Infusion systems and methods for prospective closed-loop adjustments

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device capable of delivering fluid to a patient involves predicting, by a control system associated with the infusion device, a future occurrence of an event based at least in part on historical data associated with the patient, and prior to the future occurrence of the event, automatically adjusting a control parameter for operating the infusion device based at least in part on the event and automatically operating an actuation arrangement of the infusion device to deliver the fluid to the patient based at least in part on a current measurement of the physiological condition and the adjusted control parameter.

INSULIN PUMP INFUSION CONTROL METHOD

An insulin pump bolus infusion control method. A control module of a pump body controls the pump body to start a bolus infusion control mode after receiving a function starting signal; in the bolus infusion control mode, a bolus key of a control terminal or a bolus key of an insulin pump body sends an infusion dosage signal to the control module by means of one or more operations; if the control module receives a confirmation signal within a predetermined period of time, then the control module controls the pump body to start bolus infusion; and if the control module receives a cancellation signal or does not receive the confirmation signal within a predetermined period of time, then the control module controls the pump body to exit the bolus infusion mode. Using the method enables an insulin pump to execute a more reasonable control when carrying out the bolus infusion, i.e., starting, setting and implementation of the bolus infusion, and enables a simple and quick operation.

SKIN SENSOR TRIGGERING SIGNAL
20230145128 · 2023-05-11 ·

The present disclosure provides a medicament delivery device including a housing, a skin sensor positioned at least partially within the housing, and a transmitter positioned within the housing. The medicament delivery device is configured to determine, via the skin sensor, whether or not the medicament delivery device is attached to the skin of the user. In response to a determination that the medicament delivery device is attached to the skin of the user, the medicament delivery device prevents transmission of unique identification data associated with the medicament delivery device and/or the user from the transmitter. In response to a determination that the medicament delivery device is not attached to the skin of the user, the medicament delivery device transmits, via the transmitter, the unique identification data to one or more external receivers.

System and method for switching between closed loop and open loop control of an ambulatory infusion pump
11638781 · 2023-05-02 · ·

An infusion pump system providing therapy to a patient in a closed-loop or semi-closed loop mode can safely automatically revert to open-loop therapy. The system stores a default open-loop basal rate profile in memory. The system also continually tracks the insulin on board for the patient over a plurality of closed-loop therapy intervals. When an error or event occurs requiring reversion to open-loop therapy, the system automatically provides therapy according to the open-loop basal rate profile and the tracked insulin on board amount.

Anti-C5 antibody dispensing injector and method of injection

An injector includes an injector housing, an activation button assembly movably mounted to the injector housing and operatively connected to the injection needle, and a cartridge door movably mounted to the injector housing between an open position and a closed position. A deflectable interference member engaging the rear end flange of the cartridge has a resting position configured to limit an insertion depth of a cartridge into an interior channel of the cartridge door to a sealed position, wherein the cartridge piercing needle does not fully penetrate a pierceable septum of the cartridge. The cartridge door includes an interior channel having a cartridge mounted therein. The cartridge includes a substance to be dispensed. The substance includes an anti-C5 antibody or antigen binding fragment thereof, and optionally further includes a recombinant human hyaluronidase enzyme. A method of treating a complement associated condition using an injector thereof. A method of dispensing a substance from an injector thereof.

Method and system including displaying a first representation of a medication treatment parameter profile, displaying a first representation of a physiological profile associated with the medication treatment parameter profile, detecting a modification to a segment of the medication treatment parameter profile, displaying a modified representation of the medication treatment parameter profile and the physiological profile based on the detected modification to the segment of the medication treatment parameter profile, modifying an attribute of the first representation of the medication treatment parameter profile, and modifying an attribute of the first representation of the physiological profile are provided.

Fluid infusion systems

A fluid infusion system includes a housing configured to be adhesively coupled to an anatomy of the user. The housing comprises a communication device configured to wirelessly communicate a physiological characteristic to a communication component of a fluid infusion device. The fluid infusion system includes a fluid flow path from the fluid infusion device into the anatomy of the user, and the fluid flow path is configured to extend from the housing for insertion into the anatomy of the user.

RAPID FLUID DELIVERY SYSTEM

A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.

INFUSION PUMP ASSEMBLY

A fluid connector assembly. The fluid connector assembly includes a tab portion including a slot; a plug portion slidably connected to the tab portion the plug portion comprising a fluid path and a disc, the disc configured to seat within the slot; a catch feature located on a first end of the tab portion and configured to interact with a reservoir; and a latching feature located on a second end of the tab portion, the latching feature configured to interact and lock onto the reservoir, wherein force applied to the plug portion may overcome a threshold force and unseat the disc from the slot wherein the plug portion moves with respect to the tab portion.

ANALYTE SENSOR
