技术领域technical field
本发明涉及导尿管，尤其涉及一种防漏尿且防堵塞的导尿管，属于临床医疗技术领域。The invention relates to a urinary catheter, in particular to a urinary catheter that prevents urine leakage and blockage, and belongs to the technical field of clinical medicine.
背景技术Background technique
导尿管，是以硅胶为材料制成的管路，可以经由尿道插入膀胱以便引流尿液出来，导尿管插入膀胱后，靠近导尿管头端有一个气囊固定导尿管留在膀胱内，而不易脱出，且引流管连接尿袋收集尿液。导尿管在临床工作中广泛使用，如昏迷、截瘫、尿潴留、泌尿外科术后、膀胱尿道肿瘤等原因导致的尿液排泄不畅。The urinary catheter is a tube made of silica gel, which can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a balloon near the tip of the catheter to fix the catheter in the bladder. , It is not easy to come out, and the drainage tube is connected to the urine bag to collect urine. Urinary catheters are widely used in clinical work, such as poor urine excretion caused by coma, paraplegia, urinary retention, post-urological surgery, and bladder urethral tumors.
目前临床常用的导尿管，将尿管沿尿道插入膀胱后，经“气囊充气口”充气(或充水)，气囊膨开并卡在膀胱出口之上，起到固定、防止滑脱的作用。At present, the commonly used urinary catheter is inserted into the bladder along the urethra, then inflated (or filled with water) through the "air bag inflation port", and the air bag expands and is stuck on the bladder outlet to fix and prevent slippage.
但是，在导尿管的使用过程中，经常会遇到尿管堵塞的情况，尤其是对于泌尿系术后创面出血形成血凝块、尿路结石、或上尿路形成较多脓性、粘稠分泌物的患者。一旦导尿管堵塞，尿液或冲洗液就不能被及时引流至体外。一方面增加了病人痛苦，同时尿液潴留在上尿路易于发生感染，严重者可造成肾后性肾功能不全。However, during the use of the urinary catheter, the situation of urinary catheter blockage is often encountered, especially for the formation of blood clots, urinary calculi, or the formation of more purulent, viscous urinary tract in the postoperative wound of the urinary system. Patients with thick discharge. Once the catheter is blocked, urine or irrigation fluid cannot be drained out of the body in time. On the one hand, it increases the pain of the patient, and at the same time, urinary retention in the upper urinary tract is prone to infection, and severe cases can cause postrenal renal insufficiency.
其次，临床工作中，导尿管“尿漏”的问题也非常多见。可见于老年人、糖尿病病人神经源性膀胱、脑或脊髓损伤导致的尿失禁病人等。这些病人尿道括约肌松弛，张力低。因此，导致导尿管与尿道内壁之间结合不够紧密。即使插了导尿管，尿液仍然会顺着导尿管外壁与尿道之间的间隙流至尿道外口处。不仅给治疗和护理带来诸多不便，同时也增加了患者痛苦。此外，由于该通道是开放的，也易于发生尿路逆行感染。Secondly, in clinical work, the problem of urinary catheter "urinary leakage" is also very common. It can be seen in the elderly, diabetic patients with urinary incontinence caused by neurogenic bladder, brain or spinal cord injury, etc. In these patients, the urethral sphincter is relaxed and hypotonic. Therefore, the binding between the catheter and the inner wall of the urethra is not tight enough. Even if a catheter is inserted, urine will still flow to the outer opening of the urethra along the gap between the outer wall of the catheter and the urethra. It not only brings inconvenience to treatment and nursing, but also increases the suffering of patients. In addition, since this channel is open, it is also prone to retrograde urinary tract infections.
(一)针对尿管阻塞的问题：(1) For the problem of urinary catheter obstruction:
传统的方法是医生在导尿管末端连接上空的针管，利用空针负压抽出血凝块或正压冲开堵塞，使导尿管恢复通畅。The traditional method is that the doctor connects the needle tube in the space above the end of the catheter, and uses the negative pressure of the empty needle to draw out the blood clot or the positive pressure to wash away the blockage, so that the catheter can be recovered unobstructed.
