Abstract

A bleeding apparatus includes a first stimulating component for pressing an examinee at a first simulating point so as to induce sense perception, and a second stimulating component for pressing the examinee at a second simulating point so as to induce sense perception. A distance between the first stimulating component and the second stimulating component is less than or equal to a two-point sense threshold of a human perception system. The bleeding apparatus further includes a bleeding component disposed between the first stimulating component and the second stimulating component for bleeding the examinee between the first stimulating point and the second stimulating point when the first stimulating component is pressing the examinee at the first simulating point and the second stimulating component is pressing the examinee at the second simulating point.

Claims

1. A bleeding apparatus comprising:

a first stimulating component for pressing a first simulating point of an examinee;

a second stimulating component for pressing a second simulating point of the examinee; and

a bleeding component disposed between the first and second stimulating components for bleeding the examinee,

wherein a distance between the first and second simulating points is less than or equal to a two-point sense threshold of the examinee.

2. The bleeding apparatus of claim 1, wherein the bleeding component is a needle.

3. The bleeding apparatus of claim 1, wherein the distance between the first and second simulating points is depended on a human part where the bleeding apparatus bleeds.

4. The bleeding apparatus of claim 1, wherein an end of the first stimulating component or the second stimulating component for pressing is a blunt head.

5. The bleeding apparatus of claim 1, wherein a height of the bleeding component is less than those of the first and second stimulating components.

6. The bleeding apparatus of claim 1, wherein the first and second stimulating components constitute a stimulating component array.

7. The bleeding apparatus of claim 4, wherein the stimulating component array is circular.

8. The bleeding apparatus of claim 7, wherein the bleeding component is disposed in the center of the stimulating component array.

9. The bleeding apparatus of claim 7, wherein the bleeding component is disposed on the rim of the stimulating component array.

10. The bleeding apparatus of claim 7, wherein a diameter of the stimulating component array is 15 mm.

11. The bleeding apparatus of claim 1, further comprising a rod-type structure, and the first stimulating component, the second stimulating component, and the bleeding component are disposed at an end of the rod-type structure.

12. The bleeding apparatus of claim 11, wherein the bleeding component is disposed in a body in an extendable manner.

13. The bleeding apparatus of claim 12, wherein the bleeding component is capable of protruding out of the body when turning on a switch on the body.

14. The bleeding apparatus of claim 12, wherein the first and second stimulating components are disposed on an attachment capable to be attached to the end of the rod-type structure.

15. The bleeding apparatus of claim 1, wherein the two-point sense threshold is 2 mm.

16. The bleeding apparatus of claim 1, wherein the two-point sense threshold is 3 mm.

17. The bleeding apparatus of claim 1 wherein the two-point sense threshold is 13 mm.

18. The bleeding apparatus of claim 1 wherein the two-point sense threshold is 48 mm.
