Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.
The embodiment of the present specification relates to a medicine flow verification technology in a home environment (for example, home, community, etc.), and may be applied to a group scene in which medication management is required for the elderly, etc. in the home environment. In view of the problems of low efficiency and poor accuracy of the medicine circulation verification technology in the home environment in the prior art, the embodiment of the specification provides an improved technical scheme.
Referring to fig. 1, the present specification provides a drug circulation verification system, which may include a drug filling section 1, a drug extracting section 2, and a drug dispensing section 3. The medicine filling part 1 is provided with a plurality of medicine storage positions for storing different medicines, a medicine feeding channel for filling the medicine storage positions with the medicines, and a first medicine identification module. The first medicine identification module can be used for identifying whether the medicine filled into the medicine storage bin is a target medicine; allowing the drug to fill the drug storage bin when the drug is a target drug; when the drug is not the target drug, refraining from filling the drug storage bin with the drug and triggering a perceptible cue. The medicine extracting unit 2 may be configured to extract a set number of medicines from the medicine storage space when the medication timing arrives. The medicine dispensing unit 3 may be configured to dispense the medicine extracted by the medicine extracting unit 2. It should be noted that in the embodiments of the present specification, the medicine filled in the medicine storage space is unpacked medicine (i.e. medicine particles, such as tablets, pills, capsules, etc.).
Since the medicines are verified by the medicine filling part 1 and the medicine extracting part 2 before being dispensed by the medicine dispensing part 3, the probability that the medicine dispensing part 3 delivers wrong medicines or doses of wrong medicines is avoided (or greatly reduced), and the accuracy of medicine circulation verification in a home environment is improved; moreover, compared with the manual drug and dose verification, the mode of automatically verifying the drug and the dose by using the drug circulation verification system also greatly improves the drug circulation verification efficiency in the household environment.
The medicine circulation verification system in the embodiment of the present specification may be a small intelligent medicine box device in physical entities. This intelligence medical kit equipment can place and use in the environment at home. As will be appreciated by those skilled in the art, one or more human-machine interfaces may be provided on the intelligent medicine-box apparatus to facilitate information interaction between users, such as drug loaders, and the intelligent medicine-box apparatus. In some embodiments, the human-machine interface may include, for example, a touch-sensitive display screen, a voice input/output interface, a physical manipulation component (e.g., physical buttons, etc.), and the like.
Referring to fig. 2, in some embodiments, the medicine loading portion may include a medicine feeding passage 12, a rotary disk 13, a medicine cartridge rotating holder 14, a plurality of medicine cartridge positions 15, a motor driving shaft (not shown in fig. 2), and the like. The medicine feeding channel 12, the medicine bin rotating bracket 14 and the motor driving shaft are arranged on the system bracket 11. Wherein, the medicine feeding channel 12 is fixed on the system bracket 11, and the medicine cabin rotating bracket 14 and the motor driving shaft can perform rotary motion relative to the system bracket 11. The rotary disc 13 is positioned below the medicine feeding channel 12, the plurality of medicine storage bin positions 15 are positioned below the rotary disc 13, and the edge of the rotary disc 13 is provided with a medicine feeding opening 17 for controlling the opening and closing of the medicine feeding channel 12. The rotary disk 13 may be connected to a motor drive shaft via a disengageable transmission mechanism (e.g., a disengageable gear, etc.) to drive the rotary disk 13 in a rotary motion about the motor drive shaft. The plurality of medicine storage bin positions 15 are fixed on the medicine bin rotating bracket 14 and can rotate synchronously with the medicine bin rotating bracket 14. The medicine bin rotating support 14 is connected with a motor driving shaft through another clutch type transmission mechanism (such as a clutch gear) so as to drive the medicine bin rotating support 14 to rotate around the motor driving shaft, and further synchronously drive the medicine storage bin positions 15 to rotate around the motor driving shaft. The plurality of drug storage positions 15 are circumferentially and uniformly distributed with respect to the motor drive shaft. It should be noted that although the rotary disc 13 and the plurality of drug storage locations 15 may each be rotatable about the motor drive shaft, the rotary movement of the rotary disc 13 and the plurality of drug storage locations 15 may be asynchronous, i.e. there may also be relative movement between the rotary disc 13 and the plurality of drug storage locations 15.
