[0015] As a preferred embodiment of the post-tracheal ventilator assist device of the present invention, wherein: One side of the return pipe is ring-arranged and passes through the ring cavity, and then passes through the ring sleeve, the insulation sleeve, the insulation cavity and the second open cavity plate on one side of the partition plate in sequence, and then bends and passes through the adapter and the second open cavity plate on the other side of the partition plate to pass through the insulation cavity, and then passes through the insulation sleeve and the ring sleeve on the other side to close contact with the other side of the return pipe to form a closed loop, and the interior of the return pipe is filled with pure water, and the surface of the insulation sleeve is provided with a supporting sleeve.

[0016] As a preferred embodiment of the post-tracheal ventilator assist device of the present invention, wherein: The surface of the respiratory host is provided with an air supply end, a mixed air intake end and an exhalation discharge end in sequence from right to left. The air supply end is connected to the cup cover through a heated air intake pipe, and the cup cover is connected to the air supply branch pipe 1 and the air supply branch pipe 2 respectively through a Y-type joint at the front end of the heated air supply main pipe, and the exhalation discharge end is connected to the exhaust branch pipe 1 and the exhaust branch pipe 2 respectively through a Y-type joint at the front end of the exhaust main pipe; A placement table is fixedly connected to the side of the nursing bed, and four liquid accumulation cups are placed on the surface of the placement table in sequence. The exhaust branch pipe 2, the air supply branch pipe 1, the exhaust branch pipe 1 and the air supply branch pipe 2 are respectively connected to the exhaust card pipe 1, the air supply card pipe 1, the exhaust card pipe 2 and the air supply card pipe 2 through the liquid accumulation cups.

[0017] Beneficial effects of the present invention: The exhaust card tube 1 and the air supply card tube 1 form a set of air supply and breathing pipelines, and the exhaust card tube 2 and the air supply card tube 2 form another set of air supply and breathing pipelines. Thus, when the two sets of air supply and breathing pipelines are in the insulation cavity, through the isolation of the insulation cavity and the heat preservation of the phase change material or heat preservation material attached to the inner wall of the insulation cavity, the air supply and breathing pipelines are isolated from the external environment, thereby reducing the temperature inside the pipeline section reaching the dew point of condensation due to the influence of the external environment, and further causing the condensation to result in the accumulation of condensed water. And through the protective isolation of the insulation cavity, the heated and humidified gas input by the heated air supply main pipe is not likely to produce condensation during the process of being sent into the human body.

[0018] Through the cooperation of the closed loop between the return pipe and the insulation cavity and the pure water arranged inside the return pipe, when the heating element conducts heating, since the material in the area covered by the ring wrapping sleeve at the bottom of the heating cavity is a heat-conducting material, thus the heat conduction area formed by the bottom of the heating cavity relative to the ring wrapping sleeve position causes the waste heat of the heating element to heat the return pipe inside the ring wrapping sleeve and the pure water inside it, and then the waste heat of the heating element is conducted to the inside of the insulation cavity through the return pipe and the pure water inside it, thereby further maintaining the temperature inside the insulation cavity. Furthermore, through this active energy-saving waste heat utilization method, the influence of the external environment on the air supply and breathing pipelines is further reduced. And through the connection design of the return pipe and the insulation cavity, the heat source can be provided for the inside of the insulation cavity relatively energy-savingly. Thus, through the passive heat preservation of the insulation cavity and the active heat source provided by the return pipe, the influence of the external environment is further reduced, making the gas inside the pipeline not easily reach the dew point to produce condensation.

[0019] By processing the parts of the exhaust card tube 1 and the air supply card tube 1 located inside the insulation cavity, the moving drive source drives the back plate to move towards the liquid accumulation cup through the rotating rod. Then, the two rotating top wheels and the rotating bottom wheel move accordingly, and the two rotating top wheels respectively roll and squeeze the water vapor accumulation in the exhaust card tube 1 and the air supply card tube 1 during the movement, so that the accumulated water vapor is squeezed and close to the liquid accumulation cup. Finally, the possible remaining condensed water inside the exhaust card tube 1 and the air supply card tube 1 is squeezed and falls into the liquid accumulation cup.

[0020] During the movement, the bottom rod will roll and squeeze the return pipe through the rotating bottom wheel, so that the pure water inside the return pipe is squeezed and rotated towards the inside of the ring cavity, thereby increasing the contact degree between the pure water in the return pipe inside the insulation cavity and the heating element on the side of the ring cavity, promoting the internal circulation of the pure water in the return pipe, and further increasing the temperature consistency at each position inside the insulation cavity and reducing the generation of local temperature difference.

