An oncology bladder drug delivery device

Abstract

The invention discloses a bladder drug delivery device for medical oncology, which belongs to the technical field of medical devices. The rear end of the catheter is formed with a drug delivery tube head; the front end of the catheter is formed with an elastic film; the end of the elastic film is formed with an elastic connection ring; the outer side of the elastic film is fixedly connected with a plurality of elastic support rods; The front end of the elastic support rod moves to the outside of the opening part; the expansion of the elastic film can abut against the inner wall of the bladder to isolate the bladder from urine. The invention can make the medicine or cleaning liquid directly act on the inner wall of the bladder; the anti-shedding air bag is provided, which can prevent the catheter from accidentally slipping out of the body during the intubation process; During cleaning, the liquid medicine will not be diluted, which is conducive to the full exertion of the efficacy of the medicine, accelerates the treatment speed of the patient, and reduces the pain of the patient.
