Energy supply for fluid dispensing device
First Claim
1. A portable ambulatory therapeutic fluid dispensing device for infusing a therapeutic fluid into a body of a user and optionally for sensing an analyte within the body, the device comprising a device housing including a disposable part housing and a separate reusable part housing connectable to the disposable part housing;
- wherein the disposable part housing comprises;
a reservoir for containing a therapeutic fluid;
a source of energy to energize the device, the source of energy comprising at least one electrochemical cell configured to produce electrical energy upon exposure of the cell to air; and
a seal to prevent exposure of the at least one cell to air when the source of energy is not in use and configured to expose the at least one cell to air prior to energizing the device;
wherein the reusable part housing comprises;
at least a portion of a driving mechanism; and
a processor;
wherein the device housing has at least one air vent opening configured to expose the source of energy to air, and a second seal to prevent entry of air into at least one of the disposable part housing and the reusable part housing through the at least one air vent opening when the device is not in operation; and
wherein the device is operable upon connecting the disposable part housing and the reusable part housing such that the source of energy is exposed to air through the vent and electrical connectivity occurs between the source of energy and the at least a portion of the driving mechanism and the processor.

Abstract
Disclosed is a portable fluid dispensing device for infusing a fluid into the body of a user and/or for sensing an analyte within the body. The device includes at least one housing to retain a source of energy to energize the device, the source of energy comprising at least one electrochemical cell to produce electrical energy upon exposure of the cell to air, and a seal to prevent exposure of the at least one cell to air when the source of energy is not in use and to enable exposure of the at least one cell to air prior to energizing the device with the source of energy. The at least one housing includes an opening to provide access to the seal to enable actuation of the seal to control exposure of the at least one cell to air.

22. A portable fluid dispensing device for infusing a fluid into a body of a user and optionally for sensing a bodily analyte, the device comprising:
-
a dispensing unit comprising a reservoir, a pump, and a first housing for housing the reservoir and the pump; and a separate cradle unit connectable to the dispensing unit, the cradle unit comprising; a second housing for securing the dispensing unit to the body of the user; a source of energy to energize the dispensing unit, the source of energy comprising at least one electrochemical cell for producing electrical energy upon exposure of the cell to air; at least one vent to expose the source of energy to air; a seal for substantially preventing exposure of the at least one electrochemical cell to air when the source of energy is not in use and for exposing the at least one cell to air prior to energizing the dispensing unit with the source of energy; a semi-permeable membrane placed within and/or adjacent the at least one vent, wherein the semi-permeable membrane is configured for entry of air into the cradle unit and configured for substantially preventing entry of at least some other materials into the cradle unit, wherein the dispensing unit is operable upon connection to the cradle unit via establishment of electrical communication between the source of energy and the dispensing unit. - View Dependent Claims (23, 24)
