摘要:
A method and a microprocessor controlled device for use in medical evaluation of the pulmonary system. The method and device incorporate two different non invasive evaluative techniques. Passive auscultation provides indicators of lung condition. Active auscultation, a different evaluative technique, provides information or indications generally not available or provided from passive auscultation. Combining the information from both techniques greatly improves the ability to provide effective medical treatment.
摘要:
A device for detecting and counting coughing events is provided. In one embodiment a sensor for sensing and transducing low frequency and high frequency mechanical vibrations, sends signals to a coincidence detector that determines if high and low signals coincide. In another embodiment, ultrasonic energy is introduced to the trachea and if Doppler shift in frequency is detected, association is made to a coughing event. In another embodiment a change in the impedance of the neck is considered associated with coughing event if correlated over time with a specific mechanical frequency sensed.
摘要:
Disclosed is a device for exsanguinating a portion of an extremity, the device comprising a torus having a variable circumferential diameter, the torus configured to encircle an extremity portion and apply exsanguination pressure thereto, and a transducer operatively associated with the torus, the transducer, while the torus is encircling the extremity portion, being configured to control at least one of a diameter of the variable circumferential diameter, a tension in the torus and a pressure applied by the torus.
摘要:
A timer for tourniquet, adapted for application in a surgery, emergency or military situations to stop arterial blood loss in an injured limb, which is optionally activated by use of the tourniquet and/or optionally provided in association with a monitor for a plurality of tourniquets.
摘要:
A mechanized tourniquet adapted for application in a surgery, emergency or military situation to stop arterial blood loss in an injured limb, which is optionally activated by a user or automatically by detecting therein the free tip of its pressure-applying band. The tourniquet and its electromechanical tension device are automatically controlled by means of the band tension controlling mechanism and a timer initialized by a safety signal.
摘要:
A method and apparatus for determining the air pressure in a lung comprises making a determination of the velocity of sound in the lung and estimating the pressure within the lung based on the determined velocity. The method also includes determining a difference in phase for sound between two positions with respect to the lung.
摘要:
Disclosed is a device for exsanguinating a portion of an extremity. The device comprises an elastic torus configured to ensanguine a limb when surrounding an extremity and pulled at a first linear rate in a first direction; and at least one elongate attachment element mechanically coupled to the torus to convey pulling force from the handle to the torus, wherein the a length of the elongate attachment element between the handle and the torus elongates at a different rate than the first rate, during the pulling.
摘要:
A method for assessing a broncho-dynamic response in a subject includes introducing a sound signal having known characteristics into the airway of a subject, detecting one or more responsive sound signals at one or more locations on the thorax, administering a broncho-effector to the subject, and determining the subject's response to the broncho-effector by monitoring the one or more responsive sound signals before and after administering the broncho-effector. Changes in the responsive sound signal characteristics indicate the subject's broncho-dynamic response to the broncho-effector. Apparatus for assessing broncho-dynamic response in a subject is also provided.
