ABSTRACT:
The invention relates to a self-locking syringe holder adapted for use with conventional hypodermic syringes and designed to prevent accidental puncturing of the medical attendant by an infected syringe needle. The holder has a hollow casing which receives the syringe barrel therein and which is provided with a pair of grooves within which locking tabs of a needle guard can move. Mounted within the casing is a compressible tension spring which continuously urges the needle guard into a fully extended position. To prevent misalignment of a needle guard with the casing, the needle guard is formed with a pair of longitudinal projections extending outwardly from an exterior surface of the needle guard and engageable with their respective cutout grooves formed in an end plate of a proximal end of the casing.
