Description

The present invention relates to a rapid evacuation module for first aid.

The technical sector of the invention is the field of the production of means of transport and accessories for the sick.

The main application of the invention is in fact to be able to evacuate quickly and in the first emergency of the wounded identified on the sites of accidents or natural disasters, especially when access by pre-equipped emergency vehicles for first aid and Transport is not directly and / or immediately possible: in particular, an important application of the invention is the evacuation of victims during accidents on railways, such as for trains and especially the metro.

Indeed, if an accident occurs for example inside a structure, such as in the metro galleries or in tunnels, it is not possible that an ambulance or of course a helicopter can come to recover there directly the stretchers on which rescuers install the injured: to date, the only solution is then to transport these stretchers by human arm to a site accessible by emergency vehicles, which requires at least two people to carry the stretcher, if not four if the injured person is heavy, and even one more person in the event of an infusion to hold the corresponding bottle; in addition to the fact that it is therefore necessary to find and send a large number of assistance people, their simultaneous presence at the accident site and on the access roads slows down the effectiveness of the emergency services all the more, especially on a site of difficult access; there is also the risk due to the portage during this transport by arm, and the impossibility apart from the infusion then to ensure first aid care on such stretchers.

The problem is therefore to be able to transport and evacuate by stretcher or stretcher the injured, sick or accident victims from the site where they are, especially when access to this by pre-equipped emergency vehicles or other specialized means of transport for this, is not possible directly and / or immediately, and up to these so-called vehicles or to other sites, on which intervention facilities of a surgical or other type have been installed to treat said injured, sick or victims: said transport and / or evacuation must be able to be carried out with a minimum of assistance persons during the journey, reducing the risk of shock and / or overturning of the stretcher or the stretcher, in a minimum of time and with means easy to implement.

One solution to the problem posed is an evacuation module comprising a foldable chassis consisting of at least two parts provided with supports capable of receiving at least one removable stretcher, said chassis comprising two parallel cross members each carrying a sufficient number of supports to receive at least two stretchers side by side and an infusion stand, at least one central connecting bar between the two said crosspieces and which is separable from them, and at least four wheels fixed two by two under each crosspiece.

Modular and foldable stretcher supports are known for transporting them, but either they are devices for transporting only one stretcher at a time, in order to be able to bring the latter inside the '' an ambulance type vehicle, and in which said device must be able to fold away for easy accommodation, as described for example in patent application FR 2493142 published on May 7, 1982, or supports for several stretchers at the same time then adaptable to transport in a rescue van, as described in patent application FR 2603478 published on March 11, 1988.

Such systems, even if they are made up of different removable and foldable parts, do not make it possible to respond to the problem posed, since they are adapted and precisely require being associated with a van or vehicle for transporting injuries for stay inside, while on the contrary the problem posed and solved by the present invention, is to provide transport to such vehicles without of course requiring that said support or transport module can enter this vehicle .

The objectives of the present invention are therefore very different from those of existing systems and the technical and specific means enabling these objectives to be achieved are also, both in the basic structure and in the additional elements which are also the subject of the invention. 'invention.

In particular, in a preferred embodiment, each cross member of the evacuation module according to the invention comprises at least one oxygen cylinder support preferably placed on gusset plates which are integral and mounted in the middle of each cross member and on which are detachably fixed the ends of said central bar connecting said crosspieces; similarly, each cross member may comprise at each of its ends at least one attachment point capable of allowing said module to be lifted by its four angles, then allowing evacuation by helicopter.

In order to allow first aid medical treatment such as in the event of cardiac discomfort, said removable stretchers are made of rigid material constituting a hard surface such as for example aluminum with folded edges, for rigidity while giving a certain lightness. .

