What kind of catheter is it and what does it do?

A drainova® catheter is a soft, flexible tube made of biocompatible silicone. The catheter is implanted once by the doctor during a short surgical procedure under local anesthesia and can remain in the body for as long as excessive fluid builds up. The part of the catheter with the many small drainage holes is located in the body and the white polyester sleeve in the middle of the catheter is placed under the skin by the doctor. This white cuff fuses with the tissue, preventing the catheter from accidentally slipping out. At the visible end of the catheter is a white safety valve, which can be connected to a gravity bag, soft vacuum reservoir or vacuum bottle to drain the fluid as required or as prescribed by the doctor.

The drainage of the fluid takes about 15 minutes. The catheter is then bandaged with gauze compresses and a waterproof film dressing, which can also be used for showering. The dressing is comfortable, inconspicuous under clothing and not visible to others. The time-consuming, recurring punctures at the hospital or clinic are no longer necessary. The discomfort is efficiently alleviated. You benefit from greater freedom of movement and an improved quality of life.

Everything you need to know as a patient and family

Once the catheter has been implanted, which can be done on an outpatient basis or in conjunction with a very short inpatient stay, you can go home with the catheter. The doctor or nurse treating you will inform ewimed Switerzland AG that you have received a catheter. ewimed Switerzland AG will send you the material for the drainage free of charge by post and we will arrange a training appointment with you or your relatives. A product specialist from ewimed Switerzland AG will come to your home one or two days after you leave hospital and explain to you how to insert the drainage and change the dressing easily and safely.
