  • Patent number: 11654227
    Abstract: A suction device that incorporates liquid to form a wet seal with a foreign body and/or debris, enabling an effective contact for extraction from canals, passages, and other bodily areas of a patient. A liquid chamber is formed between a distal nozzle and a distal end of a main body. The liquid chamber acts as a reservoir to facilitate a wet seal at the distal end of the embodiment. A vacuum provides suction through the embodiment, and a pressure release outlet is incorporated into the main body to allow for variation of suction force, affecting the moisture coverage presented to the area of extraction. Nozzle tip attachments may be affixed to the distal nozzle to further facilitate foreign body extraction. Other embodiments are described and shown.
