Description

气囊式内窥镜 The endoscope balloon

技术领域 FIELD

本发明涉及一种气囊式内窥镜,尤其涉及与将可自由涨縮的气囊设在内窥镜插入部前端的内窥镜。 The present invention relates to an endoscope balloon, and in particular relates to the sizing of the balloon may be freely disposed in the distal end of the endoscope insertion portion of the endoscope. 另外,本发明还涉及可以实现提高使用双气囊式内窥镜时的安全性的双气囊式内窥镜的气囊控制装置。 The present invention further relates to improvement in safety can be achieved when using a double-balloon endoscope double-balloon type endoscope balloon control device.

背景技术 Background technique

作为取代以往的小肠内窥镜的装置,双气囊式内窥镜为众人所周知。 As a conventional apparatus of substituted intestine endoscope, all double-balloon endoscope is well known. 该双气囊式内窥镜,由在内窥镜前端设有气囊并能向该气囊供给空气*吸出空气的内窥镜、和作为能插入内窥镜的插入部的套管、在管子的前端设有气囊 The double-balloon endoscope, a distal end and a balloon of the endoscope and can supply air to the balloon of the endoscope * aspirated air, and a cannula can be inserted into the insertion portion of the endoscope, the distal end of the tube and a balloon

并能向该气囊供给空气*吸出空气的套管构成(例如,日本特开昭51—11689 号公报(第2页,第l图))。 And air can be supplied into the airbag casing constituting the air aspirated * (e.g., Japanese Patent Laid-Open Publication No. Sho 51-11689 (page 2, FIG. L)).

在双气囊式内窥镜的各气囊上连接着气囊控制装置,分别地向各气囊进行空气供给•空气吸出,以使各气囊膨胀和收縮。 Control means connected to the airbag, the airbag, respectively, each on each double-balloon endoscope balloon air supply • air out, so that each balloon is inflated and contracted.

当将双气囊式内窥镜插入小肠时,在使内窥镜的气囊膨胀并固定在肠管上以后,使套管的气囊收縮并沿内窥镜插入部将套管推进到前端气囊处。 When the double-balloon endoscope inserted into the small intestine, when the airbag is inflated and fixed to the endoscope in the intestine after the airbag sleeve and contraction along the endoscope insertion portion to advance the cannula at the front end of the airbag. 然后再使套管的气囊膨胀,将套管固定于肠管上,然后使内窥镜的气囊收縮并将内窥镜插入部向深部插入。 Then the balloon expandable sleeve, the sleeve is fixed to the intestine, and then the balloon is deflated and an endoscope is inserted into the endoscope insertion portion to the deep portion. 一边重复以上的操作一边进行将由气囊固定的固定点向深部边移动边前进。 Side while repeating the above operations performed by the fixing point of the airbag fixed to the deep portion forward while moving. 当内窥镜插入部形成了复杂的折曲形时,在使两方的气囊膨胀的状态下慢慢地与内窥镜一起将套管拉动。 When the endoscope insertion portion formed in a complicated bent shape, in both of the airbag expanded state the sleeve is pulled slowly with an endoscope. 通过该操作,能不拔出内窥镜前端而使折曲形简单化,縮短被插入的肠管,以便使其能折叠在套管上。 By this operation, the distal end of the endoscope can not pull out the bent shape simplified, shortened bowel inserted so that it can fold on the sleeve. 重复上述的一系列操作,可使将肠管折叠在套管上的肠管的折曲形简单化并向小肠深部插入。 Repeating the above series of operations, the intestine can intestine is folded on the sleeve-shaped bent to simplify the insertion depth of the small intestine.

