Combined medical instrument base and probe cover dispenser

A sensor system has a two-housing arrangement, each housing of which contains a transducer. One housing includes the transmitter transducer and a flat engaging surface for pressing against the fluid line and deforming it. The other housing includes the receiver transducer mounted so that it is coupled to the bottom of a rectangular U-shaped channel for receiving the fluid line. A spring biases the flat surface of the first housing into contact with the fluid line and deforms the fluid line into the shape of the channel so that the fluid line fills the channel. The channel is shaped to force the fluid line into a general rectangular shape as it is pressed into the channel by the flat surface. Two walls of the deformed fluid line are oriented in a direction perpendicular to the flat engaging surface of the first housing and provide an opposing force to the flat surface. The fluid line stiffness and pressure of the fluid within act as an opposing spring to limit the travel of the transmitter transducer housing to result in firm and continuous contact between the transducers and the fluid line. A stop mechanism prevents the two housings from contacting.

Medical tube clamp

A storage chamber large enough to store a predetermined number of probe covers is formed into a dispenser body. A spring biases the probe covers toward one end of the chamber at which is located a slide. The slide has an indentation used to retrieve a single probe cover from the chamber at a time when aligned with the chamber. Located in the indentation is an aperture tube for receiving a probe of the instrument to be covered. The probe is pressed into the probe cover and into the aperture thus causing the probe cover to stretch and cover the probe. A flange formed on the slide is pressed by a user to align the indentation of the slide with the chamber. The slide is spring loaded so that releasing the flange will result in the slide moving such that the identation is located outside the chamber and the retrieved probe cover can be applied to the instrument. A door in the dispenser is raised to allow access to the chamber for the insertion of a stack of probe covers. Probe covers in each stack are held together with a removable band. After inserting a stack of probe covers in the chamber, the door is closed and a pull tab on the band pulled to remove the entire band from the stack. A quantity indicator is provided which allows the user to see the quantity of probe covers remaining in the chamber without opening the door.

Probe cover dispenser

The clamp for flexible tubing may be used in conjunction with an infusion pump instrument or separately. The clamp includes a pair of elongated clamping members pivotally hinged together and biased to clamp a segment of flexible tubing received between the clamping members. A latch is also preferably provided for allowing the clamping members to be releasably latched apart. The latch, and the elongated clamping members are arranged in a manner such that when the clamp has a segment of flexible tubing received between the clamping members and the clamp and tubing are set between the housing and door of an infusion pump, closing the door causes the clamp to release to an open position allowing fluid flow, and opening the door causes the clamp to automatically move to a closed position, clamping the tubing so as to prevent fluid flow.
