The inner of described bypass I, bypass II all connects at upper cylinder inner core center and main road, and bypass I, bypass II symmetry are positioned at main road both sides.
The angle of described bypass I, bypass II and main road is 60 degree.
On described rotary switch, have and main road, bypass I and bypass II four handgrips one to one.
The advantage the utlity model has and effect:
1, this utility model is continued to use the custom that original Medical tee joint uses, and newly increases an interface in the situation that its volume is substantially constant, can reach original two Medical tee joints and connect the effect using, more convenient to operate, flexible, safety.
2, this utility model has been saved medical resource, has alleviated sufferer financial burden, has also reduced medical-risk simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the A-A cutaway view of Fig. 1,
Fig. 3 is structure top view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1,2,3, a kind of embodiment of the present utility model is described.
A kind of medical administration cross valve, comprises cylindrical housings 1, is provided with cylinder inner core 2 and lower cylinder inner core 3, and seals between upper cylinder inner core 2 and lower cylinder inner core 3 outer walls and cylindrical housings 1 inwall in described cylindrical housings 1; The interior level of described upper cylinder inner core 2 is shaped with trident passage, and described trident passage is made up of with the bypass I 5, the bypass II 6 that are positioned at main road both sides and be communicated with main road a main road 4 that runs through upper cylinder inner core 2 centers; One side correspondence of described cylindrical housings 1 has main road interface 7, bypass I interface 8, bypass II interface 9, and in the time of main road interface 7 connection corresponding with main road 4, bypass I interface 8, bypass II interface 9 respectively with the corresponding connection in outer end of bypass I 5, bypass II 6; In described upper cylinder inner core 2, be shaped with Vertical Channel I 10, the horizontal channel 12 that is shaped with Vertical Channel II 11 in lower cylinder inner core 3 and is communicated with Vertical Channel II lower end, and Vertical Channel I 10 and Vertical Channel II 11 are positioned on same centrage, and the upper end of Vertical Channel I 10 is communicated with main road 4, the corresponding connection in upper end of lower end and Vertical Channel II 11; The opposite side of described cylindrical housings 1 has joint 13, and the inner corresponding connection in outer end with horizontal channel 12 of the interface channel 14 having in joint 13; On the upper surface of described upper cylinder inner core 2, be fixed with rotary switch 15, lower cylinder inner core 3 is fixed on the bottom surface of cylindrical housings 1 by lower surface.
The inner of described bypass I 5, bypass II 6 all connects in upper cylinder inner core 2 centers and main road 4, and bypass I 5, bypass II 6 symmetries are positioned at main road 4 both sides.Described bypass I 5, bypass II 6 are 60 degree with the angle of main road 4.On described rotary switch 15, have and main road 4, bypass I 5 and bypass II 6 four handgrips 16 one to one.
