20 Claims.

The present invention relates to a bed pan device, and is primarily concerned with the provision of means for supporting a container upon a bed frame in such a condition that the occupant of the bed may readily and conveniently shift the container between a position in which it comfortably and effectively fits the pelvic floor of an occupant of the bed so that such occupant may evacuate the bladder and lower colon, and a position, below the bed, in which the container will not interfere with the comfort of the patient and is accessible to an attendant for removal, replacement or other necessary attention. Among the objects of the invention are to provide a novel mounting and actuating means for such a container; to provide a novel container, consisting of outer and inner receptacles, adapted for the above purposes, the inner receptacle being removable from the outer receptacle for disposal of the contents thereof; to provide a support for such a device of such character that it can be elevated into position for use through a minimum efiort on the part of the occupant of the bed; and to provide means associated with such a receptacle and support to guard against air or liquid flow through the necessary opening in the mattress with which the device is associated. Further objects of the invention will appear as the description proceeds.

To the accomplished of the above and related objects, our invention may be embodied in the forms illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that change may be made in the specific constructions illustrated and described, so long as the scope of the appended claims is not violated.

Fig. 2 is an enlarged fragmental perspective view of a container and mounting therefor forming a part of our invention;

Fig. 3 is an enlarged fragmental plan view of certain operative parts of the mounting device;

Fig. 4 is a fragmental longitudinal section taken substantially on the line 4-4 of Fig. 3;

Fig. 5 is a similar section taken substantially on the line 5-'-5 of Fig. 3;

Fig. 6 is a fragmental plan of a portion of a mattress provided with an opening therethrough, and showing the container of our invention positioned therein; v

Fig. 7 is a longitudinal fragmental sectional view taken substantially on the line 'i---'! of Fig. 6;

Fig. 8 is a fragmentary sectional view showing optional means for supporting an inner receptacle in an outer receptacle or holder;

Fig. 9 is a side elevation of a modified form of container showing its association with the mounting or supporting means;

Fig. 10 is a transverse section taken substantially on the line i0-l ll of Fig. 9; and

Fig. 11 is a plan view of the supporting means of Figs. 9 and 10, the container having been removed therefrom.

Referring more particularly to the drawings, it will be seen that we have illustrated a hospital bed of known construction, and comprising a main frame, indicated generally by the reference numeral l0, and supporting an articulated frame generally indicated by the reference numeral ll and comprising a hinged head section l2, a sta tionary mid-section l3, and hinged sections l4 and It. A relatively flexible mattress I6 is supported on the frame I I in a well known manner.

Within the region of the stationary frame section l3, the mattress I6 is formed with an opening i1 therethrough, said opening being laterally central of the mattress and longitudinally in a position immediately beyond the pelvic region of an occupant of the bed. Preferably, but not necessarily, a generally tubular shield element ill of relatively rigid material such as sheet metal, and provided with a bead 19 at one end, is snugly received within the lower portion of the opening I! to reinforce the lower portion of that opening, and a similar shield 20, having a bead 2 l, is similarly received in the upper portion of that opening, the shield sections i8 and 20 being telescopically associated to permit compression and expansion of the mattress, while maintaining the opening against transaxial collapse. A container, indicated generally by the reference numeral 22, will preferably comprise an outer receptacle or holder 23 and an innner receptacle 2G removably mounted in the outer receptacle. The open mouth of the receptacle 23 is preferably bounded by a bead 25 with which is associated one re siliently expansi-ble end 25 of a flexible sheath 2! preferably formed of liquid proof sheet material, such as rubber, synthetic rubber, or rubberized fabric. The sheath 2'! is generally tubular, and its end 25 may be rendered resiliently expansible by the incorporation therein of a rubber cord or a coiled spring, or the like. At its opposite end, the sheath 2! is outturned to form a peripheral flange 28, and the mating elements of separable fasteners 29 are secured, respectively, to the flange 28 and to the lower surface of the mattress IS in a perimetral grouping around the lower mouth of the opening ll. It will be readily apparent that, when said flange is so secured to the mattress, as the container 22 is moved between the position illustrated: in Fig. '7 and that illustrated in Fig. 1, the end 26 of the sheath 2'! will move with said container to assume the conditions illustrated in said two figures; and that the sheath will, at all such times, prevent air flow through the opening H.

While the receptacle 23 is shown in Fig. '7 to be closed at its bottom, it will be obvious that it need not be. so closed. Its bottom wall may be in the form of a spider; or it may be a mere sleeve without a bottom wall, the receptacle 24 being supported therein in any suitable fashion, as by means of the pins 23 shown in Fig. 8.

