What Are Cold Therapy Machines?
Ice therapy machines also known as cold therapy machines are used for cold compression therapy which utilizes the freezing effect in conjunction with compression.
Cold therapy machines incorporate two aspects of the R.I.C.E healing and recovery method. This stands for Rest, Ice, Compression and Recovery; cold therapy machines focus on the Ice and compression phases. 
Cold therapy machines look similar to an ice cooler and utilizes freezing agents such as ice and water. They usually come with a hose; one side of the hose is attached to the container while the other end is attached to a circulation pad, which is placed on a section of the body.
When the ice and water are added to the container, you must then wrap the pad which is connected to the hose, around the body part that requires treatment.
The machine then disperses the cold therapy through the hose and on to the surface of the pad, which is wrapped around the knee, leg, shoulder or other body parts thus compressing the injury in the process.
The compression aspect of the machine helps to remove fluid that has been built up in the area and caused the swelling. While the cold temperature narrows the blood vessels thus temporarily inhibiting blood flow to the injured area.
What are the Benefits?
Medical professionals, along with sports and rehabilitation specialists all agree that compression therapy in combination with cold therapy ranks among the best treatment for injury, inflammation and pain related to your muscular system. 
Cold compression therapy helps to mitigate pain, thanks to its numbing effect, and it does not have the dangerous side effects of over-the-counter medication.
It also helps your tissues repair themselves faster by reducing swelling and inflammation, and increasing nutrients and oxygen to the injured area.
Its other benefits include stimulating blood flow and stimulating the movement of lymphatic fluid which then provides injured tissues with both nutrients and oxygen.

Another option is a detachable tube which allows you to remove it during use if you need to go somewhere.
Some pads are designed to be used only on specific areas such as the knee and won’t work on other body parts.
If you want a product that can be used on different areas, ensure that this is stated in the product description.
