Biology 8 Lesson 12: Practice: Practice first aid and bandage for broken bones
1. Summary of theory
– Causes of bone fractures in humans are: work accidents, traffic accidents, carelessness in life.
– In the elderly, the ratio of bone marrow decreases, so the bones are spongy, brittle, and easier to break than young people.
– When broken bones, children’s bones often heal faster than adult bones, especially the elderly.
– To protect bones, when participating in traffic, it is necessary to note: Follow traffic safety laws, wear helmets…
2. Practice first aid and bandages
a. Practice first aid and bandages
– Step 1: Put 2 wooden splints (or bamboo) on the broken bone.
– Step 2: Line the brace with gauze (or soft cloth) folded thickly at the ends of the bones.
– Step 3: Forced positioning in 2 places of splint head and 2 sides of broken bone.
– Apply the wooden splint to the outside of the forearm.
– The brace should be from elbow → hand.
b. Forearm bone fixation tape
– Step 1: Use a medical bandage (or cloth) to wrap tightly from the elbow to the wrist.
– Step 2: Make a forearm strap to the neck (arm and forearm form a right angle).
– How to wrap the bandage: from the inside to the outside (from elbow → wrist).
– How to hold the tape: hold the tape upside down.
c. femur fixation tape
– First aid bandage the victim in the lying position.
– The brace should be from the rib to the heel.
– Tied fixed at the body.
– Wrap the bandage from the ankle.
3. Report on practice results
The groups take turns to evaluate the performance report
