摘 要:经过调研和观测当前的静脉输液过程,归纳出在输液装置上存在两方面问题:其一,输液过程需要人工监测,输液仪器不能自主检测输液液位并且及时停止输液进程,导致患者出现回血状况。其二,药液由于外界因素的影响,温度常常低于患者体温,这种情况下输液会使患者产生不适感,更甚会导致患者头昏乃至昏厥。为避免以上两种情况的发生,经过观察和分析整个静脉输液过程中护理人员和患者行为,运用系统设计方法针对以上情况设计一种新型的静脉输液装置,从而给患者带来安全并且舒适的输液体验。

Abstract :Through investigation and observation of the current process of intravenous infusion, summed up two aspects of problems about the infusion device: one is that the process need manual monitoring, infusion apparatus cant independent testing infusion liquid level and stop infusion process in a timely manner and lead to patients health status. Second, because of the impact of external factors the temperature of the liquid medicine is often lower than the patients body temperature, this kind of circumstance can make the patients produce discomfort, even more will lead to dizziness and fainting. To avoid the occurrence of the above two situations, through observation and analysis of the entire nursing staff and patients behavior in the process of intravenous infusion, in view of the above situation, to design a new type of intravenous transfusion device by a systematic design method, thus brings to the patient safety and comfort infusion experience.

靜脉输液作为医疗护理中的一种重要医疗手段,由于其药效快、刺激小、给药迅速从而在当今医疗机构中普遍使用。但是,现今的输液装置都或多或少存在不足,例如输液过程需要人工监测,输液仪器不能自主检测输液液位并且及时停止输液进程,从而导致患者出现回血状况。其次,药液由于外界因素的影响,温度常常低于患者体温,这种情况下输液会使致患者产生不适感,更甚会导致患者头昏乃至昏厥。本文所提出的新型输液装置综合了解决回血现象和药液温度过低现象的方法。
一、静脉输液中的常见情况分析
(一)静脉回血
静脉回血症状出现的原因:患者静脉压>输液管内压=回血
1.静脉输液时,造成回血现象的原因有多种,比较普遍原因是当输液瓶或输液袋的位置过低,血管内压力升高,体内的压强高于外界的大气压,产生了回血现象,因此要举高输液瓶或输液袋,使液体压强增大,从而将药液压入体内。
