Therefore we take round-robin algorithm to handle it in the task of same level-one.
(1.2) it is directed to above-mentioned pneumoperitoneum instrument
The pneumoperitoneum instrument includes proportional control valve, switch electromagnetic valve, gas bleeder valve, mass-air-flow sensor and baroceptor,
Wherein:
The proportional control valve, the switch electromagnetic valve, the gas bleeder valve, the mass-air-flow sensor and the air pressure transmission
Sensor is arranged on supply air line, and is connect with the central control unit；The mass-air-flow sensor is for detecting institute
State the throughput parameter of supply air line；The baroceptor is used to detect the pneumatic parameter of the supply air line；Wherein, described
Supply air line is the pipeline that the pneumoperitoneum instrument inputs gas to patient's body lumen；
The central control unit is small in the pneumatic parameter for obtaining the throughput parameter and the pneumatic parameter
When preset first pneumatic parameter, according to the throughput parameter and preset Standard Gases flow parameter output pwm signal, institute
Pwm signal is stated for the switch time ratio of the control valve to be adjusted, to realize to the air-flow in the supply air line
Amount parameter is adjusted；It is also used to close the ratio when the pneumatic parameter is greater than or equal to first pneumatic parameter
Control valve and the switch electromagnetic valve；It is also used to open and lose heart when the pneumatic parameter is greater than or equal to the second pneumatic parameter
Valve；Wherein, second pneumatic parameter is greater than first pneumatic parameter；
It will be appreciated that supply air line is referred to as output pipe, i.e., out of pneumoperitoneum instrument output gas to patient's body lumen
Gas piping.
It will be appreciated that gas here can be carbon dioxide gas.
It will be appreciated that pneumatic parameter is pressure, throughput parameter is gas velocity.
It will be appreciated that proportional control valve, switch electromagnetic valve and the gas bleeder valve being subsequently noted are arranged at supply air line
On, it is connect with central control unit, and can be connect by metal-oxide-semiconductor with central control unit.
It will be appreciated that central control unit is controlled using PWM algorithm comparative example control valve, specifically: in
The standard throughput ginseng of throughput parameter (for example, air velocity) and setting that centre control unit detects mass-air-flow sensor
Number is compared, if throughput parameter is less than the Standard Gases flow parameter, increases the duty ratio of the pwm signal of output, thus
The pulse width for increasing output end air-flow, to increase output gas flow；And if throughput parameter be greater than the Standard Gases flow parameter,
Then reduce the duty ratio of the pwm signal of output, to reduce the pulse width of output end air-flow, to reduce output gas flow.It can
See, is finely adjusted by the air-flow that supply air line output end may be implemented in the PWM algorithm that central control unit uses, to keep
Near preset Standard Gases flow parameter.
Here, corresponding pwm signal is exported to metal-oxide-semiconductor according to comparison result, opening for proportional control valve is controlled by metal-oxide-semiconductor
Logical and closing, and then the switch time ratio of proportional control valve is controlled, so that the gas in supply air line passes through ratio control
A series of equal high-frequency impulse air-flow of amplitudes is obtained after valve processed, i.e. realization " exhale-stop " formula gas supply.Within the regular hour, this
The tolerance of a little high-frequency impulse air-flows is equivalent to the tolerance of conventional switch mode one switch bout, so can be realized gas in this way
The accurate control and gas transmission of flow are steady.Here, the switch time ratio of comparative example control valve is adjusted, and may be implemented to arteries and veins
The width of qi of chong channel ascending adversely stream is adjusted, and then changes the air-flow size of supply air line output end.
It will be appreciated that the air-flow size of supply air line output end is adjusted by using PWM algorithm realization, in turn
The pressure of the output gas of supply air line is adjusted in realization, since PWM algorithm is accomplished that the fine tuning to throughput,
Adjusting to output gas pressure is also fine tuning.In practical applications, detect in baroceptor pneumatic parameter (for example,
Pressure) less than in the case where preset first pneumatic parameter, it can realize the tune of gas pressure indirectly using above-mentioned PWM algorithm
Section.It is possible that the pneumatic parameter (for example, pressure) that baroceptor detects occur exceeds or reaches preset first gas
The case where pressing parameter, such situation are possible as the failure of pneumoperitoneum instrument a part and lead to not through above-mentioned PWM algorithm
The air pressure of output gas is adjusted in the mode being finely adjusted, and can close proportional control valve and switch electromagnetic valve at this time, i.e.,
Stop the output of supply air line, until the pneumatic parameter that baroceptor detects is again less than the first pneumatic parameter.
