The utility model discloses simple structure, easy and simple to handle with foetus target blood vessel firm in connection, and the injection pressure and the groundwater increment of controllable filler, avoid or to have reduced the outer hourglass of filler extravagant, make the foetus sample to fill the effect better.
Description
Technical field
This utility model belongs to anatomy technical field, is related to a kind of vascular perfusion making fetus blood vessel cast moulds
Pipe.
Background technology
At present, in terms of the trend of research human vas and distribution, human vas cast moulds are that preferable blood vessel manifests
Method.In cast moulds manufacturing process, it needs special device for casting to be filled with agent to the Target organ blood vessel of human body
Perfusion.Because fetus blood vessels caliber is comparatively fine many compared with adult's blood vessels caliber, and tube wall is thin, poor flexibility, therefore making fetus
Blood vessel casting specimen is relatively grown up much more difficult.Normal adult's blood vessel casting intrusion pipe cannot be with the bore phase of fetus target blood
Join, thus filler can not be caused to leak outside in a large number waste with fetus target blood close communication, lead to Foetal organ to irrigate not
Good.
Utility model content
The purpose of this utility model is to provide a kind of fetus blood vessel cast moulds intrusion pipe, can be with different gestational age fetus
External caliber is seamlessly connected, easy and simple to handle, and the injection pressure of controlled filler and groundwater increment, it is to avoid or decrease filler
Leakage wastes, and makes the perfusion effect of fetus specimen more preferably.
In order to realize reaching above-mentioned purpose, a kind of fetus blood vessel cast moulds intrusion pipe that this utility model provides, adopt with
Lower technical scheme：Including joint（1）, rubber tube（2）And pipette tips（3）It is hollow pipeline structure, joint（1）With rubber tube（2）
Junction be provided with joint groove（5）, in joint groove after connection（5）Tied a knot with suture and fix in place；Rubber tube（2）Wrap rifle
Head（3）Bulge loop（6）Suture is used in bulge loop after tube wall（6）At tube wall, knotting is fixed, and for making it internal overall for one, is divided with glue
Not in rubber tube（2）Bond firmly at the suture of two ends, pipette tips groove（4）It is immediately to be made in slotting fetus target blood,
Fetus target blood fully wrapped around pipette tips groove is made in catheterization procedure（4）Use suture afterwards in pipette tips groove（4）Place's knotting is fixed, and makes
Fetus target blood and intrusion pipe become an entirety.
For make further intrusion pipe closely coupled reach seamless, using 502 glue described intrusion pipe rubber tube two
Carry out at the suture of end instiling bonding firmly.
The beneficial effects of the utility model are：This utility model structure is simple, joint portion between the body of described intrusion pipe
Position is very firm.When intrusion pipe is connected with fetus target blood, can be according to different gestational age fetus target blood pipe diameter size, that is,
When make intrusion pipe pipette tips taper end groove location（Mouth of pipe footpath is close with fetus target blood caliber herein）And remove below groove
Tip portion, is inserted into fetus target blood inwall, is tied a knot with suture in groove and fixes.Which increase intrusion pipe groove position
Put taper end portion caliber, resistance during minimizing perfusion is it is ensured that the branches at different levels of fetus target blood obtain effectively fully irrigating.Simultaneously
Control injection pressure and the groundwater increment of filler according to the rubber tube degrees of expansion of intrusion pipe, it is to avoid lead because injection pressure is excessive
The rupture of fetal parts branch vessel is caused to cause the leakage of filler to waste, thus reaching optimal perfusion effect purpose.

Specific embodiment
In order to further appreciate that feature of the present utility model, technological means and the specific purposes being reached, function, parsing
Advantage of the present utility model and innovation and application, mat has and below in conjunction with drawings and Examples, the technical solution of the utility model is obtained
Further elucidated above.
As shown in Figure of description, this utility model includes joint 1, rubber tube 2 and pipette tips 3 three part tube body, and body is equal
For hollow pipeline structure.One end mouth of pipe of described joint 1 is closely connected with disposable syringe cone head hole, and other end tube wall is arranged
There is joint groove 5；Described pipette tips 3 have bulge loop 6 to be tapered along the other end direction for one end；Rubber tube 2 one end tube wall is complete
Carry out knotting after wrapping connector groove 5 to fix with suture, rubber tube 2 other end is fully wrapped around in the same manner at described joint groove 5
Carry out knotting after pipette tips bulge loop 6 to fix with suture at bulge loop 6 tube wall.Finally, beaten in rubber tube terminal suture using 502 glue
Carry out at knot instiling bonding firmly, become intrusion pipe.The material of described joint 1 is 6mm for outer diameter tube, and internal diameter is 4mm's
PE trachea or PU trachea；The material of described joint 2 is 8mm for outer diameter tube, and internal diameter is the medical latex tube of 6mm；Described pipette tips 3
Material be capacity 0.5ml medical pipet pipette tips.
This utility model, in slotting fetus target blood, according to fetus target blood pipe diameter size, uses common hacksaw immediately
Piece makes pipette tips groove 4 by hand, then is modified with knife blade, makes pipette tips groove 4 smooth surface, it is to avoid cusped edge acute angle is brought
Fetus target blood damage.Need after fully wrapped around for fetus target blood pipette tips groove 4 in catheterization procedure, with suture in groove
At 4, knotting is fixed, and makes fetus target blood and this utility model become an entirety.
When with disposable syringe perfusion filler, filler first passes through this utility model and enters fetus target blood
Interior, because fetus target blood feature is from the coarse to fine, perfusion resistance is to be gradually increased.It may appear that rubber in bolus infusion processes
Pipe 2 increases and obvious swelling because of perfusion resistance.When rubber tube 2 expands to a certain degree, syringe should be stopped immediately and inject
And clamp rubber tube at joint groove 5 with mosquito forcepss, using the effect of caoutchouc elasticity retraction, the filler residing in rubber tube 2 is continued
Continue and be pushed into blood vessel distal.
In sum, this utility model structure is simple, easy and simple to handle, is connected firmly with fetus target blood.According to difference
Gestational age fetus target blood pipe diameter size, adjusting grooves 4 position.Degrees of expansion according to rubber tube 2 in perfusion, controls syringe
Inject pressure and groundwater increment.So both can be avoided because blindness inject pressure excessive lead to fetal parts branch vessel rupture make
Become filler leakage to waste, abundant perfusion minute blood vessel purpose can be reached again.
The above enforcement only have expressed some embodiments of the present utility model, and its description is more concrete and detailed, but
Therefore the restriction to this utility model scope can not be interpreted as.It should be pointed out that the ordinary skill people for this area
For member, without departing from the concept of the premise utility, some deformation can also be made and improve, these belong to this practicality
New protection domain.Therefore, protection domain of the present utility model should be defined by claims.
