Upper limb external skeleton device

Abstract

The invention provides an upper limb external skeleton device. The upper limb external skeleton device is installed on a wheelchair and used for assisting a patient suffering from upper and lower limb dysfunction in upper limb movement and active exercise. The upper limb external skeleton device is characterized by comprising a connecting and supporting mechanism, a shoulder joint motion mechanism, an elbow joint motion mechanism and a wrist joint motion mechanism, wherein the connecting and supporting mechanism is used for being connected with the wheelchair and supporting the external skeleton of the upper limb of the patient, and comprises a wheelchair fixing rod, a first wheelchair locking clamp, a supporting frame, a pulling rod and a single-end locking clamp; the shoulder joint motion mechanism is used for enabling the patient to do shoulder joint exercise and comprises a supporting disc, a rotating piece, an upper arm supporting piece and an upper arm rotating shaft piece, and when rotating, the rotating piece and the upper arm supporting piece drive the shoulder joints of the patient to stretch and retract; the elbow joint motion mechanism is used for enabling the patient to do elbow joint exercise and comprises an upper arm fixing piece, an upper elbow joint connecting piece, a lower elbow joint connecting piece and a forearm fixing piece; the wrist joint motion mechanism is used for enabling the patient to do wrist joint exercise and comprises a grip, flexural springs, a forearm adjusting rod and a forearm supporting piece which are connected in sequence.

Description

technical field [0001] The invention relates to a rehabilitation training appliance, in particular to an upper limb exoskeleton device. Background technique [0002] In September 2015, the "2015 Global Observation Index on Aging" report released by HelpAge International pointed out that the global population aged 60 and over is about 901 million, accounting for 12.3% of the world's population. This proportion will reach 16.5% by 2030. Globally, there are already more people over 60 than children under 5, and by 2050 there will be more people over 60 than under 15. The report also shows that China currently has the largest elderly population in the world. According to the latest data released by the National Bureau of Statistics, by the end of 2016, there were 150 million people aged 65 and over in my country, accounting for 10.8% of the total population. The population aged 60 and above has reached 230 million, accounting for 16.7% of the total population, and according to...

Problems solved by technology

[0004] However, clinical rehabilitation often pays attention to the rehabilitation training of lower limb motor function, and pays less attention to the rehabilitation training of upper limb function and hand function. Moreover, the current routine rehabilitation training is performed manually by medical staff, while the rehabilitation treatment of upper limb function requires more and more Fine Rehabilitation Training

However, the traditional way of rehabilitation is mainly for doctors to provide "one-to-one" or even "many-to-one" auxiliary occupational therapy for patients, which is time-consuming, laborious, and expensive, and ordinary families cannot afford it.

In addition, a wearable exoskeleton is a rehabilitation aid that can be worn on the patient's body to assist the patient in rehabilitation training. There are also a variety of upper limb exoskeleton robot products at home and abroad, but these active devices are generally bulky and expensive. , the average person cannot consume it. Due to these characteristics, this type of product is usually used in large public medical institutions, and its popularity is not high.
