摘要:
A wireless ultrasound probe has a probe case enclosing a transducer array, an acquisition circuit, a transceiver and a battery. The probe also includes a loudspeaker which produces audible sounds during use of the probe. The loudspeaker, which may be a piezoelectric loudspeaker, issues an alert when battery power is low or signal strength of the wireless transmission is poor or nonexistent. The loudspeaker can provide user feedback to the actuation of a button or control on the probe. The loudspeaker can provide haptic feedback during use of the probe, and can be used to produce audio Doppler tones or heart sounds during probe use.
摘要:
A system and method of controlling the pressure within a surgical tourniquet so as selectively to occlude blood flow within a portion of a limb of a patient, wherein the pressure within an inflatable cuff surrounding a portion of a limb of a patient is changed by automatically opening a first valve connected to a controller and located within a first conduit between an inflatable bladder and the inflatable cuff, when the pressure in the inflatable cuff is different from that in the inflatable bladder. In another aspect, a system and method of controlling the pressure within a surgical tourniquet so as selectively to occlude blood flow within a portion of a limb of a patient within five seconds. In another aspect, a system and method of detecting a leak in a surgical tourniquet. In another aspect, a surgical tourniquet that, from an inflated state, may enter a deflated state, a set state, a default display state, or an off state. In another aspect, a surgical tourniquet mounted in a housing selectively closed around a pole, wherein the center of gravity of the housing is located within the pole, In another aspect, a surgical tourniquet controlled by means of a graphical user interface. In another aspect, a method of detecting a stuck solenoid valve in a surgical tourniquet.
摘要:
A needle guide having a semi-compliant shell design and locating means for attachment to an ultrasound transducer. The needle guide improves over the prior art in its reduced complexity, its low-profile formed fit to the transducer, a positive guide locking feature when the needle holding pin is in the closed position, and its ease of attachment over a sterile cover. The improved design is conducive to low-cost manufacturing methods which employ materials that can be autoclaved, gas-sterilized, or liquid disinfected.

An ultrasonic diagnostic imaging system is provided in which the scanhead connectors are elevated and tilted upward. This is provided by a tilted card cage with a backplane mount for the scanhead connectors which extends above the top of the card cage. The elevated and tilted scanhead connectors provide a comfortable position and orientation for the system operator when inserting and removing probe connectors, and the elevated position keeps the probe cables well above the floor and entanglement with the wheels.

An ultrasonic diagnostic imaging system includes an articulating flat panel display for viewing images produced by the ultrasound system. The flat panel display is articulated to a desired viewing position by gripping the periphery of the display screen and moving the display screen to the desired viewing position with one hand. The bezel around the display screen is contoured and formed of a robber-like material which can be engaged with the thumb of a user's hand, and the back of the display enclosure opposing the bezel contains perforations which can be engaged with fingers of the user. The gripping perforations also provide ventilation of the flat panel display.
摘要:
An ultrasound system has a plurality of locations around the control panel at which a probe holder may be located. The probe holder may be mounted by the user on the left or right side of the control panel to accommodate left-handed or right-handed users. The illustrated embodiments show different mechanisms by which a probe holder may be movably mounted to the ultrasound system. In one embodiment a plurality of probe holders swing or slide out for use, and stow inside the system when not in use.
摘要:
A cart-borne ultrasound system is described which includes a portable cart holding the electronic circuitry of the ultrasound system, a control panel for controlling the ultrasound system, and a display. The control panel is supported by an articulating mechanism which enables the control panel to be raised and lowered to accommodate operators of different height, and enables the control panel to move toward and away from the user to accommodate users in the sitting or standing positions. In a preferred embodiment the articulating mechanism comprises a parallelogram-shaped linkage which also maintains a constant angle of inclination of the control panel as it is raised and lowered.
