Infrared heat perfusion therapeutic apparatus

Abstract

An infrared heating perfusion apparatus for treating diseases features that the medicinal perfusion is indirectly heated by infrared heating tube, the temp measuring probe is used to measure the temp of perfusion, a hung weighing sensor is used to measure the dosage of perfusion, and an industrial control computer and the drivers of electromagntic valve, heater and peristaltic pump are used to control the heating time and circulated flow.

Description

technical field [0001] The invention relates to an infrared heat perfusion therapeutic apparatus, which is a warm liquid perfusion device based on infrared heating technology, and is used for combined treatment of heat and chemotherapy for prevention and treatment of recurrence and metastasis after resection of malignant tumors in the thoracoabdominal cavity. In the field of medical device technology, Background technique [0002] Taking serosa-positive gastrointestinal cancer as an example, even if curative radical resection is performed, most patients will die due to peritoneal recurrence and metastasis after surgery. The main reason is that there are free cancer cells and residual small cancer foci in the peritoneal cavity. These shed active cancer cell "seeds" may be planted in the "soil" provided by the surgical trauma and the exposed mesothelial connective tissue on the peritoneal surface, resulting in localized cancer. recurrence or metastasis. The clinical signific...

AI Technical Summary

Problems solved by technology

[0003] 1. The heat capacity of the system increases due to the exchange of the water bath box and the overall heating of the medicine bag, and the rapid temperature control is poor and prone to overshoot

[0004] 2. The temperature control accuracy and stability are not good, especially the real-time temperature adjustment cannot be realized

[0005] 3. The flow adjustment is imprecise, and it is difficult to ensure a constant perfusion dose in the thoracic and abdominal cavity

[0006] 4. Failure to provide the change curve of treatment parameters and temperature measured by important organs, which is not conducive to real-time monitoring

[0007] 5. The system is huge, the operation of conduit installation and replacement is complicated, and it is inconvenient to use
