Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 174 words
A destruction device for a flanged needle head attached to a syringe, the device including a casing having a top wall provided with a needle head insertion opening, electric circuit means associated with the casing including a pair of electrodes within the casing under the needle head insertion opening, the electrodes being mutually located for receiving a needle portion of a needle head inserted in the opening therebetween whereby a short circuit is created between the electrodes for melting the needle portion, and the casing further including separator means for disconnecting the needle head with melted needle portion from the syringe, and collector means into which the separated needle head falls, wherein the separator means comprises an elongate guide track in the top wall of the casing extending from the needle head insertion opening, the guide track having downwardly inclined side walls for receiving the needle head flange thereunder after melting of the needle portion whereby sliding of the needle head along the guide track effects separation of the needle head from the syringe.
