Sharps disposal system

Abstract

A disposal system particularly adapted for hospital use comprising two portions. The first portion is composed of a hollow, outer enclosure adapted for wall-mounting and including an elongated slot inlet at the top with a barrier adjacent the slot for restricting access to the interior of the enclosure. The enclosure also includes a hinged access door for permitting insertion of the second portion of the invention, an inner container, therewithin. The inner container includes an inlet formed in registration with the slot when installed within the enclosure. The inner container includes a pivotal closure which may be locked in place when full in order to prevent access to the contents of the container.

       8. A disposal system according to claim 6 in which said inner container includes transparent windows in opposite sides thereof, and said sensing means includes a visual detector adjacent said windows. 
     
     
       9. A disposal system according to claim 8 in which said visual detector comprises a photoelectric detector mounted in said outer enclosure adjacent one said window and a photoelectric transmitter mounted in said outer enclosure adjacent the other of said windows and in registration with said photoelectric detector. 
     
     
       10. A disposal system according to claim 1 including means permitting removal of said inner container from said outer enclosure. 
     
     
       11. A disposal system according to claim 10 in which said removal means comprises an access door in said outer enclosure. 
     
     
       12. A disposal system according to claim 1 in which said barrier means includes a raised shelf at one longitudinal side of said slot, and said constriction comprises a cowl extending from the opposite longitudinal side of said slot, said shelf and cowl defining therebetween a limited opening to said outer enclosure. 
     
     
       13. A disposal system comprising a. a hollow, outer enclosure,   b. a slot in the top of said outer enclosure for permitting access to the interior of said outer enclosure,   c. barrier means disposed adjacent said slot for restricting access to the interior of said outer enclosure, said barrier means including a cowl extending above and over said slot,   d. an inner container disposed within said outer enclosure, said inner container having an inlet in alignment with and no larger in dimension than said slot, said inlet extending into said slot, and   e. means permitting removal of said inner container from said outer enclosure.   
     
     
       14. A disposal system according to claim 13 in which said inlet includes a hood on said inner container disposed within and generally conforming to said cowl. 
     
     
       15. A disposal system according to claim 13 including a pivotal closure disposed within said inlet, said inner container including means for locking said closure to prevent access to the interior of said inner container. 
     
     
       16. A disposal system according to claim 13 in which said removal means comprises an access door in said outer enclosure. 
     
     
       17. A disposal system according to claim 13 in which said barrier means includes a raised shelf at one longitudinal side of said slot, and said cowl extends from the opposite longitudinal side of said slot, said shelf and said cowl defining therebetween a limited opening to said outer enclosure. 
     
     
       18. A disposal system comprising a. a hollow, outer enclosure,   b. a slot in the top of said outer enclosure for permitting access to the interior of said outer enclosure,   c. barrier means disposed adjacent said slot for restricting access to the interior of said outer enclosure, said barrier means including a cowl extending above and over said slot,   d. an inner container disposed within said outer enclosure, said inner container having an inlet in alignment with said slot, said inlet including a hood disposed within and generally conforming to said cowl, and   e. means permitting removal of said inner container from said outer enclosure.   
     
     
       19. A disposal system according to claim 19 including a pivotal closure disposed within said inlet, said hood including means for locking said closure to prevent access to the interior of said inner container. 
     
     
       20. A disposal system according to claim 19 in which said locking means comprises a plurality of catches within said hood, each catch including stop means engaging said closure when said closure is pivoted in one direction past said stop means into the interior of said hood, said stop means preventing pivoting of said closure in the opposite direction.
