Technical Field

[0001] The utility model relates to the technical field of infusion auxiliary equipment, in particular to an infusion heating device. Background Art

[0002] Under battlefield conditions in cold regions, blood loss and hypothermia are important factors leading to the death of the wounded. For the wounded who have lost a lot of blood, rapid intravenous blood transfusion and infusion are necessary to quickly replenish the blood volume. However, if the temperature of the liquid medicine is too low, it will cause hypothermia in the wounded, often causing the patient's limbs to become cold, or even numb and painful. In severe cases, it will increase the risk of infection at the trauma site, increase cardiovascular system complications, and cause vasospasm, phlebitis, or life-threatening vascular sclerosis, as well as coagulation disorders. Therefore, there is an urgent need for an efficient, fast, accurate, and stable blood transfusion and infusion heating and rewarming device that can be used for aeromedical evacuation to improve the blood transfusion medical support capabilities and levels during combat trauma treatment.

[0023] In the embodiment, a PLC controller is fixed to the inner bottom surface of the shell 1, and a battery is also fixed to the inner bottom surface of the shell 1. The battery is electrically connected to the PLC controller through a DC voltage regulator module, and the touch screen 3, the temperature sensor 202 and the heating wire 201 are all electrically connected to the PLC controller. The temperature of the medicine inside the infusion tube is detected by the two temperature sensors 202, and the heating wire 201 cooperates with the built-in temperature control system controlled by the PLC to achieve precise temperature control of the heating tube, and the touch screen 3 is used to control the device to perform operations such as rapid heating, precise temperature control, low temperature alarm, and over-temperature power-off protection. It is suitable for use during aviation medical evacuation.

[0024] In the embodiment, a through groove 205 is provided on the outer wall of the heating sleeve 2, and the through groove 205 is connected with the interior of the heating chamber 206. The through groove 205 includes an expansion section and a main section. The expansion section is 1 cm long at the outlet of the heating chamber 206, and the main section is 50-100 cm long at the entrance of the heating chamber 206. By setting the through groove 205, the infusion tube is placed into the heating chamber from the expansion section of the through groove 205, and then the infusion tube is pressed by one hand to make it close to the wall of the heating chamber, and the other hand takes the expansion section of the through groove 205 as the starting point and strokes the infusion tube along the through groove, so as to press the infusion tube into the heating chamber and realize the clamping of the infusion tube.

The other hand uses the expanded section of the through groove 205 as the starting point and strokes the infusion tube along the through groove, so as to press the infusion tube into the heating chamber and realize the card connection of the infusion tube. Then, the touch display screen 3 is turned on, and the preset temperature of the low temperature alarm and the over-temperature power-off protection is set, and then the rapid heating is set to the preset temperature. At this time, the PLC controller sends an electrical signal to control the heating wire 201 to heat the infusion tube, and the temperature sensor 202 transmits the detected infusion tube temperature to the PLC controller through an electrical signal, and the heating of the heating wire 201 is controlled by the built-in temperature control algorithm of the PLC controller, thereby realizing the heating of the infusion tube.
