Vented dispensing device and method

摘要

Disclosed is a fluid dispensing device that includes at least one reservoir to hold the therapeutic fluid, at least one other unit requiring communication with ambient air, at least partly, to operate, and at least one housing defining an interior to retain the at least one reservoir and the at least one other unit. The at least one housing has at least one vent port formed on one or more of its walls. The at least one vent port is adapted to direct or communicate air to maintain pressure equilibrium between the air pressure in the interior of the at least one housing and the ambient air pressure outside the at least one housing, and provide communication with the ambient air to the at least one other unit requiring air to enable operation of the at least one other unit.

主权项

1. A fluid dispensing device for delivery of a therapeutic fluid to a user's body, the fluid dispensing device comprising:
a disposable part housing comprising of at least one reservoir to hold the therapeutic fluid; at least one other unit requiring communication with ambient air, at least partly, to operate; a reusable part housing including at least a portion of a driving mechanism and electronic components having a processor; at least one vent port formed on one or more walls of at least one of the disposable part housing and the reusable part housing; and a semi-permeable membrane covering the at least one vent port, the membrane being impervious to at least one liquid but pervious to at least one gas, wherein the at least one vent port is configured for communicating air into at least one of the disposable part housing and the reusable part housing to at least one of:
maintain pressure equilibrium between the air pressure therein and the ambient air pressure there out, andprovide communication with the ambient air to the at least one other unit requiring air to enable operation of the at least one other unit, wherein the at least one other unit includes a sensor to determine a body analyte level and wherein the at least one vent port is configured for providing air to the sensor to enable its operation.
