Oximeter and working method thereof

Abstract

The invention provides an oximeter and an operating method thereof. The method comprises steps of starting a measurement unit to measure correlation parameters and stopping supply of power to communication units when measuring the correlation parameters; processing the correlation parameters; judging whether to transmit the processed correlation parameters or not; if so, transmitting the processed correlation parameters. According to the invention, energy expenditure of the oximeter can be reduced and the working time of the oximeter can be prolonged because the supply of power to communication units is stopped in the measuring period.

Description

technical field [0001] The present invention relates to medical testing equipment, in particular to an oximeter, and in particular to an oximeter and its working method. Background technique [0002] As a commonly used medical testing equipment, the oximeter is used to measure the blood oxygen saturation and pulse rate of the human body. [0003] Current oximeters mainly include monitors, such as monitors used in intensive care units such as ICU and CCU in hospitals. After the patient's blood oxygen saturation and pulse rate are received by the sensor, they are transmitted to the monitor through the wire, and the monitor performs real-time display, storage and analysis after receiving the data. The invention patent application with the patent number ZL97196522.6 discloses a digital oximeter. Figure 1A is a schematic diagram of a digital oximeter connected to a sensor. As shown in FIG. 1 , the digital oximeter 101 and the sensor 102 need to connect the sensor 102 to a bloo...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above that although the above-mentioned oximeter can be used for measurement, its disadvantage is that for medical personnel, there will be a large number of cables in the consulting room, which increases the difficulty of work and some unpredictable risks

Although the portable oximeter can solve the problem of many cables in the monitor, causing inconvenience and inaccurate measurement, the portable oximeter cannot transmit the measured data to a dedicated data center for monitoring and analysis in real time.

[0006] In order to solve the problem of not being able to transmit data in real time, a Chinese invention patent application with application number 200380102580.5 and publication number CN 1708255A discloses a finger oximeter with remote communication capabilities. See the application file for details

Although the oximeter can transmit data wirelessly, the defect of the oximeter is that after the wireless communication function is added, the power consumption also increases accordingly; for the power management of the circuit, it is mainly operated by the observer at the remote monitoring device end , the observer activates the switch that sends the signal to activate / deactivate the finger oximeter, that is, artificially controls whether its power supply is activated or not, and at the same time, it controls the overall power supply or not

The disadvantage of this method is that if continuous monitoring is required, the power supply will always be on, and the power supply for the measurement circuit and RF circuit will always exist, as shown in Figure 1B

This will result in higher power consumption and shorter use time

The working time of the device can only be extended by shortening the single use time and turning off the device, which will cause inconvenience
