慢性创面已成为我国体表创面的主要形式
● 病因复杂，往往由各种慢性病引起
● 老年患者居多，严重影响患者晚年生活质量
● 患者家庭负担大：治疗周期长、愈合难，亲属看护压力大
我国每年有3000万慢性难愈合创面。
我国糖尿病患者1.14亿。
糖尿病足溃疡是糖尿病常
见的并发症之一。预计
15-20%的糖尿病患者
最终会患糖尿病足溃疡。
大部分慢性创面患者会前
往医院就诊。但是有约
20-30%的慢性创面患
者会长期居家卧床。这其
中以农村空巢老人的压疮
问题最为严重。
2018我国60岁以上老人
已达2.41亿。

NPWT至今已在全球治疗服务患者超过1000万，对于各类急慢性伤口，由海内外各伤口治疗组织或
协会，发布了针对不同类型伤口的NPWT临床论文超过3000份，包括得到广受认可的治疗指南或共识文
献等。NPWT治疗各种急慢性伤口的疗效及价值，在全球范围内已广为认可。

NPWT（Negative Pressure Wound Therapy 负压伤口治疗）是上世纪90年代以来发展起来的关于伤口治疗的新技术。自被引入临床实践以来，负压伤口治疗已广泛应用于门诊和住院中复杂伤口的管理*1。
NPWT被认为是许多不同病因的伤口的有效治疗方案*2,3，并被推荐作为治疗创面的金标准-如开放式腹部伤口*4-6，心脏手术后的开裂胸骨伤口*7,8等，以及各种复杂难愈合创面*9,10中的有价值的治疗方案。越来越多的NPWT被应用在居家伤口管理中，其被认为在提升伤口管理效果方面具有巨大潜力，有助于减少对医院护理的依赖*11。
