Sterile super-lubricity antiseep safety catheter structure

The invention relates to a sterile super-lubricity antiseep safety catheter structure and belongs to the field of medical equipment. The sterile super-lubricity antiseep safety catheter structure comprises a catheter body, an air bag and an inflating tube, wherein one end of the catheter body forms a catheter guiding head part, the other end of the catheter body forms a catheter connecting sleeve, and an air bag inflating hole is formed in a cavity wall of the catheter body. Two ends of the air bag and an outer wall of the catheter body form an integrated body, and the middle of the air bag and the outer wall of the catheter body form an inflating cavity. The inflating tube is formed on one side of the catheter connecting sleeve. The sterile super-lubricity antiseep safety catheter structure is characterized in that the diameter of a catheter connecting sleeve cavity is gradually expanded in the direction far away from the catheter body, a seal ring is formed on a cavity wall of the catheter connecting sleeve cavity, a guiding head is fixed at the tail end of the catheter guiding head part, an inflation valve matching sleeve is arranged at the tail end of the inflating tube in an expanded mode, and an inflation valve is arranged on the inflation valve matching sleeve in a matched mode and comprises a valve body and a valve. The sterile super-lubricity antiseep safety catheter structure guarantees that the expanded air bag is in good contact with an inner wall of the bladder, pain of patients is reduced, the intubation speed is improved, the sealing effect is good, convenience is provided for X-ray radiography, the antibacterial and smoothness effect is guaranteed, and the sterile super-lubricity antiseep safety catheter structure is hygienic and safe.
