Abstract

The stretcher-bed includes a stretcher (1) having two longitudinal bars (61,62) separated by two transverse bars (8) and covered with a canvas to define a sleeping surface. The frame has handles (7) at the ends of the longitudinal bars and feet (3) so that it can be positioned on the ground. The frame also has four legs (6) that co-operate with actuators formed from actuating levers (111,112) and pistons (101,102), that enable displacement of the legs from a position parallel and against the longitudinal bars to upright positions, enabling the stretcher to be transformed into a bed.

Description

(9) intended to be implanted in the medullary canal of the tibia.

  The present invention relates to a folding stretcher and

  stackable more specifically intended to be used for recovering and trans-

  wear sick or injured people in mobile or stationary vein rooms, especially in military hospitals or first aid settings during an intervention, in war time or even

  in areas affected by natural disasters.

  In times of war, conflict or humanitarian operations after natural disasters or major accidents, rescuers must most often look for the sick or wounded with bran o cards which correspond to essential items for their transport.

  Such stretchers, which are standardized, are classi-

  only an essentially rectangular framework, preferably metal-

  lique covered with a canvas defining a relatively narrow sleeping surface and equipped with heels allowing its positioning

  on the ground at a height of a few centimeters.

  This framework is generally constituted by two parallel beams, in particular in aluminum profile connected by transverse bars and extending on either side by telescopic handles respectively intended to be gripped by two carriers, one of which is place at the front of the stretcher while the other is place at

the back of it.

  When transported on a stretcher, the wounded are maintained on the sleeping surface by means of belt trots, sou

  wind completely flat, possibly with a cushion under the party.

  These belts can be extended to allow their use in the particular case where the wound has been placed on a mattress

vacuum immobilizer.

  During wartime interventions, and even in

  o maneuver, injuries of any kind can occur.

  First aid is then frequently given

  even on the stretcher, especially during the transport of the injured in am-

  military bulance, to a military or maneuver camp set back from the battlefield or further veins or medical interventions: 5 can be carried out, while the wounded is still lying a few

  centimeters from the floor on the stretcher's sleeping surface.

  Indeed, for strategic reasons of size and weight, the first aid tenses at the combat front do not have support trolleys suitable for standardized stretchers. As a result, the nursing staff cannot have vein or operating tables with an appropriate height of at least 45 cm, and must perch or kneel to perform the first necessary medical veins during the waiting time. until the wounded is transported to

  a hospital, which is particularly inconvenient.

  In addition, the width of the sleeping surface of the standard stretchers, which cannot be increased, is insufficient to guarantee the comfort of the wounded and it would be desirable to offer them more space 0 in particular at the level of the shoulders at the seat, which could also allow nursing staff to have arm and hand rests to facilitate intravenous injections or place upper limbs

laughing injuries or fractures.

  However, in wartime, an injured person remains on average 15 layers at ground level on a stretcher for a period of 9 to 96 hours until his transport to a better equipped military hospital, very far from

front or battlefield.

  It should also be noted that in the case of natural disasters or major accidents with a very large number of wounded, transport to a better equipped center cannot be organized as intended, and the wounded often have to wait very long for their repatriation. . In view of the aforementioned situation, the rescuers would like to be able to have stretchers that are both light, not very bulky and manageable, capable of replacing the standard standardized stretchers, in particular when transporting the injured in ambulances or specialized aircraft. fitted with suitable fastening systems, and at the same time able to offer improved comfort to the wounded than to

nursing staff.

  The purpose of the present invention is to meet this expectation by proposing a stretcher of the above-mentioned type capable of being trans

form into a bed.

  According to the invention, this bed stretcher is characterized in that the frame is equipped with four extension legs cooperating with: 5 actuation means making it possible to move them between on the one hand a low position in which they are respectively folded down two by two against one of the side members, and on the other hand a high position in which they form a right angle with the lying surface of faOcon a allows to be to transform the stretcher into a bed, without adding or removing the pie

  these detached and without the aid of tools.

  In the high position, the extension feet allow you to

  rantant a height of bed and vein of the order of 52 cm.

  It is particularly advantageous in accordance with the invention that during their movement between the high position and the low position, the four extension feet move in the same direction. According to a preferential characteristic of the invention, the wind actuation means constituted by two adjustment levers respectively located at the level of the telescopic handles in particular below these, on one side of the framework, and connected to two blo cylinders

  queurs each cooperating with two extension feet.

  In the low position, the two extension feet actuated by one of the wind blockers folded in the same direction against one of the

side members or associated side member.

  I1 goes without saying that the actuating means must preferably cooperate with safety members capable of locking the blocking veins to exclude any accidental displacement of the feet of the extension o between the high position and the low position, whatever this is either to prevent any involuntary deployment of the extension feet in the high position or any untimely folding of this so as to damage

  a fall of the wounded lying on the stretcher.

