However, by providing the sterilization processing number processing unit, according to the sterilization processing conditions, since it can be converted into the sterilization processing number based on the reference sterilization processing number, the sterilization conditions are different. In addition, the number of times that the dental treatment tool has been sterilized can be calculated. Thereby, for example, by comparing and determining the limit number of times of sterilization treatment of the dental instrument previously stored in the identification information and the cumulative number of sterilization processes, it is possible to inform the necessity of replacement of the dental instrument, The practitioner can grasp the replacement time of the dental treatment tool.

  Thus, even when sterilized under various sterilization conditions, it is possible to determine the replacement timing of the dental surgical instrument based on a predetermined standard. For example, the dental surgical instrument is recommended by a contractor. Even when the sterilization process takes longer than the sterilization conditions to be performed, the practitioner can accurately grasp the replacement time of the dental instrument, and the sterilization apparatus is close to the replacement time. It can be replaced in advance with a dental instrument that can be safely operated.

Further, as an aspect of the present invention, the sterilization processing determination unit can determine whether the sterilization processing is performed or the sterilization processing is performed by comparing the sterilization processing timing with the use timing of the dental treatment tool.

The patient's treatment using the medical treatment apparatus 1 having such a configuration will be described based on the flowchart shown in FIG.
As preparation for the treatment, the medical diagnostic apparatus 1 is turned on, and patient information of a patient to be examined first is read and displayed on the monitor 15. When the first patient sits on the medical chair 71, the weight change on the medical chair 71 is measured by the weight sensor 71a under the control of the patient change detection unit 11h.

  The practitioner takes out the sterilized handpiece 30 from the sterilization bag in front of the patient sitting on the medical chair 71 and brings the handpiece 30 close to the connection unit 40. Thereby, the medical device main body 10 can detect the handpiece 30 (step s1).

  More specifically, the practitioner brings the handpiece side connection portion 34 closer to the unit side connection portion 43 in order to connect the handpiece 30 and the connection unit 40. Thus, the signal from the RFID tag 50 provided on the handpiece 30 is received by the RFID reader / writer 60 provided on the connection unit 40, and the signal from the RFID tag 50 is received from the RFID reader / writer 60 to the RFID tag 50. A transmission command such as an identification signal is issued.

  In response to this transmission command, the reading control unit 51c stores identification information L stored in the identification information storage unit 52a, sterilization processing information O stored in the sterilization processing information storage unit 52b, and usage stored in the use detection information storage unit 52c. Read control with the detection information U is performed. Then, identification information L, sterilization processing information O, and use detection information U are transmitted from the communication antenna 53 toward the RW communication antenna 61 under the control of the communication control unit 51d. Based on the fact that the RFID reader / writer 60 has received the identification information L, it is determined whether the handpiece 30 can be driven and controlled by the medical device body 10.

Here, the process of determining whether the handpiece 30 can be driven by the medical device main body 10 will be briefly described with reference to FIGS. 7 and 8.
When the connection unit 40 receives the identification information L transmitted from the handpiece 30 (step t1), the handpiece information I stored in the handpiece information storage unit 12a is read under the control of the information reading control unit 11c. Then, the handpiece 30 determines that the serial number of the identification information L and the serial number stored in the handpiece information I are collated by the handpiece identification determination unit 11a to find out whether there is a match. 10 determines whether it can be driven (step t2).

  If it is determined that the handpiece 30 can be driven by the medical device main body 10 as a result of the determination by the handpiece identification determination unit 11a (step t2: Yes), the handpiece identification determination is performed by the control of the main body side communication control unit 11b. The determination result determined by the unit 11a is transmitted to the handpiece 30 (step t3A).

  By receiving the determination result determined by the handpiece identification determination unit 11a (step t3B), the HP notification operation control unit 51f lights the handpiece side notification unit 33 in blue based on the determination result (step t4). ) End the connection determination step. Thereby, without connecting the handpiece 30 and the connection unit 40, the practitioner can know that the handpiece 30 can be connected to the medical device main body 10 and driven and controlled.

  On the other hand, when it is determined by the determination process of the handpiece identification determination unit 11a that the handpiece 30 cannot be driven by the medical device main body 10 (step t2: No), the handpiece is connected via the RW communication antenna 61. The determination result of the identification determination unit 11a is transmitted to the communication antenna 53 (step t5A). Then, based on the reception of the determination result by the communication antenna 53 (step t5B), the handpiece-side notification unit 33 is lit in orange under the control of the HP notification operation control unit 51f (step t6).