In the normal state, the medicine inlet opening 17 is staggered with the medicine feeding channel 12, that is, the medicine inlet opening 17 is not located under the medicine feeding channel 12 in the normal state, in this case, no matter whether each medicine storage bin 15 rotates, the medicine feeding channel 12, the medicine inlet opening 17 and the medicine storage bin 15 cannot be communicated, and the medicine cannot be filled into any medicine storage bin 15 through the medicine feeding channel 12. On the premise that the medicine inlet opening 17 synchronously rotates to the position right below the medicine adding channel 12 along with the rotary disk 13 and is kept, when one medicine storage bin 15 rotates to the position right below the medicine adding channel 12 along with the medicine storage bin rotating bracket 14 and is kept, the medicine adding channel 12, the medicine inlet opening 17 and the medicine storage bin 15 are communicated, and medicines can be filled into the medicine storage bin 15; in this way, the medicine storage positions 15 can be alternately moved to the lower part of the medicine feeding channel 12 by the rotation of the rotary disk 13 and the medicine storage positions 15, so that the medicine filling of the medicine storage positions 15 is realized.
Continuing with fig. 2, the storage 15 needs to be provided in multiple numbers, considering that the user may need to take multiple drugs each time. To facilitate the circulation verification of the drugs, the individual drug storage locations 15 should be spaced apart and each drug storage location 15 can only store the same drug. For example, in an exemplary scenario, when a user desires to take three drugs, omeprazole, clarithromycin and amoxicillin, one reservoir may be filled with omeprazole, another reservoir with clarithromycin, and a third reservoir with amoxicillin.
In some embodiments, in order to further improve the accuracy of the drug circulation verification in the home environment, the drug filling part is further provided with an identity module. The identification module may be configured to identify a drug filler and determine whether to allow the drug filler to initiate a drug filling request based on the identification. When the drug filler is authenticated, the system may allow the drug filler to initiate a drug fill request (i.e., the system opens operating rights to the drug filler); when the drug filler fails the authentication, the system prohibits the drug filler from initiating a drug filling request (i.e., the system does not open operating privileges to the drug filler), and may output an alarm prompt via a human-machine interface. In this manner, only authorized persons may initiate a drug fill request to the drug flow verification system. The authorized person may be, for example, a family member, a family doctor, or a professional care worker of the drug user who has a complete civil activity ability. In some embodiments, the identification mode of the identity recognition module may include, but is not limited to, face recognition, fingerprint recognition, voiceprint recognition, password mode, and the like.
In some embodiments of the present description, allowing the drug to fill the drug storage location may refer to: the medicated channel is opened to allow the drug filler to perform a drug filling operation. Correspondingly, prohibiting filling of the drug storage locations with the drug may refer to: the medicine feeding channel is kept closed, so that a medicine filler is forbidden to fill the medicine storage bin with the medicine through the medicine feeding channel. For example, in the embodiment shown in fig. 2, the above-mentioned allowing the drug filler to perform the filling operation may refer to: when the medicine is the target medicine, the medicine inlet opening 17 is rotated from the normal position staggered from the medicine adding passage 12 to the position located right below the medicine adding passage 12 and held.
In some embodiments, the first drug identification module may collect drug information of a drug filled into the drug storage bin, compare the drug information with pre-stored drug information, and determine whether the drug to be filled is a target drug according to a comparison result. The pharmaceutical information may include, but is not limited to, name, manufacturer, specification (e.g., color, shape, size, form (capsule/tablet, etc.)), etc. Before filling the medicine (for example, after the medicine filler passes the authentication), the medicine information of the medicine which the user needs to take can be pre-entered. Wherein the target medicine is the medicine needed by the user. For example, in an exemplary embodiment, when the medicines to be taken by the user are omeprazole, clarithromycin and amoxicillin, if the medicine filled in the medicine storage is acetylspiramycin at this time, the first medicine identification module may find that acetylspiramycin is not the target medicine after acquiring the medicine information of acetylspiramycin and comparing the acquired medicine information with the pre-stored medicine information corresponding to omeprazole, clarithromycin and amoxicillin.
