Abstract:
An embodiment is directed to pressure plate for attachment to an infusion pump, where the pressure plate includes a tubing support surface at least partially surrounded by a raised perimeter support. The pressure plate includes a plurality of guide structures extending from the raised perimeter support that define a passageway for an infusion pump tube. Additionally an attachable flow stop assembly is included that includes an attachable occlusion arch and an attachable flow stop arm. The attachable occlusion arch includes a plurality of tab structures that couple to the raised perimeter support. The occlusion arch further includes an aperture configured to surround an infusion pump tube threaded therethrough. The attachable flow stop arm is operatively coupled to the raised perimeter support adjacent the attachable occlusion arch in a spring-biased fashion such that the aperture in the occlusion arch may be selectively occluded by the flow stop arm.
Abstract:
An overload protection method and apparatus for a medicament syringe pump force sensor. A dome switch is employed with force sensor components of a medicament pump. The dome switch collapses at overload pressures, isolating the force sensor from pump driving forces that exceed the force sensor limit. An alarm signal can be triggered by the overload, and initiate pump shut down.
Abstract:
A drug or fluid delivery device includes a pump having a control module. A cassette is removably mounted to the control module. A reservoir is contained within the cassette, and contains a fluid to be delivered to a patient. A protrusion extends from an interior surface of the cassette, creating and maintaining a crease in the reservoir as the fluid is emptied therefrom, thereby creating a fluid path along which the fluid travels to reduce occurrences of the reservoir deleteriously sealing off pockets of fluid as the reservoir is emptied.
Abstract:
A dose request device for a medicament delivery device can include a housing, a dose request button, a short-range non-contact identifier, a communication interface configured to communicate with the medicament delivery device, and a controller. The short-range non-contact identifier can be configured to be capable of reading an identification code from a tag when the tag is disposed within a first range and not to be able to read the identification code from the tag when the tag is disposed beyond a second range. The controller can be configured and programmed to determine whether the identification code read by the short-range non-contact identifier matches any authorized identification code of a set of one or more authorized identification codes, and if so, and if the dose request button is pressed, the controller can then communicate a dose request to the medicament delivery device via the communication interface.
Abstract:
A safety catheter includes a catheter hub, a needle cannula having a tip, and a tip protector. The tip protector includes an outer member and an inner member therein. The outer member has a projection releasably engaging the catheter hub. The inner member has a pair of arms extending to free ends from a base. The inner member is axially shiftable relative to the outer member between a first position wherein the needle tip is distal of the tip protector and the free ends of the arms are spread apart such that the distal tip is not shielded, and a second position wherein the tip is within the inner and outer members and the free ends of the arms are brought into close proximity such that the distal tip is shielded. The inner member is entirely received within the outer member in both the fort and the second positions thereof.
Abstract:
An embodiment of a medication dispenser comprises a drug pump having a control module. A medication dose request device can be in communication with the drug pump. A dispensing device, for dispensing substantially solid medication in response to activation of the medication dose request device, can be in communication with the drug pump.
Abstract:
An apparatus, method and program product detects an occlusion in a fluid line by determining if a relationship between force measurements departs from an expected relationship.
Abstract:
Embodiments of a tamper-proof adapter can be configured to provide interconnection of medical tubing or other devices with varying fitting or coupling types. In one embodiment, the adapter can permanently couple a first male Luer fitting to a second male ISO 80639-6 compliant fitting.
Abstract:
A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator is positioned to extend proximally in the interior cavity and support a seal member positioned thereon in the interior cavity. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. The seal member may be configured for multi-use and include a biasing member that moves the seal member to force the membrane back over the actuator to close the membrane.
Abstract:
An infusion pump system includes at least one reservoir having a reservoir volume, and an infusion pump including a pumping mechanism operably coupled to the at least one reservoir, a processor including a memory and configured to control operation of the pumping mechanism, and a calculation module configured to determine at least one characteristic about the at least one reservoir.
