Description

Technical Field

[0001] The present invention relates to the field of respiratory assistance, and more specifically, to a respiratory rehabilitation assistance device for critically ill patients in intensive care medicine. Background Art

[0002] Critically ill patients in intensive care medicine usually suffer from respiratory dysfunction due to respiratory failure or other diseases and are unable to breathe effectively on their own. In response, respiratory rehabilitation assistance devices have been widely used clinically to help patients maintain their lives. Existing respiratory rehabilitation assistance devices mainly include mechanical ventilators, high-flow nasal positive pressure ventilation (HFNC), and continuous positive pressure ventilation (CPAP). These devices have their own advantages and disadvantages. For example, mechanical ventilators have strong adjustment functions, but cause strong discomfort during use. HFNC and CPAP are more comfortable, but have limited ability to control the pulmonary infiltration pressure of patients.

[0003] In response to these problems, in recent years, many researchers have been committed to developing safer, more effective, and more comfortable respiratory rehabilitation assistance devices. Some researchers have explored new ideas such as sonic airflow-assisted breathing, pulmonary function training devices, and the use of artificial intelligence technology to dynamically adjust ventilation parameters. At the same time, some researchers have also focused on incorporating comfort into device design, such as reducing respiratory resistance and improving the wearing experience.

[0004] However, existing respiratory rehabilitation assistance devices still have deficiencies in specific groups of critically ill patients. For example, for some patients with special diseases such as epilepsy patients or special physiological characteristics, existing devices are unable to quickly clean the saliva and sputum spit out by patients during use. To prevent patients from choking on the liquid, it is necessary to stop working, clean the liquid, and then resume assisted breathing. Therefore, developing a respiratory rehabilitation assistance device for critically ill patients to improve the treatment effect and reduce the adverse reactions of patients remains an important topic. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a respiratory rehabilitation assistance device for critically ill patients, which can automatically clean the sputum and saliva of patients during assisted breathing without stopping work for cleaning.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A respiratory rehabilitation assistance device for critically ill patients, comprising a balloon component. In the middle of one side of the balloon component, a first pipe is fixedly installed. At the upper end of the side of the balloon component close to the first pipe, a third pipe is fixedly installed.

At the end of the second pipe away from the transfer piece, a mask component is fixedly installed. On the side of the balloon component away from the first pipe, an oxygen storage bag and an oxygen delivery pipe are installed;

[0008] The balloon component includes a first balloon. At the central position inside the first balloon, a second balloon is provided. At both ends of the second balloon, a first connection housing and a second connection housing are integrally formed respectively. The first pipe is fixedly installed on the first connection housing. A liquid storage cavity is formed between the inside of the first balloon and the second balloon. The inside of the second balloon has an oxygen supply cavity. The third pipe is communicated with the liquid storage cavity, and the first pipe is communicated with the oxygen supply cavity.

[0009] Furthermore, the transfer piece includes a transfer housing. At the upper end inside the transfer housing, two symmetrically arranged first duckbill soft pieces are fixedly installed. The first duckbill soft pieces are used to make the gas inside the first pipe can only enter the first transfer chamber unidirectionally.

The conical rubber ring divides the inside of the transfer housing into a first transfer chamber and a second transfer chamber. The first pipe is communicated with the first transfer chamber, and the third pipe is communicated with the second transfer chamber.

[0010] Furthermore, the top end of the second pipe extends into the inside of the transfer housing. The lower end of the conical rubber ring is sleeved on the upper end of the second pipe. At the lower end of the first balloon, an output component for draining liquid is fixedly installed. The output component is communicated with the liquid storage cavity. A first connection hose is fixedly connected between the third pipe and the mask component. A second connection hose is fixedly connected between the mask component and the output component.

[0011] Furthermore, at the middle position inside the second connection housing, a ventilation plate is fixedly installed. A plurality of uniformly distributed ventilation holes are opened on the ventilation plate. On the side of the second connection housing close to the second balloon, a sealing plate is provided. On the side of the sealing plate close to the ventilation plate, a plurality of uniformly distributed stabilizing rods are fixedly installed. The stabilizing rods are slidably clamped on the ventilation plate. A plurality of uniformly distributed return springs are fixedly connected between the ventilation plate and the sealing plate. The ventilation plate divides the inside of the second connection housing into a first chamber and a second chamber.

