Problems solved by technology

[0004] 1. Pollution may be caused when the injection liquid is pumped from the liquid bag into the high-pressure syringe, which is unsafe
[0005] 2. The high-pressure injection cylinder is a consumable, one-time use, and the cost of use is high, which increases the treatment cost for the patient
[0006] 3. The chemotherapeutic drugs and the solution cannot be heated together, so it is inevitable that some chemotherapeutic drugs will lose their stability
[0007] 4. In transcatheter interventional thermotherapy, heat exchange tubes are installed and heated in a water bath, and the temperature sensor is set at the outlet of the heat exchange tubes. However, due to the difference in ambient temperature and flow rate, the heat loss on the infusion line is difficult. Prediction makes it difficult to accurately control the temperature of the liquid medicine actually injected into the patient's body, and cannot achieve the best therapeutic effect
[0008] 5. In the hyperthermic perfusion chemotherapy of the thoracic and peritoneal cavity, the liquid storage bag is heated by microwaves, which may cause microwave pollution and may affect the performance of the drug
[0009] 6. For interventional thermotherapy for bladder tumors, it is necessary to control the intravesical pressure during treatment to be greater than the diastolic pressure of the patient, but there is no interventional thermotherapy machine dedicated to the treatment of bladder tumors

Abstract

The present invention is a tumor interventional thermal therapy machine with multiple functions, which is characterized in that a blocking perfusion loop is arranged. The blocking perfusion loop is a fluid-conveying pipe arranged between a storage liquid bag and an introduction tube. An introduction pump and a heating unit are arranged in series connection in the fluid-conveying pipe. The heating unit is a hot water bath groove. Middle section of the fluid-conveying pipe is a heat exchange tube arranged in the hot water bath groove. The present invention possesses advantages of reasonable structure, safe application, low application cost and reliable treatment effect. The present invention can realize multiple function therapies of ''thermal perfusion chemotherapy in target tumor artery through an artery catheter'', ''thermal perfusion chemotherapy in thoracoabdominal cavity'' and ''thermal perfusion chemotherapy in bladder'', respectively.

Description

technical field [0001] The present invention relates to a medical device, more specifically a tumor interventional hyperthermia machine, which is used for "target arterial thermochemotherapy" and "thermal coagulation" of various malignant solid tumors transarterial duct tumors, and for malignant pleural effusion and pleural effusion. "Thoracoabdominal hyperthermic chemotherapy" for abdominal malignant tumors, and "transcatheter hyperthermic chemotherapy" for bladder tumors.
