Insertion set for transcutaneous sensor with connector lock mechanism
First Claim
1. A connector for connecting a sensor set to a monitor device, wherein the sensor set includes:
- a mounting base adapted for mounting onto a patient'"'"'s skin, the mounting base including a connector fitting generally at a rear end of the mounting base, wherein the connector fitting of the sensor set includes a tubular element having a central bore formed therein for pass through reception of a portion of the sensor, and wherein the mounting base further includes including a lock mechanism for releasable coupling to the connector; and
a sensor having at least one sensor electrode thereon for generating at least one electrical signal representative of at least one patient condition, the sensor including at least one contact pad conductively coupled to the at least one sensor electrode, the sensor being coupled to the mounting base;
wherein the connector is adapted for interengageable coupling with the lock mechanism on the mounting base of the sensor set,wherein the connector includes at least one connector contact that is electrically coupled to the at least one contact pad of the sensor when the mounting base of the sensor set is coupled to the connector,wherein the at least one connector contact receives the at least one electrical signal; and
wherein the tubular element of the sensor set is for mating with a corresponding tubular recess formed in the connector, the connector fitting of the sensor set further having a recessed seat to support and retain the sensor, the recessed seat defined to fit within a recess in the connector.

Abstract
An improved insertion set is provided for transcutaneous placement of a sensor such as a glucose sensor at a selected site within the body of a patient. The insertion set comprises a mounting base defining an upwardly open channel for receiving and supporting a flexible thin film sensor, in combination with a cap assembled with said mounting base to capture and retain a proximal end of the sensor within said channel. The sensor further includes a distal segment with sensor electrodes thereon which protrudes from the mounting base for transcutaneous placement, wherein the sensor distal segment is slidably carried by a slotted insertion needle fitted through the assembled base and cap. Placement of the insertion set against the patient'"'"'s skin causes the insertion needle to pierce the skin to carry the sensor electrodes to the desired subcutaneous site, after which the insertion needle can be slidably withdrawn from the insertion set. The mounting base further includes a fitting and related snap latch members for mated slide-fit releasable coupling of conductive contact pads on a proximal end of the sensor to a cable connector for transmitting sensor signals to a suitable monitoring device.
