In the critical care medicine department, some patients with damaged respiratory tracts need external assistance to restore breathing, and they also need breathing training to help them restore their respiratory function.

[0003] However, in the prior art, the respiratory recovery assist device still has some shortcomings: 1. Some respiratory recovery devices cannot monitor the patient's respiratory status, especially for patients in coma, it is difficult to grasp the patient's respiratory status, causing medical staff to frequently pay attention to the patient's status; 2. Some respiratory recovery devices cannot adjust the oxygen supply according to the patient's breathing intensity. It is also difficult to adjust the intensity of exhalation training, resulting in low efficiency of respiratory recovery. 3. Some breathing recovery devices are difficult to assist patients in training nasal inhalation and mouth exhalation, and are less practical. Summary of the invention

[0004] In order to solve the above-mentioned existing problems, the present invention provides a respiratory recovery assistance device for critical care medicine. By utilizing the air pressure principle in combination with flexible materials, an inflatable sensing chest auxiliary component is provided. The up and down floating of the patient's chest is indirectly reflected through the up and down floating of the floating block, thereby achieving the technical effect of monitoring the patient's respiratory status, which is also applicable to patients in a coma. By utilizing the electromagnetic principle, a respiratory assistance mask component is provided to force the patient to perform nasal inhalation and mouth exhalation breathing training, thereby better helping the patient to recover breathing and enhance vital capacity. At the same time, by changing the current flowing through the first electromagnetic block and the second electromagnetic block, the electromagnetic repulsion of the first blocking block and the second blocking ball is adjusted, thereby adjusting the oxygen supply and the exhalation intensity. The operation is simple and the use is convenient.

[0005] To achieve the above-mentioned objectives, the technical scheme adopted by the present invention is as follows: A respiratory recovery assistance device for critical care medicine provided by the present invention comprises an adjusting and fixing seat mechanism, an upper end of the adjusting and fixing seat mechanism is provided with an inflatable induction chest auxiliary component, an outer side of the adjusting and fixing seat mechanism away from the inflatable induction chest auxiliary component is provided with a magnetically controlled adjustable oxygen supply component, the inflatable induction chest auxiliary component is movably arranged above the magnetically controlled adjustable oxygen supply component, and the side wall of the magnetically controlled adjustable oxygen supply component is connected to a respiratory assistance cover component, wherein the inflatable induction chest auxiliary component comprises a pressure plate, an induction airbag and an air-filling induction mechanism, the pressure plate is horizontally arranged at the upper end of the adjusting and fixing seat mechanism, the induction airbag is arranged at the lower part of the pressure plate, the air-filling induction mechanism is arranged at the upper part of the pressure plate, and the air-filling induction mechanism is connected to the induction airbag.

One side of the floating block penetrates the side wall of the sliding column and slides on the sensing panel. The sliding column adopts a transparent plastic tube, the floating block adopts a lightweight plastic, and the sensing airbag adopts an inelastic flexible rubber material. When in use, adjust the compression plate to a position where its lower end face is 10-15cm away from the patient's chest, then start the first air pump to inflate the sensing airbag, and the lower end face of the sensing airbag adaptively fits the patient's chest. After the gas fills the sensing airbag between the compression plate and the patient's chest, the floating block is lifted up. When the floating block is observed to float up to the middle position in the sliding column, the first air pump is stopped. Since the sensing airbag has no elasticity, at this time, when the patient breathes, the up and down floating of the chest can be indirectly reflected by the up and down floating of the floating block. When the patient exhales, the chest sinks, and the space between the chest and the compression plate becomes larger, and the sensing airbag is inflated. As the gas in the airbag increases, the floating block moves down; when the patient inhales, the chest cavity rises, the space between the chest cavity and the pressure plate becomes smaller, the gas in the induction airbag is squeezed into the sliding column, and the floating block moves up; start the controller, the sensing panel records the amplitude of the floating block sliding up and down, and sets the floating threshold in advance. When the patient has shortness of breath or difficulty breathing, the floating block will shake violently or stop.

