Abstract:
1. Apparatus for providing a fluid passageway into an individual, the apparatus comprising: a port in fluid communication with the atmosphere; a catheter having a proximal end arranged to be inserted into the body of an individual and having a distal end; a one-way valve; and a fluid passage switch, in fluid communication with the port, catheter and one-way valve, wherein: the one-way valve is arranged to only permit the aspiration of fluid out of the apparatus; the fluid passage switch and the port are arranged to receive a needle therein; and the fluid passage switch is reversibly movable between a first position in which the distal end of the catheter is in fluid communication with the port and in which the port and the catheter are axially aligned, such that whenever the fluid passage switch is in the first position a needle can be introduced into the catheter via the port and fluid passage switch, and a second position in which the distal end of the catheter is in fluid communication with the one-way valve, such that whenever the fluid passage switch is in the second position aspiration of fluid through the catheter and subsequently the one-way valve is permitted.
