Further, the assembly is designed and constructed to be stable to prevent it from tipping, leaning or becoming unstable while in use. The object of the invention is to allow a patient to be moved simultaneously while emergency medical care is administered.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates generally to the field of stretchers, gurneys and other wheeled supports of patients, and specifically to mobile patient support devices capable of accommodating one or more standing attendants, administering medical care to the patient while being simultaneously transported with the patient to the appropriate treatment area.




2. Description of Related Art




Patient stretchers, gurneys and supports are well known in the art for mobile transport of a medical patient. A bedded horizontal platform may include wheels, swivel and rotatable casters, adjustable height and tilt mechanisms, foot pedals for controlling movement of the patient support surface, push handles for mobility, lifts to elevate and lower the patient support surface, and shrouds for accommodating instruments.




There is a need to safely administer emergency and often life-saving medical care while transporting a patient to another area and with the health care attendant's total devotion to the task of rendering emergency treatment rather than having to be distracted by concentrating on avoiding obstacles in transit and dangerously running alongside the stretcher during the often lengthy encumbered itinerary to the appropriate treatment area. It is usually not medically preferential to delay such care or to perform the life saving/stabilizing medical procedures before transporting the patient to the ultimate treatment destination. For example, in some instances, such as in the case of a patient in cardiac arrest, cardiopulmonary resuscitation (CPR) must be maintained continuously until a heartbeat is restored, and it is not possible to suspend CPR long enough to move the patient more than a few feet. Therefore, when performing CPR, it is not currently possible for the attendants to be mobile.




The present invention solves this problem by allowing the patient to be moved while one or two attendants stand on the mobile platform(s) and administer critical care while the patient is being moved to the appropriate area of treatment. A few minutes saved by the simultaneous rather than sequential administration of these procedures may be the difference in the preserving or losing of human life during some medical emergencies, all while enhancing the safety of the attendant.




A major problem with mobile stretchers or patient transport units on which an attendant could travel with the patient is that the attendant may fall off the stretcher during rapid transit or turning a corner when the attendant's focus is and should be solely on the patient and the rendering of medical care, as opposed to being concerned with maintaining balance and preventing his or her own fall during transit.




Although most prior art stretchers and patient transport units adequately protect the patient from falling or rolling off during transit, the few in which the attendant travels on the stretcher frame with the patient do not provide physical safeguards to the attendant and the platform does not provide adequate space for movement or stability of the attendant. The prior art also does not provide for more than one attendant being able to travel safely with the patient as there are many circumstances in which, for example, a patient needs to receive manual ventilation support in the head region, while I.V. lines and CPR are being administered on the longitudinal side of the patient. Single platform attendant support devices do not adequately solve this problem.




One such wheeled patient support having a platform is disclosed in U.S. Pat. No. 4,190,280 issued to Donohoe in which a platform is secured laterally beyond the periphery of the stretcher in the general body supporting area with a rolling surface mounted to and beneath the platform. In Donohoe, there is only one platform on the side of the patient, and none at the head, and the platform is substantially shorter in length than the length of the patient support surface, has no attached railing to safeguard the attendant from falling during transit, merely mounts to the lower frame, and requires a wheel for support. The assembly must also be stable vertically so that the additional attendant weight on the sides of the assembly do not create center of gravity shifts that could result in the assembly being unstable or tipping over.




BRIEF SUMMARY OF THE INVENTION




A mobile medical patient transport assembly having a patient bed mounted on and above a flat, horizontal, rigid, mobile support frame, with attendant support platforms that are integrated into or extend outwardly from the assembly frame for supporting one or more attendants at the side and/or head of the assembly. Safety rails are provided above the platform to aid the attendants with balance and to prevent them from falling off the platform during transit. This assembly has wheels and a stretcher or mattress so as to support and transport a patient in a supine position along with one or more standing attendants rendering medical care at the side and/or head of the patient without risk of falling off the assembly or tipping over the assembly.




