Abstract
Disclosed are: a system comprising a gas circulation device capable of circulating hyperthermic gas in the peritoneal cavity and a temperature control device; and a system comprising a drug spray device for effectively spraying a drug in the peritoneal cavity together with gas. The systems of the present invention are used as systems for hyperthermic intraperitoneal chemotherapy and can maximize the anticancer therapy effect by more effectively delivering a small amount of an anticancer drug to cancer cells while maintaining the temperature of gas in the peritoneal cavity at a predetermined temperature.
Claims18
A system for circulating hyperthermic pressurized gas in a peritoneal cavity, comprising:
- a gas circulation device that comprises a gas hose, which is configured to be connected to a peritoneal cavity of a subject, and a circulation pump which is connected to the gas hose and circulates gas discharged from the peritoneal cavity back to the peritoneal cavity;
- and
- a temperature control device that controls a gas temperature of the gas circulation device such that gas in the peritoneal cavity has a set temperature,
- wherein the gas circulation device comprises:
- an intraperitoneal gas injecting unit through which gas is injected into the peritoneal cavity;
- and a circulation unit which discharges gas from the peritoneal cavity, circulates the gas outside of the peritoneal cavity, and injects the gas back into the peritoneal cavity, and
- wherein the intraperitoneal gas injecting unit comprises a drug-and-gas spray device that sprays a drug together with gas during gas injection into the peritoneal cavity of the subject.
