Method and apparatus for providing rechargeable power in data monitoring and management systems
First Claim
1. An apparatus including a data transmission unit, comprising:
- a sensor including an electrical contact portion and an insertion portion, wherein the insertion portion is adapted for transcutaneous positioning under a skin surface of a patient and for contacting biological fluid under the skin surface, the sensor configured to generate multiple analyte related signals during a sensing time period;
a transmitter unit mount including a disposable battery and an adhesive layer provided on a mount surface of the transmitter unit mount, the transmitter unit mount configured to be positioned on the skin surface of a patient such that the adhesive layer is in contact with the skin surface and retains the mount surface of the transmitter unit mount in a substantially fixed position on the skin surface, the transmitter unit mount receiving the electrical contact portion of the sensor when the insertion portion of the sensor is positioned under the skin surface and in fluid contact with the analyte; and
a transmitter unit received by the transmitter unit mount, the transmitter unit including a rechargeable battery, the transmitter unit further configured to establish electrical contact with the electrical contact portion of the sensor, and further, wherein the transmitter unit is configured to draw power from one or more of the disposable battery or the rechargeable battery.

Abstract
Method and apparatus for providing a disposable power supply source integrated into the housing of the transmitter unit mount that is placed on the skin of the patient, and configured to receive the transmitter unit is disclosed. The transmitter unit mount is configured to be disposable with the analyte sensor so that power supply providing power to the transmitter unit is also replaced. The transmitter unit may include a rechargeable battery that is recharged by the power supply unit of the transmitter unit mount when the transmitter is mounted to the transmitter unit mount. Other energy store configurations including single large capacitor (supercap) or a capacitor and DC/DC converter configurations are disclosed.

19. An apparatus, comprising:
-
a housing; an analyte sensor coupled to the housing and configured to generate multiple analyte related signals during the sensing time period; a rechargeable battery provided within the housing; a transmitter unit provided within the housing and coupled to the rechargeable battery, the transmitter unit configured to draw power from the rechargeable battery to transmit the multiple analyte related signals to a remote location; and a transmitter unit mount including a disposable battery disposed therein, the transmitter unit mount configured to removably mate with the housing, the transmitter unit mount including an adhesive layer provided on a mount surface for adhering to a skin surface such that the movement of the skin surface does not substantially affect the position of the transmitter unit mount adhered to the skin surface; wherein the rechargeable battery is configured to recharge from the disposable battery disposed in the transmitter unit mount when the housing is mated with the transmitter unit mount.