In some embodiments, the input means for entering the drug information of the drug that the user needs to take the drug in advance may include, but is not limited to, any one of the following means:
1. photographing a medicine to be filled, and inputting medicine information by an Optical Character Recognition (OCR) technology;
2. importing medicine information by inputting two-dimensional code information on medicine packages;
3. inputting medicine information in a self-defining mode, such as importing historical medicine information, or self-making two-dimensional code scanning and inputting;
4. and inputting medicine information in a voice interaction mode.
Referring to fig. 3, in some embodiments, the first medicine identification module may be a visual identification processing module 16, and the visual identification processing module 16 may collect an image of the medicine filled into the medicine storage bin, extract medicine information from the image, compare the extracted medicine information with pre-stored medicine information, and determine whether the medicine to be filled is the target medicine according to a comparison result. Of course, this is merely an exemplary illustration, and in other embodiments, the first medicine identification module may be replaced by any other device or component that can perform similar functions. In an exemplary embodiment, the visual recognition processing module may include a camera and image processing software, wherein the camera is configured to collect drug images of drugs filled into the drug storage bin, and the image processing software is configured to extract drug information from the drug images, compare the extracted drug information with pre-stored drug information, and determine whether the drug to be filled is the target drug according to a comparison result.
In addition, after the medicine feeding channel, the medicine inlet opening and the medicine storage bin X are communicated, the medicine filling part can also judge whether the medicine storage bin X is occupied currently (namely whether a medicine exists in the medicine storage bin) by utilizing the visual identification processing module before the medicine is filled into the medicine storage bin X; if the medicine storage bin X is not occupied currently, a medicine filler can fill medicines into the medicine storage bin X through the medicine feeding channel and the medicine inlet opening; if the medicine storage bin X is occupied, the medicine bin rotating bracket can be triggered to rotate so as to judge whether the medicine storage bin Y adjacent to the medicine storage bin X is occupied. In extreme cases, if all the drug storage bins are occupied, a perceptible cue can be output to remind the drug filler to handle the process.
In some embodiments, the medicine extracting part may include a negative pressure pick-up mechanism, a multi-directional movement mechanism, a first counting module, and the like. The negative pressure picking mechanism may be configured to pick up the medicines from the medicine storage bin to a set number one by one based on a negative pressure adsorption manner and supply the set number of medicines to the medicine dispensing portion when the medicines are the target medicines. The multi-directional movement mechanism can be used for driving the negative pressure picking mechanism to move in multiple directions relative to the medicine storage position so as to pick up the medicines. The first counting module may be configured to count the number of drugs picked up by the negative pressure pickup mechanism. The medicine is extracted one by one through the proper negative pressure picking mechanism, so that the damage to the medicine in the circulation process can be reduced or avoided, and the medicine counting statistics of the follow-up first counting module can be facilitated. The multi-directional movement mechanism refers to a movement mechanism capable of moving in multiple directions. It will be appreciated by those skilled in the art that in other embodiments, any other suitable picking mechanism may be used to pick up the medicines one by one, as required, and therefore, the embodiments of the present disclosure are not limited thereto.