• ledit module suivant l'invention pouvant comporter au moins une barre de traction amovible et s'articulant au milieu de l'une desdites traverses dans l'axe de la barre centrale, ainsi qu'une barre d'attelage disposée de la même façon mais sur l'autre traverse par rapport à celle portant ladite barre de traction, afin de pouvoir atteler d'autres modules les uns derrière les autres, une seule personne peut alors tracter, à pied ou par tout moyen mécanique ou automoteur tel que par énergie électrique ou un moteur thermique, un ou plusieurs brancards attelés en train les uns derrière les autres ;
• les roues qui équipent le module suivant l'invention permettent le déplacement de celui-ci essentiellement sur des rails dans l'application au métro ou au train, mais également sur tout type de sol avec tout type de roues adaptées pour cela ;
• le système étant démontable en éléments longitudinaux de section relativement faible, et pliable alors dans un faible encombrement, on peut ainsi le stocker en tout lieu en un emplacement réservé pour cela, ou on peut l'amener de l'extérieur sur le site dans deux sacs de rangement par exemple, au moment voulu, où il est alors facilement montable ;
• le système étant très léger s'il est réalisé uniquement en matériau de type aluminium, cette légèreté permet d'autant plus son transport facilement sur tout site souhaité ;
• les civières suivant l'invention peuvent être réalisées en tout matériau créant un plan dur, celui-ci permettant de pouvoir effectuer par exemple un massage cardiaque sur la personne qui est allongée sur ladite civière, mais d'autres civières de tout type, adaptées aux fixations et supports du châssis, peuvent être utilisées,
• la rigidité de l'ensemble du système une fois assemblé, permet son évacuation par hélicoptère, grâce aux points d'attache disposés pour cela ;
• enfin, divers accessoires peuvent être rajoutés en plus de ceux déjà cités précédemment, tels qu'au moins deux pieds de perfusion situés dans le même plan médian que la barre centrale, avec un support de bâche reliant d'une manière démontable les deux extrémités supérieures de ces deux pieds de perfusion, afin de protéger les personnes situées sur les brancards, jusqu'à ce qu'on puisse les évacuer vers un centre d'accueil ou de traitement ; ainsi que divers supports tels que pour des lampes d'éclairage solidaires chacune d'un desdits pieds de perfusion pour, d'une part pouvoir éclairer le chemin vers lequel le module est transporté, et d'autre part les malades ou blessés installés sur les civières.

The result is a new rapid evacuation module for first aid responding to the problem posed and having many advantages such as those mentioned above, as well as:

• said module according to the invention may include at least one removable drawbar and articulated in the middle of one of said crosspieces in the axis of the central bar, as well as a drawbar arranged in the same way but on the other crosspiece with respect to that carrying said drawbar, in order to be able to couple other modules one behind the other, a single person can then tow, on foot or by any mechanical or self-propelled means such as by electrical energy or a heat engine, one or more stretchers hitched in train one behind the other;
• the wheels fitted to the module according to the invention allow the displacement thereof essentially on rails in the application to the metro or to the train, but also on any type of ground with any type of wheels suitable for this;
• the system being removable in longitudinal elements of relatively small section, and then foldable in a small size, it can thus be stored anywhere in a location reserved for this, or it can be brought from the outside to the site in two storage bags for example, at the desired time, where it is then easily mountable;
• the system being very light if it is made only of aluminum type material, this lightness allows all the more its transport easily on any desired site;
• the stretchers according to the invention can be made of any material creating a hard plane, this making it possible to be able to carry out, for example, a cardiac massage on the person who is lying on said stretcher, but other stretchers of any type, suitable for chassis fixings and supports, can be used,
• the rigidity of the whole system once assembled, allows its evacuation by helicopter, thanks to the attachment points arranged for this;
• finally, various accessories can be added in addition to those already mentioned above, such as at least two infusion stands located in the same median plane as the central bar, with a tarpaulin support that can be dismantled connecting the two upper ends these two infusion stands, to protect the people on the stretchers, until they can be evacuated to a reception or treatment center; as well as various supports such as for integral lighting lamps each of one of said infusion stands for, on the one hand being able to illuminate the path towards which the module is transported, and on the other hand the sick or wounded installed on the stretchers.

We could cite other advantages of the present invention, but those mentioned above already show enough to prove its novelty and interest.

The description and the single Figure below present an example of an embodiment of the invention but are in no way limiting: other embodiments are possible within the scope and scope of this invention.

The attached single figure represents a perspective view of a discharge module according to the present invention with its basic structure and all of the removable elements which can be fitted to said structure and which are shown in the disassembled position.

The evacuation module indeed comprises a foldable frame 1, consisting of at least two parts, provided with supports 15 which can receive at least one removable stretcher 3, said frame 1 comprising two parallel cross-pieces 17 each carrying a sufficient number of supports 5, 15 to receive at least two stretchers side by side and an infusion stand 4, at least one central bar 2 for connection between the two said sleepers and which is separable from them, and at least four wheels 13 fixed two by two under each cross 17.

Said chassis 1 preferably comprises at least two gusset plates 16 integral and mounted in the middle of each cross member 17 and on which the ends of said central bar 2 are detachably fixed.

