技术领域technical field

本发明涉及ICU重症医疗技术领域。The invention relates to the technical field of ICU intensive care medicine.

背景技术Background technique

现有的ICU护理中，在术中或术后常需要对患者存在积液处进行引流护理，而一般的引流装置利用负压和引流管进行引流操作，但是在体内引流时，引流管端部进口的堵塞问题始终无法很好的解决，一般的解决方案通过增加过滤装置防止堵塞，但是不能从根本上解决问题，过滤装置仍需要更换甚至使用中会出现自身完全堵塞无法正常工作的问题。而在积液引流中，一般的堵塞物为凝结块或粘稠物等，被吸入到端部内容易造成堵塞，因此需要能够对其进行有效处理，以防止堵塞，保证引流高效进行。同时，一般的引流管不能够很好的进行端部的封堵，带来很多问题，防止引流管内积液倒流时，无法从进口端部进行封堵，则引流管内积液易倒流。In the existing ICU care, it is often necessary to perform drainage care for the patient with fluid accumulation during or after surgery, while the general drainage device uses negative pressure and drainage tube for drainage operation. The problem of clogging of the inlet can not be solved well. The general solution is to add a filter device to prevent clogging, but it cannot solve the problem fundamentally. The filter device still needs to be replaced and even the problem of self-clogging and unable to work normally occurs during use. In effusion drainage, the common blockages are clots or viscous substances, which are easily sucked into the end to cause blockages. Therefore, it is necessary to effectively treat them to prevent blockages and ensure efficient drainage. At the same time, the general drainage tube cannot be well sealed at the end, which brings many problems. When preventing the backflow of fluid in the drainage tube, it cannot be blocked from the inlet end, and the fluid in the drainage tube is easy to backflow.

本发明有益效果在于：The beneficial effects of the present invention are:

1、脉冲负压装置和防堵装置配合，利用气压的控制，有效实现引流端部进口的防堵，避免引流液中凝结块的堵塞，有助于高效快速的实现引流，能够方便的实现端部的封口，避免倒流。1. The pulse negative pressure device and the anti-blocking device cooperate to use the air pressure control to effectively achieve the anti-blocking of the inlet of the drainage end, avoid the blockage of the clot in the drainage liquid, help to achieve efficient and rapid drainage, and can easily realize the end of the drainage. Part of the seal to avoid backflow.

脉冲负压装置可实现脉冲式抽气，使收集箱内部的负压值快速波动，收集箱内负压变小(气压升高)和增大(气压下降)的同时，即可使控制气囊压缩或膨胀，控制气囊与弹性气囊直接连通交换气体，从而控制弹性气囊膨胀或缩小，在管头端部内，弹性气囊的膨胀或缩小可控制改变引流端口的直径变化，避免堵塞，同时在高频波动下，弹性气囊快速的进行内口直径的变化，能够对不易引流的凝结块等进行敲击式挤压压缩，缩小凝结块直径甚至破碎，粘稠物也可被拉扯分离，方便于进行快速的引流。通过气压传感器模块可检测判断控制脉冲负压装置的开启和关闭等。The pulse negative pressure device can realize pulsed air extraction, so that the negative pressure value inside the collection box fluctuates rapidly. When the negative pressure in the collection box decreases (the air pressure increases) and increases (the air pressure decreases), the control airbag can be compressed. Or inflate, control the air bag and the elastic air bag to directly communicate to exchange gas, so as to control the expansion or contraction of the elastic air bag. In the end of the tube head, the expansion or contraction of the elastic air bag can control the change of the diameter of the drainage port, avoid blockage, and at the same time fluctuate in high frequency The elastic airbag can quickly change the diameter of the inner opening, and can perform percussion extrusion compression on the clot that is not easy to drain, reduce the diameter of the clot or even break it, and the viscous material can also be pulled and separated, which is convenient for rapid drainage. The opening and closing of the pulse negative pressure device can be detected and judged through the air pressure sensor module.

通过负压泵和控制气囊的配合，可简化动力结构，利用负压引流的负压泵进行整个动力的同步控制，且负压的变化与引流进口直径的变化相配合，可提高引流效果，当收集箱内部负压变大时，弹性气囊缩小，进口直径变大，此时更容易抽取大体积的凝结块或粘稠的积液等，避免堵塞。同时，变化的抽液负压，也有利于提高抽取不易流动的积液的作用。Through the cooperation of the negative pressure pump and the control airbag, the power structure can be simplified. The negative pressure pump for negative pressure drainage is used to control the entire power synchronously, and the change of the negative pressure is matched with the change of the diameter of the drainage inlet, which can improve the drainage effect. When the negative pressure inside the collection box increases, the elastic air bag shrinks and the diameter of the inlet becomes larger. At this time, it is easier to extract a large volume of coagulation or viscous effusion to avoid blockage. At the same time, the changing negative pressure of liquid extraction is also beneficial to improve the effect of extracting fluid that is not easy to flow.

