Abstract
Abstract An oral therapeutic apparatus and a method of using the oral device for treating a patient undergoing a chemotherapy treatment are disclosed wherein the oral device is formed to be insertable within the patient's mouth and receive a circulated cooling medium to continuously and uniformly cool the patient's oral tissues including the gums, cheeks, tongue, roof and base of the mouth, to prevent the oral tissues from absorbing the chemotherapy agent to thereby prevent inflammation and oral sores.

An apparatus for cooling a patient's oral tissues while undergoing medical or dental treatment, comprising an oral therapeutic device having a body having imperforate wall portions which define a plurality of chambers in which a cooling medium may be retained, said body being formed of a biocompatible material which is shaped to be insertable in, and conform to, the contour of a patient's mouth.
Claim 2
Independent Claim
64 words
An apparatus for cooling a patient's oral tissues while undergoing medical or dental treatment, comprising an oral therapeutic device having a body having imperforate wall portions which define a plurality of chambers in which a cooling medium may be retained, said body being formed of a biocompatible material which is shaped to be insertable in, and conform to, the contour of a patient's mouth.
Claim 3
Dependent Claim
65 words
That apparatus of claim 1, in which said body includes a pair of outer wall portions defining at least one outer chamber, an intermediate bite portion extending from said pair of outer wall portions, and a pair of inner wall portions defining at least one inner chamber connected to said bite portion whereby a cooling medium may be contained in said inner and outer chambers.
Claim 4
Dependent Claim
