the medical staff takes out the chemotherapy device 2, sends the catheter 21 into the esophagus of the patient, uses the cock 212 to assist and clean the sundries in the esophagus during the sending process, meanwhile, the position of the focus is determined by observing the picture shot by the micro camera 222 through the observation screen 14, so that the thermal therapy device 22 stays near the focus, the pulley 231 slides to determine the specific position and width of the thermal chemotherapy by adjusting the micro motor 232, then the gas-filled bottle 26 is opened to enable nitrogen to be conveyed into the sealed gas bags 23 along the nitrogen pipe 261, the two sealed gas bags 23 are filled with the nitrogen and then are contacted with the inner wall of the esophagus to form a treatment area in a section of the esophagus, then the adjusting valve of the conveying bottle 15 is opened to enable the medicine and the liquid medicine to be fully mixed and then enter the liquid medicine bottle 27, the medical staff rotates the rotating plate 25 in the operation hole 13 to enable the liquid medicine bottle 27 to be in butt joint with the liquid medicine pipe 271, and the liquid medicine is discharged from the liquid medicine port 272 through the liquid medicine pipe 271 and is filled into the treatment area;
then, the movable plate is rotated to the state shown in fig. 10 by operating the rotary motor 57, the ground thermotherapy medicine is conveyed into the second conveying pipe 12 along the feed openings 53 at both sides, the conveying bottle 15 corresponding to the second conveying pipe 12 is opened, a part of the thermotherapy liquid heated by the heating coil 31 enters the thermotherapy liquid bottle 28 through the first branch pipe 121, the rotary plate 25 is adjusted to make the thermotherapy liquid bottle 28 butted with the thermotherapy liquid pipe 281 on the fixed plate 24, then the thermotherapy liquid enters the liquid storage device 221 through the thermotherapy liquid pipe 281 to heat the liquid medicine in the treatment area, and another part of the thermotherapy liquid enters the steam patch 42 through the second branch pipe 122, after the thermotherapy liquid 43 on the steam patch 42 is butted with the thermotherapy device 22, the thermotherapy magnetic sheet starts to perform auxiliary thermotherapy on the corresponding part of the lesion outside the patient, and the heat insulation patch 41 performs heat insulation on the inside the chemotherapy mask 4;
when the temperature of the lesion detected on the temperature control device 223 is lower than 43 ℃, the heating coil 31 increases the working power to increase the temperature of the thermal therapy liquid, and when the temperature of the lesion detected on the temperature control device 223 is higher than 48 ℃, the heating coil 31 suspends the working to reduce the temperature of the thermal therapy liquid;
after the treatment is completed, the rotating plate 25 is rotated to adjust the liquid discharge bottle 29 to be in butt joint with the liquid discharge pipe 291, and the water pump 293 is turned on to draw out the liquid medicine and the waste liquid in the treatment area to the water tank 16.
Examples of the experiments
The feedback obtained by treating 500 patients by using the esophagus local thermal chemotherapy auxiliary dispensing device in the embodiment of the invention is compared with the conventional chemotherapy, and the result is shown in table 1:
TABLE 1 cure rate vs patient satisfaction
| Classification | Patient satisfaction% |
| Conventional chemotherapy | 65 |
| The invention | 88 |
Therefore, the satisfaction degree of 500 patients treated by the auxiliary dispensing device for esophagus local thermal chemotherapy is greatly improved compared with that of conventional chemotherapy, and the cure rate of the treatment by the auxiliary dispensing device for esophagus local thermal chemotherapy is improved to a certain degree compared with that of the conventional chemotherapy after a period of treatment.
