[0028] The technical solutions 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. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. The "including" mentioned in the entire specification and claims is an open term, so it should be interpreted as "including but not limited to" and "approximately" means that within an acceptable error range, those skilled in the art can solve the technical problems within a certain error range and basically achieve the technical effects.

[0029] In addition, in the embodiments of the present application, a plurality refers to two or more. Without being contradictory, those skilled in the art may combine and combine the different embodiments or examples and the features of the different embodiments or examples described in this specification.

[0030] For some seriously ill patients, abnormal body temperature is very likely to occur during the treatment and recovery process. If it is not controlled in time, it may cause metabolic dysfunction and even endanger life. For such patients, hospitals often use heating equipment to keep the patients warm to prevent them from having low body temperature.

[0031] In order to meet the needs of different patients, there are many types of heating equipment, such as blood transfusion and infusion warmers, electric heating blankets, air heating blankets, foot heating blankets and arm heating blankets. General heating blankets have problems such as uneven heating and poor user experience. In order to solve this type of problem, an inflatable heating blanket is widely used. This inflatable heating blanket has better wrapping, more uniform overall temperature, and better insulation effect for patients. However, this inflatable heating blanket has a complex internal structure, is often large in size, and is inconvenient to use.

[0032] In order to solve the above technical problems, see Figure 1 and Figure 2 In one embodiment of the present application, an inflatable medical warming system is provided, which includes a heating management device 1 and an inflatable warming device 2. The heating management device 1 has a plurality of interfaces 11 of the same specification, and the interfaces 11 are arranged on the device body of the heating management device 1. The inflatable warming device 2 includes a first control unit 22, a heating unit 23 and an inflating unit 24, and the heating unit 23 and the inflating unit 24 are electrically connected to the first control unit 22 respectively. The first control unit 22 can control the heating unit 23 to heat and the inflating unit 24 to inflate or deflate respectively.

[0033] Among them, the inflatable heating device 2 has at least one connector 21, and the connector 21 on the inflatable heating device 2 can be connected to any interface 11 on the heating management device 1, so as to realize the electrical connection between the heating management device 1 and the inflatable heating device 2. When the connector 21 is connected to the interface 11, the heating management device 1 is connected to the first control unit 22 in communication, and the heating management device 1 provides the first control unit 22 with a power source adapted for power. After obtaining the adapted power source, the first control unit 22 can distribute the power source to the heating unit 23 and the inflatable unit 24. In a specific embodiment, a preset power distribution algorithm is stored in the first control unit 22, and the first control unit 22 can distribute the above power source to the heating unit 23 and the inflatable unit 24 respectively according to the power distribution algorithm. Of course, the first control unit 22 can also obtain the information fed back by the heating unit 23 and the inflatable unit 24, and then distribute the power source to the heating unit 23 and the inflatable unit 24 according to the needs of the heating unit 23 and the inflatable unit 24, so as to realize the function of dynamically adjusting the inflatable heating device 2.

[0034] For different models of inflatable heating devices 2, the heating power is also different. When multiple different models of inflatable heating devices 2 are connected to the heating management device 1 at the same time, the heating management device 1 can respectively identify the models of different inflatable heating devices 2, and then output the power compatible with the heating management device 1 through the electrically connected interface 11.

[0035] In addition, the connector 21 on the heating management device 1 can also be used to connect to other types of heating devices, such as a blood transfusion and infusion warmer, an electric heating blanket, a foot heating blanket, etc.

[0036] As mentioned above, the heating management device 1 is electrically connected to the inflatable heating device 2 through an interface 11. After obtaining the adapted power provided by the heating management device 1, the first control unit 22 of the inflatable heating device 2 can distribute the adapted power to the heating unit 23 and the inflatable unit 24. In another embodiment provided in the present application, the inflatable heating device 2 can also be connected to multiple interfaces 11 on the heating management device 1 through multiple connectors 21.

[0037] Specifically, since the power that can be output by an interface 11 on the heating management device 1 is limited, when the power of the inflatable heating device 2 is relatively large, a plurality of connectors 21 can be configured on an inflatable heating device 2, and the plurality of connectors 21 are connected in parallel to meet the power supply needs of the high-power inflatable heating device 2. In addition, a connector 21 can also be configured for different components. For example, the heating unit 23 is electrically connected to a connector 21, and the inflatable unit 24 is electrically connected to a connector 21. In this way, when the two connectors 21 are respectively connected to the heating management device 1, the heating management device 1 can supply power to them respectively and control the two unit components separately.