另一方面,在以往的用于向具有空气管的内窥镜供给空气的内窥镜送气装置中,有检测从装置内的压缩机到与内窥镜连接的连接管之间的密闭空间的压力、使该检测出的压力成为设定压力地进行压力调整并且当检测出的压力异常时、能解除异常状态的装置(日本特开2000—217779号公报)。 On the other hand, conventional endoscope air supply means for supplying air to an endoscope having an air tube, for detecting the closed space from the compressor means to the pipe connection between the endoscope connected to the pressure, the detected pressure becomes the set pressure and adjust the pressure detected when the pressure abnormality, means an abnormal state (Japanese Patent Publication Laid-open No. 2000-217779) can be lifted. 如上所述的内窥镜的气囊或套管的气囊,由于使其膨胀并作为支点,所以有时因施加异常压力而损坏。 Balloon or sleeve of the endoscope as described above, since it expands and as a fulcrum, is sometimes damaged by the application of abnormal pressure. 一旦气囊损坏,当在吸引气囊内的空气并使气囊收缩时,则会吸引到体液,该体液向吸引泵倒流并有凝固堵塞或对电磁阀产生恶劣影响的危险。 Once the balloon is damaged, when the suction air in the balloon and the balloon is deflated, body fluids will be drawn to the suction pump fluid back to the risk of clogging and solidification or have an adverse effect on the solenoid valve.

另外,具有如日本特开2000—217779号公报所述的空气管的内窥镜, Further, an endoscope having an air tube as described in Japanese Patent Publication Laid-Open No. 2000-217779 claim,

是为了检查患部状态而向胃等的体腔内排出种种排出压力的空气的装置,不能如同双气囊式内窥镜那样地一边相互交替地膨胀一边插入。 In order to examine the device air is affected various discharge state to the discharge pressure of the body cavity like stomach, not double-balloon endoscope as another side alternately expanding as the insertion side.

另一方面,在一边相互交替地膨胀一边被插入小肠的深部的双气囊式内窥镜的情况下,当各气囊破裂时,或当与气囊式内窥镜及套管的气囊送气口连接的管子脱落或连接不良时,具有气囊的压力达不到规定施加压压力(固定于肠壁所需要的施加压压力)的问题,另外,还有因小肠的蠕动运动或气囊控制装置的控制系统的动作不良等所导致的气囊压力过高而损伤肠管的问题。 On the other hand, in the case where each side of the double-balloon endoscope expansion side is inserted into the deep portion of the small intestine alternately, the respective bladders when broken, or when the gas supply to the airbag and the airbag endoscope sleeve-joint when a bad connection or the tube off, with a pressure applied to the balloon pressure does not reach a predetermined pressure (pressure applied pressure is fixed to the intestinal wall required) problem, in addition, because of the peristalsis of the small intestine or the air bag control system of the control device malfunction, etc. caused by the air bag pressure is too high and bowel injury problems.

另外,在将双气囊式内窥镜插入到小肠时,有时也使气囊膨胀并插入途中的胃或大肠,特别是大肠,由于其弯曲,所以不使用气囊则不能插入的情况较多。 Further, when the double-balloon-type endoscope is inserted into the small intestine, sometimes the balloon is inflated and inserted into the middle of the stomach or large intestine, especially the colon, due to the bending, it is not often the case can not be inserted using a balloon. 利用气囊的向肠壁固定时的设定压力,虽然被设定为适合于人肠管的一定的压力,但当是管腔直径较大的大肠时,则有气囊的大小虽达到管腔但压力却不能上升到设定压力的问题。 Using a fixed set pressure to the balloon wall, although is set to be suitable for a certain pressure of human intestine, large intestine but larger lumen diameter, although the size of the balloon pressure reaches a lumen but it can not rise to the problem set pressure.

而且,在将空气供给吸引用管、分别与气囊式内窥镜以及套管的各气囊送气口连接时,有将各管子接错的可能。 Further, in the suction air supply tube, when the airbag are connected to each of the endoscope and the balloon air supply port of the sleeve, each pipe there may be wrong connection.

本发明,鉴于这样的情况,其目的在于提供一种当气囊破裂时可以阻止体液向空气供给吸引装置倒流的气囊式内窥镜,及可以实现提高双气囊式内窥镜的使用时的安全性、同时使用方便的双气囊式内窥镜的气囊控制装置。 The present invention, in view of such circumstances, and its object is to provide a safety when ruptured when the airbag may be interesting to prevent fluid backflow balloon endoscope apparatus to the air supply, and can be improved using a double balloon endoscope , while easy to use double-balloon endoscope balloon control device.

