All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1:

[0039] AsFigures 1-3 As shown in Figures 1-3 , an embodiment of the present invention provides a portable intelligent pressure regulating device for non-invasive ventilation masks used in respiratory care, including a mask 1. At the front end of the mask 1, there is an adjustment module 2 for adjusting the ventilation volume. The adjustment module 2 includes an adjustment tube 202. A connecting plate 201 is fixedly connected to the side wall of the adjustment tube 202. The inner side wall of the adjustment tube 202 is rotatably connected to a rotating tube 206 at the rear side. The side wall of the rotating tube 206 is rotatably connected to an installation tube 204 at the rear side. The rear end of the installation tube 204 is fixedly connected to the front end of the mask 1. The front end of the adjustment tube 202 is fixedly connected to an air inlet tube 3. A monitoring device 4 for monitoring and adjusting the ventilation volume is also provided on the inner side wall of the adjustment module 2.

[0040] A fixing frame 205 is fixedly connected to the middle of the inner side wall of the rotating tube 206. A screw 207 is fixedly connected to the middle of the front end of the fixing frame 205. Sleeve tubes 203 are respectively fixedly connected to both sides of the front end of the fixing frame 205. Slide rods 2012 are respectively slidably connected to the inner side walls of the two sleeve tubes 203. A slide plate 208 is threadedly connected to the side wall of the screw 207. A spring 2011 is fixedly connected to the front end of the slide plate 208. A conical tube 209 is fixedly connected to the inner side wall of the adjustment tube 202 at the front side. A sealing plug 2010 is slidably connected to the inner side wall of the conical tube 209. By setting the adjustment module 2, the adjustment module 2 is provided at the front end of the mask 1. The air supply device is connected to the whole device by using the air inlet tube 3, and the mask 1 is covered on the patient's face. By rotating the rotating tube 206, the fixing frame 205 is rotated, so that the fixing frame 205 drives the screw 207 to rotate. At the same time, since the screw 207 and the slide plate 208 are threadedly connected, the rotation of the screw 207 can make the slide plate 208 rotate along the screw 207, thereby gradually releasing the pressure formed by the spring 2011 on the sealing plug 2010, so that the intake air volume when the gas enters the mask 1 through the adjustment tube 202 gradually increases, thereby realizing the adjustment of the ventilation volume pressure, effectively and quickly adjusting the size and rate of the ventilation volume, and improving the treatment effect on the patient.

[0041] The rear end of the connecting plate 201 is fixedly connected to the upper position of the front end of the mask 1. The front ends of the two slide rods 2012 are respectively slidably connected to both sides of the rear end of the slide plate 208. The other ends of the springs 2011 are respectively fixedly connected to the rear end of the sealing plug 2010. The inner side walls of the adjustment tube 202 and the installation tube 204 are respectively adapted to the side wall of the rotating tube 206. The spring 2011 is sleeved on the side wall of the screw 207.

[0042] Working principle: An adjustment module 2 is provided at the front end of the mask 1. The air supply device is connected to the whole device by an air inlet pipe 3, and the mask 1 is covered on the patient's face. By rotating the rotating pipe 206, the fixing frame 205 rotates, so that the fixing frame 205 drives the screw 207 to rotate. At the same time, since the screw 207 is threadedly connected to the slide plate 208, the rotation of the screw 207 can make the slide plate 208 rotate along the screw 207, thereby gradually relieving the pressure formed by the spring 2011 on the sealing plug 2010, so that the air intake volume when the gas enters the mask 1 through the adjustment pipe 202 gradually increases, thereby realizing the adjustment of the ventilation volume pressure.

[0043] Embodiment 2:

[0044] As Figures 4-7 shown, an embodiment of the present invention provides a portable non-invasive ventilation mask pressure intelligent adjustment device for respiratory care. The monitoring device 4 includes:

[0045] A pressure monitoring module for real-time monitoring of the air pressure change in the non-invasive ventilation mask, including a pressure sensor and respiratory monitoring. The pressure sensor selects a piezoelectric sensor, which converts pressure into an electrical signal using the piezoelectric effect and is installed in the air supply pipeline for monitoring the gas pressure entering the mask interior. The respiratory monitoring is used to real-time monitor the patient's breathing frequency when using the mask, adjust the air supply volume according to the patient's breathing depth, and automatically adjust the air supply pressure according to the patient's breathing condition and air pressure change to ensure the stability and comfort of the air pressure in the mask. Through the real-time monitoring of the pressure sensor and the control unit, the system can promptly detect abnormal air pressure and remind medical staff through visual and auditory alarm devices to ensure that patients can be quickly treated when breathing problems occur. This rapid response mechanism greatly shortens the time for problem discovery and handling and reduces the risks faced by patients due to abnormal air pressure.

[0046] A control module for controlling the whole device.

[0047] An alarm device for giving timely alarms in different situations, including visual alarm, auditory alarm, and alarm level.

[0048] An adjustment device for adjusting the air intake volume of the mask and also performing self-check on the mask before use, including an adjustment module 2 and a self-check function.

[0049] The visual alarm includes an LED indicator light, and the operating status of the equipment is judged according to the color change of the LED indicator light. The auditory alarm includes a buzzer, and the volume of the buzzer is adjusted according to the ambient noise level to ensure that the alarm sound can be heard even in a noisy environment. The system adopts a multi-level alarm mechanism, including primary visual alarms and secondary auditory alarms. This multi-level alarm method ensures that medical staff can receive alarm information in a timely manner in various environments, effectively reducing the possibility of missed alarms and false alarms, and improving the reliability of the system.

[0050] The self-check function is used to perform self-checks regularly to ensure that all parts of the system are working normally.

[0051] In some cases, the pressure value measured by the pressure sensor needs to be converted from cm H2O to Pa in order to be unified with other systems or standards, and the average pressure over a period of time is calculated based on the pressure change to assess the patient's overall respiratory status. The following formula is used:

[0052] Pressure unit conversion:

[0053] P(Pa)=P(cm H2O)×98.0665

[0054] Pressure average calculation:

[0055]

[0056] The control module is responsible for receiving data from the pressure sensor and making judgments based on a preset pressure threshold. The control module uses a programmable controller and can achieve real-time monitoring and intelligent regulation of air pressure.

[0057] Workflow: Install the pressure sensor on the air supply pipe or the mask body to ensure that the sensor is in good contact with the air flow path, connect the output line of the pressure sensor to the analog signal interface of the control unit, and set the upper and lower limits of the air pressure through the setting interface of the control unit according to the patient's needs. The rotation of the screw 207 can make the slide plate 208 rotate along the screw 207, thereby gradually releasing the pressure formed between the spring 2011 and the sealing plug 2010, so that the air intake volume when the gas enters the mask 1 through the regulating tube 202 gradually increases, thereby realizing the regulation of the ventilation volume pressure. When the air pressure is abnormal, the LED indicator light will light up and the display screen will display the alarm information. The alarm type can be identified according to the color of the indicator light and the information on the display screen. The buzzer or bell will emit alarm sounds of different frequencies and tones to alert medical staff. At this time, take appropriate measures according to the alarm type, and after confirming that the fault has been eliminated, press the reset button on the control unit to release the alarm state.

[0058] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
