With the parameters such as different light intensity, physical therapy time, physical therapy distance are set to different user every time, specific physiologic parameters may be implemented
Fast accurate transfer.
For step 2 comprising two kinds of technical solutions, i.e. scheme are first is that adjust light intensity by adjustable range big
It is small (because in the case where defaulting light intensity gear, it is each apart from corresponding light intensity magnitude be fixed), scheme is second is that apart from constant
In the case of, light intensity magnitude is adjusted by changing the size of electric current.
Refer to Fig. 8, the scheme one in above-mentioned steps two the following steps are included:
A1: it according to the light intensity data in default physical therapy information, sets the first light intensity value (i.e. target light intensity), and according to the first light intensity
Value obtains corresponding first distance value.The step A1 is specifically included: starting up's instrument, sets physical therapy light intensity numerical value, that is, target
Set physical therapy light intensity numerical values recited is assigned a value of the first light intensity value by intensity level size；From pre-stored database
Distance value corresponding with the first light intensity value is searched for and transferred, and the distance value is assigned a value of first distance value (instrument display screen
The value shown on 11 is defaulted as maximum gear light intensity and the numerical value to measure under default distance, and the default distance is first
Distance value).
B1: driving irradiation head movement is detected under current location between irradiation head and plane of illumination by distance measuring sensor 3
Second distance value.In other words, the distance value changed when second distance value is real time kinematics.
C1: the second distance value is compared with the first distance value, obtains first difference value of the two, and is sentenced
Whether disconnected first difference value is less than preset error range, is to terminate to move, and be irradiated by preset irradiation time, no
Whether then driving irradiation head movement again, then real-time detection its distance difference are less than preset range.I.e. according to the first difference value, drive
Dynamic irradiation head movement, and the second distance value between real-time detection irradiation head and plane of illumination, at first difference value
In (such as error range is ± 5mm) in preset error range.It specifically includes: obtaining first distance difference value, and by described the
One distance difference value is compared with the distance tolerance value of default；When first distance difference value is greater than default distance tolerance value,
Driving device drives irradiation head to move towards the direction for reducing first distance difference；Until first distance difference value is equal to default distance
Tolerance value；When first distance difference value is less than default distance tolerance value, driving device drives irradiation head towards increase first distance
The direction of difference moves；Until first distance difference value be equal to default distance tolerance value, then follow the steps D1.
D1: the default irradiation time in physical therapy information is obtained, and irradiation head continues to irradiate.When the default irradiation
Between the irradiation time that stores when referring to last illumination physical therapy, using the last time, the irradiation time duration of storage carries out this photograph
It penetrates, it can be ensured that the physiotheraping effect irradiated every time is consistent.When this irradiation is irradiates physical therapy for the first time, the default irradiation time
It can be the irradiation duration manually exported.
E1: and then judge that the irradiation current time, (the irradiation current time referred to the photograph that irradiation head is carried out in current time
Penetrate the time) it is whether identical as default irradiation time, it is to enter step F1, otherwise continues to irradiate, it is pre- until reaching
If irradiation time, step F1 is entered back into.
F1: end operation.
As shown in figure 9, scheme two in above-mentioned steps two the following steps are included:
A2: the first light intensity value needed for current plane of illumination is inputted；And transfer pre-stored (storage is in the local database)
The corresponding first distance value of first light intensity value and the first light intensity output-scale-factor.
B2: the second distance value under current location between irradiation head and plane of illumination is detected by distance measuring sensor 3；It transfers
The second light intensity value corresponding with second distance value, and the second light intensity output-scale-factor corresponding with the second light intensity value.Wherein
Light intensity output-scale-factor influences size of current, and the second light intensity output-scale-factor described here is real-time change, in other words,
Size of current can be adjusted by adjusting light intensity output-scale-factor, and then adjusts light intensity magnitude.
C2: the second difference value between the second light intensity output-scale-factor and the first light intensity output-scale-factor is calculated；And
Judge the second difference value whether to be in preset error range that (such as error is ± 5mw/cm2) in, it is to then follow the steps D2.It is no
The size of the second light intensity output-scale-factor is then readjusted, until the second difference value is in preset error range, then is executed
Step D2.
D2: the default irradiation time in physical therapy information is obtained, and irradiation head continues to irradiate.When the default irradiation
Between can be the irradiation time of last storage, using the last time, the irradiation time duration of storage carries out this irradiation, can be true
It is consistent to protect the physiotheraping effect irradiated every time.When this irradiation is irradiates physical therapy for the first time, the default irradiation time can be people
The irradiation duration that work exports manually.
