Description

Fixable External Nephrostomy Tube and Drainage Set

technical field

The invention relates to the field of medical equipment, in particular to a fixable external nephrostomy tube and a drainage container.

Background technique

Nephrostomy is suitable for symptoms such as ureteral obstruction, empyema, and ureteral blockage due to advanced bladder cancer, and is suitable for patients after kidney stone extraction surgery. Through nephrostomy, the renal pelvis can be drained, renal function can be improved, and infection of the renal pelvis and renal parenchyma can be alleviated. Specifically, in a nephrostomy operation, an incision is made on the patient's body, a nephrostomy tube is inserted into the renal pelvis, and the renal pelvis incision is sutured after the nephrostomy tube is fixed so that the nephrostomy orifice is kept outside. After surgery, the nephrostomy tube is connected to the ostomy bag, and the patient's urine, pus, and blood are drained into the ostomy bag through the nephrostomy tube.

In the existing nephrostomy operation, the nephrostomy tube can be kept in the nephrostomy channel of the patient by suturing the incision, but a part of the nephrostomy tube still hangs outside the patient's body. In order to prevent the nephrostomy tube hanging from the patient's body from shaking and causing the nephrostomy tube to fall off, the nephrostomy tube is usually fixed to the patient's waist skin with tape, or the external nephrostomy tube is knotted to reduce shaking. If it is fixed with tape, the adhesive area of the tape is small, and the patient's slight movement may also cause the ostomy duct tape and the ostomy tube to be separated from the patient's body. Multiple tapes are required to be firmly fixed, which is not only not reliable enough, but also increases the doctor's workload.
