FIELD OF THE DISCLOSURE
The present disclosure relates to a ventilator system and a medical gas delivery system, and more particularly to a ventilator system and a medical gas delivery system that can be used to treat various diseases (especially for new coronary pneumonia or similar diseases).
BACKGROUND OF THE DISCLOSURE
Recently, with the rapid spread of the new coronary pneumonia epidemic, a large number of patients have been reported all over the world. For mild patients, symptoms can be controlled by using oxygen, hydroxychloroquine, remdesivir, or other medicine. When the conditions are improved, the mild patients can recuperate at home on their own. However, for moderate or severe patents, antibiotics or steroids need to be taken. Once respiratory failure occurs, use of a ventilator is required for treatment. Therefore, there is an increasing demand for the ventilator in each country.
A conventional ventilator supplies a medical gas through a gas cylinder, so as to provide an appropriate amount of oxygen to the patients and maintain respiration of the patients. However, when the ventilator is used in cooperation with the gas cylinder, the ventilator cannot be easily moved. In addition, a component of the gas cylinder is unitary, such that a component ratio of the medical gas cannot be adjusted arbitrarily.
As such, each time there is a change of the patient, the gas cylinder connected with the conventional ventilator needs to be replaced or combined with other gas cylinders in response to the disease of said patient, thereby causing use inconvenience.
In the related art, studies have shown that hydrogen can be used to treat diseases such as diabetes, hypertension, dementia, Parkinson's disease, depression, stroke, and myocardial infarction, and more particularly can be used to treat new coronary pneumonia or similar diseases. Studies have also shown that a mixed gas of hydrogen and oxygen can be used to treat new coronary pneumonia or similar diseases. Furthermore, ozone can be used to treat tuberculosis, anemia, allergic rhinitis, pneumonia, diabetes, gout, as well as new coronary pneumonia or similar diseases. While oxygen can be used to treat hypoxia, chronic obstructive pulmonary disease, or cystic fibrosis, a mixed gas of ozone and oxygen can be used to treat new coronary pneumonia or similar diseases.
In order to achieve a better therapeutic effect, multiple gases are mixed to be used as the medical gas. The conventional ventilator that is connected with the gas cylinder has problems of inconvenience in use and difficulty in adjusting the component ratio of the medical gas, and thus still has room for improvement.

In order to improve the inconvenience of using a conventional ventilator, the present disclosure provides a ventilator system and a medical gas delivery system. The ventilator system and the medical gas delivery system of the present disclosure include an electrolytic gas generation device. The electrolytic gas generation device generates gases (i.e., hydrogen, oxygen, and ozone) by water electrolysis. A medical gas can be formed through selection or combination of the gases, and can be directly provided to patients.
Hydrogen is conventionally generated by using natural gas as a raw material and through reformation. However, a system of hydrogen reformation is complicated. In addition to hydrogen, carbon monoxide (which is harmful to the human body) is also included in a final product, such that the final product is not suitable to be used as the medical gas.
Oxygen is conventionally generated by using air as a raw material and through air separation. However, a system of the air separation is complicated and noises are produced during the air separation, such that this system is not suitable for use when the patients need to rest.
Ozone is conventionally generated by applying a high voltage onto two electric plates for simulation of a lightning strike phenomenon (a corona method). When oxygen is excited by electrons, energy can be obtained and ozone can be generated after collision of oxygen. However, nitrogen oxides (which are suspected to be carcinogenic) are also generated during the corona method.
Therefore, compared to the natural gas reformation (for producing hydrogen), the air separation (for producing oxygen), and the corona method (for producing ozone) in the related art, the gases are generated through electrolysis in the present disclosure. In this way, the convenience in use is much improved. In addition, the gases produced in the present disclosure have a higher quality.
Referring to FIG. 1, FIG. 1 shows a functional block diagram of a ventilator system according to the present disclosure. The ventilator system of the present disclosure can provide hydrogen, oxygen, ozone (mixed with oxygen) or any mixed gas according to practical medical uses.
The ventilator system of the present disclosure includes a pure water supply device 10, an electrolytic gas generation device 20, a delivery device 30, an gas supply device 40, a humidifier 50, and a control unit 60.
