Date Dec. 12, 1991.The invention relates to disposable devices for introducing substances into body cavities of a patient. The device comprises a container for holding a substance which is connected to a tube ending in an opening which is inserted into a body cavity. The opening is sealed by a frangible seal located inside the opening. An actuating rod ruptures and removes the seal upon actuation. The actuating rod is provided with supporting rods extending to the container which are connected to the container by frangible connections. The supporting rod serves as a safe-guard against accidental rupture of the seal and as a guide for a controlled movement of said the actuating rod. The supporting rod also defines and protects an area to be kept sterile. The invention also relates to a moulding apparatus and to a method for making said device.
