Abstract
The invention provides an elastic physiotherapy mattress and a preparation method thereof, wherein the elastic physiotherapy mattress comprises a physiotherapy layer, a latex layer and a spring layer, wherein the physiotherapy layer is embedded in the center of the latex layer to form a complete layer body; a spring layer is arranged below the latex layer; the upper end of the physical therapy layer is provided with a traditional Chinese medicine pillow; a long and narrow vertebral groove is arranged under the traditional Chinese medicine pillow, and a plurality of raised massage structure points are arranged at other positions of the physical therapy layer; the physiotherapy layer and the massage structure points are prepared from modified EPE foam. The traditional Chinese medicine pillow disclosed by the invention is wrapped with a large amount of traditional Chinese medicine powder for promoting sleep and resisting and inhibiting bacteria, so that the sleep quality of a human body can be effectively improved, and the growth of mites is inhibited; the spine groove arranged in addition accords with the ergonomic design, so that a user has strong fit when sleeping on the mattress, the latex layer improves the elasticity and the softness of the mattress, and the spring layer at the lowest layer can further improve the bearing capacity of the mattress and prolong the service life.
Description
Technical Field
The invention relates to the technical field of mattresses, in particular to an elastic physiotherapy mattress and a preparation method thereof.
Background
The mattress is an article between a human body and a bed, which is used for ensuring that consumers can obtain healthy and comfortable sleep, the mattress is made of various materials, and mattresses made of different materials can bring different sleep effects to people. With the continuous progress of material culture and technical process, the types of mattresses used by modern people tend to be diversified gradually, mainly spring mattresses, palm mattresses, latex mattresses, sponge mattresses and 3D mattresses, among which the spring mattresses account for a greater proportion.
The magnetotherapy is a method for curing some diseases by applying artificial magnetic field to channels, acupoints and pathological change position of human body, and the special magnetotherapy equipment in hospital has the effect for curing hypertension, arthritis, headache, insomnia, coronary heart disease, gastroenteritis, facial spasm, sprain, contusion and cervical spondylopathy, etc. according to the magnetotherapy principle, the invented magnetotherapy mattress can be used for making people comfortably and uniformly contact with human body when sleeping or lying on the magnetic mattress, so that after the magnet in the mattress and iron element contained in human blood are acted, it can produce massage effect, and can raise health of human body and sleep quality.
According to research discovery, if magnetic field intensity is too big to human body probably produce harmful effects, like dizzy magnetic phenomena such as first dizzy, vomiting, but the current internal concentration of common magnetotherapy mattress on the market is provided with the magnetite to all magnetite are controlled by a unified switch, the strong magnetic field that produces when opening whole magnetite not only does not have the physiotherapy effect, still can lead to dizzy magnetic phenomenon, harm people's health, common magnetotherapy mattress itself simple structure moreover, the function is single, also can't satisfy present people diversification.
