A peristaltic pump head includes a housing assembly adapted for mounting to a drive mechanism, a roller assembly arranged with the housing assembly and a flexible conduit extending through the housing assembly and engageable by the roller assembly to impel fluid therethrough. The roller assembly and the flexible conduit are removable from the housing assembly without disconnecting the entire housing assembly from the drive mechanism. The roller assembly can include an axially extending drive shaft, a roller control body fixedly mounted to the drive shaft, at least a first end plate rotatably mounted about the drive shaft, and at least a first roller arm pivotably mounted to the first end plate. The flexible conduit can include a length of hollow tubing made of an elastomeric material, and at least one overmolded end fitting made of a rigid polymeric material and fused to an end of the hollow tubing.

A valve for a tubing kit used provides a resilient element naturally moving to a closed state to reduce opportunity for inadvertent leakage of medicine and to reduce effort required by healthcare personnel to seal the fluid line. In one embodiment the resilient element is a spring serving to compress the walls of IV tube in the closure and in a second embodiment the resilient element is an elastomeric member that is deformed to provide an opening to allow passage of fluid through the fluid line.

A method and system is disclosed for operating a medical device with or without a cassette in place. A method is disclosed for adding additional VTBI to an ongoing infusion without stopping the infusion and with maintaining the infusion parameters. A method and system is disclosed for changing the CCA without having to interrupt or completely stop an ongoing infusion. Quick titration buttons are provided to allow improved navigation between various delivery display screens.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

A cassette with free flow prevention for use with an ambulatory pump. The cassette includes a free flow prevention clamp and a housing. The free flow prevention clamp includes a clamping section having a first side and a second side, a first elongate section extending from the first side, and a second elongate section extending from the second side. The housing supports the free flow prevention clamp and defines a channel for receiving a tube. The elongate sections extend parallel to the channel and the clamping section extends across the channel. The free flow prevention clamp is configurable within the housing in an open condition that allows fluid flow through the tube when force is applied to one of the elongate sections and in a closed condition that prevents fluid flow through the tube when the force is removed from the elongate sections.

An injection system is proposed which comprises at least one supply station for supplying a medical fluid to be injected into a patient's vasculature, a pressurizing unit comprising a motor for pressurizing said medical fluid, a delivery arrangement in fluid communication with the at least one supply station and a patient set assembly in fluid communication with the delivery arrangement. The patient set assembly comprises a delivery tube for delivering the pressurized fluid to the patient and a peristaltic pump component comprising a casing which includes an inlet port and an exit port, the inlet port being in fluid communication with the delivery arrangement and the exit port being in fluid communication with the delivery tube. According to an embodiment of the present invention, in proximity of the inlet port, the casing of the peristaltic pump component has a substantially U-shaped configuration. The present invention also relates to a patient set assembly and to a peristaltic pump component.

Fluid supply systems and methods for therapeutic fluid delivery systems, including those used for negative pressure wound therapy (NPWT) systems and methods.

In some embodiments, apparatuses and methods are provided herein useful to provide fluid nutrition and hydration. In one illustrative example, a feeding set for use with a peristaltic enteral feeding pump has sections of flexible tubing or conduit, a dispensing control valve that is in fluid communication with the tubing, and a retention disk. In some configurations, the feeding set has as attachment mechanism, which may be formed by one clips or hooks extending from the dispensing control valve and coupling geometry of the retention disk. By some approaches, the clips or hooks and the coupling geometry are configured to attach the feeding set with the pump, such as by attaching the feeding set to an internal panel of the feeding pump. In operation, the feeding set and pump are used to move fluid nutrition and hydration from a container or bag to the patient in a controlled manner.

The present invention relates to a sensing device, a method of use of a sensing device and a method of manufacture of a sensing device. Embodiments are generally configured as sensor arrays for detecting a pressure change within an infusion line to pre-empt or detect line occlusions in the administration of medical infusions. Generally, embodiments comprise a support component having a support surface for mounting thereon one or more electrically connected switches, a length of expandable tubing for passing a fluid therethrough and are secured to the support surface and in physical contact with the electrically connected switches. The one or more electrically connected switches forms a sensor array adapted to sense expansion of the expandable tubing indicative of pressure changes resulting from line occlusions.

A fluid injection device having a body for coming into contact with an injection site (SI); at least two fluid reservoirs (210); and an injection needle (120) for penetrating into the injection site (SI) so as to inject therein the contents of one or more reservoir(s) (210); the device further has a single rotary actuator (130) that, when it turns in a first direction of rotation, activates the selection of the reservoir(s) (210) to be dispensed, and that, when it turns in the opposite direction, actuates a dispenser system, in particular a peristaltic pump (150).
