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

Abstract

The invention discloses a multifunctional blood collection device suitable for collection of a trace blood sample. The device includes a blood collection tube and a sealing member, wherein the sealingmember is installed on the blood collection tube, venous puncture and vacuum blood collection are realized through the sealing member, and the blood collection tube is divided into a blood collectionsection and a collection section; and a blood guide tube mouth is formed in the blood collection section, the blood guide tube mouth is provided with an outer edge and a flow guide slope which are used for guiding a liquid into the collection section for collection, and the bottom of the collection section is closed. Venous blood is collected when the sealing member is connected with the blood collection tube, peripheral blood collection is achieved when the blood collection section is isolated from the sealing member, so that needs of venous blood collection and peripheral blood collection are met at the same time, the multifunctional blood collection device is matched with an existing automatic labeling on-line machine, and multifunctional blood collection and standardized processing are achieved.

Description

technical field [0001] The invention relates to the technical field of blood collection, in particular to a multifunctional blood collection device suitable for collecting trace blood samples. Background technique [0002] In recent years, with the development of medical technology, the application of vacuum blood collection test tubes in clinical blood tests has become more and more extensive. According to clinical needs, vacuum blood collection tubes can be divided into many types according to different additives, such as ethylenediaminetetraacetate (EDTA) anticoagulant tubes, heparin tubes, blood coagulation tubes, procoagulant tubes and so on. In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0003] In the process of clinical diagnosis and treatment, due to the needs of various blood tests and monitoring treatment effects, clinical laboratories usually need to draw a large amount of b...
