Description

Safe infusion apparatus for pediatrics

Technical Field

The utility model relates to a paediatrics medical instrument's technical field specifically is a safe transfusion system is used to paediatrics.

Background

Traditional transfusion system is under atmospheric pressure effect, and liquid flows into the dropping funnel along thinner infusion hose in the bottle, and when dropping funnel water column pressure was greater than the venous pressure, the liquid in the bottle flowed into the vein along the hose, and when carrying out the infusion for children, because children self-control ability and expression ability are all relatively poor, moves about easily, in case the careless probably leads to the infusion can not normally go on in careless emergence of nurse personnel, takes place the phenomenon of returning blood even, leads to a large amount of blood losses.

A floating ball is arranged in a Murphy's dropper, when liquid enters the Murphy's dropper, the floating ball floats up to be separated from the lower end of the Murphy's dropper under the action of buoyancy, the liquid enters a scalp needle from the lower end of the Murphy's dropper through a rubber tube, and the whole infusion can be carried out. In the infusion process, the floating ball falls along with the liquid level in the tube, the lower end of the tube can be sealed by the floating ball falling, so that air is prevented from entering the lower rubber tube of the tube, at the moment, the liquid below the Murphy dropper stays in the rubber tube and cannot continue to drop into the blood tube, and the purpose of stopping infusion is achieved.
