4 Claims.
Increasing use of the amnesic method of relief of pain in labor by the use of drugs which obliterate the memory of events in labor, has necessitated more constant nursing supervision of the patient, to prevent infection from selfcontamination of the vulva and injury from accidental rolling off the bed.
Mental excitation under this treatment varies with the temperament of the patient and the drugs used, but in some cases the patient may be very restless, trying to sit up and flinging her arms and legs about in forcible, incoordinate movements. During the pains she may subconsciously try to alleviate her discomfort by pressing her fingers against the vulva and thus infect herself unless restrained by the nurse.
l-leretofore, accidental rolling off the bed, has been prevented by fastening boards or rails to the sides of the bed or using the crib type of bed with perpendicular metal sides which can be raised into position.
The objections to this type of bed are that the patient may become apprehensive prior to the induction of amnesia by the implied necessity of restraint and after she has been rendered amnesic, she may bruise her arms or legs by striking them against the metal sides. Furthermore, there is the added objection of the interference with the nursing and medical care of the patient, offered by the perpendicular metal sides,
It has been to overcome such difficulties as those above discussed, that the present invention has been devised. With this object in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.
Figure 1 is a side elevation of a bed constructed in accordance with the invention.
Figure 2 is a top plan view.
Figure 3 is a vertical transverse sectional view on line 3-4 of Figs. 1 and 2 showing the upward- 1y swingable frames of the mattress-supporting means in lowered position.
Figure 4 is a view similar to Fig. 3 but showing the frames swung upwardly.
Figure 5 is a perspective view showing one end of the rigid frame structure upon which the upwardly swingable frames and their operating means are mounted.
Figure 6 is a fragmentary disassembled perspective view showing the preferred manner of connecting the foot lever and its pedal.
Figure 7 is a perspective view illustrating the manner in which power for raising the upwardly swingable frames is transmitted from one end of the bed to the other.
Figure 8 is a diagrammatic end view showing the manner in which the ordinary hospital-bedsize mattress used on the bed may be converted into a flat-bottom trough to confine a patient upon the central longitudinal portion of said mattress.
A preferred construction has been illustrated and will be rather specifically described, with the understanding, however, that variations may be made within the scope of the invention as claimed.
A rectangular frame 9 is provided, said frame having parallel side bars or rails l0 and parallel end bars ll welded or otherwise rigidly secured to said side bars. 'At the four corners of the frame 9, vertical plates l3 are secured to and rise from the ends of the side bars or rails ll}, said plates 13 being disposed in planes extending longitudinally of the bed and projecting beyond the ends of said frame 9 for attachment to head and foot frames l4 and I5 of any desired form. It is preferable that the outer ends of the plates l3 be bent laterally inward to provide flanges 16 which may be secured to the head and foot frames l4 and I5 by suitable bolts ll. Additional end bars i8 are spaced well above the end bars H and are secured at their ends to the upper ends of the plates 13 by welding or in any other suitable manner. Two additional side bars [9 are disposed well above the side bars or rails Hi and the ends of said additional side bars I9 are provided with inwardly directed arms 20 which normally rest upon the end portions of the upper end bars [8, the inner ends of said arms 20 being pivoted at 2! to said end bars I8 on axes extending longitudinally of the bed, thus permitting upward swinging of the arms 20 and the side bars [9 secured thereto, as shown in Figs. 4 and 8. In the present showing, the arms 20 and side bars [9 are formed from angle iron or steel welded together, and notches 22 are left at the junctures of [9 and 20, to receive the upper end portions of the plates I3 when the two swingable frames (formed by It! and 20) are in lowered position. These frames carry the longitudinal side portions of a conventional bed spring or other mattress support 23 (see Fig. 2), and the central longitudinal portion of this spring or the like 23 is carried by the central portions of the upper end bars l8. From Fig. 2, it will be seen that the longitudinal edges of the spring or the like 23 are secured in a conventional manner to the upper side bars I 9, and that the ends of said spring or the like 23 are similarly secured to the arms 26 and the central portion of the end bars l8. When the frames are lowered, the conventional mattress 214 (Fig. 8) will be in a normal horizontal position throughout its area and when said frames are swung upwardly to substantially 45 to the horizontal, as seen in Figs. 4 and 8, the mattress will be converted into the shape of a flat-bottomed trough with its inclined longitudinal side portions in contact with the patient 25 lying upon the central longitudinal portion, the patient being thus confined in the most desirable position and being prevented from rolling off the bed. In the preferred construction, the pivots 2| are spaced inwardly from the edges of the mattress a distance substantially equal to one-third the width of said mattress. Thus, when the frames (formed by 19 and 20) are upwardly swung, the outer two-thirds of the mattress will coact with the central third in forming the trough-like support to confine the patient as fully indicated in Fi 8.
