Description
Technical Field
The invention relates to the technical field of female breast self-examination gloves.
Background
Mammary gland diseases are diseases derived from mammary gland-related tissues such as mammary gland, fat, lymph, blood vessel, and nipple. The breast diseases comprise inflammatory diseases of the breast, benign lesions of the breast, malignant tumors of the breast, congenital dysplasia, gynecomastia and the like. In the modern life of high working strength, high living pressure and irregular diet and sleep, the incidence of various breast diseases is obviously increased, many women often suffer from the trouble, pay attention to the health condition of the women, the diseases can not stay on the bodies of the women for too long time, the breasts are found to have pathology only at the first time, and the breasts can be checked and treated at the first time to obtain the best effect. Breast self-examination is of great benefit. For example, many women have fibrocysts, but since many people know that the fibrocysts are a common problem, even if the fibrocysts are felt, the fibrocysts are not concerned much, can be benign and malignant, and are easily confused with mastitis and breast cancer, and because the fibrocysts are common and common, the fibrocysts are slowly invisible, and the fibrocysts cannot be ignored easily. By using the female medical self-checking gloves, the breast state can be preliminarily judged at home, the self breast condition can be known, the trouble of frequently registering and seeking medical services is avoided, the self-checking is frequently carried out, the problems are found in time, and the best treatment opportunity can be obtained. The breast self-examination performed monthly is very important, and in order to find various breast diseases in time, a woman over 20 years old should perform the breast self-examination once monthly. The breast self-examination glove is simple and easy to operate, improves the sensitivity of breast self-examination and the lesion detection rate to the maximum extent by amplifying the touch sense and the feeling of an object, and is a household health care product which is convenient to use.
The touch amplification effect of the gloves in the current market is still to be improved, the lumps on the body of a patient are not easy to touch, and the small gloves are not easy to touch. The glove has a problem that the touch feeling is affected by air inflow because of poor elasticity. In addition, the stuffy feeling is easy to generate after the gloves are worn. At the moment, the female breast self-examination glove which is made of more suitable materials, has good air permeability and moisture permeability and large elasticity and can amplify touch feeling and is used for palpation is needed.
