[0024] The present invention will now be further described in detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. It should be noted that the words "front", "rear", "left" and "right" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] like Figure 1-6 As shown, a high-pressure infusion device includes a vertically arranged column 1 and a bracket plate 2, a pressure plate 3 and an infusion bag supporting plate 4 which are all arranged in parallel; wherein the bracket plate 2, the pressure plate 3 and the infusion bag supporting plate 4 are all quadrilateral plates and are arranged in sequence from top to bottom along the vertical line direction; one end of the column 1 is fixedly connected to the infusion bag supporting plate 4, and the other end is fixedly connected to the bracket plate 2; the pressure plate 3 is slidably arranged on the column 1, and is located between the bracket plate 2 and the infusion bag supporting plate 4.

[0026] A second elastic component 6 is arranged between the pressing plate 3 and the bracket plate 2, and a first elastic component 5 is sleeved on the column 1 between the pressing plate 3 and the bracket plate 2; specifically, the first elastic component 5 is a spring, which is sleeved on the column 1 and its two ends are respectively fixed to the pressing plate 3 and the bracket plate 2; the second elastic component 6 is a spring with the same length as the first elastic component 5 and a larger diameter, and its two ends are respectively fixed to the pressing plate 3 and the bracket plate 2; when the compressed first elastic component 5 and the second elastic component 6 are released, a thrust can be given to the pressing plate 3 to reduce the distance between the pressing plate 3 and the infusion bag supporting plate 4.

[0027] Preferably, in order to improve stability and realize balanced and uniform pressure, four columns 1 are provided, one end of each column 1 is respectively fixed to the four corners of the infusion bag supporting plate 4, and the other end is respectively fixed to the four corners of the bracket plate 2; the four corners of the pressing plate 3 are respectively sleeved on the four columns 1; correspondingly, four first elastic components 5 are also provided, respectively sleeved on the four columns 1. At the same time, the two ends of the second elastic component 6 are respectively arranged at the center of the pressing plate 3 and the bracket plate 2.

[0028] The column 1 is a three-section foldable linear column, including a first section 11, a second section 12 and a third section 13 pivotally connected in sequence from top to bottom; wherein the free end of the first section 11 is fixedly connected to the lower surface of the bracket plate 2; the free end of the third section 13 is fixedly connected to the upper surface of the infusion bag support plate 4.

[0029] Conventional locking mechanisms are respectively arranged between the first section 11 and the second section 12, and between the second section 12 and the third section 13 of the column 1 (e.g., the first section 11 and the second section 12, and the second section 12 and the third section 13 are respectively pivotally connected via a 90° limit axis), so that the column 1 can be folded to form a state where the first section 11 and the third section 13 are respectively 90° to the second section 12 and are respectively located on both sides thereof. Specifically, after the column 1 is folded, the second section 12 is in a horizontal state; the first section 11 is in a vertical state and is located on the upper side of the second section 12; the third section 13 is in a vertical state and is located on the lower side of the second section 12.

[0030] The length of the first section 11 is set to be smaller than the length of the first elastic component 5. After the column 1 is folded, the pressing plate 3 and the compressed first elastic component 5 will be restricted on the first section 11; when the column 1 is straightened, the first elastic component 5 is released and pushes the pressing plate 3 onto the second section 12, so that the distance between the pressing plate 3 and the infusion bag supporting plate 4 is reduced. It should be noted that by adjusting the length of the three sections of the column 1, the first elastic component 5 can also be released to push the pressing plate 3 onto the third section 13; it can be flexibly set according to actual conditions and needs.

[0031] The principle of use of this device: when not in use, lock the device; that is, fold the column 1 into a state in which the second section 12 is in a horizontal posture, the first section 11 and the third section 13 are in a vertical posture, and are respectively located on both sides of the second section 12; at this time, the pressure plate 3 and the compressed first elastic component 5 will be restricted on the first section 11, and the second elastic component 6 is also in a compressed state; when it is needed to be used, first straighten the second section 12 and the third section 13 to form a space for placing the infusion bag; after the connecting tube and other actions or equipment are installed and ready, straighten the first section 11 and the second section 12, release the first elastic component 5 and the second elastic component 6, and push the pressure plate 3 to pressurize the infusion bag, thereby achieving infusion.

[0032] In order to facilitate observation and reduce weight, the support plate 2, the pressing plate 3 and the infusion bag supporting plate 4 are all provided with hollow parts.

[0033] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
