Description

Technical Field

[0001] The present invention relates to the technical field of infusion extravasation management, and in particular to a method and system for managing drug extravasation of an indwelling needle based on data processing. Background Art

[0002] An indwelling needle is a medical device, mainly used for treatments such as infusion, blood transfusion, blood collection, and blood pressure monitoring. It is mainly composed of a stainless steel puncture guide needle core and a soft catheter. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter has completely entered the blood vessel, the needle core is withdrawn, leaving only the soft catheter in the blood vessel for infusion therapy. Indwelling needles can be divided into open and closed types. The open type is divided into ordinary type and safety type (anti-needlestick type), and the closed type is divided into ordinary type and safety type (anti-needlestick type). In addition, according to different parts of use, indwelling needles can also be divided into venous indwelling needles, arteriovenous indwelling needles, arterial indwelling needles, etc.

[0003] The Chinese invention patent with publication number CN113140283A discloses a system and method for recommending drug leakage treatment for indwelling needles based on comprehensive group data analysis. The system includes a group data analysis database, an indwelling needle patient data entry subsystem, a data comparison subsystem, a data reminder subsystem, and a real-time measure recommendation subsystem.

[0004] However, in the prior art, when medical staff use an indwelling needle on a patient, they cannot promptly detect drug leakage from the needle, and are required to judge the usage time of the patient's indwelling needle based on their own experience, thereby increasing the risk of drug leakage from the needle or causing unnecessary replacement of the needle. Summary of the invention

[0005] The purpose of the present invention is to provide a method and system for managing drug leakage of an indwelling needle based on data processing, which can determine the maximum safe use time of the indwelling needle according to the patient's own conditions and reduce the risk of drug leakage.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A method and system for managing drug leakage of an indwelling needle based on data processing, comprising the following steps:

[0008] Step 1: Test the physical condition of the target patient to determine whether the patient has a permeable constitution;

[0009] Step 2: Real-time collection of usage data of the indwelling needle to obtain the exudation characterization value, thereby determining whether the drug is likely to exudate;

[0010] Preset the exudation threshold SY, and compare and analyze the exudation characterization value SC with the exudation threshold SY;

[0011] If the exudation characterization value SC ≤ the exudation threshold SY, it is determined that the drug has no possibility of exudation;

[0012] If the exudation characterization value SC>exudation threshold SY, it is determined that the drug has the possibility of exudation;

[0013] Step 3: Based on the historical extravasation characterization values ​​of indwelling needles with different usage durations, analyze the longest usage duration with the lowest risk of drug extravasation of the indwelling needle under the same status characterization values ​​of the patients.

[0106] Embodiment 2:

[0107] Based on Example 1, please refer to Figure 4 As shown, an indwelling needle drug leakage management system based on data processing according to an embodiment of the present invention includes:

[0108] The data acquisition module is used to detect the physical condition of the target patient and determine whether the patient has a permeable constitution;

[0109] The data acquisition module is used to collect the usage data of the indwelling needle in real time and obtain the exudation characterization value, so as to determine whether the drug has the possibility of exudation;

[0110] The data analysis module is used to analyze the longest use time with the lowest risk of drug leakage of the indwelling needle under the same status characterization value of the patient based on the historical leakage characterization values ​​of the indwelling needles with different use time;

[0111] The data acquisition module includes: a data acquisition unit for obtaining the patient's test data; a data processing unit for calculating the state characterization value according to the obtained test data, and determining whether the patient has an easily permeable constitution;

[0112] The data acquisition module includes: a data acquisition unit for collecting the usage data of the patient when using the indwelling needle in real time; a data analysis unit for calculating the exudation characterization value based on the obtained usage data, and judging whether the drug has the possibility of exudation;

[0113] It also includes: an alarm module for receiving a patient status warning signal and generating a patient status pre-warning; receiving a drug leakage warning signal and generating a drug leakage pre-warning.

[0114] The size of the above threshold is set for the convenience of comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; for example: the process of obtaining the state threshold is: in the actual process, there are many groups of skin relaxation characterization values, vascular elasticity characterization values ​​and blood circulation characterization values. Many groups of skin relaxation characterization values, vascular elasticity characterization values ​​and blood circulation characterization values ​​are processed to obtain the state characterization values ​​of the corresponding groups. The staff evaluates whether the patient has an easy-to-permeate constitution based on so many groups of state characterization values, thereby obtaining a corresponding relationship between a state characterization value and whether the patient has an easy-to-permeate constitution, and then derives and divides the threshold of the state characterization value according to whether the patient has an easy-to-permeate constitution, thereby obtaining the state threshold, and comparing the obtained state characterization value with the state threshold, that is, completing the identification of whether the patient corresponding to the state characterization value has an easy-to-permeate constitution; the acquisition methods of the above other thresholds are the same as the acquisition method of the state threshold;

[0115] The above formulas are obtained by collecting a large amount of data and performing software simulation to select a formula close to the actual value. The factors in the formula are set by technicians in this field according to actual conditions; for example: formula ZT = a1 × (1-PF) 2 +a2×(1-XG) 2 +a3×(1-XY) 2 ; A technician in this field collects multiple groups of test data and sets a corresponding state characterization value for each group of test data; Substitute the set state characterization value and the collected test data into the formula, any three formulas constitute a three-variable linear equation system, screen the calculated factors and take the average, and obtain the values ​​of a1, a2, and a3, which are 2.37, 2.25, and 1.63, respectively;

[0116] The size of the factor is to quantify each parameter to obtain a specific value, which is convenient for subsequent comparison. The size of the factor depends on the amount of test data and the initial setting of the corresponding state characterization value for each set of test data by technicians in this field; as long as it does not affect the proportional relationship between the parameter and the quantified value, such as the state characterization value is proportional to the value of the skin relaxation characterization value;

[0117] Formula: SC=b1×YL+b2×WD+b3×LL, the values ​​of b1, b2, and b3 are 2.96, 2.45, and 3.21, respectively, and the method of obtaining them is the same as the factor obtaining method of the above formula.

[0118] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
