Can be through the foley's tube of bloodTechnical field
This utility model relates to a kind of medical apparatus and instruments, specifically is a kind ofly can be mainly used in the blood vessel balloon dilatation through the foley's tube of blood.
Background technology
Reasons such as arteriosclerosis cause stricture of artery to be blocked, if narrow position is tiny, can adopt the aortic sac dilatation to treat, and the intravascular epidural catheter placement of the capsule that is about to dribble is expanded narrow tremulous pulse, and need not to carry out large-scale cardiac operation.This conduit generally has two hollow channels, and its head end has a sacculus, and the end of conduit is provided with Y shape interface.Two interfaces of Y shape communicate with sacculus and the end that passes the conduit of sacculus through two passages in the conduit respectively.Two passages of conduit are respectively applied for through seal wire with to the sacculus pressurization, utilize the stenosis of expansible balloon expandable tremulous pulse, reach the purpose of treatment.In the above-mentioned therapeutic process,, blocked the blood supply of remote organization fully, caused remote organization's ischemia, had potential safety hazard, possibly influence therapeutic effect and cause complication when after the inflation time at blood vessel dilating.
Summary of the invention
The purpose of this utility model provide a kind of can be through the foley's tube of blood, to reduce operation risk, improve success rate of operation, reduce complication and take place.
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; CompriseY shape interface 1,conduit 2 andsacculus 3; Two tops ofY shape interface 1 arepressurization interface 11 andseal wire interface 12, and the bottom ofY shape interface 1 is connected with the head end ofconduit 2, and the end ofconduit 2 passes sacculus 3 (sacculus 3 is enclosed in the periphery ofconduit 2 ends).Be provided withpressurization passageway 21 andsilk guide passage 22 in thisconduit 2; Thepressurization interface 11 of Y shape interface communicates with sacculus 3 (being provided with theblow vent 23 that communicates withpressurization passageway 21 on the tube wall of theconduit 2 in sacculus 3) through thepressurization passageway 21 in theconduit 2, and theseal wire interface 12 ofY shape interface 1 communicates with thesilk guide passage 22 of conduit.It is characterized in that: be provided with theblood channel 4 that connects with its two ends at saidsacculus 3 two ends, thisblood channel 4 comprises following several kinds of structures.
Referring to Fig. 2-Fig. 4, theconduit 2 of this embodiment is located at the axle center ofsacculus 3, a plurality ofblood channels 4 along circle distribution around conduit 2.Be divided intopressurization passageway 21 andsilk guide passage 22 in theconduit 2,pressurization passageway 21 is atsacculus 3 inner sealings, and communicates withsacculus 3 inside through the blow vent on the tube wall 23.Andsilk guide passage 22 continues up to end.
Referring to Fig. 5-Fig. 6, theconduit 2 of this embodiment is located at the side (tube wall ofconduit 2 one sides can interconnect with a side of sacculus 3) in thesacculus 3, establishes ablood channel 4 that internal diameter is bigger on the next door ofconduit 2.
Referring to Fig. 7-Fig. 8, theconduit 2 of this embodiment also is located at the axle center ofsacculus 3, and twoblood channels 4 are located at the relative both sides ofconduit 2, and both can interconnect at an adjacentside.Pressurization passageway 21 in theconduit 2 andsilk guide passage 22 can the concentric settings, are located at can all be provided withblow vent 23 like this inpressurization passageway 21 both sides and communicate withsacculus 3 inside.
Referring to Fig. 9; This embodiment is provided with theblood conducting orifice 24 that communicates withsilk guide passage 22 on the tube wall away from theconduit 2 of catheter tip (left end of Fig. 9 sacculus 3) that is arranged insacculus 3 ofconduit 2, the terminalsilk guide passage 22 of thisblood conducting orifice 24 toconduit 2 is as blood channel 4 (seal wire and blood common-use tunnel).
Referring to Figure 10, this embodiment is provided withblood channel 4 in the inboard that is positioned atsacculus 3 ofconduit 2, and there is side opening 24 (silk guide passage 22 is separated withblood channel 24 mutually) at two ends
Outer surface at saidsacculus 3 is coated with anesthesia or/and prevent restenosis medicaments (conventional medicine) coating.
This utility model afterconduit 2 imports arterial vascular stenosis, injects liquid with thepressurization interface 11 of syringe throughY shape interface 1 in use tosacculus 3 in,sacculus 3 expands stenosis is supportted greatly; And blood flows throughblood channel 4 swimmingly.In importing the process ofconduit 2, in blood vessel, inject contrast agent with theseal wire interface 12 of syringe throughY shape interface 1 as required, so that can observe the lead-in path ofconduit 2 from video equipment.
