Tracheostomy tube obturator for introducing medical tube through an opening formed in the skin or other tissue

摘要

The obturator (40) has a patient end nose (47) protruding from the patient end (10') of the tube (1'). A passage for a guide wire (3') extends through the nose of the obturator at an angle to its axis (50'). The aperture (49) through which the passage (28') opens at the patient end of the obturator lies on a plane (46) extending at right angles to the passage and inclined away from the normal to the axis of the nose by about 8 deg .
