Abstract

A sharps bagging apparatus has an access member with one or more conforming openings which conform to the profile of a retracted medical device to allow bagging collected retracted medical devices with a satisfactory degree of assurance that all or virtually all the devices are in the safe retracted condition. The access member is used with a collapsible disposal bag which may removably fill a disposal container or in one embodiment be fixedly secured to the access member. The access member is adapted to fit plastic or wire containers removably or lockedly. Sloping sides in the access member create a centering well which tends to center a retracted device and may include a triggering wall which can activate the retraction mechanism of an unretracted device. When the access member is provided with an attached collapsible bag, they can be stacked for economical transport and storage.

Claims

the conforming opening further including a “

T”

-shaped slot for receiving a radially enlarged part of a medical device and the safety shield includes a corresponding opening spaced below said slot to facilitate rolling movement of a medical device which enters the safety shield.

12. An access member for a sharps disposal container for safe disposal of a medical device having a sharp needle or blade, wherein the profile of the medical device in its safe condition is different than the profile of the medical device in its unsafe condition, comprising;

an access member adapted for use with a disposal container for sharps;

the access member having a conforming opening therein conforming to the profile of the medical device in its safe condition;

wherein the access member has an upper surface and a lower surface separated by a thickness and includes a safety shield spaced under the conforming opening, depending from the access member;

wherein said safety shield comprises a shelf directly under the conforming opening and opposed barriers on opposite sides of the conforming opening; and

said safety shield preventing passage of a medical device with a conforming profile from passing through the conforming opening in any orientation, unless it is in its safe condition.

13. The access member of claim 12 wherein said shelf is tilted with respect to the lower surface of the access member thereby creating a discharge opening for medical devices passing through the conforming opening.

14. The access member of claim 13 wherein the conforming opening includes a “

T”

-shaped slot for receiving a radially enlarged part of a medical device and the safety shield includes a corresponding opening spaced below said slot at approximately the level of the shelf to facilitate rolling of a medical device on the shelf toward the discharge opening.

15. An access member for a sharps disposal container for safe disposal of a medical device having a sharp needle or blade, wherein the profile of the medical device in its safe condition is different than the profile of the medical device in its unsafe condition, comprising;

an access member adapted for use with a disposal container for sharps;

the access member having a conforming opening therein conforming to the profile of the medical device in its safe condition;

said access member having sloping surfaces leading to the conforming opening in said access member, wherein a centering well is created which tends to cause a medical device with the conforming profile to automatically center itself in relation to the conforming opening and

whereby the medical device will pass through the conforming opening in the access member only in the safe condition of the medical device.

16. The access member of claim 15 wherein the profile of said medical device comprises a back end portion having an activation structure for a retraction mechanism and a front end having the needle and wherein the conforming opening includes a back end portion which presses the activation structure of said medical device.

17. The access member of claim 16 wherein an upright sharply sloping surface is provided in the access member at the back end portion of the conforming opening, said sharply sloping surface tending to operate the activation structure when an unretracted medical device with the conforming profile is attempted to be pushed through the conforming opening thereby causing the medical device to retract.

18. An access member for a sharps disposal container for safe disposal of a medical device having a needle, wherein the profile of the medical device in its safe condition is different than the profile of the medical device in its unsafe condition, comprising:
