Our customer manufactured a variety of respiratory equipment and ventilation devices. Humphrey’s proportional valve technology enabled the company to recover from a more than 50% production failure rate and enhance their competitive advantage in adult, pediatric and neonatal medical ventilators. Learn how.
When a customer needed a three-valve manifold assembly with extremely tight space requirements, we modified two HK5 valves to get the job done. With the custom valve manifold, the customer was able to exchange a relatively heavy oxygen tank with a limited supply for a lightweight, portable oxygen concentrator. Read our case study.
When a respiratory equipment manufacturer needed a 2-way pilot-operated valve assembly that could handle high-flow air and oxygen, Humphrey got to work. Our custom manifold eliminated the need for hospitals to purchase two separate ventilators. Learn how we combined a standard valve model with a poppet solenoid valve and mounting adapter to get the customer what they needed.
A manufacturer of respiratory and critical care products wanted to introduce a portable rebreather for emergency medical treatment of victims of toxic gas or smoke inhalation. Humphrey designed a valve assembly that met the critical response time and desired size requirements for portability. Discover how our pilot-operated 310 valve addressed the hysteresis challenge with precise gas metering.
A compression therapy device designer needed a valve for a product that prevented fluid from pooling in the legs of immobilized patients. Humphrey answered with a manifold with three integrated solenoid valves, which eliminated multiple connection points to reduce the possibility of leakage. The manifold simplified the customer’s installation since it was custom-built for their unit. Learn more.
A ventilator manufacturer needed a preassembled system that met tight dimensional requirements and critical performance specifications, and was compatible with the company's existing controller. Humphrey met those specifications and helped the customer save on assembly costs. Learn how.
A critical medical device manufacturer needed a valve manifold system that was reliable and could handle a 30 million cycle MTBF rate. Humphrey designed a complete assembly that fit within the existing equipment and greatly improved device performance reliability. We also accelerated the development process, delivering functioning products in an exceptionally short period of time. Read on to learn how we did it.
We partnered with a manufacturer that created special mattress systems for pressure management and patient repositioning to help prevent the formation of pressure ulcers. The customer was concerned about leak rates in the system. Humphrey designed a custom valve that not only reduced leak rates but also made installation easier, thus lowering assembly costs. Read on to learn more.
A manufacturer of O2 concentrators for in-home oxygen therapy wanted a valve design that would increase flow rate. Humphrey designed a low-pressure pilot valve that increased the flow rate by 20% without taking up additional space in the system. Read on to discover how we did it.
Humphrey developed a special hand pump for a client who designed and manufactured coronary care equipment. Our product allows a heart assist device to be moved while untethered from the drive console. Read the complete case study.
Modern anesthesia equipment consists of complex pneumatic circuits used to supply various gases, including oxygen. A manufacturer of anesthesia equipment wanted to enhance the reliability of its gas delivery valves. Humphrey worked closely with the company to develop the valve assembly and the quality control methodology. Learn how.
A physical therapy equipment manufacturer wanted a valve assembly with zero leakage and diverse functionality for many types of equipment. Humphrey created a design that not only eliminated leakage but also provided a smaller package that resulted in more professional-looking equipment. The customer now has one standard manifold that can be used on each piece of equipment. Read more.
A biomedical manufacturer wanted to adapt aerospace oxygen concentrator technology for use in home therapy. Humphrey created a special diaphragm valve that delivered high flow, precise control and reliability. Discover how we implemented deeper seats to increase flow for higher efficiency while maintaining zero leakage.
