The medical device may be plural, and the display image is an image of a display area of the medical device. Alternatively, the display area may be a screen area, a readable area, or the like of the medical device.
In some embodiments, where the medical device has an image output interface, for example, the medical device is an electrocardiograph, having an image output interface. The display image may be acquired through an image output interface. Specifically, the image output interface of the medical equipment can be connected through the video signal connecting wire, so that the display image of the medical equipment can be obtained. Therefore, the hardware resources of the medical equipment can be fully utilized, and the display image can be rapidly acquired.
In other embodiments, where the medical device does not have an image output interface, for example, the medical device is a syringe pump, the image cannot be output without an image output interface.

It will be appreciated that the target area is an area of interest to the user, for example an area in which a particular type of display data is located. Specifically, the target area can be determined and identified in the display image according to the target area position and the target area size in the target area information, and the image data of the target area, that is, the image of the target area, can be obtained.
In some embodiments, the target region information may be a display image of the display medical device, receiving user input to the display image, and generating in response to the input. The user can set the target area information corresponding to the target area concerned by the user, so that the image data required by the user can be acquired later, and the data transmission quantity is reduced.
That is, the target area information is preset, specifically, a display image of the medical device may be displayed, and input of a user for the display image is accepted, that is, a target area corresponding to display data in the display image is established, for example, the display image of the electrocardiograph monitor includes display data such as heart rate, blood pressure, blood oxygen, etc., and a target area corresponding to the display data such as heart rate, blood pressure, blood oxygen, etc. may be established; target areas corresponding to part of the data, such as heart rate and blood pressure display data, can be established according to actual needs.

Taking the example that the method is applied to the data transmission device 120, the display device may be a display module of the data transmission device 120; or a separate display connected to the input device; or a display with input functions such as touch, keys, etc., e.g., a cell phone, tablet, notebook, etc. In the case of displaying a display image of a medical device using a display other than the data transmission device 120, it is necessary to first transmit the display image to the display, for example, through an interactive interface of the data transmission device 120. The subsequent target area information generating step is performed by the display, and the data transmission device 120 may receive and store the target area information generated by the display.
And S230, sending the image data of the target area to the hospital equipment.
In some embodiments, network quality parameters may be acquired first. The network quality parameter comprises at least one of network signal strength, network bandwidth, network delay and packet loss rate. And then, according to the network quality parameters, determining a data transmission mode corresponding to the network quality parameters. And then, according to the data transmission mode, transmitting the image data of the target area to the hospital equipment. Therefore, a proper transmission mode can be flexibly selected according to the network quality, and the transmission effect is improved.
For example, the network quality level may be determined according to the network quality parameter, a data transmission mode corresponding to the network quality level may be selected as the target transmission mode, and the image data of the target area may be transmitted to the hospital device in the target transmission mode.
For example, the network quality level includes A, B, C three levels, which respectively represent excellent network, normal network, and poor network. When the network quality grade is A, image data of a target area are sent to hospital equipment in a mode 1; when the network quality grade is B, sending image data of a target area to hospital equipment in a mode 2; at a network quality level of C, image data of the target area is transmitted to the hospital equipment in manner 3.
Among them, mode 1 may include: and converting the image data of the target area into message data, and sending the message data and the image data of the target area to hospital equipment.
Mode 2 may include: converting the image data of the target area into message data, performing image blocking processing on the image data of the target area, reducing the data quantity, and sending the message data and the processed image data to hospital equipment. The image blocking process can keep the higher definition of the critical part and reduce the definition of the non-critical part.
Mode 3 may include: and converting the image data of the target area into message data, and sending the message data to the hospital equipment.
In other embodiments, network quality parameters may be acquired first. And under the condition that the network quality parameter is smaller than or equal to a preset parameter threshold value, switching the network to a target network, and sending the image data of the target area to the hospital equipment through the target network. The target network may be a network with optimal network quality. Therefore, the image data can be sent by flexibly selecting a proper network according to the network quality, and the sending effect is improved.
In the embodiment of the application, the display image of the medical equipment is acquired, the target area in the display image is identified according to the target area information corresponding to the medical equipment, the image data of the target area, namely the image data concerned by the user, is obtained, and further the image data of the target area is sent to the hospital equipment, so that the acquisition and transmission of useless data are avoided, the data transmission efficiency is improved, and the emergency efficiency is improved.
In some embodiments, prior to S220, the method may further comprise: the device identification of the medical device is obtained, the target area information corresponding to the medical device is determined according to the device identification, and the required target area information can be accurately determined. Referring to the example in S210, in the case where the medical device has an image output interface, the device identification of the medical device may be acquired through the image output interface; in the case where the medical device does not have an image output interface, a device identifier such as a two-dimensional code or a barcode may be set in advance on the outside of the frame line, and acquired by recognizing a captured image captured by the capturing device.
As one example, target area information matching the device identification may be looked up based on the device identification. Taking the application of the method to the data transmission device 120 as an example, the storage module of the data transmission device 120 stores the target area information by taking the device identifier as an index in advance. Accordingly, the target area information corresponding to the device identification can be searched in the storage module of the data transmission device 120. And then taking the target area information matched with the equipment identification as target area information corresponding to the medical equipment.
Optionally, the target area information may further include a target area identifier, a data type of display data corresponding to the target area, a data valid range, and a data alarm threshold. The target area position, such as target area coordinates and target area size, in the target area information corresponding to the device identifier may be mapped into the display image, display data in the target area is identified, and whether the display data is valid is determined according to the data valid range, the data type and the data alarm threshold in the target area information. If the display data is valid, the target area information matched with the equipment identifier is used as target area information corresponding to the medical equipment, and it can be understood that if the target area information matched with the equipment identifier is a plurality of pieces of target area information, the display data corresponding to each piece of target area information is valid; if not, as shown in the generation example of the target area information in S220, new target area information is generated, so that accuracy of the target area information corresponding to the medical device can be improved.
In addition, the target area information may also include a data refresh rate of the display data. It can be appreciated that a lower frequency refresh rate may be specified for display data with a slower update rate for identifying the target region at a slower frequency to obtain image data of the target region, thereby saving computational resources.
Fig. 3 illustrates a specific structure of the data transmission device 120 of fig. 1, and as shown in fig. 3, the data transmission device 120 may include an image data identification module, an image data transmission module, a target area information generation module, and a target area information storage module.

