Embodiment 1

[0018] Such as figure 1 As shown, the present invention includes a microprocessor, a D / A converter, an A / D converter, an RF transceiver, an LED drive circuit and a photoelectric sensor, and the microprocessor is simultaneously connected with the D / A converter, the A / D converter The RF transceiver is also connected to the RF antenna; the D / A converter is also connected to the LED drive circuit, photoelectric sensor, amplifier, filter, signal conditioning circuit, voltage-current conversion circuit and integration circuit in turn, The integrating circuit is also connected to the A / D converter.

[0019] When in use, the microprocessor generates driving signals of red light with a wavelength of 660nm and infrared light with a wavelength of 940nm in time division, and the signals are transmitted to the LED drive circuit after D / A conversion. The LED drive circuit amplifies the power of this signal, and then sends it to the red light and infrared light emitting diodes placed side b...

Embodiment 2

[0021] This embodiment is preferably as follows on the basis of Embodiment 1: the microprocessor is also connected to a data memory. It can store the measured blood oxygen saturation information and the information transmitted through the RF antenna to avoid the loss of information.

[0022] The model of the RF transceiver is AD9361. This type of RF transceiver has a long transmission distance and fast transmission and reception speed, which is very suitable for use in the monitoring field.

[0023] The photoelectric sensor is a finger sleeve photoelectric sensor. The photoelectric sensor is conveniently placed on the human body and is not easy to slip off, further ensuring the accuracy of measurement.

Abstract

The invention discloses an oxyhemoglobin saturation detection terminal bringing convenience to monitoring. The oxyhemoglobin saturation detection terminal comprises a microprocessor, a D / A converter, an A / D converter, an R / F transceiver, an LED driving circuit and a photoelectric sensor. The microprocessor is connected with the D / A converter, the A / D converter and the R / F transceiver at the same time. An RF antenna is further connected to the RF transceiver. The D / A converter is further connected with the LED driving circuit, the photoelectric sensor, an amplifier, a filter, a signal conditioning circuit, a voltage-current conversion circuit and an integral circuit in sequence. The integral circuit is further connected with the A / D converter. By means of the principle, the oxyhemoglobin saturation detection terminal is not prone to being disturbed by other signals, the measured result can be transmitted through the RF antenna, manual record reading is avoided, the result collecting efficiency is improved, and convenience is brought to later-period monitoring.

Description

technical field [0001] The invention relates to the field of intensive care, in particular to a blood oxygen saturation detection terminal which is convenient for monitoring. Background technique [0002] Since the advent of single-function monitoring equipment in the 1970s, it has gradually been widely used in clinical monitoring. However, due to the limitations of its monitoring function, single-function monitoring equipment is far from meeting the needs of clinical applications, which seriously restricts the hospital's rescue of critically ill patients. In the 1990s, with the development of sensing technology and electronic technology, monitoring parameters increased continuously, from single parameter monitoring in the past to multi-parameter monitoring. For example, from a single ECG monitoring, blood pressure monitoring, and blood oxygen saturation monitoring, it has gradually developed into a monitoring system that includes ECG, respiration, blood pressure, blood oxy...
