Description




BACKGROUND AND SUMMARY OF THE INVENTION




The present invention relates to medical stretchers, and particularly to stretchers used for patients requiring treatment or examination of the pelvic region, such as during labor and delivery or during gynecological examinations. More particularly, the present invention relates to stretchers convertible between a conventional stretcher configuration that supports the patient in a recumbent position and an Ob/Gyn configuration that supports the patient in a parturition or lithotomy position while providing medical caregivers improved patient access.




Hospital emergency rooms and maternity units often receive patients that require handling in both a recumbent position and in a parturition or lithotomy position. For example, a maternity patient will typically remain in a recumbent position during labor, with her legs resting on a mattress surface, and then assume a parturition or lithotomy position to facilitate childbirth. During labor there often is also a need for the medical caregiver, such as a nurse or doctor, to have access to the patient's pelvic region, for example to assess cervical dilatation, after which time the patient again assumes a recumbent position. Patients and care givers thus benefit from medical stretchers that both allows the patient to lie in a conventional, recumbent position and that convert to a configuration to support the patient in a parturition or lithotomy position while simultaneously providing the care giver with improved access to the patient's pelvic region.




According to one aspect of the present invention, a patient support apparatus includes a base, a frame coupled to the base, and a deck coupled to the frame. The frame includes a storage portion.

support the bottom of center leg supports


17


,


117


when in the conventional stretcher configuration and, as discussed below, facilitate moving center leg supports


17


,


117


between the conventional stretcher configuration and the stowed configuration.




Center leg supports


17


,


117


illustratively include a bottom U-shaped rod


84


configured to define a rod pocket


86


between rod


84


and the bottom of center leg support

when center leg support


17


is moved from a stowed position to a conventional stretcher position. Outer guides


171


engage outer portions of the pivot blocks


82


to align the center leg support


117


relative to the frame


14


. Rod


84


engages stops


88


when the


117


leg support is moved fully toward the foot end of frame


14


. Center leg support


117


is then pivoted around pivot blocks


82


until latch pins


168


engage apertures


70


of frame


14


. Center leg support


17


includes similar support surfaces


79


and ramp surfaces


73


for engaging pivot blocks


82


as shown in

FIGS. 3-5

.




Referring now to

FIG. 3

, when center leg support


17


is unlatched from deck


14


by pulling handle


64


in direction


72


to retract pins


68


, the foot end of center leg support


17


can be rotated upwardly in direction


90


so that the opposite end rotates downwardly in direction


92


as center leg support


17


rotates about pivot blocks


82


. A storage cavity


94


configured to receive center leg support


17


is defined between deck


16


and frame


14


. After rotating center leg support


17


about pins


88


, center leg support


17


can be moved as shown by arrows


96


,


98


in

FIG. 3

to its stowed position within cavity


94


as shown in FIG.


4


. Although the illustrated embodiments employ pivot blocks


82


and rod


84


, it is understood that other suitable mechanisms can be used to facilitate moving center leg support


17


between the conventional stretcher and stowed configurations.




Center leg support


17


,


117


is moved from the stowed configuration to the conventional stretcher configuration by reversing the above-described steps. In this sequence, pivot blocks


82


guide movement of center leg support


17


,


117


and also provide a stop to prevent center leg support


17


from being pulled out past the point where it is rotated into the conventional stretcher configuration. This stop function is accomplished when pins


88


engage rod


84


to stop center leg support


17


from extending past the point at which it is rotated back up to couple to deck


16


in the conventional stretcher configuration.




Deck release mechanism


40


illustratively is a cable-actuated mechanism and includes a lever


102


coupled to each of the deck outer leg sections


24


,


26


as best shown in the view of right outer leg deck section


26


in FIG.


6


. As discussed in more detail below, a second cable-actuated mechanism coupled to levers


102


also enables horizontal rotation in hinge assembly


30


of outer leg deck sections


24


,


26


.




Outer leg deck sections


24


,


26


include gripping handles


104


that are coupled to deck sections


24


,


26


. Gripping handles


104


and levers


102


provide an ergonomic mechanism that allows an operator to actuate levers


102


while gripping handles


104


. Pulling each lever


102


enables horizontal rotation of a respective one of outer leg deck sections


24


,


26


about pivot connection


124


by releasing a mechanical lock


128


and also retracts a frame latching pin


106


. When both levers


102


are pulled simultaneously, both frame latching pins


106


are retracted from apertures in the frame


14


, and deck


16


can be moved longitudinally relative to frame


14


in the direction of arrow


103


as shown for example in FIG.


