Abstract
The utility model relates to a puncture guide device used for cardiovascular intervention therapy, which belongs to the technical field of medical instruments. The puncture guide device is characterized in that a puncture needle is sleeved on a syringe needle seat at the front end of a syringe, an axial tube communicated with the syringe needle seat is arranged inside the syringe, four mutually symmetrical circular through holes are formed on the axial tube adjacent to the inner wall at the front end of the syringe, a conical plastic thin film barrel capable of automatically sealing at the front end is fixedly connected on the inner wall of the axial tube above the circular through holes; a plunger sleeved outside the axial tube is respectively in sealing connection with the axial tube and the syringe in a sliding manner, and two handles on the side wall of the plunger respectively penetrate two mutually rectangular axial through holes on the syringe wall of the syringe to be exposed outside the syringe; and a sealing plug is arranged inside the rear end of the axial tube and fixedly connected with a syringe cover sleeved at the rear end of the syringe. The utility model has the advantages that after the puncture needle is inserted into the blood vessel, the guide wire can be smoothly inserted in the blood vessel along the axial tube and the puncture needle, so as to avoid the displacement of the puncture needle and to prevent the blood from leaking and the working surface from being polluted.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of cardiovascular interventional therapy puncture guider.
Background technology
When carrying out the cardiovascular interventional therapy, directly thrust blood vessel or thrust blood vessel at present, then syringe is unloaded from puncture needle, again seal wire is sent into blood vessel by piercing needle with ordinary syringe with puncture needle.The shortcoming of above-mentioned piercing method is: flow out a lot of blood from the needle holder mouth after puncture needle inserts blood vessel, wasted valuable blood on the one hand, also can pollute work surface on the other hand, and in wearing the process of seal wire, also cause the puncture needle displacement easily, even cause puncture failure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can prevent the cardiovascular interventional therapy puncture guider in puncture hourglass blood and puncture needle displacement for seal wire leads when cardiovascular punctures.
The purpose of this utility model is achieved in that this cardiovascular interventional therapy puncture guider is made up of puncture needle, syringe, syringe lid, be with puncture needle on the needle holder of syringe front end, inside is provided with the axle center pipe that is connected with needle holder, axle center pipe near syringe front inner wall place is provided with four symmetrical manholes, is being connected and fixed the self-sealing conical plastics film cylinder of front end energy on the axle center inside pipe wall of manhole top; Slipper seal is connected the piston boit of tube outside, axle center suit with syringe with the axle center pipe respectively, and two handles above the piston boit sidewall pass two symmetrical above syringe barrel rectangle axially extending bores respectively and are exposed at the syringe outside; Pipe inside, rear end, axle center is provided with sealing-plug, and sealing-plug is fixedlyed connected with the syringe lid above being sleeved on back end of syringe.
During use, the puncture needle of syringe front end is inserted blood vessel, two handles above the pulling piston side wall, if there is blood to enter syringe by the manhole above the pipe of axle center, illustrate that syringe needle has inserted blood vessel, pull up the syringe lid then, the seal wire with interventional therapy inserts the axle center pipe after the puncture needle intravasation again.
Advantage of the present utility model: puncture needle can directly insert seal wire the axle center pipe after inserting blood vessel, and along axle center pipe and puncture needle intravasation reposefully, can prevent that puncture needle is shifted, and avoids blood to leak outside and pollutes work surface.

Accompanying drawing is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this cardiovascular interventional therapy puncture guider is made up of puncture needle 1, syringe 2, syringe lid 3, be with puncture needle 1 on the needle holder of syringe 2 front ends, inside is provided with the axle center pipe 4 that is connected with needle holder, axle center pipe 4 near syringe 2 front inner wall places is provided with four symmetrical manholes, and the axle center of manhole top is managed and is being connected and fixed the self-sealing conical plastics film cylinder 5 of front end energy on 4 inwalls; 2 slipper seals are connected the piston boit 6 that 4 outside suits are managed in the axle center with syringe with axle center pipe 4 respectively, and two handles 7 above piston boit 6 sidewalls pass two symmetrical above syringe 2 barrels rectangle axially extending bores 8 respectively and are exposed at syringe 2 outsides; The axle center is managed inside, 4 rear end and is provided with sealing-plug 9, and sealing-plug 9 covers 3 with syringe above being sleeved on syringe 2 rear ends fixedlys connected.