[0012] Further, on the side of the second connection housing away from the second balloon, a first connection pipe and a second connection pipe are fixedly installed. A threaded cylinder is fixedly installed on the first connection pipe, and a plug connector is fixedly installed on the second connection pipe. The oxygen storage bag is sleeved outside the threaded cylinder through a threaded fit, and the oxygen delivery pipe is sleeved outside the plug connector.

[0013] Further, the mask component includes a sealing cover body. At the bottom end of the sealing cover body, a surrounding pipe is fixedly installed. At the upper position of the inner circle of the surrounding pipe, a plurality of uniformly distributed liquid leakage grooves are provided. At the lower end of one side of the outside of the surrounding pipe, a first socket is fixedly installed. At the lower end of the side of the outside of the surrounding pipe away from the first socket, a second socket is fixedly installed. Both the first socket and the second socket are communicated with the inside of the surrounding pipe.

[0014] Further, the output component includes an output pipe. At the top end of the output pipe, a first connection joint is fixedly installed. Inside the first connection joint, there are two symmetrically arranged second duckbill soft pieces. At the bottom end of the output pipe, a second connection joint is fixedly installed.

[0015] Further, one end of the first connection hose is detachably sleeved outside the first socket, and the end of the first connection hose away from the first socket is fixedly connected to one end of the third pipe close to the transfer housing.

[0016] Further, one end of the second connection hose is detachably sleeved outside the second socket, and the end of the second connection hose away from the second socket is fixedly connected to the output pipe.

[0017] Further, the inside of the first connection pipe and the second connection pipe has a ventilation groove. In the middle of the ventilation groove, a spherical valve core is connected by a spherical connection. A central groove body is provided in the middle of the spherical valve core. On both the first connection pipe and the second connection pipe, a turning handle is rotatably installed, and the turning handle is fixedly installed on the corresponding spherical valve core.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By setting the first balloon and the second balloon, the device can absorb the liquid ejected by the patient while assisting breathing and store it in different chambers. It can not only prevent liquids such as sputum from contaminating the device, but also guide the liquid to be discharged without stopping the assisted breathing, which has a better assisting effect on the patient and is more suitable for emergency patients.

[0020] 2. When the device inputs air to the patient, the oxygen delivery tube can automatically inflate the oxygen storage bag, store oxygen when blowing air to the patient, and then the device inhales air independently, making the oxygen input more stable. The oxygen storage bag can also provide additional oxygen supply when the oxygen supply of the oxygen delivery tube is unstable, making the device safer and more stable during use.

[0021] 3. By setting an output component, when continuously pressing the balloon component, the waste liquid in the liquid storage cavity can be continuously discharged, realizing the cyclic output of the liquid. Even for patients such as drowning patients who will discharge a large amount of liquid, there is no need to repeatedly stop working and then clean up. It can achieve cyclic cleaning along with the auxiliary work and can better treat the patient.

[0022] 4. By setting a spherical valve core, the oxygen content of the gas supplied by the device can be quickly changed, thereby improving the ability of assisted breathing and making the device more efficient during use.

[0023] 5. By setting a first connecting pipe and a second connecting pipe, the device can quickly clean all components of the entire device after use, with fast and thorough cleaning.

[0024] 6. By setting a second pipe, the device has higher safety during use, preventing damage to the patient's lungs caused by excessive blowing or excessive inhalation and preventing the occurrence of lung complications. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 8 , a respiratory rehabilitation assistance device for critically ill patients, including a balloon component 1, a first pipe 2 is fixedly installed in the middle of one side of the balloon component 1, a third pipe 21 is fixedly installed at the upper end of the side of the balloon component 1 close to the first pipe 2, one end of the first pipe 2 away from the balloon component 1 is fixedly installed with a transfer piece 3 for controlling the gas flow direction, one end of the first pipe 2 away from the balloon component 1 is fixedly installed on the side surface of the transfer piece 3, a second pipe 4 is fixedly installed at the lower end of the transfer piece 3, one end of the second pipe 4 away from the transfer piece 3 is fixedly installed with a mask component 5, an oxygen storage bag 8 and an oxygen delivery pipe 9 are installed on the side of the balloon component 1 away from the first pipe 2, the balloon component 1 includes a first balloon 11, and an output component 7 for draining liquid is fixedly installed at the lower end of the first balloon 11, and a second balloon 12 is arranged at the central position inside the first balloon 11.

