The device comprise a self-pressurized reservoir for storing the medication for subsequent delivery to a patient, a needle for delivering the medication to the patient subcutaneously, a first MEMS device configured as a microvalve in a fluid path between the self-pressurized reservoir and needle for controlling flowrate of medication through the needle as the self-pressurized reservoir discharges, a second MEMS device configured as a micropump configured to increase flowrate of the medication in the fluid path to ensure a constant flowrate in the fluid path as the self-pressurized discharges independent of orientation of the device, a flow sensor configured to measure flowrate in the fluid path for controlling microvalve and micropump, and control circuitry connected to the microvalve, micropump and flow sensor for controlling operation of the micropump and microvalve.

A method for improved controlling of a thermic infusion system having a one tubal segment and a thermal element to heat an infusion fluid carried within the tubal segment, and having at least one sensor positioned within the thermic infusion system comprising regulating energy provided to the sensor for a first period of time to sense a self-heating effect of the at least one sensor due to a dry tube; responsive to detecting a dry tube, preventing energizing the thermal element; responsive to detecting a non-dry tube, regulating energy provided to the sensor for a second period of time to sense a temperature of an infusion fluid carried within the at least one tubal segment.

An apparatus including tubing sets, a modular constraint assembly, and methods of use are described for deliver a therapeutic medication to a patient, the apparatus can have a controller and a sensor. The controller is configured to receive data from the sensor, and to start and stop delivery of the therapeutic medication to the patient in response to data received from the sensor. In addition, apparatus, systems and methods are disclosed, which are configured to deliver a therapeutic medication to a patient. The apparatus, system and methods use a reservoir, a patient interface, a tubing set, a modular constraint assembly connected to the tubing sets, and a fluid pump, and the components are configured to provide a calibrated flow rate based upon specific characteristics of the therapeutic medications passing through and internal lumen of the tubing set.

Infusion devices, systems, and related operating methods are provided. A method of detecting an occlusion in a fluid path involves a control module of an infusion device operating a driver module to provide energy to an actuation arrangement to achieve a commanded actuation state, wherein the actuation arrangement is coupled to a plunger configured to deliver fluid via the fluid path, obtaining a measured actuation state of the actuation arrangement via a sensing arrangement, and detecting an occlusion condition based on a relationship between the commanded actuation state and the measured actuation state.

An injection system is described that receives, from one or more sensors, a first group of one or more signals indicating a current volume of injection fluid dispensed from a fluid reservoir at a first time. The injection system determines, based on the first group of one or more signals, that a difference between a dispensed volume limit and the current volume of the injection fluid dispensed from the fluid reservoir at the first time is less than a necessary volume of fluid required to complete both a systolic injection phase and a diastolic injection phase. The injection system further, responsive to determining that the difference is less than the necessary volume of fluid required to complete both the systolic injection phase and the diastolic injection phase, controls the injection system to refrain from performing each of the systolic injection phase and the diastolic injection phase.

A system, method, and computer program product for identifying device connections in a connection area includes receiving a plurality of physical parameters of a plurality of devices from a plurality of transmission sources in a connection area, wherein the plurality of physical parameters indicates physical states of the plurality of devices. At least one physical connection state is determined between the plurality of devices based on the plurality of physical parameters of the plurality of devices.

The present disclosure relates to wearable injection devices that comprise flexible elements. Exemplary devices can comprise flexible reservoirs, flexible housings, and flexible metering mechanisms. The flexible elements of the present disclosure provide improved wearable injection devices with small heights, low profiles, and streamlined, flexible cases that can withstand impact without experiencing adverse performance effects or tearing off of the patient.

A dual lumen IV administration set includes a first lumen having an inner diameter of a first value. A second lumen is paired with the first lumen, and the second lumen has an inner diameter of a second value that is greater than the first value. A flow merger merges flow output from a distal end of the first lumen and flow output from a distal end of the second lumen to form a single flow output in an exit lumen. An injection port intersects the first lumen, thereby providing injection access to flow therethrough, prior to merging with the flow output of the second lumen.
