Automated blood sampling device
First Claim
1. A system comprising:
- a needle, wherein the needle is configured to penetrate skin;
an injector, wherein the injector is configured to drive the needle into the skin to form a puncture in the skin and subsequently to retract the needle from the skin;
a suction source configured to provide suction; and
a seal, wherein the seal is configured to receive suction provided by the suction source, wherein the injector is configured to drive the needle through the seal to form at least one hole in the seal, and wherein the suction provided by the suction source is configured to draw blood from the formed puncture in the skin through the formed at least one hole in the seal.

Abstract
Devices are provided to automatically access blood from beneath or within skin. These devices include an injector configured to drive a needle into the skin and subsequently to retract the needle from the skin. These devices additionally include a seal to which suction is applied. To drive the needle into the skin, the needle is first driven through the seal, creating at least one hole in the seal. The suction applied to the seal acts to draw blood from the puncture formed in the skin by the needle, through the at least one hole in the seal, and to a sensor, blood storage element, or other payload. These devices can be wearable and configured to automatically access blood from skin, for example, to access blood from the skin at one or more points in time while a wearer of a device is sleeping.

14. A method comprising:
-
mounting a system to skin, wherein the system comprises; a needle, wherein the needle is configured to penetrate the skin, an injector, a suction source configured to provide suction, and a seal, wherein the seal is configured to receive suction provided by the suction source; and operating the injector to drive the needle into the skin to form a puncture in the skin and subsequently to retract the needle from the skin, wherein operating the injector to drive the needle into the skin further comprises driving the needle through the seal to form at least one hole in the seal, and wherein the suction provided by the suction source is configured to draw blood from the formed puncture in the skin through the formed at least one hole in the seal. - View Dependent Claims (15, 16, 17)
