伤口快速闭合装置的研究

Development of Wound Quick Closing Device

复杂、巨大伤口的快速闭合是院前急救的关键步骤,可以有效减少院前患者的失血、失液量,对挽救患者生命有重要意义。该文研制了一种全新的伤口快速闭合装置,用于复杂、巨大伤口的快速闭合。首先,在对结构工作原理进行详细介绍的基础上,采用有限元仿真技术,对结构的受力情况进行了分析,结果表明结构受力后产生的应力没有超过材料的许用应力。在此基础上,进行离体伤口闭合实验。测试结果表明,该闭合装置操作时间为18.24 s,最小穿透皮肤的力为4.08 kg。该闭合器可抵抗1.53 kg水平拉力和2.25 kg的垂直拉力,封闭性良好,符合设计要求。结果表明该装置设计合理,可以快速、有效地实现伤口的闭合。

Complex and huge wound closure is a key step reduce the loss of blood and fluid inpatients before n pre hospital emergency care. Wound closure can effectively arriving hospital. Also, it has important significance to save the lives of patients. In this paper, a new type of wound closure device is developed, which is used for the rapid closure of complex and huge wound. Firstly, based on the detailed introduction of the structure working principle, the finite element simulation technology is adopted to analyze the stress of the structure. The results show that the stress of the structure has not beyond the allowable stress of the material. On the basis of this, the experiment was carried out in vitro. Test results show that the closure device operating time is 18.24 s and the minimum penetration of the skin force is 4.08 kg. The closure device can resist the horizontal tension of 1.53 kg and vertical tension of 2.25 kg. It also has good sealing performance and meets the design requirements. The results show that the device designed is reasonable, which can be quickly and effectively to achieve closure of the wound.
