DETAILED DESCRIPTION OF THE INVENTION

[0027] This disclosure is directed to example systems and assemblies for providing modular goggle assembly to assist in the diagnosis and treatment of vestibular disorders. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of example embodiments. It will be evident to one skilled in the art, however, that embodiments can be practiced without these specific details. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the claims included herein.

[0028] In certain embodiments, modular goggle assemblies constructed in a manner consistent with the present disclosure use infrared cameras and, optionally, virtual reality scenes to diagnose and treat vestibular disorders in patients experiencing dizziness or vertigo. Upon diagnosis of any such disorder, a treatment plan is developed and a virtual reality configuration of the disclosed modular goggle assembly is employed to administer treatment.

[0029] FIG. 1 depicts a modular goggle assembly 100 in accordance with an embodiment of the present invention. In this infrared camera configuration, the assembly 100 is comprised of an ocular portion 110, a barrel portion 120, and a cap portion 130. In embodiments, the ocular portion 110 further includes anchors 170 for connecting to a headgear 188 that permits comfortable and secure attachment of the goggle assembly 100 to the patient's head without the use of their hands.

[0030] As illustrated by FIG. 2, the ocular portion 110 is comprised of a viewing section 140 that, in embodiments, has two apertures 150 formed therein. The ocular portion further comprises a proximal side 112 that is patient-facing and has a proximal outer rim 114 shaped to fit a patient's face. For purposes of assisting with blocking light from outside the goggle assembly 100 as well as for comfort, a cushion 160 is disposed on the proximal outer rim 114 and, in an embodiment, is removable so it can be replaced or disinfected after use. Cushion 160 is connected to the proximal outer rim 114 with hook and loop fasteners, magnets or a mechanical snap-in or other fitted, light-proof connection. In another embodiment, the materials used for the cushion are medical-grade so that they are readily cleanable and hypo-allergenic.

[0031] The distal outer rim 116 of the ocular portion 110 comprises an attachment element 305 so that it can cooperatively connect with another module or portion of the goggle assembly. As illustrated in FIG. 3, the barrel portion 120 has a mated attachment receptor 315 that receives the attachment element 305 and enables a light-proof connection between the portions. In embodiments, the connection can be a male/female fit such as a snap fit, as shown, or a tight channel fit. In other embodiments, the connection can be magnetic or even via a hook and loop fastener as is known in the art. Regardless of connection type, in an embodiment, all light is blocked from passing through the connection so that the diagnosis or therapy is uninterrupted. With continued reference to FIG. 3, an embodiment of the barrel portion has a left eye column 325 and a right eye column 335, which provides flexibility in diagnosis and treatment.

[0032] In the illustrated embodiment, the barrel portion 120 has a portion of the mated attachment receptor 315 situated about its proximal outer rim 122, such that the edge cooperatively and securely connects to the attachment element 305 of the distal outer rim 116 of the ocular portion 110. The barrel portion 120 also comprises an adjustable focusing plane 175 and comprises a distal outer barrel edge 124 that cooperates with the cap outer edge 132 to provide a light-proof connection with the cap portion 130. As also illustrated by FIG. 5, an adjustment dial 178 can be employed to move the adjustable focusing plane 175 closer to or further away from the ocular portion 110 in order to help with focus of the infrared cameras 190 on the eyes of the patient. In embodiments, the barrel contains a divider 350 that creates a left chamber and a right chamber to permit the cameras 190 to focus on one eye at a time and so that different content can be delivered to each eye when the assembly is in virtual reality mode.

[0033] In embodiments, a camera housing 180 is removably positioned in between the barrel portion 120 and the cap portion 130 with hook and loop fasteners, magnets or a mechanical snap-in or other fitted connection. With reference to FIG. 4, the camera housing 180 supports two infrared cameras 190 that are mounted on or in the camera housing 180 so that they face the patient's eyes. In embodiments, the cameras 190 provide information about the patient's eye movements during diagnosis or therapy related to a vestibular disorder or other illness, injury, or disease. In embodiments, the cameras provide data to a computer or display 1000 as illustrated in FIG. 10. The connection to the computer or display 1000 can be wireless or wired 400. In embodiments, the wired connection 400 to the computer or display 1000 is via the USB protocol as is known in the art, but other connections and protocols will be readily apparent to those of skill in the art. The computer 1000, as is known in the art, will comprise at least a processor and a connected memory capacity for storing and running therapeutic or diagnostic routines and capturing and storing infrared camera output for analysis by a clinician.

