Abstract
A single-use suppository insertion device includes a barrel, a plunger configured to be movably coupled to the barrel, and a disabling feature of the barrel or the plunger. The disabling feature may be configured to be activated during operational motion of the plunger relative to the barrel, such as during insertion of or withdrawal away from a suppository. The device can include a structural element of the barrel or the plunger configured to engage with the disabling feature of the barrel or the plunger during insertion of or withdrawal away from the suppository to activate the disabling feature. The disabling feature may be implemented in a number of ways to ensure single-use operation of the single-use suppository insertion device.
Claims20
A single-use suppository insertion device comprising:
- a plunger;
- a barrel receiving the plunger;
- and
- an insert between the plunger and the barrel and configured such that a movement of the plunger in the barrel causes engagement between the insert and the barrel or the plunger that prevents a reversal of the movement of the plunger in the barrel.
A method of inserting a suppository, comprising:
- forcing, via movement of a plunger along a barrel, release of the suppository from the barrel;
- and
- preventing reversal of the movement of the plunger along the barrel by engaging, by a insert positioned between the plunger and the barrel, the plunger or the barrel.
A method of preventing re-use of a suppository insertion device, comprising:
- pushing a suppository off of the suppository insertion device by causing a movement of a plunger of the suppository insertion device relative to a barrel of the suppository insertion device;
- and
- physically disabling, in a manner mechanically caused by the movement of the plunger relative to the plunger, the plunger from repeating the movement relative to the barrel.
