The technical scheme adopted by the utility model for solving the technical problems is as follows: two-chamber PICC towards pipe Y type connects, including cavity spheroid, joint one, joint two and joint three, a joint fixed connection be in the cavity spheroid lower extreme, connect two fixed connection be in the upper right end of cavity spheroid, connect three fixed connection be in the upper left end of cavity spheroid, a joint end is equipped with the syringe interface, joint two with three ends all are equipped with spiral infusion interface, the inside rotation of cavity spheroid is connected with the shutoff ball, the inside Y word runner that is equipped with of shutoff ball, cavity spheroid front end rotates and is connected with the pivot, the pivot rear end run through to the cavity spheroid inside and with the shutoff ball is fixed.

Preferably, the first joint is communicated with the hollow sphere, the second joint is communicated with the hollow sphere, and the third joint is communicated with the hollow sphere.

Preferably, three ends of the Y-shaped flow passage are all communicated with the blocking ball.

Preferably, the upper right side of the front end of the rotating shaft is fixedly connected with a pointing rod.

Preferably, a rotating ring is arranged outside the front end of the rotating shaft, and the tail end of the pointing rod is fixedly connected with the rotating ring.

Compared with the prior art, the utility model has the following beneficial effects: this kind of two-chamber PICC towards pipe Y type connects, connects two and connects three ends to adopt spiral infusion interface, can be perfect and the infusion joint combine, prevent the weeping, rotate the pivot moreover, make directional pole get directional department liquid and not circulate, can take back the pump in single chamber and look over and have or not blood returned to the seal pipe only need seal a pipeline just can, thereby the comparatively convenience of seal pipe.

In the figure: 1-hollow sphere, 2-joint I, 3-joint II, 4-joint III, 5-spiral transfusion joint, 6-injector joint, 7-rotating shaft, 8-pointing rod, 9-rotating ring, 10-blocking ball and 11-Y-shaped flow passage.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

As shown in fig. 1-2, the double-cavity PICC flush tube Y-shaped joint comprises a hollow sphere 1, a joint one 2, a joint two 3 and a joint three 4, wherein the joint one 2 is fixedly connected to the lower end of the hollow sphere 1, the joint two 3 is fixedly connected to the upper right end of the hollow sphere 1, the joint three 4 is fixedly connected to the upper left end of the hollow sphere 1, the end of the joint one 2 is provided with a syringe connector 6, the ends of the joint two 3 and the joint three 4 are both provided with a spiral infusion connector 5, the hollow sphere 1 is rotatably connected with a plugging ball 10, a Y-shaped flow passage 11 is arranged inside the plugging ball 10, the front end of the hollow sphere 1 is rotatably connected with a rotating shaft 7, the rear end of the rotating shaft 7 penetrates into the hollow sphere 1 and is fixed with the plugging ball 10, the joint one 2 is communicated with the hollow sphere 1, the joint two 3 is communicated with the hollow sphere 1, the third connector 4 is communicated with the hollow sphere 1, three ends of the Y-shaped flow channel 11 are all communicated with the blocking ball 10, the upper right side of the front end of the rotating shaft 7 is fixedly connected with a pointing rod 8, a rotating ring 9 is arranged outside the front end of the rotating shaft 7, the tail end of the pointing rod 8 is fixedly connected with the rotating ring 9, when the ball valve is used, the rotating ring 9 can drive the rotating shaft 7 to rotate through the pointing rod 8 by rotating the rotating ring 9, so that the rotating shaft 7 drives the blocking ball 10 to rotate inside the hollow sphere 1, and when the pointing position of the pointing rod 8 is not provided with an opening of the Y-shaped flow channel 11, the third connector 4 is not communicated with the Y-shaped flow channel 11 when the ball valve rotates leftwards to the third connector 4 of the pointing rod 8, and when the pointing rod 8 rotates rightwards to the second connector 3 of the pointing rod 8, the second connector 3 is not communicated with the Y-shaped flow channel 11;