注射器与弹性气囊连通，可实现补充加压，使弹性气囊能够膨胀至封堵状态，对管头的端部实现封堵，从端部进行封堵，可避免引流管内的液体倒流，防倒流效果更好。在控制气囊控制弹性气囊变化时，注射器可起到幅度调节作用，在稳定状态下，注射器可控制调节进口直径；The syringe is connected with the elastic air bag, which can realize supplementary pressure, so that the elastic air bag can be inflated to a blocked state, and the end of the tube head can be blocked. better. When the airbag is controlled to control the change of the elastic airbag, the syringe can play a role of amplitude adjustment, and in a stable state, the syringe can control and adjust the diameter of the inlet;

2、通过气压传感器模块检测收集箱内部的气压判断是否发生了端部堵塞，并通过处理器进行控制工作，同时可通过指示灯的闪烁等进行工作状态提示；2. The air pressure inside the collection box is detected by the air pressure sensor module to determine whether the end blockage has occurred, and the processor is used to control the work. At the same time, the working status can be prompted by the flashing of the indicator light;

3、管头表面与抽取部位进行接触，涂覆血液抗凝剂，可在进行血液抽取引流时，防止抽取部位血液凝固，有利于液体抽取的进行；3. The surface of the tube head is in contact with the extraction site and is coated with blood anticoagulant, which can prevent blood coagulation at the extraction site during blood extraction and drainage, which is beneficial to the liquid extraction;

4、弹性气囊覆盖管头的左端时，弹性气囊膨胀可形成端部的弧面，有利于整体进入到抽取部位；4. When the elastic airbag covers the left end of the tube head, the expansion of the elastic airbag can form an arc surface at the end, which is conducive to the overall access to the extraction site;

5、弹性气囊内设置弹性拉力线，可辅助实现弹性气囊的回缩，同时可起到一定的定型作用；5. The elastic tension line is set in the elastic air bag, which can assist in the retraction of the elastic air bag, and can also play a certain role in shaping;

6、稳压阀的设置可避免收集箱内负压过大，当负压超过预设值时，可与外界直接连通，避免造成伤害。6. The setting of the pressure-stabilizing valve can avoid excessive negative pressure in the collection box. When the negative pressure exceeds the preset value, it can be directly connected to the outside world to avoid damage.

如图1-6所示，一种ICU护理用快速引流装置，包括收集箱1；收集箱1上端连通有引流管2；引流管2上安装有防堵装置；收集箱1上端安装有脉冲负压装置；所述的防堵装置包括与引流管2顶端连通的管头3；管头3内左部套接固定安装有环形的弹性气囊4；弹性气囊4连通有导气管5；导气管5在引流管2内，且延伸至收集箱1内；在收集箱1内，导气管5末端连通有控制气囊6；导气管5中部连通有支管7；支管7密封穿过引流管2的中部，支管7另一端与一个注射器8的端口连通；所述的脉冲负压装置包括安装在收集箱1上端的负压泵9；负压泵9的抽气端连通有三通管10；三通管10的左端端口与负压泵9抽气端连通，右端端口连通有抽气管11，前端端口固定连通有密封气囊12；抽气管11与收集箱1密封连通；在密封气囊12前侧，收集箱1上端安装有驱动电机13；驱动电机13的输出端安装有凸轮14，凸轮14侧面与密封气囊12前端面接触；收集箱1内顶端安装有气压传感器模块15；气压传感器模块15的信号输出端与一个处理器连接；处理器的输出端与负压泵9和驱动电机13的控制电路电连接；收集箱1上端安装有指示灯16；处理器的输出端与指示灯16的控制电路电连接；管头3的表面涂覆有血液抗凝剂；弹性气囊4覆盖管头3的左端面；弹性气囊4内设置有弹性拉力线17；收集箱1的顶端壁内安装有稳压阀18。As shown in Figures 1-6, a rapid drainage device for ICU nursing includes a collection box 1; a drainage tube 2 is connected to the upper end of the collection box 1; an anti-blocking device is installed on the drainage tube 2; The anti-blocking device includes a pipe head 3 that communicates with the top of the drainage pipe 2; the inner left part of the pipe head 3 is sleeved and fixedly installed with an annular elastic air bag 4; In the drainage tube 2, and extend into the collection box 1; in the collection box 1, the end of the air conduit 5 is connected with a control balloon 6; the middle of the air conduit 5 is connected with a branch pipe 7; The other end of the branch pipe 7 is communicated with the port of a syringe 8; the pulse negative pressure device comprises a negative pressure pump 9 installed on the upper end of the collection box 1; the suction end of the negative pressure pump 9 is communicated with a tee pipe 10; the tee pipe 10 The left end port is communicated with the suction end of the negative pressure pump 9, the right end port is communicated with a suction pipe 11, and the front end port is fixedly connected with a sealing air bag 12; the air suction pipe 11 is in sealing communication with the collection box 1; A drive motor 13 is installed at the upper end; a cam 14 is installed at the output end of the drive motor 13, and the side of the cam 14 is in contact with the front end surface of the sealing airbag 12; the top end of the collection box 1 is installed with an air pressure sensor module 15; A processor is connected; the output end of the processor is electrically connected with the control circuit of the negative pressure pump 9 and the drive motor 13; the upper end of the collection box 1 is provided with an indicator light 16; the output end of the processor is electrically connected with the control circuit of the indicator light 16; The surface of the tube head 3 is coated with blood anticoagulant; the elastic air bag 4 covers the left end surface of the tube head 3 ; the elastic air bag 4 is provided with an elastic tension wire 17 ;

