Abstract
Abstract A swimming apparatus that permits an individual with a laryngectomy to be able to swim. The apparatus comprises a mouthpiece, a throat sealing member and an air tube intercoupling the mouthpiece and sealing member. The sealing member is securely disposed to cover and seal about the throat stoma while having an opening to permit air passage to the throat. The mouthpiece is controlled by the swimmer as a valve to control airflow through the unobstructed air tube. Also included are first and second valves associated with the air tubes, a first valve being positioned at the mouthpiece and the second valve being disposed intermediate the ends of the air tube. The first valve is a one way valve permitting air flow through the air tube on an inhalation. The second valve is also a one way valve permitting air exhaust from the air tube during exhalation. Also, in accordance with the invention there is provided about the sealing member, an inflatable air chamber adapted to provide controllable sealing of the sealing member about the throat stoma.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
207 words
A swimming apparatus used to enable a person having a laryngectomy or the like to safely swim, said apparatus comprising; an elongated unobstructed air tube, a mouthpiece means at one end of the air tube tube having an air passage communicating with the air tube to enable air passage between the air tube and a person's mouth, a relatively flat sealing member having means forming a water tight seal about the throat stoma, said sealing member also having an air passage, means securing the other end of the air tube to the sealing member enabling air passage between the air tube and person's throat, and means holding the sealing member in water tight sealing relationship to the throat about the throat stoma, said means holding the sealing member comprising both a fastening means coupled to the sealing member for securing the sealing member to the person and a means defining a controllable inflatable air chamber attached to the apparatus in front of and adjacent to the sealing member for maintaining the sealing member in a water tight position about the throat stoma, whereby the person controls air flow in alternate directions corresponding to inhalation and exhalation through the air tube by interaction of the mouth and mouthpiece.
Claim 2
Dependent Claim
207 words
A swimming apparatus used to enable a person having a laryngectomy or the like to safely swim, said apparatus comprising; an elongated unobstructed air tube, a mouthpiece means at one end of the air tube tube having an air passage communicating with the air tube to enable air passage between the air tube and a person's mouth, a relatively flat sealing member having means forming a water tight seal about the throat stoma, said sealing member also having an air passage, means securing the other end of the air tube to the sealing member enabling air passage between the air tube and person's throat, and means holding the sealing member in water tight sealing relationship to the throat about the throat stoma, said means holding the sealing member comprising both a fastening means coupled to the sealing member for securing the sealing member to the person and a means defining a controllable inflatable air chamber attached to the apparatus in front of and adjacent to the sealing member for maintaining the sealing member in a water tight position about the throat stoma, whereby the person controls air flow in alternate directions corresponding to inhalation and exhalation through the air tube by interaction of the mouth and mouthpiece.
Claim 3
Dependent Claim
50 words
