Description

Transfusion head and automatic decanting transfusion system
Technical field
This utility model relates to medical equipment, particularly relates to transfusion head and automatic decanting transfusion system.
Background technology
Transfusion has another name called has an intravenous drip or hangs water, is inputted internal large bolus injection liquid by intravenous drip, is packaged in infusion bottle or transfusion bag. During use, drip speed by transfusion device adjustment, continue and stably enter vein, with supplementary body fluid, electrolyte or offer nutrient substance. Hospital is when infusing to patient, generally require the situation collocation according to patient and use many bottles or many bags transfusions, this is accomplished by patient or the family numbers of patients moment pays close attention to transfusion condition, to notify that nurse changes bottle in time, causing that nurse changes the workload of bottle very big, patient or family numbers of patients can not well be had a rest. Therefore, automatic decanting technology becomes the focus of people's research.
Although electronic intelligence controls module can solve the problem that the problem of automatic decanting, but price is high, technology is also not mature enough, and reliability is not high, it is also inconvenient to use.
The device of automatic decanting is controlled, although also be able to solve the problem of automatic decanting, but ball float material selects difficulty, need to select the material that relative density is much smaller than 1 and security performance is high, or be processed into hollow float, considerably increase difficulty of processing by ball float.
