Abstract: A holder for an elongated medical body suitable for insertion into a patient during a surgical procedure is provided. The holder includes a first outer member having a first inner surface, and a first outer surface, and a second outer member having a second inner surface and a second outer surface. The holder also includes a core extending between the first and second outer members, and at least one holding member placed between the inner surfaces of the first and second outer members. The holding member or holding members are compressible for holding the elongated medical body in the holder.

Abstract: A pump interface tubing for use in a peristaltic pump includes a tubular core having an outer surface and a treatment on the outer surface. The treatment reduces static charge buildup on the tubular core during operation of the peristaltic pump, and thereby reduces the noise signal that might otherwise undesirably couple to a signal of interest. Treatments include nitrile layers, heat shrink layers, cotton fiber layers, and anti-static sprays.

Abstract: A sensor used to control a peristaltic pump includes a housing, a tubing channel extending through the housing, a pressure sensor adjacent the tubing channel to measure an internal pressure of a tubing set inserted into the tubing channel, and a temperature sensor adjacent the tubing channel to measure a temperature of a wall of the tubing set. The sensor can also include a bubble sensor adjacent the tubing channel to detect bubbles within a fluid flowing through the tubing set. The sensor can be used to control a peristaltic pump. For instance, the peristaltic pump can include a microprocessor that can determine the internal pressure of the tubing set from an output of the pressure sensor and compute therefrom a pump factor required to maintain a given flow rate of the fluid flowing through the tubing set. It can then adjust a pump factor of the pump head to the computed pump factor.
