Abstract

Exemplary embodiments may provide an adhesive pad that is designed to be used with an on-body medical device. The adhesive pad may partially or fully surround a perimeter of the on-body medical device. The adhesive pad may be the primary mechanism or may provide an additional mechanism for helping to secure the on-body medical device to the user. In addition, the adhesive pad may include a metallic coil, such as a metal loop, that is woven into the adhesive pad or otherwise inserted into or secured to the adhesive pad. The metallic coil may play multiple roles. First, the metallic coil may act as an antenna to facilitate wireless communications with the on-body medical device, such as NFC communications. In addition, the metallic coil may serve as a power source for electric components positioned on the adhesive pad.

First claim

The invention claimed is:

1. A system, comprising:
an on-body medical device having a first metallic coil; and
an adhesive pad for use with an on-body medical device, comprising:
a geometry configured to at least partially surround the on-body medical device,
an adhesive on one side of the adhesive pad for securing the adhesive pad to skin of a user, and
a second metallic coil secured to or positioned within the adhesive pad for acting as an antenna for wireless communications to and from the on-body medical device, wherein the first metallic coil and the second metallic coil are positioned and configured so that applying power to either of the metallic coils causes a magnetic field to be generated that causes a current to be generated in the other of the metallic coils to facilitate the wireless communications; and
an electronic component secured to the adhesive pad and electrically connected to the second metallic coil so that the second first metallic coil powers the electronic component.

2. The system of claim 1 , wherein the electronic component is a sensor for sensing a biometric of the user.

3. The system of claim 2 , further comprising at least one additional sensor electrically coupled to the second metallic coil.

4. The system of claim 2 , wherein the sensor measures at least one of activity, heart rate, moisture, temperature, glucose, analytes or sound pressure.

5. The system of claim 1 , wherein the electronic component is a system on a chip (SoC).

6. The system of claim 1 , wherein the electronic component is a wireless communications component.

7. The system of claim 1 , wherein the on-body medical device is an insulin pump.

8. The system of claim 1 , wherein the second metallic coil of the adhesive pad and the first metallic coil of the on-body medical device communicate via Near Field Communication (NFC).

9. The system of claim 1 , wherein the adhesive pad is configured to be secured to a skin of the user and overlap with a portion of the on-body medical device to help secure the on-body medical device to the user.

10. A method, comprising:
including a first metallic coil in an on-body medical device;
including a second metallic coil in an adhesive pad in proximity to the on-body medical device;
securing an electronic component to the adhesive pad;
configuring the second metallic coil in the adhesive pad as an antenna for wireless communications to and from the on-body medical device, wherein the first metallic coil and the second metallic coil are positioned and configured so that applying power to either of the metallic coils causes a magnetic field to be generated that causes a current to be generated in the other of the metallic coils to facilitate the wireless communications; and
electronically connecting the electronic component to the second metallic coil to provide power to the electronic component.

11. The method of claim 10 , wherein the on-body medical device is an insulin pump.
