The technical problem to be solved by the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a non-gravity infusion set that is relatively simple in structure, easy to use, and capable of infusion without suspension.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows: a non-gravity infusion device, which consists of a box body, a screw, two guide rods, a box cover, a liquid pushing plate, a stepping motor, a worm gear reducer, and a driving belt. Composed of pulley, synchronous belt, driven pulley and bag bottom pressing device, it is characterized in that: one end of the box body is provided with a convex hole, the stepping motor and worm gear reducer are installed above the box body, the driving belt The wheel and the worm gear reducer are connected by a flat key, the two guide rods and the screw axis are parallel to each other, and the liquid pushing plate is provided with two light holes and a threaded hole, and the two light holes are respectively connected with the two The root guide rod is connected, the threaded hole is connected with the screw rod, and the lower end surface of the liquid pushing plate is arc-shaped.

The bag bottom pressing device is used for pressing and fixing the bag bottom of the infusion bag, and the bag bottom pressing device is composed of a pressing rod, a supporting ear seat, a compression spring plate, a positioning guide rod, a positioning screw, a spring and a top pressing plate. Among them, the supporting ear seat is fixedly connected with the box body by welding, the pressure bar is U-shaped, and the middle part of both sides is provided with a long waist-shaped hole, and is connected with the supporting ear seat through a pin shaft, and the two sides of the pressing bar The end is connected with the compression spring plate through the pin shaft, the compression spring plate is fixed on the positioning guide rod by the positioning screw, and the top pressure plate is fixed on the box body by the screw.

When in use, start the stepping motor, the power of the stepping motor and worm gear reducer is transmitted to the screw through the driving pulley, synchronous belt and driven pulley, and the screw drives the liquid pushing plate to move and squeeze the infusion bag to achieve non-gravity Infusion. The speed of infusion is controlled by the rotation speed of the stepping motor.

The utility model can realize non-suspension liquid bag transfusion, is flexible and convenient to use, has controllable transfusion speed, and can avoid drug addition pollution. It is especially suitable for infusion in the process of transporting the wounded in wars, disasters, vehicles, ships and airplanes, and is not limited by infusion height and space.

The beneficial effects of the utility model are that the structure is relatively simple, the operation is convenient, the infusion speed can be controlled, and the infusion can be performed without suspension.
