Detailed Description

The technical scheme of the invention is described in detail in the following with reference to the accompanying drawings.

Embodiment 1, the present invention provides a directional blasting balloon, referring to fig. 1, including a balloon body 11 and a catheter 12 connected to the balloon, wherein the balloon body includes a blasting portion 13 and a non-blasting portion 14 integrally connected to the blasting portion, and the blasting portion is located at a front end of the balloon body; the blasting part and the non-blasting part are connected in a sealing mode, the thickness of the blasting part is smaller than that of the non-blasting part, and in brief, the thickness of the front end of the balloon body is smaller than that of the rear end of the balloon body. As a variant, the non-explosive part and the explosive part may also be connected integrally by a sealing connection instead of being connected integrally.

To facilitate controlled inflation of the balloon, referring to fig. 2, the end of the catheter remote from the balloon body is fitted with an air inlet valve 15, the fitting of which is well known to those skilled in the art and will not be described herein in any greater detail.

In order to facilitate the control of inflating the balloon and the introduction of the balloon body, referring to fig. 3, an air tube 16 and a guide wire 17 are installed in the catheter and are communicated with the balloon body, the air tube and the guide wire are exposed out of one end of the catheter far away from the balloon body, and the installation of the air tube and the guide wire is well known in the technical scheme of the field and is not described herein again. For convenience in use, a liquid inlet pipe 18 is installed in the catheter, an outlet of the liquid inlet pipe is located at one end, close to the rear end of the balloon body, of the catheter, liquid medicine and the like can be conveyed through the liquid inlet pipe, so that the balloon can be conveniently used, the trachea, the guide wire and the liquid inlet pipe can be installed in the conventional installation mode, for example, the trachea, the guide wire and the liquid inlet pipe are separated by arranging an interlayer in the middle of the catheter, and therefore the balloon can be inflated only by arranging small holes communicated with the trachea at the position where the catheter is connected with the balloon body or the position inside the balloon body.

Example 2, in addition to example 1, in the present application, the applicant has made a design in which, referring to fig. 4, a recessed portion 19 is provided at the tip end of the balloon body, and the thickness of the recessed portion is smaller than that of the non-explosive portion to constitute an explosive portion; a plurality of first elastic braces 20 are circumferentially arranged at the front end of the concave part, the first elastic braces are connected with the guide pipe, and a space is reserved between every two adjacent first elastic braces; the rear end of depressed part is provided with second elasticity brace 21, the second elasticity brace with the pipe is connected, has the interval between the adjacent second elasticity brace, first elasticity brace, second elasticity brace and the preferred same material that uses of sacculus body just the thickness of first elasticity brace and second elasticity brace is greater than the thickness of depressed part, the thickness of first elasticity brace and second elasticity brace is generally selected and is the same with the thickness of non-blasting portion. The first elastic brace and the second elastic brace are preferably circumferentially and uniformly arranged. When the structure is not used, the balloon body is shriveled, when the structure is used, the balloon body is inflated, the balloon body is expanded, the concave part is formed under the action of the first elastic brace and the second elastic brace, and the thickness of the concave part is smaller than that of the non-blasting part, so that the concave part is firstly damaged during blasting, gas in the balloon flows forwards along the interval between the first elastic braces, the first elastic brace and the second elastic brace contract to a certain extent to prevent the influence of overlarge airflow on blood vessels, and the interval between the first elastic brace and the second elastic brace is reduced due to the contraction of the first elastic brace, so that the overlarge airflow is further prevented. Typically, the first resilient stay is substantially perpendicular to the axis of the balloon body when deployed, i.e., the first resilient stay is substantially perpendicular to the catheter after inflation of the balloon.

It should be noted that the front end and the rear end described in the present application are defined according to the front and rear directions of the balloon when in use, and it can be clearly understood from fig. 1 to 4, the connection form of the balloon and the catheter is not limited to the form in fig. 1, for example, the catheter inside the balloon body in the figure may be removed to directly feed air at the rear end of the balloon body, which are well known to those skilled in the art and will not be described herein again.
