Abstract

An apparatus and process for sterile disposal of used syringes is provided. The apparatus includes a heat conductive container for maintaining used syringes and a means for applying heat to the heat conductive container in an amount sufficient to melt the plastic of the syringes. The melted plastic can encapsulate the non-plastic portions of the syringe and form a molten mass. The molten mass is rendered sterile by the heat. The process for sterile disposal of used syringes in this manner is also provided.

Claims

1. A process for preparing syringes having at least a plastic portion and a needle for sterile disposal comprising:

providing a heat conductive container adapted to contain at least one syringe to be prepared for sterile disposal therein;

placing at least one syringe into the heat conductive container; and

applying heat to the heat conductive container in an amount sufficient to melt the at least one syringe so that the plastic of the plastic portion can encapsulate the needle of the syringe to form a molten mass and render the molten mass sterile.

2. The process of claim 1 wherein sufficient heat is applied to raise the temperature of the heat conductive container to between 380°

and 450°

F.

3. The process of claim 1 wherein the heat conductive container has an opening so that the at least one syringe can be placed therein and a lid which can be positioned on the container to close the opening and wherein the process further includes placing the at least one syringe into the heat conductive container through the opening and positioning the lid on the container to close the opening.

4. The process of claim 3 wherein the container further includes means for sealing the lid to the container and wherein the process further includes sealing the lid to the container using the sealing means.

5. The process of claim 4 wherein the sealing means is a meltable material provided between the container and the lid and wherein the process further includes melting the meltable material so as to fuse the container to the lid when heat is applied to the container.

6. The process of claim 4 wherein the sealing means is solder provided between the container and the lid and wherein the process further includes soldering the container to the lid by melting the solder when heat is applied to the container.

7. The process of claim 1 wherein the container further includes a heat sensitive strip which changes color at a specified predetermined temperature provided on the outside of the container and wherein the process further includes observing a change in color of the heat sensitive strip.

8. The process of claim 1 wherein the heat conductive container is contained in an oven assembly and wherein the oven assembly includes means for maintaining the temperature of the oven assembly at a present desired temperature and means for regulating the amount of time during which heat is applied and wherein the process further includes maintaining the temperature of the oven assembly at a present desired temperature and regulating the amount of time during which the preset desired temperature is maintained.

9. The process of claim 8 wherein the means for regulating the amount of time during which heat is applied is also useful for regulating the amount of time required to cool the heat conductive container to a temperature less than about 90°

C. and wherein the process further includes regulating the amount of time required to cool the heat conductive container to a temperature less than about 90°

C.

10. The process of claim 1 wherein the heat conductive container is contained in a barrel of an oven assembly wherein the barrel has a cover for covering the barrel and wherein the oven assembly further includes a safety interlock system which prevents application of heat to the heat conductive container if the cover is not on the barrel of the oven assembly and wherein the process further includes placing the barrel cover on the barrel of the oven assembly so that heat can be applied to the heat conductive container.
