Abstract
Abstract A medical needle removing and disposing system (10) comprises a box (12) having a plurality of compartments (14) therein, each for removing a needle assembly (58) from injection and/or blood drawing equipment (62) and for disposing of it. A compartment comprises first and second containers (16, 20) for defining first and second chambers (18, 22) with a needle gripper (24) positioned therebetween. The first container has a plastic, non-hardening, tacky, substance (44) therein. Injection and/or blood drawing equipment with a medical needle assembly mounted thereon can be manipulated to extend a shaft (60) of the needle assembly into the second chamber until a mounting tube (56) of the medical needle assembly is located at the needle assembly remover which grips the mounting tube so that the injection and/or blood drawing equipment can be rotated for unscrewing the mounting tube from the injection and/or blood drawing equipment. The medical needle assembly is left in the dispenser with the shaft buried in the tacky substance.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
346 words
A medical needle removing and disposing system for removing from injection and/or blood drawing equipment and disposing thereof a medical needle assembly having an elongated rigid shaft affixed on a mounting tube, said removing and disposing system comprising: a first container defining a first chamber, said first container having a first-chamber opening at one end thereof but being otherwise closed, said first chamber being of a size for receiving said shaft of said medical needle assembly extending therein through said first-chamber opening; a needle assembly remover means mounted at said first-chamber opening for gripping an outer surface of said mounting tube and thereby preventing said mounting tube from moving and for holding said needle assembly therein to dispose of said needle assembly; second container defining a second chamber aligned with, and communicating with said first chamber at said first-chamber opening, said second chamber having a second chamber opening opposite said first chamber opening of a size sufficiently large for receiving said mounting tube of said medical needle assembly as well as said injection and/or blood drawing equipment on which said mounting tube is mounted when said injection and/or blood drawing equipment is manipulated to extend said shaft through said second chamber into said first container; a one-way slidable cover having a racket mechanism thereon to allow said cover to close said second chamber opening, but to prevent said cover from being moved back to a position for uncovering said chamber opening; whereby, said injection and/or blood drawing equipment with a medical needle assembly mounted thereon can be manipulated to extend said shaft through said first-chamber opening into said first chamber until said mounting tube of said medical needle assembly is located at said needle assembly remover which engages said outer surface of said mounting tube, said injection and/or blood drawing equipment can then be manipulated relative to said needle assembly remover for detaching said mounting tube from said injection and/or blood drawing equipment to leave said medical needle assembly in said medical needle removing and disposing system, and said one-way slidable cover can then be closed.
Claim 2
Dependent Claim
346 words
A medical needle removing and disposing system for removing from injection and/or blood drawing equipment and disposing thereof a medical needle assembly having an elongated rigid shaft affixed on a mounting tube, said removing and disposing system comprising: a first container defining a first chamber, said first container having a first-chamber opening at one end thereof but being otherwise closed, said first chamber being of a size for receiving said shaft of said medical needle assembly extending therein through said first-chamber opening; a needle assembly remover means mounted at said first-chamber opening for gripping an outer surface of said mounting tube and thereby preventing said mounting tube from moving and for holding said needle assembly therein to dispose of said needle assembly; second container defining a second chamber aligned with, and communicating with said first chamber at said first-chamber opening, said second chamber having a second chamber opening opposite said first chamber opening of a size sufficiently large for receiving said mounting tube of said medical needle assembly as well as said injection and/or blood drawing equipment on which said mounting tube is mounted when said injection and/or blood drawing equipment is manipulated to extend said shaft through said second chamber into said first container; a one-way slidable cover having a racket mechanism thereon to allow said cover to close said second chamber opening, but to prevent said cover from being moved back to a position for uncovering said chamber opening; whereby, said injection and/or blood drawing equipment with a medical needle assembly mounted thereon can be manipulated to extend said shaft through said first-chamber opening into said first chamber until said mounting tube of said medical needle assembly is located at said needle assembly remover which engages said outer surface of said mounting tube, said injection and/or blood drawing equipment can then be manipulated relative to said needle assembly remover for detaching said mounting tube from said injection and/or blood drawing equipment to leave said medical needle assembly in said medical needle removing and disposing system, and said one-way slidable cover can then be closed.
Claim 3
Dependent Claim
41 words
