1, take a packet of unopened used bubble bath powder, tear open the package, and soak the medicine bag in boiling water for 5- 10 minutes, while stirring constantly to speed up the drug precipitation.

2. Adjust the water temperature of the bathtub to about 37 degrees, and the amount of water should be above the patient's chest. Then squeeze the medicated bath bag repeatedly with both hands to help the effective components in the medicated bag dissolve out.

3. When the patient enters the bathtub for medicated bath, pay attention to the ventilation of the room at this time. At the same time, we should pay attention to the change of water temperature when taking a medicinal bath. The water temperature should be kept at about 37 degrees and the bathing time should be 20-40 minutes.

4. After the bubble bath, the patient does not need to wash his body with clear water, but can directly dry it with a pure cotton bath towel. At this time, patients can apply some emollient cream or emulsion according to their own situation.