公开号CN203736683U的发明公布了一种防堵塞导尿管，是在导尿管尾端出口附近设置一个球形或椭球形的弹性小球囊；导尿管发生堵塞时，挤压弹性小球囊使液体回流来疏通导尿管。该设计原理类似于目前临床上用空针反复抽吸尿管的操作。The invention of publication number CN203736683U discloses an anti-clogging urinary catheter, which is to arrange a spherical or ellipsoidal elastic small balloon near the outlet of the catheter tail end; The fluid backs up to unclog the catheter. The design principle is similar to the current clinical practice of repeatedly aspirating urinary catheters with an empty needle.
公开号CN104415449A的发明提供的改进方案为：气囊外侧设过滤网，在对气囊充气时，过滤网膨开填充于膀胱内部，对膀胱内血凝块等具有过滤作用。能阻挡膀胱内出血形成血凝块、膀胱结石等进入导尿管梗阻导尿管的管口。正因为如此，该设计不能把这些血凝块或小结石引流到体外。The improvement provided by the invention of publication number CN104415449A is: a filter screen is provided on the outside of the airbag. When the airbag is inflated, the filter screen expands and fills the inside of the bladder, which has a filtering effect on blood clots in the bladder. It can prevent bleeding in the bladder from forming blood clots, bladder stones, etc. from entering the catheter to block the nozzle of the catheter. Because of this, the design cannot drain these blood clots or small stones out of the body.
(二)针对“尿漏”的问题：(2) For the problem of "urine leakage":
公开号CN201643342U的发明提供的“尿漏”改进方案为：在现有导尿管球囊部位后侧添加一个软织的防漏挡板。该防漏挡板可依赖自身的弹力贴附于人体尿道粘膜上，从而更加有效地阻止尿液顺导尿管流出。The invention of publication number CN201643342U provides an improved "urine leakage" solution: add a soft woven leak-proof baffle on the rear side of the existing urinary catheter balloon. The leak-proof baffle can be attached to the mucous membrane of the human urethra by its own elasticity, thereby more effectively preventing urine from flowing out along the catheter.
公开号CN203763642U的发明提供了另一种“尿漏”改进方案：在现有导尿管球囊部位后侧添加一个充气球囊。该球囊充气后紧贴于尿道内壁，可一定程度上防止“漏”的发生。然而，该设计同上一个专利有同样的弊端。The invention of publication number CN203763642U provides another "urinary leakage" improvement: adding an inflatable balloon to the rear side of the existing urinary catheter balloon. After the balloon is inflated, it is closely attached to the inner wall of the urethra, which can prevent the occurrence of "leakage" to a certain extent. However, this design has the same drawbacks as the previous patent.
前述现有技术并没有解决尿管阻塞的问题：不论是空针加压疏通，还是在侧孔外加装滤过网装置，其真正的尿液流出口径仍然为导尿管前端的侧孔，尿液导流的有效面积仍然狭小。加压疏通只能解决一时堵塞，并未解决因为导尿管侧孔面积小，而造成管道堵塞这一根本原因，常需要反复疏通。The above-mentioned prior art does not solve the problem of urinary catheter blockage: no matter whether it is an empty needle pressurized to dredge, or a filter screen device is installed outside the side hole, the real urine outflow diameter is still the side hole at the front end of the catheter. The effective area for urine diversion is still narrow. Pressurized dredging can only solve temporary blockage, but does not solve the root cause of pipeline blockage due to the small area of the side hole of the urinary catheter, and repeated dredging is often required.
在狭小的侧孔被完全封堵之后，生物组织覆盖物(如血凝块、组织碎屑等)与侧孔结合紧密，空气针做活塞运动时产生的气体的压力不足以将堵塞口处的生物组织覆盖物冲出，此时，需更换新的导尿管，而新的导尿管由于侧孔结构一样也并没有从根本上解决上述堵塞问题，仅仅是新一轮的堵塞循环。同时，更换导尿管，也易增大尿路感染几率，给病人带来很大痛苦。After the narrow side hole is completely blocked, the biological tissue covering (such as blood clot, tissue debris, etc.) is tightly combined with the side hole, and the pressure of the gas generated when the air needle is piston-moving is not enough to remove the gas at the plugged hole. Biological tissue covering rushes out, and at this moment, need to change new urinary catheter, and new urinary catheter also does not fundamentally solve above-mentioned blockage problem because of side hole structure, is just a new round of blockage cycle. At the same time, changing the urinary catheter also easily increases the chance of urinary tract infection, which brings great pain to the patient.
