[0036] The main body 110 is provided with a heating chamber and an opening connected to the heating chamber, and the heating chamber is used to accommodate one or more blood bags; a first connecting portion 140 and a second connecting portion 150 are respectively provided on opposite sides of the main body 110, and the first connecting portion 140 is used to be detachably connected to the second connecting portion 150 of the external main body 110; the movable cover 120 is movably connected to the main body 110 to close or open the opening; the heating component 130 is connected to the main body 110, and the heating component 130 is used to heat the blood bag located in the heating chamber.

[0037] Please refer to Figure 1-Figure 4 The working principle of the blood rewarming device 200 is:

[0038] First, the blood rewarming device 200 includes at least one rewarming unit 100, each of which includes a main body 110, a movable cover 120 and a heating assembly 130; the main body 110 is provided with a heating chamber and an opening communicating with the heating chamber, and the heating chamber is used to accommodate one or more blood bags; in this embodiment, each heating chamber is used to accommodate one blood bag as an example for explanation, and in addition, in this embodiment, since the blood bags have different volumes, when configuring the main body 110, main bodies 110 of multiple volumes can also be configured according to the use requirements, so that each main body 110 can accommodate a blood bag of one volume;

[0039] Therefore, by making each heating chamber corresponding to a blood bag, the structural volume of a single rewarming unit 100 can be reduced, so that it is convenient for medical staff to use and easy to carry and transfer;

[0040] When the blood rewarming device 200 is used to rewarm a blood bag, the movable cover 120 can be operated to place the blood bag to be rewarmed into the heating chamber, and then the movable cover 120 can be closed to reduce the heat exchange between the heating chamber and the outside, so as to improve the heating efficiency of the heating component 130 on the blood bag when the heating component 130 is working;

[0041] Moreover, during use, different blood bag rewarming requirements exist in different usage scenarios, and on the basis that each heating chamber accommodates a blood bag, since the first connecting portion 140 and the second connecting portion 150 are respectively provided on opposite sides of the main body 110, the first connecting portion 140 is used to be detachably connected to the second connecting portion 150 of the external main body 110; therefore, a plurality of rewarming units 100 can be configured, and the plurality of rewarming units 100 can be connected to two rewarming units 100 through the cooperation of the first connecting portion 140 and the second connecting portion 150 on the main body 110, thereby enabling the plurality of rewarming units 100 to be connected together, so as to facilitate their carrying and use;

[0042] In summary, the blood rewarming device 200 has a simple structure and is easy to move and carry. It can provide medical staff with fast and accurate blood bag rewarming services in different scenarios while ensuring the quality of blood rewarming, thereby ensuring blood quality and blood transfusion safety; it can also expand the number of rewarming units 100 according to the usage requirements of different scenarios to adjust the capacity of the blood bags that can be rewarmed, thereby improving its flexibility of use.

[0043] Please refer to Figure 1-Figure 4 In this embodiment, when configuring the heating component 130, there are multiple heating methods. In this embodiment, in order to reduce the structural volume of each rewarming unit 100 and improve its heating efficiency, the heating component 130 may include a heat conducting plate 131 and a heating wire group 132. The heat conducting plate 131 is distributed on the inner side of the heating chamber, and the heating wire group 132 is evenly distributed between the heat conducting plate 131 and the inner wall of the heating chamber. Through such a configuration, the heat generated by the heating wire group 132 can be transferred from the surroundings of the heating chamber to the blood bag in the heating chamber through the heat conducting plate 131, so that the blood bag can be evenly heated, thereby improving the rewarming quality of the blood bag. In addition, in order to reduce the heat dissipated from the heating component 130 to the outside, a heat preservation layer 112 is configured on the periphery of the main body 110.

[0044] Furthermore, in this embodiment, in order to facilitate the control of the working state of the heating component 130 and facilitate the staff to grasp the working state of the heating component 130, the heating component 130 also includes a heating control board and a display screen 133; the heating control board is connected to the main body 110, the display screen 133 is connected to the outside of the main body 110, and the display screen 133 and the heating wire group 132 are both electrically connected to the heating control board. Through the setting of the heating control board, the working state of the heating wire group 132 can be controlled, so that the staff can control the heating control board through the control buttons configured on the main body 110 based on the relevant data obtained by the display screen 133.

[0045] It should be noted that the heating control board can adopt structures such as a single-chip microcomputer or a controller in the prior art, and the display screen 133 can be a liquid crystal screen in the prior art, or a touch screen, and an indicator light and an alarm 134 electrically connected to the heating control board can also be provided. The alarm 134 can be a buzzer, and its specific structure and principle are not repeated here; therefore, during use, after placing the blood bag in the rewarming unit 100, and then locking the movable cover 120 to start the rewarming, the heating control board can be controlled by the control button on the main body 110, and the rewarming parameters and time are adjusted in advance. The temperature is displayed in real time through the display screen 133. After the rewarming is completed, the green light is on, an alarm prompts, and the temperature enters a constant temperature state.

