  • the syringe disposal apparatus 30 constructed and arranged in accordance with the invention includes a heat conductive container 12 and a means for applying heat to the heat conductive container 12. As shown, the means for applying heat includes an oven assembly designated generally as 20.
  • the heat conductive container 12 is provided for containing disposable syringes 14 which are to be prepared for sterile disposal.
  • Heat conductive container 12 is constructed of any suitable heat conductive material such as, for example, a metal, metal alloy, glass or ceramic and certain high temperature resistant plastics. Suitable heat conductive metals include, but are not limited to, aluminum, copper and the like.
  • Container 12 can be any suitable size or shape for holding disposable syringes 14. While disposable syringes 14 are available in numerous different sizes and styles, container 12 may be provided for accommodating one or more predetermined styles in a particular manner or may be generally large enough to accommodate any syringe. It is generally preferable to provide a container of a size and configuration that permits the needle and plastic syringe assemblies 14 to stand with the needle pointing downward, generally in the way that pencils stand in a pencil holder. It is contemplated that the containers can be of a size and configuration that permits multiple containers to be stacked prior to use.
  • Container 12 has at least one opening 16 which is used to place disposable syringes 14 into container 12.
  • a lid 18 is provided to cover opening 16.
  • Lid 18 can be any appropriate size or shape suitable for sealing opening 16, either permanently or temporarily.
  • the lid 18 can be of any suitable type including, but not limited to, self-sealing lids, pop-on lids, screw on lids, twist- on lids, "child” resistant or tamper-resistant lids, and the like.
  • a fusable material such as a solder 19 can be provided between the container 12 and the lid 18 so that when heat is applied to the container 12 the fusable material fuses the lid to the container 12.
  • lid 18 is of a permanent or temporary type is at least partially a function of whether the entire container 12 and lid 18 having melted disposable syringes 15 therein is to be disposed of or whether the molten mass 15 of disposable syringes 14 is to be removed from container 12 prior to disposal. Obviously, if the entire container 12, lid 18 and contents 15 are to be disposed of as a unit there is no difficulty in permanently sealing lid 18 to container 12 after an appropriate number of disposable syringes 14 are placed in container 12. On the other hand, if the molten mass 15 of disposable syringes 14 is to be removed from container 12 after being subjected to heat treatment, then lid 18 must be removable from container 12 and permanent sealing is not appropriate.
  • the entire container 12 with lid 18 and contents 15 is disposed of after heat treatment. Accordingly, it is desireable for lid 18 to be permanently sealed to container 12 either prior to or during the heat treatment. Additionally, container 12 must be removable from apparatus 10 and replaceable with a new container 12. In carrying out this embodiment of the invention, it is a particularly advantageous feature if the top 17 of lid 18 and the bottom 13 of container 12 are cooperatively beveled so that used containers 12 with lids 18 secured thereto can be stacked for storage purposes. Any appropriate means for beveling lids 18 and container 12 so that multiple container 12 and lid 18 combinations can be stacked for storage is within the contemplation of the invention.
  • Container 12 is also preferably provided with a heat sensitive strip or indicator 40.
  • the heat sensitive strip 40 is provided on the outside of container 12 or lid 18 so that it can be viewed when the container 12 is removed from the oven assembly 20 and is of a type that changes color at a specified predetermined temperature.
  • the specified predetermined, temperature should be the temperature that the heat conductive container 12 must achieve in order to melt the syringes 14 and is generally above 380°F. Accordingly, a user can determine at a glance whether the specified temperature has, in fact, been achieved during the heating cycle and therefore, whether the container 12 and its contents 15 can be disposed of as sterile waste.
  • a one way opening for inserting syringes 14 into container 12 can be provided either as part of lid 18 or as a separate underlid which will ultimately be covered by lid 18. Such one way openings would provide an additional safety feature.
  • means for snipping the needle from the syringe prior to disposing of both the needle and plastic in the container 12 might also be useful in the apparatus disclosed.
  • the means for applying heat to the heat conductive container may be any form of oven assembly, heating element or heater which meets the requirement of being capable of applying heat in an amount sufficient to melt the at least one syringe in the heat conductive container 12 to cause the melted plastic of the syringe 14 to encapsulate the needle as a melted mass 15 and render the melted mass 15 sterile.
