Penetration device, kit, and method
First Claim
1. A method for extracting body fluid from a body part, the method comprising the steps of:
- providing a penetration device including a penetration element formed to pierce the body part and an actuator formed to propel forward movement of the penetration element, moving the penetration element toward the body part at a very high penetration speed to form an impression in the body part having a depth less than about 0.3 mm, and piercing the body part with the penetration element.

Abstract
The present invention provides a method and device for extracting body fluid from a body part. The method provides a penetration device including a penetration element formed to pierce the body part and an actuator formed to propel forward movement of the penetration element. The penetration element is moved toward the body part at a very high penetration speed to form an impression in the body part having a depth less than about 0.3 mm and the body part is pierced with the penetration element. The actuator of the penetration device is formed to propel forward movement of the penetration element at a penetration speed of at least about 15 m/sec.

18. A penetration device for the extraction of a body fluid, the device comprising:
a penetration element formed to pierce a skin of a body part, and actuating means for propelling a penetration movement of the penetration element, wherein the actuating means has a high-speed drive formed to bring the penetration element to such a high penetration speed that a penetration depth variation caused by skin impression is less than about 0.3 mm. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A penetration kit for the extraction of body fluid from a body part, the kit comprising:
-
a pressing ring, a penetration element sized for extension into the pressing ring and formed to pierce the body part, a first actuator formed to propel forward movement of the penetration element at a penetration speed of at least about 15 m/sec, and a second actuator formed to propel a retraction of the penetration element from the body part. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
