摘要

A catheter assembly (10) comprising a catheter (18), a needle (12) having a sharp distal tip (13), and a catheter hub (14) connected to the catheter (18) having the needle (12) passing therethrough, the catheter hub (14) including a valve (19) having a preformed opening (22) that selectively permits or blocks a flow of fluid through the catheter (18), a first inner diameter (32) that closes the valve (19), and a second inner diameter (30) larger than the first inner diameter (32), the second inner diameter (30) opening the valve (19), wherein the valve (19) is in an open position upon axially compressing the valve (19) into engagement with the second inner diameter (30) of the catheter hub (14), and the valve (19) is in a closed position upon releasing the valve (19) to engage the first inner diameter (32) of the catheter hub (14).
