背景技术Background technique
烧烫伤是人类日常生活、生产、战争等活动最常见的急性损伤之一。较严重烧烫伤传统治疗方法不仅病人极度痛苦,而且面临创面愈合延迟,愈后疤痕残留等问题,甚至危及病人生命!如何根据病人烧烫伤创面的病理生理特点,改进临床治疗方法和治疗方案至关重要,社会效益和经济效益巨大。Burns and burns are one of the most common acute injuries in daily life, production, war and other activities. The traditional treatment method for severe burns and burns is not only extremely painful for the patient, but also faces problems such as delayed wound healing, residual scars after the healing, and even endangering the patient's life! How to improve the clinical treatment methods and treatment plans according to the pathophysiological characteristics of patients with burn wounds is very important, and the social and economic benefits are huge.
烧烫伤常用的临床等级分布如下:The clinical grades commonly used for burns are as follows:
1)、Ⅰ度烧伤,又称红斑性烧伤,仅伤及表皮的一部分,但生发层健在,因而增殖再生能力活跃,常于3~5天内愈合,不留瘢痕。1), I degree burns, also known as erythema burns, only a part of the epidermis, but the germinal layer is healthy, so the proliferation and regeneration ability is active, often healed within 3 to 5 days, leaving no scars.
2)、浅Ⅱ度烧伤,指的是伤及整个表皮和部分乳头层。由于生发层部分受损,上皮的再生有赖于残存的生发层及皮肤附件,如汗腺及毛囊的上皮增殖。如无继发感染,一般经1~2周左右愈合,亦不留瘢痕。2), shallow second degree burns, refers to the injury of the entire epidermis and part of the papillary layer. Due to the partial damage of the germinal layer, the regeneration of the epithelium depends on the residual germinal layer and skin attachments, such as epithelial proliferation of sweat glands and hair follicles. If there is no secondary infection, it usually heals in about 1 to 2 weeks, and no scars are left.
3)深Ⅱ度烧伤,指的是烧伤深及真皮乳头层以下,但仍残留部分真皮及皮肤附件,愈合依赖于皮肤附件上皮,特别是毛囊突出部内的表皮祖细胞的增殖。如无感染,一般需3~4周自行愈合,常留有瘢痕。临床变异较多,浅的接近浅Ⅱ度,深的则临界Ⅲ度。3) Deep second degree burn refers to the deep burn and below the dermal papilla layer, but still remains part of the dermis and skin attachment. The healing depends on the epithelium of the skin attachment, especially the proliferation of epidermal progenitor cells in the hair follicle protrusion. If there is no infection, it usually takes 3 to 4 weeks to heal itself, often with scars. The clinical variation is more, the shallow is close to the shallow II degree, and the deep is the critical III degree.
4)Ⅲ度烧伤,又称焦痂性烧伤。一般指全程皮肤的烧伤,表皮、真皮及皮肤附件全部毁损,创面修复依赖于手术植皮或皮瓣修复。4) III degree burn, also known as eschar burn. Generally refers to the burn of the whole skin, the epidermis, dermis and skin attachments are all destroyed, and the wound repair depends on the surgical skin graft or flap repair.
5)Ⅳ度烧伤,指的是烧伤深及肌肉、骨骼甚至内脏器官,创面修复依赖于手术植皮或皮瓣修复,严重者需截肢。5) Grade IV burn refers to deep burns and muscles, bones and even internal organs. Wound repair depends on surgical skin graft or flap repair. In severe cases, amputation is required.
因为烧烫伤致病因子的损伤特点,人体烧烫伤损伤程度往往是混合型分布的。Because of the damage characteristics of the scald disease-causing factors, the degree of burn injury in the human body is often mixed.
