Description
技术领域 technical field
本实用新型涉及一种医疗器具,具体是一种精确输血器。 The utility model relates to a medical device, in particular to a precise blood transfusion device.
背景技术 Background technique
目前,临床给患者输血时,采用的均为常规的输血器,包括插瓶针,穿刺针和墨菲滴管,大量输血时,由于血源不同,血型相同的血浆其 RH 因子不一定相同,所以,在挂完一袋血浆后,需要用盐水冲洗莫菲滴管,整个莫菲滴管冲洗完毕后,再接下一袋血浆,来回抽插容易造成污染且加大医护人员工作量;婴幼儿输血时,输入的血量较少,且需要非常精确,输血少则达不到治疗效果,输血过多则会加重其心脏负担,必须严格控制输血量;婴幼儿的血管较细,当血液中存在血小板、白细胞、纤维蛋白聚集的情况下,很有可能造成针头堵塞从而导致输血不畅。 At present, conventional blood transfusion sets are used for clinical blood transfusion to patients, including vial needles, puncture needles and Murphy droppers. During massive blood transfusions, due to different blood sources, plasma with the same blood type may not necessarily have the same RH factor. Therefore, after hanging a bag of plasma, it is necessary to rinse the Murphy dropper with saline. After the entire Murphy dropper is rinsed, the next bag of plasma is connected. Pulling and inserting back and forth will easily cause pollution and increase the workload of medical staff; When young children are transfused, the amount of blood transfused is small and needs to be very precise. Less blood transfusion will not achieve the therapeutic effect, and too much blood transfusion will increase the burden on the heart. The blood transfusion volume must be strictly controlled; infants and young children have thinner blood vessels. In the case of aggregation of platelets, white blood cells, and fibrin in blood, it is likely to cause needle blockage and lead to poor blood transfusion.
