The blood drawing auxiliary device comprises atank. The front end surface and the rear end surface of the tank are communicated with each other, a second line roller is fixedly connected with the rear end surface of a first line roller, a thirdline roller is fixedly connected with the side, which is far away from the first line roller, of the second line roller, a rotary rod is fixedly connected with a certain side of each of the first lineroller and the third line roller, the certain side of the first line roller and the certain side of the third line roller are far away from the second line roller, the two rotary rods are positionedat the same horizontal altitude, a support plate is movably connected with the end, which is far away from the second line roller, of each rotary rod and is fixedly connected to the top of the tank, aflat spiral spring is arranged on a certain side of each of the first line roller and the third line roller, the certain side of the first line roller and the certain side of the third line roller are far away from the second line roller, the top of the end, which is far away from a pedal, of a third rope penetrates the top of the tank, and the third rope is wound on the third line roller. The blood drawing auxiliary device for the departments of hematopathology and the method have the advantages of high efficiency, simplicity in operation and the like.

Description

technical field [0001] The invention relates to the technical field of hematology supplies, in particular to a blood drawing auxiliary device for hematology and a method for using it. Background technique [0002] Hematology, also known as hematology, is a branch of internal medicine, which mainly treats diseases of the hematopoietic system, that is, blood diseases. In some hospitals, it is often included in the Department of Oncology, collectively referred to as the Department of Oncology and Hematology. Generally, in medical treatment, when a nurse is looking for intravenous infusion or blood collection, a rubber tube is tightened to fill the blood volume and then the vein appears. That tube is called a tourniquet, also called a cuff. The purpose of applying the cuff is to increase the local filling of the vein, which is conducive to puncture. The correct operation is to fasten the cuff first, then observe the direction of the blood vessels, loosen the cuff in time, and ...
