Description

Technical Field

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

[0002] Critical care patients 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 assistive devices have been widely used in clinical practice to help patients maintain their lives. Existing respiratory rehabilitation assistive devices mainly include mechanical ventilators, high-flow nasal positive pressure ventilation (HFNC) and continuous positive airway pressure (CPAP). These devices have their own advantages and disadvantages. For example, mechanical ventilators have strong adjustment functions, but they are more uncomfortable when used. HFNC and CPAP are more comfortable, but their ability to control the patient's lung osmotic pressure is limited. In response to these problems, in recent years, many researchers have been committed to developing safer, more effective and comfortable respiratory rehabilitation assistive devices; some researchers have explored new ideas such as sonic airflow assisted breathing, lung function training equipment, and the use of artificial intelligence technology to dynamically adjust ventilation parameters; at the same time, some researchers have focused on incorporating comfort into device design, such as reducing respiratory resistance and improving the wearing experience; However, existing respiratory rehabilitation assist devices still have shortcomings in specific critical care patient groups; for example, for some patients with special diseases such as epilepsy or special physiological characteristics, existing devices cannot quickly clean up the saliva and sputum spit out by the patients when in use. In order to prevent the patients from choking on the liquid, it is necessary to stop working, clean up the liquid and then perform assisted breathing again; therefore, developing a respiratory rehabilitation assist device for critical care patient groups to improve treatment effects and reduce patients' adverse reactions is still an important topic.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0024] See also Figures 1 to 8 A respiratory rehabilitation assist device for critical care patients comprises 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 on the upper end of the side of the balloon component 1 close to the first pipe 2, a transfer component 3 for controlling the gas flow direction is fixedly installed on the end of the first pipe 2 away from the balloon component 1, an end of the first pipe 2 away from the balloon component 1 is fixedly installed on the side surface of the transfer component 3, a second pipe 4 is fixedly installed on the lower end of the transfer component 3, a mask component 5 is fixedly installed on the end of the second pipe 4 away from the transfer component 3, an oxygen storage bag 8 and an oxygen supply tube 9 are installed on the side of the balloon component 1 away from the first pipe 2, the balloon component 1 comprises a first balloon 11, an output component 7 for drainage is fixedly installed on the lower end of the first balloon 11, and a second balloon 12 is provided at the inner center of the first balloon 11.

[0025] During actual use, by squeezing the balloon component 1, oxygen can be pumped into the patient's body to assist the patient's breathing. After the pressure on the balloon component 1 is lost, the balloon component 1 can elastically rebound to return to its original state. When the balloon component 1 returns to its original state, negative pressure can be generated to assist the patient's exhalation, and at the same time, sputum or other liquids blocked in the patient's body can be sucked out. In emergency, some patients may have weak breathing or even inability to breathe independently due to choking or other foreign objects blocking the pipes, so they need to receive respiratory rehabilitation assistance. However, during use, it is easy to cause sputum blocking the patient's body. When saliva, water or other liquids are used to assist breathing, they need to be constantly cleaned. When facing some critically ill patients, they need to be immediately assisted in breathing rehabilitation and cannot be intubated, which causes the liquid and sputum in the patient's body to contaminate and block the auxiliary device. The device is provided with a first balloon 11 and a second balloon 12, so that it can absorb the liquid sprayed by the patient while assisting breathing and store it in different chambers. It can not only prevent sputum and other liquids from contaminating the device, but also guide the liquid to be discharged without stopping assisted breathing, which has a better auxiliary effect on the patient and is more suitable for emergency patients.

[0026] The second balloon 12 has a first connecting shell 13 and a second connecting shell 14 integrally formed at both ends thereof. The first pipe 2 is fixedly mounted on the first connecting shell 13. A liquid storage chamber 101 is formed between the interior of the first balloon 11 and the second balloon 12. The interior of the second balloon 12 has an oxygen supply chamber 102. The third pipe 21 is connected to the liquid storage chamber 101, and the first pipe 2 is connected to the oxygen supply chamber 102.

