Description

Electronic ankle joint function instrument

This utility model relates to a kind of patient care instrument, particularly a kind of electronic ankle joint function instrument that prevents patient's intersection point.

In the prior art, various bodily fuctions' instrument has a lot, provides a kind of " rolling type fitness rehabilitation device " as patent 92225495.8, stimulates foot echo area and cave portion with scroll wheel, makes body function obtain adjusting; And " rehabilitation device " that patent 94219655.4 provides is used for lower limb flesh increased functionality and recovery, similar bicycle pedal.Intersection point is the long-term complication due to stiff of stupor, paralysis, lower limb disorder patient, prevent intersection point, the nursing staff will carry out the maneuver ankle joint function to patient and take exercise twice every day, reach one hour at every turn, both wastes of manpower, fall flat again, existing rehabilitation device is not suitable for the functional rehabilitation of ankle joint again.

The purpose of this utility model provides a kind of new electronic ankle joint function instrument, and patient's ankle joint is carried out mechanical passive exercise, keeps the physiology length and the muscular tension of ankle joint normal function mobility and Calf muscle, prevention patient intersection point.

The purpose of this utility model can realize by following technical measures: in the casing of this instrument motor is arranged, reduction box, reduction gearbox output shaft connects drive screw, nut is engaged on the drive screw, be fixed with connecting rod on the nut, screw rod rotates, nut moves vertically, be provided with corresponding its stroke of control of two travel switches with nut, adjust the position of two travel switches, can change the axially movable stroke of nut, pedal is hinged on the support above the casing, the lower end of pedal is provided with chute, the chute of connecting rod on the nut and pedal lower end is hinged, and when nut was mobile vertically, connecting rod promoted the pedal swing.Power supply connects motor through panel, and panel has timing, speed governing, motor commutation function, forms with existing control circuit.During practical application, patient's foot is fixed on pedal, connects motor power, through speed change transmission drive screw, move the every contacting travel switch of nut in the stroke of nut between two travel switches, just commutation is moved, and connecting rod promotes pedal and constantly swings movable patient's ankle joint.

Concrete structure of the present utility model and embodiment are provided by the following drawings:

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is the panel circuit diagram of this utility model embodiment.

The utility model is described in further detail below with reference to accompanying drawing: with reference to Fig. 1, motor [7] is housed in the casing [1], reduction box [6] and panel [8], the panel circuit diagram is seen Fig. 2, drive screw [3] connects reduction box [6] output shaft, motor is through speed change transmission drive screw [3], nut [4] is contained on the drive screw [3], connecting rod [11] is fixed on the nut [4], corresponding two travel switches [2] that are provided with nut [4], [5], travel switch [2], [5] can adjust the position, thereby adjust the stroke of nut, support [12] is arranged above the casing [1], the middle part of pedal [9] is hinged on the support [12], the lower end of pedal [9] is provided with chute [10], and the upper end of connecting rod [11] is hinged in the chute, and nut [4] moves between two travel switches, promote pedal [9] swing, movable patient's ankle joint.According to patient's situation, can adjust mobility, motion frequency, the time of control ankle joint, rehabilitation efficacy obtains medical treatment.

This utility model provides a kind of motor machine passive activity equipment of ankle joint, keep patient's ankle joint normal function mobility, the physiology length and the muscular tension of Calf muscle, also the mechanical movement by muscle improves local blood circulation, and the induced movement sensation, reach the rehabilitation purpose.It is simple in structure, and is reasonable in design, light, inexpensive, effective, is widely used in patient's ankle joint useless prevention and treatment with the property intersection point, and market prospect is boundless.
