Intelligent hemostatic device capable of measuring pressure

Abstract

The invention belongs to the field of medical equipment, and particularly relates to an intelligent hemostatic device capable of measuring pressure, which comprises a tourniquet, a pressure sensor assembly and a digital display module, the pressure sensor assembly comprises a flexible pressure sensor and a protective sleeve; the digital display module comprises a human-computer interaction unit capable of setting module parameters, a signal processing unit for receiving and processing signals, a microcontroller for controlling the whole device, and a power supply and a power supply managementunit for monitoring the electric quantity. The flexible pressure sensor is ultrathin, good in flexibility, resistant to bending and capable of being bent freely, and devices of different shapes and different sizes can be designed according to different parts of a human body. The flexible pressure sensor has the characteristics of high density, flexibility, lightness, thinness, high fitness and thelike, can accurately detect the pressure of the tourniquet, and effectively solves the technical problems of low-cost real-time accurate measurement of contact interaction force and dynamic pressuredistribution of a narrow contact area of a non-planar interface.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an intelligent hemostasis device capable of measuring pressure. Background technique [0002] With the continuous development of medical technology, venous and arterial puncture has become a common clinical treatment technique. For the hemostasis problem after puncture, cotton swab pressing, manual finger pressure and bandaging were often used in the early stage. Later, someone proposed a tourniquet with pressure measurement function. The pressure sensor detects the pressure of the tourniquet on the wound. When the pressure is too large or too small, the tourniquet elastic mechanism is adjusted to adjust the pressure to an appropriate size. [0003] At present, common pressure measurement methods for tourniquets mainly include: directly measuring the pressure on the compression surface with a pressure or stress sensor, or measuring the air pressure inside t...
