As shown in Fig. 1 and Fig. 2, the present invention is made up of catheter body 1 etc., and one end of the catheter body 1 is provided with support meanss, institute
Stating support meanss includes the sleeve 11 being made with the injection moulding integrated molding of catheter body 1, catch 12 is provided with the sleeve 11, described
Catch 12 is provided with opening stage clip 13 towards the side of the openend of catheter body 1, and one end of the opening stage clip 13 abuts with catch 12；
Wireway 14 is equipped with the catch 12, support air bag 15 is provided with the wireway 14, the support air bag 15 is worn
It is located in stage clip 13, the support air bag 15 extrudes opening stage clip 13 after inflating, while reclaiming catheter body 1, catheter body 1 is with set
Cylinder 11 is moved together, and after sleeve 11 completely disengages from opening stage clip 13, opening stage clip 13 opens in the presence of a tensile force, and supports
Firmly the inwall of correspondence position blood vessel, is further continued for being inflated to support air bag 15, support air bag 15 is persistently compressed opening stage clip 13, directly
Buckle-like is formed between opening stage clip 13 and blood vessel, you can deflate and withdraw catheter body 1.
Partition 2 is provided with the catheter body 1, gap is left between the partition 2 and catch 12, the width in the gap is
The inner chamber of catheter body 1 is divided into the first cavity 21 and the second cavity 22 by 5~10mm, preferably 8mm, the partition 2, and described first is empty
The side of the correspondence catheter body 1 of chamber 21 is provided with five blood back holes 16, and the wireway 14 is located in the first cavity 21.
Blocking device is equipped with second cavity 22, the blocking device includes guide pipe 31, the guide pipe 31
Inserting end be provided with bending segment 311, the diameter of the bending segment 311 is less than the through-hole diameter on guide pipe 1, the bending segment
311 length is 0.5~1.5mm, preferably 1mm；Gas tube 32 is equipped with the guide pipe 31, is set on the gas tube
The side for having blocking air bag 33, second cavity 22 correspondence catheter body 1 is provided with eight through holes, and the guide pipe 31 stretches out correspondence position
The through hole put, and guide gas tube 32 to stretch into the blood vessel of correspondence position, inflate to reach to enter target blood to air bag 33 is blocked
Row is blocked, the purpose of anti-hemostasis backflow.
Application method of the invention is as follows：
Embodiment 1：
As shown in figure 1, when such as resistance blood target blood is smaller, then should not directly use the clamp that stops blooding using resistance vim and vigour capsule 15
Handle target blood；The opening stage clip 13 that reselection is adapted with support target vessel diameter, extrudes opening stage clip 13
After be put into sleeve 11, the inserting end of opening stage clip 13 is connected on catch 12, wireway 14 is fed through catch 12, and connects
There is support air bag 15, meanwhile, the support air bag 15 allowed on catheter body 1 is located in the stage clip 13 of opening, and blood is stretched into along catheter body 1
Pipe, until sleeve 11 reaches support target vessel position, now, is inflated to support air bag 15, and the lateral surface of support air bag 15 is supported
Catch opening stage clip 13 medial surface, because the lateral surface of support air bag 15 is thin-skinned compared with the outside of sleeve 11, opening stage clip 13 with
Can be formed between support air bag 15 and be close to shape, now, outwards back pull catheter body 1, and band moving sleeve 11 to move together, in branch
Support air bag 15 be close to effect under, opening stage clip 13 will not be moved with the movement of sleeve 11, when opening stage clip 13 is fully removed
After outside sleeve 11, in the presence of a tensile force, opening stage clip 13 opens, and is supported with the correspondence position of support target blood vessel
Connect, then, be moved to prevent opening stage clip 13 from being obtained pressure influence by Ink vessel transfusing, continue to be filled to support air bag 15
Gas, allows the lateral surface of support air bag 15 to abut the medial surface of the stage clip 13 that is open again, and now, be open stage clip 13 and blood vessel
Between can be formed be close to close shape, keep a period of time abutting after, deflated to support spring 15, support air bag 15 is in opening stage clip
In 13 after one section of translation, reinflated abutment openings stage clip 13, and kept for a period of time, it is repeated several times, until opening stage clip 13 is whole
Duan Douyu blood vessels are formed is close to shape form, finally, discharges the gas in gas tube 32, withdraws and blocks air bag 33, then discharges
Gas in wireway 14, withdraws catheter body 1 and support air bag 15.
Embodiment 2
As shown in Fig. 2 when such as resistance blood target blood is larger, the damage in order to avoid haemostatic clamp to blood vessel now, is adapted to make
With resistance vim and vigour capsule 15, elder generation extend into the sleeve 11 of catheter body 1 at the position of support target blood vessel, and handle is separated out by partition 2
The second cavity 22 on eight through holes go to resistance blood target blood direction, with reference to auxiliary equipment display, guide pipe 31
The through hole of correspondence position is extend into, and bending segment 311 is directed at corresponding through hole, then, import gas tube 32, the inflation
The inserting end of pipe 32 is also communicated with blocking air bag 33, and gas tube 32 stretches into resistance blood target blood, so under the guide of guide pipe 31
Afterwards, inflated to gas tube 32, block the inflation of air bag 33 (in Fig. 2 shown in dotted line), clogging blood vessel reaches the purpose of resistance blood；
The blood of the second cavity 22 is flowed into from through hole during this period, the first cavity 21 is flowed into by the gap of 8mm between catch 12 and partition 2,
And in by blood back hole 16 again flowing into blood vessel, blood clotting can be prevented and the mobile interference that occurs, finally, according in embodiment 1
Description, start to be supported support target blood vessel operation, and in the completed withdraw catheter body 1 and all parts.
The undescribed part of the invention is identical with the prior art, and therefore not to repeat here.
Embodiments of the present invention are these are only, the scope of the claims of the invention is not thereby limited, it is every using the present invention
The equivalent structure that specification and accompanying drawing content are made, is directly or indirectly used in other related technical fields, similarly at this
Within the scope of patent protection of invention.
