Description

  The present invention relates to a safety cabinet and a dispensing system used in industrial fields such as medical care, regenerative medicine, and pharmaceuticals.

  Due to concerns about the effects of exposure to high-risk medications, such as pharmacists, in the work of pharmaceuticals, especially high-risk medications such as anticancer drugs, dispensing was provided in a dedicated dispensing room It is known to perform in a safety cabinet (see, for example, Patent Document 1). The safety cabinet forms a semi-sealed work space inside the work cabinet except for the work opening, sucks air in the work space, and creates a negative pressure in the work space. This prevents the vapor and powder from flowing out to the worker side. Dispensing in the safety cabinet can improve worker safety.

  In dispensing using a safety cabinet, it is natural to work while looking at a prescription (recipe). For example, in the preparation of an anticancer drug, the patient has a great influence depending on the drug to be handled and the amount thereof, and therefore it is necessary to accurately match the amount of the drug and the like. Therefore, a predetermined check is performed at the time of dispensing. In addition, a double check is performed by the dispensing operator (worker) and the dispensing auditor.

Here, in the dispensing procedure for high-risk drugs such as anticancer drugs, for example, as a preparatory work, an operator or the like first wears personal protective equipment (white coat, mask, cap, goggles, gloves, etc.).
Next, preparation for dispensing is performed. First, a safety cabinet is prepared, and necessary instruments and medicines are prepared in the safety cabinet based on a prescription.

Next, dispensing is performed according to a prescription.
For example, there is an operation of “weighing a solution in which a drug is dissolved from a container (vial) by an amount described in a prescription using a syringe and injecting this solution into an infusion bag”.
First, (a) a diluent of a predetermined species and amount is poured into a container (vial) by a syringe and dissolved and diluted.
Next, (b) the drug diluted at the above predetermined dilution rate is weighed with a syringe by an amount based on the prescription.
Next, (c) the above-measured drug is injected into the infusion bag.
In each stage of the above operations (a), (b), and (c), double confirmation of prescription description items by the operator and the inspector is performed, such as whether or not the measured amount is incorrect.
Thereby, the dispensing operation in the safety cabinet is finished, and the dispensed medicine is carried out.
In the double confirmation at each stage of the above work, both the pharmacist and the auditor who carry out the work stamp or sign the prescription. The working pharmacist and the auditor can be identified by the marks and signs.
The dispensing procedure as described above suppresses the occurrence of problems in dispensing, including exposure of workers to drugs.

JP2011-87999A

  By the way, in the above-mentioned dispensing, the dispensing operation and its check are performed using a prescription. During dispensing work, the operator checks the prescription with the prescription attached to the frame of the safety cabinet with a magnet. In this case, for an operator who is dispensing in the vicinity of the safety cabinet, the distance to the prescription attached to the frame part of the opening of the safety cabinet or the shutter part of the opening is too short, and the prescription Becomes difficult to see. In addition, the distance of the line of sight from the line of sight of the worker looking inside the working space to the line of sight of the worker confirming the prescription in front of the work space is long, making it difficult to repeat work and prescription confirmation. Become. From the above, in the safety cabinet, the workability of dispensing while looking at the prescription is poor, which may cause a mistake.

  In addition, the operator touches the prescription for checking, sealing, etc., and the possibility that the prescription is contaminated with the medicine to be dispensed cannot be denied. In addition, although working in the safety cabinet, because the equipment and drug containers are put in and out of the safety cabinet, it cannot be said that the drug dispensed in the dispensing chamber is not contaminated at all. .

  Therefore, when the auditor is in the dispensing room together with the worker, not only the worker but also the auditor needs to pay sufficient attention to drug contamination. In addition, the prescription that may be contaminated with the drug as described above is, for example, checked by the operator and checked by the inspector and printed by the operator. Further, the prescription is transported to a storage location by an office worker or the like and stored. Accordingly, there is a possibility that the inspector or the office worker may be exposed to the medicine through the prescription, and the contaminated prescription is stored as it is for a predetermined period, which becomes a secondary cause of the contamination of the medicine.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a safety cabinet and a dispensing system capable of improving workability in dispensing work using a safety cabinet and preventing chemical contamination due to a prescription. Yes.