  In view of this configuration, to transform the stretcher into a bed, the wearer located on the side of the adjustment levers must slightly pull them upwards so as to actuate the locking cylinders so that each releases the two associated extension legs up to that they move at right angles in the high position. This is clearly

  a particularly easy operation.

  Before carrying it out, the wearer must activate the safety devices so that they release the blocking jacks. As soon as the extension legs are fully extended

  on each side of the frame, the stretcher bed can be placed on the floor.

  The folding of the respective extension feet, against the associated side members, in the low position is carried out in a similar manner in the opposite direction, while the stretcher bed is raised from the ground. To carry out this maneuver, the wearer located on the side of the adjustment levers must actuate the safety members and then pull these levers so as to be released.

  the blocking cylinders and the extension feet, accompanying the movement

  ment of folding of the latter towards the associated longitudinal members, in advance

  cant or backward, while lowering the stretcher-bed, until its heels rest on the ground, in the basset position I1 it should be noted that this configuration makes it possible to avoid that one or the other of the feet is blocked by an accidental shape of the ground, as would be the case if the extension legs folded down

  inward against each other.

  o According to another characteristic of the invention, the feet of

  wind extension fitted with braked wheels at their ends.

  The presence of these wheels allows the displacement of the card-bed bran on flat ground, avoiding having to carry all the weight of the wounded layer on it, in particular during the journey from the camp of veins jus

  s the ambulance or the transport plane.

  It should be noted that in order not to oblige to automatically mount brake wheels on each stretcher bed, it is possible to associate special rolling carts on which they can be placed and transported. The stretcher bed according to the invention can also, if necessary, be fitted with an adjustable serum holder in length and capable of being maintained throughout the waiting period of the first hours.

  or even during the transport of the wounded by ambulance or by plane.

  I1 is also sonhaitable, for obvious economic reasons, that not only the weight but also the size of the stretcher bed then feels to be reduced to the maximum lo rs de

  its storage and transport << a vice>.

  According to a preferential characteristic of the invention capable of satisfying this imperative, the transverse bars of the wind frame constituted by bars articulated at their middle part so as to allow the stretcher-bed to be moved between a position on the one hand folded or lying position and on the other hand a folded position or position of storage and transport has vice>, in which both

  wind rails folded against each other.

  s The stretcher-bed according to the invention can thus be folded lengthwise, which makes it possible to reduce its overall dimensions as much as possible. s As has already been indicated, another drawback of conventional standard stretchers is linked to the small width of the sleeping surface which is insufficient to provide satisfactory comfort to the

injured only to caregivers.

  It would therefore be desirable to be able to widen at least one

part of this surface.

  According to another particularly advantageous characteristic of the invention making it possible to satisfy this imperative, the stretcher-bed is equipped with lateral widening flaps mounted on either side

o the sleeping surface.

  It should be noted that these widening flaps can be provided on one or both sides of the sleeping surface, on its entire length or only on a part thereof, and be

removable or fixed.

  In the latter case, the widening flaps can, when not in use, be folded laterally under the overhang

  sleeping face and locked in this position.

  To improve the comfort of the wounded and the self-sufficient staff it is essential that the sleeping surface can be widened not only when the stretcher bed is in the high position, but also when it is in the low position, the extension legs being folded down against

the associated side members.

  In fact, the stretcher bed in accordance with the invention is also capable of being used like a regular stretcher, during the transport of the injured in ambulances or special aircraft equipped with standardized fastening systems designed to fix the stretcher to flat at the level of the four heels located under the frame or by means of straps

  fixing at the level of the telescopic handles.

  The widening flaps only lose a little space for movement for the nursing staff, who depending on the interventions to be made, may decide to remove these flaps in order to

  see approaching closer to the wounded to be treated.

  According to another characteristic of the invention, the sleeping surface is constituted by a central seat on which the wind hinges a bust lifter and a leg lifter cooperating respectively with

  positioning members for adjusting their inclination.

  The bust lift can advantageously be fitted with a

integrated airbag.

  In accordance with this configuration, the sleeping surface can also be widened with the aid of enlarging flaps, preferably removable and in several parts, in particular a part ranging from

  the central seat to the bust lifter and a part associated with the leg lifter.

  s These widening flaps can still be placed there

  one side of the stretcher bed or two sides.

  It is also possible to equip the part located at the level of the central seat with a folding barrier system preferably

constituted by an elastic band.

  o According to another characteristic of the invention, the positioners are made up of rack mounted between the bust lifter or the leg lifter on the one hand and the side members or the transverse bars of the framework of on the other hand and allowing multiple positions

adjustment.

  i5 The characteristics of the stretcher bed which is the object of the invention will be described in more detail with reference to the appended drawings in which: FIG. 1 is a perspective view of the stretcher bed in the high sleeping position, o - Figures 2 and 3 wind perspective views correspond to Figure 1 showing the bust and leg lifter in the raised position, - Figure 4 is a perspective view of the stretcher bed in the lower sleeping position, - the FIG. 5 is a perspective view of the stretcher-bed in the storage and transport position "a vice '>, - Figure 6 is a perspective view of the framework of the stretcher-bed in the high sleeping position, - Figure 7 is a perspective view of the frame of the stretcher in the lower sleeping position, - Figure 8 is a perspective view of the frame of the stretcher in the storage and transport position aa vice> ' , - Figure 9 is a top view of the frame of the bed stretcher in position low bed, - Figure 10 is a top view of the frame of the stretcher in po

  3s storage and transport location has a defect>.

