本实用新型涉属于医疗器械技术领域，具体涉及一种双腔球囊子宫造影通水管。The utility model belongs to the technical field of medical equipment, in particular to a double-cavity balloon hysterography water conduit.
背景技术Background technique
近年来，育龄妇女不孕逐年增加，其中输卵管阻塞因素为最主要的病因，特别是在继发性不孕症中比例可高达66.67％。输卵管通畅检查方法很多，包括影像学检查、输卵管通液及输卵管镜腹腔镜检查，影像学检查包括子宫输卵管造影、子宫输卵管超声造影等。输卵管通液简便易行，但存在较大的盲目性和不准确性，目前作为一种初筛手段。腹腔镜直视下输卵管通液检查目前被认为是最可靠的检查方法，但由于腹腔镜检查的有创性和价格昂贵，目前更倾向于作为治疗手段。近年来发展的子宫输卵管超声造影亦是根据加压充盈宫腔造影，但超声图像对于临床医生来说比较抽像不易理解。而传统子宫输卵管造影(Hysterosalpingography，HSG)可显示宫腔和输卵管形态、对比剂充盈和通畅情况，图像一目了然，目前仍是诊断输卵管阻塞性不孕的首选检查方法以及金标准。但由于这种检查方法是在X线下操作，对医生、患者均有辐射损伤。In recent years, the infertility of women of childbearing age has been increasing year by year, among which tubal obstruction is the main cause, especially in secondary infertility, the proportion can be as high as 66.67%. There are many ways to check the patency of fallopian tubes, including imaging examination, tubal fluid and salpingoscopic laparoscopy, and imaging examinations include hysterosalpingography, hysterosalpingography and so on. Tubal fluid is simple and easy to do, but there are large blindness and inaccuracy, and it is currently used as a primary screening method. Laparoscopic tubal fluid examination under direct vision is currently considered the most reliable examination method, but due to the invasiveness and high price of laparoscopy, it is more inclined to be used as a treatment method at present. The hysterosalpingo-enhanced ultrasonography developed in recent years is also based on pressurized filling hysterography, but the ultrasonic images are more abstract and difficult to understand for clinicians. The traditional hysterosalpingography (Hysterosalpingography, HSG) can show the shape of the uterine cavity and fallopian tubes, and the filling and patency of the contrast agent. However, since this inspection method is operated under X-rays, there is radiation damage to doctors and patients.
目前子宫造影管所用的单球囊无注药控制阀硅胶造影管，包括软管，软管中设有管芯，软管端部设有两个分支管，在软管中设有两个通道，分别延伸至分支管中，所述的两个通道设置在管芯中，其中一个通道设置有通至软管外的出液孔，另一通道通至软管外壁设置的包绕软管主体的球囊。使用时，首先将软管主体的头端置入宫颈中，当球囊进入子宫腔后，通过充气口向球囊充气，球囊扩张后因其直径大于宫颈管而不会脱出，然后再通过注液管向宫腔内注入药物进行检查。所存在的问题是：对于宫腔小的患者，注药时因压力增大而将造影管头端弯曲，导致堵塞输卵管间质部，使得同侧输卵管不显影造成假阳性；同时由于没有控制阀，注射药物后医生不能离开操作室，无形中增加了医生和患者受辐射的风险。At present, the single balloon non-injection control valve silicone contrast tube used in the hysterography tube includes a hose with a core in the hose, two branch tubes at the end of the hose, and two channels in the hose. , respectively extending into the branch pipes, the two passages are arranged in the tube core, one of which is provided with a liquid outlet leading to the outside of the hose, and the other passage is connected to the surrounding hose body provided on the outer wall of the hose of the balloon. When in use, first put the head end of the main body of the hose into the cervix. When the balloon enters the uterine cavity, inflate the balloon through the inflation port. The injection tube injects drugs into the uterine cavity for inspection. The existing problems are: for patients with a small uterine cavity, the head end of the contrast tube will be bent due to the increase of pressure during the injection, resulting in blocking the interstitial part of the fallopian tube, so that the ipsilateral fallopian tube will not be developed and cause false positives; at the same time, because there is no control valve , Doctors cannot leave the operating room after injecting drugs, which virtually increases the risk of radiation exposure to doctors and patients.
目前市场上的双球囊造影管均为三腔管，注药、双球囊为单独腔道，采用硬质塑料材料，这种造影管价格较高，造形复杂，操作过程中如遇紧急情况，医生可能会搞混将药注入球囊引起球囊破裂，尤其是宫腔内球囊如果破裂，必须重新换新管。尽管双球囊、单球囊均采用“苹果”形状，由于宫颈管长度有个体差异，如果球囊位于宫颈管内注气时会引起剧痛，未产妇甚至会引起疼痛性休克。At present, the double-balloon imaging tubes on the market are all three-lumen tubes. The drug injection and double-balloon are separate lumens, which are made of hard plastic materials. This type of imaging tube is expensive and complicated in shape. , the doctor may confuse the medicine into the balloon and cause the balloon to rupture, especially if the intrauterine balloon ruptures, it must be replaced with a new tube. Although both the double balloon and the single balloon are in the shape of an "apple", due to individual differences in the length of the cervical canal, if the balloon is placed in the endocervical canal, it will cause severe pain when inflated, and nulliparous women may even cause painful shock.

具体实施方式detailed description
下面结合附图与具体实施方式对本实用新型作出进一步详细描述。The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
如图1所示，本实用新型提供了一种双腔子宫造影通水管，包括主管1和设置在主管后端的注液连接管2和充气连接管3，在主管中设有相互隔离的主腔通道4和球囊腔通道5，其中主腔通道4与注液连接管2相连通，球囊腔通道5与充气连接管3相连通，在主管1的前端设有与球囊腔通道5相连通的球囊；位于主管1前端的主腔通道4上成型一具有防倒流开孔的出液口8，当主腔通道4中的注液压力大于宫腔压力时，防倒流开孔打开，主腔通道4中的注液流出。通过在主腔通道4上的前端设置一出液口8，只有当注射至主腔通道4中的压力大于宫腔压力时，才能使防倒流开孔打开，将注液推入宫腔中；在停止注药后，防倒流开孔会处于闭合状态，从而避免了宫腔内的药物发生逆流，注射后的医生可以离开操作室，避免医生受辐射的风险。主管1、注液连接管2和充气连接管3优选采用硅胶材料制成。As shown in Figure 1, the utility model provides a double-cavity hysterography water pipe, which includes a main pipe 1, a liquid injection connecting pipe 2 and an inflation connecting pipe 3 arranged at the rear end of the main pipe, and the main chamber is provided with mutually isolated main chambers. Channel 4 and balloon cavity channel 5, wherein the main cavity channel 4 communicates with the injection connecting tube 2, the balloon cavity channel 5 communicates with the inflation connecting tube 3, and the front end of the main tube 1 is provided with the balloon cavity channel 5. The balloon is connected; a liquid outlet 8 with an anti-backflow opening is formed on the main cavity channel 4 at the front end of the main tube 1. When the injection pressure in the main cavity channel 4 is greater than the pressure in the uterine cavity, the anti-backflow opening is opened and the main cavity The infusion fluid in chamber channel 4 flows out. By setting a liquid outlet 8 at the front end of the main cavity channel 4, only when the pressure injected into the main cavity channel 4 is greater than the pressure of the uterine cavity, the anti-backflow opening can be opened, and the injection liquid can be pushed into the uterine cavity; After stopping the injection, the anti-backflow opening will be in a closed state, thereby avoiding the backflow of the medicine in the uterine cavity, and the doctor after the injection can leave the operating room to avoid the risk of radiation exposure to the doctor. The main pipe 1, the liquid injection connecting pipe 2 and the inflation connecting pipe 3 are preferably made of silica gel.
图2所示为本实用新型提供的十字形防倒流开孔，图示结构正处于开启状态。Figure 2 shows the cross-shaped anti-backflow opening provided by the utility model, and the structure shown in the figure is in an open state.
