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 system and method of controlling the pressure within a pressure cuff of a surgical tourniquet so as selectively to occlude blood flow within a portion of a limb of a patient, wherein a sensor determines when flow past the tourniquet is occurring so that corrective action may be taken, such as by increasing the pressure in the tourniquet or by notifying an operator of the flow past the tourniquet. The present invention may use an acoustic sensor to detect Korotkoff sounds indicating incipient blood flow past the tourniquet. When such signals are detected, the tourniquet controller may either incrementally increase the pressure in the tourniquet, or if a threshold would be exceeded by such an increase, signal an alarm indicative of the blood flow.

摘要： A system for continuously supplying supplemental therapeutic oxygen to a patient to enhance atmospheric breathing comprising an oxygen supply source for continuously supplying low pressure low volume oxygen to a patient at relatively low pressures and relatively low flow rates to supplement normal atmospheric breathing; flexible oxygen supply tube devices for supplying oxygen from said oxygen supply source to the patient; and a continuous one-piece constant diameter flexible elongated tracheal tube member having a continuous constant diameter passage extending therethrough and being flexible when inserted into an operative position within the trachea to provide therein an intermediate curved side wall portion extending between a proximate end side wall portion having an unrestricted inlet opening therein located posterior of the neck of a patient and a straight distal side wall portion located in the trachea and extending downwardly therein and having an unrestricted distal end outlet opening located in upwardly spaced relationship to the bronchial tubes of the patient.

摘要： The present invention is a surgical tourniquet controller which receives operational parameters from a remote unit, allowing flow components associated with controlling a surgical tourniquet to be collocated with a surgical tourniquet in use, while allowing an operator of the tourniquet to operate the flow components from a remote location, such as at an anesthesiologists position, thus reducing the involvement of the surgical tourniquet operator from the surgical field.