[0027] When the balloon component 1 is pressed, positive pressure is generated inside the liquid storage chamber 101 and the oxygen supply chamber 102. At this time, the gas and liquid inside the liquid storage chamber 101 will be discharged through the output component 7, and the gas inside the oxygen supply chamber 102 will be output to the transfer component 3 through the first pipe 2. The transfer component 3 will then transport the gas to the mask component 5 through the second pipe 4. The mask component 5 is pressed on the patient's mouth, thereby pumping the gas into the patient's body, and at the same time, the waste liquid and waste gas inside the liquid storage chamber 101 are discharged through the output component 7. When the hand is released, the first balloon 11 and the second balloon 12 will rebound elastically, and the liquid storage chamber 101 and the oxygen supply chamber 102 will generate negative pressure. The liquid cavity 101 draws air from the inside of the transfer component 3 through the third pipe 21. At this time, the transfer component 3, the second pipe 4, and the mask component 5 are connected, so that the patient's exhaled air will enter the liquid storage cavity 101 along the third pipe 21. If the patient coughs or spit out sputum while exhaling, the air will enter the inside of the third pipe 21 with the negative pressure and finally be sucked into the liquid storage cavity 101. When the second balloon 12 rebounds elastically to restore its original state, the oxygen supply cavity 102 will absorb oxygen from the oxygen supply tube 9 and the oxygen storage bag 8. When the second balloon 12 is pressed, the oxygen storage bag 8 and the oxygen supply tube 9 stop supplying oxygen, which can prevent excessive oxygen supply.

[0028] The transfer member 3 includes a transfer shell 31, and two mutually symmetrical first duckbill soft sheets 32 are fixedly installed on the upper end of the interior of the transfer shell 31. The first duckbill soft sheet 32 ​​is used to allow the gas inside the first pipe 2 to enter the first transfer chamber 34 in one direction only. A conical rubber ring 33 is fixedly installed in the middle of the transfer shell 31. The conical rubber ring 33 divides the interior of the transfer shell 31 into a first transfer chamber 34 and a second transfer chamber 35. The first pipe 2 is connected to the first transfer chamber 34, the third pipe 21 is connected to the second transfer chamber 35, and the second pipe 21 is connected to the second transfer chamber 35. The top of the channel 4 extends into the interior of the transfer shell 31, the lower end of the conical rubber ring 33 is sleeved on the upper end of the second pipe 4, the output component 7 is connected to the liquid storage chamber 101, and a first connecting hose 6 is fixedly connected between the third pipe 21 and the mask component 5, one end of the first connecting hose 6 is detachably sleeved on the outside of the first plug interface 54, and one end of the first connecting hose 6 away from the first plug interface 54 is fixedly connected to one end of the third pipe 21 close to the transfer shell 31, and a second connecting hose 61 is fixedly connected between the mask component 5 and the output component 7.

[0029] When the first balloon 11 and the second balloon 12 are pressed, the gas inside the oxygen supply chamber 102 will be transported to the inside of the first transfer chamber 34 through the first pipe 2. At this time, the first duckbill soft film 32 is pushed open by the gas, and then as the second balloon 12 is continuously pressed, the gas will pass through the transfer part 3 and the second pipe 4 to the mask part 5, and then be pressed and transported into the patient's body. When the first balloon 11 is pressed, a positive pressure will also be generated inside the third pipe 21, because the third pipe 21 is connected to the second transfer chamber 35, which means that a positive pressure is generated inside the second transfer chamber 35. At this time, the conical rubber ring 33 can fit tightly with 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 interior of the transfer shell 31, thereby ensuring the one-way delivery of oxygen inside the first pipe 2.

[0030] When the first balloon 11 and the second balloon 12 are released, negative pressure will be generated inside the oxygen supply chamber 102 and the first pipe 2, and the first duckbill soft film 32 will be closed due to its own elastic rebound and negative pressure, so that the gas and liquid inside the first transfer chamber 34 cannot enter the first pipe 2. As the first balloon 11 rebounds elastically, negative pressure will be generated inside the liquid storage chamber 101 and the third pipe 21, which will cause negative pressure to be generated inside the second transfer chamber 35. At this time, the conical rubber ring 33 will be deformed under the action of negative pressure, so that the conical rubber ring 33 will open. At this time, the third pipe 21 will absorb gas from the inside of the second pipe 4, and at the same time, the sputum coughed up by the patient can be absorbed into 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 liquid and gas need greater resistance to pass through.

[0031] A breathable plate 15 is fixedly installed in the middle position of the interior of the second connecting shell 14, and a plurality of evenly distributed breathable holes 151 are opened on the breathable plate 15. A sealing plate 16 is provided on the side of the interior of the second connecting shell 14 close to the second balloon 12. A plurality of evenly distributed stabilizing rods 161 are fixedly installed on the side of the sealing plate 16 close to the breathable plate 15. The stabilizing rods 161 are slidably clamped on the breathable plate 15, and a plurality of evenly distributed return springs 17 are fixedly connected between the breathable plate 15 and the sealing plate 16. The breathable plate 15 divides the interior of the second connecting shell 14 into a first chamber 141 and a second chamber 142. A first connecting tube 18 and a second connecting tube 19 are fixedly installed on the side of the second connecting shell 14 away from the second balloon 12. A threaded barrel 181 is fixedly installed on the first connecting tube 18, and a plug connector 191 is fixedly installed on the second connecting tube 19. The oxygen storage bag 8 is sleeved on the outside of the threaded barrel 181 through threaded cooperation, and the oxygen supply tube 9 is sleeved on the outside of the plug connector 191.

