How to apply the ice pack?

Prepare materials first: fresh-keeping bags commonly used at home (bought in the supermarket, two at a time), ice cubes (homemade in the refrigerator and freezer) and tap water.

Operating steps: 1. Prepare all items, two at a time, which can be used interchangeably. Two: take a fresh-keeping bag, fill it with a quarter of ice, and tie it tightly. Third, apply the homemade ice pack to the affected area.

The steps of making ice packs are simple, but there are several points to note: 1. Generally, 1 ice +2 water is used, and the ice water accounts for1/2 of the ice bag capacity after mixing; 2. When sealing, first discharge the air above the water surface and tie a knot near the mouth of the bag. Don't tie a knot near the water, and don't half bag air and half bag water. This has three advantages: the ice pack will not bulge and will not slide easily when placed; Increase the contact area between the ice pack and the skin; There is no air in the ice bag, so it will not cause ice water around when applying ice, and there is air in the middle to make the ice evenly applied; 3. After the seal is fastened, put a fresh-keeping bag outside to prevent the wound from being contaminated. The normal method of applying ice cubes to face is to wrap ice cubes or ice packs with pure cotton towels and apply them externally to the affected parts. Generally, it should be applied for 10- 15 minutes, not too long to prevent local frostbite. At the same time, 1 day cannot be used more than 2 times. If the use time of minors and the elderly should be shortened, and the symptoms must be closely observed when ice is applied to the face. If you have symptoms of cold and chills, we need to stop using ice to compress your face. If the symptoms do not improve 3-5 days after applying ice to your face, you need to go to a regular hospital for treatment.
