[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0041] In some processes described in the specification, claims and the above-mentioned figures of this application, multiple operations appearing in a specific order are included, and these operations may not be executed or executed in parallel in the order in which they appear in this article. The serial numbers of the operations, such as 101, 102, etc., are only used to distinguish different operations, and the serial numbers themselves do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., do not represent the order of precedence, and do not limit "first" and "second" to different types. The embodiments described below are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0042] See also Figure 1 , Figure 2 and Figure 3 The medical heating system provided by one embodiment of the present application is shown. Figure 1 As shown, the medical heating system includes a main control device 1 and at least one heating device 2. For example, Figure 1 As shown in FIG. 1 , at least one heating device 2 may include but is not limited to: a blood transfusion and infusion warmer 23, an electric heating blanket 22, an air heating blanket ( Figure 1 The main control device 1 can provide working power to the heating device 2, and can also interact with the heating device 2 to control the heating device 2, receive or obtain the working information of the heating device 2 (such as the working temperature of the heating device, the working time of the heating device, etc.).

[0043] The main control device 1 is provided with a plurality of first electrical connectors 11. The structures of the plurality of first electrical connectors 11 are the same, and the heating device 2 can be randomly plugged into any first electrical connector 11; the heating objects targeted by the plurality of heating devices 2 are different. For example, the heating object targeted by the foot heating blanket is the foot. The heating objects targeted by the air heating blanket and the electric heating blanket can be the upper body, the lower body or the whole body. The heating object targeted by the upper limb heating blanket can be the arm. The heating object targeted by the blood transfusion and infusion warmer can be an infusion tube or bag, a blood transfusion tube or bag. In actual use, a certain number of heating devices and heating devices suitable for heating the corresponding parts can be selected and connected according to actual needs. Because the structures of the plurality of first electrical connectors 11 on the main control device 1 are the same, medical staff do not need to distinguish between the electrical connectors, and can plug in various types of heating devices in sequence, which is simple and efficient to connect.

[0044] See also Figure 2 and Figure 3 The main control device 1 shown may include an interactive device, a processor 14, a power adapter 15, a conversion circuit 16, and the like. The interactive device may include, but is not limited to, a display 13 or a touch screen, a voice interactive device, a control 17, and the like. The power adapter is used to electrically connect to the mains to convert alternating current into direct current (such as 24V direct current) adapted to the operation of the main control device 1. The conversion circuit is used to convert direct current into weak current with a lower voltage (such as 5V) to serve as the operating power supply for the processor. The control 17 may include: physical buttons, touch controls, knobs, and the like. The user may use the controls such as, but not limited to: turning the machine on and off, setting parameters of the main control device 1 (brightness adjustment, volume adjustment, etc.), and the like.

[0045] In view of the risk of hot-plugging the heating device in the prior art, the embodiments of the present application provide a corresponding solution, which can effectively solve or improve the risk of hot-plugging. In this way, medical staff can also hot-plug the heating device at any time according to the patient's body temperature to replace the heating device when the main control device is turned on.

[0046] The specific implementation structures of the main control device and the heating device are described below.

[0047] See also Figure 2 and Figure 4As shown, a main control device in a medical warming system provided in one embodiment of the present application. The main control device includes: an equipment body 10, an adapter board 12 and a plurality of first electrical connectors 11. Among them, the adapter board 12 is arranged on the equipment body 10, and is used to convert a first power supply into a second power supply; the voltage of the second power supply is less than the voltage of the first power supply. A plurality of first electrical connectors 11 are arranged on the equipment body 10 and are electrically connected to the adapter board 12, and are used to plug in a plurality of warming devices 2 to provide the first power supply and the second power supply to the warming devices; the structures of the plurality of first electrical connectors 11 are the same, and the warming device 2 can be randomly plugged in at any of the first electrical connectors 11.

