Multi-Layered Silicone Pump Segment to Address Bulging

摘要

A fluid infusion system that is configured to infuse fluid from a source to a patient. The fluid flows through tubing formed of one or more tube segments that define a fluid lumen. At least a portion of the tubing has a multi-layered configuration including an outer layer and an inner layer. The outer layer has one or more characteristics that are particularly suited for an outer layer such as to resist the environmental conditions that the tubing may experience. The inner layer is formed of a material that is compliant and resilient such that the inner layer may adapt to variations in fluid pressure during pumping of fluid through the tubing

主权项

1. A medicant infusion pump system, comprising:
a tubing having an outermost layer formed of a cut-resistant material and an innermost layer formed of a material that is more resilient than the outermost layer; a pump mechanism mechanically coupled to the tubing and configured to act on at least a portion of the tubing to cause fluid flow through the tubing.
