Fig. 4 is a schematic diagram of a hardware structure of the data processing apparatus in fig. 2 according to an embodiment of the present disclosure. In this embodiment, the data processing apparatus 60 may include a memory 602, a third communication interface 604, a fourth communication interface 606, and a processor 500 connected to the memory 602, the third communication interface 604, and the fourth communication interface 606 through a bus 608.

The Processor 600 may be a Central Processing Unit (CPU), other general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf Programmable Gate Array (FPGA) or other Programmable logic device, discrete Gate or transistor logic, discrete hardware components, etc. The general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, which is the control center for the data processing device 60 and which is connected to various portions of the overall data processing device 60 by a bus 608.

The memory 602 may be used to store computer programs and/or modules, and the processor 600 implements various functions of the data processing apparatus 60 by running or executing the computer programs and/or modules stored in the memory 602 and invoking data stored in the memory 602. The memory 602 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required for at least one function, and the like. In addition, the memory 602 may include high speed random access memory, and may also include non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a Smart Media Card (SMC), a Secure Digital (SD) Card, a Flash memory Card (Flash Card), at least one magnetic disk storage device, a Flash memory device, or other volatile solid state storage device.

In this embodiment, the third communication interface 604 of the data processing device 60 can be connected to the second communication interface 506 of the identification device 50, the first communication interface 504 of the identification device 50 can be connected to the external medical equipment 30, and the fourth communication interface 606 of the data processing device 60 can be electrically connected to the main monitoring equipment 70. The data processing apparatus 60 may have a predetermined number of third communication interfaces 604, such as a predetermined number of third communication interfaces 604 equal to the number of the identification apparatuses 50, so that each identification apparatus 50 may be electrically connected to one third communication interface 604 of the data processing apparatus 60, and the data processing apparatus 60 may access a plurality of identification apparatuses 50 simultaneously. For example, the access control device 80 may include 3 identification devices, which are a first identification device, a second identification device and a third identification device, respectively, and the data processing device 60 may also include 3 third communication interfaces 604, which are electrically connected to the first identification device, the second identification device and the third identification device, respectively.

In this embodiment, after the data processing device 60 is powered on, the processor 500 may detect whether the third communication interface 604 is connected to the second communication interface 504 of at least one identification device. When the third communication interface 604 of the data processing device 60 is connected to at least one second communication interface 504, the processor 600 of the data processing device 60 can detect the connection signal and can transmit the acquisition request to the identification device 50. In an embodiment, the data processing apparatus 60 may periodically detect the connection status of each third communication interface 604 after powering on, that is, the data processing apparatus 60 may detect whether there is a connection signal at each third communication interface 604 every first predetermined time.

In an application example, the main monitoring device may be a plug-in monitor, the data processing device of the access control device may be plugged into a plug-in box of the plug-in monitor (e.g., a slot sharing a parameter module of the plug-in monitor), the data processing device is connected to a plurality of identification devices through a plurality of network cables, and each identification device is plugged into different external medical devices (e.g., a ventilator, an anesthesia machine, etc.). Monitoring data of different external medical devices can be integrated into the monitor to be displayed through the access control device. Meanwhile, the integrated data can also be uploaded to a central station, an EMR system and the like through a monitor. Or, the data processing device of the access control device uploads the data to the EMR system, for example, the data processing device is connected to the EMR system through a network cable, or the integrated data is uploaded to the EMR system through a wireless transmission mode.

In one embodiment, the identification device is provided with a separate Linux system and a CPU, and identifies the type of the external medical equipment after being plugged into the external medical equipment. After the identification is successful, the data can be transparently transmitted, and the monitoring data of the external medical equipment is transparently transmitted to the data processing device (in this mode, the data passing through the identification device is directly forwarded to the data processing device without any processing). The data processing device processes the monitoring data, for example, converts the format of the monitoring data, converts the data from different devices into standard HL7 messages, and sends the messages to an information system such as an EMR (electronic management system) for storage and backup.

In this embodiment, the recognition device 50 includes a recognition mode, a setting mode and a transmission mode.

When the processor 500 of the identification means 50 receives the setting request transmitted by the data processing means 60, the identification means 50 enters the setting mode. When the recognition apparatus 50 is in the setting mode, the recognition apparatus 50 may receive a setting request including a device identification transmitted by the data processing apparatus 60, and may store the device identification included in the setting request in the memory 502.