[0021] The exhaust card tube 1 and the air supply card tube 1 are also rotatably inserted into the inside of the branch header, and the branch header is clamped to the fixed column inside the heat preservation cavity through a socket, so that one end of the exhaust card tube 1 and the air supply card tube 1 is fixed. The other ends of the exhaust card tube 1 and the air supply card tube 1 are clamped to the surface through holes of the heat preservation cavity through the sleeve blocks on their surfaces. Thus, both sides of the exhaust card tube 1 and the air supply card tube 1 located on the left and right sides of the heat preservation cavity are fixed. Furthermore, when the exhaust card tube 1 and the air supply card tube 1 are squeezed, they are not prone to shaking on both sides, so it is not easy to affect the connection between the intubation end and the patient. And the buffer sleeve wraps the intubation end, which can further reduce the impact on the intubation end during the above squeezing process. During the process of removing water from the pipeline by switching between the two groups of air supply and exhalation pipelines of the exhaust card tube 1 and the air supply card tube 1 and the exhaust card tube 2 and the air supply card tube 2, the breathing supply of the patient is maintained without being affected.

[0022] The heat preservation cavity is clamped to the surface of the bed rail through the first clamping band, so that the heat preservation cavity is raised relative to the patient. And the height of the end of the heat preservation cavity close to the bed rail is lower than the height of the end of the heat preservation cavity close to the adapter, so that the condensed water is not easily refluxed into the patient's body under the traction of gravity. And a support sphere that can be inflated by opening and closing a valve is installed at the bottom of the intubation end. After the support sphere is filled with the gas output by the ventilator, the closing valve can be closed to maintain the inflated state of the support sphere. Thus, the support sphere further inflates to support the intubation end, reducing the pipeline condensation phenomenon caused by the bending of the intubation end due to gravity, making the exhaled gas of the patient more likely to enter the inside of the heat preservation cavity, and thus making it easier to heat and discharge the exhaled gas of the patient.

[0028] Refer to Figure 2 As shown, an equipment rack 103 is provided on the side of the nursing bed 101. A breathing main unit 201 is provided on the top of the equipment rack 103. A sleeve rack 104 is fixedly connected to the side of the equipment rack 103; Refer to Figure 2 and Figure 6 As shown, a heating cup body 303 is clamped inside the sleeve rack 104. A heating cavity 3032 is provided inside the heating cup body 303. A heating element 3033 is provided at the bottom of the heating cavity 3032. A cup cover 3031 is rotatably installed on the top of the heating cup body 303. A heating air inlet pipe 20111 is conductively connected to one side of the cup cover 3031, and a heating air supply main pipe 20112 is conductively connected to the other side of the cup cover 3031. An annular wrapper 301 is sleeved outside the bottom of the heating element 3033. An annular cavity 3011 is annularly provided inside the annular wrapper 301. The heating element 3033 is preferably composed of a heating resistance wire and a heat-conducting substrate, and is controlled and detected by an external power supply, a PLC, and a temperature sensor.

[0029] Operation process: By synchronously moving the equipment rack 103 and the first clamping sleeve 203, the intubation end 204 is moved to a position suitable for the patient, and then by rotating the bolt on the top of the first clamping sleeve 203, the first clamping sleeve 203 is fastened to the surface of the bed rail 102, thereby completing the adjustment of the position of the intubation end 204. Then the intubation end 204 is inserted into the trachea of the patient, and the pressing piece 2041 made of silica gel fits the sterile gauze to the skin of the patient's neck, so that the pressing piece 2041 surrounds the sterile gauze around the tracheotomy opening, and then the binding rope 2042 is knotted and fixed to the back of the patient's neck or head, and the pressing piece 2041 is attached to the patient's neck with medical adhesive tape for secondary fixation, thereby completing the connection between the patient and the ventilator.

