The mark line extends to the edge of big pod apertures from body afterbody.
Length of the length of the tube core more than body.
The utility model obtains following beneficial effect.
The utility model effectively solves existing extracorporal circulatory system arterial perfusion cannula and easily causes intubation position telecentricity
Hold the problem of limb ischemia anoxic.The utility model of so design has broken traditional femoral arteriography can only supply side blood flow
Situation, can simultaneously carry out the two-way blood supply of artery, prevent femoral arteriography position distal ischemia anoxic even amputation it is concurrent
Disease, substantially increases patient with operation or extracorporeal life supports the security of patient.The utility model be adapted to femoral artery, axillary artery,
The extracorporal circulatory system arterial perfusion cannula at the positions such as truncus brachiocephalicus, is adapted to the external of Heart and great blood vessel polytype open surgery and follows
Ring, is particularly suitable for the femoral artery infusion of long-time extracorporeal life support.The utility model design is simple, easy to use, for once
Property is used, and the need for fully meeting clinic, is had broad application prospects.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the utility model.
As shown in Figure 1-2, a kind of extracorporal circulatory system two-way filling arterial cannulation, including body 1, the body 1 includes tool
Body head 3, body front portion 8, body middle part 9 and the tail end for having cecum are combined with the body afterbody 10 of joint 2；The body head
The small pod apertures 6 and big pod apertures 7 for being opened on the both sides symmetric position of body head 3 respectively are formed with the outer wall in portion 3；Described
Snap ring 4 is provided with tube wall between body head 3 and body front portion 8；It is provided with the body middle part 9 and is embedded in pipe
Helical spring 11 in body tube wall；The tube core 12 that front end is butted on body head cecum, the pipe are additionally provided with the body 1
The outer wall of core 12 is close to the medial surface at body middle part 9；Be formed with the outer wall of the body 1 parallel to body axis and
Just to the mark line 5 at the center of big pod apertures 7.
The body anterior 8 and body middle part 9 for etc. gauge structure；Body afterbody 10 is the expanding knot of tail end diameter increase
Structure.
The ovalize of the snap ring 4, is arranged at cecum 10mm, oval long axis ray and the mark of the snap ring
Line 5 is perpendicular.
The small pod apertures 6 and big pod apertures 7 are arranged at cecum 1mm.
The mark line 5 extends to the edge of big pod apertures 7 from body afterbody 10.
Length of the length of the tube core 12 more than body 1.
Body head 3 of the present utility model slightly expands, and pipe thickness is 1mm；A diameter of 4-5mm of small pod apertures 6, leads greatly
A diameter of 8-10mm of discharge orifice 7；Snap ring 4 is ellipse, and major axis is higher by tube wall 5mm per side, and short axle is higher by tube wall 1mm per side；Pipe
Body front portion 8 15mm-20mm long, a diameter of 8-11mm；9 100mm long of body middle part；The 100mm long of body afterbody 10；Tube core 12 is than pipe
The 30-50mm long of body 1；Body head 3, snap ring 4, body anterior 8 and joint 2 are hard transparent medical plastic material, inflexibility；
Body middle part 9 and body afterbody 10 are flexible transparent medical grade plastic material.The utility model can be according to arterial vascular diameter
It is designed to different size.
Helical spring 11 in the utility model plays a part of support, reinforces tube wall, because 9 materials of body middle part are soft
It is soft, angulation when body embedded set helical spring 11 can prevent chamber collapse, prevent arterial cannulation to be bent steering；Tube core 12 sets
Arterial cannulation is held when meter is beneficial to surgical procedures, the purpose that tube core 12 is adjacent to 9 medial surfaces of body middle part is to prevent intubation
When leak blood.
Working condition of the present utility model is as follows：The femoral artery of intubation of carrying out ahead of schedule is dissected, exposed, is stitched on femoral artery outer wall
Good purse wire（It is not shown）It is standby, temporarily pressed from both sides in femoral artery proximal part artery clamp and closed, then puncture femoral artery simultaneously with scalpel
Suitably expand, insertion the utility model body head 3, and large and small pod apertures direction is adjusted rapidly according to mark line 5, make to lead greatly
Discharge orifice 7 tightens up purse wire towards femoral artery proximal part, small pod apertures 6 towards femoral artery distal end after adjustment direction, ligature and solid
Due on snap ring 4, preventing intubation from deviating from femoral artery, then can connection extracorporeal circulation pipeline（It is not shown）Or extracorporeal life is supported
Pipeline（It is not shown）, start the blood perfusion that extracorporal circulatory system or extracorporeal life are supported.
Because arterial cannulation body head 3 has large and small pod apertures, and it is respectively facing the proximal part and telecentricity of femoral artery
End, so whether proximal part or distal end have the hemoperfusion of abundance, it is to avoid limb ischemia below intubation position,
A problem that anoxic or even necrosis, amputation, occurs.
