分であった。[Background of the invention and its problems] A disease that lives in the blood! 111. For example, AfDs[! Conventionally, fever therapy has been used to treat cases of I. This raises the blood temperature and causes la'dl, but at this time the patient's physical strength was significantly exhausted and his condition worsened due to weakness. Also, when you have a fever, you don't have much blood.
Since the I temperature could not be increased, the sterilization effect was also insufficient.
［発明の目的］
この発明はこのような従来の問題点を解消すべく創案さ

得る殺菌方法を提供することを目的とする。[Object of the Invention] The present invention was devised to solve these conventional problems, and an object of the present invention is to provide a sterilization method that can effectively sterilize pathogens living in blood.
［発明の概要］
この発明に係る血液の殺２方法は、血液を一旦体外に取
出し、殺菌した後、再び体内に戻すものである。[Summary of the Invention] The blood killing method according to the present invention involves once taking blood out of the body, sterilizing it, and then returning it back into the body.
基づいて説明する。I will explain based on this.

を殺１室５に導き得る。The catheters 1.2 are each inserted into a blood vessel of the human body, and the pump 4 is a catheter 11I! Blood is aspirated from the catheter 1 and pumped through the blood chamber 5 to the catheter 2. The catheter 1 is inserted upstream of the blood vessel than the catheter 2, and forms a detour for the blood vessel. Therefore, blood can be led to the blood cell chamber 5 with almost no effect on the human body's blood clot.
第２（２は殺菌室の一例を示すものであり、殺菌室５は
、チューブ３が湾曲しつつ容器６内に収容されている。The second (2) shows an example of a sterilization chamber, and the sterilization chamber 5 is accommodated in a container 6 while the tube 3 is curved.

である。これによってチューブ３内を流れる血液は確実
に適正な温度まで加熱される。The container 6 is provided with a water supply lower and a drain port 8, through which water at a constant temperature is supplied and discharged. There is a stirring propeller 9 inside the container 6.
It is designed to stir the water inside the container and maintain a uniform temperature inside the container. A plurality of thermometers 10 are placed in the container 6.
are inserted and fixed, and the measured values of each thermometer 10 are input to the control computer 11. computer 11
starts or stops the supply of water from the water supply lower based on the data from the thermometer 10, and starts or stops the water supply from the water supply lower, and also starts the stirring propeller 3,
During cleaning, the propeller 9 converts kinetic energy into thermal energy through its zero rotation and raises the temperature of the water, so control of the propeller 9 is essential when strict temperature control is required. This ensures that the blood flowing through the tube 3 is heated to an appropriate temperature.
この加熱温度は殺菌すべき宿Ｗ菌に応じて２択すべきで
あり、かつ、血液組織を破壊しない温度とすべきである
。This heating temperature should be selected from two depending on the host W bacteria to be sterilized, and should be a temperature that does not destroy blood tissue.
このようにＩＩ接的に血液を加熱殺菌すれば人体にほと
んど負担を与えることがなく、殺菌効果は極めて高い。If blood is sterilized by heat in this way, it will cause almost no burden to the human body and the sterilization effect will be extremely high.

れ。FIG. 3 shows another example of a sterilization chamber, in which an ultraviolet run 112 is provided inside the container 6 to perform sterilization using ultraviolet light. The ultraviolet lamp 12 is covered with a hood 14.
このフード１４の移動により紫外線照射量が調節される
。By moving this hood 14, the amount of ultraviolet irradiation is adjusted.

接圧を制限する。17 is a roller 17.1 corresponding to the rotating shaft 15.15 which rotates synchronously so as to be symmetrical with respect to the tube 3.
7 is brought into contact with the tube 3 so as to sandwich the tube 3 between them, and is sent toward the sterilization chamber while crushing the tube 3. As the roller 17 moves, the contact pressure between the roller 17 and the tube 3 changes; Limit the contact pressure depending on the nature of the contact.
このようなポンプでは血液をポンプ機構に接触させるこ
