Elastomeric Pumps. Also known as "homeballs," "ball pumps,"or "grenade pumps.". An elastomeric pump is a device that infuses medication once the tubing is unclamped. Built with an elastic balloon inside a very tough outer cover, the device pushes intravenous medication through tubing and a filter that is attached to the reservoir.

Elastomeric pumps are available with different flow rates for very slow or faster drug delivery. According to ISO standard 28620, an average flow rate deviation of +/-15% is tolerated for mechanical pumps with a fixed flow rate. As the standard only considers the average flow rate, higher deviations may be possible during infusion.

A sheet of VHB-4910 tape is rolled into the pump module with the seam self-bonded. The initial length, radius, and thickness of the pump module are L 0 = 40 mm, R 0 = 20 mm, and H 0 = 1 mm. The pump module experiences a prestretch of λ pre = 2 and is enforced at two ends by two rigid tubes. The working length l is defined as the length of …

Most elastomers in PC pumps can be classified as conventional nitrile (NBR). The base polymers for these elastomers are manufactured by emulsion copolymerization of butadiene with acrylonitrile (ACN). ACN contents in nitrile elastomers typically vary from 30 to 50%, with the cost of the elastomer increasing marginally with …
