Abstract
A catheter inserter has an inserter housing with a flat base and a cannula housing disposed within the inserter housing with a cannula extending generally parallel to the inserter housing longitudinal axis. Stop means are disposed at each end of the inserter housing. locking means on the cannula housing selectively engage the stop means to lock the cannula housing in a first disposition in which the cannula extends outwardly from the inserter housing and in a second disposition in which the cannula is retracted within said inserter housing. The cannula housing has a passage in fluid communication with the cannula which, together with means on the inserter housing and cannula housing, permit the external viewing of blood passing into the fluid passage from the cannula.
Claims6
A catheter inserter comprising:
- an inserter housing of parti-cylindrical configuration having a flat base which is generally parallel to the longitudinal axis of the inserter housing;
- a cannula;
- a cannula housing disposed within the inserter housing and longitudinally slidable therewithin, said cannula housing having a main body portion of a cross-sectional configuration which is generally complementary with the inserter housing cross-sectional configuration;
- said cannula housing including hub means for fixing said cannula to said cannula housing main body so as to extend generally parallel to the inserter housing longitudinal axis;
- first stop means disposed at said first end of said inserter housing;
- locking means formed on said cannula housing so as to be selectively engageable with said first stop means to lock said cannula housing in a first disposition in which the cannula extends outwardly from the inserter housing at a first end of said inserter housing;
- and
- second stop means formed on said inserter housing remote from said first stop means and selectively engageable with said locking means to lock said cannula housing in a second disposition in which said cannula is retracted within said inserter housing.
A catheter inserter as in any one of the preceding claims, and in which the cannula housing has a passage formed therein so as to be in fluid communication with the cannula;
- and
- means on said inserter housing and said cannula housing to permit the external viewing of blood passing into the fluid passage from the cannula.
