Definitions
- This invention relates to a stretcher (being an appliance for carrying a disabled person) and, more particularly but not exclusively, is concerned with a portable stretcher useful to emergency and rescue services.
- Stretchers of the "carrying sheet” type are readily transportable but are limited in their ability to provide rigid support over the full width and length of a supine human body.
- Those previously proposed portable stretchers which would provide ample support are too large and heavy to be readily transportable over long distances by a single human bearer.
- the present invention seeks to provide a fully supportive stretcher which is, at the same time more readily transportable than the prior proposals.
- a stretcher comprising means for providing a rigid surface large enough to provide support to a supine human body over substantially the entire width and length of the body, and an inflatable body cushioning means which is situated between the rigid surface and the supine human body in use of the stretcher.
- the combination of a rigid surface and an inflatable cushion combines lightness and strength, and thereby failitates transport of the stretcher, while empty, by a single human bearer.
- the means for providing a rigid surface is preferably constituted by (i) a body board made up from at least three rigid body support board portions which extend in a transverse direction across the full width of the board and in a longitudinal direction along a portion of the length of the board; and (ii) means for limiting movement of the board portions relative to one another to movement between a compact, transport disposition of the stretcher and a flat, useful disposition of the stretcher.
- a stretcher characterised in that it comprises a body board made up from at least three rigid body support board portions which extend in a transverse direction across the full width of the body board and in a longitudinal direction along a portion of the length of the board, and means for limiting movement of the board portions relative to one another to movement between a compact transport disposition of the stretcher and a flat useful disposition of the stretcher.
- the parts of the stretcher are preferably so shaped that, when the stretcher is in the transport disposition, the entire stretcher can be arranged as a back-pack, which is preferably such that no dimension exceeds one-third of the length of the stretcher when in use.
- the board portions are circumjacent the cushioning means, in the transport disposition, thereby affording some protection to the inflatable cushioning means in transport.
- the support board portions are connected by hinge formations, which can be of fabric, so retaining the body support board as a single component which can be folded into a compact configuration.
- a pack having a width which is similar to that of the stretcher, a thickness X approximately one-tenth of the length of the stretcher and a length Y approximately one-quarter of the length of the stretcher can be provided with a body support board having a central portion of length (along the length of the stretcher) X to which is joined by hinges two adjacent board portions of length Y, and then two further portions of length no more than X.
- these two further portions can be of length X/2 and connected to two end portions of the body support board having a length no greater than Y. If the two ends of such a board are folded in to the middle of the board then a pack of the same width as the support board and with X and Y as its other two major dimensions, will be formed.
- the body support board portions are made from a composite material of fibres set in a resin matrix in order to provide the maximum available stiffness consistent with a light weight.
- Stiffening means may be employed to limit relative movement of the board portions when the stretcher is in use.
- these stiffeners are of 25 mm square section aluminium alloy tube and are attached to the body support board so that they are not lost when the stretcher is dismantled. None of the stiffeners is longer than one-third of the length of the stretcher and, where it is convenient to connect together the stiffeners for use of the stretcher, this can be effected by the use of retractable inserts housed within the ends of the stiffener tubes.
- buoyancy tubes along the flank edges of the body support board, so that the stretcher is capable of supporting an injured person on the surface of a body of water.
- the lower surfaces of the buoyancy tubes are resistant to abrasion and are faired at one end at least of the stretcher so that the stretcher is more readily suitable to be handled as a sledge in use i.e. is adapted for sledging.
- the upper surface of the body support board is provided with an inflatable mattress and has a sufficient number of straps or bindings to enable the necessary restraint to be applied to the injured person on the stretcher. It is useful to divide the mattress into a trunk cushion and a head cushion, and to provide means for establishing a degree of inflation of the head cushion different from that of the trunk cushion.
- a survival cover or sheet will be provided to extend over the body support board for covering the injured person and conveniently this is in two halves connected by a zip fastener running centrally along the length of the sheet or cover.
- the trunk and legs of the body of an injured person 10 is borne on an inflatable mattress 11 carried between two large buoyancy tubes 12 and 13.
