Description
技术领域 technical field
本发明涉及医疗器械，具体涉及一种一体化胸腔闭式引流装置。 The invention relates to a medical device, in particular to an integrated closed chest drainage device.
背景技术 Background technique
胸部创伤引起的各类气胸、血胸，都需要紧急施行救命性胸腔闭式引流术。至今的胸腔闭式引流术操作都是引流管插入胸膜腔后再与引流袋或引流瓶连接，引流管还需要缝针、缝线固定，这种传统的胸腔闭式引流术在平战时存在的主要问题是：（1）伤员必须后送到有条件的医院才能进行手术；（2）手术器械和必要设备不配套，均为临时组合；（3）手术需多人配合，不包括准备工作，手术熟练者大约需要15分钟左右. All kinds of pneumothorax and hemothorax caused by chest trauma require urgent life-saving closed chest drainage. So far, the operation of closed chest drainage is to insert the drainage tube into the pleural cavity and then connect it to the drainage bag or drainage bottle. The drainage tube needs to be fixed with needles and sutures. The main problems are: (1) The wounded must be evacuated to a qualified hospital for surgery; (2) The surgical instruments and necessary equipment are not matched, and they are all temporary combinations; (3) The operation requires the cooperation of multiple people, and does not include preparation work , It takes about 15 minutes for those who are skilled in the operation.
为适应平战时，特别是野战条件下胸伤伤员的快速急救，2012年麻晓林等对胸腔闭式引流器材进行评估、集成，首先研发出新型可分离式胸腔闭式引流穿刺针，不仅提高了穿刺的稳定性和可靠性，而且穿刺成功后，拔出针芯，插入引流管，针套退出皮肤后，即可分离开来，不必再按引流管的长度退出，这为研发一体化胸腔闭式引流装置奠定了基础。 In order to adapt to the rapid first aid of chest wounds in peacetime and wartime, especially in field conditions, in 2012, Ma Xiaolin et al. evaluated and integrated thoracic drainage equipment, and first developed a new detachable thoracic drainage puncture needle, which not only The stability and reliability of the puncture is improved, and after the puncture is successful, the needle core is pulled out, the drainage tube is inserted, and the needle sheath can be separated after it exits the skin, and it is not necessary to withdraw according to the length of the drainage tube, which is an integration of research and development Closed chest drainage devices laid the groundwork.
胸腔闭式引流是将引流管一端放入胸腔内，而另一端接入比其位置更低的水封瓶，以便排出气体或收集胸腔内的液体，使得肺组织重新张开而恢复功能。作为一种治疗手段广泛地应用于血胸、气胸、脓胸的引流及开胸术后，对于疾病的治疗起着十分重要的作用。胸腔闭式引流通常采用肋间插管的方法治疗。常用的引流装置有： Closed chest drainage is to put one end of the drainage tube into the chest cavity, and the other end is connected to a water-sealed bottle lower than its position, so as to expel air or collect fluid in the chest cavity, allowing the lung tissue to reopen and restore function. As a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases. Closed chest drainage is usually treated with an intercostal catheter. Common drainage devices include:
（1） 引流袋引流：适用于吸管引流，多用于引流胸腔积液。引流管直接接到一密封地所料引流袋。因没有水封瓶不能产生负压，因此，不适用肺内仍有漏气的病例。 (1) Drainage bag drainage: suitable for suction tube drainage, mostly used for drainage of pleural effusion. The drainage tube is directly connected to a sealed drainage bag. Because there is no water-sealed bottle, negative pressure cannot be generated, so it is not suitable for cases where there is still air leakage in the lungs.
（2）水封瓶引流：适用于大部分病例，可排出胸内积气、积液、积血及脓液。 (2) Water-sealed bottle drainage: it is suitable for most cases, and it can discharge pneumothorax, fluid, blood and pus in the chest.
（3）水封瓶负压吸引引流：因能加大胸内负压，故适用于胸内肺膨胀不良残腔较大的病例。 (3) Negative pressure suction and drainage of water-sealed bottle: Because it can increase the negative pressure in the chest, it is suitable for cases with large residual cavity of inflated lung in the chest.
