Document Type and Number:
WIPO Patent Application WO/2016/037357
Kind Code:
A1
Abstract:
Disclosed is a postpartum rehabilitation device, comprising a handle (17) and an ultrasonic treatment head located at the end region of the handle (17), wherein the ultrasonic treatment head comprises a housing (12), wherein an ultrasonic transducer (26) used for sending ultrasound waves to the uterus of a puerpera is provided in the housing (12), and a first anti-ultrasonic radiation structure (13) used for preventing ultrasound waves from penetrating from the housing (12) is also provided in the housing (12), wherein the first anti-ultrasonic radiation construction (13) comprises a plurality of acoustic resistance layers successively located at the side region of the ultrasonic transducer (26), and two adjacent acoustic resistance layers are respectively made of two kinds of material with a natural impedance Z ratio being greater than 1, wherein Z=ρv, ρ being the density of the materials, and v being the spreading velocity of the ultrasonic in the material; the focal plane distance of the ultrasonic transducer (26) is 5 mm - 100 mm, the working frequency is 0.1 MHz - 5 MHz, and the output power density is greater than 0 W/cm2 but less than or equal to 5 W/cm2. Using the postpartum rehabilitation device for women's postpartum rehabilitation achieves a non-invasive and good rehabilitation efficacy.