In an embodiment, the primary monitoring device 70 may generate a setup operation according to the external medical device 30 to which the identification means 50 is connected, and control the data processing means 60 to generate the setup request according to the setup operation. For example, the primary monitoring device 70 may be a monitor that includes a display that displays a number of operational interfaces. The user may select the type of external medical device 30 to which each identifying means 50 is connected in the operation interface. Further, the primary monitoring device 70 may generate corresponding setup operations according to the type of external medical device 30 to which each identification device is connected. For example, when a first identification means in the access control device 80 accesses the anesthesia machine, the primary monitoring device 70 generates a first setup operation containing a first device identification; when a second identification means in the access control device 80 accesses the ventilator, the primary monitoring device 70 generates a second setup operation containing a second device identification; the primary monitoring device 70 generates a third setup operation including a third device identification when the infusion pump is accessible by a third identification means within the access control device 80. As such, the data processing apparatus 60, upon receiving the first setting operation, generates a setting request containing the first device identification so that the first identifying means stores the first device identification; the data processing means 60, upon receiving the second setting operation, generates a setting request containing the second device identification so that the second identifying means stores the second device identification; the data processing means 60, upon receiving the third setting operation, generates a setting request containing the third device identification so that the third identifying means stores the third device identification.

When the processor 500 of the identification device 50 receives the acquisition request transmitted by the data processing device 60, the identification device 50 enters an identification mode; when the recognition means 50 is in the recognition mode, the recognition means 50 may transmit the stored device identification to the data processing means 60. In this embodiment, when sending the acquisition request, the data processing device 60 determines whether the device identifier transmitted by the identification device 50 is received within a second preset time; if the data processing apparatus 60 does not receive the device identifier transmitted by the identification apparatus 50 within the second preset time, which indicates that the identification apparatus 50 may not return the stored device identifier, then the data processing apparatus 60 may resend the acquisition request to the identification apparatus 50 every third preset time.

When the processor 500 of the identification device 50 receives the switching request transmitted by the data processing device 60, the identification device 50 enters a transmission mode; when the recognition device 50 is in the transmission mode, the recognition device 50 turns off the recognition mode and the setting mode, and transmits the monitoring data received from the external medical equipment 30 to the data processing device 60, wherein the monitoring data of the external medical equipment 30 includes, but is not limited to, parameters, alarms and waveform information generated by the external medical equipment 30.

In this embodiment, each identification device 50 stores a corresponding device identifier; therefore, after the identification means 50 receives the acquisition request transmitted by the data processing means 60, the device identification stored therein may be returned to the data processing means 60. For example, when the first identification means receives an acquisition request from the data processing means 60, the first identification means may return the first device identifier to the data processing means 60; when the second identification means receives the acquisition request of the data processing means 60, the second identification means may return the second device identifier to the data processing means 60; when the third identifying means receives the obtaining request of the data processing means 60, the third identifying means may return the third device identification to the data processing means 60.

Step 102, controlling the data processing device to acquire the monitoring data of the external medical equipment received by the identification device.

When the data processing device 60 obtains the device identifier of the identification device 50, the data processing device 60 may transmit a switching request to the identification device 50, so that the identification device 50 transmits the accessed monitoring data of the external medical device 30 to the third communication interface 604 of the data processing device 60 through the second communication interface 506.

And 104, controlling the data processing device to process the monitoring data based on the equipment identification so as to obtain the processed monitoring data of the external medical equipment.

In this embodiment, since the communication protocols corresponding to different external medical devices 30 may be different, in order to integrate the processing modes of different external medical devices, the memory 602 of the data processing apparatus 60 may store device drivers 610 corresponding to different external medical devices 30 or device identifiers, so that the data processing apparatus 60 can process the transmission monitoring data of different external medical devices 30 by loading the corresponding device drivers, for example, perform an analysis operation to obtain the processed monitoring data of the external medical devices.