There are two levers 26 and 21 at each end of the frame 9, said levers being disposed transversely of said frame at the outer sides of the lower end bars ll. These levers are fulcrumed between their ends to the bars I I, the inner ends of said levers are pivotally and slidably connected with each other as denoted at 2B, and the outer ends of said levers'are connected by upstanding pivoted links 29 with the arms 20, so that by operation of the levers 26 and 21, the two longitudinal side portions of the mattress may be simultaneously raised or simultaneously lowered, as required. The fulcrums of the levers 23 are denoted at 33 and they may be in the form of rivets or the like. To fulcrum the levers 27, however, we have illustrated a longitudinal rock shaft 31 which passes through suitable openings in the end bars II and is welded or otherwise secured to said levers 21. Due to this rock shaft, it is insured that operation of the levers and links at one end of the bed will occur simultaneously with operation of the corresponding links and levers at the opposite end of said bed.
For the purpose of operating the levers 26 and 2! and the connected links 29 at one end of the bed, we have disclosed a foot lever 32, one end of which is fulcrumed at 33 to one of the lower end bars II, the other end of said foot lever being suitably connected with an appropriate pedal 34. The intermediate portion of lever 32 is linked to the connected inner ends of the levers 26 and 2'! by a link 35 hanging from the connection 28 above described. The outer end portion of the foot lever 32 is operable in a slot 36 in an angular bar 3? which is suitably welded to the frame 9, or otherwise secured thereto, and at the lower end of said slot 36, a notch 38 is provided having a hook-like upper end 39. When the parts are in position to support the mattress 24 horizontal, the lever 32 is in the upper end of the slot 36. When the mattress shape, however, is to be converted into the form shown in Fig. 8, it is simply necessary to depress the pedal 34. This moves the parts from the positions shown in Fig, 3 to those shown in Fig'. 4 and said parts will be held in these positions when the lever 32 is sprung into engagement with the notch 38. To restore the mattress to horizontal, it is simply necessary to laterally spring the lever 32 out of engagement with the notch 38 and thus permit return of the parts to normal positions.
While it is preferable to tie the mattress to the spring or the like 23 at various points, we also prefer to provide mattress stops 40 on the end bars 18, and said stops may also act as handles when carrying the frame 9 and the parts thereon, disconnected from the head and foot frames l4 and I5.
On admission of a prospective mother to a labor room equipped with the invention, she notes nothing particularly unusual about the appearance of the bed which she is to occupy and thus, she is not frightened nor excited in any manner. When she has reached the stage of labor indicated for induction of amnesia, administration of the desired drug is effected and when the patient begins to sleep, the foot pedal 3 is quietly operated to simultaneously raise both longitudinal side portions of the mattress 24 as seen in Fig. 8, thus forming a fiat bottomed trough upon which she is confined in the most advantageous position for periodic examination and for comfort. Obviously, she is now prevented from rolling off the bed and furthermore, she cannot injure herself in any way no matter how violent she may become during sleep, in which connection please observe from Fig. 8 that the edges of the mattress slightly overlap or extend belond the side bars l9 preventing the patient from striking her hands, wrists, knees or feet against said side bars. Use of the invention not only confines the patient in the most advantageous position for attention by the nurse and doctor but if desired or necessary, the patient may be literally held down in the trough without injury by using rolled-up sheets or suitable canvas straps across chest and legs when restraint is needed. When she is to be taken to the delivery room, the sides of the mattress may be lowered by simple operation of the foot lever and during descent of the upper side bars l9, there is no danger of these bars clamping the hanging sides of the bed clothing against the underlying side bars or rails It).
From the foregoing taken in connection with the accompanying drawings, it will be seen that novel and advantageous provision has been made for attaining the desired ends, and attention is again invited to the possibility of making variations within the scope of the invention as claimed. Moreover, it is to be understood that the invention is not restricted to use for labor purposes but may be employed for any other purpose whenever advisable.
