Description

Automatic quantitative hemostix

Technical Field

The invention relates to the technical field of blood collection, in particular to an automatic quantitative blood collector.

Background

The collection of blood samples generally exists, the blood sample amount required by different assay projects may be different, when the blood samples are collected, medical staff generally determines the collection amount according to the negative pressure in the blood sampling tube and the scale of the blood sampling tube, and the blood sampling needle is matched for blood sampling or blood sampling, the blood sampling needle for blood sampling mostly comprises disposable blood sampling needles consisting of two needles and a middle hose, wherein one needle is inserted into the blood vessel of a patient or a blood storage flat, and the other needle is inserted through a sealing head at the top of the blood sampling tube for blood sampling, but the negative pressure is often inaccurate, the scale mark is not obvious, and the blood sampling tube is inclined, so the blood sampling amount is extremely inaccurate, and the detection result can be influenced; in order to avoid the problems, most medical staff adopt the principle of more and more pumping and more and less pumping, so that the problems of excessive collection and large waste exist, and the doctor-patient problem is easily caused.

In summary, the automatic quantitative blood collector has the defects that continuous and stable suction is inconvenient, and the blood collection tube is not convenient to be fixed in an anti-inclination mode rapidly (mainly embodied in that the initial negative pressure in the blood collection tube is large, the suction force is strong, pain is brought to a patient, and the negative pressure is reduced along with the entering of blood, so that subsequent suction is weak), and the quantitative judgment is influenced by the inclination of the blood collection tube, so that the use requirement cannot be met.
