Description

The present invention relates to a chemical management system for managing the usage status of chemicals that are set on a tray and used in a medical field, and more specifically, partitions a tray to store chemicals in each section and use chemicals. The present invention relates to a chemical management system that grasps the presence or absence of each zone.
In addition, in addition to injections such as ampoules, vials, and contrast agents, pharmaceuticals include pharmaceuticals such as tablets and powders contained in boxes and bottles, and auxiliary chemicals used together with chemicals.

As a chemical management system that manages the usage status of chemicals used in medical settings by setting several chemicals in the tray in advance, the number of chemicals is obtained from the image data by photographing the chemicals set surface of the tray. Has been put to practical use (see, for example, Patent Document 1).
In this system, set information before use is saved, and after use, measurement work is performed in units of trays to detect changes in the quantity of chemicals. It is also possible to grasp accurately.

In addition, a number of compartments are formed on the upper surface of the drawer that can be withdrawn, and a chemical presence / absence detecting means is provided in each compartment, so that the state of use of the chemicals can be grasped for each compartment. A shelf device is also provided (see, for example, Patent Document 2).
In addition, if you place a proper number of chemical seats pre-mounted with electronic tags on the tray in an appropriate arrangement, and place each chemical on the seat of each chemical seat, A drug setting device has also been developed that can grasp the class setting status for each sitting tool by tag reading (see, for example, Patent Document 3).

In such a conventional medicine management system, in the case of the former imaging counting method (see, for example, Patent Document 1), only one or a small number of sensitive parts / detecting parts (sensors) are required. Some chemicals are difficult to detect depending on the color, transparency, etc., so such chemicals should be avoided or handled with care.
On the other hand, in the case of the latter individual detection method, a wide range of chemicals can be handled, whether direct detection (for example, see Patent Document 2) or indirect detection (for example, see Patent Document 3). Since the number of detection units (sensors) is large, the burden of manufacturing and maintenance is large.

As described above, since there are advantages and disadvantages depending on the type of conventional chemical management system, it is desired to develop and provide a combination of both advantages.
Therefore, it is a basic problem to improve the system so that an image that can be reliably detected in units of sections is obtained after following an imaging method with few sensors.
Moreover, it is a technical problem to solve the basic problem by simple modification so as not to impair the advantage of the imaging method that it is easy to manufacture and maintain.

  The medicine management system of the present invention (Solution means 1) was devised in order to solve such a problem, and an arrangement determining means for determining the arrangement of chemicals to be set in a tray in accordance with a dispensing instruction. A printing means for printing the chemical identification code on the printing paper placed on the inner bottom of the tray according to the arrangement; an imaging means for taking the printing paper together with the tray; and an identification code from the image And determining means for determining whether or not the chemicals are used.

  Further, the medicine management system of the present invention (Solution means 2) is the medicine management system of the solution means 1, wherein when the determination means can read the identification code, it is determined that the corresponding chemicals are used, When the identification code cannot be read, it is determined that the chemicals in the corresponding part are not used, and thus the presence / absence of use of the chemicals is determined based on the reading result.

  Furthermore, the medicine management system of the present invention (Solution means 3) is the medicine management system of the above solution means 2, wherein the arrangement determining means stores set data reflecting the arrangement, It is characterized in that the determination means also confirms the coincidence between the read result and the set data at the time of determination.

  The medicine management system of the present invention is (Solution means 4), which is the medicine management system of the above solution means 1 to 3, wherein the placement determining means registers the sizes of various kinds of medicines upon placement determination. The partition is also selected by referring to the data and partition data related to the removable partition that partitions the internal space of the tray into a plurality of sections.

  The medicine management system of the present invention is (Solution means 5), which is the medicine management system of the solution means 1 to 4, characterized in that the printing means prints the identification code in color. To do.

  In such a medicine management system of the present invention (Solution means 1), when a dispensing instruction is given, the arrangement of the chemicals in the tray is determined by the arrangement determining means in accordance with the instruction, and further, the arrangement corresponds to the arrangement. Since the chemical identification code is printed on the printing paper by the printing means in the arrangement, it will be manual work after that, but the printed paper is laid on the inner bottom of the tray and stacked on the removable partition. In addition, by storing in the tray, a number of compartments can be easily formed on the tray, and a chemical identification code can be attached to each compartment.

