AI Technical Summary
In existing technologies, the surgical dressing placed suspended above the abdominal incision site during intraperitoneal hyperthermic perfusion chemotherapy poses problems such as drug leakage and high safety risks.
A patch for intraperitoneal hyperthermic perfusion chemotherapy was designed, including a sealing strip and a membrane body. The sealing strip is bonded to the periphery of the abdominal incision, the membrane body covers the incision, and a connecting tube is provided to connect to the negative pressure system of the operating room for aspirating chemotherapy drug vapors and liquids to reduce leakage.
It effectively prevents leakage of chemotherapy drug liquids and vapors, improves the safety and drug utilization rate of intraperitoneal hyperthermic perfusion chemotherapy, and reduces medical costs.

Abstract
Claims
1. A patch for hyperthermic intraperitoneal chemotherapy, characterized by, include: A sealing strip, the sealing strip being adapted to be installed on the inner circumference of an abdominal incision, and the sealing strip being adhered to the skin at the abdominal incision site, the two ends of the sealing strip abutting to form a ring; The membrane body is bonded to the sealing strip and covers the abdominal incision. The membrane body is provided with a first adhesive strip located on the outer periphery of the sealing strip. The membrane body is bonded to the operating table by the first adhesive strip.
2. The patch for intraperitoneal hyperthermic perfusion chemotherapy according to claim 1, wherein Also includes: A connecting tube capable of communicating with the negative pressure system of the operating room is installed at the edge of the abdominal incision and extends along the extension direction of the sealing strip. The connecting tube has multiple connecting ports arranged sequentially along its own extension direction to communicate with the patient's abdominal cavity, so as to discharge excess drug vapor in the patient's abdominal cavity and drug droplets formed by the condensation of drug vapor on the membrane body.
3. The patch for intraperitoneal hyperthermic perfusion chemotherapy according to claim 2, wherein The sealing strip is a breathable component, and the connecting tube is built into the sealing strip.
4. The patch for intraperitoneal hyperthermic perfusion chemotherapy according to claim 3, wherein The connecting tube is located on the side of the sealing strip closer to the membrane body.
5. The patch for hyperthermic intraperitoneal chemotherapy according to claim 2, wherein Also includes: An extension tube is provided, with its two ends connected to the connecting tube and the operating room negative pressure system, respectively. The membrane body is bonded to the extension tube via the first adhesive strip to fix the extension tube to the patient's abdomen.
6. The patch for intraperitoneal hyperthermic perfusion chemotherapy according to claim 1, wherein The sealing strip has a sealing groove that extends along the extension direction of the sealing strip, and the inner wall of the sealing groove is bonded to the skin at the abdominal incision site.
7. The patch for intraperitoneal hyperthermic perfusion chemotherapy according to claim 6, wherein The inner wall of the sealing groove is an arc shape that is recessed into the sealing strip.
8. The patch for intraperitoneal hyperthermic perfusion chemotherapy according to claim 1, wherein The membrane body is further provided with a shaping strip, which extends along the extension direction of the sealing strip. The shaping strip is located between the sealing strip and the first adhesive strip, and the shaping strip and the first adhesive strip are arranged at intervals. The shaping strip is configured to change its shape according to the shape of the surgical hook and the hyperthermic perfusion chemotherapy tube to support the membrane body, so that the first adhesive strip is respectively attached to the surgical hook and the hyperthermic perfusion chemotherapy tube.
9. The patch for intraperitoneal hyperthermic perfusion chemotherapy according to claim 1, wherein Also includes: The first adhesive strip includes a plurality of first adhesive strips arranged sequentially along the extension direction of the sealing strip. The coating is disposed on the side of the first adhesive strip away from the film body and is bonded to the first adhesive strip to protect the first adhesive strip.
10. The patch for intraperitoneal hyperthermic perfusion chemotherapy according to claim 1, wherein The membrane body has a pull ring on the side of the membrane body away from the sealing strip. The pull ring is located in the middle of the membrane body and is configured to move in a direction away from the sealing strip to lift the membrane body.
