Abstract

A skin perforating member for an insulin patch, which is for disposing a human skin before administering insulin transdermally. By a pressure sensing arrangement instailed on both sides of a skin perforating member, a user can learn whether scarring a skin is properly going on at the sight of a pilot lamp. When not used, this device deposits the skin perforating member in its main body to shield perforating needles.

Claims

1. A skin perforating apparatus, comprising:

a main body having a through groove formed on a top portion of said main body, stoppers protrusively formed on lower left and right portions inside said main body, sills formed on left and right lower end portions inside said main body, guide grooves formed between said stoppers and said sills, a recess portion formed inside said main body, and an apparatus for forming a plurality of punctures, said apparatus located in said recess portion when said apparatus is not in use;

a subbody being generally "I"-shaped and having an upper push head, a central stem, and a bottom base, said subbody being engaged with said main body with said through groove so that said push head is located outside of said main body and said bottom base is located within said main body;

traveling members located within said recess portion and respectively engaged with the bottom base of said subbody and said main body, and elastic members engaged with said traveling members, said traveling members thereby being located in said main body by a biasing force of said elastic members if no exterior force is applied thereto;

said elastic members biasing the traveling members to make said traveling members move elastically and vertically in the main body, said elastic members being interposed between said traveling members and the sills of said main body; and

said apparatus for forming the plurality of punctures further comprising a central shaft rotatably supported by said traveling members and having a plurality of skin perforating needles formed on a circumference of the apparatus,

said main body including an opening through which said needles project when said subbody is manually operated by a user depressing the push head against bias of said elastic members.

2. The apparatus according to claim 1, wherein said elastic members are coil springs.

3. The apparatus according to claim 1, wherein a traveling degree of said apparatus for forming a plurality of punctures is determined in accordance with a traveling degree of said subbody.

4. The apparatus according to claim 1, wherein said main body has a feature and size to such an extent that a user can grip and apply force to said subbody easily.

5. The apparatus according to claim 1, wherein said main body further comprises a cap which is assembled to a bottom of said main body to cover said opening.

6. A skin perforating apparatus, comprising:

a main body having a through groove formed on a top portion of said main body, stoppers protrusively formed on lower left and right portions inside said main body, sills formed on left and right lower end portions inside said main body, guide grooves formed between said stoppers and said sills, and a recess portion formed inside said main body, and an apparatus for forming a plurality of punctures, said apparatus located in said recess portion when said apparatus is not in use;

a subbody being generally "I"-shaped and having an upper push head, a central stem, and a bottom base, said subbody being engaged with said main body with said through groove so that said push head is located outside of said main body and said bottom base is located within said main body;

traveling members located within said recess portion and respectively engaged with the bottom base of said subbody and said main body, and elastic members engaged with said traveling members, said traveling members thereby being located in said main body by a biasing force of said elastic members if no exterior force is applied thereto;

said elastic members biasing the traveling members to make said traveling members move elastically and vertically in the main body, said elastic members being interposed between said traveling members and the sills of said main body; and

said apparatus for forming the plurality of punctures further comprising a central shaft rotatably supported by said traveling members and having a plurality of skin perforating needles formed on a circumference of the apparatus; and

means for sensing and displaying vertical movement of said subbody,

said main body including an opening through which said needles project when said subbody is manually operated by a user depressing the push head against bias of said elastic members.

7. The apparatus according to claim 6, further including upper elastic members secured to upper vertically projecting side portions of each traveling member, an elasticity of said upper elastic member is equal to that of said members elastic member.

8. The apparatus according to claim 6, further including upper elastic members secured to upper vertically projecting side portions of each traveling member, an elasticity of said upper elastic members are different from that of said members elastic member.

9. The apparatus according to claim 6, further including upper elastic members secured to upper vertically projecting side portions of each traveling member, an elasticity of said elastic members are stronger than that of said upper elastic members.

10. The apparatus according to claim 6, upper elastic members secured to upper vertically projecting side portions of each traveling member, said upper and elastic members are coil springs.

11. The apparatus according to claim 6, wherein a traveling degree of said apparatus for forming a plurality of punctures is determined in accordance with a traveling degree of said subbody.

12. The apparatus according to claim 6, wherein said main body has a feature a size to such an extent that a user can grip and apply force to said subbody easily.

13. The apparatus according to claim 6, wherein said main body further comprises a cap which is assembled to a bottom of said main body to cover said opening.
