US 10,092,691 B2 · Flexible and conformal patch pump

Abstract

Provided is a flexible and conformal wearable, self-contained medical device. The medical device comprises an integral housing formed by a flexible upper portion and a flexible lower portion joined along their perimeters. The medical device is also provided in a plurality of shapes and configurations for increasing the flexibility and conformability of the housing. The components contained within the housing, such as a drug reservoir, printed circuit board, and power supply are preferably constructed from flexible materials and are formed, connected and positioned according to the configuration of the housing in a manner for enhancing flexibility of the housing. A thermal bubble micropump is provided for controlling flow of a drug from the flexible reservoir, that utilizes a thermal resistor provided locally to a thermal expansion fluid that causes a surrounding membrane to expand and displace a volume of drug to be provided to the user.
