Abstract

Abstract A needle removal and storage device for removing needles from hypodermic needle/syringe assemblies and automatically receiving and safely storing removed needles within the device. The device includes a storage/containment member closed at one end and proportioned to receive used needles, and a top assembly at the open end of the storage/containment member which provides an opening to receive a needle and its hub portion. The top assembly is provided with a pair of grasping members mounted to generally opposite sides of the storage/containment member at its open end. The grasping members are adapted to receive the needle hub portion of a needle/syringe assembly and grasp the hub portion when squeezed together to permit removal of the needle from the syringe. The storage/containment member is generally flexible and resilient at its open end to permit the grasping members to be squeezed together so as to constrict the opening in the top assembly and grasp the needle hub at its ribbed portion for removal of the needle from the syringe, yet resiliently bias the grasping members away from each other after the grasping force is released to allow the needle to drop vertically into the storage/containment member, needle point first. The device further includes a closure member formed integrally with one of the grasping members via a living hinge-type connection. The closure member is adapted to releasably engage the other grasping member so as to hold the closure member securely closed over the open end of the storage/containment member when the device is not being used for removal of a needle.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 189 words
A method for removing the needle portion from a hypodermic needle/syringe assembly and safely storing the removed needle, comprising the steps of: opening a top closure member formed as part of the top assembly of a needle removal/storage device to expose a needle-receiving opening formed by grasping means which make up part of said top assembly by exerting a downward force on an oppositely projecting flange on said closure member by a finger of the same hand holding the device and simultaneously squeezing said top assembly to release releasable locking means formed between the top closure member and the rest of said top assembly; inserting the needle into said needle-receiving opening of said needle removal/storage device until its ribbed hub portion is adjacent said grasping means; exerting a squeezing force on said top assembly to cause constriction of said opening by forcing said grasping means towards each other to grasp the needle hub; rotating the needle/syringe assembly to separate the syringe from the needle; and releasing the squeezing force on the top assembly after the separation is complete to allow the needle to drop into said needle removal/storage device.
Claim 2
Independent Claim 189 words
A method for removing the needle portion from a hypodermic needle/syringe assembly and safely storing the removed needle, comprising the steps of: opening a top closure member formed as part of the top assembly of a needle removal/storage device to expose a needle-receiving opening formed by grasping means which make up part of said top assembly by exerting a downward force on an oppositely projecting flange on said closure member by a finger of the same hand holding the device and simultaneously squeezing said top assembly to release releasable locking means formed between the top closure member and the rest of said top assembly; inserting the needle into said needle-receiving opening of said needle removal/storage device until its ribbed hub portion is adjacent said grasping means; exerting a squeezing force on said top assembly to cause constriction of said opening by forcing said grasping means towards each other to grasp the needle hub; rotating the needle/syringe assembly to separate the syringe from the needle; and releasing the squeezing force on the top assembly after the separation is complete to allow the needle to drop into said needle removal/storage device.
Claim 3
Dependent Claim 48 words
A method according to claim 1, which further includes, after the removed needle is received and stored in said needle removal/storage device, the step of closing said top closure member by exerting a downward force on said closure member to cause said releasably locking means to become re-engaged.
