For example, the relative terms will at least include the degree of error associated with measuring the particular quantity by the particular measuring instrument, tolerance in the manufacturing, assembly, use, etc. of the particular quantity. Such terms should also be considered as disclosing a range that is defined by the absolute values of the two endpoints. The relative terms can refer to a percentage (e.g., 1%, 5%, 10% or more) of the indicated value plus or minus. Values that are not preceded by a relative term should also be disclosed as specific values with tolerances. In addition, "substantially" when used in expressing a relative angular positional relationship (e.g., substantially parallel, substantially perpendicular) can refer to plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0037] In this application, those of ordinary skill in the art will appreciate that a function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, a function performed by a part can be performed by one part, one component, or multiple parts in combination.

[0038] In this application, the terms "upper," "lower," "left," "right," "front," "back," and the like describe the orientation and position as shown in the figures and are not meant to be limiting.

[0039] As Figure 1As shown, the embodiment provides an endoscopic perfusion automatic pressurization device, which comprises a gas storage bag 100, an inflation ball 200 and a gas pump 300. The gas storage bag 100 has a gas bag and a containing cavity for containing a liquid bag 1000. The inflation ball 200 has an inflation cavity, an inflation inlet and an inflation outlet communicating with the inflation cavity, and the gas bag communicates with the inflation outlet. The gas pump 300 is detachably connected with the inflation ball 200, and the gas outlet of the gas pump 300 communicates with the inflation inlet. The gas pump 300 is used to make external gas flow through the inflation ball 200 and enter the gas bag to extrude the liquid bag 1000 in the containing cavity.
