Mobile infusion device
First Claim
1. A mobile infusion device that does not use gravity to expel fluid from a bag, wherein the mobile infusion device comprises:
- a housing including a first portion shaped to define a central chamber in the housing and a second portion shaped to define a first opening in the housing that is in communication with the central chamber and adapted to receive a portion of the bag during use;
a rotation assembly mounted at a fixed location in the housing, the rotation assembly including a first member and a second member mounted in opposition to one another located within the central chamber and a spring mechanism operatively coupled to the first member to rotate the first member in order to move the bag between the first and second members thereby applying a force to a portion of the bag to expel fluid from the bag during use; and
a control mechanism operatively coupled to the rotation assembly, the control mechanism having a control assembly to control rotation of the rotation assembly and a user interface coupled to the control assembly to allow a user to select one of a start mode, and a stop mode for the mobile infusion device during use,wherein the opening, the central chamber and the first and second members have a length that is long enough to accommodate bags of various sizes.

Abstract
Various embodiments are described herein for a mobile infusion device that does not use gravity to expel fluid from a bag. The device has a housing with a central chamber connected with an opening to receive a portion of the bag during use. A rotation assembly is coupled to the housing and includes at least one roller located within the central chamber and a spring mechanism operatively coupled to the at least one roller to rotate it to move the bag and apply a force to a portion of the bag to expel fluid therefrom during use. A control mechanism is operatively coupled to the rotation assembly and has a control assembly to control rotation of the rotation assembly and a user interface coupled to the control assembly to allow a user to select a mode of operation for the device. The spring mechanism is recharged in standby mode. Various mechanisms can be used in various embodiments to improve functionality such as a gearing mechanism.
