Description

Technical Field

[0001] The present invention relates to the technical field of medical safety, and particularly to a zero-character full-symbol medication guidance system based on foolproof design. Background Art

[0002] The accurate transmission of medication guidance information is the core link to ensure patient medication safety. In current clinical and home medication scenarios, medical orders, prescriptions, drug instructions, and medication guidance sheets generally use text forms such as Chinese characters, numbers, and English abbreviations to transmit medication information. However, text carriers have an inherent risk of information distortion: handwritten prescriptions are often difficult to identify due to scribbled or blurred handwriting, and printed text is prone to confusion due to similar fonts (such as "1" and "7", "3" and "8"), similar glyphs (such as "日" and "目", "二" and "三"), and English abbreviations (such as "bid" and "tid") are more likely to cause frequent misreading due to memory deviation or misunderstanding. Statistics from the World Health Organization show that more than 2.5 million people die annually due to medication errors globally, and nearly half of them are directly related to text recognition errors. A report by the US National Academy of Medicine pointed out that about 7,000 people die annually due to blurred prescription handwriting. Data from the National Clinical Medication Safety Monitoring Network shows that dosing frequency errors account for 11.35% of medication errors, and the confusion between "twice a day" and "three times a day" accounts for more than 70%. The above problems indicate that the traditional text-dependent medication guidance system has fundamental defects at the information coding level and cannot fundamentally prevent medication misreading caused by text blurring, glyph ambiguity, and cultural level differences.

[0003] Furthermore, the existing text-based medication guidance system has coverage blind spots for specific high-risk groups. Illiterate and semi-literate people cannot recognize Chinese character instructions at all, elderly people with low vision have difficulty distinguishing small text and similar glyphs due to vision decline, people with low cultural levels have limited understanding ability for complex text instructions, and cognitively impaired people have a significantly reduced information reading efficiency in emergency situations. More than 68% of the above groups are the main body of medication accidents, but they have long been in the service blind spot of traditional medication guidance. Although some medication guidance in the prior art uses simple graphics for assistance, there is no unified symbol standard system, and graphics and text are mixed, and it has not completely gotten rid of text dependence; the meanings of graphics are not unified between different drugs and different institutions, and patients need to repeatedly learn and remember, and cannot form instinctive recognition; at the same time, the existing solutions do not cover the entire medication process, mostly only graphically prompt the dosing frequency or dose, lacking a systematic design for key links such as medication time conditions, contraindication warnings, adverse reaction handling, and missed dose handling. Therefore, there is an urgent need for a medication guidance system that completely gets rid of text, has a unified standard, covers the entire process, and is applicable to all people to eliminate medication errors caused by text recognition obstacles from the root. Summary of the Invention

[0004] In order to solve the problems of the prior art, the present invention provides a zero-text, all-symbol medication guidance system based on mistake-proof design.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: Firstly, a zero-text, all-symbol medication guidance system based on mistake-proof design, comprising: The medication frequency symbol module is configured to use a textless graphic to indicate the number of daily medications. The medication time symbol module is configured to distinguish medication time periods using graphics. The dosage symbol module is configured to use geometric shapes to identify the dosage of a single dose. The medication route symbol module is configured to identify the medication route using human body parts or life-related graphics. The contraindication warning symbol module is configured to use prohibited graphics to indicate drug contraindications. The adverse reaction handling symbol module is configured to use medical-related graphics to indicate adverse reaction handling methods; and The missed service handling symbol module is configured to use graphics to indicate the processing guidelines after a missed service. All symbols are purely graphic symbols without text or abbreviations, and they are visually distinguished using uniform graphics, colors, and shapes to form a foolproof medication information transmission system that can be intuitively recognized without the need for textual learning.

[0006] In one specific embodiment of the first aspect, the medication frequency symbol module includes: A single solid dot graphic representing a single occurrence once a day; The combination of sun and moon symbols represents two daily occurrences; and It represents a combination of the sun, noon, and moon symbols, displayed three times a day.

[0007] In one specific embodiment of the first aspect, the medication time symbol module includes: A graphic combination of an image of rice to be taken before meals and a prohibition symbol; A graphic combination of a rice image representing food to be consumed after meals and a confirmation mark; An image of an empty bowl indicating that the medicine should be taken on an empty stomach; and A graphic combining a moon symbol and a sleep symbol, representing medication taken before bedtime.

