Method and device for simultaneously documenting and treating tension pneumothorax and/or hemothorax
ActiveUS20140046303A1Reduce the possibilityReduce manufacturing costDiagnosticsSurgical needlesPleural cavityAtmospheric pressure
A method and device are provided for simultaneously or near-simultaneously diagnosing and treating tension pneumothorax and / or hemothoraxA Veress-type needle portion includes a hollow needle for puncturing the chest wall over a blunt hollow probe biased by one or more springs to extend distally into the pleural cavity. Openings in the blunt hollow probe connect via a pathway to an automatic check valve, which permits the flow of air and / or fluid only in a proximal direction. Pressure from within the pleural cavity is transmitted to the interior surface of a pressure documenter. If pressure greater than atmospheric pressure is present in the pleural cavity, the pressure documenter will be automatically urged proximally to simultaneously allow air and / or fluid to escape from the pleural space through the device, thus treating the tension pneumothorax and / or hemothorax, as well as providing a stable indicator to positively document the diagnosis of increased pressure.