烧烫伤局部创面重要的病理生理特征如下:The important pathophysiological features of burned local wounds are as follows:
烧烫伤局部组织的损伤分三层:凝固坏死带、淤滞带、充血带。其中瘀滞带代表部分组织损伤,属“间生态”状态,充血带和淤滞带组织的主要改变是毛细血管通透性增加和扩张;血流缓慢和容易发生微血管栓塞;使局部组织缺氧并造成对全身的影响。小面积烧伤明显的水肿仅限于烧伤部位,全身反应不明显;较严重的烧伤,水肿可出现在烧伤邻近部位的组织中;极严重的烧伤,水肿可见于全身包括内脏组织等。The local tissue damage caused by burns and burns is divided into three layers: coagulation necrosis zone, stasis zone, and congestion zone. The stagnant zone represents part of the tissue damage, which is an "inter-ecological" state. The main changes in the hyperemia zone and the stasis zone are increased capillary permeability and expansion; slow blood flow and prone to microvascular embolism; Causes an effect on the whole body. The obvious edema of small area burn is limited to the burn site, and the systemic reaction is not obvious. For severe burns, edema can occur in the tissues adjacent to the burn; extremely severe burns and edema can be found in the whole body including visceral tissues.
是否会出现全身障碍取决于烧伤的面积大小,临床上Ⅰ度烧伤一般无需治疗,Ⅱ度以上烧烫伤成人烧伤面积达15%以上时即可发生全身功能障碍的标志。即:①渗出休克阶段;②液化中毒阶段;③伤口修复愈合阶段;④功能康复阶段。Whether there will be systemic disorders depends on the size of the burn, clinically, I degree burns generally do not require treatment, and the degree of systemic dysfunction can occur when the burn area of adults with burns of more than 2 degrees is more than 15%. Namely: 1 oozing shock stage; 2 liquefaction poisoning stage; 3 wound repair healing stage; 4 functional rehabilitation stage.
目前临床上烧烫伤局部创面处置仍然以手术、换药等治疗方法为主。根据伤员情况不同,医生也会使用医用材料或药物,例如:人皮、猪皮生物材料;高端吸液敷料;环氨嘧啶银等烧烫膏剂、粉剂等。At present, the treatment of local burn wounds in clinical burns is still based on treatments such as surgery and dressing change. Depending on the condition of the casualty, doctors also use medical materials or drugs, such as: human skin, pig skin biomaterials; high-end aspirate dressings; arsenazo silver and other hot pastes, powders, etc.
烧烫伤创面局部手术、换药等处置,不仅伤员极度痛苦,而且损伤大。目前各种医用材料或药物因为用途单一,均存在不同的问题。如何让烧烫伤创面局部处置少换药、少手术,甚至部分病例无需手术即可创面愈合。随着科学技术的发展,即符合外科微创化的发展方向,也已具有现实可能性。Local operations such as burns and burns, dressing changes, etc., not only the wounded are extremely painful, but also the damage. At present, various medical materials or drugs have different problems due to their single use. How to make the burned burn wounds local treatment less dressing change, less surgery, and even some cases can be wounded without surgery. With the development of science and technology, that is, in line with the development direction of surgical micro-invasiveness, it has realistic possibilities.
在烧烫伤创面的急性渗出阶段,临床创面局部处置面临的主要问题是渗液多,渗液管理、血液循环障碍、创面水肿等问题。临床上不仅要处理好以上问题,而且要尽可能挽 “间生态”损伤组织和细胞。人皮、猪皮生物材料、高端吸水敷料等覆盖创面不仅面临创面积液导致感染等问题;而且每天换药,医生工作量巨大,病人极端疼痛。检索文献报道,亦无换药处置方法:人皮、猪皮生物材料;高端吸水敷料等挽救“间生态”受损组织等直接作用。In the acute exudation stage of burn wounds, the main problems faced by local treatment of clinical wounds are many exudates, fluid management, blood circulation disorders, and wound edema. Clinically, we must not only handle the above problems, but also try to "Inter-ecological" damages tissues and cells. Covering wounds such as human skin, pig skin biomaterials, and high-end absorbent dressings not only face problems such as infection caused by wounded area fluid; but also changing the medicine every day, the doctor has a huge workload and the patient is extremely painful. Search literature reports, there is no dressing disposal method: human skin, pig skin biomaterials; high-end absorbent dressings and other direct effects such as saving the "inter-ecological" damaged tissue.
