DESCRIPTION

Bed comprising a barrier that includes a technical help point in the sitting position

The invention relates to the scope of medical beds, and more particularly to the scope of medical beds provided with barriers.

Medical care beds, or medical beds, can be found both in the home of individuals who need home help, as well as in specialized establishments, such as hospitals, clinics, or even residences.

A medical bed in general proposes different functionalities in order to relieve a patient. The functionalities thus depend on the pathologies of the patients to whom the bed is intended. They are nonetheless found in the majority of medical beds:

- small wheels that allow you to easily move the bed,

- a system that allows to adjust the height of the bed base to help the patient to settle in the bed and to get out of it,

- an articulated bed base that allows the patient's bust to be lifted, even to lift the feet equally,

- electric control means of the bed available to the patient,

- barriers that rise on each side of the bed base to prevent the patient from falling.

Patients who have reduced mobility often experience difficulty leaving the bed alone, and therefore need help. Now, it is always preferable, both for the physical form and for the morale of the patients, to offer them as much self-talk as possible.

Although the majority of the functionalities of the bed of medical character go in the sense of offering this autonomy to the patients, they can also hinder you.

Particularly, the barriers that rise on each side of the bed can prevent the patient from leaving it easily.

The barriers are often concealed, that is, they can take a raised position, in which they rise above the bed base, and a hidden position in which they are carried under the bed base, thus allowing the patient to get out of bed or the medical staff have easy access to the patient in bed and provide care.

There are different types of barriers, which can be grouped into three categories.

The first category includes the so-called simple barriers, which extend over the entire length of the bed. Document DE 20 2004 017 406 (BOCK) describes an example of such a barrier. The patient then has no means to get out of bed except to remove the barrier or put it in a hidden position.

The second category includes the three-quarter barriers, which extend over more than half the length of the bed. Such barriers generally extend from an edge of the headboard of the bed, without reaching the footboard, leaving then a free space by which the patient can get out of bed. However, in this case, the patient must move towards the edge of the footboard, which is not always possible.

EP 1,721,550 (HILL ROM) proposes a medical bed comprising a collapsible lateral barrier with deformable parallelogram mechanism and a removable accessory that extend between the lateral barrier in raised position and the transverse barrier of the bed. The function of this accessory is to fill the gap between the collapsible barrier, in the raised position and the transverse barrier of the bed, so as to avoid the patient's exit from this void and the risks of coffee. The accessory is said to be formed in a grab bar and is attached to the bed frame at the bottom end of two vertical free arms. Starting from one of its two vertical free arms, the accessory comprises a first horizontal part, a vertical part and a second horizontal part, so that the accessory is generally presented as a bent pipe in P. In a variant, a second Identical accessory to the first is fixed to the bed to allow a grip to the right and left of a patient sitting on the bed and trying to get up. The bed further comprises a D-shaped grab bar articulated to the concealed barrier, this grab bar having a substantially vertical section in raised position of the concealed barrier. A P-shaped accessory is also described in EP 801 915 (LE COUVIOUR).

The third category includes half barriers, that is, barriers that extend over at least half the length of the bed. In general, two half barriers are mounted on each side of the bed, in order to extend into the mayona of the bed extension and prevent the patient from falling from the bed base. The advantage of the half barriers is particularly that of allowing the removal, or hidden positioning, of a half barrier, and

leave the other one in its place, for example to allow the patient to get out of bed. Documents CA 2,454,931 (TEKNION CONCEPT) and EP 1,364,635 (VASSILLI) propose examples of such half barriers.

The above embodiments, if they offer possibilities for a patient to rely on barriers to get out of bed, still provide incomplete solutions.

Indeed, to get out of bed, it has been shown that it is easier for the patient to first sit in a sitting position on the edge of the bed, with the legs out of the bed.

The transition from the position thrown to the seated position of a patient with reduced mobility cannot be done without it being supported.

However, the above embodiments presented above do not allow the patient to easily grasp a part of the barrier. In fact, the patient naturally seeks to cling to the part of the barrier that is easier for him to access, without this part being adapted.

In addition, the patient should advantageously be attached to the barrier throughout the passage of the position thrown into the sitting position in which his legs are out of bed.

Now, when the patient can hold on to any part of the barrier, he may have to move his hand over the barrier in the course of his movement between the cast position and the sitting position, in order to always grab a part of the barrier and reach the exit, which can make the movement more annoying.

Thus, the three-quarter barrier requires the patient to get up to the bed footrest to get out of the bed, moving his hand along the barrier, which is annoying, even impossible for some patients.

EP 2,275,068 (HILL ROM) proposes to form in a three-quarter barrier a handle approximately half the length of the barrier, so that the barrier extends to either side of the handle. The barrier is not concealed and is integral with the part of the bed base that supports the bust, which can be lifted.

