Description

The present invention relates to the field of means assistants to help with the movement and / or the change of posture for persons with disabilities and has as its object a device for the change of posture and / or the transport of such a person, in particular for the care of home.

Mobility aid for permanent disabled persons or temporary workers having difficulty changing position and moving generally using specific devices at each need, such as lifting gantry means to lift and to transfer said persons from one medium to another or to a device specific and transfer means of the wheelchair type.

Gantry lifting means, also called patient lifts, generally comprise a frame mounted on rollers and a lifting arm provided with an attachment device for straps of a transfer seat. These known lifting means have led to the care establishments adaptations of care or rest facilities, such as beds, baths and the like, in order to allow, when maneuvering said means lifting with patients, a displacement of the lower part of the frame equipped with rollers under said facilities.

Such a means is in particular known from DE-U-202 19 389 and is specially adapted to healthcare establishments, so that domestic is possible only at the cost of costly adaptations. In Moreover, the implementation of these means generally requires proven professional skills and their storage after use requires a lot of space. It follows that the use of the means of Known maneuvering is very limited in the field of home care.

In addition, these known means generally solicit the spine of nursing staff in the sense of a load, leading to a long-term health problem for the said staff, particular of back pain. By the way, it's laying for patients a bed-keeping problem, which leads to a disruption of rhythms biological, so that there can be confusion between day and night, the patient sleeping during the day and no longer sleeping at night.

Caregivers may be tempted, for this purpose, to intervene by prescription of drugs facilitating nocturnal sleep, with, however, the consequence of this is the risk of side effects. In fact, it is important to keep the patient out of bed while sitting to read, to eat or to see TV shows or even standing or walking, to perform exercises intended for promote mineralization of the skeleton, as well as to prevent atrophy muscular.

The present invention aims to overcome these disadvantages by proposing a device for the change of posture and / or transport disabled person, in particular for home care, allowing easy and simple use and storage in a volume restricted.

For this purpose, the device for the change of posture and / or the transport of a disabled person, in particular for home care, is characterized in that it is essentially constituted by a rolling chassis of vertical support and tipping and by a support assembly horizontal position which can be folded over the vertical support rolling frame, position of non-use of the device.

In addition, the seat 9 is advantageously provided in its edge rear of a recess 9 "'intended to allow access to a bowl of Toilet.

The postural change maneuvering means 10 is pivotably mounted on the frame 8, on the opposite side to the seat 9 and preferentially in the form of a U-shaped frame articulated on the corresponding end of the frame 8 via an axis 10 'and can be maintained in the service position with respect to this frame 8 at means of knurled thumbscrew 16. Because of this assembly to articulation of the means 10 on the frame 8, the latter can be folded over the frame 8 in the position of non-use of the device according to the invention, as shown in Figure 12 of the accompanying drawings.

According to an alternative embodiment of the invention, not shown in the accompanying drawings, the posture change maneuvering means 10 can also be mounted on the frame 8 via provided at the end of his arms and cooperating with devices corresponding to frame 8, maintaining the service position of the 10 relative to the frame 8 being provided by means of clamping screws to knurled head, or the like. It is also possible to make the connection between the posture change maneuvering means 10 and the frame 8 by simple bolting or screwing of the ends of the means 10 on the frame 8.

The retractable backrest 11 is advantageously constituted in two identical elements, symmetrical with respect to a median plane to the device and each connected to a lever 11 'pivotally articulated vertically around a axis provided on one side of the end of the frame 8 opposite the means 10 of posture change maneuver, said vertical pivoting being limited, for each lever, in the service position and in the release position rotated, via stops provided on the pivot axis and / or by means of a latch device connecting the free ends of the elements in the service position. Such a pivoting means, the stops and the lock device are of known type and do not require description complementary.

According to another characteristic of the invention, the frame 8 of the patient support assembly B, articulated on the support frame Vertical 1 of the vertical support and tilting chassis A, is provided, in addition, retractable supports 17 in the form of articulated feet to the end of said frame 8, near the articulation of the eclipsable folders 11, these supports 17 each cooperating with a rod 18 articulated to a end on the support 17 and having at its other end a guided ergot in a slider 19 extending along the lower part of the frame 8, this pin can be locked in the service position or in the position of folding the supports 17 along the frame 8 via a device cam-type locking device 20 making a stop in the lock position by deformation of its guidance. Such deformation can in particular be provided by prediction, within the slide guide of an element deformable under the action of a cam or the like. In addition, the blocking 20 is perfectly manoeuvrable by a person in front of the posture change maneuvering means 10.

Finally, the device according to the invention can also be equipped, between the vertical support frame 1 with the sleeve 7 for the axis 8 'of pivoting of the frame 8 and the axis 10 'of pivoting means 10 maneuvering of posture change, of a platform 21 forming simultaneously table and rest element for the forearms.

