Precision and Reliability in Critical Medical Applications

Category: 

When it comes to critical applications, medical devices stand at the forefront, particularly those that are life-sustaining. In the world of medical technology, devices like artificial hearts and ventilators are essential in supporting or replacing vital physiological functions. For these machines to perform reliably, they rely on components that are not only exceptionally precise but also capable of enduring the rigorous demands of continuous operation. This is where Clippard valves come into play, offering robust and innovative solutions designed to meet the exacting standards of the medical field.

Artificial Heart Contraction Control

In artificial heart devices, precision is paramount. These life-sustaining machines rely on a delicate balance of timing and pressure to replicate the natural rhythm of a human heartbeat. Clippard valves are integrated into these systems to pilot diaphragm pumps, which operate by creating pulses that mimic the contraction and relaxation of a beating heart. Through finely tuned control of pressure and timing, Clippard valves enable artificial hearts to achieve the consistency and reliability essential for patient survival.

Ventilator Air Flow and Gas Blending

Clippard valves also play a crucial role in ventilator systems, another critical area within life-support technology. Ventilators depend on Clippard valves to pilot diaphragm pumps, which regulate the exact volume or pressure of air delivered to patients. In assist-control ventilator modes, the valve helps regulate a steady breath rate and volume, while in pressure-control modes, it maintains constant pressure to assist breathing.

In addition to this, Clippard valves are integral to gas blending within ventilators, combining oxygen and other gases to create a controlled mixture suitable for patients’ respiratory needs. This level of precise control, enabled by Clippard’s advanced valve technology, supports ventilators in providing safe and effective respiratory assistance.

Critical Medical Equipment - Ventilator Heart or Lung Patient in Hospital

What makes Clippard valves particularly suited for these high-stakes applications? It all boils down to a unique and time-tested technology known as the Clippard Spider.

Clippard Spider Technology

The Clippard Spider, invented and patented by Clippard in 1973, revolutionized valve technology. This deceptively simple design features a flat armature with a central plunger, resulting in a minimalist mechanism that significantly enhances reliability and performance. Here’s why this design has proven so effective in medical applications:

This technology has since been copied and mimicked by other manufacturers, but none have come close to perfecting it. Today, Clippard’s EV series—the original “spider” valve—remains the industry standard for long life and low leak. Building on this legacy, Clippard offers a wide range of valves that utilize this tried-and-true spider technology to meet the needs of many different industries and applications. All Clippard spider valves are extremely low leak. They provide exceptional reliability; long lifespans; and fast, precise control. They also consume very little power and have minimal internal volume.

Minimal Movement
  With movement as small as 0.007" (0.18 mm), Clippard's Spider
  Technology minimizes wear and tear, extending the valve's operational life.


Fast Response Time
  Clippard's Spider Technology design allows for rapid actuation,
  essential in applications where timing is critical.


Low Vibration and Noise
  Particularly in a hospital or critical environment, quiet operation
  is important for patient comfort and undisturbed operation.


Low Power Consumption
  Clippard's Spider Technology valves require minimal power, supporting the
  energy efficiency required in portable or battery-operated medical devices.


Reduced Internal Volume
  Less internal volume translates to a more compact design,
  ideal for integration into devices where space is at a premium.


Longevity
  Tested to withstand over 1 billion cycles, Clippard's Spider Technology
  valves offer unmatched durability.

 

These benefits make Clippard valves a trusted solution for manufacturers of medical devices and other critical applications. If you’re looking for expert assistance in designing or implementing precision pressure or flow control solutions, contact Clippard today.