Other examples of medical-type bed barriers provided with grip areas can be found in WO 2007/010227 (HUNTLEIGH), WO 03/053322 (HILL ROM), US 2003/0056293 (BROKE), EP 780 075 (LE COUVIOUR).

Numerous realizations of grab bars or technical help points placed on the sides of the bed are known on the other hand. A "technical help point" refers to a point designed and located to help patients to change their position in bed on this point. Reference may be made, for example, to documents US 2006/0130239, US 5,394,581, EP 0.626,163. The support handles added to the sides of the bed are conventionally formed barriers formed by horizontal and vertical tubes welded together, with a height of 25 or 40 cm and a variable width, for example 30, 50 or 80 cm.

A first object of the invention is to propose a bed, particularly a bed of a medical nature, comprising a barrier that allows the patient lying in the bed to easily grasp it to get out of it.

Another object of the invention is to propose a bed, particularly a medical bed that comprises a barrier that facilitates the exit of the patient's bed.

Another object of the invention is to propose a bed, particularly a medical bed, comprising a barrier that limits the obstacles to the patient's exit, preventing the patient's coffees lying in bed.

Another object of the invention is to propose a bed, particularly a bed of a medical nature, comprising a barrier, particularly adapted to persons of legal age.

Another object of the invention is to propose a bed, particularly a medical bed, comprising a barrier whose manufacturing costs are limited.

For these purposes, the invention according to claim 1, refers to a bed, in particular a bed of a medical nature, comprising a lying plane limited by a longitudinal edge and two transverse edges, called headboard and footboard, the bed also comprising a headboard barrier located along the longitudinal edge, the barrier comprising a front end and a rear end, the front end being closer to the head edge than the rear end, the bed comprising a frame on which a lying surface, the headboard barrier being articulated to the frame and being conceivable, the headboard barrier comprising a first substantially square handle for lifting the

- the foot barrier is articulated to the frame and is concealed;

- the bed comprises a lying surface, the lying surface comprising an articulated headboard part in relation to the frame between two positions, a lying position in which the headboard portion is substantially horizontal and a sitting position, in which the part headboard forms an angle relative to the horizontal, the joint being at a distance relative to the edge of the headboard, measured along the longitudinal edges, between 60 cm and 80 cm;

- the bed comprises a second support handle to turn the patient around, this second handle being integral with the headboard barrier;

- the second handle is mounted articulated to the headboard barrier.

Other objects and advantages of the invention will appear in the light of the description of a preferred embodiment, given below in reference to the attached drawings in which:

- Figure 1 is a perspective view of a bed, a patient lying on the bed holding a first handle located on a side barrier;

- Figure 2 is a view analogous to Figure 1, the patient having moved to the position sitting on the bed;

- Figure 3 is a detail side view of the bed represented in Figures 1 and 2, the concealed barrier being represented with broken lines in an unfolded position and in continuous lines in a retracted position;

- Figure 4 is a perspective view of the bed represented in Figures 1 to 3, a patient lying on the bed and holding onto a second handle located in the half headboard barrier of the bed.

In figure 1 a bed 1 of a medical character is shown on small wheels 2. The bed 1 comprises a chassis comprising a lower frame 3, an upper frame 4 that overhangs the lower frame, and a device 5 for regulating the height of the upper frame 4.

The lower frame 3 comprises stringers and crossbars, the small wheels 2 being arranged substantially at the four angles of the lower frame.

The upper frame 4 comprises a frame in which a lying surface is fixed. The lying surface may comprise two articulated parts, namely a part for a user's legs and a part for the bust.

The upper frame 4 may comprise equipment for a user such as a davit, or also a headboard and a footboard (not shown).

The regulating device 5 comprises two crossbars 5a, 5b and a crossbar drive system, for example an electric jack.

The bed 1 comprises, at least on one of its major lateral sides, two concealed barriers: a first concealed headboard barrier 6 and a second concealed footrest barrier 7.

Advantageously, the bed 1 comprises in each of its two longitudinal edges a concealed headboard barrier 6 and a concealed footrest barrier 7.

The first barrier 6 can be hidden between a raised or deployed position, represented in figures 1, 2 and 3, and a collapsed or hidden position, represented in figures 3 and 4.

The first barrier 6 is mounted in an articulated manner in relation to the upper frame 4 and is formed by tubular elements articulated between them

The headboard barrier 6 comprises a first tubular element 8 articulated to the upper frame 4 around a transverse axis 9 and a second tubular element 10 articulated to the upper frame 4 around a transverse axis 11.

The headboard barrier 6 also includes tubular connecting elements 12, 13, 14, each articulated, on the one hand in relation to the first tubular element 8 about a respective transverse axis 15, 16, 17, on the other hand in relation to the second tubular element 10 about a respective transverse axis 18, 19, 20.

