Abstract
A patient transport device is disclosed which includes a seat member, a back member, a leg supporting member, and a head supporting member. The device may be unfolded to a position wherein the patient may be transferred thereon in a supine position. The back member may be selectively adjustably positioned with respect to the seat member so that the patient may be transferred thereon in a sitting position with either the patient's legs hanging downwardly from the seat member or extending outwardly therefrom in a horizontal position. Various carrying straps are provided on the device to enable the patient to be easily transported in either the supine position or in a seated position. Restraining straps are also provided.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates to a patient transport device and more particularly to a patient transport device which is capable of transporting a patient in either a sifting position or a supine position. In the sitting position, the patient's legs may either hang downwardly or be extended horizontally outwardly from the seat member of the device.




2. Description of the Related Art




Many types of patient transport devices have been provided to enable paramedics or the like to move or transport a patient from a patient's home or accident scene to an ambulance and then transport the patient from the ambulance into the hospital. If the patient is to be transported in a supine position, a stretcher or spine board is normally utilized. One disadvantage in using a stretcher is that the patient must normally be lifted onto the stretcher which can be a painful experience for the patient due to the fact that the patient must be grasped beneath the shoulders, legs, etc., to manually lift the patient onto the stretcher. Although it is somewhat easier to place the patient on a spine board than on a stretcher, the spine board is somewhat difficult to grasp and carry. Both stretchers and spine boards suffer from the further disadvantage in that they are difficult to maneuver in close quarters, around corners, etc. In some cases, the patient cannot be transported in a supine position due to patient infirmities or injuries or the patient's location is such that a stretcher or spine board cannot be used. In those cases, the patient is sometimes strapped into a conventional chair which requires that the patient be manually lifted into the chair. Further, when a chair is used to transport the patient, the chair is difficult to grasp and carry. Additionally, in some cases where the patient is to be transported in a chair, there is no convenient method whereby the patient's legs can be extended outwardly form the chair in a horizontal position.




SUMMARY OF THE INVENTION




A patient transport device is disclosed which enables a patient to be transported in a supine position or a sifting position with the patient's legs either hanging downwardly therefrom or extending outwardly therefrom in a horizontal position. The device is extremely portable in that it can be folded together and easily placed into a carrying bag.




The device generally consists of a seat member, a back member, a leg supporting member, and a head supporting member. The back member is hingedly secured to the rear end of the seat member and may be folded forwardly onto the seat member for storage. The back member may be folded to a horizontal position to enable the patient to be transported in a supine position or folded to an upright position, or any position therebetween. Length adjustable support straps extend between the sides of the seat member and the sides of the back member to selectively maintain the back member in selected positions with respect to the seat member.




The head supporting member is hingedly secured to the front surface of the back member below the upper end thereof and is movable from a stowed position adjacent the front surface of the back member to an operative head supporting position wherein it extends from the upper end of the seat member to support the head of the patient whether the patient is in a sitting position or in a supine position.




A flexible leg supporting member extends from the forward end of the seat member and is normally stowed beneath the seat member and behind the lower portion of the back member. The leg supporting member may be moved from its stored position to a position wherein it extends outwardly from the forward end of the seat member to support the legs of the patient who is either in a sitting position or a supine position.




Carrying straps are attached to the back member, seat member, and leg supporting member and extend laterally outwardly therefrom. The carrying straps may be stowed in a folded condition when not in use. A plurality of restraining straps are secured to the device to restrain the patient on the device. The back member, seat member, and head supporting member include plastic sheet members enclosed with a compartment to enable the sheet members to be removed from the compartments to enable the device to be cleaned and/or sanitized.




It is therefore a principal object of the invention to provide an improved patient transport device.




A further object of the invention is to provide an improved patient transport device which enables a patient to be transported in either a supine or sitting position.




A further object of the invention is to provide an improved patient transport device which enables the patient to be transported in a sitting position.




Yet another object of the invention is to provide an improved patient transport device which enables the patent to be transported in a sitting position with the patient's legs either hanging downwardly from the seat thereof or extending outwardly therefrom.




A further object of the invention is to provide an improved patient transport device which enables a patient to be transported in either a supine or sitting position which is convenient to use.




A further object of the invention is to provide an improved patient transport device which enables a patient to be transported in either a supine or sitting position which is conveniently stored in a compact fashion.