SA1 pressure sensor, can detect a predetermined pressing pressure Pi (e.g., a pressure higher than the atmospheric 5.6 kilopascals (Kpa)), the higher the pressure and the pressure P! 的异常压力P2 (例如,比大气压高8.2 (Kpa)的压力),压力传感器SA2,可检测预先设定的负压压力P3 (例如,比大气压低6.0千帕(Kpa)的压力)。 The abnormal pressure P2 (e.g., higher than the atmospheric pressure 8.2 (Kpa) pressure), the pressure sensor SA2, can detect negative pressure P3 set in advance (e.g., a pressure lower than atmospheric pressure 6.0 kPa (Kpa) a). 另外,由于压力传感器SA1、 SA2,都是只能分别检测两个压力的压力传感器,所以,虽然为了检测上述3个压力P" P2、 P3而使用了两个压力传感器,但若能检测出3个压力P!、P2、 P3,则也可以使用1个压力传感器。用压力传感器SA1、 SA2检测出的压力,传给序列发生器370。并且, 用压力传感器SA1检测出的压力,传给压力计306,并被表示为气囊202的压力。另外,压力计306,通常显示为绿色,但在异常压力P2时变为红色。另外,套管用控制系统B,与内窥镜用控制系统A—样,故省略其详细说明。以下,说明内窥镜用集液罐330。向气囊220供给啪出空气的管子310, 具有通过止回阀332与气囊式内窥镜210的气囊送气口218连接的管路、通过止回阀334及集液罐330与气囊送气口218连接的管路。在向气囊220供给空气时,空气经过止回阀332供给到气囊220,在抽出气囊220内的空气 Further, since the pressure sensor SA1, SA2, respectively, are the only two pressure detecting pressure sensor, therefore, although for detecting the three pressure P "P2, P3, two pressure sensors are used, but if detected 3 a pressure P!, P2, P3, it is also possible to use a pressure sensor with a pressure sensor SA1, SA2 detected pressure, and passed to the sequencer 370. the detected pressure of the pressure sensor SA1, pass pressure meter 306, and is expressed as the pressure of the airbag 202. Further, a pressure gauge 306, generally shown as green, but when the abnormal pressure P2 turns red. Further, the control sleeve with system B, the endoscope system control A- like, the detailed description thereof is omitted. hereinafter, an endoscope is supplied with a liquid collecting tank 330. the air popping out of the tube 310 to the balloon 220, 218 is connected through the check valve 332 having a balloon of the endoscope and the balloon air supply port 210 tubing, through the check valve 334 and the canister 330 and the conduit 218 is connected to the balloon air supply port. when air is supplied to the bladder 220, the air is supplied to the airbag 220 through the check valve 332, the air in the balloon 220 is drawn ,从气囊220经过密闭的集液罐330及止回阀334吸引空气。当在气囊220破裂的状态下进行吸引时,体液也与空气一起被吸引,但由于上述结构的集液罐330,体液被留在集液罐330内。因此,可以防止体液流入气囊控制装置300内。另外,由于套管用集液罐340的结构也与内窥镜用集液罐330相同,故省略其详细说明。下面,参照图10〜图13的流程图详细说明序列发生器370的动作。另外,由于利用序列发生器370进行的内窥镜侧的气囊控制与套管侧的气囊控制相同,故以下只说明内窥镜侧的气囊控制。图10是表示序列发生器370动作的概略流程图。在该图上,序列发生器370,判断是否从手动开关304输入了气囊220的减压指令(即,内窥镜通/断开关SW4的断开)(步骤SIO)。当输入了减压指令时,则进行图ll所示的减压处理。同样,序列发生器370,判断是否从手动开关304输入 , From the balloon 220 through a sealed tank 330 and set suction air valve 334 when the airbag 220 is sucked in the state of rupture, bodily fluid is sucked together with air, but since the collection tank 330 above structure, the body fluid is left in the collection tank 330. Thus, the body fluid can be prevented from flowing into the balloon control device 300. Further, since the structure of the sleeve with liquid collecting tank 340 also sets the endoscope with the same tank 330, so the detailed description thereof will be omitted. Referring to the flowchart of FIG. 13 to FIG 10~ detailed operation of sequencer 370 is described. Further, since the airbag control sequencer same side of the balloon control sleeve 370 of the endoscope side, so that the following description only side of the endoscope balloon control. FIG. 10 is a schematic flowchart showing the operation of the sequence generator 370 in this figure, the sequencer 370 determines whether or not the manual switch 304 from the input pressure command airbag 220 (i.e., the endoscope on / off switch SW4 is oFF) (step the SIO). when the pressure command input, the processing is performed as shown in FIG ll reduced pressure. Similarly, the sequencer 370 determines whether the input from the manual switch 304 气囊220的加压指令(即,内窥镜通/断开关SW4的接通)及是否输入了保持气囊220压力的暂停指令(暂停开关SW5的接通)(步骤S20、 S30)。然后,当输入了加压指令时,实行图12所示的加压处理,当输入了暂停指令时,实行图13 所示的暂停处理。另外,在内窥镜通/断开关SW4及内窥镜用暂停开关SW5的键顶端上, 分别设有如图9所示的绿色LED、白色LED,该绿色LED、白色LED,在19开关接通时点亮。另外,在套管通/断开关SW6、套管用暂停开关SW7上也 Bladder pressure command 220 (i.e., the endoscope on / off switch SW4 is turned on) and whether the input pressure of the airbag 220 holding an instruction to suspend (stop switch SW5 is turned on) (step S20, S30). Then, when when the input pressure command, carry out the pressing process shown in FIG. 12, when a pause command is input, the processing shown in FIG moratorium 13. Further, the endoscope on / off switch SW4 and suspended endoscope switch SW5 of the key top, the green LED are provided as shown in FIG. 9, the white LED, the green LED, white LED, is illuminated when the switch 19 is turned on. Further, the sleeve on / off switch SW6, ferrules also on the pause switch SW7

