Printed circuit boards play a vital role in medical ventilators, critical devices that help patients with respiratory failure breathe. PCB needs to ensure 100% reliability and safety in medical ventilators. The main functions of PCB in ventilator are:
Control Circuit: The PCB is used to control the flow of electrical signals within the ventilator, controlling the operation of motors, valves, and other components that regulate the flow of air into and out of the patient's lungs.
Monitoring Circuit: Used to monitor the operation of the ventilator and the patient's vital signs. This includes monitoring the flow and pressure of the air delivered to the patient, as well as monitoring the patient's heart rate, blood oxygen levels and other key parameters.
Display Circuit: The PCB is used to display the patient's vital signs and other information such as the air pressure and flow delivered to the patient. This information is critical for healthcare providers to monitor patient conditions and adjust ventilator settings as needed.
User Interface Circuit: The PCB is used to control the ventilator's user interface, allowing healthcare providers to adjust the device's settings and monitor the patient's condition.
