4 Claims. (Cl. 12S-33) The invention relates to therapeutic apparatus.

The object of the invention jis to provide apparatus for completely rotating a patient longitudinally and on a transverse axis to promote circulation of the blood of the patient. It has been found that When a patient is rotated through the air longitudinally, the circulation of the blood is greatly improved, with a resultant improvement in general health. This object isf attained primarily by providing a supporting structure on which the patient is rmly secured in a lying or recurnbent position, and operating the structure on a transverse axis to completely revolve the patient through the air to subject the patient to centrifugal force. This rotation of the patient has been found to increase the activity of the circulatory system and to greatly improve general health. Y

Another object of the invention is to provide.

The invention is exemplified in apparatus comprising a pair of standards I5 built of structural steel. The standards are spaced apart so that the supporting structure for the patient masr be rotated between them through a complete circle and the standards are secured in spaced relation to cross-members I6. Bearings I1 are fixed on the upper ends'of the standards andare adapted to rotatably support a shaft l'land a vcoaxial trunnion I9. These trunnions are disposedat ya suliicient distance from the floor to permit the supporting structure for theV patient to rotate .through 360 above the floor.

The rotatable structure for supporting the patient comprises a seat section which has secured thereto a hanger 23 to which trunnion I8 is Vi'lxed and a hanger 24 secured to shaft I8; a back section pivotally supported from the seat section so it may extend substantially in the plane of the seat section and adjusted upwardly to support the back of the patientk in dierent inclined positions; a foot-rest carried by the outer end of the seat section and against which the soles of the feet of the patient may be held; and a head-rest carried by the back section; all adapted to be rotated together with a patient secured thereon when the shaft |8 is driven.

The seat section is formed of a plate 20 of heavy steel with integral anges 2| which form sides of the supporting structure between which the patient is secured. The inner end of plate 20 is Welded to a cross-member 22 which is integral with and rigidly connects hangers 23, 24. The back section is formed of a plate of metal 25 which is formed with an integral reinforcing flange 25a at its inner end and astiffening flange 25la atits outerend. Plate 25 isl-pilvotallyv-connected to the seat section byvpintles 2'6..Which extend through flanges 2| andthe hangers 23, 24,

respectively, and are formed on lugs which are riveted to plate 25vand flange 25a. Plate 25 vcan be swung from a position substantially aligned with plate 20 to support the patient in a lying position and upwardly to different angular positions for supporting the patient during rotation, in different recumbent positions. The back section is adaptedto be locked in diierent angular positions by locking devices,each of which comprises a pin 28 slidably mounted in acasing 29 and normally pressed by a spring 30 to extend through any of an `arcuate series of holes 23a formed in the side flanges 2| of the seat section. A cam-handle-SI engages casing 29 and is adapted when turned to Withdraw the pin 28 from locking engagement with holes 29. Each casing 29 is secured-to the backV 'face of plate 25 and is extended at 32 to support the outer` end of pin 28. A reinforcing strip 2 Ia is secured to the outer side of each of the flanges 2| and is provided with holes corresponding to the holes for the locking pin 28. Rotation of handles 3| will withdraw pins 28 from lugs 32 and the holes 21 in side fianges 2| so the back section may be angularly adjusted. When the handles are released the pins will lock the back section. This exemplies means for securely locking the back section in different inclined positions. A head-rest and support 33 is fixed to the upper end of a bar 34, which is slidably mounted in a channel in a bracket 35 which is fixed to the back side of plate 25. Bar 34 is provided with a series of holes 36 which are adapted to receive a locking screw 31 to position the head-rest for different persons.

The shoulders of the patient are firmly held on the revoluble support to prevent the patientv sliding off the back-rest by a pair of hook-shaped shoulder-engaging members or stirrups 38 which are supported on the plate 25. Each of these stirrups 38 is padded to fit over and partially around the front of the shoulders of the patient and supported by an arm 39 which is pivoted at 40 to a bracket 4|. Bracket 4| is slidably adjustable on bracket 35, to permit arms 39 and stirrups 38 to be adjustable longitudinally with bracket 4|, so the stirrups 38 can be firmly pressed against and seated on the shoulders of patients of different heights. Guide-bracket 4| is provided with a series of holes 42 for the reception of a spring-pressed locking-pin 43 to secure bracket 4| in different positions. Pin 43 is pressed by a spring 44 into holes 42 and is releasable by a cam-handle 43a to lock guidebracket4l which carries arms 39 to bracket 35, When pin 43 is withdrawn from holes 42 the stirrups can be set against the shoulders and locked. Arms 39 extend through slots 39EL in flange 251A to permit limited lateral pivotal movement so the stirrups will fit snugly against shouldersY of different widths. A strap 46, the ends of which are fixed to eyes which are fixed to plate 25 adjacent the sides 2| and which is provided with a buckle 41, is adapted to extend across the chest and hold the upper portion'of thel torso of the patient firmly on the back section. A Y strap 48 provided with a buckle is similarly connected to the body-supporting plate 20 and is adapted to extend around the hips er waist to hold the seat .of the patient firmly cn Vthe rotatable support. VStirrups 49 formed of Vunder the instep for pulling the stirrups to stretch the legs of the patient and press the soles of the feet firmly against the inner face of plate 56. 1

