Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an upper respiratory tract auxiliary breathing device and a control method thereof. Background Art

[0002] As we all know, snoring is a common symptom. Figure 1 As shown in the figure, snoring is mainly caused by the relaxation of cheek muscles during sleep, which causes the lower jaw to droop naturally and the mouth to open, which in turn causes the soft palate to relax, the tongue root to fall back, and the airway to narrow. Under the impact of air, the muscles vibrate and start snoring. Not only does it make you rest poorly, it also affects the normal sleep of others. In addition, the oral and pharyngeal mucosa are directly stimulated by dry cold air, which reduces people's resistance. In addition to making the body feel dry mouth and tongue, it often leads to upper respiratory tract infection and even suffocation.

[0003] Especially after the operation, when the patient enters the recovery room to recover from anesthesia, he will fall asleep due to anesthesia, which can easily lead to upper airway obstruction due to tongue drooping. The upper airway becomes narrow and prone to snoring and even suffocation. Snoring and tongue drooping leading to airway obstruction are very common, and most people have them (especially obese and middle-aged and elderly people), which can lead to hypertension, heart disease, premature aging, and even diabetes. For minimally invasive surgery with surgical robots, this situation in patients during the perioperative period is also a very important reason for slow recovery.

[0004] There are four main solutions to the above-mentioned upper airway obstruction problem: (1) surgical methods, such as otolaryngology surgery and oral and maxillofacial surgery, to correct the anatomical narrowing of the nose and pharynx, expand the area of ​​the oropharyngeal cavity, relieve upper airway obstruction or reduce airway resistance; (2) positive pressure ventilation, continuous positive airway pressure ventilation through the nose to assist breathing; (3) oral negative pressure, by wearing a device to maintain oral negative pressure suction, so that the upper airway is open and the upper airway obstruction problem is improved; (4) braces components, through the components to support the drooping upper palate, against the tongue, to prevent the root of the tongue from falling and causing upper airway obstruction; these four invasive assisted breathing methods are prone to damage to patients, and patients are also prone to feel uncomfortable.

[0005] There are also some non-insertion snoring devices in the prior art. One is the mandibular snoring device, which is attached to the user's mandibular position and widens the upper airway by pushing the mandibular position, thereby achieving the effect of stopping snoring; the other is the tongue snoring device, which is used to fix the user's tongue and can effectively prevent the tongue from falling back to keep the airway unobstructed, thereby achieving the effect of stopping snoring. Since the patient sleeps for a long time after anesthesia, these two snoring devices are prone to produce discomfort at the site of action of the patient after long-term use, which will also affect the effect of stopping snoring.

Detailed implementation manners

[0029] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and effects of the upper respiratory tract assisted breathing device and its control method proposed according to the present invention as follows: [Embodiment 1] Figure 2This is one of the structural schematic diagrams of the upper airway auxiliary breathing device in Example 1 of the present invention. Figure 3 This is the second structural schematic diagram of the upper airway auxiliary breathing device in the first embodiment of the present invention. Figure 4 This is the third structural diagram of the upper respiratory tract auxiliary breathing device in the first embodiment of the present invention. Figures 2 to 4 As shown, an upper airway auxiliary breathing device provided in the first embodiment of the present invention includes a tongue fixer 10, a lower jaw fixer 20 and a linkage device 30. The tongue fixer 10 is used to fix the tongue and move it synchronously, the lower jaw fixer 20 is used to fix the lower jaw and move it synchronously, and the linkage device 30 is connected to the tongue fixer 10 and the lower jaw fixer 20 respectively and is used to make the tongue fixer 10 and the lower jaw fixer 20 mutually linked, that is, the tongue fixer 10 and the lower jaw fixer 20 are mutually linked through the linkage device 30. When the tongue fixer 10 moves the tongue, the lower jaw fixer 20 will also move the lower jaw synchronously.

