Abstract

The disclosure relates to a skin piercing tool for locally puncturing a human or an animal skin, comprising a piercing needle, which is embodied as solid needle, in the case of which a needle body has a proximal needle section and a distal needle section, in which a piercing tip is arranged, wherein the needle body has a needle section, which is resilient against the piercing tip in response to a compressive stress, wherein the resilient needle section is arranged on the needle body in the area of an angled needle section, in which adjacent needle sections assume an angle of less than 180 with one another. Further, a hand-held device for repeated local puncturing of a human or an animal skin is provided.

Claims

1. A skin piercing tool for locally puncturing a human or an animal skin, comprising a piercing needle, which is embodied as solid needle, wherein a needle body of the piercing needle has needle sections including at least a proximal needle section and a at least a distal needle section, in which a piercing tip is arranged, wherein the body of the piercing needle has at least two resilient sections, each resilient section having a bend and being flexible and resilient in response to a compressive stress against the piercing tip, the bend of at least one of the at least two resilient sections being oriented in a different direction from the bend of at least one of the other at least two resilient sections, wherein the proximal needle section and at least one of the at least two resilient sections assume an angle of less than 180 degrees with respect to each other, and additionally comprising at least one further piercing needle, which forms a piercing needle group with the piercing needle.

2. The skin piercing tool according to claim 1, characterized in that the at least two resilient sections are arranged on the body of the piercing needle between the proximal needle section and the distal needle section.

3. The skin piercing tool according to claim 1, characterized in that the distal needle section is placed at an incline to a longitudinal direction of the body of the piercing needle.

4. The skin piercing tool according to claim 1, characterized in that one of the at least two resilient sections adjoining the distal needle section is placed at an incline to a longitudinal direction of the body of the piercing needle.

5. The skin piercing tool according to claim 1, characterized in that needle sections adjacent to the at least two resilient needle sections are adapted to carry out a folding or pivoting movement due to the resilience of the at least two resilient sections.

6. The skin piercing tool according to claim 1, characterized in that the at least two resilient needle sections are formed with at least one of a thinner material and a thicker material than either needle section adjacent thereto.

7. The skin piercing tool according to claim 1, characterized in that the at least two resilient sections of the piercing needle and at least two resilient sections of the at least one further piercing needle are arranged so as to be located next to one another.

8. The skin piercing tool according to claim 1, characterized in that the at least two resilient sections of the piercing needle and at least two resilient sections of the at least one further piercing needle are arranged so as to be offset relative to one another in a longitudinal direction of the piercing needle group.

9. The skin piercing tool according to claim 1, characterized in that the piercing needle and the further piercing needle are arranged so as to be located next to one another in a plane.

Description

DESCRIPTION OF EXEMPLARY EMBODIMENTS

(1) Further exemplary embodiments will be explained below with reference to figures of a drawing.

(2) FIG. 1 shows a schematic illustration of a piercing needle comprising a pronounced curved needle section,

(3) FIG. 2 shows schematic illustrations of piercing needles comprising an angled needle section,

(4) FIG. 3 shows schematic illustrations of piercing needles comprising a loop needle section,

(5) FIG. 4 shows a schematic illustration relating to the mode of operation of an embodiment of a piercing needle,

(6) FIG. 5 shows a schematic illustration relating to the mode of operation of a further embodiment of a piercing needle,

(7) FIG. 6 shows schematic illustrations of piercing needle groups comprising piercing needles with curved needle section,

(8) FIG. 7 shows schematic illustrations of piercing needle groups comprising piercing needles with angled needle section,

(9) FIG. 8 shows a perspective illustration of a piercing needle group,

(10) FIG. 9 shows a perspective illustration of a different piercing needle group, and

(11) FIG. 10 shows a schematic illustration of a hand-held device for repeatedly puncturing a skin.

(12) FIGS. 1 to 3 show embodiments for a single piercing needle 1, wherein provision is made on the needle body 2 for a resilient needle section 3. FIG. 1 shows an embodiment, in the case of which the needle body 2 has a curved needle section 4.

(13) The different embodiments (see also FIGS. 2 and 3 are provided with one or a plurality of angled areas 5, to which adjacent straight needle sections 5a, 5b connect. In the alternative, one or a both adjacent sections adjacent to the angled area can be curved. In the case of the straight sections, the latter assume an angle of less than 180. If one or two adjacent sections are curved, the straight section and the tangent to the curved section or the tangents to the two curved sections, which start at the angled section, assume an angle of less than 180.

(14) FIG. 3 shows embodiments, in the case of which a loop needle section 6 forms a resilient needle section on the needle body 3. As an alternative to the shown embodiment, the position of the loop needle section 6 can be interchanged with angled area 5.

(15) On the needle body 2, the individual piercing needles 1 have a proximal and a distal needle section 2a, 2b, wherein a piercing tip 2c is arranged on the distal needle section. The proximal needle section 2a can be formed as needle shaft, which can be used to fasten the piercing needle 1 to a hand-held device for locally puncturing a skin.

(16) FIG. 1 shows a longitudinal direction of the needle body 2 in a schematic manner by means of a dashed line A.

(17) In the case of the different embodiments, at least one further resilient needle section 7, 8 can be formed. In the alternative, the piercing needle 1 can also be embodied so as to be substantially non-resilient in this needle section, so that a resilience occurs only in the region of the resilient needle section 3 when pressure is applied to the piercing tip 1c.

(18) When using the piercing needle 1, the provision of the resilient needle section or sections 3, 5, 7, 8 leads to the tilting or pivoting of at least the distal needle section 2b, when pressure is applied to the piercing tip 1c in response to puncturing the skin. This is shown schematically in FIGS. 4 and 5. The substance introduction into a skin 11, for which a section is shown in cross section in FIGS. 4 and 5, can be improved in this manner.

(19) FIGS. 6 and 7 show schematic illustrations of piercing needle groups 9, in the case of which a plurality of the piercing needles 1 shown in FIGS. 1 to 3, which are arranged on a needle holder 10, form a skin piercing tool.

(20) FIGS. 8 and 9 in each case show a perspective illustration of a piercing needle group 9, in the case of which proximal needle sections 2a of a plurality of piercing needles are arranged next to one another in a plane. The shown embodiments of the piercing needle 1 are embodied as solid needle.

(21) FIG. 10 shows a schematic illustration of a hand-held device 20 for repeatedly puncturing a skin comprising a drive module 21, to which a needle module 22 couples functionally. A skin piercing tool 23 in one of the embodiments described herein is arranged on the needle module 22. The drive module can be connected to an electrical power supply via a cable 24, for example via a control device (not illustrated). Provision can also be made for a cable-free battery operation.

(22) The features disclosed in the description above, the claims as well as the drawing can be significant for the realization of the different embodiments, both alone as well as in any combination.