  In order to achieve the above-mentioned object, a safety cabinet according to the present invention includes a suction means for sucking out air in an internal work space to make the inside a negative pressure, and an operator for putting the hand in the work space to work. An opening, a screen arranged toward a worker in the work space, and a projector that projects an image on the screen are provided.

  According to such a configuration, when the work in the safety cabinet is performed according to a document such as some instructions, the data such as the image of the document projected on the screen provided in the work space in the safety cabinet is viewed. It becomes possible to work while. In this case, since the screen is in the work space where the operator works, there is no significant movement between the line of sight when working and the line of sight when looking at the screen, and work according to the instructions efficiently projected on the screen. Can be performed. In other words, it is not necessary to shift the line of sight from the work space to the front of the work space, as in the case where the document is secured to the frame of the safety cabinet with a magnet. It will not be difficult. Accordingly, it is possible to see the information projected on the screen with little movement of the line of sight of looking at one's hand during work. Accordingly, it is possible to repeatedly perform work and confirmation of instructions without moving the line of sight much, and it is possible to improve work efficiency and work accuracy. That is, it is difficult to make mistakes because the instructions can be confirmed immediately during the work. Thereby, this invention can aim at the improvement of work efficiency and the improvement of work precision also in the dispensing operation | work which looks at a prescription.

In the configuration of the present invention, it is preferable that prescription data for dispensing is input from the outside of the projector, and the projector projects the prescription data on the screen.
According to such a configuration, it is possible to improve the efficiency of the dispensing work while looking at the prescription.

Moreover, in the said structure of this invention, a processing apparatus is provided,
Prescription storage means for storing the prescription data output to the projector to the processing device, and a prescription for projecting the prescription data on the screen by outputting the prescription data from the prescription storage means to the projector Output means;
It is preferable to provide worker input means that enables the worker to input data.

  According to such a configuration, since prescription data input from the outside is displayed on the screen, the safety cabinet does not require, for example, a prescription made of a paper medium, and an operator does not touch the prescription. Therefore, it is possible to prevent spread of drug contamination due to the prescription touched by the operator. Furthermore, since the prescription is not contaminated with high-risk drugs, the safety of people who come into contact with the prescription can be improved. In addition, when a sign or seal indicating that dispensing has been performed in accordance with the prescription is required at the time of the dispensing operation, for example, after inputting data enabling authentication etc. by the worker input means, It is possible to enter data indicating that the preparation has been made and confirmed. This data only needs to replace the seal or signature, and does not necessarily have to be evidence such as a photograph.

The dispensing system of the present invention is a dispensing system comprising the safety cabinet,
In the safety cabinet, a camera that captures the work space of the safety cabinet and outputs image data to the processing device, an external processing device disposed at a different location with respect to the safety cabinet, and the external processing device External input / output means for inputting / outputting data to / from the communication apparatus, and communication means for connecting the external processing apparatus to the processing apparatus in a communicable manner,
The prescription data input to the external processing device by the external input / output unit is transmitted from the external processing device to the processing device via the communication unit and input to the projector, and the prescription data is input to the projector. Projection onto the screen,
Image data of the work space photographed by the camera is input from the processing device to the external processing device via the communication unit, and the image data is displayed on a monitor included in the external input / output unit. To do.

  According to such a configuration, the inspector can audit the dispensing operation by a monitor at a place different from the safety cabinet, and can send the prescription data to the processing device of the safety cabinet and project it from the projector onto the screen. it can. Therefore, the auditor can be prevented from being exposed to the high risk drug. That is, the auditor can check the dispensing by the worker without being exposed to the high-risk drug.

