摘要:
A chest seal for treating an open pneumothorax that is low profile and thus unobtrusive so that the chest seal can be effectively maintained in position to seal a chest wound while allowing the pleural cavity to vent.
摘要:
A device is disclosed for the treatment of pneumothorax especially in neonates, which is an acute pathologic condition characterized by the extrapulmonic accumulation of air in the pleural space, causing restricted lung expansion and threatening to significantly worsen in a short period of time without intervention. Intervention in this case involves the simple one-hand introduction of a catheter-sheathed stylet through the chest wall as part of a compact device which contains a one-way valve outside the chest for the stat evacuation of the intrathoracic air or fluid. The device is capable of secure fixation to the chest wall until deemed no longer needed at which point it is quickly removable. The thoracic cavity is entered by a stylet which is surrounded by a catheter, the catheter lumen continuous with that of a lumenized dome which communicates with at least one upper port and one-way valving. One port is configured to allow Luer-Lok suction in the event of pleural effusion or hemothorax. The proposed device is small enough to allow easy one-hand application, does not require a scalpel incision, is economical by virtue of unified molding of major components, and can be readily secured to the chest wall. While the device was conceived with neonatal emergencies in mind, it can be scaled up in size for larger patients.
摘要:
A method for treating a pneumostoma by applying suction to the pneumostoma in order to remove solid or liquid discharge. A pneumostoma aspirator including a bulb or syringe is used to apply negative pressure to a tube which enters the pneumostoma. The pneumostoma aspirator may be used in conjunction with a pneumostoma management device. Alternatively, the pneumostoma aspirator may be used after the pneumostoma management device has been removed. The pneumostoma aspirator may also be used to introduce irrigation fluid into the pneumostoma and/or remove irrigation fluid and discharge from the pneumostoma.
摘要:
A pneumostoma management system includes a pneumostoma management device for maintaining the patency of a pneumostoma and a drug delivery device for pneumostoma care. The drug delivery device may be used to introduce therapeutic agents into the pneumostoma for direct treatment of the pneumostoma, treatment of the lung by way of collateral ventilation, and/or treatment of non-lung tissues by diffusion into the bloodstream. The drug delivery device includes a therapeutic agent dispenser for supplying a therapeutic agent and a propellant at positive pressure, an outlet and a connector for correctly positioning the outlet relative to a pneumostoma management device. The drug delivery device includes a self-centering and self-sealing connector for engaging the pneumostoma management device.
摘要:
A two-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease The first phase is a procedure to induce creation of a localized pleurodesis and is preferably performed as an outpatient procedure. The second phase is a procedure to introduce a surgical instrument into the lung via the pleurodesis to create the pneumostoma. An interval of about one of more days between the first and second phases allows the formation of a stable pleurodesis to prevent pneumothorax during the procedure.
摘要:
A pneumostoma management system includes a pneumostoma management device for maintaining the patency of a pneumostoma and a drug delivery device for pneumostoma care. The drug delivery device includes a therapeutic agent dispenser for supplying a therapeutic agent and a propellant at positive pressure, a tube for entering the pneumostoma and a limiting device for limiting the depth of insertion of the tube into a pneumostoma. The drug delivery device may be used to introduce therapeutic agents into the pneumostoma for direct treatment of the pneumostoma, treatment of the lung by way of collateral ventilation, and/or treatment of non-lung tissues by diffusion into the bloodstream.
摘要:
A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a pneumostoma vent having a tube which enters the pneumostoma to allow gases to escape the lung, a flange and a filter/valve to control flow of materials through the tube. The flange is a thin flexible patch which conforms and attaches to the chest of the patient. The flange secures the tube in position in the pneumostoma. The flange is formed in one piece with the tube.
摘要:
A method for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma. A pneumostoma management system includes a two-part pneumostoma management device and associated insertion and removal tools. The pneumostoma management device includes a pneumostoma vent and a chest mount for positioning and securing the vent into a pneumostoma. To use the system, the chest is first cleaned and the chest mount secured to the chest adjacent the pneumostoma. The pneumostoma vent is then inserted into the pneumostoma through an aperture in the chest mount until it is engaged and secured by a coupling of the chest mount. The pneumostoma vent may be replaced periodically such as daily. The chest mount may be changed less frequently such as weekly.

摘要:
A manually operable pump for the effective removal of fluids to include blood, blood clots, fluid, and air from a body cavity of a subject is provided. The manually operable pump is adapted to be connect to a range of fluid conduits and is equipped with one-way valves that effectively permit flow of fluid through the pump in only one direction. The sensitivity of the one-way valves is such that when properly positioned, fluid can flow through the valves and out of the pump without manual compression of the pump and with the aid of gravity power alone.
