Lung function training device for respiratory medicine department

[0027] Example

[0028] See Figure 1-Figure 3 , The present invention provides a lung function training device for respiratory medicine. Its structure includes a telescopic breathing tube 1, a connecting tube 2, an air intake tube 3, a connecting tube 4, a control valve 5, a chassis 6, a step display system 7, and the chassis 6 A ladder display system 7 is provided on the top surface. An intake pipe 3 is installed on the chassis 6 on one side of the ladder display system 7, and a control valve 5 is provided between the intake pipe 3 and the ladder display system 7. It is provided with a connecting tube 4, the connecting tube 4 and the trachea 3 are connected together, the side of the connecting tube 4 is horizontally installed with a connecting small tube 2, and the end of the connecting small tube 2 is nested with a telescopic breathing tube 1. The tube 1 is movably connected to the patient's oral cavity.

[0029] The ladder display system 7 is provided with a communicating device 71, a third transparent tube 72, a second transparent tube 73, a first transparent tube 74, a balloon 75, and an inflator 76, the third transparent tube 72, the second transparent tube 73. The first transparent tube 74 is arranged on the top surface of the chassis 6 from left to right, the first transparent tube 74 is adjacent to the air inlet tube 3, and the top of the second transparent tube 73 and the first transparent tube 74 communicate The first transparent tube 74 communicates with the bottom of the air inlet pipe 3 through an air receiver 76. The air receiver 76 is equipped with a control valve 5, and the bottom of the third transparent tube 72 and the second transparent tube 73 They are connected by an inflator 76, the third transparent tube 72, the second transparent tube 73, and the first transparent tube 74 are provided with a balloon 75 inside, and the balloon 75 is connected to the third transparent tube 72 and the second transparent tube 73. And the first transparent tube 74 adopts active coordination.

[0030] The three transparent tubes 72, the second transparent tube 73 and the first transparent tube 74 have the same size and height.

[0031] The ball diameter of the balloon 75 is smaller than the cross-sectional diameter of the third transparent tube 72, the second transparent tube 73, and the first transparent tube 74, which facilitates the floating movement of the balloon 75 up and down without being blocked.

[0032] The communicating device 71 is provided with a U-shaped tube 711, a connecting tube 712, and a floating plug 713. The U-shaped tube 711 is placed upside down. The bottom ends of the U-shaped tube 711 are equipped with connecting tubes 712. The bottom of the connecting tube 712 is embedded in the top of the second transparent tube 73 and the top of the first transparent tube 74, and the connecting tube 712 connected to the first transparent tube 74 is provided with a floating plug 713. The floating plug 713 is connected to this The tube 712 adopts a sliding fit.

[0033] The floating plug 713 has an inverted T-shaped structure. The horizontal length of the horizontal end of the floating plug 713 is smaller than the inner diameter of the connecting pipe 712. The vertical end of the floating plug 713 has a wide upper and narrow structure. Once the floating plug 713 rises, The gas will enter the U-shaped tube 711 from both sides of the horizontal end of the floating plug 713, ensuring the connectivity of the second transparent tube 73 and the first transparent tube 74.

[0034] The air receiver 76 is provided with a caulking 761, a top tube 762, a support block 763, and a through tube 764. The caulking opening 761 is opened on the chassis 6 and a top tube 762 is provided in the middle of the caulking 761. The inner wall of the caulking 761 is provided with more than two support blocks 763, these support blocks 763 are circular and equidistantly distributed, the bottom of the top pipe 762 is equipped with a through pipe 764, and the other end of the through pipe 764 is connected to another air holder The bottom of the top pipe 762 of 76 is connected.

[0035] The height of the top tube 762 is lower than the height of the support block 763, and the height difference between the two is used to form a stable base, which is convenient for the balloon 75 to be placed without rolling around.

[0036] When in use, the control valve 5 is opened, and the telescopic breathing tube 1 is placed into the patient’s mouth. In the breathing room, the exhaled air passes through the intake tube 3 and the inflator 76 installed with the control valve 5, and enters the first transparent tube 74. The balloon 75 in the transparent tube 74 rises, and the balloon 75 rises to the highest point. The balloon 75 rises to lift the floating plug 713. The floating plug 713 adopts a design with a wide upper and a narrow bottom. When the floating plug 713 rises, the gas will Enter the U-shaped tube 711 from both sides of the horizontal end of the floating plug 713 to ensure the connectivity of the second transparent tube 73 and the first transparent tube 74. Breathing gas enters the second transparent tube 73, allowing the balloon 75 in the tube to rise, and then , Connect the inflator 76 between the third transparent tube 72 and the second transparent tube 73, and the balloon 75 in the third transparent tube rises to top it, so that breathing gas may enter the third transparent tube 72 , Let the balloon 75 in the tube rise, realize the objective change of breathing intensity, and also facilitate observation. In this process, first, the inflator 76 not only serves as a connected trachea, but also uses the gap between the top tube 762 and the branch 763. The height difference forms a stable base, which is convenient for the balloon 75 to be placed without rolling around. Second, the diameter of the balloon 75 is smaller than the cross-sectional diameter of the third transparent tube 72, the second transparent tube 73, and the first transparent tube 74, which is convenient for the balloon 75 to go up and down. Levitating movement will not be blocked.
