Abstract

Various embodiments of the present invention are directed to patches for medical devices. In various embodiments, an adhesive patch of a medical device may have selective areas with adhesive material of varying adhesion strengths. In other embodiments, an adhesive patch of a medical device may include adhesive material that may be activated by a catalyst to increase or decrease the adhesion strength of the adhesive material. In further embodiments, a medical device may include a pierceable membrane containing an agent, the pierceable membrane positioned to be pierced by a needle and to cause some of the agent to be carried to the user-patient.

3. The medical device according to claim 2,

the second region of the base remotely located from the first region of the base.

4. The medical device according to claim 3, wherein at least two of the plurality of regions of the base are each proximate to an edge of the base.

5. The medical device according to claim 3, the adhesive material having a greater adhesion strength on the first region of the base than on the second region of the base.

6. The medical device according to claim 3, each of the first region of the base and the second region of the base bordered entirely by the area of the base.

7. The medical device according to claim 2, the medical monitoring or treatment device including the at least one of the needle and the cannula for insertion into skin of the patient during operation of the medical monitoring or treatment device.

8. The medical device according to claim 2,

the plurality of regions of the base further comprising a third region;

the first region of the base having a length dimension extending in a first direction;

the second region of the base having a length dimension extending in a direction parallel with the first direction, the third region of the base having a length dimension extending in a direction parallel with the first direction;

wherein the second region of the base and the first region of the base are aligned in a second direction transverse the first direction;

wherein the second region of the base is arranged between the first region of the base and a first edge of the base;

wherein the first region of the base is arranged between the second region of the base and a second edge of the base; and

wherein the third region of the base is arranged between the second region of the base and the first region of the base and outside of the length dimension of the first region of the base and the length dimension of the second region of the base.

9. The medical device according to claim 8, wherein the second region of the base and the first region of the base are spaced from the first edge of the base and the second edge of the base.

10. The medical device according to claim 2,

the medical monitoring or treatment device for use with a cannula and a needle for insertion into the patient during the monitoring or treatment operation of the medical monitoring or treatment device;

wherein the cannula remains locked in an extended state after it is inserted into the patient and after the needle is retracted from the patient, during the monitoring or treatment operation of the medical monitoring or treatment device.

11. The medical device according to claim 1,

the medical monitoring or treatment device for use with at least one of a needle and a cannula for insertion into the patient during the monitoring or treatment operation of the medical monitoring or treatment device;

the base having an opening through which the at least one of the needle and the cannula extends during the monitoring or treatment operation of the medical monitoring or treatment device;

wherein the first region of the base at least partially surrounds the opening in the base.

12. The medical device according to claim 1,

the base adapted to be secured to skin of the patient;

wherein the adhesive material comprises a material that adheres to human skin.

13. The medical device according to claim 1, wherein a surface area of the area of the base is greater than a surface area of each of the plurality of regions of the base.
