Abstract
Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.
Claims30
A medication infusion device comprising a patch pump configured to be removably adhered to a wearer's skin for delivering doses of medication from a cartridge through a transcutaneous portion, the medication infusion device comprising:
- a dosing tube configured to receive medication;
- a plurality of levers configured to contact the dosing tube to move a predetermined dose of medication towards the transcutaneous portion;
- a sensor configured to sense position of one or more of the plurality of levers;
- and
- a controller operatively coupled to the sensor, wherein the controller senses that the medication infusion device is not delivering medication if the sensor does not sense a predetermined displacement of the one or more of the plurality of levers.
A medication infusion device comprising a patch pump configured to be removably adhered to a wearer's skin for delivering doses of medication from a cartridge through a transcutaneous portion, the medication infusion device comprising:
- a dosing tube configured to receive medication;
- a plurality of levers configured to contact the dosing tube to move a predetermined dose of medication towards the transcutaneous portion;
- a sensor configured to sense position of one or more of the plurality of levers;
- a pump configured to house the sensor;
- a cap configured to house the plurality of levers;
- and
- a controller operatively coupled to the sensor, wherein the controller is configured to sense whether the pump is coupled to the cap based on the sensed position of the one or more of the plurality of levers.
A medication infusion device comprising a patch pump configured to be removably adhered to a wearer's skin for delivering doses of medication from a cartridge through a transcutaneous portion, the medication infusion device comprising:
- a dosing tube configured to receive medication;
- a plurality of levers configured to contact the dosing tube to move a predetermined dose of medication towards the transcutaneous portion;
- a cap;
- a sensor configured to sense position of one or more of the plurality of levers, the sensor further configured to sense a presence or absence of the cap;
- and
- a controller operatively coupled to the sensor.
A method for monitoring transcutaneous delivery of doses of medication, the method comprising:
- delivering doses of medication using a patch pump adhered to a wearer's skin, the patch pump comprising a dosing tube configured to receive the medication responsive to pumping, a plurality of levers configured to contact the dosing tube, and a transcutaneous portion fluidically coupled to the dosing tube;
- sensing displacement of one or more of the plurality of levers during the pumping;
- and
- determining that the dosing tube or the transcutaneous portion is occluded based on the sensed displacement of the one or more of the plurality of levers.
A method for monitoring transcutaneous delivery of doses of medication, the method comprising:
- delivering doses of medication using a patch pump adhered to a wearer's skin, the patch pump comprising a dosing tube configured to receive the medication responsive to pumping and a plurality of levers configured to contact the dosing tube;
- sensing displacement of one or more of the plurality of levers during the pumping;
- sensing that the patch pump is not delivering medication if the sensor does not sense a predetermined displacement of the one or more of the plurality of levers;
- and
- determining an infusion anomaly associated with medication delivery from the dosing tube has occurred based on the sensed displacement of the one or more of the plurality of levers.
A method for monitoring transcutaneous delivery of doses of medication, the method comprising:
- delivering doses of medication using a patch pump adhered to a wearer's skin, the patch pump comprising a dosing tube configured to receive the medication responsive to pumping, a plurality of levers configured to contact the dosing tube, a pump configured to house a sensor, and a cap configured to house the plurality of levers;
- sensing displacement of one or more of the plurality of levers during the pumping;
- sensing whether the pump is coupled to the cap based on the presence of a magnet and its position;
- and
- determining an infusion anomaly associated with medication delivery from the dosing tube has occurred based on the sensed displacement of the one or more of the plurality of levers.
A medication infusion device comprising a patch pump configured to be removably adhered to a wearer's skin for delivering doses of medication from a cartridge through a transcutaneous portion, the medication infusion device comprising:
- a dosing tube configured to receive medication;
- a plurality of levers configured to contact the dosing tube to move a predetermined dose of medication towards the transcutaneous portion;
- a sensor configured to sense position of one or more of the plurality of levers, wherein the sensor is further configured to sense displacement of one or more of the plurality of levers;
- and
- a controller operatively coupled to the sensor, the controller configured to sense an infusion anomaly associated with medication delivery from the dosing tube based on the sensed displacement from the sensor,
- wherein the dosing tube comprises a flattened portion configured to hold the predetermined dose of medication.
