Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
A syringe destruction apparatus including a cam plate disposed in a casing and rotated by a motor rotating at a low speed, and a syringe needle shearing section and a barrel breaking section which are driven by the said cam plate, characterized in that the said syringe needle shearing section comprises a movable blade having a shaft part in sliding contact with one side of the said cam plates, a stationary blade paired with the movable blade and a guide part formed in the stationary blade, for guiding a syringe needle, and the said barrel breaking section comprises a movable blade having a shaft part in sliding contact with the other side of the said cam plate and a stationary blade paired with the said movable blade, thereby the movable blades in the said syringe needle shearing section and said barrel breaking section alternately carry out reciprocating rotation in association with the rotation of the said cam plate.
Claim 2
Dependent Claim
158 words
A syringe destruction apparatus including a cam plate disposed in a casing and rotated by a motor rotating at a low speed, and a syringe needle shearing section and a barrel breaking section which are driven by the said cam plate, characterized in that the said syringe needle shearing section comprises a movable blade having a shaft part in sliding contact with one side of the said cam plates, a stationary blade paired with the movable blade and a guide part formed in the stationary blade, for guiding a syringe needle, and the said barrel breaking section comprises a movable blade having a shaft part in sliding contact with the other side of the said cam plate and a stationary blade paired with the said movable blade, thereby the movable blades in the said syringe needle shearing section and said barrel breaking section alternately carry out reciprocating rotation in association with the rotation of the said cam plate.
Claim 3
Dependent Claim
37 words
A syringe destruction apparatus as set forth in claim 1, wherein the said stationary blades in the said syringe needle shearing section and the said barrel breaking section have cutting edges which are formed of circular holes.
Claim 4
Dependent Claim
37 words
A syringe destruction apparatus as set forth in claim 1 or 2, wherein the said stationary and movable blades in the said syringe needle shearing section and the said barrel breaking section are made of ceramic materials.
