30. There is thus adaptability for concavity of the pad 29 to be toward the bed mid section 11, in thus locating the torso of the individual or patient properly, say so as to have the crest of the ilium at a neutral region or axis δ 31 for the radii 32 of the rocker 5. Under such circumstances as the patient upper torso be elevated to approach sitting posture as to the mid section 11, say as for eating, the block 24 may be shifted and the pad 29 oriented’ for this assembly to serve as an arm rest.

A wing nut 33 is at a block 34 thereby adjustably positioned along a bed section side rail, herein shown as the section 10. A bracket 35, rising from and integral with the block 34, mounts a pivot rod 36 (Fig. 3). A footrest section 37 on the rod 35 (Fig. 3) lias fixed 15 therewith an arc back plate 38 with a slot 39' on an arc from the rod 36 as a center (Fig. 4). Parallel to the back plate 38, and in abutting relation thereto, companion footrest section 39 (Fig. 3) has a plate 40 (Fig. 4) carrying a hand wheel 41 rotatable for drawing a head 42 ²⁰ against the opposite side of the plate 38. The plates 38, 40, are on the respective inner ends of the sections 37, 39. An externally threaded stem 43 from the head 42 extends thru the arc slot 39' to be engaged by the handwheel 41 coacting in holding the sections 37, 39, ⁴⁸ co-planar, or relatively angularly shifted, as may provide comfort rest for the respective feet of the patient at the determined-upon position for the patient with such patient’s crest of the ilium at the neutral axis 31. There may be a further or supplemental rock or pitch given to the footrest sections 37, 39, as an assembly or unit thru the operation of a knurled handwheel 44 (Fig. 3) from the bracket 35 below the rod 36. This handwheel 44 has its stem extending thru an arc slot 45 in a fan plate 46 (Fig. 4) fixed with the section 39.

^δ Wing set screws 47 at guides 48 fixed with the bed under section 6 in the region of the mid section 11, provide adjustable mounting for a U-frame 49. There is thus provided a guard against off-side shifting of the 40 Patient from the bed sections, say as carrying a mattress 50 thereon. The upward extent of adjustment for the top section of the U-frame 49, as parallel to and rockable with the bed, is in position for convenient grasping by the patient. By thus having something to hold to which is moving with the oscillating structure, there is confidence 45 established for the patient, should the patient become perturbed.

The oscillation disclosure with patient placement effectively coact in promoting respiration as well as normal functioning of the internal organs of the patient. Under ⁸⁸ this disclosure there is manually controllable interconnection for synchronization with the oscillation lespiration promotion, introduction as well as variation thereof over a wide or complementary range of inhalant supply and exhalation assistance.

To this end, one of the rockers 5, on its inner face, is provided with an arc toothed section or rack 51. Coaxial with one of the rollers 4 there is a gear 52 (Fig. 8) which may have a normal mesh relation with the rack 51. Whether the oscillation be full or fractional and whether of more or less frequency, the gear 52, as in mesh with the rack 51, acts in synchronized response. This operation may be taken as idle. To effect control, a manually positionable trigger 53 may be swung from its out throw _eg position (Fig. 8) to engage a notch 54 (Fig. 7). There is thus a positive coupling of the oscillating bed driven gear 52, transmitted thru its sleeve 52' and the notches 54, the trigger 53 and a shaft 53' coaxial with the gear 52 and extending thru the sleeve 52' to a disk 55. The 70 oscillation of the gear 52 in rocking therewith the disk 55, is effective thru wrist pin 56 on the disk 55 to reciprocate a connecting rod 57 thereby operating a pump in

ROCKING BED STRUCTURE AND SYNCHRONIZED RESPIRATOR

Charlotte M. Baron, Toledo, Ohio

Application November 7,1951, Serial No. 255,219 3 Claims. (Cl. 128—29) • This invention relates to restoration and promotion of health conditions in an individual, even to the extent of normal breathing and resuscitation.

This invention has utility when incorporated in conjunction with a controllably oscillatable support for a supine individual, specially located, with inhalant supply adapted to be in synchronism therewith.

Referring to the drawings:

Fig. 1 is a side elevation of a readily-shiftable oscillatable support with adjustments and controls therefor;

Fig. 2 shows an adjustable mounting for a shoulder pad for one reclining, or for an arm rest, if the individual approach sitting posture;

Fig. 3 is a fragmentary view of an adjustably mountable foot rest, coacting with the shoulder rest in appropriately locating the individual on the support for therapeutic service;

Fig. 4 is a fragmentary view, from the left of Fig. 3, further illustrating the adjustments for the foot rest assembly;

Fig. 5 is a detail in partial side elevation of that rocker portion identified as projecting upward from the base in Fig. 1;

Fig. 6 is a partial view looking from the line VI—VI, Fig. 5, showing a portion of the rocker face or track, omitting the roller and gear;

Fig. 7 is a detail view on an enlarged scale of the trigger and collar from the left of Fig. 8, and

Fig. 8 is a sectional view taken on the line VIII__VIII

Fig. 5.

Swivel casters 1 with rockable brakes or floor locks 2 portably carry a base frame 3 having rollers 4 to support a rocker 5 portion of a chassis for a support or bed under section 6 provided with two cranks 7; one for shifting a bed head and shoulder section 8, and the other for shiffing a tlfigh section 9 and a lower leg section 10, relatively to a mid section 11. An electric motor 12 is mounted in the base frame 3 and, thru a speed reduction device 13, rotates a crank 14 having thereon an electric motor 15 to adjust a wrist pin 16 in varying the radius for such pin in its action upon a link 17 connected to the bed under section 6. An electric conduit or cable 18 from the section 3 extends to a housing 19 provided thereon with an instrument panel section 20 for determining the oscillation frequency and rock extent effected by the link 17. This electric switch assembly and control has, to the cabinet or housing 19, a power supply line 21 from an outlet fixture 22.

A wing nut handle or screw 23 at a block 24 may serve to anchor such block as slidable along a side rail or the bed head section 8. A wing set screw 25 in the block 24 may fix the up and down adjustment of a rod 26. At its upper end a set screw 27 may adjust and hold a horizontally extending rod 28 as to its slide assembly with the opening in the top of the rod 26. The rod 28, in its extent over the head section 8, has an arc seat or pad 29 adjustably fixed to the rod 28 by a wing set screw

Oxygen gas as under pressure of several atmospheres in tank 59 has flow therefrom thru reducing valve 69 to approximate inhalation pressure in supply to the resuscitator 58 which including some type of reciprocating pump to dispense oxygen gas volumes intermittently in step with the rocking of the bed in the flow of oxygen as to the cabinet 58 by the duct 63, passing therefrom by inhalation duct 63 to the mask 64. A fitting or valve control 65 at the mask 64 may millify the dispensing action of the pump in the cabinet 58. This fitting 65 may nullify exhalation from the mask back to the cabinet 58 by the duct 66. The treatment of the patient effected at the mask 64 may be determined by the valve handle 62 at the cabinet 58. The gas handling may be carried thru as above suggested. The technical advance is based on the inter-connection control (Figs. 5, 6, 7, 8) whereby there may be selected a wide range of synchronized response triggered from the rocking of the bed in breathing gas to the patient.