当膀胱存在化脓性炎症时，由于脓液稠厚，脓性尿液在过滤网与侧孔之间的类球状腔道时，脓尿液拥堵，易形成湍流，流速显著减慢，较小的侧孔内脓液若是未及时彻底引流则进一步加重感染。When there is purulent inflammation in the bladder, due to the thick pus, when the purulent urine is in the ball-like cavity between the filter screen and the side hole, the purulent urine is congested and turbulent flow is easily formed, and the flow rate is significantly slowed down. If the pus in the side hole is not drained in time, the infection will be further aggravated.
增加的滤网仅仅是起到将膀胱内的血凝块或组织碎屑等有形物质拦截在导尿管之外，留存并积聚于膀胱内部。这些理应随尿液排泄的有形物质在膀胱内的留存，必然对人体造成危害。The added filter screen only acts to intercept tangible substances such as blood clots or tissue debris in the bladder outside the catheter, retain and accumulate in the bladder. These tangible substances that should be excreted with urine remain in the bladder, which will inevitably cause harm to the human body.
现有技术在处理“尿漏”问题的同时，带来了严重的并发症：一旦导尿管插入后，单一的防漏挡板或尿道内气囊装置便一直压在尿道内壁粘膜上，随着时间延长，该处粘膜易于发生缺血、坏死或纤维化，继而并发各种严重并发症：如尿道穿孔、狭窄、粘连等。因此，鉴于尿道的生理结构特点，现有的防“尿漏”技术长时间压迫尿道内壁粘膜，会造成严重的并发症。While the existing technology is dealing with the problem of "urinary leakage", it brings serious complications: once the catheter is inserted, the single leak-proof baffle or the balloon device in the urethra is always pressed against the inner wall of the urethra. Over time, the mucosa is prone to ischemia, necrosis or fibrosis, followed by various serious complications such as urethral perforation, stenosis, and adhesions. Therefore, in view of the physiological structural characteristics of the urethra, the existing anti-"urine leakage" technology compresses the mucous membrane of the inner wall of the urethra for a long time, which will cause serious complications.

如图1至图4所示，所述自膨胀开口段2由灯笼状骨架构成；所述管体15由硅胶材料制成；所述自膨胀开口段2由记忆金属材料制成。As shown in FIGS. 1 to 4 , the self-expanding opening section 2 is made of a lantern-shaped skeleton; the tube body 15 is made of silicone material; and the self-expanding opening section 2 is made of memory metal material.
本发明的主要特点在于：Main features of the present invention are:
1、导尿管自膨胀开口段2由特殊记忆金属材料制作，在含有导丝的导尿管管体15中，可以凭借导丝的牵拉支撑作用，向前方缩窄变细，保证导尿管可以沿尿道顺利进入膀胱；当导尿管管体15进入膀胱腔内，在没有导丝牵拉的情况下能自动膨开，膨胀后如镂空的灯笼骨架，较传统的数量和直径均有限的侧孔，能显著地扩大了尿液引流的开口面积，减少流出门径的堵塞几率。1. The self-expanding opening section 2 of the urinary catheter is made of a special memory metal material. In the catheter body 15 containing the guide wire, it can be narrowed and thinned forward by the pulling support of the guide wire to ensure catheterization. The tube can smoothly enter the bladder along the urethra; when the catheter body 15 enters the bladder cavity, it can expand automatically without the pull of the guide wire. After expansion, it looks like a hollowed-out lantern skeleton. The side hole can significantly expand the opening area of urine drainage and reduce the chance of blockage of the outflow path.
自膨胀开口段2技术记忆骨架之间有一定的间隔，可以允许一定体积的血凝块、结石、组织碎屑等有形物质通过导尿管管体15自行流出体外，或外接真空针管，在后者一定的负压吸引力帮助下吸出。减少有害的有形物质在膀胱里的留存和聚集，减少对人体的损害。There is a certain interval between the self-expanding opening section 2 technical memory skeletons, which can allow a certain volume of tangible substances such as blood clots, calculus, tissue debris to flow out of the body through the catheter body 15, or an external vacuum needle tube, after It is sucked out with the help of a certain negative pressure attraction. Reduce the retention and accumulation of harmful tangible substances in the bladder, and reduce the damage to the human body.
该自膨胀开口段2与其前后硅胶管体15紧密无缝连接。The self-expanding opening section 2 is closely and seamlessly connected with the front and back silicone tube bodies 15 .