[0030] When the tongue fixer 10 moves the tongue from the first tongue position to any second tongue position, the linkage device 30 drives the mandibular fixer 20 to move the mandible from the first mandibular position to the corresponding second mandibular position; or, when the mandibular fixer 20 moves the mandible from the first mandibular position to any second mandibular position, the linkage device 30 drives the tongue fixer 10 to move the tongue from the first tongue position to the corresponding second tongue position. As an example, at the first tongue position, the tongue fixer 10 pulls out a portion of the tongue (2 cm); at the second tongue position, the tongue fixer 10 pulls out a portion of the tongue (3 cm). At the first mandibular position, the mandibular fixer 20 adjusts the mandibular position (e.g., 1.5 cm) so that the tongue moves forward as a whole and does not sag, causing respiratory obstruction; at the second mandibular position, the mandibular fixer 20 adjusts the mandibular position (e.g., 0.5 cm).

[0031] Optionally, the unobstructed effect of the airway when the tongue is in the first tongue position is greater than that when it is in the second tongue position, and the unobstructed effect of the airway when the mandible is in the first mandibular position is less than that when it is in the second mandibular position. Alternatively, the unobstructed effect of the airway when the tongue is in the first tongue position is less than that when it is in the second tongue position, and the unobstructed effect of the airway when the mandible is in the first mandibular position is greater than that when it is in the second mandibular position. This ensures that the upper airway auxiliary breathing device can make the airway unobstructed through the tongue fixer 10 and / or the mandibular fixer 20 to prevent snoring and suffocation, while reducing the numbness caused by long-term use.

[0032] In this embodiment, the upper respiratory tract assisted breathing device includes a driver (not shown in the figure). The driver is connected to the linkage device 30 and is used to drive the tongue holder 10 and the mandible holder 20 to move through the linkage device 30, that is, to drive the tongue holder 10 and the mandible holder 20 to move through the driver, so as to adjust the positions of the tongue and the mandible. Of course, in other embodiments, the positions of the tongue and the mandible can also be adjusted manually. For example, the tongue holder 10 and / or the mandible holder 20 can be pulled by hand to adjust the positions of the tongue and the mandible.

[0033] Furthermore, the upper respiratory tract assisted breathing device includes a controller (not shown in the figure). The controller is connected to the driver and is used to control the working state of the driver. Specifically, the controller controls the linkage device 30 to alternately change between a first working state and a second working state through the driver. When the linkage device 30 is in the first working state, the tongue holder 10 fixes the tongue at a first tongue position, and the mandible holder 20 fixes the mandible at a first mandible position; when the linkage device 30 is in the second working state, the tongue holder 10 fixes the tongue at a second tongue position, and the mandible holder 20 fixes the mandible at a second mandible position. The controller controls the driver to control the linkage device 30 to alternately change between the first working state and the second working state, so as to prevent the tongue holder 10 and the mandible holder 20 from fixing the tongue and the mandible at the same position for a long time, and prevent the user from having a tingling discomfort.

[0034] As Figure 2 shown, in one embodiment, the linkage device 30 includes a housing 31, a first guide wheel 321 and a connecting rope 33.

Wherein, the driver is used to drive the first guide wheel 321 to rotate, so as to control the movement of the connecting rope 33, so that both ends of the connecting rope 33 drive the tongue holder 10 and the mandible holder 20 to move.

[0035] As Figure 3As shown, in another embodiment, the linkage device 30 includes a housing 31, a first guide wheel 321, a second guide wheel 322, and a connecting rope 33.

The number of drivers can be one, and it drives the first guide wheel 321 or the second guide wheel 322 to rotate. Of course, the number of drivers can be two, and it drives the first guide wheel 321 and the second guide wheel 322 to rotate. By providing the first guide wheel 321 and the second guide wheel 322, it is convenient to control the connection direction of the connecting rope 33 with the tongue body fixator 10 and the mandibular fixator 20.