Then, chemicals are set in each compartment of the tray, the tray is used for medical activities such as surgery and treatment, and the returned tray is placed under the imaging device and left to the system. Then, again, the printing paper together with the tray is automatically taken from above, and the identification code of each section is read from the image, and the presence or absence of chemicals is determined based on the reading result. In this way, when performing image processing, instead of using a direct method for recognizing a wide variety of chemical images, it is an indirect method of reading a known identification code that appears and hides depending on the presence or absence of chemicals in the compartment. By adopting the method, it is possible to accurately determine whether or not chemicals are used on a partition basis.
Therefore, according to the present invention, it is possible to realize a chemical management system that can perform reliable individual detection in units of sections and that is easy to manufacture and maintain.

  In the medicine management system according to the present invention (solution 2), when the presence / absence of use of chemicals is determined based on the reading result, if the identification code cannot be read, the corresponding chemicals are not used. On the other hand, when the identification code can be read, it is determined that the chemicals in the corresponding part have been used, so that in addition to knowing whether or not the chemicals are used, it is possible to know what chemicals have been used. Moreover, since it can be understood from the read identification code, it can be determined whether the set data before use is stored or not.

  Furthermore, in the medicine management system of the present invention (solution 3), the set data stored using the fact that the set data before use is no longer essential for identifying the medicine as described above is By diverting it to the coincidence confirmation with the reading result of the identification code, the reliability of the determination is improved by utilizing redundant information.

  In the medicine management system of the present invention (solution 4), an appropriate partition is selected according to the size of the medicines to be set on the tray. In a simple manner, it is possible to prevent an undesired situation such as redoing work because chemicals do not fit in the compartment.

  Further, in the medicine management system of the present invention (solution 5), the color of the identification code printing makes the compartments into which the medicines are to be stored become clear at a glance. By properly using these colors, the amount of information can be increased without subdividing the identification code.

The structure and usage of a chemical management system are shown about Example 1 of this invention, (a) is an external appearance perspective view of a chemical management system, (b) is a block diagram of a control apparatus. The modification of this invention is shown, (a)-(d) all are the longitudinal cross-sectional schematic diagrams of a set tray. The modification of this invention is shown, (a)-(b) all are the external appearance perspective views of a chemical | medical agent management system.

With regard to such a chemical management system of the present invention, a specific mode for carrying out this will be described with reference to Example 1 shown in FIG.
In the illustrations, for the sake of simplicity, bolts and other fasteners, hinges and other couplers, batteries and other power sources, details of electric circuits and electronic circuits, etc. are not shown in the drawings. The illustrations focus on what is needed and what is relevant.

  About the Example 1 of the chemical | medical agent management system of this invention, the specific structure is demonstrated referring drawings. 1A is an external perspective view of a medicine management system 10 tailored to a medicine cart, and FIG. 1B is a block diagram of a control device 30.

  The medicine management system 10 is embodied as a medicine cart, and includes an imaging device 12, a printing device 15, a control device 30, an input device 31, and an output device 32 mounted on a cart 11 with casters, hand handles, and the like. And managing the usage status of the chemicals 8 as well as storing and transporting the set tray 20 in which the chemicals 8 are set in the set of the empty tray 21, the printing paper 16, and the partition 22. . The set tray 20 may be referred to as a storage tray 23, a pre-use tray 24, or a post-use tray 25 depending on usage conditions.

The empty tray 21 is illustrated as a shallow square dish-like box, but other tray containers may be used as long as the chemicals 8 can be stored side by side and carried by hand, placed on a desk, or put in and out of the storage compartment.
For the printing paper 16, paper-like materials slightly smaller than the inner surface of the empty tray 21 are used so as to fit on the inner bottom of the empty tray 21.
The partition 22 is formed of a lattice-like member having an equal pitch or unequal pits, or a part of which is cut out. The partition 22 is detachable so that it can be inserted into and removed from the empty tray 21. The internal space 21 is divided into a large number of sections.

  Since the cart 11 follows the imaging method, one or more shooting sections 13 containing the imaging device 12 are secured, and the temporary tray 21 and the set tray 20 (storage tray 23) are temporarily stored and transported. A large number of storage compartments 14 are secured. The storage section 14 suffices if the trays 20 and 21 can be stored and taken out. However, the imaging section 13 can take pictures of the set surface of the set tray 20 in addition to taking in and out the set tray 20 and temporarily placing it. In order to do so, the height is higher than the storage compartment 14, and the imaging device 12 is mounted facing down on the ceiling surface. In addition, if necessary, appropriate illumination, a sensor for detecting insertion and removal of trays, and the like are also attached.