[0038] See also Figure 1 and Figure 2 In one embodiment provided in the present application, the heating management device 1 includes a second control unit 12 and a power supply device 13. The second control unit 12 is used to control the power output of the power supply device 13; the power supply device 13 is electrically connected to a plurality of connectors 21, respectively, and can provide power-adaptive power to the heating unit 23 and the inflation unit 24 of one or more inflatable heating devices 2, respectively. The power supply device 13 can control the power supply and power failure of the interface 11, the power supplied by the interface 11, the stability of the power supply (voltage stabilization), etc. The power supply device 13 can realize the above functions mainly based on the control signal of the second control unit 12. The second control unit 12 can receive the user's operation signal, and then output the control signal according to the operation signal to realize the control of the power supply device 13.

[0039] See also Figure 1 and Figure 2In one embodiment provided in the present application, the inflatable unit 24 is connected in series with the heating unit 23, and the heating unit 23 can heat the airflow delivered by the inflatable unit 24, and the heated airflow is output to the inflatable warming device 2. Specifically, the inflatable unit 24 delivers the outside air to the inflatable warming device 2, the heating unit 23 can heat this part of the air, and then the inflatable warming device 2 can store this part of the heated air, thereby achieving heating of the patient's body.

[0040] In the technical solution provided in the present application, the inflatable unit 24 and the heating unit 23 have a variety of different working modes. One of them is that when the inflatable unit 24 starts to transport air to the inside of the inflatable heating device 2, the heating unit 23 starts at the same time, and the air is heated during the process of being transported inward. Another is that the inflatable unit 24 first starts for a first preset time, for example, 3 seconds, 5 seconds, etc. Then the heating unit 23 starts again to heat the air transported inward. This method is safer. Another is that the inflatable unit 24 directly and continuously transports air to the inside of the inflatable heating device 2. When the inside of the inflatable heating device 2 is filled, the heating unit 23 heats the air inside the inflatable heating device 2. During this process, the inflatable unit 24 can turn off the external circulation mode and start the internal circulation mode until the air inside the inflatable heating device 2 is heated to a suitable temperature.

[0041] As mentioned above, the inflatable warming device 2 mainly stores heated air and then uses the heated air to heat or keep the patient's body warm. Figure 1 and Figure 2 In one embodiment provided in the present application, the inflatable heating device 2 is an inflatable heating blanket. The inflatable heating device 2 includes at least one airbag 25. The inflatable unit 24 can deliver the airflow to the airbag 25, or discharge the airflow in the airbag 25. Specifically, the inflatable unit 24 can deliver the heated airflow to the airbag 25, or directly deliver the outside air to the airbag 25. When the air in the airbag 25 needs to be discharged, the inflatable unit 24 opens the inflation path, and the pressurized air in the airbag 25 can be discharged to the outside.

[0042] The inflatable heating blanket has two main processes during use, one is the inflation process, and the other is the continuous heat preservation process. In an embodiment provided in the present application, the inflatable heating device 2 has an inflation state and a cyclic heating state; in the inflation state, the inflation unit 24 delivers external air to the airbag 25; and the heating unit 23 can heat the air during the inflation process, or heat the air in the airbag 25 after the inflation is completed.

[0043] When the air pressure in the airbag 25 meets the requirements, but the temperature of the air in the airbag 25 is lower than the preset value, the inflatable heating device 2 needs to increase the temperature of the air in the airbag 25 in the circulating heating state, so as to achieve continuous heat preservation. In the circulating heating state, the inflatable unit 24 circulates and heats the air in the airbag 25. In the circulating heating state, the air in the airbag 25 can be circulated, and the heating unit 23 heats the air again during the air flow. By circulatory heating of the air in the airbag 25, not only can the temperature uniformity of the air in the airbag 25 be better, but also more power saving.

