Description

Technical Field

[0001] The present invention relates to the technical field of drug identification, and particularly to an automatic pill dispenser with drug identification. Background Art

[0002] During the medical process, especially for patients suffering from multiple diseases who need to take multiple drugs simultaneously, manual pill dispensing is prone to errors, such as taking the wrong drug, inaccurate dosage, etc. These errors may lead to poor treatment effects for patients, and even adverse reactions, endangering lives. An automatic pill dispenser with drug identification can ensure the correct types and dosages of drugs taken by patients each time through precise identification technology and automated pill dispensing processes, improving the safety and effectiveness of medication. Therefore, it is particularly important to invent an automatic pill dispenser with drug identification.

[0003] An existing technology, such as a drug distribution and identification device disclosed in the invention patent application with the publication number CN217739972U, includes a distribution box with a partition plate inside. A bottom motor is connected to a threaded column, and a moving plate is connected to the threaded column through a threaded hole and can slide. A connecting column and a drug placement box are connected in sequence above it. Patients take drugs through the drug-taking port, and an electric push rod keeps the drug at the drug-taking port position. This device facilitates drug distribution and identification, avoiding the high energy consumption of medical staff and drug distribution errors caused by inattention.

[0004] The existing technology has the following defects, specifically: 1. In the existing technology, the pill dispensing method often relies on manual operation or simple counting devices. For drugs that need to be cut, it is difficult to ensure the cutting accuracy, resulting in inaccurate drug dosages for patients, difficult to meet the precise medication needs of patients, leading to poor treatment effects for patients, and even adverse reactions, endangering lives.

[0005] 2. In the existing technology, the pill dispensing equipment cannot automatically synchronize information with the hospital HIS system. Manual entry of prescriptions is prone to errors and low efficiency. At the same time, it lacks an abnormal alarm function and cannot detect and handle in a timely manner when tablets are stuck, the inventory is insufficient, or the dosage limit is exceeded, affecting the normal progress of the pill dispensing process. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic pill dispenser with drug identification, which solves the problems in the background art.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an automatic pill dispenser with drug identification, including: a prescription information acquisition module, which is used to acquire patient prescription information based on the patient's prescription, including drug name, drug dosage form, dosage, and administration time.

[0008] The drug identification module is used to identify the target drug from the built-in drug database of the device based on the patient's prescription information by using a high-resolution camera + AI image recognition algorithm.

[0009] The flexible sorting unit is used to sort the target drug from the built-in drug database of the device by using a silica gel suction cup or a micro manipulator based on the patient's prescription.

[0010] The dispensing and labeling module is used to package and label the target drug.

[0011] The intelligent control module uses an STM32 / Raspberry Pi as the main control chip, connects to the hospital HIS system, automatically synchronizes the generation of the medication plan, and also has an abnormal alarm function.

[0012] Preferably, the high-resolution camera + AI image recognition algorithm is used to identify the color, shape, indentation and packaging information of the drug, and also supports OCR character recognition for reading the drug name, dosage and expiration date information on the medicine board.

[0013] Preferably, the flexible sorting unit includes a counting module, a cutting module and a weighing module.

[0014] The counting module is used to extract the dosage of the drug in the patient's prescription and dynamically count the target drug by using an infrared sensor and a photoelectric counter.

[0015] The cutting module is used to judge whether the target drug needs to be cut based on the patient's prescription. If the target drug needs to be cut, the target drug is cut based on the dosage form of the target drug.

[0016] The weighing module is used to weigh the cut target drug to judge whether it meets the accuracy requirements.

[0017] Preferably, the method for judging whether the target drug needs to be cut is as follows: extract the dosage of the drug in the patient's prescription, extract the single-dose standard dosage of the target drug from the built-in drug database of the device, and compare them. If the dosage of the drug in the patient's prescription is less than the single-dose standard dosage of the target drug extracted from the built-in drug database of the device, it is determined that the target drug needs to be cut. If the dosage of the drug in the patient's prescription is greater than or equal to the single-dose standard dosage of the target drug extracted from the built-in drug database of the device, it is determined that the target drug does not need to be cut.

