Methods and devices are provided that are effective to remove an obstruction in a human airway and/or maintain an open airway. The methods and devices are particularly useful for patients suffering from snoring and/or OSA, and/or preventing upper airway obstructions in patients undergoing anesthesia. In one embodiment, the device includes a mouthpiece that is adapted to form a substantially sealed cavity within a human mouth, and a hollow elongate member having a first end that is coupled to the mouthpiece and that is in communication with the substantially sealed cavity, and a second end that is adapted to be coupled to a negative pressure generator. In use, a negative pressure generator can be attached to the hollow elongate member to create a negative pressure in a human mouth in response to an obstructed airway, thereby removing the obstruction. In particular, this device is effective to counteract the collapse of a patient's soft tissues of the upper airway to reopen the airway. The mouthpiece can also be used in combination with a nasal mask. In another embodiment, the oral appliance above also comprises a nasal mask, wherein the nasal mask provides a means of ventilation support, including but not limited to total mechanical ventilation, positive-end expiratory pressure, or continuous positive airway pressure. In use, such a device can provide complete patient ventilation and maintain an open upper airway.

Methods and devices are provided that are effective to remove an obstruction in a human airway related to snoring and/or OSA. In one embodiment, the device includes a mouthpiece that is adapted to form a sealed cavity within a human mouth, and a hollow elongate member having a first end that is coupled to the mouthpiece and that is in communication with the sealed cavity, and a second end that is adapted to be coupled to a negative pressure generator. In use, a negative pressure generator can be attached to the hollow elongate member to create a negative pressure in a human mouth in response to an obstructed airway, thereby removing the obstruction. In particular, this device is effective to pull a patient's tongue and/or soft tissues of the upper airway up and away from the posterior pharyngeal wall to reopen the airway.

The invention relates to a method for quickly detecting the intensity of four basic tastes (sour, sweet, bitter, and salty) in a liquid food by using an electronic tongue. The method comprises the following steps: preparing an HCl solution with a concentration of 0.01mol/L from distilled water as the activating solution of the electronic tongue (five tastes) sensor; using distilled water of the cleaning solution (pay attention to replacing new distilled water); adding the HCl solution with a concentration of 0.01mol/L as the calibration solution, so that the electronic tongue sensor can be used for analyzing samples after calibration; selecting four kinds of substances with four basic tastes with a concentration suitable for the normal concentration level in the human mouth as the basic samples; determining the number of cleaning beakers according to the number of the samples, wherein each sample is cleaned in the specific cleaning beaker, and the samples are cleaned according to the natural sequence; placing the electronic tongue sensor in each beaker for 120 seconds to detect the taste of the sample, and detecting for six times for each sample to obtain that the taste of the sample has a semi-logarithmic relationship with the response strength on the electronic tongue sensor; and carrying out macro operation by electronic tongue software on the results to obtain the relative intensity relationship between different concentrations of the basic taste substances on the electronic tongue.

A hydrogel for use in oral care. The hydrogel is ion beam cross-linked, the hydrogel is adapted to be disposed in the oral cavity and may be adapted to provide a denture fixative or may be loaded with a whitening agent for use in whitening one or more teeth and disposed on or adjacent one or more teeth and the whitening agent is slow-released to whiten the one or more teeth. Other loading materials may include materials for treatment of alveolitis or malodor, inter alia. The present invention is a new hydrophilic oral and dental cohesive hydrogel sheet designed to securely grip and cushion prosthetic devices in the human mouth with the further ability to slow release antimicrobial or other orally desirable agents. Additionally, the invention also provides a method of making an orally cohesive device that: 1) is easily adapted and applied to a removable dental prosthesis; 2) bonds well to alveolar ridge/palatal mucosa and denture acrylic materials; and 3) releases cleanly, with no tacky or thixotropic residue when the prosthesis is removed. The cohesive hydrogel gel device is a hydrogel-forming polymer mixed with water, optionally surrounding an internal scrim, and uses an electron-beam energy source to cause cross-linking. The method does not need any chemical additive to affect the cross-linking. Furthermore the beam energy can be adjusted to optimize the cohesive properties of either side of the device, as well as to compensate for addition of orally active agents, if any are chosen. The hydrogel sheets are pre-cut to fit most sizes of maxillary and mandibular full denture prostheses, but can be easily trimmed with a scissors by the end user for the ideal custom fit of any full or partial denture, in either arch.