[0030] Then turn on the breathing host 201 again, so that the gas output by the breathing host 201 enters the heating cup body 303 through the air supply end 2011. There is a heating element 3033 inside the heating cup body 303 to heat the pure water inside the heating cavity 3032, so that the pure water evaporates to heat the gas sent into the heating cavity 3032 through the heating air inlet pipe 20111. And in order to ensure the temperature and humidity suitability of the gas output from the heating cavity 3032, probes of a humidity sensor and a temperature sensor are installed in the heating air supply main pipe 20112, so as to detect the temperature and humidity of the gas heated and humidified by the heating cavity 3032, and a temperature sensor is synchronously installed in the adapter 2045 to detect the temperature of the heated gas reaching the adapter 2045 and entering the intubation end 204 after passing through the heating cavity 3032. Furthermore, by detecting the temperature change in this section and the humidity of the gas passing through the heating cavity 3032, the power of the heating element 3033 is adjusted, so that the temperature and humidity in the heating cavity 3032 are feedback controlled; The gas passing through the heating cavity 3032 will enter the inside of the first air supply branch pipe 20113 or the second air supply branch pipe 20114 through the heating air supply main pipe 20112. It should be noted that electromagnetic valves or electromagnetic proportional valves are provided at the joints of the first air supply branch pipe 20113 and the second air supply branch pipe 20114 with the heating air supply main pipe 20112 respectively, so as to control the conduction between the heating air supply main pipe 20112 and the first air supply branch pipe 20113 or the conduction between the heating air supply main pipe 20112 and the second air supply branch pipe 20114 through the electromagnetic valves. The alternate operation of the dual channels is convenient for the alternate drainage of the internal pipelines of the later-stage heat preservation cavity 202. When the electromagnetic valve between the heating air supply main pipe 20112 and the first air supply branch pipe 20113 is opened, the electromagnetic valve between the heating air supply main pipe 20112 and the second air supply branch pipe 20114 is closed. Then, the gas in the heating air supply main pipe 20112 enters the inside of the corresponding liquid accumulation cup 1012 through the first air supply branch pipe 20113, enters the branch head 2046 through the first air supply clamping pipe 2022, and enters the inside of the intubation end 204 along the adapter 2045 to supply gas to the patient.

The control members 2047 are preferably servo valves, solenoid valves or electro-hydraulic proportional valves, and are controlled by a unified PLC and powered by an external energy source.

[0034] Reference Figures 11 - 16 As shown, sleeve blocks 206 are fixedly connected to the surfaces of the observation exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023 and the air supply clamping pipe 2024; The heat preservation cavity 202 is sequentially provided with an exhaust clamping pipe 2021, an air supply clamping pipe 2022, an exhaust clamping pipe 2023, and an air supply clamping pipe 2024 along its width side direction. A partition plate 2027 is arranged between the air supply clamping pipe 2022 and the exhaust clamping pipe 2023; The sleeve block 206 is preferably made of rubber or silica gel. One ends of the exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023, and the air supply clamping pipe 2024 pass outwards from the inside of the heat preservation cavity 202 through the through holes on the side of the heat preservation cavity 202. Subsequently, the exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023, and the air supply clamping pipe 2024 are respectively pulled on the outside of the heat preservation cavity 202, so that the sleeve blocks 206 on the surfaces of the exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023, and the air supply clamping pipe 2024 approach the through holes on the side of the heat preservation cavity 202 from the inside of the heat preservation cavity 202. Finally, the sleeve blocks 206 are clamped into the through holes on the side of the heat preservation cavity 202, so that the exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023, and the air supply clamping pipe 2024 are respectively clamped into the through holes on the side of the heat preservation cavity 202 through the sleeve blocks 206; On the side of the exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023, and the air supply clamping pipe 2024 opposite to the sleeve block 206, they are rotationally threadedly inserted into the inside of the branch pipe head 2046. Then, through the clamping cooperation of the fixing column 2026 with the sleeve buckle 20461 and the fixing column 2026, the branch pipe head 2046 is fixed. Thus, the exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023, and the air supply clamping pipe 2024 on both the left and right sides of the heat preservation cavity 202 are fixed, so that the exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023, and the air supply clamping pipe 2024 are straightened inside the heat preservation cavity 202. Furthermore, it is convenient for subsequent extrusion drainage, reducing the unsmooth extrusion drainage caused by the bending of the pipeline and the blocking of the extrusion movement of the rotating top wheel 20521 by the bending of the pipeline. And the straightening of the exhaust clamping pipe 2021, the air supply clamping pipe 2022, the exhaust clamping pipe 2023, and the air supply clamping pipe 2024 also reduces the shaking of the pipeline during extrusion drainage.

[0035] Reference Figures 11 - 16As shown, backplates 205 are movably arranged on the sides of the exhaust clamping pipe 2021 and the air supply clamping pipe 2024.