At is upper end, the receptacle 24 is provided with an open mouth guarded by a lip portion 30 which, in the position of Fig. 7, lies substantially in the plane of the upper surface of the mattress IS. The lip 30 merges with an upstanding portion 3| of the receptacle 24 which, in the position of Fig. '7, projects upwardly beyond the upper surface of the mattress IE to present, toward the head end of the bed, a shell-like contour to fit the pelvic floor of an occupant of the mattress |5, while the lip 30 underlies and substantially fits the dorsal portion of the occupants trunk, but substantially without supporting pressure thereagainst. The structural details of the receptacle 24 are more fully disclosed and claimed in our co-pending application Serial No. 62,114, filed November 26, 1948, for Bed Pan.

A bar 32, at least a portion of which is cylindrical in transverse section, is adapted to be suitably fixedly supported in brackets 33 adapted to be secured to the frame |U, said bar extending transversely of said frame. A sleeve 34 is mounted upon said bar for oscillation about the axis of said bar; and one or more arms 35, 35' are fixed to said sleeve to move therewith. A bracket 36 is loosely supported on the sleeve 34 and, at its upper end, is bifurcated (Fig. as at 31 to engage the downwardly projecting flange 38 of an angle iron 39 comprising a standard transverse brace incorporated in the frame l0. Obviously, if desired, the bracket 36 may be held against oscillation relative to the aXis of the bar 32 in any other suitable fashion, but we prefer to utilize the brace 39 which is already present in the standard frame I0.

The bracket 36 provides a journal mounting 40 for an arm indicated generally by the reference numeral 4|, the arm being similar in shape and extent to the arm 35, and the journal mounting 40 being located upon an axis parallel with, but spaced below, the axis of the bar 32 about which the sleeve 34 is oscillable. The arms 35 and 35 are pivotally associated with the container 22, and the arm 4| is similarly pivotally associated with said container, the pivotal axes connecting said container with the arms 35, 35 and 4| being parallel with each other and with the axis of the bar 32, and being vertically spaced from each other by an amount equal to the vertical spacing between said bar axis and the axis of the journal mounting 40. In the embodiment of the invention illustrated in Figs. 1-7, a saddle yoke 44 is fixed to the receptacle 23 and provided with pivots 42 and 43 whereby said container is supported upon the arms 35 and 4|, respectively.

Preferably, the arm 4| comprises a tube 45 and a. rod 41 telescopically received in said tube. A pin 46 enters the tubular element 45 to provide an abutment for one end of a spring 48 the opposite end of Which engages the inner end of the rod 41 to urge the same outwardly with the respect to said tube 45. The rod 4'! is provided, in the region received in the tube 45, with a longitudinally extending transverse slot 49 traversed by a pin 50, whereby said rod is held against axial rotation relative to the tube 45 and is limited in its axial movement relative to said tube. When the rod 41 is in the position shown in Fig. 5, the container 22 will occupy the attitude shown in Fig.1.

Where the telescopic association above described is used, it will be clear that the container 22 will be capable of resiliently-opposed oscillation, from its illustrated attitude, in which the pivots 42 and 43 lie in a common vertical plane, to a limited extent about the axis of the pivotal connection 42. Such movement, of course, facilitates adjustment of the receptacle 24, when in its position illustrated in Fig. '7, to a position of maximum comfort to the occupant of the bed; and further facilitates removal of the receptacle 24 from the container 22 when the assembly is in its lowermost position, as shown in Fig. 1.

As is most clearly apparent from a consideration of Figs. 2 and 3, the sleeve 34 is restrained against axial movement relative to the bar 32 by a collar 5|, abutting one end of said sleeve and adapted to be fixed in an optimum position of adjustment relative to the bar 32 by means of a set screw 52 or the like, and a secon collar 53 abutting the opposite end of the sleeve 34 and similarly adapted to be secured to the bar 32. We prefer to provide spring means of any suitable character tending to hold the container 22 in its uppermost position. One advantageous form of such means is shown in Figs. 2 and 3, but other arrangements for obtaining this effect may be used. As shown, a coiled spring 54 is sleeved on the bar 32, and may, as shown, surround the sleeve 34. One end of said spring is anchored at 55 upon the sleeve 34, and the other end thereof is anchored at 56 upon the collar 53. Because of the fact that the collar 53 may be rotationally adjusted about the axis of the bar 32, it will be obvious that any desired degree of spring force can be applied to the sleeve 34; and preferably the collar 53 will be so adjusted that, when the spring is in equilibrium, the container 22 will be held in the position illustrated in Fig. '7. Otherwise expressed, it may be stated that the spring 54 will be so tensioned that, whenever the sleeve 34 is free to move under the influence of said spring, it will be shifted by the spring into a position in which the container 22 is held in the location of Fig. 7.

An alternative form of container, indicated generally by the reference numeral 22', is shown in Figs. 9 to 11 in association with the arms 35 and 4|. A spring clip 10, which is preferably of the contour illustrated most clearly in Fig. 11, is fixedly supported upon a bar 1| which, in turn, is carried upon a bearing 12 whose opposite ends are provided with trunnion elements 42', 42' pivotally engaged, respectively, with the arms 35, 35'. A lever 73 is welded or otherwise suitably secured to the bearing member 12 intermediate the ends 13126415801", and is pivotally connected to the arm 4| a In this form of the assembly, the "inner receptacle comprises a vessel 24, which may preferably be formed of disposable material, and a nozzle 3| formed to provide a lip 30 similar to the lip 30 of the form illustrated in Figs. 1 to 7, the lower end of the nozzle 3| being snugly receivable in the upper open mouth of the vessel 24; and the spring 10 being engageable with the upper end of the vessel 24, directly in the region receiving the lower end of the nozzle 3| whereby the inner receptacle is supported in the holder 10. The sheath 21 will be assembled with the container 22 in the manner suggested in Fig. 10.

A lever 5'! is fixed to the sleeve 34 and projects radially therefrom, so that said sleeve may be rotationally shifted by actuation of said lever.

A rock shaft 58 is mounted upon the frame in suitable cooperative relation with the lever 51.

As shown, said rock shaft is carried in bearings 59 secured to the longitudinally extending elements of the frame it, and extending transversely across said frame. Alternatively, the rock shaft may be a mere stub suitably supported in any fashion'for oscillation upon an axis parallel to the axis ofthe bar 32. A lever 69 is fixedly associated with the rock shaft 58, and one or more links 5! provide an operative connection between the lever 66 and the lever 51.

In the illustrated embodiment of our invention, the rock shaft 58 extends outwardly beyond one longitudinal element of the frame 50, and its outboard portion is slotted, as at 62, to receive an operating; lever 63 pivotally secured to said rock shaft by a pin 64 traversing the slotted end of said rock shaft. This mounting means permits oscillation of the lever 63 about the axis of the pin 64, while providing an operating connection between said lever and said shaft. A latch plate 65 is secured to the adjacent element of the frame ill and is formed to provide oppositely opening retaining notches 66 and 61. When the lever 63 is engaged in the notch 67, the container 22 is positively held in the position of Fig. '7. Ihe upper end of the lever 63 is disposed in a position wherein it is readily accessible to an occupant of the bed; and it will be obvious that, upon a slight movement of said lever in a counterclockwise direction, as viewed in Fig. 1, the lever will be disengaged from the notch 61, whereafter it may be rocked slightly in a clockwise direction, as viewed in Fig. 2, about the axis of the pin 64, to clear the plate 55. Now, clockwise movement of the lever 53, as viewed in Fig. 1, will turn the sleeve 34 in a clockwise direction to move the arms 35 and 4| in a corresponding direction to draw the container 22 downwardly into the position of Fig. 1. Now, counter-clockwise oscillation of the lever 63 about the axis of the pin 64 will bring said lever into registry with the notch 66, whereupon the lever may be released, and the parts will be held in the positions illustrated in Fig. 1.

Of course, the receptacle 2 may be removed from the receptacle or holder 23 when the parts are in the positions illustrated in Fig.7; or, alternatively, an attendant may separate the fasteners 29 while the parts are in the positions illustrated in Fig. 1, and remove the receptacle 24 Without disturbing the patient.

If, with the parts in the positions of Fig.1, the patient resides to use the bed pan, he merely grasps the lever 63, shifts it slightly in a clockwise direction as viewed in Fig. 1 and then rocks it in a clockwise direction as viewed in Fig. 2, whereupon the spring 54 will lift the container 22 into the position of Fig. '7.

Of course, the usual rubber sheet and the lower bed sheet will be provided with openings registering with the opening I? in the mattress; and, if desired, said sheets may be provided with means, such as separable fasteners, whereby the regions immediately surrounding the openings therethrough may be secured either to the upper surface of the mattress or to the bead 2! of the shield element 20.
