Description of the Related Art A portable and stationary tube welding apparatus using a high-frequency dielectric heating method is a pair of electrodes for sandwiching a tube and energizing and welding a high frequency, and a tube guide and an electrode for minimizing leakage of the high frequency. It is composed of a peripheral cover, a control unit, a high-frequency oscillation unit, and a power supply unit. Portable and stationary tube welding devices utilizing this high-frequency dielectric heating method are used in blood centers and hospitals for welding tubes of blood bags after blood collection. Recently, diseases such as post-transfusion hepatitis, AIDS, and ATL, which can be transmitted by blood transfusion, and G with extremely high mortality
Blood storage autologous blood transfusion has been increasing as a measure to prevent VHD and the like. 200ml or 400 for normal blood collection
After collecting the ml of blood, the blood collection needle is withdrawn from the donor, the tube is welded using a welding device near the needle, the needle portion is cut off from the tube, and the blood collection needle is discarded. However, in the case of blood storage type autologous blood transfusion, blood is usually collected from the patient several times in order to secure a sufficient transfusion volume, and the stored blood on the previous (time-wise) blood collection date is limited due to the restriction of the blood storage period. (One bag) is once returned to the patient, and twice as much blood (two bags) is collected and stored. At this time, an iron agent may be administered as a blood-supplying agent. Usually, at the time of storing the autologous blood, the blood sampling needle needs to be punctured only once (one needle) in order to reduce the physical burden on the patient, and the blood to be returned is placed in the blood collection tube connected to the punctured blood sampling needle. The blood collection tube of the blood bag and the line tube for administering the blood enhancer are joined using an aseptic joining device. At this time, the used line tube is sealed using a tube welding device.

Portable and stationary tube welding devices using the high-frequency dielectric heating method can be used with a blood collection needle punctured by a blood donor (or patient) when the blood collection needle is punctured. Blood donors may be electrocuted by leaked radio waves through sexual components. Therefore, the tube is clamped with a kochel, and the blood in the tube is cut off and insulated to prevent the leakage of electricity to the donor.
I can't say nothing. In addition, the portable and stationary tube welding devices using the high-frequency dielectric heating method emit radiation during high-frequency oscillation and float electrically (floating).
The conductive material in a state may be charged. That is, there is a risk that the kochel or the blood collection needle will be charged by the influence of the high frequency transmitted in the air, and the blood donor or the operator will receive an electric shock.