Referring to fig. 3, in some embodiments, the medicine extracting part may include an air pump 21, a displacement table 22, an extracting motor 23, a gear 24, a rack guide 25, and a suction nozzle 26. The air pump 21 and the displacement table 22 are arranged on the system bracket 11, and the air pump 21 is used for providing a power source for extraction and release operations; the displacement table 22 is rotatable with respect to the system frame 11 so that the medicine pellets taken by the suction nozzles 26 can be placed in a designated temporary medicine storage space (i.e., a dispensing passage of the medicine dispensing portion mentioned below) and so that the first counting module can count the medicine pellets. The extraction motor 23, the gear 24 and the rack guide rod 25 are arranged on the displacement table 22, the gear 24 is fixed on a rotating shaft of the extraction motor 23, and the rack guide rod 25 is meshed with the gear 24. The suction nozzle 26 is an extraction actuator, and the suction nozzle 26 may be disposed at a lower end of the rack guide 25 and may be connected to the air pump 21 through an air path. When the gear 24 is driven by the extraction motor 23 to rotate, the rack guide rod 25 is synchronously driven to move upwards or downwards, and then the suction nozzle 26 is driven to move downwards into the medicine storage bin or move upwards out of the medicine storage bin. Specifically, when the rack guide rod 25 moves downward to make the suction nozzle 26 contact with the medicine in the medicine bin (for example, the suction nozzle 26 can sense the medicine by a pressure sensor or a contact sensor mounted on the suction nozzle 26), the air pump 21 sucks air from the suction nozzle 26, so that the suction nozzle 26 sucks one medicine due to negative pressure deformation; then the extraction motor 23 rotates reversely to move the rack guide rod 25 upward; when the suction nozzle 26 carrying the medicine is moved out of the medicine storage position (for example, the suction nozzle 26 carrying the medicine can be sensed by a visual sensor or an obstacle detection sensor), the displacement table can rotate at an angle, so that the suction nozzle 26 carrying the medicine is moved to the inlet end of the designated temporary medicine storage space, and at the moment, the air pump 21 inflates the suction nozzle 26, so that the suction nozzle 26 releases the medicine to the designated temporary medicine storage space due to pressurization deformation; thereby achieving the purpose of extracting the medicine. It can be seen that in the embodiment shown in fig. 3, the air pump 21, the suction nozzle 26, and the like may form a negative pressure pickup mechanism; the displacement table 22, the extraction motor 23, the gear 24, the rack guide 25, and the like may form a multidirectional movement mechanism.
In some embodiments, the first counting module may be a contact counter (e.g., a crash counter, etc.) or a non-contact counter (e.g., a photosensor, etc.). When the first counting module confirms that the target medicine in the designated temporary medicine storage space has been accumulated to a set data amount (for example, to a dose of two tablets taken at a time) by counting, the medicine extracting part is triggered to stop extracting the target medicine. In some embodiments, one or more medicine extracting parts can be arranged according to actual needs; when the system is provided with one drug extraction section, after the drug extraction of one target drug (e.g., omeprazole) is completed, the drug extraction section may continue the drug extraction of the next target drug (e.g., clarithromycin) until the drug extraction of all target drugs (e.g., omeprazole, clarithromycin, and amoxicillin) is completed.
In some embodiments, the medicine dispensing portion may include: the drug delivery device comprises a distribution channel, a second counting module, a second drug identification module and a drug collection box. Wherein the dispensing passage has a normally closed outlet, the dispensing passage being operable to receive the medicine extracted by the medicine extracting portion. The second counting module may be configured to count the number of drugs in the dispensing channel, and prohibit dispensing of the drugs and trigger a perceivable cue when the number of the drugs in the dispensing channel does not match a set number. The second medicine identification module can be used for identifying whether the medicine in the distribution channel is the target medicine; when the drug is not the target drug, dispensing of the drug is prohibited and a perceptible cue is triggered. When the medicine in the distribution channel is the target medicine and the quantity of the medicine is matched with the set quantity, the medicine is allowed to be distributed.
The medicine collecting box corresponds to the normally closed outlet of the distribution channel; the normally closed outlet is opened when the medicines are target medicines and the number of the medicines is matched with the set number, so that the medicines in the distribution channel fall into the medicine collecting box; when the medicine is not the target medicine or the number of the medicines is not matched with the set number, the normally closed outlet of the distribution channel is maintained in a normally closed state, and the medicine in the distribution channel cannot enter the medicine collecting box, so that the medicine is forbidden to be distributed; when the medicines in the distribution channel are target medicines and the number of the medicines is matched with the set number, the normally-closed outlet of the distribution channel is opened, and the medicines in the distribution channel can enter the medicine collecting box, so that the medicines are allowed to be distributed. When the user needs to take all the medicines once and all the medicines fall into the medicine collecting box, the user can trigger the sensible prompt to remind the user to take the medicines.
