Infusion medium delivery device and method with compressible or curved reservoir or conduit
First Claim
Patent Images
1. A delivery device comprising:
- a first housing portion;
a second housing portion configured to selectively engage with and disengage from the first housing portion;
a reservoir located in the first housing portion, the reservoir having a first interior volume for containing a fluid, the reservoir having an outlet connectable in fluid flow communication with the first interior volume and an injection site, the first interior volume of the reservoir being selectively variable;
a volume varying mechanism defining a boarder of the first interior volume and supported for motion in a curved path to selectively vary the first interior volume of the reservoir, to selectively reduce the first interior volume and increase fluid pressure within the interior volume to drive fluid from the interior volume to the injection site; and
a drive device supported by the second housing portion and operatively connectable to the volume varying mechanism when the first and second housing portions are engaged, to selectively drive the volume varying mechanism in the curved path of motion.

Abstract
A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient-user and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient-user or with infusion media are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports other components such as electronics for controlling delivery of infusion media from the reservoir and a drive device and drive linkage.

15. A method of making a delivery device for delivering a fluidic medium to or from a patient, the method comprising:
-
providing a first housing portion; providing a second housing portion configured to selectively engage with and disengage from the first housing portion; providing a reservoir in the first housing portion, the reservoir having a first interior volume for containing a fluid, the reservoir having an outlet connectable in fluid flow communication with the first interior volume and an injection site, the first interior volume of the reservoir being selectively variable; supporting a volume varying mechanism adjacent a boarder of the first interior volume for motion in a curved path to selectively vary the first interior volume of the reservoir, to selectively reduce the first interior volume and increase fluid pressure within the interior volume to drive fluid from the interior volume to the injection site; and supporting a drive device on the second housing portion in a position to operatively connect to the volume varying mechanism when the first and second housing portions are engaged, to selectively drive the volume varying mechanism in the curved path of motion. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