The assembly comprises an upper bed supporting frame and a lower supporting frame connected by vertical supports. Attendant support platforms for supporting one or more attendants on one side or/and at one end of the bed are attached to or emanate from the lower frame. The upper frame has a rigid, planar patient mattress support deck connected to the upper frame, to receive a patient support surface such as a mattress or pad or to allow the patient to be placed directly on the support deck without a mattress or pad.




Four wheels are connected underneath the lower frame so as to be in contact with and for moving the assembly over the floor surface. The wheel(s) at the second end (foot end) of the assembly preferably swivel(s), which permits the assembly to turn corners more easily by reducing the turning radius required, and the two wheels at the first end (head end) of the assembly preferably rotate but do not swivel, allowing circumferential wheel rotation for control. All of the wheels, however, could either swivel or could rotate, depending on preference. In some variations, a single swivel wheel can be used at the second (foot) end to enhance maneuverability.




The two attendant support platforms contained within horizontal and vertical safety railings perpendicularly attached thereto, are integrated into and within the lower frame in one embodiment, or are attached to and emanate from the lower frame in an another embodiment. One attendant support platform is attached laterally on one side of the assembly along the length of the lower frame, and a second attendant support platform can be attached either along the width of the first end of the lower frame portion which is intended to be the end where the patients head lies, or can be attached laterally along the length of the lower frame opposite the other platform. Both attendant support platform sections are positioned well below the patient bed support surface, horizontally above the floor surface and substantially parallel to the floor surface, such that an attendant can stand close to the patient support surface to reach the patient thereon to render medical care while the patient, the attendants and the assembly are being wheeled to an area of treatment.




The attendant support platforms are fixed and integrated into the lower frame of the assembly in one embodiment, and in another embodiment are attached to and protrude from the lower frame assembly, and may be fixed, or retractable or removable for storage or transport through narrow doorways. If retractable, the attendant support platforms can be folded and secured upward, or telescope or slide into the frame employing various methods for doing so. When the attendant support platforms are retractable, the safety railings can also be retracted by folding or collapsing against the sides of the assembly or telescoping into the frame of the assembly. This retracting feature narrows the width and shortens the length of the assembly thereby requiring less space for storage, and permitting the assembly to fit more easily through narrow doorways.




The safety railings are attached to the attendant support platforms and may also be attached to the upper and the lower frame of the assembly, and the vertical support members, and are open at one or both ends to enable entry and exit by the attendants. When open at only one end, the safety railings may also attach to the upper frame and vertical supports. The function of the safety railings is to inhibit falls and enhance the support and balance of the attendants while administering medical care during transport of the patient.




The wheels are attached to the lower frame at the outboard limits of the frame members (corners) to enhance vertical stability to prevent leaning or tipping over with one or two attendants standing on the attendant support platform(s); however, the wheels can be placed at any location provided the assembly is stable. For instance, the attendant support platforms can have swivel wheels or casters attached to the bottom and making contact with the floor, to provide stability for the assembly while accommodating changes in direction of the assembly when it is turning corners or changing directions in confined areas. In other variations, counterweight(s) may be attached within the frame on the side and/or ends opposite the attendant support platforms positioned to counterbalance the weight of the attendant(s).




Each attendant platform section (side or end) can include an upper traction surface to minimize or prevent foot slippage of an attendant, and may be particularly useful during those times when medications and body fluids may be flowing/dripping uncontrollably or inadvertently onto the platforms uppermost surfaces under the attendant's feet.




A pad may be attached to the upper frame above each attendant support platform to provide comfortable padding for the attendants when leaning in to render treatment to the patient.




Guard rails may be included in the vicinity of the patients shoulders and arms to prevent the patients arms from falling off the patient support surface and potentially interfering with the attendant(s) standing on the attendant support platform to the side of the patient.




The primary object of the invention is to provide a wheeled patient transport assembly with a patient supine support surface and one or two platforms with physical safeguards, (i,e safety railings), to safely support and transport a patient and at least one or more medical attendants together with the patient so that the attendant(s) can deliver emergency medical care to the patient while in transit to an appropriate area of treatment while standing on a stable assembly that cannot lean or tip over with attendants standing on board, and while not having to be concerned with their own safety (i.e. falling off the assembly).