[0032] Before use, connect the oxygen supply tube 9 to the output end of the external oxygen supply device, then fix the oxygen storage bag 8 to the threaded tube 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 second connecting shell 14 under the action of the return spring 17 and the positive pressure. At this time, the oxygen supply tube 9 inputs oxygen into 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 oxygen storage bag 8 through the first connecting tube 18 for storage. When the second balloon 12 is released, negative pressure is generated inside the oxygen supply chamber 102. , so it will have a pulling effect on the sealing plate 16, and at this time the sealing plate 16 will be detached from the inside of the second connecting shell 14. Due to the negative pressure of the oxygen supply chamber 102, the oxygen inside the oxygen supply tube 9 and the oxygen storage bag 8 will be sucked into the inside of the oxygen supply chamber 102, so that when the device inputs air to the patient, the oxygen supply tube 9 can automatically inflate the oxygen storage bag 8, and can store oxygen when blowing air to the patient. Then the device can autonomously inhale air, making the oxygen input more stable. The oxygen storage bag 8 can also provide additional oxygen supply when the oxygen supply in the oxygen supply tube 9 is unstable, making the device safer and more stable when used.

[0033] 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 evenly distributed leakage grooves 53 are opened above the inner circle of the surrounding pipe 52, a first plug interface 54 is fixedly installed at the lower end of one side of the outside of the surrounding pipe 52, and a second plug interface 55 is fixedly installed at the lower end of the side of the outside of the surrounding pipe 52 away from the first plug interface 54. Both the first plug interface 54 and the second plug interface 55 are connected to the interior of the surrounding pipe 52.

[0034] Because the mask component 5 is pressed against the patient's mouth, when in use, if the patient has epilepsy or other conditions such as drowning, when assisted breathing is performed, it is easy for the patient to secrete a lot of saliva or other liquids, which will be covered by the mask component 5 and remain around the patient's lips. Not only can it be easily blown into the patient's body during assisted breathing, causing the patient to choke for the second time, it can also cause corrosion and inflammation around the patient's lips.

[0035] Therefore, the device is provided with a surrounding pipe 52. When the patient spits out liquid, the liquid will enter the interior of the surrounding pipe 52 through the leakage groove 53. When the balloon component 1 is pressed, the second pipe 4 will input gas into the interior of the sealing cover 51, thereby generating a positive pressure 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 transmitted to the interior of the surrounding pipe 52 through the first connecting hose 6 and the first plug interface 54. Along with the positive pressure generated inside the sealing cover 51, the liquid inside the surrounding pipe 52 will be squeezed through the second connecting hose 61 into the interior of the output component 7 and discharged out of the device by the output component 7. When the first ball is released, When the balloon 11 and the second balloon 12 rebound elastically, the air pressure inside the sealing cover 51 hardly changes due to the patient's exhalation. Since 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 third pipe 21 by the first connecting hose 6. Therefore, the device is provided with the first connecting hose 6 and the second connecting hose 61. Whether the balloon component 1 is pressed or released, the patient's lips can be sucked and discharged, thereby preventing the patient's spitted liquid from staying around the lips for a long time to cause secondary choking of the patient and corrosion of the lips, thereby further improving the safety of the device when in use.

[0036] The output component 7 includes an output tube 71, a first connecting section 72 is fixedly installed on the top of the output tube 71, two second duckbill soft films 73 are symmetrically arranged inside the first connecting section 72, a second connecting section 74 is fixedly installed on the bottom of the output tube 71, the second duckbill soft film 73 is used to control the liquid and gas inside the liquid storage chamber 101 to only enter the first connecting section 72 in one direction, one end of the second connecting hose 61 is detachably mounted on the outside of the second plug interface 55, and the end of the second connecting hose 61 away from the second plug interface 55 is fixedly connected to the output tube 71.

[0037] By providing an output component 7, the device can continuously discharge the waste liquid inside the liquid storage chamber 101 when the balloon component 1 is continuously pressed, thereby realizing the circulating output of the liquid. Even in the case of drowning patients who will discharge a large amount of liquid, there is no need to repeatedly stop working and then clean up, and circulating cleaning can be achieved as the auxiliary work is carried out.

