This is a device that is used to regulate the required positive or negative pressure in a system or equipment. It receives the input of the pressure sensor, provides control and sends an output signal for controlling the pressure. Because of this, they are used in a number of medical devices where they serve various purposes for the treatment of the patients.
Below we have listed some essential roles that proportional flow controls play in medical devices:
Reduce Pressure:
A pressure controller helps to reduce the incoming pressure of oxygen and other gases that are used in the treatment of the patient. The pressure of the oxygen coming out from the cylinder is very high and it can be dangerous for the patients. It’s necessary to manage this pressure and reduce it as per the need of the patient so that the patient can breathe easily and the waste of essential gases can be reduced.
In ventilators, a proportional valve controller is used to regulate the precise pressure of the oxygen and other gases to make breathing easy for the patients.
Maintain a Constant Pressure:
When the gas is directly coming from the source with high pressure then there are the chances of fluctuations that can damage the medical devices and can also create problems for the patients. For having constant pressure, a pressure controller is installed in the medical devices that do not let the pressure increase from the defined value. Constant pressure is necessary to maintain for having optimal performance from the medical devices that operate on air pressure and that supply gases to the patients. If the oxygen or other gas will not be delivered at a precise pressure then it will become difficult for the patient to breathe.
Provide Accuracy:
Dialysis machines serve as artificial kidneys. These machines use hemodialysis for cleaning the blood and maintaining a balance of the essential constituents. During this process, the blood of the patient is taken out of the body and is regulated through the machine with the help of a controller that controls the flow and the pressure. The blood is filtered inside the machine and has a balanced amount of all the constituents.
A high pressure controller is compulsorily used in dialysis machines to control the flow and the pressure of the blood while extracting the blood from the body and injecting it back after processing it into the body. It is necessary to maintain a required flow and accurate pressure so that the patient does not feel any kind of pain during the whole process and the dialysis process is also done precisely. That’s why, they are widely used in the medical devices where accuracy and reliability matter a lot.
Final Words:
As we know that medical devices are used for the treatment of patients. That’s why they need to work efficiently and accurately. For achieving this accuracy and providing accurate treatment pressure controllers are used commonly in medical devices. These controllers make it easy to have strong control over the pressure that is required to operate the equipment or to provide an accurate concentration of oxygen to the patients.