[0048] The first power supply is used as the working power supply of the heating unit on the heating device, and the second power supply is used as the working power supply of the circuit board on the heating device. After the first electrical connector 11 is connected to the heating device 2, the second power supply is first provided to the heating device 2, and the first power supply is provided to the heating device 2 when the heating unit 203 on the heating device 2 needs to work.

[0049] In a specific embodiment, the first power supply may be a 24V DC power supply; the second power supply may be a 5V or 3.3V DC power supply. Of course, the above voltage values ​​are only illustrative examples. For different heating devices, the voltage of the first power supply and the voltage of the second power supply may be set according to the actual working requirements of the device.

[0050] In some embodiments, Figure 2 and Figure 3 As shown, the main control device may also include an interaction device and a processor 14. The interaction device is arranged on the device body 10. The processor 14 is arranged on the device body 10 and is electrically connected to the interaction device and the plurality of first electrical connectors 11, and is used to identify the target first electrical connector 11 in the plurality of first electrical connectors 11 that is plugged with the target heating device 2 specified by the user when the user triggers the start of heating through the interaction device, send a control instruction to the target heating device 2 through the target first electrical connector 11, and provide the first power supply to the target heating device 2 through the target first electrical connector 11.

[0051] Specifically, the first electrical connector 11 includes: a first power contact, a second power contact, and a first communication contact. The first power contact is connected to the first power supply, and after being electrically connected to the corresponding contact on the heating device 2, it provides a power supply of a first voltage to the heating device 2, so as to serve as a working power supply for the heating unit 203 on the heating device 2. The second power contact is connected to the second power supply, and after being electrically connected to the corresponding contact on the heating device 2, it provides a power supply of a second voltage to the heating device 2, so as to serve as a working power supply for the circuit board 202 on the heating device 2. The first communication contact is electrically connected to the processor, and is used to transmit control instructions from the processor 14 to control the heating device 2, and is also used to transmit information sent by the heating device 2 to the processor 14.

[0052] In a specific embodiment, the heating device 2 may send temperature information, heating duration, etc. to the main control device 1. After receiving the information sent by the heating device 2, the main control device 1 may control the heating device more accurately to make the heating device reach the target temperature.

[0053] Furthermore, the processor 14 in this embodiment may also be used for:

[0054] The identification of the heating device 2 connected to the first electrical connector 11 is obtained through the communication contact of the first electrical connector 11; based on the identification, the heating device 2 connected to the first electrical connector 11 is identified for targeted control.

[0055] For example, during an operation, medical staff Figure 4The four first electrical connectors 11 shown in the figure are respectively connected to: a blood transfusion and infusion warmer, an upper limb warming device and a foot heating blanket from left to right, and there is one electrical connector 11 left without a warming device. For the convenience of description, the four first electrical connectors 11 are respectively referred to as: a first electrical connector A, a first electrical connector B, a first electrical connector C, and a first electrical connector D from left to right. At this time, the processor 14 of the main control device 1 can obtain the identification of the blood transfusion and infusion warmer plugged into the first electrical connector A through the communication contacts of the first electrical connector A, obtain the identification of the upper limb warming device plugged into the first electrical connector B through the communication contacts of the first electrical connector B, and obtain the identification of the foot heating blanket plugged into the first electrical connector C through the communication contacts of the first electrical connector C. Assume that the user triggers the start of the blood transfusion and infusion warmer through the interactive device, and the heating temperature is 30°C. Based on the above-obtained identification, the processor 14 can recognize that the first electrical connector A is plugged into the blood transfusion and infusion warmer. Thus, in response to the user's trigger, the processor 14 controls the first electrical contact of the first electrical connector A to provide the first power supply to the blood transfusion and infusion warmer, and sends a control instruction to the circuit board of the blood transfusion and infusion warmer through the first communication contact of the first electrical connector A, so that the circuit board of the blood transfusion and infusion warmer controls the heating unit to work based on the control instruction to reach the target heating temperature of 30°C.