According to another embodiment of the invention and as shown in Figures 10 and 11 of the accompanying drawings, the support frame vertical 1 may be provided with a complementary anti-tilt means rear 22 consisting essentially of two levers 22 'fixed on said frame 1 at one of their extremities and fixed at their other end to a 22 "crossbar ground support. Thus, it is possible during relatively long journeys of raise the retractable supports 17 against the frame 8 and ensure the stability against an accidental tilting via means 22. This medium 22 can also ensure a transfer to a supine position, the crossbar 22 "serving as support points to perform the rotation of the device.

In the position of non-use of the device according to the invention, it is in a folded form around the frame vertical support and tipping device A, as it appears on the Figure 12 of the accompanying drawings. For the implementation of the device, the horizontal support assembly B is unfolded by pivoting the frame 8 around its axis 8 ', after having previously dismantled the headrest 5 of the vertical support frame 1. Then the retractable supports 17 are brought into their position shown in Figure 1 by unlocking the equipping pin each link 18 by means of the locking device 20.

Next, the posture change maneuvering means 10 is rotated about the axis 10 ', also in the position shown in FIG. Figure 1 of the accompanying drawings and is locked in this position by means of knurled thumbscrew 16, the eyelets 9 'on one side of the seat 9 are unhooked from the corresponding attachment means 9 "and the elements of the retractable backrest 11 are pivoted in a vertical position clearing the rear part of the frame 8. Thus, the device complies with the invention is ready to be implemented for the care of a patient.

For this purpose, for example, if a patient is sitting on the edge of a bed (FIG. 2), the device is approached to said patient in such a way that can be completely surrounded by the arms of the frame 8, the supports retractable 17 being raised along said arms of the frame 8.

On arrival in this position, the patient is installed in the device, after prior locking of the wheels 2, so as to avoid any the latter, by positioning his feet on the axle of the wheels 2 and support of his legs against the support device 4. During these maneuvers, the patient is moved on the edge of the bed, so that the seat 9 can be passed under her thighs and that these 9 'eyelets can be hung in the attachment means 9 "In this position, the patient is already maintained on the device and it is enough to put back the file eclipsable in its service position against the patient's lumbar by rotation of the levers 11 '.

The patient can then be lifted from his support on the bed by pivoting of the device on the anti-tilt stop 3, after pressing on the 10 means of posture change maneuver. It follows a release of the patient from the bed and, for safety, the retractable supports 17 are advantageously put in the service position (FIG. allow the device to be returned to normal position, such as shown in Figure 3 of the accompanying drawings.

Figure 4 shows the device in a position in which the patient is held in a sitting position, for example to take a meal.

To bring a patient to a horizontal position, such as shown in FIG. 6 of the accompanying drawings, it is firstly a partial folding of the retractable supports 17 promoting a tilting towards the rear of the device, as shown in FIG. 7 of the drawings. attached. In this position, the elements of the backrest 11 are pivoted towards the top so as to clear the space in the back of the patient and then said device can be tilted into the position shown in Figure 6 appended drawings, after stalling the seat 9.

To perform standing exercises and ambulation, the patient can either, as shown in Figure 8, perform his exercises by simply standing in front of the seat 9 that remains maintained by its eyelets 9 'on the frame 8, so without any modification the device, or, as shown in Figure 9, perform its exercises in leaning on the back of frame 8 and standing and / or walking behind the latter, the retractable supports 17 then forming an element of safety against too much tilting of the device. In the first case, when the patient is inside the frame 8, total safety is ensured by all the constituent elements of the device and in case of fatigue, the patient can very quickly end up in a sitting position, such as shown in Figure 3.

Finally, in the forward tilting position shown in FIG. 5, it is possible, by supporting the device on the anti-tilt stop before 3 and on the front end of the means 10 to lavish at patient specific care of the lower back and especially to the anal area, especially after going to the bathroom.

Thanks to the invention, it is possible to produce a device for the change of posture and / or the transport of a handicapped person allowing the patient to be well-supported against the risk of falls during his periods of stay out of bed and this by ensuring a large number of Possibilities of positions.

In addition, this device allows a return of the solidification of the spine and relaxation of the spine, so that the caregiver can perform the rollover function. this is particularly interesting to perform, for example, a transfer of a patient in a bathtub from a bed and conversely, while promoting the clearance from the edge of the bath or bed.

As a result, the working conditions of the staff Caregivers are very much improved, especially in the context of Home Care. In such a case, the persons performing the care are not always professionals and they themselves incur risks that can affect their skeleton, due to false maneuvers. The device according to the invention makes it possible to reduce these risks, even to suppress them, because it leads to the skeleton of the caregiver a discharge effect of the spine, due to the maneuver by the means 10 to take advantage of the weight of the patient.

Finally, the device according to the invention allows patients having some mobility to practice holding exercises standing and walking under surveillance and so some form of Rehabilitation, while being perfectly insured against any risk of falling accidental.

Of course, the invention is not limited to the mode of embodiment described and shown in the accompanying drawings. Modifications remain possible, particularly from the point of view of the constitution of the various elements or by substituting technical equivalents, without going out for as much of the field of protection of the invention.
