It has a wide range of applications and is mainly used in the treatment of anaerobic infection, CO poisoning, gas embolism, decompression sickness, hypoxic-ischemic encephalopathy, brain trauma, cerebrovascular disease, etc. Hyperbaric oxygen chamber should be used with a breathing mask. The existing breathing mask has a one-way diaphragm valve at the air inlet and exhaust ports. When the patient inhales, the air pressure of the mask input trachea decreases. At this time, the silicone diaphragm deforms and decreases under negative pressure. When it is pressed down to the connecting rod, the connecting rod drives the lower end sealing plate to move downward, the valve opens, and oxygen enters the trachea; when the person stops breathing, the silicone diaphragm resets, the valve closes, and the oxygen input stops.
[0003] Existing masks have the following drawbacks: oxygen input depends on human inhalation to deform the silicone diaphragm, and a strong breath is required to open the valve to allow oxygen to pass through; patients who need treatment are physically weak and cannot sustain a course of treatment, so a solution to this oxygen input method is urgently needed.

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0028] In an embodiment of the present invention, a breathing controller is provided, the breathing controller comprising:
[0029] A control body 170, the control body is provided with an inner cavity 160, and an air inlet end 130 and an air outlet end 140 communicated with the inner cavity 160;
[0030] The control assembly 10 includes a first solenoid valve 110 and a pressure sensor 120. The pressure sensor 120 is installed on the control body and is used to sense the pressure data of the inner cavity 160. The first solenoid valve 110 is installed on the control body and is electrically connected to the pressure sensor 120. The first solenoid valve 110 is used to control the switch of the air inlet end 130; and
[0031] The pipeline 30 is used to connect the air outlet 140, the outside air and the mask 20.
[0032] According to the breathing controller in the above embodiment, when the patient inhales, the pressure sensor 120 senses that the pressure in the inner cavity 160 decreases, and the pressure sensor 120 transmits a signal to the first solenoid valve 110, and the first solenoid valve 110 opens to open the air inlet end 130 to inject oxygen. Oxygen enters the pipeline 30 through the air outlet end 140 of the control component 10, and finally enters the mask 20 through the pipeline 30 for the patient to absorb. When the patient exhales, the pressure sensor 120 senses that the pressure in the inner cavity 160 increases, and the pressure sensor 120 transmits a signal to the first solenoid valve 110, and the first solenoid valve 110 closes to stop injecting oxygen into the air inlet end 130. During the breathing process, the patient can get enough oxygen without much effort, so as to get effective treatment.
[0033] The air inlet 130 is generally connected to a hyperbaric oxygen chamber or an oxygen tank, which is generally greater than the atmospheric pressure, so oxygen cannot be continuously supplied, otherwise the patient will not be able to exhale carbon dioxide. In a traditional hyperbaric oxygen chamber controller, the patient must first overcome the pressure of the hyperbaric oxygen chamber before exhaling carbon dioxide, which can cause breathing difficulties for weak patients.
[0034] In some specific embodiments, the control component 10 further includes a second solenoid valve 150 installed on the control body 170 . The second solenoid valve 150 is controlled by the pressure sensor 120 to enable the control component 10 to communicate with the outside air.
[0035] In this embodiment, the second solenoid valve 150 plays a protective role. The pressure in the inner cavity 160 is identified by the pressure sensor 120. When the pressure in the inner cavity 160 is at a relatively high pressure state for a long time, the second solenoid valve 150 will be opened to connect the air. In this way, it can be avoided that the first solenoid valve 110 fails and causes the patient to be unable to breathe normally. The second solenoid valve 150 connects the outside air to enable the patient to breathe normally.
[0036] In some specific embodiments, the first solenoid valve 110 is a linear solenoid valve.
[0037] In this embodiment, when a person inhales, the pressure sensor 120 begins to sense that the pressure in the inner cavity 160 decreases. At this time, the signal of the pressure sensor 120 is given to the first solenoid valve 110. The first solenoid valve 110 increases the current in a linear proportion and gradually opens the air inlet end 130. Oxygen enters the human body as the person inhales.
[0038] At this time, as the pressure sensor 120 senses that the pressure in the inner cavity 160 begins to increase, after reaching a certain value or a preset certain time, the first solenoid valve 110 is closed again.
[0039] The advantage of the linear solenoid valve is that it can control the intake volume of the intake end 130. The traditional solenoid valve basically has only two states: open and closed, while the linear solenoid valve can be controlled more accurately.
[0040] In some specific embodiments, the pipeline 30 is a three-way pipeline 30, and the three-way pipeline 30 is connected to the air outlet end 140, the mask 20 and the outside air respectively.
[0041] In this embodiment, the pipeline 30 is a three-way pipeline 30, which connects the air outlet end 140, the mask 20 and the air end to each other, so that the patient inhales oxygen and exhales carbon dioxide into the air.
[0042] In some specific embodiments, the pipeline 30 further includes a first one-way valve 310 , which is used to allow the fluid to move in one direction from the air outlet 140 to the mask 20 .
[0043] When the patient inhales, the oxygen flow pushes open the first one-way valve 310, allowing oxygen to flow normally into the human body. When the patient exhales, the exhaled air flow drives the first one-way valve 310 to close the passage from the mask 20 to the control assembly 10, allowing the exhaled gas to enter the air.
[0044] In some specific embodiments, the pipeline 30 further includes a second one-way valve 320, which is used to allow one-way flow of fluid from the mask 20 to the air.
[0045] In this embodiment, when the patient exhales, the second one-way valve 320 is opened and the first one-way valve 310 is closed, so that the exhaled gas is discharged into the air. When the patient inhales, the second one-way valve 320 is closed and the first one-way valve 310 is opened, so that the concentration of oxygen can be prevented from being diluted by air.
[0046] In some specific embodiments, the first one-way valve 310 and the second one-way valve 320 are diaphragm one-way valves.
[0047] The diaphragm check valve is light, has a simple structure and is easy to install, which can save the manufacturing cost of the pipeline 30.
[0048] In some specific embodiments, the air inlet end 130 is provided with a first thread 1310 .
[0049] In this embodiment, the first thread 1310 of the air inlet 130 is convenient for connection with a hyperbaric oxygen chamber or an oxygen tank. The first thread 1310 can be an external thread or an internal thread, and the specific setting can be determined according to actual requirements.
[0050] In some specific embodiments, the gas outlet end 140 is provided with a second thread 1410 , and the pipeline 30 has a third thread 330 matching the second thread 1410 .
[0051] In this embodiment, the second thread 1410 and the third thread 330 are adapted to each other, so that the pipeline 30 is connected to the gas outlet end 140 .
[0052] It should be noted that the first thread 1310, the second thread 1410 and the third thread 330 may also be replaced by other methods, such as quick connection by magnetic attraction, or snap connection, etc.
[0053] In some specific embodiments, the pipeline 30 is made of a hose material.
[0054] In this embodiment, the pipeline 30 is made of a soft tube, which can have a high degree of freedom and facilitate the patient's movement within a certain range.
[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
