Abstract
An electrochemical sensor apparatus for introducing a needle electrode into the skin of a subject to contact a biological fluid or a tissue in the subject and detect a target analyte. The apparatus has a movable portion which urges the needle electrode in the subject's skin and a power management function to supply operational power to the sensor electronics around the time that the apparatus is deployed.
Claims71
Apparatus for contacting one or more projections to the skin of a subject, the apparatus comprising:
- one or more projecting portions, each configured to penetrate the skin;
- a skin contacting portion defining a skin contacting surface and one or more spaces allowing the one or more projecting portions to extend therethrough;
- a movable portion configured to move the one or more projecting portions from a first position behind the skin contacting surface to a second position proud of the skin contacting surface;
- electronics configured to effect a function of the apparatus comprising a power source;
- an enclosure about the electronics and the power source;
- and
- a power regulator,
- wherein the power regulator is initially in a first state whereby the electronics consumes no power or a non-operational amount of power and is actuatable so as to adopt a second state whereby the electronics consumes an operational amount of power, and wherein the apparatus is configured such that the power regulator is caused to transition from the first state to the second state in the course of normal deployment of the apparatus and absent any dedicated powering-up act being performed by a user.

A method for deploying an apparatus comprising:
- providing an apparatus for contacting one or more projections to the skin of a subject, the apparatus comprising:
- one or more projecting portions, each configured to penetrate the skin;
- a skin contacting portion defining a skin contacting surface and one or more spaces allowing the one or more projecting portions to extend therethrough;
- a movable portion configured to move the one or more projecting portions from a first position behind the skin contacting surface to a second position proud of the skin contacting surface;
- electronics configured to effect a function of the apparatus comprising a power source;
- an enclosure about the electronics and the power source;
- and
- a power regulator,
- wherein the power regulator is initially in a first state whereby the electronics consumes no power or a non-operational amount of power and is actuatable so as to adopt a second state whereby the electronics consumes an operational amount of power, and wherein the apparatus is configured such that the power regulator is caused to transition from the first state to the second state in the course of normal deployment of the apparatus and absent any dedicated powering-up act being performed by a user, and
- in response to an act performed by a user in the course of normal deployment of the apparatus, allowing the power regulator to transition from the first state to the second state.
