("Cl'. 5`-Ei9`^')v The` invention relatesv toV hospital beds andinas for itsobjectto provide a deviceof. this kindcom pri'sing a head section,` a foot. section. connectedl together by two intermediateA sections., all of. said sections being. hingedly connected and to provide operating means in-l connection with1 a-ll of said sections wherebysaidsections may befplaced in different angular positions in; rela-tionto each other for supporting the; bodyy oi af patient. in various positions for bed. panand treatment operations;

A, further object is to. provide. a hospital bed formed from hingedly connectedf, sections. com.- prisingja body supportinghead section connected together by hingedly connected intermediate-sections and means cooperatng-withall of said. sec.- tions whereby the head and intermediatezsections can be` adjusted` to various angles in relation, to each other. for supporting the bodyfor various purposes and in various positions ior attention and treatment purposes,y or tov incline, the body with the head and foot sectonslin.thesamefplana but in an inclined position. for, instance for. the shock. position, the. Trendellnbergi and the ,Fowler positions,.and atr the Sametime. the iinmediatesections are., inv. formation for forming a, transverse depression in the mattress for. pre.- venting slipping of the body onthebed, and relieving the patient of' any muscular tension.. due to the patientsbody beingin an inclinedposition. This transverse depression,y whereby the, Ipatient is anchored by the buttock fitting, into the. said depression, represents an, entirely new and rad,n ical departure from the Trendellenberg Fowler and postural' drainage positions now obtainable on conventional: beds. With the. patient thus anchored' itis possible to incline the patient' to a greatar angle', thus increasing the (therapeutic) efficiency of the various positions mentioned,l while at` the same time giving the patient a sense of security which will prove valuable in preventing nausea; especially of pa'- tients in a semi-conscious state;

A further object is` to provide a` hospital bed having a relativelylong head sectionto completely support thel bodyv above they buttock and' raise the buttock to a position above an inclined intermediate section so that a bed pan may be easily placediunder'the butto'ck withoutthe-necessity of lifting thepatient.

A, further object is to provide a-v liospitall bed comprising a headsection', twolintermediatesections, and. a foot; section, all* transversely hinged and means whereby all of said sections can be placed4 in the; same plane; or.: ine various' angular positions in relationi to each other.`

A further object'. is: to. provide alhospital# bed comprising a headf section; connected to af foot section, by an; intermediate section and. means whereby the head section may be elevated'. with th'ebacl.r and. head of a patient entirely supported thereon, to a, position where the intermediate section will. incline upwardly towards the. head section, thereby allowing a bed pan to be placed beneath the patient in. a. position. for. use, and at they same. timeobviating the labor involved in lifting the patient, now experienced with conventiona-l hospital beds.. j

A further Objectis to provide.v means whereby the head2 sectionmay be adjusted to various angles,A and independent means whereby the foot section may be adjusted. to various angles.

further object. is to provide the side railsL of the-.bedlwith brackets and tolhingedly connectthe adjacent. endsot the intermediate sectionsto said brackets andi the. outer. ends ofi the. intermediate sections; to` the. head and foot sections, and. to provide` elevating and adjusting meansV for all ofL the various, sections.

further object: is to, provide: downwardly cli*- settransverse braces for thc intermediater sections;`

With; the; above: and other objects in View: the inventionresides inthe combinationand arrange,- ment of. parts as hereinafter set4 forth, shownv in theidrawings. describedl andclaiined, it beingl understood that, changes in-the precise embodiment of. theinvention may be. made. within the scope of what is claimed without departing from the spiritiof the invention.V

The present application is a continuation in part of my application, Serial No. 396,921, led June 6, 1941.

Referring to the drawings, the numeral I designates the head frame of the bed, and 2 the foot frame. The head and foot of the bed are connected together by side rails 3, forming a rigid structure. Secured to the outer sides of the side rails 3 by means of rivets 4 are upwardly extending plates 5. Disposed above the side.rails 3, preferably in registry therewith are the head section G, the intermediate section 1 and the foot section 8 of the adjustable parts of the bed.