  • the means for applying heat should achieve a temperature between about 380° and 450°F. At temperatures less than about 380°F, the plastic of the syringes 14 is not melted and the plastic does not encapsulate the needle.
  • neoprene rubber which is often provided on the end of the plunger of the syringe 14, starts to burn and give off noxious fumes. Furthermore, it is not desirable to apply heat at temperatures greater than those necessary to accomplish the desired result as this results in decreased energy efficiency.
  • the heat is to be applied for an amount of time sufficient to render the molten mass sterile in addition to melting the plastic portion of the syringe so as to encapsulate the needle.
  • the entire heat application cycle is about one hour. This includes about one half hour for the heat conductive container to be brought to the desired temperature and about one half hour for the container to be maintained at the temperature achieved. It has been found that maintenance of the temperature achieved for less than one half hour will not permit the molten mass to be rendered sterile.
  • the means for applying heat preferably includes an oven assembly designated generally as 20.
  • Oven assembly 20 has a barrel 21 with a cover 32.
  • the barrel 21 is of a suitable size for accomodating the heat conductive container 12 therein.
  • a heater 30, which can be of any appropriate type, provides heat to barrel 21.
  • barrel 21 conducts heat to the heat conductive container 12 so that syringes 14 can be melted and the molten mass rendered sterile.
  • Oven assembly 20 also preferably includes a temperature sensor 22 mounted on the wall of the oven assembly 20.
  • the temperature sensor 22 is a thermocouple which senses the temperature of oven assembly 20 and feeds the information to a temperature controller 24.
  • the temperature sensor 22 also preferably includes a shut-off switch 23 which inactivates the entire system if the temperature of the oven assembly 20 climbs above a defined maximum temperature of generally about 450°F.
  • the shut off switch 23 is normally closed and opens at about the defined maximum temperature.
  • the temperature controller 24 is a circuit designed to receive a signal from the temperature sensor 22.
  • the controller 24 is preset to a desired temperature by setting the level within the controller.
  • the signal received from the temperature sensor 22 is compared to the preset level defined by the controller 24. If the actual temperature of the oven assembly 20 is either above or below the set point of the temperature controller 24, the controller 24 lowers or raises the amount of power supplied to the heater 30 until the controller 24 no longer detects a difference between the two signals.
  • the temperature of the oven assembly 20 is accurately maintained throughout the operating cycle by this feedback process.
  • Oven assembly 20 also preferably includes a timer 26 so that the length of the period of time for which heat is to be applied can be regulated.
  • the timer 26 generally includes a circuit that closes or opens switch contacts for a specified time interval in response to a signal, which is preferably an electrical signal.
  • the timer 26 is preset to a specified time interval prior to initiation of the heat application and syringe destruction cycle and prevents oven assembly 20 from being opened during this preset time interval.
  • the preset time interval whould be long enough to include the entire heat application and syringe destruction cycle as well as a cooling period during which the container 12 and oven assembly 20 have an opportunity to cool down to a temperature at which they will no longer be harmful to an operator, generally about 90°.
  • circuit board 60 can be positioned within housing 29 adjacent a wall 62 as shown in FIG. 4. Circuit board 60 can also then be used to control appropriate information readouts on the outside of housing 29 as discussed in more detail below.
  • Oven assembly 20 preferably also includes a safety interlock system of the type shown in FIG. 3.
  • the safety interlock system is a system of electrical components within the syringe destruction apparatus 10 that protects the operator from harm.
  • the safety interlock system prevents initiation of a heating cycle unless the cover 32 of oven assembly 20 is in place, prevents removal of cover 32 when the temperature of the oven assembly 20 is above a predetermined maximum safe temperature of generally about 90°F, and removes primary AC power from the entire system in the event of a temperature rise above a predetermined maximum temperature of generally about 450°F.
  • Cover detecting switch 34 forms part of the safety interlock system and prevents initiation of a heating cycle unless the cover 32 of oven assembly 20 is in place.
  • Cover detecting switch is preferably a normally open, lever actuated type contact switch used to detect the presence of the oven assembly cover 32.
