摘要:
An ear inspection device configured for being at least partially introduced into an external ear canal for determining an ear condition, such as temperature, in particular at the subject's eardrum, wherein the device comprises an infrared sensor unit configured for detecting infrared radiation from the ear, and an electronic imaging unit configured for capturing images based on radiation in the visible range from the ear, wherein the electronic imaging unit exhibits at least one optical axis arranged such that it can be radially offset within the ear canal, and wherein the infrared sensor unit exhibits a visual axis arranged such that it can be positioned centrically within the ear canal or radially offset within the same semicircle, especially the same quadrant, of the cross section of the ear canal.

A method, system, and device for detecting whether an expandable member completely occludes an anatomic passageway allows a user, such as a physician, clinician, or surgeon, to perform a medical procedure more efficiently and increases the procedure's chances of success. An incomplete occlusion can be immediately detected by monitoring the pressure difference across the expandable member. Through this method, a user can quickly diagnose the problem and reposition the expandable member in the anatomic passageway. In particular, in a cryoablation procedure, devices incorporating this method can help ensure a uniform and complete lesion in the pulmonary vein to electrically isolate the pulmonary vein from the atrium, thus preventing atrial fibrillation.

A device for facilitating the examination of an orifice is disclosed. The device comprises mounting means (12) for a light source (14) for illuminating the orifice, a connector (28, 128, 228) for detachably mounting a dilator (16, 116, 216) for insertion into and dilation of an orifice, and dilator actuating means (15, 18, 20, 215, 218, 220) for operating a mounted dilator (16, 116, 216). The mounted dilator (16, 116 216) includes operative parts able to move apart from one another.

A hearing screening system for testing hearing abilities of a patient includes an otoacoustic emission (OAE) module operable to perform OAE tests, a tympanometry (tymp) module operable to perform tymp tests, and at least one probe in communication with at least one of the OAE and tymp modules. The probe includes a probe tip that is configured to be positioned within an ear canal of a patient.

An otoscope permitting examination of a patient's ear is defined by an instrument head including a proximal end and a distal insertion portion that is insertable into the ear. The otoscope includes an imaging lens train disposed within the instrument head, wherein each of the imaging lens train, an eyepiece and a distal opening of said insertion portion are aligned along an optical axis. The otoscope further includes a focusing mechanism for selectively moving at least one of the imaging lens train and the optics contained within the eyepiece relative to one another along the optical axis. The imaging lens train and the optics in the eyepiece define an optical system such that an entrance pupil is substantially located in the distal insertion portion of the instrument head, thereby enabling the entire tympanic membrane to be viewed at once by the user.
摘要:
A method and a probe for conducting an audiologic test is disclosed. The probe extends along a longitudinal axis from a first end to a second end, the first end configured for insertion into an ear-canal of a person and the second end opposite to the first end. The probe comprises a probe part between the first end and the second end; wherein the probe part has a first port; and the probe further comprises a holder fixed to the probe part, said holder being configured to being held by an operator of the probe, e.g. in a three-finger grip.
