[0050] Detailed description of usage: When the device needs to be used to control the temperature of the replacement fluid, first pour the blood drawn from the patient's body into the mixing cylinder 301 with the help of the inlet tube 2. When the blood storage inside the mixing cylinder 301 is full, start the delivery pump inside the storage box to introduce the replacement fluid from the storage box into the temperature control cylinder 302. When the replacement fluid inside the temperature control cylinder 302 reaches the appropriate amount, operate the controller 305 to control the heating wire 307 to heat up with the help of the connecting line 308. The heat generated by the heating wire 307 will be transmitted from the inner cylinder 306 to the replacement fluid inside the temperature control cylinder 302. As the temperature of the replacement fluid gradually increases, the mercury level inside the glass tube 312 will gradually increase. When the temperature of the replacement fluid reaches the appropriate amount, the controller 305 will control the heating wire 307 to heat up with the help of the connecting line 308. The heat generated by the heating wire 307 will be transmitted from the inner cylinder 306 to the replacement fluid inside the temperature control cylinder 302. As the temperature of the replacement fluid gradually increases, the mercury level inside the glass tube 312 will gradually increase. After the replacement fluid is raised to a suitable temperature, the controller 305 will control the electric heating wire 307 to automatically cut off the power, and the mercury will cover the first wire 309 and the second wire 310. At this time, the controller 305 controls the servo motor 324 to start along the first wire 309 and the second wire 310. The servo motor 324 will drive the screw rod 319 to rotate, and the screw rod 319 drives the slider 320 to move upward along the inner wall of the slide rail 318. The slider 320 drives the sealing plate 321, so that the connecting hole 323 can be opened. At this time, the replacement fluid that has reached a suitable and stable state will flow into the mixing cylinder 301 along the temperature control cylinder 302, so that the replacement fluid and the inside of the mixing cylinder 301 can be mixed. The blood is mixed, and then the solenoid valve 7 is opened to allow the replacement fluid and blood to flow back into the human body. The above steps are repeated to continuously control the temperature of the replacement fluid. Among them, the adjusting rod 316 is rotated to drive the connecting plate 315 to move, and the connecting plate 315 drives the rubber sleeve 314 to move. The rubber sleeve 314 can simultaneously drive the first wire 309 and the second wire 310 to move along the inner wall of the glass tube 312, so that the replacement fluid can make the mercury rise to different heights in the glass tube 312 at different temperatures. The first wire 309 and the second wire 310 can be adjusted to contact the mercury, so that the sealing plate 321 can be opened in various situations. The adjusting rod 316 is rotated. In the process of driving the connecting plate 315 to move, the guide rod 317 can limit the rotation of the connecting plate 315, thereby preventing the connecting plate 315 from causing rotational deviation during the movement of the rubber sleeve 314. In addition, the one-way permeable membrane 325 can prevent blood from flowing back into the temperature control cylinder 302, thereby avoiding internal contamination of the temperature control cylinder 302. Finally, the scale 326 displays and indicates the current temperature value, allowing the user to accurately read the temperature value. By setting the temperature control device 3, the temperature of the replacement fluid can be automatically regulated to ensure that the replacement fluid is supercooled to avoid harm to the patient. Regulating the blood temperature through external technical means can effectively help alleviate or treat heat stroke.

[0051] When the replacement fluid needs to reach the mixing cylinder 301 and the blood and the replacement fluid need to be mixed quickly, the drive motor 405 is started to drive the driving gear 406 to rotate, the driving gear 406 drives the driven gear 407 to rotate, the driven gear 407 drives the rotating rod 403 to rotate, and the rotating rod 403 drives the stirring rod 404 to rotate, so that the stirring rod 404 can be rotated to stir and mix the blood and the replacement fluid inside the mixing cylinder 301. The motor is designed with a waterproof function and can operate normally in a humid or water environment without being damaged. By setting up the mixing device 4, the blood and the replacement fluid can be mixed quickly, thereby improving the practicality of the equipment.

[0052] When it is necessary to open the protective cover 505, first rotate the adjusting ring 509 to drive the rubber pad 510 to separate from the fixing seat 503, and then rotate the handle 506 to drive the protective cover 505 to separate the protective cover 505 from the protective box 501, so that the protective cover 505 can be opened. When it is necessary to close the protective cover 505 to protect the temperature control device 3, first move the handle 506 to drive the protective cover 505. During the rotation of the protective cover 505, it will drive the connecting plate 504 to rotate along the inner wall of the fixing seat 503. When the protective cover 505 is closed, rotate the adjusting ring 509 again to drive the rubber pad 510 to separate from the fixing seat 503. When the fixed seat 503 abuts, the protective cover 505 can be locked, thereby protecting the temperature control device 3. Among them, the rubber pad 510 can increase the friction of the adjustment ring 509 close to the fixed seat 503, so that the adjustment ring 509 can be firmly abutted against the fixed seat 503 with the help of the rubber pad 510. In addition, the movable handle 506 can drive the protective cover 505, thereby achieving the effect of convenient control of the protective cover 505. By setting up the protective device 5, the temperature control device 3 can be protected and covered, thereby avoiding damage to the temperature control device 3 caused by collisions, and improving the service life of the temperature control device 3.
