Abstract: A sound muffling chamber covers a nose and mouth in an airtight manner. The sound muffling chamber includes a microphone that detects vocal sound waves in the sound muffling chamber and generates a voice signal. A digital signal processing system analyzes the voice signal and generates a voice cancellation signal. A sound silencing chamber includes a speaker that generates out of phase sound waves in response to the voice cancellation signal that superimposes on and cancels the vocal sound waves. A sound decelerator is positioned between the sound muffling chamber and the sound silencing chamber and configured to increase a traveling time of the vocal sound waves such that the vocal sound waves' arrival at the sound silencing chamber may be synchronized with the arrival of a voice cancellation signal. The sound muffling chamber may include inflatable cells separated by slats such that the sound muffling chamber is foldable.

Abstract: An endotracheal or tracheostomy tube with a cuff assembly includes a cuff pressure regulator and a leak detection system. Pressure sensors monitor and measure a tracheal wall pressure and pressures in the cuff assembly. An abnormal reading from the pressure sensors may initiate a cuff-pressure adjusting process. The leak detection system detects an air leak in the seal between the cuff assembly and the tracheal wall. A scented film with a predetermined scent is positioned on an inferior portion of the cuff assembly, distally from the seal with the tracheal wall. An air leak is indicated when the predetermined scent is detected in air in the trachea proximal to the cuff assembly. An air-circulation device generates air flow into the trachea such that a new batch of air may be sampled and tested. The detection of an air leak may initiate a cuff-pressure adjusting process.

Abstract: A cuff assembly for a tracheostomy tube includes an outer bladder and an inner cuff. The inner cuff is positioned adjacent to the tracheostomy tube, and the outer bladder is positioned adjacent to the inner cuff. The outer bladder is made with a less elastic material and operates at a higher relative pressure.

Abstract: An airway device includes an outertube and a scope channel partially enclosed by the outertube. An intraluminal space in the outertube, not occupied by the scope channel, provides a passageway for air flow to the patient. An esophageal cuff is disposed distally on the scope channel. When inflated, the esophageal cuff secures the airway device in the proximal esophagus of the patient and helps to prevent gastric reflux by mechanically blocking gastric content from entering into the larynx. An inflatable bladder is attached at an anterior surface of the scope channel between the esophageal cuff and a distal opening of the outertube. When inflated, the bladder forms a tubular ring that pushes against the epiglottis and/or other soft tissue towards a wall of the hypopharynx to produce an unhindered air passage into the patient's trachea.

The outer bladder is made with a less elastic material and operates at a higher relative pressure. The inner cuff is made with a more elastic or hyper-elastic material and operates at a lower relative pressure. A pressure controller independently adjusts the pressure within the inner cuff and the outer bladder. A secretion collection receptacle is formed by the cuff assembly and is evacuated via a suction catheter or channel.

Abstract: A mount that reversibly couples with an eyeglass-frame temple to enable adjustment of the balance of eyeglasses is presented. The mount includes a rigid outer shell whose interior area is filled with a resilient material. The rigid shell provides strength, while the deformability of the resilient material enables the mount to securely conform to the shape of any of a wide range of temple designs virtually anywhere along its length. Additional counterweights and/or other accessories can be attached to the mount, as desired. The shell includes a clamp that comprises a u-shaped frame and a hasp that is joined with the frame at a rotary joint. The hasp is rotated about the rotary joint to enable its attachment to, and release from, the frame. The free end of the hasp connects with the frame via a clasp that is configured to mitigate the inadvertent decoupling of the hasp and frame.
