Abstract

A mouth-held device is described that can be used by individuals having limited or no use of the hands. The device comprises a V-shaped plastic member having a shaft attached. The V-shaped plastic member must be able to soften at or near the boiling point of water and, at such softening point, to take an impression of the teeth of the individuals having limited or no use of the hands. When cooled to at or near body temperature, however, the V-shaped member must be rigid and non elastic and capable of retaining the impression of the teeth. The shaft attached to the V-shaped member can have various implements fixed to it that allows the individual having limited upper extremity function to perform certain tasks independently.

Claims

1. A mouth-held device for permitting a person with limited or no use of the hands to independently perform certain tasks or activities, which device comprises:

(a) a substantially V-shaped plastic member including an integrally formed socket and formed of a material that is softenable at or near the boiling point of water for the purpose of taking impressions of the teeth of the person, but remaining rigid and nontractable when at or near body temperature;

(b) a shaft having one end secured within the socket, whereby when the plastic member is softened, the angular position of the shaft relative to the plastic member may be varied; and

(c) the other end of the shaft being configured for attachment to an implement for performing a given task or activity when the plastic member is held in the mouth of the person.

2. The mouth-held device of claim 1 wherein the material forming the plastic member is a thermoplastic copolymer having a melting point of about 81°

-96°

C., Vicat temperature of about 57°

-79°

C., and a flexural modulus of about 100-380 mpa, the copolymer being capable of taking an impression when at or above the softening point and retaining the impression when at or near body temperature.
