DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device intended to allow lower limbs to be positioned, as desired, for persons having to remain in a supine position for a more or less extended period.
The present invention responds to several objects:
In the first place, it will enable persons having to remain lying down, whether it be question of persons immobilized momentarily further to functional disorders or even of bed-ridden persons.
It is known that such persons who remain lying on their back for long periods of time are subject to bed-sores, particularly on those parts of the body which remain in permanent contact with the rest surface; material means have been developed in order to overcome the formation of bed-sores, particularly in the form of air beds comprising internal cells which are alternately placed under pressure, so as to alternate the parts of the body which are in position of support; however, this method is inefficient in the case of the formation of bed-sores on the heels, being given the very punctual and permanent character of the rest position occupied by this part of the body, the patient lying on his back.
It is therefore a first object of the invention to allow the patient to remain in supine position for an extended period of time, whilst avoiding the formation of bed-sores on the heels, on the one hand, or to reduce the duration of cure of the existing bed-sore.
Another object of the invention aims at making it possible to ensure a precise positioning of the lower limbs under specific circumstances requiring, at least during an intermediate period of time, that the lower limbs of a patient in supine position be maintained stable at a determined angle.
Such is the case in particular of patients having undergone an operation resulting in a prosthesis being positioned at hip level; whenever patients have undergone a hip operation by total or partial arthroplasty, it is desirable, in order to avoid a post-operatory dislocation, to ensure positioning and maintenance of the lower limbs at a precise angle.
The invention responds to this end and furthermore makes it possible to avoid muscular tensions of the retentor muscles in the buttocks, and finally to maintain in suitable position osteotomies and bone grafts of the hip or pelvis; for example MacMurray or Chiari osteotomy.
A third object of the invention will be to ensure, by a centripetal inclined position of the lower limbs, an improved venous circulation, avoiding, furthermore, risks of oedema of the lower limbs.
Finally, and according to a more general object of the invention, the latter will be applicable to all circumstances in which it is desirable to ensure a comfortable rest of the lower limbs of a bed-ridden patient and more especially whenever the patient will have suffered traumatisms at that level, for example in the case of patients having multiple injuries of the lower limbs, patients having undergone a punctual surgical operation on the thigh, knee, leg and ankle, including continuous tractions, etc. . .
To that end, the invention relates to a device for giving a set position to the lower limbs of persons required to remain in a supine position for an extended period, said device being characterized in that it comprises at least one block offering two side support surfaces for the legs, the vertical planes of the two surfaces converging at a determined angle corresponding to the desired positioning of the two lower limbs.
More especially, the block is preferably constituted by a hexahedral structure, comprising two horizontal parallel surfaces of trapezoidal shape, respectively upper and lower, connected together by the two side support surfaces converging towards the patient.
It will be understood that these two surfaces for supporting the limbs thus define the appropriate angle, the patient being required to maintain his two legs against its two faces diverging towards the feet, thus constituting a correct angular point of reference for positioning the legs.
The block is preferably made of elastically compressible, semi-ri