The imaging device 12 employs, for example, a CCD camera and operates when the set tray 20 is placed in the photographing section 13 to take a picture of the tray 20 from above, but is placed on the inner bottom of the set tray 20. Since the identification code 17 is printed in color on the printing paper 16, a color photographable one is adopted so that the image can be accurately obtained.
The printing device 15 employs, for example, an ink-jet color printer, and prints the identification code 17 of the chemicals 8 in color on the printing paper 16 laid on the inner bottom of the empty tray 21. The code is printed.

  The control device 30 is composed of a programmable information processing device such as a so-called notebook personal computer, inputs a dispensing instruction from the input device 31 and causes the printing device 15 to print the identification code 17 and inputs image data from the imaging device 12. For example, the arrangement determination program 41, the printing program 42, the reading program 43, the determination program 44, and the counting program 45 are installed on the output device 32. Dispensing instruction data 51, dosage form data 52, partition data 53, set data 54, code data 55, and data areas of image data 56 are allocated to the memory.

The input device 31 only needs to be able to input the dispensing instruction data 51 to the control device 30, and may be a keyboard or a mouse attached to the control device 30. The communication unit downloads the dispensing instruction data from an external prescription order entry system or the like. But it ’s okay.
The output device 32 only needs to be able to output the use result of chemicals in a state where it can be visually recognized or in a state where data management is possible, and may be a display attached to the control device 30 or may be used as the printing device 15. Alternatively, another printing apparatus such as a dedicated printer or a communication unit that transmits electronic data may be used.

The dispensing instruction data 51 only needs to include identification codes 17 of some medicines 8 to be set on the tray 21, but the set name, the medicine name, the prescription number, the dispensing instruction number, the operation name, and the patient name. Etc. may be added. The identification code 17 is a code for specifying the chemicals 8, and a common chemical code that is usually used in other dispensing machines or the like is used.
The dosage form data 52 is obtained by preliminarily registering size data mainly for the outer dimensions of various chemicals 8, and the partition data 53 is obtained by previously registering partition size and arrangement data for each partition 22 having different sections. It is.

The set data 54 is data reflecting the arrangement of the chemicals 8 to be set in the empty tray 21 or set in the set tray 20, and the arrangement defining data collecting at least the set data of the identification code and the section position. And related data such as a set name and a technique name may be included.
The code data 55 is pattern information necessary for printing or reading the identification code 17, and data defining a 1D or 1.5D color bit code is registered in advance.
The image data 56 is a color image obtained by taking the medicine set surface of the set tray 20 with the image pickup device 12. In this device, an image taken for the post-use tray 25 among the set tray 20 is used. It has come to be.

  When the dispensation instruction data 51 in which the medicine 8 to be set in the empty tray 21 is designated by the identification code 17 is input, the arrangement determination program 41 stores the empty tray 21 in accordance with the dispensation instruction data 51 each time. The arrangement of the chemicals 8 to be set is determined, set data 54 reflecting the arrangement is stored, and the print program 42 is notified. The stored set data 54 is stored until it is referred to by the determination program 44 or is manually deleted, so that at least the same number or more as the storage compartments 14 can be accumulated. Further, when determining the arrangement, the arrangement determining program 41 refers to the dosage form data 52 to check the size of the set target drug 8 and refers to the partition data 53 to determine whether the set target drug 8 can be accommodated. The partition 22 with which it has was selected.

  The print program 42 controls the printing device 15 to print on the printing paper 16 every time the set data 54 is notified from the arrangement determination program 41. At that time, the print program 42 is set with reference to the set data 54. The identification code 17 is printed on the printing paper 16 in an arrangement corresponding to the arrangement of the target chemicals 8, and the identification code 17 is printed as a color bit code with reference to the code data 55 (for example, Japanese Patent Application Laid-Open No. 2005-260260). 2008-282104 and JP-A-2009-87192). Related data such as set names and drug names are not essential, but are preferably printed as much as possible.

  Each time the image data 56 is obtained, the reading program 43 tries to extract a code or recognize a code for the image data, and reads the identification code 17 from the image. When reading is attempted, priority is given to reading the set name for identifying the set data 54, and when arrangement data is obtained, code extraction is performed according to the classification corresponding to the arrangement. As a result, at least position information of each cut-out location and whether or not reading is possible at each location are output (see, for example, Japanese Patent Application Laid-Open No. 2008-287414 and Japanese Patent Application Laid-Open No. 2009-003721).

  The determination program 44 determines whether or not the medicine 8 is used based on the identification code reading result of the reading program 43. First, when the identification code 17 can be read, the medicine in the corresponding place in the post-use tray 25 is used. It is determined that the class 8 has been used, and when the identification code 17 cannot be read, it is determined that the corresponding part of the drug is not used, thereby determining whether or not the drug is used. Since the medicine 8 is immediately identified from the read identification code 17, it is possible to determine whether or not the medicine is used only from the identification code reading result. The determination program 44 also refers to the set data 54. Until the match is confirmed.

