Automatic pulse pressing device for blood drawing

Abstract

Disclosed is an automatic pulse pressing device for blood drawing. The automatic pulse pressing device for the blood drawing comprises a housing (1), medical latex tubes (4), two rotation wheels (5), a motor (6), sensors (7) and a control system (8), wherein an arm placing through hole (2) and a positioning groove (3) are formed in the housing (1), the medical latex tubes (4) are crosswise fixed in the positioning groove (3), two ends of each medical latex tube (4) are respectively fixed on the two rotation wheels (5), the two rotation wheels (5) are respectively connected with the motor (6), and simultaneously rotate, one of the two rotation wheels (5) can be fixed, the other rotation wheel can be rotated, the sensors (7) are installed on the medical latex tubes (4), and can not touch the rotation wheels (5) within the maximum stroke, and the motor (6) and the sensors (7) are all connected onto the control system (8). Simultaneously, the automatic pulse pressing device for the blood drawing is further provided with a collection point indication lamp (9), and the collection point indication lamp (9) is fixed on the upper portion of the front end of the housing (1) through a hose (10). The automatic pulse pressing device for the blood drawing is simple in structure and strong in practicability, achieves automatic pulse pressing for an arm which is placed in the arm placing through hole (2), can reduce workloads and decrease the number of work procedures for nurses, and quickly and accurately finds out positions of blood vessels, and thereby improves medical care work efficiency and quality.

Description

technical field [0001] The invention relates to a medical auxiliary tool, in particular to the structure of an automatic blood pressure device for drawing blood. Background technique [0002] For a long time, in daily clinical venous blood collection, whether it is organizing a physical examination or when the nurses in the outpatient department of the hospital are responsible for blood collection, they have repeated the same work, using rubber tubes to bind the arms, and then using needles to find blood vessels, which is time-consuming , and there are problems such as heavy workload, complicated procedures, and difficult to find blood vessels, which not only bring a lot of inconvenience to their work, but also increase the suffering of patients. [0003] Therefore, need to be improved, develop a kind of device that is used for the automatic binding of cuff when venous blood is collected, and has venous indication function. Contents of the invention [0004] The present i...
