Problems solved by technology

During oxygen therapy and nebulization therapy, the two devices are used alternately, which not only increases the workload of medical staff, but also increases the cost of the hospital to purchase and maintain the two devices
[0003] Moreover, the existing oxygen therapy equipment and oxygen jet nebulization equipment have a single means of controlling the oxygen output, and the medical staff realizes the oxygen output control after setting the output flow value, and there is a lack of dynamic monitoring of the patient's blood oxygen saturation, respiratory rate and other physiological parameters. monitoring, and it is impossible to dynamically adjust the

Embodiment 1

[0038] Embodiment 1: preparation of the present invention

[0039] List of major components used in the present invention:

[0040] The control module adopts ARM microcontroller (MCU), model STM32F415RGT6, STMicroelectronics.

[0041] The multi-parameter monitoring module is composed of five modules: blood oxygen monitoring module, respiratory rate monitoring module, body temperature monitoring module, heart rate monitoring module, and blood pressure monitoring module. 940nm, finger clip type, the blood oxygen saturation monitoring range is 70% to 100% (no definition below 70%), and the measurement error is not greater than 3%. 0.01kPa, monitor the patient's mouth and nose peripheral pressure changes to obtain respiratory rate; the body temperature monitoring module uses a patch-type thermistor as the detection part, the range is 25°C to 45°C, the measurement accuracy is 0.1°C, and the measurement error is 0.2°C; the heart rate electrode range is 25cpm~ 250cpm, measurement a...

Embodiment 2

[0048] Embodiment 2: the clinical application example of the present invention

[0049] 1. Apply the present invention for oxygen therapy and insert atomization therapy during the treatment process. The treatment objects are patients diagnosed with carbon dioxide retention, cough and phlegm, and select the target blood oxygen servo + breathing synchronization mode.

[0050] Doctor's prescription: For patients with carbon dioxide retention, the target blood oxygen range is 88% to 92%, the oxygen inhalation time is 20 hours, and the oxygen flow rate is 2L / min. After 5 hours of oxygen inhalation, nebulization treatment was performed, and the nebulization liquid configuration: 0.2 g of ambroxol was dissolved in 5 ml of gentamicin.

[0051] According to the target blood oxygen range given by the doctor's prescription, the target blood oxygen value is 88% to 92%, and the medical staff set the target blood oxygen value to 90% on the man-machine interface, set the oxygen inhalation ti...

Abstract

The invention provides a multifunctional oxygen output system based on respiratory rate and target blood oxygen value cooperative control. The multifunctional oxygen output system is mainly composed of a control module, a multi-parameter monitoring module, an electronic flow valve, a gas path diverter switch, a human-computer interaction interface, a communication module and embedded software. Theinvention has the beneficial effects that a plurality of treatment modes are provided in the oxygen treatment and atomization treatment process of a medical unit, and different clinical requirementsare met. About 50% of oxygen or medicine resources are saved when a respiratory rate synchronous treatment mode is adopted, and good social significance is achieved. Meanwhile, multiple physiologicalparameters are monitored in real time in the oxygen treatment or atomization treatment process, and effectiveness and safety of treatment are guaranteed.

Description

technical field [0001] The invention relates to a multi-functional oxygen output system controlled cooperatively based on respiratory frequency and target blood oxygen value, which belongs to clinically used medical equipment. Background technique [0002] Medical oxygen output control equipment is a necessary medical device for medical institutions to perform oxygen therapy. At present, oxygen inhalers are commonly used in medical institutions for oxygen therapy. At the same time, many patients with respiratory diseases need atomized inhalation therapy during oxygen therapy, and medical staff need to use additional atomizing equipment (commonly used is oxygen jet atomizing atomizing equipment). During oxygen therapy and nebulization therapy, the two devices are used alternately, which not only increases the workload of the medical staff, but also increases the cost of purchasing and maintaining the two devices for the hospital. [0003] Moreover, the existing oxygen therap...
