A physiological sensor history backfill system and method including a method of sensor history backfill for a local base device operable to wirelessly communicate with a physiological sensor connected to a patient, the method including: obtaining physiological readings for the patient at a predetermined interval; storing the physiological readings at the physiological sensor as sensor physiological readings; storing the physiological readings at the local base device as historic physiological readings; obtaining a current physiological reading for the patient; transmitting the current physiological reading to the local base device in a current reading message; detecting a record gap in the historic physiological readings between the current physiological reading and the historic physiological readings; and filling the record gap in the historic physiological readings with sensor physiological readings from the physiological sensor when the current reading message does not include the sensor physiological readings to fill the record gap.

Physiological sensor history backfill system and method

Infusion systems, infusion devices, and related operating methods are provided. An exemplary infusion device includes a motor operable to deliver fluid to a body of a user, a first control module to enable input power for the motor and provide a dosage command for operating the motor, and a second control module coupled to the first control module to receive the dosage command and operate the motor using at least a portion of the input power based at least in part on the dosage command. One of the first control module and the second control module detects an anomalous condition, and in response, disables the input power to the motor, stores diagnostic information for the anomalous condition in its internal memory, and automatically resets thereafter.

Error handling in infusion devices with distributed motor control and related operating methods

An infusion system to administer fluid is disclosed. The infusion system includes an infusion pump having a pump processor, a pump memory and a pump radio to enable bi-directional communication. The pump memory stores a plurality of fingerprint tokens and security conditions. The infusion system includes a controller with a processor, a controller memory and a controller radio to transmit and receive communication from the pump radio. The controller includes a fingerprint scanner and a graphical user interface (GUI) and controls to manipulate the GUI. The GUI and fingerprint scanner enable the controller to scan and determine tokens based on scanned fingerprints. Additionally, communication between the infusion pump and the controller establish relative proximity between the infusion pump and the controller such that when the relative proximity exceeds a threshold distance at least one of the plurality of security conditions is automatically matched.

Fingerprint enhanced authentication for medical devices in wireless networks

Infusion systems, infusion devices, and related operating methods are provided. An exemplary infusion device includes a motor operable to deliver fluid to a body of a user, a first control module, and a second control module. The first control module and the second control module are coupled to one another. The first control module enables input power for the motor in accordance with a handshaking sequence of communications between the first control module and the second control module and provides a dosage command to the second control module, with the second control module operating the motor using the input power based on the dosage command in accordance with the handshaking sequence of communications.

A medical therapy system including liquid detection is disclosed. A medical therapy includes a case with an interior and an exterior. Within the interior of the case is the liquid detection system that includes a first electrode set with a first positive electrode and a first negative electrode. The liquid detection system further includes an impedance measurement circuit coupled to the first electrode set to determine impedance values between the first positive electrode and the first negative electrode. A threshold detector compares impedance values between the first electrode set to a first threshold impedance. A microprocessor is programmed to initiate an alarm when measured impedance from the first electrode set is below the first threshold impedance.

Apparatus are provided for infusion devices and related control systems and methods. In one embodiment, an infusion device includes a voided portion adapted to receive a shaft portion that includes a shaft coupled to a plunger of a reservoir. The shaft portion includes a detectable feature having an optically detectable pattern such as gray code, and the infusion device includes a sensing arrangement having an optical sensor proximate the voided portion to sense the detectable feature. In some embodiments, a control module is coupled to the sensing arrangement to determine a remaining amount of fluid in the reservoir based at least in part on the sensed position of the detectable feature. In embodiments, the optical sensor detects the sensed position of the shaft based on the detectable feature only when the reservoir is replaced and/or after each delivery of fluid to reduce power consumption.

Reservoir fluid volume estimator and medical device incorporating same

An infusion system to administer fluid is disclosed. The infusion system to administer fluid includes an infusion pump having a pump processor, a pump memory and a pump radio to enable bi-directional communication. The pump radio further includes a configurable attenuator and the pump memory stores a plurality of security modes that configure the attenuator to receive signals of a predetermined strength. The infusion system further includes a controller with a controller processor, a controller memory, and a controller radio to transmit and receive communication from the pump radio. The controller further having a graphical user interface shown on a display, and controls to manipulate the graphical user interface. The controller further being paired with the infusion pump based on pairing data, wherein a security check is performed when the infusion pump receives a suspect signal, the suspect signal not matching the predetermined strength associated with a selected security mode.
