Recently found in the clinic, many patients in the injury after the hot compress, aggravating the swelling of the injury site, delaying recovery, and now to introduce a scientific homemade ice bag for ice Now on the market can buy a variety of ice bags, can be broadly divided into two kinds, containing freezing medium and does not contain freezing medium. The ice bag without media is more effective, using ice and water mixture as a medium, the surface temperature of this ice bag is constant, the role of lasting. But I still recommend the use of homemade ice bags, not only because of the cheap (almost zero cost), but more importantly, the safety and effectiveness of homemade ice bags are guaranteed. How to make homemade ice bags Materials: medium size plastic bags (supermarket to buy, two at a time), ice (refrigerator homemade), tap water. Do ice bag steps are simple, but there are a few notes: 1, generally with 1 part ice + 2 parts water, ice and water mix to account for the ice bag capacity of 1/2 can. 2, sealing, first the air above the water, in the position near the mouth of the bag knot (1) not close to the water knot (2) nor half a bag of air half a bag of water (3) This has three advantages: ① ice bag will not be bulging, placed when not easy to slip, ② increase the contact area between the ice bag and the skin, ③ no air inside the ice bag, so the ice will not cause the surrounding is ice and water in the middle is the air, so that the ice Evenly. 3, after sealing and tying, outside and then a layer of plastic bags, plastic bags of varying quality, make a watery Jinshan is a mess, especially not yet removed from the affected friends, but also contaminated wounds. 3, the timing of icing acute injury: icing should be done at the first time of injury, the earlier icing pain and swelling, the better; in the next 2 to 3 days can also be iced, until the swelling subsides. If the first few days after the injury is not iced, the injured area is still painful and swollen, can also be relieved by icing, but the effect to be discounted. Although more and more people know that the saying “ice within 24 hours and heat after 24 hours” is not true, we often see patients with swollen feet like steamed buns due to heat application during the acute period, and the swelling will be slow to go down later. Post-operative rehabilitation: Ice therapy is essential for post-operative rehabilitation in sports medicine. In the case of the knee joint, for example, icing can reduce the pain of leg bending exercises, reduce tissue congestion and edema around the knee joint, and reduce the occurrence of ossifying myositis. Ice is generally carried out as soon as possible after rehabilitation exercises, so be prepared before the exercise ice bag, for the joint swelling, pain is more obvious patients, leg bending exercises can also be used between the ice to reduce swelling, pain. 4, the method of ice pack ice bag with ice and water mixture as a medium, the room temperature should be appropriate to put a little more ice, because the high room temperature ice melts quickly, if the ice soon all melted into water, the temperature of the surface of the ice bag will begin to rise, the second half of the ice effect will be affected. The advantage of homemade ice packs is to use a transparent plastic bag, you can always see the ice and water mixture melting when icing. The first time you use an ice pack, you can put a thin towel on the ice part, do not wrap the ice pack, ice is generally maintained for 15 to 20 minutes, so it is best to let the ice melt away in about 20 minutes. Used a few times will know how much ice is most appropriate to put, so that neither waste to ensure the ice effect. After mastering the rule, you can also use thin towels wrapped in ice packs for ice. The frequency and number of ice packs can be increased to once every 2 to 3 hours if necessary, depending on your actual situation. For parts with bony prominence ice (such as fibular tuberosity, tibial tuberosity, femoral medial epicondyle, etc.), ice time should be strictly controlled, and it is best not to directly touch the ice pack to the skin to avoid frostbite.
