Arteries and veins, small cardiac vein etc., the blood of each cardiac veins flows into coronary sinus vein, and this coronary sinus vein suction catheter is not
Only have stomidium 132 at conduit head section far-end, the sidewall of conduit head section 1 have side opening 131 the most simultaneously,
When conduit head section 1 is positioned in coronary sinus vein, stomidium 132 is towards great cardiac vein position, and side opening 131 is then
Arrange along each collateral remittance mouth, by coordinating between stomidium 132 with side opening 131, can draw crown simultaneously
Many places venous blood in venous sinus, improves uniformity and the efficiency of suction blood；On the other hand, multiple circulations
Hole 13 can be prevented effectively from the blocking of conduit head section, when indivedual openings block, can be carried out by other openings
Blood aspirates, and keeps the suction of conduit head section to smoothly complete.
In the present embodiment, the area sum of described stomidium 132 and described side opening 131 is near more than conduit head section
The area of section of end inner chamber, mainly in view of the opening resistance to blood flow, is conducive to improving blood and draws
Speed, meanwhile, the area sum of described stomidium 132 and described side opening 131 less than 1.5 times of conduit head section near
The area of section of end inner chamber, it is to avoid suction blood excessive velocities sucks atrium dextrum blood.
The caliber of described conduit head section 1 tapers into conduit head section distal direction along conduit head section near-end,
This is close with the form of the coronary sinus vein of human body, is conducive to more penetrating deeply into crown by conduit head section 1
In venous sinus, gathering the blood sample of coronary sinus vein depths, avoid being mixed into the blood of atrium dextrum simultaneously, raising is adopted
The accuracy of collection blood sample.
Concrete, the caliber of described conduit head section near-end is 6～9F, and the caliber of described conduit head section far-end is 3～6
F, the abbreviation that caliber unit is F, i.e. French employed in the utility model, it is possible to be abbreviated as FR or
Fr, 3F=1mm.
As shown in figures 1 and 3, described coronary sinus vein suction catheter also includes external interface 3, described body
External tapping 3 is connected with extension 2, and described external interface 3 connects extracorporeal device, and described extracorporeal device can be
Pressure extension tube, syringe, vacuum tube, the device such as vavuum pump, it is used for forming coronary sinus vein suction catheter
Interior subnormal ambient, to aspirate the blood in coronary sinus vein by coronary sinus vein suction catheter.
The utility model does not limit the particular type of external interface 3, and those skilled in the art can enter according to actual needs
Row select, other external interfaces that can realize linkage function also should be included in protection domain of the present utility model it
In.
Described conduit head section 1 and extension 2 are structure as a whole, and conduit head section 1 and extension 2 are tool
There is the soft material of certain elasticity of flexure, when conduit head section 1 enters coronary sinus vein blood vessel, described conduit
Head section 1 can be advanced along blood vessel.And there is backing material (such as steel wire) in tube wall middle level, prevent from folding and subsiding.
Described coronary sinus vein suction catheter has the characteristic of conduit, and surface and inner chamber are smooth, can inhale by anti-Hemostatic Oral Liquid
Echo aggegation.
When disclosed in employing the utility model, a kind of coronary sinus vein suction catheter carries out coronary sinus vein suction,
Its operating process is:
Step one: selecting subclavian vein or right internal jugular vein is point of puncture, partly sterilised wears with puncture needle
Thorn left subclavian vein or right internal jugular vein；
Step 2: send into seal wire, fixing seal wire after seeing puncture needle blood back in nook closing member, extract puncture needle, then
