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 coupled to the housing, the rotation assembly including at least one roller located within the central chamber and a spring mechanism operatively coupled to the at least one roller to rotate the at least one roller in order to move the bag and apply 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, a stop mode and a standby mode for the mobile infusion device during use,wherein the opening, the central chamber and the at least one roller have a length that is long enough to accommodate any size bag and in the standby mode the spring mechanism is recharged for future use.

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.

27. 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 coupled to the housing, the rotation assembly including at least one roller located within the central chamber, a drive member operatively coupled to the at least one roller, and a drive spring operatively coupled to the drive member, the drive spring and the drive member being configured to rotate the at least one roller in order to move the bag and apply 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 that can be actuated between an unlocked position and a locked position and a user interface for allowing a user to control the actuation of the control assembly, the control assembly allowing the drive member and the at least one roller to rotate or the drive spring to be recharged when the control assembly is in the unlocked position and the control assembly preventing rotation of the drive member and the at least one roller or recharging of the drive spring when the control assembly is in the locked position, wherein the opening, the central chamber and the at least one roller have a length that is long enough to accommodate bags of various sizes.