分别设有绿色LED、白色LED。 Respectively, with a green LED, white LED.

以下,参照图11的流程图说明减压处理。 Hereinafter, with reference to the flowchart of FIG. 11 depicts the processing under reduced pressure.

首先,序列发生器370,将用于计时的定时器的时间T回零(步骤S102), 然后,使控制系统A进行减压动作(步骤S104)。 First, the sequencer 370, the timing for the timer time T back to zero (step S102), then the control system A depressurizing operation (step S104). §卩,如图9所示地将电磁阀VA1、 VA2及VA3分别断开并且驱动减压用泵PA2。 § Jie, as the electromagnetic valve VA1, VA2 and VA3 are shown disconnected and the pressure reducing pump 9 PA2.

随后,根据来自压力传感器SA2的检测信号,判断管子310内的压力是否达到了预先设定的负压压力P3 (步骤S106),当达到负压压力P3时, 停止减压动作(步骤S108)。 Then, based on the detection signal from the pressure sensor SA2, it is determined whether or not the pressure in the tube 310 reaches the negative pressure P3 (step S106) set in advance, when a negative pressure P3 is reached, to stop the pressure reduction operation (step S108).

然后,使电磁阀VA2的螺线管动作,并切换到位置a以进行减压动作的停止。 Then, the operation of the electromagnetic solenoid valve VA2 and switched to the position to perform a decompression operation is stopped. 并且,由于沿气囊式内窥镜210的插入部212所设的空气供给管的直径、比管子310的直径充分地小,所以一旦开始吸引(减压),则在气囊220的压力达到负压压力P3之前,管子310内的压力先达到负压压力P3,并停止减压动作。 Further, since the diameter of the air supply pipe along the balloon insertion portion 212 of the endoscope 210 is established having a diameter sufficiently smaller than the tube 310, once started suction (under reduced pressure), the pressure of the airbag 220 at a negative pressure before the pressure P3, the pressure in the tube 310 reaches the first negative pressure P3, and stops the operation under reduced pressure. 但是,当气囊220的压力未达到负压压力P3时,管子310 内的压力会再次上升,并变得比负压压力P3大。 However, when the pressure of the airbag 220 does not reach the negative pressure P3, the pressure in the tube 310 will rise again, and becomes larger than the negative pressure P3. 这时,序列发生器370,根据压力传感器SA2的检测信号再次开始减压动作。 In this case, sequencer 370, based on the detection signal of the pressure sensor SA2 begins operation again under reduced pressure. 这样多次地重复减压动作的开始与停止,则可以使气囊220的压力达到负压压力P3。 Such operation is repeated a number of times under reduced pressure to start and stop, the pressure of the airbag 220 can be made negative pressure reaches P3.