  ADVANTAGE OF THE INVENTION According to this invention, while improving the working efficiency of the dispensing operation | work based on a prescription, it can prevent that a prescription becomes a cause of contamination of a high risk medicine.

It is the schematic which shows a dispensing system provided with the safety cabinet which concerns on this invention.

  Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the safety cabinet 1 has a work space 2 inside. The safety cabinet 1 is provided in front of the work space 2 (on the worker side), and includes an opening 3 that communicates with the work space 2, a shutter 4 that can open and close the opening 3, and the work space 2. And suction means (not shown) for sucking air (gas).

  In addition, for example, a chair 10 on which an operator sits is disposed in front of the safety cabinet 1. The work space 2 of the safety cabinet 1 has, for example, a lower floor surface, left and right inner surfaces, an upper ceiling surface, and a rear surface facing the operator in the back of the work space 2. Has a screen 12 for projecting data of the prescription 40 and the like. The screen 12 is disposed inside the work space 2 so as to face the worker and be visible to the worker. This screen 12 is basically disposed in the working space 2 at all times, has resistance to high-risk medicine decontamination agents such as ozone, and is difficult to be oxidized by ozone.

  Further, the safety cabinet 1 includes a projector 14 that projects the data of the prescription 40 and the like on the screen 12 outside the work space 2. The projector 14 is disposed at a position where an image can be projected on the screen 12, but does not have to be disposed directly in front, and may be disposed obliquely. In this case, the shape of the projected image is distorted, but is corrected by the correction function of the projector 14.

  Therefore, the projector 14 is disposed at a position that is unlikely to obstruct the operator's work and that the operator's shadow is unlikely to enter the image projection. Further, the projector is arranged so that the image projected on the shutter 4 during work is not obstructed. Even if the shutter 4 is transparent, it is preferable that the projector 14 projects an image from a portion where the shutter 4 is opened. At this time, the shutter 4 is not fully opened and is partially opened to the extent that it does not interfere with the work.

By arranging the projector 14 outside the work space 2, for example, the projector 14 can be prevented from being affected by chemicals such as ozone gas for decontamination. Further, the projector 14 can be prevented from being contaminated with high-risk medicine.
In addition, the safety cabinet 1 is provided with a camera 16 for photographing a portion of the work space 2 where the worker is working, in particular, outside the work space 2. The camera 16 photographs the dispensing operation in order for the auditor to confirm the dispensing operation and to keep a record of the dispensing operation. The operator should make the camera 16 photograph the label of the medicine container, the scale of the syringe when the medicine solution is sucked with the syringe, and the container with the medicine amount reduced or emptied. Can do. The camera 16 is disposed at a position where the worker and the shutter 4 are unlikely to obstruct the shooting of the work space 2 during shooting. By disposing the camera 16 on the outside of the work space 2, it is possible to prevent contamination by high-risk medicine and not be affected by chemicals such as ozone for decontamination. The projector 14 and the camera 16 are attached to the safety cabinet 1, but may be separated from the safety cabinet 1. However, the camera 16 and the projector 14 are connected to the processing device 20 of the safety cabinet 1 as described later.

  The safety cabinet 1 includes worker input means for an operator to perform an input operation. The worker input means also serves as worker authentication means for authenticating the worker and worker confirmation means for the worker to check the check items in the dispensing work and to input data in place of the seal or signature. The operator input means includes, for example, an operation panel 18 provided outside the work space 2 of the safety cabinet 1 and in the vicinity of the opening 3. Even if there are operation buttons, a pointing device, a keyboard, etc. Good. The operation panel 18 includes a keyboard for inputting a password for worker authentication, a biometric authentication device capable of biometric authentication such as a fingerprint, an IC cart or magnetic card carried by the worker, and an RF tag card. A card reader or the like may be provided. These cards store worker authentication data.

