Disposable anti backflow drainage bags are mainly suitable for the following groups of people:
1. Patients with urinary system diseases or surgeries
       Patients with urinary system stones： such as kidney stones, ureteral stones, etc., may experience hematuria and stone discharge after extracorporeal shock wave lithotripsy. It is necessary to connect a catheter to an anti reflux drainage bag to drain urine and possible small stone particles to prevent infection caused by urine reflux, which is helpful for the recovery of the urinary system.
       Patients with urinary system trauma: Patients with urinary system injuries caused by trauma, such as bladder rupture, urethral rupture, etc., need to use anti reflux drainage bags during the treatment process. It can extract urine from the bladder or urethra, prevent urine from leaking into surrounding tissues, and prevent external bacteria from flowing back into the urinary system with urine, causing infection, which is beneficial for wound repair.
2. Patients with digestive system diseases or surgery
       Patients undergoing intestinal surgery：such as rectal cancer, colon cancer, etc., may have a drainage tube left in the abdomen after intestinal resection surgery, connected to an anti reflux drainage bag for draining exudate, exudate, etc. from the abdominal cavity. Preventing these liquids from flowing back into the abdominal cavity can reduce the risk of abdominal infection and promote the healing of surgical wounds.
       Patients with pancreatic diseases: During the treatment of acute pancreatitis, there may be an increase in intra-abdominal exudate. By placing a drainage tube in the abdominal cavity and connecting it to an anti reflux drainage bag, exudate containing digestive juices such as pancreatic juice can be promptly extracted, avoiding the accumulation of exudate in the abdominal cavity and preventing reflux from causing infection or other complications, which helps to control and recover the condition.
3. Other patients who require drainage
       Long term bedridden incontinence patients: For some patients who are bedridden for a long time and have urinary and fecal incontinence due to neurological disorders, severe limb disabilities, etc., using anti reflux drainage bags to connect urinary catheters or fistulas can easily collect urine, prevent urine reflux from causing urinary system infections, and also keep the patient's body clean, improve their quality of life, and reduce nursing workload.
      Gynecological surgery patients:such as those with uterine fibroids, ovarian cysts, etc., may have a drainage tube placed in the pelvic cavity after surgery, connected to an anti reflux drainage bag for draining blood and fluid accumulation in the pelvic cavity. This helps to observe postoperative bleeding, prevent fluid reflux and infection, and promote the recovery of pelvic tissue.
