A chest drainage system securing apparatus for securing and maintaining chest drainage systems in position following placement into a human or animal patient and preventing movement or unplanned removal thereof in response to the application of significant forces in any direction thereto, be they longitudinal, torsional/rotational or bending. The securement system includes retention devices secured to a chest tube which interact with an adhesive pad releasably attached to a patient to ensure proper positioning of the chest tube. The adhesive pad includes one or more Heimlich-type valves for sealing sucking chest wounds and for sealing an incision formed in a patients skin and chest for the placement and insertion of a chest tube.

Some embodiments of the present disclosure provide a pneumothorax detection method performed by a computing device. The method may comprise obtaining predicted pneumothorax information, predicted tube information, and a predicted spinal baseline with respect to an input image from a trained pneumothorax prediction model; determining at least one pneumothorax representative position for the predicted pneumothorax information and at least one tube representative position for the predicted tube information, in a prediction image in which the predicted pneumothorax information and the predicted tube information are displayed; dividing the prediction image into a first region and a second region by the predicted spinal baseline; and determining a region in which the at least one pneumothorax representative position and the at least one tube representative position exist among the first region and the second region.

A system for treatment of an open wound in a chest of a patient is disclosed. The system includes a seal membrane configured to adhere to the chest and having an air passage. The system also includes a mechanism removably coupled to the seal membrane over the air passage. The mechanism is configured to allow air to pass through the mechanism in a first direction and not to pass in a second direction opposite the first direction.

An indwelling pleural catheter system comprises an indwelling catheter device (2) comprising a catheter tube (7) with a fenestrated distal end (7A) configured to reside in the pleural cavity of a subject and a connection hub (10) fluidically coupled to a proximal end (7B) of the catheter tube, a skin anchoring member (3) to anchor the connection hub (10) to the skin of the subject, and optionally a detachable ambulatory suction module (4) configured for detachable attachment to the connection hub (10). The suction module (4) comprises a fluid inlet (19) configured for fluidic coupling to the catheter tube (7) through the connection hub (10) and a fluid outlet (20) configured for detachable fluidic coupling to a pleural fluid drainage system (5) to drain pleural fluid through the detachable ambulatory suction module. The detachable ambulatory suction module is configured to exert a negative pressure in the catheter tube upon detachment of the pleural fluid drainage system from the suction module. Treatment of pleural effusion using the system of the invention is described. An indwelling catheter system for draining fluid from the peritoneal cavity, and methods of treating ascites, is also described.

A surgical system for use in establishing and maintaining an opening to an anatomical space of a body, the system comprising an obturator assembly having a cutting portion at a distal end and a cannula, the cannula being detachably coupled to the cutting portion and deployable into the anatomical space of a patient, the cannula comprises a locking portion, and a lengthwise extendable body; a valve assembly comprising a passage for receiving the cannula, a first end for coupling to a fluid extraction device and a second end for placement external and adjacent the anatomical space; a base comprising a plate for placement on a patient external and adjacent the anatomical space, the plate has an aperture configured for receiving the obturator assembly and coupling means located about the aperture for coupling with the valve assembly; and wherein, in use, the locking portion of the cannula is configured to be retained in the valve assembly with the extendable body extended into the anatomical space to facilitate a path for fluid extraction, and wherein the cannula comprises means for retaining the cannula in its extended state.
