[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 2 to 4 The utility model provides an embodiment: a disposable, disposable granular water-absorbing bag for a respirator, comprising a water-absorbing bag 1, which is used to dry the gas transmitted from the respirator. A water-absorbing granular layer 2 is provided inside the water-absorbing bag 1, which is used to absorb moisture in the gas. A threaded joint 3 is fixedly connected to the top of the water-absorbing bag 1. The design of the threaded joint 3 ensures that it can be firmly connected to other components of the respirator to avoid gas leakage, while facilitating the timely replacement of the water-absorbing bag 1. The outer side of the threaded joint 3 is threadedly connected to a sleeve 4, and the inner wall of the sleeve 4 is fixedly connected to a connecting pipe 6, which is used to connect the gas transport pipeline of the respirator and the water-absorbing bag 1. The inner wall of the sleeve 4 is fixedly connected to a sealing ring 5, and the inner wall of the sealing ring 5 is in contact with the outer wall of the connecting pipe 6. The sealing ring 5 is used to prevent gas leakage and effectively prevent the intrusion of external pollutants.

[0033] The other end of the connecting pipe 6 is fixedly connected to the air intake pipe 7, and the inner wall of the air intake pipe 7 is slidably connected to the air intake valve 9. The outer wall of the air intake valve 9 is fixedly connected to a plurality of sliders 8. The design of the sliders 8 ensures the flexible operation of the air intake valve 9, making the opening and closing of the air flow smoother. The outer walls of the plurality of sliders 8 are slidably connected to the inner wall of the air intake pipe 7. A plurality of air intake holes 10 are provided on the outside of the air intake valve 9, and the air intake holes 10 are used to allow air to enter the ventilator system efficiently. One end of the air intake pipe 7 is fixedly connected to a ventilation cylinder 11. The design of the ventilation cylinder 11 is intended to improve the gas exchange efficiency so that the patient can obtain sufficient fresh air. The interior of the ventilation cylinder 11 is fixedly connected to a check assembly for preventing the condensation and backflow of the patient's exhaled gas.

[0034] The check assembly includes an air outlet pipe 12, the outer wall of which is fixedly connected to the inside of the ventilator 11 to ensure that the exhaled gas can be discharged smoothly. A connecting pipe 2 17 is fixedly connected to the inside of the air outlet pipe 12, and the other end of the connecting pipe 2 17 is used to connect to a collection mechanism that collects condensed water from the patient's exhaled gas to prevent backflow, thereby ensuring that the moisture in the exhaled gas is effectively collected and avoiding potential damage to the equipment by condensed water. A fixed ring 13 is fixedly connected to the inner wall of the air outlet pipe 12, and an air outlet valve 15 is slidably connected to the inner wall of the fixed ring 13. The outer wall of the air outlet valve 15 is fixedly connected to multiple sliders 2 14. The exhaled gas drives the air outlet valve 15 to move toward the inside of the air outlet pipe 12, opening the air outlet valve 15 and allowing the exhaled gas to be discharged smoothly. The outer walls of the multiple sliders 2 14 are slidably connected to the inner wall of the fixed ring 13 to ensure that the air outlet valve 15 can move smoothly. A plurality of air outlet holes 16 are formed on the outside of the air outlet valve 15 . The air outlet holes 16 are exposed by the movement of the air outlet valve 15 , so that the exhaled gas enters the air outlet pipe 12 .

[0035] An air supply tube 18 is fixedly connected to the interior of the ventilator 11. The other end of the air supply tube 18 is directly connected to the patient's respiratory system, thereby maintaining normal breathing. The mid-ends of the air supply tube 18, the air inlet tube 7, and the air outlet tube 12 are all equipped with bending sections 19 to facilitate pipe bending and extension. This allows the air inlet tube 7, the air outlet tube 12, and the air supply tube 18 to be bent and extended according to different situations, thereby adapting to different usage requirements. A fixing assembly is fixedly connected to the outer wall of the air inlet tube 7, which is used to secure the air inlet tube 7 to the bedside.

[0036] Reference Figure 1 、 Figure 2 、 Figure 5 The fixing assembly includes a collar 20, the inner wall of which is fixedly connected to the outer wall of the air inlet pipe 7. The collar 20 is used to fix the fixing assembly to the air inlet pipe 7 of the ventilator to ensure stability. A fixing block 21 is fixedly connected to the bottom of the collar 20, and a fixing buckle 22 is fixedly connected to the bottom of the fixing block 21. The fixing block 21 serves to connect the fixing buckle 22 and the collar 20, and the fixing buckle 22 is used to fix the entire device to the patient's bedside for easy use. The two ends of the fixing buckle 22 are internally threaded with screws 23, one end of the screw 23 is fixedly connected to a handle 24, and the outer side of the screw 23 is threaded with a fastening ring 25. By turning the handle 24, the screw 23 is driven to rotate, thereby driving the two ends of the fixing buckle 22 to close together, and further reinforced by the fastening ring 25, so that the connection between the air inlet pipe 7 and the patient's bedside is stable.

[0037] Working Principle: When a patient exhales, the exhaled gas flows through the inlet tube 7 and into the connecting tube 1 6. The water in the gas is absorbed by the absorbent particle layer 2 in the water-absorbing bag 1 before flowing into the interior of the ventilator 11. During this process, the inlet valve 9, under pressure from the gas, moves toward the ventilator 11, connecting the inlet hole 10 with the interior of the ventilator 11. This allows the gas to enter the ventilator 11 and pass into the air delivery tube 18. When the patient exhales, the inlet valve 9 moves in the opposite direction, isolating the inlet hole 10 from the interior of the ventilator 11. This prevents the exhaled gas from flowing back into the inlet tube 7 and instead directs it to the outlet tube 12. This drives the outlet valve 15 toward the outlet tube 12, connecting the outlet hole 16 with the outlet tube 12. This allows the exhaled gas to enter the outlet tube 12 and enter the collection mechanism through the connecting tube 2 17. This effectively separates and processes the patient's exhaled and inhaled air within the ventilator 11.

[0038] Then, by putting the fixing buckle 22 on the patient's bedside and turning the screw 23, the two ends of the fixing buckle 22 are moved closer to the middle, thereby clamping the patient's bedside, and then the connection between the fixing buckle 22 and the patient's bedside is further strengthened by turning the fastening ring 25, so as to fix the ventilator outlet pipe 12 to the patient's bedside.

[0039] After using the respirator, the water absorption bag 1 can be taken out for processing by rotating the water absorption bag 1, and the water absorption bag 1 can be quickly replaced by connecting a new water absorption bag 1 to the sleeve 4.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
