Problems solved by technology
[0004] Existing peripheral blood collection devices mainly include blood collection needles and micropipettes. Medical personnel need to pinch and fix the patient's fingers with their fingers when collecting blood from patients, squeeze the fingers after acupuncture, and then use suction pipes to suck. The operation is very troublesome, time-consuming and laborious. , adding great difficulty to the medical staff

The invention belongs to the technical field of medical equipment and particularly relates to a terminal blood taking device comprising a blood taking needle and a micro pipette and also comprising a fixed plate, wherein two sides of the fixed plate are respectively and fixedly connected with an elastic arm; the fixed plate is provided with an air sac through hole and a button through hole; the air sac through hole is internally provided with an air sac; the sealed end of the air sac is located above the fixed plate, and the opened end of the air sac passes through the air sac through hole, extends to the downside of the fixed plate and is communicated with the micro pipette; the button through hole is internally provided with a blood taking needle button which passes through the button through hole and extends to the downside of the fixed plate; the part of the blood taking needle button, which is located above the fixed plate, is sleeved with a spring; and the bottom end of the blood taking needle button is movably provided with the blood taking needle. The terminal blood taking device is simple in structure, complete in function, convenient to use and capable of reducing the labor intensity of medical workers.
Description
technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a peripheral blood sampling device. Background technique [0002] In the daily work of the hospital, especially in the clinical laboratory, it is often necessary to take blood samples from patients for blood testing, and the hemoglobin testing is mostly performed by peripheral blood. [0003] At present, clinically, when collecting peripheral blood samples from patients, blood samples from the tip of the finger are mostly used. Now the commonly used method of peripheral blood collection is: the medical staff first gently massage the inner side of the patient's ring finger to make the local tissue congest naturally, use 75% Wipe the blood collection site with an alcohol cotton swab, and wait until it is dry. The medical staff fix the blood collection site with the thumb and index finger of the left hand to make the skin and subcutaneous tissue taut. Hold a disposable ste...