[0037] In actual use, by squeezing the balloon component 1, oxygen can be pumped into the patient's body, thereby assisting the patient in breathing. After losing the pressing effect on the balloon component 1, the balloon component 1 can elastically rebound and return to its original state. When the balloon component 1 returns to its original state, it can generate negative pressure to assist the patient in exhaling, and at the same time, it can suck out the blocked sputum or other liquids in the patient's body. In the emergency department, some patients may have their airways blocked by aspirated liquid or other foreign objects, resulting in weak breathing or even inability to breathe independently. In this case, respiratory rehabilitation assistance is required for the patient. However, during use, it is easy to be contaminated and blocked by the sputum, saliva, water or other liquids in the patient's body during assisted breathing, so continuous cleaning is needed. When dealing with some critically ill patients, immediate respiratory rehabilitation assistance is required, and intubation cannot be performed, which leads to the liquid and sputum in the patient's body contaminating and blocking the assisted device. By setting the first balloon 11 and the second balloon 12, this device can absorb the liquid ejected by the patient while assisting breathing and store it in different chambers. This not only prevents liquids such as sputum from contaminating the device, but also can drain the liquid without stopping assisted breathing, resulting in a better assisting effect on the patient and being more suitable for emergency patients.

[0038] At both ends of the second balloon 12, a first connection housing 13 and a second connection housing 14 are integrally formed respectively. The first pipeline 2 is fixedly installed on the first connection housing 13. A liquid storage chamber 101 is formed between the inside of the first balloon 11 and the second balloon 12. The inside of the second balloon 12 has an oxygen supply chamber 102. The third pipeline 21 communicates with the liquid storage chamber 101, and the first pipeline 2 communicates with the oxygen supply chamber 102.

[0039] When the balloon component 1 is pressed, positive pressure is generated inside both the liquid storage cavity 101 and the oxygen supply cavity 102. At this time, the gas and liquid inside the liquid storage cavity 101 will be discharged through the output component 7, while the gas inside the oxygen supply cavity 102 will be output to the transfer part 3 through the first pipeline 2. The transfer part 3 will then transport the gas to the mask component 5 through the second pipeline 4. The mask component 5 is pressed against the patient's mouth, thereby realizing the pumping of gas into the patient's body. At the same time, the waste liquid and waste gas inside the liquid storage cavity 101 are discharged through the output component 7. When the hand is released, at this time, the first balloon 11 and the second balloon 12 undergo elastic rebound, generating negative pressure in the liquid storage cavity 101 and the oxygen supply cavity 102. The liquid storage cavity 101 sucks air from the inside of the transfer part 3 through the third pipeline 21. At this time, the transfer part 3, the second pipeline 4, and the mask component 5 are connected, causing the patient's exhaled air to enter the inside of the liquid storage cavity 101 along the third pipeline 21. If the patient coughs or spits out phlegm during exhalation, it will enter the inside of the third pipeline 21 along with the negative pressure and finally be sucked into the inside of the liquid storage cavity 101. When the second balloon 12 rebounds elastically and returns to its original state, the oxygen supply cavity 102 sucks the oxygen inside the oxygen delivery tube 9 and the oxygen storage bag 8. When the second balloon 12 is pressed, the oxygen supply of the oxygen storage bag 8 and the oxygen delivery tube 9 stops, which can prevent excessive oxygen supply.

[0040] The transfer part 3 includes a transfer housing 31. Two symmetrically arranged first duckbill soft pieces 32 are fixedly installed at the upper end inside the transfer housing 31. The first duckbill soft pieces 32 are used to make the gas inside the first pipeline 2 can only enter the first transfer chamber 34 unidirectionally. A conical rubber ring 33 is fixedly installed in the middle of the transfer housing 31. The conical rubber ring 33 divides the inside of the transfer housing 31 into a first transfer chamber 34 and a second transfer chamber 35. The first pipeline 2 is connected to the first transfer chamber 34, the third pipeline 21 is connected to the second transfer chamber 35. The top end of the second pipeline 4 extends into the inside of the transfer housing 31. The lower end of the conical rubber ring 33 is sleeved on the upper end of the second pipeline 4. The output component 7 is connected to the liquid storage cavity 101. A first connecting hose 6 is fixedly connected between the third pipeline 21 and the mask component 5. One end of the first connecting hose 6 is detachably sleeved outside the first socket 54. The end of the first connecting hose 6 far from the first socket 54 is fixedly connected to the end of the third pipeline 21 close to the transfer housing 31. A second connecting hose 61 is fixedly connected between the mask component 5 and the output component 7.