[0044] Further, through the above description, it can be understood that the inflatable heating device 2 has an internal circulation mode and an external circulation mode. In order to facilitate the inflatable heating device 2 to switch between these two modes at will, in an embodiment provided in the present application, the inflatable unit 24 also includes a valve body device 26, and the valve body device 26 has two air inlets and one exhaust port. The first air inlet and the exhaust port are located in the airbag 25, and the second air inlet is located outside the airbag 25; in the inflated state, the exhaust port is connected to the second air inlet; the inflatable unit 24 sucks the external air through the second air inlet, and then delivers the air to the airbag 25 through the exhaust port. In the circulating heating state, the exhaust port is connected to the first air inlet; the inflatable unit 24 sucks the air in the airbag 25 through the first air inlet, and then discharges it into the airbag 25 through the exhaust port, thereby realizing the circulation of air.

[0045] In a specific embodiment, the valve body device 26 is a normally closed solenoid valve. When the solenoid valve is not energized, the second air inlet and the exhaust port are closed, and the first air inlet and the exhaust port are connected; when the solenoid valve is energized, the second air inlet and the exhaust port are connected, and the first air inlet and the exhaust port are closed.

[0046] See also Figure 1 and Figure 2 The inflatable heating device 2 may include one airbag 25 or multiple airbags 25. Taking the inflatable heating device 2 with multiple airbags 25 as an example, the multiple airbags 25 are independent of each other, and the inflatable unit 24 can transport air to different airbags 25 respectively. Specifically, the inflatable heating device 2 also includes an air separator 241, and the air separator 241 has an air supply port and multiple air outlets. The air supply port is connected to the exhaust port of the inflatable unit 24, and the air outlet is respectively connected to the multiple airbags 25 through pipes 251. The air separator 241 can control the connection or interruption of the air supply port and the air outlet. When the inflatable unit 24 transports air into the inflatable heating device 2, the air can enter the air separator 241 through the air port, and then the heated air is transported to the multiple airbags 25 through the pipes 251 from the multiple air outlets. Of course, the first air inlet is also connected to different airbags 25 through multiple pipes 251, so that when in the circulating heating state, the inflation unit 24 can circulate and heat multiple airbags 25 at the same time.

[0047] Furthermore, the air volume in different airbags 25 can be controlled by the air separation valve 241. It is only necessary to set the preset air pressure in each airbag 25 in advance. When the air pressure in the airbag 25 reaches the preset value, the air separation valve 241 can disconnect the air supply port and the air outlet. This method can improve the comfort of the inflatable heating blanket. Medical staff can adjust the air pressure in different airbags 25 according to the patient's use experience, so that the inflatable heating blanket has better fit and wrapping.

[0048] In order to facilitate the use of the heating management device 1 by medical staff, the inflatable heating device 2 is managed uniformly. Figure 1 and Figure 2 In one embodiment provided in the present application, after the connector 21 is connected to the interface 11, the first control unit 22 can adjust the heating temperature of the heating unit 23 and the inflation flow of the inflation unit 24 through the second control unit 12. The first control unit 22 responds to the operation instruction of the medical staff, and then outputs the control signal to the second control unit 12, and the second control unit 12 can control the heating unit 23 and the inflation unit 24 according to the control signal, thereby achieving the effect of controlling the heating temperature and the inflation flow. When it is necessary to change the air pressure in different airbags 25, it is also achieved through the above control method.

[0049] In a specific embodiment, the inflatable heating device 2 includes a sensor assembly; the sensor assembly is connected to the first control unit 22 to feed back sensing data; the second control unit 12 obtains the sensing data to adjust the heating temperature and the inflation flow of the inflatable heating device 2. The sensor assembly includes a temperature sensor and a pressure sensor, the temperature sensor and the pressure sensor are respectively arranged in the airbag 25, and the sensing data includes temperature data and pressure data of the airbag 25.

[0050] In summary, in the technical solution provided by the present application, the heating management device can not only provide power for the inflatable heating device, but also manage the inflatable heating device. This method of separating the power supply device and the management device is beneficial to reducing the size of the inflatable heating device, and it is more convenient for medical staff to use it. At the same time, it is also convenient to combine this inflatable heating device with other types of heating devices. In addition, multiple interfaces with the same specifications can not only supply power to multiple inflatable heating devices at the same time, but also centrally manage multiple devices, which is convenient for the management of multiple devices and more efficient.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