Specifically, the identification code read for the chemicals 8 that have been used based on the reading result, and the identification stored in the set data 54 as that of the chemicals 8 set in the section corresponding to the corresponding location If the codes match, it is determined to be good, and if they do not match, it is determined that some trouble such as a reading error or a tray difference has occurred.
The tabulation program 45 tabulates the usage amount of chemicals from the determination result of the determination program 44 in units of trays 20 or carts 11 and outputs the tabulation results to the output device 32.

About the chemical | medical agent management system 10 of this Example 1, the use aspect and operation | movement are demonstrated referring drawings. FIG. 1A is a perspective view showing a system use state.
As described above, the set tray 20 may be referred to as a storage tray 23, a pre-use tray 24, or a post-use tray 25 depending on the usage situation.

  Prior to use, blank printing paper 16 is set in a paper feeding unit such as a paper feeding tray of the printing apparatus 15, and a large number of empty trays 21 and partitions 22 are prepared with a margin if necessary. When the medicine management system 10 is used for the first time or when it is completely emptied and used again, the control device 30 is initialized to clear the accumulation of the dispensing instruction data 51 and the set data 54 and the medicines that may be used. The dosage form data 52 and the partition data 53 are set manually or downloaded with respect to 8 and the partition 22.

  The medicine management system 10 that can be used in this manner is first placed in a dispensing place such as a hospital pharmacy or a nurse center. When dispensing instruction data 51 is given to the control device 30, the decision program 41 causes the empty tray 21 to be placed. The arrangement of the medicines 8 to be set is determined in accordance with the dispensing instruction data 51, and is stored as set data 54. At this time, the dosage form data 52 and the partition data 53 are referred to to determine which size medicine. Since the partition 22 having a compartment that can also accommodate the class 8 is selected, and the partition state and the chemical size 8 are also reflected in the arrangement determination and the dispensing instruction data 51, the appropriate partition 22 is used naturally. Become.

Each time one set data 54 is created, the print program 42 refers to the set data 54 and the code data 55, and identifies the print data 16 to be printed in accordance with the arrangement of the chemicals 8 to be set in the empty tray 21. The code 17 and its arrangement are determined.
Then, the identification code 17 is printed on the printing paper 16 by the printing device 15, and the printing paper 16 having the identification code 17 printed in an arrangement corresponding to the section of the appropriate partition 22 is completed. Come out in the paper.

  When the printing paper 16 on which the identification code 17 is printed comes out, a dispensing operator such as a pharmacist or a nurse picks up the printed printing paper 16 and also sees the empty tray 21 and the partition 22 that fit. By picking it up, the printing paper 16 is laid on the inner bottom of the empty tray 21 with the printing surface of the identification code 17 facing up, and the partition 22 is inserted into the empty tray 21. At that time, it is visually confirmed that the identification codes 17 are securely contained in the respective sections of the partition 22 that overlap the print paper 16 from above. If the fit is bad, the direction of the partition 22 is changed so that it fits.

  Further, when the dispensing operator puts medicines 8 such as injection ampules corresponding to the identification code 17 one by one into each section of the partition 22 and all the identification codes 17 are hidden by the medicines 8 and become invisible. Then, the set tray 20 is completed. It should be noted that the dispensing operator decides where to put the chemicals 8 when the identification code 17 is printed in advance on the chemicals 8 and that the identification code 17 on the printing paper 16 matches. Even if the identification code 17 is not printed on the chemicals 8, if the chemical name is printed on the chemicals 8, the chemical name may be printed on the printing paper 16 together with the identification code 17. If another type of identification code such as a bar code is printed on the class 8, an auxiliary tool or the like that reads it and displays the identification code 17 may be used.

The completed tray 20 thus completed is stored and placed in the storage section 14 of the cart 11 as the storage tray 23 while the medicine management system 10 remains in the dispensing place.
When the above set operation is repeated several times and the required number of storage trays 23 are collected in the storage compartment 14 of the cart 11, they are moved from the dispensing place to a use place such as an operating room by moving the cart. At the place of use, a medical practitioner such as a doctor or a nurse removes the storage tray 23 from the storage compartment 14 and uses it as a pre-use tray 24. After use, the storage tray 23 serves as a post-use tray 25. Returned to 10.