在进行胸腔闭式引流的过程中，保持胸闭引流的密闭性和胸闭引流的通畅性是至关重要的。为此，有关人员开发了多种胸腔闭式引流装置。如CN2497795Y公开的一种瓣膜封闭式胸腔引流装置，由引流袋、引流管、排气管构成，引流管通过膜瓣式单向阀与引流袋上的引流接管连接，膜瓣式单向阀由封堵膜瓣粘结于管体上构成，封堵膜瓣为薄膜扁嘴锥筒体状，上口为圆口，下口为扁嘴，扁嘴两个角用弹性膜粘于管体内壁拉紧。该引流装置结构简单、应用方便、引流通畅、避免了任何情况下的回流、安全可靠、性能稳定、应用成本低、可广泛用于胸腔积液、水、浓、血及积气病人。又如CN03274837.X公开的一种多功能胸腔闭式引流装置，它包括有胸腔引流管、穿刺针和引流袋，胸腔引流管由带封堵胶塞的主管和侧管组成，主管上设有挡耳、气囊以及给气囊充气的导管，穿刺针穿在胸引管主管内，引流袋上设有排气隔液阀、放液阀、肝素帽以及设在袋内将引流袋分隔成上下两部分的过滤网；胸腔引流管侧管的下端插入并固定在引流袋内，侧管的下端设有单向活瓣和外套管。该装置具有手术操作简便，引流管不易窜动，移动使用性好，引流液可收集和过滤回输的优点。上述胸腔闭式引流装置都有各自的特点，但在保证引流管固定可靠和通畅性及密闭性方面还存在不足，需要在结构上作出突破性的改进。 In the process of closed chest drainage, it is very important to maintain the tightness of the chest drainage and the patency of the chest drainage. For this reason, relevant personnel have developed multiple closed chest drainage devices. A valve-enclosed chest drainage device disclosed in CN2497795Y is composed of a drainage bag, a drainage tube, and an exhaust pipe. The plugging valve is bonded to the tube body. The plugging valve is in the shape of a thin-film flat-mouth cone, with a round mouth at the top and a flat mouth at the bottom. The two corners of the flat mouth are glued to the inner wall of the tube with elastic membranes. tension. The drainage device has the advantages of simple structure, convenient application, smooth drainage, avoiding backflow under any circumstances, safety, reliability, stable performance, low application cost, and can be widely used in patients with pleural effusion, water, thick, blood and pneumatosis. Another example is a kind of multifunctional closed chest drainage device disclosed by CN03274837.X, which includes a chest drainage tube, a puncture needle and a drainage bag. The ear block, the air bag and the catheter for inflating the air bag, the puncture needle is inserted into the main pipe of the chest drainage tube, and the drainage bag is equipped with an exhaust and liquid isolation valve, a liquid discharge valve, a heparin cap, and the drainage bag is divided into upper and lower parts. Part of the filter screen; the lower end of the side tube of the chest drainage tube is inserted and fixed in the drainage bag, and the lower end of the side tube is provided with a one-way valve and an outer sleeve. The device has the advantages of simple operation, no easy movement of the drainage tube, good mobility and usability, and the drainage fluid can be collected, filtered and reinfused. The above-mentioned closed thoracic drainage devices have their own characteristics, but there are still deficiencies in ensuring the reliability, patency and airtightness of the drainage tube, and a breakthrough improvement in structure is required.

The effect of setting the helical spring bracket between the inner wall and the outer wall of the other end of the drainage tube is: when the other end of the drainage tube is inserted from the patient's intercostal space, it will not cause drainage due to the support of the helical spring bracket when it is squeezed. The tube is blocked to ensure smooth drainage.
进一步，在所述引流管1的另一端部的外壁配合连接有一哑铃形气囊套7，所述哑铃形气囊套与一充气管8的一端连通，所述充气管固定连接在所述引流管的外壁上，所述充气管的另一端与一充气球囊9的一端连接，所述充气球囊的另一端连接有一单向阀10。 Further, a dumbbell-shaped air bag cover 7 is connected to the outer wall of the other end of the drainage tube 1, and the dumbbell-shaped air bag cover communicates with one end of an inflatable tube 8, and the inflatable tube is fixedly connected to the drain tube. On the outer wall, the other end of the inflation tube is connected to one end of an inflatable balloon 9 , and the other end of the inflatable balloon is connected to a one-way valve 10 .
进一步，在所述引流管1的另一端部的外壁配合有一球囊盖11，该球囊盖与所述哑铃形气囊套位于胸腔插入口外的一端对应配合。设置球囊盖的作用是：避免意外的碰撞损坏充气后的哑铃形气囊套，从而进一步保证引流管固定的可靠性和密封性。 Further, a balloon cover 11 is matched with the outer wall of the other end of the drainage tube 1, and the balloon cover is correspondingly matched with the end of the dumbbell-shaped air bag sleeve outside the insertion port of the chest cavity. The function of setting the balloon cover is to prevent accidental collision from damaging the inflated dumbbell-shaped airbag cover, thereby further ensuring the reliability and sealing of the drainage tube fixation.
进一步，在所述引流袋2的上端设有排气阀12、下端设有排液阀13。 Further, an exhaust valve 12 is provided at the upper end of the drainage bag 2 , and a liquid discharge valve 13 is provided at the lower end.
进一步，所述引流袋2的容积为300ml～500ml。引流袋内壁涂有高分子化合物，能够有效的清洁血性和脓性物，避免附着在引流袋的内壁。 Further, the volume of the drainage bag 2 is 300ml-500ml. The inner wall of the drainage bag is coated with a polymer compound, which can effectively clean blood and purulent matter and avoid adhesion to the inner wall of the drainage bag.
在引流时，引流管及哑铃形气囊套在插入病员胸腔之前不充气，这时哑铃形气囊套的形状不固定，以便和引流管一起顺利插入病员胸腔；当引流管的另一端部从病员肋间插入至需要的深度后，再挤压充气球囊向哑铃形气囊套充气，使之形成哑铃形，哑铃形气囊套的中部较其两端小，且正好位于胸腔插入口处，由于充气后的哑铃形气囊套的两端中部较大且形状固定，一端位于胸腔插入口内，另一端位于胸腔插入口外，从而保证引流管固定可靠，不需再用针线缝合固，在病员移动时不会脱落，并且密闭性非常好。 During drainage, the drainage tube and the dumbbell-shaped airbag cover are not inflated before being inserted into the patient's chest cavity. After inserting between them to the required depth, squeeze the inflatable balloon to inflate the dumbbell-shaped airbag cover to form a dumbbell shape. The middle parts of both ends of the dumbbell-shaped air bag cover are large and fixed in shape, one end is located in the chest insertion port, and the other end is located outside the chest cavity insertion port, so as to ensure that the drainage tube is fixed and reliable, no need for stitches, and it will not fall off when the patient moves , and the tightness is very good.
