Title: Lumbago preventive apparatus
Inventor: NAKAMATSU YOSHIRO
IPC: A61B5/107
Filed: 1993-10-20
Abstract: PURPOSE:To prevent and cure a lumbago by adjusting the angle of a hip or the associated parts properly, which is detected by the contact between a weight and a detective panel which contacts with the weight. CONSTITUTION:A detector 1 which is attached to the back 2 of a person's hip and which detects the inclination of the back 2 is composed from a metallic weight 4 hanging at a fulcrum 3 and a metallic detective panel 5 surrounding the metallic weight 4. An alarm 6, which is provided with a battery 7, a buzzer 8 and a power switch 9, is held in a pocket of a coat and is connected with a detector 1 using a lead 10. When used by turning on the power switch 9, if a person who wears the detector 1 has a poor posture which might cause a lumbago, the detective panel 5 of the detector 1 tilts and contacts with the weight 4 hanging and a current runs from the battery 7 to the switch 9, the detective panel 5, the weight 4 and the buzzer 8, and then the buzzer 8 rings. If the person hears the sound and keep the posture right, the sound of the buzzer 8 stops, because the angle of the back 2 becomes normal and the detective panel 5 leaves the weight 4.