  The safety cabinet 1 is provided with a processing device 20 to which a projector 14, a camera 16, an operation panel 18 and the like are connected. The processing device 20 may be provided in the projector 14, the camera 16, or the operation panel 18. Further, the processing device 20 does not have to be a single unit, and may be provided in the camera 16, the projector 14, and the operation panel 18, respectively. When there are a plurality of processing devices 20, it is preferable that they are connected so as to be able to transmit and receive data.

Furthermore, a communication unit 22 is connected to the processing device 20, and an external processing device 24 described later is connected via the communication unit 22. The communication means 22 is, for example, Ethernet (registered trademark) of a local area network, but may be wired or wireless such as WiFi. The communication means 22 enables data transmission / reception between the processing device 20 and the external processing device 24.
Note that when there are a plurality of processing devices 20 as described above, the communication unit 22 may be able to transmit and receive data between the plurality of processing devices 20.

  Here, the safety cabinet 1, the camera 16, and the like are provided in the dispensing chamber 42, while the external processing device 24 is provided in a management room 44 that is a separate room from the dispensing chamber 42. . The management room 44 may be in the same building as the dispensing room 42 or in a different building. In the management room 44, an inspector's desk 32 and a chair 34 are installed, and the external processing device 24 is arranged on the desk 32. The external processing device 24 is connected to a monitor 26, a keyboard 28, an image input device 30 such as a scanner or a camera, a pointing device (not shown), etc. as external input / output means. A simple computer system.

In such a dispensing system, data of a prescription 40 for dispensing is taken in at the time of dispensing work. Here, the prescription 40 issued as a paper medium is captured by the image input device 30 such as a camera or a scanner, and patient information including the patient's name, sex, age, etc. is stored in the prescription storage area of the storage device of the external processing device 24. And stored in association with drug information such as the name of the medicine to be dispensed.
The image data of the prescription 40 is output from the external processing device 24 to the processing device 20 via the communication unit 22. In the processing device 20, the image data of the prescription 40 is stored in the storage unit as in the case of the external processing device 24. The processing device 20 outputs the image data of the prescription 40 stored in the storage means to the projector 14, and the projector 14 projects the image data of the prescription 40 on the screen 12 and displays it.

  Note that the prescription 40 is currently a paper medium, but may be electronic. The electronic prescription 40 includes data such as text and format, for example, and this data is used as text or the like. You may project on the screen 12 from the projector 14. FIG.

  Further, the image data of the work space 2 of the safety cabinet 1 photographed by the camera 16 in the dispensing chamber 42 is output to the processing device 20, and the processing device 20 uses this image data as an external processing device via the communication means 22. 24. The external processing device 24 displays this image data on the monitor 26. The inspector of the management room 44 audits the dispensing operation using the image displayed on the monitor 26.

  When the paper medium prescription 40 is used, the paper medium prescription 40 is not brought into the dispensing chamber 42 and only the data is displayed on the screen 12 of the safety cabinet 1 in the dispensing chamber 42 as described above. When dispensing ends, the operator in the dispensing room and the auditor in the management room 44 confirm that dispensing has been performed according to the prescription 40, respectively. At this time, there is a paper medium prescription 40 in the hands of the auditor, and after confirming, the auditor stamps or signs the prescription 40. It is not realistic for an operator in the dispensing room 42 to stamp or sign the prescription 40 in the management room 44. Here, for example, the authentication means provided on the operation panel 18 of the safety cabinet 1 of the dispensing chamber 42 serves as, for example, a password authentication or biometric authentication function such as a fingerprint and a confirmation means for accepting a confirmation operation by an operator. Data indicating that the dispensing based on the prescription 40 by the operator has been normally performed by the function is input to the processing device 20, and this data is transmitted to the external processing device 24 via the communication unit 22. The In the external processing device 24, printing means such as an automatic stamping device is provided in the external input / output means, and the prescription 40 is marked with an operator's mark or the like. The prescription 40 is not contaminated by the medicine and is stored, for example, in a prescription storage place.

