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.
Claims20
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 patch pump comprising a pump housing;
- a pump motor disposed within the pump housing and configured to pump the medication in the cartridge towards the transcutaneous portion;
- a sensor configured to detect the wearer's skin and to generate information on whether there is a detection of the wearer's skin;
- and
- a controller operatively coupled to the pump motor and the sensor, the controller configured to cause the patch pump to act based on the information on whether there is the detection of the wearer's skin,
- wherein the controller is configured to act by causing the pump motor to activate to pump the medication in the cartridge towards the transcutaneous portion if the information indicates that the wearer's skin is detected.
A method of using a medication infusion device for delivering doses of medication from a cartridge through a transcutaneous portion, the method comprising:
- providing a patch pump configured to be removably adhered to a wearer's skin for delivering the doses of medication from the cartridge through the transcutaneous portion, the patch pump comprising a pump motor disposed within a pump housing, the pump motor configured to pump the medication in the cartridge towards the transcutaneous portion;
- sensing, using a sensor of the patch pump, whether the wearer's skin is detected;
- generating information based on whether there is detection of the wearer's skin;
- and
- causing the patch pump to act based on the information on whether there is the detection of the wearer's skin, including causing the pump motor to activate to pump the medication in the cartridge towards the transcutaneous portion if the information indicates that the wearer's skin is detected.
