A closed system suction catheter assembly has a suction catheter 20 extending between a suction control valve 30 and a patient end fitting 1 within a flexible envelope 23. The patient end fitting 1 has a flushing chamber 106 with an internal taper within which the patient end 22 of the catheter 20 is located when withdrawn. The flushing chamber 106 opens at its patient end via an opening 120 just large enough to allow passage of the suction catheter 20 and has a wiper seal 12 at the other end. The tip 22 of the suction catheter 20 is softer than the main part of the catheter to reduce trauma. |
