Abstract
A method of destroying and storing a cannula adapted to contact bodily fluids. According to the method, a cannula having at least one sharp point is disposed in an operative relationship with a reel which is fitted in a housing, A portion of the cannula extends exteriorly of the housing and is slidably disposed within an aperture in the housing. A portion of the cannula that is disposed within the housing engages the reel when it is turned and bends the cannula to destroy it and simultaneously commences drawing the cannula into the housing through the aperture to store it. The turning is continued until the point is fully withdrawn into the housing. When fully withdrawn, the point(s) of the cannula snap against the inside of the housing and provide a sensory indication that they are fully withdrawn.
Claims15
A method of rendering harmless a cannula used for injections, a first portion of said cannula being disposed within a housing and a second portion extending outwardly therefrom and terminating in an end, said method comprising the steps of:
- disposing part of said first portion of said cannula in a rotatable reel;
- turning said reel about an axis to draw said second portion of said cannula into said housing to destroy said cannula and store it within said housing.
A method of destroying and storing a cannula adapted to contact bodily fluids, said method comprising:
- disposing a cannula having two sharp points at the ends thereof in a fixed relationship within a storage means, said storage means being disposed within a housing, a portion of said cannula extending exteriorly of said housing through apertures formed in said housing, said points being disposed outside of said housing and said cannula being slidably arranged within said apertures;
- engaging portions of the cannula with said storage means and bending said cannula and simultaneously commencing drawing said cannula into said housing through said apertures;
- continuing said engagement until said points are fully withdrawn into said housing whereby to destroy said cannula and store it within said housing.
A method of using, destroying and safely storing a cannula having at least one sharp point, said method including:
- disposing a part of a first portion of said cannula in a reel, said reel being disposed in a housing with a second portion of said cannula and said sharp point being disposed outside of said housing;
- using said cannula and after use, engaging a part of said first portion of said cannula with said reel;
- turning said reel and simultaneously deforming said cannula and wrapping it around said reel whereby to draw said sharp point into said housing to destroy and store it.
A method of destroying and storing a cannula having at least one sharp point, said method including:
- disposing a first portion of a cannula within a storage means, said storage means having an axis of rotation, said cannula being fixedly disposed relative to said axis, said storage means being disposed within housing, a second portion of said cannula extending from said storage means exteriorly of said housing and being slidably disposed within an aperture in said housing;
- rotating said storage means about said axis and engaging a part of said first portion of said cannula with said storage means and wrapping said cannula around said storage means and simultaneously commencing drawing said second portion of said cannula into said housing at right angles to said axis;
- continuing said engagement until said point is fully withdrawn into said housing whereby said storage means destroys and stores said cannula within said housing.