E2: and then judge whether the irradiation current time is identical as default irradiation time, is to enter step F2, otherwise
Continue to irradiate, until reaching default irradiation time, enters back into step F2.
F2: end operation.
The two schemes in above-mentioned steps two are illustrated below by way of citing:
Assuming that the plane of illumination of user is remote apart from physiotherapeutic instruments 20cm, set on the display screen 11 of Phototherapeutic instrument target light intensity value as
60mw/cm2.And when machine default gear (assuming that corresponding supply current size is 2A) exports and distance is 20cm, it reaches
The actual light intensity value of plane of illumination may be 30mw/cm2, in order to ensure the actual light intensity value reached on plane of illumination is 60mw/
cm2, just there are two types of schemes:
1) scheme one: instrument (referring to Phototherapeutic instrument, similarly hereinafter) driving electric pushrod work automatically drives irradiation head movement, and pass through survey
Real-time detection distance away from sensor 3, so that the distance between irradiation head and plane of illumination are reduced to 15cm, and in default light intensity
Light intensity value under gear at 15cm is exactly 60mw/cm2±5mw/cm2, thereby realize irradiation head automatic adjustment with it is illuminated
The distance between face so that the light intensity value being output on plane of illumination in error range with preset target light intensity value
It is identical；
It should be noted that instrument has stored in the case where defaulting light intensity gear irradiation head apart from plane of illumination 0-35cm model in advance
Light intensity value size corresponding to interior different distance is enclosed, such as: the corresponding light intensity value size of 15cm is 60mw/cm2±5mw/cm2, this
After sample sets different target light intensity values in display screen 11, irradiation head that instrument can be detected according to distance measuring sensor 3
Different distance between plane of illumination carrys out automatic adjustable range, so that light intensity value size and target light under respective distances
Intensity values are consistent.
2) scheme two: the distance between the irradiation head of instrument and plane of illumination are constant, and instrument is automatically adjusted to light source (such as
LED etc., is illustrated by taking LED as an example below, not as limit) power supply size of current, thus big to adjust light intensity value
Small (in certain current range, the light intensity value size of LED is directly proportional to supply current size), for example, by the power supply electricity of LED
Flowing size increases to 4A by 2A, so that being just exactly 60mw/cm in the light intensity value at plane of illumination 20cm2±5mw/cm2,
The size that light intensity value is automatically adjusted by irradiation head is realized, so as to be output to the light intensity value size and target light intensity value of plane of illumination
Unanimously.
It should be noted that instrument has stored under different supply currents irradiation head apart from plane of illumination 0- in advance
The corresponding light intensity value size of different distance within the scope of 35cm, such as: at 20cm distance, light is corresponded to when setting supply current as 4A
It is by force 60mw/cm2±5mw/cm2, thus can be according to the difference between the irradiation head detected of distance measuring sensor 3 and user
Distance, to automatically adjust the supply current size of LED light source, so that the light intensity value size under respective distances and target light intensity value
Unanimously.
The specific method for changing LED supply current size has the sides such as the method for automatic adjustment potentiometer, automatic adjustment PWM value
Method.Highlight the method for automatic adjustment PWM value below: assuming that the power supply of LED be maximum output be 4A and can be into
The electric current of the constant-current source that row PWM is adjusted, constant-current source output maintains 4A, by adjusting PWM value, electric current is made to be in pulsed operation
Mode, the average adjusting size between 0-4A.Semiconductor integrated chip LED light source is powered by constant-current source, output intensity with
The output size of current of current source is related.Single-chip microcontroller passes through the PWM wave of output different duty, and adjustable constant current source current is defeated
Out.The length of effective load time of the electric current on LED light source is loaded, that is, the duty ratio of loading current is adjusted, for equivalent
It is the equal of changing the size for loading average current on LED light source, and then to realize the control to LED light source output.
The PWM coefficient namely duty ratio that described light intensity output-scale-factor just refers in fact above, i.e., by adjusting PWM coefficient
It can change average current size, to change light intensity value size.
It for step 3, may be implemented that the position of different shadow surfaces is identified and moved automatically, it is automatic complete
At irradiation.
