Method of use of catheter
1. Lubrication: Before catheter insertion, it is necessary to lubricate with medical lubricant, which can effectively help smooth insertion.

2. Insertion: Carefully insert the lubricated catheter into the bladder.

3. Water injection: Hold the valve sleeve and insert the valve with a syringe without a needle. The water injection volume should not be greater than the calibrated capacity.

4. Take out: When taking out the catheter, insert the empty syringe into the valve according to the method of injecting water, and then take out the catheter after drawing out the water.

5. Indwelling: The indwelling time in the catheter shall not exceed seven days.

 

Precautions for catheter use
1. Maintain a strict aseptic operating environment to prevent infection;

2. Report to the doctor in time if the patient has severe pain and discomfort or blood during the flushing process;

3. When performing closed bladder irrigation, do not go too fast, so as to avoid the patient’s strong desire to urinate, which will lead to bladder contraction and make the flushing solution overflow;

4. If treatment is needed at the same time as catheterization, and the liquid medicine enters the body, it needs to be kept in the bladder for 30 minutes, and then drainage;
