Abstract
A catheter placement unit comprises an introducing needle (2) having a pointed tip (6) for introducing a catheter (4) into a desired position in a patient's body, a needle hub (3) for mounting the needle (2) so that the needle extends through an axial bore in the catheter (4) during introduction of the catheter into the patient's body and so that the needle can subsequently be withdrawn from the catheter bore leaving the catheter in position in the patient's body, and a needle tip protector (10) on the needle for shielding the needle tip (6) when the needle has been withdrawn from the catheter bore. The needle tip protector (10) includes a guard element (16) which is held against a resilient bias in a cocked position to one side of the catheter (4) while the catheter is introduced into the patient's body and which, on subsequent withdrawal of the needle (2) from the catheter bore, is moved laterally by resilient action from the cocked position into a guard position in which it shields the needle tip (6). Thus the protector (10) reliably guards against needle stick injuries during withdrawal and subsequent disposal of the needle.