[0018] Preferably, the method for cutting the target drug based on the dosage form of the target drug is as follows: extract the dosage form of the target drug. If the dosage form of the target drug is tablet-shaped, use a laser cutting head to cut the target drug. If the dosage form of the target drug is capsule-shaped, use a pressure blade to cut the target drug.

[0019] Preferably, the dispensing and labeling module supports the patient to select the dispensing method, which is divided into per-dose dispensing and periodic dispensing. If the patient selects per-dose dispensing, independent sealed medicine bags are used for dispensing, and the medication instructions are thermally printed on the independent sealed bags. If the patient selects periodic dispensing, a medicine box is used for dispensing.

[0020] Preferably, the abnormal alarm includes tablet jamming, low inventory, and dose overlimit.

[0021] The beneficial effects of the present invention are as follows: 1. In the present invention, by extracting the patient's prescription information, dynamically counting using an infrared sensor and an optical counter, precisely cutting with a laser cutting head or a pressure blade, and weighing and verifying the cut medicines, the medicine dispensing accuracy is greatly improved, meeting the precise medication needs of patients, improving the patient's treatment effect, and thus reducing the probability of adverse reactions in patients.

[0022] 2. In the present invention, the intelligent control module is connected to the hospital HIS system to automatically synchronize the medication plan, and also has an abnormal alarm function. Once situations such as tablet jamming, low inventory, and dose overlimit occur, it can promptly remind for handling, improving the medicine dispensing efficiency and accuracy. While ensuring the medication safety of patients, it reduces the continuous monitoring time of medical staff for the medicine dispensing process, avoids medicine dispensing errors caused by human negligence, reduces the work pressure of medical staff, and improves the efficiency and quality of the overall medical work.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Refer to Figure 1As shown in the figure, the present invention provides an automatic medicine dispensing machine with drug recognition, including: a prescription information acquisition module, which is used to acquire patient prescription information based on the patient's prescription, including the drug name, dosage form, dosage, and administration time.

[0027] A drug recognition module, which is used to recognize the target drug from the built-in drug database of the device based on the patient prescription information by using a high-resolution camera + AI image recognition algorithm.

[0028] In a specific embodiment, the high-resolution camera + AI image recognition algorithm is used to recognize the color, shape, indentation, and packaging information of the drug, and also supports OCR character recognition to read the drug name, dosage, and expiration date information on the medicine board.

[0029] A flexible sorting unit, which is used to sort the target drug from the built-in drug database of the device by using a silica gel suction cup or a micro manipulator based on the patient prescription.

[0030] In a specific embodiment, the flexible sorting unit includes a counting module, a cutting module, and a weighing module.

[0031] The counting module is used to extract the dosage in the patient prescription and dynamically count the target drug by using an infrared sensor and a photoelectric counter.

[0032] The cutting module is used to judge whether the target drug needs to be cut based on the patient prescription. If the target drug needs to be cut, the target drug is cut based on the dosage form of the target drug.

[0033] The weighing module is used to weigh the cut target drug to judge whether it meets the accuracy requirements.

[0034] In the present invention, by extracting the patient prescription information, dynamically counting by using an infrared sensor and a photoelectric counter, precisely cutting by combining a laser cutting head or a pressure blade, and weighing and verifying the cut drug, the medicine dispensing accuracy is greatly improved, meeting the accurate medication needs of patients, improving the treatment effect of patients, and further reducing the probability of adverse reactions in patients.

[0035] It should be noted that the judgment of whether the accuracy requirement is met is specifically as follows: extract the weight of the target drug after cutting, compare it with the weight of the uncut target drug to obtain the cutting ratio of the target drug, compare it with the initial cutting ratio to obtain the difference in the cutting ratio, and compare the difference in the cutting ratio with the cutting ratio range stored in the device's built-in drug database. If the difference in the cutting ratio is within the cutting ratio range stored in the device's built-in drug database, it is determined that the accuracy requirement is met. The initial ratio refers to, for example, if the standard single-dose weight of a certain drug is 100 mg and the dose of this drug in the patient's prescription is 50 mg, then the initial ratio is

[0036] In a specific embodiment, the method for determining whether the target drug needs to be cut is specifically implemented as follows: extract the dosage in the patient's prescription, extract the standard single-dose of the target drug from the device's built-in drug database, and compare them. If the dosage in the patient's prescription is less than the standard single-dose of the target drug extracted from the device's built-in drug database, it is determined that the target drug needs to be cut. If the dosage in the patient's prescription is greater than or equal to the standard single-dose of the target drug extracted from the device's built-in drug database, it is determined that the target drug does not need to be cut.

