[0033] A temperature sensor 5 and an electric heating rod 6 are mounted in the water tank 4, the temperature sensor 5 is a PT100 type thermal resistance sensor, which is used to monitor the water temperature in the water tank 4 in real time, the electric heating rod 6 has a power of 500W and is made of a stainless steel shell, which is corrosion-resistant and has high heating efficiency. The temperature sensor 5 and the electric heating rod 6 are connected with a PLC controller mounted in the shell 1, the PLC controller is a Siemens S7-200 type, which can automatically control the start and stop of the electric heating rod 6 according to the feedback signal of the temperature sensor 5, and stabilize the water temperature in the water tank 4 at a set value (for example, 37℃).

[0034] A control switch and a power supply interface are arranged on the outer wall of the shell 1, the control switch is used to control the power switch and temperature setting of the device, one end of the control switch is connected with the PLC controller, and the other end is connected with the power supply interface. The power supply interface is a 220V AC power supply interface, which meets the safety standard of medical equipment.

[0035] A drain pipe 7 is further mounted on the side wall of the water tank 4, the drain pipe 7 has a diameter of 20mm and is provided with a manual valve, which is convenient for regularly replacing the water in the water tank 4 or cleaning the water tank 4. A threaded interface is arranged at the end of the drain pipe 7, which can be connected with an external drainage system.

[0036] In order to enhance the stability of the device, suction cups are arranged at the four corners of the bottom of the shell 1. The suction cups are made of rubber material and can be firmly adsorbed on the smooth workbench to prevent the device from sliding during use.

[0037] Working principle:

[0038] In use, first, the power supply is connected through the power supply interface, the control switch is turned on, and the target temperature (for example, 37℃) in the water tank 4 is set. The PLC controller starts the electric heating rod 6 to heat the water in the water tank 4, the temperature sensor 5 monitors the water temperature in real time and feeds back to the PLC controller until the water temperature reaches the set value.

[0039] Before operation, the phlebotomist takes the alcohol-soaked cotton wool 9 from the groove of the panel 2, disinfects the hands, and ensures the hygiene and safety of the operation. Then, the blood collection tube is inserted into the hole of the upper plate 31, and is placed in the corresponding area according to the type of the blood collection tube: the purple EDTA anticoagulant blood collection tube is placed in the left purple area, and the red coagulant blood collection tube is placed in the right red area. The blood collection tube placement structure 3 is placed in the sink 4 as a whole, the bottom of the blood collection tube is in contact with water through the hollow part of the lower plate 33, and the temperature is kept constant.