In accordance with these and other objects, which will become apparent hereinafter, the instant invention will now be described with particular reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




The Assembly in General




Referring to

FIG. 1

, the invention is shown and comprises a wheeled patient support and transport assembly shown generally at


10


having an elongated horizontal, rigid lower frame


11


, a first end


23


, a second end


25


, and first and second elongated sides


27


and


29


respectively. Rigid vertical supports


16


or other similar mechanisms known in the art are used for positioning and supporting the upper frame


12


above the lower frame


11


. While four vertical supports


16


are preferred, more or less than four vertical supports


16


can be used, for example as shown in

FIG. 1A

, or the upper frame


12


can be attached to an assembly or mechanism that allows the height of the upper frame


12


and patient support deck


17


to be elevated or lowered as shown in

FIG. 1G

, or the upper frame can be attached to the lower frame by two strategically place vertical support members a as shown in an alternate embodiment in

FIG. 4C

in which the two vertical support members


16


can either be fixed, or can be vertically adjustable by electrical, hydraulic, mechanical or other means to allow the upper frame


12


and patient support deck


17


to be elevated or lowered to the desired height.




Any other means can be used to attach the upper frame


12


and patient support deck


17


to the lower frame


11


provided they are stable, securely attached and can support the weight of the patient and the stress forces exerted by the attendants while administering treatment to the patient.




The patient support and transport assembly


10


is essentially rectangular and shaped like a bed for patient support and transport. The rigid, planar patient support deck


17


can include a padded patient support surface


18


that rests on the patient support deck


17


, or the patient can be placed directly on the patient support deck


17


. In this preferred embodiment, the upper frame


12


and patient support deck


17


extend from the vertical supports


16


, and are shorter in length and narrower in width than the lower frame


11


of the assembly by approximately the same or similar width as the attendant support platforms


20


and


22


so that the lower frame


11


extends beyond the periphery of the upper frame


12


and patient support deck


17


on the end and side where the attendant support platforms


20


and


22


are located. However, the correlation between the dimensions of the upper frame


12


and lower frame


11


can be different as shown in

FIGS. 4B and 4C

, such correlation being irrelevant so long as the assembly


10


is stable.




Likewise, the assembly


10


can be constructed in various configurations using various combinations of the features as described herein so long as the assembly


10


is stable and can perform its intended function.




Attendant Support Platforms




Along the first elongated side


27


, of the assembly


10


there is a first rigid attendant support platform


20


at the first elongated side located in general proximity to the patients upper body and torso area, and a second attendant support platform


22


along the first end


23


in general proximity to the patients head area of the mattress surface


18


. In this preferred embodiment, the two attendant support platforms


20


and


22


are preferably contained within the lower frame


11


at the first elongated side


27


and at the first end


23


and are shaped and constructed to accommodate the weight and physical dimensions of one or two adult attendants.




Each attendant support platform


20


and


22


can occupy the entire length and width of the first elongated side


27


and first end


23


respectively as shown in

FIGS. 1 and 1A

, or occupy only a portion of the length and width of the first elongated side


27


and first end


23


similar to that shown in FIG.


1


B. The attendant support platforms


20


and


22


can be connected to each other as shown in

FIGS. 1 and 1A

, or detached from each other as shown in FIG.


1


B.




The attendant support platform sections


20


and


22


can end at the outside perimeter of the upper frame


12


as in

FIGS. 1 and 1B

, or can extend underneath the outside perimeter of the upper frame


12


similar to that shown in

FIG. 1A

thereby providing extra toe/foot room for the attendants.




The attendant support platform


20


can be placed on the second elongated side


29


as shown from a top view in

FIG. 1C-1

, in which case the upper frame


12


, patient support deck


17


and vertical supports


16


are placed such that edges of the first elongated side


27


of the upper frame


12


and patient support deck


17


are in line and even with, or contained within the edges of the lower frame


11


on the first elongated side


27


underneath the patient support deck


17


. The attendant support platforms


20


and


22


may also be placed opposite each other and occupy part or all of both elongated sides


27


and


29


as shown from a top view in

FIG. 1C-2

.




