Abstract
A syringe for cardiovascular intervention comprises a barrel, a plunger, a needle holder at the front tip of the barrel, an axial tube arranged inside the barrel and connected with the needle holder, and an axial hole slidably engaged with the axial tube inside the plunger and inserted into the axial tube. The axial tube shorter in length than the plunger, has a funnel-shaped tail end, and is provided with a radial blood discharge hole on the wall near to the needle holder. A seal stopper with cut seams is arranged on the axial hole at the tail end of the plunger. After the puncture needle is inserted into a blood vessel, the guide catheter is inserted into the seal stopper at the tail end of the plunger via the axial hole without removing the syringe, and is steadily delivered into the vessel along the axial tube and the puncture needle; since the seal stopper can prevent the leakage of blood, the blood flows out of the blood discharge hole on the axial tube under the action of the plunger, helpful to verify and observe that the blood vessel is punctured. During the puncture process, the syringe barrel can be stably held to prevent the displacement of the puncture needle.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically is a kind of when being used for the cardiovascular interventional therapy, seal wire is sent into the injection syringe for cardiovascular intervention of blood vessel.
Background technology
When carrying out the cardiovascular interventional therapy, directly thrust blood vessel or thrust blood vessel with puncture needle, and then syringe is unloaded from puncture needle at present, again seal wire is sent into blood vessel by piercing needle with ordinary syringe.The shortcoming of above-mentioned piercing method is can flow out a lot of blood from the needle holder mouth after pin inserts blood vessel wearing to penetrate, this has wasted valuable blood on the one hand, also can pollute work surface, also can in wearing the process of seal wire, may cause puncture needle displacement injured blood vessel, even cause puncture failure.
Summary of the invention
The purpose of this utility model just provides and a kind ofly prevents at puncture hourglass blood, and for seal wire leads, avoids the injection syringe for cardiovascular intervention of puncture needle displacement.
The technical solution of the utility model is: comprise cylindrical shell, plunger, front end at cylindrical shell has needle holder, the one axle center pipe that links to each other with described needle holder is arranged in described cylindrical shell, the axle center hole that is slidingly matched with described axle center pipe and penetrates this axle center pipe is arranged in described plunger, described axle center pipe is shorter than the length of plunger, the end of axle center pipe is a horn mouth, near on the axle center tube wall of needle holder one end radial blood outlet hole is being arranged.One sealing-plug that has a joint-cutting is arranged on the axle center hole of the end of described plunger.
Described blood outlet hole is three, along axle center tube wall circumference uniform distribution.
Described sealing-plug is made by rubber.
This utility model does not need to unload syringe after puncture needle inserts blood vessel, just the sealing-plug that seal wire is not held from plunger can be inserted axle center hole, and send into blood vessel reposefully along axle center pipe and puncture needle, because the effect of sealing-plug prevents that blood from spilling, and the blood outlet hole on the pipe of axle center can outwards flow out blood under the effect of plunger, so that whether checking and observation puncture needle insert blood vessel.In piercing process, can firmly hold injector cartridge, prevent the displacement of puncture needle.
Description of drawings
Fig. 1 is the axial half sectional view of population structure of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, this utility model comprises cylindrical shell 4, plunger 5, front end at cylindrical shell 4 has needle holder 6, the one axle center pipe 7 that links to each other with described needle holder 6 is arranged in described cylindrical shell 4, the axle center hole 2 that is slidingly matched with described axle center pipe 7 and penetrates this axle center pipe is arranged in described plunger 5, described axle center pipe 7 is shorter than the length of plunger 5, and the end of axle center pipe 7 is a horn mouth 71, on the tube wall near the axle center pipe of an end of needle holder 6 three radial blood outlet holes 8 that are uniformly distributed along the circumference is arranged.One sealing-plug 11 that has a cross joint-cutting is arranged on the axle center hole of the end of described plunger 5.
Described sealing-plug 1 is made by rubber.
When using this utility model to puncture, earlier puncture needle is contained on the needle stand of the present utility model, syringe needle is inserted blood vessel, if have blood to flow into syringe plunger 5 outside moving, illustrate that then syringe needle has inserted blood vessel, again the seal wire of interventional therapy is inserted the axle center hole 2 of plunger by the joint-cutting at sealing-plug 1 center of plunger 5 ends, pass axle center pipe 7 and puncture needle and send into blood vessel.Just can finish the operation of delivery guidewire.
