Description

Device for improving sleep respiratory obstruction

[ technical field ] A method for producing a semiconductor device

The present invention relates to a device for improving sleep breathing obstruction, and more particularly, to a device for pulling the tongue of a user outward.

[ background of the invention ]

Sleep apnea (Obstructive sleep apnea) is a symptom that when a patient sleeps, especially lies down, his respiratory tract is blocked by his own tongue and soft jaw, and thus the patient cannot breathe smoothly. The immediate cause of this condition is that when the patient sleeps, the tongue collapses rearward of the body due to gravity and relaxation of the body tissue, blocking the passage of the mouth and trachea, and the collapsing tongue also presses the patient's soft jaw, causing it to block the passage of the nasal and trachea. Obviously, the patient is difficult to breathe due to the obstruction of sleeping breathing, snoring easily occurs, and the life safety of the patient is even threatened.

Obviously, sleep breathing obstruction can be addressed by pulling the patient's tongue away from the collapsed position by an external force. One of the traction schemes is to fix the tongue of the patient by negative pressure adsorption and pull the tongue outwards. The problem with this type of solution is that the related fittings are mass produced, the stroke of the patient's tongue being pulled cannot be freely adjusted, while the physiology and severity of symptoms vary for each patient, and a single non-adjustable pull stroke is not necessarily suitable for all patients: the same pulling stroke, which may be too large for some patients, causes discomfort; and too small for some patients to completely dislodge the tongue from the collapsed position. Of course, customizing the fitting for each individual patient may solve the above problem, but the cost may significantly increase.

In addition, in the existing negative pressure traction scheme, the negative pressure source is placed at the bedside of the patient, a sufficiently long pipeline is required to be configured to connect the patient and the negative pressure source, and during the sleeping process of the patient, the long pipeline can be pressed, entangled or tightened due to the unconscious activity of the patient, so that the negative pressure is interrupted or leaked, and the use effect is influenced.

Therefore, there is a need for an improved device for improving sleep respiratory obstruction that overcomes the above problems.

Since the preset reverse sound wave signal occurs prior to the actual reverse sound wave signal, the preset reverse sound wave (i.e., the first noise reduction sound wave) also occurs prior to the actual reverse sound wave (i.e., the second noise reduction sound wave). And because the first noise reduction sound wave and the actual noise are not in strict phase opposition, the first noise reduction sound wave and the actual noise cannot be completely offset after being superposed, residual noise sound waves are left, the residual noise sound waves are also superposed with the actual noise sound waves and received by the microphone, the active noise reduction of the next round is carried out, and second noise reduction sound waves are generated.
