Detailed ways

The technical solutions of the present utility model are further described in detail through the following examples in conjunction with the accompanying drawings, but the present utility model is not limited only to the following examples. the

What Fig. 1 shows is the structure diagram of a kind of preferred coronary angiography balloon catheter 10 of the present utility model, comprises tubular body 12, and tubular body 12 comprises far-end and proximal end, and the far-end of described tubular body is connected with fixed An elbow end 14, a handle 13 is connected to the proximal end of the tubular body 12. the

2 is a cross-sectional view of a coronary sinus angiography balloon catheter 10 according to a preferred embodiment of the present invention. The tubular body 12 includes a central cavity 23 whose hardness gradually increases from the distal end to the proximal end. The distal end of the pipe body 12 is a fixed elbow end 14, and the fixed elbow end includes a head end pipe 41; the far end of the head end pipe 41 is provided with a ring electrode 42, which is located on the head end pipe. The inner surface of the distal end is extruded and fixed by a section of short tube 43. The ring electrode 42 is used for developing. The distal end of the head-end tube 41 is coated with glue for fixing the ring electrode 42 and making the distal end of the head-end tube 41 relatively smooth. the

A balloon 15 is arranged between the tube body 12 and the head end tube 41, and the end of the balloon 15 is fixed on a section of the inner tube 22, which can be fixed by glue bonding or other suitable fixing methods; There is a certain gap between the rest of the balloon 15 and the inner tube 22. The distal end of the inner tube 22 is fixed to the proximal end of the head end tube 41, and the proximal end of the inner tube 22 is fixed to the distal end of the tube body 12, which can be fixed by glue bonding or other suitable methods. fixed method. A gas channel 24 is provided on the inner tube 22, which may be in any suitable form, such as a small hole or the like. The fixing between the distal end of the balloon 15 and the head-end tube 41 and between the proximal end of the balloon 15 and the tube body 12 may also be fixed by glue bonding or other suitable fixing methods. the

A tube 24 extends inside the central chamber 23 , wherein the distal end of the tube 24 extends to the distal end of the inner tube 22 , and its proximal end extends into the handle 13 . the

The handle 13 comprises a handle body 31 comprising at least one chamber. According to a preferred embodiment of the present invention, the handle body includes two chambers, and the pipeline 24 extends in one of the chambers. Gas enters the central chamber 23 of the tube body 12 from another chamber of the handle body, and enters the balloon 15 through the gas channel 24 of the inner tube 22 . A connecting pipe 32 is provided between the handle body 31 and the pipe body 21 . the

According to a preferred embodiment of the present invention, when the coronary angiography balloon catheter is in use, the catheter is first sent to the coronary sinus, and then the gas enters the tube body through another chamber of the handle body In the central chamber 23 of 12, the gas channel 24 through the inner tube 22 enters the balloon 15, so that the balloon is inflated to temporarily block the coronary sinus. At this time, the contrast agent is sent into the head end tube 41 through the pipeline 24, and developed by the ring electrode 42, so that the depth of the catheter entry can be observed. the

The implementation of the present utility model is not limited to the above-mentioned examples. Without departing from the spirit and scope of the present utility model, those skilled in the art can make various changes and improvements to the present utility model in terms of form and details. , and these are considered to fall into the protection scope of the present utility model. the