自膨胀开口段2的灯笼状骨架也可依据成人、儿童、以及不同疾病引流尿液需要设计成不同间距、不同大小的骨架形状。The lantern-shaped skeleton of the self-expanding opening section 2 can also be designed into skeleton shapes with different spacings and sizes according to the urine drainage needs of adults, children, and different diseases.
2、两个独立的防漏尿气囊一4和防漏尿气囊二5，在导尿管体15的硅胶管壁中有两条独立的防漏尿充气通道充气后均可封闭导尿管外侧壁与尿道内壁之间的间隙，从而起到防漏的目的。两个防漏气囊交替充气，当防漏尿气囊一4充盈执行防漏尿功能时，防漏尿气囊二5应于排气空瘪状态，减轻气囊对该段尿道内壁的压力，增加尿道内壁粘膜的组织供血，避免该处因气囊长时间压迫尿道内壁组织造成粘膜缺血坏死；防漏尿气囊二5充盈执行防漏尿功能时，则防漏尿气囊一4处于排气空瘪状态，原理同上。2. Two independent urine-leakage-proof airbags one 4 and urine-leakage-proof airbag two 5, there are two independent urine-leakage-proof inflatable channels in the silicone tube wall of catheter body 15, which can seal the outside of the catheter after inflated The gap between the wall and the inner wall of the urethra to prevent leakage. The two anti-leakage airbags are inflated alternately. When the anti-leakage airbag 1 is inflated to perform the function of preventing urine leakage, the anti-leakage airbag 2 5 should be in the exhausted and deflated state to reduce the pressure of the airbag on the inner wall of the urethra and increase the pressure on the inner wall of the urethra. The tissue of the mucosa supplies blood to avoid ischemia and necrosis of the mucosa caused by the long-term pressure of the air bag on the inner wall of the urethra. The principle is the same as above.
3、防漏尿气囊充气接口可以选择性连接三通道(闭塞档、充放防漏尿气囊一档、充放防漏尿气囊二档)可调节，可任意选择给防漏尿气囊一4或防漏尿气囊二5进行充、放气操作，设计简单易于生产，操作方便易于实施。3. The inflatable interface of the anti-leakage airbag can be selectively connected to three channels (blocking gear, the first gear for filling and discharging the urine-proof airbag, and the second gear for filling and discharging the urine-proof airbag). The anti-leakage urine air bag 25 is inflated and deflated, the design is simple and easy to produce, and the operation is convenient and easy to implement.
4、导丝前端为钝圆膨大设计，在导丝向导尿管体15前盲端1延生的过程中，防止导丝从镂空的自膨胀开口段2的记忆材料骨架间隙处滑出，以免损伤尿道内壁和膀胱内壁。4. The front end of the guide wire is designed to be blunt and enlarged. During the process of extending the guide wire to the front blind end 1 of the urinary catheter body 15, the guide wire is prevented from slipping out from the gap of the memory material skeleton of the hollow self-expanding opening section 2, so as to avoid damage The lining of the urethra and the lining of the bladder.
5、如图1至图4所示，是基于普通导尿管设计。导尿管长短可依据成人、儿童、性别等设计成不同规格；导尿管管体15直径为适应人体尿道直径不同设计成不同管径大小。在功能方面，可设计二腔道具有膀胱给药或灌注功能的防漏尿、防堵塞导尿管，如图5所示。创新设计多通道气囊充气接口10，拥有四个档位(闭塞档、充放防漏尿气囊一档、充放防漏尿气囊二档、充放防滑脱气囊6档)。空余的下方的一个通道和接口，设计成为给药灌注通道，以满足在不增加额外通道口的情况下，增加对膀胱进行给药或灌注冲洗的功能。5. As shown in Figures 1 to 4, it is based on the design of common urinary catheters. The length of the urinary catheter can be designed into different specifications according to adults, children, gender, etc.; the diameter of the catheter tube body 15 is designed to be different in diameter for adapting to the different diameters of the human urethra. In terms of function, it is possible to design a urine-leakage and blockage-proof catheter with a two-chamber bladder drug delivery or perfusion function, as shown in Figure 5. The innovatively designed multi-channel airbag inflation interface 10 has four gears (blocking gear, first gear for filling and discharging the anti-leakage airbag, second gear for filling and discharging the anti-leakage airbag, and six gears for filling and discharging the anti-slip airbag).
