Recently, in the outpatient clinic, many patients have problems in making and using ice packs. The wrong choice of ice packs will not only affect the ice effect, delay the recovery, but even have potential safety hazards. Now I will introduce you to a scientific method of making ice packs for self-made ice packs.
In fact, ice is used in many medical disciplines. For example, shock patients use ice caps to protect brain tissue, and fever patients physically cool down through the ice pack. Among them, the use of ice packs in sports medicine is the most extensive, and the choice of ice packs and ice packs are also very different due to different treatment purposes. The combination of a suitable ice pack and a scientific ice pack can achieve the best and safest ice effect, but we can do it ourselves.
1, Â How to choose an ice pack
A variety of ice packs are available on the market and can be broadly divided into two types, including frozen media and non-freezing media. The medium containing the ice box in the car refrigerator has a cold capacity of up to 6 times that of the same volume of ice. The ice pack is convenient and efficient in refrigerating and preserving, but since the initial surface temperature is too low and not constant, it is not good or even unsafe for limb ice application, and sometimes causes frostbite. In contrast, ice packs without media have a better effect, using an ice-water mixture as the medium, which has a constant surface temperature and long lasting effect.

But I still recommend everyone to use homemade ice packs, not only because of the cheap (almost zero cost), but more importantly, the safety and effectiveness of homemade ice packs are guaranteed, and even the advantages of the above two types of ice packs can not be compared. ). The hospitalized patients will see that there are special bags and ice machines for ice packs in our wards. In fact, after returning home, everyone can do the best ice packs by themselves.

2, Â How to make ice packs
Ingredients: medium-sized storage bags (purchased in supermarkets, two at a time), ice cubes (made in the refrigerator ice tray, or to the KFC edge), tap water.
The steps to make an ice pack are simple, but there are a few caveats:
1 ), generally use 1 part of ice + 2 parts of water, ice water mixed to account for 1/2 of the capacity of the ice bag.
2 ) When sealing, first discharge the air above the water surface, knot ( A ) near the mouth of the bag, do not cling to the surface of the water ( B ), and do not wear half a bag of air ( C ). This has three advantages: 1 the ice bag will not be bulging, it will not slip easily when placed, 2 increase the contact area between the ice bag and the skin, 3 there is no air in the ice bag, so the ice will not cause the air around the ice water. In case, make the ice even.
 
 
3 ) After the seal is tight, a layer of fresh-keeping bags will be placed on the outside. The quality of the fresh-keeping bags will be uneven. If you get a water, you will be embarrassed, especially those who have not yet removed the line, and will also pollute the wounds.
3 , the timing of ice
Acute injury: Ice should be applied at the first time of the injury. The earlier the ice is, the better the pain relief effect will be; the next 2 to 3 days can also be iced until the swelling subsides. If there is no ice applied in the first few days after the injury, the injured part is still painful and swollen, and it can also be relieved by ice application, but the effect is to be discounted. Although more and more people already know that "ice within 24 hours, after 24 hours hot" argument is wrong, clinic or due to acute phase often see hot, like bread as suffering from swollen feet Friends, late again The swelling will be slow.
Postoperative rehabilitation: Ice therapy is essential when rehabilitation after sports medicine. Taking the knee joint as an example, ice application can alleviate the pain of bending legs, reduce congestion and edema around the knee joint, and reduce the occurrence of ossifying myositis. Ice is usually carried out as soon as possible after the rehabilitation exercise, so you should prepare the ice pack before the practice. For patients with joint swelling and pain, the interval between the bending exercises can also reduce swelling and pain through ice.
4 , the method of ice
Use an ice-water mixture as a medium for ice packs. When the temperature is high, place a little more ice. Because the ice cubes are high at room temperature, if the ice cubes quickly turn into water, the temperature on the surface of the ice pack will begin to rise. The effect of ice in the second half will be affected.
The advantage of the homemade ice pack is that it uses a transparent fresh-keeping bag to see the melting of the ice-water mixture at any time during the ice application. For the first time using an ice pack, you can put a thin towel on the ice pack. Don't wrap the ice pack. The ice pack is usually kept for 15 to 20 minutes, so it is best to let the ice melt in about 20 minutes. After a few times, I know how many ice cubes are most suitable, so as to avoid wasting a guaranteed ice effect.
After mastering the law, you can also wrap the ice pack with a thin towel for ice. The frequency and frequency of ice application can be increased to every 2 to 3 hours if necessary according to your actual situation. For ice-covered areas with bony prominence (such as humeral head, tibial tuberosity, femoral condyle, etc.), it is necessary to strictly control the ice time, and it is best not to directly contact the ice bag to avoid frostbite.
