Abstract
A disposable thermoplastic hypodermic syringe having a hollow metallic needle and thermoplastic body portions at least part of which are formed of temperature calibrated thermoplastic having a full flow liquefaction temperature corresponding to point on the time-death curve for microbial life at which the most resistant spore forms are killed within the time the thermoplastic can be liquefied and resolidified. Heat resistant indicia can be applied to the syringe in a manner to reappear on the solidified thermoplastic mass.
Claims4
A thermal processor for melting and solidifying materials including thermoplastic in conjunction with medical waste, said processor comprising:
- a housing having an upper end and a lower end;
- a controllable heat source adjacent to the lower end of the housing;
- a heat resistant container removably mounted in the housing and adapted to receive the materials for processing, said container having sides, an upper end and a lower end;
- a controllable heat source disposed below the container to apply heat to the lower end thereof;
- and
- a baffle means disposed within the housing to engage the sides of the container adjacent its lower end to define a hot chamber between the baffle and the heat source and a cool chamber above the baffle.
