Description

Technical Field

[0001] This application relates to the field of medical devices, and particularly to a medical warming system and a warming unit. Background Art

[0002] With the continuous progress of medical standards, hospitals are equipped with various medical devices to monitor patients' physical indicators in detail, such as the five vital signs of life: body temperature, blood pressure, pulse, respiration, and pain. Maintaining a constant body temperature is a necessary condition for ensuring the body's metabolism and normal vital activities, while abnormal body temperature can cause metabolic disorders and even endanger life. Therefore, clinically, it is very important to manage the body temperature of patients and, when the body temperature is low, to keep warm in a timely manner through a warming unit.

[0003] Currently, there are multiple types of warming units used in hospitals, such as blood transfusion and infusion warmers, electric heating blankets, air heating blankets, foot heating blankets, etc. Different warming units can only meet the heating problems in certain situations. In an actual clinical environment, it is often necessary to use different warming units to solve multiple warming problems simultaneously. To facilitate the management of multiple warming units at the same time, it is also necessary to connect multiple devices to the control device at the same time. However, since the interface types of different warming units are different, the control device needs to be equipped with multiple connection joints at the same time, which is not only inconvenient to use, but also the manufacturing cost of the control device is higher.

"Substantially" means 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.

[0046] Nowadays, with the development of medical technology, more and more medical devices are used in the monitoring of patients' vital signs. The normalcy of the five major vital signs, namely body temperature, blood pressure, pulse, respiration, and pain, is a necessary condition for patients to ensure the body's metabolism and normal life activities. Since the abnormality of a patient's body temperature can lead to metabolic disorders and even endanger life, the monitoring of a patient's body temperature is particularly important. The core body temperature of a normal person is 36.5°C to 37.5°C, and the surface body temperature is about 33°C. The core body temperature refers to the temperature of the important organs deep in the body, corresponding to the surface body temperature, and the temperature gradient between the two is about 2°C to 4°C. The phenomenon that the core body temperature of the body is lower than 36°C due to various reasons during the perioperative period is called perioperative hypothermia, also known as accidental perioperative hypothermia, which should be distinguished from controlled hypothermia for medical purposes. Nowadays, we already have quite good conditions to implement perioperative temperature management. For example, the body temperature of the patient can be measured in real time through detection equipment, and when the patient's body temperature is low, the patient can be kept warm through a warming unit to prevent the body temperature from dropping to a dangerous value.

[0047] However, the existing warming units are usually used in conjunction with control equipment to facilitate the centralized management of various warming units. Usually, these warming units are pluggable and connectable to the control equipment through electrical connectors. However, due to the different voltages, powers, and interfaces of different warming units, different fixed ports must be reserved on the control equipment, and the number of different ports must also be fixed. This method is not only inconvenient to use, but also the manufacturing cost of the control equipment is higher. To solve these problems, this application provides a medical warming system and a connector.

[0048] See Figures 1 to 3 , in an embodiment of this application, a medical warming system is provided. The medical warming system includes: at least one warming unit 2, a control device 1, and a connector 3. The control device 1 is provided with a plurality of identical mounting ports 101. The connector 3 is connected to the warming unit 2, and the connector 3 can also be detachably connected to the mounting port 101. When the connector 3 is connected to one of the mounting ports 101 on the control device 1, the warming unit 2 can be electrically connected to the control device 1. [[ID=IO]]

[0049] When the medical warming system includes multiple warming units 2, the connectors 3 on different warming units 2 can all be matched and connected to any mounting port 101; after the connector 3 is connected to one of the mounting ports 101, the control device 1 can identify the type of the warming unit 2 on the connector 3 and provide an adapted power supply for the warming unit 2. The adapted power supply can be understood as a power supply whose voltage, current, or power meets the requirements of the warming unit 2.

[0050] Furthermore, in an embodiment of the present application, a medical warming system is provided. The medical warming system includes: at least one warming unit 2, a control device 1, and a connector 3. The connector 3 is used to connect the warming unit 2 to the control device 1. The connection between the warming unit 2 and the control device 1 includes not only mechanical connection, but also electrical connection and communication connection. The control device 1 is connected to one or more warming units 2 and is used to provide an appropriate power supply for the warming unit 2. When the warming unit 2 is connected to the control device 1, the control device 1 can identify the type of the warming unit 2, and thus output electrical energy with corresponding power to meet the normal operation of the warming unit 2.

[0051] To improve the convenience and flexibility of the medical warming system, the warming unit 2 is detachably connected to the control device 1 through the connector 3. Specifically, the connector 3 includes a first connector 31 and a second connector 32. The first connector 31 and the second connector 32 can be cooperatively connected. At least one first connector 31 is arranged in the mounting opening 101 of the control device 1, and the second connector 32 is arranged on the warming unit 2. When the warming unit 2 needs to be used, only the second connector 32 on the warming unit 2 needs to be connected to the first connector 31 on the control device 1, or the warming unit 2 is connected to any one of the mounting openings 101 on the control device 1 through the connector 3. After the control device 1 identifies the type of the warming unit 2, it can output appropriate electrical energy to provide the heat required for the warming unit 2 to generate heat.

