人工推注高浓度葡萄糖或甘露醇等药液,操作强度高,护理人员容易疲劳。为此,我们根据丝杆原理自制了一台静脉助推器。该助推器结主要由托架、固定杆、丝杆、缓进器、摇轮和摇把组成. Manual bolus injection of high concentrations of glucose or mannitol and other liquid, high intensity, nurses fatigue. For this reason, we made a venous booster according to the screw principle. The booster knot is mainly composed of a bracket, a fixed rod, a screw rod, a buffer, a rocker and a crank.
