Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
FIG. 1 to FIG. 2 is please referred to, Fig. 1 is a kind of specific reality of cryotherapeutic instrument temprature control method provided in an embodiment of the present invention
Apply the step flow diagram of mode；Fig. 2 is a kind of specific reality of cryotherapeutic instrument temperature control equipment provided in an embodiment of the present invention
Apply the structural schematic diagram of mode.
In a specific embodiment, the cryotherapeutic instrument temprature control method, comprising:
Step 1, detect and obtain the surface temperature T of patient skin1；
Step 2, judge the surface temperature T1With preset reference temperature T2Temperature difference δ T whether be lower than deep low gear Tmin；
If surface temperature T1With preset reference temperature T2Temperature difference δ T be lower than deep low gear Tmin, illustrate current therapeutic process apoplexy
The cold wind of machine output has been subjected to more, and the temperature in the affected part of patient reaches expected treatment temperature, without further treating.
If so, step 3, then control closing blower, stop cold air output；
If it is not, whether step 4, detect the gear of presently described blower and the corresponding relationship of the temperature difference δ T preset
The gear temperature difference corresponds in range；This step is for judging whether the gear of current blower needs to adjust.
If it is not, step 5, adjusts the gear of the blower, so that the gear of the blower is with the temperature difference δ T described
The preset gear temperature difference corresponds in range.
By detecting the skin temperature in current patents affected part, blower is automatically adjusted according to the difference of preset fiducial temperature
Gear, control start and stop and the air force of blower, effectively prevent that air quantity in therapeutic process is excessive, cold air output is excessive and leads
The situation for causing patient skin frostbite impaired, improves therapeutic effect and the treatment comfort of patient.
For example, in one embodiment, the hand temperature of the patient detected only has 9 DEG C than 10 DEG C of preset reference temperature
Temperature difference is -1 DEG C, is lower than -0.5 DEG C of deep low gear, illustrates to have reached expected therapeutic effect, can stop the operation of blower, stop
The only output of cold air.
And in another embodiment, the hand temperature of the patient detected only has 12 DEG C than 10 DEG C of preset reference temperature
Temperature difference is 2 DEG C, and it is 5 grades that preset blower gear, which correspond to the temperature difference, and when current gear is not 5 grades needs to adjust, no
Then adjusted without gear.
Using cryotherapeutic instrument temprature control method, the difference with existing treatment method is, in existing treatment, entirely controls
Treatment process typically uses the blower of highest gear in output cold wind, and for the patient, and if normal skin temperature
Gap is very big, then be suitably that existing enough therapeutic effects, patient can also endure using the output of powerful cold wind,
And if the skin temperature of patient is only 2-3 DEG C higher than preset fiducial temperature, belong to mild hyperthermia, then using peak power
Blower gear, may make patient skin temperature reduce it is too fast, cause frostbite.
The process that the present invention adjusts gear is not specifically limited.
It in the present invention for the adjustment of the gear of blower, can settle at one go, such as present gear is 3 grades, and temperature
The corresponding gear of poor δ T is 7 grades, and gear gap between the two is more, then can also can adjust step by step with a successive step in place
Whole a successive step in place, can make the revolving speed instantaneous variation of blower very big in place, may cause serious damage for its service life
It loses, therefore in one embodiment of the invention, the gear of the adjustment blower, comprising:
Judge whether the gear of presently described blower gear corresponding with the temperature difference δ T is adjacent；
If so, the gear of the blower is adjusted to the corresponding gear of the temperature difference δ T；
If it is not, the gear of the blower is adjusted to the corresponding gear of the temperature difference δ T by substep.
In such a way that substep adjusts, the gear of blower is gradually adjusted to the corresponding gear of temperature difference δ T, reduces or keeps away
The process of adjustment-free gear is lost for caused by blower, while but also patient can gradually be adapted to, avoiding its skin
The greenhouse cooling on surface is too fast, is also avoided that cool down and causes the increase for the treatment of time excessive slowly.
Preferably, the gear of the blower is adjusted to the corresponding gear of the temperature difference δ T by the substep, comprising:
The corresponding gear value of the temperature difference δ T is obtained using median method；
The gear of blower is adjusted to by the corresponding gear of the temperature difference δ T using median method substep.
