Abstract: A tubing assembly having a signal generator placement control device for use in conjunction with electronic catheter guidance systems. The control device facilitates control of the position the guidance systems' signal generator relative to the end of the tubing assembly. The tubing assembly includes a tubular insulator coupled to one end of the control device, and the tubing assembly includes a tubular connector attached to the other end of control device. Also, the tubing assembly includes a catheter attached to the tubular connector and an end member attached to the catheter.

Abstract: An enteral fluid infusion system wherein fluid is pumped through a conduit from a fluid supply source to a patient by a rotary peristaltic pump operating in an intermittent duty cycle mode which includes a free flow detector. The free flow detector includes a sensor for the operation of the peristaltic pump, as for example by the rotation of the rotor and/or motor; a sensor for the flow of fluid in the conduit. The free flow detector compares the sensed operation of the pump with the sensed flow against predetermined criteria. During operation of the fluid infusion system, if flow is sensed when the pump is not operating, as determined by the fact that no rotation is occurring, an alarm will be initiated to indicate that a free flow condition exists.

Abstract: The invention is an improvement on rotors in peristaltic pumps for advancing enteral feeding solutions through medical tubing. The improvement comprises the provision of a plurality of removable, one-piece rollers disposed between the front and rear plates of a rotor. Each of the rollers is contained between a pair of vertically aligned, open channels provided in the front and rear plates. To permit free rotation of each roller within its respective pair of channels, an inner portion of each channel has dimensions slightly larger than the outer ends of each roller. To ensure that the rollers are, during normal use, retained within their respective channels, an outer portion of each channel has dimensions slightly smaller than the dimensions of the end of each roller. Each roller may be inserted or removed into its respective pair of channels by force-fitting the ends of that roller through the outer portion of each channel.
