Description

Device for improving sleep obstruction of breathing

Technical field

The present invention relates to a device for improving sleep obstruction of breathing, in particular to a device for pulling the user's tongue outward.

Background technique

Obstructive sleep apnea is a symptom in which patients cannot breathe smoothly because their airways are blocked by their own tongue and soft palate during sleep, especially when sleeping. The direct cause of this symptom is that when the patient sleeps, due to the effect of gravity and the relaxation of human tissues, the tongue collapses to the back of the human body and blocks the passage of the oral cavity and trachea. The collapsed tongue also compresses the soft palate of the patient. Blocked the passage of the nasal cavity and trachea. Obviously, sleep breathing obstruction can cause breathing difficulties, snoring easily, and even endanger the life of the patient.

Obviously, by pulling the patient's tongue out of the collapsed position by external force, the sleep breathing obstruction can be solved. One of the traction schemes is to fix the patient's tongue through negative pressure adsorption and then pull it outward. The current problem with this type of solution is that the related accessories are mass-produced, and the stroke of the patient's tongue cannot be adjusted freely, and the physiological structure and severity of symptoms of each patient are different, a single unadjustable pulling stroke Not necessarily suitable for all patients: the same pulling stroke may be too large for some patients and cause discomfort; for some patients, it is too small and does not completely remove the tongue from the collapsed position. Of course, customizing accessories for each individual patient can solve the above problems, but the cost will increase significantly.

In addition, in the existing negative pressure traction scheme, the negative pressure source is placed on the bedside of the patient, and a long enough pipeline must be configured to connect the patient to the negative pressure source.

In this embodiment, the actuating member 8 is an elastic rubber ring, which is arranged between the rear shell 61B and the mask portion 11. During the assembly process, the The negative pressure source 6 applies an external force that moves it toward the mask portion 11, so that the actuator 8 is pressed by the rear shell 61B and the mask portion 11. When the positioning protrusion 122 enters the After the fixing groove 6152, the external force applied to the negative pressure source 6 and the base 1 can be released, and the actuator 8 exerts an elastic force away from each other on the rear shell 61B and the mask portion 11 , The positioning protrusion 122 and the fixing groove 6152 are relatively displaced in the front-to-rear direction until the positioning protrusion 122 enters the fixing section 6152A, the guide rail 615 also includes a block 6153, the card The block 6153 is located between the fixed section 6152A and the guide groove 6151.

The tongue fixing portion 51 is used to monitor the negative pressure at the tongue fixing portion 51. The measurement value of the negative pressure sensor 64 is transmitted to the controller 68. If the measurement value is less than the preset value, the The controller 68 increases the operating power of the negative pressure pump 62, and vice versa, reduces the operating power of the negative pressure pump 62. After passing the negative pressure sensor 64, the extracted gas passes through the one-way valve 65. The one-way valve 65 can be an existing one-way ball valve suitable for medical purposes. The one-way valve 65 only allows The gas flows unidirectionally from the tongue fixing part 51 to the negative pressure pump 62. Finally, the negative pressure pump 62 discharges the extracted gas from the negative pressure source 6 through the outlet 613.

In an ideal state, even if the negative pressure pump 62 stops working, a closed space that maintains negative pressure can be formed between the user’s tongue T and the one-way valve 65. Therefore, when the negative pressure sensor 64 detects When the negative pressure between the user’s tongue T and the one-way valve 65 is sufficient to keep the user’s tongue T fixed to the tongue fixing portion 51, the controller 68 can control the negative pressure pump 62 stop working to reduce power consumption.

The arithmetic unit generates a corresponding actual inverted acoustic wave signal according to the received noise signal, and the negative pressure pump is prestored in the register. 62. Before the arithmetic unit receives the noise signal generated by the microphone, the register transmits the pre-stored noise signal model to the arithmetic unit, and the arithmetic unit is producing the actual inverted sound wave The signal can generate the preset inverted sound wave signal before. A plurality of the speakers may be arranged around the negative pressure pump 62 to emit inverted sound waves at different angles, and the speakers may generate inverted sound waves according to the received inverted sound wave signals, whether actual or preset. The phase sound wave cancels out the noise of the negative pressure source 6.

Since the preset inverted acoustic wave signal occurs before the actual inverted acoustic wave signal, the preset inverted acoustic wave (ie, the first noise-reducing wave) also occurs before the actual inverted acoustic wave (ie, the second noise-reducing wave). In addition, since the first noise reduction wave and the actual noise are not strictly in phase, they cannot be completely cancelled out after the two are superimposed, leaving a residual noise sound wave. The residual noise sound wave will also be superimposed with the actual noise sound wave and will be received by the microphone, Perform the next round of active noise reduction to generate a second noise reduction wave.

In this embodiment, the negative pressure pump 62 and the active noise reduction unit 66 are both powered by the power supply 67, and the power supply of both is controlled by the controller 68 at the same time, according to the control of the controller 68 Signal, the active noise reduction unit 66 and the negative pressure pump 62 start and close at the same time, so that the active noise reduction unit 66 is only energized when the negative pressure pump 62 is working, reducing the active noise reduction unit 66 The energy consumption of the noise unit 66 extends the use time of the power supply 67 after each charge.
