Description
Technical field
The utility model is related to extracorporeal lifes to support experimental technique field, and in particular to a boar jugular vein is intubated.
Background technology
Extracorporeal life supports that technology is the extension and development of Cardiopulmonary Bypass.Central vessel need to be carried out with extracorporal circulatory system
(aorta ascendens, atrium dextrum or superior and inferior vena cave) intubation is different, and extracorporeal life supports technology to generally require progress peripheral blood vessel and insert
Pipe.In clinical position, patient's vein usually selects femoral venous catheter to carry out extracorporeal life support.Carrying out extracorporeal life support
When zoopery, if experimental animal is selected as pig, since pig femoral vein is thinner, it can not be intubated, therefore need to select quiet in neck
Arteries and veins is intubated.Current there is no dedicated pig jugular vein to be intubated on the market, and the femoral venous catheter for being often used Clinical practice replaces, by
This brings following a series of problems：
The first, femoral venous catheter is longer, typically larger than 50cm, makes troubles to intubation, while unnecessary increase
Pipeline priming volume.
The second, femoral venous catheter front end side hole number is more and long, usually has side opening part caliber to be about 15-20cm.By
It is shorter in the path of jugular vein to atrium dextrum, intubation occur often side opening not yet completely into blood vessel the problem of, influence external
Life supports the progress of experiment；Or due to for by whole side openings merging blood vessel cause to be intubated it is too deep in addition cause atrium dextrum or under
The severe complications such as vena cave rupture equally affect the progress that extracorporeal life supports experiment.
Utility model content
It supports to test unmatched problem to solve existing femoral venous catheter for pig extracorporeal life, the utility model provides
One boar jugular vein be intubated, the venous cannula be suitble to pig jugular vein to atrium dextrum length, avoid side opening not completely into
The problem of blood vessel, occurs, while can be to avoid the generation caused by pig cervical incision relatively depth the problems such as difficult intubation.
Technical solutions of the utility model are as follows：
One boar jugular vein is intubated, which includes being intubated ontology and cannula core, and the one of the cannula core
End is blunt tip, the other end connecting insertion plug of cannula core；After the cannula core stretches into intubation ontology, cannula core
Blunt tip can be stretched out by the front end of intubation ontology；The intubation plug can detachably connect with the end for being intubated ontology
It connects；Side opening is provided on the intubation ontology, the front end distance of side opening distance intubation ontology is 8-12cm；Before the intubation ontology
End is intubated the end of ontology for connecting extracorporeal circulation set tube road for being inserted into jugular vein.
The included wire loop of leading portion of the intubation ontology, can avoid pipeline and gives a discount；The length of included wire loop is 25-
35cmm。
Individual event flap valve is equipped in the intubation plug, blood will not when capable of ensureing to be intubated ontology connecting insertion plug
It is sprayed from plug.
The cannula core can move in intubation plug.
The end of the intubation ontology is equipped with female Luer, is exhausted by female Luer, ontology will be intubated after exhaust
Piping connection is supported with extracorporeal life.
The cannula core material is aluminium, so that cannula core is bent and/or is shaped on demand, to drive intubation
Ontology realizes bending and/or sizing, ensures that intubation can carry out intubation with certain curvature.
It is as follows that the utility model pig jugular vein is intubated application method：
Intubation ontology is assembled with cannula core and according to the appropriately curved intubation ontology of the depth of jugular vein notch and pipe
Core then cuts jugular vein in favor of being easily intubated, and intubation ontology and tube core are inserted into jugular vein, completed in neck
Venous cannula operates, and exits cannula core, connects extracorporeal circulation pipeline.As arterial cannulation is completed at this time, you can start external
Life is supported.
The utility model has the beneficial effects that：
The utility model and Clinical practice femoral venous catheter main difference is that intubation and intubation leading portion side opening length are shorter,
Pig jugular vein can be suitble to be intubated needs, avoid the occurrence of the problems such as side opening is exposed to outside blood vessel.Further, since cannula core
It can be bent, shape, therefore intubation can be bent to appropriate angle, be come compared with bathozone due to pig jugular vein notch with reduction
Intubation is inconvenient.

Specific implementation mode
The utility model is further illustrated below in conjunction with the accompanying drawings.
The utility model is intubated for pig jugular vein, supports experiment, structure as shown in Figs. 1-3 for pig extracorporeal life.
The venous cannula includes intubation ontology 4 and cannula core 1, and one end of the cannula core 1 is blunt tip 11, separately
One end is with intubation plug 2；The cannula core 1 can move in intubation plug 2.Cannula core 1 stretches into intubation ontology 4
Afterwards, the blunt tip 11 of cannula core 1 is stretched out by the front end 41 of intubation ontology；The intubation plug 2 that cannula core 1 connects and intubation
The end 42 of ontology can be detachably connected；Be uniformly distributed multiple side openings 43 on the leading portion of the intubation ontology 4, side opening 43 with insert
41 maximum distance of front end of tube body is preferably 10cm (this segment length that side opening is distributed with is preferably 10cm)；The position of side opening can
Cause atrial lesions or side opening exposed to avoid since intubation is long.
For being inserted into jugular vein, the end for being intubated ontology is equipped with female Luer 3, passes through for the front end 41 of the intubation ontology
Female Luer 3 can be exhausted, and intubation ontology is supported piping connection with extracorporeal life after exhaust.
The included wire loop of leading portion of the intubation ontology 4, can avoid pipeline and gives a discount；This segment length of included wire loop is
25-35cmm, preferably 30cm.
Individual event flap valve is equipped in the intubation plug 2, blood when capable of ensureing to be intubated 4 connecting insertion plug 2 of ontology
It will not be sprayed from plug.
1 material of the cannula core is aluminium, so that cannula core 1 is bent and/or is shaped on demand, is inserted to drive
Tube body 4 realizes bending and/or sizing, ensures that intubation can carry out intubation with certain curvature.
According to jugular vein intubation is assembled shown in Fig. 3, i.e., the cannula core 1 with plug is inserted into intubation ontology 4.It is inserted
Guan Shi cuts jugular vein intubation, and the intubation combined is inserted into jugular vein and enters atrium dextrum, ensure whole side openings 43 into
Enter atrium dextrum and superior vena cava；Cannula core 1 is then pulled out, so that cannula core 1 is retreated at intubation plug 2, unscrews female Luer, blood
Liquid is from heart outflow full of intubation ontology, and then traling female Luer, extracts cannula core and intubation plug, intubation ontology connection
Extracorporeal life supports pipeline, you can carries out circulatory assit.
Particular embodiments described above has carried out into one the purpose of this utility model, technical solution and advantageous effect
The detailed description of step is not limited to it should be understood that the foregoing is merely specific embodiment of the utility model
The utility model, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should all