The foot-rest comprises a transverse upstandin g plate 56 against which the soles of the feet of the patient are adapted to be pressed. Plate 56 is formed as a part of a frame which comprises' side iianges 51 and a cross-plate 58 between said flanges and secured thereto and to plate 56. This frame is supported for sliding adjustment on a pair of angle-beams 59 which -aresecured tothe underside of plate 28, project longitudinally therefrom, and are connected at their outer'ends by a bar 69. This foot-rest j frame is slidably supported on beams 59 by anglemembers 6| fixed to the outer sides of flanges 51 and adapted to rest on the top fianges of beams 59 .and aguide-Vstrip adapted to lap the outer sidesnof the vertical flanges of beams 59. Beams 59 are each provided with a series of holes 63 which are adapted to receive spring-pressed lockingpins 64. Each locking-pin 64 is slidable in a casing 65 which is secured to one of the anglemembers 6| and is operable by a cam-handle 66 to withdraw the pin from engagement with holes 63. When the locking-pins are withdrawn from holes 63 the wall 56 forming the foot-rest can be adjusted inwardly or outwardly to position it for patients of different lengths of legs.

Means comprising a system of cables and pulleys is provided for pulling hooks 5| to which the foot-stirrups 49 are attached for stretching the legs of the patient and pulling the feet against foot-rest 56. This system comprises a pair of cables 68 having one of their ends connected to the hooks 5|, respectively. Each cable 68 passes around a pulley or sheave 69 supported in brackets projecting from plate 56, thence through plate 56, and around a pulley 10, thence around a pulley 1| supported from plate 56 and to a buckle 12. Pulleys 18 are supported in a shackle 13 which is connected by a spring 14 to a lug-15 fixed to plate 20. A strap 16 has one of its ends fixedly secured to plate 28 and its other end adjustably secured in buckle 12. When the patient has been secured on the seat and back sections of the supporting structure, and the foot-rest has been adjusted so it will be normally spaced from the feet a distance corresponding to the stretch of the legs desired, the stirrups 49 will be connected to hooks 5|, and strap 16 will be taken up at buckle 12 so that the ends of the cables 68, which are connected to buckle 12, will be pulled inwardly and exert an outward pull on hooks 5| and stirrups 49 until the patients feet are firmly held against the inner faces of wall 51 of the foot-rest. The strap 16 will then be secured in its taken up position in buckle 12. The spring 14 applied to pulley 10, will exert tension on hooks 5| and firmly hold the feet of the patient against wall 56 of the foot-rest. This exemplifies means for stretching the legs of the patient the desired degree and holding the feet firmly against the foot-rest during rotation of the supporting structure and the patient. Strap 16 and pulleys 10 and the reaches of the cables between them are disposed between ,the legs of the patient and strap 16V is readily accessible for adjustment by the patient.

Power mechanism for revolving the supporting structure with the patient thereon comprises an electric motor mounted on a platform 8| at one side of one of the standards I5; a worm 82 fixed to the shaft of motor 80; a worm-gear 83 engaged by worm 82 and fixed to a shaft 84 which is journaled in a gear-case a worm 86 Afixed to shaft 84; and a gear 81 fixed to trunnion shaft I8. The gear-case 85 encloses the gearing and is supported on a platform 8|. The motor lispreferably of the reversible and variable speed type so that the patient can be revolved forwardly or backwardly on the transverse axis of the supporting structure and at different speeds.

A handle-bar 88 is secured to arms 89 which are coaxially pivoted to the side flanges 2| so that the handle-bar may be adjusted to and from the patient to position it within convenient reach of the hands of the patient. Holes 90 in sidefianges 2| ,are engaged by locking-pins 9| to lock the handle-bar in its desired position.

In operation the patient is first seated on plate 28. The back plate 25 is adjusted to support the back of the patient in a substantially horizontal or a recumbent position, as may be desired. Strap 46 is secured around the chest ofthe patient and strap 48 is secured around the Waist. The head-rest may also be adjusted to suit the patient. The stirrups 38 are then adjusted downwardly and locked to firmly engage the shoulders of the patient. Stirrups 49 are then secured to the vfeet of the patient. The foot-rest is adjustedV to a point a short distance from the feet and locked` The strap I6 is then taken up to pull the stirrups 5I outwardly, stretch the patients legs, and hold the feet firmly against the wall 56 of the frame and then secured in its taken-up position. The spring 13 exerts a tension on the cables 68 to exert a pull on the stirrups l and retain the feet of the patient against wall 56. When the patient has been thus firmly secured on the supporting structure, the motor 80 is operated to revolve the supporting structure on the axis of trunnion I9 and shaft I8 at the desired speed. In practice it has been found that a speed ranging from 1 to 4 revolutions per minute produces beneficial results. The revolving of the patient while secured on the supporting structure with the legs stretched, has been found to greatly promote the action of the circulatory system and improve the health of the patient.
