One end of the connector body 1 is provided with a straight hole 11, the other end of the connector body 1 is provided with a main channel hole 12 and a side channel hole 13, the main channel hole 12 is communicated with the straight hole 11, the connector body 1 is provided with a staggered hole 14, the staggered hole 14 is communicated with the side channel hole 13 and the straight hole 11 respectively. In actual use, a pipeline can be inserted into the straight hole 11 and the main channel hole 12 respectively; because the main channel hole 12 is communicated with the straight hole 11, the pipelines inserted into the two can also be communicated, so as to realize the circulation of fluid; in addition, a pipeline can also be inserted into the side channel hole 13, the pipeline inserted into the side channel hole 13 will be communicated with the staggered hole 14, and because the staggered hole 14 is communicated with the straight hole 11, the pipeline inserted into the side channel hole 13 is also communicated with the straight hole 11, so as to realize the coexistence and sharing of double channels.

[0025] The medical cylindrical multi-channel adapter adopts an integrally injection-molded adapter body 1, avoiding the trouble of assembling components and simplifying the mechanical structure, so that the structure of the adapter is simpler, the fluid circulation in the adapter can be improved, and the processing and assembly are facilitated. On the other hand, by providing the misaligned hole 14 in the adapter body 1, the main channel hole 12 and the side channel hole 13 can coexist and share, and the integrally formed structure can improve the sealing performance when connecting the pipeline, thereby reducing the occurrence of liquid leakage and improving the use experience.

[0026] In this embodiment, the main channel hole 12 and the central axis of the straight-through hole 11 coincide with each other; so that the main channel hole 12 and the straight-through hole 11 form a straight-through hole; if a hollow pipeline electrode is connected thereto, the straight-through hole can become a dual-function channel for fluid and electrode, improving the application scenarios of the adapter and improving the versatility.

[0027] The inner side wall of the straight-through hole 11 is provided with a first limiting step surface 15, which is used for limiting the pipeline inserted into the straight-through hole 11, so that the pipeline inserted into the straight-through hole 11 can be fixed and limited, improving the stability of the structure.

[0028] The main channel hole 12 is provided with an annular limiting boss 16, which is used for limiting the pipeline inserted into the main channel hole 12, so that the pipeline inserted into the main channel hole 12 can be fixed and limited, improving the stability of the structure. At the same time, the side away from the main channel hole 12 of the annular limiting boss 16 can also be used for limiting the pipeline inserted into the straight-through hole 11; in actual use, two layers of sleeves can be inserted into the straight-through hole 11, so that the first limiting step surface 15 can be used for limiting the outer sleeve, and the annular limiting boss 16 can be used for limiting the inner sleeve, so that the inner sleeve can communicate with the pipeline inserted into the main channel hole 12.

[0029] The second limiting step surface 17 is arranged in the side channel hole 13, and the second limiting step surface 17 is used for limiting the pipeline inserted into the side channel hole 13, so that the pipeline inserted into the side channel hole 13 can be fixed and limited, improving the stability of the structure.

[0030] Embodiment 2:

[0031] As shown in Figure 3 , the structure of this embodiment is similar to that of embodiment 1, and the difference is that in this embodiment, the number of side channel holes 13 is two, the number of misaligned holes 14 in the adapter body 1 is also two, and the positions of the side channel holes 13 and the misaligned holes 14 are one-to-one corresponding.

[0032] Two side channel holes 13 are symmetrically arranged around the main channel hole 12; the end faces of the two side channel holes 13 are flush with the end face of the main channel hole 12; thus, the end of the adapter away from the through hole 11 forms an array-like connector structure centered on the main channel hole 12. This structural arrangement allows the adapter to be used in three-channel pipeline connections, meeting the needs of specific application scenarios.

[0033] In other embodiments, the number of side channel holes 13 and misaligned holes 14 may also exceed two, as long as they are set in a one-to-one correspondence and all side channel holes 13 are arrayed around the main channel hole 12.

[0034] Example 3:

[0035] like Figure 4 As shown, the overall structure of this embodiment is similar to that of Embodiment 2, except that in this embodiment, the end faces of the two side channel holes 13 are not flush with the end face of the main channel hole 12. Instead, the end faces of the two side channel holes 13 and the main channel hole 12 are arranged in a stepped structure. By setting the multiple side channel holes 13 and the main channel hole 12 in a stepped structure, it is easier to connect external pipes to the adapter, which facilitates assembly, improves assembly efficiency, and thus meets the usage requirements in some specific scenarios.

[0036] In other embodiments, the number of side channel holes 13 may also exceed two. It is only necessary to ensure that the end faces of all side channel holes 13 are staggered with the end faces of the main channel holes 12, so as to facilitate the insertion of pipelines and the storage and organization of pipeline structures.

[0037] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model.