[0036] As Figure 4 shown, in another embodiment, the linkage device 30 includes a housing 31, a first guide wheel 321, a second guide wheel 322, a connecting rope 33, and a slider 34. The first guide wheel 321 and the second guide wheel 322 are both mounted on the housing 31 and can rotate on the housing 31. The first guide wheel 321 and the second guide wheel 322 are arranged side by side. The connecting rope 33 includes a first connecting rope 331 and a second connecting rope 332. The slider 34 is slidably mounted on the housing 31 and can slide between the first guide wheel 321 and the second guide wheel 322. One end of the first connecting rope 331 is connected to the slider 34, and the other end of the first connecting rope 331 passes through the first guide wheel 321 and is connected to the tongue body fixator 10; one end of the second connecting rope 332 is connected to the slider 34, and the other end of the second connecting rope 332 passes through the second guide wheel 322 and is connected to the mandibular fixator 20. By sliding 34, the movement of the first connecting rope 331 and the second connecting rope 332 is controlled, so that the first connecting rope 331 and the second connecting rope 332 respectively drive the tongue body fixator 10 and the mandibular fixator 20 to move. Among them, the driver is used to drive the slider 34 to slide between the first guide wheel 321 and the second guide wheel 322 to control the first connecting rope 331 and the second connecting rope 332 to drive the tongue body fixator 10 and the mandibular fixator 20 to move respectively, while the first guide wheel 321 and the second guide wheel 322 respectively play a guiding role for the first connecting rope 331 and the second connecting rope 332.

Among them, the first guide wheel 321 and the second guide wheel 322 can be interconnected through a gear structure. The driver is used to drive the first guide wheel 321 and / or the second guide wheel 322 to rotate. The number of drivers can be one and drive the first guide wheel 321 or the second guide wheel 322 to rotate; Of course, the number of drivers can be two and drive the first guide wheel 321 and the second guide wheel 322 to rotate. The first guide wheel 321 controls the movement of the tongue body fixator 10 through the first connecting rope 331, and the second guide wheel 322 controls the movement of the mandible fixator 20 through the second connecting rope 332.

It can be imagined that when in use, the tongue is extended into the tongue-shaped channel 17 until the tongue-shaped channel 17 is closed, and the diaphragm 19 forms two divided spaces between the first negative pressure chamber 15 and the tongue-shaped channel 17. The tongue body fixer 10 is made of a soft material. In the present embodiment, the tongue body fixer 10 is made of medical rubber and has elastic deformation properties. An avoidance notch can also be provided at one end of the tongue-shaped fixing portion 16 away from the tongue cover 14. The avoidance notch has a giving way effect, which prevents the tongue body fixer 10 from cutting the frenulum of the tongue and causing discomfort, and can make the tongue-shaped fixing portion 16 adapt to tongues of different sizes through deformation, and has stronger wrapping and versatility.

[0048] in, Figure 9 When the negative pressure tongue holder is applied to the upper airway auxiliary breathing device in Examples 1 to 3, the connecting rope 33 is directly fixed to the tongue cover 14 to move synchronously with the tongue; when in use, the external suction device sucks air into the first negative pressure chamber 15 through the air hole 141 and drives the diaphragm 19 to move, so that the tongue-shaped channel 17 can suck the tongue. Figure 9When the negative pressure tongue holder is applied to the upper airway auxiliary breathing device in the fourth embodiment, the first air guide tube 371 is directly connected to the air hole 141, and the first negative pressure chamber 15 is inhaled or inflated through the air hole 141, so as to control the tongue to move in the tongue-shaped channel 17. When applied to the fourth embodiment, the negative pressure tongue holder may also include an annular limiting portion 18 arranged on the circumferential outer side of one end of the tongue-shaped fixing portion 16 close to the tongue cover 14. In addition, when the annular limiting portion 18 is contained in the mouth, the annular limiting portion 18 is placed between the lips and the teeth and the outer wall of the side away from the tongue cover 14 abuts against the outer wall of the teeth, that is, the positioning of the tongue holder 10 in the mouth is achieved, and the tongue holder 10 is prevented from being separated from the tongue after the tongue shakes in the mouth, thereby enhancing the tongue fixing effect of the negative pressure tongue cover snoring device. A clearance gap may be provided on the annular limiting portion 18. The gap has a giving way effect, which prevents the tongue holder 10 from cutting the upper lip frenulum and causing discomfort, and makes the annular limiting part 18 fit the structure inside the mouth more closely, that is, the annular limiting part 18 can be deformed to be suitable for mouths of different sizes, which is ergonomic and has stronger wrapping and versatility. The external support structure of the annular limiting part 18 can effectively prevent the teeth from biting the tongue.

