Easy on/easy off clips or clamps for mounting mask to body part fixation device

A structure, comprising:

• a first frame having a shape to fit around, or over, a body part, the first frame further comprising a first surface configured to dock with a docking surface of a second frame configured to receive and support the body part;
• a material attached to the first frame for fitting to the body part;
• and
• at least one attachment mechanism coupled to the first frame and configured to attach the first frame to the second frame when the first surface of the first frame is docked with the docking surface of the second frame, wherein the at least one attachment mechanism is configured to flex or pivot, relative to a lateral edge of the first frame, to attach the first frame to the second frame when the first surface of the first frame is docked with the docking surface of the second frame.

A medical treatment mask, comprising:

• a mask frame comprising:
• a first shape that fits around or over a patient's body part, and
• at least one clip or clamp connected to the mask frame and configured to clip or clamp the mask frame to a body part positioning device when the mask frame is docked with the body part positioning device,
• wherein the at least one clip comprises at least one flexible spring arm connected to an outer edge of the mask frame and wherein the at least one flexible spring arm flexes in an outward direction from the outer edge of the mask frame to enable a mounting retention member to clip to or unclip from a surface of the body part positioning device, and
• wherein the at least one clamp comprises at least one clamping arm configured to rotate about a rotation axis upon the mask frame and clamp the mask frame to the body part positioning device;
• and
• a sheet of material attached to the mask frame for fitting to the body part.

A structure for positioning a body part, comprising:

• a support base;
• and
• a shell frame supported by the support base and having an inner surface configured to a shape of the body part and an upper flange, wherein the shell frame further comprises at least one clip, connected to the upper flange, that is configured to clip the shell frame to a body part positioning mask that is mountable upon the upper flange of the shell frame,
• wherein the at least one clip comprises at least one flexible spring arm connected to an outer edge of the upper flange and wherein the at least one flexible spring arm flexes in an outward direction from the outer edge of the upper flange to enable a mounting retention member to clip to or unclip from a surface of the body part positioning mask.
