Problems solved by technology

[0008] When the conventional double-chamber balloon urinary catheter is filled with water in the airbag, the airbag is filled unevenly, that is, one side of the airbag bulges and the other side does not bulge. It may happen that the airbag at the bleeding point does not bulge and cannot reach the compression bleeding point. purpose, resulting in unsatisfactory hemostatic effect

Abstract

The invention discloses a double-cavity air bag pipe which comprises an air bag pipe body, the air bag pipe body is internally provided with a drainage channel, the front end of the air bag pipe body is provided with a drainage hole communicated with the drainage channel, the tail end of the air bag pipe body is connected with a drainage connector communicated with the drainage channel, the side wall of the front end of the air bag pipe body is provided with an air bag wrapping the drainage channel, the side wall of the air bag pipe body is internally provided with an air inflation channel parallel to the drainage channel, one end of the air inflation channel is communicated with the air bag, the other end of the air inflation channel is connected with an air inflation connector, and the length of the air bag is 0.5-1.5 mm. When the length of the air bag is set to be 0.5-1.5 mm, the air bag can be uniformly filled with air, the phenomenon of eccentric ballooning does not happen easily, the bleeding point can be effectively compressed, and the hemostatic effect is good.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a double-chamber balloon tube. Background technique [0002] Kidney stones are common and frequently-occurring diseases of the urinary system. 40% to 75% of patients with kidney stones have different degrees of low back pain. Kidney stones can not only cause urinary tract damage, urinary tract infection, and urinary system obstruction, but also damage kidney function. Long-term existence will also increase the incidence of urinary system tumors. Surgical operations have always been the main treatment for kidney stones. [0003] Surgical treatment methods for kidney stones mainly include: traditional open lithotripsy, laparoscopic lithotripsy, extracorporeal impact lithotripsy, percutaneous nephrolithotripsy, and retrograde flexible ureteroscopic lithotripsy. [0004] The traditional open stone removal method requires a large incision of about 20 cm in the waist, incision of the muscles in...
