Abstract
The invention discloses an angiographic catheter for bronchial arteries, and the angiographic catheter comprises a catheter. An end part of the catheter is a spiral pigtail-shaped end pipe, and the catheter is perpendicular to an end face of the end pipe. The end pipe is provided with a side hole, and the projection of the catheter in the vertical direction is coincided with the circular projection of the end face of the catheter. The end pipe is connected with the catheter to form a body, or the end pipe is detachably disposed on the catheter. The end pipe is provided with the side hole, and the catheter is put at an opening part of a bronchia in an aorta cavity, so as to achieve radiography. The side hole is close to the opening of the bronchia as much as possible. A contrast medium flows out from the side hole, and enters into the bronchia for arteriography. The contrast medium flows downwards along the wall of an aorta. The catheter enables bronchial arteries to be found easily, enables minute vessels to be displayed easily, and is good in arteriography effect.
Description
Technical field
The invention belongs to area of medical devices, particularly relate to a kind of BAG pipe.
Background technology
Be not specifically designed to the conduit of BAG at present, the general Cobra of employing manages or head hunter catheter, finds arteriae bronchiales, waste time and energy, often can not find arteriae bronchiales, conventional pigtail catheter is when radiography, need very a large amount of contrast agent, use inconvenience.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of BAG pipe, and when being intended to solve BAG, common conduit is not easy to find arteriae bronchiales, the problem that the contrast agent dosage of use is large.
The present invention is achieved in that a kind of BAG pipe comprises conduit, and the end of described conduit is the end pipe of the pigtail shape of spiral, and described conduit is vertical with the end face of end pipe, and described end pipe is provided with side opening.
Further, described conduit overlaps with the circular projection of end end surfaces in the projection of vertical direction.
Further, described end pipe and conduit are connected as a single entity or hold and manage dismountable being arranged on conduit.
The end pipe of BAG pipe of the present invention is provided with side opening, the above radiography of aorta lumen entobronchus opening inserted by BAG pipe, side opening can as much as possible near arteriae bronchiales opening, contrast agent flows out from side opening and enters BAG, contrast agent is along aorta wall toward current downflow, easy discovery arteriae bronchiales, easily show thin vessels, and contrasting effects is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the BAG pipe that the embodiment of the present invention provides;
Fig. 2 is the use schematic diagram of the BAG pipe that the embodiment of the present invention provides;
In figure: 1, conduit; 2, end pipe; 3, aorta; 4, side opening.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, this present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this present invention, be not intended to limit the present invention.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
Fig. 1 shows the structure of BAG pipe of the present invention, as shown in the figure, the present invention realizes like this, a kind of BAG pipe comprises conduit 1, the end of described conduit 1 is the end pipe 2 of the pigtail shape of spiral, described conduit 1 is vertical with the end face of end pipe 2, and described end pipe 2 is provided with side opening 4.
Further, described conduit 1 overlaps with the circular projection of end pipe 2 end face in the projection of vertical direction.
Further, described end pipe 2 and conduit 1 are connected as a single entity or hold that pipe 2 is dismountable to be arranged on conduit 1.
As shown in Figure 2, during use, the above radiography of aorta 3 intracavity bronchus opening inserted by BAG pipe of the present invention, side opening 4 can as much as possible near arteriae bronchiales opening, contrast agent flows out from side opening and enters BAG, and contrast agent, along aorta wall toward current downflow, easily finds arteriae bronchiales, easy display thin vessels, contrasting effects is good.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
Claims (3)
