Claims. (c 5- 90) This invention relates to improvements in 7 invalid and hospital. beds.

It is an object of. the. present. invention. to provide an economical, efficient and. practical invalid or hospital bed. having instrumentalities for permitting the patient to. perform his eliminations without generally disturbing his comforts or his resting position.

A further object of the invention, is to provide a hospital bed with a mattress having a central portion which is readily, conveniently and mechanically removable for substitution by a bed pan mechanically operable for placement thereof for said central portion, when necessary, for use by the patient. I

A further object of the invention is to provide a hospital bed incorporating mechanical fea-- tures for sanitarily introducing into the bed mattress a bed pan for use by the. patient when, desired.

Further objects and advantages of the invention will. appear from the following disclosures thereof together with the attached drawings which. illustrate certain forms. of embodiment thereof. These forms are shown forv the purpose of illustrating the invention since thesame have been found in practise to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangement and organization: of the instrumentalities as herein shown and described.

. Fig.9 is "a partial sectional View of the center 5 portion of the bed shown in Fig. 1-, the bed pan being. shown. inoperative position.

In the drawings which embody a preferred form of the invention, the bed frame [5 is provided with a conventional bed spring l6 having aflat plate ll made preferably'of metal secured at It to the two members l9 and 20 of bed spring l6; Atrthe center of plate l! is a preferably circular opening 21'. A closure or cover 22 is hingedly securedto plate IT at 23 and is held in closed position by a latch 24, which is fulcrumed' at 25 to plate l1 and connected to an operating bar or lever 26 at 21. The latch 24 is provided with a tapered projection 28 to aid in gripping the cover when almost closed and forcing the same intoclosed position.

Cover 22 is operated for swinging movement by means of lever 40' secured to the extension M of the hinge pin 23'. In lieu of a lever 40, a wheel (notshown), may be employed to rotate hinge pin 23. 1

A resilientelement or mattress 3!] has a preferably' circular opening 3!. The wall defining opening 3| is lined and the portion of mattress 3D;adjacent opening 31 is covered with rubberized or other waterproof or non-absorbent material 32. "Stitches- 3 3; secure the material 32 to mattress 3ll.- An upwardly-extending ring or flange 29 which is preferably made apartofcover 22 isused to secure in position a resilient element shelf or support 5| :1 which may be operated up- 7' wardly and downwardly by a lever 52 connected thereto. and fulcrumed at 51 on gusset 52', the latter being secured to frame member 58' by rivets or other suitable means R. Frame members', 58, 58' may be secured to plate IT. A. bar 59 which may form part of frame member 58 has a vertical slot 60- which limits" the up and down movement of shelf 5m. Shelf 51a, is provided with a downwardly-projecting member 5llb which forms at itsv extreme end the arm Me having a pin 5ld made to slide in the slot 5Ie of lever 52. A latch 53 secured to the upper part of frame member 58 keeps the lever 52 in its upper position. Lever 52 when raised places bed pan or chamber 50 in utilizable position as shown in Fig. 9. To place the bed pan in this latter position, latch rod 26 is first pulled outward to release the latch 24; lever 40 is then swung downwardly thus swinging in the same direction cover 22 carrying cushion 34 all as shown in Fig. 9. Bed pan 50 is placed on shelf 5|a. and lever 52 is then swung upwardly until engaging with latch 53. This places the bed pan 5!! in opening 3|. Thus bed pan 5!] replaces cushion 34.

As indicated particularly in Fig. 8, the bed pan 50 is preferably covered with a cushion ring 5| having the depending flange 5|. This'ring comprises the resilient filling 52 covered by a rub berized or other. moisture proof or non-absorbing fabric 53, there being further provided a remov-' able fabric cover 54, which may be secured to the bed pan 50 by means of cords or other flexible elements 55 tied to hooks or loops 56 of the bed pan.

Fig. 6 shows the mattress in a modified form. This mattress has a bottom opening 62 communicating with a reduced top opening 63 formed by the cushion ring 64 secured to the mattress body 30. Within these openings is normally positioned a cushion 34' of similar construction to that of cushion 34. The cushion 34' is drumshaped and of a diameter to fit the reduced opening 63, leaving an annular space 65 surrounding cushion 34'. Cushion 34' is covered with suitable moisture-proof material 35, over which is placed a removable flexible cover 36 made of suitable fabric material and which may be held in place by any suitable means such as, for example, a string-{or cord 36" or by snap fasteners (not shown). In Fig. '7 which is merely diagrammatic, the cushion 34" is shaped to substantially snugly fit both openings 62" and 63". In this case the flange 64" forms an integral portion of the mattress 30". When using the mattress forms shown in Figs. 6 and 7, a bed pan without the padding 5| is preferably employed.

Operation of the device is as follows:

Mattress 3G is covered with regulation bed sheet having a central opening registering with the opening 3] in the mattress. Cushion 35 is normally in position shown in Fig. 1. This cushion 34 is covered with material 35 of similar character as that of the bed sheet (not shown) thereby providing a uniform surface similar to the conventional sick-bed mattress. The shelf 5la. in this case will be in its lowered position as indicated in Fig. 9. If the patient desires to eliminate, the cushion 34 is swung downwardly by means of handle 40 as shown in Fig. 9, the bed pan 50is placed on shelf 5m and the same is then raised until it completely fills the opening 3|. After the elimination has been completed by the patient, the bed pan 50 is lowered on its shelf 5Ia for removal and the hinged cover 22 having the cushion 34 is swung upward and again held in place by means of the latch 24. These operations have been performed without in any way disturbing the patients position which in many forms of diseases, abdominal operations and critical injuries is very undesirable and painful.
