Sheathing device for after use protection from a syringe needle

摘要

A syringe sheathing device is provided that shields a user from post-use needles that are still attached to a syringe. A cylindrical protective sheath fits over the syringe and may be extended irreversibly from a pre-use to a post-use position covering a used needle by sliding or telescoping the sheath past an easily dislodged pre-use position into the locked configuration. The pre-use configuration is easily assembled for delivery to a consumer.
