Embodiment 1

[0025] Such as image 3 As shown, a perfusion type tumor hyperthermia apparatus of the present invention includes a liquid medicine tank 3, and the liquid medicine tank 3 is respectively connected with a perfusion conduit 99 and a return conduit 88, and the liquid medicine tank 3 is also connected with a return conduit 88. A weighing sensor 7 is connected, and an output valve 4, a perfusion pump 9, an infrared heater 10, a first temperature sensor 1 and a perfusion valve 11 are sequentially arranged on the perfusion conduit 99, and an output valve 4, a perfusion pump 9, an infrared heater 10, a first temperature sensor 1, and a perfusion valve 11 are sequentially arranged on the described return conduit 88. There is a reflux pump 8 , a second temperature sensor 2 and a reflux valve 111 . The end of the perfusion conduit 99 is provided with a perfusion connection pipe 113 , and the end of the return pipe 88 is provided with a recirculation connection pipe 112 .

Embodiment 2

[0030] Such as figure 1 As shown, the present invention also provides a protection method for realizing the treatment temperature in the safety protection method of the above-mentioned perfusion type tumor thermotherapy apparatus, and the specific steps of the protection method are:

[0031] 11. After starting the thermoperfusion therapy, collect the treatment temperature through the temperature sensors 1 and 2;

[0032] 12. Carry out a conditional judgment on the collected temperature, if the temperature is lower than 5 degrees Celsius, it means that the temperature sensor 1 and 2 are invalid, then go to the termination of treatment 16, if not established, then go to step 13;

[0033] 13. In the perfusion and treatment stage, conditional judgment is performed on the collected temperature, if it exceeds the maximum treatment temperature, go to stop treatment 16, if not, go to step 14;

[0034] 14. In the perfusion and treatment phase, conditional judgment is performed on ...

Embodiment 3

[0054] After starting the instrument to start treatment, if the following faults occur, the method of the present invention can automatically identify and protect them:

[0055] 1. Temperature sensor out of control (open circuit)

[0056] During the operation of the instrument, if the temperature sensors 1 and 2 are out of control (open circuit), the measured temperature will be lower than 5 degrees Celsius, and if it meets step 12 of this method, then turn off the signal 6 of the infrared heater 10 and the signal 41 of the perfusion pump And the return pump signal 42, stop the treatment to protect the patient.

[0057] 2. heater out of control

[0058] During the perfusion or treatment stage, the heater 10 is out of control. If the heater 10 continues to heat, the temperature measured at the perfusion trident tube 31 will exceed 53 degrees Celsius, which meets step 13 of the method; if the heater 10 cannot be heated, At this time, if the temperature at the place of the po...

Abstract

The invention belongs to the technical field of biological engineering, and provides a perfusion tumor thermal therapy instrument, which is used for solving the technical problem of potential safety hazard occurring easily in the treatment process of the perfusion tumor thermal therapy instrument. The perfusion tumor thermal therapy instrument comprises a liquid medicament tank, wherein the liquid medicament tank is connected with a perfusion conduit and a reflux conduit respectively; the liquid medicament tank is further connected with a weighing sensor; the perfusion conduit is provided with an output valve, a perfusion pump, an infrared heater, a first temperature sensor and a perfusion valve in sequence; the reflux conduit is provided with a reflux pump, a second temperature sensor and a reflux valve in sequence; the tail end of the perfusion conduit is provided with a perfusion connecting tube; and the tail end of the reflux tube is provided with a reflux connecting tube. The invention further provides a method for realizing safety protection of the perfusion tumor thermal therapy instrument. The treatment temperature and the residual quantity of a liquid medicament are monitored in real time during thermal perfusion treatment, so that problems easily occurring in the treatment process can be judged, and treatment is stopped immediately once a certain problem is judged to prevent hurting patients or operating personnel.

Description

technical field [0001] The invention belongs to the field of biomedical engineering, and in particular relates to a medical device, especially a perfusion type tumor thermotherapy instrument and a method for realizing safety protection. Background technique [0002] Tumor hyperthermia refers to a kind of treatment method that uses heat to treat tumors. The basic principle is to use physical energy to heat the whole body or part of the human body, so that the temperature of tumor tissue rises to the effective therapeutic temperature and maintain it for a certain period of time. Using the difference in temperature tolerance between normal tissue and tumor cells, it can achieve both tumor cell apoptosis and The purpose of treatment without damaging normal tissue. Tumor hyperthermia has become the fifth major therapy after surgery, radiotherapy, chemotherapy and immunotherapy, and it is a new and effective means of treating tumors. [0003] In the process of tumor hyperthermia...
