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.

[0051] like Figures 1-6As shown, the venous ECMO tube puncture auxiliary device comprises: a front fixer 1 close to the venous ECMO tube puncture point; a rear fixer 2 away from one end of the venous ECMO tube puncture point; and a sealing bag 3 for sealing the venous ECMO tube between the front fixer 1 and the rear fixer 2. The front fixer 1 and the rear fixer 2 are sealed by the sealing bag 3, and the venous ECMO tube sequentially passes through the rear fixer 2, the sealing bag 3 and the front fixer 1.

[0052] During the venous ECMO tube puncture process, the front fixer 1 is released to clamp the venous ECMO tube, the rear fixer 2 clamps and pushes the venous ECMO tube, and the sealing bag 3 is folded, so that the venous ECMO tube slides along the front fixer 1 under the action of the rear fixer 2, thereby conveniently adjusting the puncture depth of the venous ECMO tube, conveniently adjusting the venous ECMO tube, and improving the puncture effect of the venous ECMO tube operation.

[0053] In order to meet the clamping and sealing effect of the front fixer 1 on the venous ECMO tube, the front fixer 1 comprises: a front fixing shell 11 providing clamping force and a front sealing member 12 providing pressure sealing effect on the venous ECMO tube, the front fixing shell 11 is connected to the front sealing member 12 at the center, and the venous ECMO tube passes through the center of the front sealing member 12.

[0054] In order to release the clamping of the front fixing shell 11 on the venous ECMO tube and ensure that the venous ECMO tube can slide relative to the front fixing shell 11 during puncture adjustment, thereby achieving the adjustment of the puncture depth of the venous ECMO tube, the front fixing shell 11 is provided with an opening slot 13, so that the front fixing shell 11 is divided into a left shell 111 and a right shell 112; the left shell 111 and the right shell 112 are locked and pressed to the front sealing member 12 at the opening slot 13 to press and seal the venous ECMO tube.

[0055] In order to conveniently meet the opening adjustment of the left shell 111 and the right shell 112 during the puncture process, the auxiliary device further comprises: a left pressing plate 113 connected to the right shell 112 and a right pressing plate 114 connected to the left shell 111, and the left pressing plate 113 and the right pressing plate 114 are pressed to drive the left shell 111 and the right shell 112 to open.

The flexible sealing bag 3 is sleeved on the outer wall of the front ring groove 14, so as to ensure the connection strength between the sealing bag 3 and the front sealing member 12. During the opening process of the front fixed shell 11, the sealing bag 3 is sleeved on the outer wall of the front sealing member 12 during the process of reducing the compression of the venous ECMO tube by the front sealing member 12, so as to ensure the sealing effect of the venous ECMO tube.

[0063] In order to seal the venous ECMO tube tightly by the rear fixer 2 in the puncture adjustment process. The rear fixer 2 is provided with a concave groove 23 on the side, so that the rear fixer 2 is divided into a left arc-shaped plate 21 and a right arc-shaped plate 22, and a rear sealing piece 24 is sealingly arranged between the left arc-shaped plate 21 and the right arc-shaped plate 22, and the venous ECMO tube passes through the center of the rear sealing piece 24. By pressing the left arc-shaped plate 21 and the right arc-shaped plate 22 close to each other, the venous ECMO tube can be pressed, and the position of the venous ECMO tube can be adjusted during the puncture operation. That is, the rear fixer 2 fixes the venous ECMO tube, the front fixer 1 loosens the venous ECMO tube, and the medical staff operates with both hands to insert or stretch out the venous ECMO tube from the patient's body, thereby improving the puncture effect, reducing the possibility of contamination of the venous ECMO tube, and improving the operation effect.
