Embodiment Construction

[0098] Figure 1a and Figure 1b It is a perspective view of a puncture device in an assembled state and a disassembled state according to Embodiment 1 of the present invention. The base (body) 1, 2, which consists of two halves, has an opening 3 provided on its underside, through which a needle holding element can be extended and retracted.

[0099] A connecting bolt 5 is provided on the lower half for releasing a latching element. As a manual actuation element, a button 4 is formed by a very thin wall inside the housing half, the planar position of which changes with externally acting pressure. The button can be arranged on only one housing half or both housing halves.

[0100] A needle holding element 6 , preferably in the shape of a flat strip, has a cam 7 on the surface of the needle holding element, and the cam 7 is used to engage with an arc-shaped groove 13 of a rotary element 12 .

[0101] A needle 8 with a distal end 9 is provided with a protective cap 10 at the f...

Abstract

The invention relates to a pricking device for taking blood for medical tests. Said pricking device comprises a base (1, 2; 31, 32; 61, 62), at least one needle (8; 38; 68) which is arranged therein,of which a pointed end (9; 39; 69) can be deployed, and which is provided with a needle retaining element (6; 36; 66) that at least partly embraces the needle (8; 38), and a manual actuating element (4; 34; 64) for inducing a movement (20; 21; 48-52; 78-82) of the needle (8; 38; 68) along with the needle retaining element (6; 36; 66) relative to the base (1, 2; 31, 32; 61, 62). The needle (8; 38;68) is spring-loaded. At least one leg spring (11; 41; 71) is provided, the first end (11b; 41b; 71b) of which is fastened to the base (2; 32; 62) and the second end (11a; 41a; 71a) of which allows the needle retaining element (6; 36; 66) to travel along a predefined curved control cam section (13; 43; 73) during a releasing process (19, 21; 49, 51; 79, 81) of the leg spring (11; 41; 71).

Description

technical field [0001] According to the preamble of claim 1, the present invention relates to a puncture device for blood collection for medical examination, which comprises a base (main body), at least one of which is arranged in the base and has an outwardly protruding The needle at the end, the device also has a needle-holding element at least partially surrounding the needle, and a manual drive element for driving the needle and the needle-holding element together to move relative to the base (body) , where the needle is spring loaded. Background technique [0002] Piercing devices designed in the manner of a lancet for piercing the epidermis for subsequent blood sampling are known in various forms. These piercing devices are often designed to be reusable, and thus sterile, and further, clinical practitioners are required to use such piercing devices in a substantially painless manner. [0003] DE19617000C1 discloses a device comprising a needle for blood collection, w...
