Description
Technical field
The invention belongs to the utensil that helps patient or people with disability to walk about, particularly a kind ofly can judge the formula walking aid automatically.
Background technology
Walking is to repeat maximum a kind of actions in the human daily life, and the low reason of walking ability can have a variety of.Comprise that mainly tibialis anterior that the damage of craniocerebral injury, cental system and all kinds of peripheral nervous system pathological changes cause is unable etc.; Most typical disease shows strephenopodia, the drop foot that for example apoplexy, cerebral trauma, spinal cord injury and disease, hemiplegia, cerebral palsy etc. cause.Whether the patient has good walking ability is directly connected to the expectation that their independent living ability, quality of life and recurrence are socially reintegrated.Therefore, in the disease of all kinds of abnormal gaits, the walking ability that recovers the patient is topmost rehabilitation goal.Be example with typical apoplexy, the mental pressure that brings along with aged tendency of population, social change increases and the change of diet structure, and the apoplexy morbidity is in rising trend.China's apoplexy sickness rate is 120-180/10 ten thousand, be 2 times of the U.S., mortality rate 60-120/10 ten thousand, 85% leaves dyskinesia in the survivor, disability in various degree, cause white elephant for family and society, according to the Ministry of Public Health statistics, the medical treatment that pay because of primary disease in the annual whole nation, rehabilitation, nurse fees are near 40,000,000,000 yuan.Therefore, design the walking aid of the more crowd's services of being commonly of a kind of Wearable, and the combined with intelligent warning function, an urgent demand and the trend of social condition now become.
Existing walking aid mainly is divided into three kinds of forms: frame for movement formula, the electricity irritation of implantable neural formula and external electric stimulate formula.The problem that the frame for movement formula exists is that volume is big, and load is heavy, uses inconvenience, easily the patient is caused the skin wearing and tearing, and the profile oddity easily allows the user produce inferiority complex.The problem that the electricity irritation of implantable neural formula exists is to need operation to implant, and has increased the wound to patient, and the material structure compatibility that implants has a big risk, external lead complexity, and the physical disabilities patient should not operate, and the wholistic therapy expense is very high.External electric stimulation formula is divided into Wearable and non-Wearable, and the problem that non-Wearable exists is that the user is inconvenient to use, and some additional intelligence gait analysis functions need doctor's auxiliary setting, and the user is independent operation fully; Price is relatively costly, and market penetration rate is low.
China's utility application description " practical electronic walk helper " (application number 89215145.5; August 14 1991 day for announcing) discloses a kind of electronic walk helper that causes lower extremity movement obstacle patient because nervus centralis is impaired that is applicable to, comprised a controlled pulse generator, foot switch, an a pair of internal electrode and the external protector that matches with it.There is internal electrode in this device, needs operation to implant, and has increased the wound to patient.
Chinese invention patent prospectus " electronic walk helper " (publication number CN86100635A, open day on August 19th, 1987) thus disclose and a kind of animal and human body limb function carried out the instrument that electricity irritation realizes walk help and treatment function, comprise a pulse generator, output voltage selector, pair of stimulating electrodes, walking pace controlling switch and a function expander.This kind walking aid need be fixed on the positive and negative electrode sheet of stimulating electrode under patient's knee joint medial and lateral and a plate electrode is fixed in energising then under the capitulum fibulae, is inconvenient to use.
Existing walking aid uses inconvenient, does not have warning function.Confirm through overtesting, human body is after a large amount of motions, can cause the minimizing of local linked groups such as fatty tissue, and the electric conductivity of tissue such as fat will be far below human body lean tissue mass, so detection by electric conductivity, can judge the content of body fat mass in human body, and then judge whether human motion has surpassed the health limit.
Summary of the invention
The object of the present invention is to provide and a kind ofly can judge the formula walking aid automatically, simple in structure, easy to use, and have the function of when patient's something unexpected happened, reporting to the police.
The technical solution that realizes the object of the invention is: a kind ofly can judge the formula walking aid automatically; comprise Wearable protection structure; be provided with in the described Wearable protection structure a pair of left lower limb electrode and a pair of be right lower limb electrode, comprise that also being attached to Wearable protects structural main frame.
Described walking aid also comprises the healthalert unit, comprising:
The constant current source that is connected with described left lower limb electrode or right lower limb electrode;
The current sensing means that is connected with described right lower limb electrode or left lower limb electrode;
The current comparator and the memory element that are connected with described current detecting;
When user is in not kinestate of health, described constant current source sends constant electric current, and described current sensing means detects this electric current, obtains current intensity and the information of voltage of this electric current, is stored in the memory element, as basic value;
In the user use, described constant current source sends described constant current by Fixed Time Interval, described current sensing means is analyzed current intensity and the information of voltage of described each electric current, described current comparator compares these current informations and described basic value, when departing from basic value when big, described current comparator sends information warning to described main frame, and described main frame sends prompting to user.
Further, the walk help pulse generator that described main frame comprises master controller and links to each other with master controller respectively, alarm, display, switch and power supply, described master controller is used for the generation of control walk help pulse, control is reported to the police sends or stops to send and controlling content displayed, described walk help pulse generator is used for generating a pair of controlled pulse and exports by electrode, described alarm is used for sending or stopping the alarm signal of sounding, display alarm signal and network, the Bluetooth communication alarm signal, described display is used for displays temperature, electric weight, time and warning message content, described switch is in carry out on and off switch control according to user's user demand, left and right sides electrode selector control, the control of stimulus intensity selector switch, alarm switch control and network signal on-off control, described power supply is to each functional module power supply of main frame.
The present invention compared with prior art, its remarkable advantage:
1, compact conformation, easy to use, directly integral type is worn on the shank position or is worn on shank respectively and the waist place; Electrode in vitro is placed in the Wearable equipment, playing the auxiliary treatment effect simultaneously, has also avoided the damage to skin;
2, use hommization, taken full advantage of the intelligent alarm function of wireless network, the patient is in time succoured;
3, simple in structure, cost is low, can be accepted by more consumers.
4, by detecting the variation of shank electric conductivity, and then the variation of analysis shank fat content, thereby draw the exercise intensity of current user, can provide objective and accurate prompting for daily walking training, when reaching certain amount of exercise, can not damage when injected organism tissue because quantity of motion is excessive, and because the technology maturation that adopts, cost is cheap relatively, very is convenient to promote and use.