In the returned tray 25 after use, the chemicals 8 used in the operation or the like are taken out and are lost. Therefore, the tray 25 can be used immediately, later, at the place of use, or at any other place after the cart is moved again. In order to confirm the use status, the cart 11 is manually placed in the photographing section 13 once.
Then, the post-use tray 25 is taken from above by the imaging device 12, and the image data 56 is taken into the control device 30. In the image data 56, the partitioning state by the partition 22 and the medicine storage state in each section are shown, and the identification code 17 appears in the section where the medicines 8 are taken out, but the medicines 8 remain. The identification code 17 is hidden in the section.

  When the image data 56 is input, the reading program 43 reads the identification code 17 based on the code data 55, and the determination program 44 determines whether or not the medicine 8 is used based on the identification code reading result of the reading program 43. Determined. Specifically, an identification candidate area is cut out from the image data 56, position information of each cut-out location and whether or not the identification code can be read at each location are output, and based on this, when the identification code 17 can be read It is determined that the corresponding chemicals 8 in the post-use tray 25 are used, and when the identification code 17 cannot be read, it is determined that the corresponding chemicals are not used.

  Further, the determination program 44 also checks whether or not the previous determination result matches the set data 54. Specifically, the identification code read for the chemicals 8 that have been used based on the reading result, and the identification stored in the set data 54 as that of the chemicals 8 set in the section corresponding to the corresponding location If the codes match, it is determined that there is no problem in the previous determination result, and if they do not match, there is a problem. Then, the total amount of chemicals used is totaled for each tray 20 based on the determination result of the determination program 44 by the total program 45, and the total result is output from the output device 32. When there is a problem in the determination, the fact is output from the output device 32 along with the total result, and is also notified by a display on the control device 30 or a buzzer sound.

In this way, if the post-use tray 25 is manually placed in the photographing section 13, the post-use tray 25 is automatically photographed, and the presence or absence of use of the chemicals 8 is grasped for each post-use tray 25. The post-use tray 25 whose use status has been confirmed is manually removed from the photographing section 13 and returned to the storage section 14 or moved to another storage shelf or the like.
When the above operations are repeated for several storage trays 23 stored in the storage compartment 14 and the medicine management system 10 has finished its role, the medicine usage quantity is counted by the counting program 45 in units of carts 11. And output by the output device 32 and the drug management system 10 is returned to the dispensing site for subsequent use.

[Others]
When the post-use tray 25 is imaged from above, even if the central portion directly below the imaging device 12 is good, the inclination in the imaging direction increases toward the outside, and the identification code 17 there is blocked by the partition 22 so that an image can be taken. In order to easily prevent the loss, it is desirable to make the height of the partition 22 as low as possible, and the partition 22 should be high enough to prevent the chemicals 8 from rolling. The partitions 22 having different widths and heights may be properly used according to the size of the chemicals 8 (see FIGS. 2A to 2C). A plurality of small trays and partitions may be arranged on a normal size empty tray (see FIG. 2D).
In the above embodiment, the trays 25 after use are photographed one by one. However, when the trays 25 are small and a plurality of trays 25 can be placed side by side, a plurality of trays 25 may be photographed at once.

In the above-described embodiment, the imaging is performed in the imaging section 13. However, for example, the control device 30 and the printing device 15 are separately provided to secure a wide imaging area on the top plate of the cart 11. Alternatively, the imaging device 12 may be installed above, and the post-use tray 25 may be arranged on the top board so that it can be taken from above (see FIG. 3A). In that case, it is preferable to cover the top plate as much as possible with a shielding plate or the like that blocks outside light. It is also possible to cut off fluorescent light or other disturbance light by frequency-discriminating the illumination for photography provided to the imaging device 12 by blinking at a specific frequency.
In the said Example, although the control apparatus 30 and the printing apparatus 15 were mounted on the top plate of the cart 11, they are stored in the cart 11, and an operation part and an extraction part are exposed to the front, It may be used by being pulled out (see FIG. 3B).

In the above embodiment, the contents of the imaging and determination are limited to whether or not the chemicals 8 related to the post-use tray 25 are used. However, the suitability of the chemicals 8 set related to the set tray 20 before use is checked. You may do it.
In the above embodiment, the printing paper 16 is laid on the inner bottom of the empty tray 21 and the partition 22 is inserted into the empty tray 21 by hand. The pick-up operation 22 may be automated by an appropriate storage device or robot that cooperates with the medicine management system 10.

  The medicine management system of the present invention is not limited to the mobile type such as the above-described medicine cart, but may be embodied as a fixed type such as a medicine storage or a tray storage shelf. Not limited to this, it may be embodied in a distributed system, and can be used in various medical sites such as for operating rooms, ICUs, and wards.
