APPLICATOR FOR APPLICATION OF A FLUID SUBSTANCE WITHIN A BODY CAVITY AND METHOD OF USE THEREOF

摘要

An applicator device for applying a fluid substance within a body cavity includes an applicator body for insertion into the body cavity. A chamber within the applicator body holds the fluid substance. A plunger applies pressure to the fluid substance in the chamber when pushed into the chamber, and creates suction when withdrawn. Lateral openings are each provided with one-way valves that enable outflow of the fluid substance through the opening from the chamber to an outer surface of the applicator when the pressure is applied by the plunger, and inhibit inflow of a fluid through the opening from outside the applicator into the chamber when the suction is created by the plunger. A stopping structure inhibits pushing motion at a stop position, enables motion past the stop position when an additional pushing force is applied, and enables withdrawal through the stop position without interference.

主权项

1. An applicator device for applying a fluid substance within a body cavity, the device comprising:
an applicator body that is configured for insertion into the body cavity; at least one chamber within the applicator body for holding the fluid substance; a plunger that is configured to apply a pressure to the fluid substance in the chamber when pushed into the chamber with a pushing motion, and to create a suction within the chamber when withdrawn from the chamber with a withdrawal motion; a plurality of lateral openings, each opening provided with a one-way valve that is configured to enable outflow of the fluid substance through the opening from the chamber to an outer surface of the applicator body when the pressure is applied by the plunger, and to inhibit inflow of a fluid through the opening from outside the applicator into the chamber when the suction is created by the plunger; and a stopping structure that is configured to inhibit the pushing motion at a stop position, to enable the pushing motion past the stop position when an additional pushing force is applied, and to enable the withdrawal motion through the stop position without interference.
