Mounting plate system, vacuum reservoir plate and electronic pump system for prosthetic socket and related methods

1. A method of providing a mounting plate system for use with a prosthetic socket, the socket having at least one aperture in a distal end thereof and in fluid communication with an interior portion of the socket which receives a residual limb, the method comprising the steps of:

arranging a mounting plate having a top face directly adjacent to a distal outer periphery of the socket, and a bottom face for attachment to lower portions of a prosthetic limb outside the distal outer periphery of the socket;

providing an opening in the mounting plate extending from the top face to the bottom face thereof;

providing a bottom recess in the mounting plate extending from the bottom face and surrounding the opening;

positioning a valve housing in the opening and having a channel therein for fluid communication with the interior portion of the socket via the at least one aperture, the valve housing having a shoulder portion arranged to abut the bottom recess in the mounting plate;

providing a dummy valve housing in the opening of the mounting plate and then bonding the top face of the mounting plate to the distal end of the socket to create a flat mating surface on the distal end of the socket for a flange of a one-way expulsion valve, the dummy valve housing including a drill guide therein;

laminating the mounting plate to the socket;

drilling a hole through the drill guide in the dummy valve housing to the interior portion of the socket to define the aperture;

removing the dummy valve housing;

positioning the one-way expulsion valve within the opening in the mounting plate; and

securing the one-way expulsion valve in place with the valve housing positioned in the opening of the mounting plate and compressing the flange thereof against the flat mating surface of the socket.

2. The method according to claim 1 , further comprising the step of:

securing a removable one-way expulsion valve directly between the valve housing and the socket adjacent the aperture and for regulating fluid communication between the interior portion of the socket and the channel in the valve housing.

3. The method according to claim 1 , wherein the bottom face of the mounting plate includes a pattern of threaded holes for attachment to lower portions of the prosthetic limb.

4. The method according to claim 1 , wherein the opening in the mounting plate comprises a threaded opening; and wherein the valve housing comprises a threaded portion for threaded engagement with the threaded opening in the mounting plate.

5. The method according to claim 1 , wherein the one-way expulsion valve comprises a rubber duckbill valve.

6. The method according to claim 5 , wherein the duckbill valve extends into the channel in the valve housing.

7. The method according to claim 1 , further comprising the step of:

providing a valve housing o-ring for sealing engagement between the valve housing and adjacent portions of the opening in the mounting plate.

8. A method of providing mounting plate system for use with a prosthetic socket, the socket having at least one aperture in a distal end thereof and in fluid communication with an interior portion of the socket which receives a residual limb, the method comprising:

arranging a mounting plate having a top face directly adjacent to a distal outer periphery of the socket, the mounting plate having a bottom face for attachment to lower portions of a prosthetic limb, and an opening extending from the top face to the bottom face of the mounting plate;

positioning a valve housing in the opening, the valve housing having a channel therein for fluid communication with the interior portion of the socket via the at least one aperture; and

removably securing a seal plate to the bottom face of the mounting plate;

removably securing a one-way expulsion valve directly between and against the valve housing and the socket distal outer periphery adjacent the aperture and for regulating fluid communication between the interior portion of the socket and the channel in the valve housing, wherein the one-way expulsion valve is positionable below the at least one aperture.

9. The method according to claim 8 , wherein the opening in the mounting plate comprises a threaded opening; and wherein the valve housing comprises a threaded portion for threaded engagement with the threaded opening in the mounting plate.

10. The method according to claim 8 , wherein the channel has at least first and second diameters formed along its length, the first diameter being greater than the second diameter and adapted to receive at least a portion of the one-way valve.

11. A method of providing mounting plate system for use with a prosthetic socket, the socket having at least one aperture in a distal end thereof and in fluid communication with an interior portion of the socket which receives a residual limb, the method comprising:

arranging a mounting plate having a top face directly adjacent to a distal outer periphery of the socket, the mounting plate having a bottom face for attachment to lower portions of a prosthetic limb, and an opening extending from the top face to the bottom face of the mounting plate;

positioning a valve housing in the opening, the valve housing having a channel therein for fluid communication with the interior portion of the socket via the at least one aperture; and

removably securing a seal plate to the bottom face of the mounting plate;

wherein the valve housing is arranged for compressing a flange of a one-way expulsion valve against the distal outer periphery of the socket to form a seal therewith.