[0052] See Figure 1 and Figure 2 , in an embodiment provided by the present application, the first connector 31 is detachably connected to the control device 1. A plurality of mounting openings 101 are provided on the device body of the control device 1, and the first connector 31 can be inserted into the mounting opening 101. When the first connector 31 is connected to the control device 1, the tail end of the first connector 31 is inserted into the device body, and the head end of the first connector 31 is located outside the device body, so as to facilitate the cooperative connection between the second connector 32 and the first connector 31. Specifically, any first connector 31 can be detachably connected to any mounting opening 101, and the second connector 32 on any warming unit 2 can be connected to the first connector 31 adapted in any mounting opening 101. A plurality of identical or different warming units 2 can be connected in parallel to the control device 1 through a plurality of first connectors 31. For example, a plurality of first connectors 31 on the control device 1 are respectively connected to a warming unit 2, and the control device 1 supplies power to a plurality of warming units 2 in parallel at the same time.

[0053] In another embodiment, any first connector 31 can be detachably connected to any mounting port 101. However, the second connectors 32 on different heating units 2 each have a first connector 31 adapted thereto, and the second connector 32 on a certain heating unit 2 can only be connected to the adapted first connector 31. Multiple identical or different heating units 2 can be connected in parallel to the control device 1 through multiple adapted first connectors 31.

[0054] In order to satisfy the control device 1 to supply power to the heating unit 2 and at the same time the control device 1 can receive the data signal output by the heating unit 2. The connector 3 includes a power contact and a data contact. The power contact is used to supply power to the heating unit 2, and the data contact is used to identify the type of the heating unit 2. Specifically, the first connector 31 and the second connector 32 respectively include a plurality of power contacts and a plurality of data contacts. When the first connector 31 and the second connector 32 are cooperatively connected, the plurality of power contacts are cooperatively docked, and the plurality of data contacts are also cooperatively docked, so as to realize the power supply and data transmission between the control device 1 and the heating unit 2.

[0055] Furthermore, when the medical heating system includes multiple types of heating units 2, the second connectors 32 on different heating units 2 are the same. It can be understood that the second connectors 32 on different heating units 2 are the same, and different heating units 2 can all be connected to the control device 1. When there are multiple first connectors 31 provided on the control device 1, the specifications of the multiple first connectors 31 are also the same, and any heating unit 2 can be arbitrarily connected to one of the adapted first connectors 31.

[0056] In the technical solution provided by the present application, the second connectors 32 on different types of heating units 2 are the same, and multiple identical first connectors 31 are detachably arranged on the control device 1. Any heating unit 2 can be arbitrarily connected to any first connector 31 on the control device 1. After the first connector 31 and the second connector 32 are connected, the control device 1 can accurately identify different heating units 2, so as to provide a current with an adapted power for the heating unit 2. The structures and specifications of the first connector 31 and the second connector 32 are unified, which is not only more convenient to use, and multiple types of heating units 2 can arbitrarily select the first connector 31 for connection. In addition, using standardized connectors also facilitates the user's management of multiple types of heating units 2.

[0057] It should be noted that for the convenience of using the heating unit 2, the heating unit 2 further includes a cable 33. One end of the cable 33 is connected to the heating unit 2, and the other end is connected to the second connector 32. The cable 33 includes multiple wire cores, and some of the wire cores are connected to the power contacts, and some of the other wire cores are connected to the data contacts. And the first interface on the control device 1 can be directly provided on the control device 1 or can be connected to the control device 1 through the cable 33.

[0058] SeeFigure 4 and Figure 5 In an embodiment provided by the present application, a first connector 31 is further provided on the heating unit 2, and a plurality of heating units 2 can be connected in series, and one of the heating units 2 is connected to the control device 1. Specifically, a second connector 32 and at least one first connector 31 are provided on the heating unit 2. The second connector 32 is used to connect to the first connector 31 on the control device 1, and the first connector 31 on the heating unit 2 is used to connect to the second connector 32 on other heating units 2. It can be understood that after a plurality of heating units 2 are connected in series, then one of the heating units 2 is connected to the control device 1. This technical solution is not only convenient for the arrangement and use of various heating units 2, but also convenient for the management of various heating units 2.

[0059] During the use of various heating units 2, they may be connected in series at the same time. The connector 3 between the heating unit 2 and the control device 1 will surely bear the power of all heating units 2. Therefore, in the technical solution provided by the present application, the current power that the connector 3 can bear is configured according to the total power of all types of heating units 2.

[0060] The types of the heating unit 2 include but are not limited to: blood transfusion and infusion warmer, electric heating blanket, air heating blanket, foot heating blanket, arm blanket, etc.