[0008] In one specific embodiment of the first aspect, the dosage symbol module includes: A hollow circular graphic representing a dosage tablet; Two side-by-side hollow circles representing two dosages; A semi-circular graphic representing half a tablet quantity; and A simplified symbolic representation of a single-dose bag.

[0009] In one specific embodiment of the first aspect, the route of administration symbol module includes: A graphic symbol indicating oral administration; A graphic symbol representing a hand for external use; The graphic symbol for confirming eye drops; and A graphic symbol indicating the use of a toilet for anal use.

[0010] In one specific implementation of the first aspect, the taboo warning symbol module includes: A graphic combining an image of a wine bottle indicating that drinking is prohibited with a red prohibition symbol; A graphic combining an image of a pregnant woman and a red prohibition symbol, indicating that the content is prohibited for pregnant women; and A graphic combining a child image that indicates children should not touch it with a red prohibition symbol.

[0011] In one specific embodiment of the first aspect, the adverse reaction handling symbol module includes: A combination of a cross symbol indicating immediate cessation of medication and a warning triangle; An image of an ambulance indicating immediate medical attention; and A graphic combination of medical device images and warning symbols indicating an allergic reaction alarm.

[0012] In one specific embodiment of the first aspect, the missed service processing symbol module includes: A combination of an alarm clock graphic and a forward arrow indicating immediate replenishment; and The combination of an alarm clock graphic and a cross symbol indicates skipping this time and taking the alarm normally next time.

[0013] In one specific implementation of the first aspect, the system is configured to combine the symbols of each module in sequence to form a complete medication information guidance chain, wherein the sequence is as follows: medication frequency, medication time, medication dosage, route of administration, contraindications warning, adverse reaction handling, and missed dose handling.

[0014] In one specific embodiment of the first aspect, the system is configured to be printed or displayed on a medicine box, medication instructions, or prescription carrier.

[0015] The beneficial effects of this invention are as follows: 1. By constructing a zero-text, all-symbol graphic system, the reliance on textual symbols in the transmission of medication information is fundamentally severed. Specifically, this system maps seven core information dimensions—dosage frequency, dosing time, dosage, route of administration, contraindications and warnings, adverse reaction handling, and missed dose handling—to independent and unambiguous pure graphic symbol modules. Each module adopts unified visual coding rules for graphics, colors, and shapes. Color coding follows the error-proof logic of red prohibition, yellow warning, and blue instruction in the GB 2894 standard, while shape coding follows the differentiation principle of circular prohibition, triangular warning, and square instruction. This completely eliminates the risk of misreading information caused by inherent defects in text, such as blurred handwriting, similar fonts, confused English abbreviations, and ambiguous fonts. Based on this, the system combines the symbols of each module into a complete information chain in a fixed sequence of "frequency → time → dosage → route → contraindications → adverse reactions → missed doses". This allows patients to obtain all medication instructions in sequence without any text decoding or semantic understanding, simply by instinctively recognizing the graphic symbols. This achieves a zero-learning-cost anti-misreading design from the source of information encoding.

[0016] 2. This system migrates the mature national standard system for drawing-first and error-proofing from the construction industry to the medical and pharmaceutical scenario, forming a systematic technical solution covering the entire population, all dosage forms, and all media. In terms of population coverage, purely graphic symbols completely eliminate the need for text recognition, enabling accurate identification and execution for people in traditional text-based guidance blind spots such as the illiterate, elderly with low vision, those with low literacy levels, and those with cognitive impairments. Regarding dosage form compatibility, the dosage symbol module establishes universal adaptation rules—one graphic per unit, dedicated graphics for fractional doses, and dosage form mapping—through variations in the number and shape of geometric shapes, seamlessly covering all clinical dosage forms including tablets, capsules, granules, liquids, injections, external applications, and intracavitary applications. In terms of media compatibility, the system replaces color-based error-proofing with line type differentiation (solid / double / dashed lines), ensuring information integrity on black-and-white printing and various display media. This technical solution requires no hardware modification and can be implemented simply by printing standardized symbols. It achieves unified information throughout the entire process from prescription issuance and medicine packaging to medication guidance sheets, forming a standardized medication safety barrier that can be reused across regions, institutions, and populations. This fundamentally solves the security blind spot problem of text-based medication guidance systems. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 3 The image shows a zero-text, all-symbol medication guidance system based on a mistake-proof design.

