Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

Example 1:

referring to fig. 1, the embodiment provides a wobble film 200 suitable for a puncture sealing assembly, and the wobble film 200 includes a first base 201, a second base 202, and an S-shaped connecting portion 203 disposed between the first base 201 and the second base 202. The S-shaped connecting portion 203 includes a small U-shaped folded portion 2031 connected to the first base 201, and a large U-shaped folded portion 2032 connected to the second base 202; wherein the small U-shaped folded portion 2031 and the large U-shaped folded portion 2032 share a side wall; the small U-shaped folded portion 2031 protrudes from the first base 201, the large U-shaped folded portion 2032 protrudes from the second base 202, and the protruding direction of the small U-shaped folded portion 2031 with respect to the first base 201 is opposite to the protruding direction of the large U-shaped folded portion 2032 with respect to the second base 202. For the oscillating membrane 200 of the present embodiment, a material with a certain elasticity is adopted, such as but not limited to medical polymer plastic, such as medical polytetrafluoroethylene, or rubber or silica gel, so that the elastic material is matched with the S-shaped connecting portion 203 to jointly realize that the oscillating membrane 200 exhibits good following performance along with the movement of the puncture needle rod.

When the wobble film 200 of the present embodiment is applied to a puncture sealing assembly, the first abutment 201 is adapted to be coupled to other structures of the puncture sealing assembly, and the second abutment 202 is adapted to be coupled to the cannula cover 1 of the puncture device. Here, in the case where the direction in which the small U-shaped folded portion 2031 protrudes relative to the first abutment 201 is opposite to the direction in which the large U-shaped folded portion 2032 protrudes relative to the second abutment 202, it is an alternative that the small U-shaped folded portion 2031 protrudes relative to the first abutment 201 toward the cannula cover 1 side of the puncture instrument, and the large U-shaped folded portion 2032 protrudes relative to the first abutment 201 away from the cannula cover 1 side of the puncture instrument; in a further alternative case, the small U-shaped folding portion 2031 protrudes from the first base 201 toward the cannula cover 1 side of the puncture instrument, and the large U-shaped folding portion 2032 protrudes from the first base 201 toward the cannula cover 1 side of the puncture instrument, in this case, in the present embodiment, in this case, theoretically, the distortion of the S-shaped connection portion 203 formed by the small U-shaped folding portion 2031 and the large U-shaped folding portion 2032 is affected by the height of the small U-shaped folding portion 2031 protruding from the first base 201 and the height of the large U-shaped folding portion 2032 protruding from the second base 202, that is, the larger the height of the protrusion is, the larger the space for distortion of the S-shaped connection portion 203 is. However, since the side of the cannula cover 1 away from the puncture device, that is, the side of the fisheye valve 100, and the fisheye valve 100 are mainly formed with good followability in the movement process of the puncture needle rod, and good sealing performance is also considered, it is necessary that the swing film 200 included in the puncture sealing assembly formed together with the fisheye valve 100 has good followability, that is, the side of the cannula cover 1 away from the puncture device from the first base 201 is a movement interval in which the fisheye valve 100 drives the whole puncture sealing assembly to move along with the puncture needle rod, and here, considering the influence of reducing the protrusion height of the small U-shaped folding portion 2031 relative to the first base 201 on the movement of the whole puncture sealing assembly driven by the fisheye valve 100 along with the puncture needle rod on the premise of effectively ensuring the distortion space of the S-shaped connecting portion 203, the height of the small U-shaped folded portion 2031 projected from the first base 201 is smaller than the height of the large U-shaped folded portion 2032 projected from the second base 202. Namely, the height of the protrusion of the large U-shaped folding portion 2032 towards the cannula cover 1 side of the puncture device is fully utilized to provide a relatively large distortion space for the S-shaped connecting portion 203, and the protrusion height of the small U-shaped folding portion 2031 relative to the first base 201 is controlled to provide the distortion space for the S-shaped connecting portion 203 and simultaneously reduce the influence on the integral following of the fish-eye valve 100 and the puncture sealing assembly relative to the puncture needle rod.

Further, as for the distortion of the S-shaped connecting portion 203, in addition to the influence of the height of the protrusion of the small U-shaped folded portion 2031 with respect to the first base 201 and the height of the protrusion of the large U-shaped folded portion 2032 with respect to the second base 202, the influence of the magnitude of the distance between the two side walls of the small U-shaped folded portion 2031 and the distance between the two side walls of the large U-shaped folded portion 2032 may be the same or different, for example, by designing the distance between the two side walls of the small U-shaped folded portion 2031 to be larger than the distance between the two side walls of the large U-shaped folded portion 2032 to compensate for the height of the protrusion of the small U-shaped folded portion 2031 with respect to the first base 201 being smaller than the height of the protrusion of the large U-shaped folded portion 2032 with respect to the second base 203202, this improves the contribution of the small U-shaped folded portion 2031 to the distortion of the S-shaped connecting portion 203.
