PREFERENTIAL VISUAL ACUITY TEST CABIN

Abstract

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.

Description

DESCRIPTION OF FIGURES

[0016] In order to complement this description, and so as to obtain a better understanding of the features of this invention, and according to a preferred practical performance of the same, an attached description follows with a set of drawings, wherein its functioning was presented, in an exemplificative but not limitative form,.

[0017] FIG. 1 represents an exploded view perspective of the structure making up the mentioned booth;

[0018] FIG. 2 reveals a perspective view of the assembled cabin;

[0019] FIG. 3 shows a longitudinal view AA, indicated in the former figure, in respect to the enlarged detail;

DETAILED DESCRIPTION OF OBJECT

[0021] In respect to the illustrated drawings, this patent of invention refers to “A BOOTH FOR THE PREFERRED VISUAL ACUITY TEST”, more precisely discloses a booth(10) of the type to quantify the visual acuity irrespective of the patient's verbal information (pc) by means of the ‘teller’ technique in such environments as offices and clinics, by a specialized professional.

[0022] According to this invention, said booth(10) comprises a modular structure (20) made in wood, drywall, PVC or another type of material, in a way to make up an isolated environment (AS) for the patient (pc) to perform the preferred acuity test through the reading of ‘Teller’ cards (CT) laid out in the visualization area (21a) foreseen at the central portion of the sliding movable wall (21), through rollers (rd) on rails (30) and (31), installed on the ground (22) and ceiling (25), sustained by profiles (25a). All the modular structure (20) presents a white and opaque tone, as well as a proper lighting (i1), which is controlled and proper, according to the test.

[0023] In front of the movable wall (21) and coplanar to the rear wall (24) of booth(10), a seat (27) is installed to accommodate the patient (pc) and an eventual companion.

[0024] The sliding of the movable wall (21) makes up the distance adjustment (d10 between the patient (pc) and the visualization area (21a) of cards (CT), where the minimum distance is equivalent to 38 centimeters and the maximum distance corresponds to 84,55 centimeters of the accuracy indicated for test effectivity, according to the patient's features (pc).

[0025] In a preferred constructive version, said modular structure (20) presents ideal height (t1), length (c1) and width (I1), designed for accommodation in office, clinics or similar rooms, and comprises a floor (22), sidewalls (23), a rear wall 24) and ceiling (25), in a way to compose a frontal bay (VF) provided with a frame (26) and where a movable wall (21) is installed, with width (I2) and height (t2) reduced in respect to width (I2′)and eight (t2′) of bay (vF). An opening (23a) is provided in one of the side walls 23), liable to receive a hinged door (27) fixed by hinges (db) and provided with a handle (Px).

[0026] The visualization area (21a) of the sliding wall (21) carts (CT) comprises a rectangular central cut-out (21b), from whose outer face a support (21c) with ‘L’ shape developed, mirrored in a way to cover the cut-off (21b), forming an interstice (IT) for the card (CT) assembly. Said support (21c) foresees a central hole (21d) that, upon the assembly of the card (CT), becomes aligned with the hole (o1) of the same for the professional to visualize the patient (pc) reactions who, in turn is accommodated in the booth(10).

[0027] When this invention is put into practice, it is certain that modifications concerning certain construction details and form are liable to be introduced, without implicating to deviate from the fundamental principles clearly presented in the set of claims, it being thus understood that the terminology used had no limitation purposes.
