INSTRUMENT FOR REINFORCING MUSCLE STRENGTH TO BEND FROM NAIL TIP TO SECOND JOINT IN ORDER TO SIMULATE ACUPRESSURE POINT OF PALM AND/OR IN FOREFINGER, MIDDLE FINGER AND RING FINGER OF HAND

摘要

PROBLEM TO BE SOLVED: To provide an instrument for reinforcing muscle strength to bend from a nail tip to a second joint in order to stimulate the acupressure point of the palm and/or in a forefinger, a middle finger and a ring finger of a hand.SOLUTION: An instrument is integrally configured by an elastic material, and has a rear part 2 coming into contact with a palm, a side periphery 3 of a curved shape easy to grasp, and a front part 4 gripped by end-pieces of five fingers. Multiple pressing protrusions 8 are provided on the portion opposed to the palm in the rear part. Multiple protrusions 5, 6 and a groove 7 between the protrusions are formed in the front part. The instrument is configured as follows: the hardness of the elastic material is E35-E60; the protrusions are formed in the ratio of 5-6 pieces per 10 cm; all or a portion of the protrusions are corn form bodies that are 9-11 mm in diameter of a bottom face, have an apical angle of 80 degrees to 100 degrees and may have an apex being a curved surface; a length in the groove is 5-7 cm; a width is 0.5 cm to 1.5 cm; and the thickness of the elastic material in the bottom section of the groove is 1.5 cm to 2.5 cm.SELECTED DRAWING: Figure 1
