Valves for air and oxygen in medical technology

You develop medical devices.

Festo supports you all the way from designing to developing and producing suitable subsystems.

Along with solenoid valves, proportional valves with piezo technology are suitable for use in medical technology. They are:

  • Silent: ideal for mobile applications and those close to patients
  • Oxygen-compatible, for applications such as respirators

Smaller, lighter and quieter: piezo valves in medical technology

Piezo valves are amazingly well suited to valve functions in the field of medicine.

  • Silent
  • No heat build-up
  • Low energy consumption
  • Lightweight
  • Proportional characteristics
  • Very short switching times
  • Compatible with oxygen
  • Sturdy and durable

Treatment systems

Oxygen therapy for mobile applications

In action:

Small and lightweight piezo valves regulate the gas flows and pressures that release oxygen in infinitely variable steps.

Stationary ventilation in a clinical environment

Precise regulation and control of fluid flows from the blood and dialysate stream are crucial when it comes to efficient dialysis.

In action:

Piezo valves, media valves, pneumatic valves, proportional pressure regulators

Surgical tools

An example from eye surgery shows pneumatically operated surgical tools being controlled.

In action:

Pneumatic control unit comprising solenoid valves and piezo valves for the following functions:

  • Actuating surgical tools
  • Vacuum-supported extraction
  • Conveying fluids

Regulation of fluid flows, gas flows and slime at dental service units

The various instruments are controlled independently of one another by switching valves, proportional valves, pumps and compressors.

Medical equipment

Training torsos in medical training simulate breathing, pulse and bodily fluids, such as tears.

Intelligent control systems are used for simulating air and fluid movements.

Regulation of gas flows and pressures in medical mattresses for nursing beds.

Piezo valves actuate the chambers individually – quietly and with a soft-start function.