The moving drive source 2057 is fixedly connected to the heat preservation cavity 202 through the bracket at its bottom. A phase change material or a heat preservation material is attached to the inner wall of the heat preservation cavity 202. The moving drive source 2057 is preferably a servo motor and is controlled by an encoder and a unified PLC chip, and is powered by an external energy source. The rotating rod 20571 is preferably a ball screw. The rotating rod 20571 is supported inside the heat preservation cavity 202 by the screw seats on both sides of it, so that the rotating rod 20571 is in transmission cooperation with the ball nut seat on the surface of the backplate 205. Or the moving drive source 2057 is preferably an electric telescopic rod or a cylinder. The moving distance of the output shaft of the moving drive source 2057 is detected by a travel switch or a pressure sensor, and is controlled by a unified PLC chip and powered by an external energy source. Thus, the moving drive source 2057 drives the backplate 205 to move through the rotating rod 20571.

[0036] Reference Figures 13 - 14 As shown, a rotating drive source 20551 is fixedly connected inside the backplate 205. The rotating drive source 20551 is preferably a servo motor and is controlled by an encoder and a unified PLC chip, and is powered by an external energy source.

[0037] Reference Figures 12 - 13As shown, on the side of the partition plate 2027, open cavity plates one 20271 are symmetrically and fixedly connected. On the side of the open cavity plate one 20271 opposite to the partition plate 2027, a connecting plate 20272 is fixedly connected. The open cavity plate one 20271 is fixedly connected to an open cavity plate three 20274 through the connecting plate 20272. At the bottom of the connecting plate 20272, an open cavity plate two 20273 is fixedly connected. The cross-sections of the open cavity plate one 20271, the open cavity plate two 20273, and the open cavity plate three 20274 are all semi-circular. The openings of the open cavity plate one 20271 and the open cavity plate three 20274 face upward, and the opening of the open cavity plate two 20273 faces downward; Inside the open cavity plate one 20271 and the open cavity plate three 20274 on one side of the partition plate 2027, an air supply clamping pipe one 2022 and an exhaust clamping pipe one 2021 are respectively clamped. Inside the open cavity plate one 20271 and the open cavity plate three 20274 on the other side of the partition plate 2027, an exhaust clamping pipe two 2023 and an air supply clamping pipe two 2024 are respectively clamped. Rotating top wheels 20521 are correspondingly arranged at the top openings of the open cavity plate one 20271 and the open cavity plate three 20274. Inside the open cavity plate two 20273, a return pipe 3022 is clamped. Rotating bottom wheels 20511 are correspondingly arranged at the bottom opening of the open cavity plate two 20273. The width of the bottom opening of the open cavity plate two 20273 is smaller than the diameter of the return pipe 3022, so that after the return pipe 3022 passes through the open cavity plate two 20273, the return pipe 3022 is not easily detached from the bottom opening of the open cavity plate two 20273; Vertical grooves 20275 are symmetrically arranged up and down on the side of the partition plate 2027. Horizontal grooves 20276 are symmetrically arranged in the middle of the side of the partition plate 2027. The vertical grooves 20275 and the horizontal grooves 20276 are conductively connected.

[0038] Reference Figures 17 - 18As shown, one side of the return pipe 3022 is looped to pass through the annular cavity 3011 and then sequentially pass through the annular jacket 301 on one side, the heat preservation jacket 3021, the heat preservation cavity 202, and the open cavity plate two 20273 on one side of the partition plate 2027. Then, it bends through the adapter 2045 and the open cavity plate two 20273 on the other side of the partition plate 2027, exits the heat preservation cavity 202, then passes through the heat preservation jacket 3021 and the annular jacket 301 on the other side, and closes and contacts the other side of the return pipe 3022 to form a closed loop. The inside of the return pipe 3022 is filled with pure water. A support sleeve 302 is sleeved on the surface of the heat preservation jacket 3021. The heat preservation jacket 3021 is preferably composed of rubber and plastic sponge or phase change material. The support sleeve 302 is preferably a rubber tube. The insertion tube end 204 on the side of the adapter 2045 does not contact the return pipe 3022, that is, the return pipe 3022 is arranged in the space between the insertion tube end 204 and the heat preservation cavity 202 to avoid the influence of the extrusion of the return pipe 3022 on the insertion tube end 204.

[0039] The rest of the structure is the same as that of the first embodiment.

