Figure 5: Refer to the usage status reference diagram of this creation.

Referring to the first figure, the outer structure of the lid is opened and the second figure is shown. The lid is in the form of a closed structure.

The infusion device 10 of the present invention is composed of a structure such as a box body 11, a lid 12, an infusion set 13 and a liquid medicine bag 14; wherein the joint of the box body 11 and the lid 12 is joined by a hinge 110, and the lid 12 is away from the hinge One end of the 110 end is provided with a buckle 121, and one end of the buckle 121 has a buckle button 122 and The buckle 121 is connected, and the cover 12 is pressed downward, and the buckle 121 can be locked on the casing 11, so that the cover 12 is locked with the casing 11. The buckle button 122 is exposed on the outside of the cover 12, and the card is pressed. The button button 122 allows the lid 12 to be opened. The infusion set 13 is placed in the casing 11. As shown in the first figure, the needle 132 at one end of the infusion tube 131 of the infusion set 13 can be inserted into the human vein (as shown in the fifth figure) to inject the liquid medicine, and the infusion tube 131 The pin 133 at one end can engage the neck end 141 of the liquid medicine bag 14 in the casing 11, and the main feature is that the extrusion device of the present invention is a combination device of a plurality of air bags and a spring steel plate. .

As shown in the third figure, the upper portion of the lid 12 is mounted with an upper air bag 123, a middle air bag 124 and an upper pressing plate 125, wherein the upper surface of the upper air bag 123 is adhered to the lower surface of the upper pressing plate 125, The upper pressing plate 125 is provided with a plastic steel plate, and the upper and middle air bags 123 and 124 are connected by a tube at one end, and the inside thereof is filled with air and a sponge piece, and the gas systems are mutually unblocked.

Inside the casing 11, a lower air bag 111, a lower pressing plate 112, and a spring steel plate 113 are installed, wherein the lower air bag 111 is filled with air and a sponge piece, and the lower surface of the lower air bag 111 and the upper surface of the lower pressing plate 112 are provided. The lower end of the lower pressing plate 112 is provided with a spring steel plate 113, and a bearing 1131 is respectively disposed at both ends of the spring steel plate 113.
