Wristband self-locking type mobile electrocardiograph

Abstract

A wrist strap self-locking winding structure is fixedly assembled in a wrist strap winding box, a micro motor is fixedly assembled on the left side of the rear wall of an inner cavity of the wrist strap winding box, a rotating rod is fixedly assembled at the output front end of the micro motor, and a wrist strap is fixedly connected to the left side wall of the wrist strap winding box; the right end of the wrist strap penetrates through the wrist strap access through hole structure and is fixedly wound on the outer side of the rotating rod; a flexible pressure sensor is embedded in the upper surface of the wrist strap; according to the wrist strap self-locking winding structure, a flexible pressure sensor is pressed through an arm, the flexible pressure sensor transmits an electric signal to a controller, the controller is used for controlling a micro motor to rotate, the micro motor rotates to wind and wind a wrist strap, and automatic winding of the wrist strap is achieved; when the wrist strap is wound to hoop the arm, the pressure of the flexible pressure sensor reaches a preset value, the electric signal is transmitted to the controller again, the controller controls the micro motor to stop rotating, and self-locking of the wrist strap is achieved.

Description

technical field [0001] The invention relates to the technical field of mobile electrocardiographs, in particular to a wristband self-locking mobile electrocardiograph. Background technique [0002] An electrocardiogram is a technique that uses an electrocardiograph to record from the body surface the patterns of electrical activity changes produced by the heart during each cardiac cycle. An electrocardiogram is the best method for measuring and diagnosing abnormal heart rhythms. Abnormal rhythm and changes in heart rhythm due to electrolyte imbalance. [0003] The myocardial cell membrane is a semi-permeable membrane. In the resting state, a certain number of positively charged cations are arranged outside the membrane, and the same number of negatively charged anions are arranged inside the membrane. The potential outside the membrane is higher than that in the membrane, which is called a polarized state. In this state, since the cardiomyocytes in all parts of the heart ar...

Problems solved by technology

[0004] Although the existing portable ECG graphing instrument is called portable, it is not perfectly portable. It is still a separate individual, and its volume is still relatively large. It cannot be quickly adjusted according to the body of different wearers, and it is very inconvenient to carry. , in order to solve the above problems, we propose a wristband self-locking mobile electrocardiograph