For example, the data processing apparatus 60 includes a first device driver corresponding to a first device identifier, a second device driver corresponding to a second device identifier, and a third device driver corresponding to a third device identifier. Thus, when receiving the first device identifier transmitted by the first identification device, the data processing apparatus 60 may load the first device driver, and perform an analysis operation on the monitoring data transmitted by the first identification device through the loaded first device driver to obtain the processed monitoring data. Similarly, the data processing apparatus 60 may also load the second device driver according to the second device identifier, and load the third device driver according to the third device identifier.

In one embodiment, the data processing device 60 also transmits the processed monitoring data to the primary monitoring device 70, so that the processed monitoring data can be stored, displayed or processed by the primary monitoring device 70. Since the primary monitoring device 70 may include multiple types of devices, the communication protocol for each type of device may be different. Therefore, when the data processing device 60 parses the monitoring data to obtain processed monitoring data, the device driver of the primary monitoring device 70 further encodes the monitoring data according to the type of the primary monitoring device 70, and transmits the encoded monitoring data to the primary monitoring device 70 through the fourth communication interface. For example, for the primary monitoring device of the electronic medical record, the data processing device 60 can encode the processed monitoring data into data supporting HL7 communication protocol and transmit the data to the electronic medical record device.

In an embodiment, the data processing apparatus 60 may further determine whether the third communication interface 604 is disconnected from the electrically connected second communication interface 506, and after detecting that the third communication interface 604 is disconnected from the electrically connected second communication interface 506, the data processing apparatus 60 may unload the device driver corresponding to the identification apparatus 50 of the electrically connected second communication interface 506. For example, when the connection between the third communication interface 604 of the data processing apparatus 60 and the second communication interface of the first identification device is disconnected, the data processing apparatus 60 may unload the first device driver corresponding to the first device identifier.

In an embodiment, when the data processing apparatus 60 receives the device identifier stored in the identification apparatus 50, the data processing apparatus 60 may further determine whether a device driver corresponding to the device identifier exists; when there is no device driver corresponding to the device identifier, it indicates that the data processing device 60 may not be able to parse or process the monitoring data transmitted by the identification device 50, and at this time, the data processing device 60 may send out an alert message through the primary monitoring device 70. For example, if there is no first device driver in the memory 602 of the data processing apparatus 60, when the first identification device is electrically connected to the data processing apparatus 60, since the device driver corresponding to the first device identifier stored in the first identification device is the first device driver, and there is no first device driver in the data processing apparatus 60, at this time, the data processing apparatus 60 may send out warning information (for example, display warning information of "no device driver") through the main monitoring device 70 to prompt the user to store the corresponding first device driver in the data processing apparatus 60.

The access control method obtains the processed monitoring data after the access control equipment processes the monitoring data of each external medical equipment, and the main monitoring equipment displays, stores and the like the processed monitoring data, so that the operation for processing the monitoring data of each external medical equipment is integrated in the access control equipment, the compatibility of the system is favorably improved, and the communication between the external medical equipment and the main monitoring equipment can be realized on the premise of not increasing the cost of the external medical equipment. In addition, the access control equipment can be selectively accessed to the external medical equipment and can identify the external medical equipment through the access control equipment, so that the purpose of plug and play of the access control equipment is achieved, and the access control equipment is convenient and quick.

Referring to fig. 5, a schematic diagram of a hardware structure of an electronic device according to an embodiment of the present application is shown. The electronic device 90 may include a processor 900, a memory 902, an input communication interface 904, an output communication interface 906, a display 912, and a bus 908, wherein the processor 900 exchanges data with the memory 902, the input communication interface 904, the output communication interface 906, and the display 912 through the bus 908. Of course, other hardware components may be included, which are not described in detail herein. In this embodiment, the input communication interface 904 may be a serial interface, a network interface (such as a wired network interface or a wireless network interface), and the output communication interface 906 may be a wireless interface or a wired interface.

The Processor 900 may be a Central Processing Unit (CPU), other general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf Programmable Gate Array (FPGA) or other Programmable logic device, discrete Gate or transistor logic, discrete hardware components, etc. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.

The memory 902 may be used to store computer programs and/or modules, and the processor 900 implements various functions of the electronic device 90 by running or executing the computer programs and/or modules stored in the memory 902 and by invoking data stored in the memory 902. The memory 902 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required for at least one function, and the like. In addition, the memory 902 may include a high speed random access memory device, and may also include a non-volatile memory device such as a hard disk, a memory, a plug-in hard disk, a Smart Media Card (SMC), a Secure Digital (SD) Card, a Flash memory Card (Flash Card), at least one piece of magnetic disk storage, a Flash memory device, or other volatile solid state storage.