[0022] I. System Overall Architecture This invention provides a zero-text, all-symbol medication guidance system based on mistake-proof design. The system includes seven core symbol modules: medication frequency symbol module, medication time symbol module, medication dosage symbol module, route of administration symbol module, contraindication warning symbol module, adverse reaction handling symbol module, and missed dose handling symbol module. All symbols are purely graphic symbols without text or abbreviations, and use uniform graphics, colors, and shapes for visual differentiation, collectively forming a mistake-proof medication information transmission system that can be intuitively recognized without the need for textual learning.

[0023] The system is configured to combine the symbols of the seven modules mentioned above in a predetermined order and print or display them on medicine boxes, medication instructions, or prescription carriers. By recognizing the graphics, colors, and shapes, patients can accurately follow the complete information chain of "medication frequency → medication time → medication dosage → route of administration → contraindications warnings → adverse reaction management → missed dose management," achieving safe medication guidance throughout the entire process with zero text and zero misreading.

[0024] II. Specific Implementation Methods of Each Module (a) Medication frequency symbol module This module is used to identify the daily frequency of medication use, and uses a combination of graphics to intuitively express the frequency information. The specific implementation method is as follows: Once a day: Represented by a single solid dot. This graphic is simple and clear, symbolizing the singularity of "once," consistent with the dot-like markings used in daily life, and can be understood without any learning.

[0025] Twice daily: Represented by a combination of sun and moon images. The sun symbolizes morning, and the moon symbolizes evening. The combination visually conveys the frequency of medication, "once in the morning and once in the evening," which aligns with human understanding of the natural cycle of day and night.

[0026] Three times daily: Represented by a combination of sun, noon, and moon images. The sun represents morning, noon represents midday, and the moon represents evening; the combination clearly expresses the frequency of medication: once each in the morning, noon, and evening.

[0027] All the above graphics are printed in black or dark colors to ensure clear contrast and easy identification by people with low vision.

[0028] (ii) Medication Time Symbol Module This module is used to distinguish medication time periods, using a combination of lifelike graphics and confirm / prohibit markers to express time conditions. The specific implementation method is as follows: Take before meals: This is indicated by a combination of a rice pattern and a prohibition symbol. The rice represents "eating," and the prohibition symbol superimposed on it indicates that the medication should be taken "before eating," i.e., on an empty stomach.

[0029] Take after meals: This is indicated by a combination of a rice pattern and a confirmation mark. The confirmation mark is superimposed on the rice pattern to indicate "take after meals".

[0030] Take on an empty stomach: Represented by an empty bowl. The empty bowl symbolizes a stomach without food, visually conveying the requirement of fasting "at least one hour between meals or before meals".

[0031] Take before bedtime: The medication is represented by a combination of a moon and a sleep symbol. Both the moon and the sleep symbol are common symbols of nighttime rest, and the combination clearly indicates the time of day for taking the medication "before bedtime".

[0032] (III) Dosage Symbol Module This module is used to identify a single medication dosage, expressing dosage information through the quantity and shape changes of geometric shapes. The specific implementation method is as follows: One tablet (or one pill): Represented by a hollow circle. The hollow circle symbolizes a complete solid dosage form, with one circle corresponding to one unit dose.

[0033] 2 tablets: Represented by two side-by-side hollow circles. The two circles arranged side-by-side clearly express the dosage requirement of "two tablets".

[0034] Half tablet: Represented by a combination of semicircles. The semicircle symbolizes dividing a complete circle into half, visually expressing the dosage requirement of "half a tablet".

[0035] 1 bag: Represented by a simplified bag-shaped symbol. This graphic mimics the common packaging form of pharmaceutical granules and powders, visually conveying the dosage information of "one bag".

