[0043] The femoral artery cannula and the femoral vein cannula portable storage box according to the present disclosure will be described in further detail below in conjunction with the accompanying drawings and embodiments of the present disclosure.

[0044] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0045] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should also be understood that when the terms "comprise" and / or "include" are used in the specification, there is a presence of a feature, step, operation, device, component and / or combinations thereof.

[0046] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0047] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0048] like Figures 1-5 As shown, the portable storage box for femoral artery and femoral vein cannulas includes: a box body 1 primarily for storing the femoral artery and femoral vein cannulas, and a locking device 2 for fixing the femoral artery and femoral vein cannulas in a fixed position. The locking device 2 is fixedly connected inside the box body 1, so that the locking device 2 locks the femoral artery cannulas 01 and / or the femoral vein cannulas 02. One end of the femoral artery and femoral vein cannulas is locked inside the locking device 2, and the other end hangs down; during transportation, lifting one side of the locking device 2 allows the entire femoral artery and femoral vein cannulas to naturally hang down inside the box body 1.

[0049] During installation, the femoral artery cannula and femoral vein cannula will not be separated. Since the sealing bags of the femoral artery cannula and femoral vein cannula are wide enough, they can be sealed by the sealing bags after the buckle 2 is inserted.

[0050] Through the support of the box body 1, the accumulation between the adjacent femoral artery cannula and femoral vein cannula is avoided, and the femoral artery cannula and femoral vein cannula are crushed. By lifting the box body 1 on one side of the buckle 2, the bending of the femoral artery cannula and the femoral vein cannula is avoided, and the femoral artery cannula and the femoral vein cannula naturally hang inside the box body 1, which also avoids the bending of the femoral artery cannula and the femoral vein cannula, ensures the structure of the femoral artery cannula and the femoral vein cannula is not affected, and improves the use effect of the operation.
