Abstract

The invention relates to the technical field of medical equipment, in particular to a blood sampling auxiliary device which comprises a base, a tightening seat and a hemostasis assembly. The tightening seat is arranged at one end of the base. The tightening seat is provided with a through hole for an arm to pass through. The tightening seat is provided with a tightening assembly matched with the through hole and used for tightening the arm. The base is used for placing an elbow. The hemostasis assembly comprises a winding wheel, an unwinding wheel and a pressing piece. The unwinding wheel is matched with the tourniquet roll. The winding wheel is used for winding the tourniquet of the tourniquet roll. The pressing piece is used for pressing the tourniquet to the arm. The patient's hand passes through the through hole and the elbow lies flat above the base. The tightening assembly acts and tightens the arm. In this way, the arm of the patient is fixed, and the arm is prevented from moving in the blood sampling process. After blood sampling is completed, the winding wheel and the square winding wheel act cooperatively, so that the tourniquet moves to the front end of the pressing piece. the tourniquet can be adhered to the puncture part of the arm by the action of the pressing piece, so that the hemostasis action is completed.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a blood collection auxiliary device. Background technique [0002] During the treatment of diseases, it is often necessary to collect blood from patients. The existing blood collection method usually uses pads and tightening bands to assist the blood collection work. During the blood collection process, the doctor puts a compression band on the arm and then punctures the arm to draw blood. After finishing, press the cotton swab to stop the bleeding. Finally, the patient needs to press the cotton swab for a few minutes to stop the bleeding. This makes it necessary to prepare various props every time when blood is collected, and the doctor has many steps in the blood collection process, and the blood collection efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a blood collection auxiliary device, which c...