本发明在使用时，将引流管2及管头3插入到患者积液的部位，在外部进行粘接固定，开启负压泵9，负压泵9使收集箱1内部形成负压状态，利用负压抽取积液。负压泵9稳定工作，且积液抽取处于稳定状态时，收集箱1内的负压状态同样较为稳定。环形弹性气囊4的中间部位为引流进口。当引流进口被凝结块等堵塞时，造成积液抽取的阻碍，则收集箱1内部负压升高，气压传感器模块15可检测到气压的短时持续下降，此时处理器判断为引流进口被堵塞，处理器控制驱动电机13工作，实现脉冲式负压工作，避免堵塞。When the present invention is in use, thedrainage tube 2 and thetube head 3 are inserted into the site of the patient's fluid accumulation, adhered and fixed externally, thenegative pressure pump 9 is turned on, and thenegative pressure pump 9 forms a negative pressure state inside thecollection box 1, Negative pressure extraction of effusion. When thenegative pressure pump 9 works stably, and the fluid extraction is in a stable state, the negative pressure state in thecollection tank 1 is also relatively stable. The middle part of the annularelastic airbag 4 is the drainage inlet. When the drainage inlet is blocked by clots, etc., which will hinder the extraction of accumulated fluid, the negative pressure inside thecollection box 1 will increase, and the airpressure sensor module 15 can detect a short-term continuous drop in air pressure. At this time, the processor determines that the drainage inlet is blocked. Blockage, the processor controls thedrive motor 13 to work, realizes pulsed negative pressure work, and avoids blockage.

