Pressure transducer SA1 can detect predefined moulding pressure P
1(for example, than atmospheric pressure high 5.6 kPas (Kpa) pressure) and be higher than moulding pressure P
1Abnormal pressure P
2(for example, than the pressure of atmospheric pressure high by 8.2 (Kpa)), pressure transducer SA2 can detect predefined negative pressure pressure P
3(for example, forcing down the pressure of 6.0 kPas (Kpa)) than atmosphere.In addition, because pressure transducer SA1, SA2 are the pressure transducers that can only detect two pressure respectively, so, though in order to detect above-mentioned 3 pressure P
1, P
2, P
3And used two pressure transducers, but if can detect 3 pressure P
1, P
2, P
3, then also can use 1 pressure transducer.
With the detected pressure of pressure transducer SA1, SA2, pass to sequencer 370.And,, pass to piezometer 306, and be represented as the pressure of air bag 202 with the detected pressure of pressure transducer SA1.In addition, piezometer 306, shown in green usually, but at abnormal pressure P
2The Shi Bianwei redness.
In addition, overlap effective control system B, A is the same with the endoscope-use control system, its detailed description of Therefore, omited.
Below, endoscope-use liquid collecting jar 330 is described.Supply with the pipe 310 that deflates to air bag 220, have the pipeline that is connected with the air bag air taking port 218 of airbag type endoscope 210 by check-valves 332, pass through the pipeline that check-valves 334 and liquid collecting jar 330 are connected with air bag air taking port 218.
To air bag 220 air supplies the time, air supplies to air bag 220 through check-valves 332, during air in extracting air bag 220 out, attracts air from air bag 220 through airtight liquid collecting jar 330 and check-valves 334.
When attracting under air bag 220 disruptive states, body fluid also is attracted with air, but because the liquid collecting jar 330 of said structure, body fluid is left in the liquid collecting jar 330.Therefore, can prevent that body fluid from flowing in the air-bag control device 300.In addition, because the structure of the effective liquid collecting jar 340 of cover is also identical with endoscope-use liquid collecting jar 330, its detailed description of Therefore, omited.
Below, describe the action of sequencer 370 in detail with reference to the flow chart of Figure 10～Figure 13.In addition owing to utilize the air bag controlled of endoscope's side that sequencer 370 carries out identical with the air bag controlled of sleeve pipe side, so below the air bag controlled of endoscope's side only is described.
Figure 10 is the general flowchart of expression sequencer 370 actions.On this figure, sequencer 370 judges whether to have imported from hand switch 304 the decompression instruction (that is the disconnection of endoscope's on/off switch SW 4) (step S10) of air bag 220.When having imported the decompression instruction, then carry out reduced pressure treatment shown in Figure 11.
Equally, sequencer 370, judge whether to have imported the pressurization instruction (that is the connection of endoscope's on/off switch SW 4) of air bag 220 and whether imported the pause instruction (connection of pause switch SW5) (step S20, S30) that keeps air bag 220 pressure from hand switch 304.Then, when having imported the pressurization instruction, carry out pressurized treatments shown in Figure 12, when having imported pause instruction, carry out time-out shown in Figure 13 and handle.
In addition, on the key top of endoscope's on/off switch SW 4 and endoscope-use pause switch SW5, be respectively equipped with as shown in Figure 9 green LED, White LED, this green LED, White LED are lighted when switch connection.In addition, on sleeve pipe on/off switch SW 6, the effective pause switch SW7 of cover, also be respectively equipped with green LED, White LED.
Below, with reference to the flowchart text reduced pressure treatment of Figure 11.
At first, sequencer 370, the time T that will be used for the intervalometer of timing is returned zero (step S102), then, makes the control system A action (step S104) of reducing pressure.That is, as illustrated in fig. 9 electromagnetic valve VA1, VA2 and VA3 are disconnected respectively and drive decompression pump PA2.
Subsequently, according to detection signal, judge whether the pressure in the pipe 310 has reached predefined negative pressure pressure P from pressure transducer SA2
3(step S106) is when reaching the negative pressure pressure P
3The time, stop decompression action (step S108).