In this embodiment, the electronic device 90 may include a plurality of input communication interfaces, such as a first input communication interface and a second input communication interface, so that the electronic device 90 may be connected to an external medical device (not shown) through the input communication interfaces (such as the first input communication interface and/or the second input communication interface) to obtain monitoring data transmitted by the external medical device. The electronic device 90 processes (e.g., parses) the monitoring data to obtain processed monitoring data, and displays the processed monitoring data on the display 912, or transmits the processed monitoring data to an information management device (e.g., a central information monitoring device, an electronic medical record device) through the input communication interface 906.

In this embodiment, the memory 902 of the electronic device 90 stores a plurality of device drivers corresponding to device identifiers, so as to analyze or process monitoring data of different types of external medical devices. The electronic device 90 includes a first device driver corresponding to the first device identifier and a second device driver corresponding to the second device identifier.

For example, the electronic device 90 may display several operation interfaces via the display 912. The user may select the type of external medical device 30 to which each input communication interface is connected in the operator interface. The electronic device 90 may generate a corresponding setting operation according to the type of the external medical device 30 accessed by each input communication interface, for example, when the first input communication interface is accessed to the anesthesia machine, the electronic device 90 generates a first setting operation including a first device identifier; when the second input communication interface is connected to the ventilator, the electronic device 90 generates a second setting operation including a second device identification. In this way, the electronic device 90 may obtain the first device identification in response to the first setting operation, and the electronic device 90 may obtain the second device identification in response to the second setting operation.

After the electronic device 90 acquires the corresponding device identifier, the electronic device 90 may load the device driver corresponding to the acquired device identifier. For example, when the first device identifier is obtained, the electronic device 90 may load the first device driver, and perform an analysis operation on the monitoring data transmitted by the anesthesia machine through the loaded first device driver to obtain correspondingly processed monitoring data; when the second device identifier is obtained, the electronic device 90 may load the second device driver, and perform an analysis operation on the monitoring data transmitted by the ventilator through the loaded second device driver, so as to obtain processed monitoring data.

Since the information management apparatus may include a plurality of types of devices, the communication protocol of each type of information management apparatus is different. Therefore, when the electronic device 90 parses the monitoring data to obtain the monitoring data, the device driver of the electronic device 90 further encodes the processed or parsed monitoring data according to the type of the information management apparatus, and transmits the encoded monitoring data to the information management apparatus through the output communication interface 906. For example, for an information management device of an electronic medical record, the electronic device 90 can encode the monitoring data into data supporting HL7 communication protocol and transmit the data to the electronic medical record device.

In an embodiment, the electronic device 90 may further determine whether the input communication interface is disconnected from the electrically connected external medical device, and after detecting that the input communication interface is disconnected from the electrically connected external medical device, the electronic device 90 may unload the device driver corresponding to the electrically connected external medical device. For example, when the connection between the first input communication interface 904 of the electronic device 90 and the anesthesia machine is disconnected, the electronic device 90 may unload the loaded first device driver.

In an embodiment, when the electronic device 90 receives the device identifier, the electronic device 90 may further determine whether a device driver corresponding to the device identifier exists; when there is no device driver corresponding to the device identifier, it indicates that the electronic device 90 may not be able to analyze the monitoring data transmitted by the identification apparatus 50, and at this time, the electronic device 90 may send an alert message through the display 912. For example, if there is no first device driver in the electronic device 902, when the anesthesia machine is electrically connected to the data processing apparatus 60, since the device driver corresponding to the anesthesia machine is the first device driver, and there is no first device driver in the electronic device 90, at this time, the electronic device 90 may send out warning information (for example, display warning information of "no device driver") through the display 912 to prompt the user to store the corresponding first device driver in the electronic device 90.

The electronic equipment can analyze the monitoring data of the external medical equipment of different types according to different equipment drivers to obtain the monitoring data, so that the compatibility of the system is improved, and the monitoring data can be obtained on the premise of not increasing the cost of the external medical equipment so as to be displayed or stored for operation.
