Abstract

1,250,931. Catheter placement apparatus. BAXTER LABORATORIES Inc. 16 May, 1969 [18 June, 1968], No. 24960/69. Heading A5R. A catheter emplacement apparatus 10 comprises a hollow cannula 12 with an incising end 14 and a bore 15, within which is slidably mounted a catheter 18, a housing 20 disposed about the cannula away from the incising end, a tubular guard 24 arranged for movement in the housing axially of the cannula between a first position where the incising end is exposed and a second position where the incising end is covered, and means for fastening said guard in the second position. As described the guard 24 has axial grooves 42 which engage projections 30 on the housing. At the rear of the guard is a fastening section, 38 where, Fig. 5, one side of each slot is replaced by camming surfaces 44, 52 leading to sockets 54. In use cannula 12 is inserted into the organ, catheter 18 moved thro' the cannula into the organ and the cannula is withdrawn. Guard 24 is then pushed forward to cover the incising end and thus protect the catheter. When rear 36 of the guard engages projections 30 the guard is rotated relative to the housing and the projections snap into sockets 54 preventing the guard moving to uncover the incising end.
