Pressure ulcer prosthesis and method for treating and/or preventing pressure ulcers
A pressure ulcer prosthesis ( 10 ) having an elongated body ( 11 ) to support a patient's limb. The body ( 11 ) has a longitudinally extending support surface ( 13 ) that is arcuate and concave in transverse cross section. A distal end ( 12 ) having a surface ( 18 ) extends away from the surface ( 13 ) so as to diverge therefrom so that a portion of the limb adjacently surface ( 18 ) is released from pressure.
1. A pressure ulcer prosthesis comprising an elongate body to support a patient's lower limb, said body having:
(a) a longitudinal axis and a longitudinally extending support surface which, in use, receives an underside of the lower limb, said support surface in transverse cross section being arcuate and concave;
(b) a distal end with a further surface extending from the support surface so as to diverge from the longitudinal axis such that a portion of the lower limb adjacent the further surface is relieved from pressure; and
(c) means for substantially preventing the patient's lower limb from hyperextending, when the prosthesis is being worn by the patient while the patient is supine on a surface, by raising a proximal end of the elongate body relative to the distal end.
2. The prosthesis of claim 1 , wherein the means for substantially preventing the patient's knee from hyper extending when the prosthesis is being worn by the patient while the patient is supine on a surface follows a contour of the outer surface of the prosthesis body.
3. The prosthesis of claim 2 , further including means for securing the pressure ulcer prosthesis to the lower limb with the distal end above a bottom portion of the patient's foot such that the prosthesis does not interfere with the patient's walking.
4. The pressure ulcer prosthesis of claim 2 , wherein, in use, the prosthesis does not make contact with the sole of the patient's foot.
5. The prosthesis of claim 1 , further including means for securing the pressure ulcer prosthesis to the lower limb with the distal end above a bottom portion of the patient's foot such that the prosthesis does not interfere with the patient's walking.
6. The pressure ulcer prosthesis of claim 1 , wherein the means is on an outer surface of the prosthesis body proximal a proximal end of the prosthesis.
7. The pressure ulcer prosthesis of claim 1 , wherein, in use, the prosthesis does not make contact with the sole of the patient's foot.
8. The pressure ulcer prosthesis of claim 1 , wherein the means for substantially preventing the patient's lower limb from hyperextending is a block.
9. The pressure ulcer prosthesis of claim 8 , wherein the block is of a rectangular shape.
