Abstract

A unique mirror optical system reduces the anxiety of patients due to claustrophobia during magnetic resonance imaging or the like. A back surface mirror is mounted on a spectacle frame which is attached to the patient'"'"'s head with an adjustable elastic band. With the patient in the supine position, the mirror allows the patient to see over the head or feet to scenes placed on a distant surface. Since the patient can see "out", the confined feeling which triggers the claustrophobia response is greatly reduced or eliminated.

Claims

1. For use in the environment of an MRI scanner by a plurality of patients subject to claustrophobic type fears, the combination of:

(a) non magnetic lens holding means adapted to be worn by a patient;

(b) a set of pairs of lenses sized to easily press fit in and out of said lens holding means, each of said pairs of lenses having different optical correction so that a pair of lenses can be selected which approximate the correction required by each patient wearing said lens holding means;

(c) bracket means attached to said lens holding mean for mounting a mirror in the patient'"'"'s direct line of sight; and

(d) mirror means rotationally mounted in said bracket means for redirecting the patient'"'"'s vision in a direction that is substantially unobstructed by the scanner to a remote, preselected target, said mirror means including handle means extending through said bracket means for rotationally adjusting said mirror means to redirect the patient'"'"'s sight path, said handle means being mounted in elastomeric grommet means in said bracket means so that an adjustment, once made, is frictionally held in place,

whereby the elements of the combination are made of materials that do not affect the MRI scan but allow a patient whose direct vision is obscured by the scanner to view a scene other than the scanner.

2. The apparatus of claim 1, above, in which said bracket means are attached to said lens holding means by fastening elements through elongated slots in said bracket means, whereby the separation and angle of said mirror means can be adjusted.

3. The apparatus of claim 1, above, further including head encircling means attached to said lens holding means for adjustably holding the claimed combination in position on a wearer'"'"'s head.

4. The apparatus of claim 3, above, wherein said head encircling means includes an elasticized strap member of adjustable length.

5. The apparatus of claim 1, above, wherein said mirror means include a clear plastic substrate and a reflective coating deposited thereon.

6. For use in an environment subjecting a patient to claustrophobic type fears, the combination of:

(a) lens holding means adapted to be worn by a plurality of patients;

(b) a set of pairs of lenses sized to easily press fit in and out of said lens holding means, each of said pairs of lenses having different optical corrections so that a pair of lenses can be selected which approximate the correction required by each patient wearing said lens holding means;

(c) bracket means attached to said lens holding means for mounting a mirror in a patient'"'"'s direct line of sight; and

(d) mirror means including a plane mirror rotationally mounted in said bracket means for redirecting the patient'"'"'s vision in a direction that is substantially unobstructed to a remote, preselected target, said mirror means including handle means extending through said bracket means for rotationally adjusting said mirror means to redirect the patient'"'"'s sight path, said handle means being mounted in elastomeric grommet means in said bracket means so that an adjustment, once made, is frictionally held in place,

whereby the wearer is afforded a line of sight to a scene capable of having a calming effect to ameliorate claustrobic type fears.

7. The apparatus of claim 6, above, in which said bracket means are attached to said lens holding means by fastening elements through elongated slots in said bracket means, whereby the separation and angle of said mirror means can be adjusted.

8. The apparatus of claim 6, above, further including head encircling means attached to said lens holding means for adjustably holding the claimed combination in position on a wearer'"'"'s head.

9. The apparatus of claim 8, above, wherein said head encircling means includes an elasticized strap member of adjustable length.

10. The apparatus of claim 6, above, wherein said mirror means include a clear plastic substrate and a reflective coating deposited thereon.

11. The apparatus of claim 6, above, wherein all of the components of said combination are made of non magnetizable, non ferrous materials to which MRI scanners and the like are insensitive, whereby a patient who is substantially surrounded by MRI scanning equipment and whose direct vision is otherwise obscured by the MRI scanning equipment, is provided with an optical path to a remote scene thereby avoiding potential claustrophobic reactions.