The foot section may be formed in two sections, hingedly connected at 9 so a leg adjustment may be obtained and the various positions shown in Figures 'l to 16 inclusive for the purposes hereinafter set forth. The foot end of the intermediate section 1 is hingedly connected at' I0 to one of the ends of the 'plates 5 and adapted to be hingedly moved upwardly to the dotted line position shown in Figure 1, and the fullline position shown in Figure 5 for elevating the section 6, f,

hingedly connected at Il to the end of the section 1. The opposite sides of the intermediate section 1 are connected-together by downwardly arched transverse braces I2, one of which forms the pivotal point IU, and these braces,'in turn, are further braced by longitudinally extending braces I3. Connected t one of the braces I2 at I4 is an operating shaft I which extends to the foot 2 of the bed and has an extensible connection I6 therein. The extensible connection I 6 includes a threaded member carried by the shaft section I5a, and this threaded member is designated by the numeral I1. When the shaft I5a is rotated, a push or pull is imparted to the Shaft I5 for raising or lowering thel intermediate section 1. f

Shaft I5a is rotatably mounted i'n a rock sleeve bearing I8, pvotally mounted at I9 in a bracket carried by the foot 2 of the b ed and terminates in a crank 2 I, adapted to be grasped by the operator for raising or lowering the intermediate section.

The head section, which is hingedly connected at II to the intermediate section 1, is raised or lowered to the proper elevation or inclination by means of rollers 22 engaging the under side of the frame 6, and these rollers are carried by the arms 23 of a U-shaped rock frame 24. The rock frame 24 is pvotally mounted at 25 in downwardly extending brackets 26 carried by the side rails 3 and one of said arms 23 is provided with an upwardly extending plate 21 to which is pvotally connected at 28 a control shaft 29, which shaft extends to the foot of the bed and terminates in an operating crank 3l). Shaft 29 is provided with an extensible connection 3i, similar in construction to the connection I6, therefore it will be seen that by operating cranks 2| and 30 the intermediate and head sections 1 and 6 can be easily and quickly adjusted upwardly or downwardly and the body of the patient can be raised so a ful bed pan can be placed under the buttock. Such a bed pan is disclosed in my application, Serial 396,922, filed June 6, 1941.

A conventional form of mattress 32 rests on the bed sections 5, 1, and 8, and it will be seen that this mattress will conform tothe adjustment of the various sections as clearly shown in Figures 7 to 16 inclusive, and at the same time, with the body of the patient resting on the portion of the mattress carried by the adjustable section 6, the mattress will not become displaced during the body elevating or lowering operation.

After the sections have been properly adjusted as shown in Figure 5, theI bed pan 33 is placed under the butttock 34 of the patient with the extension 35 of the bed pan extending upwardly above the buttock and in close engagement with the mattress 32. It will be seen, during the elevating operation, the weight of the body is mechanically lifted, and it will not be necessary for the nurse to lift the body as is now the common practice when a bed pan is used. l It will be noted that the foot section 8 has hingedly connected thereto at 9, a second foot section 8a, and these sections may be adjusted upwardly by means of a U-shaped frame 34a having arms 35a extending towards the foot 2 of the bed and pvotally connected on the hinging points 9. Where the U-shaped bracket 34a merged into the arms 35a, rollers 36 are provided which have a trackway on the upper sides of the side rails 3 of the bed, and it will be seen that when the U-shaped bracket 34a, Figure 5, is moved in the direction of the arrow a, the hingedly connected portions of the foot sections 8 and 8a will be moved upwardly, therefore it will be seen that a leg adjustment may be obtained when desired. The U-shaped bracket 34a is oper' ated by means of a shaft 31 having an extensible connection therein, designated by the numeral 38, and a similar construction as the connection I 6.

Shaft 31 terminates in a crank 39 at the foot of the bed. It will be noted that the adjustable sections 6,1 and 8 are in registry with the side rails 3 of the bed, therefore it will be seen that it will not be necessary to materially vary the construction of a conventional form ofhospital bed now in use, however applicant does not limit himself to such an application.

