In this example, as shown in fig. 2, the document parser module includes a document structure unit, a document style unit, a care document unit, a document rendering unit, and a function module unit.

The document structure unit mainly standardizes the structure system of the electronic medical record document, the document structure is an internal carrier of the electronic medical record document, and various medical record documents are displayed. The method comprises the steps that an overall document structure of an electronic medical record is realized through an OOXML document standard object tree, the OOXML document standard object tree comprises a header, a footer and a main body object tree, all elements in the overall document are collectively called as nodes of the object tree, the nodes comprise a father node and a child node, the child node is collected in a collection mode, the child node points to the father node in a pointer mode, and therefore a complete set of document object tree structure is realized; nodes include paragraphs, forms, fields, input boxes, text, pictures, graphics, medical formulas, and the like.

The document object tree extends through all modules of the entire electronic medical record document. As almost all module operation objects, such as position calculation, cursor jump, element node addition, deletion and verification, etc., the width and height of each occupied node are calculated in an integral mode from father to son and from front to back through an object tree of a document structure, the node principle is sequentially arranged, the position information of each node is calculated and stored on the corresponding node object, and a complete document node position calculation algorithm is formed. The document data is extracted based on a document object tree, which is created based on the document data, and the document object tree complement each other.

Splitting algorithm: the target cell is split into the required rows and columns according to the split row-column parameters. There is a limitation in that the row of the target cell split must be an integer multiple of the row occupied or a row. An increase in the number of columns split triggers a corresponding increase in the set of table columns.

the rule renderer module is used as a guarantee system architecture of the electronic medical record editor, determines specific actions through events, configures corresponding conditions to determine specific ranges, and executes corresponding specified actions to ensure standardization, integrity and logic of data during writing of the document; the rule renderer module comprises a real-time quality control unit and an intelligent expansion assembly unit, wherein the real-time quality control unit is used for performing value range verification, input restriction, format verification, text error correction and automatic prompt on the document content according to the quality control rule predetermined by the rule renderer by adopting a mode of regular verification and built-in verification rules, and hiding, desensitizing and watermarking are displayed according to conditions; the intelligent expansion assembly unit is used for adopting an interface setting mode, and is configured in a linkage mode between a plurality of elements and data group structures in the same document so as to improve the expandability and the intelligent ability of the editor, and comprises: the hierarchical authority control block is used for controlling the hierarchical authority of the medical record document; the rule linkage configuration block is used for realizing intelligent display of different structural contents according to specified events and conditions; the segment configuration block is used for quickly constructing a template, and extracting characters, styles and elements of specified paragraphs in the medical record document by adopting a document selection algorithm mode to form a complete segment structure; the header fragment block is used for quickly constructing a header and modifying the header, adopts the concept of a mother and child template, independently constructs the header and integrates the header in a quoted mode; the intelligent expansion assembly unit is internally provided with an external integration unit which is used for directly butting a quality control system, performing back-end quality control by using a rule engine and butting an integrated intelligent auxiliary diagnosis system;

the multi-mode converter module is used for realizing multi-terminal and multi-writing modes of the electronic medical record editor as middleware, wherein multi-terminal means that the multi-terminal renders the document effect of the corresponding terminal through one set of data; rendering of the mobile terminal is realized through browser styles, and input-capable and storable mobile terminal functions are provided; the method achieves the inputtable function of the mobile terminal by being compatible with css style, and can save the function; according to the internally defined paragraph object, style object, document object, domain object and control object, calculating the positions of different objects so as to draw the data content of the mobile terminal through canvas; the multi-writing mode is to calculate different document node positions according to different character directions, so as to achieve the effect of rendering different character directions, and comprises a left-to-right and top-to-bottom writing mode, a top-to-bottom and left-to-right writing mode and a top-to-bottom and right-to-left writing mode; for a left-to-right and top-to-bottom writing mode, calculating a width with the width of the content area as a limit and calculating a height with the height of the content area as a limit; for the top-down, left-to-right writing mode and the top-down, right-to-left writing mode, the width is calculated with the height of the content area as a boundary, and the height is calculated with the width of the content area as a boundary; for the top-down and right-to-left writing modes, the transverse position needs to be subjected to a difference operation with the width of the content area to obtain an actual position during rendering;

the integrated view module is used for forming closed-loop data display by summarizing various data of patients in the electronic medical record in multiple dimensions and multiple layers by taking time as an axis, adopting a view technology system of canvas and a two-dimensional drawing engine ZRender, generating an integral page in a canvas mode, completing rendering of the whole page according to a coordinate algorithm and a document rendering algorithm, adopting an object-oriented MVC mode in graphic rendering, and enabling a view layer to be responsible for rendering and a control layer to be responsible for user input interaction and enabling a data layer to be responsible for arranging and storing a data model.
