摘要:
A brain function examining apparatus and others for performing an examination of a brain function by detecting a pupillary size of a subject's pupil are provided. The brain function examining apparatus includes a light source for illuminating the pupil, a pupillary detector for detecting the pupillary size, an index calculator for calculating, based on the pupillary size detected by the pupillary detector, a subject index indicative of a characteristic of the pupil, a database for storing a base index indicative of a characteristic of the pupil that can be used as reference, and an output unit for outputting the subject index, calculated by the index calculator, and the base index stored in the database.
摘要:
An apparatus for examining a subject's brain functions acquires two or more indexes of pupillary indexes that show the subject's pupillary characteristics, visual indexes that show the subject's visual system functions, intelligence evaluating indexes that are results of the an intelligence test carried out on the subject, and behavior evaluating indexes that show the results the subject's behavior examination. Two or more indexes are stored in a memory and outputted from an output unit. By combining two or more kinds of independent indexes, accurate determination of dementia cases and further the degree of senescence of brain functions can be achieved. In addition, the brain function examining apparatus puts together a number of a plurality of indexes by the multivariate calculation and converts the indexes into different values of fewer numbers.

This cognitive function training unit comprises an eye-target showing means for showing a movable eye-target on a display disposed in front of the subject's eye, an eye movement measuring means for measuring a position and/or movement of the subject's eye, and a judgment means for judging whether the subject can fixedly look at or follow the eye-target based on the position and/or the movement of the eye-target shown on the display and the position and/or the movement of the subject's eye measured by the eye movement measuring means, and the eye-target showing means shows the eye-target repeatedly while changing the position and/or the movement of the eye-target according to a judgment result of the judgment means. Therefore, it is possible to show a suitable eye-target according to a symptom of a patient, whereby it is possible to conduct training efficiently

摘要:
The perimeter comprises a display device 1, infrared light-emitting diodes 2, a CCD camera 3, a half mirror 4, an image processing device 5, a computer 6, and an operating switch 7. The computer 6 shows a fixed eye-target for fixing a line of sight of a subject and a light stimulus eye-target for giving a light stimulus to a pupil of the subject at a plurality of predetermined positions on the display device 1. The infrared light-emitting diodes 2 irradiate infrared light to an eye of the subject. The CCD camera 3 takes an image of the eye of the subject using the infrared light irradiated from the infrared light-emitting diodes 2. The image processing device 5 detects a pupil diameter of the subject based on the image taken by the CCD camera 3. The computer 6 measures a visual field of the subject based on the change of the pupil diameter of the subject detected by the image processing device 5. The feature of the present invention resides in that the display device 1 comprises a display device capable of adjusting background luminance of a screen and brightness of the light stimulus eye-target separately.

摘要:
The present invention aims to provide an orthodontic appliance capable of efficiently applying vibration to teeth to be aligned and enabling a treatment to be easily and safely continued even at home. This appliance is provided with a load applying mechanism and a vibration generating actuator. The load applying mechanism is mounted on teeth to apply a load for the malocclusion correction to a specified tooth in the teeth. The vibration generating actuator includes a contact portion that is inserted into a buccal cavity containing the teeth and can come into contact with a part of the load applying mechanism corresponding to the specified tooth or the specified tooth, and applies a vibration force from the contact portion to the specified tooth or the part of the load applying mechanism.
摘要:
The present invention concerns an orthodontic appliance for accelerating the tooth aligning effect and shortening the treatment period, and has an object to provide an appliance which can bring about higher aligning effect than usual ways by giving vibration to tooth to be aligned to activate bone remodeling of the targeted tooth and the alveolar bone and enhance the shift of the tooth. This appliance includes a vibrating element and a dental mouthpiece having the vibrating element built therein. The provision of the vibrating element in the dental mouthpiece facilitates the application of vibration and handling, and continues the treatment safely even at home. The inner shape of the dental mouthpiece serves aligning treatment as well as acceleration of the effect.
摘要:
This relates to a sleep apnea test sensor assembly (20) comprising multiple sensors to be used for diagnosis of sleep apnea syndrome, and a test equipment (30) comprising the same. The respective sensors each associate sensing data measured by a respective sensing section with time data of a clock unit, and store them in a storage unit so as to allow the sensing section to perform sensing at a predetermined period in response to a clocking operation of the clock unit, and set time of the clock unit in response to a synchronous signal input from outside. The respective sensors operate physically independently of each other, but can measure sensing data with the synchronization in time therebetween being secured, enabling accurate diagnosis of SAS.
