Description

Infusion apparatus capable of preventing air from entering human body and preventing blood from returning due to empty liquid

Technical Field

The utility model relates to a transfusion apparatus technical field, more specifically the transfusion system who avoids empty air admission human and prevent blood return of leading to of liquid stream that says so.

Background

The infusion apparatus is a common medical consumable, and a channel between a vein and liquid medicine is established through aseptic treatment for intravenous infusion. Generally comprises eight parts of a vein needle or an injection needle, a needle head protective cap, a transfusion hose, a liquid medicine filter, a flow rate regulator, a dropping funnel, a bottle stopper puncture outfit, an air filter and the like which are connected. Under the action of atmospheric pressure, the liquid in the bottle flows into the dropping funnel along the thin infusion hose, and when the pressure of the water column of the dropping funnel is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose.

However, when the existing infusion apparatus is used, a patient or a family member must pay attention to the amount of liquid medicine in the infusion bottle all the time, when the liquid medicine in the infusion bottle is about to end, a medical worker needs to be immediately informed to pull out a needle or replace the liquid medicine, if a doctor and a patient cannot find the liquid medicine in time, blood is easy to flow back from the tail end of the infusion apparatus, various medical accidents such as bacterial infection, septicemia and the like are caused, and the personal safety of the patient is damaged.

Therefore, it is an urgent need to solve the problem of providing a safe infusion apparatus that can prevent air from entering human body due to empty liquid and prevent blood return.
