1. Field of Invention
This invention pertains to a device for removing fluid accumulated in a person's ear canal. More particularly, this invention pertains to a device that is operated by a person, who provides suction power, to control the removal of fluid that has entered the ear canal, such as by swimming or bathing.
2. Description of the Related Art
The ear canal is prone to collection of water after swimming, diving, surfing, and the like. Accumulation of water within the ear and development of infections resulting from ear-water accumulation are common. Non-mechanical hand held curettes have been the traditional method of wax removal by physicians. Fluid removal is typically performed in a physician's office by using large electrical powered vacuum pumps connected to tubing and to narrow gauge tips under direct visual observation to evacuate fluid and debris. Cotton tipped swabs are often used inappropriately in the ear canal to remove wax and fluid, however, such use can cause trauma to the tissues of the ear as well as worsen the impaction of fluid and debris.
Numerous devices have been proposed and implemented for extracting fluids, particulates, and other matter from different orifices and tissues of human and animal bodies. Among them, U. S. Pat. No. 69,110, issued to Morris Mattson on Sep. 24, 1867, discloses a flexible tube interposed between an elastic bulb and a discharge pipe. The elastic bulb provides suction to the discharge pipe in order to take up and discharge fluids.
U. S. Pat. No. 4,334,538, issued to Steven K. Juhn on Jun. 15, 1982, discloses an aspirator for manually collecting liquid samples. The '538 device comprises a handle connected to a vacuum source. The handle has a sample collection vial fitting into a cavity in the handle with a finger control vent in the cavity. A tube leads into the sample collection vial and functions as the probe for the sample to be collected.
U. S. Pat. No. 5,062,835, issued to Carlos A. Maitz on Nov. 5, 1991, discloses an aspirator device for removing body fluids, comprising a fluid collector with an air-type chamber attached to a flexible tube to be inserted in a body cavity. The fluid collector is connected to a manually operable vacuum means or squeeze bulb. The manually operable vacuum means is operatively associated with first and second one-way valves establishing a vacuum for removing and depositing bodily fluids in the fluid collector.
U. S. Pat. No. 5,665,094, issued to Robert Arlin Goldenberg on Sep. 9, 1997, discloses an apparatus for collecting a middle ear fluid specimen through the ear drum of a patient. The '094 device utilizes a hollow needle mountable on a bulb. The bulb is operatively adapted to draw a specimen of middle ear fluid into the hollow needle when the needle is mounted on the bulb.
U. S. Pat. No. 6,059,803, issued to Daniel A. Spilman on May 9, 2000, discloses a portable hand held ear vacuum device for removing fluid and debris from an ear canal. The '803 device includes a handle with a motor linked to a fan and a control switch. A collection chamber for collecting fluid and other debris from an ear canal is secured to the handle. The collection chamber has a reservoir for collecting and storing accumulated fluid and debris from the ear canal. An ear insertion element is secured to the collection chamber. The ear insertion element has an aperture continuous with the reservoir in the collection chamber. The motor in the handle creates a vacuum within the collection chamber, enabling fluids and debris to be drawn from the ear canal into the reservoir by suction.
An ear fluid removal device for manually removing fluid and debris from the ear canal is disclosed. The ear fluid removal device provides a tool for removing fluid, particulates, or other debris from the ear canal while reducing the possibility of injury to the ear canal or surrounding tissues.
The ear fluid removal device includes an elongated flexible tube attached to an earpiece. The tube has a first end and a second end. The first end is adapted to be received by the mouth of a user. The second end is secured to the earpiece. The flexible tube is of sufficient length to span the distance between the mouth of the user and the user's ear. In one embodiment, the flexible tube is at least translucent and is of sufficient length as to allow the user to visually observe and monitor the aspiration and extraction of fluid and debris from the ear canal of the user.
In one embodiment, the earpiece is a piece of resiliently deformable material adaptable to be received by the ear of a user. The deformability of the earpiece allows the earpiece to compress for insertion and expand to substantially fill and conform to the contour of the user's ear canal. In one embodiment, the earpiece is a single piece of fluid-permeable material, such as open-cell foam. The earpiece connects to the tube second end such that the earpiece substantially surrounds and encloses the tube second end.
Another embodiment provides an earpiece having a through-opening, the through-opening receiving the flexible tube second end. In this embodiment, the earpiece is a piece of substantially fluid-impermeable material, such as closed-cell foam. In still another embodiment, the earpiece includes a piece of resiliently deformable material, such as open or closed-cell foam, substantially covered by a fluid-impermeable membrane.
The above-mentioned features of the invention will become more clearly understood from the following detailed description of the invention read together with the drawings in which:
An ear fluid removal device for manually removing fluid and debris from the ear canal is disclosed. The ear fluid removal device provides a tool for removing fluid, particulates or other debris from the ear canal while reducing the possibility of injury to the ear canal or surrounding tissues. The ear fluid removal device allows the user to control the specific level of suction applied to the ear canal, and the device is usable by most individuals without specific medical training.
The flexible tube 102 is of sufficient length to span the distance between the mouth 114 of the user 112 and the user's ear 116. In one embodiment, the flexible tube 102 is of sufficient length as to allow the user 112 to visually observe the flexible tube 102 while the earpiece 104 is inserted into the user's ear 116 and the tube first end 106 is inserted into the user's mouth 114. Additionally, at least a portion of the flexible tube 102 is translucent, such that the user 112 is able to determine the presence of fluid and debris inside the tube 102. The translucent tube 102 allows the user 112 to visually monitor the aspiration and extraction of fluid and debris from the ear 116. This feature allows the user to monitor collection of fluid and debris within the flexible tube 102, so as to avoid inhalation of fluid and debris removed from the ear 116. In another embodiment, the tube 102 is of such a length that a portion of the tube 102 serves as a reservoir for the collection of any fluid and/or debris collected from the ear 116, thereby preventing the inhalation of any fluid or debris by the user 116. Such a length would be sufficient if the tube 102 forms at least one loop between the two ends 106, 108 when the device 100 is in use.
In use, the earpiece 104 is inserted into the ear 116 of the user 112, and the tube first end 106 is inserted into the user's mouth 114. The earpiece 104 absorbs fluid and particulates within the ear canal. The flexible tube 102 serves as a storage reservoir for the removed fluid and debris. The user 112 applies suction to the tube 102 by sucking on the tube first end 106 with the user's mouth 114. The suction provided by the user 112 creates negative pressure within the flexible tube 102, which in turn creates negative pressure within the pores of the earpiece 104. This vacuum within the earpiece 104 helps to increase the absorption of fluid by the earpiece 104 within the ear canal. The user 112 views the flexible tube 102 to monitor the aspiration and collection of fluid and debris from the ear 116. In another embodiment, the tube 102 is of sufficient length that it serves as a reservoir for the collection of any fluid and/or debris collected from the ear 116. After fluid and debris is absorbed by the earpiece 104, the user 112 removes the earpiece 104 from the ear 116. The earpiece 104 and the flexible tube 102 are then cleaned, and the fluid and debris is discarded. Alternatively, after removal from the ear 116, the earpiece 104 itself is discarded and replaced.
In the illustrated embodiment, the earpiece 104′ includes a piece of substantially fluid-impermeable material. In one embodiment, the earpiece 104′is made of an closed-cell foam. In another embodiment, the earpiece 104′includes a piece of resiliently deformable material with the cylindrical outer portion substantially covered by a fluid-impermeable membrane and the flat end inserted into the ear 116 adapted to absorb and pass fluids. That is, the cylindrical face of the earpiece 104 has a fluid-impermeable surface.
