Abstract

Improved systems and methods for medicine delivery, and in particular, improved insulin pen needles and related devices are provided. Smart injection devices record and transfer data including medicine level, delivered dose, dose confirmation, and dose time and date. Additional data captured may include glucose concentration, insulin level, carbohydrates ingested, stress level, exercise, blood pressure, and glucose high and low excursion events. Various means of data collection and analysis are provided and systems can identify and flag patients who require intervention. Smart sleeves and add sensing capability to standard insulin pens. Pen needles are provided with sensing capability to confirm and measure doses delivered by insulin pen. A two-part pen cap include a primary sleeve that connects to the insulin pen and an end cap that provides for capturing the time of dose delivery, and monitoring the hold time for a dose delivery after plunger movement.

First claim

What is claimed is:

1. A device for measuring delivered dose information comprising:
an insulin delivery device having a proximal end and a distal end, a plunger and an insulin vial comprising insulin distal of said plunger;
a two-part pen cap, comprising:
a sleeve enclosing the insulin delivery device, lockable onto the insulin delivery device and comprising at least one light emitter and a plurality of light sensors, wherein the at least one light emitter is oriented to project light through insulin in the insulin vial to the light sensors;
a second portion attaching to the sleeve and enclosing the distal end of the insulin delivery device; and
a locking hub for locking the sleeve to the insulin delivery device;
wherein the second portion is adapted to reveal the distal end of the insulin delivery device while the first sleeve remains on the insulin delivery device during an injection;
wherein the at least one light emitter is positioned on the sleeve to project light through insulin in the insulin vial during the injection and the plurality of light sensors are positioned to receive light projected through insulin in the insulin vial to measure a dose delivered during the injection; and
wherein the sleeve is programmed to detect when the plunger stops and to provide a signal indicating a successful dose after a predetermined period elapses after the plunger stops during which a skin detector detects contact of the insulin delivery device with skin.

2. The device of claim 1 , wherein the second portion is detachably connected to the sleeve.

3. The device of claim 1 , wherein the second portion is permanently connected to the sleeve and hinged to move from a first configuration in which the distal end of the insulin delivery device is enclosed to a second configuration in which the distal end of the insulin delivery device is exposed.
