Abstract
The system (10) for collecting and disposing of contaminated waste products such as medical sharps and other medical wastes includes a housing (11) and its telescopic cover (9) which are fabricated of biodegradable and combustible material such as natural cellulose and non-natural cellulose. An absorbent biodegradable and combustible absorption package (30) or insert (35) can be placed in the bottom of the holding chamber (12) for absorbing any liquids emitted from the sharps and other wastes, and for enhancing the combustion of the medical sharps and other wastes when the housing is placed in a furnace. When the housing is burned it evolves no more than trace levels of sulfur or chlorine and yields substantially only biodegradable ash.
Claims34
A disposable combustible collector for receiving and incinerating used hypodermic needle syringes and other contaminated medical wastes comprising:
- a housing having a sidewall structure and end walls and defining a holding chamber with an opening in an end wall in communication with said holding chamber for the receipt of hypodermic needle syringes;
- at least said side wall structure of said housing being formed of liquid leak resistant, hypodermic needle puncture resistant, combustible material;
- a liquid absorption pack fabricated of liquid absorbent material contained in said housing for absorbing liquid emitted from the syringes placed in said housing;
- said absorption pack being of a size greater than the effective breadth of said opening so that the absorption pack cannot pass through said opening;
- and
- the side walls of said housing including indicia which identify the housing as containing used hypodermic needle syringes;
- whereby when the housing is placed in and upright attitude with the opening of the end wall facing upwardly, the liquid absorption pack rests on the lower end wall and used hypodermic needle syringes are moved through the opening and downwardly into the holding chamber, and liquids emitted from the syringes and which contact the liquid absorption pack are absorbed by the absorbent material and not leaked from the housing, and the housing and its contents are burned without opening the housing and the material of the collector burns and aids in the incineration of the syringes.
A disposable burnable collector for receiving and incinerating used hypodermic needle syringes and other forms of medical wastes comprising:
- a housing defining a holding chamber and defining an opening in communication with said holding chamber for the receipt of wastes,
- said housing comprising an inner primary container defining said holding chamber and an outer shipping container surrounding said inner primary container, said primary and shipping containers formed of liquid leak resistant and hypodermic needle puncture resistant burnable materials,
- liquid absorbent material positioned in said holding chamber in contact with the bottom of said holding chamber for absorbing liquid emitted from said wastes placed in said housing;
- whereby when wastes are placed in the holding chamber liquid emitted from the wastes and which contacts the absorbent material is absorbed by the absorbent material, and the collector and its contents are incinerated without opening the housing and the material of the housing burns.
A process of collecting and incinerating used hypodermic needle syringes and other medical wastes comprising:
- providing a housing formed of a combustible, hypodermic needle puncture resistant and liquid leak resistant material which defines a holding chamber sized and shaped to receive and contain hypodermic needle syringes;
- placing indicia On said housing which identifies the contents of the housing and the incineration destination to which the housing is to be delivered;
- placing an absorption pack formed of liquid absorbent material in the holding chamber;
- placing used hypodermic needle syringes in the holding chamber;
- absorbing liquid emitted from the syringes with the absorbent material of the absorption pack;
- delivering the housing and its contained syringes to the incineration destination;
- and
- incinerating the housing and its .contents in the incinerator at the incineration destination in accordance with the contents identified On the housing without removing the syringes from the holding chamber of the housing.
A disposable collector for receiving and incinerating at an incineration destination of medical wastes, including used hypodermic needle syringes needing incineration comprising:
- a housing defining a holding chamber and an opening in the upper portion of-said housing in communication with said holding chamber from outside said housing for the receipt of hypodermic needle syringes through said opening into said holding chamber, said housing being formed of materials that are combustible in a furnace environment and which are self supportive for retaining the shape of the housing during its intended use prior to incineration;
- indicia on said housing which identifies the contents of said housing and the incineration destination to which said housing is to be delivered;
- liquid absorptive material positioned in the lower portion of said housing for absorbing liquid emitted from the medical wastes placed in said holding chamber;
- means for retaining the hypodermic needles in said holding chamber;
- so that when liquid-bearing medical wastes are inserted through the opening and into said holding chamber, liquid emitted from the medical wastes and which liquid contacts the liquid absorption pack in the lower portion of said housing tends to become absorbed by the liquid absorptive material of the absorption pack and is retained in the absorption pack and does .not leak from the housing prior to the housing being burned and the housing and its contents are delivered to and burned in an incinerator at the incineration destination without opening the housing.
A disposable collector for receiving and incinerating at a remote incinerator of medical wastes including used hypodermic needle syringes needing incineration comprising:
- a housing defining a holding chamber, an opening in said housing in communication with said holding chamber from outside said housing for the receipt therethrough of medical wastes in said holding chamber;
- said housing comprising a double wall structure surrounding said holding chamber with an inner wall structure and an outer wall structure surrounding said inner wall structure, with said holding chamber defined by said inner wall structure;
- indicia carried by said housing for identifying the contents of said housing and the incineration destination to which said housing and its contents are to be delivered;
- liquid absorbent material positioned in said collector for absorbing liquid emitted from the medical wastes in said holding chamber and which liquid contacts the absorbent material;
- said opening including means for retaining the medical wastes in said holding chamber;
- whereby the medical wastes are inserted through the opening into the holding chamber of the inner wall structure and the double wall structure of the housing and its contents are delivered to an incinerator at the incineration destination where the housing and its contents are incinerated without removing the contents from the housing.
A method of collecting and incinerating medical wastes including used hypodermic needle syringes needing incineration, comprising:
- providing a hypodermic needle puncture resistant, liquid leak resistant housing fabricated at least in part of combustible material and defining a holding chamber for receiving and retaining medical wastes;
- applying indicia to said housing for identifying the contents of said housing and the incinerating destination of said housing;
- placing liquid absorbative material in the housing;
- placing used syringes in the holding chamber of the housing;
- absorbing with the absorptive material in the housing the liquid emitted from the used syringes and which liquid contacts the absorptive material;
- moving the housing and its contents to an incinerator at the incineration destination;
- placing the housing and its contents in an incinerator without opening the housing;
- and burning the housing and its contents in the incinerator in accordance with the indicia applied to the housing.
A disposable combustible collector for receiving and incinerating used hypodermic needle syringes and other contaminated medical wastes comprising:
- a primary container defining a holding chamber for containing the syringes;
- a flexible bag sized and shaped to receive and enclose said primary container, said bag comprising leak resistant liquid absorbent material;
- a shipping container sized and shaped to receive and enclose said primary container and said bag in which said primary container is received;
- indicia applied to said shipping container for identifying the contents of said shipping container and an incinerating destination of said collector and its contents;
- whereby used syringes are deposited in the holding chamber of the primary container, the primary container enclosed in the bag, and the primary container and its bag enclosed in the shipping container and transported to the incineration destination and incinerated without opening the shipping container in accordance with the indicia applied to the shipping container;
- and liquid emitted from said primary container is absorbed by and not leaked from the bag prior to the collector being incinerated.
