Medical Infusion Device

Abstract

The invention discloses a medical infusion device which comprises a cuboid body, a first cavity, a second cavity, a rubber tube, an input opening, an output opening and an air inlet. The first cavity is formed in the upper portion of the cuboid body; the second cavity is formed in the lower portion of the cuboid body; the upper surface of the second cavity and the lower surface of the first cavity are located on the same plane; the volume of the second cavity is smaller than that of the first cavity. A round hole is formed in the upper surface of the second cavity, one end of the rubber tube is open, the other end of the rubber tube is closed, and a notch capable of being closed through self elasticity is formed in the side face of the rubber tube. The medical infusion device is used in cooperation with an existing infusion apparatus, liquid medicine flow speed in the whole infusion process can be stable.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical transfusion device. Background technique [0002] The medical infusion bottle is a bottle of liquid that is used for infusion in the human body when the patient is infused. The infusion set is a common disposable medical consumable that is used for intravenous infusion after aseptic treatment to establish a channel between the vein and the liquid medicine. Generally, it is composed of a venous needle, a protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip funnel, a cork puncturer, an air inlet pipe, and an air filter connection. Under the action of atmospheric pressure, the liquid in the infusion bottle flows into the drip funnel along the thinner infusion hose, and when the water column pressure in the drip funnel is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose.

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention: in the initial period of time in the existing infusion set, the liquid medicine tends to drip very quickly, which cannot be dripped at a uniform speed and is easy to bring discomfort to the patient's body; during the infusion process, sometimes the liquid medicine precipitates Objects can easily block the path of the air intake hole, and the air intake tube is set on the cork piercer. The air intake channel of the intake tube itself is very thin, and it is easy to cause the air to not be replenished in the infusion bottle through the intake tube in time, so that The pressure at the mouth of the infusion bottle changes greatly from time to time, so there will be a phenomenon that the liquid medicine cannot be dripped at a uniform speed and stably
