[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. In the scheme of the present application, an inflation assembly is provided so that the first airbag is fixed at the lateral chest of the patient. When the patient is in a supine position, the first airbag located at the lateral chest is not squeezed, and the second airbag does not expand at this time. When the patient changes from a supine position to a lateral position, when the opening of the deflation switch is in a smaller state, as the patient turns sideways, the first airbag is squeezed by the bed and the lateral chest, so that the gas in the first airbag is squeezed to the second airbag and the deflation switch through the inflation tube. Since the opening of the deflation switch is small, the amount of gas flowing out of the deflation switch in a short time is small, and most of the gas enters the second airbag, causing the second airbag to expand. , so that the expanded second airbag supports the drainage tube body, so that when the patient's body is pressed on the drainage tube body, the drainage tube body can be prevented from being flattened, thereby improving the pressure resistance of the drainage tube body, thereby reducing the risk of chest drainage tube being crushed, and after the second airbag is expanded, the second airbag can occupy the flow space in the drainage tube for the circulation of drainage fluid in a short time, so that the expanded second airbag can provide impact force to impact the drainage fluid in the drainage tube body, which can play a role in dredging the drainage tube body, thereby reducing the probability of blockage in the drainage tube body, thereby improving the smoothness of chest drainage;

[0021] And after the patient turns sideways, on the one hand, due to the discomfort caused by lying on the back for a long time, the patient needs to turn sideways briefly to move the body, and then return to the supine position after lying on the side for a few seconds; on the other hand, after the patient changes from the supine position to the lateral position, when it is found that the drainage tube body is pressed by the body, the position of the drainage tube body can be adjusted to avoid the drainage tube body being pressed for a long time when the patient keeps lying on the side. In these two aspects, the risk of the drainage tube body being pressed can be reduced in the process of the patient changing from the supine position to the lateral position. At the same time, due to the provision of the deflation switch, while the inflated second airbag plays a supporting role, the gas in the second airbag can be gradually released from the deflation switch, thereby reducing the expansion degree of the second airbag, so as to ensure the smoothness of subsequent drainage;

[0022] 2. Further, by providing a support member, the support member is a hollow sponge or rubber structure. On the one hand, the support member can support the first airbag and make the first airbag inflated. On the other hand, its hollow structure can accommodate gas, so that when the first airbag is squeezed, the gas in the first airbag flows to the second airbag and the deflation switch through the first one-way valve. Moreover, by providing a second one-way valve, when the first airbag is not squeezed, the deflated support member can restore its deformation, and the gas in the external environment can flow to the first airbag through the second one-way valve, thereby replenishing gas to the first airbag, so that when the patient turns sideways later, the second airbag can be inflated again, so as to protect the drainage tube body again.

[0023] 3. Furthermore, by providing a fixing patch, the fixing patch can be adhered to the patient's body, thereby facilitating the fixation of the first airbag, thereby improving the convenience of fixing the first airbag, and at the same time, when the first airbag is fixed on the patient's body, the drainage tube body can be limited, further reducing the risk of the drainage tube body falling off the patient's body.
