Flushing the catheter can be done with a syringe or saline connected to the catheter through an infuser. Catheter flushing with a syringe should be done by disconnecting the urinary catheter from the area where it is connected to the drain tape, then connecting the syringe to the end of the catheter and body and pushing saline into the catheter. If the catheter is with a side tube, saline can be withdrawn with a syringe and injected through the side tube. On the advice of your doctor, 500 ml of saline, fed through the urinary catheter into the bladder, closes the urinary catheter, and then releases the catheter over a five-minute period of time, and the saline outflow will act as a flushing of the urinary catheter. The urinary catheter needs to be replaced in a month or so to avoid causing prolonged urinary tract infection. Let the patient drink more water, if the patient is a long-term bedridden patients, abdominal massage can be carried out to stimulate the bladder, prompting the patient to have regular urination. If there is any discomfort, consult a doctor promptly.
