The Department of Critical Care Medicine's primary focus includes emergency rescue and ongoing life support for critically ill patients, treatment and organ function support for patients with multiple organ dysfunction, and prevention and treatment of multiple organ dysfunction syndrome (MODS). In critical care medicine, some patients with compromised airways require external assistance to restore breathing, as well as breathing training to help them regain respiratory function.

[0022] The lifting assembly includes an L-support plate 3, which is fixed between the fixed frame 2 and the movable base 1. A first screw rod 4 is arranged between the top of the L-support plate 3 and the fixed frame 2. A movable block 5 is threaded on the first screw rod 4.

The threaded cooperation between the movable block 5 and the first screw rod 4 facilitates the adjustment of the movable block 5 to move up and down. Combined with the movable rod 6, the mounting plate 7 is driven to move up and down synchronously, thereby achieving the purpose of adjusting the height of the air inlet pipe 17 and the air outlet pipe 18 to adapt to different usage scenarios.

[0023] The reciprocating circulation component includes a first hydraulic cylinder 21 and a second hydraulic cylinder 25. The first hydraulic cylinder 21 and the second hydraulic cylinder 25 are relatively arranged at the top inner side of the U-shaped frame 8, and the bottoms of the first hydraulic cylinder 21 and the second hydraulic cylinder 25 are both connected to the liquid storage cylinder 9. An air inlet hole is opened through the bottom of the inner cavity of the air intake cylinder 17, and the air intake cylinder 17 and the first temporary air storage cylinder 15 are connected through the air intake hole. A first disc 22 is movably provided in the inner cavity of the first hydraulic cylinder 21, and a first rod body 24 is fixed on the top of the first disc 22. A first sealing plate 23 is movably provided in the inner cavity of the air intake cylinder 17, and the first sealing plate 23 cooperates with the air inlet hole. The upper end of the first rod body 24 passes through the first hydraulic cylinder 21, the first temporary air storage cylinder 15 and the air inlet hole and is fixedly connected to the first sealing plate 23. The first rod body 24 movably cooperates with the first hydraulic cylinder 21 and the first temporary air storage cylinder 15.

[0024] A second disc 26 is movably provided in the inner cavity of the second hydraulic cylinder 25, and a second rod body 28 is fixedly connected to the top of the second disc 26. A second sealing plate 27 is movably provided in the inner cavity of the air outlet cylinder 18. An air outlet hole is opened through the bottom of the inner cavity of the air outlet cylinder 18. The air outlet cylinder 18 is connected to the second temporary air storage cylinder 16 through the air outlet hole. The second sealing plate 27 cooperates with the air outlet hole. The upper end of the second rod body 28 passes through the second hydraulic cylinder 25, the second temporary air storage cylinder 16 and the air outlet hole and is fixedly connected to the second sealing plate 27.

[0025] A plurality of universal wheels 29 are installed at the bottom of the mobile base 1, and a support plate 30 is fixed to the outer wall of the fixed frame 2. A screw 31 is threaded on the support plate 30, and a rubber plate 32 is connected to the upper end of the screw 31. A knob is fixed to the lower end of the screw 31.

[0026] A motor 33 is installed on one side of the fixed plate 13, and the output end of the motor 33 is connected to one end of the reciprocating screw 14. A guide rod 34 is fixed on the inner side of the U-shaped frame 8. The guide rod 34 passes through the movable plate 12, and the movable plate 12 slides with the guide rod 34. The guide rod 34 effectively limits and guides the movable plate 12, thereby ensuring the stability of the reciprocating movement of the movable plate 12, and further ensuring the stability of the reciprocating movement of the piston plate 11 driven by the piston rod 10.

[0027] Several electric heating tubes 35 are installed around the inner wall of the air inlet cylinder 17 to heat the gas inhaled by the patient. Several ultraviolet lamps 36 are installed on the top of the inner cavity of the air outlet cylinder 18 to sterilize and disinfect the gas exhaled by the patient and prevent the gas exhaled by the patient from entering the interior of the device and causing bacteria to grow. The top of the air inlet cylinder 17 is connected to an air inlet pipe, and the outer wall of the air outlet cylinder 18 is connected to an air outlet pipe. A one-way valve is installed on the side of the air supply pipe 19 close to the mask 20. The two one-way valves correspond to the air inlet cylinder 17 and the air outlet cylinder 18 respectively. The one-way valve facilitates the intake and exhaust of the inside of the mask 20, adapts to the patient's exhalation and inhalation, and is convenient for use.

[0028] A servo motor 37 is installed on the inner side of the L-support plate 3, and the output end of the servo motor 37 is connected to the lower end of the first screw rod 4. A hook 38 is fixed to the outer wall of the fixing frame 2, and an elastic rope is provided on the mask 20. The elastic rope and the hook 38 cooperate with each other, so that the mask 20 can be hung on one side of the fixing frame 2 when it is stored after use. Two limit frames 39 are relatively fixed on the top of the mobile base 1, and one side of the limit frame 39 is fixedly connected to the fixing frame 2, which facilitates the placement of the oxygen cylinder.

