20140276569 | SYSTEM AND METHOD FOR DETECTING PRESENCE OF AN INFUSION CARTRIDGE IN AN INFUSION PUMP - Infusion devices, systems, and methods can detect a presence or absence of an infusion cartridge in an infusion pump. Embodiments may include a loading sequence, recording loading pulse width modulation (PWM) commands applied to an infusion pump motor during the loading sequence, setting a value of threshold PWM commands based on the commands applied during the loading sequence and comparing values of operational PWM commands applied during pumping operations to the value of the threshold PWM commands.

20140276531 | SYSTEM AND METHOD FOR MAXIMUM INSULIN PUMP BOLUS OVERRIDE - An ambulatory infusion pump can include a maximum bolus override procedure. When a bolus amount greater than a maximum bolus amount is requested, the pump can provide an alert indicating that the amount requested exceeds the maximum bolus amount. If the user confirms the request in response to the alert, the bolus amount can be delivered to the user. The amount delivered in response to the confirmation can be a first portion of the bolus amount. A reminder can then be provided that a second portion of the bolus amount that is a remaining portion of the requested bolus amount was also requested. If a second confirmation is received in response to the alert, the second portion of the bolus amount can also delivered to the user. | 09-18-2014 |

20140273042 | PREDICTIVE CALIBRATION - A portable medical monitor system generates a current calibration curve for generating the estimate of the level of an analyte, such as glucose, being monitored. The current calibration curve is based on at least two measured data values of the level being monitored. The system determines a transformation function based on the calibration curve and at least one preceding calibration curve such that the transformation function produces a predictive calibration curve, and generates an estimated level value of the level being monitored, based on sensor output from a sensor associated with the portable medical monitor system, in accordance with the predictive calibration curve. | 09-18-2014 |
20130332874 | PREVENTING INADVERTENT CHANGES IN AMBULATORY MEDICAL DEVICES - A portable medical device is operated in an active mode in which the device receives a user input at an input interlace and provides the received user input to a processor of the device. The active mode is terminated and the device is operated in a safe mode, in which the received user input is not provided to the processor and/or one or more device function is disabled, in response to determining that the received user input was received in an out of bounds region of the input interface. The safe mode is terminated in response to receiving a predetermined user input comprising an activation input. | 12-12-2013 |

20130283196 | SYSTEM AND METHOD FOR REDUCTION OF INADVERTENT ACTIVATION OF MEDICAL DEVICE DURING MANIPULATION - Inadvertent activation of a portable medical device such as an ambulatory infusion pump can be reduced by locking a touchscreen of the device when it is indicated that an uninterrupted operation is to be performed. When a processor receives a device operation input from the touchscreen that indicates an uninterrupted operation is to be performed on the portable device, the touchscreen is automatically locked such that touch input at the touchscreen is not processed by the processor to navigate between or among menu screens or set pump parameters. Following completion of the uninterrupted operation, the touchscreen can be unlocked. In one embodiment, the touchscreen can be unlocked by selection of an unlock icon on the touchscreen. | 10-24-2013 |
20130159456 | THERAPY MANAGEMENT SYSTEM - Stored data is accessed over a computer network through a network data manager. Data may be stored and transferred to the network data manager from a product device using an uploader application. In one aspect, a request message containing an access request or identifier is received at the network data manager from a client device for access to a data storage facility. If the network data manager determines the access requestor identifier is associated with a data record that identifies a product device having a registration record, the network data manager transmits a data link to the client device to provide access to the data record by the client device over the computer network. | 06-20-2013 |
20130131630 | PROGRAMMABLE INSULIN PUMP - An apparatus for delivering a bolus of a medical agent to a patient. The apparatus comprises a pump mechanism, a data input device, and a processor in data communication with the keypad and arranged to control the pump mechanism. The processor is programmed to receive data specifying a bolus amount through the data port, receive data regarding duration through the data port, receive a percentage through the data port, the percentage defining a portion of the bolus amount to deliver immediately upon executing a deliver command and a remainder of the bolus amount to deliver over the duration upon executing a deliver command, and execute the deliver command thereby controlling the pump mechanism to deliver the bolus. Also a method of temporarily adjusting the delivery rate of an infusion pump. The infusion pump is programmed to deliver a basal rate. The method comprises prompting a user to select whether to enter the temporary rate as a percent of the current delivery rate or as a new delivery rate; entering into the pump a period of time having a beginning and an end; entering into the pump a temporary basal rate; and delivering the therapeutic agent at a delivery rate substantially equal to the temporary basal rate during the period of time. | 05-23-2013 |