[0040] Operation process: The exhaust clamping pipe one 2021 and the air supply clamping pipe one 2022 are a set of air supply and exhalation pipelines, and the exhaust clamping pipe two 2023 and the air supply clamping pipe two 2024 are another set of air supply and exhalation pipelines. Then, when the two sets of air supply and exhalation pipelines are in the heat preservation cavity 202, through the isolation of the heat preservation cavity 202 and the heat preservation of the phase change material or heat preservation material attached to the inner wall of the heat preservation cavity 202, the air supply and exhalation pipelines are isolated from the external environment, thereby reducing the temperature inside this section of the pipeline reaching the dew condensation point due to the influence of the external environment, and then generating dew condensation and causing the accumulation of condensed water. And through the protection and isolation of the heat preservation cavity 202, the heated and humidified gas input by the heating air supply main pipe 20112 is not likely to generate dew condensation during the process of being sent to the human body; Through the cooperation of the closed loop between the return pipe 3022 and the insulation cavity 202 and the pure water provided inside the return pipe 3022, when the heating element 3033 is heating, since the material in the area covered by the ring sleeve 301 at the bottom of the heating cavity 3032 is a heat-conducting material, a heat conduction area is formed at the position of the bottom of the heating cavity 3032 relative to the ring sleeve 301, so that the waste heat of the heating element 3033 heats the return pipe 3022 inside the ring sleeve 301 and the pure water inside it. Then, through the return pipe 3022 and the pure water inside it, the waste heat of the heating element 3033 is conducted to the inside of the insulation cavity 202, thereby further maintaining the temperature inside the insulation cavity 202. Furthermore, through the active energy-saving waste heat utilization method of this process, the influence of the external environment on the air supply and exhalation pipelines is further reduced. And through the connection design of the return pipe 3022 and the insulation cavity 202, the heat source can be provided to the inside of the insulation cavity 202 relatively energy-efficiently. Thus, through the passive heat preservation of the insulation cavity 202 and the active heat source supply of the return pipe 3022, the influence of the external environment is further reduced, and the gas inside the pipeline is not likely to reach the dew point to generate condensation.

