Final answer:
The three types of safety devices for needles are needle covers, needle shields, and needleless systems.
Step-by-step explanation:
The three types of safety devices for needles are:
- Needle Covers: These are plastic covers that can be placed over the needle after use to prevent accidental needle sticks. Needle covers are commonly used in healthcare settings to protect healthcare workers from potential injuries.
- Needle Shields: These devices have a shield or guard that covers the needle during use. The shield retracts or covers the needle after use to prevent accidental needle sticks. Needle shields are often used in settings where there is a high risk of needle sticks, such as emergency departments.
- Needleless Systems: These devices eliminate the use of needles altogether. They use technologies like air pressure or fluid displacement to administer medications or draw blood without the need for a needle. Needleless systems are commonly used in intravenous drug administration or blood collection.