[0049] Figure 10 Schematic diagram of the cross-sectional structure of the mandibular fixator in the present invention. In the first to fourth embodiments of the present invention, Figure 10 As shown, the mandibular fixator 20 can be a negative pressure mandibular fixator, and the negative pressure mandibular fixator includes a main body 21, an adsorbent 22 and an air nozzle 23. The main body 21 includes a main body outer layer 211 and a main body inner layer 212, and a second negative pressure chamber 21a is provided between the main body outer layer 211 and the main body inner layer 212. The main body inner layer 212 is connected to the main body outer layer 211 through a second fold portion 213 and can move on the main body outer layer 211. The main body inner layer 212 includes a soft rubber support ring 212a. Each adsorbent 22 can be arranged on the outer side of the main body inner layer 212. The adsorbent 22 can be a component for adsorbing the user's skin. For example, the adsorbent 22 can be a suction cup. As an example, one end of the adsorbent 22 can be bonded to the outer side of the main body inner layer 212. The outer side of the main body inner layer 212 can be the side that contacts the user when in use. Each of the adsorbents can be provided with a through hole, and the provided through hole can be connected to the cavity.

[0050] in, Figure 10When the negative-pressure mandibular fixator in [the device] is applied to the upper respiratory tract assisted breathing device in Embodiments 1 to 3, the connecting rope 33 is directly fixed to the main body 21 to drive the mandible to move synchronously; during use, an external suction device sucks air through the air nozzle 23 into the second negative-pressure chamber 21a between the outer main body layer 211 and the inner main body layer 212, so that the suction attachment 22 fixes the skin of the mandible. Of course, when applied to Embodiments 1 to 3, the second pleat portion 213 may not be provided on the outer main body layer 211. Figure 10 When the negative-pressure tongue fixator in [the device] is applied to the upper respiratory tract assisted breathing device in Embodiment 4, the second air duct 372 is directly connected to the air nozzle 23, and through the air nozzle 23, air is sucked into or inflated into the second negative-pressure chamber 21a between the outer main body layer 211 and the inner main body layer 212, so that the suction attachment 22 fixes the skin of the mandible, and controls the inner main body layer 212 to move on the outer main body layer 211 through the second pleat portion 213 to drive the mandible to move.

[0051] The present invention also provides a control method for an upper respiratory tract assisted breathing device, which is used for the upper respiratory tract assisted breathing device as described above. The control method includes: At intervals of a preset time (for example, 30 minutes, and the specific time can be set by oneself), the controller controls the linkage device 30 to alternately change between the first working state and the second working state through the driver. When the linkage device 30 is in the first working state, the tongue fixator 10 fixes the tongue at the first tongue position, and the mandibular fixator 20 fixes the mandible at the first mandible position; when the linkage device 30 is in the second working state, the tongue fixator 10 fixes the tongue at the second tongue position, and the mandibular fixator 20 fixes the mandible at the second mandible position. By controlling the driver at intervals by the controller to control the linkage device 30 to alternately change between the first working state and the second working state, it is avoided that the tongue fixator 10 and the mandibular fixator 20 fix the tongue and the mandible at the same position for a long time, preventing the user from experiencing the uncomfortable feeling of soreness and numbness.