[0041] In order to further reduce the condensate inside the pipeline, after the exhaust pipe clamp 1 2021 and the air supply pipe clamp 1 2022 operate for a preset time, the control member 2047 between the exhaust pipe clamp 1 2021 and the air supply pipe clamp 1 2022 and the branch header 2046 is closed. Similarly, the control valve between the exhaust branch pipe 2 20133 and the exhaust main pipe 20131 is closed, and the control valve between the air supply branch pipe 1 20113 and the heated air supply main pipe 20112 is closed, so that another group of air supply and exhalation pipelines is opened. In order to reduce the discomfort of the patient, the valve between the heated air supply main pipe 20112 and the air supply branch pipe 2 20114 is pre-opened, so that the inside of the air supply branch pipe 2 20114 and the air supply pipe clamp 2 2024 is filled with gas. Then, when the patient finishes exhaling, the valve between the air supply pipe clamp 2 2024 and the branch header 2046 is opened. Correspondingly, when the patient exhales next time, only the valve between the exhaust pipe clamp 2 2023 and the branch header 2046 is opened for exhaust; Then, by processing the parts of the exhaust pipe clamp 1-2021 and the air supply pipe clamp 1-2022 located inside the heat preservation cavity 202, the rotation drive source 20551 in the back plate 205 near the side of the exhaust pipe clamp 1-2021 is started, so that the rotation drive source 20551 drives the driving wheel 2055 to rotate. During the rotation of the driving wheel 2055, the driven strip 1-2054 and the driven strip 2-2056 will approach each other, causing the driven strip 2-2056 to move downward along the vertical groove 20275 through the ejector rod 2052, and the driven strip 1-2054 to move upward along the vertical groove 20275 through the bottom rod 2051. During the downward movement of the driven strip 2-2056, the ejector rod 2052 and the two rotating top wheels 20521 on the surface of the ejector rod 2052 will contact the exhaust pipe clamp 1-2021 and the air supply pipe clamp 1-2022 respectively, and finally the rotating top wheels 20521 will squeeze the exhaust pipe clamp 1-2021 and the air supply pipe clamp 1-2022 into the inside of the open cavity plate 1-20271 and the open cavity plate 3-20274. During this process, the bottom rod 2051 will synchronously drive the rotating bottom wheel 20511 to rise and contact the return pipe 3022, and squeeze the return pipe 3022 into the open cavity plate 2-20273 through the rotating bottom wheel 20511. At this time, both the bottom rod 2051 and the ejector rod 2052 move into the horizontal groove 20276, which is convenient for the subsequent movement of the bottom rod 2051 and the ejector rod 2052 along the horizontal groove 20276 towards the liquid collecting cup 1012. Thus, the movement drive source 2057 on the side of the exhaust pipe clamp 1-2021 is started, and the movement drive source 2057 drives the back plate 205 towards the liquid collecting cup 1012 through the rotating rod 20571. Furthermore, the two rotating top wheels 20521 and the rotating bottom wheel 20511 will move accordingly, and the two rotating top wheels 20521 will respectively roll and squeeze the water vapor aggregation in the exhaust pipe clamp 1-2021 and the air supply pipe clamp 1-2022 during the movement, so that the aggregated water vapor is squeezed closer to the liquid collecting cup 1012, and finally the condensed water that may remain in the exhaust pipe clamp 1-2021 and the air supply pipe clamp 1-2022 is squeezed and dropped into the liquid collecting cup 1012; During the movement of the bottom rod 2051, it will roll and squeeze the return pipe 3022 by rotating the bottom wheel 20511, causing the purified water inside the return pipe 3022 to be squeezed and rotated into the inside of the annular cavity 3011. Thus, the contact degree between the purified water in the return pipe 3022 in the heat preservation cavity 202 and the heating element 3033 on the side of the annular cavity 3011 is increased, promoting the internal circulation of the purified water in the return pipe 3022. Furthermore, the temperature consistency at various positions inside the heat preservation cavity 202 is further improved, reducing the generation of local temperature differences. During this process, the exhaust clamping pipe one 2021 and the air supply clamping pipe one 2022 also rotate and are inserted into the inside of the branch pipe head 2046. The branch pipe head 2046 is clamped to the fixed column 2026 inside the heat preservation cavity 202 through the socket 20461. Thus, one end of the exhaust clamping pipe one 2021 and the air supply clamping pipe one 2022 is fixed. The other ends of the exhaust clamping pipe one 2021 and the air supply clamping pipe one 2022 are clamped to the surface through holes of the heat preservation cavity 202 through the sleeve blocks 206 on their surfaces. Thus, the exhaust clamping pipe one 2021 and the air supply clamping pipe one 2022 are fixed on both the left and right sides of the heat preservation cavity 202. Therefore, when squeezing the exhaust clamping pipe one 2021 and the air supply clamping pipe one 2022, they are not prone to shaking on both sides, thus not easily affecting the connection between the insertion end 204 and the patient. The buffer sleeve 2035 wraps the insertion end 204, which can further reduce the impact on the insertion end 204 during the above squeezing process. Similarly, when the exhaust clamping pipe two 2023 and the air supply clamping pipe two 2024 operate for a preset time, they will also switch back to the operation of the exhaust clamping pipe one 2021 and the air supply clamping pipe one 2022. The rotating top wheel 20521 in the back plate 205 on the side of the air supply clamping pipe two 2024 moves and squeezes the exhaust clamping pipe two 2023 and the air supply clamping pipe two 2024 for drainage. The rotating bottom wheel 20511 at the bottom of the exhaust clamping pipe two 2023 and the air supply clamping pipe two 2024 also squeezes the water in the return pipe 3022 at the bottom of the exhaust clamping pipe two 2023 and the air supply clamping pipe two 2024 for circulation. Thus, during the process of removing water from the pipeline by switching between the two groups of air supply and exhalation pipelines, namely the exhaust clamping pipe one 2021 and the air supply clamping pipe one 2022 and the exhaust clamping pipe two 2023 and the air supply clamping pipe two 2024, the respiratory supply of the patient is maintained without being affected.

[0042] The heat preservation cavity 202 is clamped to the surface of the bed rail 102 through the clamping sleeve 203, so that the heat preservation cavity 202 is lifted relative to the patient, and the height of the end of the heat preservation cavity 202 close to the bed rail 102 is lower than the height of the end of the heat preservation cavity 202 close to the adapter 2045, so that the condensed water is not easily refluxed into the patient's body under the traction of gravity. A support sphere 2043 that can be inflated by opening and closing the valve 2044 is installed at the bottom of the intubation end 204. After the support sphere 2043 is filled with the gas output by the ventilator, the closing valve 2044 can be closed to maintain the inflated state of the support sphere 2043, so that the support sphere 2043 is further inflated to support the intubation end 204, reducing the condensation phenomenon of the pipeline caused by the bending of the intubation end 204 due to gravity, making the exhaled gas of the patient more easily enter the interior of the heat preservation cavity 202, and thus making it easier to heat and discharge the exhaled gas of the patient.
