[0032] In addition, the main body 1 is generally installed on the heart-lung machine, so that the first pipeline and the second pipeline on the heart-lung machine can pass through the fixing part on the fixing structure 2, and then be fixed to the main body 1 by the fixing part, so as to avoid the first pipeline and the second pipeline from being entangled with each other and affecting the normal circulation of the liquid in the pipeline. Since the first pipeline and the second pipeline have different outer diameters, the first pipeline and the second pipeline can respectively pass through the fixing parts corresponding to their outer diameters, that is, the first pipeline can pass through the first fixing part 21, and the second pipeline can pass through the second fixing part 22, so as to be fixed to the heart-lung machine by the main body 1.

[0044] The universal cardioplegia fluid card provided in this embodiment is as follows: Figure 1 As shown, the outer diameter of the second pipeline is smaller than or equal to the inner diameter of the second fixing portion 22 , and the outer diameter of the second pipeline is larger than the inner diameter of the first fixing portion 21 .

[0045] The universal cardioplegic fluid clamp of the above structure is configured such that the outer diameter of the second pipeline is smaller than or equal to the inner diameter of the second fixing portion 22 and larger than the inner diameter of the first fixing portion 21 , so that the second pipeline can only pass through the second fixing portion 22 and is then fixed to the main body 1 by the fixing structure 2 .

[0046] The universal cardioplegia fluid card provided in this embodiment is as follows: Figure 1 As shown, the inner diameter of the opening is one-half inch, the inner diameter of the first fixing portion 21 is one-eighth inch, and the inner diameter of the second fixing portion 22 is one-quarter inch.

[0050] The utility model provides a universal cardioplegia fluid clamp, which is provided with a fixing structure 2 on a main body 1, wherein the main body 1 has a mounting cavity with openings at both ends, and the fixing structure 2 is provided in the mounting cavity through one of the openings, and the fixing structure 2 is provided with a first fixing portion 21 and a second fixing portion 22 which are connected to the two openings, and the first fixing portion 21 and the second fixing portion 22 can allow pipelines to pass through and fix the pipelines on the main body 1, and at the same time, the first fixing portion 21 and the second fixing portion 22 are arranged at intervals, and the inner diameters of the first fixing portion 21 and the second fixing portion 22 are different, so that the first fixing portion 21 and the second fixing portion 22 can fix pipelines with different outer diameters, and in addition, the main body 1 is generally installed on a heart-lung machine, so that the first pipeline and the second pipeline on the heart-lung machine can pass through The first pipeline and the second pipeline are fixed to the main body 1 through the fixing part on the fixing structure 2, so as to avoid the first pipeline and the second pipeline from being entangled with each other and affecting the normal circulation of the liquid in the pipeline. Since the outer diameters of the first pipeline and the second pipeline are different, the first pipeline and the second pipeline can pass through the fixing parts corresponding to their outer diameters respectively, that is, the first pipeline can pass through the first fixing part 21, and the second pipeline can pass through the second fixing part 22, so as to be fixed to the heart-lung machine by the main body 1. Therefore, by making the main body 1 have the first fixing part 21 and the second fixing part 22, the main body 1 can be adapted to pipelines of different models, thereby avoiding the problem of replacing the universal cardioplegia fluid clamp when fixing pipelines of different models, thereby reducing the workload of medical staff and improving the safety of the universal cardioplegia fluid clamp.