Yet another object of the invention is to provide an improved patient transport device which enables a patient to be transported in a sitting position with the angle of the back member being selectively adjustable with respect to the seat member of the device.




These and other objects will be apparent to those skilled in the art.

FIGS. 9 and 10

illustrate the manner in which the angular relationship of back member


14


may be changed with respect to seat member


12


so that the patient being transported thereon may be positioned in the most comfortable position.




In

FIG. 8

, a carrying bag or storage bag is illustrated and is generally referred to by the reference numeral


156


. The carrying bag


156


is adapted to receive the device


10


therein when the device is in its completely folded storage position. A length adjustable strap having a male connector


160


at one end thereof and a female


162


at the other end thereof is selectively connected to connectors


164


and


166


which are secured to the bag


156


to provide a convenient means of carrying the bag


156


. The carrying strap


158


also performs an additional function in that it may be removed from the bag


156


and looped around the carrying straps


118


, as seen in

FIG. 1

, to assist in carrying the patient.




In operation, the device


10


is normally stowed folded in a flat position and placed within the carrying bag, as seen in FIG.


8


.

FIG. 7

illustrates the device in its completely folded position. In the folded position of

FIG. 7

, the carrying handles


116


and


118


are folded beneath leg supporting member


18


and maintained in that position by the hook-and-loop fasteners, as previously described. Similarly the carrying straps


126


and


128


are folded to the stowed position, as illustrated in FIG.


4


. The carrying handles


140


and


142


are also folded inwardly so as to be positioned adjacent the back surface of back member


14


and maintained in that position by the hook-and-loop fasteners, as previously described. The leg supporting member


18


is also folded so as to be positioned beneath the bottom of seat member


12


and behind the seat member


14


, as illustrated in FIG.


6


. The hook-and-loop fasteners previously described maintain the leg supporting member


18


in the position of FIG.


6


. When the device


10


is in the folded position, the head supporting member


16


will be in its folded position with that folded position being illustrated by broken lines in FIG.


2


. When in the folded position, the device


10


will have the front surface of back member


14


positioned adjacent the top surface of seat member


12


. One or more of the restraining straps may be extended around the folded seat and back members to maintain the device in the folded position.




When it is necessary to transport a patient, the device


10


is removed from the carrying bag


156


. If the patient is to be transferred in a sitting position, the adjustable straps


152


and


154


are length adjusted so that the back member


14


will extend upwardly from seat member


12


. If it is desired that the patient's legs hang downwardly from the seat member


12


, the leg supporting member will be left in the position illustrated in FIG.


9


. If it is desired to support the legs of the patient in a horizontal patient when the patient is seated on the device, the leg supporting member


18


is moved from the position of

FIG. 9

to the position of FIG.


10


. The carrying straps


114


,


124


and


138


may be moved from their stowed position to their operative position to provide carrying handles at opposite sides of the device to enable the patient to be easily carried.




If it is desired to transport the patient in a supine position, the length adjustable straps


152


and


154


are loosened so that the back member


14


may be hingedly moved with respect to seat member


12


so that back member


14


is generally parallel to seat member


12


. Head supporting member


16


is then moved from the dotted line position of

FIG. 2

to the solid line position of

FIG. 2

so that head supporting member


16


extends beyond the upper end


42


of back member


14


, as illustrated in FIG.


2


. The plastic plate inside the head supporting member


16


provides the necessary rigidity for supporting the patient's head. Although the plastic plates in the head supporting member


16


, seat member


12


, and back member


14


are generally rigid, they do bend somewhat to cradle the patient's body therein. The plastic plates or sheet members within sheet member


12


, back member


14


, and head supporting member


16


are removable so that the device may be cleaned and sanitized.




Thus it can be seen that a novel patient transport device has been provided which enables the patient to be transported in either a supine position or in a sitting position. Further, the versatility of the device enables the patient to be transported without physically grasping the patient during the transporting procedure. It has been found that the low profile nature of the device, when in the supine transporting position, enables the patient to be easily positioned on the device. Assuming that the patient is lying on a floor or the like, the device is positioned alongside the patient and slipped beneath the patient with a minimum of patient contact.




Thus it can be seen that the invention accomplishes at least all of its stated objectives.
