## Abstract

An apparatus for use with an access port implanted subcutaneously in a living body includes a locator assembly and a base plate. The locator assembly includes a port sensor configured to sense an aspect of the access port, a controller configured to determine a location of the access port based on the aspect, and an output device configured to provide user feedback based on the determined location of the access port. The locator assembly also includes an outer housing having a device side coupler. The apparatus furthermore includes a base plate having an adhesive flange configured to adhere the base plate to a skin of the living body, and a base coupler on the adhesive flange and configured to cooperate with the device side coupler such that the base plate is attachable and detachable from the locator assembly.

## Claims

### Claim 1

An apparatus for use with an access port implanted subcutaneously in a living body, the apparatus comprising:
a locator assembly including:
a port sensor configured to sense an aspect of the access port;
a controller configured to determine a location of the access port based on the aspect sensed by the port sensor; and
an output device configured to provide feedback to a user,
wherein the controller is further configured to instruct the output device to provide the feedback to the user based on the determined location of the access port,
the locator assembly further including an outer housing, wherein the controller is in the outer housing, the outer housing including a device side coupler; and
a base plate including:
an adhesive flange configured to adhere the base plate to a skin of the living body, the adhesive flange including at least one opening; and
a base coupler on the adhesive flange and including at least one opening, the base coupler configured to cooperate with the device side coupler such that the base plate is attachable and detachable from the locator assembly by cooperation of the device side coupler with the base coupler,
wherein when the base plate is attached to the locator assembly, the at least one opening of the adhesive flange aligns with the at least one opening of the base coupler and the port sensor such that the port sensor senses the aspect of the access port through the at least one opening of the adhesive flange and the at least one opening of the base coupler.

### Claim 2 (depends on 1)

The apparatus of claim 1, the locator assembly further comprising:
a skin sensor configured to sense a proximity of the apparatus to the skin through the at least one opening of the adhesive flange and the at least one opening of the base coupler.

wherein the plurality of flexible fingers and the protruding groove cooperate with each other to attach and detach the base coupler from the device side coupler.

### Claim 11 (depends on 10)

The apparatus of claim 10, wherein the plurality of flexible fingers of the base coupler is configured to cooperate with a buttress of a medication delivery device to restrict detachment of the medication delivery device from the base plate.

### Claim 12 (depends on 1)

The apparatus of claim 1, wherein the controller is further configured to determine, based on the sensed aspect of the port sensor, that the base plate has an incompatibility with the access port, and wherein the feedback further includes an indication of the incompatibility.

### Claim 13 (depends on 12)

The apparatus of claim 12, wherein the controller determines that the base plate has the incompatibility based on a determined manufacturer of the access port.

### Claim 14 (depends on 1)

The apparatus of claim 1, wherein the base coupler is configured to cooperate only with access ports manufactured by a predetermined manufacturer.

### Claim 15 (depends on 1)

The apparatus of claim 1, wherein a bottom side of the locator assembly includes a port relief area to accommodate a prominence of the access port under the skin.

### Claim 16 (depends on 1)

The apparatus of claim 1, wherein:
the locator assembly includes a plurality of skin sensors; and
the at least one opening of the adhesive flange includes a plurality of openings respectively corresponding to the plurality of skin sensors for the plurality of skin sensors to sense the skin therethrough.
