The specific embodiment

With reference to accompanying drawing 1 to 7; A kind of upper limb nerve prosthese integral body that is used for hemiplegia disease patient provided by the present invention roughly is " L " type structure; It comprises FES orthosis 11, the orthosis electrode connecting line 12 that links to each other with FES orthosis 11, and the control box 13 that is used for controlling orthosis work with control module.

FES orthosis 11 comprises arm support 111, the wrist brace 112 that links to each other with arm support 111, be installed in the short bent flesh support of thumb on the wrist brace 112 113, be installed in arm support overcoat 114 above the arm support 111, be installed in the electrode slice 115 of movable adjusting position in the arm support overcoat 114.

Arm support 111 is used for supporting patient's arm, and this arm support just in time adapts with the distinctive symptom posture of hemiplegia disease patient, and the outside of arm support 111 is with arm support overcoat 114.This arm support 111 adopts the ABS material with excellent mechanical property, thermal property and good environmental adaptability to process.

Wrist brace 112 connects together with arm support 111, is used for supporting patient's palm portion.For the palm that makes the patient can be comfortable be placed on the said wrist brace 112, wrist brace 112 surfaces are slick arc-shaped curved surface.Wrist brace 112 adopts the ABS material with excellent mechanical property, thermal property and good environmental adaptability to process.

The short bent flesh support 113 of thumb is installed on the wrist brace 112, is used to support thumb.Should process on the short bent flesh support 133 of thumb by silica gel material and be fixed with electrode slice 115.The short bent flesh support 113 of this thumb can be adjusted between 0-90 ° with the angle of horizontal plane as required, and in order better to adapt to kniesiological principle and human comfort, as preferably, the angle of present embodiment employing is roughly 30 °, wherein 30 ° the most suitable.

Arm support overcoat 114 is installed in above the arm support 111, is used for carrying patient's arm and electrode slice 115.The arm support overcoat 114 inner places that contact with patient's arm adopt softish cotton material to process, and the part of outer wrap arm support 111 adopts softish Corii Bovis seu Bubali material to process.The outside of this arm support overcoat 114 is provided with bandage 1141, is used for fixing patient's arm, and simultaneously, four electrode slices 115 are installed in the arm support overcoat 114, and can adjust its position as requested.In addition, be provided with VELCRO above the bandage 1141, convenience and patient's dismounting and fixing.

Electrode slice 115 is used to be pasted on patient's Different Acupoint, and the electricity irritation that control box 13 is sent acts on patient's impaired muscle through electrode slice 115, makes it recover motor function.This electrode slice 115 adopts good biocompatibility, and the material of human non-toxic evil is processed.

Control box 13 is used to control the work operation of FES orthosis 11, and through orthosis electrode connecting line 12 and be installed in FES orthosis 11 inner electric wires and send electricity irritation to electrode slice 115.The switch of control FES orthosis 11 is arranged on the said control box 13, and control box 13 is selected corresponding stimulus intensity according to concrete mode of operation like this.

At first the electrode slice in the FES orthosis 11 115 is pasted on above patient's the Different Acupoint; Be fixed in above the arm support 111 through the arm of bandage 1141, and palm and thumb are placed on wrist brace 112 respectively with above the short bent flesh support 113 of thumb the patient.Open the switch of control box 13 then, as shown in Figure 2, the control module in the control box 13 is just sent signal and is given electrode slice 115.Concrete condition according to the patient is carried different electrical stimulation pattern and stimulus intensity.As shown in Figure 3; The electricity irritation that control module in the control box 13 is sent through orthosis electrode connecting line 12, be fixed in the impaired muscle that the inner electric wire of FES orthosis 11 and electrode slice 15 act on the patient, help patient in restoring normal the motor function of upper limb such as to grab, hold.

What should explain at last is; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention has been carried out detailed explanation with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the spirit and the scope of technical scheme of the present invention.
