摘　　要：目的自制袋装输液加压装置并研究其在临床治疗中的应用价值。方法本装置由输液袋套、拉链、橡胶增压气囊、充气阀门和充气皮球等部分组成,通过充气皮球向橡胶增压气囊中充气,达到加压输液目的。经过压力检测装置进行加压实验,研究了气囊压力和输液速度间的关系,确定补充加压的间隔时间。结果不同初始滴速下,随着橡胶气囊压力增大,输液滴速也随之增大。输液速度在160～200mmHg变化幅度较大,≥220mmHg时滴速增幅微小。随着输液袋中液体的减少,气囊压力也随之下降,输液滴速也会逐渐下降。输液速度从130滴/min下降到85滴/min约需15min,从130滴/min下降到100滴/min约需11min。如需将滴速维持在100滴/min以上,故增补气囊压力频次应为1次/10min。临床实际应用表明,在感染性休克和消化道出血的抢救中,该装置确能达到加快输液速度、缩短补充有效循环血量的时间、提高抢救成功率的作用。结论本文自行研制的袋装输液加压装置具有明显的加压输液功效,具有减少液体污染、节约人力成本、减轻护士工作量等特点,有良好的应用前景。Objective To design a pressure infusion devices for bagged-liquid and discuss its clinical application value.Methods The device consists of the infusion bag,zipper,rubber closed airbags,valve switch,inflatable rubber ball and other components.By extruding rubber ball to enhance the air bag pressure to achieve the purpose of pressure infusion.Then the relationship between the infusion speed and the airbag pressure was studied by a pressure detection device.And the interval time period was determined for adding the airbag pressure.Results Under different initial drip rate,when the rubber air bag pressure increased,the infusion drip rate increased.When the initial airbag pressure in the range of 160-200 mm Hg,the infusion rate became higher while the pressure was getting higher.When the airbag pressure were greater than or equal to 220 mm Hg,the infusion speed changed slightly.The reduction of the infusion bag liquid could result in the airbag pressure decreasing,and then the infusion drip rate declined gradually.About 15 minutes was needed for the infusion rate decreased from 130 drops/min to 85 drops/min,while 11 minutes from 130 drops/min to 100 drops/min.For maintaining the infusion rate at 100 drop/min above,the frequency to readd the airbag pressure should be 10 minutes interval.Clinical practice showed that this device could effectively speed up the infusion rate,shorten the time to recover the circulating blood volume and improve the survival rate of the patients with infectious shock or upper gastrointestinal bleeding.Conclusions This self-developed semi-automatic pressure infusion device is helpful to increase the infusion rate and reduce the pollution,save the labor costs,reduce the workload of nurses,which has a good prospect of clinical application.
