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, wearable, self-contained insulin dispensing device comprising:
- a housing, an insulin source in said housing, a pump means in said housing and adapted for pumping insulin from said insulin source to a catheter for injection of said insulin in a user of the device, said catheter being associated with said housing and projecting generally perpendicularly to a generally planar surface of said housing intended for abutting a skin surface of a user of the device, an adhesive layer provided on said planar surface for adhering said planar surface to said skin surface, and a removable release sheet covering said adhesive layer for protecting said adhesive layer prior to use of said dispensing device, said release sheet being provided with catheter protection means to enclose and protect an end portion of said catheter such that removal of said release sheet for exposing said adhesive layer exposes said end portion.

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.