[0061] The following describes the medical heating system provided by the present application in detail through specific usage scenarios. For example, a plurality of first connectors 31 with the same specifications are provided on the control device 1. When a patient needs to use a blood transfusion and infusion warmer, only need to connect the connector 3 on the blood transfusion and infusion warmer to any one of the mounting ports 101 on the control device 1. After the control device 1 recognizes that the heating unit 2 is a blood transfusion and infusion warmer, it can provide an adapted power supply for the blood transfusion and infusion warmer. When the patient needs to use a blood transfusion and infusion warmer, an electric heating blanket, and a foot warmer at the same time, connect the connectors 3 of these several heating units 2 to different mounting ports 101 respectively. After the control device 1 recognizes the types of different heating units 2, it can output adapted power supplies through the connectors 3 respectively to meet the normal working requirements of different heating units 2.

[0062] For another example, when there is a first connector 31 on the control device 1 and this patient needs to use a blood transfusion and infusion warmer, an electric heating blanket, and a foot warmer at the same time. First, connect the second connector 32 of the electric heating blanket to the first connector 31 in one of the mounting ports 101 of the control device 1, then connect the foot warmer in series to the first connector 31 on the electric heating blanket, and then connect the blood transfusion and infusion warmer in series to the first connector 31 on the foot warmer. After the control device 1 detects the quantity and types of the heating units 2, it can output a power supply with adapted power through the first connector 31, which can effectively prevent excessive power output.

[0063] See Figure 5 , in an embodiment provided by the present application, the medical warming system further includes a docking station 4. A second connector 32 and multiple first connectors 31 are provided on the docking station 4. The second connector 32 can be cooperatively connected to the first connector 31 on any warming unit 2 or the first connector 31 in any mounting port 101 on the control device 1. The multiple first connectors 31 on the docking station 4 can be used to connect to multiple warming units 2. Specifically, when the docking station 4 is connected to the control device 1, multiple warming units 2 can be connected in parallel to the control device 1 through the docking station 4. When the docking station 4 is connected to one type of warming unit 2, multiple other same or different warming units 2 can be connected in series to this type of warming unit 2 at the same time.

[0064] To facilitate the management of the warming units 2 connected to the control device 1, a switch assembly is provided on the control device 1. The first connector 31 on the control device 1 is connected in series with the switch assembly to control the on-off of the first connector 31. When there are multiple first connectors 31 on the control device 1, the control device 1 also includes multiple switch assemblies at the same time. One first connector 31 is connected in series with one switch assembly, and the warming units 2 connected to the control device 1 can be freely controlled through the switch assembly.

[0065] See Figure 3 , Figure 12 and Figure 13 , in an embodiment of the present application, a warming unit 2 is provided. This warming unit is applicable to the above-mentioned medical warming system. The warming unit 2 includes: a device body 20, a heating component, a control unit, and a second connector 32. The heating component is provided on the device body 20 and can be used to heat up when power is supplied. The control unit is located on the device body 20 and is electrically connected to the heating unit. The second connector 32 is electrically connected to the control unit, and the second connector 32 can be detachably connected to a matching first connector 31. The first connector 31 can be detachably connected to any one of multiple identical mounting ports 101 on the control device 1.

[0066] When the first connector 31 that is matingly connected to the second connector 32 is connected to one of the mounting ports 101, the control unit is electrically connected to the control device 1, and the control device 1 can identify the type of the warming unit 2 connected to the mounting port 101 and provide a matching power supply for the warming unit 2.

[0067] In another embodiment, the heating unit 2 includes a control unit 18 and a heating component (not shown in the figure). The heating component is connected to the control unit. The control unit is used to control the heating of the heating component and is also connected to the first connector 31 and the second connector 32. Specifically, the control unit can control the heating component to start heating or stop heating. For example, when the temperature of the heating unit 2 is too high, the control unit can turn off the heating component or intermittently start and stop the heating component so that the heating unit 2 can provide an appropriate heating temperature.

[0068] The control unit is respectively connected to the power supply contact and the data contact on the connector 3. After the heating unit 2 is connected to the control device 1, the control unit can cut off or connect the power supply provided by the power supply contact, thereby starting or turning off the heating component. In addition, the control unit can also transmit various signals to the control device 1 through the data contact. The various signals include the identification code (device ID) of the heating unit 2, which facilitates the control device 1 to identify the type of the heating unit 2.

[0069] Further, when multiple heating units 2 are connected in series, the control units on the multiple heating units 2 are also connected in series at the same time. The control power supplies on different heating units 2 can respectively transmit various signals to the control device 1. The control device 1 can determine the number and type of the connected devices according to the identification codes of the heating units 2 sent by different control units, and thus output a power supply with an adapted power, effectively preventing the power of the output power supply from being too large.

