Problems solved by technology

This method focuses on providing a method of mixing Chinese and English, and does not carefully consider the compression efficiency, because when adding a flag, it is necessary to consider the impact of the flag on the decoding of the halfman code. In order to avoid the halfman code after adding the flag The impact of decoding must constrain the encoding of signs and halfman, which seriously affects the efficiency of compression

Embodiment 1

[0035] Embodiment 1: as figure 1 As shown, a data compression method for electronic medical records includes the following steps:

[0036] Step 1, build a 20×20×20 three-dimensional array arry_3rd, the three dimensions of the three-dimensional array correspond to the area, segment, and bit respectively, where N1 is the maximum number of areas, N2 is the maximum number of segments, and N3 is the maximum number of bits .

[0037] Step 2: fill in characters in sequence, and the characters include Chinese characters, ASCII characters, and control characters.

[0038] Specifically, characters in the GB2312 encoding table can be used for Chinese characters, and other necessary characters such as ASCII characters and control characters are filled in the remaining space.

[0039] Step 3, use ASCII characters to identify the area, segment, and bit of the three-dimensional array arry_3rd.

[0040] Step 4, create a character identification table dic_character, which stores the one-to-...

Embodiment 2

[0054] Embodiment 2: In this embodiment, due to space limitations, and also because the present invention is aimed at compressing Chinese characters, we use the most common case in electronic medical records, and take 20 characters as an example to illustrate the compression process:

[0055] The patient presented with left lower chest discomfort for no apparent reason four days earlier

[0056] Step 1 is based on the constructed character identification table dic_character and the ASCII identifiers used by the character identification table dic_character, as shown in Table 2. The generation steps of the character identification table dic_character are as described above and will not be described here.

[0057]

[0058]

[0059] Table 2

[0060] Take the area identifier, segment identifier, and bit identifier for the characters in the above case in turn, and generate an ASCII character string. In each group of three characters, the first character is the area identifier,...

Embodiment 3

[0073] Embodiment 3: Due to space limitations, and also because the present invention is aimed at Chinese character compression, we use the most common case in electronic medical records, and take 200 characters as an example to illustrate the process of compression:

[0074] The patient had discomfort in the lower left chest for no obvious reason four days ago, without cough or sputum, and without fear of cold and fever. No attention was paid and no treatment was given. Six hours ago, after eating cold dishes, the left lower chest discomfort occurred again, without diarrhea, nausea, and vomiting. No attention was paid, and the symptoms were not relieved after self-administration of Xingjun powder. The local health center gave oral medicine and intramuscular injection of liquid (the details are not detailed). The discomfort in the left chest did not improve significantly, and there was chills and cold limbs. Myocardial zymogram showed high levels of aspartate aminotransferas...

Abstract

The invention relates to a data compression and decompression method for electronic medical records. According to the method, each character, expressed by an area code and a bit code, in a GB2312 Chinese coded character set is converted to be expressed by an area number, a segment number and a bit number, then the area number, the segment number and the bit number are identified by ASCII characters, no requirement and consumption is set for a corresponding relation between the ASCII characters and the numbers, so that a single Chinese character can be expressed by the three ASCII characters, a Chinese character string can also be converted into an ASCII character string, and compression and decompression are achieved by making statistics on the ASCII characters and coding the same. The method has the characteristics that compression is performed on the Chinese characters, compression efficiency is not influenced by a repetition rate of the Chinese characters, and meanwhile computation pressure of a server can be relieved; the method is convenient to use and high in reliability.

Description

technical field [0001] The invention relates to the field of medical record data management, in particular to a data compression and decompression method for electronic medical records. Background technique [0002] With the continuous maturity and expansion of hospital informatization, the growth of electronic medical record information has reached an unprecedented scale. The large-scale growth of electronic medical record information and the continuous expansion of personal electronic medical record information have not only encountered problems in data storage and retrieval. , and encountered various transmission problems in remote diagnosis and treatment, cross-regional information sharing and other applications. [0003] Compression is one of the effective means to improve the efficiency of information in the process of storage and transmission. People use various compression methods, such as the most representative halfman algorithm in the traditional compression metho...