7


. As discussed above, rollers


34


roll in channels


36


,


38


as the deck


16


moves relative to the frame


14


. Since both levers


102


adjacent handles


104


of outer leg deck sections


24


,


26


must be activated to release the deck


16


, a caregiver must be positioned at a foot end


56


of stretcher


10


to release the deck


16


. This positioning of the caregiver provides improved control for movement of the deck


16


.




It is understood that levers


102


can be replaced by other suitable mechanisms, such as a single button or two buttons that perform the functions of enabling horizontal rotation of outer leg deck sections


24


,


26


and horizontal movement of deck


16


relative to frame


14


. Furthermore, although center leg support


17


in the illustrated embodiment prevents deck


16


from moving toward foot end


56


when stretcher


10


is in the conventional stretcher configuration, it is understood that alternative leg supports could be coupled to deck


16


to allow such movement.




Each lever


102


is coupled to a control cable


108


that is coupled to frame latching pin


106


. Frame latching pins


106


are each mounted to a bracket


110


that is coupled to an inside wall


112


of deck carriage plate


32


so that latching pins


106


and brackets


110


move along with deck


16


relative to frame


14


. Latching pins


106


are configured to enter holes (not shown) in channels


36


,


38


to latch deck


16


in first and second predefined positions relative to frame


14


. Pins


106


lock in a first pair of apertures in channels


36


,


38


when the deck


16


is in a conventional stretcher position of FIG.


1


. Pins


106


lock in a second pair of apertures formed in channels


36


,


38


when the deck


16


is rolled to its examination position shown in FIG.


7


. When lever


102


is pulled, cable


108


releases the pin


106


from the channel


36


or


38


allowing the deck


16


to move relative to the frame


14


. It is understood that other suitable mechanisms can be provided, such as a latching mechanism that provides for infinite longitudinal adjustment instead of predefined positions defined by holes in channels


36


,


38


.

moves back and forth within the cylinder


128


of the mechanical lock when an actuator


127


is released by control wire


109


when lever


102


is pulled. When lever


102


is released, the actuator holds the rod


125


in a locked position relative to cylinder


128


. An end of rod


125


is pivotably coupled to a flange of bracket


118


by pivot pin


129


as best shown in

FIGS. 12 and 13

. It is understood that other mechanisms for hinge assembly


30


can be provided, such as a single universal joint with a single actuation and latching mechanism for enabling rotation about two or more axes.




Outer leg sections


24


,


26


are surrounded by a flexible covering


132


that includes a generally bellows-shaped section


133


located over hinge assembly


30


. Bellows


133


therefore permits pivotable movement of the leg sections


24


,


26


. Covering


132


also surrounds actuator


122


as best shown in FIG.


12


. Covering


132


is illustratively formed from a rubber material, although it is understood that any suitable covering may be used. Covering


132


facilitates cleaning of the outer leg sections

and socket


152


provide for dual axis rotational adjustment of support tray


136


in directions


156


,


158


. Furthermore, rotation of mounting shaft


146


in direction


160


combined with offset arm


150


provides for a wide range of horizontal adjustment of calf support


134


. When not in use, calf supports


134


are stored in a pair of storage receptacles


135


in frame


14


as shown in FIG.


14


. Receptacles


135


are formed from openings

54


and a fiber-optic supply link coupled between cable


192


and source


196


. The light source


196


may also be coupled to the deck


16


or base


12


. It is understood that other suitable light systems can be used for light system


190


, and that it can be attached or incorporated into frame


14


as desired. Stretcher


10


can be wheeled from place to place within a hospital or other facility. A particular room may not have adequate lighting for the stretcher


10


. Since the light system


190


is incorporated into the frame of the stretcher


10


, a suitable light source for examination is always available regardless of the location of the stretcher


10


.




The light source


196


includes a power cord (not shown) configured to be coupled to a power outlet of a wall. The light source


196


is coupled to the base


12


, frame

FIGS. 18 and 19

that allow for both horizontal and vertical rotation over hinge assemblies


30


.




Seat and outer leg sections


312


,


314


,


316


define between them a center leg opening


318


. Mattress


18


includes a drip flap


320


that extends downwardly around a portion of opening


318


. Drip flap


320


reduces exposure of deck


16


and frame


14

323


. Drip flap


320


in conjunction with catch basin


62


facilitates containment of fluids often encountered during procedures such as childbirth.




