摘要： A needle assembly for treating tension pneumothorax includes an elongated needle disposed within an elongated catheter, and a housing for containing the needle and catheter. The needle is coupled to the housing through a length adjustment mechanism so that the needle and the catheter are configured to be deployed out of the distal end of the housing to a pre-determined length. The length adjustment mechanism may include an axial path in the wall of the housing, grooves extending off of the axial path, and a protruding arm coupled to the needle. The protruding arm of the needle is configured to extend through the axial path of the housing and be grasped by a user to deploy the needle and catheter out of the distal end of the housing. When the needle is deployed to a desired length, the user may lock the needle and catheter in place by positioning the protruding arm in the corresponding groove extending off of the axial path.

摘要： A method and device are provided for simultaneously or near-simultaneously diagnosing and treating tension pneumothorax and/or hemothorax. A 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.

摘要： An intercostal-pump based fluid management system, as described herein, comprises an intercostal pump that is, generally, a resiliently flexible bulb having an inlet and an outlet. The inlet is attached to a first tube that extends from the intercostal pump to a first area of a patient's body, for example, the patient's pleural cavity. The outlet is connected to a second tube that extends from the intercostal pump to a second area of a patient's body, for example, the patient's peritoneal cavity. In use, the intercostal pump is placed between a first rib and a second rib in a patient. The intercostal pump operates by being successively compressed and decompressed between the first and second ribs as the patient breaths.

摘要： A low-cost and simple-to-use system and method to facilitate a prophylactic pleural lavage protocol at the time of thoracostomy tube placement for traumatic hemothorax in order to reduce the need for secondary intervention for the management of retained hemothorax. The invention may be used in conjunction with existing chest tubes and be administered at the time of initial chest tube placement, and continued at the bedside (by a bedside nurse) over the duration of chest drainage, as necessary. The system includes an operator device that semi-automatically administers a pleural lavage protocol consisting of saline instillation, and suction to slow the clotting process, prevent “gelling” of blood, and maintain drainability.

摘要： A device, method, and system are provided for treating pleural effusion by administration of a chemical agent through a pleural catheter to achieve pleurodesis. A first embodiment includes a dual barreled syringe to deliver the sclerosing agent; one barrel includes a sclerosing agent, and the other barrel includes a flushing fluid. A kit of the invention comprises a plurality of syringe devices each preloaded with a sclerosing agent matched with a presumptive diagnosis regarding the etiology of the pleural effusion to be treated. A device of the invention includes a handheld, disposable, electronic delivery device with preloaded chambers holding selected medicaments and flushing fluid. Automatic delivery of medicaments is achieved in which a microcontroller of the device controls evacuation of the selected chambers by one or more actuators that communicate with the chambers.

摘要： A body cavity drainage device includes a drainage tube with a distal end configured for insertion into the body cavity of a patient, a fluid outlet at a proximal end of the drainage tube; and an activation apparatus coupled to the drainage tube between the proximal end of the drainage tube and the distal end of the drainage tube. The activation apparatus may be configured to alter a position of the distal end of the drainage tube in response to an input at a control device of the activation apparatus, and a first portion of the drainage tube extending from the activation apparatus toward the distal end may be at least substantially coaxial with a second portion of the drainage tube extending from the activation apparatus toward the proximal end. Methods relate to forming a body cavity drainage devices.

摘要： A chest drainage system including a collection device configured to receive fluid from the pleural cavity of a patient. A sensor is included to detect a pressure differential in the fluid. A display is configured to display a trend in occurrences of changes in pressure of the fluid over time in predetermined time increments based on a number of detections of pressure differentials that exceed a predetermined pressure differential during each of the predetermined time increments. The trend is correlative to the percentage of time that the patient is deemed to have an air leak in the pleural cavity in the predetermined time increments. The trend is derived from a ratio of the quantity of respiratory cycles of the patient for which the predetermined pressure differential is detected (QRCleak) in the predetermined time increments to the total quantity of respiratory cycles of the patient in respective predetermined time increments (QRCtotal).

摘要： A system includes a chest tube drainage system comprising a first chamber in fluid communication with a port connectable to a chest tube, a second chamber in fluid communication with a port connectable to a suction device, and a fluid seal connected to and disposed between the first chamber and the second chamber. The system also includes one or more gas sensors attached to the chest tube drainage system, the one or more gas sensors configured to detect at least one of gaseous carbon dioxide and gaseous oxygen, a controller connected to the one or more gas sensors, and at least one indicator coupled to the controller. The controller is configured to determine if a threshold level of carbon dioxide is exceeded, and to activate the at least one indicator if the threshold level of carbon dioxide is not exceeded.
