Automatic quantitative blood sampler

Abstract

The invention provides an automatic quantitative blood collection device and relates to the technical field of medical instruments. The automatic quantitative blood collection device comprises a pedestal and a support arm fixed on the pedestal. The support arm is provided with a plurality of syringe needle fixing bases, blood collection tube fixing clamps and a tube flow control device, wherein the blood collection tube fixing clamps are corresponding to the syringe needle fixing bases in a one-to-one manner, and the syringe needle fixing bases and the blood collection tube fixing clamps are arranged on the support arm in a spaced manner horizontally. The automatic quantitative blood collection device also comprises an automatic control system which can control the blood collection quantities of blood collection tubes in real time. The automatic control system communicates with the tube flow control device. The syringe needle fixing bases and the blood collection tube fixing clamps can clamp and fix a plurality of blood collection syringe needles and blood collection tubes at the same time, so that the blood collection tubes can collect blood simultaneously and the blood collection efficiency is increased; the automatic control system can control the tube flow control devices, so that the blood collection quantities can be automatically and accurately controlled and the accuracy of the blood collection quantities is greatly improved; blood collection requires no manual intervention, so that the labor intensity of people is reduced and the blood collection efficiency is further increased.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a blood sample collector capable of automatic and accurate quantitative collection. Background technique [0002] The collection of blood samples is common, and the amount of blood samples required for different laboratory items may be different. When collecting blood samples, medical staff basically determine the collection volume based on the negative pressure in the blood collection tube and the scale of the blood collection tube. Test results. [0003] In order to avoid the above problems, most medical staff adopt the principle of preferring to draw more and never less. Therefore, there are problems of excessive collection and waste. At the same time, most patients feel distressed that their blood is drawn out, especially when they are critically ill. Severe patients think that a drop of blood is precious, which can easily lead to problems between doctor...