Mattress


18


further includes heel cut-outs


322


and foot straps


324


in outer leg sections


314


,


316


. Cut-outs


322


provide a support surface for a patient's foot when outer leg sections


314


,


316


are in a raised position, as shown for example in

FIGS. 5 and 7

. Mattress


18


illustratively includes foot end bevels


326


and head end bevels


328


as best shown in

In operation, when a patient is first placed on stretcher


10


, the stretcher


10


is located in the conventional stretcher configuration illustrated in FIG.


1


. The deck


16


can be articulated to adjust the position of the patient on the stretcher


10


. When it is desired to move the stretcher to the OB/GYN configuration, a caregiver will typically first move the outer leg sections


24


and


26


upwardly relative to the seat section


22


by depressing buttons


122


beneath the outer leg sections


24


,


26


. This releases pistons


121


and permits the outer leg sections to be pivoted upwardly as shown in

FIGS. 7-8

.




Next, the center leg support


17


,


117


is stowed. To stow the center leg support


17


,


117


, a caregiver pulls the release handles


64


,


164


, respectively, toward the foot end


56


of stretcher


10


. This releases pins


68


,


168


from apertures


70


formed in deck


16


. Therefore, the center leg support


17


,


117


can be pivoted downwardly about pivot blocks


82


as shown in FIG.


3


. Center leg support


117


is then pushed toward the head end


54


of stretcher


10


in the direction of arrow


96


and arrow


98


of

FIG. 3

to a storage position as shown in

FIGS. 4 and 5

.




Next, the caregiver located at foot end


56


of stretcher


10


grips both handles


104


as shown in FIG.


8


. Caregiver then actuates levers


102


by moving the levers


102


toward the foot end


56


of stretcher


10


. Actuation of levers


102


simultaneously releases the latches


106


and mechanical locks


128


coupled to control wires


108


and


109


, respectively. When pins


106


are released from both sides of the deck


16


, rollers


34


can roll in channels


36


,


38


toward the foot end


56


of the stretcher


10


to an examination position shown in FIG.


7


. Pins


106


will latch into apertures in channels


36


,


38


to maintain the deck in the examination position shown in FIG.


7


. Siderail


60


includes a padded bar


61


which is configured to provide a grip handle for the patient as best shown in FIG.


7


. Illustratively, the grip handle is formed by a generally S-shaped section formed in the bar


61


. However, the padded grip handle may be formed on a straight tube or bar of the siderail.




The caregiver can then adjust the leg sections


26


outwardly about pivot


24


while levers


102


are actuated. In other words, the caregiver can move the leg sections


24


,


26

. Pins


106


then latch in the second set of apertures formed in channels


36


,


38


to hold the deck


16


in the conventional stretcher configuration. Center leg support


17


,


117


is then retrieved from the storage position as shown in FIG.

. The caregiver pulls the center leg support


17


,


117


outwardly in the direction of arrow


72


of

FIG. 3

until the bar


84


latches over locking pins


88


of pivot blocks


82


. The center leg support


17


,


117


is then pivoted upwardly about pivot blocks


82


until pins


68


,


168


engage apertures


70


formed in deck


16


to lock the center leg support


17


,


117


, in position.




It is understood that the locations of pins


68


and holes


70


could be reversed. In addition, latch pins


106


could be formed on the frame and configured to enter apertures formed in the deck. Other types of latches may also be used, if desired.




Another aspect of the present invention is illustrated in FIG.


23


. The siderail


60


includes a mounting rail


350


and an outer rail


352


. The tubes or bars


61


of the siderail are pivotably coupled between the mounting rail


350


and the outer rail


352


. Swing arms


354


are mounted on each end of the siderails


60


. Each swing arm


354


includes a first end pivotably coupled to the frame


14


at location


356


and a second end pivotably coupled to the mounting rail


350


at location


358


. A separate siderail


60


is mounted on both sides of the frame


14


in a conventional manner.





FIG. 23

also illustrates a cam


360


coupled to the carriage plate


32


of the deck


16


. A cam


360


is coupled to carriage plates


32


on both sides of the deck


16


. When the deck


16


slides toward the foot end of the frame


14


in the direction of arrow


362


as discussed above, the carriage


32


and the cams


360


also move in the direction of arrow


362


. When the carriage


32


and cams


360


approach a foot end of the frame


14


, the cams


360


engage the swing arms


354


of the siderail


60


to pivot the siderails


60


outwardly relative to the frame


14


in the direction of arrow


364


to the dotted location illustrated in FIG.


23


. This movement of the siderails


60


provides clearance to permit the deck


16


to continue to move toward the foot end of the stretcher


10


.