In the present embodiment, can personalized record different user physical therapy information, reduce repetition when in use and set
The trouble set, while it can be automatically moved to the position that need to be irradiated, reduce manual operation.It specifically, can be according to being previously stored
The multiple affected parts of user image and information characteristics, i.e. acquisition user information and physical therapy information in advance, to realize different affected parts
Automatic irradiation physical therapy.For example, in first time physical therapy, while the user informations such as the identity card of user, face-image are acquired, and
The operation such as take pictures is carried out to plane of illumination, records physical therapy information.Before carrying out second of irradiation physical therapy, after inputting user information,
It can quickly recall the register information of user and the information of first time physical therapy, and provide whether to continue and be set when first time physical therapy
Parameter and the suggestion for irradiating physical therapy for whether carrying out multiple positions automatically.If answer is, when transferring last physical therapy automatically
The parameters of the parameters as this physical therapy such as physical therapy time, light intensity, physical therapy distance that each position was set, and when completion first
After the irradiation physical therapy of wound, main control unit can automatically control irradiation head and laterally or longitudinally move to above second wound, and
Automatic starting irradiation physical therapy.
The specific implementation process of above-mentioned constant intensity output method is illustrated below by citing: irradiating physical therapy for the first time
Before, acquire and save user information and physical therapy information: such as essential information the name of user, identification card number is inputted and
It saves, and takes pictures to user's progress face and affected part, stores, numbers registration.Assuming that there is 3 wound locations, then image taking list
It after member takes pictures respectively to 3 wound locations, can be automatically saved in database, and be respectively designated as wound 1, wound 2, wound 3
It is saved Deng similar number and updates storage library.
Assuming that the irradiation condition of three wounds is respectively as follows: wound 1: irradiation time 1--10min, irradiation distance for the first time
5 grades of 15cm, intensity level；Wound 2: irradiation time 2--15min, irradiation distance 15cm, 5 grades of intensity level；Wound 3: when irradiation
Between 3--20min, irradiation distance 15cm, 4 grades of intensity level.Above-mentioned physical therapy information can be protected simultaneously in first time physical therapy
It deposits.
Before second irradiates, user information is inputted, such as input address name or identification card number (or directly scan identity
Card, medical insurance card, medical card), the physical therapy information when user information and first time physical therapy of user registration can be quickly recalled, and
The suggestion for irradiating physical therapy for whether continuing the parameter set when first time physical therapy and whether carrying out multiple positions automatically is provided, if
Answer is the parameters such as the physical therapy time set when wound when then transferring last physical therapy automatically, physical therapy distance, light intensity as this
The parameter of secondary physical therapy.
After user lies in the position determined on the physiotherapy couch of restriction, the image photography unit automatically scanning of instrument is illuminated
Face, when recognize compare with the wound pictorial information of first time physical therapy storage as completely the same information when, main control unit can be from
Dynamic control driving device (such as cross motor, longitudinal motor) makes it drive irradiation head, is moved to 1 top of user's wound and to manage
It is consistent with when first time physical therapy to treat distance, then starting irradiation physical therapy wound 1, after reaching physical therapy time 10min, instrument is automatic
Close light source output；Coordinate setting when irradiating physical therapy according still further to first time to user's wound 2, main control unit can automatically control cross
Irradiation head is driven to motor, longitudinal motor, when being moved to 2 top of user's wound and making physical therapy distance and intensity level, physical therapy
Between it is consistent with when first time physical therapy, then starting irradiation physical therapy wound 2, reach physical therapy time 15min after, instrument is automatically closed
Light source output；Coordinate setting when irradiating physical therapy then according to first time to user's wound 3, main control unit can automatically control transverse direction
Motor, longitudinal motor drive irradiation head, are moved to 3 top of user's wound and make physical therapy distance and intensity level, physical therapy time
It is consistent with when first time physical therapy, and adjusting intensity level is 4 grades, then starting irradiation physical therapy wound 3, reaches physical therapy time
After 20min, light source output is automatically closed in instrument.For 3 wounds all after irradiation, main control unit control can automatically control transverse direction
Motor, longitudinal motor drive irradiation head to be moved to default standby position, terminate physical therapy.
And to the wound of the non-planar features with bedsore, fistula road etc. with recess, image capturing unit can be right before physical therapy
It is taken pictures and stores image, can be 3 come pairs by distance measuring sensor when being irradiated physical therapy to non-planar features wound
The distance of difference to irradiation head is detected automatically on non-planar features wound, while main control unit can control driving device,
Such as horizontal and vertical motor, irradiation head is driven laterally or longitudinally to move, it is ensured that difference is being irradiated on non-planar features wound
It is all the same at a distance from irradiation head in journey.It in other words, can be same to realize by the ranging to non-planar features wound difference
The dotted scan-type physical therapy of isocandela, the problem of avoiding different location uneven illumination on non-planar features wound.
