Description

Field of the invention

[0001] The present invention aims at an operating frame intended to support a stretcher. State of the art

[0002] In the event of accidents, natural disasters, attacks or in times of war, wounded people are often transported to places where they can receive first aid on stretchers, which traditionally consist of two parallel poles connected by a fabric forming a bed.

[0003] These stretchers are then positioned in care facilities, hospitals, ambulances, or other means of transport where nursing staff can provide first aid, on various stretcher structures that are height-adjustable and / or proactively adjustable / tiltable to maintain a shock position if necessary.

[0004] A stretcher is disclosed in the American patent application US 2009 02 12 535 A1. Object of the invention

[0005] In this context, the present invention aims to propose a stretcher which, on the one hand, defines a positioning surface which, in the position of use, is substantially rectangular and horizontal and delimited at its corners by four support elements of a stretcher and, on the other hand, makes it possible to obtain an arrangement which, at the same time, ensures the safety of the patients or the wounded and, in particular, is light, robust and practical for the caregivers. Description and advantages of the invention

[0006] To this end, the invention relates to a support frame of the aforementioned type, wherein the support elements are formed by lugs with a transverse bore, which are fixed to the positioning surface, in particular by means of screws and comprising at their free end an elongated rest surface which, in the position of use, is substantially horizontal and machined so as to correspond to the circumference of a rod.

[0007] This resting surface can be adapted to round bars or square bars or have a mixed configuration that allows it to support all types of stretchers.

[0008] In the support frame according to the invention, the support lugs cooperate in pairs to support one of the bars of a stretcher along a longitudinal side of the positioning surface.

[0009] It should be noted that, in this description, the terms transverse, longitudinal... are to be understood as referring to a stretcher positioned on the carrying frame in the position of use.

[0010] Additionally, the positioning surface can be height adjustable and / or proactively adjustable / tiltable.

[0011] In order to provide the necessary care to the patients or wounded, it is essential that the nursing staff have access to various medical or surgical devices in close proximity to the stretcher.

[0012] Such medical or surgical devices are often attached to lateral operating rails rigidly connected to the support frame by means of clamps or other elements such as straps of adapted size, resulting in heavy devices that are inconvenient to handle and lack flexibility.

[0013] To overcome this drawback, the support frame according to the invention is provided with two lateral operating rails extending on both sides of the positioning surface along the longitudinal sides thereof and each removably fixed to said frame in a mounting position by means of two transverse fixing pins located at a distance equal to the distance between the two support lugs of a pair and fitting into the transverse bore of a connected support lug.

[0014] The side operating rails are of course height adjustable and / or proactively adjustable / tiltable together with the positioning surface if required.

[0015] These lateral operating rails, which are attached to the support frame only by two fixing points in the support lugs, can advantageously be formed by profiles, in particular made of stainless steel with a cross-section of 25 x 10 mm.

[0016] The support frame according to the invention thus has the advantage of corresponding to a particularly practical and lightweight structure which can be assembled and disassembled in a very simple and rapid manner without the need for tools.

[0017] According to a further feature of the invention, the fixing pins are fixed integrally to the associated operating rail, in particular screwed thereto at one of its ends or its first end, and have at their free end or their second end movable stop elements which allow their blocking in the engaged position in the transverse bore of the extension of the associated support.

[0018] Such stop elements can simply be formed by a bolt that cooperates with a hole in the fastening pin in the end position.

[0019] However, the stop elements are advantageously formed by at least one elastically mounted ball which is movable between an inserted position and a retracted position and cooperates with a push button which enables its actuation.

[0020] For example, according to such a configuration, when the push button is pressed, the ball may enter the fixing pin in the retracted position, thereby allowing the fixing pin to slide into the transverse bore of the support boss.

[0021] When the push button is released at the end, the ball comes out of the fixing pin in the inserted position and thus blocks this pin outside the support lug.

[0022] The assembly and disassembly of the operating rails is therefore particularly quick and easy.

[0023] According to a further feature of the invention, the fastening pins comprise at their first end a spacer sleeve fitted thereon, which makes it possible to define a gap between the operating rails and the support lugs in the mounted position.

[0024] These spacers, which in the mounted position are located between the operating rail and the corresponding support attachment, allow the mounting of medical or surgical devices on the operating rails thanks to the gap they define.

[0025] Preferably, the fixing pins are provided with a thread at one of their ends to allow them to be screwed onto an operating rail, and the spacer sleeves are also screwed onto this thread.

[0026] According to a preferred feature of the invention, the operating rails each consist of at least three rail segments, preferably of substantially the same length, which can be moved by simply sliding them, and without the need for any tool, relative to each other, on the one hand, between a storage position in which they are independent of each other and, on the other hand, a use position in which they are assembled along a straight line of a length close to that of the bars of a stretcher, namely a central rail segment and two lateral rail segments, each comprising a fixing pin rigidly attached thereto.

[0027] According to the invention, each rail segment advantageously consists of a rectilinear element, preferably having a substantially rectangular section and provided at at least one of its ends with a mounting lug that can cooperate by positive connection with a mounting lug that has a similar configuration but is oriented symmetrically to another rail segment to enable assembly by nesting these two rail segments.

[0028] According to the invention, the mounting lugs preferably each consist of a shoulder and of a bracket having a substantially U-shape and being fixed to the rail segment, in particular being screwed thereon, overlapping part of its periphery and extending at the level of the shoulder to define a male plug element and a female plug element which are adjacent.

[0029] After being detached from the support lugs, the operating rails can be dismantled very easily and quickly by simply loosening the mounting lugs from the rail segments.

[0030] According to a preferred variant of the invention, the support frame consists of a box mounted on wheels to make it possible to obtain a trolley support frame and comprising an open area defining the positioning surface and allowing access to its interior, which forms a storage volume capable of containing the operating rail segments in the storage position.

[0031] According to this configuration, the support lugs of a pair can be attached to a longitudinal edge of the open surface of the box that defines the positioning surface.

[0032] This is a particularly advantageous variant of the invention.

[0033] In fact, especially in the event of accidents, natural disasters or attacks, or in war zones, injured people can be quickly evacuated and transported on the stretcher to a care facility, such as a military or civilian hospital tent or an ambulance, or in an emergency, even receive first aid or minor surgery on the spot.

[0034] According to a further advantageous feature of the invention, the wheels of the trolley support frame are removable and the box consists of a housing comprising two articulated shells around a hinge in order to be able to be moved between, on the one hand, an open V-position or use position and, on the other hand, a closed position or storage and transport position in which several housings can be stacked.

[0035] Such shells can, for example, be made of glass-fiber reinforced polyester, which makes them particularly robust.

[0036] According to such a configuration, the rollers are advantageously removable and, when disassembled, can be stored in the housing and a central latch guarantees the open V-position thereof.

[0037] Medical or surgical devices (serum containers, aprons to protect against contamination, etc.) can also be stored in the housing.

[0038] In addition, two articulated frames, located on either side of the box, can be inserted and blocked outwards to form support feet and obtain an M-confirmation.

[0039] Each of the articulated frames thus forms two support feet.

[0040] It should be noted that the support feet can advantageously be formed by telescopic rods with integrated catches and springs so that their height can be regulated independently and the horizontal position can be adjusted even on uneven ground and to obtain a proactive / up to 9 ° inclined position if necessary.

[0041] With such an adjustment, the wheels finally no longer touch the ground and the operating rails always remain along the stretcher, thus avoiding the need to change the patient's position, especially to perform an operation.

[0042] After surgery, the feet can be unlocked so that the wheels finally touch the ground again, and the trolley can be moved with the patient to a recovery room if necessary, with the medical or surgical devices always attached to the rails... Description of the drawings

[ Fig. 2] is a perspective view, which Fig. 1 and represents the operating rails positioned opposite the support lugs, [ Fig. 3] illustrates the adjustment of the support feet of the trolley support frame, [ Fig. 4] a sectional view of a detail from Fig. 1, which represents a fixing pin positioned in a support lug, [ Fig. 5] is an exploded view of a positioning rail, [ Fig. 6] is an illustrative diagram of the arrangement of the rail segment lugs. Description of an embodiment of the invention

[0044] According to Fig. 1, Fig. 2 and Fig. 3, the trolley carrying frame consists of a box 1 consisting of two joint shells 2, 3 around a hinge 4 and which can be opened in a V-shape in a position of use shown in the figures.

[0045] The box 1 is mounted on the wheels 5 and comprises an open surface 6 defining a positioning surface of a stretcher 7 consisting of two parallel bars 8, 8' connected by a fabric 9 forming a bed.

[0046] The box 1 further comprises two articulated frames 10, 10' on both sides thereof and which can be inserted and blocked outwards as shown in the Fig. 1 to 3 to form support feet 11 and thereby obtain an M configuration.

[0047] According to Fig. 3, the support feet 11 are formed by telescopic rods which allow their independent adjustment in height and the adjustment of the inclination of the positioning surface 6 and the stretcher 7.

[0048] According to Fig. 1, Fig. 2 and Fig. 3, the positioning surface 6 has a substantially rectangular shape and is delimited at its corners by four support lugs 12 which cooperate in pairs to support one of the rods 8, 8' of a stretcher 7 along a longitudinal side of this positioning surface 6.

[0049] According to Fig. 4, each of the support lugs 12 is fixed by means of screws 13 to a longitudinal edge 14 of the open surface of the box 1, which defines the positioning surface and comprises at its free end an elongated rest surface 15 machined to correspond to the circumference of a rod 8, 8' of a stretcher 7.

[0050] The support lugs 12 are also provided with a transverse bore 16, the function of which will be explained later in this description.

[0051] According to Fig. 1, Fig. 2 and Fig. 4, the trolley support frame 1 is provided with two lateral operating rails 17 extending on both sides of the positioning surface 6 along the longitudinal sides thereof and each removably attached to the box 1 in the mounting position shown in the figures, in a manner that will be described in more detail later in this description.

[0052] According to Fig. 5, the operating rails 17 each consist of three rail segments 171, 172, 173 which have substantially the same length, namely a central rail segment 171 and two lateral rail segments 172, 173, each comprising a transverse fastening pin 18 which is screwed thereon.

[0053] The rail segments 171, 172, 173 can be moved relative to each other between a storage position in which they are independent of each other and a use position which is Fig. 1 and Fig. 2, in which they are assembled along a straight line with a length close to that of the bars of a stretcher.

[0054] In the use position, the fastening pins 18 of the two lateral rail segments 172, 173 of an operating rail 17 are at a distance equal to the distance between the two support lugs 12 of the associated pair and can each fit into the bore 16 of a support lug 12, as shown in the Fig. 2 and Fig. 5 shown.

[0055] According to Fig. 4, the fixing pins 18 comprise at their free end stop balls 19 which are mounted elastically and movably between an inserted position and a retracted position so that they can be inserted into the bore 16 of the associated support lug 12 and blocked at the end of the movement in the mounting position in which the fixing pin 18 is engaged in the bore.

[0056] A push button 20, which is shown schematically in Fig. 4, allows the movement of the stop balls 19 between the inserted position and the retracted position.

[0057] According to Fig. 4 and Fig. 5, the fastening pins 18 further comprise a spacer sleeve 21 fitted thereon, which allows a gap to be maintained between the operating rails 17 and the support lugs 12 in the mounted position, as shown in Fig. 4 to enable the mounting and fastening of medical or surgical devices not shown in the figures to the operating rails 17.

[0058] According to Fig. 5 and Fig. 6, each rail segment 171, 172, 173 consists of a rectilinear element having a rectangular cross-section and equipped at one of its ends (lateral rail segments 172, 173) or at its second ends (central rail segments 171) with a mounting lug 22 which can cooperate by means of a positive connection with a mounting lug 22' having a similar configuration but arranged symmetrically around another rail segment 171, 172, 173 to allow assembly by nesting these two rail segments, as shown schematically in Fig. 6 shown.

[0059] According to Fig. 5 and Fig.6, the mounting lugs 22, 22' each consist of a shoulder 23 and of a U-shaped bracket 24 which is fixed to the rail segment 171, 172, 173, connected by means of screws 25, overlapping part of its circumference and extending at the level of the shoulder 23.

[0060] The mounting lugs thus define a male plug element 26 and a female plug element 27, which are adjacent, at the level of the shoulder 23.