But when appearance can not reduce supply air line air pressure by way of closing proportional control valve and switch electromagnetic valve
The case where when, in order to avoid leading to the generation of dangerous situation because crossing hyperbar, gas bleeder valve can also be set in pneumoperitoneum instrument, let out
Air valve can be set on supply air line, and connect with central control unit, when central control unit determines that baroceptor is examined
When the pneumatic parameter measured is greater than or equal to the second pneumatic parameter, then gas bleeder valve is opened, starts to lose heart, until in supply air line
Air pressure is under the first pneumatic parameter.
It will be appreciated that the second pneumatic parameter is greater than the first pneumatic parameter.When the pneumatic parameter that baroceptor detects
When more than or equal to the first pneumatic parameter, proportional control valve and switching control pilot are closed.When the air pressure that baroceptor detects
When parameter is greater than or equal to the second pneumatic parameter, then on the basis of closing proportional control valve and switching control pilot, opens and lose heart
Valve.
Certainly, proportional control valve and switch electromagnetic valve can be simultaneously closed off when being not required to gas supply, prevents proportional control valve
Inside appearance machinery is stuck, is not closed completely and leaks, and realizes the double protection to supply air line.
In practical applications, the baroceptor of the input gas atmosphere for detecting carbon dioxide tank can also be set,
To monitor the gas flow in carbon dioxide tank, alarm is issued when it is lower than particular value, reminds medical staff.
Comparison is realized using PWM algorithm due to being provided with proportional control valve in pneumoperitoneum instrument, and by central control unit
The switch proportional time of example control valve is adjusted, to realize the fine tuning to flow parameter in supply air line, and then realization pair
The fine tuning of air pressure adjusts the gas flow in supply air line by no ladder, and then realize precisely and steady to pneumoperitoneum pressure
Adjusting, solve switch valve opening and closing moment brought by air pressure instantaneous variation, video jitter problem, improve image quality.
In some embodiments, incorporating chamber lens device can also include storage unit, in which:
The storage unit connects the central control unit, for storing the corresponding data set of multiple age brackets；
It is corresponding, the multiple age bracket options of human-computer interaction screen display, and for detecting the multiple age
When any option in section option is selected, trigger signal is sent to the central control unit；
The central control unit is also used to when receiving the trigger signal, according to the option selected corresponding year
Data set corresponding to age section, determines the air pressure recommendation and throughput recommendation for being directed to the age bracket, and the air pressure is pushed away
It recommends value and the throughput recommendation is shown on the human-computer interaction screen.
In practical applications, all age group may include: newborn, children, adult, the elderly etc..
It in practical applications, may include a plurality of record content in the data set of each age bracket, every record content can be with
Including air pressure, throughput, the access times under the gentle flow set of the air pressure, abdominal cavity Pressure Inflation to specified air pressure threshold value model
Average time used and this record within the scope of gas mean temperature, abdominal cavity Pressure Inflation to specified air pressure threshold value when enclosing interior
The timestamp of content.For example, { p:8, s:20, ts:20, c:20, t:480, st:1528969758 }.Wherein, p is pressure, and s is
Throughput, ts are access times, and c is gas mean temperature, and t is the average time used, and st is timestamp.
It will be appreciated that medical staff can select any of multiple age bracket options to select on human-computer interaction screen
, central control unit is extracted from storage unit by the corresponding data set of selection option, and then calculates throughput recommendation
With air pressure recommendation, and two recommendations are shown on human-computer interaction screen, for medical staff's reference, for example, according to air pressure
Above-mentioned first pneumatic parameter and/or the second pneumatic parameter is arranged in recommendation, and above-mentioned standard air-flow is arranged according to throughput recommendation
Measure parameter.
Here, for each age bracket, corresponding throughput recommendation and air pressure recommendation can be all calculated, thus
When calculating recommendation, it is contemplated that this feature of the difference of different age group, so that recommendation more has reference value.
Gas temperature on average in above-mentioned data set is depending on the temperature that repeated detection arrives, it is therefore desirable to setting temperature
Sensor is spent, temperature sensor can be set on the supply air line, connect with the central control unit, for detecting
State the gas temperature in supply air line.
