The chest drainage device is generally composed of a liquid accumulation cavity, a water seal cavity, a pressure regulating cavity, a drainage tube extension pipe and a connector, and is divided into two-cavity, three-cavity and four-cavity types according to different structures. When the chest drainage device is used, the liquid is connected to the drainage site in the patient's body through the drainage tube, and under the action of negative pressure, the liquid is smoothly discharged out of the patient's body. The liquid level in the negative pressure tank and the negative pressure controller can adjust the negative pressure and the height of the liquid level, so as to control the effect of drainage and the negative pressure, help to rebuild and maintain the normal intrathoracic pressure, assist to complete the lung redilation and restore the normal respiratory power.
[0004] At present, the chest drainage device is generally used with a negative pressure tank or a suction pump to suck. In the suction process, it is inconvenient to adjust the suction force according to the actual situation, the air pressure is insufficient, the gas-liquid can flow back when the patient coughs violently, the risk of lung infection is increased, the cavity will be invalid after tilting and cause a medical accident, the water seal cavity needs to be filled with water before use, it is inconvenient to carry and is not conducive to the patient to walk out of bed, the air exhaust resistance is large after adding water, it is not conducive to the use of children, weak patients and other people with difficulty in air exhaust, and the multi-cavity type drainage device will produce the noise of water bubble boiling when the negative pressure suction air flow is too large, which affects the rest and recovery of the patient.

DETAILED DESCRIPTION
[0030] In order to better understand the purpose, structure and function of the utility model, below, combining with the drawings, a kind of pneumothorax treatment device of the utility model is further described in detail.
[0031] As Figure 1 The utility model discloses a pneumothorax treatment device, including check valve 1, catheter 2, gas water separation device 3, piston assembly 4, waste liquid bag assembly 5. Gas water separation device 3 includes chamber one 321 and chamber two 322, and catheter 2 includes catheter one 21, catheter two 22 and catheter three 23, check valve 1 includes check valve one 11 and check valve two 12, check valve one 11 is connected with the chamber one of gas water separation device 3 by catheter one 21, for the one-way input gas liquid into gas water separation device 3, check valve two 12 is connected with the chamber two of gas water separation device 3 by catheter two 22, for discharging gas, piston assembly 4 is connected with the chamber two of gas water separation device 3, for adjusting gas pressure, waste liquid bag assembly 5 is connected with piston assembly 4 by catheter three 23, for collecting waste liquid.
[0032] As Figure 2As shown, the one-way valve 1 is made of a polymer material, which can be, but is not limited to, polypropylene (PP). The opening pressure is ≤0.05 kPa, and the ideal opening pressure is 200-300 Pa. The upper end of the one-way valve 11 is the inlet end 111, the middle is a diaphragm 112, and the lower end is the outlet end 113. There are movable spaces below both ends of the diaphragm 112. Gas and liquid flow in from the upper end of the diaphragm 112, and under the action of pressure, they break through the diaphragm 112 and flow out from the movable space around the diaphragm 112, finally flowing out from the outlet end 113 at the lower end of the one-way valve 11. Conversely, if the diaphragm 12 blocks the inlet, it cannot flow out. Gas and liquid flow in from the inlet end 111, then flow out from around the diaphragm 112, and finally flow out along the outlet end 113, as shown. Figure 2 The arrow points in the direction of the gas-liquid flow. This prevents backflow of gas and liquid. The inlet 111 of check valve 1 connects to the tube inserted into the human body, and the outlet 113 connects to conduit 21. The direction of check valve 2 12 is opposite to that of check valve 1 11; gas flows out from bottom to top, and vice versa. This prevents external air from entering the gas-liquid separator 3.
[0033] The catheter 2 is made of a polymer material, which may be, but is not limited to, PEBAX material, with a hardness of 90-95A.
[0034] like Figure 3 As shown, the gas-liquid separator 3 includes a gas-liquid separator cap 31 and a gas-liquid separator bottle 32. The gas-liquid separator cap 31 is made of a polymer material, which may be, but is not limited to, ABS plastic.

The outlet end of the gas outlet 312 is outward to prevent external air from entering the gas-water separation bottle 32. When the gas-water separation device 3 is placed horizontally to the left, the gas-liquid mainly flows out from the bottom of the trumpet-shaped opening 3211. The inclined plate on the left side of the channel 3213 can retain part of the liquid, ensuring that the liquid mainly flows out from the bottom of the trumpet-shaped opening 3211, and a very small amount of gas-liquid flows out from the channel 3213.

The port of the catheter three 23 is flush with the piston body supplement 42 and is fixedly connected, such as glue connection.
[0040] The piston assembly 4 is inserted into the bottom of the second chamber of the gas-water separation device 3, and the pressure in the gas-water separation device 3 is controlled by the piston assembly 4. Under a certain pressure, most of the gas-liquid enters the waste liquid bag assembly 5 along the third conduit 23 through the gas outlet 312.
[0041] As shown in Figure 6 The waste liquid bag assembly 5 includes a waste liquid bag 51 and a waterproof air valve 52. The upper end of the waste liquid bag 51 is fixedly connected with the third conduit 23, and the waterproof air valve 52 is fixedly installed on the side of the waste liquid bag 51, such as glue curing connection, embedded injection molding, etc. The waste liquid bag 51 is made of a high polymer material, including but not limited to polypropylene (PP).