[0038] The first connecting tube 18 and the second connecting tube 19 have ventilation grooves 182 inside, and a ball valve core 183 is provided in the middle of the ventilation groove 182 through a ball and socket connection card, and a central groove body 185 is opened in the middle of the ball valve core 183. The first connecting tube 18 and the second connecting tube 19 are both rotatably installed with a turning handle 184, and the turning handle 184 is fixedly installed on the corresponding ball valve core 183.

[0039] When in use, the overlap between the central slot 185 and the ventilation slot 182 can be adjusted by turning the corresponding turning handle 184, thereby controlling the resistance to gas passage, changing the resistance to gas passage of the first connecting tube 18 and the second connecting tube 19, and then changing the amount of gas delivered by the oxygen storage bag 8 and the oxygen delivery tube 9 when the oxygen supply chamber 102 absorbs. This allows the oxygen delivery tube 9 to be connected to the plug connector 191 when in use, and there is no need to install the oxygen storage bag 8 on the threaded tube 181. At this time, when the oxygen supply chamber 102 generates negative pressure, the amount of outdoor air absorbed from the first connecting tube 18 and the amount of oxygen absorbed from the second connecting tube 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 tube 181, and the oxygen delivery tube 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 breathing and making the device more efficient.

[0040] Through reasonable layout, after use, the present device only needs to block the mask component 5, then remove the oxygen supply tube 9 from the plug connector 191, and then connect the plug connector 191 to the external water supply device. The water supply device inputs water flow into the plug connector 191, and the water flow passes through the second connecting shell 14 to push open the sealing plate 16 and enter the interior of the oxygen supply chamber 102, and then passes through the first pipe 2 to enter the interior of the first transfer chamber 34. Because the mask component 5 is blocked, the water flow pushes the conical rubber ring 33 to open and then enters the interior of the second transfer chamber 35 and the third pipe 21, and then the water flow passes through the third pipe 21 to enter the interior of the liquid storage chamber 101, and finally discharges the device through the output component 7, so that the device can quickly clean all components of the entire device after use, and the cleaning is fast and thorough.

[0041] The device is provided with a second pipe 4. When the oxygen supply chamber 102 blows air into the patient's body, if it exceeds the tolerance of the patient's lungs, the pressure generated by the first pipe 2 increases, which will push the conical rubber ring 33 to open, so that the excess air will pass through the conical rubber ring 33 and then be discharged from the device through the third pipe 21. When the liquid storage chamber 101 absorbs air, if it is excessively absorbed, 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 pipe 2, and then the third pipe 21 will absorb air from the inside of the first pipe 2, so that the device has higher safety when used, and prevents damage to the patient's lungs caused by excessive blowing or excessive inhalation, and prevents the occurrence of lung complications.

[0042] Working principle: When the balloon component 1 is pressed, positive pressure is generated inside the liquid storage chamber 101 and the oxygen supply chamber 102. At this time, the gas and liquid inside the liquid storage chamber 101 will be discharged through the output component 7, and the gas inside the oxygen supply chamber 102 will be output to the transfer component 3 through the first pipe 2. The transfer component 3 will then deliver the gas to the mask component 5 through the second pipe 4. The mask component 5 is pressed on the patient's mouth to pump the gas into the patient's body, and at the same time, the waste liquid and waste gas inside the liquid storage chamber 101 are discharged through the output component 7. When the hand is released, the first balloon 11 and the second balloon 12 will rebound elastically, and the liquid storage chamber 101 and the oxygen supply chamber 102 will be discharged through the output component 7. 2 generates negative pressure, and the liquid storage chamber 101 absorbs air from the inside of the transfer part 3 through the third pipe 21. At this time, the transfer part 3, the second pipe 4, and the mask component 5 are connected, which will allow the patient's exhaled air to enter the liquid storage chamber 101 along the third pipe 21. If the patient coughs or spit out sputum during exhalation, it will enter the inside of the third pipe 21 with the negative pressure and finally be absorbed into the liquid storage chamber 101. When the second balloon 12 rebounds and returns to its original state, the oxygen supply chamber 102 will absorb oxygen from the oxygen supply tube 9 and the oxygen storage bag 8. When the second balloon 12 is pressed, the oxygen storage bag 8 and the oxygen supply tube 9 stop supplying oxygen. When the oxygen supply chamber 102 blows air into the patient's body, if it exceeds the tolerance of the patient's lungs, the pressure generated by the first pipe 2 increases, which will push the conical rubber ring 33 to open, so that the excess air will pass through the conical rubber ring 33 and be discharged from the device by the third pipe 21. When the liquid storage chamber 101 absorbs air, if it is excessively absorbed, 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 pipe 2, and then the third pipe 21 will absorb air from the inside of the first pipe 2 to prevent excessive blowing or excessive inhalation.
