The technical scheme of this utility model is: a kind of can be through the foley's tube of blood; Comprise Y shape interface, conduit and sacculus; Two tops of Y shape interface are pressurization interface and seal wire interface, and the bottom of Y shape interface is connected with the head end of conduit, and the end of conduit passes sacculus; Be provided with pressurization passageway and silk guide passage in this conduit; The pressurization interface of Y shape interface communicates with sacculus through the pressurization passageway in the conduit; The seal wire interface of Y shape interface communicates with the silk guide passage of conduit, it is characterized in that: be provided with the blood channel that connects with its two ends at said sacculus two ends.

Described conduit is located at the axle center of sacculus, a plurality of described blood channels be located at conduit around.

Described conduit is located at the side in the sacculus, and a described blood channel is located at the next door of conduit.

Described conduit is located at the axle center of sacculus, and two described blood channels are located at the relative both sides of conduit.

On the tube wall away from catheter tip that is positioned at sacculus of said conduit, be provided with the blood conducting orifice that communicates with silk guide passage, the silk guide passage of this blood conducting orifice to catheter tip is as described blood channel.

Outer surface at said sacculus is coated with anesthesia or/and prevent the restenosis medicaments coating.

The utility model has the advantages that: the blood channel that is located at the sacculus two ends can be when the aortic sac dilatation be treated; For blood provides passage, make the blood-based originally can normal circulation, can not block the blood supply of remote organization; Eliminate the potential safety hazard of operation, improved the quality of operation.

The specific embodiment

Referring to Fig. 1～Figure 10; This utility model is a kind of can be through the foley's tube of blood; Comprise Y shape interface 1, conduit 2 and sacculus 3; Two tops of Y shape interface 1 are pressurization interface 11 and seal wire interface 12, and the bottom of Y shape interface 1 is connected with the head end of conduit 2, and the end of conduit 2 passes sacculus 3 (sacculus 3 is enclosed in the periphery of conduit 2 ends).Be provided with pressurization passageway 21 and silk guide passage 22 in this conduit 2; The pressurization interface 11 of Y shape interface communicates with sacculus 3 (being provided with the blow vent 23 that communicates with pressurization passageway 21 on the tube wall of the conduit 2 in sacculus 3) through the pressurization passageway 21 in the conduit 2, and the seal wire interface 12 of Y shape interface 1 communicates with the silk guide passage 22 of conduit.It is characterized in that: be provided with the blood channel 4 that connects with its two ends at said sacculus 3 two ends, this blood channel 4 comprises following several kinds of structures.

Referring to Fig. 2-Fig. 4, the conduit 2 of this embodiment is located at the axle center of sacculus 3, a plurality of blood channels 4 along circle distribution around conduit 2.Be divided into pressurization passageway 21 and silk guide passage 22 in the conduit 2, pressurization passageway 21 is at sacculus 3 inner sealings, and communicates with sacculus 3 inside through the blow vent on the tube wall 23.And silk guide passage 22 continues up to end.

Referring to Fig. 5-Fig. 6, the conduit 2 of this embodiment is located at the side (tube wall of conduit 2 one sides can interconnect with a side of sacculus 3) in the sacculus 3, establishes a blood channel 4 that internal diameter is bigger on the next door of conduit 2.