Finally, open the valve of the external oxygen tank and connect it to the first ventilation valve; when the patient inhales, that is, when the floating block moves upward, the induction panel emits a signal at the critical point when the floating block is about to move upward. The third electromagnetic block is energized to generate magnetism. At this time, the magnetic poles of the third electromagnetic block and the magnetic sheet are different. The third electromagnetic block adsorbs the magnetic sheet, and the nose patch pulls the patient's nose wings open, so that the patient can inhale oxygen better. The oxygen enters the patient's nasal cavity through the filtration and humidification of the filter cotton. At this time, the second blocking ball blocks the third connecting pipe under the action of gravity, and the patient cannot inhale through the mouth and can only inhale through the nasal cavity; when the patient exhales, that is, when the floating block moves downward, the induction panel emits a signal at the critical point when the floating block is about to move downward, so that the current flowing through the third electromagnetic block is reversed.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The present invention provides a respiratory recovery assist device for critical care medicine. It uses the air pressure principle combined with flexible materials to set an inflatable sensing chest auxiliary component. The up and down floating of the patient's chest is indirectly reflected by the up and down floating of the floating block. The sensing panel records the amplitude of the up and down sliding of the floating block, and the floating threshold is pre-set. When the patient has shortness of breath or difficulty breathing, the floating of the floating block will shake violently or stop. At this time, the external alarm sounds an alarm to notify medical staff to provide treatment in time, thereby achieving the technical effect of monitoring the patient's respiratory status. It is also applicable to patients in coma, reducing the workload of medical staff; 2. Using the electromagnetic principle, the breathing assist mask assembly is set up. When the patient inhales or exhales, the magnetic poles between the third electromagnetic block and the magnetic sheet are controlled to open or close the patient's nasal cavity, forcing the patient to perform nasal inhalation and mouth exhalation breathing training, which better helps the patient recover breathing and enhances vital capacity; 3.

When the lower end surface of the pressing plate 21 is 10-15 cm away from the patient's chest, this distance is smaller than the distance from the lower end surface of the sensing airbag 22 to the lower end surface of the pressing plate 21 after it is fully inflated. The pressing rod 17 is restored to fix the position of the pressing plate 21. Then, the first air pump 23 is started to inflate the sensing airbag 22. The lower end surface of the sensing airbag 22 adaptively fits the patient's chest. After the gas fills the sensing airbag 22 between the pressing plate 21 and the patient's chest, the floating block 273 is lifted up. When the floating block 273 is observed to float to the middle position in the sliding column 271, the first air pump 23 is stopped. , since the sensing airbag 22 has no elasticity, at this time, when the patient breathes, the up and down floating of the chest cavity can be indirectly reflected by the up and down floating of the floating block 273. When the patient exhales, the chest cavity sinks, the space between the chest cavity and the pressing plate 21 becomes larger, the gas in the sensing airbag 22 increases, and the floating block 273 moves down; when the patient inhales, the chest cavity rises, the space between the chest cavity and the pressing plate 21 becomes smaller, the gas in the sensing airbag 22 is squeezed into the sliding column 271, and the floating block 273 moves up; start the controller, the sensing panel 272 records the amplitude of the up and down sliding of the floating block 273, and pre-sets the floating threshold. When the patient has shortness of breath or difficulty breathing, the floating of the floating block 273 will shake violently or stop. At this time, the external alarm sounds an alarm, and promptly notifies the medical staff to provide treatment, thereby achieving the technical effect of monitoring the patient's respiratory state, which is also applicable to patients in a coma.

