An apparatus for evaluating the tongue strength and coordination of a subject includes an intermediate device such as a lever which is pivotably attached to a coupling device and extends into a cavity of a nipple element. The lever is detached from the nipple and pivotable in response to deformation of the nipple element by a tongue force exerted on the nipple element by a subject during a suck-swallow-breathe sequence. The coupling device includes a sensing device to wirelessly transmit sensor outputs to a mobile device paired to the sensing device. The sensing device includes at least one sealed chamber defined by a membrane and a sensor. In one example, a first membrane and sensor senses pressure change in a fluid in the apparatus, and a second membrane and sensor is actuated by the intermediate device to sense deformation of the nipple element. A method using the apparatus is provided.

An intraoral device includes a mouthpiece for receiving a dentition of a user. The intraoral appliance further includes an oxygen sensor and an infrared radiation emitter. The oxygen sensor may include a photoplethysmography sensor. The intraoral device may further include a thermoelectric power source to supply power to the infrared radiation emitter and the photoplethysmography sensor.

A circuit housing (100) for a wearable intraoral application, including an inner layer (105-1) of a first material (101-1) for waterproof enclosure of an electronic circuit (103); and an outer layer (105-2) of a second material (101-2) for spatially fitting the circuit housing to a set of teeth (111), at least partially covering the first material (101-1).

A system and a method of using a vibrating gastrointestinal capsule in coordination with an ingestible medicament. The vibrating gastrointestinal capsule may include a housing; a vibrating agitation mechanism causing said housing to exert vibrations on an environment surrounding the vibrating gastrointestinal capsule; a power supply for powering said vibrating agitation mechanism; and a control mechanism for activating said vibrating agitation mechanism to operate in said vibration mode of operation, such that the vibration mode of operation at least partially transpires or completely transpires within an actual or estimated absorption time period of the ingestible medicament within the gastrointestinal tract of the subject.

The number n of times of chewing is counted by chewing number of times calculation means (13b.sub.2) based on a change in the distance l from a photorefiector (50), which is received together with time t by measurement value receiving means (13b.sub.1). To vary hardness h of a bag (30) to a stage that can be sensed, according to the number n of times of chewing, a required air pressure is set according to the current number n of times, based on a hardness/air pressure correspondence recording unit (13g) in which stages that have a significant difference therebetween and are stored in association with the number n of times of chewing are recorded. To realize the set air pressure inside the bag (30), the amount of sucking performed using a vacuum pump 20 is controlled by air pressure control means (13b.sub.4).

One aspect of the present disclosure include a method of utilizing an oro-motor device to activate an audio device, the method includes providing an oro-motor device having a sensor and a nipple; producing a signal when the nipple portion present in an infants mouth when the nipple portion yields a first measured pressure over an age appropriate predetermined threshold applied to the nipple portion by the infant; responsive to the signal, playing an age appropriate audio recording for a predetermined duration on an audio device; and raising the age appropriate predetermined threshold to a raised threshold proportionally to a difference between the first measured pressure application to the nipple portion and the age appropriate predetermined threshold.

A method includes obtaining a first physiological parameter indicative of a non-invasively measured airway pressure of a subject, obtaining a second physiological parameter indicative of a non-invasively measured air flow into the lungs of the subject, and estimating a third physiological parameter indicative of an intra-pleural pressure of the subject based on the first and second physiological parameters and generating a signal indicative thereof. An other method includes obtaining a first physiological parameter indicative of a non-invasively estimated intra-pleural pressure of a subject, determining a second physiological parameter indicative of a lung volume of the subject that is based on a third physiological parameter indicative of a non-invasively measured air flow into the lungs of the subject, and determining a work of breathing based on the first and second physiological parameters and generating a signal indicative thereof.

A system and method for prompting a patient experiencing ventilatory depression to breathe includes at least one sensor for detecting ventilatory depression by detecting inadequate breathing or lack of breathing in the patient. The system also includes one or more sensors for determining the type of breathing problem experienced by the patient. A sensor for detecting motion of the patient is used to determine whether the patient is moving. If inadequate or a lack of breathing is detected and the patient is not moving, the system provides verbal prompts or tactile stimuli to prompt the patient to breathe to improve patient ventilation.

The invention provides a sensor assembly embeddable within an oral appliance comprising a sensing means; and a data processing means coupled to the sensing means for processing data obtained by the sensing means; wherein the sensing means and the data processing means are sealed within a deformable layer.

A therapeutic device for intraoral use for treatment of tooth grinding and/or tongue pressing and/or snoring, having: at least two fastening devices for fastening the therapeutic device to at least one respective tooth of a user's upper jaw and/or lower jaw at least one sensor device equipped to detect pressure load events and/or sound events and/or vibration events in the user's oral cavity; at least one stimulation device for stimulating the user; a control and/or regulating unit for controlled and/or regulated operation of the stimulation device as a function of a pressure load event and/or sound event and/or vibration event that occurs; and a power supply
wherein the fastening devices are connected to each other with at least one flexible connecting piece, which is equipped to rest against outsides of the teeth and/or insides of the teeth leaving uncovered the free tooth ends of the teeth.
