[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] See also Figure 1-2 The utility model provides a cardiovascular surgical drainage device, comprising a drainage tube 1, the drainage tube 1 is connected to a joint 3 through a pressurizing structure 2, and a straightening structure 4 is sleeved on the outer wall of the drainage tube 1.

[0013] Drainage is performed through the drainage tube 1, which is connected to the pipeline buried in the patient's body through the connector 3. The pressurizing structure 2 can continuously apply pressurization to prevent the connection from being blocked by blood clots, tissue fragments, etc., which would affect the drainage effect. The straightening structure 4 can also ensure that the pipeline is unobstructed, avoiding blockage of the drainage tube by knots, etc., thereby ensuring the smoothness of the drainage work.

[0014] The pressurizing structure 2 includes a support tube 21, which is fixedly assembled on the side end of the drainage tube 1, and a joint 3 is installed through the inner wall of the support tube 21, and the joint 3 is connected to the drainage tube 1. The outer wall of the joint 3 is sleeved with a slide tube 22, and the inner end of the slide tube 22 is convex, and the convex position of the slide tube 22 squeezes the joint 3 to deform. The outer wall of the joint 3 is sleeved with a spring 24, one end of the spring 24 is connected to the inner wall of the support tube 21, and the other end of the spring 24 is connected to the slide tube 22. The outer wall of the slide tube 22 is sleeved with a push plate 23.

[0015] When blood clots, tissue fragments, etc. block the connection between the connector 3 and the drainage tube 1, the push plate 23 is pushed, and the slide cylinder 22 is driven to move on the inner wall of the support cylinder 21, squeezing the spring 24 to deform it, releasing the push plate 23, and the slide cylinder 22 returns to its original position again. This is repeated, and the connector 3 is continuously pressurized through the raised position to flush away the blood clots, tissue fragments, etc.

[0016] The straightening structure 4 comprises a straightening cylinder 42 which is sleeved on the outer wall of the drainage tube 1 , a cone cylinder 43 is fixedly connected to the side of the straightening cylinder 42 away from the pressurizing structure 2 , and a push block 41 is fixedly mounted on the outer wall of the straightening cylinder 42 .

[0017] When the drainage tube 1 is knotted and entangled, the push block 41 can be pushed to drive the straightening cylinder 42 to move. Due to the setting of the cone cylinder 43, it is convenient to push away the knotted and bent position. At this time, the straightening cylinder 42 can be placed here to avoid knotting and bending again.

[0018] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
