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 compressible reservoir located in the first housing portion, the reservoir having an interior volume for containing a fluid, the reservoir having an outlet connectable in fluid flow communication with an injection site, the interior volume of the reservoir being compressible to reduce the interior volume and increase fluid pressure within the interior volume to drive fluid from the interior volume to the injection site;
a compression mechanism operable on the reservoira drive device supported by the second housing portion and operatively connectable to at least one of the reservoir and the compression mechanism when the first and second housing portions are engaged, to selectively cause relative movement between the reservoir and compression mechanism for selective compression of the reservoir.

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.

11. A method of making a delivery device, 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; supporting a compressible reservoir on the first housing portion, the reservoir having an interior volume for containing a fluid and an outlet connectable in fluid flow communication with an injection site, the reservoir being compressible to reduce the interior volume and increase fluid pressure within the interior volume to drive fluid from the interior volume to the injection site; supporting a compression mechanism in a position to selectively compress the reservoir; supporting a drive device supported on the second housing portion in a position to operatively connect to at least one of the reservoir and the compression mechanism when the first and second housing portions are engaged, to selectively cause relative movement between the reservoir and compression mechanism for selective compression of the reservoir. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