The pure water supply device 10 is used to provide pure water W. The pure water supply device 10 includes a water supply unit 101, an ion exchange resin 102, and an impurity separation apparatus 103. Water W′ provided by the water supply unit 101 passes through the ion exchange resin 102 and the impurity separation apparatus 103, so that anion ions, cation ions, and impurities dissolved in the water can be removed and the pure water W can be obtained.
The pure water W provided by the pure water supply device 10 is electrolyzed by the electrolytic gas generation device 20, so as to generate a first gas G1 and a second gas G2. In the present embodiment, the first gas G1 is oxygen or a mixed gas of oxygen and ozone, and the second gas G2 is hydrogen.
In the present embodiment, the electrolytic gas generation device 20 is a proton exchange membrane (PEM) electrolytic gas generation device. Referring to FIG. 2, FIG. 2 shows a functional block diagram of an electrolytic gas generation device and a delivery device according to the present disclosure. Specifically, the electrolytic gas generation device 20 includes an adjustable power supply 201, an electrolysis tank 202, and separators 203, 204. The adjustable power supply 201 provides power for electrolysis. The electrolysis tank 202 is in fluid communication with the pure water supply device 10, so as to receive the pure water W provided by the pure water supply device 10. The separators 203, 204 are used to separate the gases from water in the electrolysis tank 202 generated after the electrolysis.
It should be noted that the electrolytic gas generation device 20 includes a membrane electrode assembly 205. Referring to FIG. 3, FIG. 3 shows a schematic view of a membrane electrode assembly according to the present disclosure. The membrane electrode assembly 205 includes an anode 205a, a cathode 205b, and a proton exchange membrane 205c disposed between the anode 205a and the cathode 205b. 
The membrane electrode assembly 205 is disposed in the electrolysis tank 202, and is electrically connected with the adjustable power supply 201. Specifically, the anode 205a is electrically connected with a positive electrode of the adjustable power supply 201, and the cathode 205b is electrically connected with a negative electrode of the adjustable power supply 201.
During the electrolysis, an electrolysis voltage is applied onto the membrane electrode assembly 205 by the adjustable power supply 201, so as to electrolyze the pure water W in the electrolysis tank 202. Accordingly, the first gas G1 is generated by the anode 205a, and the second gas G2 is generated by the cathode 205b. 
Specifically, when the electrolysis voltage applied by the adjustable power supply 201 is lower than a predetermined voltage, the first gas G1 is oxygen, and the second gas G2 is hydrogen. When the electrolysis voltage applied by the adjustable power supply 201 is higher than or equal to the predetermined voltage, the first gas G1 is a mixed gas of oxygen and ozone, and the second gas G2 is hydrogen. In an exemplary embodiment, the predetermined voltage is 3.0 V.
Further, when the first gas G1 contains oxygen and ozone, a concentration ratio of oxygen and ozone is also related to the electrolysis voltage. As the electrolysis voltage increases, a concentration of ozone in the first gas G1 also increases. For example, when the electrolysis voltage ranges from 3.0 V to 3.8 V, the first gas G1 contains an appropriate amount of ozone. When the electrolysis voltage ranges from 3.8 V to 10.0 V, the amount of ozone in the first gas G1 can further increase.
In addition to the electrolysis voltage, components of the first gas G1 can also be affected by the type of a catalyst layer coated on the anode 205a. When a material of the anode 205a includes iridium, iridium black, iridium dioxide, ruthenium, ruthenium oxide, platinum, platinum iridium, palladium, iridium ruthenium oxide, iridium ruthenium tantalum oxide, or any combination thereof, generation of oxygen is facilitated. Preferably, the material of the anode 205a includes iridium dioxide. When the material of the anode 205a includes tin-antimony-nickel alloy, lead dioxide, glassy carbon, boron-doped diamond, platinum-tantalum oxide, or any combination thereof, simultaneous generation of oxygen and ozone is facilitated. Preferably, the material of the anode 205a includes lead dioxide.
In the present embodiment, the material of the anode 205a and the electrolysis voltage applied onto the membrane electrode assembly 205 can be adjusted according to desired components of the first gas G1. A material of the cathode 205b can be platinum (Pt)/carbon black coated on a carbon cloth. No matter how the electrolysis voltage or the material of the cathode 205b is adjusted, the second gas G2 generated by the cathode 205b is always hydrogen.