The foot section 8a is held and braced in various elevated positions by means of hingedly mounted arms 40 carried by the foot section 8a and which arms are provided with lugs 4I, received between the stop lugs 42 carried by the pivoted bar 43, one end of which is pivoted at 9 and the other end terminates in a traveller sleeve 44, which is slidably mounted on the traveller bar 45 carried by the bed rails 3, therefore it will be seen that the foot section 8a may be held in the vrious raised positions as shown in Figures 10 to 1 Sections 6 and 8a are preferably provided with rollers 46 which ride on the side rails 3. i

Referring to Figures 7 to 16 inclusive, wherein the many desirable positions of the bed are shown, Figure 7 displays and shows the uncomfortable position now commonly in use with bed pans, and it will be obvious with a straight bed it will be necessary for the nurse to lift the body to insert the bed pan 33. With applicants device i the weight of the body is supported and mechaniasraoie Figure 8 shows the normal horizontal position of the bed, with all the sections lowered.

Figure 9 shows the parts of the bed adjusted to semi-Fowler position, a position now obtainable in a standard bed and shows that the new device for which this application is being made does not interfere with this position mechanically.

Figure 10 shows the bed in a position for insertion or removal of a bed pan, also the position available for cleaning of buttock and anal regions. The knees are supported, if desired, by bed clothing tucked under the mattress, which is a matter of nursing technique, and which has been found practical and eiiicient. The insertion of the bed pan is practical in the position shown because of the giving of the mattress and of the muscular portion of the patients buttock, and as the dead weight of the patient is supported above the buttock towards the patients head and on the section B.

Figure 11 shows the bed adjusted and the action of fitting the bed pan 33 to the patient by adjustment of the lower sections 8 and 8a. The

. adjustment of sections 8 and 8a is a manipulation already familiar to the nurse, section 8 being lowered or raised dle 39, while 8a is raised or lowered in relation to section 3 by manual means.

By hingedly moving the sections 8 and 3a of Figure 1l upwardly the bed pan can be forced towards the head section 6, and be securely held in position.

Figure l2 shows the bed adjusted for positioning the patient in the best defecation position with back iraised to maximum position. The patient may be completely relaxed by Placing a pillow under the knees, and bringing up the knee adjusting sections 8 and 8a a little higher.

Figure 13 shows the bed adjusted in a therapeutic position for enema treatments; and the use of a pillow under the knees is desirable for complete relaxation. The complete relaxation of all muscles, plus the gravity coefcient on the descending colon of any patient which is obtainable by lowering the head section 6 yand upperbody of the patient will tend to make all enemas given much more efficient. The complete relaxation of abdominal muscles will enable the patient to retain fluid enemas much more eniciently and easily, and at the same time reducing the necessity of using large amounts of ud for the enema treatment.

Figure 14 shows the bed adjusted for supporting the body in an elevated position for emergency operation, and it will be seen that the patient can be raised or lowered to any level desired with the additional possibility of lowering the upper part of the body to shock position which is highly desirable in most operations.

Figure 15 shows the bed adjusted to full shock position (Trendellenberg). The position is also more efficient for -postural drainage than that obtained on regular Trendelleni'oerg or Fowler beds. This is because of the transverse chamber in which the buttock of the patient is disposed; relieving the patient of any muscular tension, due to the patients body being in an inclined position. A` greater angle of inclination of the patients body is now obtainable, due to this transverse depression anchoring the patient, thus increasing the therapeutic efciency for postural drainage. l

Figure 1,6 shows the bed adjusted in a reverse by means of control hanposition to they full shock shown in Figure 15 and to the full Fowler position, In this position the butto-ck-ts into the central position, and the body is inclined at any angle for postural drainage.

' From the above it will be seen that an adjustable hospital bed is provided which may be easily adjusted for supporting the body of a patient in various positions; for bed pan; therapeutic or operating purposes, and the body is mechanically lifted, thereby obviating the necessity of manually lifting the body, particularly when using a bed pan.
