Abstract

The invention provides an automatic liquid retention infusion apparatus, and belongs to the field of a medical article. The automatic liquid retention infusion apparatus comprises a regulator, a puncture needle, a Murphy's dropper, a first infusion tube, a liquid retention dropper, a second infusion tube, a filter, a capillary tube and a scalp needle, and is provided with a liquid retention regulating device for bending the connecting end of the first infusion tube, the liquid retention dropper tube and the second infusion tube into a U shape; the puncture needle, the Murphy's dropper, the first infusion tube, the liquid retention dropper, the second infusion tube, the filter, the capillary tube and the scalp needle are sequentially communicated; and the automatic liquid retention of the infusion apparatus and the infusion stopping are realized by using the liquid pressure balance principle at the two sides of the U-shaped tube. The automatic liquid retention infusion apparatus has the advantages that the structure is simple; the use is convenient; the practicability is high; and the automatic liquid retention infusion apparatus is applicable to clinic treatment.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to an automatic liquid retention infusion set. Background technique [0002] There are many types of infusion tubes on the market, such as multi-puncture needle infusion tubes, intelligent heating infusion tubes, etc. Infusion is based on the principle that the liquid pressure on one side of the infusion bag is higher than that on the side of the vein to inject saline or medicinal liquid into the vein. But after the infusion is completed, because the liquid in the infusion bag decreases and the volume increases, the pressure in the infusion tube will decrease and be lower than the pressure in the vein, causing blood to flow from the vein to the infusion tube. If the infusion tube is not pulled out in time, the blood will flow out from the vein into the capillary, and blood will return. When nurses and doctors are busy and have no time to take care of them, patients are always in a ...
