Balloons can actually save lives in a few interesting ways! Here are some examples:
- Medical Uses:
- In hospitals, doctors use balloons during a procedure called angioplasty(通波仔手術). They insert a small balloon into a blocked artery and inflate it to help open it up, which improves blood flow. They also use balloons to place stents, which keep the arteries open.
- Emergency Signaling:
- If someone is in trouble, brightly colored balloons can be used to signal for help or to mark specific locations. This is especially helpful in outdoor emergencies or rescue situations.
- Child Safety Awareness:
- Balloons are often used in campaigns to teach kids about safety, helping to prevent accidents.
- Therapeutic Benefits:
- In therapy settings, balloons can help people express their feelings, especially in art therapy sessions.
- Rescue Operations:
- Large balloons can even be used to lift equipment or supplies to places that are hard to reach.
So, while they might seem like just fun party decorations, balloons can have some serious life-saving uses!
