新型引流管口换药贴的设计和应用

Design and application of a new type of medicine changing patch for drainage pipe orifice

在临床诊疗工作中,放置各类引流管目的是防止术后并发症或治疗部分外科疾患,如腹部外科术后放置的腹、盆腔引流管,胸外科术后放置的胸腔闭式引流管,以及软组织术后放置的负压吸引管等。放置引流管的目的均是将腹腔或胸腔内及皮下积液(包括血液、脓液、炎性渗液、胆汁等)引流到体外。在临床工作中,常遇到引流管口敷贴黏性不足、吸水性差等原因,导致引流管滑脱、引流管口渗液等,特别是渗液,使得引流管口周围皮肤受到引流液持续刺激,从而导致周围皮肤损伤、伤口愈合延迟、伤口感染风险增加等问题。为此,特设计了一种吸水性和黏性均良好的新型引流管口换药贴。该引流管口换药贴主要由黏贴层、防水层、竹炭纤维层和撕脱贴组成。与传统的引流管换药方式比较,应用新型引流管口换药贴的优势在于可稳妥黏贴于皮肤,避免滑落,且吸水性良好,从而避免渗液对皮肤产生长时间的刺激,降低伤口感染风险。为临床解决引流管渗液处理提供了一种很好的方案,值得推广。

In clinical diagnosis and treatment,the purpose of placing various drainage tubes is to prevent and treat postoperative complications or some surgical diseases,such as abdominal and pelvic drainage tubes placed after abdominal surgery,thoracic closed drainage tubes placed after thoracic surgery,negative pressure suction tubes placed after soft tissue surgery,etc.The purpose of the drainage tube is to drain the fluid(including blood,pus,inflammatory exudate,bile,etc.)in the abdominal cavity or chest cavity and the subcutaneous hydrops to the outside of the body.In clinical work,we often encounter the problems such as insufficient sticking and poor water absorption of the drainage pipe mouth,which cause the slippage and leakage of the drainage pipe mouth,especially the leakage,resulting in the skin around the drainage pipe mouth to be continuously stimulated by the drainage fluid and leading to the damage of the surrounding skin,the delay of wound healing,and the increased risk of wound infection.For this reason,we designed a new type of medicine changing patch with good water absorption and good viscosity.The dressing patch of the drainage pipe mouth is mainly composed of three parts:adhesive layer,waterproof layer and bamboo carbon fiber layer.Compared with the traditional way of dressing change,the advantage of the new-type dressing patch is that it can stick to the skin stably,avoid slipping,and has good water absorption in order to avoid the exudate stimulating on the skin for a long time and reduce the risk of wound infection.It provides a good scheme for clinical treatment of drainage tube leakage,which is worth to be popularized.
