A blood collection device

Abstract

The invention discloses a multifunctional blood collection device suitable for collecting trace blood samples, which comprises a blood collection tube and a seal; the seal is installed on the blood collection tube, and the vacuum blood collection by venipuncture is realized through the seal; the blood collection tube is divided into a blood collection part and a collection part , the blood collection part is provided with a guide tube port, and the guide tube port is provided with an outer edge and a drainage slope to guide the liquid into the collection part for collection; the bottom of the collection part is closed. The present invention is used to collect venous blood when the seal is connected to the blood collection tube, and realizes peripheral blood collection when the blood collection part is separated from the seal. Matched with the upper machine instrument, it realizes multi-functional blood collection and standardized processing.

Description

Technical field [0001] The present invention relates to the field of blood collection techniques, and in particular, a multi-functional blood collection device suitable for trace blood sample collected. Background technique [0002] In recent years, with the development of medical technology, the application of vacuum blood collection test tubes in clinical blood test is also more extensive. According to the clinical needs, the vacuum blood collection tube can be divided into many types, such as ethylenediamine tetracetate (EDTA) anticoagulant, heparin tube, blood coagulation, and laminating tube, etc.. In implementing the present invention, the inventors have found that the prior art is at least as follows: [0003] During clinical diagnosis and treatment, the clinical laboratory usually needs to extract a large number of blood from the patient, but there is still more blood collection disorders in practice, such as small samples, hemolysis , Blood splash, excessive residual neg...

Problems solved by technology

However, for some special groups that are anemic or difficult to collect venous blood, the use of vacuum blood collection tubes for blood collection cannot achieve good results, and blood hemolysis is often caused by excessive residual negative pressure in the tube, which affects the detection progress

For infants and young children, due to the particularity of blood vessels and blood cells, it is difficult to ensure sufficient venous blood collection, and excessive blood collection may even easily cause iatrogenic anemia, so there is still a need for peripheral blood collection in clinical practice

[0005] It is worth mentioning that common micro-volume distal tubes are difficult to meet the requirements of existing automatic labeling and on-machine instruments, and often require a lot of manual operations, which affects the efficiency of blood collection, and repeated opening of the cap is likely to cause biological contamination. However, the currently used Vacuum blood collection tubes cannot meet the requirements of venous and peripheral blood collection at the same time
