Detailed Description
The technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments obtained by a person skilled in the art without any creative effort based on the technical solutions provided by the embodiments of the present invention belong to the protection scope of the present invention.
Example 1
In order to solve the technical problems that the transportation and carrying of the respirator are inconvenient and the oxygen supply amount cannot be controlled due to the fact that the respirator adopts an oxygen bottle, as shown in fig. 1, the embodiment discloses an automatic control respirator for supplying oxygen by multiple oxygen candles, which comprises an oxygen inhalation mask 10 and an oxygen supply device 20. The oxygen inhalation mask 10 is connected with a hard gas storage bag 30 and a circulating pump 40 through gas pipes to form an oxygen therapy circulation passage. A carbon dioxide absorbing device 31 and a pressure sensor 32 are provided in the rigid gas storage bag 30. The oxygen supply device 20 comprises a processor 21, a container 23 with a plurality of oxygen candles 22 arranged therein, and an electronic initiator 24 sequentially connected with the oxygen candles 22. The receiving body 23 is communicated with the gas storage bag 30 through a gas conveying pipe; the electronic initiator 24, the processor 21 and the pressure sensor 32 are electrically connected in sequence.
Wherein the oxygen candle 22 is formed by evenly mixing and pressing oxygen-rich sodium chlorate and catalyst. Sodium chlorate releases a large amount of oxygen at about 300 ℃, and after the oxygen is released, the remaining solid matter is common sodium chloride industrial salt containing impurities. The oxygen candle always keeps the solid form unchanged before and after the oxygen preparation process, releases the stored oxygen element, and does not have the pre-storage and high pressure of oxygen in the whole process of use, so the oxygen candle belongs to a safe oxygen source.
Oxygen generated by the oxygen candle 22 is stored in the gas storage bag 30 through the gas pipe, and then enters the oxygen inhalation mask 10 through the circulating pump 40, the gas exhaled by the user is exhaled from the gas outlet of the oxygen inhalation mask 10, and the pressure sensor 32 detects the pressure of the exhaled gas. When the air pressure is lower than the set value of the processor 21, for example, the air pressure is lower than 500Pa, the processor 21 controls the electronic initiator 24 to initiate the oxygen candle 22, the oxygen candle 22 generates oxygen to increase the air pressure in the air storage bag 30, that is, the air pressure in the oxygen inhalation mask 10 is increased; when the air pressure is higher than the set value of the processor 21, if the air pressure is higher than 500Pa, the processor 21 stops the electronic initiator 24 from initiating the oxygen candle 22, and the air pressure in the oxygen mask 10 is reduced to the set value, thereby achieving the effect of maintaining the air pressure in the oxygen mask 10. When the oxygen mask works, the circulating pump 40 circularly conveys oxygen in the gas storage bag 30 into the oxygen mask 10, so that the oxygen in the mask 10 reaches a constant value, and discomfort of a user is avoided.
When stopping is needed, the processor 21 is closed, and the oxygen candle 22 is stopped to be triggered; when the user needs to use the device again, the processor 21 is turned on to see the remaining use time, and then the device is started.
Because the human body can produce carbon dioxide in the breathing process, in order to improve the oxygen utilization rate of the respirator, the carbon dioxide absorber 31 arranged in the gas storage bag 30 can absorb carbon dioxide exhaled by the human body, and the content of the carbon dioxide in the gas storage bag 30 is reduced.
This embodiment adopts oxygen candle 22 to carry out the oxygen suppliment as the oxygen source, has improved the portability that the respirator transported and carried, disperses into a plurality of independent oxygen candles 22 with the oxygen source, makes oxygen candle 22 can initiate alone through pressure sensor 32 and treater 21 for the volume of supplying oxygen of respirator can be adjusted as required, reaches the technological effect of automatic control oxygen supply volume.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