Among these, the BRTP protocol is not only a transmission protocol based on the user datagram protocol (User Datagram Protocol, UDP), but also a peer-to-peer communication from terminal to terminal or a one-way push communication protocol from terminal to server. The capability of using a plurality of network links is supported to transmit simultaneously, interconnection and intercommunication between cross-platform and cross-terminal are supported, and the BRTP protocol sets two mechanisms of forward error correction (Forward Error Correction, FEC) and automatic retransmission request (Automatic Repeat Request, ARQ) to solve the problem of network packet loss. In the data transmission process, the BRTP protocol monitors the transmission quality in real time, and dynamically adjusts coding, transmission and error correction modes when the network packet loss is serious, so that the data transmission is realized as much as possible. For example, the network of the data transmission unit may be opened to an external device, providing wired or wireless network access to the external device.
The following description will take the application of the data transmission method provided in the embodiment of the present application to the data transmission device 120 shown in fig. 3 as an example, and the data transmission method provided in the embodiment of the present application may include the following steps:
step 1, the target area information generating unit may display a display image of the medical device, receive an input of the display image by a user, and generate the target area information in response to the input.
And 2, the storage unit can store the generated target area information. Alternatively, the data in the target area information may be distributed to at least one database storage. For example, the first database stores the target area location, the target area size, and the target area identification with the device identification as an index. The first database stores the effective range of data, the data type, the data alarm threshold value and the data refresh rate by taking the device identifier as an index.
And 3, under the condition that the medical equipment is provided with an image output interface, the first image input unit, namely the special image input interface, can be connected with the image output interface of the medical equipment through a video signal connecting wire to acquire the display image of the medical equipment and the equipment identification of the medical equipment. In the case that the medical device does not have the image output interface, a border line of a specific color may be set in advance at the boundary of the display area of the medical device, and a device identifier may be set outside the border line, and the display area may be photographed by using the photographing device. The second image input unit, namely the universal image input interface, can be connected with the image output interface of the shooting device through the video signal connecting wire to acquire shooting images. The image pre-acquisition unit performs trapezoidal correction on the photographed image, identifies the device identifier in the photographed image after trapezoidal correction, and compares the identified device identifier with the device identifier stored in the storage unit in advance. If the comparison is successful, the identified equipment identifier is determined to be the equipment identifier of the medical equipment, and the image in the frame line is identified at the side edge of the equipment identifier, namely the image in the frame line is separated and used as a display image.
And 4, the information matching unit can map the target area position and the target area size in the target area information corresponding to the equipment identifier stored in the acquired storage unit into a display image, identify the display data in the target area, and judge whether the display data is effective or not according to the data effective range, the data type and the data alarm threshold value in the target area information.
