    摘要: A method is disclosed for inflating an inflatable vest to assist the heart in patients suffering from heart failure. The inflation of the vest is synchronized with on-set of the systole phase of the heart, when the left ventricular compresses to force blood out of the heart and through the aorta. The inflated vest compresses the patient's chest and increases the intrathoracic pressure. This increase in pressure assists the heart in moving blood out of the heart and through the aorta. In addition, the vest is arranged to leave the patient's abdomen free of restraint so that the increase in intrathoracic pressure due to the vest moves blood into the abdomen, and to allow the abdomen to dynamically recoil in response to the vest inflation. In addition, ECG signals from electrodes applied to the patient are processed to trigger the vest inflation in real time with the current heartbeat cycle, such that the vest inflation is triggered when the heart begins to contract. A controller provides an adjustable signal blanking period to avoid noise components following the QRS complex.

    摘要: A surgical cast cutter or other power tool comprises a main tool section and a complementary hose section releasably secured to the tool section rearwardly thereof. The sections have respective cooperating rib means formed therein which slidably engage each other (in a direction transverse to the longitudinal axis of the tool section) as the sections are brought together; and the sections are retained by a releasable latching means. A low-voltage electric motor in the tool section drives a transmission which oscillates a cutter mounted forwardly of the tool section. A debris conduit in the tool section communicates with an opening formed in the hose section when the sections are joined together. The hose section carries a flexible vacuum hose communicating with the opening therein, thereby facilitating removal of dust particles generated during operation of the cutter to remove a plaster cast. A low-voltage cable is carried by the vacuum hose and is connected to electrical contacts carried by the hose section. These contacts engage corresponding electrical contacts carried by the tool section, when the sections are brought together, for energization of the motor through a switch carried by one of the sections. The sections have respective side housing edges which are inclined with respect to the respective cooperating rib means; these side housing edges are brought into substantial abutting engagement when the sections are fully joined. The opening in the hose section, as well as the rearward opening of the debris conduit, are also inclined with respect to the respective cooperating rib means to assure good sealing engagement therebetween when the sections are fully joined.

    摘要: A method of building classifiers for multimodal neurological assessment is described. The method comprises the steps of extracting quantitative features from a plurality of physiological and neurocognitive assessments, and selecting a subset of features from the extracted pool of features to construct multimodal classifiers. A device for performing point-of-care multimodal neurological assessment is also described.

    摘要: A blower pressure source has been integrated into a vest cardiopulmonary resuscitation (CPR) system. The vest includes a bladder that cyclically inflates and deflates to provide automatic CPR to a patient in cardiac arrest or needing circulatory assistance to a patient with a beating but weakened heart. The blower continuously provides air at relatively low pressure to inflate a bladder in the vest. The maximum pressure of the blower corresponds to the desired peak vest pressure. A relatively simple valve, solenoid and timing controller is used to apply the blower air in cycles to inflate the bladder.

    摘要: A device and method for assessment of traumatic brain injury (TBI) is described. The device is configured to acquire brain electrical signals from a patient's forehead using one or more neurological electrodes. The acquired brain electrical activity data is subjected to artifact rejection and feature extraction, and a subset of features are then combined in at least one classifier function. The classifier functions statistically place a patient in one of four categories related to the extent of brain dysfunction: 1) normal brain electrical activity; 2) abnormal brain electrical activity consistent with non-structural injury with less severe manifestations of functional brain injury; 3) abnormal brain electrical activity consistent with non-structural injury with more severe manifestations of functional brain injury; and 4) abnormal brain electrical activity consistent with structural brain injury.