[0056] Furthermore, the main control device in this embodiment can also be designed as follows Figure 5 The structure of Figure 5 As shown, the device body 10 of the main control device 1 is provided with a plurality of installation openings 101. The installation openings 101 are provided with a plurality of electrical connection terminals (not shown in the figure). Figure 6 As shown, the first electrical connector 11 is detachably disposed in the mounting port 101 and is electrically connected to the plurality of electrical connection devices in the mounting port 101 so as to be electrically connected to the processor 14 and the adapter board 12 through the plurality of electrical connection terminals.

[0057] With this design, the application range of the main control device is wider, and more types of heating devices can be adapted by changing the structure of the first electrical connector 11, and the user does not need to consider the adaptation problem between the heating device and the main control device.

[0058] See also Figure 7 Another embodiment of the present application provides a heating device. The heating device includes: a device body, a heating unit, a circuit board and a second electrical connector. For different types of heating devices, the shape of the device body is different. Figure 1 As shown, the device body of the foot heating blanket 21 is shaped as follows Figure 1 The shape of the device body of the blood transfusion and infusion warming device 23 is as shown in Figure 1Therefore, the embodiment of the present application does not specifically limit the form (or structure) of the device body. The heating unit 203 is arranged on the device body for heating and heating. The circuit board 202 is arranged on the device body, and the circuit board 202 is provided with a storage unit and a control unit; the control unit is used to read the identification of the heating device 2 stored in the storage unit, and is also used to control the operation of the heating unit. The second electrical connector 201 is arranged on the device body, and is electrically connected to the circuit board 202 and the heating unit 203, and is used to be electrically connected to the first electrical connector 11 on the main control device 1.

[0059] After the second electrical connector 201 is electrically connected to the first electrical connector 11, the second electrical connector 201 is first connected to the second power supply provided by the first electrical connector 11 as the working power supply of the circuit board 202; when the heating unit 203 needs to work, the first power supply provided by the first electrical connector 11 is connected to the first power supply provided by the first electrical connector 11 as the working power supply of the heating unit 203. The voltage of the second power supply is lower than the voltage of the first power supply.

[0060] For example, in the example provided above, the voltage of the second power supply may be 5V; and the voltage of the first power supply may be 24V.

[0061] Specifically, the second electrical connector 201 may include: a third power contact, a fourth power contact and a second communication contact. The third power contact is electrically connected to the heating unit 203, and is used to be electrically connected to the first power contact of the first electrical connector 11 to access the first power supply. The fourth power contact is electrically connected to the circuit board 202, and is used to be electrically connected to the second power contact of the first electrical connector 11 to access the second power supply. The second communication contact is electrically connected to the circuit board 202, and is used to be electrically connected to the first communication contact of the first electrical connector 11, and is used to transmit control instructions of the master device to the circuit board 202, and is also used to send information to the master device 1.

[0062] Furthermore, the second electrical connector 201 may also be provided with a short-circuit pin, and the control unit determines the connection state between the second electrical connector 201 and the first electrical connector 11 by reading the high and low levels of the short-circuit pin. Alternatively, the control unit determines the connection state between the second electrical connector 201 and the first electrical connector 11 according to the data transmission state with the main control device 1. For example, the control unit sends a first signal to the main control device 1 through the second electrical connector 201. If the control unit does not receive a first response fed back by the main control device 1 through the first electrical connector 11 within a preset time, it is determined that the second electrical connector 201 is disconnected from the first electrical connector 11 and is in a disconnected state. If the control unit receives a first response fed back by the main control device 1 through the first electrical connector 11 within a preset time, it is determined that the second electrical connector 201 and the first electrical connector 11 are in a connected state.

[0063] Furthermore, the heating device provided in this embodiment may further include an alarm device. If the second electrical connector is disconnected from the first electrical connector, the control unit controls the alarm device to output a disconnection alarm message. The alarm device may be a buzzer, an alarm light, and the like.