另一方面,在未达到负压压力P3时,判断从减压动作开始的时间T是否达到了30秒(步骤SllO)。 On the other hand, the negative pressure P3 is not reached, a reduced pressure is determined from the operation start time T reaches 30 seconds (step SllO). 随后,在达到30秒之前、重复步骤S104、 S106、 S110处理时,判断是否有异常(例如,管子310与气囊送气口218脱离)。 Then, before 30 seconds, repeating steps S104, S106, S110 when the process determines whether there is an abnormality (e.g., the tube 310 from the balloon air supply port 218).

当检测出上述异常时,将定时器的时间T回零,并且蜂鸣器鸣叫(步骤S112、 S114)。 When the abnormality is detected, the time T in the timer back to zero, and the buzzer sounds (step S112, S114). 另外,被配置在设于装置本体302上的停止开关SW2及设于手动开关304上的停止开关SW3的各键顶端上的红色LED被点亮。 Further, it is provided a stop switch disposed on the apparatus body 302 SW2 and SW3 stop switch provided on a red LED on the top of the keys on the manual switch 304 is illuminated.

然后,判断是否按动了停止开关SW2或SW3中的任意一个(步骤S116 ), 当判断为按动时,停止蜂鸣器鸣叫(步骤S118)。 Then, it is determined whether the stop switch SW2 or pressing any one SW3 (step S116), when the judgment is pressed, the buzzer is stopped (step S118). 另一方面,当停止开关SW2 或停止开关SW3没有被按动时,判断自蜂鸣器鸣叫的时间是否经过了20秒, 当经过了20秒时,自动地停止蜂鸣器鸣叫。 On the other hand, when the stop switch SW2 or not the stop switch SW3 is pressed, it is determined whether the time from the buzzer 20 seconds elapsed, when 20 seconds elapsed, automatically stop the buzzer.

在上述减压动作中, 一旦用蜂鸣器报告了异常,通常,双气囊式内窥镜的操纵者,在按动停止开关SW2或停止开关SW3以后,确认管子310是否脱落。 In the reduced pressure operation, once an abnormality buzzer reported, typically, double balloon endoscope manipulator, or after the stop switch pressing the stop switch SW3 SW2, to confirm whether or not the tube 310 off. 以下,参照图12的流程图说明加压处理。 Hereinafter, with reference to a flowchart of FIG. 12 described pressure treatment.

首先,序列发生器370,将定时器的时间T回零(步骤S202),然后, 使控制系统A进行减压动作(步骤S204)。 First, the sequencer 370, the timer time T back to zero (step S202), then the control system A depressurizing operation (step S204). 即,将电磁阀VA3接通,并且驱动加压用泵PA1。 That is, the electromagnetic valve VA3 is turned on, and driving the pressurizing pump PA1.

随后,根据来自压力传感器SA1的检测信号,判断管子310内的压力是否达到了预先设定的加压压力P,(步骤S206),当达到加压压力P!时, 进一步判断是否达到异常压力P2 (步骤S208)。 Then, based on the detection signal from the pressure sensor SA1, it is determined whether or not the pressure in the tube 310 reaches a predetermined pressing pressure P, (step S206), when the pressure reaches a pressure P!, Further determines whether the abnormal pressure P2 (step S208). 并且,当没有达到异常压力P2时,停止加压动作(步骤S210)。 And, when there is no abnormal pressure P2 reached, to stop the pressurization operation (step S210).

然后,使电磁阀VA1的螺线管动作并切换到位置a,以停止进行加压动作。 Then, the operation of the solenoid and the electromagnetic valve VA1 is switched to the position a, in order to stop the pressurization operation. 并且,由于沿气囊式内窥镜210的插入部212所设的空气供给管的直径, 比管子310的直径充分地小,所以一旦开始供给空气(加压),则在气囊220 的压力达到加压压力Pi之前,管子310内的压力先达到加压压力P,,并停止加压动作。 Further, since the diameter of the air supply pipe along the balloon insertion portion 212 of the endoscope 210 is established, the ratio of the diameter of the tube 310 is sufficiently small, so once starts supplying air (pressure), the pressure in the airbag reaches 220 plus before pressing pressure Pi, the pressure in the tube 310 reaches the first pressing pressure P ,, and the pressurizing operation is stopped. 但是,当气囊220的压力未达到加压压力P,时,管子310内的压力会再次降低,并变得比负压压力P!小。 However, when the pressure of the airbag 220 does not reach the pressing pressure P, the time, the pressure in the tube 310 will be lowered again, and becomes! Smaller than the negative pressure P. 这时,序列发生器370,根据压力传感器SA1的检测信号,再次开始加压动作。 In this case, sequencer 370, based on the detection signal of the pressure sensor SA1 again starts pressurization operation. 这样多次地重复加压动作的开始与停止,则可使气囊220的压力达到加压压力P,。 Such repeated a plurality of times to start and stop the pressurizing operation, the airbag 220 can reach a pressure pressing pressure P ,.

