Breathing support equipment airway and safety control system and control method

Abstract

The invention provides a breathing support equipment airway and a safety control system and a control method. The breathing support equipment airway comprises: a main air inlet passage, a reserve airinlet passage and a breathing mask, wherein the main air inlet passage is connected with the reserve air inlet passage in parallel and is respectively connected with the breathing mask; a front end ofan air outlet of the main air inlet passage is provided with an air outlet pressure sensor; the breathing mask comprises a mask body, the mask body is provided with a pressure collecting port, and the pressure collecting port is provided with a mask pressure sensor. The control method of the breathing support equipment safety control system is also provided. A processor module, a turbine module,a pressure sensor and a power module of the breathing support equipment safety control system are respectively provided with a backup module, so that the processor module, the turbine module, the pressure sensor and the power module not only can work jointly, but also can work independently to complete an air supply function. When one of the modules fails, the other module can replace the work ofthe current module, maintain an output pressure of the breathing support equipment, maintain a user's normal breathing, and ensure the user's life safety.

Description

technical field [0001] The invention relates to the technical field of medical equipment manufacturing, in particular to a respiratory support equipment airway and safety control system and control method. Background technique [0002] In the field of medical respiratory support equipment (such as ventilator, high-flow respiratory humidification therapy instrument), respiratory support equipment, as one of the life support equipment, should have stable working performance, even if one of the functional modules fails, it should be able to degrade When using it, the phenomenon of stopping the gas supply cannot occur, ensuring the safety of personnel. [0003] The working principle of the respiratory support equipment with turbine air supply is: the processor of the respiratory support equipment controls the turbine speed to reach the pressure set by the user by collecting the pressure at the patient end. Existing medical respiratory support equipment is composed of various fu...

AI Technical Summary

Problems solved by technology

Since the consistency of the electronic components themselves cannot be guaranteed to be 100%, aging cannot fully detect all problems within a short period of time, and with the use of respiratory support equipment, aging of electronic components is more likely to cause damage to individual components, resulting in respiratory support equipment not working properly

Respiratory support equipment products contain a large number of electronic components, so failure of individual components cannot be guaranteed

In reality, there are many cases where respiratory support equipment stops working due to the failure of individual components, resulting in life-threatening

[0004] Traditionally, a pneumatic respirator with a safety monitoring function based on the Internet of Things (CN201510847047) discloses a pneumatic respirator, including a central control device, a respiratory support device electrically connected to the central control device, and a monitoring and alarm mechanism. The respiratory support equipment structure includes an inspiratory air source device, a humidifier, an oxygen partial pressure device, a breathing control device, a spirometry device and a breathing mouth, the inspiratory air source device communicates with the humidifier, and the oxygen partial pressure device communicates with the humidifier. Through the wireless communication module, the pneumatic respirator with safety monitoring function based on the Internet of Things can realize the real-time monitoring of the use of the respirator by the staff; through the monitoring and alarm module, the oxygen source pressure alarm device and power failure Turn on the alarm device, switch fault alarm device, temperature detection device, level sensor and airway pressure measurement device to monitor the working state of the respirator in real time, and timely alarm, which improves the reliability of the respirator, but this invention is only for respiratory support equipment Real-time monitoring of each module of the system, and then an alarm, which plays a certain role in warning, but the processing time of the fault will still bring unpredictable risks to the patient
