The present invention relates to a device for repair of a region within an ear via a natural orifice, the device comprising a body. The body comprises a first port for visibly identifying the region to be sealed, the region being inside the ear; and a second port through which a seal can be introduced into the ear through the device. The region comprises a perforation of a tympanic membrane of the ear and the device is a speculum. The present invention also relates to method for repairing a perforation in a tympanic membrane using the same device.

Described herein is a software-based simulator to provide speech and hearing students the ability to perform hearing screening training using a realistic interface similar to devices used to perform these tests, which provides results for Otoscopy, Tympanometry, and Audiometry testing, and assesses the students responses for correctness.

The present disclosure pertains to a method for diagnosing a middle ear disease comprising receiving one or more otoscopic image of a subject, pre-processing the one or more otoscopic image to obtain image data, inputting the image data to a trained network model, generating, using the trained network model, an output that characterizes the health of the subject with respect to the middle ear disease, and generating a diagnostic result based on the output, wherein the trained network model is based on a model selected from the group consisting of a MobileNetV2 model, a NASNetMobile model, and a DenseNet201 model.

An instrument head for attachment to a plurality of instrument handles having different power sources is described. The instrument head includes at least one light-emitting diode, and a controller. When the controller detects an instability in a voltage input from a power source in an instrument handle attached to the instrument head, the controller transitions from a normal mode of operation to a mitigation mode of operation. The mitigation mode of operation prevents an increase in output of the at least one light-emitting diode for a predetermined period of time.

Systems and methods may determine an amount of current being drawn by a light source and determine, based on the amount of current, a type of light source. Based on the type of light source, an amount of time associated with disabling the light source may be determined. A voltage may be supplied to the light source for the amount of time.

Disclosed are medical examination or diagnostic instruments and methods of operating such instruments. The method can include coupling an instrument head to a handle to form a medical examination or diagnostic instrument; detecting by the instrument head, a characteristic of the handle; and based at least in part on detecting the characteristic of the handle, determining, by the instrument head, a handle type associated with the handle, or detecting by the handle, a characteristic of the instrument head, and based at least in part on detecting the characteristic of the instrument head, an instrument head type associated with the instrument head. In some implementations, the emission of light can be controlled to be approximately linear in relation to a user input signal, as perceived by a user.
