Pneumothorax device

A pneumothorax device 2 comprises a valve 22 with a shutter 24 which obstructs the whole diameter of a linear passage 20 between a needle introducing port 16 and a catheter connecting port 18. The valve 22 may be a slip valve and the shutter 24 may be a flap or a resiliently deformable material which may be actuated by the force of insertion of a cannula, veress needle, syringe or guide wire, for example, onto the shutter 24 or by the pushing of a button or interface or by other known valve closure means. A second passage 50 extends from an intersection of the linear passage 20 to a discharge evacuation port 54. A one-way valve 8 and a gas and liquid reservoir 6 are in fluid communication with the discharge evacuation port 54.

A pleural manometry catheter

A pleural manometry catheter comprises two tubes and a pressure transducer. The first tube provides a first flow path from the pleural cavity to the pressure transducer. The second tube provides a second flow path from the pleural cavity such that fluid can be drained from the pleural cavity. The pressure transducer detects real-time changes in the fluid pressure of the first flow path, such that when in use, fluid is drained from the pleural cavity along the second tube, the sensor in communication with the first tube detects a concomitant drop in fluid pressure in the fluid in the first tube.
