This disclosure generally relates to medical devices that include a sensor transmitter assembly that includes a sensor assembly including a sensor module where a first sensor including a first sensor head having at least one first sensor contact pad is combined with a second sensor including a second sensor head having at least one second sensor contact pad. The sensor transmitter assembly also includes a transmitter assembly positioned on a top of the sensor assembly to form a single unit, the transmitter assembly having at least one transmitter contact disposed on a base of the transmitter assembly, where the first sensor contact pad(s) and the second sensor form a connection path with the transmitter contact(s).

Sensor connections

A medical sensor device includes a sensor assembly including an underside surface for attachment against a patient's skin, a sensor portion to detect a characteristic of the patient, and sensor assembly contacts which in operation carry signals representing the detected characteristic. The device also includes a transmitter assembly removably engageable with the sensor assembly and including circuitry to take the signals from the sensor assembly contacts and to transmit readings of the detected characteristic to external equipment. The device also includes mechanical interface components on the sensor assembly and the transmitter assembly which allow the transmitter assembly to be brought into abutment with the sensor assembly at a first angular position via relative axial movement between them, and then allow a relative rotation of the assemblies with respect to one another towards a second angular position and presents axial separation of the assemblies in the second angular position.

Sensor and transmitter product

A simple, disposable sensing device for sensing an analyte is housed in a single case. The sensing device can transmit sensor data to monitoring device(s). The sensing device includes: a case having a lower major wall adapted to be mounted against a patient's skin, and an upper opposing major wall; a sensor extending from the case and having a distal end sensitive to the analyte to produce an electrical signal, and a proximal end within the case having electrical contacts; a printed circuit board assembly within the case supported by one of the major walls to receive the electrical signal via the electrical contacts; and an elastomeric pad disposed in the case and biased by the other major wall to urge the proximal end of the sensor into contact with the printed circuit board assembly and maintain an electrical connection between the electrical contacts and the printed circuit board assembly.

Analyte sensor

A fluid channel module for an infusion set component of a fluid infusion device that delivers a fluid to a patient includes a body section comprising coupling features to mate with a base of the infusion set component. The fluid channel module includes an interior fluid flow channel formed within the body section to receive the fluid from the fluid infusion device. The fluid channel module includes a conduit having a first end in fluid communication with the interior fluid flow channel, and having a second end to deliver the fluid to the patient.

Infusion set component with modular fluid channel element

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

Insertion device

A sensor set is provided for sensing of a body characteristic, such as glucose. The sensor set includes a mounting base for the sensor and a connector to connect to the mounting base and has an improved structure for connecting the mounting base to the connector. The connector may contain sensor electronics for wired or wireless communication to an external monitor or display. The mounting base includes latch arms and the connector adapted to fit and lock into latch recesses on the connector and includes anti-rotation arms adapted to fit into anti-rotation arm recesses on the connector.

Sensor set

A sensor set is provided for sensing of a body characteristic, such as glucose. The sensor set includes a mounting base for the sensor including a shim adapted to prevent pull up of the sensor and a connector to connect to the mounting base and has an improved structure for connecting the mounting base to the connector. The connector may contain sensor electronics for wired or wireless communication to an external monitor or display. The mounting base includes latch arms and the connector adapted to fit and lock into latch recesses on the connector and includes anti-rotation arms adapted to fit into anti-rotation arm recesses on the connector.

An infusion set component of a fluid infusion device and/or a fluid infusion port component for delivery of fluid to a patient is compatible with a cooperating fluid channel module. The fluid channel module includes a body section having coupling features to mate with a base of the component. The fluid channel module also includes an interior fluid flow channel formed within the body section to receive fluid from the fluid infusion device and/or from a syringe or pen delivery device. The fluid channel module also includes a conduit having a first end in fluid communication with the interior fluid flow channel, and having a second end to deliver the fluid to the patient.

This disclosure generally relates to medical devices that include a transmitter assembly positioned on top of a sensor assembly. A sensor assembly includes a sensor base having a bottom surface and a top surface having an interface. The interface accommodates a sensor stack that includes at least one sensor head having electrical contact pads connected to an elastomeric connector. The sensor assembly further includes a mounting base having a first side that attaches to the bottom surface of the sensor base, and a second side that adheres to a patient's skin. A transmitter assembly includes a transmitter shell and a transmitter cap having an interface that engages with the sensor base. Also, the transmitter assembly includes electrical contacts disposed on the transmitter cap that connect with the electrical contact pad(s) of the sensor assembly.

A monitor system to monitor a characteristic of a user is disclosed. A monitor system includes a sensor producing signals indicative of glucose characteristics within the user. The sensor has a connector with a plurality of contacts, at least two contacts being shorted by a fuse trace. The monitor system further includes an electronics package with a package housing. The package housing contains a battery, a package port interfaced with the connector to receive signals from the sensor, and a package processor to process the signals from the sensor. Further included in the monitor system is a fuse system controlled by the package processor that includes a fuse timer, wherein the fuse trace is destroyed after the fuse timer reaches a threshold value.