[0029] Example: When in use, first fix the oxygen cylinder on the limiting frame 39, and connect the outlet port of the oxygen cylinder to the air inlet pipe at the upper end of the air inlet cylinder 17. At the same time, under the action of the universal wheel 29, move the entire device to the side of the bed, and turn the knob. Under the thread cooperation of the screw rod 31 and the support plate 30, the adjustment screw rod 31 rotates upward, thereby driving the rubber plate 32 to move upward synchronously until the rubber plate 32 abuts against the bottom of the bed board, thereby achieving the purpose of fixing the device. Secondly, the servo motor 37 is started, and the first screw rod 4 is driven to rotate by the servo motor 37. Under the threaded cooperation between the movable block 5 and the first screw rod 4, the movable block 5 is adjusted to move up and down. Combined with the movable cooperation between the movable rod 6 and the fixed frame 2, the mounting plate 7 is driven to move up and down synchronously, thereby achieving the purpose of adjusting the height of the air inlet cylinder 17, the air outlet cylinder 18, the first temporary air reservoir 15 and the second temporary air reservoir 16 to adapt to different usage scenarios; Then, the mask 20 is fixed to the patient's mouth and nose by an elastic rope. Under the action of the one-way valve, the oxygen in the first temporary air reservoir 15 is delivered to the mask 20 through the air supply pipe 19 thereon, and the exhaled gas of the patient is delivered to the second temporary air reservoir 16 through the air supply pipe 19 on the second temporary air reservoir 16, thereby achieving the purpose of oxygen supply to the patient. At this time, the motor 33 is started, and the reciprocating screw 14 is driven to rotate by the motor 33. Under the threaded cooperation between the movable plate 12 and the reciprocating screw 14, combined with the sliding cooperation between the movable plate 12 and the guide rod 34, the movable plate 12 is driven to move back and forth stably. As the movable plate 12 moves, under the active cooperation between the piston rod 10 and the liquid storage cylinder 9, the piston plate 11 is driven to reciprocate synchronously in the inner cavity of the liquid storage cylinder 9. When the piston plate 11 moves toward the direction approaching the first hydraulic cylinder 21, the hydraulic oil on one side of the inner cavity of the liquid storage cylinder 9 is squeezed into the first hydraulic cylinder 21. As the hydraulic oil entering the first hydraulic cylinder 21 increases, the first disc 22 is pushed upward. Under the action of the first rod 24, the first sealing plate 23 is driven to move upward synchronously and away from the air inlet hole. The air inlet cylinder 17 is connected to the first temporary air reservoir 15. The oxygen inside the air inlet cylinder 17 enters the first temporary air reservoir 15 through the air inlet hole, and is delivered to the mask 20 through the air supply pipe 19 connected to one side of the first temporary air reservoir 15, so as to cooperate with the patient's inhalation movement. During this process, the space in the inner cavity of the liquid storage cylinder 9 near the second hydraulic cylinder 25 increases, making it impossible for the second hydraulic cylinder 25 to be filled with hydraulic oil. Under the action of gravity, the second disc 26 moves downward along the inner cavity of the second hydraulic cylinder 25. Under the action of the second rod 28, it drives the second sealing plate 27 downward to block the air outlet. When the piston plate 11 moves in the direction away from the first hydraulic cylinder 21, the hydraulic oil on the other side of the inner cavity of the liquid storage cylinder 9 is squeezed into the second hydraulic cylinder 25. As the hydraulic oil entering the second hydraulic cylinder 25 increases, the second disc 26 is pushed upward, and combined with the second rod body 28, the second sealing plate 27 is pushed upward and away from the air outlet. The air outlet cylinder 18 is connected to the second temporary air reservoir 16. The gas exhaled by the patient enters the air outlet cylinder 18 through the second temporary air reservoir 16 and the air outlet, cooperating with the patient's exhalation movement. Under the action of the ultraviolet lamp 36, the patient's exhaled gas is sterilized and disinfected to prevent the patient's exhaled gas from remaining in the device and causing bacterial growth; During this process, the space in the inner cavity of the liquid storage cylinder 9 near the first hydraulic cylinder 21 increases, making it impossible for the first hydraulic cylinder 21 to be filled with hydraulic oil. Under the action of gravity, the first disc 22 moves downward along the inner cavity of the first hydraulic cylinder 21. Under the action of the first rod 24, it drives the first sealing plate 23 downward to block the air inlet hole. The reciprocating movement of the movable plate 12 drives the synchronous reciprocating movement of the piston plate 11, realizing the reciprocating cycle of the above-mentioned movement, which can simulate the state of the patient's lung breathing, thereby conducting rehabilitation training for the patient's respiratory system, preventing the lungs from becoming dependent on long-term oxygen supply, and preventing the patient from breathing with droplets. This solves the problem that the existing respiratory assistance recovery device for critical care nursing cannot imitate the breathing rhythm of the human lungs and can only continuously deliver oxygen, which will cause the patient to become dependent, resulting in reduced lung respiratory function and affecting the patient's recovery, and facilitates the patient's recovery. The electric heating tube 35 is used to heat the oxygen inside the air inlet cylinder 17, thereby ensuring the comfort of the patient inhaling oxygen.

[0030] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the motor 33, electric heating tube 35, ultraviolet lamp 36 and servo motor 37 in the present invention are all purchased on the market, and those skilled in the art can install and use them according to requirements.
