Abstract
A syringe assembly includes a housing having a cavity for receiving an associated fluid. A plunger assembly includes a piston and a shaft connected thereto for selectively dispensing the associated fluid from the housing through a dispensing opening. A container receives the housing and plunger assembly. The container has a first opening at a first end that selectively receives a cap thereon and covers the dispensing opening when the cap is secured to the container, and second opening at a second end that opens to the plunger assembly shaft.
Claims14
A syringe assembly comprising:
- a housing having a cavity for receiving an associated fluid therein and having a dispensing opening communicating with the cavity through which the associated fluid is selectively dispensed;
- a plunger assembly operatively connected to the housing and including a piston and a shaft connected to the piston for selectively dispensing the associated fluid from the housing dispensing opening;
- and
- a container that receives the housing and plunger assembly, the container having a first opening at a first end that selectively receives a removable cap thereon and covers the dispensing opening when the cap is secured to the container and allowing access to the dispensing opening when the cap is removed from the container, and second opening at a second end that opens to the plunger assembly shaft, wherein the shaft is dimensioned so that the shaft does not extend through the container second opening, wherein the shaft includes a stop member that selectively engages a surface of the container adjacent the second opening to limit movement of the shaft through the container second opening.