[0036] (iv) Drug administration route symbol module This module is used to identify the route of administration, using a combination of human body parts or life-related graphics and confirmation markers to express the method of medication. The specific implementation method is as follows: Oral administration: Represented by a mouth-shaped identification symbol. The mouth symbol clearly points to the oral cavity, and the identification mark indicates "entry through this point," together clearly expressing the "oral" route.

[0037] External use: Represented by a hand-shaped confirmation symbol. The hand symbol symbolizes external application operations such as smearing or applying, and the confirmation mark indicates "applied to the body surface". Together, they clearly express the "external use" route.

[0038] Eye drops: Represented by an eye identification symbol. The eye symbol clearly points to the eye, and the identification mark indicates "instilled into the eye." Together, they clearly express the route of administration for "eye drops."

[0039] Rectal use: Represented by a toilet symbol. The toilet symbol is a common symbol for rectal excretion, and the symbol indicates "administration via the anus." Combined, they clearly express the "rectal use" route and are suitable for suppositories, enemas, and other dosage forms.

[0040] (v) Prohibition and Warning Symbols Module This module is used to identify medication contraindications. It uses a combination of prohibition-related graphics and related objects to express absolute prohibitions. The specific implementation method is as follows: "No Alcohol Consumption": This is indicated by a combination of a bottle image and a red prohibition symbol. The red prohibition symbol is superimposed on the bottle, conforming to the "red prohibition" design principle in the GB 2894 standard for the construction industry, and directly conveying the warning message that "alcohol consumption is prohibited while taking medication."

[0041] Not for use by pregnant women: This designation uses a combination of an image of a pregnant woman and a red prohibition symbol. The image of the pregnant woman clearly indicates that the product is for pregnant women, while the red prohibition symbol superimposed on top clearly conveys the prohibition against use by pregnant women.

[0042] Keep out of reach of children: This is indicated by a combination of a child's image and a red prohibition symbol. The child image clearly targets minors, while the red prohibition symbol superimposed on top conveys the safety warning: "Keep medicine out of reach of children."

[0043] (vi) Adverse reaction handling symbol module This module is used to indicate how to handle adverse reactions. It uses a combination of medical-related graphics and warning symbols to express emergency guidance. The specific implementation method is as follows: Immediate discontinue use: This is represented by a combination of a cross and a warning triangle. The cross symbolizes "stop," and the warning triangle symbolizes "dangerous situation." Together, they convey the emergency instruction to "stop medication immediately if adverse reactions occur."

[0044] Seek immediate medical attention: This is represented by a combination of an ambulance graphic and a warning triangle graphic. The ambulance is a general symbol for emergency medical care, and the warning triangle superimposed on top of it conveys the emergency instruction to "go to a medical facility immediately after experiencing adverse reactions."

[0045] Allergy Reaction Alarm: Represented by a combination of medical device graphics and warning symbols. The medical device symbolizes professional medical intervention, while the warning symbols emphasize urgency. Together, they convey the clear instruction: "Seek immediate medical attention if allergy symptoms such as rash or difficulty breathing occur."

[0046] (vii) Missed Service Processing Symbol Module This module provides guidance on handling missed medication doses, using a combination of time-related graphics and directional symbols to express operational suggestions. The specific implementation method is as follows: Immediate Replenishment: Represented by a combination of an alarm clock graphic and a forward arrow. The alarm clock symbolizes a "time point," and the forward arrow indicates "immediate execution." The combination conveys the instruction to "make up for missed doses immediately."

[0047] Skip this dose, take the normal dose next time: This is represented by a combination of an alarm clock icon and a cross. The combination of the alarm clock and the cross indicates "skip the missed dose," and combined with the subsequent normal dose symbol, it fully conveys the instruction "skip this dose and take the normal dose next time."

[0048] III. Information Combination and Presentation Methods The system configuration of this invention combines the symbols of the above seven modules in a fixed order to form a complete medication information guidance chain. The specific combination order is as follows: The symbols for medication frequency, medication time, medication dosage, route of administration, contraindications / warnings, adverse reaction management, and missed dose management are listed. In practical applications, these symbols are printed horizontally or vertically on medicine box labels, medication instructions, or prescriptions. Appropriate spacing is used between each symbol module to ensure visual clarity and prevent confusion. For medicines containing multiple contraindications or various adverse reaction management methods, multiple symbol graphics can be displayed side-by-side within the corresponding module.

