FR2551966A1 - Device for measurement and signalling of articular amplitude - Google Patents

Abstract

Device for measurement and signalling of the articular amplitudes of the human body. The invention relates to a device measuring the amplitude simultaneously with the movement and signalling with electronic elements preselected angulations. It is constituted by a casing 1 articulating around a disc 2 which is graduated and weighted 3 at its base. When the casing 1 is put on a segment in motion of a human body, the casing 1 varies its position with respect to the disc 2 and it is possible directly to read the angulation on a marker 5 situated at the bottom of the casing. The system is completed by two elements which make contact, one 4 which is adjustable on the disc, the other fixed on the casing opposite the marker 5. This contact via a battery 6 and a time-delay relay 7 supplies the audio (buzzer) 8 and visual (bulb) 9 signalling elements and optionally remotely a pulse counter 10. The device according to the invention is in particular intended for physical medicine and kinesitherapy.

Description

DESCRIPTION
The present invention relates to a device for measuring and signaling the articular amplitudes of the human body (Kinesiometer or Kinesiometer).

 The measurement of a joint amplitude is traditionally done with a goniometer, it is a static measurement. Amplitude control is generally done by mechanical locking on devices specific to each joint; it is in fact a limitation of the joint stroke.

 In the device according to the invention, the measurement of the amplitude is simultaneous with the movement. It consists of a transparent plastic case with two compartments.

 In the first compartment is articulated vertically a graduated disc (3600) sealed at its base, which therefore always has the same orientation in the vertical plane, it is the bootmaker who fixed on a member segment (static or dynamic) tilts and determines an angle.

The angles are read at a mark represented by a line on the base of the box opposite the lower end of the disc (00) when the assembly rests on a horizontal plane.

 This device is completed by a signaling system consisting of a free electrode, adjustable around the disc and a fixed electrode, located on the base of the case opposite the mark. Depending on the angle chosen, the electrodes with the movement will establish contact. This contact can be mechanical, electro-magnetic or by photo resistance (photo window coupler).

 The second compartment of the shoemaker comprises, the battery and the electronic elements: timed relay regulating the contact time, audio and visual elements (buzzer and bulb). This independent box can be supplemented remotely with a pulse counter memorizing the number of movements.

 Figure I shows on one side an example of the device according to the invention (mechanical contact).

 Figure II shows from the same example.

the section according to the invention.

 The device shown in Figure I comprises a boot (I) having dimensions of the order of 10 cm by 5 cm and a thickness of 2.5 cm. In the front compartment is articulated a disc (2) graduated and sealed with its base (3), in addition, it comprises a mobile electrode (4) which during an angulation of the case (I) will establish contact with a fixed electrode (5), located on the box, next to the angle reading mark.

 The second compartment contains the battery (6), the electronic elements, time relay (7), buzzer (8), bulb (9), a socket (IO) for possible connection of a pulse counter.

 The device according to the invention is particularly intended for physical medicine and physiotherapy.