在烧烫伤创面的坏死组织液化和修复愈合阶段,坏死组织层不仅形成站位,导致残留真皮和皮肤附件新生上皮和皮岛的无法生长,而且坏死组织溶化毒素吸收有可能导致伤员全身中毒。临床上传统采用削痂和切痂手术,解除坏死组织站位。但因为坏死组织层和正常组织界线不清,手术过程中将不可避免地造成正常组织损伤。传统的生物材料和烧烫伤药物等均无法解决以上问题。In the liquefaction and repair healing stage of necrotic tissue in burn wounds, the necrotic tissue layer not only forms a standing position, but also leads to the growth of residual dermis and skin attachment neoplastic epithelium and skin island, and the absorption of necrotic tissue dissolved toxin may cause systemic poisoning of the wounded. Clinically, the use of cutting and cutting surgery to remove necrotic tissue sites. However, because the necrotic tissue layer and the normal tissue boundary are unclear, normal tissue damage will inevitably occur during the operation. Traditional biomaterials and burns and scalds do not solve the above problems.
另外,烧烫伤创面局部修复的过程就是残留的真皮或皮肤附件首先局部形成“新生上皮细胞”和“皮岛”。但“新生上皮细胞”和“皮岛”细胞之间的链接是逐渐形成的,开始时细胞之间链接松散,易于脱落。目前临床各种治疗方法均存在真皮层逐渐生发的新生上皮细胞和“皮岛”与渗液残留部分、坏死组织界限不清的现象。传统临床治疗需反复多次换药、清创。清创或换药因为医生操作用力,即使是用棉球擦拭等轻微动作,也有可能造成新生细胞一定程度的损伤,甚至被清除脱落的状况,导致创面延迟愈合等。In addition, the local repair process of burn wounds is that the residual dermis or skin attachment first forms "new epithelial cells" and "peel islands". However, the link between the "new epithelial cells" and the "peel island" cells is gradually formed, and the links between the cells are loose at the beginning and are easy to fall off. At present, various clinical treatment methods have the phenomenon that the neoplastic epithelial cells and the "peel island" which are gradually germinated in the dermis layer and the residual part of the exudate and the necrotic tissue are unclear. Traditional clinical treatment requires repeated dressing changes and debridement. Debridement or dressing change Because of the force of the doctor's operation, even a slight movement such as wiping with a cotton ball may cause a certain degree of damage to the newborn cells, or even be removed and fall off, resulting in delayed healing of the wound surface.
如何改进临床治疗方法,解决以上各种问题,新技术和产品能够做到在烧烫伤创面的急性渗出阶段尽可能抢救“间生态受损组织和细胞”。烧烫伤创面的修复愈合阶段,找到 “溶痂”、“清除坏死组织站位”、“避免坏死组织溶化毒素被吸收”与无损伤保留新生上皮细胞和新生“皮岛”的平衡。减少手术,减少换药,开辟新的烧烫伤创面微创治疗方案和方法,及其重要! How to improve the clinical treatment methods to solve the above problems, new technologies and products can be able to rescue "inter-implanted tissues and cells" in the acute exudation stage of burn wounds. Burning burn wounds repair healing stage, found "Solution", "clearing necrotic tissue sites", "avoiding necrotic tissue solubilized toxins are absorbed" and the balance of intact neonatal epithelial cells and newborn "peel islands" without damage. Reduce surgery, reduce dressing changes, and open up new minimally invasive treatment plans and methods for burn wounds, and their importance!