如图2-4所示，在脉冲式负压工作状态下，处理器控制驱动电机13启动，带动凸轮14转动，快速的反复挤压释放密封气囊12，挤压密封气囊12时，相当于密封容积缩小，收集箱1内部负压下降，气压升高，则控制气囊6被压缩，控制气囊6直接与弹性气囊4连通，弹性气囊4随之膨胀，则进口直径缩小，此时，弹性气囊4将对堵塞在端部进口处的凝结块等进行挤压压缩，之后很快密封气囊12被释放，在密封气囊12自身伸缩弹性的作用下膨胀吸气，相当于密封容积变大，收集箱1内部气压降低，负压增强，吸力增强，控制气囊6内部气压大于外部，控制气囊6膨胀，将弹性气囊4内的气体抽入到控制气囊6内，弹性气囊4缩小，进口直径扩大，此时在负压增大抽取力的作用下以及进口的扩大，堵塞的凝结块等则非常容易的进入到引流管2内，且进入的凝结块等经过挤压压缩，直径小于引流管2直径。若经过一次的挤压压缩，凝结块仍堵塞在进口处，在处理器控制下，驱动安电机快速动作，则弹性气囊4快速的进行多次的膨胀与缩小，则能够使凝结块直径缩小甚至破碎，最后被负压抽取，恢复至稳定的工作状态。As shown in Figure 2-4, in the pulsed negative pressure working state, the processor controls thedrive motor 13 to start, drives thecam 14 to rotate, and quickly and repeatedly squeezes and releases the sealingairbag 12. When the sealingairbag 12 is squeezed, it is equivalent to sealing When the volume shrinks, the negative pressure inside thecollection box 1 drops and the air pressure rises, thecontrol airbag 6 is compressed, thecontrol airbag 6 is directly connected with theelastic airbag 4, and theelastic airbag 4 expands accordingly, and the diameter of the inlet is reduced. At this time, theelastic airbag 4 It will squeeze and compress the clotted block at the inlet of the end, and then theairbag 12 will be released soon, and theairbag 12 will expand and inhale under the action of the elastic elasticity of theairbag 12 itself, which is equivalent to the increase of the sealing volume, and thecollection box 1 The internal air pressure decreases, the negative pressure increases, the suction force increases, the internal air pressure of thecontrol airbag 6 is greater than the external air pressure, thecontrol airbag 6 expands, and the gas in theelastic airbag 4 is drawn into thecontrol airbag 6, theelastic airbag 4 shrinks, and the inlet diameter expands. Under the action of the negative pressure increasing the extraction force and the expansion of the inlet, the blocked clots can easily enter thedrainage tube 2 , and the entering clots are squeezed and compressed, and the diameter is smaller than the diameter of thedrainage tube 2 . If the coagulation block is still blocked at the inlet after one squeeze and compression, under the control of the processor, the motor is driven to move quickly, and theelastic airbag 4 rapidly expands and shrinks many times, which can reduce the diameter of the coagulation block or even reduce it. Broken, and finally extracted by negative pressure, it returns to a stable working state.

脉冲式负压工作状态，可由定时器模块进行控制，或手动控制，一次开启后工作一小段时间，比如五秒等，因高频动作，不需要太长的时间，即便一个工作周期内未解决，负压上升会马上开启下一个工作周期。在管头3中，弹性气囊4的体积较小，能够进行快速的调节。The pulsed negative pressure working state can be controlled by the timer module, or manually controlled. After one turn on, it will work for a short period of time, such as five seconds. Due to high-frequency action, it does not take too long, even if it is not resolved within a working cycle. , the rise of negative pressure will immediately start the next working cycle. In thetube head 3, the volume of theelastic air bag 4 is small, which enables quick adjustment.

在进入脉冲式负压工作状态下时，处理器也可以首先控制负压泵9提高工作的功率，在相对较大的负压状态下进行脉冲调节(该负压处于安全负压内)，增大吸力。When entering the pulsed negative pressure working state, the processor can also firstly control thenegative pressure pump 9 to increase the working power, and perform pulse adjustment in a relatively large negative pressure state (the negative pressure is within the safe negative pressure), increasing the Great suction.

如图3-5所示，注射器8可通过支管7和导气管5向弹性气囊4和控制气囊6内加压注气，改变基础的气体量，最终使弹性气囊4形成的进口直径受注射器8的调节控制。在管头3进入人体时，可通过注射器8使弹性气囊4膨胀至最大状态，将管头3的端部封闭，则在穿过人体进入时，可避免管头3的端部插入一些物质或组织等造成堵塞；若弹性气囊4将管头3的左端包裹时，则膨胀状态下形成弧面，能够减少进入人体狭窄地方的阻力；当积液抽取完成或中止时，通过注射器8使弹性气囊4膨胀封堵管头3的端部，可避免溢流管内的积液倒流。As shown in Figures 3-5, thesyringe 8 can pressurize and inject gas into theelastic airbag 4 and thecontrol airbag 6 through the branch pipe 7 and theairway 5 to change the basic gas volume, and finally make the diameter of the inlet formed by theelastic airbag 4 be affected by thesyringe 8. adjustment control. When thetube head 3 enters the human body, theelastic airbag 4 can be inflated to the maximum state through thesyringe 8, and the end of thetube head 3 is closed, so that when entering through the human body, the end of thetube head 3 can be prevented from inserting some substances or If theelastic air bag 4 wraps the left end of thetube head 3, an arc surface will be formed in the expanded state, which can reduce the resistance of entering the narrow place of the human body; 4. The end of thepipe head 3 is expanded and blocked to avoid the backflow of the accumulated liquid in the overflow pipe.

可通过常规的固定安装结构和导向结构，辅助定位密封气囊12，以保证凸轮14作用于密封气囊12时发生定向的伸缩形变。The conventional fixed installation structure and guide structure can be used to assist the positioning of the sealingairbag 12 to ensure that the directional telescopic deformation occurs when thecam 14 acts on the sealingairbag 12 .
