Although the product can well solve the problems, the following new problems exist:

1. the safety requirement of high-pressure oxygen is higher, and certain danger exists in household use;

2. the oxygen consumption is fast, the frequent oxygenation is time-consuming and labor-consuming, and the device is not suitable for families;

3. the use cost is high;

The passive mode refers to a mode in which the breathing apparatus 200 operates when the patient is unable to breathe spontaneously or breathing spontaneously is weak, and the patient is controlled by the machine to breathe passively.

When the spontaneous breathing of the patient is strong, the breathing apparatus 200 is in the active mode, and the operation process of the integrated machine comprises the following steps:

After the patient finishes the inspiration, before the patient shifts to the expiration, the breathing device 200 senses a signal about to expiration, starts the expiration work by itself, synchronously transmits the signal to the main control board 11, and the main control board 11 senses the signal and then controls the second electric switch 8 to be closed in real time, so that oxygen in the air storage tank 6 cannot enter the mask. Through the two processes, the oxygen generating device 100 and the breathing device 200 work synchronously, and the purpose of supplying oxygen during inspiration and stopping supplying oxygen during expiration is achieved. The pulse type oxygen supply mode of the oxygen making and breathing integrated machine is realized by circulating and reciprocating in this way.

S2: the oximeter 17 collects the blood oxygen saturation value of the patient and feeds back the blood oxygen saturation value to the main control board 11, the main control board 11 of the oxygen generating device 100 senses the signal and controls the electric control flow regulating valve 7 to output the oxygen flow, so that when the blood oxygen saturation of the patient is low, the oxygen is supplied in a large flow; when the oxygen saturation of the patient is high, the patient is supplied with oxygen at a small flow rate. Along with the pulse oxygen supply mode, the oxygen concentration of the oxygen-enriched air inhaled by the patient is ensured to be always kept within a reasonable oxygen concentration range necessary for respiratory physiology of the patient.

S3: the oxygen concentration value of the oxygen enriched air inhaled by the patient is related to the volume of the breathing mask 16, the oxygen flow rate, and the tidal volume and time of inhalation of the patient. The corresponding oxygen concentration value of the inhaled oxygen-enriched air can be obtained by knowing the volume of the breathing mask 16, the oxygen flow, the tidal volume of the patient, the inspiration time and other parameters, and is displayed on the display screen 15 for oxygen concentration monitoring.

S5: if the blood oxygen saturation value of the patient increases along with the increase of the supplied oxygen flow, ensuring that the blood oxygen saturation of the patient operates in a normal range; if the blood oxygen saturation level of the patient is not effectively increased along with the increase of the supplied oxygen flow, the problem of gas exchange in alveoli of the patient may be solved, instead of insufficient concentration of the inhaled gas, at this time, the main control board 11 controls the alarm module 18 to give an alarm, and the equipment reminds the patient of medical treatment.

When the patient does not breathe spontaneously or breathes spontaneously or is weak, the breathing apparatus 200 is in a passive mode, and the operation process of the integrated machine comprises the following steps:

t1: at this time, the breathing apparatus 200 starts the standby frequency, and helps the patient to breathe according to the set frequency, and transmits the frequency value to the main control board 11 of the oxygen generating apparatus 100 in real time, the main control board 11 sends out a signal to control the second electric switch 8 to follow the ventilation frequency of the breathing apparatus 200, and make on-off actions in real time, so that oxygen in the air storage tank 6 can be intermittently sent into the breathing mask 16 according to the preset frequency.

The specific process comprises the following steps: the breathing apparatus 200 starts the standby frequency, before the breathing apparatus enters the inspiration phase, the breathing apparatus 200 senses the signal about to breathe in, starts the inspiration work by itself, and synchronously transmits the signal to the oxygen generating apparatus 100, the main control board 11 of the oxygen generating apparatus 100 senses the signal, then the second electric switch 8 is controlled to be opened in real time, the oxygen in the air storage tank 6 is sent into the breathing mask 16, and is mixed with the air sent by the breathing apparatus 200 to form oxygen-enriched air, and the oxygen-enriched air is pressed into the patient. Before the phase of expiration is switched into, the breathing device 200 senses a signal about to exhale, starts the expiration work by itself, synchronously transmits the signal to the oxygen generating device 100, senses the signal by the main control board 11 of the oxygen generating device 100, and then controls the second electric switch 8 to be closed in real time, so that oxygen in the air storage tank 6 cannot enter the mask. Through the two processes, the oxygen generating device 100 and the breathing device 200 work synchronously, and the purpose of supplying oxygen during inspiration and stopping supplying oxygen during expiration is achieved. The pulse type oxygen supply mode of the oxygen making and breathing integrated machine is realized by circulating and reciprocating in this way.

T2: the oximeter 17 collects the blood oxygen saturation value of the patient, feeds back the blood oxygen saturation value to the main control board 11, senses the signal by the main control board 11 of the oxygen generating device 100, and controls the electric control flow regulating valve 7 to output the oxygen flow, so that when the blood oxygen saturation of the patient is low, the oxygen is supplied in a large flow manner, and when the blood oxygen saturation of the patient is high, the oxygen is supplied in a small flow manner. Along with the pulse oxygen supply mode, the oxygen concentration of the oxygen-enriched air inhaled by the patient is ensured to be always kept within a reasonable oxygen concentration range necessary for respiratory physiology of the patient.

T4: the blood oxygen saturation value of the patient increases along with the increase of the supplied oxygen flow, so that the blood oxygen saturation of the patient is ensured to run in a normal range; if the blood oxygen saturation level of the patient is not effectively increased along with the increase of the supplied oxygen flow, the problem of gas exchange in alveoli of the patient may be solved, instead of insufficient concentration of the inhaled gas, at this time, the main control board 11 controls the alarm module 18 to give an alarm, and the equipment reminds the patient of medical treatment.

In a special case, when the breathing apparatus 200 fails, that is, when the breathing apparatus 200 stops working, the main control board 11 of the oxygen generating apparatus 100 records the breathing frequency before the breathing apparatus 200 fails in real time. After receiving the instruction of the fault of the breathing device 20, the main control board 110 controls the first electric switch 10 to be normally opened, controls the regulating module 9 according to the last recorded respiratory frequency, tidal volume, respiratory pressure, inspiration time and other parameters, reduces the pressure and throttles the compressed air at the outlet of the air compressor 1 in the oxygen generating device 100 according to the respiratory waveform required by the patient, provides air with certain pressure and flow which meets the respiratory intensity of the patient, meets the basic respiratory requirement of the patient, and reports and repairs the patient through the alarm module 18.
