[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1-Figure 6 As shown, the present embodiment provides a non-invasive ventilator mask auxiliary fixing device, including a positioning frame 1, a positioning suction cup mechanism, a tightening mechanism, a lower strap 2, an adjustment connection mechanism, a connecting sleeve 3 and an upper strap 4, the positioning suction cup mechanism includes an embedded groove 5, a first pressure sensor 6, a suction cup seat 7 and a fixed suction cup 8, the lower side of the positioning frame 1 is symmetrically provided with an embedded groove 5, a suction cup seat 7 is provided in the embedded groove 5 through the first pressure sensor 6, the first pressure sensor is fixed to the bottom surface of the embedded groove, the suction cup seat is fixed on the first pressure sensor, and the outer side of the suction cup seat 7 is symmetrically provided with a fixed suction cup The disk 8 can be adsorbed onto the upper side of the ventilator mask and is used to position and install the mask, while facilitating the rapid replacement of the mask. Tightening mechanisms are symmetrically arranged on both sides of the positioning frame 1, and a lower strap 2 is arranged between the tightening mechanisms. A connecting sleeve 3 is arranged on the upper side of the positioning frame 1 through an adjustable connecting mechanism. The connecting sleeve is used to fit with the patient's forehead. The position of the connecting sleeve can be adjusted according to different patients by adjusting the connecting mechanism to make it more comfortable to wear. An upper strap 4 is arranged on the front side of the connecting sleeve 3 through a tightening mechanism, which is connected to the upper side of the positioning frame and is used for auxiliary fixation of the mask.

[0022] A second pressure sensor 9 is embedded on the inner side of the connecting sleeve 3, and a soft rubber layer 10 is attached to the connecting sleeve 3 outside the second pressure sensor 9, which can monitor the binding compression force of the upper strap in real time, and the wearing of the auxiliary mask makes the patient more comfortable to wear. The inner side of the positioning frame 1 is a hollow structure and is provided with a main control circuit board 11. The main control circuit board 11 has a built-in control system for the control and operation of the entire device. A connecting belt 12 is provided between the rear side of the upper strap 4 and the rear side of the lower strap 2, which can prevent the upper strap and the lower strap from falling off due to excessive spacing.

[0023] The first pressure sensor, the second pressure sensor and the winding motor in the tightening mechanism are all electrically connected to the main control circuit board. The main control circuit board collects the data from the pressure sensors and compares them with the preset pressure data to generate a control signal for the tightening mechanism to control the tightness of the lower strap and the upper strap.

[0024] The tightening mechanism includes a winding box 13, a winding bin 14, a winding motor 15, a winding shaft 16 and a plug-in battery 17. The winding box 13 is arranged on both sides of the positioning frame 1 and the front side of the connecting sleeve 3. The winding bin 14 is arranged in the winding box 13. The winding motor 15 is arranged on the lower side of the winding bin 14. The output end of the winding motor 15 extends into the winding bin 14 and is rotatably provided with a winding shaft 16. A plug-in battery 17 is arranged on the upper side of the winding box 13. Multiple groups of plug-in batteries are used to power the entire device.

[0025] The winding box 13 on the positioning frame 1 is provided with a strap groove 18 on the outer side surface away from the positioning frame 1, and the two ends of the lower strap 2 extend into the strap groove 18 and are respectively fixedly connected to the winding shaft 16 in the winding boxes 13 on both sides. When the lower strap is adjusted, the winding motors inside the winding boxes on both sides rotate synchronously to reel in or loosen the lower strap, and the winding box 13 on the connecting sleeve 3 is symmetrically provided with strap grooves 18 on both sides, and the two ends of the upper strap 4 extend into the strap grooves 18 and are fixedly connected to the winding shaft 16. Since the two ends of the upper strap are fixed to a group of winding shafts, when the winding motor drives the winding shaft to rotate, the upper straps on both sides are synchronously reeled or loosened, thereby realizing the tightness control of the upper strap.

[0026] The adjustment connection mechanism includes a connecting seat 19, a movable sleeve seat 20, an adjustment strip 21, a ratchet groove 22 and an elastic tooth 23. The movable sleeve seat 20 is arranged on the upper side of the positioning frame 1 through the connecting seat 19. The connecting seat is frame-shaped and fixed on the upper side of the fixed frame. The movable sleeve seat is a sleeve structure and is movably sleeved on the connecting seat. The movable sleeve seat 20 is fixedly provided with an adjustment strip 21. The front side of the adjustment strip 21 is provided with a ratchet groove 22. The elastic tooth 23 is arranged in the groove of the connecting sleeve seat 3. The elastic tooth 23 is adapted to the ratchet groove 22 for one-way locking, which is convenient for adjusting the position of the connecting sleeve seat to adapt to the different heights of the patient's forehead.

[0027] The control system includes a Bluetooth module, a control module and a monitoring and reminder module. The Bluetooth module is used for wireless data transmission between the device and the user's mobile phone. The control module is used to control the winding mechanism to adjust the tightness of the upper strap 4 and the lower strap 2. The monitoring and reminder module is used to monitor the strap pre-tightening pressure and give a reminder when the pressure deviates from the preset range and control the fastening mechanism to automatically adjust. Specifically, the tightness of the upper and lower straps is controlled by controlling the forward and reverse rotation of the winding motor.

[0028] The monitoring and reminder module also includes a pressure preset submodule and a judgment and reminder submodule. The pressure preset submodule sets the pre-tightening pressure value range based on the user's mobile phone APP operation. The judgment and reminder submodule monitors the pre-tightening pressure of the upper strap 4 and the lower strap 2 when the user wears it based on the first pressure sensor 6 and the second pressure sensor 9, judges the pressure value change, controls the fastening mechanism to automatically adjust, and sends a reminder signal to the user's mobile phone.

[0029] When the non-invasive ventilator mask auxiliary fixing device is used, the pipe interface of the ventilator mask is passed through the center of the positioning frame, and then the mask is sucked and fixed by a fixing suction cup according to the triangular shape corresponding to the positioning frame and the breathing mask, and then the lower strap and the upper strap are put on the patient's head, the lower strap is positioned on the lower side of the ear, and the upper strap is positioned on the upper side of the ear and roughly parallel to the temple. Then the device is started, and the two groups of winding motors below and the group of winding motors above are controlled to rotate by the main control circuit board to tighten the lower strap and the upper strap respectively. When tightening, the patient gives real-time feedback on the wearing comfort. When the best wearing comfort is reached, the tightening of the lower strap and the upper strap is stopped, and the pressure values ​​of the first pressure sensor and the second pressure sensor at this time are set and recorded. At the same time, a certain pressure value range is relaxed up and down with this pressure value point as the center. The specific range is based on the tightness and the pressure of the feeling of wearing and falling off when the patient wears it. Then the pipeline of the ventilator is connected to the mask pipeline interface and it can be used;

[0030] When the first sensor and the second sensor detect that the pressure is higher or lower than the highest or lowest value of the set pressure value range, the main control circuit board will promptly send out a reminder message and control the winding motor to adjust the tightness of the upper or lower straps, so that the pressure values ​​of the two sets of pressure sensors are stable within the set pressure value range;

[0031] When replacing the breathing mask, loosen the lower strap and the upper strap, remove the device and then remove the pipe connected to the ventilator, peel the breathing mask from the fixed suction cup, replace it with a new breathing mask and wear it again.
