1. A device comprising:
- a. a body comprising a proximal end, a distal end, an outer surface, and a lumen defined within the body;
b. a base attached to the distal end of the body, the base comprising an outer face, an inner face, a plurality of apertures, at least one sensing area, and a network of passages in communication with the plurality of apertures and the at least one sensing area;
c. a plunger comprising;
i. a proximal end; and
ii. a distal end comprising a face;
iii. wherein the distal end of the plunger is configured to be disposed within the lumen at the proximal end of the body and the plunger is configured to be user-actuated within the lumen from the proximal end of the body to the distal end of the body; and
d. a plurality of needles fixed to the face of the plunger, wherein at least a portion of each of the plurality of needles is configured to extend through the plurality of apertures of the base and beyond the outer face of the base when the plunger is actuated to the distal end of the body;
e. wherein;
i. at least one of the plurality of needles is configured to pass through the plurality of apertures of the base and penetrate a subject'"'"'s skin to release bodily fluid; and
ii. the network of passages of the base is configured to collect at least some of the bodily fluid and communicate the bodily fluid to the at least one sensing area.

Abstract
A handheld device for drawing, collecting, and analyzing bodily fluid includes a body having a lumen defined therein, a plunger configured to be user-actuated, and a base. Multiple needles are fixed to the plunger, and at least one of the needles is configured to pass through the apertures of the base and penetrate a subject'"'"'s skin to release bodily fluid when the plunger is actuated. After the plunger is actuated, a mechanism retracts the plunger from the subject'"'"'s skin and creates a vacuum within the lumen. A network of passages on the base is configured to collect at least some of the bodily fluid and communicate the bodily fluid to one or more sensing areas for analysis.

15. A method comprising:
-
a. providing a handheld device for drawing, collecting, and analyzing bodily fluid, the device comprising; i. a body comprising a proximal end, a distal end, an outer surface, and a lumen defined within the body; ii. a base attached to the distal end of the body, the base comprising an outer face, an inner face, a plurality of apertures, at least one sensing area, and a network of passages in communication with the plurality of apertures and the at least one sensing area; iii. a plunger comprising; 1. a proximal end; and 2. a distal end comprising a face; 3. wherein the distal end of the plunger is configured to be disposed within the lumen of the body and the plunger is configured to move between the proximal end of the body and the distal end of the body; and iv. a plurality of needles fixed to the face of the plunger, wherein at least a portion of each of the plurality of needles is configured to extend through the plurality of apertures of the base and beyond the outer face of the base when the plunger is actuated to the distal end of the body; v. wherein; 1. at least one of the plurality of needles is configured to pass through the plurality of apertures of the base and penetrate a subject'"'"'s skin to release bodily fluid; and 2. the network of passages of the base is configured to collect at least some of the bodily fluid and communicate the bodily fluid to the at least one sensing area; b. placing the outer face of the base on a subject'"'"'s skin; c. manually actuating the plunger within the lumen toward the distal end of the body to cause the plurality of needles to pass through the plurality of apertures of the base and at least one of the plurality of needles to penetrate the subject'"'"'s skin; d. retracting the plunger from the distal end of the body to the proximal end of the body, thereby causing a vacuum to form in the lumen and drawing bodily fluid from the subject'"'"'s skin into the network of passages of the base; and e. directing the bodily fluid through the network of passages of the base to the at least one sensing area for analysis. - View Dependent Claims (22, 23)
