  • Publication number: 20030105450
    Abstract: A device for delivering a beneficial agent within a body cavity such as the ear canal. The device preferably includes a soft resilient casing that can be compressed to fit at least partially within the ear canal. Once inserted in the ear canal, the casing expands to form a seal between a boundary defining the ear canal and the device. The soft casing preferably encapsulates the beneficial agent within a reservoir formed inside the soft casing. As the device is squeezed, the beneficial agent is ejected through a release point. The device then maintains the beneficial agent within the ear canal until the beneficial agent has had time to take effect.

  • Patent number: 6315761
    Abstract: Devices for injection of medicines into a human body are designed for one-time use during inpatient or outpatient treatment. The reuse of an injection device having a bellows 3 as an injection container is prevented by providing a locking attachment which prevents backward motion of a bottom 4 of the bellows 3 and which is mounted on elements of the device brought together during the injection (the bottom 4 of the bellows 3 and the housing/needle holder 1). A locking attachment is made in a form of a pair of interacting elastically deformable hooks 6 with a beveled catch and a female part in the form of a hole 7 with a ledge 8. At the instant the injection is completed, the sharpened end 10 of the needle 2 punctures a partition 9 in the bottom 4 of the bellows 3, further preventing reuse.
