Description

Cystostomy tube

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a bladder fistulization pipe.

Background

Many patients in urology require various fistulization procedures after treatment to help patients recover early, one of the more common procedures being cystostomy. The fistulization tube that will use cystostomy after cystostomy operation carries out the water conservancy diversion, present cystostomy tube generally is the hollow tube that medical rubber made, the front end of this kind of tube is umbelliform or mushroom-shaped protrusion, above have the incision, be used for the discharge of urine and other liquid, carry out cystostomy in suprapubic position during the use, show the bladder antetheca, poke and insert the mushroom head into the bladder with the vascular forceps, the wound of general cystostomy will be less than the mushroom head, just so can make the first card of mushroom be unlikely to fall out on the fistulization mouth, make various liquid in the bladder can follow and get into behind the pipe entering in the incision of all directions simultaneously and get into the honeycomb duct and discharge.

Although the fistulization pipe of above-mentioned structure is convenient operation simple, but need insert mushroom head rigid in the fistulization mouth when the operation, because the size of fistulization mouth will be less than the size of mushroom head, so that with mushroom head card in the fistulization mouth and unlikely to drop, rigid inserts the mushroom head in the bladder, cause the wound to the patient easily, appear painful, hemorrhagic phenomenon, bring very big misery for the patient, medical staff's the work degree of difficulty has been increased, and current bladder fistulization mouth is made with medical latex mostly, it keeps somewhere the time weak, need often change, medical staff's work load has been increased.

Disclosure of Invention

In order to solve the defects existing in the prior art, the utility model provides a bladder fistulation tube, which has simple structure and convenient operation and can reduce the wound of a patient.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a bladder fistulization pipe, includes the pipe, the pipe has a drainage chamber, the front end of pipe be with the entrance point that the drainage chamber is linked together, the rear end of pipe be with the exit end that the drainage chamber is linked together still includes sacculus, passageway, drainage bag and is used for the cutting knife of fistulization, the sacculus sets up on the lateral wall of pipe, and is close to the entrance point, the passageway sets up on the lateral wall of pipe, the passageway with the sacculus is linked together, just a check valve is installed to the import of passageway, the drainage bag pass through the drainage tube with the pipe is connected, the cutting knife sets up in the pipe, just the blade of cutting knife stretches out the entrance point, the handle of a knife of cutting knife stretches out the exit end, still be connected with on the lateral wall of pipe and be used for sealing the shutoff subassembly of exit end.