[0070] For each type of heating unit 2, in addition to heating, temperature measurement is also required to ensure that the heated part of the heating unit 2 reaches the set temperature. To ensure that the heating unit 2 can provide an accurate heating temperature, the heating unit 2 also includes a plurality of detection units 19. The detection units 19 are connected to the control unit 18 through leads and are used to detect the temperature of the heating unit 2. The control unit 18 adjusts the heating of the heating component based on the temperature data detected by the detection units 19. When multiple heating units 2 are simultaneously connected to the control device 1, the temperature data detected by the detection units 19 can be transmitted to the control device 1 in real time to meet the need for data recording and backup. In addition, when multiple heating units 2 are connected in series or simultaneously connected in parallel to the control device 1, the data between different heating units 2 can be shared, thereby realizing more accurate regulation of the heating temperature by the heating unit 2.

[0071] However, since the entire heated part often has a relatively large area, considering the heating uniformity, multiple temperature sensors are often provided on the heating unit 2. For the heating unit 2 with a large heating area, a plurality of detection units 19 are provided on the heating unit 2. Different detection units 19 can detect the temperature of different areas on the heating unit 2. The multiple detection units 19 are simultaneously connected in parallel to the control unit 18.

[0072] See Figure 12 , in an embodiment provided by the present application, a plurality of detection units 19 and a heating component are respectively electrically connected to a control unit 18. The control unit 18 exchanges data with a control device through a connector, and the exchanged data at least includes temperature data and control signals. When multiple heating devices are connected in parallel to the control device, the control device can simultaneously obtain the temperature values detected by the plurality of detection units 19 on the multiple heating units 2. When the multiple heating units 2 are connected in series to the control device, the control device can sequentially obtain the temperature values detected by the plurality of detection units 19 on different heating units 2 through a series circuit. In addition, the control device can also control the heating components on different heating units 2, for example, adjusting the heating temperature of the heating components.

[0073] Generally, a plurality of detection units 19 are measured by a control device 1. However, during the measurement process, each detection unit 19 has at least two connection terminals and outputs analog signals. When a plurality of detection units 19 are used simultaneously, it will result in a large number of wire harnesses in the connection cable, thus causing the volume of the connection terminals to be relatively large, and the large number of wire harnesses is also prone to interference, resulting in deviation in signal measurement. To avoid this situation, in the technical solution of the present application, by setting a control unit 18 on each heating unit 2, the control unit 18 acquires the temperature data of each detection unit 19, and then the control unit 18 uniformly sends it to the control device through a connector. Only two data cables are needed to send the temperature data of the plurality of detection units 19 to the control device, thereby effectively avoiding the situation of a large number of wire harnesses in the connection cable. Taking a medical warming blanket with a large area as an example, there are 5 temperature sensors on the warming blanket. Usually, 10 cables are required to connect to the control device. However, after setting the control unit, the temperature sensors can be respectively connected to the control unit, and then the control unit can be electrically connected to the control device through two cables. Correspondingly, the volume of the connector can also be further optimized.

[0074] The following will describe in detail the steps of how the control unit 18 acquires the temperature data of the plurality of detection units 19 and sends the temperature data to the control device 1 through specific descriptions.

[0075] See Figure 13, in an embodiment provided by the present application, the control unit 18 includes a microcontroller unit and an analog switch module. The analog switch module is electrically connected to the microcontroller unit, and multiple detection units 19 are respectively electrically connected to the analog switch. The microcontroller unit sequentially reads different detection signals of the multiple detection units 19 in a time-division multiplexing manner through the analog switch module. Specifically, the multiple detection units 19 are connected in parallel to the analog switch module. The analog switch module can sequentially read the detection signals of the multiple detection units 19, and then the analog switch module sends the detection signals corresponding to the multiple detection units 19 to the microcontroller unit in a time-division multiplexing manner. The microcontroller unit is a single-chip microcomputer or a microcontroller, etc. <s

[0076] Under normal circumstances, the control unit 18 only needs four lines to communicate with the control device, which are the positive electrode of the heating power supply (24V), the negative electrode of the heating power supply (GND), the positive signal (485+), and the negative signal (485-), respectively.

[0077] Time Division Multiplexing (TDM) is to use different time periods of the same physical connection to transmit different signals, which can achieve the purpose of multiplexing. Therefore, the analog switch module and the control unit 18 only need two signal lines to achieve communication.

[0078] Furthermore, the control unit 18 further includes a signal processing module, and the signal processing module is electrically connected to the microcontroller unit; usually, the detection unit 19 is a temperature sensor. When the temperature sensor collects the temperature in real time, it often outputs the detection signal in the form of resistance value, and this detection signal is usually an analog signal. To facilitate the control device to read the specific temperature value of each detection unit 19, the microcontroller unit also needs to convert the analog signal into a digital signal. Specifically, based on the detection signal, the microcontroller unit converts the detection signal into a temperature value signal, and then the signal processing module processes the temperature value signal.