[0046] In the above steps, in order to detect the temperature in the heating chamber while the heating wire group 132 is working, so that the staff can control the rewarming unit 100, the blood rewarming device 200 also includes a plurality of temperature measuring thermocouples electrically connected to the heating control board, and the plurality of temperature measuring thermocouples are arranged in the heating chamber and arranged at intervals. It can be understood that by arranging the plurality of temperature measuring thermocouples at intervals, data at different positions in the heating chamber can be collected, so as to know the temperature state of each location in the heating chamber, so as to heat the blood bag uniformly, thereby avoiding local overheating. In addition, in order to improve the uniformity of the heating of the blood bag, the blood rewarming unit 100 also includes four vibrators 160, the four vibrators 160 are all electrically connected to the heating control board, and the four vibrators 160 are distributed around the heating chamber and located at the bottom of the heating chamber.

[0047] For further information, please refer to Figure 1-Figure 4During operation, the heating component 130 can use a built-in power supply or an external power supply. In the present embodiment, in order to simplify the structural volume of the rewarming unit 100, a power interface 111 is configured on the main body 110. The power interface 111 is electrically connected to the heating control board, and can be electrically connected to an external power supply device, and the external power supply device can be a portable power bank. In other embodiments of the utility model, when a built-in power supply is used, in order to simplify its structural volume, an installation cavity can be configured at the bottom of the main body 110. The heating component 130 also includes a power supply. The power supply and the heating control board are both accommodated in the installation cavity, and the power supply is electrically connected to the heating control board.

[0048] For further information, please refer to Figure 1-Figure 7 In this embodiment, when the blood rewarming device 200 includes a plurality of rewarming units 100, the plurality of rewarming units 100 are docked by means of the cooperation of the first connection part 140 and the second connection part 150. Specifically, the first connection part 140 includes a plurality of slots 141 provided in the main body 110, and the second connection part 150 includes a plurality of latches 151 connected to the main body 110, and each latch 151 is used to engage with a slot 141. Thus, the plurality of rewarming units 100 can be docked by means of the one-to-one engagement of the plurality of latches 151 and the plurality of slots 141.

[0049] On this basis, in order to simplify the structural volume of the main body 110 and to avoid the exposure of the latch 151 to affect the structural appearance and its normal use when the rewarming unit 100 is used alone, the main body 110 is provided with a plurality of mounting holes 113 and a plurality of toggle holes 114, each mounting hole 113 is correspondingly connected to a toggle hole 114, and each mounting hole 113 is distributed on two adjacent sides of the main body 110 with the corresponding toggle hole 114; each latch 151 includes a plug-in portion 152 and a toggle portion 153, and the toggle portion 153 is connected to the plug-in portion 152; the plug-in portion 152 is slidably matched with the corresponding mounting hole 113, and the plug-in portion 152 has a position for being received in the mounting hole 113 and a position for protruding from the mounting hole 113 and engaging with the slot 141; the toggle portion 153 is matched with the corresponding toggle hole 114. Therefore, in this way, by operating the toggle portion 153 located in the toggle hole 114, the plug-in portion 152 can slide out of the mounting hole 113 or slide into the mounting hole 113, and then the latch 151 can be stored, so as to improve its overall aesthetics when the rewarming unit 100 is used alone, and avoid the exposed latch 151 affecting its use.

[0050] Further, from the above content, please refer to Figure 1-Figure 7In this embodiment, the blood rewarming device 200 adjusts the working condition of the heating component 130 by controlling the heating control panel. In this process, when the blood rewarming device 200 includes a plurality of docked rewarming units 100, one of the rewarming units 100 is powered by an external power supply device, and all the rewarming units 100 are controlled by a control operation panel of the rewarming unit 100. Therefore, a method of connecting the plurality of rewarming units 100 in communication can be adopted, so that the blood rewarming device 200 can be controlled by controlling one of the rewarming units 100. The blood rewarming device 200 is used to control all the rewarming units 100 in the device 200, so the blood rewarming device 200 also includes a first communication connector 171 and a second communication connector 172; the first communication connector 171 and the second communication connector 172 are both electrically connected to the heating control board; one of the plug-in parts 152 is hollow, and the first communication connector 171 is accommodated in the plug-in part 152, and the second communication connector 172 is accommodated in one of the slots 141; the first communication connector 171 is used to electrically connect with the second communication connector 172 in the slot 141 when the plug-in part 152 is matched with the external slot 141. It should be noted that such a setting method can make the first communication connector 171 located at the end of the plug-in part 152, or it can be located inside the plug-in part 152, so that multiple rewarming units 100 can be connected in communication on the basis of one-to-one matching of multiple plug-in parts 152 and multiple slots 141.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
