Blood drawing and hemostasis pressurizing device for clinical laboratory

Abstract

The invention provides a blood drawing and hemostasis pressurizing device for clinical laboratory, the blood drawing and hemostasis pressurizing device comprises a fixing frame, a pressing mechanism is movably connected in the fixing frame, the pressing mechanism comprises a positioning assembly used for supporting and fastening two sides of an arm during blood drawing and a compacting assembly used for pressurizing the top of the arm, the positioning assembly is movably connected in the fixing frame, and the compacting assembly is used for compacting the top of the arm. The compaction assembly is movably connected to the interior of the fixing frame. A placing plate slides to enable a sliding rod to slide to drive a side plate to slide, the side plate slides to rapidly fix, limit and clamp the two sides of the arm of a patient, meanwhile, a first gear rotates to enable an arc plate to rotate, the arc plate rotates to enable a pressure plate to press the arm, then arm blood vessels are rapidly highlighted, and accurate control over blood drawing pressing force is also improved; meanwhile, arm blood is sucked in through the air pipe and conveyed into the storage chamber, then efficient hemostasis cleaning is achieved, and the safety and sanitation of blood drawing are improved.

Description

technical field [0001] The invention relates to the technical field of blood detection, in particular to a blood drawing and hemostasis pressurization device for laboratory. Background technique [0002] Blood drawing generally refers to taking venous blood. Except for special requirements, venous blood tests generally require blood drawing in the morning. Before blood drawing, try to reduce the amount of exercise, do not eat food, keep an empty stomach, and drink a small amount of water. Some experimental results have been interfered with. After blood is drawn, under normal circumstances, the bleeding caused by damage to small blood vessels will stop automatically within a few minutes. This phenomenon is called physiological hemostasis. Physiological hemostasis is one of the important protective mechanisms of the body and is the result of the interaction of various factors and mechanisms. The hemostasis process mainly includes three processes of vasoconstriction, platelet ...

Problems solved by technology

[0003] In order to solve the above-mentioned existing problems in blood drawing, it is necessary to tie and squeeze the patient's arm through the tie to make the blood vessels stand out, which is convenient for the doctor to draw blood. To achieve precise control, it is not convenient for doctors to observe whether the blood vessels are prominent, which reduces the efficiency of blood drawing. At the same time, the patient’s arm has bleeding after bleeding, and he cannot quickly press to stop the bleeding and clean up the blood. , high-efficiency hemostatic cleaning, time-saving and labor-saving, and precise pressure control purposes, the present invention is achieved through the following technical solutions: a blood drawing and hemostasis pressurization device for laboratory, including a fixed frame, and the internal movable connection of the fixed frame has Pressing mechanism, the pressing mechanism includes a positioning assembly for supporting and fastening both sides of the arm for drawing blood, and a compacting assembly for pressing the top of the arm, the positioning assembly is movably connected to the inside of the fixed frame, and the compacting assembly The movable connection is inside the fixed frame