[0079] Furthermore, since the analog switch module collects the detection signals of different detection units 19 in a time-division multiplexing manner, when the temperature value signal is output, the temperature value signal also needs to be processed so that the control device can obtain the temperature value signal of the corresponding detection unit 19. Specifically, the microcontroller unit transmits the temperature value signal to the signal processing module. After the signal processing module performs differential processing on the temperature value signal, it transmits the processed temperature value signal to the control device Ⅰ, and the control device can obtain the temperature values detected by each detection unit 19. For different heating units 2, the same technical solution is adopted for data detection and processing.

[0080] It should be noted that when multiple heating units 2 are connected in series to the control device 1, the multiple heating units 2 can also communicate and exchange data with the control device 1 through time-division multiplexing.

[0081] Furthermore, the detection signals obtained by the analog switch module from the detection unit 19 cannot be directly sent to the micro-control unit. Usually, the detection signals need to be filtered first so that they will be more accurate. In an embodiment provided in the present application, the control unit 18 further includes a filtering module; the filtering module is electrically connected to the micro-control unit and the analog switch module respectively, and the multiple detection signals read by the analog switch module are processed by the filtering module and then transmitted to the micro-control unit.

[0082] Furthermore, the control unit 18 further includes a heating controller, which is electrically connected to the micro-control unit and the heating component respectively. The heating controller can not only control the start and stop of the heating component, but also control the heating power of the heating component. Specifically, based on the control signal of the control device, the micro-control unit delivers a working signal to the heating controller, and the heating controller controls the heating component to generate heat and warm up according to the working signal. In a specific implementation, the micro-control unit outputs a PWM (Pulse-Width Modulation) signal to control the MOS transistor on the heating controller. The full name of MOS transistor is MOSFET (Metal Oxide Semiconductor Field Effect Transistor), which is a semiconductor device that controls current through the electric field effect. Thus, the current power output by the heating controller to the heating component is changed.

[0083] As mentioned above, when the heating unit 2 is connected to the control device, the control device identifies the type of the heating unit 2. In an embodiment provided in the present application, the control unit 18 further includes an identification module, which stores the identification information of the heating unit 2. After the heating unit 2 is electrically connected to the control device, the control device is electrically connected to the identification module and obtains the corresponding identification information. The identification information includes but is not limited to: the ID number of the heating device, the type number of the heating device, the power value required by the heating device, etc.

[0084] The micro-control unit, analog switch module, signal processing module, filtering module, heating controller, identification module, etc. mentioned above can be different electrical components, and then are connected to each other through cables. They can also be different circuit modules integrated on a circuit board.

[0085] See Figures 6 to 10, in an embodiment of the present application, a connector 3 is further provided. The connector 3 is applicable to the above-mentioned medical warming system. The connector 3 includes: a first connector 31 and a second connector 32. The first connector 31 includes a first housing 51 and a plurality of first contacts 10. The second connector 32 includes a second housing 52 and a plurality of second contacts 15. The first housing 51 can be cooperatively connected with the second housing 52, and the plurality of first contacts 10 are correspondingly connected to the plurality of second contacts 15. The plurality of first contacts 10 and the plurality of second contacts 15 respectively include power contacts and data contacts.

[0086] Furthermore, the first housing 51 of the first connector 31 is detachably connected to the control device 1. It can be detachably connected to the control device 1 through fasteners or by means of plugging.

[0087] See Figure 6 and Figure 7 , taking the number of contacts on the connector 3 as six as an example, the six contacts are arranged in two rows and three columns. Among them, the two contacts in the first column are the positive poles of the power contacts, the two contacts in the second column are the data contacts, and the two contacts in the third column are the negative poles of the power contacts. It should be noted that the present application does not specifically limit the number and arrangement form of the contacts on the first connector 31 and the second connector 32, and the number and arrangement form of the contacts on the first connector 31 and the second connector 32 match each other.

[0088] For the convenience of connecting the first connector 31 and the second connector 32, a first docking portion 8 is provided on the first housing 51, and a second docking portion 14 is provided on the second housing 52. The first docking portion 8 can be cooperatively connected with the second docking portion 14. Specifically, the first connecting portion and the second connecting portion can ensure the accuracy of the docking of the first connector 31 and the second connector 32 and prevent the connector 3 from being connected reversely.

[0089] In a specific embodiment, the plurality of first contacts 10 on the first connector 31 are plug holes; the plurality of second contacts 15 on the second connector 32 are plug posts. The plug posts can be plugged into the plug holes to realize the connection between the first connector 31 and the second connector 32. The first housing 51 includes a first docking seat 7 and a first outer shell 6. A groove 11 is provided between the first inner shell and the first outer shell 6, so that the first docking seat 7 and the first outer shell 6 are separated from each other. The plurality of contacts (plug holes) are arranged on the first docking seat 7, and the first docking portion 8 is located in the groove 11. The second housing 52 includes a second docking seat 13 and a second outer shell 12. The second outer shell 12 is provided on the periphery of the second docking seat 13. The plurality of contacts (plug posts) are arranged on the second docking seat 13, and the second connecting portion is located on the second outer shell 12. When the first connector 31 and the second connector 32 are cooperatively connected, the plurality of plug posts are plugged into the plug holes, and the second outer shell 12 is cooperatively plugged into the groove 11, and the first docking portion 8 and the second docking portion 14 are correspondingly connected.

