DISPOSABLE SYRINGE WITH BUILT-IN CARPULE |
摘要 |
A disposable syringe includes a barrel, a seat member held by a grip member in the barrel such that a needle cannula extends through the seat member, a carpule configured to be fitted in a rear compartment of the barrel, and having front and rear seal members to confine a sealed chamber communicated with the needle cannula for holding liquid medicament, and a plunger operable to move the rear seal member forwardly to expel the liquid medicament through the needle cannula so as to bring the carpule in a used-up position, and to further move the front seal member from the used-up position so as to remove the grip member from the seat member to thereby bring the seat member to the disengaging position. A biasing member is disposed to bias the seat member together with the carpule rearwardly so as to retract the used needle cannula into the barrel.
