[0003] Existing breathing training devices have simple structures and cannot effectively assist patients in recovery, thus affecting the speed of recovery to some extent.
[0004] To address the above problems, this utility model provides a respiratory training aid for critical care patients. Utility Model Content
[0005] The purpose of this invention is to provide a respiratory training aid for critically ill patients, which assists patients in recovery by blowing air into liquids of different densities, thereby solving the problems in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a respiratory training assist device for critical care patients, comprising a base, a column fixedly mounted at the upper center of the base, a rotating ring rotatably mounted on the outer side of the column, and multiple evenly distributed transparent tubes circumferentially mounted on the outer side of the rotating ring, each transparent tube containing a certain amount of liquid of different densities, with graduations on the outer side of the transparent tubes, a connecting pipe fixedly connected to the bottom end of the transparent tubes, a one-way valve fixedly mounted on the connecting pipe, an air inlet pipe fixedly mounted at the middle of the upper edge of the base, an annular groove coaxially opened on the upper surface of the air inlet pipe, an annular plate mounted in the annular groove, a spring mounted at the lower end of the annular plate, and a flexible hose mounted at the air inlet end of the air inlet pipe, the air inlet end of the flexible hose being connected to an external breathing mask.
[0007] Furthermore, the inner side of the rotating ring is rotatably connected to the upper outer side of the column via a bearing, and a connecting plate is fastened between the outer side of the transparent tube and the outer side of the rotating ring.
[0008] Furthermore, the annular plate slides against the inner side of the annular groove, and multiple evenly distributed springs are fixedly connected to the bottom surface of the annular groove in a circumferential direction. The upper ends of the springs are fixedly connected to the bottom end of the annular plate, and the upper end structure of the annular plate is located on the outer side of the upper end of the intake pipe in the initial state.
[0009] Furthermore, a limiting ring is fixedly provided on the outer side of the lower end of the connecting pipe, and a sealing gasket is fixedly provided at the bottom end of the limiting ring. The inner side of the annular plate slides in contact with the outer side of the connecting pipe, and the spring drives the upper end of the annular plate to press and contact the bottom end of the sealing gasket.
[0010] Furthermore, a protrusion is fixedly connected to the lower outer end of the air intake pipe, and an air intake hole is opened in the middle of the side of the protrusion, which is connected to the inside of the air intake pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model provides a respiratory training aid for critically ill patients. The annular plate is manually pressed downwards, moving downwards within an annular groove and compressing a spring. Simultaneously, a rotating ring is manually rotated, causing multiple transparent tubes to rotate synchronously around a column. When one of the transparent tubes rotates to align with the inlet tube, the annular plate is released. Under the spring's restoring deformation, the annular plate moves upwards and fits onto the outside of the connecting tube. At this point, the inlet tube connects to the transparent tube. A breathing mask is then placed on the patient's face, and the oxygen delivery tube is connected to an oxygen concentrator. The patient can then inhale oxygen through the oxygen delivery tube and breathing mask. Exhaled air is delivered through a flexible tube to the inside of the inlet tube, and subsequently, the air enters the transparent tube through the connecting tube. The liquid inside the transparent tube rises upwards, and its height can be observed using a scale. A one-way valve prevents liquid backflow. Different transparent tubes can be connected to the inlet tube during this process, allowing for the blowing of air into liquids of different densities. By observing the height of the airflow, lung capacity can be trained. The purpose of this design is to assist patient recovery through training with the blowing of air into liquids of different densities. Attached Figure Description

[0020] To address the issue of how to effectively train breathing techniques, such as... Figure 1-4 As shown, the following preferred technical solutions are provided:
[0021] A respiratory training aid for critical care patients includes a base 1. A column 17 is fixedly mounted on the upper middle part of the base 1. A rotating ring 16 is rotatably mounted on the outer side of the column 17. Multiple transparent tubes 13 are evenly distributed around the outer circumference of the rotating ring 16. Each transparent tube 13 contains a certain amount of liquid of different densities. A scale value 14 is set on the outer side of the transparent tube 13. A connecting pipe 9 is fixedly connected to the bottom end of the transparent tube 13. A one-way valve 10 is fixedly installed on the connecting pipe 9. An air inlet pipe 2 is fixedly mounted on the upper edge of the base 1. An annular groove 3 is coaxially opened on the upper end face of the air inlet pipe 2. An annular plate 5 is set in the annular groove 3. A spring 4 is set at the lower end of the annular plate 5. A hose 8 is set at the air inlet end of the air inlet pipe 2. The air inlet end of the hose 8 is connected to an external breathing mask.