[0026] After adjusting the induction airbag 22, remove the breathing assistance mask assembly 4, first stick the nose patch 48 with the magnetic sheet 49 embedded therein to the two sides of the patient's nose, pull out the flat tube 43, put it into the patient's mouth and bite it with the teeth, then pull open the elastic rope 42 and put it on the patient's head to put on the mask 41 for the patient, observe the distance between the third electromagnetic block 47 and the magnetic sheet 49 through the mask 41, turn the adjustment bolt 46 to adjust the distance between the third electromagnetic block 47 and the magnetic sheet 49 to about 0.5-1cm, finally open the external oxygen tank valve and connect it to the first ventilation valve 35; start the controller, when the patient inhales, that is, when the floating block 273 moves up, the induction panel 272 sends a signal at the critical point when the floating block 273 is about to move up, and the third electromagnetic block 47 is energized to generate magnetism. At this time, the magnetic poles of the third electromagnetic block 47 and the magnetic sheet 49 are different, and the third electromagnetic block 47 absorbs the magnetic sheet 49, and the nose patch 48 pulls the patient's nose to open, so that oxygen can be better inhaled, and oxygen passes through The filtration and humidification of the filter cotton 33 enters the patient's nasal cavity through the second ventilation valve 361, the first connecting pipe 362, the ventilation cavity 363, the second connecting pipe 364 and the inhalation pipe 44. At this time, the second blocking ball 374 blocks the third connecting pipe 371 under the action of gravity, and the patient cannot inhale through the mouth but can only inhale through the nasal cavity; when the patient exhales, that is, when the floating block 273 moves downward, the sensing panel 272 sends a signal at the critical point when the floating block 273 is about to move downward, so that the air flowing through the third electromagnetic block 47 When the current is reversed, the magnetic poles of the third electromagnetic block 47 and the magnetic sheet 49 are the same. The third electromagnetic block 47 pushes the magnetic sheet 49 through the electromagnetic repulsion, thereby pressing the patient's nostrils, forcing the patient to exhale through the mouth. The exhaled gas is blown into the exhalation training chamber 372 through the exhalation tube 45 and the third connecting tube 371, blowing up the second ball 374, thereby training the patient's vital capacity. By using the electromagnetic principle, the patient is forced to perform nasal inhalation and mouth exhalation breathing training, which better helps the patient to restore breathing and enhance vital capacity.

[0027] When the patient is performing breathing training through the nose and mouth, the oxygen supply and the exhalation intensity can be adjusted according to the patient's breathing state; when the oxygen supply needs to be adjusted, the first electromagnetic block 365 is energized to generate magnetism, and the magnetic poles of the first electromagnetic block 365 and the first blocking block 366 are the same. The first blocking block 366 moves upward under the action of the electromagnetic repulsive force, so that the distance between the hypotenuse of the first blocking block 366 and the inner wall of the ventilation cavity 363 is reduced, thereby narrowing the channel for circulating oxygen, thereby reducing the patient's oxygen intake in a single breath; similarly, when the exhalation intensity needs to be adjusted, the second electromagnetic block 373 is energized The second electromagnetic block 373 generates magnetism, and the magnetic poles of the second blocking ball 374 are the same. The second blocking ball 374 is subjected to the electromagnetic repulsion of the second electromagnetic block 373, so that when the patient exhales, he not only needs to overcome the gravity of the second blocking ball 374, but also needs to use stronger blowing to overcome part of the electromagnetic repulsion to blow up the second blocking ball 374; by changing the current flowing through the first electromagnetic block 365 and the second electromagnetic block 373, the electromagnetic repulsion of the first blocking block 366 and the second blocking ball 374 can be adjusted, thereby adjusting the oxygen supply and the exhalation intensity, which is simple to operate and convenient to use.

[0028] When the patient is in a coma and has no consciousness of spontaneous breathing, external intervention in breathing is required. The second air pump 24 is turned on to inflate the contraction tube 25, the contraction tube 25 extends, and the auxiliary compression plate 26 squeezes the chest cavity. Then the second air pump 24 evacuates air, and the contraction tube 25 is reset. The second air pump 24 cyclically inflates and deflates, and the auxiliary compression plate 26 intermittently presses the patient's chest cavity to strengthen the movement of the patient's diaphragm and assist the patient in breathing.

[0029] It is worth noting that the operation settings of the controller and the application of the sensing panel 272 are all existing technologies and will not be described in detail here.

[0030] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.