Then, make the solenoid action of electromagnetic valve VA2, and switch to position a stopping with the action of reducing pressure.And, because along the diameter of the set air supply pipe in the insertion section 212 of airbag type endoscope 210, fully littler than the diameter of pipe 310, so Once you begin attract (decompression), then the pressure at air bag 220 reaches the negative pressure pressure P
3Before, the pressure in the pipe 310 reaches the negative pressure pressure P earlier
3, and stop the decompression action.But, when the pressure of air bag 220 does not reach the negative pressure pressure P
3The time, the pressure in the pipe 310 can rise once more, and becomes than negative pressure pressure P
3Greatly.At this moment, sequencer 370 begins the decompression action once more according to the detection signal of pressure transducer SA2.Repeat to reduce pressure so repeatedly action beginning with stop, then can making the pressure of air bag 220 reach the negative pressure pressure P
3
On the other hand, do not reaching the negative pressure pressure P
3The time, judge from the time T of decompression action beginning whether reached 30 seconds (step S110).Subsequently, reaching before 30 seconds, when repeating step S104, S106, S110 handle, judging whether unusual (for example, pipe 310 breaks away from air bag air taking port 218).
Above-mentioned when unusual when detecting, the time T of intervalometer is returned zero, and buzzer call (step S112, S114).In addition, be configured in the shutdown switch SW2 that is located on the device body 302 and the red LED be located on each the key top of the shutdown switch SW3 on the hand switch 304 is lighted.
Then, judged whether to press any one (step S116) among shutdown switch SW2 or the SW3,, stopped buzzer call (step S118) when being judged as when pressing.On the other hand, when shutdown switch SW2 or shutdown switch SW3 are not pressed, judge and whether passed through 20 seconds from the time of buzzer call, when having passed through 20 seconds, automatically stop buzzer call.
In above-mentioned decompression action, in case reported unusually with buzzer, usually, the operator of double-balloon endoscope after pressing shutdown switch SW2 or shutdown switch SW3, confirms whether pipe 310 comes off.
Below, with reference to the flowchart text pressurized treatments of Figure 12.
At first, sequencer 370 returns the time T of intervalometer to zero (step S202), then, makes the control system A action (step S204) of reducing pressure.That is, electromagnetic valve VA3 is connected, and drive pressurization pump PA1.
Subsequently, according to detection signal, judge whether the pressure in the pipe 310 has reached predefined moulding pressure P from pressure transducer SA1
1(step S206) is when reaching moulding pressure P
1The time, further judge whether to reach abnormal pressure P
2(step S208).And, when not reaching abnormal pressure P
2The time, stop compression motion (step S210).
Then, make the solenoid action of electromagnetic valve VA1 and switch to position a, to stop to carry out compression motion.And, because along the diameter of the set air supply pipe in the insertion section 212 of airbag type endoscope 210, fully littler than the diameter of pipe 310, so air supply (pressurization) Once you begin, then before the pressure of air bag 220 reached moulding pressure P1, the pressure in the pipe 310 reached moulding pressure P earlier
1, and stop compression motion.But, when the pressure of air bag 220 does not reach moulding pressure P
1The time, the pressure in the pipe 310 can reduce once more, and becomes than negative pressure pressure P
1Little.At this moment, sequencer 370 according to the detection signal of pressure transducer SA1, begins compression motion once more.The beginning that so repeatedly repeats compression motion with stop, then can making the pressure of air bag 220 reach moulding pressure P
1
On the other hand, or when carrying out vermicular movement or not stopping compression motion because of unusual (for example, electromagnetic valve VA1's is unusual) of device body 302 because of small intestinal, the pressure in the pipe 310 reach abnormal pressure P sometimes
3At this moment, enter step S212, and judge abnormal pressure P at this moment from step S208
3Whether continued for 5 seconds.
If abnormal pressure P
3Continued for 5 seconds, then the time T of intervalometer has been returned zero, and the buzzer that pipes (step S214, S216).Simultaneously, the red LED that is configured on each key top of shutdown switch SW2, SW3 is lighted.
Then, judge whether among shutdown switch SW2 or the shutdown switch SW3 any one is pressed (step S218), when having been pressed, stop buzzer call (step S220).Then, the action (step S222) of reducing pressure is up to abnormal pressure P
2Reach moulding pressure P
1This action of reducing pressure disconnects electromagnetic valve VA3 and switches to position b and goes up and carry out.At this moment, for example,, also can reduce pressure by switching solenoid valve VA3 even when electromagnetic valve VA1 breaks down and stopped compression motion.
Then, the time T of intervalometer is returned zero (step S224), the operation (step S226) of other switch SW that the disconnection (decompression) that judges whether endoscope's on/off switch SW 4 is operated etc.During 20 seconds after stopping buzzer call certainly, when other switch SW are not operated (step S228), enter step S230, and the action of reducing pressure is up to reaching the negative pressure pressure P
3Till.In addition, in step S226, when judgement has the operation of other switch SW, then carry out air bag controlled according to the instruction of this switch SW.
