Description
Technical field
This utility model relates to medical treatment and nursing instrument field, is specifically related to a kind of intravenous nutrition and supports metering transfusion system.
Background technology
In medical treatment and nursing, some critical patients can not or inconvenience oneself feed, for these patients, it is required for carrying out venous transfusion by nutrition infusion apparatus.
At present, commonly used single use nutrition transfusion bag carries out parenteral nutrition.Generally the disposable passages through which vital energy circulates nutrition infusion bag of Clinical practice, owing to general capacity is all 3000ml, therefore, is the most also commonly called as " three liters of bags ".It includes nutritional solution bag, water influent pipeline, infusion pipeline, water influent pipeline is typically provided two-way or three road feed tubes, being used for infusion liquid in transfusion bag, infusion pipeline includes dropping funnel, flow regulator, liquid medicine filter, joint and transfusion needle etc., transfusion catheter is cascaded through them.
Wherein, the material that nutritional solution bag typically uses is flexiplast, and the shape of nutritional solution bag is all planar as, and is propped up when filling nutritional solution, and when propping up, the shape of nutritional solution bag is irregular.Infusion amount or surplus for observation battalion's nutrient solution, all with scale on bag, but liquid non-regular shape in being because nutritional solution bag, be not equally distributed, can along with in bag the minimizing of nutritional solution and be continually changing, and when nutritional solution bag hangs, under gravity, below bag, the liquid of distribution is inevitable more, and scale can not accurately indicate surplus, it is also difficult to by liquid measure remaining in visual assessment bag.
It addition, some treatment is in order to reach more preferable effect, special transfusion pump can be used to control the speed of transfusion, infusion pump can also show flow velocity and flow simultaneously, but infusion pump price is high, apply very inconvenient, in ordinary nutritional transfusion nursing works, be difficult to popularization and application.Further, generally infused by infusion pump, inevitably produce actual flow velocity when nutrition infusion and setting flow velocity has error, thus the input quantity causing the amount of actually entering and infusion pump to show has error.As it was previously stated, the general capacity of nutritional solution bag is many, being often 3000ml, its input duration is long, up to 24 hours had, and takes care of the pence, and easily causes infusion fluid amount and there is relatively large deviation with actual patient required input.For needing the patient of strict restriction liquid input quantity, once beyond limiting liquid input quantity, or input quantity is not enough, is likely to cause serious consequence.
