G. COBB lApril 22, 1958 BEDSTEAD ATTACHED CERVICAL TRACTION MEANS Filed Nov. 25, 1955 GEORGE CQBB W *Kga/vzw l ATTQELNEYS United States Patent O M' BEDSTEAD ATTACHED CERVICAL TRACTION NIEANS George Cobb, Burlingame, Calif. Application November 25, 1955, Serial No. 548,946 Claims. (Cl. 12S-84) This invention relates to traction devices, and more particularly has reference to traction apparatus usable to particular advantage on hospital beds of the type having portions supporting the head of the patient which portions are vertically swingable to selected positions of adjustment, so that the patient can be supported either in a fully prone position or alternatively, in any of various seated positions.
Ordinarily, cervical or neck traction devices are so designed that the line of pull along which the tractive force is exerted will change whenever the patient is adjusted between prone and seated positions, unless corresponding adjustments of the associated weights are effected. Usually, it is'necessary to restring or reposition the weights to produce the proper angle, vwhen the hospital bed is adjusted for changing the patients position and this, of course, is a time-consuming practice, sometimes involving in addition considerable discomfort so far as the patient is concerned.
Heretofore, cervical traction devices of which I have knowledge have not been adapted to automatically retain the proper angle between the line of force along which the traction is exerted and the plane of the portion of the mattress frame on which the head of the patient is supported, during adjustment of said portion of the mattress frame. The main object of the present invention, accordingly, is to provide a generally improved cervical traction device that will retain said angle regardless of the position to which the associated portion of the bed frame is swing` ably adjusted.
Another object of importance is to provide a traction device of the character referred to so designed that said angle will be maintained, in selected positions to which the hospital bed is adjusted for changing the elevation of the patients head, without making it necessary to restring or reposition the weight.
Another object is to provide a cervical traction device as stated which will exert the same amount of pull upon the patient in all positions to which the head-supporting portion of the mattress frame is adjusted.
Still another object of importance is to provide a cervi cal traction device as stated which will be designed to particularly facilitate the adjustment of the angle between the line of pulling force and the plane of the associated part of the mattress frame, with a minimum amount of diiculty.
Yet another object is to provide a cervical traction device as described which can be used with any of various conventional hospital beds or equivalent patient-supporting means, without requiring modification or redesign of said beds or other supports.
Still another object of importance is to form the cervical traction device in such a manner as to facilitaterits swift attachment to or detachment from the associated support.
A further object of importance is to provide a cervical traction device as stated which will be of simple construction, will be rugged, and will nevertheless be fully 2,831,482 Patented Apr. v22, 1958 elicient under all circumstances, despite the relatively low cost of the construction.
Other objects will appear from the following description, the claims appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, and wherein:
` Figure l is a view of a hospital bed partly in side elevation and partly. in longitudinal section, the traction device constituting the present inventionbeing shown in side elevation attached to said bed, the device and bed being shown in full lines with the patient supported in a prone position, and in dotted lines with the patient supported in an inclined or semi-sitting position;
' Figure 2 is a perspective view of the cervical traction device per se;
Figure 3 is a rear perspective view of the cervical traction device per se; and
Figure 4 is an enlarged transverse sectional view through said device taken on line 4 4 of Figure 3.
The reference numeral 10 generally designates a conventional hospital bed having a main frame 12 on which is supported an adjustable frame 14l swingable about a horizontal axis extending transversely of the bed and supporting the mattress and spring on which the patient lies. The frame 14 can be adjusted to a horizontal position shown in full lines in Figure 1, and in this position a patient will be fully prone. Alternatively, the adjustable frame 14 can be adjusted upwardly, as for example to the dotted line position of Figure l, 'so as to dispose the patient in a full or semi-sitting position.
The cervical traction device constituting the present invention has been generally designated at 16, andas distinguished from prior similar devices of which I have knowledge, is attached directly to the vertically swingable frame 14. The device includes a base bar 18, to the rear surface of which is iixedly secured a back plate 20 extending below the bottom surface of the base bar so as to cooperate therewith in forming a downwardly opening, angular recess receiving the end cross bar of the frame 14.
Projecting from the bottom edge of the ilange dened by plate 20 are brackets 22, and threadable vertically in said brackets are clamp screws 24. The brackets 22 extend below the bottom bar 18 of the device, and are capable of being turned upwardly against the cross bar of frame 14, with said end cross bar seated in the angular recess defined at the base of the device. In this way, the frame of the device is lxedly but removably secured to the outer end of the vertically adjustable bed frame 14, and is disposed in a plane normal to that of the frame 14.
Fixedly secured at their lower ends to the midlength portion of the base bar 18 are upwardly projecting standyards 26. These are spaced laterally of one another,
and at their upper ends are xedly connected by a cap plate 28.
The standards 26 are braced in their upright positions by inclined, upwardly converging brace bars 30, xedly connected between the outer ends of the base bar 18 and the intermediate portions of the respective standards.
The standards delne between them a vertical slot 31, and rotatably mounted in said slot are pulleys 32. The pulleys are spaced uniformly longitudinally of the standards 26, for use of any selected pulley in obtaining a proper angle along which the line of force is t0 be exerted by the traction device.
Trained about a selected one of the pulleys 32 is a flexible element 34 such as a rope, andconnected to one end of saidexible element is a weight 36. A Llshaped guide 3S is lixedly secured to and projects rearwardly from the base of the device, and rotatably mounted in the `guide 38 is a pulley 4t) overwhich the flexible element is trained.
Connected to the other end of the exible elementris an eye` 42 vformed medially between the opposite ends of a connecting rod or cross bar-14 the ends of which are formed with hook-like or U-shaped extensionsl do, A neck strap or harness generally designated at 48, which per se is of conventional form, has its ends attached to the extensions 46.
In use of the device, the same is clamped to the frame 14 at the outer end of the frame,`in a plane normal to that of the lframe and paralleling the pivot axis 56 of the frame. The llexible ,element is trained over a selected pulley 32, and is attached to the neck strap 43. The weight 36 is attached to kthe other end of the exible element, after said element has been trained through the guide 38 about pulley 40. Guide 38, as will be understood, prevents the ilexible element from jumping o the pulley 49 during vertical adjustment of the frame 14.
It will be understood that the purpose of the several pulleys 32 is to permit the tlexible element to extend from the standards 26 to the neck strap at a selected angle relative to the plane of the frame 14. Said angle will be selected, of course, according to the particular lines along which the tractive force is to befexerted.
With the device operatively associated With the neck strap and trarne in the manner shown in Figure 1, the above mentioned angle will not be changed regardless of the position to which the frame 1d is adjusted about its pivot axis 50. Thus, by comparing the full and dotted line showings of Figure l, it will be seen that the angle remains unchanged in both of the'two illustrated positions of the frame. In one of said positions the patient is fully prone, and in the other position the patient is in a semi-sitting position.
Swingable adjustment of the frame 14 upwardly from the dotted line position, to dispose the patient in a full sitting position, will still not have the effect of changing the angle in any way, and as will be understood, it
is not necessary to reposition the weight or otherwise adjust the device under these circumstances. The only time when repositioning of the flexible element or Weights is necessary will be that occurring when it is necessary to change the angle or line of force along which the traction is to be exerted, and this of course has nothing to do with the swingable adjustment of the frame 14.
lt is believed apparent that the invention is not necessarily conned to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specic construction illustrated and described, since such construction is only intended to be illustrative of the principles of operation and the means presently devised to carry out said principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended calims.