图3是本实用新型提供的一字形孔结构，图示结构正处于闭合状态，当向主腔通道4中注入药液时，由于主管采用柔性材料制成，在注液压力的作用下，防倒流开孔会形成一个一字形的缝隙，药液会从此缝隙中流出；停止注药时，一字形缝隙闭合，防止宫腔中的药液回流至主腔通道内。Fig. 3 is the inline hole structure provided by the utility model, and the structure shown in the figure is in a closed state. When the liquid medicine is injected into the main cavity channel 4, since the main tube is made of flexible material, under the action of the liquid injection pressure, the anti- The backflow opening will form a straight gap from which the liquid medicine will flow out; when the drug injection is stopped, the straight gap will be closed to prevent the liquid medicine in the uterine cavity from flowing back into the main cavity channel.
图4和图5是本实用新型所提供的Y形孔和T形孔，当然不限于本实用新型所提供上述防倒流开孔结构，也可以为其它形状的开孔，比如半圆弧形等等，这里就不再赘述。Figure 4 and Figure 5 are Y-shaped holes and T-shaped holes provided by the utility model, of course, they are not limited to the above-mentioned anti-backflow opening structure provided by the utility model, and can also be openings of other shapes, such as semi-circular arcs, etc. , which will not be repeated here.

还可以在主腔通道4的腔壁上设置多个出液口8，其沿主管1的前端周向呈等间距布置。A plurality of liquid outlets 8 may also be provided on the cavity wall of the main cavity channel 4 , which are arranged at equal intervals along the circumferential direction of the front end of the main tube 1 .
为了避免球囊漏气，本实用新型优选在充气连接管3上设置一个夹紧装置9，当向球囊腔通道中注满气体后，通过夹紧装置9将充气连接管3夹住，防止气体在充气端发生泄气现象。本实用新型中还同时在注液连接管上设置一同样的夹紧装置9，对于防止宫腔内的药液回流起到双保险作用。In order to avoid air leakage of the balloon, the utility model preferably arranges a clamping device 9 on the inflatable connecting tube 3. After filling the balloon cavity channel with gas, the inflating connecting tube 3 is clamped by the clamping device 9 to prevent The gas is deflated at the inflation end. In the utility model, a same clamping device 9 is also set on the liquid injection connecting pipe at the same time, which plays a double insurance role for preventing the backflow of the medicinal liquid in the uterine cavity.
具体地，在没去掉注射器之前，充气连接管和注液连接管仍处于密封状态，采用夹紧装置夹住充气连接管和注液连接管，再次密闭充气连接管和注液连接管，然后再去掉注射器，从而避免了充气连接管漏气和注液连接管中的药液回流。Specifically, before the syringe is removed, the inflation connecting tube and the liquid injection connecting tube are still in a sealed state, and a clamping device is used to clamp the inflation connecting tube and the liquid injection connecting tube, and the inflation connecting tube and the liquid injection connecting tube are sealed again, and then Remove the syringe, thereby avoiding the air leakage of the inflation connection tube and the backflow of the liquid medicine in the injection connection tube.
其中的夹紧装置为一控制阀，通过控制阀门开启可以对球囊进行泄压，取出宫腔内的球囊，操作方便。这里的控制阀为现有技术，这里就不再对此详细描述。The clamping device is a control valve, and the pressure of the balloon can be released by opening the control valve, and the balloon in the uterine cavity can be taken out, and the operation is convenient. The control valve here is a prior art, so it will not be described in detail here.