In the raised position of the headboard barrier 6, the first tubular element 8 is substantially vertical and the tubular connecting elements 12, 13, 14 are substantially horizontal. A first tubular joint element 12 forms the upper edge of the headboard barrier 6 and extends, by way of indication, at a height of 35 cm above the bed base.

The second tubular element 10 comprises in the upper part a first handle 21.

The first handle 21 advantageously has a different color from that of the first barrier assembly 6. For example, the first handle 21 will be blue, the rest of the first barrier 6 having a typical gray color of a metal part, for example aluminum . The user of the bed 1 thus sees his gaze attracted by the handle 21, of a color different from the rest of the headboard barrier 6 and different from the usual target of the hospital environment. In one embodiment, the first handle 21 is coated with a phosphorescent material. Advantageously, the first handle 21 has a non-slip surface. For example, the first handle 21 is coated with an elastomer or is provided with ribs or reliefs. The user of the bed 1 thus has his touch attracted by this part of the barrier 6 of the headboard.

The first handle 21 is generally annular in shape of substantially square contour that allows it to be gripped in at least six different ways: one-handed grip by one of the four sides of the first handle 21, or two-handed grip of the first handle 21.

Advantageously, the first handle 21 is located at a height of approximately 25 to 50 cm in relation to the bed base and one third of the length of the bed 1. This arrangement allows the person lying in bed 1 on the back or on the side to grab No major bust displacement:

- with the right hand, knob turned upwards, a first handle 21 located to its right (that is to the left of the bed 1 from the point of view of an observer located at the foot of the bed 1), as has been illustrated with broken lines in figure 1, or

- with the left hand, likewise turned upwards, a first handle 21 located to its left (that is to the right of the bed 1 from the point of view of an observer located at the foot of the bed 1).

This provision provides a convenience of use, in particular for persons of legal age or suffering from joint problems.

The first handle comprises, in the embodiment shown, four tubular portions that preferably form a trapezoidal contour, namely: a lower tubular portion 21a, an upper portion 21b and two lateral portions 21c, 21d. The lower portion 21a forms an angle A of approximately 30 ° with the horizontal in the raised position of the headboard barrier 6, while the upper portion 21b forms an angle B of approximately 30 ° relative to the lower portion 21a (and therefore of approximately 60o in relation to the horizontal), these values being indicative.

In the lowered or hidden position, the headboard barrier 6 extends below the upper plane of a mattress 40 and above the lower frame 3, thus the first barrier 6 does not constitute any discomfort to the movements of the patient or persons located around the bed 1. Stop stops ensure the end of pivoting travel of the headboard barrier 6 in its hidden position.

A mode of use of the first handle 21 in the raised position of the first barrier 6 will be described below.

In a first phase, the patient will grasp with his right hand the first handle 21 located on his right (that is to the left of the bed 1), for example the lower portion 21a. The position of the first handle 21 (height in relation to the bed base, located in the third of the length of the bed) as well as the angle of approximately 30o formed by the lower portion 21a or the upper portion 21b of the handle 21 limits the movements of the shoulder of the patient, and these movements of the patient's shoulder may be difficult or painful for the elderly. The patient only has, on the other hand, advantageously that to lift the arm or elbow to grip the first handle 21. The barrier of the footrest 7 has been previously hidden. Advantageously, during this grip of the lower portion 21a of the handle 21, the patient's hand is oriented with the knob turned upwards. If necessary, as shown in Figure 1, the patient can grasp the handle 6 with both hands, taking the upper portion 21b with his left hand. This provision provides a convenience of use, in particular for persons of legal age or suffering from joint problems.

In a second phase, the patient, keeping his grip of the first handle 21, in particular of the lower portion 21a of the handle 21, will begin to run his legs along the side of the bed.

In a third phase, the patient is sitting on the bed 1 and is always held with one or two hands to the first handle 21, as illustrated with broken lines in Figure 2.

In a fourth phase, the patient can get up. It should be noted that no barrier element is located directly behind the patient's knees or calves, which allows him to place his feet in the vertical of his center of gravity without having to exert a traction with his arms.

In order to complete the bed ergonoirna, the first handle 21 is preferably located at a longitudinal distance from the edge of the headboard of the bed between 50 cm and 75 cm, that is to say that it is level or under the elbow of the mayona of the patients.

A second handle 22 is mounted in an articulated manner in relation to the first tubular element 8 of the first barrier 6. As can be seen in Figure 3, when the first barrier 6 is in a hidden position, this second handle 22 extends substantially near the upper plane of the mattress 40 and can help the patient in their movements, particularly in their repositioning or tilting on the side, for example during care. In this regard, the handle 22 is positioned longitudinally in relation to the bed 1 at a distance between 25 cm and 60 cm from a headboard edge 1, which corresponds to the shoulder of a medium-sized patient lying in the bed one.

