Disposable automatic infusion device

Abstract

The invention provides a disposable automatic infusion device. The disposable automatic infusion device comprises a hanging rod, a first infusion bag, a second infusion bag, a third infusion bag and afourth infusion bag, wherein a connection rod is movably connected with the interior of the upper end of the hanging rod, a hook is fixedly connected with the upper end of the connection rod, a needle withdrawal reminding mechanism is arranged in the upper end of the hanging rod, hanging racks are fixedly connected with both the left side of the upper half portion and the right side of the lowerhalf portion of the hanging rod, the first infusion bag and the second infusion bag are connected with the left side of the upper half portion of the hanging rod through the corresponding hanging racks in a hung mode separately, and the third infusion bag and the fourth infusion bag are connected with the right side of the lower half portion of the hanging rod through the corresponding hanging racks in a hung mode separately. By connecting the first infusion bag, the second infusion bag, the third infusion bag and the fourth infusion bag in series through connection pipes, multiple bottles ofa liquid medicine can be administrated at a time in sequence, operation of liquid medicine change is not needed, the safety of automatic infusion is high, workload of nurses is greatly reduced, and the working efficiency of the medical workers is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable automatic infusion set. Background technique [0002] Disposable infusion set is a common disposable medical consumable that is mainly 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 pot, a cork puncturer, an air inlet pipe, and an air filter connection. Its working principle is that under the action of atmospheric pressure, the liquid in the bottle flows into the drip funnel along the thinner infusion hose. When the water column pressure of the drip funnel is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. [0003] However, there are the following disadvantages in the use of disposable infusion sets on the...
