Problems solved by technology
However, in the existing venous blood collection operations, medical staff hold blood collection tubes for sampling, and in many cases, multiple blood samples need to be collected for multiple items in one test. This operation of directly pinching blood collection tubes for blood collection brings many problems.
[0004] First of all, because the blood collection personnel have gloves on their hands, it is not easy to repeatedly pick up and put down the thinner blood collection tubes, the success rate is not high at one time, and it is easy to slip, squeeze out, etc. , collision and other issues
It also greatly affects the continuity of blood collection and reduces the efficiency of blood collection
[0005] In addition, the temperature of the palm of the blood collection personnel varies greatly, and the blood collection tube wall is continuously touched during the grasping process. When the blood is slowly drawn out and inflowed, the overcooling or overheating of the palm will have a negative impact on the sample.

The invention discloses a handheld anti-interference fixing device for blood collection and mainly relates to the field of medical inspection sampling instruments. The fixing device comprises a plurality of sector-shaped modules which are hinged to one another in sequence, containing cavities are formed in the sector-shaped modules, vertical fixing sleeves are fixed in the containing cavities, arc-shaped elastic pieces are arranged in each fixing sleeve in an annular array, the inner sides of the arc-shaped elastic pieces are rolled up, and the sector-shaped modules at both ends are provided with a thumb lantern ring and a four-finger lantern ring respectively. The fixing device has the advantages that potential risks of infecting the viscera with bacteria due to replacement of blood collection tubes are avoided, the consistency and efficiency of blood collection are greatly improved, and the quality of sample collection is ensured.
Description
technical field [0001] The invention relates to the field of medical testing and sampling instruments, in particular to a hand-held anti-interference fixer for blood collection. Background technique [0002] In medical testing, collecting blood samples is the basic link of many medical testing projects. Vacuum blood collection tube is a kind of vacuum negative pressure blood collection tube. The extensive use of automated instruments and the preservation of blood put forward higher requirements for the stability of the original properties of blood samples, making vacuum blood collection technology break through the requirements only for safety, and its accuracy , The original properties of the specimen, the maintenance time, the cooperation of the tube and the machine, and the strength of the test tube can all be used as the basis for evaluating the quality of the vacuum blood collection tube. The existing common blood collection tubes mainly include heparin tubes, blood co...