[0037] It should be noted that if the target drug has scoring lines, it is cut according to the scoring lines.

[0038] In a specific embodiment, the method for cutting the target drug based on the dosage form of the target drug is specifically implemented as follows: extract the dosage form of the target drug. If the dosage form of the target drug is tablet-shaped, use a laser cutting head to cut the target drug. If the dosage form of the target drug is capsule-shaped, use a pressure blade to cut the target drug.

[0039] The dispensing and labeling module is used for packaging and labeling the target drug.

[0040] In a specific embodiment, the dispensing and labeling module supports the selection of the patient's dispensing method. The dispensing methods are divided into dispensing by times and dispensing in cycles. If the patient selects dispensing by times, use an independent sealed medicine bag for dispensing, and at the same time thermally print the medication instructions on the independent sealed bag. If the patient selects dispensing in cycles, use a medicine box for dispensing.

[0041] It should be noted that the selection of the dispensing method, the independent sealed medicine bag, and the medicine box support blind bump identification. The medication instructions include the drug name, dosage, QR code, where the QR code is used for traceability, and also include the medication time, such as morning, noon, and evening.

[0042] The intelligent control module uses an STM32 / Raspberry Pi as the main control chip, connects to the hospital HIS system, automatically synchronizes the generation of the medication plan, and also has an abnormal alarm function.

[0043] In the present invention, the intelligent control module is connected to the hospital HIS system to automatically synchronize the medication plan, and also has an abnormal alarm function. Once situations such as tablet jamming, low inventory, and dose overrun occur, it can promptly remind for handling, improving the efficiency and accuracy of medicine dispensing. While ensuring the medication safety of patients, it reduces the continuous monitoring time of medical staff for the medicine dispensing process, avoids medicine dispensing errors caused by human negligence, reduces the work pressure of medical staff, and improves the efficiency and quality of the overall medical work.

[0044] In a specific embodiment, the abnormal alarm includes tablet jamming, low inventory, and dose overrun.

[0045] The tablet jamming specifically means that an optoelectronic sensor and a vibration device are installed at the medicine outlet of the medicine dispenser. When the tablet passes normally, the sensor will generate corresponding signal changes. Once the tablet jams, the signal will be abnormal. At this time, the vibration device is started, and the vibration device separates the adhered tablets through amplitude control. If the medicine is still in a jammed state, an abnormal alarm is given.

[0046] For the low inventory, a high-precision weight sensor is installed at the bottom of the medicine storage container of the medicine dispenser. When the medicine storage container is full of medicine, the weight at this time is recorded as the initial value. As the medicine is continuously dispensed, the weight gradually decreases. According to the single-piece weight of the medicine and the preset safety inventory quantity, the corresponding weight threshold is calculated. When the weight sensor detects that the weight of the medicine storage container is lower than this threshold, the system identifies it as a low inventory state, and an abnormal alarm is given.

[0047] For the dose overrun, after weighing the cut target medicine, if it is judged that it does not meet the accuracy requirements, an abnormal alarm is given.

[0048] It should be noted that the prescription information acquisition module is connected to the drug identification module, the drug identification module is connected to the flexible sorting unit, the flexible sorting unit is connected to the packaging and labeling module, the prescription information acquisition module, the drug identification module, and the flexible sorting unit are simultaneously connected to the intelligent control module, and the counting module in the flexible sorting unit is connected to the cutting module, and the cutting module is connected to the weighing module.

[0049] The above content is only an example and explanation of the concept of the present invention. Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they should all fall within the protection scope of the present invention.