In some embodiments, the second medicine identification module may employ a visual identification processing module, and in other embodiments, the second medicine identification module may be replaced with any other device or component capable of performing similar functions.
In some embodiments, the second counting module may be a contact counter (e.g., a crash counter, etc.) or a non-contact counter (e.g., a photosensor, etc.). In other embodiments, the second counting module may also be a pressure sensor or a retransmission sensor, and since the single particle weight of each type of medicine is fixed, it may also be estimated whether the number of medicines reaches a set number by measuring the weight of the medicine.
As shown in fig. 1, in order to facilitate medication administration and follow-up medication event tracing, the medicine circulation verification system may further include a chain storage unit 4 in addition to the medicine filling unit 1, the medicine extracting unit 2, and the medicine dispensing unit 3. The chain storage unit 4 may be configured to chain store the medicine flow processing record of the medicine filling unit, the medicine flow processing record of the medicine extracting unit, and the medicine flow processing record of the medicine dispensing unit based on a block chain technique. The record of the drug circulation processing of the drug loading unit may include, for example, an authentication record, a drug loading record (e.g., a drug bin number, a drug storage record for each drug bin, etc.), a drug information record (i.e., a record of drug information actually collected during loading, etc.), and the like. The medicine flow processing record of the medicine extracting unit may include, for example, a medicine extraction record. The medicine flow processing record of the medicine dispensing unit may include, for example, a medicine review record, a medicine dispensing record, and the like.
As shown in fig. 4, since the drug flow processing record is synchronized to the blockchain storage server based on the blockchain technology, it is possible to prevent the relevant personnel from tampering with the drug flow processing record, thereby facilitating the follow-up medication event tracing. Of course, in other embodiments, the drug flow processing records may also be synchronized to other secure storage servers according to actual needs. It is understood that the data synchronized to the blockchain storage server may be a hash value corresponding to the drug stream processing record, and in other embodiments, the data synchronized to the blockchain storage server may also be a hash value corresponding to the drug stream processing record + the digital signature, etc. In fig. 4, the user is a user (e.g., a drug filler) of the drug flow verification system, and the user needs to perform registration authentication with the authentication server in advance, so that the subsequent authentication server cooperates with the identity module for identifying the drug flow verification system to complete identity identification and verification of the user. In fig. 4, the processing server may act as a front-end server, and may perform data forwarding and the like.
In other embodiments, in addition to the above-mentioned drug circulation processing records, in order to make the virtual drug data records (i.e. pre-stored drug information) correspond to the actual drug storage situation, visual identification is performedThe identification processing module (taking the visual identification processing module as an example) can also verify the filled medicine by using a double verification scheme of chain data for each individual medicine storage bin: after the visual recognition processing module photographs the filled medicine, extracting characteristic information (such as medicine grain color, shape, size, form and the like) of medicine image information for digitalization, and generating a current medicine characteristic field MCiAt the same time, each storage bin also corresponds to a current status field CSi，CSiIs generated by the current drug characteristic field MCiAnd a previous state feature field CSi-1After certain logic operation (and, or, not, xor, etc. or combination of these logic operations), the single-direction function is obtained. For example, in an exemplary embodiment, the CSiThe calculation of (d) can be as follows:
CS0set Value (Defined Value);
meanwhile, since the historical medicine records stored in each medicine storage bin can be inquired, the system can acquire the characteristic values of the medicines according to the historical records of the stored medicines, and can verify whether the current medicine storage bin has abnormal medicine storage conditions or not by using the same algorithm of the storage unit. Once the medicine is mistakenly stored in the incorrect medicine storage bin, the incorrect medicine storage bin can be found in time.
The perceptible prompt mentioned in the embodiments of the present specification may include, but is not limited to, a visual prompt (e.g., a graphic alarm prompt, a light alarm prompt, etc.), an audible prompt (e.g., an audio alarm, etc.), and the like.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.
It should be noted that, in the embodiments of the present specification, the user information (including, but not limited to, user device information, user personal information, etc.) and the data (including, but not limited to, data for analysis, stored data, presented data, etc.) referred to are information and data that are authorized by the user and are sufficiently authorized by the parties.
