一种用于开放性孔道损伤的密闭型敷料An occlusive dressing for open porosity injuries

技术领域technical field

本发明涉及创面防护领域，涉及一种用于开放性孔道损伤的密闭型敷料。The invention relates to the field of wound protection, in particular to an airtight dressing for open channel injuries.

背景技术Background technique

在临床手术中，开放性孔形伤口常见于需要使用骨骼外固定针和使用引流管的场合。骨折外固定针是临床上常用的一种骨折固定形式，适用于骨折断端无法加压等多种情景；胸腹腔部术后患者普遍留置引流管，用于术后排除积气、积液、积血，维持器官功能和血流动力学稳定，有利于器官功能尽早恢复。In clinical operations, open hole-shaped wounds are common in occasions that require the use of external bone fixation pins and drainage tubes. Fracture external fixation pins are a commonly used form of fracture fixation in clinical practice, and are suitable for many situations such as fracture ends that cannot be pressurized; patients after thoracoabdominal surgery generally have indwelling drainage tubes for postoperative removal of gas, fluid, Hemorrhage maintains organ function and hemodynamic stability, which is conducive to the early recovery of organ function.

固定针与引流管与皮肤形成的伤口有以下特点：1、创面易出血，而且是持续的过程。由于异物存在，伤口处于长期无法愈合的状态，而且会伴随出血和组织液渗出的状态，所以需要吸湿性的敷料；2、易感染，骨针或者引流管一端嵌入皮肤，一端暴露在皮肤外，细菌可沿着钉道逆行进入皮下组织，导致感染，统计数据显示，骨折中感染概率约为70-80％，由于外固定引发的骨髓炎发生的概率约为10％左右；而引流管感染的发生率通常在1.7％-70％之间。易造成细菌侵入，引发腹腔、胸腔或者颅内感染，对患者造成伤害、影响术后恢复效果；3、骨针或引流管的孔道易松动，骨针一端嵌入骨骼，骨骼壁较薄，存在松动的风险，而引流管固定不牢固或者过度牵拉可能导致非计划性拔管或者意外脱管。The wound formed by the fixed needle, the drainage tube and the skin has the following characteristics: 1. The wound surface is easy to bleed, and it is a continuous process. Due to the presence of foreign matter, the wound is in a state that cannot heal for a long time, and will be accompanied by bleeding and interstitial fluid leakage, so a hygroscopic dressing is required; 2. Susceptible to infection, one end of the bone needle or drainage tube is embedded in the skin, and the other end is exposed outside the skin. Bacteria can enter the subcutaneous tissue retrogradely along the screw path, leading to infection. Statistics show that the probability of infection in fractures is about 70-80%, and the probability of osteomyelitis caused by external fixation is about 10%. The incidence is usually between 1.7%-70%. It is easy to cause bacterial invasion, cause abdominal cavity, chest cavity or intracranial infection, cause injury to patients, and affect postoperative recovery effect; 3. The hole of the bone needle or drainage tube is easy to loose, and one end of the bone needle is embedded in the bone, and the bone wall is thin and loose. Inadequate or excessive stretching of the drainage tube may lead to unplanned extubation or accidental dislodgement.

传统的护理方法如通常使用酒精、碘伏等消毒剂，对伤口进行消杀，该方法刺激性较强，易引起疼痛或者皮肤过敏，钉道周围产生肉芽组织等风险。纱布包裹也是临床上常用的护理方式，即将纱布缠绕在钉道或引流管周围，该方法需要用胶布进行额外固定，上药操作需要一定专业技术，操作不当时纱布容易发生脱落及位移，且换药时纱布可能会和伤口发生粘连，容易给患者带来痛苦。另一种常用的包裹方式是将敷料贴剪成Y型缺口或者用引流管用敷料贴进行固定，但是敷料贴底部清洁困难，容易滋生细菌导致逆行性感染，吸水后黏附性降低，易脱落。有些患者钉道局部出血、渗出较严重，很可能超过敷贴的吸收能力。此外，现有的引流管固定贴不能完全满足钉道伤口的实际需求，例如，不能根据钉道的直径实现自适应，造成现有的引流管固定贴密封性较弱，细菌容易侵入引起感染等。Traditional nursing methods such as alcohol, iodophor and other disinfectants are usually used to disinfect the wound. This method is highly irritating and can easily cause pain or skin allergies, and the risk of granulation tissue around the nail track. Gauze wrapping is also a commonly used nursing method in clinical practice, that is, wrapping gauze around the nail channel or drainage tube. This method requires additional fixation with adhesive tape, and the operation of applying medicine requires certain professional skills. The gauze may adhere to the wound during the medicine, which is easy to cause pain to the patient. Another commonly used wrapping method is to cut the dressing into a Y-shaped gap or fix it with a drainage tube. However, it is difficult to clean the bottom of the dressing, and it is easy to breed bacteria and cause retrograde infection. After absorbing water, the adhesion is reduced and it is easy to fall off. In some patients, the local bleeding and exudation of the nail channel are serious, which may exceed the absorption capacity of the application. In addition, the existing drainage tube fixation patch cannot fully meet the actual needs of the nail track wound, for example, it cannot be self-adapted according to the diameter of the screw track, resulting in weak sealing performance of the existing drainage tube fixation patch, and bacteria are easy to invade and cause infection, etc. .

在现有的专利技术一种立体创面敷料贴(申请号：202010521256.2)提供了两种实施方案，一种方案是通过两个主半圆柱形包裹部拼合形成中间具有通道的立体敷料贴，这种方案的缺点在于两个主半圆柱形包裹部通过粘合剂拼合，换药时需要强行向外侧扯开敷料，拆除较为困难且可能对伤口造成损伤；另一种技术方案为具有圆柱形通道和侧面通槽的锥形敷料，这种方案的缺点在于没有针对侧面通槽进行任何密封处理，细菌能够轻易通过通槽进入伤口，容易造成伤口感染。In the existing patent technology, a three-dimensional wound dressing (application number: 202010521256.2) provides two implementations. One solution is to combine two main semi-cylindrical wrapping parts to form a three-dimensional dressing with a channel in the middle. The disadvantage of the solution is that the two main semi-cylindrical wrapping parts are joined together by adhesive, and the dressing needs to be forcibly torn apart when changing the dressing, which is difficult to remove and may cause damage to the wound; another technical solution is to have a cylindrical channel and Conical dressing with side channel, the disadvantage of this solution is that there is no sealing treatment for the side channel, bacteria can easily enter the wound through the channel, and it is easy to cause wound infection.

综上所述，本领域需要提供一种用于开放性孔道损伤的密闭型敷料，其能够克服现有技术的缺陷。To sum up, there is a need in the art to provide an airtight dressing for open channel injuries, which can overcome the defects of the prior art.