It should be pointed out that can be in the present invention blower work during carry out transforming gear, be also possible to by
After blower stops, gear is first transformed into the corresponding gear of degree difference δ T of needs, is then again turned on blower, the present invention for
This adjustment process is without limitation.
Expected gear can more rapidly be obtained using median method, the gear except median method can also be used in the present invention
Lookup mode, the present invention are not specifically limited it.
In one embodiment, temperature difference rank judgment formula: (Tmin+Tmax)/2, Tmin indicates minimum temperature difference value, Tmax
Indicate maximum temperature difference value；Wherein Tmin, Tmax are adjusted according to judging result dynamic；That is, working as temperature difference δ T > (Tmin+Tmax)/2
When, then this T10=(Tmin+Tmax)/2 adjusted is made comparisons with δ T with ((Tmin+Tmax)/2+Tmax)/2 again；
As δ T < (Tmin+Tmax)/2, T10=(Tmin+Tmax)/2, then again with δ T and ((Tmin+Tmax)/2+Tmin)/2
It makes comparisons, the temperature difference range where δ T is derived according to such mode, then finds out corresponding gear.
And the gear of blower is similarly adjusted to by the corresponding gear of the temperature difference δ T using median method substep, just refer to
If current gear is 2 gears, and expected gear is 6 gears, and gear is adjusted to (2+6)/2=4 gear by the first step, so
It is directly adjusted to sixth speed position afterwards or is first adjusted to fifth speed position and then is adjusted to sixth speed position again.
It is, of course, also possible to be solved by the way of tabling look-up, each the temperature difference range is divided, successively sorting out has
Corresponding gear corresponds, and only need to point out that corresponding gear can be found in that range, naturally it is also possible to using above-mentioned
Median method carries out searching corresponding gear, and is not limited to that corresponding shelves can be found once or twice in the present invention
Position, but operation time can be reduced using this kind of mode and search difficulty.
It is general only to work if to carry out gear adjustment due to during blower works due in the present invention
In the process, blower does not stop working, and if the adjustment of multiple gears occurs in a short time, most probably blower is caused to damage
Wound, therefore in one embodiment of the invention, the gear of the blower is adjusted to the temperature difference δ T and corresponded to by the substep
Gear include:
Judge whether the gear of presently described blower is adjusted to the corresponding gear of the temperature difference δ T；
If it is not, judging whether the time between the gear adjustment of presently described blower and the adjustment of last time gear exceeds threshold value；
If so, adjusting the gear of the classification；If it is not, the gear of presently described blower is maintained to adjust it to last time gear
Between time reach threshold value.
For example, just allowing to carry out second of gear adjustment after 10s, can allow for wind in this way after this adjustment
Machine has enough buffer time, it should be pointed out that the gear change number of each gear adjustment is not limited in the present invention
It is fixed, it can be every time adjustment one gear or two gears etc. without limitation.
Since during blower works, the operating temperature in bellows rises, it may occur that the case where burning, because
This, in order to further ensure the reliability of work, in one embodiment of the invention, the cryotherapeutic instrument temprature control method is also
Include:
Detect the default the operating temperature range whether temperature in the bellows of the blower exceeds the blower；
If so, control stops the blower operating.
It should be pointed out that the present invention is not specifically limited the operating temperature range of the bellows of blower, in addition to this
It can also be sounded an alarm after the operating temperature for reaching certain, trapezoidal staff safeguards in time.
In addition to this, the embodiment of the invention also provides give a kind of cryotherapeutic instrument temperature control equipment, including temperature sensor
10, temperature difference gear converter 20 and controller 30, the temperature sensor 10 connect with the temperature difference gear converter 20, are used for
The surface temperature T for the patient affected part that will test1It is transferred to the temperature difference gear converter 20, the temperature difference gear converter 20
Calculate the surface temperature T1The preset reference temperature T prestored with the temperature difference gear converter 202Temperature difference δ T and according to pre-
40 gear of blower deposited and temperature difference corresponding relationship converse the corresponding gear of the temperature difference δ T and are sent to the controller 30,
The gear of blower 40 is adjusted to the corresponding gear of the temperature difference δ T by the controller 30.
Since the cryotherapeutic instrument temperature control equipment is corresponding with cryotherapeutic instrument temprature control method, should have identical
Beneficial effect, details are not described herein by the present invention.