另一方面,在或因小肠进行蠕动运动、或因装置本体302的异常(例如, 电磁阀VA1的异常)而没有停止加压动作时,管子310内的压力有时会达到异常压力P3。 On the other hand, when the result of the small intestine or a peristaltic motion, or due to abnormal (e.g., electromagnetic valve VA1 abnormality) of the apparatus body 302 without stopping the pressurizing operation, the pressure in the tube 310 may reach the abnormal pressure P3. 这时,从步骤S208进入步骤S212,并判断这时异常压力 In this case, step S208 enters the step S212, the abnormal pressure at this time is determined and

P3是否继续了5秒钟。 Whether P3 continued for 5 seconds.

若异常压力P3继续了5秒钟,则将定时器的时间T回零,并且鸣叫蜂鸣器(步骤S214、 S216)。 If abnormal pressure P3 continued for 5 seconds, then the timer time T back to zero, and tweet buzzer (step S214, S216). 同时,被配置在停止开关SW2、 SW3的各键顶端上的红色LED点亮。 At the same time, is arranged in the stop switch SW2, a red LED on the top of each key SW3 lighting.

然后,判断停止开关SW2或停止开关SW3中的任意一个是否被按动(步骤S218),在被按动了时,停止蜂鸣器鸣叫(步骤S220)。 Then, it is judged stop switch SW2 or stop any one whether the switch SW3 is pressed (step S218), when pressed, the buzzer is stopped (step S220). 然后,进行减压动作(步骤S222),直到异常压力P2达到加压压力P!。 Then, under reduced pressure operation (step S222), the abnormal pressure P2 until the pressure reaches a pressure P !. 该减压动作,是将电磁阀VA3断开且切换到位置b上而进行的。 The pressure reducing operation, the solenoid valve VA3 is switched to the OFF position and b carried out. 这时,例如,即使在电磁阀VA1发生故障且停止了加压动作时,通过切换电磁阀VA3也可以减压。 In this case, for example, even when a failure occurs in the electromagnetic valve VA1 to stop the pressurization operation and may be reduced by switching the electromagnetic valve VA3.

然后,将定时器的时间T回零(步骤S224),判断是否有内窥镜通/断开关SW4的断开(减压)操作等的其他开关SW的操作(步骤S226)。 Then, the time T of the timer back to zero (step S224), determines whether or not the endoscope on / off switch SW is OFF operation of the other switches (reduced pressure) operation (step S226) SW4 is. when

21在自停止蜂鸣器鸣叫后的20秒钟期间,其他开关SW没有被操作时(步骤 21 during 20 seconds from stopping the buzzer, the other switches SW has not been operated (step

S228),进入步骤S230,并进行减压动作直到达到负压压力P3为止。 S228), entering step S230, the operation and reduced pressure until a negative pressure until the P3. 另外, 在步骤S226中,在判断有其他开关SW的操作时,则根据该开关SW的指令进行气囊控制。 Further, in step S226, when determining an operation of the other switches SW, the balloon control is performed according to the instruction of the switch SW.

另外,在步骤S218中,当判断为停止开关SW2或SW3没有被按动时, 则判断是否接着有其他开关SW的操作(步骤S232)。 Further, in step S218, when it is determined that the stop switch SW3 or SW2 is not pressed, then it is determined whether there are other operation switch SW (step S232). 另外,若从蜂鸣器鸣叫并没有按动停止开关SW2、 SW3、且没有操作其他开关SW的状态维持了20秒(步骤S234)时,则停止蜂鸣器鸣叫(步骤S236),并进行减压动作,直到减压到负压压力P3为止(步骤S230)。 Further, if the press does not beep from the buzzer stop switch SW2, SW3, and the switch SW is not operated while maintaining the other 20 seconds (step S234), the buzzer is stopped (step S236), and Save pressure action until the pressure reduced until the negative pressure P3 (step S230).

