Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a balloon dilatation catheter for the cardiology field comprises a catheter main body 1, a balloon 5 is arranged inside the catheter main body 1, an expansion ring 3 is connected to the outside of the balloon 5, a catheter 2 is arranged inside the balloon 5, an air hole 4 is arranged outside the catheter 2, one end of the catheter main body 1 is connected with an inflation head 8, one end of the inflation head 8 is connected with a pressure pump connector 6, and an anchor ear 7 is arranged outside the pressure pump connector 6.

This device is through pipe 2 that sets up, gas pocket 4, sacculus 5, expansion ring 3, when pipe 2 aerifys, sacculus 5 expansion, the area grow that sacculus 5 that has expansion ring 3 through setting up makes sacculus 5 expansion under the same atmospheric pressure, make the abundant expansion of blood vessel that is blockked up, reduced and leaded to the risk that blood can not normally flow inadequately because of sacculus 5 expansion, fill head 8 through setting up, force pump connector 6, staple bolt 7, loosen or lock through staple bolt 7, make fill head 8 and force pump connector 6 loosen or lock, aerify for pipe 2, application staple bolt 7 simple structure, the staff's of being convenient for operation is simple

Please refer to fig. 3, the inflation head 8 is located on the inner wall of the pressure pump connector 6, and the inflation head 8 is detachably connected with the pressure pump connector 6 through the hoop 7, so that the hoop 7 is simple in structure and convenient for inflation.

Please refer to fig. 1, the end of the catheter 2 away from the inflation head 8 is provided with a tip 10, the catheter 2 is provided with a non-transmission mark ring 9 on the outer side of the balloon 5, and the position of the balloon 5 is marked by finding the non-transmission mark ring 9 under an X-ray machine.

Please refer to fig. 1, the balloon 5 is made of Pebax material, the catheter 2 is made of rubber material, and the Pebax material has good resilience and elastic recovery, so as to facilitate the expansion and contraction of the balloon 5.

Please refer to fig. 1, the outer side of the catheter 2 is provided with a hydrophilic coating, and the hydrophilic coating is made of a hydrocoat material.

Please refer to fig. 1, the number of the expansion rings 3 is four, and the four groups of expansion rings 3 are uniformly arranged about the longitudinal central axis of the balloon 5, so that the expansion rings 3 can effectively enlarge the expansion area of the balloon.

The working principle is as follows: when the balloon dilatation catheter is needed, firstly, the catheter 2 in the catheter main body 1 is placed in the lesion position of a patient, after the catheter 2 enters the human body and reaches the periphery of the lesion position, the position of the saccule 5 is marked by finding the non-projection marking ring 10 under an X-ray machine, the catheter 2 is inflated, so that the gas is discharged into the saccule 5 through the air hole 4, the saccule 5 is inflated and expanded, because the balloon 5 is provided with the expansion ring 3, the expansion area of the balloon 5 under the same air pressure is enlarged, so that the blocked blood vessel is fully expanded, the risk that the blood can not flow normally due to the insufficient expansion of the saccule 5 is reduced, on inflating head 8 and being connected with pressure pump connector 6 and aerifing, lock through staple bolt 7, only need unscrew or elasticity staple bolt 7 aerify and part, application staple bolt 7 simple structure, the staff's operation of being convenient for.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
