[0029] The embodiment of the application provides a fixing structure, which inserts the fixing column 02 into the middle of the shunt structure 01 to play a role in fixing the oxygenator. In the specific use process, the bottom of the fixing column 02 can also be fixed on a specific structure, so that the fixing of the oxygenator is more stable.

[0030] The different structures of several shunt structures in the embodiment of the application are introduced as follows.

[0031] The shunt structure 01 is mainly communicated with the blood inlet of the oxygenator to shunt and process the blood flowing into the oxygenator. In the embodiment of the application, the shunt structure 01 comprises a first shunt part 01-1 and a second shunt part arranged at intervals, and the first shunt part 01-1 and the second shunt part are connected through a connecting element 01-3. After the blood flows through the first shunt part 01-1, the blood is diffused along the periphery of the second shunt part. The technical scheme of the application is described in detail in the following specific embodiments.

[0032] Example 1

[0033] As shown in Figure 3 and 4 The embodiment of the application provides a shunt structure 01, which comprises a first shunt part 01-1 and a second shunt part arranged at intervals, and the first shunt part 01-1 and the second shunt part are connected through a connecting element 01-3.

[0034] The first shunt part 01-1 is provided with an opening away from the end of the second shunt part, the end of the second shunt part close to the first shunt part 01-1 is in a blocking state, and the first shunt part 01-1 and the second shunt part are hollow structures.

[0035] The first shunt structure 01 is arranged close to the connecting piece 01-3, and the second shunt structure 01 is arranged away from the connecting piece 01-3.

[0036] The connecting piece 01-3 comprises a plurality of connecting units, one end of the plurality of connecting units is distributed around the connecting part at intervals, and the other end of the plurality of connecting units is connected to the first shunt column away from the end of the second shunt column; that is, the other end of the plurality of connecting units in the application is integrated together and connected to the shunt part, and one end of the plurality of connecting units is distributed around the connecting part at intervals; in the embodiment of the application, since the connecting part is a central cylindrical structure, one end of the plurality of connecting units is connected to the side wall of the connecting part at intervals, and the connecting piece 01-3 unit is a strip-shaped structure.

[0037] In the embodiment of the application, the first shunt unit 01-2-1 is a hollow conical structure, the cross-sectional diameter of the first shunt unit 01-2-1 gradually increases from close to the connecting piece 01-3 to the first shunt unit 01-2-1, and the second shunt unit 01-2-2 is a hollow columnar structure; that is, the plurality of connecting units are connected to the tip of the conical structure, and the first shunt unit 01-2-1 and the second shunt unit 01-2-2 have no any protruding parts on the peripheral surface.

[0038] Further, the first shunt unit 01-2-1 and the second shunt unit 01-2-2 are both hollow structures, and the first shunt unit 01-2-1 and the second shunt unit 01-2-2 are provided with a plurality of third muscle structures arranged at intervals on the inner wall of the end away from the connecting piece 01-3.

[0039] Further, the first shunt part 01-1 and the second shunt part are coaxial, which can facilitate the assembly of the entire product.

[0040] In the embodiment of the application, during the use of the oxygenator, blood flows into the first shunt part 01-1 from the blood inlet, then the blood flows from the first shunt part 01-1 to the periphery of the second shunt part for shunt treatment, and after the shunt treatment, the blood flows to other components of the oxygenator such as the heat exchange part or the oxygenation part for treatment.

[0041] By connecting the first shunt part 01-1 and the second shunt part in the shunt structure 01 through the connecting piece 01-3, and not connecting the first shunt part 01-1 and the second shunt part together, it is beneficial to the release of bubbles in the blood.

[0042] Example 2

[0043] As shown in Figure 5 and 6 The difference between the embodiment 2 and the embodiment 1 is that: a plurality of the connecting units are distributed at intervals on the periphery of the first shunt unit 01-2-1, and the end surface of the connecting piece 01-3 arranged on the first shunt unit 01-2-1 is higher than the surface of the first shunt unit 01-2-1, that is, the connecting piece 01-3 and any protruding piece are not arranged on the outer surface of the second shunt unit 01-2-2 in the embodiment.

[0044] The same parts of the embodiment 2 as the embodiment 1 are not described here.

[0045] In the embodiment of the application, during the use of the oxygenator, the blood flows from the blood inlet into the first shunt part 01-1 first, and then the blood flows from the first shunt part 01-1 to the periphery of the second shunt part for shunt treatment. In the specific shunt treatment process, the plurality of connecting units arranged on the periphery of the first shunt unit 01-2-1 play a role in forming a blood shunt channel, so that the blood shunt is more sufficient. After the shunt treatment, the blood flows to other components of the oxygenator, such as the heat exchange part or the oxygenation part, for treatment.