  • the lever 35 is spring loaded to exert force upward against the cover 32. However, pressing the cover 32 downward overcomes the spring force and causes the lever to close the switch contact when cover 32 is positioned on barrel 21 of oven assembly 20. The heating cycle cannot be initiated until cover detecting switch 34 is closed.
  • On switch 36 is also a normally open momentary contact device that is closed by the action of an operator to begin a heating cycle. "On" switch 36 must remain closed in order for the heating cycle to continue and therefore, once the heating cycle has been initiated control of "On" switch 36 is governed by timer 26.
  • An electromagnetic solenoid 38 includes a coil of wire wrapped around a hollow cylinder.
  • a ferrous metal rod 46 is positioned within the hollow cylinder and is spring lchaded so as to be maintained within the body of the.cylinder until the coil of wire is energized.
  • a magnetic field of opposite polarity to the coil is produced in the rod 46. This causes the rod 46 to be displaced from the body of the solenoid 38.
  • the rod 46 is displaced linearly for a short distance of generally about one inch.
  • the solenoid 38 can only be actuated for removal or insertion of the heat conductive syringe container 12 when switch 62 and thermostat contact 64 are closed.
  • the thermostat contace 64 is always closed then the oven assembly 20 is at a temperature less than some predetermined specified temperature, generally less than about 90°F.
  • Switch 62 is a single pole single throw contact switch that is actuated by the operator into a closed state amd remains in the closed state for the time necessary to insert or remove the heat conductive container 12.
  • the circuit is completed only when the thermostat contact 64 are closed at less than the preset predetermined temperature of generally less than about 90°F.
  • the thermostat contacts 23 remain closed at a predetermined maximum temperature of generally less than about 450°F. If a condition occurs that causes the temperature of oven assembly 20 to rise above that predetermined maximum temperature of generally about 450°F the contact opens and interrupts the main AC power supply to the entire system.
  • the barrel 21 of the oven assembly 20 is insulated with a suitable insulating material 48 to prevent destruction of the other elements of the system.
  • One suitable insulating material 48 is a flexible ceramic type material having the appearance of cotton. The material may generally have a thickness of between about 1/2 and 3/4 inches, preferably about 1/2 inch.
  • the entire oven assembly 20 is preferably incorporated in a suitable housing or enclosure 29.
  • Enclosure 29 is preferably constructed of stainless steel and houses the entire system in such a way as to provide insulation to the temperature controller 24, timer 25, safety interlock and other components the might otherwise be damaged by exposure to the high temperatures generated by the oven assembly 20.
  • enclosure 28 also preferably employs appropriate venting and/or a fan or fans to create preferential air flow away from sensistive system components.
  • Appropriate information readouts can b e provided on the exterior of enclosure 29 for the benefit of an operator.
  • Such readouts preferably include one or more of the temperature of the oven assembly and/or the maximum temperature to which the heating cycle has been set 50, the cycle time and/or the amount of time remaining in the cycle wherein the cycle time is defined as either the heating cycle or the heating and cooling cycle 52, an emergency shut off switch 54 and a switch for initiating operation of the apparatus, an "on" switch 56.
  • a light or other means for indicating that the apparatus is in operation can also be used.
  • disposable syringes 14 are placed within heat conductive container 12 and lid 18 is fitted on container 12 to cover opening 16.

  • a timer 26 is set to the length of time for which the heat application cycle is to continue and the temperature setting is set to the maximum temperature which is to be achieved and maintained during the heating cycle.
  • Switches 36 and 62 are closed by initiating the heating cycle from a switch on the exterior of enclosure 29.
  • Depressing the "on" switch 56 activates the heater 30 and causes the oven assembly 20 to be heated to the preset maximum temperature.
  • a temperature sensor 22 provided on the oven assembly 20 continuously feeds a signal associated with the temperature of the oven assembly 20 to a temperature controller 24. So long as the temperature determined by the temperature sensor 22 is less than the predetermined preset temperature defined by the temperature controller 24, additional energy continues to be put into the system.
  • the temperature controller 24 maintains the oven assembly 20 at that temperature fot a predetermined period of time as set by the timer 26.
