Abstract

The invention relates to the field of medical supplies, in particular to a special traceless-tourniquet blood collection assistor for the department of hematology. The assistor comprises a bottom plate, a gripping component, a tourniquet bag tightening component, a stroke increasing component and the like, wherein the gripping component is arranged on the bottom plate, the tourniquet bag tightening component is arranged on the bottom plate, and the stroke increasing component is arranged on the gripping component. By means of an inflatable cotton tape, no indentation is generated on an arm of a patient in a pulse pressing process of the arm of the patient, so that subcutaneous blood stasis generated on the arm of the patient can be avoided, the suffering of the patient can be prevented from being increased, and the effect that subcutaneous blood stasis generated on the arm of the patient can be avoided to prevent secondary damage to the patient is achieved.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to an auxiliary device for blood collection without trace puncture for hematology. Background technique [0002] The method of drawing a certain amount of venous blood through a needle tube is called venous blood collection. Before blood collection, it is usually necessary to make the patient sit in front of the table, put the patient's arm on the table, and make the palm upward, and put a pillow under the arm. It is difficult to confirm the veins on the patient's arm, so it is necessary to press the patient's arm to make the veins on the patient's arm appear, so as to facilitate subsequent blood collection. [0003] In the prior art, the patient's arm is fastened tightly through a rubber tube, so that the veins on the patient's arm appear, and then the blood is drawn directly from the patient using a blood drawing needle. Too many, repeatedly tied the cuff will make the operation e...