[0090] To make the connection between the first connector 31 and the second connector 32 more stable and improve the adaptability of the connector 3 in various environments. Refer to Figures 6 to 10 , a plurality of first limiting parts 9 are provided on the outer wall of the first housing 51, and a plurality of second limiting parts 16 are provided on the outer wall of the second housing 52. The first limiting parts 9 and the second limiting parts 16 can be cooperatively and locked. In a specific embodiment, two first limiting parts 9 are symmetrically provided on the outer wall of the first housing 51, and two second limiting parts 16 are symmetrically provided on the outer wall of the second housing 52. Through holes 17 are respectively provided on the first limiting parts 9 and the second limiting parts 16. After the first connector 31 and the second connector 32 are cooperatively connected, the first limiting parts 9 and the second limiting parts 16 on the same side are aligned. At this time, the U-shaped pins can respectively pass through the through holes 17 on the first limiting parts 9 and the second limiting parts 16, so as to lock and connect the first connector 31 and the second connector 32.

[0091] Refer to Figure 1 , for the convenience of users, the control device 1 further includes a plurality of control buttons, indicator lights, a display screen, a speaker and other devices. To meet the linkage of multiple control devices 1, different control devices 1 can also be communicatively connected by wired or wireless means. For example, the control devices 1 used in different wards can be directly connected to the hospital's central control system or to the devices in the cloud, so as to facilitate the user to uniformly monitor at the terminal.

[0092] The display screen on the control device 1 can be used to display various information, such as the connection status of the heating unit, the power output to the heating unit, the type and quantity of the heating unit, the real-time temperature of the heating unit, prompt information, etc.

[0093] In a specific embodiment, the display screen can simultaneously display the types of devices corresponding to different first connectors 31, the specific power values output by different first connectors 31, and the real-time temperatures of different heating units 2 corresponding to different first connectors 31. When one of the heating units 2 is disconnected from the control device 1, the display screen can also display prompt information, such as "The electric heating blanket of the first interface is disconnected". In addition, when the heating unit 2 is abnormal or the temperature is too high, the display screen can also display relevant prompt information.

[0094] In another embodiment of the present application, an electrical connector (not shown in the figure) is also provided. The electrical connector is applicable to a control device and a variety of heating units. The electrical connector includes a first connector and a second connector, and the second connector is detachably inserted into the first connector. The first connector is disposed on the control device and includes a first housing and a plurality of first contacts. The plurality of first contacts are disposed in the insertion cavity of the first housing. The number of the first contacts is greater than or equal to three. When the number of the first contacts is three, one of the first contacts is the positive electrode, another first contact is the negative electrode, and the last first contact is the ground electrode.

[0095] Three power connection terminals are provided at the tail end of the first housing for connecting to the power supply line, and the three power connection terminals are respectively connected to different first contacts. For example, the first power connection is connected to the first first contact, the second power connection terminal is connected to the second first contact, and the third power connection terminal is connected to the third first contact. The three different power connection terminals are respectively connected to different circuits on the control device (for example: neutral wire, live wire and ground wire).

[0096] The second connector is disposed on the heating unit and is connected to the heating unit through a power line. The first connector includes a second housing and a plurality of second contacts. The plurality of second contacts are disposed in the insertion cavity of the second housing, and the plurality of second contacts are used for connecting different power lines on the heating unit. For example, some of the second connection terminals are used for connecting to the neutral wire of the power line, another part of the second connection terminals are used for connecting to the live wire of the power line, and the remaining second connection terminals are used for connecting to the ground wire of the power line. Of course, if some heating units do not need to be provided with a ground wire, some of the second connection terminals can be connected to the neutral wire of the power line, and another part of the second connection terminals can be connected to the live wire of the power line. The present application does not make specific limitations on this.

[0097] If the heating unit needs to exchange data with the control device, it can be achieved through power line communication (carrier communication). Modems are respectively provided on the heating unit and the control device for analyzing signals. Of course, some of the plurality of second contacts on the second connector can also be connected to signal lines to meet the communication between the heating unit and the control device. In addition, a wireless communication module can also be provided on the heating unit and the control device to achieve communication.

