Abstract
Within examples, an apparatus for eliciting a blood sample includes a testing member rotatably mounted on a shaft; and an aperture for positioning a body part of the user relative to the edge of the testing member, wherein an edge of the testing member is shaped such as repeatedly to exert pressure on the skin of a user when the testing member is rotated.
Claims14
An apparatus for eliciting a blood sample, the apparatus comprising:
- a test disc member releasably mounted on a rotatable shaft, the test disc member having an outer edge, the outer edge including a first portion having a generally circular outer circumference and a second cutaway portion, wherein the cutaway portion comprises a plurality of ridges configured to collect blood from a user;
- an aperture;
- and
- a lancet attached to the test disc member and protruding from the cutaway portion of the outer edge of the test disc member, the lancet and the test disc member being configured such that the lancet pierces skin of the user's body part that is adjacent to the aperture as the test disc member is rotated in a first direction;
- wherein the test disc member is configured to collect blood from the user via the plurality of ridges when rotated in a second direction that is opposite the first direction after the skin of the user's body part is pierced;
- and
- wherein the apparatus is configured to rotate the test disc member via rotation of the shaft in the first direction to cause the lancet to pierce the skin of the user's body part that is adjacent to the aperture and configured to rotate the test disc member via rotation of the shaft in the second direction to collect blood from the user via the plurality of ridges.

A method for eliciting a blood sample, the method comprising:
- providing a test disc member releasably mounted on a rotatable shaft, the test disc member having an outer edge, the outer edge including a first portion having a generally circular outer circumference and a second cutaway portion, wherein the cutaway portion comprises a plurality of ridges;
- providing an aperture;
- providing a lancet protruding from the cutaway portion of the outer edge of the test disc member,
- rotating the test disc member in a first direction so that the lancet pierces skin of a user's body part that is adjacent to the aperture;
- and
- subsequent to rotating the test disc member in the first direction, rotating the test disc member in a second direction that is opposite the first direction, thereby collecting blood from the user via the plurality of ridges.