本发明的有益效果是:本发明通过贴翼贴在患者烧伤处边沿外侧皮肤表面后医用贴膜下方形成的引流材料吸液腔,湿度传感器感应到吸液腔中的湿度,将信号反馈到智能控湿主机中的芯片控湿系统,若检测到吸液腔中的湿度浓度超过预定值后,真空泵工作并提供抽吸动力,通过储液瓶、抽吸导管、引流敷料层以及吸盘将吸液腔中的液体吸走,使得吸液腔中的湿度维持在80~90%的稳定水平。这样一来。在烧烫伤创面急性渗出阶段,创面渗液多,本发明具有渗液管理功能;同时本发明通过引流敷料层和医用贴膜形成的创面局部封闭吸附腔,真空泵抽吸吸附腔形成的间歇性微真空环境不仅有利于创面消肿,而且可以促进创面血液循环障碍恢复,改善“间生态”休克细胞病理生理状态,尽可能挽救“间生态”受损组织和细胞。在烧烫伤创面的坏死组织液化和修复愈合阶段,本发明无论创面渗液多少,通过加液管创面局部补液,及其自动控制创面湿度,维持创面适当“干湿度”,有利于“溶痂”和解除坏死组织层站位,通过吸附腔和真空泵抽吸作用,将已溶化的坏死组织和渗出液抽离创面,减少了需要“削痂”、“切痂”等手术的可能性。本发明通过控制医用贴膜和引流敷料层形成的吸附腔内间歇性微真空,不仅可以皮面较大真空度存在挤压患者创面疼痛的副作用,而且可以促进局部血液循环,有利于残留真皮和皮肤附件新生上皮细胞和皮岛。另外,因为创面溶化组织和创面渗出液流体阻力较小,容易被抽吸清除;而新生上皮细胞和皮岛附着在正常皮肤上,与正常组织一体化,不易被抽吸脱落,耐受真空抽吸作用较强,所以通过智能控湿主机控制,临床上掌握适当大小的真空度,不仅能够做到创面 坏死组织“溶痂”、“清除坏死组织站位”,而且可以达到“抽吸避免坏死组织溶化毒素被吸收”与无损伤保留新生上皮细胞和新生“皮岛”的作用,加速创面愈合。本发明将减少烧烫伤创面治疗传统手术和换药的方法,减轻医生工作量,极大地减少伤员疼痛和传统治疗副损伤。The invention has the beneficial effects that the invention is attached to the liquid suction cavity of the drainage material formed under the medical film on the outer skin surface of the patient's burn site, and the humidity sensor senses the humidity in the liquid suction cavity, and the signal is fed back to the intelligent control. In the chip-controlled humidity system in the wet host, if the humidity concentration in the aspiration chamber exceeds a predetermined value, the vacuum pump operates and provides suction power, and the liquid suction chamber is passed through the liquid storage bottle, the suction catheter, the drainage dressing layer, and the suction cup. The liquid in the liquid is sucked away, so that the humidity in the liquid suction chamber is maintained at a stable level of 80 to 90%. Thus. In the acute exudation stage of burn wounds, there are many exudates in the wound surface, and the invention has the function of exudate management; at the same time, the wound surface formed by the drainage dressing layer and the medical film partially closes the adsorption chamber, and the vacuum pump suctions the intermittent micro-form formed by the adsorption chamber.

In the stage of liquefaction and repair healing of necrotic tissue in burn wounds, the present invention not only sees the amount of exudate on the wound surface, but also locally controls the wound surface by adding liquid tube, and automatically controls the humidity of the wound surface to maintain proper "dry humidity" of the wound surface, which is beneficial to "solvent". And the site of the necrotic tissue layer is removed, and the dissolved necrotic tissue and exudate are pumped away from the wound through the suction chamber and the vacuum pump, thereby reducing the possibility of requiring "cutting" and "cutting". The invention can control the intermittent micro-vacuum in the adsorption cavity formed by the medical film and the drainage dressing layer, and can not only have the side effect of squeezing the pain of the wound in the patient with a large degree of vacuum on the leather surface, but also can promote local blood circulation, and is beneficial to residual dermis and skin. Attached to neonatal epithelial cells and skin islands. In addition, because the fluid-dissolving tissue and wound exudate fluid resistance is small, it is easy to be removed by suction; while the neonatal epithelial cells and skin islands are attached to normal skin, integrated with normal tissues, not easily sucked off, and withstand vacuum The suction effect is strong, so through the intelligent humidity control host control, clinically grasp the appropriate degree of vacuum, not only can achieve wounds The necrotic tissue "dissolves" and "clears the necrotic tissue station", and can achieve the effect of "sucking to avoid the absorption of necrotic tissue dissolved toxins" and non-invasive retention of neoplastic epithelial cells and neonatal "peel island" to accelerate wound healing. The invention will reduce the method of treating burns and wounds to treat traditional surgery and dressing, reduce the workload of doctors, and greatly reduce the pain of the wounded and the traditional treatment side damage.

The program set in the chip moisture control system of the intelligent humidity control host 5 is that after the humidity sensor detects that the humidity of the liquid suction chamber exceeds 90%, the vacuum pump stops after 5 minutes of operation. If after 5 minutes, the humidity sensor detects that the humidity of the aspiration chamber exceeds 90%, the vacuum pump restarts. The tube that communicates with the interior of the reservoir is a suction conduit 40. The tube that communicates with the suction suction cup 2 can be a suction conduit 40 or a connection conduit 3.