[0034] With continued reference to FIGS. 2 and 3, the cap portion 130 has a cap outer rim 132 that, in embodiments, is formed as an attachment receptor that is designed to mate with and receive an attachment element just as previously discussed with the ocular portion 110 and barrel portion 120 connection. In embodiments, the attachment elements and receptors can be reversed so that the element is on the portion further from the patient and the receptor is on the portion closer to the patient's face. In another embodiment illustrated in FIG. 11, the cap portion 130 can be attached to the barrel portion 120 in a friction mount using the convex tabs 1110 to connect with the complementary concave indentions 1120 so that the cap portion 130 is firmly attached and the assembly 100 is lightproof.

[0035] FIG. 6 illustrates an alternative embodiment of the modular goggle assembly 100 of the present invention. In this embodiment, an off-the-shelf Virtual Reality goggle, such as the Samsung Gear VR, has been modified in the viewing section 140, with the addition of light-blocking columns 610 fastened to the surface of the viewing section 140 to centered with the pair of apertures 150. To ensure darkness inside the chamber between the patient's eyes and the cameras 190, a pair of light blocking columns 610 are attached to the ocular portion 110 added in this embodiment to prevent light from the barrel portion 120 from entering the field of view of the cameras 190 when moving the adjustable focusing plane 175 within the barrel. This ensures proper operation of the cameras when they are in an infrared mode. Samsung Gear VR is a registered trademark of Samsung Electronics Co., Ltd.

[0036] FIG. 7 illustrates a plan view of a modular goggle assembly 700 in a virtual reality display configuration consistent with an embodiment of the disclosed invention. In this configuration a lens portion 720 is inserted in between the ocular portion 110 and the barrel portion 120. Again, a cap portion 130 is attached to the end of the barrel portion 120.

[0037] FIG. 8 is an exploded view of the modular goggle assembly 700 in the virtual reality display configuration. In this embodiment, there is no camera housing. Instead, there is a display device 810 such as a mobile phone or other device capable of displaying images or video as is known in the art that is inserted or otherwise attached in between the barrel portion 120 and the cap portion 130 in the same way as the IR camera housing was inserted into the infrared camera configuration. In embodiments, the display device 810 is connected either via a wired connection or wirelessly, to a computer 1000 as illustrated in FIG. 10 having at least a processor and a memory facility for storing and delivering one or more therapeutic or diagnostic programs to be displayed to the patient the course of treatment or diagnosis of a vestibular disorder.

[0038] Another difference between the infrared camera configuration and the virtual reality configuration is the addition of the lens portion 720. In an embodiment, the lens portion 720 includes lenses having different levels of magnification to optimize for specific virtual reality applications. The lens portion 720 may also include colored or filtered lenses that block or allow certain spectrums of light for a research functionality. In further embodiments, the lenses can have different shapes, such as concave, convex, or Fresnel.

[0039] FIG. 9 illustrates an isolated view of the lens portion 720. In addition to providing lenses of different magnifications and types, the lens portion enables the lenses to be placed at differing distances from the patient's eyes. In embodiments, the lens adjustment dial 920 is employed to move the lens barrel 930 closer or further from the patient when in use. Likewise, the width adjustment dial 910 moves the lens barrel holders 940 closer or further from each other to conform to different patients. In an embodiment, the lens adjustment dial 920 and width adjustment dial 910 are connected to a rack and pinion system to enable movement of the lens barrel holders 940 and lens barrels 930. In other embodiments, the dials 910, 920 are attached to gears that move the lens barrel holders 940 and lens barrels 930 in a manner known to those of skill in the art.

[0040] In certain embodiments, the modular goggle assembly 100 is used by a clinician who may go to a patient's house or may have several offices and may need to bring the modular goggle system with them to evaluate patients. Upon suspicion of some malady detectable through eye movements, the clinician may have the patient don the modular goggle assembly 100 in an infrared camera configuration as represented by FIG. 1. To the extent that a diagnosis is made by the clinician upon reviewing the eye movements of the patient, the clinician can quickly and optionally switch to a virtual reality display configuration, as demonstrated by FIG. 7, by removing the IR camera housing 180 from the cap portion 130 and inserting a cell phone or other properly sized display device 810 in the cap portion 130 as well as a lens portion 720 in between the ocular portion 110 and the barrel portion 120, if necessary.

[0041] It is hoped that a modular goggle assembly 100, constructed in accordance with the present disclosure, can be used by general practitioners and urgent care providers alike to quickly triage patients suffering from vertigo. Early diagnosis means faster treatment and faster treatment means an overall lower cost of healthcare.

[0042] While various illustrative embodiments incorporating the principles of the present teachings have been disclosed, the present teachings are not limited to the disclosed embodiments. Instead, this application is intended to cover any variations, uses, or adaptations of the present teachings and use its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which these teachings pertain and which fall within the limits of the appended claims.
