Three conduits being respectively communicated with three-way connection；The catheter tip is formed with the first inverted sections turned down outward, the threeway
Connector interface end is formed with the second inverted sections of fold inward, and second inverted sections and three-way connection interface inner wall form ring
Shape card slot, first inverted sections are limited in annular slot, are connected between first inverted sections and the second inverted sections
Magnet.
In some embodiments, the magnet includes the first magnet and the second magnet, and first magnet is fixed on the
On one inverted sections, second magnet is fixed on the second inverted sections.
It in some embodiments, further include the O-ring seal in annular slot, the O-ring seal is by first
Inverted sections abut.
In some embodiments, three conduits are respectively two-chamber blood filter arterial duct, transfusion catheter and CRRT machine
Connecting conduit.
Compared with prior art, the utility model has the beneficial effects that by making the first inverted sections be limited in annular snap
In slot, it is connected with magnet between the first inverted sections and the second inverted sections, to increase the connection jail of conduit and three-way connection
Degree, ensure that blood purification and catheters irrigation successfully, can be carried out safely.
Detailed description of the invention
Fig. 1 is a kind of overall structure diagram of CRRT machine conduit connection systems shown in the utility model；
Fig. 2 is the structural schematic diagram of three-way connection and conduit connection shown in Fig. 1.
Specific embodiment
The utility model is described in detail in each embodiment shown in reference to the accompanying drawing, but it should be stated that,
These embodiments are not limitation of the utility model, those of ordinary skill in the art according to these embodiments made by function
Energy, method or equivalent transformation or substitution in structure, belong within the protection scope of the utility model.
A kind of CRRT machine conduit connection systems as illustrated in fig. 1 and 2, including three-way connection 3, three and three-way connection 3
The conduit being respectively communicated with.Three conduits are respectively two-chamber blood filter arterial duct 21, transfusion catheter 4 and CRRT machine connecting conduit
51。
Two-chamber blood filter catheter shown in Fig. 1 include needle tubing 1 and the two-chamber blood being connected to needle tubing 1 filter arterial duct 21 and
Two-chamber blood filters ductus venosus 22.It further include the CRRT machine connecting conduit 51 and CRRT machine connecting conduit 52 being connect with CRRT machine.
CRRT machine connecting conduit 52 is directly connected to two-chamber blood filter ductus venosus 22.Two-chamber blood filters arterial duct 21,4 and of transfusion catheter
CRRT machine connecting conduit 51 is connected to three-way connection 3.In the present embodiment, the number of three-way connection 3 is two, another three
Pass joint 3 connects CRRT machine connecting conduit 51 and transfusion catheter 4.
Needle tubing 1 is pierced into patient's vein, after two-chamber blood filter arterial duct 21 draws blood samples of patients, is handled through CRRT machine
Afterwards, it is transmitted back in patient's vein by two-chamber blood filter ductus venosus 22.It can be functioned as follows by the way that transfusion catheter 4 is arranged, one, punching
Wash two-chamber blood filter arterial duct 21 and CRRT machine connecting conduit 51, two, quick dilatation, three, resisting blood coagulation.
4 end of transfusion catheter is formed with the first inverted sections 41 turned down outward, the 3 interface end shape of three-way connection
At the second inverted sections 31 for having fold inward, second inverted sections 31 form annular slot (not with 3 interface inner wall of three-way connection
Mark), first inverted sections 41 are limited in annular slot, to increase what transfusion catheter 4 was connect with three-way connection 3
Stability prevents in use, and transfusion catheter 4 is separated with three-way connection 3, grasps blood purification and catheters irrigation etc.