通过贴翼贴在患者烧伤处边沿外侧皮肤表面后医用贴膜10下方形成的引流材料吸液腔,湿度传感器感应到吸液腔中的湿度,将信号反馈到智能控湿主机5中的芯片控湿系统,若检测到吸液腔中的湿度浓度超过预定值后,真空泵工作并提供抽吸动力,通过储液瓶4、抽吸导管40、引流敷料层1以及吸盘将吸液腔中的液体吸走,使得吸液腔中的湿度维持在80~90%的稳定水平。这样一来。在烧烫伤创面急性渗出阶段,创面渗液多,本发明具有渗液管理功能;同时本发明通过引流敷料层1和医用贴膜10形成的创面局部封闭吸附腔,真空泵抽吸吸附腔形成的间歇性微真空环境不仅有利于创面消肿,而且可以促进创面血液循环障碍恢复,改善“间生态”休克细胞病理生理状态,尽可能挽救“间生态”受损组织和细胞。在烧烫伤创面的坏死组织液化和修复愈合阶段,本发明自动控制创面湿度,有利于“溶痂”和解除坏死组织层站位,通过吸附腔和真空泵抽吸作用,将已溶化的坏死组织和渗出液抽离创面,减少了需要“削痂”、“切痂”等手术的可能性。本发明通过控制医用贴膜10和引流辅料层形成的吸附腔内间歇性微真空,可以促进局部血液循环,有利于残留真皮和皮肤附件新生上皮细胞和皮岛。另外,因为创面溶化组织和创面渗出液流体阻力较小,容易被抽吸清除;而新生上皮细胞和皮岛与正常组织一体化,不易被抽吸脱落,耐受真空抽吸作用较强;所以通过智能控湿主机5控制,临床上掌握适当大小的真空度,能够做到创面 “溶痂”、“清除坏死组织站位”、“避免坏死组织溶化毒素被吸收”与无损伤保留新生上皮细胞和新生“皮岛”的平衡,加速创面愈合。本发明将减少烧烫伤创面治疗传统手术和换药的方法,减轻医生工作量,极大地减少伤员疼痛和传统治疗副损伤。The moisture absorption sensor senses the humidity in the liquid suction chamber by attaching the flap to the liquid suction chamber formed under the medical film 10 on the outer skin surface of the patient's burn site, and the signal is fed back to the chip in the intelligent humidity control host 5 to control the humidity. The system, if it is detected that the humidity concentration in the liquid suction chamber exceeds a predetermined value, the vacuum pump works and provides suction power, and the liquid in the liquid suction chamber is sucked through the liquid storage bottle 4, the suction catheter 40, the drainage dressing layer 1 and the suction cup. Walking, the humidity in the aspiration chamber is maintained at a stable level of 80 to 90%. Thus.

The micro-vacuum environment not only helps the wound to reduce swelling, but also promotes the recovery of blood circulation disorders of the wound, improves the pathophysiological state of the "inter-ecological" shock cells, and saves the "inter-ecological" damaged tissues and cells as much as possible. In the stage of liquefaction and repair healing of necrotic tissue in burn wounds, the invention automatically controls the humidity of the wound surface, is beneficial to "dissolving" and releasing the necrotic tissue layer station, and through the adsorption chamber and vacuum pump suction, the dissolved necrotic tissue and The exudate draws away from the wound, reducing the likelihood of surgery such as “shaving” and “cutting”. The invention can promote local blood circulation by controlling the intermittent micro-vacuum in the adsorption cavity formed by the medical film 10 and the drainage auxiliary layer, and is beneficial to the residual dermis and skin attachment neoplastic epithelial cells and skin islands. In addition, because the fluid-dissolving tissue and wound exudate fluid resistance is small, it is easy to be removed by suction; while the neonatal epithelial cells and the skin island are integrated with normal tissues, it is not easy to be sucked off, and the vacuum suction is strong; Therefore, through the control of the intelligent humidity control host 5, the degree of vacuum of the appropriate size can be grasped clinically, and the wound can be achieved.