The upper surface of the attendant support platforms


20


and


22


can be exposed, or a tread or friction-inducing surface


54


can be added to provide traction for and prevent slippage of the attendant(s).




A pad


55


as shown in

FIGS. 1 and 1A

can be attached to the upper frame


12


above each attendant support platform


20


and


22


to provide comfortable padding for the attendant(s) when leaning in to render treatment to the patient, or there can be no padding as shown in FIG.


1


B.




In some instances, it may be desirable to have a mechanism for adjusting the height of the upper frame


12


and patient support deck


17


as shown in FIG.


1


H.




In other instances where space is limited, it may be desirable to have only one attendant support platform


20


as shown in FIG.


1


I. In this embodiment, the attendant support platform


20


is sufficiently wide and long to accommodate two adult attendants, and is placed along the first or second elongated side


27


or


29


in a position that allows one attendant access to a patients head area and the other attendant access to the patients upper torso area so both attendants can simultaneously administer treatment to the patient.




Safety Railings




Each attendant support platform


20


and


22


includes safety railings


30


attached at one or more areas to the lower and upper frames


11


and


12


and to the vertical supports


16


and the attendant support platforms


20


and


22


along the outermost longitudinal edge of the attendant support platforms


20


and


22


. The safety railings


30


are affixed in such a manner, welded, bolted, screwed, as to withstand the weight of the attendants leaning, falling, or otherwise safely supported by the safety railings


30


. The safety railings


30


can extend for the partial length of the attendant support platforms


20


and


22


as shown in

FIGS. 1

, and


1


A, or can extend for the entire length of the attendant support platforms


20


and


22


as shown in FIG.


1


B. To allow for ingress and egress of the attendants, the safety railings


30


can be open at only one end as shown in

FIGS. 1

,


1


A, and


1


B, or can be open at both ends as shown in FIG.


1


D. The safety railings


30


can be comprised of relatively simple configuration similar to that shown in

FIG. 1D

, or more complex configurations similar to that shown in

FIGS. 1

,


1


A,


1


B, and


1


E.




The safety railings


30


function to protect the attendant(s) from falling and provide an area of balance for the attendant during transport and/or while administering treatment. The safety railings


30


are particularly important during conditions of emergency where rapid transport is desirable and the attendants must devote full concentration and attention to the patient without being unduly distracted by concerns for their own safety.




While safety railings


30


are the preferred means for preventing the attendants from falling off the attendant support platforms, belts, restraints, brackets, supports, braces or other means can be employed for this purpose.




Guard Rails




In both the preferred and alternate embodiments and variations thereof, two guard rails


56


can be attached to the upper frame


12


of the assembly


10


along the two elongated sides


27


and


29


in the vicinity of the patient's shoulders and arms as shown in FIG.


1


A. The purpose of these guard rails


56


is to prevent the patient's arms from extending beyond the periphery of the upper frame


12


so that the patient's arms cannot interfere with the attendants. The guard rails


56


protrude above the patient support deck


17


and patient support surface


18


sufficiently to contain the patient's arms within the confines of the upper frame


12


, but not extend so far as to interfere with the attendant. The guard rails


56


can be particularly useful when the assembly is constructed in a narrow fashion for use in environments where space is limited or doorways are narrow. The guard rails


56


when included in the assembly


10


can either be fixed or detachable, or can be attached to the upper frame


12


so the guard rails collapse or fold out of the way. The guard rails


56


can be composed of a series of rails as shown on the first elongated side


27


in

FIG. 1A

, or a solid piece of material as shown on the second elongated side


29


in FIG.


1


A. If necessary when there is padding


55


attached to the upper frame


12


, then this padding


55


is molded or contoured around the area where the guard rails


56


attach to the upper frame


12


.