[0098] Furthermore, the number or length of the second contacts on different second connectors is different. When the second connector is inserted and connected to the first connector, all or part of the second contacts are connected to the first contacts. The second connector with different numbers or lengths of second contacts can be configured for the heating unit that requires different voltages or powers. For example, when a heating unit with a higher voltage or greater power is needed, when the second connector it is configured with is connected to the first connector, more second contacts will be connected to the first contacts on the first connector, thus meeting the requirement for carrying a greater voltage or power, and effectively preventing the heating or damage of the electrical connector. In addition to differentiating different second connectors by changing the number of second contacts, it can also be achieved by changing the length of the second contacts. For example, the number of second contacts on the second connectors adapted to two heating units with different powers is the same, but the length of some of the second contacts on the second connector adapted to the heating unit with a lower power is shorter. When the first connector is connected to the second connector, some of the second contacts with shorter lengths cannot be connected to the first contacts, and only the second contacts with longer lengths can be connected to the first contacts on the first connector.

[0099] In the technical solution provided by the embodiment of the present application, the number or length of the second contacts on different second connectors is different. When different second connectors are connected to the first connector, all or part of the second contacts are connected to the first contacts. Thus, multiple heating units can be connected to the control device through a single form of the first connector. Only multiple first connectors of a single form need to be configured on the control device, which not only facilitates the connection of multiple second connectors but also makes it more convenient for users to use.

[0100] Furthermore, the cross-sectional shape of the insertion cavity of the first housing includes, but is not limited to, circular, square, and polygonal. The cross-sectional shape of the plug connector matches the cross-sectional shape of the insertion cavity of the first housing. The cross-sectional shape of the insertion cavity on the second housing is related to the arrangement shape of the multiple second contacts and the arrangement form of the multiple first contacts. When the multiple first contacts are arranged in a ring, the cross-sectional shape of the insertion cavity on the second housing is circular.

[0101] To improve the regularity and structural compactness of the electrical interface, the multiple first contacts and the multiple second contacts are respectively arranged in a circular array. In addition, when the electrical connector is square, the multiple first contacts can also be arranged in a row.

[0102] To improve the safety performance of the first contacts, the first contacts include an insulating shell and a metal inner sleeve. The metal inner sleeve is disposed in the insertion hole of the first contact, and the height of the metal inner sleeve is less than the height of the insulating shell. It can be understood that the metal inner sleeve is recessed in the insulating shell, thus effectively avoiding the direct exposure of the metal and reducing the occurrence of accidents such as electric shock and short circuit.

[0103] In the technical solution of the present application, by providing different second connectors on different heating units, the purpose that the control device can identify different heating units is achieved. However, when the number of heating units further increases, changing the number and length of the second contacts cannot meet the usage requirements.

[0104] In an embodiment provided by the present application, the first connector further includes a detection sensor, different second connectors are provided with different sensing elements, and the detection sensor can identify different sensing elements. Specifically, the second sensors on different heating units can be the same or different, but the sensing elements on different heating units are different. When the first connector is connected to the second connector, the detection sensor on the first connector can identify the specific data of the sensing element (such as the ID number of the device), so as to determine the type of the heating unit, and then the corresponding voltage or power can be output. Since the maximum power of different heating units is different, the control device can calculate the current output power that can be achieved according to the heating unit, preventing the output power from being too large and exceeding the output capacity of the control device.

[0105] See Figure 1 , Figure 2 and Figure 11 , in an embodiment of the present application, a working method of a medical heating system is further provided. The working method is applicable to the control device of the medical heating system in any of the above embodiments. The working method includes the following steps:

[0106] S101, based on the connection signal between the first connector and the mounting port, obtain the identification information of the heating unit;

[0107] S102, according to the identification information, output a current with an adapted power to the corresponding first connector.

[0108] Since different heating units 2 operate at different powers, after the heating unit 2 is connected to the control device 1, the control device 1 needs to promptly identify the type of the heating unit 2, and then can correspondingly output a current with an appropriate power. In step S101, when the first connector 31 and the second connector 32 are connected and the first connector 31 is then connected to the installation port 101 of the control device 1, the control device 1 can promptly receive the identification information of the heating unit 2, and this identification information can be the identification ID of the heating unit 2. Specifically, it can be achieved in the following way. After the first connector 31 is connected to the installation port 101, the data contacts on the first connector 31 are also connected to the data contacts on the second connector 32 simultaneously, thereby connecting the control device 1 to the control unit on the heating unit 2. The connection signal of the first connector 31 and the second connector 32 will trigger the control unit to start, and then the control unit can send the identification ID of the corresponding heating unit to the control device 1. The control device 1 determines the type of the heating unit 2 according to the identification ID of the heating unit 2, and then correspondingly outputs a current with a power adapted to the heating unit.

[0109] When multiple first connectors 31 on the control device 1 are respectively connected to different heating units 2, the control device 1 can respectively identify the types of the heating units 2 connected to each first connector 31, and correspondingly output a current with a power adapted to the heating unit 2 through the first connector 31.

