Disclosed are methods and corresponding systems and devices for controlling which communication interface is used for communication in a wireless body area network of medical devices. In some aspects, a security level for data to be transmitted from a first device to a second device is determined. The first device includes a first communication interface and a second communication interface. Signals communicated over the second communication interface (e.g., a near-field communication interface) have a shorter range compared to the first communication interface (e.g., a far-field communication interface). The data is transmitted using the second communication interface based on determining that the security level for the data is higher than that associated with the first communication interface. In some instances, transmission of the data involves switching to the second communication interface after establishing an initial communication channel using the first communication interface.

Controlling communications between devices of a wireless body area network for a medical device system

A method and system are provided for controlling which communication interface is used for communication between devices that are configurable to be part of a wireless body area network (BAN) for a medical device system depending on their respective locations with respect to a first device. Based on a security secret shared between the first device and a second device, a secure communication channel can be established between the first device and the second device when the second device is located in a coverage region of the wireless body area network. A controller can determine, whether a quality of service (QoS) over the secure communication channel is greater than or equal to a first threshold. In response to the controller determining that the QoS is greater than or equal to the first threshold, data can be communicated from the first device via magnetic signals using a first BAN communication interface.

Method and system for controlling communication between devices of a wireless body area network for a medical device system

A method and system are provided for controlling which communication interface of a plurality of communication interfaces is used for communication between a plurality of devices that can be part of a wireless body area network for a medical device system. The communication interfaces can include a body area network communication interface and a far field communication interface. A controller can determine whether a first device is able to establish a communication link with a second device that is located in a coverage region of the wireless body area network using a first body area network communication interface. If so, the controller can determine whether a quality of service over the communication link is greater than or equal to a first threshold, and if so, the first body area network communication interface can be used to communicate data from the first device to the second device via magnetic signals.

Method and system for controlling communication between devices of a wireless body area network for an medical device system

A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

Smart connection interface

A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism having an inlet and an outlet, a first flow path in fluid communication with the inlet and at least partially defined by structure compatible with fluid cartridge modules containing medication fluid, a second flow path in fluid communication with the outlet and terminating at a subcutaneous conduit for a body, and a drive motor that actuates the pump mechanism. An exemplary operating method detects a first installation of a fluid cartridge module in the housing. The detecting occurs after the housing has been affixed to the body and after the subcutaneous conduit has been inserted into the body. In response to the detecting, the operating method initiates an automatic priming operation to prepare the device for delivery of the medication fluid to the body.

Fluid infusion patch pump device with automatic fluid system priming feature

A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism, a transcutaneous conduit assembly having a fluid conduit coupled to the pump mechanism, and an insertion mechanism for inserting the conduit into the body. An exemplary method begins by detecting a first installation of a fluid cartridge module in the housing, wherein the detecting occurs after the housing has been affixed to the body. In response to the detecting, the operating method automatically activates the insertion mechanism to insert the fluid conduit into the body.

Fluid infusion patch pump device with automatic startup feature

A fluid infusion device includes a fluid pump mechanism having a rotor and a stator. The rotor includes an optically detectable feature, a reference surface, and a cam element rising from the reference surface. The stator includes a cam element having a stator cam surface. The cam elements cooperate to axially displace the rotor as a function of angular position of the rotor, wherein the detectable feature rotates and axially translates as a function of angular position of the rotor. A biasing element provides force to urge the rotor cam element toward the stator cam element and toward the reference surface. A drive motor actuates the rotor to pump medication fluid from a fluid cartridge module to a body, via a subcutaneous conduit. An optical detection circuit interrogates the detectable feature during operation of the fluid pump mechanism to determine an operating condition of the fluid pump mechanism.