  According to Figures 1 to 4, the stretcher bed has a frame 1 covered with a canvas preferably a washable plastic canvas for

  before being disinfected defining a sleeping surface 2.

  The frame 1 is also equipped with four trapezoid heels

  daux 3 allowing its positioning on the ground in a low lying position represented in FIG. 4 in which the surface of

  sleeping 2 is located at a height of a few centimeters from the ground.

  The frame 1 is moreover equipped with four long idler feet 4 which can be moved in a manner which will be described in more detail in the remainder of this description between a low position represented in FIG. 4 in which they are folded against the sleeping surface 2 so as to allow it to rest on the ground by the heels 3, and a high position represented in FIGS. 1 to 3 in which they form a right angle with the sleeping surface 2 so to allow

transform the stretcher into a bed.

  According to Figures 2 and 3, the sleeping surface 2 is made up of three trots, namely a central seat 2 on which wind ar

  a bust lifter 22 and a leg lifter 23.

  The inclination of the bust lifter 22 and the leg lifter 23 can be adjusted according to several adjustment positions thanks to racks not shown in the figures, which wind mounted between these parts on the one hand

  elements 2, 23 and on the other hand frame 1.

  According to Figures 2 and 3, the sleeping surface 2 is equi

  pee on either side of removable lateral widening flaps 5.

  According to FIG. 2, these widening flaps extend over the entire sleeping surface 2 whereas, according to FIG. 3, they only extend along the central seat 2 and the backrest 2, and

  articulated wind between these two elements.

  According to Figure 5, the stretcher can be folded into a storage and transport position "vice" in a way that will

  described in more detail later in this talk.

  According to Figures 6 to 1O, the frame 1 of the stretcher bed is esentially constituted by two parallel beams 6 6 in aluminum profile extending on either side by telescopic handles 7 intended to be respectively gripped by two carriers, one of which is placed at one end of the stretcher-bed while the second is placed at

the other end of it.

  The two beams 6, 6 wind connected near their ends by two transverse bars 8 hinged to their part me

  diane around an axis of articulation 9.

  As a result, each of the transverse bars 8 consists of two bar sections 8, 82 articulated one on the other around the axis

hinge 9.

  These crossbar sections 8, 82 can be placed between on the one hand a position in which they wind located in the

  extension of one another to define a crossbar 8 rectili-

  gene as shown in FIGS. 6, 7 and 9 and on the other hand a posi-

  tion in which they are folded against each other around the hinge pin 9 in a V-shaped configuration as shown on the

o Figures 8 and 10.

  Locking members not shown in the figures

  allow to block the bar sections 8, 82 in these two posi-

  tions. When the respective bar sections 8, 82 are located in the extension of one another, the sleeping surface 2 is deployed as shown in FIG. 1 and the stretcher-bed is in the sleeping position. On the contrary, when the respective bar sections 8, 82 are folded against each other, the two beams 6, 62 are brought back one towards the other in close proximity to one another, and the sleeping surface 2 is folded back on itself. The stretcher-bed is then in

  the storage and transport position "a vice", shown in the figure

gure 5.

  Furthermore and according to FIGS. 7 and 8 when they wind in.: 5 low position, the four positioning feet 4 wind folded down two a

  two along a respective spar associate 6, 62, this in the same sees.

  In other words, two extension feet 4, 4 'vent ra-

  beaten along one of the side members 6 below it while the other two extension legs 42, 4'2 are folded down along the second side member 62, also below it, as shown

example in Figure 7.

  According to figure 6, each pair of extension feet 4, 4 '; 42, 4'2 is held in this position by a gas locking cylinder 101, 102 connected to an adjustment lever 11, 112, located below a poi

  gnee telescopique 7 associated, on one side of the stretcher bed.

  Safety devices not shown in the figures make it possible to exclude any accidental actuation of the blocking jacks

, 102.

  Given this configuration, to pass the

  extension feet 4 from the low position shown in Figure 7 at the

  high position represented on figure 6, the wearer located on the side of the ma-

  adjustment adjustment 11, 112 must slightly pull these upwards to

  s release the blocking cylinders 10, 102 and consequently order the rocker-

  extension legs 4 to the high position.

  To move the extension feet 4 from the high position to the low position, the carrier located on the side of the adjustment levers 11 and

  112 must perform the reverse operations while accompanying the

  oement of these feet 4 with the second carrier.
