Background

Chad Therapeutics needed help turning a new type of non-electronic conserver valve that they had developed into a manufacturable design.  Speck Design worked with Chad and their consultant physician to develop the valve design and to design the packaging.  The end result was a small, packaged disposable oxygen conserver that was inexpensive to manufacture and fulfilled the target performance specifications.

Challenge

Maintain the following key features in the production design:

• Conservation without batteries or controls.
• Use with all oxygen sources, including the TOTAL O2 ® Delivery System and standard oxygen concentrators.
• Adequate saturations at higher flows when used in place of a nonrebreather mask.
• Proven efficacy while sleeping and during exercise.
• Built-in humidification effect – no need for supplemental humidification.
• Updated look with softer, small cannula tubing and no ear loops.
• Housing design that can be used with pursed-lip breathing for improved oxygen saturations and increased conservation.

Solution

In many ways, the OXYMIZER Disposable Oxygen-Conserving Devices function like standard conservers, because they extend oxygen duration by reducing the flow of oxygen from the tank when not required to saturate a patient.  However, they do not require electronics, batteries, switches, or flow controls. We designed a solution that utilizes a fluidic module to divert oxygen during exhalation into a reservoir contained within the conserver housing; this oxygen is then delivered to the patient upon inhalation.

Results

Speck Design developed a static fluidic valve that is inexpensive, disposable and meets all the performance criteria.