The dismantling and coupling of this central bar with the crosspieces is carried out by any known quick fixing system, such as for example safety pins which, once put in place, can no longer be removed without intervention with a tool specific: this fixing and coupling of the central bar is done by any interlocking and immobilization device such as for example in a sheath fixed on the gusset plate 16 of each cross member 17 and following, ie at least one quick-fixing stud and safety device passing through each of its ends through the two said gusset plates 16, either by a toggle system with a locking hooking tab between said central bar 2 and the gusset plates 16, or by any other means with more preferably a pin security pin, such as that for carrying the bottle holder 6 described below. These gusset plates 16 can be doubled and made in the form of a box for sandwiching said central bar 2 and are preferably of triangular shape, a base of which is fixed along said crosspieces 17 and receives at its ends a stretcher support 15.

These stretcher supports 15 may be in the form of rectangular studs in which, or around which, other studs are housed vertically then cooperating with them and integral with said stretchers, in order to immobilize them in the horizontal plane.

These removable stretchers 3 can be made of rigid material constituting a hard surface with lateral handles allowing their carrying, and equipped with removable transverse straps 14 for allow to keep the victims or the wounded on said stretchers.

Each cross member 17 also comprises at least one support 6 for an oxygen cylinder which is also removable and fixed by any known system of quick coupling through, for example the gusset plates 16 allowing the fixing and / or ensuring the security of this fixing the central bar 2.

Likewise, each cross member 17 comprises at least three supports 5 of infusion stands 4 at each end and one in the middle of each of said cross members 17: these supports 5 can be produced as for the stretcher supports in the form of hollow cylindrical studs, in which the infusion feet 4 are housed and are immobilized by any known rapid unlocking system such as for example safety pins.

Said perfusion feet 4 may also include a lamp support 7 for lighting, in addition to the supports for the perfusion bottles themselves, generally arranged in the shape of a cross with respect to the foot itself.

In a preferred embodiment, the module according to the invention comprises at least two infusion stands 4 situated in the same median plane as the central bar 2 and a tarpaulin support 10 which itself can be folded into two articulated parts and once unfolded releasably connecting the two upper ends of these two infusion stands 4.

each cross member 17 also comprises at each of its ends at least one attachment point 8 capable of allowing said module to be lifted by its four angles, by means of four winching straps then allowing in particular its evacuation by helicopter and that the can be fixed by shackles or snap hooks in holes made in said attachment points 8 to the desired diameter for this. Said attachment points 8 may also each comprise a lifting arm handle for moving the module on the ground, such as for example for a lane change in applications for evacuating victims during accidents on railways: these handles are of suitable shape of any type known to allow gripping by hand.

To allow the displacement in the horizontal plane of said module, it comprises, as indicated above at least four wheels which are to be adapted to the running surface on which the displacement will take place, such as wheels with lateral flanges to be able roll on rails, the roller itself can be made of any type of material hard enough for this such as black nylon for example and laterally fitted with ball bearings, as well as at least for one of them, of any brake system known to be able to immobilize said module at any desired location.

To ensure the movement itself, the module comprises at least one removable pull-up bar 11 and which is articulated in the middle of one of said crosspieces in the axis of the central bar 2 and which then becomes the front crosspiece of the module, whereas a removable drawbar 12 can be articulated in the middle of the other so-called rear cross member, also in the axis of the central bar so as to be able to couple other modules one inside the other, as already indicated above.

Various other equipment can supplement said module, such as in particular a storage bag 9 in which the various removable parts can be accommodated, such as the tarpaulin and its support 10, but also any first aid material for example, said bag being able to attach to the central bar 2 or to one of the stretchers 3.

The actual structure of the chassis can be made of aluminum tubes of section for example 50 millimeters X 100 millimeters with a thickness of 2.5 millimeters for 1,800 millimeters in length corresponding to the width of the module with regard to the crosspieces. ends 17 and in tubes of section 50 millimeters X 50 millimeters thick 2 millimeters fitted to increase rigidity and flexural strength on another tube of square section 40 X 40 millimeters and thickness 2 millimeters throughout its length which can be approximately 1,125 millimeters for the central bar 2. Each end of the latter then preferably fits over 195 millimeters between the two plates of the gussets 16 of each cross member 17 and is made up for example in aluminum sheet folded and welded in the form of a box with a thickness of 2 to 3 millimeters.

The whole of such a module produced with aluminum elements according to the example of the dimensions above, weighs around 60 kilos and can be dismantled and stored in two suitcases which are then each transportable by a single person. thanks for example to a strap for carrying over the shoulder: the dimensions of these so-called suitcases could be, taking into account the dimensions of the elements given above with additional information on the height of the module of 320 millimeters corresponding in fact to the height end cross members 17 due to the presence of the wheels 13 which are integral with them, can be of dimensions 820 millimeters high and 1,800 millimeters long for each and 240 millimeters wide for one and 320 millimeters for l 'other.