为了防止位于宫腔内球囊的迅速扩张，避免对患者造成痛苦，其中的球囊包括气流连通的第一球囊6和第二球囊7，第一球囊6和第二球囊7沿着主管1长度方向呈前后间隔设置。其中的第一球囊6靠近出液口，在进行宫腔检查或治疗时第一球囊6位于宫腔内，而第二球囊7位于宫颈外，两球囊之间的位置属于卡位固定位置，可起到很好的固定作用；在对两球囊注气时，由于宫腔压力作用，位于宫颈外部的第二球囊会先行注气，由于双球囊内部联通，位于宫腔内的球囊会逐渐充入气体，使其逐渐扩张，操作人员可以通过观察位于宫颈外部的球囊的充气状态，对位于宫腔内的球囊充气状态作出准确判断，大大减缓了注气时宫腔内球囊的扩张速度，可以避免因第一球囊压力急骤增大产生撕裂宫颈所引起的患者剧痛，同时由于两球囊采用弧形过渡结构，形成弧形的卡位部，适合宫颈解剖形态，球囊扩张时很好地与宫颈壁相贴合，有利治疗。In order to prevent the rapid expansion of the balloon located in the uterine cavity and avoid causing pain to the patient, the balloon includes a first balloon 6 and a second balloon 7 in airflow communication, and the first balloon 6 and the second balloon 7 are arranged along the The longitudinal direction of the main pipe 1 is arranged at intervals front and back. The first balloon 6 is close to the liquid outlet, and the first balloon 6 is located in the uterine cavity during uterine examination or treatment, while the second balloon 7 is located outside the cervix, and the position between the two balloons is a stuck position The fixed position can play a very good role in fixing; when the two balloons are inflated, due to the pressure of the uterine cavity, the second balloon located outside the cervix will be inflated first. The balloon inside will be gradually inflated with gas to make it expand gradually. The operator can make an accurate judgment on the inflation state of the balloon in the uterine cavity by observing the inflation state of the balloon outside the cervix, which greatly slows down the time of gas injection. The expansion speed of the intrauterine balloon can avoid the severe pain caused by the tearing of the cervix due to the sudden increase in the pressure of the first balloon. At the same time, because the two balloons adopt a curved transition structure, an curved locking part is formed , suitable for the anatomical shape of the cervix, when the balloon is inflated, it fits well with the cervix wall, which is favorable for treatment.
其中的第一球囊6和第二球囊7之间的卡位部长度为4-6cm，本实用新型优选5cm。充气后的第一球囊6形成形结构，第二球囊7形成形结构，二者气流导通后形成形结构，如图1所示。Wherein the length of the engaging portion between the first balloon 6 and the second balloon 7 is 4-6cm, preferably 5cm in the present invention. The inflated first balloon 6 forms shaped structure, the second balloon 7 forms Shaped structure, the air flow between the two forms shape structure, as shown in Figure 1.
为了便于球囊注气和对主腔通道注液，在注液连接管2和充气连接管3上分别连接一注射器接头10，注射器接头10设置在控制阀的后端位置。In order to facilitate balloon injection and liquid injection to the main lumen channel, a syringe joint 10 is respectively connected to the liquid injection connecting pipe 2 and the inflation connecting pipe 3, and the syringe joint 10 is arranged at the rear end of the control valve.
本实用新型通过防倒流开孔、双球囊、夹紧装置的联合使用，使得注药后医生可以离开操作室进行摄片，避免医生不必要的辐射，而患者也无需在透视下进行观察，可以直接进行摄片，减少辐射剂量，同时药物不会返流入造影管影响成像质量，亦可以有压力存在对轻度粘连的输卵管仍有冲击力达到再通目的；所提供结构具有成本低廉，操作简单，使用方便，可控性强，有助于提高诊断准确率，便于在行业内推广应用。The utility model uses anti-backflow openings, double balloons, and clamping devices in combination, so that the doctor can leave the operating room to take pictures after injection, avoiding unnecessary radiation for the doctor, and the patient does not need to observe under fluoroscopy. It can be taken directly to reduce the radiation dose, and at the same time, the drug will not flow back into the contrast tube to affect the imaging quality, and there can be pressure to still have an impact on the mildly adhered fallopian tubes to achieve the purpose of recanalization; the provided structure is low in cost and easy to operate. Simple, easy to use, strong controllability, helpful to improve diagnostic accuracy, easy to popularize and apply in the industry.
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本实用新型技术方案的保护范围之中。Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation.