[0041] When the first balloon 11 and the second balloon 12 are pressed, the gas inside the oxygen supply chamber 102 will be transported through the first pipe 2 into the inside of the first transfer chamber 34. At this time, the first duckbill soft piece 32 is pushed open by the gas. Then, as the second balloon 12 is continuously pressed, the gas will pass through the transfer member 3 and be supplied to the mask member 5 via the second pipe 4, and then be pressed and delivered into the patient's body. When the first balloon 11 is pressed, a positive pressure will also be generated inside the third pipe 21. Since the third pipe 21 is connected to the second transfer chamber 35, it means that a positive pressure is generated inside the second transfer chamber 35. At this time, the conical rubber ring 33 can be closely attached to the upper end of the second pipe 4 under the action of its own elastic force and the positive pressure of the second transfer chamber 35, so that the second transfer chamber 35 forms a closed chamber, and the gas inside the third pipe 21 cannot enter the inside of the transfer housing 31, ensuring the one-way delivery of oxygen inside the first pipe 2.

[0042] When the first balloon 11 and the second balloon 12 are released, a negative pressure will be generated inside the oxygen supply chamber 102 and the first pipe 2. Then, the first duckbill soft piece 32 will close due to its own elastic rebound and the negative pressure, so that the gas and liquid inside the first transfer chamber 34 cannot enter the inside of the first pipe 2. Along with the elastic rebound of the first balloon 11, a negative pressure will be generated inside the liquid storage chamber 101 and the third pipe 21, which will cause a negative pressure to be generated inside the second transfer chamber 35. At this time, the conical rubber ring 33 will deform under the action of the negative pressure, so that the conical rubber ring 33 opens. At this time, the third pipe 21 will suck gas from the inside of the second pipe 4, and at the same time, it can suck the sputum coughed up by the patient into the inside of the liquid storage chamber 101 through the third pipe 21. The inner diameter of the first connecting hose 6 is much smaller than the inner diameter of the third pipe 21, and the inner diameters of the first connecting hose 6 and the second connecting hose 61 are the same, so that it requires greater resistance for the liquid and gas to pass through.

[0043] A ventilation plate 15 is fixedly installed at the middle position inside the second connecting housing 14. A plurality of uniformly distributed ventilation holes 151 are opened on the ventilation plate 15. A sealing plate 16 is provided on one side of the second connecting housing 14 close to the second balloon 12. A plurality of uniformly distributed stabilizing rods 161 are fixedly installed on the side of the sealing plate 16 close to the ventilation plate 15. The stabilizing rods 161 are slidably clamped on the ventilation plate 15. A plurality of uniformly distributed return springs 17 are fixedly connected between the ventilation plate 15 and the sealing plate 16. The ventilation plate 15 divides the inside of the second connecting housing 14 into a first chamber 141 and a second chamber 142. A first connecting pipe 18 and a second connecting pipe 19 are fixedly installed on one side of the second connecting housing 14 away from the second balloon 12. A threaded cylinder 181 is fixedly installed on the first connecting pipe 18. A plug connector 191 is fixedly installed on the second connecting pipe 19. The oxygen storage bag 8 is sleeved outside the threaded cylinder 181 by thread fitting. The oxygen delivery pipe 9 is sleeved outside the plug connector 191.

[0044] Before use, connect the oxygen delivery tube 9 to the output end of the external oxygen supply device, then fix the oxygen storage bag 8 to the threaded cylinder 181, and then press the balloon component 1. At this time, positive pressure is generated inside the oxygen supply chamber 102. At this time, the sealing plate 16 will enter the inside of the second connection housing 14 under the action of the return spring 17 and the positive pressure. At this time, the oxygen delivery tube 9 inputs oxygen into the inside of the first chamber 141 through the second connecting tube 19, and the oxygen is blocked by the sealing plate 16. At this time, the oxygen will enter the inside of the oxygen storage bag 8 through the first connecting tube 18 for storage. When the second balloon 12 is released, at this time, because negative pressure is generated inside the oxygen supply chamber 102, a pulling effect will be exerted on the sealing plate 16. At this time, the sealing plate 16 will be disengaged from the inside of the second connection housing 14. Due to the negative pressure effect of the oxygen supply chamber 102, the oxygen inside the oxygen delivery tube 9 and the oxygen storage bag 8 will be sucked into the inside of the oxygen supply chamber 102. Furthermore, when the device inputs air to the patient, the oxygen delivery tube 9 can automatically inflate the oxygen storage bag 8, store oxygen when blowing air to the patient, and then the device automatically inhales air, making the oxygen input more stable. The oxygen storage bag 8 can also provide additional oxygen supply when the oxygen supply of the oxygen delivery tube 9 is unstable, making the device safer and more stable during use.

