  • DVT deep vein thrombosis
  • venous thrombo-embolisms are conditions where clots form in the blood.
  • Patients undergoing surgery, under anesthesia, or undergoing extended periods of bed rest are at risk of clotting conditions associated with DVT.
  • the clotting conditions frequently occur in the deep veins of the lower extremities, such as in the lower legs, due to the tendency of blood to accumulate or pool in these areas. Static pools of blood can give rise to clotting conditions.

  • the connection tube of the inflatable bladder exits the inflatable bladder at a non-orthogonal angle relative to an edge of the inflatable bladder.
  • the leg engaging section defines at least one channel to permit the connection tube to exit the device. This diverting path traversed by the port and/or tubing works to reduce the risk of the patient developing a pressure ulcer.
  • the inflatable bladder is configured under a top material layer of the leg engaging section.
  • the inflatable bladder may be disposed along an optional ancillary cushioning layer. Either the compressible cushion layer or the optional ancillary cushioning layer can provide support to reduce the risk of a patient developing pressure ulcers when the inflatable bladder is deflated.

Abstract

L'invention concerne un dispositif (900) comprenant une section (101) adaptée à coopérer avec la jambe et une section (102) adaptée à coopérer avec le pied se croisant au niveau d'un dispositif (103) destiné à recevoir le talon. La section adaptée à coopérer avec la jambe et la section adaptée à coopérer avec le pied définissent une ouverture (104) d'insertion de jambe. Un premier élément d'enveloppement de compression (301) et un deuxième élément d'enveloppement de compression (302) s'étendent à partir de la section adaptée à coopérer avec la jambe. Une poche gonflable (501) peut être disposée le long de la section adaptée à coopérer avec la jambe, entre l'ouverture d'insertion de la jambe et une couche de coussin (902) compressible. La poche gonflable peut être gonflable sélectivement via un tube de raccordement (502) sortant de la poche gonflable sous un angle non orthogonal (504) par rapport à un bord (507) de la poche gonflable. La section adaptée à coopérer avec la jambe peut définir au moins un canal (1002) permettant au tube de raccordement de sortir du dispositif.
