The embodiment provides a high-volume evacuation tip perforated with round shape apertures covered by vent shells with upgraded capability of capturing escaping saliva and surgical debris during dental operation, as well as its total mass flow capability with soft silicone rubber nozzle. The high-volume suction tip for dental procedures has a cylinder or tubular-shaped, having two open ends. Forward-facing end has a soft silicone rubber nozzle is round in shape reducing patient pain and discomfort due to contact of hard plastic suction with soft tissue of patient with several vertical milling cutters to improve maximum effectiveness of fluid absorption, preventing clogging a surgical aspirator and prevent traumatic absorption of the patient tongue. Posterior end has vertical cutting shape. The suction tip has increase impact force compare to similar suction tips without the plurality of apertures or with few of them.

An effectively-support-type oxygen inhalation and sputum aspiration oropharyngeal airway device, comprising an inner airway body provided from a proximal end to a distal end, and a support plate parallel tongue surface and having -a-certain width; the support plate comprises a proximal end positioned on the front face of inner airway body and constituting the wall of duct, and a distal bending portion with bending angle of 0-180; the front face of distal bending portion is provided with at least two evenly distributed projections, recesses, or through holes; the surfaces of the projections facing to teeth are smooth and the surfaces of facing to pharynx have a height of 1-2 mm, or the recessing depth of recesses is 0.5-1 mm, or the diameter of through holes is 1-3 mm; the inner airway body provided from a proximal end to a distal end integrates a sputum aspiration duct and an oxygen inhalation duct.

An apparatus and method for use in treating tinnitus, employs a sound processing unit, a tactile unit, and an interface therebetween. The tactile unit comprises an array of stimulators each of which can be independently actuated to apply a tactile stimulus to a subject, and an input for receiving a plurality of actuation signals from the interface and directing individual actuation signals to individual stimulators. The sound processing unit receives an audio signal at an input, analyses the signal with a digital signal processor to generate the actuation signals which are representative of the audio signal, and provides the plurality of actuation signals to the interface. In a preferred embodiment the digital signal processor divides the audio signal into a series of frames in the time domain, performs a transform on each frame to generate a set of coefficients representing said frame, and maps the set of coefficients to a set of actuation signals to be applied to the array.

Systems and methods for improving airway patency are disclosed. An oral device is positioned in the oral cavity and applies a negative pressure to the oral cavity. The oral device has pressure delivery ports directed toward an anterior surface of the soft palate when positioned therein. The negative pressure generates an air flow out of the oral cavity. A pressure tube is coupled to the oral device to provide the applied negative pressure. A pressure source is coupled to the pressure tube to generate the applied negative pressure. A collector is coupled to the pressure tube and/or pressure source to collect liquid, typically saliva, from the air flow out of the oral cavity. The collector is disposed outside of the oral cavity and coupled to the oral device.

A standardized cartridge for dispensing accurate, measured doses of cannabis-based formulations that may be used interchangeably in a multiplicity of accessory devices for ingestion of the formulation in different modalities, and for which the formulation may be changed simply by swapping out the cartridge for one with a different formulation.

Example devices and methods of tongue stimulation for communication of information to a user are disclosed herein. In an example, a tongue stimulation device may include a body configured to be placed entirely within a mouth of the user and atop the tongue of the user. An array of electro-tactile elements may be distributed on the body, wherein each of the electro-tactile elements is configured to stimulate an area of the tongue adjacent the electro-tactile element. A wireless receiver coupled to the body may be configured to receive stimulation information wirelessly from outside the mouth of the user. At least one processing unit coupled to the body may be configured to transform the received stimulation information into a stimulation signal for each of the electro-tactile elements, and to provide the stimulation signals to the electro-tactile elements.
