Bladder drug delivery device for department of medical oncology

Abstract

The invention discloses a bladder drug delivery device for the department of medical oncology, and belongs to the technical field of medical instruments. The bladder drug delivery device comprises a urethral catheter and a liquid discharge port, wherein a liquid discharge tube head is formed at the rear end of the urethral catheter, a drug delivery port is formed in the front end of the urethral catheter, a drug delivery tube head is formed at the rear end of the urethral catheter, an elastic film is formed at the front end of the urethral catheter, an elastic connecting ring is formed at thetail end of the elastic film, a plurality of elastic supporting rods are fixedly connected with the outer side of the elastic film, the urethral catheter is provided with an expanding part capable ofenabling the front ends of the elastic supporting rods to move towards the outer side, and the elastic film can be unfolded to abut against the inner wall of the bladder to isolate the bladder from urine. According to the bladder drug delivery device, a drug or cleaning liquid can directly act on the inner wall of the bladder, an anti-falling air bag is arranged, and thereby the urethral cathetercan be prevented from accidentally sliding out of the body in the intubation process. Part of the bladder can be isolated from urine, and thereby a liquid medicine cannot be diluted when the bladder is directly administrated or cleaned, so that the full exertion of the medicine effect is facilitated, the treatment speed of a patient is increased, and the pain of the patient is relieved.

Problems solved by technology

[0003] However, when directly administering medicine to the bladder, most of the medicine will be diluted by urine and excreted with the catheter, making the medicine effect slow. In addition, for some patients, the inner wall of the bladder is often accompanied by inflammation or festering dead skin, and the bladder has no effect on the absorption of medicine. It is slow and needs to be cleaned before it can be used directly. The above patents cannot meet the actual needs of use
