600555000 | Sensitivity to thermal stimulus | 9 |
20090124926 | ENVIRONMENT CONTROL DEVICE, ENVIRONMENT CONTROL METHOD, ENVIRONMENT CONTROL PROGRAM, AND ENVIRONMENT CONTROL SYSTEM - Comfortable sensation of living bodies is estimated, considering individual differences in biological information on the living bodies staying or residing in a common space, and stimulation contents is properly controlled. A stimulation generator | 05-14-2009 |
20090270757 | THERMAL PROBE FOR QUANTITATIVE SENSORY PAIN TESTING - Devices, systems, and methods for sensory quantitative pain testing in subjects are provided. The devices, systems, and methods are particularly useful for conducting sensory tests following thermal stimuli applied to subjects in clinical settings. The devices, systems, and methods may be used for diagnosing painful neuropathies in subjects. | 10-29-2009 |
20100241025 | COLD REFLEX TESTER - The present invention provides a cold reflex tester, in which an electrical device capable of controlling the temperature and maintaining a fixed temperature at a low level based on an electrical signal from a controller is used in a cold stimulator that is brought into contact with a subject's body as a means for applying a cold stimulus to the subject's body. Thus, it is possible to apply a more constant stimulus to a subject's body during measurement and thus improve the reliability of the measurement. | 09-23-2010 |
20100331722 | Device and method for assessing operant facial pain - The subject invention concerns a method and device for assessing facial pain sensitivity exhibited by an animal. The device and method can be used, for example, to evaluate the effect of a disease state, drug, or other intervention, on facial pain sensitivity, such as orofacial pain sensitivity. In one embodiment, the device and method provide a way of assessing both heat and cold sensitivity (hyperalgesia and allodynia) in the facial region in a non-invasive manner. Additionally, since the animals can be kept unrestrained, there are less confounding factors such as stress, which are inherent to other facial pain testing techniques. | 12-30-2010 |
20110313314 | METHOD AND SYSTEM FOR DETECTING NEUROPATHY - The invention provides a system and method for detecting or monitoring neuropathy in an individual. The system of the invention includes a platform having a surface in which a plurality of stimulators is embedded. Each stimulator is configured to stimulate a region in a skin area when the skin area is applied to the platform. The stimulators may deliver thermal and/or vibrational energy to the skin region. In the method of the invention, a skin area is applied to platform and one of the stimulators is activated. A minimal stimulation is determined that is sensed by the individual in a skin region in contact with a stimulator. Neuropathy in the skin region in contact with the stimulator is detected if either the determined minimal stimulation is above a predetermined threshold, or if a stimulation is not sensed before a magnitude of the stimulation reaches a predetermined maximal magnitude. The process is then repeated with other stimulators. | 12-22-2011 |
20120197154 | DEVICE FOR SENSITIVITY TESTING - Devices and methods for sensitivity testing are provided. Disclosed devices include a flexible catheter body having a distal end and a proximal end, a peltier element, a contact element located at or near the distal end of the catheter body that can be heated or cooled by applying a voltage to the peltier element, and a contact sensor for detecting contact between a contact surface of said contact element and tissue to be tested. | 08-02-2012 |
20130245491 | MULTI FUNCTIONAL MEDICAL DEVICE FOR SENSORY DIAGNOSTICS - A method and a device are disclosed for the diagnosis of sensory sensitivity in medical patients, including using a multifunctional medical device which may be utilized to test patient's skin sensitivity to a variety of stimuli and conditions such as heat or temperature, vibrations, electrical shock, pressure, pain, burning sensation, and the like. In some embodiments, the medical device includes a multifunction diagnostic head which can provide various stimuli at its tip, such as various temperatures, vibration, electrical shock, pressure, pain, and other stimuli which is detected by human skin sensory cells. In other embodiments, each of these stimuli may be provided by a separate removable diagnostic head. In still other embodiments, a removable diagnostic head may provide several, but not all, of the desired sensory stimuli listed above. | 09-19-2013 |
20140213928 | MINIATURIZED THERMAL SYSTEM FORMED WITH SEMICONDUCTOR MATERIAL WITH MEDICAL APPLICATIONS - In a first embodiment, a portable, battery-operated, minimally invasive small fiber neuropathy testing and diagnostic device, microcontrolled and interfacing with wireless powering to a wireless communications device is being disclosed. Said device is constructed out of an intra-epidermal thermal stimulus consisting of an electronically heated temperature-controlled polymer covered semiconductor material | 07-31-2014 |
20150065909 | CENTRAL SENSITIZATION DIAGNOSIS DEVICE AND METHOD FOR OPERATING SAME - An object of the present invention is to provide a system for performing objective examination of central sensitization, in particular, a system for objectively determining the presence or absence of central sensitization in a chronic pain patient. The present invention provides a device for diagnosing the presence or absence of central sensitization, the device including: stimulation output means for outputting thermal stimulation which can be perceived by a subject; first input means capable of inputting a measurement start signal; second input means capable of inputting a measurement end signal; and measurement control means for measuring time between an input signal from the first input means and an input signal from the second input means. The measurement control means determines that the central sensitization is present when the time between the input signal from the first input means and the input signal from the second input means is longer than t seconds (where t represents 30 seconds or more and less than 90 seconds). | 03-05-2015 |