The second handle 22 advantageously has a different color from that of the headboard barrier assembly 6. For example, the second handle 22 will be blue, the rest of the first barrier 6 having a typical gray color of a metal part, for example aluminum. The user of the bed 1 thus sees his gaze attracted by the handle 22, of a color different from that of the rest of the barrier 6 and different from that of the usual target of the hospital environment.

In one use, the second handle 22 is coated with a phosphorescent material. Advantageously, the second handle 22 has a non-slip surface. For example, the second handle is covered with an elastomer or is provided with ribs or reliefs. The user of the bed thus has his touch attracted by this part of the first barrier.

The second handle 22 is advantageously concealable, being articulated in relation to the tubular element 8, around an axis confused with this element 8 or, as illustrated in the figures, parallel to it. Thus, in the exemplary embodiment illustrated, the handle 22 is articulatedly mounted on each of its ends around a pivot at the end of a finger 22a integral with the tubular element 8.

In its collapsed position, illustrated in Figures 1 to 3 and with broken lines in Figure 4, the second handle 22 does not hinder the movements of the patient at his exit from the bed or his entry into it. In its raised position, illustrated with continuous lines in Figure 4, the second handle 22 ensures an assistive function to turn the patient around.

The second handle 22 preferably has a curved shape, in the form of a circle arc or ellipse arc and thus comprises a section substantially horizontal and parallel to the bed base, when the second handle 22 is in the raised position.

This second handle 22 can be used when the headboard barrier 6 is in the lowered position, as illustrated in Figure 4, where a patient tilting on the side is necessary. Rather than helping the patient to carry out this movement, the caregiver tilts the handle from its collapsed position to its raised position, as indicated by the arrow in Figure 4.

The headboard barrier 6 being in its collapsed position, the tubular element 8 around which the handle 22 is articulated extends substantially horizontally, or slightly obliquely, below the upper surface of the mattress 40. In its raised position, the handle forms at least partly protruding above the mattress 40, so that it is sufficient for the patient to grip the handle 22 with the opposite hand next to the bed where the handle 22 is located, and pull with its arm to swing on the side, as indicated by the arrow in figure 4. In order to allow the patient to grip the handle 22, it may be provided with a stop system that locks it in the raised position. This system works for example by crimping, or also by friction. In a variant, it is the caretaker who holds the handle 22 in the raised position.

The handle 22 allows not only to be placed, but also to stay on its side when lying on the bed 1, in a position called half-turn facilitating some care or avoiding necrosis. Access to this second handle 22 favors autonomy and reeducation, reducing the efforts of the personnel who take care of the patient's mobilization.

The locking means in displaced and hidden position of the first barrier 6 are advantageously placed

at the height of the caregiver's job, he only has to lean or extend his arms to operate them. These locking means are for example friction latches, known per se.

The second barrier 7 can be hidden between a raised or deployed position, represented in Figure 4 and a collapsed or hidden position, represented in Figures 1 and 2.

The second barrier 7 is assembled to form articulated in relation to the upper frame 4 and is formed by tubular elements articulated between st The second barrier 7 comprises a first tubular element 23 articulated to the upper frame 4 around a transverse axis 24 and a second tubular element 25 articulated to the upper frame 4 around a transverse axis 26.

The second barrier 7 also includes tubular connecting elements 27, 28, 29 each of these joining elements being articulated, on the one hand in relation to the first tubular element 23 about a transverse axis 30, 31, 32, on the other hand with relation to the second tubular element 25 about a transverse axis 33, 34, 35.

In the raised position of the second barrier 7, the first tubular element 23 is substantially vertical and the tubular connecting elements 27, 28, 29 are substantially horizontal. A first tubular joint member 29 forms the upper edge of the footrest barrier 7 and extends, by way of indication, at a height of 35 cm above the bed base.

In the lowered or concealed position, the footrest barrier 7 extends below the upper plane of the mattress 40 and above the lower frame 3, thus forming the barrier 7 no discomfort for the movements of the patient or of the persons around the bed 1. Stop stops ensure the end of the pivoting path of the second barrier 7 in its hidden position.

The locking means in the unfolded and hidden position of the footrest barrier 7 are advantageously positioned at the caregiver's working height, which only has to be inclined or to extend the arms to actuate them. These locking means are for example friction latches, known per se.

In one embodiment, the barriers 6 and 7 have an essentially identical structure, with the exception of the handles 21, 22 added to the first barrier 6. The elements of the bed 1 are made for example in metal, such as aluminum, or in alloy, for example stainless steel. Decorative wooden sheets can be removably attached to stringers and crossbars.
