Description
Technical field
The utility model relates to medical instruments fields, more particularly to a kind of right suprarenal vein blood sampling interposing catheter.
Background technique
Point side Adrenal venous sampling technology is clinically used for the classification diagnosis of primary aldosteronism, because of right side
The characteristics of adrenal veins anatomical position and structure, without the reasons such as interposing catheter of suitably taking a blood sample, so that right side adrenal gland is quiet
Arteries and veins blood sampling success rate is lower, is the difficult point of the technology.
Right side adrenal veins are open from inferior caval vein, and the angle with inferior caval vein is in downward acute angle, and trunk is short and small, blood
It manages tiny.The blood sampling of the renal arteriography pipe progress right side adrenal veins of the multi-purpose 5F of method at present through upper limb path, but because
Short and small and blood vessel is tiny for trunk, conduit head end is easy top and arrives vascular wall, causes blood that can not produce, or blood sampling is very slow, causes
Plugging.Therefore interventional procedure doctor beats side opening in conduit head end with syringe needle, this side opening edge is inevitably crude, is easy
The relatively thin vein of tube wall is damaged, vein interlayer, local hematoma are caused.In addition, with the side opening work easy to form that syringe needle is beaten
Valve, vein pressure is low, and the negative pressure of blood sampling makes flap valve plugging, causes blood sampling difficult instead.Therefore, we are quiet according to right side adrenal gland
The anatomical features of arteries and veins, the right side Adrenal venous sampling interposing catheter of design specialized, improve right side Adrenal venous sampling at
Power shortens operation time, avoids the generation of complication.
The disclosure of background above technology contents is only used for the design and technical solution that auxiliary understands the utility model, not
The prior art for necessarily belonging to present patent application shows above content in the applying date of present patent application in no tangible proof
In the case where having disclosed, above-mentioned background technique should not be taken to the novelty and creativeness of evaluation the application.
Utility model content
The utility model aim is to propose a kind of dedicated right suprarenal vein blood sampling interposing catheter, so that harvesting blood
It is simple and easy, speed is fast, will not plugging, taken a blood sample low success rate of skill with solving above-mentioned right suprarenal vein of the existing technology
Art problem.
For this purpose, the utility model proposes a kind of right suprarenal vein blood sampling interposing catheter, specific technical solution is as follows.
A kind of right suprarenal vein blood sampling interposing catheter, including head end, bending section, tube body, tail end, it is characterised in that: institute
It states and opens side opening at the head end edge 1-2cm of conduit.
The right suprarenal vein blood sampling interposing catheter, the angle of the bending section of the conduit is 45 ° or 135 °.
The right suprarenal vein blood sampling interposing catheter, the bending section of the conduit is at a distance from head end edge
3.5-4.5cm。
The right suprarenal vein blood sampling interposing catheter, the length of the tube body of the conduit is 80-150cm.
Preferably, the utility model can also have following technical characteristic:
The guiding-tube bend degree suitable for upper limb blood flow paths is 135 °, and the conduit suitable for lower limb vascular path is curved
Curvature is 45 °.
The catheter tube length is 80-150cm, the patient suitable for different heights.
The beneficial effect that the utility model is compared with the prior art includes:
(1) the utility model opens side opening at venous blood collection interposing catheter head end edge 1-3cm, can make venous blood collection
Operation is simple, and success rate is high.
(2) the utility model opens side opening in catheter flange, it is possible to prevente effectively from blood sampling caused by conductor housing is adherent is difficult, leads
A bending section is designed at tube head end margin 3.5-4.5cm, meets the anatomical features of adrenal veins and the operation of different doctors
Habit.
(3) the utility model uses the conduit of 135 ° and 45 ° two kinds of differently curved angles, is suitable for upper limb with lower limb vascular
The differently curved degree in path.
(4) the utility model uses tube length for the conduit of 80-150cm, and the patient that can be adapted for different heights makes
Use demand.
(5) it is that conduit head end top is bent to vascular wall, conduit leading portion that the utility model, which solves currently used catheter manipulation,
Difficulty of taking a blood sample is spent caused by side opening formation flap valve that is improper, being beaten with syringe needle, and relatively thin with the side opening damage tube wall that syringe needle is beaten
Vein, lead to vein interlayer, the problems such as local hematoma.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment 1；
Fig. 2 is the structural schematic diagram of the utility model embodiment 2；
Fig. 3 is the Local map of the utility model embodiment 1.
In figure: 1- head end, 2- side opening, the bending section 3-, 4- tube body.
Specific embodiment
With reference to embodiment and compares attached drawing the utility model is described in further detail.It should be emphasized that
It is that following the description is only exemplary, rather than in order to limit the scope of the utility model and its application.
Referring to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical appended drawing reference indicates
Identical component, unless stated otherwise.
