Description

Thermochromic pads

This work is about a pad, especially a pad whose bag body has different thicknesses on both sides, and contains a gel with different color changes in different temperature ranges.

Cold and hot compresses are a form of physical therapy used to relieve pain and relieve symptoms such as muscle spasms.

Hot compress can increase the temperature of the application site, expand the subcutaneous blood vessels, promote blood circulation, and achieve the effect of reducing swelling and pain relief; it can also relieve muscle spasm, reduce joint stiffness, thereby improving soft tissue flexibility and accelerating recovery, suitable for degenerative diseases Chronic inflammation and pain such as arthritis, shoulder, neck and low back pain or muscle fatigue.

Cold compresses can reduce the temperature of the used site, make the subcutaneous blood vessels shrink locally, achieve the effects of anti-inflammatory, detumescence and reduce subcutaneous bleeding; it can also reduce muscle spasm and pain relief, and is suitable for tissue bruises and ligaments caused by sports or accidental injuries. Acute inflammation and injury such as a strain or ruptured blood vessel, or swelling and pain after surgery.

Regardless of whether it is cold compress or hot compress, it is medically recommended that the appropriate time for each compress is 15 to 20 minutes, and it is performed about 3 to 4 times a day. At present, common cold compresses or hot compresses on the market are compress pads containing gel, which can be used exclusively for cold compresses, exclusively for hot compresses, or for both cold and hot compresses. When the pad is used for ice application, the pad can be placed in a freezer or immersed in ice cubes to cool down so that it can be applied The temperature of the pad is lowered to the temperature of the cold compress. At present, it is recommended that the temperature of the cold compress is 5~13℃; when the pad is used in a hot compress, the pad can be placed in a microwave oven or immersed in hot water for heating to increase the temperature of the pad. To the temperature of the hot compress, the current medical recommendation is that the temperature of the hot compress is 45°C, and it can be adjusted to 50°C if there is clothing.

However, in the clinical application of hot and cold compresses, the temperature of the pads cannot be kept at a constant temperature due to factors such as the temperature and humidity of the external environment, the size of the area of use, or the temperature of the user during the process of cold and hot compresses, making it difficult to maintain a constant temperature after a period of use. Maintain the optimal temperature of hot and cold compresses, resulting in ineffective treatment and other problems; especially for users who cannot distinguish between hot and cold sensations, such as tactile impairment, cognitive impairment, mental disorder, or diabetes, because the temperature of the compressing pad cannot be immediately reflected and replaced in time Pads may lose the therapeutic effect or prolong the recovery time.

The conventional hot and cold compress pad with sensing temperature change uses a temperature sensing device such as a temperature sensor or a sticking thermometer to sense the temperature of the pad, so as to facilitate the user or caregiver to know the current temperature of the pad body, Then it is decided whether to replace the pad, but firstly, the related temperature sensing device is expensive; secondly, the related temperature sensing device is an additional configuration, which must be attached to the pad by means of attachment, fixing or sticking, which will increase the use. or cause discomfort to the site of use or the injured surface, thereby reducing the willingness to use or the efficacy of the treatment. In addition, some conventional cold and hot compress treatment products will be provided with a temperature-sensitive discoloration device on their surface, and the color change will prompt the user or caregiver to know the current temperature of the cold and hot compress treatment product, but the temperature is the temperature between the cold and hot compress treatment product and the outside world. The temperature of the surface contacted by the air is not the actual temperature of the used part or the injured part. There is a real difference in temperature between the two, especially when condensation occurs on the surface of the cold and hot compress treatment products. The user or caregiver misjudges the timing to replace the cold and hot compress treatment product, thereby increasing the treatment cost and wasting care time.

In view of this, how to provide a pad can solve the aforementioned problems, so as to facilitate users or caregivers to accurately determine the timing of replacing the hot and cold pads, improve the therapeutic effect and save the nursing manpower, which has become the subject to be improved by this creation.

The main purpose of this creation is to provide a pad that can be adhered to the used part or the injured part, and can change color with the change of the temperature range of the body, so as to ensure that the hot and cold compress can achieve the best therapeutic effect.
