Pressure measuring device for pressure bandage point positions

Abstract

The invention discloses a pressure measuring device for pressure bandage point positions. The device comprises a plurality of pressure sensors arranged at different point positions of a pressure bandage, filter shaping circuits in one-to-one correspondence with the pressure sensors, an MCU circuit, a battery, a step-down circuit, a charging protection circuit, a USB interface circuit, an LCD circuit, a display and a FLASH circuit. The pressure sensors detect pressure signals of corresponding point positions, the filter shaping circuit filters and shapes the pressure signals into analog voltagesignals and transmits the analog voltage signals to the MCU circuit, and the MCU circuit obtains a corresponding pressure value based on the analog voltage signals, transmits the obtained pressure value to the display for display through the LCD circuit and stores the pressure value to the FLASH circuit. The step-down circuit performs voltage reduction and stabilization on the voltage of the battery and transmits a voltage stabilization signal to the MCU circuit. The MCU circuit controls the USB interface circuit to charge the battery and controls the charging protection circuit to perform charging protection on the battery.

Description

Technical field [0001] The invention relates to the technical field of pressure monitoring, in particular to a pressure bandage point pressure measuring device. Background technique [0002] Patients with venous ulcers or lymphedema of the lower limbs need to be treated with pressure. Pressure bandages are generally used, and pressure control is entirely based on the subjective judgment and proficiency of the bandaging nurse. Patients will dismantle themselves because they feel uncomfortable with tightness, while nurses cannot obtain a relatively accurate pressure assessment through objective numbers or remote monitoring. In order to prevent extremity necrosis caused by excessive pressure, they will agree to the patient’s self-determination. tear down. In addition to not having its due effect, demolition will also cause problems with patient compliance and nurse-patient trust. Summary of the invention [0003] Aiming at the problems and deficiencies in the prior art, the present...

AI Technical Summary

Problems solved by technology

The patient will remove it by himself because of the discomfort of the tightness, and the nurse cannot obtain a relatively accurate pressure assessment through objective numbers or remote monitoring. In order to prevent necrosis of the extremities caused by excessive pressure, the patient will agree tear down

In addition to failing to play its due role, demolition will also cause problems in patient compliance and nurse-patient trust.
