The present invention relates to the field of patient stretchers, more specifically, a patient stretcher that includes a patient lifting measure therein, and which enables the patient to lie undisturbed on the ground surface whilst being loaded onto said stretcher.
SUMMARY OF INVENTION
The ambulatory stretcher with patient lifting measures enables a patient to be loaded onto the ambulatory stretcher without moving. The ambulatory stretcher with patient lifting measures includes an outer frame that includes an opening, and which is adapted to be placed onto the ground immediately surrounding a patient. The outer frame includes a pair of patient-conveying members that extend and retract to close off or open up the opening in the outer frame. The patient-conveying members are able to extend underneath a patient whilst said patient is lying on the ground surface. Moreover, the patient-conveying members are able to load the patient onto the assembly without requiring any movement of the patient with respect to the ground surface. The patient-conveying members are each constructed of a “U”-shaped frame that includes a top conveyor member and a bottom conveyor member. The “U” shaped frame slides back and forth with respect to a channel located on a left side and a right side of the outer frame. The top conveyor member and the bottom conveyor member are each made of the same construction. Moreover, the top conveyor member and the bottom conveyor member each include a plurality of elongated triangular members that interlace with one another when fully extended into the outer frame, and which are adapted to support the weight of the patient thereon. The top conveyor member and the bottom conveyor member separate from one another when the “U” shaped frame slides outwardly.

The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments of the application and uses of the described embodiments. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to practice the disclosure and are not intended to limit the scope of the appended claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.
Detailed reference will now be made to a first potential embodiment of the disclosure, which is illustrated in FIGS. 1 through 5. The ambulatory stretcher with patient lifting measures 100 (hereinafter invention) comprises an outer frame 101 that includes an opening 102 thereon. The outer frame 101 is adapted to be placed onto a ground surface immediately surrounding a patient 200. The outer frame 101 includes a left channel 103 along a left side 104 of the outer frame 101, and a right channel 105 along a right side 106 of the outer frame 101. The left channel 103 and the right channel 105 extend across an outer frame width 107 of the outer frame 101. It shall be noted that the patient 200 may also be referred to as an object, and the invention 100 may be adapted for use in lifting said object 200 from said ground surface.
A left “U” shaped frame 108 is attached and slides inwardly as well as outwardly with respect to the left channel 103 of the outer frame 101. A right “U” shaped frame 109 is attached and slides inwardly as well as outwardly with respect to the right channel 105 of the outer frame 101. Both the left “U” shaped frame 108 and the right “U” shaped frame 109 include at least one handhold 110 provided along a “U” shaped frame length 111. More specifically, the left “U” shaped frame 108 includes the at least one handhold 110 adjacent a left frame edge 112 of the left “U” shaped frame 108. The right “U” shaped frame member 109 includes the at least one handhold 110 adjacent a right frame edge 113 of the right “U” shaped frame member 109.
The left “U” shaped frame 108 and the right “U” shaped frame 109 have a side opening 114 that corresponds with the respective side of the opening 102 of the outer frame 101. Both the left “U” shaped frame 108 and the right “U” shaped frame 109 are able to slide into and out of the outer frame 101 a traverse length 115. The left “U” shaped frame 108 extends inwardly and overlaps with the right “U” shaped frame 109 (see FIG. 6).
Both the left “U” shaped frame 108 and the right “U” shaped frame 109 include a top conveyor member 116 and a bottom conveyor member 117. The top conveyor member 116 and the bottom conveyor member 117 are constructed of the same materials, and each includes a plurality of elongated triangular members 118 that extend across the side opening 114 of the left “U” shaped frame 108 and the right “U” shaped frame 109. The plurality of elongated triangular members 118 of the top conveyor member 116 are oriented down, whereas the plurality of elongated triangular members 118 of the bottom conveyor member 117 are oriented up. The plurality of elongated triangular members 118 of the top conveyor member 116 are able to interlace with the plurality of elongated triangular members 118 of the bottom conveyor member 117. The interlacing of the plurality of elongated triangular members 118 is able to slide underneath the patient 200, in order to place the patient 200 onto the invention 100 without movement of the patient 200.
It shall be noted that the plurality of elongated triangular members 118 are somewhat flexible, and are able to rotate with respect to one another. The plurality of elongated triangular members 118 are linearly aligned, and successive ones of the plurality of triangular members are able to rotate with respect to one another. The side opening 114 of both the left “U” shaped frame 108 and the right “U” shaped frame 109 is further defined with a side opening width 133.
The top conveyor member 116 and the bottom conveyor member 117 interlace together an interlace length 134. The interlace length 134 is half of the side opening width 133. The interlace length 134 insures that the top conveyor member 116 and the bottom conveyor member 117 extend midway across the opening 102 in the outer frame 101. When both the left “U” shaped frame 108 and the right “U” shaped frame 109 are pushed inwardly, the top conveyor members 116 and the bottom conveyor members 117 extend from the left and the right in order to enclose the opening 102 in the outer frame 101. Moreover, the top conveyor members 116 and the bottom conveyor members 117 have an outer edge 166 that is affixed with respect to the outer frame 101, whilst an inner edge 167 is affixed to either the left “U” shaped frame 108 or the right “U” shaped frame 109.
It shall be further noted that the interlace length 134 is half of an opening width 135 of the opening 102 of the outer frame 101.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in FIGS. 1 through 6, include variations in size, materials, shape, form, function, and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention.
Is shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