- the head of the patient 10 rests upon a V-shaped headrest cushion 14, and his body is covered by a laminated survival cover 15 which incorporates leaves of the so-called "Space Blanket" material for resisting loss of heat from the patient 10.
- a transparent visor for covering the head of the patient 10, when necessary.
- the survival cover 15 has a centrally placed zip fastener 16 running the entire length of the cover, and tags 17 which engage studs on the tubes 12 and 13 with a snap action.
- Fig. 1 shows that the main buoyancy tubes 12 and 13 are connected by a front thwart support tube 18 and rear tube 19.
- This rear tube carries a main inflatable valve 20 through which supplies of compressed air or, if desired, compressed carbon dioxide gas, may be introduced into the inflatable cavities of the stretcher.
- a bottle 21 of sufficient compressed gas to inflate the stretcher may be secured to the rear tube.
- the gas passes directly from the tube 19 into the main buoyancy tubes 12 and 13 and the front thwart support tube 18, but indirectly, through a mattress inflation cock 22, into the mattress 11 and the headrest 14.
- a mattress inflation cock 22 into the mattress 11 and the headrest 14.
- the amount of air in the headrest is controllable by a deflation valve 23, and the amount of air in the mattress 11 by a mattress deflation valve 24.
- the front thwart support tube 16 carries a pressure relief valve 25 and a deflation plug 26.
- a number of lifting rings and handles 27 are provided around the periphery of the stretcher.
- Fig. 1 shows one possible arrangement of straps and harness bonded to the inflatable mattress 11, the main buoyancy tubes 12 and 13 and the body support board beneath the mattress 11 and described further hereinbelow, to provide the necessary restraint for an injured person lying on the stretcher.
- the various straps and harness incorporated quick release buckles 28.
- the straps may therefore comprise a head strap 29, a chest strap 30, groin straps 31 and 32 a knee strap 33 and an ankle strap 34, adjustable, diagonal body-securing harness straps 35 and 36, a plurality of leg-securing loops 37 and several traction loops 38.
- the ends of the buoyancy tubes 12 and 13 are faired into a smoothly rounded shape to facilitate "sledging” i.e. dragging, the stretcher over the ground.
- the ground-contacting surfaces of the stretcher are protected against abrasion if such use is contemplated.
- the illustrated embodiment is adapted to be safely towed over a water surface, as the stretcher floats thereon.
- Fig. 3 shows that the body support board 40 is made up of a relatively short central board portion 41 flanked by two large portions 42 and 43, flanked in turn by two rather short portions 44 and 45 and then two equal sized end portions 46 and 47, the adjacent portions of the board being connected to one another by fabric hinges 48 and together providing a board having a length of nearly 2 m and a width of approximately 40 cms.
- the portion 42 has a pair of slots 49 and 50
- the portion 43 has a pair of slots 51 and 52
- the end portion 46 (which underlies the headrest 14) has a pair of slots 53 and 54.
- each of the slots is slidably movable an aluminium slide member 55 to 60 respectively.
- the hinges allow the string to pivot through a right angle between a relaxed disposition flat on the board 40 as shown in Fig. 3 and a standing disposition perpendicular to the board 40 as shown in Fig. 6, referred to hereinbelow.
- the string 64 comprises an end element 65 of marine grade plywood connected to the hinge 61 and by a strong brass hinge 66 to a first centre element 67 which overlies the centre board portion 41.
- This element 67 is connected by a similar brass hinge 68 to a compensating element 78 which overlies the board element 43.
- a short element 69 is connected by a brass hinge 70 to the compensating element 78 and by another brass hinge 71 to an end element 72 itself connected to the fabric hinge 63.

Abstract
Description
- This invention relates to a stretcher (being an appliance for carrying a disabled person) and, more particularly but not exclusively, is concerned with a portable stretcher useful to emergency and rescue services.
- There have been a number of prior proposals for stretchers to be used by emergency and rescue services. Stretchers of the "carrying sheet" type are readily transportable but are limited in their ability to provide rigid support over the full width and length of a supine human body. Those previously proposed portable stretchers which would provide ample support are too large and heavy to be readily transportable over long distances by a single human bearer.
- The present invention seeks to provide a fully supportive stretcher which is, at the same time more readily transportable than the prior proposals.
