Urethra dilation catheter

Abstract

The invention discloses a urethral expansion catheter, which belongs to the technical field of medical appliances and comprises a straight tube, an elbow connected to the front end of the straight tube, and a handle connected to the rear end of the straight tube. The handle is provided with a urination hole communicating with the straight tube; The front end of the elbow is conical and blunt, with several injection holes on the front end surface, and two catheterization side holes on the side wall of the elbow at the front end; one end of the medicine tube is connected to the injection hole at the front end of the elbow, and the other end extends Out to the outside of the straight pipe and connected with a hose, the hose is provided with a valve and a water pump, and the end of the hose is connected with a liquid storage barrel; the front wall of the straight pipe is provided with an expansion air bag, and the inside of the straight pipe is provided with a A trachea, one end of the trachea is connected with the expansion balloon, and the other end extends out of the straight tube; the rear tube body of the straight tube has a diversion section, and a sampling tube is externally connected to one side of the diversion section. The patient's pain is relieved, and the operation of the medical staff is also convenient, and the catheterization and urethral expansion operations can be completed at the same time.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a urethral expansion catheter. Background technique [0002] Medically, catheterization generally uses disposable catheters of materials such as rubber and plastics. During the treatment of some patients, the catheterization process cannot be completed with a catheter alone, and a urethral dilator is also required. However, most urethral dilators are solid, and catheterization cannot be completed during operation and use. When encountering multiple operations and treatments such as difficult catheterization, urethral stricture dilation, urethral reunion, bladder blood clot removal, and auxiliary indwelling rubber catheter, a single catheter or urethral dilator cannot be completed. In order to complete the operation and treatment, the cooperation of the two is required, repeated disinfection or replacement is required during use, and the operation and use are cumberso...
