Preferential visual acuity test cabin
View Patent ↗A booth, for using the Teller technique to quantify visual acuity, irrespective of a patient's verbal ability booth comprises a modular structure, making up an isolated environment for the patient to perform the acuity test through the reading of Teller cards. The patient is accommodated in a visualization area at the central portion of a movable wall sliding via wheels on rails installed on the ground and ceiling by profiles. The modular structure presents a white and opaque tone, as well as its own lighting which is controlled and proper according to the test, in front of a movable wall and coplanar to a rear wall of booth. The movable wall sliding effects the distance adjustment between the patient and the visualization area cards where the minimum distance is equivalent 38 centimeters and the maximum distance is 55 or 84 centimeters as accuracy dictates, according to the patient's features.
1 . A booth preferred visual acuity test, a booth being operative to quantify visual acuity of a patient, irrespective of the verbal information about the patient (pc), wherein said booth preferred visual acuity test uses Teller cards for the patient, the booth preferred visual acuity test comprising:
an isolated environment (AS) within a modular structure ( 20 ) for the patient (pc) to perform the preferred visual acuity test through reading of Teller cards accommodated within a visualization area ( 21 a ), wherein the cards are laid out in a central portion of a sliding movable wall ( 21 ) and wherein the sliding wall has wheels (rd) on rails ( 30 , 31 ) are installed on the ground ( 22 ) and ceiling ( 25 ), the modular structure ( 20 ) presenting a white and opaque tone, as well as its own lighting (II), controlled and fit according to the test, wherein in front of the movable wall ( 21 ) and coplanar to the rear wall ( 24 ) of the booth ( 100 ) there is installed a seat ( 28 ) for accommodation of the patient (pc) and an optional companion;
the movable wall sliding ( 21 ) being operative to adjust distance (dl) between the patient (pc) and the visualization area ( 21 a ) of cards (CI), wherein the distance varies between a minimum distance of 38 centimeters and maximum distance of 84, varying in accordance with the features of the patient (pc) to optimize accuracy.
2 . The booth preferred visual acuity test according to claim 1 , wherein the modular structure ( 20 ) comprises at least one of:
wood, drywall, or PVC.
3 . The booth preferred visual acuity test according to claim 1 , wherein the modular structure ( 20 ) comprises:
ideal height (t′), length (cl) and width (I 1 ) for positioning in offices, clinics or similar rooms, and comprising a ground ( 22 ), side walls ( 23 ), a rear wall ( 24 ) and a ceiling ( 25 ), opening up upon a frontal bay (VF) provided with a frame ( 26 ), wherein a movable wall ( 10 ) is installed, with width (I 2 ) and height (t 2 ) reduced with respect to the width (I 2 ′) and height (t 2 ″) of bay (VF);
an opening ( 23 a ) in one of the side walls ( 23 ), fixed by hinges (db) and provided with a handle (Px); and
a visualization area ( 21 a ) for viewing the sliding wall ( 21 ) cards (CT) comprising a rectangular central cut-off ( 21 b ), the external face of the visualization area ( 21 a ) forming an L shape support ( 21 c ) in a way to cover the cut-off ( 21 b ), forming an intersection (IT) for an assembly of the card (CT), said cut-off ( 21 b ) forming a central orifice ( 21 d ) which, upon the assembly of the card (CT), aligns with the orifice (ol) of the same for the professional to visualize the reactions of the patient (pc), accommodated within the booth ( 10 ).
4 . The booth preferred visual acuity test according to claim 1 , wherein the booth preferred visual acuity test is performed by a professional in an office or a clinic.
