Endo-Irrigator:
A multiple fluid dispensing device for dental surgeons that utilizes specially designed miniature check valves (designed by us), injection molded small connectors and on-off valves inside the dispenser handle was designed and transitioned to production. A critical aspect was the resistance to a variety of chemicals (including bleach) and avoiding contamination. See www.vista-dental.com under products, Endo-Irrigator. We have just completed a new product version that incorporates a vacuum line in addition to fluid delivery.
Bio-Chip Fluidic System:
A system for delivering fluids to a Bio-Chip was designed and built for Xeotron Corporation. This incorporated a disposable dock for the chip with three silicone rubber pinch valves, six "T" interconnects and a chemical reservoir with a living hinge cap. The complex part is being molded from a specially selected low/contamination polypropylene by an outside custom molder. Medical Murray is molding the interconnects and assembling product for this application. A photo of this device is shown.
Humidification device:
This product was designed for mass production in the USA and incorporates a special nozzle, easily operated three way valve and connectors which must not leak under low or high internal pressure. The product was strength and cost critical and can be seen at www.mrmisty.com.
Syringe injection internal valves:
Pressure relief valves have been designed and integrated into high pressure syringes for the delivery of high viscosity embolism agents. These valves were custom designed, prototyped, tested and released for injection molding in volume by our customer.
Interconnection valves:
Connect/disconnect devices were designed for the cleaning fluid system for a dialysis machine. These were zero leakage volume devices (during connecting and disconnect) and incorporated a magnetic sensor to verify correct insertion. A schematic section view is shown.
Safety Syringe:
This product was designed in conjunction with our customer and required three precision injection molded parts from polypropylene. A spring and safety clip (from stainless steel) was also incorporated into the product. Assembly included an ultrasonic weld to the needle cannula. A prototype mold and assembly equipment were purchased and a volume of assemblies produced for field testing and demonstration. A photo of the assembly with the cover is shown below:
