Description

The invention relates to the field of medical beds, and more particularly to barriers for medical beds.

Medical beds are used both in hospitals, nursing homes, and patients' homes.

Medical beds have been developed to meet the specific needs of patients, depending on the pathologies they present. Thus, medical beds are intended to relieve patients by facilitating for example the change of position, the dispensation of care or taking medication.

Medical beds also preferably allow easier access to the patient by the staff providing the care.

• des roulettes pour faciliter le déplacement du lit,
• un système d'élévation du sommier, pour aider le patient à monter et à descendre du lit,
• une potence sur laquelle le patient peut tirer pour se repositionner seul,
• un système permettant de relever le dossier, les pieds, ou le dossier et les pieds, du sommier.

Thus, the medical beds include a whole equipment offering different functionalities to adapt to the patient, for example:

• casters to facilitate moving the bed,
• a mattress lift system, to help the patient get on and off the bed,
• a stem on which the patient can pull to reposition themselves alone,
• a system to raise the backrest, feet, or backrest and feet, of the bed.

The beds may further include barriers, preventing the patient from falling. The barriers are generally placed on either side of the sleeping surface, and may extend over all or part of the length of the bed.

Three types of barriers are generally encountered.

The first type is the simple barrier, extending over the entire length of the bed. The document DE 20 2004 017 406 (BOCK) describes an example of such a barrier.

It is known to report this type of barrier on the bed, depending on whether the patient who is intended for the bed needs it or not.

The second type is the three-quarter barrier, extending over only a portion of the length of the bed.

The third type is the half-barrier that allows to use two barrier panels, or half-barrier, independently. Specifically, each panel is mounted on one side of the bed, and can for example be lowered while leaving the other panel in place. Thus, it is for example possible to lower the barrier panel placed at the patient's head while leaving in place the panel placed at the level of the feet. Access to the patient to provide care is then easier, while maintaining a safety vis-à-vis the falls. Similarly, it is possible to lower the feet panel and leave in place the head panel, so that the patient can get out of bed while using the head board.

Thus, half-barriers are particularly used in hospitals.

There are different barriers having two panels, head and feet, which can be retracted relative to the sleeping surface on the bed independently of one another.

The document US 2006/0195984 (HILLROM) presents an example of such a barrier, comprising two panels, placed on each side of the bed. Each panel is fixed on the bed in a specific position, and is retractable by rotation about a longitudinal axis.

The document EP 1 970 038 (SCHELL) describes a barrier operating on a principle similar to that of the document US 2006/0195984 supra.

The document US 2008/0127415 (HILLROM) describes a barrier comprising two panels fixed independently of one another on the bed, retractable by rotation about a transverse axis.

There are normative requirements, for example given by the IEC 60601-2-52 standard, regulating the spacing between the half barriers. To obtain a bed conforming to the standards, the barrier panels are conventionally fixed with a spacing, and are not intended to be removed, the barriers in two panels of the state of the art being integrated into the frame of the bed , to be fixed permanently on the bed.

A first object of the invention is to provide a bed barrier comprising two independent panels, which can be easily removed. of the bed and assembly again while respecting a determined spacing between the panels.

A second object of the invention is to provide a bed barrier comprising two panels, the barrier can be easily mounted and disassembled from the bed.

A third object of the invention is to provide an easily transportable bed barrier.

A fourth object of the invention is to provide a removable bed barrier that disassembles and mounts with minimal effort.

A fifth object of the invention is to provide a removable bed barrier facilitating access to the patient, while giving the patient autonomy to get out of bed.

According to a first aspect, the invention proposes a bed barrier, in particular a medical bed, comprising a support arm provided with fixing means on a spar of the bed, the barrier also comprising a first panel, referred to as a front panel, in connection with with the support arm, the support arm further having a front section and a rear section. The barrier comprises a second panel said rear panel and in that the front panel is in connection with the front section of the arm and the rear panel is in connection with the rear section of the arm.

The barrier thus formed makes it possible to combine the advantages of a barrier with those of two half-barriers, while respecting the barrier standards for hospital beds.

• une position relevée dans laquelle les montants sont perpendiculaires au barreau,
• une position escamotée dans laquelle les montants sont parallèles au barreau.

According to one embodiment, the front panel comprises two parallel uprights, each pivotally mounted on the front section of the support arm, the two uprights being connected by at least one bar pivotally mounted on each upright, the front panel being deformable according to a parallelogram deformable between:

• a raised position in which the uprights are perpendicular to the bar,
• a retracted position in which the amounts are parallel to the bar.

The raised position of the front panel ensures the safety of a patient lying on the bed, while the retracted position allows medical personnel to access the patient on the bed and provide the necessary care.

• une position relevée dans laquelle les montants sont perpendiculaires au barreau,
• une position escamotée dans laquelle les montants sont parallèles au barreau.

Also, the rear panel may comprise two parallel uprights, each pivotally mounted on the rear section of the support arm, the two uprights being connected by at least one bar pivotally mounted on each upright, the rear panel being deformable according to a deformable parallelogram between:

• a raised position in which the uprights are perpendicular to the bar,
• a retracted position in which the amounts are parallel to the bar.

The raised position of the back panel ensures the safety of a patient lying on the bed, while the retracted position allows the patient to get out of bed while keeping the front panel in the raised position.

Preferably, the fastening means are clamping jaws, allowing a single operator to easily assemble and dismount the barrier without tools.

Thus, for example, the front panel is mounted on a first jaw integral with the front section of the support arm, the rear panel being mounted on two jaws integral with the rear section of the support arm.

Alternatively, the front panel is mounted on a first jaw integral with the front section of the support arm, the rear panel being mounted on a single jaw secured to the rear section of the support arm.

• une position déployée, dans laquelle la section avant est dans le prolongement de la section arrière,
• une position pliée, dans laquelle la section avant est rabattue contre la section arrière.

According to a preferred embodiment, the front section of the support arm is pivotally connected to the rear section of the support arm, so that the support arm can take two positions:

• an extended position, in which the front section is in the extension of the rear section,
• a folded position, in which the front section is folded against the rear section.

In the deployed position, the barrier is then used on the bed. The folded position facilitates both storage and transportation by reducing the size of the barrier.

For example, the front section is rotated about a first axis on a first end portion of a spacer and the rear section is rotated about a second axis, parallel to the first axis, on a second end portion. of the spacer.

The spacer thus makes it possible to fold the portions of the arm towards one another, being substantially parallel to one another, without the sections overlapping.

• mise en position pliée de la barrière de lit,
• fixation de la section avant du bras sur le longeron,
• mise en position déployée de la barrière de lit,
• fixation de la section arrière du bras sur le longeron.

According to a second aspect, the invention proposes a method of mounting a bed barrier as described above on a bed comprising at least one spar, the method comprising the following steps:

• placing in the folded position of the bed barrier,
• fixing the front section of the arm on the spar,
• placing in the deployed position of the bed barrier,
• attaching the rear section of the arm to the spar.

By first fixing the front section, then in a second time the rear section, the assembly is facilitated because the number of fasteners to be implemented at the same time on the spar of the bed is reduced.

According to a third aspect, the invention provides a bed, in particular a medical bed, comprising an upper frame defining a sleeping surface and comprising a spar, and comprising a barrier as described above fixed on the spar.

The functions of the bed can thus be adapted to the needs of the patient, by mounting or dismounting the barrier of the bed.

Other objects and advantages of the invention will become apparent in the light of the description given hereinafter with reference to the appended drawings in which:

• the figure 1 is a perspective view of a bed barrier comprising two panels, in a folded position;
• the figure 2 is a perspective view of the barrier of the figure 1 in a deployed position;
• the figure 3 is a perspective view of a bed, including a medical bed and the barrier of the figure 1 in a first assembly position;
• the figure 4 is a view similar to that of the figure 3 the bed and the barrier being in a second assembly position;
• the figure 5 is a view similar to that of the figure 4 the bed and the barrier being in a third assembly position;
• the figure 6 is a view similar to that of the figure 5 , the bed and the barrier being in a fourth, and last assembly position;

• the figure 8 is a view similar to that of the figure 7 wherein the other panel is in a retracted position;
• the figure 9 is a view similar to that of figures 7 and 8 wherein both panels are in a retracted position.

On the figures 1 and 2 is represented a bed barrier 1 comprising two panels 2, 3, called front panel 2 and rear panel 3, connected to a support arm 4.

Per panel, it is designated a guardrail element of the barrier, preventing a patient of the bed from falling.

Thus, the panels 2, 3 can be solid panels, perforated panels, lattice panels, or panels formed of bars

• une position déployée dans laquelle la section 5 avant est sensiblement dans le prolongement de la section 6 arrière (figure 2), et
• une position pliée, dans laquelle la section 5 avant est rabattue contre la section 6 arrière (figure 1).

The support arm 4 comprises two sections 5, 6, called front section 5 and rear section 6, distinct from each other. The front section 5 extends from a first end of the support arm 4 and is extended by the rear section 6 to the second end of the support arm 4. Preferably, as will be seen later, the front section 5 is in pivot connection with the rear section 6, so that the barrier 1 can take two positions:

• an extended position in which the front section 5 is substantially in the extension of the rear section 6 ( figure 2 ), and
• a folded position, in which the front section is folded against the rear section 6 ( figure 1 ).

Preferably, in the deployed position, the front section 5 abuts the rear section 6.

According to the preferred embodiment, the support arm 4 comprises a spacer 9 connecting the front section and the rear section. More specifically, the front section 5 is pivotally mounted on a first end portion of the spacer 9 relative to a first axis and the rear section 6 is pivotally mounted on the second end portion 11 of the spacer 9 relative to a second axis parallel to the first axis.

The spacer 9 thus allows, when the barrier 1 is in the deployed position, to keep the two sections 5, 6 at the same height relative to their axes of rotation on the spacer 9. In addition, in the folded position, the two sections 5, 6 may be substantially parallel to each other, despite the presence of the panels 2, 3 carried by the sections 5, 6.

The front panel 2 is in connection with the front section 5 of the support arm 4 while the rear panel 3 is in connection with the rear section 6 of the support arm 4.

The term "connected with" here refers to the characteristic that there is at least one bond between two bodies, in this case between a panel 2, 3 and a section 5, 6.

More specifically, according to a preferred embodiment, the front panel 2 comprises a first link 12 on the front section 5 and the rear panel 3 comprises a second link 13 and a third link 14 on the rear section 6, the third link 14 being closer to the second end 8 of the support arm 4 than the second link 13. The number of links of each panel 2, 3 on a section 5, 6 of the support arm 4 may however be adapted according to the design needs.

Due to the fact that each panel 2, 3 is in connection with a section 5, 6 distinct from the support arm 4, the connection of the front panel 2 to the front section 5 of the support arm 4 is separated from the connection of the panel 3 rearward on the rear section 6 of the support arm 4, that is to say a distance determined during the design of the barrier 1 can be measured between each link of the front panel 2 on the support arm 4 and each rear panel link 3 on the support arm 4, measured along the support arm 4 when the barrier 1 is in the deployed position.

For example, according to a preferred embodiment, when the barrier 1 is in the deployed position, the two panels 2, 3 are not in contact with each other, and a spacing in the direction of the support arm 4 in deployed position can be measured, corresponding to the distance between the first link 12 and the second link 13.

The barrier 1 further comprises means 15 for attachment to a beam 37 of the bed, carried by the support arm 4. According to a preferred embodiment, the fixing means 15 are integral with the support arm 4, and the panels 2, 3 are in connection with the fixing means 15. Advantageously, the fixing means 15 are removable means, that is to say that they can be easily disassembled and assembled on the bed, preferably without tools.

For example, the fixing means 15 are in the form of jaws 16 adjustable by means of a handle 17 that can be manually operated. The blocking of the barrier 1 on the bed can thus be obtained by clamping the jaws 16. The mounting of the barrier 1 on the bed will be described with greater precision later.

More specifically, each panel 2, 3 is for example in the form of a substantially planar element, that is to say that it has larger dimensions in two directions than those in the third direction. It can thus for example be a solid panel, or a trellis.

According to a preferred embodiment, each panel 2, 3 comprises two uprights 18 connected by at least one bar 19. In practice, the uprights 18 are connected by a series of parallel bars 19, for example three bars 19.

• X2, Y2 et Z2 les directions définies sur le panneau 2 avant,
• X3, Y3 et Z3 les directions définies sur le panneau 3 arrière.

For the following description, it is defined for each panel 2, 3 a vertical direction Z and a longitudinal direction X, included in the plane of the panel, and a transverse direction Y, perpendicular to the plane of the panel 2, 3. A for simplification purposes Note:

• X2, Y2 and Z2 the directions defined on the front panel 2,
• X3, Y3 and Z3 the directions defined on the rear panel 3.

Each upright 18 is in the form of a bent tube, comprising a straight portion. The front panel 2 comprises an upright 18 of which a lower end portion 21 is pivotally mounted on the front section 5 of the support arm 4 about an axis parallel to the transverse direction Y2 of the front panel 2 to form the first link 12 while the two uprights 18 of the rear panel 3 have a lower end portion 21, both of which are pivotally mounted on the rear section 6 of the support arm 4 about axes parallel to the transverse direction Y3 of the rear panel 3 to form respectively the second connection 13 and the third link 14.

More specifically, according to one embodiment, each link 12, 13, 14 is carried by a jaw 16 integral with the support arm 4, two jaws 16 being fixed on the rear section 6 and a jaw 16 being fixed on the front section 5. . However, a single jaw 16 fixed on the rear section 6 may suffice, so that a connection, for example the third link 14, of the rear panel 3 on the arm is then directly carried out on the rear section 6 of the arm 4.

The two uprights 18 of the rear panel 3 are then respectively mounted on one of the jaws 16 of the rear section 6, each pivoting about an axis parallel to the transverse direction Y3 of the rear panel 3, to form the second connection 13 and the third link 14.

A single upright 18 of the front panel 2 is mounted on the jaw 16 of the front section 5, pivoting about an axis parallel to the transverse direction Y2, to form the first link 12. Preferably, the lower end portion 21 of the second 18 amount of the front panel 2 is also mounted on a fourth jaw 16, which may however not be secured to the support arm 4.

The links 12, 13, 14 of the panels 2, 3 on the support arm 4 are shown in FIG. figure 2 by the transverse axis of rotation of the panels 2, 3 on the jaws 16.

The spacing between the first link 12 and the second link 13 may advantageously be determined so that the panels 2, 3 do not overlap and the amount 18 of the front panel 2 mounted on the first link 12 is at a distance from the post 18 of the adjacent rear panel 3, mounted on the second link 13.

In addition, for each panel 2, 3, the bar 19 connecting the two uprights 18 must advantageously be substantially parallel to the longitudinal direction X2, X3. Similarly, for each panel 2, 3, the jaws 16 must be aligned in the longitudinal direction X2, X3. Finally, for each panel 2, 3, the straight portions 20 of the two uprights 18 of each panel 2, 3 are arranged so as to be substantially parallel to each other.

• une position relevée, dans laquelle la portion 20 droite des montants 18 est sensiblement perpendiculaire aux barreaux 19 (en traits pleins sur la figure 2), c'est-à-dire sensiblement parallèle à la direction Z2, Z3 verticale ;
• une position escamotée, dans laquelle la portion 20 droite des montants 18 est sensiblement parallèle aux barreaux 19 (en traits discontinus sur la figure 2), c'est-à-dire sensiblement parallèle à la direction X2, X3 longitudinale.

Thus, each panel 2, 3 is deformable by rotation of the uprights 18 on the bars 19 and on the jaws 16, according to a deformable parallelogram formed on the one hand by the two uprights 18 and on the other hand by the bars 19 and the alignment of the jaws 16, between two positions:

• a raised position, in which the right portion of the uprights 18 is substantially perpendicular to the bars 19 (in solid lines on the figure 2 ), that is to say substantially parallel to the vertical direction Z2, Z3;
• a retracted position, in which the right portion of the uprights 18 is substantially parallel to the bars 19 (in broken lines on the figure 2 ), that is to say substantially parallel to the longitudinal direction X2, X3.

Due to the independence of the connection of the front panel 2 on the support arm 4 with respect to the connection of the rear panel 3 to the support arm 4, each of the two panels 2, 3 can be manipulated to be put in the position raised or in the retracted position without the position of the other panel being influenced.

Advantageously, the barrier 1 comprises means 22 for blocking each panel 2, 3 in the raised position. For this purpose for each panel 2, 3, one of the uprights 18 comprises a tongue 23 provided with an opening 24 and the corresponding jaw 16, that is to say the jaw 16 on which is mounted the amount 18 considered, comprises also an opening 25, for example threaded. When the panel 2, 3 is in the raised position, the two openings 24, 25 are in register, and an indexing finger 26 is inserted into the two openings 24, 25. The finger 26 may comprise a threaded portion cooperating with tapping the opening 24 on the jaw 16 to lock the finger 26.

It is now described the mounting of the barrier 1 according to the preferred embodiment on a bed 27, including a medical bed, with reference to Figures 3 to 6 .

The bed 27 comprises a lower frame 28, which can be mounted on wheels, and an upper frame 29 carrying a bed base 30 to define a surface 31 of coating. Means 32 for adjusting the height of the bed base 30 with respect to the lower frame 28, for example a crossbar system, can be interposed between the lower frame 28 and the upper frame 29.

The bed 27 has a region 33 of head, corresponding to the portion of the bed base 30 intended to support in particular the head and the torso of a patient, and a region 34 of feet, corresponding to the portion of the bed base 30 intended to support in particular the legs and feet of the patient. Means for raising the head portion of the bed base 30 relative to the foot portion, and vice versa, may be provided on the bed 27.

Bed 27 may also include a head panel and a foot panel 36.

The upper frame 29 includes in particular two longitudinal members 37 extending on each side of the bed 27 along its length, for example between the head panel 35 and the foot panel 36.

Barrier 1 is brought to the place of assembly in the folded position ( figure 3 ), so that the jaws 16 connected to the front panel 2 face a spar 37.

The jaws 16 of the front panel 2 are then placed on the beam 37, so as to be able to position the barrier 1 by sliding along the spar 37. It is then possible for example to put the panel 2 before abutting against the panel 35. head. The jaws 16 are then tightened by means of the handles 17, to block the front section 5 of the support arm 4 on the spar 37 (FIG. figure 4 ).

Thus, the jaw 16 carried by the front panel 2 which is not integral with the support arm 4 is the jaw placed closest to the head panel. Such an arrangement advantageously makes it possible, when the barrier 1 is assembled on the spar 37, to leave the spar portion 37 immediately adjacent to the panel 35. head, corresponding to the portion of spar that will line the patient's head lying on the bed. Other equipment necessary for patient care may then be placed near the patient's head and bust.

At this stage, the barrier 1 is already positioned on the spar 37 of the bed 27. The rear section 6 of the support arm 4 can, however, still pivot relative to the blocked front section 5 ( figure 5 ).

The barrier 1 is then placed in the extended position, so that the support arm 4 is substantially parallel to the spar 37 and that the jaws 16 of the rear panel 3 can be placed and then tightened on the spar 37 of the bed 27 ( figure 6 ).

The rotation of the sections 5, 6 of the support arm 4 relative to each other thus makes it possible to fix the jaws 16 two by two, instead of having to fix the four at the same time, so that the assembly is facilitated.

Alternatively, the jaws 16 may be integral with the spar, and the support arm 4 is attached to the jaws for locking. Means for indexing the jaws 16 on the support arm 4 may be provided for this purpose.

The barrier 1 thus assembled on the bed 27 can be dismounted easily, simply by loosening the jaws 16, then stored and stored in the folded position.

In addition, a fixed spacing between the two panels 2, 3 can be determined, given by the position of the links 12, 13, 14 of the front panel 2 and the rear panel 3 on the support arm 4, in order to meet the requirements of security. Thus, an operator assembling the barrier 1 on the bed 27 does not need to determine itself this distance, at the risk of going against the norms.

The retracted position of the panels 2, 3 makes it possible to fold them as close as possible to the spar 37, so as to release the sides of the sleeping surface 31 and facilitate both the access to the patient by the staff and the patient's exit from the patient. bed.

On the contrary, in the raised position, the panels 2, 3 extend above the spar 37, bordering the surface 31 of the coating, to prevent the patient from falling.

As indicated above, each panel 2, 3 is independent of the other. Indeed, it is for example possible to put the front panel 2 in the raised position and the rear panel 3 in the retracted position, for example to let the patient out of the bed 27 alone ( figure 7 ), the front panel 2 being available for the patient to use as support. The jaws 16 of the rear panel 3 may be loosened to put the barrier 1 in the folded position to achieve the same result. It is also possible to put the front panel 2 in the retracted position and the rear panel 3 in the raised position ( figure 8 ), for example to let the staff have access to the patient's head while ensuring the safety of the patient. It is however possible to put the two panels 2, 3 at the same time in the retracted position ( figure 9 ).

The position of the barrier 1 on the spar 37 is for example determined by the length of the support arm 4 in the deployed position. Indeed, the length of the beds can be standardized, so that for a given length of the support arm 4 in the deployed position, the abutment of the front panel 2 against the head panel 35 sets the other distances of the barrier 1 with respect to Bed panels 27 to meet safety requirements.

In the same way, a second barrier 1 can be assembled on the second spar 37 of the bed 27, so as to frame on either side the surface 31 of coating by the panels 2, 3 in the raised position.

The barrier 1 thus formed offers the advantages of half-barriers, while avoiding the disadvantages of assembly and disassembly.

Indeed, by providing a predetermined spacing between the panels 2, 3, an operator does not need to measure itself the position of the panels 2, 3 to meet the safety requirements and standards.

The barrier 1 can easily be mounted on the bed 27, in the manner of an accessory, that is to say without affecting the design of the bed 27. The bed 27 can then be manufactured in series, so as to reduce manufacturing costs, and barrier 1 only to be installed when needed.

In addition, in the folded position, the barrier 1 has a minimum size, so that it can be easily transported and stored.

The use of jaws 16 as fastening means allows a quick assembly, without tools, reducing the efforts of the operator.
