Wrist strap self-locking type mobile electrocardiograph

Abstract

The invention belongs to the field of heart detection equipment and instruments. A wrist strap self-locking type mobile electrocardiograph comprises a testing host and a wrist strap body; the wrist strap body comprises a first wrist strap and a second wrist strap; the testing host is arranged on the first wrist strap; the second wrist strap is divided into two sections; the two sections of the second wrist strap are connected through a self-locking device; the self-locking device and the testing host are oppositely arranged; the first wrist strap is sleeved with the second wrist strap; a first spring is arranged in the first wrist strap and the second wrist strap; and one end of the first spring is connected with the first wrist strap, and the other end of the first spring is connected with the second wrist strap. The first wrist strap and the second wrist strap are arranged in a sleeved mode and connected together through the first spring, the first wrist strap and the second wrist strap can relatively slide, the wrist strap body can be always tightly attached to the wrist of a user under the action of the contraction elasticity of the first spring, and therefore a gap between the testing host and the wrist of the tester is eliminated, and the situation that the testing result is affected by external illumination is avoided.

Description

technical field [0001] The invention belongs to the field of heart detection equipment, and relates to an electrocardiograph, in particular to a wristband self-locking mobile electrocardiograph. Background technique [0002] With the increasing pressure of modern society and the aging society, cardiovascular disease has become a time bomb in people's body, and it is the number one factor causing people's death and injury. Since the clinical manifestations of most cardiovascular diseases are not obvious in the early or mid-term, once they are discovered, they often have reached the late stage. Therefore, the detection and prevention of cardiovascular diseases has become an important research direction. As one of the important criteria for testing cardiovascular diseases, heart rate variability has been widely used in clinical practice. [0003] The traditional detection method of heart rate variability is mainly to detect the change of heart rate after measuring the ECG sig...
