Abstract: A central server controls the receipt and analysis of patient medical data and patient information. The central server receives patient medical data and patient information from a remote computer. A storage system stores the received patient medical data, patient information, and the associated medical report prepared at analysis workstations at any location after analysis of the patient medical data. A processor controls access to and analysis of the patient medical data by analysis workstations and controls access to the medical report. The central server transmits the patient medical data to and receives the associated medical report from analysis workstations. The central server transmits the medical report associated with the patient medical data to the remote computer. Also, a method controls the acquisition and analysis of patient medical data over a network by a central server from a remote computer operably interconnected by the network with the central server.

Abstract: A system and method for triggering an external device in response to an electrocardiogram signal. In one embodiment the method includes determining a peak in the electrocardiogram signal, determining if the electrocardiogram signal is rising or falling at the peak in the signal and triggering a device in response to the rising or falling peak. In one embodiment of the invention an external trigger signal is produced only a rising peak is detected. In one embodiment, the system includes a microprocessor, a peak detector and a trigger circuit. The trigger circuit outputs a trigger signal to an external device when signaled by the peak detector and not inhibited by a signal from the microprocessor.

Abstract: A wireless patient monitoring system. In one embodiment the system has a first patient monitoring subsystem including a plurality of sensors and sensor modules; and a processor-transceiver in communication with the plurality of sensors and sensor modules; and a first clinician display subsystem including a processor-transceiver. The processor-transceiver of the first clinician display subsystem broadcasts, on a first predetermined frequency, the frequency the processor-transceiver of the first clinician display subsystem will use to communicate with the processor-transceiver of the first patient monitoring subsystem. The processor-transceiver of the first patient monitoring subsystem then transmits and receives data on the frequency that the processor-transceiver of the first clinician display subsystem will use to communicate with the processor-transceiver of the first patient monitoring subsystem.

Abstract: A central server controls the receipt and analysis of patient medical data and patient information. The central server receives patient medical data and patient information from a sensor or a remote computer. A storage system of the central server stores the received patient medical data, patient information, and the associated medical report prepared by the analysis software on the central server after analysis of the patient medical data. The medical report associated with the patient medical data is transmitted from the central server to the remote computer. Also, a method controls the acquisition and analysis of patient medical data over a network by a central server from a remote computer operably interconnected by the network with the central server.

Abstract: An inflatable bladder supports the body of a person and relieves pressure on a portion of the body not engaging the bladder. The bladder has at least one rear chamber adapted to receive and maintain a first charge of fluid. At least one front chamber supports the legs of the person and has two support legs. The support legs are spaced apart from each other to form a channel between the support legs. The channel is sized and shaped for placement beneath a portion of the body to relieve pressure on the portion. The front chamber is adapted to receive and maintain a second charge of fluid separately from the rear chamber.

Abstract: The invention is a central server configured to control the receipt and analysis of patient medical data and patient information. The central server controls access to the patient medical data by an analysis workstation that is responsive to a medical specialist. The analysis workstation analyzes the patient medical data and prepares a medical report associated with the patient medical data. The central server comprises a first communication interface for receiving patient medical data and patient information from a remote computer and for transmitting the medical report associated with the patient medical data to the remote computer. A storage system stores the received patient medical data, patient information, and the associated medical report. A processor is configured to control access to and analysis of the patient medical data by the analysis workstation and the medical specialist and is configured to control access to the medical report.

Abstract: The configuration and arrangement of the instrument greatly facilitate safe placement of the instrument and an associated endotracheal tube. The instrument includes a handle with an arm extending therefrom. The arm includes a base portion and a distal lifter portion preferably having an angle between 5° and 85°, inclusive, and the lifter is sized and shaped to engage or lift the patient's epiglottis, thereby to expose the glottis. In a preferred embodiment, the base portion and lifter portion are substantially the same length, and a viewing device, which is preferably a Charged Coupled Device (“CCD”) or Complementary Metal Oxide Semiconductor (“CMOS”) camera positioned near the transition portion between the base and lifter portions, is aligned to provide a perspective view toward the distal end of the lifter. Lights, which are preferably LED units, are positioned toward the distal end of the lifter to facilitate viewing.

Abstract: A femoral arterial or venous compression device for post-catheterization hemostasis includes a supporting frame (base (1), shaft (2) and arm (4)), and an inflatable unit (carriage (6), bellows (7), disk (8), and pad (9)). The supporting frame is fixed on the human body in line with the incision site in order to bring the pad (9) exactly over and in touch with the latter. The bellows (7) are inflated thus compressing the incision site with the pad (9) for all the time needed to reach complete hemostasis. The pressure on the incision remains constant during the compression period and can be regulated and monitored using a medical sphygmomanometer.

Abstract: A system used by a technician for evaluating a Holter ECG tape having a signal representing a series of waveforms thereon and for generating a report reflecting the evaluation. A tape reader generates from the ECG tape an analog signal representative of the ECG waveforms recorded on the tape. An A/D converter converts the analog signal into a digital signal. A computer including a data bus, a memory, a processor controls the operation of the system. A display displays waveforms representing the ECG. A storage device is connected to the data bus. A direct memory access device moves the digital signals from the converter to the memory for storing the digital signal in the storage device. The converter provides at least a 12 bit a digital signal corresponding to the analog signal and includes means for converting the 12 bit digital signal to an 8 bit digital signal.
