Background

Mastitis is a common disease affecting the health of young and middle-aged women. The disease is mostly generated in postpartum, most of the disease is primiparous women, the disease is a common disease in puerperium, and is one of the reasons for postpartum fever, mild people cannot feed milk to infants normally, severe people need surgery treatment, but can be prevented as soon as possible or treated in time after discovery, and the disease can be avoided or alleviated; when the disease is caused, general poisoning symptoms such as high fever, cold tremor and the like often occur, the breast on the affected side is enlarged in volume, locally hardened, reddened, tenderness and throbbing pain exist, and the normal life of women is seriously influenced. After delivery, a disposable anti-galactorrhea pad is basically used to prevent the leakage of milk and the contamination of clothes during breast feeding. The existing disposable anti-galactorrhea pad commonly used in the market is composed of a surface layer, a core layer and a bottom layer, and the anti-galactorrhea pad can only absorb redundant milk and does not have the cold compress function. The conventional anti-galactorrhea pad does not have any relieving effect when the breast of a mother is red, swollen, hot and painful during breast feeding; even a portion of the nursing pad may cause the temperature of the breast to be higher due to poor air permeability, resulting in discomfort in use.

In order to reduce the temperature of the breasts, the breasts can be properly cold compressed, thereby relieving the congestion of the breasts, slowing the secretion of milk, and relieving the pressure and pain of the breasts. Most of the existing cold compress are mechanisms such as towels, ice bags, cooling pastes, water filling, air inflation and the like, and the cold compress is inconvenient to use, complex in structure, high in cost and inconvenient to clean; some ammonium nitrate is blended into water to play a role in cooling, so that the cost is high at one time. Sometimes, the massage effect is achieved by cold compress, hot compress, medicine compress and slight vibration, and the performance is often lacked. At present, a small device which can rapidly refrigerate and heat a cold compress or hot compress carrier, has low power consumption and is convenient to use is lacked. Common designs can be found in chinese patents 201710909074.0, 201520816172.6, 201721327260.5, 201910608375.9, 201510584496.6, etc.
