Reducing lower back and kidney pain with smart heated kidney belt

Reducing lower back and kidney pain with the thermal support

The lower back muscle strain results from strains and overexertions, creating tension in the muscles and soft tissues around the lower spine. As a result, this restricts proper circulation
and sends pain signals to the brain. Applying heat can help relieve pain from the muscle spasm and related tightness in the lower back through several mechanisms 
a. Heat dilates the blood vessels of the muscles surrounding the lumbar spine. This process increases the flow of oxygen and nutrients to the muscles, helping to heal the damaged tissue. 
b. Heat stimulates the sensory receptors in the skin, which means that applying heat to the lower back will decrease transmissions of pain signals to the brain and partially relieve the discomfort.
c. Heat application facilitates stretching the soft tissues around the spine, including muscles, connective tissue, and adhesions. Consequently, with heat therapy, there will be a decrease in stiffness as well as injury, with an increase in flexibility and overall feeling of comfort. Flexibility is very important for a healthy back. 

Robust and efficient heating elements

The heating elements are made of robust and high-performance graphene material. Graphene is a revolutionary material with excellent conductive properties. Besides the good thermal efficiency, the graphene elements are above all one thing: extremely safe. The material can be used under various climatic conditions, under high mechanical stress, and in humidity and underwater without causing any damage. 

Dynamic heat control

The integrated temperature sensor balances the heat settings especially under low temperature or cold ambient. Under cold surroundings, the heat output drops. The sensor maintains and stabilizes the heating power providing the user an excellent warming experience. Furthermore, the sensor prevents overheating when using the kidney belt in a warm environment.

Surface heating with an exceptional feel-good factor

Compared with conventional heating wires, graphene elements provide even heat over the entire surface. The heating elements are placed across the defined surface and heat up the kidney, pelvis, and lower back area. 

Vulpés Smart Heated Kidney Belt - Butterfly Design

Inspired by nature. 

       perfected by technology.

The shape of the Vulpés kidney belt is based on the butterfly wings and offers warmth for the kidney, back, and pelvic areas. 

Vulpés Smart Heated Kidney Belt

Butterfly Design Structure

The Vulpés heated kidney belt is designed in the shape of a butterfly. The kidney belt profile covers the most sensitive part of the body, the lower back, the pelvic, and the kidney areas. Due to the butterfly structure, the heat can be easily transferred to the most sensitive zones. 

Large heating surface

The Vulpés heated kidney belt has exceptionally large warming surfaces that cover the lower back area. These provide pleasant, comfortable warmth and evenly heat the selected areas. 

With breathable properties

The material composition is based on bamboo fabric which has naturally breathable properties. It creates a pleasant micro-climate inside the heated kidney belt and prevents the accumulation of moisture. The graphene layer is perforated and allows the moisture to escape from the heated belt. The material properties as well as the belt structure provide a high level of wearing comfort, especially during sports and work. 

Vulpés Smart Heated Kidney Belt - Ideal for outdoor sport

Ideal for motion

The ultra-light material properties provide the user freedom of movement without wearing bulky and thick clothing layers. The heated kidney belt can be worn tight to the body beneath the clothing without being limited during sports or work. 
Furthermore, the heated belt structure has been tailored for the lower back to enhance the ergonomics as well as the wearing comfort.

15x times more durable

The Velcro fastener has excellent adhesive properties and is made of high-quality material. It allows the wearer to use the Velcro fastener up to 15 times longer compared to conventional components. 

The high durability increases the overall product lifetime, especially in frequent use.
