Abstract: Improved systems and methods for diagnosing an injury of a patient. The system and methods provide for more accurate scans of the injury thereby enabling a combat medic, a medical technician, or even untrained individuals to quickly diagnose the injury. By providing more accurate information, the systems and methods provide the technician with additional information regarding treatment options, such as whether to transport the patient or treat the patient in place, potential for aspiration, and other information about dangerous fluid build-up such as size, depth, and types of surrounding tissues, thereby increasing survivability of the patient. The systems and methods can also provide a diagnosis of the injury as well as suggestions on actions to take to treat the patient.

Abstract: An embodiment of the invention provides a method to measure fluid within a body cavity where data is received with an interface (210), the data being received from an ultrasound transducer. A three-dimensional sonographic image is generated with an image generator (220) connected to the interface (210), the three-dimensional sonographic image being generated from the data from the ultrasound transducer. The body cavity is identified in the three-dimensional sonographic image with an image processor (230) connected to the image generator (220); and, an area of fluid in the body cavity in the three-dimensional sonographic image is identified with the image processor (230). The volume of the area of fluid is calculated using the three-dimensional sonographic image and a stacked crescents process, a spherical fill process, a convex hull process, and/or a triangulation process.

Abstract: An umbrella-like scraper for cleaning tubes and pipes may include a scraper, an actuator and a hinge configured for selective deployment of the scraper by manipulation of the actuator.

Abstract: A cleaning tube may have an expansion portion that includes two or more slits. The cleaning tube may be deployed by linearly compressing the expansion portion, thus causing the tube to bulge into a disc through expansion of the slits. A sheath may cover the expansion portion to seal the slits. So deployed, the cleaning tube may be translated in a contaminated tube to remove contamination.

Abstract: An embodiment of the invention provides a method including obtaining ultrasonic images of one or more vessel to be catheterized with an ultrasonic imaging device 212 and identifying the center(s) of the vessel(s) with the ultrasonic images. One of the vessels is punctured with a needle 220 based on the identifying of the center of the vessel. A guide wire 230 is inserted into the vessel and maneuvered with guide wire ultrasonic feedback control. The guide wire ultrasonic feedback control includes obtaining ultrasonic images of the vessel and the guide wire 230 in the vessel, and displaying the ultrasonic images of the vessel and the guide wire 230 in the vessel to a user. A catheter sheath 240 is inserted over the guide wire 230 and maneuvered with sheath ultrasonic feedback control. The guide wire 230 is removed and a catheter 250 is inserted into the catheter sheath 240 and maneuvered with catheter ultrasonic feedback control.

Abstract: A system for assessing lung function in a patient is enclosed. The oxygen delivery system in the system (e.g., a ventilator or portable standalone system) preferably includes an oximeter sensor for receiving SpO2 from a patient. The assessing lung function in a patient includes an FiO2 adjust algorithm operable in logic circuitry in the ventilator that can control an oxygen fraction FiO2 provided to the patient in a closed loop fashion. In a preferred example, the algorithm controls FiO2 using the SpO2, but also displays a ratio of SpO2-to FiO2 (S/CLCF) as a function of time. One or more S/CLCF ratio threshold may be used to allow the clinician and/or the algorithm to understand a degree of lung injury, and to allow the algorithm to adjust FiO2 appropriately. Preferably, the algorithm keeps SpO2 to a range of 88-95%.

The systems and methods are then operable to produce at least one derived patient signal from at least one of the plurality of patient physiological signals. The systems and methods use the patient information, at least one of the plurality of patient physiological signals, and the at least one derived patient signal to provide at least one patient care recommendation.

Abstract: An embodiment of the invention provides a method for identifying internal trauma in a patient for pneumothorax, hemothorax and abdominal hemorrhage using ultrasound in B-modes with radial, longitudinal, phased array probes, and with M-mode for verification of lung sliding and lung point. Identifications are based on statistical classifications of image features, including A-line, B-line, lung sliding, barcode, sky, seashore, and beach patterns. For blood pools, a polygon is fitted to the boundary, and a cellular automaton extracts local interference patterns due to cavity shape. Logic is then applied to extractions to identify the trauma. With B-mode, feature extraction involves specialized algorithms operating at frame rate for tracking of features such as ribs and rib shadows, pleural line and fast changes in peak intensities along the pleural line. Results are presented on screen by means of highlighting and textual cues.

When the glove liner is inserted into a baseball fielder's glove, the pad underlies a heel of the glove and/or a palm of the glove and promotes catching a baseball in the webbing or pocket of the fielder's glove.
