Abstract

Claims (27)

1. A system comprising:

a dermal patch comprising a housing configured to attach to a subject's skin,

wherein the housing includes an opening to provide access to the subject's skin when the dermal patch is attached to the subject's skin, and

a lancet separate from the dermal patch and configured for insertion into and withdrawal from the dermal patch, and configured to engage with the opening,

wherein the lancet includes a needle movable from an undeployed position to a deployed position,

wherein in the deployed position, the needle is capable of puncturing the subject's skin to draw a physiological sample.

2. The system of claim 1 , wherein the lancet is configured to retain the needle within the lancet when the needle is in the undeployed position.

3. The system of claim 2 , wherein the lancet includes a first spring and a second spring.

4. The system of claim 3 , wherein when the needle is in the undeployed position the first spring is in a compressed state and the second spring is in an extended state.

5. The system of claim 3 , wherein when the needle is in the deployed position the first spring is in an extended state and the second spring is in a compressed state.

6. The system of claim 1 , wherein the lancet further includes a needle platform that supports the needle.

7. The system of claim 1 , wherein the housing further includes:

a chamber, and

an absorbent element disposed within the chamber,

wherein the absorbent element is configured to store the drawn physiological sample.

8. The system of claim 1 , further comprising:

a fluid pouch coupled to the housing,

wherein the fluid pouch is configured to store a processing fluid.

9. The system of claim 8 , wherein the fluid pouch is formed of a frangible membrane.

10. The system of claim 1 , further comprising:

a moveable pin disposed within the housing,

wherein the pin is configured to generate a vacuum within the housing when moved, and

wherein the vacuum generated by the pin is proportional to the movement of the pin.

11. The system of claim 1 , wherein the physiological sample includes blood or interstitial fluid.

12. The system of claim 1 , wherein the housing further includes:

an adhesive film disposed on a bottom surface of the housing,

wherein the adhesive film is configured to attach the housing to the skin of the subject.
