Abstract:
A CPR chest compression machine includes a retention structure configured to retain a patient's body, and a compression mechanism configured to perform automatically CPR compressions to the patient's chest. The CPR machine also includes a camera coupled to the retention structure or to the compression mechanism. The camera has a field of view that spans at least a certain portion of the patient's body, and is configured to acquire an image of what is spanned by its field of view. The image may be stored in a memory, displayed, transmitted, analyzed to diagnose the patient, detect shifting of the patient within the CPR machine, etc.
Abstract:
A CPR chest compression machine includes a retention structure (140) configured to retain a patient's (182) body, and a compression mechanism (148) configured to perform automatically CPR compressions to the patient's (182) chest. The CPR machine also includes a camera (161) coupled to the retention structure (140) or to the compression mechanism (148). The camera (161) has a field of view (162) that spans at least a certain portion of the patient's (182) body, and is configured to acquire an image (407) of what is spanned by its field of view. The image (407) may be stored in a memory (130), displayed, transmitted, analyzed to diagnose the patient, detect shifting of the patient within the CPR machine, etc.
Abstract:
A crutch includes a grip and a forearm support that are coupled to an elongated member that extends from the forearm support to the ground. The inner surface of the forearm support can correspond to a digital representation of a forearm of the patient and the outer surface of the hand grip can correspond to a digital representation of a palmar surface of the patient's hand in at least a partially closed position.
Abstract:
Provided according to embodiments of the invention are methods of improving the effectiveness of chest compressions as part of cardiopulmonary resuscitation (CPR). Such methods include monitoring PPG signals from a PPG sensor secured to a nose during at least one chest compression and increasing, decreasing or maintaining a at least one of the depth, duration and frequency of at least one subsequent chest compression based on a waveform parameter of the PPG signals. Related devices and systems are also provided.
Abstract:
The invention generally relates to devices that demonstrate the function of ophthalmic lenses that modify human color perception and to methods and devices that simulate color vision deficiency or color blindness.
Abstract:
A device for stimulating saliva production in a subject includes a source of vibratory motion and a saliva stimulation assembly configured to elicit a salivary response by delivery of a vibratory stimulus. The saliva stimulation assembly includes one or more contact points coupled to the source of vibratory motion and configured to be placed against one or more stimulation sites on one or more portions of skin of the subject. The source of vibratory motion is configured such that, when the source of vibratory motion is operating and the one or more contact points are placed against the stimulation site, the one or more contact points vibrate at a stimulation frequency that produces a stimulus transmitted via the at least one portion of skin to the one or more salivary glands to stimulate saliva production by the one or more salivary glands.
Abstract:
A system for testing the vision of a subject incorporating eye movement tracking is disclosed herein. The system includes a head motion sensing device configured to measure a velocity or speed of a head of a subject, an eye movement tracking device configured to measure an eye movement of the subject, a visual display device configured to display one or more visual objects so that the one or more visual objects are visible to the subject; and a data processing device operatively coupled to the head motion sensing device, the eye movement tracking device, and the visual display device, the data processing device being specially programmed to carry out the steps of the vision tests. A method for the testing the vision of a subject incorporating eye movement tracking is also disclosed herein.
Abstract:
Examples of a motion system are disclosed. The motion system comprises a plurality of Stewart platform based actuators connected one to each another forming a desired modular configuration. Each of the plurality of actuators is controlled by a central controller that is configured to independently control the plurality actuators and adjust in real time their position, orientation and motion trajectory. The plurality of actuators are arranged in the desired configuration, shape and size to provide motion system that can mimic a natural motion/gait of human or animal body.

Abstract:
A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is purposely sub-optimal for circulation at least some of the time, and especially when it is detected that the patient has regained consciousness. An advantage can be that the patient may thus faint again, and therefore perceive less of the unpleasant experience of the mechanical chest compressions that the CPR system continues to perform on them as it preserves them alive.