Wheels




The wheels


44


and


48


, two of which


44


are at the first end


23


of the assembly


10


, and two of which


48


are at the second end


25


of the assembly


10


, are mounted beneath the lower frame


11


either underneath the four corners, underneath the vertical supports


16


or in close proximity to the four corners of the lower frame


11


as shown in

FIGS. 1

,


1


A,


1


B,


1


C-


1


,


1


C-


2


,


1


D,


1


E,


1


F and


1


I; or within the confines of the lower frame


11


away from the outer edges of the lower frame


11


as shown in

FIGS. 1G and 1H

, which gives more foot clearance to the attendants pushing and/or standing around the assembly, or accommodates a mechanism for elevating or lowering the upper frame


12


and patient support surface


17


as shown in FIG.


1


H. Regardless of the configuration or the number of wheels


44


and


48


, the wheels


44


and


48


extend downward to contact the floor surface


15


. The wheel(s)


48


at the second end


25


of the assembly


10


preferably swivel so as to permit the assembly


10


to turn corners more easily by reducing the turning radius required. The wheels


44


at the first end


23


of the assembly


10


preferably are such as to allow only circumferential wheel rotation for control, however, any sturdy, easy to roll wheel can be used at either end


23


and


25


. The wheel location is important to ensure vertical stability of the assembly during transit. Strategically place weights


90


can also be employed for stability as shown in

FIGS. 10A and 10B

.




While four wheels


44


and


48


placed in the four corners of the assembly


10


are the preferred means for moving the assembly


10


across the floor surface


15


, any number of wheels or any other means such as castors, bearings, pads or skids composed of metal or a low friction material such as Teflon, nylon or similar materials, air pressure or other means that allow the assembly to be easily moved across the floor surface


15


can be employed, and they can be placed at any position on the lower frame provided that the assembly


10


is vertically stable and does not tip, lean or fall over.




Construction




The assembly


10


lower frame


11


and upper frame


12


, structural and vertical support frame members


16


, attendant support platforms


20


and


22


, safety railings


20


and guard rails


56


are preferably constructed of tubular steel, aluminum, or any durable material customarily used for stretchers, gurneys, carts, and hospital beds; however, the frame vertical support members can be constructed of any durable, sturdy material capable of supporting the weight of a patient and the attendants while still being relatively easily movable for transport of all persons to another location by a person or persons pushing or pulling the assembly along the floor surface


15


. When constructed of metal, the assembly


10


, lower frame


11


and upper frame


12


, structural and support frame members


16


can be connected by welding the respective connecting ends together in the conventional way, however, screws, bolts, or other conventional fasteners can be utilized, particularly when the frame supports, beams, platforms, and sides are constructed of wood or PVC. Regardless of the construction materials selected, the assembly


10


must be strong and durable enough to withstand the weights of the patient and attendants and the stress forces imparted on the assembly


10


during transport, including impact with walls and other devices encountered during emergency transport of the patient and attendants.




PURPOSE AND FUNCTION OF THE INVENTION




The purpose of the instant invention is to enable emergency transport of patients in critical medical crises to an appropriate area of treatment like an operating room while one or more medical attendants simultaneously administer medical treatment during transport without the assembly leaning, tipping over or otherwise becoming unstable. Accordingly, the duration of each use is likely to be brief. The patient will be placed on the assembly


10


, moved to the appropriate area of treatment and removed from the assembly


10


upon arrival. Therefore, the design and structure of the assembly


10


need only be very basic; however, additional features as discussed throughout can be included to enhance the invention.

30


that has no vertical members, this configuration can also be constructed with a safety railing that has a vertical member


30




a


as shown in FIGS.


7


D


3


and


7


D


4


. In FIG.


7


E


1


the safety railings and attendant support platforms are constructed and attached to the assembly


10


they can be detached from the assembly


10


for storage purposes. Releasable mechanisms are used to hold the safety railings


30


and attendant support platforms


20


and


22


in place while in use, and to facilitate easy removal. While FIG.


7


E


1


illustrates one method of attaching and removing the attendant support platforms


20


and


22


and safety railings


30


, many other methods can be utilized for this purpose.




