BACKGROUND OF THE INVENTION
  The present invention is a cleaning path that allows cleaning objects such as instruments, containers, and materials to be carried into a cleaning space for cleaning, and maintained in a sterile (dust-free) state to be transferred to the working space and handled. Clean bench device with a box, clean bench device with a cleaning pass box that can be operated by selectively switching the atmospheric pressure of the work space between positive pressure, normal pressure and negative pressureIn placeRelated.
[0002]
[Prior art]
  Conventionally, in the medical field, when performing dispensing operations such as injectable drug mixing at pharmacies and wards, a clean bench is installed, and the air in the clean bench is cleaned (sterilized) in a working space ( It is desirable to perform dispensing operations by handling disinfected (eg, syringes), containers (eg, ampoules, vials, infusion bags, etc.) and drugs. Some pharmacies and wards have a clean room in which the internal air is purified, and in such clean rooms, dispensing work such as mixed injections is performed without using a clean bench.
[0003]
  For objects to be cleaned such as instruments and containers that are carried into the work space in the clean bench, use the cleaning pass box to clean the objects to be cleaned, then remove the objects to be cleaned from the cleaning pass box and transport them to the clean bench. It will be brought in. However, in order to maintain the objects to be cleaned that have been cleaned during the transfer in a sterile (dust-free) state, a clean room is provided, a cleaning pass box is installed at the entrance of the clean room, and a clean bench is installed in the clean room. Equipment is required. In addition, when handling chemicals that do not cause so-called chemical hazards, it is possible to perform a dispensing operation such as a mixed injection without using a clean bench in a clean room.
[0004]
  A typical clean bench is a work table, a case that covers the work space above the work table, a work opening formed in the case, a shutter that opens and closes the work opening, a ventilator that ventilates the air in the work space, and a ventilator It is equipped with a filter that cleans the air ventilated in the room, and with the shutter open and the work opening open, the operator can put his hands into the work space from the work opening and handle the instruments and containers etc. (For example, refer to Patent Document 1).
[0005]
  As this type of clean bench, one that operates with the atmospheric pressure in the work space being positive and one that operates with the atmospheric pressure in the work space as negative pressure have been put into practical use. A clean bench that can be operated accordingly is used. In particular, when handling dangerous drugs (eg anticancer agents) that may cause chemical hazards in the work space, the atmospheric pressure in the work space should be negative so that the air in the work space does not flow directly out of the work opening. A clean bench is used.
[0006]
  By the way, a clean bench is known that can be switched by an operator's switch operation to either a positive pressure operation mode that operates with a positive atmospheric pressure in the work space or a negative pressure operation mode that operates with a negative pressure (for example, , See Patent Document 2).
  This clean bench is basically equipped with the same work table, case, work opening, shutter, ventilator, filter, etc. as a general clean bench. As the ventilator, an electric fan, intake and exhaust ports, intake air An intake damper that opens and closes the passage and an exhaust damper that opens and closes the exhaust passage are provided, and the operation mode is switched by switching between the opening and closing states of the intake damper and the exhaust damper.
[0007]
  On the other hand, as a pass box, it is installed at the entrance of a clean room and includes a case for storing an object to be cleaned, an electric fan and a filter provided in the case, and the air cleaned by the filter is circulated in the case by the electric fan. What is supplied is known (for example, see Patent Document 3).

[Problems to be solved by the invention]
  The conventional clean bench including the clean bench described in Patent Documents 1 and 2 does not have a function of cleaning an object to be cleaned such as an instrument or a container. Therefore, the object to be cleaned is cleaned using a cleaning pass box. After that, the object to be cleaned is taken out from the cleaning pass box, transported to the clean bench, and carried into the work space. During the transport, a clean room is provided to maintain the cleaned object to be aseptic, A cleaning pass box must be installed at the entrance of the clean room, and a clean bench must be installed in the clean room.
[0010]
  In other words, a large space is required to provide a clean room in a pharmacy, ward, etc., and a large-scale air purification facility is required, and a dedicated entrance is formed on the wall of the clean room, and a cleaning pass is provided at the entrance. Since the box must be installed, the equipment cost becomes very expensive. It should be noted that there is a limit to reducing the distance between the cleaning pass box and the clean bench, and the load for transferring the object to be cleaned from the cleaning pass box to the clean bench increases accordingly.
[0011]
  In addition, the conventional clean bench has been put into practical use, one that operates with the atmospheric pressure in the work space positive, and the other that operates with the atmospheric pressure in the work space as negative pressure. Since the working atmosphere can be operated only with either positive or negative pressure, two types of clean benches are required when both positive and negative pressure are required. It is also necessary to secure an installation space for two clean benches, resulting in high equipment costs.
