Infusion device capable of effectively avoiding gas from entering tubeline

Abstract

The invention relates to a transfusion device capable of effectively preventing gas from entering into a pipeline at the beginning of transfusion and in the transfusion process, which belongs to the technical field of disposable medical devices. The transfusion device is characterized in that a hollow variable flow pipe with a closed top end and an opening on the lateral wall is additionally arranged inside an outlet end of a dropping funnel; when a stabber of the transfusion device is inserted in a transfusion bottle or a transfusion bag, the dropping funnel is reversed and extruded to be filled with liquor; when the dropping funnel stands positively, the liquor flowing out from the dropping funnel can not directly impact an outlet at the bottom of the dropping funnel due to the barrier of the top of the variable flow pipe and can flow into the pipeline of the transfusion device from the opening on the lateral surface of the variable flow pipe, so as to achieve the purpose for preventing liquor and gas from entering into the pipeline together.

Description

Technical field [0001] The invention relates to an infusion set which effectively prevents gas from entering pipelines at the beginning and during the infusion, and belongs to the technical field of disposable medical devices. Background technique [0002] The conventional infusion set is inserted into the infusion bottle or infusion bag through the puncture device, turned upside down and squeezed to fill the dripping funnel. When the dripping funnel is upright, the liquid flowing out of the dripping tube directly hits the outlet at the bottom of the dripping funnel due to the fast liquid flow, causing The liquid medicine enters the pipeline together with the gas. After the flow rate stabilizes, the gas adheres to the wall of the infusion pipeline in the form of bubbles, which brings safety hazards to the infusion patients and inconveniences the medical staff to remove the bubbles. Contents of the invention [0003] In order to solve the problem of air bubbles in the pipel...