[0110] When one of the first connectors 31 on the control device is connected in series with multiple heating units 2, different heating units 2 can send the corresponding identification IDs to the control device 1 through the series circuit. Then the control device 1 can determine the number and types of the heating units 2 connected in series on the first connector 31, and then output a current with an adapted total power.

[0111] In an embodiment provided by the present application, the heating unit 2 is provided with multiple detection units, and the detection units are used to detect the temperature information in different regions of the heating unit 2; in addition, the working method of the medical heating system further includes the following steps:

[0112] S103, receiving the temperature numerical signal detected by the detection unit;

[0113] S104, adjusting the heating power of the heating unit based on the temperature numerical signal.

[0114] As the ambient temperature and the patient's body temperature change continuously, the power of the heating unit 2 also needs to change continuously to keep the temperature of the object being heated within the required range. When the heating unit 2 is heating, the detection unit can collect the temperature value of the heating unit 2 in real time, convert the temperature value into a temperature numerical signal, and then output the temperature numerical signal to the control device through the circuit connected to the control device. The control device 1 can adjust the current power output by the corresponding circuit or the heating power of the heating unit 2 according to the temperature numerical signal.

[0115] When different heating units 2 are respectively connected in parallel to different first connectors 31 of the control device 1, the control device 1 can respectively receive the temperature signals of the heating units 2 corresponding to different first connectors 31 and separately control the current power adapted to each circuit, so that each heating unit 2 can meet the usage requirements. When multiple different heating units 2 are connected in series to one first connector 31 on the control device 1, the control device 1 can also receive the temperature signals of each heating unit 2 through the series circuit and output the current with the adapted power correspondingly.

[0116] Furthermore, the heating unit also includes a control unit, and multiple detection units are respectively electrically connected to the control unit; the control unit further includes a micro-control unit and an analog switch module, the analog switch module is electrically connected to the micro-control unit, and multiple detection units are respectively electrically connected to the analog switch; step S103 "Receiving the temperature numerical signal detected by the detection unit;" further includes the following steps:

[0117] S1031, the analog switch module sequentially reads the detection signals of multiple said detection units;

[0118] S1032, the micro-control unit sequentially obtains multiple said detection signals in a time-division multiplexing manner through the analog switch module.

[0119] In the above steps, multiple detection units are simultaneously connected in parallel to the analog switch module, and the micro-control unit can obtain the signals detected by multiple detection units in a time-division multiplexing manner through the analog switch module. The time-division multiplexing method can effectively reduce the number of cables and simplify the structure of the control unit.

[0120] In an embodiment provided by the present application, the control unit further includes a signal processing module, and the signal processing module is electrically connected to the micro-control unit; the working method of the medical heating system further includes the following steps:

[0121] S105, multiple said detection units sequentially obtain the detection signals corresponding to the temperature, send the detection signals to the micro-control unit, and the micro-control unit converts the detection signals into temperature numerical signals;

[0122] S106. The signal processing module receives the temperature numerical signal;

[0123] S107. Based on a preset algorithm, the signal processing module performs differential processing on the temperature numerical signal;

[0124] S108. Output the processed temperature numerical signal to the control device.

[0125] In the above steps, the detection signal is mainly converted into a temperature numerical signal by a microcontrol unit. Usually, the detection signal is an analog signal, while the temperature numerical signal is a digital signal.

[0126] In the above text, the analog switch module sequentially obtains the detection signals detected by multiple detection units. The microcontrol unit then obtains multiple detection signals in a time-division multiplexing manner through the analog switch module. After converting the detection signals into temperature numerical signals, the signal processing module is also required to perform differential processing on the multiple converted temperature numerical signals. Subsequently, the processed temperature numerical signal is output, and the control device can obtain the temperature numerical signal detected by the corresponding detection unit.

[0127] In the technical solution provided by the present application, a plurality of first connectors with unified specifications can be arranged on the control device. A variety of different heating units are configured with different second connectors. Any second connector can be randomly inserted into any first connector, so as to realize the control device to supply power to the heating unit. In specific applications, when the patient's body temperature is low and the patient is receiving infusion, a blood transfusion and infusion warmer needs to be used at this time to warm the therapeutic liquid, so as to prevent the patient's body temperature from further decreasing. The nurse only needs to randomly insert the second connector on the blood transfusion and infusion warmer into any first connector on the control device. The control device can automatically identify the device type and then provide a power supply with appropriate voltage or power. If the patient's body temperature further decreases, the patient needs to use an electric heating blanket for warming. The nurse only needs to insert the second connector of the electric heating blanket into the idle first connector on the control device. Since the power of the electric heating blanket is greater, after the first connector recognizes the second connector of the electric heating blanket, it can automatically output the required voltage and power to meet the use requirements.

[0128] By unifying the specifications of the interfaces, the use of the heating unit can be made more flexible, and it is also more convenient and fast for the heating unit to be connected to the control device. In addition, it is also more convenient for medical staff to uniformly manage various heating units.

[0129] 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 them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