[0012]
  As in Patent Document 2, a clean bench is known that can be switched between a positive pressure operation mode that operates with a positive atmospheric pressure in the work space and a negative pressure operation mode that operates with a negative pressure. The operation mode is switched by the operator's switch operation. Therefore, there is a possibility that the dispensing operation may be performed by operating the switch in an unplanned operation mode by mistake. In particular, when handling powerful drugs, etc., if the dispensing operation is performed by operating in the positive pressure operation mode, the air in the working space may flow directly out of the work opening and cause chemical hazards. .
[0013]
  Also, with this clean bench, it is not possible to switch to a mode that operates at atmospheric pressure in the work space, so there is a risk that the optimal operation mode cannot be set according to the chemicals handled in the work space. In that respect, it is inferior in versatility.
  In the pass box as in Patent Document 3, since only one electric fan is provided, there is a limit in improving the air ventilation performance. Although it is conceivable to install an electric fan dedicated to intake and an electric fan dedicated to exhaust, if an electric fan dedicated to intake and an electric fan dedicated to exhaust are also installed on the clean bench, the number of actuators will increase as a whole and the equipment will become larger It becomes disadvantageous in cost.
[0014]
  The object of the present invention is to clean the object to be cleaned, such as instruments, containers and materials, without providing a clean room, and then maintain the object to be cleaned in a sterilized state easily and reliably in the work space in the clean bench. Information on the types of chemicals and substances that can be carried in, the clean bench operation mode can be switched selectively to either positive pressure, normal pressure or negative pressure operation mode, and the switching is handled in the work space. Automatically based on the above.

[0071]
  Next, control including cleaning mode switching control, manual automatic switching control, and operation mode switching control executed by the control unit 62 of the clean bench apparatus 1 will be described based on the flowchart of FIG. In the flowchart, Si (i = 1, 2, 3,...) Indicates each step. This control is started when the power of the clean bench device 1 is turned on and is finished when the power is turned off.
[0072]
  When this control is started, first, various initial settings (S1) are executed. In this initial setting, in particular, the air cleaning mode is set as the cleaning mode of the cleaning pass box 2, the manual switching state is set as the operation mode switching state of the clean bench 3, and the positive pressure operation mode is set as the mode for operating the clean bench 3. Is set. If each mode is not changed after the power is turned on, the cleaning pass box 2 is operated in the air cleaning mode, and the clean bench 3 is operated in the positive pressure operation mode.
[0073]
  Next, when there is an operation of the cleaning mode changeover switch 66 (S2; Yes), the cleaning mode of the cleaning pass box 2 is selectively switched to either the air cleaning mode or the cleaning liquid cleaning mode in accordance with the operation (S2; Yes). S3). After S3 or when the cleaning mode changeover switch 66 is not operated (S2; No), it is determined whether or not the manual automatic changeover switch 67 is operated (S4). Therefore, when the manual automatic switch 67 is operated (S4; Yes), the mode switching state of the clean bench 3 is switched to the manual mode switching state or the automatic mode switching state according to the operation (S5).
[0074]
  After this S5, or when there is no operation of the manual automatic changeover switch 67 (S4; No), when it is in the manual mode changeover state (S6; Yes), whether or not the operation mode changeover switch 68 is operated. Is determined (S7). Therefore, when the operation mode changeover switch 68 is operated (S7; Yes), the operation mode of the clean bench 3 is selected from the positive pressure operation mode, the normal pressure operation mode, and the negative pressure operation mode according to the operation. Switching is made uniformly (S8). After S8 or when the operation mode changeover switch 68 is not operated (S7; No), the process returns to S2.
[0075]
  On the other hand, if it is not the manual mode switching state (S6; No), it is determined whether or not it is the automatic mode switching state (S9). Therefore, if it is not the automatic mode switching state (S9; No), it is determined that the initial setting, mode switching or the like has not been performed normally, and the process returns to S1 and various initial settings are executed again.
[0076]
  If it is in the automatic mode switching state (S9; Yes), it is determined whether or not there is information on the type of medicine or substance that is read by the barcode reader 65 and handled in the current work space 31 (S10). In this case (S10; Yes), the operation mode of the clean bench 3 is automatically selected from the positive pressure operation mode, the normal pressure operation mode, and the negative pressure operation mode based on the information on the type of the medicine or substance. (S11).
[0077]
  Note that the operation panel 61, the control unit 62, and the drive unit 62 correspond to operation mode switching means for selectively switching between the positive pressure operation mode, the negative pressure operation mode, and the normal pressure operation mode via the ventilation device 35. In addition, automatic mode switching means for automatically switching the operation mode based on information on the types of drugs and substances handled in the work space 31 and manual mode switching means for switching the operation mode by an operator's manual operation are included.
