Definitions
- the invention relates to apparatus for dorsiflexion of a user's foot and a method therefor.
- Foot dorsiflexion supports venous blood flow return in a subject's lower limbs and is particularly useful for prevention of venous thrombosis.
- Apparatus for effecting foot dorsiflexion has been proposed for able bodied subjects in US Patent
- apparatus for dorsiflexion of a seated user's foot comprising a rigid base with heel restraining means and foot restraining means for restraining the user's foot on said base; forefoot elevation means underlying the foot's front portion alternately disposable between a first state whereby the foot's front portion lies adjacent to said base and a second state whereby the foot's front portion is elevated relative to said base thereby effecting its dorsiflexion.
- the apparatus of the present invention is particularly suitable for use as an accessory to wheelchairs, the apparatus being provided as a stand alone unit thereby facilitating dorsiflexion of a wheelchair bound user's feet in a convenient and comfortable manner whilst not impairing his mobility to perform everyday activities.
- a method for dorsiflexion of a seated user's foot comprising the steps of:
- Fig. 1 is a pictorial view of apparatus for dorsiflexion in a seated user's foot in accordance with the present inevntion;
- Fig. 2 is a perspective view of the inflatable member of the apparatus of Figure 1;
- Figs. 3A and 3B are side views of the apparatus of Figure 1 during operation; and
- Fig. 4 is a pictorial view of a wheelchair fitted with the apparatus of Figure 1.
- apparatus 1 for dorsiflexion of a seated user's foot includes a rigid platform 2 with a heel support 3 and a foot strap 4, and an inflatable member 6.
- the inflatable member 6 is connected to a compressor 7 under the control of a controller 8 controlling the inflatable member's maximum degree of inflation and its cyclic rate of inflation and deflation.
- the inflatable member 6 assumes a generally flat configuration (dashed lines) when deflated and a generally wedge-shaped configuration (solid lines) having its leading edge 6A directed toward the heel support 3 when inflated, the latter configuration adapted for raising the front portion of a user's foot relative to the platform 2 for its dorsiflexion.
- the inflatable member 6 includes a three sectioned cover 9 having sections 9A, 9B and 9C, the sections 9A and 9B being formed as a pouch 11.
- the pouch 11 contains a generally square single inflatable cell 12 divided into two equal sized compartments 12A and 12B by two seams 13A and 13B lateral of a central portion 14 enabling flow communication between the two compartments 12A and 12B.
- Each compartment 12A and 12B has a rigid member 16 disposed therein and one of the compartments 12A and 12B is provided with an inlet port 18 which also serves to inflate the other compartment.
- the cover 9 is formed into a closed generally equilateral shape whereby the section 9B is adjacent the platform 2 whereby the section 9C acts as a restraining member for limiting the maximum height of the inflatable member 6 when fully inflated.
- the inflatable member 6 requires a relatively small volume of compressed air to assume its wedge-shaped configuration thereby facilitating a relatively rapid cyclic rate of inflation and deflation.
- a user's foot is placed on the platform 2 and strapped in using the foot strap 4.
- the user sets the controller 8 to his preferred settings for maximum inflation height of the inflatable member 6 and cyclic rate of inflation and deflation.
- the maximum inflation height is about 7 cm from the platform 2 whereby the user's foot subtends an angle of about 20 degrees relative thereto.
- the cyclic rate of inflation and deflation can be set between 1 to 3 cycles per minute.
- the inflatable member is cyclically inflated and deflated by intermittent operation of the compressor 7, deflation being assisted by the natural downward tendency of a person's foot.
- a wheelchair 19 having left and right foot supports 21 A and 21B is provided with a system 22 for effecting dorsiflexion of wheelchair bound user's both feet, the system 22 including a rechargeable battery operated compressor 23, a controller 24 and two apparatus 26A and 26B for his left and right feet, respectively.
- the compressor 23 and the controller 24 are carried on a rack 27 and the apparatus 26A and 26B are respectively mounted on the wheelchair's foot supports 21 A and 2 IB whereby the system 22 is fully portable and therefore does not preclude the user from continuing with his everyday activities.
- the forefoot elevation member can be implemented by other mechanical or hydraulic devices, for example, a motorized eccentrically mounted wheel, and the like.
- the apparatus is primarily designed for use by users wearing shoes whereupon the inflatable member can be disposed underneath a user's metatarsals and/or toes. Alternatively, the apparatus can be used by barefooted users whereby the inflatable member is disposed underneath a user's metatarsals.

Abstract
L'invention concerne un appareil (1) permettant la dorsiflexion du pied d'un utilisateur assis. Ledit appareil (1) comprend une base rigide (2) dotée d'un moyen de retenue du talon (3) et d'un moyen de retenue du pied (4) permettant de retenir le pied de l'utilisateur sur la base (2); un dispositif de surélévation (6) de l'avant-pied, se trouvant au-dessous de la partie avant du pied et se plaçant en alternance dans une première position dans laquelle la partie avant est adjacente à la base (2) et dans une deuxième position dans laquelle la partie avant du pied est surélevée par rapport à la base (2), ce qui permet le mouvement de dorsiflexion.
