Lockable safety shield for hypodermic syringe |
摘要 |
A lockable safety shield is provided for a hypodermic syringe. The safety shield is mounted over the syringe barrel and can be telescoped into a position for protectively guarding a sharp point on the needle cannula. Oppositely facing stop surfaces on the syringe barrel and the safety shield prevent complete telescoped removal of the safety shield from the syringe barrel. A deflectable wall on the syringe barrel snaps into engagement with locking teeth on the safety shield when the safety shield has been telescoped into a position for guarding the needle cannula point to prevent exposure of the used needle cannula.
