Multifunctional oxygen output system based on respiratory rate and target blood oxygen value cooperative control

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...

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
