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 oxygen output according to the changes in the patient's physiological parameters
In 2008, the British Thoracic Society (BTS) issued a complete and authoritative guideline for oxygen therapy, which for the first time listed blood oxygen saturation as the fifth vital sign besides human heartbeat, respiration, blood pressure and pulse. Oxygen therapy must have a clear target blood oxygen saturation (that is, a clear treatment goal). During the oxygen supply process, the patient's blood oxygen saturation must be dynamically monitored and maintained. It can be seen that the existing oxygen therapy equipment can no longer meet the needs of modern medicine. needs

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 coordinated control of the respiratory rate and the target blood oxygen value. The multifunctional oxygen output system is mainlycomposed of a control module, a multi-parameter monitoring module, an electronic flow valve, an air channel change-over switch, a human-computer interaction interface, a communication module and embedded software. The multifunctional oxygen output system has the beneficial effects that a plurality of types of treatment modes in the process of oxygen treatment and nebulization treatment in medicalunits are provided to meet different clinical needs; a great social significance that about 50% of oxygen or medicine resources are saved when a respiratory frequency-synchronized treatment mode is used is achieved; and meanwhile, a number of physiological parameters are monitored in real time during the oxygen treatment or nebulization treatment, and the effectiveness and safety of the treatmentare ensured.

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...
