Abstract

The application relates to portable medical devices that can be placed on a patient'"'"'s skin and that include a silicone-based adhesive for attaching the device to the skin removeably or releasably. In preferred embodiments, the adhesive is a silicone pressure-sensitive adhesive (PSA) or a silicone soft-skin adhesive (SSA).

Claims

1. A portable medical device for placement on the skin of a patient, the device comprising a silicone-based adhesive for releasably fixing the device on the skin.

2. The medical device according to claim 1, wherein the device is for the subcutaneous administration of a liquid medicine.

3. The medical device according to claim 2, wherein the device is a portable insulin pump.

4. The medical device according to claim 2, wherein the device is an infusion set for the subcutaneous administration of insulin.

5. The medical device according to claim 1, wherein the device comprises a sensor for measuring a physiological parameter.

6. The medical device according to claim 5, wherein the sensor is an electrochemical sensor for measuring a blood sugar value or an interstitial sugar content.

7. The medical device according to claim 1, wherein the adhesive is part of a plaster disposed on a surface of the medical device, said plaster for contacting the skin.

8. The medical device according to claim 7, wherein the surface is at least a portion of an underside of the device.

9. The medical device according to claim 8, wherein the surface is substantially flat.

10. The medical device according to claim 1, wherein the silicone-based adhesive is one of a silicone pressure-sensitive adhesive (PSA).

11. The medical device according to claim 1, wherein the silicone-based adhesive is a silicone soft skin adhesive (SSA).
