[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] like Figures 1 to 5 As shown, Example 1 of the utility model is a flexible heating plate for replacement fluid adapted for the Fessen CRRT treatment machine, comprising a flexible heating plate 1 fitted on a scale 61 of the Fessen CRRT treatment machine body 6, the flexible heating plate 1 comprising an upper plate 11 and a lower plate 12 stacked up and down, a heating guide wire 2 for heating the finished replacement fluid 7 on the scale 61 is laid in the upper plate 11, an air bag 121 is embedded in the lower plate 12, and the upper and lower sides of the inner wall of the air bag 121 are respectively provided with the male and female heads of the contact switch 3; the contact switch 3 and the heating guide wire 2 are electrically connected to the power supply in the Fessen CRRT treatment machine body 6; a plurality of water bags 8 are provided on the front of the Fessen CRRT treatment machine body 6.

[0021] After the finished replacement fluid 7 is placed on the flexible heating plate 1, the finished replacement fluid 7 squeezes the airbag 121, so that the male and female ends of the contact switch 3 are in contact, the electric heating guide wire 2 is connected to the power supply, and the electric heating guide wire 2 heats the finished replacement fluid 7 on the upper part of the upper plate 11; when the replacement fluid in the finished replacement fluid 7 is exhausted or the finished replacement fluid 7 is removed, the airbag 121 returns to its original state, so that the male and female ends of the contact switch 3 are disconnected, the electric heating guide wire 2 is disconnected from the power supply, and the heating of the finished replacement fluid 7 is stopped; by setting the flexible heating plate 1, the replacement fluid placed on the scale 61 is heated. The finished replacement fluid 7 is heated. The finished replacement fluid 7 is used as the source of the extracorporeal circulation and is heated. At the same time, the water bag 8 originally provided in the Fessen CRRT treatment machine body 6 is used for heating. The heating effect is good. The replacement fluid close to the patient's body temperature is used for CRRT treatment, and the patient is less likely to induce complications such as arrhythmia and thromboembolism. In addition, the air bag 121 and the contact switch 3 enable the electric heating guide wire 2 to automatically heat when there is finished replacement fluid 7 on the flexible heating plate 1, and automatically stop heating when there is no finished replacement fluid 7. The operator does not need to perform additional operations and it is energy-saving.

[0022] Example 2 of the present invention is a flexible heating plate for replacement fluid adapted for the Fessen CRRT treatment machine. Based on Example 1, it further includes an electronic thermometer 4 and a temperature control switch 5. The temperature control switch 5 is provided on the connection circuit between the heating guide wire 2 and the power supply, and the electronic thermometer 4 is embedded on the upper plate 11; the temperature control switch 5 is a knob-type switch. The electronic thermometer 4 monitors the temperature of the upper plate 11 in real time, making it convenient for medical personnel to know the heating and insulation conditions of the replacement fluid. At the same time, it also makes it convenient for medical personnel to use the temperature control switch 5 to adjust the heating power of the heating guide wire 2, thereby adjusting the heating and insulation temperature of the replacement fluid; the knob-type switch is convenient and fast in temperature adjustment. In specific implementation, the temperature adjustment range is 37-50°C, which can be reasonably set in combination with the patient's condition and ambient temperature.

[0023] Example 3 of the present invention is a flexible heating plate for replacement fluid adapted for a Fessen CRRT treatment machine. Based on Example 1, both the upper plate 11 and the lower plate 12 are made of silicone. The silicone is soft and elastic, conforming more closely to the surface of the finished replacement fluid 7 and the scale 61, and preventing slipping.

[0024] Embodiment 4 of the present invention is a flexible heating plate for replacement fluid adapted for a Fessen CRRT treatment machine. Based on embodiment 1, anti-slip teeth 122 are provided at the bottom of the lower plate 12 to further enhance the anti-slip performance of the flexible heating plate 1 and prevent it from sliding off the scale 61.

[0025] Example 5 of the present invention is a flexible heating plate for replacement fluid adapted for a Fessen CRRT treatment machine. Based on any of Examples 1 to 4, the airbag 121 is a TPU double-layer airbag. TPU double-layer airbags have the advantages of being lightweight, strong, and resistant to wear and corrosion, making them suitable for use in the flexible heating plate 1.
