Disposable wearable insulin dispensing device, a combination of such a device and a programming controller and a method of controlling the operation of such a device
First Claim
1. A disposable pump device for dispensing insulin, comprising:
- a wearable pump housing that defines a space to receive a separate container;
an insulin container that is insertable into the space defined by the wearable pump housing, the insulin container having a perforatable dispensing end through which insulin is to be dispensed;
a piston rod comprising screw threads on an outer surface portion, the piston rod being movably arranged in the wearable pump housing to dispense the insulin from the insulin container when the insulin container is inserted in the wearable pump housing;
a drive system to advance the piston rod toward the insulin container and thereby dispense the insulin when the insulin container is inserted in the wearable pump housing; and
a battery to supply electrical power for operation of the disposable pump device, the battery being positioned inside the wearable pump housing,wherein the entire pump device is disposable and non-reusable.

Abstract
A disposable, wearable, self-contained insulin dispensing device includes a housing and an insulin source in the housing that is connected to a catheter for injecting insulin into a user. The catheter projects generally perpendicularly to a generally planar surface of the housing configured for abutting a skin surface of the user; which planar surface includes an adhesive layer for adhering the housing surface to the skin surface. A removable release sheet covers the adhesive layer for protecting the adhesive layer prior to use of the device. The release sheet is provided with a catheter protection element to enclose and protect an end portion of the catheter, such that removal of the release sheet for exposing the adhesive layer also exposes the end portion. A pump in the housing includes an actuator employing a shape memory alloy wire.
