摘要临床上被动抬腿被广泛应用,但缺乏专用的机械抬腿设备,而是需要医护人员徒手抬腿或需要多功能床抬腿,既费时又费力,为此我们研制了一款新型的医用电动抬腿机.该设备具有以下特点:结构简单、性能稳定、操作简便、快速有效、安全舒适,升降结构的伸缩高度为50~120 cm,抬腿角度为10°~80°,支撑重量最大为40 kg.由于抬高下肢的高度及角度精准化,该设备能够完全代替传统人工徒手抬腿及多功能床的作用,减少医护人员体力及时间消耗;可随时更改设置满足患者的需求;可用于被动抬腿试验(PLR)以动态评估血流动力学;可以预防深静脉血栓形成,预防卧床相关并发症;且机器容易清洗消毒,能够有效避免院内感染及交叉感染,也可应用于各种灾害及突发事件的紧急救援.

abstractsPassive leg raising is widely used in clinic, but it lacks of specialized mechanical raise equipment. It requires medical staff to raise leg by hand or requires a multi-functional bed to raise leg, which takes time and effort. Therefore we have developed a new medical electric leg-raising machine. The equipment has the following characteristics: simple structure, stable performance, easy operation, fast and effective, safe and comfortable. The height range of the lifter is 50-120 cm, the range of the angle of raising leg is 10°-80°, the maximum supporting weight is 40 kg. Because of raising the height of the lower limbs and making precise angle, this equipment can completely replace the traditional manner of lifting leg by hand with multi-functional bed to lift patients' leg and can reduce the physical exhaustion and time consumption of medical staff. It can change the settings at any time to meet the needs of the patient;can be applied to the testing of PLR and dynamically assessing the hemodynamics; can prevent deep vein thrombosis and some related complications of staying in bed; and the machine is easy to be cleaned and disinfected, which can effectively avoid hospital acquired infection and cross infection; and can also be applied to emergency rescue of various disasters and emergencies.
