Abstract

The utility model provides a taper integrated balloon dilator, and belongs to the technical field of medical appliances. The tapered integrated balloon dilator includes a tube portion and a balloon portion. The tail end of the catheter is provided with a joint part, and the inside of the catheter is provided with an air guide cavity layer. The columnar hollow balloon section is communicated with the front end of the conical hollow balloon section, a plurality of ventilation connecting pipes are obliquely arranged inside the columnar hollow balloon section, the bottom ends of the ventilation connecting pipes are communicated with the air guide cavity layer in the catheter, and the top ends of the ventilation connecting pipes are communicated with the columnar hollow balloon section. The guide tube drives the columnar hollow balloon segment and the conical hollow balloon segment to penetrate into the blood vessel, and the conical hollow balloon segment has smaller resistance when penetrating into the blood vessel and can more easily penetrate through a narrow position in the blood vessel. The pressurized gas enters the cylindrical hollow saccule section to bulge and expand the blood vessel, and the ventilation connecting pipe can be used for supporting the cylindrical hollow saccule section to stably expand the blood vessel after being inflated, so that the support and expansion effects are better.

Description

Taper integrated type balloon dilator Technical Field The utility model relates to the technical field of medical instruments, in particular to a taper integrated balloon dilator. Background The balloon dilator is a medical appliance and is mainly used for treating certain heart diseases, vascular stenosis, urinary tract obstruction and other problems. An unobstructed medical balloon is disclosed in publication No. CN219375828U, and comprises a balloon body, a catheter and a three-way connector, wherein one end of the catheter is connected with the balloon body, the other end of the catheter is connected with the three-way connector, a guide wire connecting cavity and a pressure pump connecting cavity are arranged on the three-way connector, the connecting part of the catheter and the balloon body is positioned at the side edge of the balloon body, and the inner cavity of the balloon body is communicated with the inner cavity of the catheter body. When the medical balloon is used, the whole balloon is of a columnar structure, when the balloon is introduced into a blood vessel, the front end section of the balloon is relatively large, the resistance is large when the balloon is introduced into a narrow region of the blood vessel, and the condition that the introduction is difficult exists. Disclosure of utility model In order to make up for the defects, the utility model provides a taper integrated balloon dilator, which aims to improve the problem that the balloon in the related art is of a columnar structure as a whole, when the balloon is introduced into a blood vessel, the section of the front end of the balloon is relatively large, and the resistance is large when the balloon is introduced into a narrow region of the blood vessel, so that the introduction is difficult.