另一方面,返回步骤S206,当在加压动作中管子310的压力没有达到加压压力Pi时,判断从加压动作开始的时间T是否达到了60秒(步骤S238)。 On the other hand, returns step S206, when the pressure in the tube 310 does not reach the operation pressure pressing pressure Pi, the determination time T starting from the pressing operation has reached 60 seconds (step S238). 并且,在时间T达到了60秒之前重复步骤S204、 S206、 S238的处理时, 判断为异常(例如,管乎310与气囊送气口218脱开)。 Then, at time T reaches 60 seconds before repeating steps S204, S206, S238 processing, it is determined to be abnormal (e.g., the tube 310 and the balloon air supply port almost 218 disengaged).

如上所述,若检测出异常,则将定时器的时间T回零,并且蜂鸣器鸣叫(步骤S240、 S242)。 As described above, when an abnormality is detected, then the time T of the timer back to zero, and the buzzer sounds (step S240, S242). 同时,被配置在停止开关SW2、 SW3的各键顶端上的红色LED点亮。 At the same time, is arranged in the stop switch SW2, a red LED on the top of each key SW3 lighting.

然后,判断停止开关SW2或SW3中的任意一个是否被按动(步骤S244), 在被按动了时,停止蜂鸣器鸣叫(步骤S246)。 Then, it is determined arbitrarily stop switch SW2 or SW3 is pressed whether one (step S244), when pressed, the buzzer is stopped (step S246). 随后,将定时器的时间T回零(步骤S248),并判断是否有其他开关SW的操作(步骤S250)。 Subsequently, the timer time T back to zero (step S248), and determines whether there are other operation switch SW (step S250). 当在自停止蜂鸣器鸣叫后的20秒钟期间没有其他开关SW的操作时(步骤S252), 进入步骤S230,并进行减压动作,直到达到负压压力Ps为止。 When during 20 seconds from stopping the buzzer after the other switch SW is not operated (step S252), enters the step S230, the operation and under reduced pressure, until the negative pressure until the pressure Ps.

另一方面,在骤S244中,在停止开关SW2或SW3没有被按动时,判断蜂鸣器鸣叫的时间T是否经过了20秒钟(步骤S254),若经过了20秒钟, 则在自动地停止蜂鸣器鸣叫以后(步骤S256),进入步骤230,并进行减压动作直到减压到负压压力P3为止。 On the other hand, in step S244, the stop switch SW2 or SW3, when not pressed, the buzzer is determined whether the elapsed time T of 20 seconds (step S254), if after 20 seconds, the automatic after stopping the buzzer (step S256), proceeds to step 230, and negative pressure operation until a reduced pressure up to P3.

以下,说明气囊220破裂时的异常检测。 Hereinafter, the airbag 220 when the abnormality detection rupture.

由于沿气囊式内窥镜210的插入部212所设的空气供给管的直径、比管子310的直径小,(管子310的直径约为6mm,空气供给管的直径约为0.8mm),当开始供给空气(加压)时,在气囊220的压力达到加压压力P! Since the diameter of the air supply pipe along the balloon of the endoscope insertion portion 212 of the set 210, 310 smaller than the diameter of the tube, (the diameter of the tube 310 is about 6mm, the diameter of the air supply tube is about 0.8mm), when the start when the supply air (pressure), the pressure in the airbag 220 has reached the pressing pressure P! 之前,管子310内的压力先达到加压压力Pi,并停止加压动作。 Previously, the pressure in the tube 310 reaches the first pressing pressure Pi, and the pressurizing operation is stopped. 但是,当气 However, when gas

22囊220的压力没有达到加压压力Pi时,由于管子310内的空气通过空气供 22 bladder 220 pressure does not reach the pressing pressure Pi, the air in the air supply tubes 310

给管向气囊220供给,所以管子310内的压力会再次降低,并变得比加压压力P!小。 The airbag 220 is supplied to the tube, the pressure within the tube 310 will be lowered again, and becomes! Smaller than the pressing pressure P. 这时,序列发生器370,根据来自压力传感器SA1的检测信号再次开始加压动作。 In this case, sequencer 370, based on the detection signal from the pressure sensor SA1 to start the compression operation again.