[0078]
  Here, information on the types of drugs and substances handled in the work space 31 and the technology for automatically switching the operation mode of the clean bench 3 based on the types of the drugs and substances will be described in detail with an example.
[0079]
  First, as shown in FIG. 9, various drugs (and substances) handled in the work space 31 are classified in advance into three types, group A, group B, and group C. For example, Group A drugs (and substances) include various drugs other than anti-cancer drugs that need to be handled while maintaining aseptic conditions as much as possible. Various drugs other than anti-cancer drugs that are desirable to be maintained and handled and are not injected directly into the body are included. Group C drugs and substances include chemical hazards such as powerful drugs that contain anti-cancer drugs. Contains various drugs that may be of concern.
[0080]
  The ROM of the control unit 62 stores in advance a determination table for determining the type of drug or substance (group A, B or C) input from the barcode reader 65, and collates the determination table with the input information. Then, a group of drugs and substances handled in the work space is determined. By the way, when two or more types of drugs and substances (for example, group B drugs and group C drugs) are handled in the work space 31 at a time, it has the advantage of increasing in the order of group A → B → C and is the highest. A group including drugs and substances having superiority is determined as a group of drugs and substances handled in the work space 31.
[0081]
  When the determined group is A, the mode is automatically switched to the positive pressure operation mode. In the case of B, the mode is automatically switched to the normal pressure operation mode. It can be switched automatically.
[0082]
  The operation and effect of the clean bench device 1 will be described.
  According to the clean bench apparatus 1, the cleaning pass box 2 is integrally provided adjacent to the clean bench 3, and the cleaning pass box 2 is provided on the partition wall 38 that partitions the cleaning pass box 2 and the clean bench 3. Since the loading opening 57 is formed so as to face the cleaning space 11 inside and the work space 31 inside the clean bench 3, the opening / closing door 58 that opens and closes the loading opening 57 is opened and the loading opening 57 is opened. The object to be cleaned that has been cleaned in the cleaning space 11 can be easily and reliably carried into the work space 31 in the clean bench 3 from the loading opening 57 while being maintained in a sterile (dust-free) state.
[0083]
  As a result, there is no need for a clean room, which was previously required for transporting cleaned objects to be cleaned from a cleaning pass box to a clean bench, which saves space in pharmacies and wards. This makes it possible to significantly reduce equipment costs.
[0084]
  Since the operation mode of the clean bench 3 can be selectively switched to any one of the positive pressure operation mode, the normal pressure operation mode, and the negative pressure operation mode via the ventilation device 35, It can be operated in an optimal operation mode according to the type of substance. And since the some clean bench from which an operation mode differs is not required, installation cost can be reduced significantly.
[0085]
  The ventilation device 35 includes the electric fan 40, the intake port 41 and the exhaust port 42, the first damper 44 that can open and close the intake passage 43, and the second damper 46 that can open and close the exhaust passage 45. By switching the open / close state of the first damper 44 and the open / close state of the second damper 46, the operation mode of the clean bench 3 can be easily switched to any of the positive pressure operation mode, the normal pressure operation mode, and the negative pressure operation mode. .
[0086]
  Since the operation mode of the clean bench 3 is automatically switched based on the information on the types of drugs and substances handled in the work space 31, the optimum operation mode is surely determined according to the types of drugs and substances handled in the work space 31. In particular, when handling a powerful drug in the work space 31, it is possible to switch to the negative pressure operation mode to reliably deal with chemical hazards.
[0087]
  Since the operation mode of the clean bench 3 can be switched by an operator's manual operation, the operation mode can be switched effectively depending on the types of chemicals and substances handled in the work space 31, and automatic switching is supported. It is also possible to handle drugs (new drugs, etc.) and substances that cannot be handled in the work space.
[0088]
  Since the intake fan 24 and the exhaust fan 26 are provided in the cleaning pass box 2, the air ventilation performance can be improved, and the exhaust fan 26 of the cleaning pass box 2 is operated in the negative pressure operation mode of the clean bench 3. Since the air in the work space 31 in the clean bench 3 is exhausted from the exhaust port of the cleaning pass box 2 to the outside through the exhaust communication port 55, the exhaust fan 26 of the cleaning pass box 2 is effectively used to clean the air. The atmospheric pressure in the work space 31 in the bench 3 can be reliably set to a negative pressure, which is advantageous in terms of production cost.
[0089]
  In the cleaning pass box 2, it is possible to selectively switch between an air cleaning mode for cleaning an object to be cleaned with air and a cleaning liquid cleaning mode for cleaning an object to be cleaned with a cleaning liquid. The object can be cleaned with air, or the object to be cleaned can be cleaned with a cleaning liquid.
[0090]
