Description

Transfusion system

Technical Field

The application relates to the field of medical appliances, in particular to an infusion apparatus.

Background

A disposable infusion set is a common medical consumable, and a channel between a vein and liquid medicine is established through aseptic treatment and is used for intravenous infusion. Generally, the infusion apparatus is formed by connecting eight parts, namely a vein needle or an injection needle, a needle head protective cap, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip cup, a bottle stopper puncture outfit, an air filter and the like, and a part of the infusion apparatus also comprises an injection piece, a medicine adding port and the like.

In the related technology, the infusion apparatus and the air filter are separately arranged, an infusion tube and a vent tube are arranged, and bottle stopper puncture outfits are arranged on the infusion apparatus and the air supply filter. When in use, the air filter and the infusion apparatus are respectively inserted into the bottle cork of the liquid medicine bottle.

In the infusion process, if the infusion tube needle inserted into the infusion bottle stopper is opposite to the inclined plane of the vent tube needle, the distance is relatively short, and the position of the vent tube needle is slightly lower than that of the infusion tube needle, the suction force generated by the flow rate of liquid in the infusion tube can suck the bubbles generated by the vent tube needle into the infusion tube. And the closer the two needle bevels are, the faster the liquid flows and the more gas is sucked into the infusion tube. In addition, the needle inserted into the stopper of the infusion bottle has poor stability, and if the infusion tube is influenced by external force such as movement of the patient body during infusion, the needle of the infusion tube connected with the infusion tube can correspondingly move in direction and position. If the two needles are in the air-inletting positions, air can enter the infusion tube from the needle of the infusion tube. If the treatment is not timely, air embolism can occur, and the life of the patient is threatened.

In view of the above-mentioned related art, the inventors have considered that it is necessary to prevent the start of infusion and the intake of air from above the infusion tube during the infusion.
