Respiratory measurement bandage device and preparation method thereof

Abstract

The invention belongs to the technical field of medical devices, and in particular, relates to a respiratory measurement bandage device and a preparation method thereof. The respiratory measurement bandage device includes a signal processing module, a signal transmission module, a signal acquisition module and a bandage module; the bandage module is an annular bandage and is fixed in the abdomen of a subject; the signal acquisition module is a resistive stretch sensor made of a PDMS-graphene mixed material, is placed in the bandage and is used for acquiring respiratory signals; the signal processing module and the signal transmission module are connected with the bandage module through wires. The signal processing module is composed of a single chip microcomputer and corresponding peripheral electronic components. The signal transmission module adopts a dual-mode bluetooth module and transmits data through data transmission protocol. The signal acquisition module is connected to an ADconversion port of the single chip microcomputer through a voltage division circuit, one side of the signal acquisition module is connected to a voltage source VCC, the other side of the signal acquisition module is connected to an analog-to-digital converter self-carried by the single chip microcomputer in the signal processing module, and the change condition of respiration with time is obtained. The respiratory measurement bandage device has high measurement accuracy and is safe and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a respiration measuring bandage device and a preparation method thereof. Background technique [0002] Respiratory monitoring is one of the important means to evaluate human health status. Nearly 5% of the population suffers from respiratory diseases such as sleep apnea syndrome. Respiratory disease has been reported in approximately 30 percent of the population aged 70 years in industrialized countries [1]. Dynamic monitoring of sleep breathing status plays an important role in the diagnosis and treatment of sleep apnea, sudden death syndrome and other sleep disorders [2]. Over the past decade, new home monitoring respiratory monitoring devices have grown in popularity due to the psychological stress that hospital environments can cause [3]. [0003] Current techniques for monitoring respiration (obtaining respiratory rate) include chest electrical impedan...

Problems solved by technology

However, the fabrication method of the induction strip of the device is complicated and difficult to be embedded in other wearable devices

At present, the respiration measurement method is used clinically, and long-term use will bring the following problems: (1) Since the electrode material in the thoracic electrical impedance does not have air and moisture permeability, long-term use will cause skin discomfort; (2) The three-dimensional accelerometer and pressure Electrical sensors are susceptible to motion trails; (3) Existing breathing straps are complicated to manufacture and difficult to embed into other wearable devices