In addition, in step S218,, then judge whether then to have the operation (step S232) of other switch SW when being judged as shutdown switch SW2 or SW3 when not pressed.In addition,, then stop buzzer call (step S236) if when the state of not pressing shutdown switch SW2, SW3 and not operating other switch SW from buzzer call has been kept 20 seconds (step S234), and the action of reducing pressure, up to the negative pressure pressure P that reduces pressure
3Till (step S230).
On the other hand, return step S206, when the pressure of pipe in compression motion 310 does not reach moulding pressure P
1The time, judge whether the time T that begins from compression motion has reached 60 seconds (step S238).And, before time T has reached 60 seconds, during the processing of repeating step S204, S206, S238, be judged as unusual (for example, pipe 310 is thrown off with air bag air taking port 218).
As mentioned above,, then the time T of intervalometer is returned zero if detect unusually, and buzzer call (step S240, S242).Simultaneously, the red LED that is configured on each key top of shutdown switch SW2, SW3 is lighted.
Then, judge whether among shutdown switch SW2 or the SW3 any one is pressed (step S244), when having been pressed, stop buzzer call (step S246).Subsequently, the time T of intervalometer is returned zero (step S248), and judge whether the operation (step S250) of other switch SW.When not having the operation of other switch SW during 20 seconds after stopping buzzer call certainly (step S252), enter step S230, and the action of reducing pressure, up to reaching the negative pressure pressure P
3Till.
On the other hand, in rapid S244, when shutdown switch SW2 or SW3 are not pressed, judge whether the time T of buzzer call has passed through 20 seconds (step S254), if passed through for 20 seconds, then after automatically stopping buzzer call (step S256) enters step 230, and the action of reducing pressure is up to the negative pressure pressure P that reduces pressure
3Till.
Below, the abnormality detection when air bag 220 breaks is described.
Because along the diameter of the set air supply pipe in the insertion section 212 of airbag type endoscope 210, littler than the diameter of pipe 310, (diameter of pipe 310 is about 6mm, the diameter of air supply pipe is about 0.8mm), when beginning air supply when (pressurization), reach moulding pressure P at the pressure of air bag 220
1Before, the pressure in the pipe 310 reaches moulding pressure P earlier
1, and stop compression motion.But, when the pressure of air bag 220 does not reach moulding pressure P
1The time, because the air in the pipe 310 supply with to air bag 220 by air supply pipe,, and become than moulding pressure P so the pressure in the pipe 310 can reduce once more
1Little.At this moment, sequencer 370 begins compression motion once more according to the detection signal from pressure transducer SA1.
When air bag 220 does not break, the beginning that repeatedly repeats above-mentioned compression motion with stop, then can making the pressure of air bag 220 reach moulding pressure P
1, but when air bag 220 breaks, reach moulding pressure P even repeat the pressure that compression motion can not make air bag 220 for a long time
1
At this moment, in the present embodiment, beginning and stopping (promptly with short period repetition compression motion, the on/off vibration of electromagnetic valve VA1), but the time that the duration of oscillation that has produced when having continued the compression motion of the normal air bag 220 of ratio contraction is fully grown (for example, 40 seconds) time, then be judged as air bag 220 and break, and buzzer call.
Below, handle with reference to the flowchart text time-out of Figure 13.
On the other hand, when in compression motion, having imported pause instruction, make the solenoid action of electromagnetic valve VA1, electromagnetic valve VA1 is switched on position a, and stop compression motion (step S306).
This pause function, for example, while when making airbag inflation that double-balloon endoscope is inserted in big enteral, use.That is, in compare the big large intestine of intestinal tube diameter with small intestinal, the size of air bag has reached tube chamber, and the pressure of air bag does not also rise to predefined moulding pressure P sometimes
1, at this moment use above-mentioned pause function and stop compression motion.
In addition, when the operation double-balloon endoscope, usually,, can judge whether air bag has expanded fully at big enteral according to this fluoroscopy images owing to observe fluoroscopy images.
In addition, in temporarily stopping in decompression action or compression motion, in case Push switch SW5 once more, decompression action or compression motion before then recovering temporarily to stop.And, in temporarily the stopping of decompression action or compression motion, in case pressed pressurization or relief cock (endoscope's on/off switch SW 4), then according to the switch of being pressed, preferential action.
In this embodiment, be at endoscope-use control system A and overlap among the effective control system B, be provided with pressurization respectively and use pump, but also these pumps can be common to endoscope-use and overlap effective with pump and decompression.
In addition, moulding pressure P
1, abnormal pressure P
2, the negative pressure pressure P
3, can distinguish endoscope and sleeve pipe and setting at random.And, make the control of each air bag or expansion or contraction, except the pressure that detects according to pressure transducer carries out, also can detect the air mass flow of supplying with or extracting out from air bag and control to air bag.
