[0031] And shunt pipe 11 right -hand member is equipped with the gas leakage air bag 14, the anti -reflux pipe 2 can be fixedly connected with shunt pipe 11 and gas leakage air bag 14,

[0032] Anti -reflux pipe 2 inside is equipped with anti -reflux flap block 3, and anti -reflux pipe 2 top is connected with first sealing sleeve 4, and anti -reflux pipe 2 bottom is connected with second sealing sleeve 5, the anti -reflux pipe 2 is fixedly connected with flow guide pipe body 1 through first sealing sleeve 4,

[0033] First sealing sleeve 4 and second sealing sleeve 5 outside are equipped with fixed bolt 6, and first sealing sleeve 4 is fixed with flow guide pipe body 1 through fixed bolt 6, and second sealing sleeve 5 bottom is connected with scale tube 10, second sealing sleeve 5 is fixedly connected with shunt pipe 11 through scale tube 10,

[0034] Shunt pipe 11 right -hand member is equipped with first outlet 12, and first outlet 12 right -hand member is connected with another set of anti -reflux pipe 2, and another set of anti -reflux pipe 2 right -hand member is connected with gas leakage air bag 14, the gas leakage air bag 14 can be connected with detection instrument, shunt pipe 11 bottom is equipped with second outlet 13, and second outlet 13 bottom is fixedly connected with threaded pipe 15, and threaded pipe 15 bottom is equipped with screw cap 16,

[0035] When using anti -reflux drainage tube, first flow guide pipe body 1 is fixedly connected with anti -reflux pipe 2, when flow guide pipe body 1 is accessed gas, makes shunt pipe 11 in terminal part connect anti -reflux flap piece 8, so that shunt pipe 11 is connected with gas leakage air bag 14, and gas leakage air bag 14 will be inflated when gas is discharged, so as to judge that gas is being discharged, when anti -reflux flap piece 8 in the anti -reflux pipe 2 can not resist backflow and cause gas backflow into the chest cavity, the force direction of gas leakage air bag 14 changes and blocks the end of shunt pipe 11, so that when gas passes through flow guide pipe body 1, the gas pressure intensity can be detected by gas leakage air bag 14 connected at the end of shunt pipe 11, so that the user can observe more conveniently,

[0036] When flow guide pipe body 1 is connected with anti -reflux pipe 2, first sealing sleeve 4 can be sealingly connected with the bottom of flow guide pipe body 1, and then flow guide pipe body 1 is fixedly connected with first sealing sleeve 4 through fixed bolt 6.

[0037] Example 2:

[0038] This embodiment discloses another anti-backflow tube 2 structure, which differs from that of Embodiment 1, as follows: Figure 4 As shown, the difference between this embodiment and embodiment 1 is that: the anti-backflow tube 2 is provided with a first fixed filter yarn 7 inside, and the bottom of the first fixed filter yarn 7 is fixedly connected to an anti-backflow valve 8, and the bottom of the anti-backflow valve 8 is fixedly connected to a second fixed filter yarn 9. Both the first fixed filter yarn 7 and the second fixed filter yarn 9 are fixedly connected to the anti-backflow tube 2.

[0039] When the gas passes through the anti-backflow tube 2, the first fixed filter yarn 7 and the second fixed filter yarn 9 will filter the dust inside the gas, thereby preventing dust from contaminating the anti-backflow valve 8 and increasing the protection of the device.

[0040] Working principle: When using the anti-reflux drainage tube, firstly, the guide tube body 1 is fixedly connected to the anti-reflux tube 2. When gas is introduced into the guide tube body 1, the anti-reflux valve 8 is connected to the end of the diversion tube 11, thereby connecting the diversion tube 11 to the leaking air bag 14. When gas is discharged, the leaking air bag 14 will inflate, thus indicating that gas is being discharged. When the anti-reflux valve 8 inside the anti-reflux tube 2 fails to prevent backflow and causes gas to be drawn back into the pleural cavity, the direction of force on the leaking air bag 14 changes and blocks the end of the diversion tube 11. Thus, when gas passes through the guide tube body 1, the air pressure intensity can be detected by the leaking air bag 14 connected to the end of the diversion tube 11, making it easier for the user to observe.

[0041] When the guide tube body 1 is connected to the anti-backflow tube 2, it can be sealed to the bottom of the guide tube body 1 through the first sealing sleeve 4, and then the guide tube body 1 and the first sealing sleeve 4 can be fixedly connected by the fixing bolt 6.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
