DETAILED DESCRIPTION

[0026] The specific embodiment is a kind of atomization inhalation device with closed sputum suction tube, its structure schematic view as shown in Figures 1-7 The inhalation device includes tracheal cannula 1, and the one end of tracheal cannula 1 is provided with transverse connecting pipe 2, and the one side of transverse connecting pipe 2 is equipped with Y-shaped shunt pipe 3, and the one end of transverse connecting pipe 2 is equipped with sputum suction assembly;

[0027] Through the setting of Y-shaped shunt pipe 3, oxygen, air or atomized drug can enter the inside of tracheal cannula 1 through Y-shaped shunt pipe 3 and transverse connecting pipe 2, and then can enter the body of patient;

[0028] The outside of the one end of transverse connecting pipe 2 is sleeved with circular fixing ring 23, and the outside of circular fixing ring 23 is fixed with U-shaped connecting strip 24, and the one end of U-shaped connecting strip 24 is provided with circular sealing cover 22 adapted with transverse embedded pipe 21, when circular sealing cover 22 is installed to the outside of transverse embedded pipe 21, gas leakage can be prevented through transverse embedded pipe 21;

[0029] The suction assembly includes a Y-shaped shunt tube 3, with a rigid tube 5 inside the Y-shaped shunt tube 3. A first flexible tube 6 is provided at one end of the rigid tube 5, and a suction tube 11 is provided at the other end of the rigid tube 5. The other end of the Y-shaped shunt tube 3 is sleeved on the outside of the transverse embedded tube 21. A circular cover 7 is fixed to the bottom of one end of the first flexible tube 6. A liquid storage tank 8 is provided at the bottom of the circular cover 7, and an L-shaped connecting tube 9 is provided at one end of the top of the circular cover 7.

[0030] A sealing ring is provided on the outer side of the top of the liquid storage tank 8, and a sealing groove adapted to the sealing ring is provided inside the circular cover 7. The circular cover 7 and the liquid storage tank 8 are fitted together by the sealing ring and the sealing groove. The sealing ring and the sealing groove enable the circular cover 7 and the liquid storage tank 8 to be better connected, improve the connection strength between the circular cover 7 and the liquid storage tank 8, and improve the sealing performance of the circular cover 7 and the liquid storage tank 8.

[0031] Here, the L-shaped connecting tube 9 is connected to the negative pressure machine, and then the reservoir 8 is installed at the bottom of the circular cover 7. Then, the rigid tube 5 is pushed. The movement of the rigid tube 5 causes the transverse telescopic sterile tube 4 to contract under force, so that the suction tube 11 can enter the endotracheal tube 1 through the transverse connecting tube 2 and move out of the endotracheal tube 1, so that the suction tube 11 can enter the patient's larynx. Through the operation of the negative pressure machine, a negative pressure is generated inside the reservoir 8, so that the sputum in the patient's larynx can enter the suction tube 11 and be injected into the reservoir 8 through the suction tube 11.

[0032] A transverse connecting ring 13 is provided at one end of the Y-shaped diverter 3 and outside the rigid pipe 5. A circular rotary knob 10 is threaded to the outside of the transverse connecting ring 13. An annular compression ring 14 is fixed inside the circular rotary knob 10. A conical fitting block 12 is provided at one end of the Y-shaped diverter 3 and inside the annular compression ring 14. Through the arrangement between the annular compression ring 14 and the conical fitting block 12, when the circular rotary knob 10 is connected to the transverse connecting ring 13, the movement of the annular compression ring 14 causes the conical fitting block 12 to deform, so that the conical fitting block 12 can fit with the rigid pipe 5, thereby allowing the rigid pipe 5 to be fixed inside the Y-shaped diverter 3.

[0033] The Y-shaped shunt tube 3 has a circular through hole inside. The rigid tube 5 is located inside the circular through hole and is slidably connected to the Y-shaped shunt tube 3 through the circular through hole. The circular through hole allows the rigid tube 5 to slide laterally inside the Y-shaped shunt tube 3, so that the suction tube 11 can move out of the Y-shaped shunt tube 3.

[0034] The outer side of the transverse connecting ring 13 is provided with an internal thread, and the circular rotary knob 10 is provided with an external thread on the outer side of the transverse connecting ring 13. The circular rotary knob 10 and the transverse connecting ring 13 are connected by the internal and external threads. The internal and external threads allow the circular rotary knob 10 to be fixed on the outer side of the transverse connecting ring 13, thereby allowing the annular extrusion ring 14 to move toward the conical bonding block 12. The movement of the annular extrusion ring 14 causes the conical bonding block 12 to be deformed by force.

[0035] The annular extrusion ring 14 has a conical surface inside that matches the conical fitting block 12. The conical fitting block 12 is made of rubber, which is a polymer material with elasticity, extensibility, and compressibility. The elasticity of rubber allows it to recover its original shape after being stretched or compressed. This characteristic makes it important for applications in sealing, shock absorption, and buffering. Furthermore, the conical surface allows the conical fitting block 12 to deform, so that the inner side of the conical fitting block 12 can be tightly attached to the rigid pipe 5, preventing the rigid pipe 5 from moving inside the Y-shaped diversion pipe 3.

[0036] When it is necessary to replace the suction tubing 11, rotate the circular knob 10. When the circular knob 10 rotates out of the outer side of the transverse connecting ring 13, the compression between the annular compression ring 14 and the conical fitting block 12 is released, allowing the rigid tube 5 to move inside the Y-shaped diversion tube 3. This allows the suction tubing 11 to be pulled out of the Y-shaped diversion tube 3, facilitating subsequent replacement of the suction tubing 11. This prevents cells and organic matter in the sputum from remaining inside the suction tubing 11 due to repeated use, which could become a breeding ground for bacteria.

[0037] Through a series of designs, the suction tubing 11 can be deeply inserted into the patient's throat to suction sputum while maintaining an uninterrupted oxygen supply, thus improving treatment efficiency. Moreover, the suction tubing 11 is designed to be located inside a sterile, horizontally retractable sterile tube 4, and the suction tubing 11 is easy to replace, thereby avoiding the risk of bacterial growth and ensuring that patients receive safer and more efficient care during treatment.

[0038] Working principle: When using the inhalation device of this technical solution, connect the L-shaped connecting tube 9 to the negative pressure machine, then install the reservoir 8 at the bottom of the circular cover 7, and then push the rigid tube 5. The movement of the rigid tube 5 causes the transverse telescopic sterile tube 4 to contract under force, so that the suction tube 11 can enter the interior of the endotracheal tube 1 through the transverse connecting tube 2 and move out of the interior of the endotracheal tube 1, so that the suction tube 11 can enter the interior of the patient's larynx. Through the operation of the negative pressure machine, a negative pressure is generated inside the reservoir 8, which allows the sputum in the patient's larynx to enter the interior of the suction tube 11 and be injected into the interior of the reservoir 8 through the suction tube 11.

[0039] When the suction tubing 11 needs to be replaced, rotate the circular knob 10. When the circular knob 10 rotates out of the outer side of the transverse connecting ring 13, the compression between the annular compression ring 14 and the conical fitting block 12 is released, allowing the rigid tube 5 to move inside the Y-shaped diversion tube 3. This allows the suction tubing 11 to be pulled out of the Y-shaped diversion tube 3, facilitating subsequent replacement of the suction tubing 11. This prevents cells and organic matter in the sputum from remaining inside the suction tubing 11 due to repeated use, which could become a breeding ground for bacteria.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