  When the prescription 40 is electronic, the worker performs authentication and confirmation as described above in the safety cabinet 1 and stores them in the processing device 20 for successful dispensing. Then, the inspector performs authentication and confirmation in the external processing device 24 of the management room 44 in the same manner as the worker, and these are stored in the external processing device 24. These data are stored and stored in some kind of storage.

  In such a dispensing system having the safety cabinet 1, when the paper medium prescription 40 is used, the prescription 40 is audited in the management room 44 without being brought into the dispensing room 42 where the safety cabinet 1 where the dispensing is performed. It is in a state where it is handled by a person. The image data of the prescription 40 is read by the image input device 30 and input to the external processing device 24, the image data of the prescription 40 is transmitted to the processing device 20, and this image data is output from the processing device 20 to the projector 14. Projected onto the screen 12.

  In this state, the operator can dispense while looking at the prescription 40 projected on the screen 12. In this case, the screen 12 is inside the work space 2 of the safety cabinet 1, and a certain amount of longitudinal distance can be secured between the screen 12 and the worker. In other words, conventionally, the paper medium prescription 40 fastened to the frame of the safety cabinet 1 is arranged at the position of the front surface of the shutter 4 of the safety cabinet 1 (outside the work space 2). The front-rear distance with the worker sitting close to the head cannot be secured, and the prescription 40 is difficult to see.

  In the present embodiment, the worker often adjusts his / her line of sight to his / her hand placed in the work space 2 during the work, but the screen 12 is disposed, for example, on the back side in the work space 2. In addition to having an appropriate longitudinal distance between the operator and the operator, the user can see his hand and the screen 12 without moving his line of sight. Therefore, it is possible to work in a state in which the description of the prescription 40 is compared with the dispensing work performed by one's hand, so that the work can be performed efficiently and the prescription 40 can be confirmed. During the work, it is less likely that the eyes are removed from the work, and troubles caused by taking the eyes away from the work can be avoided. Moreover, when the prescription 40 is displayed using the monitor in the work space 2, the monitor is exposed to the high-risk medicine. Therefore, if the monitor is taken out of the work space 2 in the event of a failure of the monitor, the high-risk medicine is taken out of the safety cabinet 1. In particular, various devices are arranged in the housing of the monitor, and it is difficult to decontaminate the inside of the monitor and take it out of the safety cabinet 1. On the other hand, in this embodiment, the projector 14 is outside the work space 2 and can be prevented from being contaminated with high-risk medicine. The screen 12 can be basically a sheet-like or plate-like one, and can be decontaminated with ozone if there is no problem of oxidation or the like in terms of material. It is also possible to use a material that does not soak high-risk medicine into the screen 12. The screen 12 may be the rear surface of the work space 2 of the safety cabinet 1, or the rear surface may be coated with the screen 12.

  In the dispensing operation, the operator does not put the paper-based prescription 40 into or into the work space 2 of the safety cabinet 1, and further, the operator does not touch the prescription 40 with the hand that performed the dispensing operation. The prescription 40 can be prevented from being exposed to the high-risk medicine through the prescription 40 without being contaminated with the high-risk medicine.

  The auditor can audit the dispensing operation while in the management room 44, which is a room different from the dispensing room 42 in which the safety cabinet 1 is arranged. In the dispensing room, the auditor can be prevented from being exposed to the drug.

  As described above, it is possible to avoid the risk that an auditor other than the worker who actually performs the dispensing work will be exposed to the high-risk medicine, and the worker can more easily see the prescription 40 than in the past. This makes it easier to concentrate on the work. Thereby, the risk in handling high-risk medicine can be reduced. As described above, the prescription 40 is not limited to a paper medium, and may be an electronic one. In this case, authentication and confirmation can be performed digitally, and a seal or signature is not necessarily required. Even when the paper-based prescription 40 is not used, the prescription 40 is displayed on the screen and the operator does not touch the prescription 40 as in the case where the paper-based prescription 40 is used. The same operational effects as in the case of a paper medium can be obtained.