[0064] See also Figure 7 As shown, the heating device provided in this embodiment may further include a sensor. The sensor 204 is electrically connected to the circuit board 202 and is used to detect the temperature of the device body. The control unit on the circuit board 202 is used to obtain the temperature detected by the sensor 204 and send the temperature to the main control device 1 through the second electrical connector 201.

[0065] The sensor 204 can be a temperature sensor. In a specific implementation, the sensor 204 can be connected to the circuit board 202 through a wiring terminal, and the sensor transmits the real-time collected temperature to the circuit board 202 in the form of a resistance value. Since the communication is transmitted in a single-channel manner, the control unit on the circuit board 202 controls the analog switch to read the output value of the sensor 204 in a time-division multiplexing manner, and then transmits the signal to the control unit after processing through a filter circuit. The ADC of the control unit converts the input analog signal into a digital signal and then passes it through the communication contacts of the second electrical connector and the first electrical connector (i.e., the RS-485 circuit). The RS-485 circuit performs differential processing on the received signal and sends the digital signal to the processor of the main control device, thereby completing the process of temperature information feedback by the heating device.

[0066] After the heating control part of the heating device sends the heating target temperature to the control unit on the circuit board 202 of the heating device by the main control device, the control unit outputs PWM control heating by controlling the MOS tube according to the program, so as to achieve the effect of the set temperature.

[0067] Since the heating device provided in this embodiment is a medical device, both the heating tube and the heating blanket are equipped with fuses as secondary protection when a single fault occurs in the medical device. For example, when the program freezes and the heating is out of control, the fuse will automatically cut off the power when it detects that the temperature is too high, thus ensuring the safety of the system equipment.

[0068] Furthermore, the heating device in this embodiment may also have an expansion connector 205. Figure 8 As shown, other heating devices can be cascaded through the extension connector 205. For example, the heating device in this embodiment is an upper limb heating blanket, and the foot heating blanket can be cascaded to the upper limb heating blanket through the extension connector on the upper limb heating blanket, so that a first electrical connector on the main control device does not need to be occupied.

[0069] For ease of description, the heating device provided in this embodiment with the expansion connector 205 is referred to as a first heating device, and the heating device connected to the second electrical connector 201 of the first heating device through the expansion connector 205 is referred to as a second heating device. The structure of the second heating device may have the following features: Figure 7 The structure shown. The second connector of the second heating device is electrically connected to the extension connector of the first heating device. The first heating device can provide the first power supply and the second power supply for the second heating device, and can also serve as a communication transfer device between the second heating device and the main control device. The second heating device can send its own identification to the main control device through the extension connector and the second electrical connector of the first heating device. In addition to carrying the identification of the second heating device, the message in which the second heating device sends its own identification also carries the identification of the first heating device, so that the main control device can recognize that the second heating device is a device cascaded through the first heating device. When the user triggers the start of the second heating device through the interactive device, the main control device sends the control instruction for the second heating device to the first heating device based on the above-mentioned recognition result. The control instruction not only carries the instruction to control the operation of the second heating device, but also includes the instruction to instruct the first heating device to forward to the second heating device. After receiving the control instruction, the first heating device sends the control instruction to the second heating device through the extension connector. When the second heating device sends information (such as temperature information or heating time, etc.) to the main control device, similarly, the information is sent to the first heating device, which is forwarded to the main control device by the first heating device.

[0070] In the solution provided in this embodiment, the main control device provides two power supplies for the heating device. The second power supply with a lower voltage is first provided to the heating device, and the first power supply with a higher voltage is provided to the heating device when the heating device is required to work. In this way, when the heating device is hot-plugged, the circuit with a higher voltage is in a power-free state, and hot plugging is relatively safer. Because the lower second power supply is provided first, the power supply voltage and current are relatively small, which can generate relatively small sparks or ripples, making it easier to eliminate interference, and ensuring that the subsequent circuit is more stable. In addition, an adapter board is provided in the main control device, so that there is no need to set a voltage conversion circuit on the heating device, which greatly reduces the circuit board space and cost of the heating device, and makes production more convenient and reasonable, greatly improving production efficiency.
