SYSTEMS AND INTERFACES FOR BLOOD SAMPLING
First Claim
1. A device for receiving blood or other fluids from a subject, the device comprising:
- a flexible concave member moveable between a first configuration and a second configuration;
a needle mechanically coupled to the flexible concave member such that the needle is in a first position when the flexible concave member is in the first configuration and the needle is in a second position when the flexible concave member is in the second configuration;
an applicator region containing the needle at least when the needle is in the second position; and
a vacuum chamber having a pressure less than atmospheric pressure, wherein movement of the flexible concave member from the first configuration to the second configuration creates a fluid communication pathway between the vacuum chamber and the applicator region.

Abstract
The present invention generally relates to systems and methods for delivering and/or receiving a substance or substances such as blood from subjects. In one aspect, the present invention is directed to devices and methods for receiving or extracting blood from a subject, e.g., from the skin and/or from beneath the skin, using devices containing a substance transfer component (for example, one or more needles or microneedles) and a reduced pressure or vacuum chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In some embodiments, the device may contain a “snap dome” or other deformable structure, which may be used, at least in part, to urge or move needles or other suitable substance transfer components into the skin of a subject. In some cases, for example, the device may contain a flexible concave member and a needle mechanically coupled to the flexible concave member.

89. A device for receiving blood or other fluids from a subject, the device comprising:
-
a flexible concave member moveable between a first configuration and a second configuration; an actuator able to move the flexible concave member between the first configuration and the second configuration when actuated; a needle mechanically coupled to the flexible concave member such that the needle is in a first position when the flexible concave member is in the first configuration and the needle is in a second position when the flexible concave member is in the second configuration; an applicator region containing the needle at least when the needle is in the second position; and a vacuum chamber having a pressure less than atmospheric pressure, wherein the actuator, when actuated, is able to create a fluid communication pathway between the vacuum chamber and the applicator region. - View Dependent Claims (95, 99, 100, 103)