[0045] The mask component 5 includes a sealing cover body 51. A surrounding pipe 52 is fixedly installed at the bottom end of the sealing cover body 51. A plurality of uniformly distributed liquid leakage grooves 53 are formed at the upper position of the inner circle of the surrounding pipe 52. A first socket 54 is fixedly installed at the lower end of the outer side of the surrounding pipe 52. A second socket 55 is fixedly installed at the lower end of the outer side of the surrounding pipe 52 away from the first socket 54. Both the first socket 54 and the second socket 55 are communicated with the inside of the surrounding pipe 52.

[0046] Because the mask component 5 is pressed against the patient's mouth, during use, if the patient has epilepsy or other conditions such as drowning, when performing assisted breathing, it is easy to cause the patient to flow out more saliva or other liquids to be covered by the mask component 5 and stay around the patient's lips. Not only is it easy to be blown into the patient's body during assisted breathing, causing the patient to choke again, but it will also cause the patient's lips to be corroded and inflamed.

[0047] Therefore, by setting the surrounding pipe 52, when the patient spits out liquid, the liquid will enter the inside of the surrounding pipe 52 through the liquid leakage groove 53. When the balloon component 1 is pressed, the second pipe 4 will input gas into the inside of the sealing cover 51, so that a positive pressure is generated inside the sealing cover 51. At this time, because a positive pressure is also generated inside the third pipe 21, the positive pressure will be conveyed to the inside of the surrounding pipe 52 through the first connecting hose 6 and the first socket 54. Along with the positive pressure generated inside the sealing cover 51, the liquid inside the surrounding pipe 52 will be squeezed and enter the inside of the output component 7 through the second connecting hose 61 and be discharged out of the device by the output component 7. When the first balloon 11 and the second balloon 12 elastically rebound after the hand is released, at this time, due to the exhalation of the patient, the air pressure inside the sealing cover 51 hardly changes. Because the other end of the first connecting hose 6 is connected to the third pipe 21, the liquid inside the surrounding pipe 52 will be sucked into the inside of the third pipe 21 by the first connecting hose 6. Therefore, by setting the first connecting hose 6 and the second connecting hose 61, whether the balloon component 1 is pressed or released, it can suck and drain the liquid around the patient's lips, preventing the liquid spit out by the patient from staying around the lips for a long time and causing secondary choking of the patient, as well as the situation of corrosion to the lips, and further improving the safety when the device is used.

[0048] The output component 7 includes an output pipe 71. A first connecting joint 72 is fixedly installed at the top end of the output pipe 71. Two symmetric second duckbill soft pieces 73 are arranged inside the first connecting joint 72. A second connecting joint 74 is fixedly installed at the bottom end of the output pipe 71. The second duckbill soft piece 73 is used to control that the liquid and gas inside the liquid storage cavity 101 can only enter the inside of the first connecting joint 72 unidirectionally. One end of the second connecting hose 61 is detachably sleeved outside the second socket 55, and the end of the second connecting hose 61 away from the second socket 55 is fixedly connected to the output pipe 71.

[0049] By setting the output component 7, when the balloon component 1 is continuously pressed, the waste liquid inside the liquid storage cavity 101 can be continuously discharged, realizing the cyclic output of the liquid. Even for a drowning patient who will discharge a large amount of liquid, there is no need to repeatedly stop working and then clean up, and the cyclic cleaning can be realized along with the progress of the auxiliary work.

[0050] The inside of the first connecting pipe 18 and the second connecting pipe 19 has a ventilation groove 182. A spherical valve core 183 is connected and arranged in the middle of the ventilation groove 182 through a ball socket connection. A central groove 185 is opened in the middle of the spherical valve core 183. Rotating handles 184 are rotatably installed on both the first connecting pipe 18 and the second connecting pipe 19, and the rotating handles 184 are fixedly installed on the corresponding spherical valve cores 183.

