The abbreviation of "weight bearing control "orthosis" is WBC in English. It was invested 16 billion yen by the Ministry of Health, Labor and Welfare of Japan and was invested by Kawasaki Heavy Industries Co., Ltd. (responsible for electronics); smc Co., Ltd. Corporation (responsible for air pressure); Takasaki Prosthetics Co., Ltd. (responsible for prosthetic equipment) and the Japanese National Rehabilitation Center for Disabled Persons, who is responsible for clinical rehabilitation research, jointly participated in the successful development. It combines electronics, sports medicine, orthopedics, rehabilitation He has applied for patents in Japan, the United States, Europe, China, etc.
Types
WBC is divided into intelligent type, overall simple type, inner pillar type, front type (type A, type B) and left and right linkage type.
Features
Regarding this wbc walking suit, it is different from the current walking suit in that it has a variable foot expansion device. The upper and lower changes of the waist are not obvious when walking. In addition, The rigidity of the equipment is high, and the body weight can be moved smoothly from the support phase to the swing phase, and less energy is consumed when walking.
Structural composition
Pelvic and trunk support mechanism: The structure of this part consists of a thoracolumbar brace and a long lower limb brace. The hip joint (wbc limiter) is between the two thighs. ) link to further control the movement changes of the two thighs.
Solar telescopic device: The variable structure of the sole of the foot is composed of upper and lower parts. When the sole of the foot expands and contracts, it is combined with the signal of the electronic device to complete the telescopic drive change of the sole of the foot.
Microcomputer system: It is composed of a microcomputer processed by an 8-digit CPU. The crutches are equipped with a control switch that can drive the soles of the feet to telescope, allowing for smooth steps. The further power source is liquid carbon dioxide. , an electronic system on the sole of the foot can control gas consumption.
Sensor: The sensor can detect the front and back position of the left and right feet of the device.
Power source: The driving source used in order to be able to walk independently is liquid carbon dioxide.
Cane: The cane is equipped with a switch that can control the expansion and contraction of the sole of the foot.
Clinical trial evaluation
Clinical trial evaluation: The four domestic rehabilitation hospitals for disabled people are the National Rehabilitation Center for Disabled Persons, Chiwatari Onsen Hospital, Toyama Prefectural Takashi Hospital, and Hyogo Prefectural Society The Fukuji Career Comprehensive Center is responsible for the clinical research. A 3-month clinical trial was conducted on 4 patients with paraplegia of both lower limbs. Photo 2 of the trial results. The results of the trial were that they were able to step very smoothly and the continuous walking distance exceeded 515m (action pressure 0.25mp) can achieve a walking cycle of 2.2 to 2.9 seconds (walking rate 41 to 45 steps/min), which is better than what we originally expected
