FIG. 1 is a perspective view of a pillow device for a patient with cervical intervertebral disc prolapse according to the present invention, and FIG. 2 is an exploded perspective view of a pillow device for a patient with a cervical intervertebral disc prolapse according to the present invention.
A pillow device for a patient with cervical intervertebral disc prolapse according to the present invention comprises a shape memory alloy wire and a wire fixture, a power section (100) constituted by a horizontal ratchet, a linear movement of the horizontal rack into rotational motion, And a driving unit 300 for converting the rotational motion of the rotary unit 200 into linear motion and adjusting the displacement of the head plate which the user's head touches.
The power unit 100 includes a shape memory alloy wire 110 that shrinks due to a thermal effect when current flows through electrodes connected to both ends of the wire and a horizontal rack 120 that converts power due to the contraction action of the wire into a horizontal displacement ) And fixtures of wire and horizontal racks.
The large lower plate 130a is coupled to the small lower plate 130b by the plate bolts 150 and the plate nuts 160 and the small plate 130b is also coupled to the first wire 130a by the plate bolts 150 and the plate nuts 160. [ And is combined with the fixing table 140a and the second wire fixing table 140b. The end portions of the shape memory alloy wires 110 that flow current from the power supply as the actual power source are fixed by the first wire fixing table 140a and the second wire fixing table 140b, respectively. The guide bearing 170 which provides a path for increasing the length of the shape memory alloy wire 110 is joined to the small lower plate 130b by the guide bearing fixing bolt 180 to maintain its height and the shape memory alloy wire 110 are fixed by a tension force as they pass between the guide bearings 170.
The fixed shape memory alloy wire 110 passes through the first through hole 140a and the second through hole 140b of the horizontal rack 120 so that when the wire shrinks, , Which serves to change the power of the machine moving into a horizontal displacement. The horizontal rack guide 190 coupled with the small lower plate 130b by the plate bolts 150 and the plate nuts 160 serves to limit the movement of the horizontal racks 120 in the horizontal direction.
The rotation unit 200 includes a first gear 210, an axis holder 220, a shaft 230, a second gear 240a, a third gear 240b, a second gear cover 250a, 250b and an auxiliary device for engagement of the gear and the shaft.
The shaft holder 220 is connected to the horizontal rack guide 190 by the shaft holder fixing bolts 260a and b and is engaged with the small lower plate 130b by the plate bolt 150 and the plate nut 160. [ The shaft 230 is fixed by the shaft holder 220 and the rotation of the first gear 210 is transmitted to the second gear 240a and the third gear 240b by the shaft. At this time, the gear ratio of the second gear 240a and the third gear 240b is the same, but the gear ratio is different from that of the first gear 210, so that the gear ratio is amplified by the ratio.
The driving unit 300 includes a first vertical rack 310a, a second vertical rack 310b, a first spring 320a, a second spring 320b, a first spring guide 330a, a second spring guide 330b, A first head plate 340a, a second head plate 340b, and a head plate joining bar 350. [
The displacement amplified by the second gear 240a is converted into a linear motion by the first vertical rack 310a coupled to the first vertical rack 310a by the first head fixing bolt 360a, The first head plate 340a is linearly moved together to drive the apparatus. Similarly, the displacement of the third gear 240b is also converted into a linear motion by the second vertical rack 310b coupled to the second vertical rack 320a by the second head fixing bolt 360b. 2 The head plate 340b is linearly moved together to drive the apparatus. The first headboard 340a and the second headboard 340b are joined by the headboard joining bar 350 and have the same displacement.
A first spring 320a is provided at the lower portion of the first vertical rack 310a to prevent the headboard from diving and bear the load of the head and neck portions and to provide restoring force to the first vertical racks so that the headboards 340a, . At this time, the first spring guide 330a fixed to the small lower plate 130b limits the path of the first spring 320a in the vertical direction. Likewise, a second spring 320b is provided below the second vertical rack 310b. At this time, the second spring guide 330b fixed to the small lower plate 130b restricts the path of the second spring 320b in the vertical direction. At this time, the displacement of the spring is the same as the displacement of the vertical racks 310a, b.
FIG. 3 is a state diagram illustrating an operation principle and a use method of a pillow device for a patient with cervical intervertebral disc prolapse according to the present invention. Hereinafter, the principle of operation of the pillow device according to the present invention will be described with reference to FIG.
When electric current is supplied to the shape memory alloy wire 110 by the power supply device and the wire is contracted due to the thermal effect of the current, the horizontal rack 120 connected to the wire makes linear motion, and the first gear 210 Is rotated. When the rotation of the shaft connected to the first gear 210 is transmitted by the rotation of the second gear 240a and the third gear 240b, the first vertical rack 310a and the second vertical rack 310b are amplified The vertical displacement is reduced. As the head plates 340a, b connected thereto are lowered, the back of the user's head is lowered, and the cervical spine extension motion is induced. The shape memory alloy wire 110 is loosened again and the first vertical rack 310a and the second vertical rack 320b are rotated by the restoring force of the first spring 320a and the second spring 320b, The second gear 240a and the third gear 240b are rotated and the first gear 210 connected to the same axis is also rotated so that the horizontal rack 120 connected to the first gear 210 rotates And a linear motion is performed. This action causes the head plates 340a, b to return to the initial position, and the head and the neck of the user rises again. It is more effective to use a support cushion (400) that heightens the shoulder portion to further improve the degree of cervical extension of the user.