It should be noted that hydrogen, oxygen, and ozone are able to be mixed with water vapor after the electrolysis. Therefore, the separators 203, 204 are needed for separation of the water vapor, so as to obtain the first gas G1 and the second gas G2.
Referring to FIG. 1 and FIG. 2, the delivery device 30 is in fluid communication with the electrolytic gas generation device 20. The delivery device 30 receives the first gas G1 and the second gas G2 generated by the electrolytic gas generation device 20, and the delivery device 30 is used to transport a medical gas MG. According to the first gas G1 and the second gas G2 that the delivery device 30 receives, the medical gas MG is selectively formed. In other words, the medical gas MG includes at least one of the first gas G1 and the second gas G2.
Based on the descriptions mentioned above, the first gas G1 is the mixed gas of oxygen and ozone, and the second gas G2 is hydrogen. Therefore, the medical gas MG is selected from the group consisting of: hydrogen, oxygen, a mixed gas of hydrogen and oxygen, a mixed gas of oxygen and ozone, and a mixed gas of hydrogen, oxygen, and ozone. The medical gas MG can be used to treat various diseases, which include diseases that can be treated by at least one of hydrogen, oxygen, and ozone (e.g., diseases related to new coronary pneumonia). However, the present disclosure is not limited thereto.
The delivery device 30 includes a first gas storage unit 31 and a second gas storage unit 32. The first gas storage unit 31 is in fluid communication with the electrolytic gas generation device 20 and stores the first gas G1 generated by the anode 205a. The second gas storage unit 32 is in fluid communication with the electrolytic gas generation device 20 and stores the second gas G2 generated by the cathode 205b. 
The first gas storage unit 31 includes a first storage tank 311 and a first gas sensor 312. The first gas G1 is stored in the first storage tank 311. The first gas sensor 312 is disposed in the first storage tank 311, so as to detect the first concentration detection data (such as a concentration of oxygen and ozone) in the first storage tank 311. The first gas sensor 312 is electrically connected with the control unit 60, so as to transfer the first concentration detection data to the control unit 60 at any time.
Similarly, the second gas storage unit 32 includes a second storage tank 321 and a second gas sensor 322. The second gas G2 is stored in the second storage tank 321. The second gas sensor 322 is disposed in the second storage tank 321, so as to detect second concentration detection data (such as a concentration of hydrogen) in the second storage tank 321. The second gas sensor 322 is electrically connected with the control unit 60, so as to transfer the second concentration detection data to the control unit 60 at any time.
The delivery device 30 further includes a first channel L1, a second channel L2, a confluence channel L3, a first control valve V1, and a second control valve V2. The first channel L1 is in fluid communication with the first storage tank 311, so as to deliver the first gas G1. The second channel L2 is in fluid communication with the second storage tank 321, so as to deliver the second gas G2. The confluence channel L3 is in fluid communication with the first channel L1 and the second channel L2, so as to deliver the medical gas MG. The first control valve V1 is disposed on the first channel L1 and is electrically connected with the control unit 60, so as to selectively discharge the first gas G1 through a first exit E1 or selectively deliver the first gas G1 to the confluence channel L3. The second control valve V2 is disposed on the second channel L2 and is electrically connected with the control unit 60, so as to selectively discharge the second gas G2 through a second exit E2 or selectively deliver the second gas G2 to the confluence channel L3.
The control unit 60 is electrically connected with the electrolytic gas generation device 20 and the delivery device 30. Specifically, the control unit 60 is electrically connected with the adjustable power supply 201, the first control valve V1, and the second control valve V2. In addition, the control unit 60 can receive the first concentration detection data fed back by the first gas sensor 312 and the second concentration detection data fed back by the second gas sensor 322. According to the first concentration detection data and the second concentration detection data, the control unit 60 can adjust the electrolysis voltage applied onto the membrane electrode assembly 205 by the adjustable power supply 201, and valves of the first control valve V1 and the second control valve V2 can also be controlled and turned. Therefore, the component ratio of the medical gas MG can be controlled by the control unit 60.
The pure water supply device 10, the electrolytic gas generation device 20, the delivery device 30, and the control unit 60 mentioned above are collectively referred to as the medical gas delivery system. The medical gas delivery system of the present disclosure can be applied in the ventilator system, so as to replace a gas cylinder used in the conventional ventilator.
