Safe detection system, safe detection method, non-invasive blood pressure measuring device and safe protection method

Abstract

The invention provides a safe detection system for a non-invasive blood pressure measuring device; the system comprises a cuff type identification module; the cuff type identification module is used for receiving a cuff pressure signal and calculating a cuff internal pressure rising speed value through the cuff pressure signal; and the cuff internal pressure rising speed value is compared with the maximum pressure rising speed value of a corresponding patient type, so that whether a corresponding patient uses the correct type of non-invasive blood pressure measuring device or not is known. The invention has the beneficial effects that the cuff type identification module detects the cuff internal pressure rising speed in actual measurement and compares the cuff internal pressure rising speed in actual measurement with the maximum pressure rising speed value corresponding to the patient type selected by a user; when the actual patient type is inconsistent with the actual patient type tested by the non-invasive blood pressure measuring device, the safe detection system can find in time, so that the safety of the user in using the non-invasive blood pressure measuring device is ensured.

Description

technical field [0001] The invention relates to medical equipment, in particular to a safety detection system and method, a noninvasive blood pressure measurement device and a safety protection method. Background technique [0002] Most noninvasive blood pressure measurements use the oscillation method. This method also requires blocking the arterial blood flow with a cuff like the traditional "Krotkoff-sound method". However, during the deflation process, instead of detecting Korotkoff sounds, the pressure sensor detects the oscillation wave of the gas in the sleeve. These oscillating waves originate from the vibration of the arterial vessel wall. This oscillating wave has a certain functional relationship with the arterial wall systolic pressure, diastolic pressure, and mean pressure. After the oscillation wave is amplified and filtered, the envelope is detected, and then the corresponding relationship between the envelope and systolic blood pressure and diastolic blood...

Problems solved by technology

The patient type of the non-invasive blood pressure measurement device needs to be manually set by the user. In actual use, the user may set the patient type incorrectly or forget to change the patient type, resulting in the actual patient type being different from the actual patient type tested by the non-invasive blood pressure measurement device. inconsistent

For example, the user mistakenly selects the adult mode when measuring non-invasive blood pressure, and the cuff used by the actual test patient is a newborn cuff, and if there are no protective measures at this time, it will cause harm to the test patient