- According to a first aspect of the present invention there is provided a stretcher comprising means for providing a rigid surface large enough to provide support to a supine human body over substantially the entire width and length of the body, and an inflatable body cushioning means which is situated between the rigid surface and the supine human body in use of the stretcher.
- The combination of a rigid surface and an inflatable cushion combines lightness and strength, and thereby failitates transport of the stretcher, while empty, by a single human bearer.
- The means for providing a rigid surface is preferably constituted by (i) a body board made up from at least three rigid body support board portions which extend in a transverse direction across the full width of the board and in a longitudinal direction along a portion of the length of the board; and (ii) means for limiting movement of the board portions relative to one another to movement between a compact, transport disposition of the stretcher and a flat, useful disposition of the stretcher.
- The compactness of the transport disposition makes it possible to provide a stretcher light enough and small enough to be carried easily by one person, and this may be so even if no inflatable cushioning means is provided. Thus, according to a second aspect of the invention there is provided a stretcher characterised in that it comprises a body board made up from at least three rigid body support board portions which extend in a transverse direction across the full width of the body board and in a longitudinal direction along a portion of the length of the board, and means for limiting movement of the board portions relative to one another to movement between a compact transport disposition of the stretcher and a flat useful disposition of the stretcher.
- The parts of the stretcher are preferably so shaped that, when the stretcher is in the transport disposition, the entire stretcher can be arranged as a back-pack, which is preferably such that no dimension exceeds one-third of the length of the stretcher when in use. Preferably the board portions are circumjacent the cushioning means, in the transport disposition, thereby affording some protection to the inflatable cushioning means in transport.
- Preferably the support board portions are connected by hinge formations, which can be of fabric, so retaining the body support board as a single component which can be folded into a compact configuration. Thus, a pack having a width which is similar to that of the stretcher, a thickness X approximately one-tenth of the length of the stretcher and a length Y approximately one-quarter of the length of the stretcher can be provided with a body support board having a central portion of length (along the length of the stretcher) X to which is joined by hinges two adjacent board portions of length Y, and then two further portions of length no more than X. In particular, these two further portions can be of length X/2 and connected to two end portions of the body support board having a length no greater than Y. If the two ends of such a board are folded in to the middle of the board then a pack of the same width as the support board and with X and Y as its other two major dimensions, will be formed.
- Conveniently the body support board portions are made from a composite material of fibres set in a resin matrix in order to provide the maximum available stiffness consistent with a light weight.
- Stiffening means may be employed to limit relative movement of the board portions when the stretcher is in use. In one embodiment, not at present preferred, but described in British Patent Application No. 8117596, the priority of which is claimed herein, these stiffeners are of 25 mm square section aluminium alloy tube and are attached to the body support board so that they are not lost when the stretcher is dismantled. None of the stiffeners is longer than one-third of the length of the stretcher and, where it is convenient to connect together the stiffeners for use of the stretcher, this can be effected by the use of retractable inserts housed within the ends of the stiffener tubes.
- It will usually be advantageous to provide buoyancy tubes along the flank edges of the body support board, so that the stretcher is capable of supporting an injured person on the surface of a body of water. Conveniently the lower surfaces of the buoyancy tubes are resistant to abrasion and are faired at one end at least of the stretcher so that the stretcher is more readily suitable to be handled as a sledge in use i.e. is adapted for sledging. Again, it will often be convenient to nip the buoyancy tubes in at the waist area to restrict the overall width of the stretcher (for example, to not more than one metre so that the stretcher can readily be passed through doorways) and to provide a convenient location point for the connection between the buoyancy tubes and the body support board.
- Advantageously the upper surface of the body support board is provided with an inflatable mattress and has a sufficient number of straps or bindings to enable the necessary restraint to be applied to the injured person on the stretcher. It is useful to divide the mattress into a trunk cushion and a head cushion, and to provide means for establishing a degree of inflation of the head cushion different from that of the trunk cushion. Usually a survival cover or sheet will be provided to extend over the body support board for covering the injured person and conveniently this is in two halves connected by a zip fastener running centrally along the length of the sheet or cover.
