Disposable contamination prevention liners for MRI machines

A liner pack for mounting on a medical device having a bore with a curved bore wall surface and an open front end, the liner pack comprising:

• a backing layer having a top side and a bottom side;
• a stack of disposable multi-layered liner sheets secured to the bottom side of the backing layer;
• and
• mounting means for supporting the liner pack within the bore in a generally curved configuration to substantially cover the bore wall surface,
• wherein the mounting means comprises attachment devices on the top side of the backing layer configured to cooperate with locking receptacles strategically secured to the curved bore wall surface to support the liner pack substantially flush against the bore wall surface in its generally curved configuration,
• wherein the attachment devices comprise locking pegs having a T-shaped cross-section key extending upwardly from a base portion;
• and
• wherein the locking receptacles comprise a body having a T-shaped cross-section keyway disposed inwardly through a front portion of body, the T-shaped cross-section keyway having a shape complementary to the T-shaped cross-section key to slidably receive the key such that the locking pegs and the locking receptacles remain locked together in assembly.

• a backing layer having a top side and a bottom side;
• a stack of disposable multi-layered liner sheets secured to the bottom side of the backing layer;
• and
• mounting means for supporting the liner pack within the bore in a generally curved configuration to substantially cover the bore wall surface,
• wherein each liner sheet in the stack has a trailing end and a pair of opposing flaps extending outwardly from the trailing end, the opposing flaps having an outer edge, and
• wherein the flaps include a pull tab extending outwardly from the outer edge of the flaps to permit an individual liner sheet to be separated from an underlying sheet in the stack of liner sheets.

• wherein the mounting means comprises a contour-shaped insert attached at the longitudinally extending outer edge that cooperates with complementary contour-shaped grooves defined in elongated guide rails adapted to be affixed inside the bore to support the liner pack substantially flush against the bore wall surface in its generally curved configuration.

A method of covering a curved bore wall surface of a medical device having a bore defined therein which extends from a front face to a rear face of the device to maintain a sterile environment, the method comprising:

• providing a sterile liner pack including a backing layer having a top side and a bottom side, a stack of disposable multi-layered liner sheets secured to the bottom side, and mounting means for supporting the liner pack within the bore in a generally curved configuration to substantially cover the bore wall surface;
• securing locking receptacles adapted to cooperate with the mounting means to the curved bore wall surface at strategic locations to hold the liner pack substantially flush against the bore wall surface in its generally curved configuration;
• contouring the liner pack prior to insertion inside the bore to a shape generally corresponding to the curved bore wall surface;
• and
• inserting the contoured liner pack inside the bore toward the rear face of the device such that the mounting means engage the locking receptacles secured to the curved bore wall surface to hold the liner pack substantially flush against the bore wall surface in its generally curved configuration,
• wherein the mounting means comprises a plurality of locking pegs on the top side of the pack backing layer, each having a T-shaped cross-section key, and the locking receptacles secured to the bore wall surface each comprises a body having a complementary T-shaped section-section keyway, and
• wherein inserting the contoured pack toward the rear face of the device further comprises slidably receiving the T-shaped cross-section keys in the T-shaped cross section keyways to lock the locking pegs and the locking receptacles together in assembly to hold the liner pack substantially flush against the bore wall surface in its generally curved configuration.
