Deformed nail corrector

A kit for correcting a deformed nail including a pair of deformed nail correctors formed in a band shape and configured to be attached to both left and right sides of a nail, each of the deformed nail correctors comprising:

• a band-shaped central region configured to be in contact with an upper surface of the nail;
• and
• an insertion edge region continuously extended from at least one end of the band-shaped central region and configured to be inserted between a lateral nail edge and a lateral nail fold, the insertion edge region configured for being inserted into the nail along a lateral edge of the nail, wherein
• when a direction of a base side of the nail is defined as an upstream and a direction of a tip side of the nail is defined as a downstream in a state that the corrector is attached to the nail, a screw impeller-shaped portion is formed on a portion including an end portion of an upstream side of the insertion edge region and a hook portion is formed on a downstream side of the insertion edge region in comparison to the screw impeller-shaped portion to hold the lateral nail edge of the nail or a lateral edge of a nail tip,
• the screw impeller-shaped portion has a shape curved downward at an angle of 90° or less,
• in a state that the deformed nail corrector is attached to the nail, a length of the screw impeller-shaped portion measured along a width direction of the nail is increased from the upstream side to the downstream side and is equal to or more than 5% of a width of the insertion edge region measured along the longitudinal direction of the nail, and
• the hook portion is curved downward at an angle of 90° or more.

A system for correcting a deformed nail combining a pair of deformed nail correctors formed in a band shape and configured to be attached to both left and right sides of a nail, each of the deformed nail corrector comprising:

• and
• an insertion edge region continuously extended from at least one end of the band-shaped central region configured to be inserted between a lateral nail edge and a lateral nail fold, the insertion edge region configured for being inserted into the nail along a lateral edge of the nail, wherein

• the hook portion is curved downward at an angle of 90° or more, and the pair of the deformed nail correctors formed in the band shape are laminated at the band-shaped central region and fixed with each other by an adhesive agent.
