CORPORATION OF PENNSYLVANIA OBSTETRICAL BED Application filed September 11, 1929.. Serial No. 391,774.

This invention relates to hospital beds, and especially to beds for gynecologicaland obstetrical uses.

It is among the objects of the invention to provide a bed of the type referred to, which 1s. of ordinary hospital size, and built from the materials customarily used in such beds,

is strong, rigid, of simple construction, read-4 ily manipulated, adapted to provide maximum comfort to the patient while rendering easier the manipulations, assumption of various positions, and other operations incident to gynecological and obstetrical practice A particular object is to provide a bed of the stated type which is particularly adapted to facilitate infant delivery, which materially reduces oreliminates manualshifting of the patient during delivery and effects assumption of the various positions by mechanical means, permits easyhandling of heavy patients, and is provided verti- .cally and laterally adjustable leg-supporting means. l

The invention described in connection with the accompanying drawings, in which Fig. 1 is a perspective viewof the preferred embodiment; Fig. 2 a plan view of the bed, parts being brokenaway to'assist in illustration; Fig. 3a view similar to Fig. 1 with the mattress removed and with the bunk moved to a delivery position; and Fig. 4 a cross section of a portion of the bed, taken on line IVIV, Fig. 2; and Fig. 5 a 'fragmentary perspective side view, partlyin section, of the leg elevating mechanism shown in Fig. 3. i r

The bed provided by this invention comprises a bedstead frame structure of any suitable construction which carries a patient-supporting bunkin the form of a platform having connected head and foot portions adapted to be moved longitudinally of the bed the foot portion rolling around the foot'of the bed to shift the head port-ion toward or from the foot of the bed. 5 The bunlris preferably .slidably supported oil-guides carried by the bed frame, and guide rollers-mounted on the head portion of. the bunk run on trackways carried by the guides. The: bunk may be shifted in any suitable manner, for example by a suitably actuatedchain connecting its The bed is also provided with leg stirrups which are adjustable for independently varying'both the vertical elevation and the angular extension of the patients legs, and it also embodies means for quickly and easily elevating-the foot end. V Having reference now to the drawings, the embodimentshown comprises a bedstead including side sills 1, cross braces 2, and end frames 3 whose side members l are preferably tubular, all connected invthe customary manner to form a strong, rigid structure. Mounted longitudinally of the bed are spaced guides 5, for carrying the patient-supporting bunk. l

Aparticular feature of the invention resides in the provision of a longitudinally movable bunk which rolls around an end of the bed, and which in no way hampers acand a lower or foot portion 7 adapted to be .coiledor rolled. In the form shown, the foot portion comprises'slats connected to one another and to the head portion by articulated joints, preferably in a manner presently to be described. 'The bunk is supported by the guides 5, and to assistin shifting it and to prevent lateral displacement, the head portion' of the bunk is provided with rollers 8 which run on trackways 9, preferably formed by angles connected to the bottom of the guides as shown in Fig. 4c.

7 -The bunk-shifting means shown comprise rotatable shafts 10 and 11' mounted transversely ofthe bed adjacent the end frames inbearing members 12 connected to the side sills. Each shaftis provided centrally with sprocket wheel 13, and at its end with a geanl l which mesheswith a pinion 15 on a stub shaft 16 mounted in'bearing 12. A

sprocket chain 17 connected to opposite ends chain 17 along the lower bunk portion, con

necting its links to individual slats, as may be seen from Figs. 1 to 3. When the foot end of the bunk is in a patient-supporting position, guides support the slats at the sides and prevent tipping, and by rounding the guides at the foot end, as shown in Fig. 3, the slats slide easily thereover when the bunk is moved.

Leg-supporting rods 20,'provided with-stirrup rings 21, and each having a horizontally offset portion 22, are slidably mounted in tubular side members a of the foot end frame. The rods may be held at any desired height by means of set screws 23, and the distance between the rings may be varied by rotation of the rods in their supports, thus providing independent vertically and laterally adjustable supports for the legs of a patient.

As is known, it is desirable at times to elevate the foot of beds of this type. The invention also provides means for accomplishing thisobject quickly and easily. As seen in Figs. 1 and3, the side members of the foot end frame are slidably disposed in housings 24 carried by extension legs 25 and connected by a rotatable shaft 26, on which there are mounted pinions 27 meshing with racks '28 connected to the legs of the end frame. The elevating mechanism is actuated ,by means of a crank 18a applied to shaft 26, which crank may be the same as, or interchangeable with bunk crank 18 to eliminate any possible confusion. When elevated, as shown in Fig. 1,the bedmay be held firmly by a pivotally mounted pawl or latch bar 29. The bed is also provided with metal rings 30 connected to the side sills 1. for receiving hand-engaging straps. A shelf 31- pivotally connected to the right hand side of the head end frame is provided for anesthetists supplies. and another shelf may be similarly disposed in a bracket 32 connected to the foot end frame. A hooked extension rod 33 is disposed in one of the head frame side posts, for use with enteroclysis or like treatments.

. The bunk is. of course, provided with a mattress 34:, Fig. 1, held in position on the bunk in any suitable manner, as by snap-conv necting straps 35.. The foot portion of the mattress is preferably segmented or'articulated, so as to roll-easily with the foot portion of thebunk in passing around the end.

The use of'the bed is exceedingly simple.

"tially equal length, provision is made for different size patients. Normally, of course, the foot of the bed is lowered to the position shown in Fig. 3. Thus no pulling or lifting of the patient is necessary, which relieves the attendants and ra'd-d-s'to the patients comfort, and should the patient move out of position, she can be returned by simple movement of the crank. Patients are thus easily and readily brought into position at any desired rate, and even the heaviest patients may be handled with great ease, and the position of the foot stirrups can be quickly changed as need be. Because the bunk rolls under the end of the bed, the surgeons and nurses access to the patient. is in no way interfered with. Thus the invention provides a bed which eliminates much manual efiort on the part of attendants, simplifies obstetrical practice, renders manipulation easyand efficient, is simple and readily operated, and which in general makes for a greater degree of comfort for and more eificient cooperation between the patient, surgeon and nurses.

-'According to the provisions of the patent statutes, we have explained the construction and operation of our invention, and have illustrated and described what we consider to represent its best embodiment. However, we desire to have it understood that,within the scope 'of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