- For a better understanding of the invention, and to show more clearly how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which:
- Fig. 1 is a plan view of one embodiment of a stretcher according to the invention, when inflated and in its flat disposition, but with a survival cover removed for reasons of clarity;
- Fig. 2 is a side elevation of the stretcher of Fig. 1 but with the survival cover included;
- Fig. 3 is a plan view of the body board of the stretcher with one stiffener removed in order to show slots in the body board;
- Fig. 4 is a side elevation of the stretcher when it is in its compact, transport disposition;
- Fig. 5 is a diagrammatic cross-section of the stretcher, on the line V-V shown in Fig. 1;
- Fig. 6-is an enlarged detail of Fig. 5 showing the attachment of one stiffener element to an associated portion of the body board; and
- Fig. 7 is an enlarged detail of Fig. 4 showing the construction of one of the fabric hinges connecting two adjacent portions of the body board of the stretcher.
- Referring to Figs. 1 and 2, the trunk and legs of the body of an
injured person 10 is borne on aninflatable mattress 11 carried between twolarge buoyancy tubes patient 10 rests upon a V-shaped headrest cushion 14, and his body is covered by a laminatedsurvival cover 15 which incorporates leaves of the so-called "Space Blanket" material for resisting loss of heat from thepatient 10. Also provided, but not shown, is a transparent visor for covering the head of thepatient 10, when necessary. Thesurvival cover 15 has a centrally placedzip fastener 16 running the entire length of the cover, andtags 17 which engage studs on thetubes - Fig. 1 shows that the
main buoyancy tubes thwart support tube 18 andrear tube 19. This rear tube carries a maininflatable valve 20 through which supplies of compressed air or, if desired, compressed carbon dioxide gas, may be introduced into the inflatable cavities of the stretcher. Abottle 21 of sufficient compressed gas to inflate the stretcher may be secured to the rear tube. - The gas passes directly from the
tube 19 into themain buoyancy tubes thwart support tube 18, but indirectly, through amattress inflation cock 22, into themattress 11 and theheadrest 14. Between themattress 11 andheadrest 14 there is a non-return valve shown in the drawing purely schematically at 39. The amount of air in the headrest is controllable by adeflation valve 23, and the amount of air in themattress 11 by amattress deflation valve 24. With this arrangement, it is possible to deflate themattress 11 entirely, while all the other inflatable components of the stretcher remain fully inflated, and this may be useful for spinal patients or where some other form of mattress is to be used. - The front
thwart support tube 16 carries apressure relief valve 25 and adeflation plug 26. Around the periphery of the stretcher there are provided a number of lifting rings and handles 27. - Fig. 1 shows one possible arrangement of straps and harness bonded to the
inflatable mattress 11, themain buoyancy tubes mattress 11 and described further hereinbelow, to provide the necessary restraint for an injured person lying on the stretcher. Conveniently, the various straps and harness incorporatedquick release buckles 28. The straps may therefore comprise ahead strap 29, a chest strap 30,groin straps 31 and 32 aknee strap 33 and anankle strap 34, adjustable, diagonal body-securingharness straps loops 37 andseveral traction loops 38. - As best seen in Fig. 2, the ends of the
buoyancy tubes - Fig. 3 shows that the
body support board 40 is made up of a relatively shortcentral board portion 41 flanked by twolarge portions short portions end portions fabric hinges 48 and together providing a board having a length of nearly 2 m and a width of approximately 40 cms. - The
portion 42 has a pair ofslots portion 43 has a pair ofslots slots aluminium slide member 55 to 60 respectively. Connected to theslide member 55 by afabric hinge 61, theslide member 57 by afabric hinge 62 and theslide member 59 by afabric hinge 63 is a stiffener string generally referenced 64. The hinges allow the string to pivot through a right angle between a relaxed disposition flat on theboard 40 as shown in Fig. 3 and a standing disposition perpendicular to theboard 40 as shown in Fig. 6, referred to hereinbelow. - The
string 64 comprises anend element 65 of marine grade plywood connected to thehinge 61 and by astrong brass hinge 66 to afirst centre element 67 which overlies thecentre board portion 41. Thiselement 67 is connected by asimilar brass hinge 68 to a compensatingelement 78 which overlies theboard element 43. Ashort element 69 is connected by abrass hinge 70 to the compensatingelement 78 and by anotherbrass hinge 71 to anend element 72 itself connected to thefabric hinge 63. - A string which is mounted to the
