Problems solved by technology

[0004] However, in the thoracic and abdominal drainage tubes currently used clinically, the drainage fluid cannot be recovered and is directly discarded. Repeated pumping of the fluid leads to a large amount of protein loss, resulting in hypoproteinemia in patients, and hypoproteinemia will further lead to thoracic and abdominal cavity drainage. Effusion, forming a vicious circle

Embodiment 1

[0045] figure 1 It is a structural schematic diagram of a pleural and peritoneal effusion tumor removal and drainage device provided in Embodiment 1 of the present invention. figure 2 It is a schematic structural diagram of the purification unit in the pleural and peritoneal effusion tumor removal and drainage device provided in Embodiment 1 of the present invention. Such as figure 1 and figure 2 As shown, the thoracic and peritoneal effusion tumor removal and drainage device provided in this embodiment includes an internal drainage tube 1, a liquid treatment assembly 2 and a return tube 3; the first end of the internal drainage tube 1 is used to extend into the human body through the puncture port 10 Inside, the second end of the inner drainage tube 1 protrudes from the puncture port 10, the inlet of the liquid treatment component 2 communicates with the second end of the inner drainage tube 1, and the outlet of the liquid treatment component 2 communicates with the first...

Embodiment 2

[0057] Since the effusion usually contains tumor cells, in order to improve the therapeutic effect on patients, the tumor cells in the effusion can be killed or inactivated when the effusion is taken out of the body. As an optional embodiment, the tumor cells in the effusion can be killed and inactivated by heating or other means. image 3 It is a schematic structural diagram of another pleural and peritoneal effusion tumor removal and drainage device provided in Embodiment 2 of the present invention. Such as image 3 As shown, wherein, the pleural and peritoneal effusion tumor removal and drainage device includes the structure of the internal drainage tube 1, the liquid treatment assembly 2 and the return tube 3 in the first embodiment, and the difference from the first embodiment is that this embodiment The liquid treatment assembly 2 in the example further includes a heating unit 22 , which is located between the inner drainage tube 1 and the purification unit 21 , and is ...

Embodiment 3

[0067] In order to further improve the treatment effect for patients, the pleural and peritoneal effusion tumor removal and drainage device can also be combined with drug treatment. Figure 4 It is a structural schematic diagram of another pleural and peritoneal effusion tumor removal and drainage device provided in Embodiment 3 of the present invention. Such as Figure 4 As shown, the thoracic and peritoneal effusion tumor removal and drainage device in this embodiment includes the structures of the internal drainage tube 1, the liquid treatment assembly 2, and the return tube 3 in the first embodiment, and is different from the first embodiment Yes, in the thoracic and peritoneal effusion tumor removal and drainage device in this embodiment, the liquid processing assembly 2 further includes a drug dosing unit 23, which is connected between the purification unit 21 and the return tube 3, and is used for dispensing the medicine ( For example, chemotherapy drugs cisplatin, car...

Abstract

The present invention provides a pleuroperitoneal cavity effusion tumor removal and drainage device. The pleuroperitoneal cavity effusion tumor removal and drainage device comprises an internal drainage pipe, a liquid treatment component and a return pipe; a first end of the internal drainage pipe is used for extending into human body through a puncture port, a second end of the internal drainagepipe extends out of the puncture port, an inlet of the liquid treatment component communicates with a second end of the internal drainage pipe, an outlet of the liquid treatment component communicateswith a first end of the return pipe, and a second end of the return pipe extends into human body; the liquid treatment component comprises a purification unit for filtering effusion flowing out of the human body; and the return pipe is used for inputting the filtered effusion into the human body again. The pleuroperitoneal cavity effusion tumor removal and drainage device can effectively remove tumor cells in the effusion.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for removing and draining pleural and peritoneal effusion tumors. Background technique [0002] Malignant pleural and peritoneal effusions are common complications of tumors and other diseases. Tumor cells in malignant pleural and peritoneal effusions have the ability to proliferate continuously and continue to break the barrier between the chest and peritoneum, resulting in continuous growth of pleural effusion and compression of organs. Severe complications such as water and electrolyte disorders and hypoproteinemia require a small amount of or multiple drainage, or local infusion of drugs. [0003] At present, the clinically used drainage method is usually to directly puncture the chest cavity or the abdominal cavity, and insert a drainage tube to drain the effusion in the chest cavity or the abdominal cavity out of the body. Specifically, the front end of the drainage...
