Problems solved by technology

[0005] Therefore, the existing oxygen therapy program can no longer meet the requirements of precision medicine. A medical instrument that can monitor the patient's arterial oxygen saturation in real time and dynamically control the oxygen flow based on this is proposed in clinical and personal health. It is very necessary in management. For this reason, the present invention proposes a technical scheme of an intelligent servo oxygen therapy control system, which has a high degree of intelligence, stable technology, and a cost equivalent to that of existing ordinary oxygen inhalers, which is conducive to clinical popularization and promotion. use

Embodiment 1

[0032] Embodiment 1: the product preparation example of band humidification device of the present invention

[0033] The main structure of the product is as image 3 As shown, the specific parameters of the main components are:

[0034] 1. Oxygen measurement device (1): finger clip-on oximeter, adult specification, using TI's MSP430FG4619 single-chip microcomputer as the processing core; blood oxygen saturation probe adopts two-color light-emitting diode PDFE833, and the emission wavelengths are 660nm and 940nm respectively ; The power module adopts TPS62007DGS chip, the output voltage is 3.3V.

[0035] The DAC12 inside the microcontroller periodically outputs two 100Hz pulses with a duty ratio of 1:4, which are driven by a current-amplified drive circuit to alternately light up the red and infrared LEDs in the blood oxygen probe. The photoelectric receiver in the probe sends the received signal to the OA amplifier inside the microcontroller for amplification, and the amplif...

Embodiment 2

[0047] Embodiment 2: the clinical application example of the present invention

[0048] The product prepared according to Example 1 is used for the application of oxygen therapy for patients in the Department of Respiratory Medicine, and the operation method is as follows:

[0049] 1. Clip the finger-clip oximeter prepared in Example 1 on the right middle finger of the patient, turn on the oximeter, and the oximeter enters the monitoring program;

[0050] 2. Insert the oxygen input port (6) into the wall oxygen supply port, and check the airtightness and firmness of the connection;

[0051] 3. Open the "open" control button (8) provided on the control unit (3), and open the control unit (3);

[0052] 4. The oximeter starts to transmit monitoring data via bluetooth, and the information reminder module (5) on the control unit (3) displays real-time monitoring parameters, including pulse rate, blood oxygen saturation (SpO 2 ), perfusion index (PI);

[0053] 5. The information ...

Abstract

The invention relates to an intelligent servo oxygen therapy control system, which is mainly formed by a blood oxygen measuring device (1), a communication module (2), a control unit (3), an electronic flow valve (4), an information reminding module (5), an oxygen input port (6), and an oxygen output port (7). The anoxia degree of a patient is judged by adopting an oxygen saturation value obtained in real time, and an oxygen therapy scheme is given by a built-in oxygen therapy data model, so the medical treatment of an oxygen uptake link is more precise and scientific; the dynamic oxygen saturation value is adopted, change of the anoxia degree of the patient is judged in a tracing manner, and an oxygen therapy flow value is automatically corrected by the control unit, so not only is the clinical effect of the oxygen therapy ensured, but also unnecessary consumption of oxygen is reduced and a large quantity of cost is saved for medical units.

Description

Technical field [0001] The invention relates to an intelligent servo oxygen therapy control system, which belongs to a medical device for measuring blood oxygen saturation of a patient and dynamically controlling the oxygen flow rate during oxygen inhalation therapy. Background technique [0002] Hypoxia is the root cause of many diseases, and it directly threatens people's lives when it is serious. Many diseases will cause the lack of oxygen supply. Oxygen inhalation is one of the most commonly used rescue or treatment methods in hospitals. By giving oxygen, the partial pressure of oxygen in arterial blood (PaO 2 ) and arterial oxygen saturation (SaO 2 ), increasing arterial blood oxygen content (CaO 2 ) is a treatment method to correct the oxygenation state caused by various reasons, promote the metabolism of the tissue, and maintain the life activities of the body. During oxygen inhalation therapy (hereinafter referred to as "oxygen therapy"), medical staff give differ...
