1. Band-aids are only suitable for wounds with neat, clean incisions and minimal bleeding.

Band-aids are not suitable for all wounds. Generally, bandages are mainly used for small and shallow wounds, especially for cuts that have neat, clean incisions, few bleeding, and do not require suturing, such as knife cuts, cuts, and glass scratches. For large, deep, and foreign body wounds, it is not advisable to use a bandage. In this case, it is necessary to seek medical attention in a timely manner. For contaminated or infected wounds, such as severe skin abrasions, it is not appropriate to use a bandage. Wounds with boils, suppurative infections, and various skin diseases should not be treated with bandages.

2. Clean the wound before use.

When we use band-aids, it is incorrect to always try to make it convenient to just paste things. Before using a bandage, check whether there is any dirt left in the wound. If there is any dirt, clean the wound with physiological saline first, and then apply the bandage. If the wound is deeply pierced by something such as an iron nail, you should immediately go to the hospital for treatment and need to be injected with tetanus antitoxin. After opening a bandage, avoid contaminating the surface. When applying, the medication should be aimed at the wound, and after applying, slightly pressurize both sides of the wound. The bandage should not be too tight to avoid aggravating infection on the wound surface.

3. Do not use it for too long.

First, pay attention to observing the changes in the wound. If, after 24 hours of using a bandage, there is a conscious "pulsating pain" similar to pulse beating at the wound, or there is an overflow of secretion, it should be promptly opened to observe whether there is heat pain around the wound. If so, it indicates that the wound has developed infection and should be treated immediately by a doctor. The second is to pay attention to protecting the wound. After using a bandage, do not often press the wound with your hands. The local area of the wound should be moved as little as possible to prevent collisions and prevent the wound from cracking. The use time of band-aids should not be too long, and they should be changed every day.

4. When applying a band-aid, pay attention to preventing water.

It is not the use of a water resistant bandage that allows prolonged contact with water. "If the bandage does not adhere tightly to the skin around the wound, especially in special areas such as fingertips, knees, and elbows, preventing water becomes impossible.". When using a water resistant bandage, minimize contact with water, pay attention to observing and protecting the wound, and immediately replace it after being soaked in water, otherwise it can easily seep water and cause wound infection.

5. Use medicated bandages to avoid allergies.

Generally, band-aids with and without medication have similar effects, but those with medication can cause allergies. After applying a band-aid, if you feel burning, stop using it immediately.

6. The duration of a band-aid is typically three years.

When purchasing, you should take a look at the outer packaging. Bandaids older than 3 years cannot be guaranteed to be sterile and should not be purchased.