Wherein, central control unit can determine that the air pressure recommendation and the throughput are recommended using following steps
Value:
A1, the suitable score value that every record content is calculated using the first formula, first formula include:
In formula, g is to be suitble to score value, a1、a2And a3For weighted value, tsmaxFor access times in a plurality of record content
Maximum value, tmaxFor time used average in a plurality of record content maximum value, c is to record abdominal cavity in content in this
Gas mean temperature when within the scope of Pressure Inflation to specified air pressure threshold value, t are to record abdominal cavity Pressure Inflation in content in this
The average time used within the scope of to specified air pressure threshold value, ts is to record the access times in content in this.
Wherein, the central control unit can specifically calculate the weighted value in first formula according to third formula
a1, the third formula includes:
a1(t)=a0e-25(t-1)
In formula, t is all numbers in the case where being chronomere with week where the timestamp of current record content, timestamp
Closer, all numbers at place are smaller.
For example, if the timestamp of current record content within nearest one week, t 1；If the time of current record content
Stamp is within nearest two weeks, then t is 2.
Wherein, three weighted value a1、a2And a3And be 1, i.e. a1+a2+a3=1.
A2, using the air pressure in record content corresponding to the maximum value in obtained multiple suitable score values as the gas
Press recommendation and using the throughput in the corresponding record content of the maximum value as throughput recommendation.
It will be appreciated that the more proof air pressures of access times and the combination of throughput are better in record content, it is average
Temperature is better closer to body temperature, and the shorter inflate the time used the better, integrates, g value is higher, it was demonstrated that corresponding air pressure and
The combination of throughput is more suitable for patient, thus here using maximum g value it is corresponding record content in air pressure as
Air pressure recommendation, using the throughput in the corresponding record content of maximum g value as throughput recommendation.
In some embodiments, central control unit can also carry out the record content in the data set in storage unit
It updates or deletes, to guarantee the data validity of data set.
Wherein, the process that central control unit is updated the data set in storage unit includes:
The pneumoperitoneum instrument in use, first time abdominal cavity air pressure and default pressure difference in specified threshold
When maintaining preset duration, to current gas pressure, current throughput, current gas temperatures, this abdominal cavity Pressure Inflation to specified air pressure
Time used and timestamp in threshold range are recorded；If in current record content including the current gas pressure and described
The record of current throughput, then add 1 to corresponding access times, and be updated to timestamp, is calculated more using the second formula
Average time used and gas mean temperature, second formula after new includes:
In formula, n is updated average time used or updated gas mean temperature, and o is being averaged before updating
Gas mean temperature before time used or update, ts are access times before this update, and r is this abdominal cavity Pressure Inflation
Time used or the current gas temperatures within the scope of to specified air pressure threshold value.
For example, the gas mean temperature at first 10 times is 37.2 DEG C, this gas temperature is 37.1 DEG C, then new gas
Mean temperature is n=(37.2*9+37.1)/10.
Certainly, if not having current record content in storage unit, current record content is added in data set,
And access times are 1.
Here, the update to access times is realized to the mode of access times plus 1, when replacing old using new timestamp
Between the mode stabbed realize the update to timestamp, it is real by way of the old average time used is replaced the new average time used
Now to the update of time averagely used, old gas mean temperature is replaced by new gas mean temperature, realization pair
The update of gas mean temperature.
Wherein, the process that central control unit deletes the record content in data set in storage unit can wrap
It includes: if the item number of the corresponding data centralized recording content of each age bracket of storage unit storage is greater than preset maximum item
Number, then by the least note of access times in the record content of the smallest default number of branches of timestamp in the corresponding data set of the age bracket
Content is recorded to delete.
That is, after the item number of the record content in the corresponding data set of some age bracket is greater than certain item number,
Just the smallest record content of access times in the smallest a certain number of record contents of timestamp is deleted, it in this way can be by the time
The smallest record content of earliest and access times is deleted.
In the conventional technology, in pneumoperitoneum instrument use process, medical staff needs to combine experience to pressure and throughput
It is configured, is difficult in view of temperature and inflationtime the two factors, and here according to patient's gas replenishment process in historical data
In gas temperature, inflationtime, pressure, throughput and access times group be combined into medical staff to provide suitable pressure gentle
The combination of flow.
Comparative example is realized using PWM algorithm due to being provided with proportional control valve in pneumoperitoneum instrument, and by central control unit
The switch proportional time of control valve is adjusted, to realize the fine tuning to throughput parameter in supply air line, and then realization pair
The fine tuning of air pressure adjusts the gas flow in supply air line by no ladder, and then realize precisely and steady to pneumoperitoneum pressure
Adjusting, solve switch valve opening and closing moment brought by air pressure instantaneous variation, video shake temperature, improve image quality.