While the methods shown in the

FIG. 7

series and discussed above are the preferred methods for disposing the attendant support platforms


20


and


22


and safety railings


30


to save space for storage of the assembly, any means of folding, hinging, telescoping, retracting or removal can be employed for this purpose.





FIGS. 8A and 8B

show alternate embodiments where the assembly has two first end


23


preferably rotatable wheels


44


and only one at the second end


25


preferably swivelable wheel


49


.




Vertical stability of the assembly is critical to safe operation and use. Therefore, in addition to or in place of constructing the assembly


10


to be stable, other methods for supporting or offsetting the weight of the attendants and enhancing vertical stability of the assembly can be added to the attendant support platforms or built into the assembly. The following

FIGS. 9 and 10

series illustrate methods for accomplishing this objective.




In

FIG. 9

, one or more swivel wheels and supports assemblies


35


can be added to the bottom of the attendant support platforms


20


and


22


for weight and balance reinforcement to support the weight of the attendants and provide vertical stability for the assembly. These swivel wheels can be fixed as shown in

FIG. 9

, or in embodiments where the attendant support platforms telescope or fold, a spring-like, friction-engaged button


39


and corresponding opening


38


on the wheel bracket


37


activates both the retraction and downward in-use placement position of the swivel wheel


36


as shown in FIG.


9


A. This spring-actuated friction button is well-known in the art, operates easily for manual activation, and is a simplified, space-saving construction.




While swivel wheel assemblies


35


are the preferred means for placing under the attendant support platforms


20


and


22


for providing weight reinforcement and enhancing the stability, any means that will move freely across the floor surface while supporting the attendant support platforms


20


and


22


, including castors or skid pads can be utilized for this purpose.




Another method to offset the weight of the attendants and enhance vertical stability is to employ one or more counter weights


90


as shown in

FIG. 10A

(side view) and


10


B (bottom view). Ideally, these counter weights should be constructed of lead, iron or steel, although any other heavy metal or material such as concrete can be used. They can be attached or built into the lower frame or other parts of the assembly in strategically placed locations where they will help to offset the weight of the attendant(s) standing on the attendant support platforms


20


and


22


.




In the alternate embodiments in which the attendant support platforms and safety railings collapse, fold, telescope or otherwise retract, the vertical support railings can also collapse or fold so that the upper and lower frames can be brought together in a manner like or similar to an ambulatory stretcher used in ambulances where the upper frame and patient support surface can be raised or lowered from the lower frame.

FIGS. 11A and 11B

show a variation of the invention so constructed

FIGS. 11C and 11D

show a different method for collapsing the structure. In the variation shown in

FIG. 9

, swivel wheels have been employed underneath the attendant support platforms


20


and


22


for stability; however, other methods as discussed throughout can be employed for this purpose.




While attendant support platforms like those shown as


20


and


22


throughout the figures and safety railings like those shown as


30


throughout the figures are the preferred method for supporting the attendants and preventing them from falling, other means can also be utilized for this purpose.

FIG. 12

shows two such means. Along the first side


27


, an attendant support platform


20


with built-in footholds


95


that is just large enough to accommodate one attendants feet is attached to the lower frame


11


. A safety rail


30


protrudes from the upper frame and is connected to the attendant support platform


20


by a vertical member


30




b


, which can also be located at the outboard corner shown as


30




c


in phantom. The attendant support platform


20


and safety railing


30


can be fixed in a stationary position so the attendant can stand adjacent to the patients upper torso (in which case the vertical member


30




b


can be eliminated), or they can slide back and forth along the upper frame


12


and lower frame


11


. Various means for sliding a part along a horizontal member are well known in the art and need not be discussed in detail here. When such sliding means are employed, means for preventing the attendant support platform


20


and/or footholds


95


and safety railing


30


from moving while in use need to be employed. Such means are also well known in the art and need not be discussed further here. In other configurations not shown here, footholds


95


alone can be utilized in place of the attendant support platform


20


with integrated footholds


95


, or a small attendant support platform without footholds


95


can be utilized as well. In other configurations the vertical member


30




b


connecting the safety railing


30


and attendant support platform


20


or footholds


95


can be eliminated so the two slide along the upper frame


12


and lower frame


11


independently. Also shown in

FIG. 12

at the first end


23


of the assembly


10


is a different means of supporting and securing the attendant. A small attendant support platform