The present invention for the type of temperature sensor 10, installation site without limitation, temperature sensor 10 in the present invention
The affected part that may be mounted at patient is installed away from patient, and the temperature sensor 10 of contact is due to being mounted on patient
Skin may hinder the cold wind of blower 40 to the therapeutic effect of patient, and contactless temperature sensor 10 can be more smart
The skin surface temperature of true detection patient affected part, therefore, the general temperature sensor 10 are infrared temperature sensor 10.
It should be pointed out that preset reference temperature can be the skin of the human normal of staff's setting in the present invention
Temperature can also be with skin temperature when human normal as benchmark with patient certainly the patient of high temperature or swelling
For the skin temperature of body as benchmark, such case is advantageous in that the Surface skin temperature of different human body with meetings such as environment temperatures
It changes, there is biggish error, and on the basis of the normal skin at the close position of same patient affected part, can effectively it exempt
Or reduce because of error caused by crowd etc., and in this case, preset reference temperature can be examined with infrared temperature sensor 10
It is poor that temperature except the affected part and affected part that measure make, and then adjusts 40 grades of different blowers accordingly according to the difference of the temperature difference
, it is further an advantage that not needing additionally to prestore fiducial temperature under this mode, reduce the setting of parameter, improves
The convenience that uses.
In the present invention without limitation for the mode of the progress gear adjustment of controller 30, it can be when needing to adjust
The gear adjustment for adding one or subtracting one is carried out every time, can also be that the mode of direct step section in place is adjusted, but due to human body
Since the skin temperature at different positions is different, even after the blower 40 of equal-wattage gear exports cold wind, it may be due to
The distribution density of the position blood vessel is different, causes the amount of blood transfusion different, so that the speed of temperature decline is different, it is therefore desirable to not
With position it is different at a temperature of treated using different gears, even and same position due to different crowd body
Matter is different, and somebody is suitable in the output cold wind of blower 40 of the gear, and somebody feels colder, and somebody feels the shelves of blower 40
Position is not enough etc..
In order to solve this problem, in one embodiment of the present of invention, the cryotherapeutic instrument temperature control equipment further include with
The controller 30, the blower 40 connect 40 gear adjuster of blower, in presently described blower 40 gear and institute
State the corresponding gear of temperature difference δ T it is adjacent after the gear of the blower 40 is directly adjusted to the corresponding gear of the temperature difference δ T,
Or the corresponding gear value of the temperature difference δ T is obtained using median method and is adjusted the gear of blower 40 using median method substep
To the corresponding gear of the temperature difference δ T.
Temperature difference gear converter 20 in the present invention, can be directly according to actual temperature gap and preset temperature difference
Gear conversion is carried out with the relation table of gear, and the control of the gear of blower 40 can be and change voltage-type or current type
Change blower 40 revolving speed, be also possible to using multicore work by the way of carry out gear conversion.For example, blower 40 has 10 shelves
Position, while having 10 motors, each gear corresponds to the motor work of the numbers of gear steps, and such as the 5th gear corresponds to any 5 therein
Motor work, such as the 6th gear correspond to any 6 gears therein and work, and each motor is enabled to work independently in this way
Complementation influences.
And the corresponding relationship for searching temperature difference and gear, in addition to using other than above-mentioned median method in the present invention, also
Can be by the way of gradually recursion, and due to the limited amount of gear in the present invention, the time needed is less.For example,
Look first at whether temperature difference matches with current gear, if mismatching through the temperature difference is that positive value or negative value carry out shift-up or downshift,
The gear for as needing to adjust divided by the maximum integer in certain unit quantity orientation according to temperature difference simultaneously.
For example, the temperature difference of skin surface temperature and preset reference temperature be 2 DEG C, every 0.5 DEG C be a gear, the two it
Between to be quotient be 4, i.e., it is required that gear adjusted is fourth speed, if in the gear if do not have to adjust, otherwise adjust
It is whole arrive the gear, and if the temperature difference of skin surface temperature and preset reference temperature be 2.3 DEG C, fourth speed to fifth speed it
Between, therefore fifth speed is taken, gear is then adjusted to fifth speed.
Since in the present invention, blower 40 can generate heat during the work time, so that the temperature of its bellows rises, it may
It can be in one embodiment of the invention, described there is a situation where burning, therefore, in order to further ensure the reliability of work