在气囊220没有破裂时,多次地重复上述加压动作的开始与停止,则可使气囊220的压力达到加压压力P,,但是当气囊220破裂时,即使长时间重复加压动作也不能使气囊220的压力达到加压压力&。 Not broken when the airbag 220, a plurality of times repeatedly start and stop the pressurizing operation, the pressure of the airbag 220 can reach the pressing pressure P ,, but broken when the airbag 220 even if the pressing operation is repeated for a long time can not be the balloon pressure reaches 220 & pressurized pressure.

这时,在本实施例中,以短周期重复加压动作的开始及停止(即,电磁阀VA1的通/断振荡),但在持续了比收縮正常的气囊220的加压动作时产生的振荡期间充分长的时间(例如,40秒钟)时,则判断为气囊220破裂, 并且蜂鸣器鸣叫。 Generated during this time, in the present embodiment, in order to short-period repeats start and stop the pressurizing operation (i.e., electromagnetic valve VA1 on / off oscillation), but continued normal operation of a pressurized bladder contraction than 220 oscillation period sufficiently long time (e.g., 40 seconds), it is determined that the airbag 220 ruptured, and the buzzer sounds.

以下,参照图13的流程图说明暂停处理。 Hereinafter, with reference to the flowchart of FIG. 13 described hold.

序列发生器370,判断保持气囊220的压力的暂停指令的输入(暂停开关SW5的接通)是在减压动作中、还是加压动作中(步骤S302)。 Input sequence generator 370, it is determined to maintain the pressure of the airbag 220 of the pause command (STOP switch SW5 is turned on) is reduced in the operation, or pressurization operation (step S302). 并且, 当在减压动作中输入了暂停指令时,使电磁阀VA2的螺线管动作,将电磁阀VA2切换于位置a,并停止减压动作(步骤S304)。 And, when the pressure input operation in the suspend instruction, the operation of the solenoid of the solenoid valve VA2, the electromagnetic valve VA2 is switched to the position a, and stop the pressure reduction operation (step S304).

另一方面,当在加压动作中输入了暂停指令时,使电磁阀VA1的螺线管动作,将电磁阀VAl切换于位置a,并停止加压动作(步骤S306)。 On the other hand, when the pause command is input in operation pressure, the operation of the solenoid of the solenoid valve VA1, the solenoid valve is switched to the position VAl a, and stops the pressurization operation (step S306).

该暂停功能,例如,在一边使气囊膨胀一边将双气囊式内窥镜插入在大肠内时使用。 The pause function, for example, while the balloon is inflated at the side of the double-balloon-type endoscope is inserted in large intestine. 即,在与小肠相比肠管直径大的大肠中,气囊的大小达到了管腔,可是有时气囊的压力还未上升到预先设定的加压压力P!,这时使用上述暂停功能并停止加压动作。 That is, in the large intestine and small intestine as compared to the diameter of the bowel, the size of the airbag is brought to the lumen, but the pressure of the airbag may not yet risen to a predetermined applied pressure P !, case using the pause and stop functions added pressure action.

另外,在操作双气囊式内窥镜时,通常,由于观察透视图像,所以可根据该透视图像判断气囊在大肠内是否充分地膨胀了。 Further, when the double-balloon endoscope operation, generally, since the viewing perspective image, based on the fluoroscopic image can be determined whether the airbag is sufficiently inflated in the large intestine in the.

另外,当在减压动作或加压动作中的暂时停止中, 一旦再次按动开关SW5,则恢复暂时停止前的减压动作或加压动作。 Further, when the operation is temporarily stopped at a reduced pressure or pressurization operation, the switch SW5 is pressed once again, the recovery operation under reduced pressure or pressurization is temporarily stopped before the operation. 并且,在减压动作或加压动作的暂时停止中, 一旦按动了加压或减压开关(内窥镜通/断开关SW4), 则根据所按动的开关,优先动作。 Further, the operation is temporarily stopped or reduced pressure operation, upon pressing a pressurization or depressurization switch (endoscope on / off switch SW4 is), then press the switch according to the priority operation.

在该实施例中,是在内窥镜用控制系统A及套管用控制系统B中,分 In this embodiment, in the endoscope control system A and the casing B control system, points