The present specification further provides a drug flow verification method, which can be applied to the drug flow verification system described above, and as shown in fig. 5, in some embodiments, the drug flow verification method may include the following steps:
s501, identifying whether the medicine filled into the medicine storage bin is a target medicine; allowing the drug to fill the drug storage bin when the drug is a target drug; when the drug is not the target drug, refraining from filling the drug storage bin with the drug and triggering a perceptible cue.
When a drug needs to be filled into the system, after the drug to be filled in each is prepared, the drug filler can initiate a drug filling request to the system through the human-machine interface. The system carries out identity verification on a medicine loader, and when the medicine loader passes the identity verification, the system can allow the medicine loader to initiate a medicine loading request (namely the system opens an operation authority to the medicine loader), and stores verification information and a verification result in a chain way; when the drug loader fails the authentication, the system prohibits the drug loader from initiating a drug loading request (i.e., the system does not open an operation right to the drug loader), and may output an alarm prompt through the man-machine interface and uplink-store the authentication information and the authentication result.
After the identity verification is carried out by a medicine loader, before medicines are loaded into the medicine storage bin, the system can acquire medicine information of the medicines loaded into the medicine storage bin, compare the medicine information with prestored medicine information, and determine whether the medicines to be loaded are target medicines or not according to a comparison result so as to avoid that a subsequent medicine loader mistakenly loads the medicines; when the medicine is not the target medicine, outputting an alarm prompt, and chaining and storing the collected medicine information and the identification result; when the medicine is the target medicine, the collected medicine information and the identification result can be linked and stored.
When the medicine is the target medicine, the system opens the medicine feeding channel, and a medicine loader can load a proper amount of medicine into the idle medicine storage bin. After the medicines are filled, the system can link the medicines such as the medicines filled in each medicine storage bin and the like on the filling record for storage, and close the medicine adding channel. In some embodiments, the filling of the empty drug storage locations with the appropriate amount of drug may be: the medicine is filled only once, so that the medicine effect is prevented from being influenced by long exposure time of the medicine outside. In other embodiments, the filling of the empty medicine storage bin with the proper amount of medicine may be: the medicine is filled for a plurality of times (for example, the medicine dosage of one day, three days or one week) once, so that the labor intensity of a medicine filler can be reduced, and the medicine filling efficiency can be improved.
And S502, extracting a set number of medicines from the medicine storage bin when the medicine taking time is up.
When the user needs to take the medicine, the system can automatically extract the medicines from the medicine storage bin to a set number one by one, and the medicine extraction records are linked and stored. The medicine extraction can be initiated by the system through a timing task or manually through an operation man-machine interface.
For example, in one exemplary embodiment, when a user needs to take a single dose: when two omeprazole grains, two clarithromycin grains and two amoxicillin grains are used, the information of the medicine which is needed to be taken by a user for one time and the dosage information thereof are stored in the system in advance; when a user needs to take medicine, the system can automatically extract two omeprazole grains from the medicine storage bin corresponding to the omeprazole, extract two clarithromycin grains from the medicine storage bin corresponding to the clarithromycin and extract two amoxicillin grains from the medicine storage bin corresponding to the amoxicillin.
S503, dispensing the extracted medicine.
To further reduce the probability of dispensing the wrong medication. The system can recheck the extracted medicines and the quantity thereof before distribution; if the check is passed, the dispensing is allowed and the drug dispensing record is chain stored. If the recheck is not passed, the dispensing is prohibited if the recheck is passed, and the drug recheck record is uplink stored.
In the medicine circulation verification method in the embodiment of the specification, before the medicines are distributed, medicine verification and dose verification are performed on the medicines, so that the probability of wrong medicine distribution or wrong medicine dose distribution is avoided (or greatly reduced), and the accuracy of medicine circulation verification in a home environment is improved; moreover, compared with the manual drug and dose verification, the mode of automatically verifying the drug and the dose by using the drug circulation verification system also greatly improves the drug circulation verification efficiency in the household environment.
