An infusion device is configured to monitor delivery conditions associated with a medication infusion, identify an infusion set used with the infusion device, determine that the delivery conditions modify operation of infusion set, and determine correction factors for modifying an operation of the device based on a modification of the operation of the infusion set by the monitored delivery conditions. According to various implementations, an operating parameter of the infusion device may be modified, including modifying a threshold for when the infusion device will experience an alarm condition.

An infusion pump includes a housing, a wireless transceiver, a pump motor mounted within the housing, a location sensor configured to provide information associated with a location of the infusion pump, a battery conductively coupled to the wireless transceiver, the pump motor, the location sensor and processor(s), and memory. The infusion pump is configured to monitor, using the location sensor, a geofence parameter of the infusion pump, determine a change in the location of the infusion pump based on the geofence parameter, identify an operation mode of the infusion pump associated with the geofence parameter, and automatically switch, responsive to the changed location, the operation mode of the infusion pump from a first mode currently programmed for care of a patient to a second mode, the second mode using different parameters than the first mode to control elements of the infusion pump.

An infusion pump is secured within a lockbox configured to enclose and prevent access to the infusion pump and a medication receptacle of the infusion pump, the lockbox including a lockbox control interface configured to obtain authorization for access to the lockbox from a pump communication interface of the infusion pump and enclosed within the lockbox. The lockbox control interface is electronically coupled with the pump communication interface. Transmission of a wireless credential is made to the pump communication interface by way of being received at the lockbox control interface or at the pump interface through the lockbox. The lockbox control interface receives the authorization from the pump communication interface for access based on the wireless credential and performs an action according to the received authorization for access. Action includes unlocking the lockbox or the lockbox control interface extending the pump's interface to the authorized user.

A single use disposable elapsed time indicator and methods for using same can include an indicator having a chamber and a longitudinal channel for receiving a volatile fluid. A sponge is located and seated in the longitudinal channel and configured to allow evaporation of volatile fluid from within the longitudinal channel to an exterior of the longitudinal channel. A spring is included in the longitudinal channel which presses against an end of the chamber and against a plunger that is seated and moveable in the longitudinal channel along a longitudinal axis thereof. The spring is configured to exert force on and move the plunger from a first end of the chamber toward a second end of the chamber along the longitudinal axis in the longitudinal channel as volatile fluid in the longitudinal channel evaporates through the sponge. The movement of the plunger thereby marks elapsed time along a graded scale.

A method for connecting a tubing assembly (150) to a tubing system component. The tubing assembly comprises a tubing (152) and a tubing assembly connector (158) circumferentially disposed around a portion of the tubing. A portion of the tubing assembly connector is disposed within a component connector (132) of the tubing system component. A support ring (270) is disposed within a lumen (151) of the tubing to structurally support the tubing during subsequent molding. A coupling portion (160) is molded over the tubing assembly connector and the component connector, thereby forming a secure and sealed connection.

A syringe pump determines, upon receiving a new syringe, that at least a first portion of a predetermined amount of a first fluid was previously delivered by the syringe pump according to a first fluid delivery order before the new syringe was loaded into the syringe pump, and determines a second portion of the first fluid remaining to be delivered to complete the predetermined amount of the first fluid for the first fluid delivery order. A delivery of a second fluid is initiated by the syringe pump and, when an amount of the second fluid delivered from the new syringe satisfies the second portion of the first fluid remaining to be delivered, the pump automatically, without user intervention, indicates the first fluid delivery order as being complete, de-associates the first fluid delivery order from the syringe pump, and associates the syringe pump with the second fluid delivery order.