[0051] When in use, by rotating the corresponding handle 184, the overlapping amount of the central groove 185 and the ventilation groove 182 can be adjusted, thereby controlling the resistance of gas passage, changing the gas passage resistance of the first connecting pipe 18 and the second connecting pipe 19, and then when the oxygen supply chamber 102 sucks, changing the gas volume supplied by the oxygen storage bag 8 and the oxygen delivery pipe 9, so that the oxygen delivery pipe 9 can be connected to the plug connector 191 during use, and the oxygen storage bag 8 does not need to be installed on the threaded cylinder 181. At this time, when the oxygen supply chamber 102 generates negative pressure, the amount of outdoor air sucked from the first connecting pipe 18 and the amount of oxygen sucked from the second connecting pipe 19 can be changed due to different resistances, or the oxygen storage bag 8 can be filled with oxygen, and then the oxygen storage bag 8 is connected to the threaded cylinder 181, and the oxygen delivery pipe 9 is removed from the plug connector 191, so that the oxygen content of the gas supplied by the device can be quickly changed, thereby improving the ability of assisted respiration and making the device more efficient.

[0052] Through reasonable layout, after the use of this device, only need to block the mask component 5, then remove the oxygen delivery pipe 9 from the plug connector 191, and then connect the plug connector 191 to an external water supply device. The water supply device inputs water flow into the interior of the plug connector 191. The water flow will pass through the second connecting housing 14, push open the sealing plate 16 and enter the interior of the oxygen supply chamber 102, and then enter the interior of the first transfer chamber 34 through the first pipe 2. Because the mask component 5 is blocked, the water flow will push open the conical rubber ring 33 and then enter the interior of the second transfer chamber 35 and the third pipe 21. Then the water flow will pass through the third pipe 21 and enter the interior of the liquid storage chamber 101, and finally be discharged from the device through the output component 7, so that the device can quickly clean all components of the entire device after use, with quick and thorough cleaning.

[0053] By setting the second pipe 4 in this device, when the oxygen supply chamber 102 blows air into the patient's body, if it exceeds the tolerance of the patient's lungs, at this time, the pressure generated by the first pipe 2 increases, which will then push open the conical rubber ring 33, so that the excess air will pass through the conical rubber ring 33 and be discharged from the device through the third pipe 21. When the liquid storage chamber 101 sucks air, if it sucks excessively, at this time, the negative pressure at the second transfer chamber 35 increases, and the negative pressure at the second transfer chamber 35 will exceed the negative pressure generated inside the first pipe 2. Then the third pipe 21 will suck air from the inside of the first pipe 2, making the device have higher safety during use, preventing damage to the patient's lungs caused by excessive blowing or excessive inhalation, and preventing the occurrence of lung complications.

[0054] Working principle: When the balloon component 1 is pressed, positive pressure is generated inside both the liquid storage cavity 101 and the oxygen supply cavity 102. At this time, the gas and liquid inside the liquid storage cavity 101 will be discharged through the output component 7, while the gas inside the oxygen supply cavity 102 will be output to the transfer part 3 through the first pipeline 2. The transfer part 3 will then transport the gas to the mask component 5 through the second pipeline 4. The mask component 5 is pressed against the patient's mouth, thereby realizing pumping gas into the patient's body. At the same time, the waste liquid and waste gas inside the liquid storage cavity 101 are discharged through the output component 7. When the hand is released, at this time, the first balloon 11 and the second balloon 12 undergo elastic rebound, generating negative pressure in the liquid storage cavity 101 and the oxygen supply cavity 102. The liquid storage cavity 101 sucks air from inside the transfer part 3 through the third pipeline 21. At this time, the transfer part 3, the second pipeline 4, and the mask component 5 are connected, causing the gas exhaled by the patient to enter the inside of the liquid storage cavity 101 along the third pipeline 21. If the patient coughs or spits out phlegm during exhalation, it will enter the inside of the third pipeline 21 along with the negative pressure and finally be sucked into the inside of the liquid storage cavity 101. When the second balloon 12 undergoes elastic rebound and returns to its original state, the oxygen supply cavity 102 sucks oxygen from the oxygen delivery tube 9 and the oxygen storage bag 8. When the second balloon 12 is pressed, the oxygen supply from the oxygen storage bag 8 and the oxygen delivery tube 9 stops;

[0055] When the oxygen supply cavity 102 blows air into the patient's body, if it exceeds the tolerance of the patient's lungs, at this time, the pressure generated by the first pipeline 2 increases, which will then push the conical rubber ring 33 to open, allowing the excess air to pass through the conical rubber ring 33 and be discharged from the device through the third pipeline 21. When the liquid storage cavity 101 sucks air, if it sucks excessively, at this time, the negative pressure at the second transfer chamber 35 increases. At this time, the negative pressure at the second transfer chamber 35 will exceed the negative pressure generated inside the first pipeline 2, and then the third pipeline 21 will suck air from inside the first pipeline 2 to prevent excessive blowing or excessive inhalation.

[0056] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
