Description

[Detailed description of the invention] Technical field to which the invention pertains The present invention relates to a device used to drain urine from a patient who has created a ureterocutaneous fistula through a catheter.

Prior art and its problems Urine excreted by a patient who has had a ureterocutaneous fistula created due to impaired bladder function is passed through a catheter inserted into the ureter from the fistula opening and flows into a urine collection bag.
The conventional method is to drain the accumulated urine to the outside by opening the drain hole of the urine collection bag as appropriate. In this case, to prevent the catheter inserted into the ureter from moving, the catheter is fixed to the abdomen using surgical tape or a flat catheter stopper, but the gap between the ureter and the catheter This is often the cause of urine leakage, and currently the only way to deal with leaked urine is to rely on gauze to absorb it. Therefore, the gauze often needs to be replaced, and there is also a high risk of infection due to sores on the skin due to urine absorbed by the gauze or reflux into the ureter.

Purpose of the invention The purpose of the invention is to create a urine collection bag that allows not only urine excreted through the fistula to flow through the catheter, but also all urine leaking from the gap between the ureter and the catheter to the urine collection bag. The object of the present invention is to obtain a device for tube-cutaneous fistula.

Structure of the invention According to the invention, the above-mentioned object is provided with a mounting body that can be closely attached to the fistula opening, and this mounting body has a fixing part of the catheter and a drain port for leaking urine provided at a lower position of the mounting body. , and a cleaning port.

The attachment body is formed into a flat conical or cylindrical shape that is open at least on the side where the fistula opening is attached (bottom side), and a flange is provided on the bottom side so that the attachment body can be attached to the body with a belt. It's advantageous. Alternatively, this flange may be fixed to the body with an adhesive. For the fixing part of the catheter, a hole leading to the outside may be made at an arbitrary position on the side opposite to the bottom side of the attachment body, and the catheter may be inserted and fixed through this hole, or one end of the catheter may be fixed inside the attachment body. It is also possible to provide a part that can fix the catheter.The point is to prevent the catheter led out from the fistula from moving and entering deep into the ureter, or conversely from falling out of the ureter, and to prevent it from falling out of the ureter. Any device may be used as long as it has the function of gently curving and fixing the catheter so that the catheter does not bend midway and become occluded. It is advantageous to provide the drain port for leaked urine at a position that is located below the wearer when the wearer is attached to the body, preferably at a lower position since all the urine leaking into the wearer can be naturally drained.
The cleaning port is provided at the top of the wearable body, and when in use, it is sealed with a stopper, etc. When cleaning, the stopper is removed so that cleaning liquid such as water or chemicals can be injected, or the opening is placed on the top side of the wearable body. It is advantageous to provide a removable sealing lid on the opening, and to clean the inside by removing the sealing lid and similarly injecting a cleaning liquid.

Possible materials for the mounting body include rubber materials (polymer substances that have rubber-like elasticity at room temperature), plastic materials, and the like. The former includes urethane, silicone, synthetic rubber, natural rubber, nitrile rubber,
SBR, CR, BR, ACM or some combination thereof, the latter including polycarbonate, polyethylene, polypropylene, polyvinyl chloride, polyamide, polystyrene, ABS, AS,
PVAC, or a combination of several of them.

When attaching the device to the body, use oil (cream), Novectan spray, Skin Prep, etc. to protect the skin to prevent inflammation caused by urine coming into contact with the skin. It is preferred to use a film-forming agent of.