22


is attached to the lower frame. This attendant support platform


22


has raised edges around the three outboard sides to prevent the attendants feet from moving beyond the edge, thereby preventing the attendants feet from coming off the attendant support platform while the assembly is in use. A strap or metal restraint


96


takes the place of a safety railing and is fixed to one point on the upper frame


12


, and can be clipped or otherwise attached to another point on the upper frame


12


. The attendant can then step onto the attendant support platform


22


, wrap the restraint


96


around his or her body, and attach it to the upper frame


12


. Like the safety railings


30


shown throughout, the restraint


96


is used to provide a point of balance for the attendant and keep the attendant from falling off the assembly


10


while it is in use. This restraint


96


can take various forms, including that of a harness, belt, strap or other means of restraint, all of which can be used to keep the attendant from falling.




Referring to the preferred embodiment in

FIG. 3

, in the practice of this invention, when an emergency condition arises which necessitates a patient being quickly stabilized and simultaneously moved to an area of treatment, as in moving an arrested patient to surgery while simultaneously performing CPR, the patient


60


is placed on the horizontal patient support deck


17


or patient support surface


18


of the assembly


10


while one or more medical attendants


65


stand on the attendant support platforms


20


and


22


disposed in a position for rendering emergency treatment. Such emergency treatment, e.g., bagging, inserting of IV lines, administering CPR can be performed by the attendant(s)


65


standing on the attendant support platform(s)


20


and


22


and the patient


60


can be moved simultaneously and without interruption of emergency and potentially life-saving treatment, while being wheeled by one or more other attendants (not standing on a platform and not shown in the drawings) to the desired area of treatment such as an operating room. Upon arrival, the patient


60


can be treated on the assembly


10


, but in most instances will be removed from the assembly


10


and placed on an appropriate surface like an operating table for continued emergency treatment. For example, with the instant invention, patients that could not otherwise be moved at the time, (e.g., a situation in which emergency treatment cannot be stopped for more than a few seconds such as with a patient in cardiac arrest, or severe trauma), can be taken to the desired area of treatment without undue delay and simultaneous with the administration of CPR or other potentially life saving emergency treatment. In addition to the benefits to the patient


60


, the attendants


65


treating the patient


60


during this wheeling need not be concerned with running alongside the assembly, nor with avoiding or encountering floor or hallway obstacles, nor are the attendants exposed to great risk of falling from or slipping on the platforms on which they stand due to the existence of the safety railings


30


, and the attendants can continue to render treatment (such as CPR) which could not be continued if the attendants had to run alongside the patient as on conventional stretchers. Accordingly, an attendant


65


standing at the head or alongside of the patient


60


will be able to devote substantially his or her entire attention to treating the patient


60


while one or more other attendants need only be concerned with quickly pushing, pulling and steering the assembly


10


to the appropriate area of treatment. The patient


65


is treated during transport rather than prior to transport to the ultimate treatment destination, (e.g., operating room), saving valuable and potentially life-saving minutes in the process. In addition, in a number of variations, the attendant support platforms and safety railings may be retracted by various means to be stored when not in use, thereby saving space. A number of desirable features can be added, for example a traction surface


54


on the upper surface of the attendant support platforms to help prevent slippage of the attendants, padding


55


to provide comfort for the attendants, guard rails


56


to prevent the patients arms from falling off the patient support deck


17


or patient support surface


18


thereby preventing the patients arms from interfering with the attendant. Additional features like mechanisms for adjusting the height of the upper frame


12


, patient support deck


17


and patient support surface


18


can be added as shown in

FIGS. 1G

and


4


C can be built into the assembly, and steering handles


97


and IV poles


98


can be added as shown in FIG.


4


C. The instant invention can be constructed with any number or combinations of features and configurations as discussed herein.




The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiments, with configurations and features that are believed to be useful. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