Assuming that user was since long-term bed obtained hip bedsore, plan is irradiated physical therapy using Phototherapeutic instrument.Bedsore is usual
With surface hole defect feature, the distance of difference to skin surface is different in region, arrives irradiation head light-emitting window certainly
Distance it is also different.Bedsore is as non-planar features wound, and longitudal section is usually in approximate V-type shape, to ensure physical therapy light
Uniformity it is preferable, irradiation head issue light spot diameter should be limited in smaller diameter range.For example assume in distance
In plane at irradiation head light-emitting window 15cm, the general 1cm of spot diameter, and assume that defaulting best physical therapy distance is 15cm, default
Irradiation time is 10min at single skin lesion；Also assume that the non-planar features wound maximum outside diameter that need to be irradiated physical therapy is
8cm, bosom are 4cm apart from skin surface, and maximum outside diameter is that the mean depth under left and right directions and 0-1cm sections of projections is
Mean depth under 1cm, 1-2cm sections of projections is that the mean depth under 1.5cm, 2-3cm sections of projections is under 2cm, 3-4cm sections of projections
Mean depth be 2.5cm, 4-5cm sections of lower mean depths of projection be 3.5cm, 5-6cm sections project under mean depth be
Mean depth under 3.5cm, 6-7cm sections of projections is that the mean depth under 2.5cm, 7-8cm sections of projections is 1.5cm.
Therefore when irradiating 0-1cm sections of corresponding positions, main control unit controls laterally electricity under the real-time detection of distance measuring sensor 3
Machine and longitudinal motor movement, so that irradiation hot spot is just covered on right above 0-1cm sections, and ensure irradiation head light-emitting window to 0-
The distance of 1cm sections of skin lesion central points is 15cm, and after completing 10min irradiation, light source output can be automatically closed in instrument, and controls cross
Irradiation head transverse shifting 1cm to the right is driven to motor, the irradiation of 1-2cm sections of corresponding positions is entered, then controls longitudinal motor
Irradiation head is driven to vertically move 0.5cm downwards, to ensure to be to the distance of irradiation head light-emitting window in 1-2cm sections of skin lesion central points
15cm, then the irradiation physical therapy at second skin lesion of starting automatically.In left and right, transverse shifting completes segment wound on the row
After irradiating physical therapy, instrument can control cross motor and drive irradiation head to backward or to forward movement 1cm, carry out the second row and correspond to area
Between section wound irradiation physical therapy.The rest may be inferred, completes all segments irradiation of this plane of illumination (maximum outside diameter 8cm).
Then physical therapy information according to the pre-stored data, determines the position of next plane of illumination, controls branch by longitudinal motor
Strut moves up and down and/or cross motor controls horizontal cantilever all around moving on T font sliding rail, and irradiation head is mobile
To next plane of illumination.For example, next plane of illumination of aforementioned user's bedsore is in the left front of a upper plane of illumination, such as left
At 4cm, front 5cm, wound maximum outside diameter is 4cm, and bosom is 2cm apart from skin surface.Then pass through longitudinal motor control
Support rod processed moves up 2cm, controls horizontal cantilever by cross motor and is moved to the left on " one " track of T font sliding rail
4cm moves forward 5cm on " Shu " track, reaches the second plane of illumination, opens the physical therapy of second plane of illumination.Similarly,
First determination need to be irradiated the distance of the wound maximum outside diameter and bosom of physical therapy apart from skin surface, and by its maximum outside diameter
Every 1cm is divided into an elementary section, and determines the mean depth under the projection of each elementary section, carries out further in accordance with preceding method to it
Irradiate physical therapy.Irradiation until completing all plane of illuminations.
It can be modeled in advance at each skin lesion, its position is determined by lateral surface sweeping line.Complete a certain transversal scanning
After irradiation physical therapy on line at all skin lesions, main control unit controls cross motor and moves to the starting point of next horizontal scan line
It is dynamic until reaching right above its, so that carrying out next transversal scanning line position corresponds to irradiation physical therapy at skin lesion.In each cross
It is corresponded at variant skin lesion to scan line position, the distance of irradiation head to skin lesion central point is 15cm, luminous intensity and irradiation
Time is that default is identical.
