Apparatus for evaluating standing-aid training
A medical apparatus for standing aid includes a backrest ( 4 ) that has at least one side thereof provided with a crank rocker mechanism that includes a crank mechanism ( 1 ), a triangle linkage mechanism ( 2 ), and a rocker mechanism ( 3 ), the crank mechanism ( 1 ) is rotatably connected to the triangle linkage mechanism ( 2 ) such that an included angle between a second driven link (BE) of the triangle linkage mechanism ( 2 ) and the crank mechanism ( 1 ) is always smaller than 90°, and the crank mechanism ( 1 ) driving the triangle linkage mechanism ( 2 ), the rocker mechanism ( 3 ) and the backrest ( 4 ) connected to the triangle linkage mechanism to perform interactive movement repeatedly along a predetermined curve trajectory in response to a driving force from a drive effect of a driving unit ( 100 ), so that the backrest ( 4 ) connected to the second driven link (BE) assists a trainee in standing up repeatedly by obliquely supporting the trainee's waist.
1. A medical apparatus for evaluating standing-aid training, comprising: a driving unit ( 100 ); a linkage unit ( 200 ); a seat unit ( 300 ); a data harvesting unit ( 400 ), an assessment unit ( 502 ), a control unit ( 503 ), and a backrest ( 4 ), wherein the linkage unit ( 200 ) assists a trainee sitting on the seat unit ( 300 ) in sitting and rising movements by interaction between a crank mechanism ( 1 ) and a rocker mechanism ( 3 ) driven by the driving unit ( 100 ), the assessment unit ( 502 ) assesses a physical condition of the trainee according to a set of data collected by the data harvesting unit ( 400 ), and the control unit ( 503 ) performs real-time adjustments on a training frequency and training duration of the trainee,
wherein a crank rocker mechanism comprises the crank mechanism ( 1 ), a triangular-shaped linkage mechanism ( 2 ), and the rocker mechanism ( 3 ), and
wherein a first apex (B) and a second apex (C) of the triangular linkage mechanism ( 2 ) are connected to the crank mechanism ( 1 ) and the rocker mechanism ( 3 ), respectively, and a third apex (E) of the triangular-shaped linkage mechanism ( 2 ) is connected to a backrest ( 4 ), which is adapted to hold a trainee's shoulders in position so as to assist the trainee's shoulders to move following a shoulder motion curve during the trainee's sitting and rising movements.
2. The medical apparatus of claim 1 , wherein the medical apparatus has at least two crank rocker mechanisms, wherein the two crank rocker mechanisms are symmetrically provided at two ends of the backrest ( 4 ), and further wherein the backrest ( 4 ) is fixedly connected to the third apex (E) of each of the triangular-shaped linkage mechanisms ( 2 ).
3. The medical apparatus of claim 2 , wherein the backrest ( 4 ) is a rectangular backrest fixedly connected to the third apex (E) of each of the triangular-shaped linkage mechanisms ( 2 ), and the backrest is fixedly connected to corresponding fixing points on a second driven link (BE) of each triangular-shaped linkage mechanism between the third apex (E) and the first apex (B) of each of the triangular-shaped linkage mechanisms ( 2 ).
4. The medical apparatus of claim 3 , wherein the data harvesting unit ( 400 ) collects a trainee's exercise data including a trainee's training frequency, training duration, a pressure that the trainee exerts on a footrest ( 17 ) and/or a trainee's biological information that includes a trainee's body height, body weight, heart rate, blood pressure, breathing rate and/or body temperature.
5. The medical apparatus of claim 1 , wherein the backrest ( 4 ) is provided with at least two shoulder straps for fastening the trainee's shoulders and at least one waist band for fixing a trainee's trunk, in which the shoulder straps and/or the waist band are equipped with at least one of the biological information sensor and/or the shoulder motion curve sensor.
6. The medical apparatus of claim 1 , wherein the driving unit ( 100 ) comprises a motor ( 7 ), a long axle ( 9 ), an intermediate axle ( 18 ), and a secondary chain drive low-speed wheel ( 19 ),
the motor ( 7 ) being connected to the long axle ( 9 ) through a primary chain drive mechanism ( 8 ), the long axle ( 9 ) having two ends each connected to a secondary chain drive low-speed wheel ( 19 ), respectively, through a secondary chain drive mechanism ( 10 ), and
each secondary chain drive low-speed wheel ( 19 ) being rotatably connected to one end of the crank mechanism ( 1 ) through the intermediate axle ( 18 ), so that the linkage unit ( 200 ) provides aid based on a drive force of the driving unit ( 100 ).
7. The medical apparatus of claim 1 , wherein the seat unit ( 300 ) comprises a back cushion ( 20 ), a fastening mechanism ( 21 ), a seat support ( 22 ), and a seat cushion ( 23 ),
the seat support ( 22 ) comprising a U-shaped structure and a bar-shaped structure vertically connected to the U-shaped structure,
the bar-shaped structure of the seat support ( 22 ) being adjustably positioned to a vertical tube ( 11 ) of the frame ( 5 ) through the fastening mechanism ( 21 ),
the U-shaped structure having two ends each provided with at least one through hole for fixing and adjusting the seat cushion ( 23 ), and
the back cushion ( 20 ) is attached to one end of the bar-shaped structure.
