一种防止腹腔穿刺孔漏气的密封套
By designing a funnel-shaped sealing sleeve, the fitting section fits snugly against the inner wall of the abdominal cavity, and the cannula section makes close contact with the trocar, thus solving the problem of poor sealing between the trocar and the puncture hole, achieving a highly efficient anti-leakage effect, and reducing the complexity and cost of operation.

AI Technical Summary
In existing technologies, the poor sealing between the puncture instrument and the puncture hole leads to leakage of gas from the abdominal cavity, resulting in subcutaneous emphysema, which increases the difficulty of treatment and the risk of complications.
A sealing sleeve comprising an adhesive section and a cannula section was designed. The adhesive section is funnel-shaped, and the cannula section is connected to the adhesive section and fitted onto the trocar. The adhesive section fits against the inner wall of the abdominal cavity, and the cannula section is in close contact with the trocar, forming a through channel to prevent gas leakage.
It effectively prevents air leakage from the puncture site, reduces operational difficulty and cost, improves sealing, and avoids the occurrence of subcutaneous emphysema.

Abstract
Claims
1. A sealing kit for preventing air leakage from a peritoneal puncture hole, characterized by comprising: The sealing sleeve is designed to be fitted onto a trocar. It includes an adhesive section and a cannula section. The adhesive section is funnel-shaped, and the cannula section is connected to the lower side of the adhesive section. A trocar channel is formed in the middle of the cannula section, which extends to the end away from the adhesive section and gradually decreases in cross-sectional area, so that the sealing sleeve can be detachably fitted onto the trocar. The adhesive section is fitted to the inner wall of the abdominal cavity.
2. The seal kit for preventing air leaks from a peritoneal dialysis catheter insertion site according to claim 1, wherein, The top surface of the bonding section is provided with a first annular groove along the circumferential direction.
3. The seal kit of claim 1, wherein, The top surface of the bonding section is a wavy, undulating curved surface.
4. The seal kit of claim 3, wherein, The wavy, undulating surface is arranged circumferentially or radially.
5. The seal kit of claim 1, wherein, The sealing sleeve is made of elastic material.
6. The seal kit of claim 1, wherein, The sidewall thickness of the bonding section gradually increases in the direction away from the sleeve section.
7. The seal kit of claim 1, wherein, At least one pair of pull rings are symmetrically arranged on the outer wall of the bonding section, and the pull rings are connected to the bonding section.
8. The seal kit of claim 1, wherein, The outer wall of the cannula section is provided with a second groove along the circumference, and a clamping member is provided in the second groove, which causes the inner diameter of the puncture device channel to shrink.
9. The sealing sleeve for preventing air leakage from the abdominal puncture hole according to claim 1, characterized in that, The inner wall of the fitting section and the sleeve section are connected by a rounded transition.
10. The seal kit of claim 1, wherein, It also includes a developing line, which is embedded in the sleeve section.
