastic sleeve are arranged on the outer side of the sliding rod and connected with the first mounting plate and the fixing plate correspondingly. The clamping part comprises a first clamping block and a second clamping block; the first clamping block and the second clamping block are detachably connected and used for clamping the tail needle of the blood taking needle. Two ends of the connecting plate are respectively connected with the first mounting plate and the second mounting plate; a plurality of sets of fastening assemblies used for fastening the clamping parts are arranged on the second mounting plate. The device is easy to operate and convenient to use, medical staff can be assisted in blood drawing of a patient, and the medical staff can be prevented from being hurt by a blood sampling needle.

Description

technical field [0001] The invention relates to the technical field of blood collection, in particular to a blood collection device for hematology. Background technique [0002] Blood is an opaque red liquid flowing in the heart and blood vessels. Blood contains various nutrients and stores human health information. Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, and bone marrow cytology. Detection, blood type identification and cross-matching experiments can detect the hematological characteristics of common blood diseases; when patients undergo examination in the hospital, they often need to collect blood for laboratory tests; some of the following contents can be detected through blood testing, alanine amino Transferase, hepatitis C virus antibody, HIV antibody, and syphilis tests, etc.; when taking blood samples from patients, it is necessary to manually pull out the tail needle of the blood collection needle and inser...

[0002] Blood is an opaque red liquid flowing in the heart and blood vessels. Blood contains various nutrients and stores human health information. Clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, and bone marrow cytology. Detection, blood type identification and cross-matching experiments can detect the hematological characteristics of common blood diseases; when patients undergo examination in the hospital, they often need to collect blood for laboratory tests; some of the following contents can be detected through blood testing, alanine amino Transferase, hepatitis C virus antibody, HIV antibody, and syphilis tests, etc.; when taking blood samples from patients, it is necessary to manually pull out the tail needle of the blood collection needle and insert it into the next set of blood collection tubes. Manual operation makes blood collection easier. The tail of the needle will cause harm to medical staff; unskilled medical staff need to spend more time switching blood collection tubes, which will greatly increase the exposure time of the tail needle of the blood collection needle in the air, and germs and impurities in the air are easy to attach to the blood collection needle On the tail needle, which affects the accuracy of blood testing