In addition, according to practical requirements, the medical gas delivery system of the present disclosure can also be applied in an intravenous system or a rectal insufflation system. For example, when ozone is used in a treatment process, a concentration of ozone that can be inhaled through the nasal cavity has an upper limit and cannot be arbitrarily increased. Accordingly, ozone with a high concentration can be introduced into the human body via a vein or a rectum, so as to achieve a desired therapeutic effect.
In one embodiment of the present disclosure, the medical gas delivery system is used to treat new coronary pneumonia or similar diseases. Therefore, the medical gas delivery system can be applied in the ventilator system and at least one of the intravenous system and the rectal insufflation system at the same time. Hydrogen and oxygen can be injected through the ventilator system, and ozone (mixed with oxygen) can be injected through the intravenous system and/or the rectal insufflation system, so as to achieve a better therapeutic effect. In other words, the medical gas delivery system of the present disclosure can be applied in at least two of the ventilator system, the intravenous system, and the rectal insufflation system. The first gas G1 and/or the second gas G2 can be delivered to the gas supply device 40 via the delivery device 30 of the medical gas delivery system, and then can be introduced into the human body by different ways.
In an exemplary embodiment, the medical gas delivery system of the present disclosure can be simultaneously applied in the ventilator system and the intravenous system, or can be simultaneously applied in the ventilator system and the rectal insufflation system. However, the present disclosure is not limited thereto.
In addition to injecting the medical gas MG into the human body, the medical gas delivery system of the present disclosure can also be applied in extracorporeal treatments, such as autohemotherapy.
The medical gas delivery system of the present disclosure can also be applied in a blood treatment system. Specifically, blood is first drawn from a vein of the patient. When the blood is in contact with ozone, viruses and bacteria in the blood can be killed and activity of immune cells in the blood can be enhanced. Then, the processed blood is reinjected into the human body, such that a recuperative effect can be achieved through the patient's own blood.
The gas supply device 40 is in fluid communication with the delivery device 30. The gas supply device 40 is used to provide the medical gas MG that is generated by the delivery device 30. Further, the gas supply device 40 can also be used to receive exhaled gas EG from the patient P.
A detector 41 is disposed in the gas supply device 40. The detector 41 can be used to detect pressure detection data (such as a pressure value and a gas flow) of the medical gas MG and the exhaled gas EG. The detector 41 is electrically connected with the control unit 60, so as to transfer the pressure detection data to the control unit 60. According to the pressure detection data, the control unit 60 can evaluate whether the patient is spontaneously breathing and determine whether a delivery pressure value of the medical gas MG or the component ratio of the medical gas MG needs to be adjusted.
The medical gas MG is injected into the patient's lung by the gas supply device 40, and the exhaled gas EG from the patient P_is received by the gas supply device 40. Generally, the gas supply device 40 exerts a positive pressure to inject the medical gas MG into the patient's lung. Once the gas supply device 40 exerts no pressure, a pressure in the patient's lung is higher than a surrounding pressure. Then, the patient P exhales the exhaled gas EG, so that a pressure balance inside and outside the patient's body can be reached.
If the patient can spontaneously breathe after the treatment, a pressure difference will be formed between the medical gas MG and the exhaled gas EG. At this time, upon receipt of the pressure detection data, the control unit 60 determines whether an amount of the medical gas MG needs to be decreased and whether the first control valve V1 and the second control valve V2 need to be adjusted, so as to deliver the medical gas MG with an appropriate pressure value.
When spontaneous breathing efforts of the patient are low, the medical gas MG can be hydrogen, oxygen, the mixed gas of hydrogen and oxygen, the mixed gas of oxygen and ozone, or the mixed gas of hydrogen, oxygen, and ozone (which have a therapeutic effect). When the spontaneous breathing efforts of the patient are high, the component ratio of the medical gas MG can be adjusted to oxygen or the mixed gas of hydrogen and oxygen (either of which has a health care effect).
In some embodiments, the gas supply device 40 is used in cooperation with a humidifier 50. The medical gas MG can be humidified by the humidifier 50, so that a temperature of the medical gas MG is closer to a temperature of the human body and a humidity of the medical gas MG can be increased. A humidified medical gas MG* that is treated by the humidifier 50 can be provided to the patients via medical tubes for breathing purposes.