slide members string 64 and a mirror image of it. It is omitted from Fig. 3 the better to show theslide members - The way in which the strings function will become clearer from the description of Fig. 4 which follows. The length of the compensating
element 78 is variable by a small extent, as is shown diagrammatically in Fig. 3 by amale member 73 of afirst portion 74 of the compensating element which is slidable in achannel 75 in asecond portion 76 of theelement 78. - Fig. 4 shows the
body board 40 andstiffener string 64 in the compact, transport disposition of the stretcher, and it is believed that inspection of the reference numbers will reveal the manner in which the board and string is folded. It will be appreciated that the brass hinges 66, 68, 70 and 71 each fold at the position of one of the fabric hinges 48 connecting adjacent body board portions, and that the compensatingelement 78 serves to secure sufficient variation in the distance separating the brass hinges 68 and 70 to allow thebody board 40 to move between its folded, compact disposition and its flat disposition. - Turning now to Fig. 5, it can be seen that the
main buoyancy tubes section reeds end flanges 82 of the reeds are secured to the outer surface of the buoyancy tubes, and then further secured by fabric holding covers 83 as shown in the drawing. An alternative, but less preferred, arrangement would be to secure end flanges of thereeds buoyancy tubes -
Strips 84 of material secure thebuoyancy tubes body support board 40 of the stretcher. Theboard 40 is supported as described above bystiffener strings inflatable mattress 11 of the stretcher on its upper surface. The construction of themattress 11, as shown in Fig. 5, is conventional and need not be described further herein. Above themattress 11 is shown thesurvival cover 15. Fig. 5 shows sheets of abrasion-resistant material 86 may be bonded to the lower surfaces of thebuoyancy tubes tubes - The detail view of Fig. 6 shows the
stiffener element 65 secured to theslide member 55 by thefabric hinge 61 which comprises awide strip 87 and anarrow strip 88 of fabric which together flank the lower longitudinal edge 89 of theelement 65 and extend through aslot 90 defined by a slottedelement 91 of theslide member 55. The lower edges of thestrips element 91 and an upward-facing surface of a facingelement 92 of theslide member 55. - The slots and slide members in the body board are protected from contact with dirt or water from below the body board by waterproof
protective covers 93 of polyvinylchloride bonded to the lower surface of thebody board 40 and within which theslide members 55 to 60 can move along their respective slots. - It will be appreciated from study of Fig. 6 that if the
mattress 11 is deflated, the stiffener strings 64 and 85 can take up (arrow f) the relaxed disposition, flat above theboard 40 and overlying an edge of the deflatedmattress 11, and that as themattress 11 is inflated the strings will be pushed into the standing disposition shown in Figs. 5 and 6. - In fact, inflation of the stretcher from the compact disposition of Fig. 4 to the flat disposition of Figs. 1 and 5 can be automatic, the inflation of the
mattress 11 first urging thebody board 40 to open out flat and then urging the stiffener strings to assume their standing disposition in which, it will be appreciated, they are each sandwiched between one of theflank tubes mattress 11. This sandwiching helps to keep the stiffener strings 64 and 85 properly upright, and ensures that the fabric hinges 61 are not required to withstand an unbalanced pressure from the inflatedmattress 11 during use of the stretcher, thereby protecting the fabric hinges 61 to 63 against undue tension and wear. - Fig. 7 shows one of the fabric hinges 48 when fully open. Each hinge has two
fabric hinge members 90 each bonded to two adjacent portions of thebody board 40 and connected to one another by acentre stitch 91. Short lengths offabric holding tape 92 cover the area of the hinge and, in particular, the exposed surface of thecentre stitch 91. - It will be appreciated that the
flank tubes body board 40 far enough to overlie thebody board portions - It will further be appreciated that the
flank tubes body board 40 so that, in the transport disposition of the stretcher, the body board surrounds and protects the other components of the stretcher.
