Piston 9, the cavity below the first piston 9 in the second shell 8 is filled with expanding liquid, the inner top surface of the second shell 8 is provided with a first air hole 11, and the top surface of the first shell 2 corresponds to the first air hole 11. A second air hole 12 is opened at the position of an air hole 11, a support frame 13 is installed on the top surface of the first housing 2, and a first laser range finder 14 is installed on the support frame 13. The first laser range finder 14 is used for measuring The height of the first piston 9, the right side of the first housing 2 is provided with a third housing 15, the left top of the third housing 15 is provided with a third through hole 18, the third through hole 18 and the second through hole 6 communicate with each other through a connecting pipe 16, and a temperature regulating mechanism is arranged beside the connecting pipe 16. The temperature regulating mechanism is used to regulate the temperature of the physiological saline in the first shell 2. The shape of the third shell 15 is L-shaped, A second piston 17 is slidably connected to the inner side of the lateral end of the third housing 15 corresponding to the third through hole 18 , and a third spring is connected and fixed between the right side of the second piston 17 and the right inner wall of the third housing 15 19.

The computer is connected with the controller, the first laser range finder 14 and the second laser range finder 21, and the controller is connected with the temperature control mechanism and the alarm device. When it is necessary to detect the salt content of the physiological saline in the first casing 2 by the detection mechanism, the cooling liquid circulation delivery system 1 transports the physiological saline into the first casing 2 and completely sinks under the action of the first spring 7 into the physiological saline of the first shell 2, when the built-in catheter leaks, the salt content of the physiological saline will change. At this time, the first through hole 5 and the second through hole 6 do not communicate with each other, which can effectively prevent the device from The physiological saline is continuously input into the patient's body in batches; when the temperature of the physiological saline in the first shell 2 needs to be detected, the cavity at the bottom of the second shell 8 is filled with an expanding liquid, such as mercury, and the change in temperature of mercury The expansion and contraction of mercury is obvious, the expansion and contraction of mercury will drive the first piston 9 to slide vertically, and the first laser range finder 14 is used to detect the height of the first piston 9 and transmit the information to the computer.

When the frequency is too large, it proves that the pressure of the entire device is unstable, and the pressure is unstable, which will directly affect the treatment effect of the entire device on the patient. If the sliding range of the piston 17 is too large, it means that the water pressure of the physiological saline in the connecting pipe 16 is too large or too small, and the pressure is too small. It may be that there is a leak in the cooling liquid circulation delivery system 1 or the salt content of the normal saline is abnormal. Due to the blocking of the second through hole 6, when the frequency and amplitude of the lateral sliding of the second piston 17 are abnormal, the alarm device will be activated to give an alarm; the detection device has a simple structure and is easy to use, and can detect the salt content, Water pressure and water temperature are checked.
