The inventive motion of the intravenous drip set “floating ball” apparatus is directed to the patient safety, decrease the medication loss, lower the cost of the medication and increase the efficacy of the nursing staff. The new creative function of this intravenous drip set “floating ball” apparatus is as follows:1. The “floating ball” will stuck to the opening of the drip set when the intravenous fluid dripped to the end, block the influx of air into the rubber tube of the drip set in order to prevent the life threatening air embolism to the patient it also create a small pressure in the rubber tube, preventing the reflux of blood to the catheter, causing clotting of the catheter, reduces the infection rate of the re-insertion of catheter, decreases the medication loss during discharge of air from the rubber tube.2. Decreases the pressure and panic of the patient’s family when the fluid dripped to the end and when the nursing staff unable to change the fluid on time.3. Increases the efficacy of nursing staff in caring patient, saving the time in dealing with the air in rubber tube and reflux of blood that causing clotting of the catheter and also to decrease the burden of the nursing staff.靜脈點滴輸液組套“浮力珠”裝置,發明動機係以病人安全為導向,並能降低藥品浪費節約藥品成本及提升護理人員工作效率之創意產品;此靜脈點滴輸液組套“浮力珠”裝置創新功能如下:1.當靜脈點滴輸液滴完時,此一“浮力珠”即會隨著輸液滴完而下降堵住輸液組套口,以防止空氣進入管路中,造成病人空氣栓塞,危及生命;並在管路內形成壓力,避免血液回流造成靜脈留置針阻塞,以降低重新注射感染的機率,及再次使用同一set時,因排氣而浪費的藥劑。2.降低病患家屬照顧壓力,不會因輸液滴完護理人員未及時更換輸液而恐慌。3.護理人員能更有效率的照護病患,不會浪費時間處理管路空氣及血液回流造成靜脈留置針阻塞,降低護理人員的負擔。