[0022] Specifically, manually press down on the annular plate 5. The annular plate 5 moves downward within the annular groove 3 and compresses the spring 4. At the same time, manually rotate the rotating ring 16, causing multiple transparent tubes 13 to rotate synchronously around the column 17. When one of the transparent tubes 13 rotates to be coaxially aligned with the air inlet tube 2, release the annular plate 5. Under the push of the spring 4's return deformation, the annular plate 5 moves upward and is fitted onto the outside of the connecting tube 9. At this time, the air inlet tube 2 is connected to the transparent tube 13. Then, put the breathing mask on the patient's face and connect the oxygen delivery tube to the oxygen concentrator. At this time, the patient can inhale oxygen through the oxygen delivery tube and breathing mask, and the exhaled gas can be delivered to the inside of the air inlet tube 2 through the hose 8. Subsequently, the gas enters the transparent tube 13 through the connecting tube 9. The liquid in the transparent tube 13 moves upward. The height can be observed through the scale value 14. The one-way valve 10 prevents the liquid from flowing back. During this period, different transparent tubes 13 can be connected to the air inlet tube 2 to blow air into liquids of different densities. By observing the height, lung capacity can be trained. The purpose of this design is to assist patients in their recovery through air-blowing training with liquids of different densities.
[0023] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0024] The inner side of the rotating ring 16 is rotatably connected to the upper outer side of the column 17 via a bearing. A connecting plate 15 is fastened between the outer side of the transparent tube 13 and the outer side of the rotating ring 16. The purpose of this design is to ensure that the rotation of the rotating ring 16 can drive multiple transparent tubes 13 to rotate synchronously around the column 17.
[0025] Furthermore, such as Figure 2 and Figure 4 As shown, the following preferred technical solutions are provided:
[0026] The annular plate 5 slides against the inner side of the annular groove 3. Multiple evenly distributed springs 4 are fixedly connected to the bottom surface of the annular groove 3. The upper end of the spring 4 is fixedly connected to the bottom end of the annular plate 5. In the initial state, the upper end structure of the annular plate 5 is located on the outer side of the upper end of the air intake pipe 2. The purpose of this design is to ensure that the annular plate 5 can move vertically and can be connected to the transparent pipe 13 under the push of the spring 4.
[0027] Furthermore, such as Figure 2 and Figure 4 As shown, the following preferred technical solutions are provided:
[0028] A limiting ring 11 is fixedly installed on the outer side of the lower end of the connecting pipe 9, and a sealing gasket 12 is fixedly installed at the bottom end of the limiting ring 11. The inner side of the annular plate 5 slides against the outer side of the connecting pipe 9. The spring 4 drives the upper end of the annular plate 5 to press against the bottom end of the sealing gasket 12. The purpose of this design is to ensure that the air inlet pipe 2 and the connecting pipe 9 are connected through the annular plate 5 without leakage.
[0029] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:
[0030] A protrusion 6 is fixedly connected to the lower outer side of the air inlet pipe 2. An air inlet hole 7 is opened in the middle of the side of the protrusion 6, which is connected to the inside of the air inlet pipe 2. The air inlet end of the air inlet hole 7 is fixedly connected to the air outlet end of the hose 8. The purpose of this design is to allow the patient's exhaled air to enter the air inlet pipe 2 through the hose 8.
[0031] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0032] The bottom of the base 1 is fitted with an anti-slip pad, which is designed to improve the stability of the base 1.
[0033] In summary: Manually press down on the annular plate 5. The annular plate 5 moves downward within the annular groove 3 and compresses the spring 4. Simultaneously, manually rotate the rotating ring 16, causing multiple transparent tubes 13 to rotate synchronously around the column 17. When one of the transparent tubes 13 rotates to be coaxially aligned with the air inlet pipe 2, release the annular plate 5. Under the push of the spring 4's return to its original deformation, the annular plate 5 moves upward and is fitted onto the outside of the connecting pipe 9. At this time, the air inlet pipe 2 is connected to the transparent tube 13. Then, put the breathing mask on the patient's face and connect the oxygen delivery tube to the oxygen concentrator. At this time, the patient can inhale oxygen through the oxygen delivery tube and breathing mask, and the exhaled gas can be delivered to the inside of the air inlet pipe 2 through the hose 8. Subsequently, the gas enters the transparent tube 13 through the connecting pipe 9. The liquid in the transparent tube 13 moves upward. The height can be observed through the scale value 14. The one-way valve 10 prevents liquid backflow. During this period, different transparent tubes 13 can be connected to the air inlet pipe 2 to blow air into liquids of different densities. By observing the height, lung capacity can be trained. The purpose of this design is to assist patients in their recovery through air-blowing training with liquids of different densities.