[0049] To further enhance the error-proofing effect, this system also adopts the following visual design rules: Color-coded error prevention: Warning symbols (contraindication warnings, adverse reaction handling) are uniformly marked with red borders or red backgrounds; instruction symbols (dosage frequency, dosing time, dosage, route of administration) are uniformly marked with black or dark colors; handling guidance symbols (missed dose handling) are uniformly marked with blue or green, forming a color coding system that conforms to the GB 2894 standard.

[0050] Shape-based error prevention: Prohibition symbols should uniformly adopt a circle with a slash; warning symbols should uniformly adopt a triangle with an exclamation mark; instruction symbols should uniformly adopt a square or circle shape to avoid cognitive ambiguity caused by shape confusion.

[0051] Combined error prevention: All medication information for the same drug is printed in a uniform format, size, and font style, ensuring that patients can quickly identify the meaning of symbols in different drugs and scenarios without having to learn them repeatedly.

[0052] IV. Examples The technical solution of the present invention will be verified by a specific embodiment below.

[0053] Example: Dosage guidance for a certain brand of amoxicillin granules A pharmaceutical company produces amoxicillin granules (specification: 0.125g / sachet). The drug information listed in its package insert is as follows: Adults: Take 2 sachets 3 times daily after meals. Children: Calculate the dosage according to weight, take 1 sachet 3 times daily after meals. Contraindications: Not for use in patients with penicillin allergy. Management of adverse reactions: If allergic reactions such as rash occur, discontinue use immediately and seek medical attention. Missed dose management: Take the missed dose immediately. According to the technical solution of the present invention, the medication guidance information of the drug is converted into the following combination of zero text and all symbols: Adult medication information package: Medication frequency symbol: (3 times daily) Medication timing symbol: (take after meals) Dosage symbol: (2 sachets) Route of administration symbol: (oral) Contraindication warning symbol: (Penicillin allergy is contraindicated; a syringe icon is used instead of the penicillin symbol) Adverse reaction management symbols: (Discontinue medication immediately, seek medical attention immediately) Missed dose processing symbol: (Take the missed dose immediately) Children's medication information compilation: Medication frequency symbol: (3 times daily) Medication timing symbol: (take after meals) Dosage symbol: (1 sachet) Route of administration symbol: (oral) Contraindication warning symbol: (Keep out of reach of children; also not for use by adults if you have a penicillin allergy). Adverse reaction management symbols: (Discontinue medication immediately, seek medical attention immediately) Missed dose processing symbol: (Take the missed dose immediately) The above-mentioned symbol combination is printed horizontally on the medication instruction label on the side of the medicine box, and also in an enlarged version on the medication instruction sheet included inside the medicine packaging. After obtaining the medicine, patients do not need to read any text; they can accurately obtain all medication information simply by recognizing the graphic symbols.

[0054] Verification results: To verify the system's ability to prevent misreading, 50 subjects were selected for a recognition test. The subject composition is as follows: Illiterate or semi-literate individuals: 15 people; Elderly individuals with low vision (over 60 years old, visual acuity ≤0.3): 15 people; People with low levels of education (primary school education or below): 10 people; Individuals with mild cognitive impairment: 5 people; Normal control group: 5 people; Test method: The subjects were shown the above combination of symbols and asked to verbally describe the medication information they understood, which was then compared with the information in the original drug instructions.

[0055] Test results: All 50 participants were able to accurately identify key medication information such as "3 times a day", "take after meals", and "oral administration"; 48 subjects were able to accurately identify the dosage difference between "2 bags" and "1 bag"; 47 participants were able to accurately identify emergency treatment guidelines such as "stop medication immediately" and "seek medical attention immediately"; 45 subjects were able to accurately identify the "take the missed dose immediately" instructions for handling missed doses; The overall recognition accuracy rate reached over 94%, far exceeding that of the control group (the average accuracy rate of the same subject reading the text version of the instruction manual was 63%).

[0056] The above embodiments demonstrate that the zero-text, all-symbol medication guidance system of the present invention can completely eliminate text dependence, achieve the goal of medication safety for all population groups, all scenarios, and zero misreading, and has significant error prevention effects and clinical application value.