  Accordingly, it is understood that the practitioner cannot drive and control the handpiece 30 with the medical device main body 10 without connecting the handpiece 30 and the connection unit 40. Therefore, the connection operation between the handpiece 30 and the connection unit 40 can be stopped, or the practitioner connects the handpiece 30 to the medical device main body 10 by calling the driving condition of the handpiece 30 from, for example, the network. Drive control.

Next, the sterilization processing information O transmitted from the RFID tag 50 and the use detection information U are compared and determined to determine whether the handpiece 30 can be used (step s2).
The determination as to whether or not the handpiece 30 can be used is performed by reading information on whether or not the handpiece 30 has been sterilized from the sterilization processing information O and identifying the state of the handpiece 30 and detecting the use. The end time of use (or time of disconnection) immediately before storing in the information U is compared with the time for performing the sterilization processing stored in the sterilization processing information O, and the sterilization processing is performed after the handpiece 30 is used. And a usability determination step for determining whether or not.

  Specifically, in the sterilization information reading process, under the control of the sterilization process determination unit 11d, the “sterilization process” that is the content of the sterilization process item corresponding to the earliest sterilization process time described in the sterilization process information O is read. , Identifying that the handpiece 30 has been sterilized.

In the next use availability determination step, the latest use end time stored in the use detection information U is compared with the latest sterilization end time stored in the sterilization processing information O under the control of the use determination unit 11e. Determine.
Specifically, under the control of the use determination unit 11e, the latest use end time (14:52 on January 10, 2015) stored in the use detection information U and the latest use stored in the sterilization information O are stored. The sterilization end time (January 10, 2015, 16:52) is read and compared, and it is determined that the handpiece 30 has been sterilized after use (step s2: Yes).

  Along with this determination result (step s2: Yes), the notification program stored in the notification setting storage unit 12d is read under the control of the main body side notification operation processing unit 11g, and the notification program is executed. As a result, “use of the handpiece” is displayed on the main body side notification monitor 17c and the monitor 15, and the HP notification operation control unit 51f based on the determination result being transmitted to the handpiece 30 controls the handpiece side. The notification unit 33 is lit in green. Thereby, the practitioner can recognize that the handpiece 30 has been sterilized, and the handpiece 30 can be connected to the connection unit 40.

In this embodiment, identification of the sterilization state of the handpiece 30 and determination of whether or not sterilization processing has been performed after use of the handpiece 30 are performed in this order. The determination as to whether or not sterilization has been completed after use may be made first.
In addition, when it is determined that the sterilization process has not been performed by the determination of the sterilization process, only the determination of the sterilization process can be performed. This eliminates unnecessary processing and reduces the load on the CPU.

  When the practitioner connects the handpiece 30 and the connection unit 40, the connection between the handpiece 30 and the connection unit 40 is determined from the information obtained from the proximity detection sensor 435 provided in the connection unit 40 under the control of the connection determination unit 11i. While detecting (step s3), the drive condition suitable for the handpiece 30 is read from the exchange reference | standard information storage part 12c based on the serial number of the identification information L of the connected handpiece 30 by control of the drive control part 11f (step S3). Step s4).

  As a result, a drive signal corresponding to the amount of depression of the pedal 74a provided in the chair unit 70 is controlled in accordance with the read drive conditions, and is supplied to the handpiece 30 via the drive power supply lead wire built in the connection tube 42. The cutting tool 5 transmitted and attached to the tip of the handpiece 30 rotates (step t5). Thereby, the practitioner can perform a desired treatment on the patient.

  In addition, the treatment detection unit 51g that has received the drive signal based on the depression operation of depressing the pedal 74a performs control to transmit a reading command for reading time from the time measuring unit 55 to the communication control unit 51d. When the RFID reader / writer 60 receives the reading command, the time reading unit 51b and the information update control unit 51e record the driving time read from the time measuring unit 55 in the usage detection information U, and update the usage detection information U sequentially. (Step s6). The use detection information U is updated during the treatment (step s7: No).

  When the practitioner completes the desired treatment for the patient and the practitioner removes his / her foot from the pedal 74a (step s7: Yes), the treatment detection unit 51g detects that the drive signal has been stopped for a predetermined time, and the drive signal Is recorded as the treatment end time in the use detection information U.

  When the patient who has finished the treatment descends from the medical chair 71, it is recognized that the patient has descended from the mass change of the weight sensor 71a measured by the control of the medical device main body 10h (step s8: Yes). Thereafter, when the patient who is the target of the next operation is not seated on the medical chair 71 and the power to the medical device body 10 is turned off (step s9: Yes), the operation is completed. In addition, when the power supply of the medical device main body 10 cannot be turned off (step s9: No), it is continuously detected whether the patient has been changed by the control of the medical device main body 10h (step s8: No).

  On the other hand, when the next patient is seated on the medical chair 71, it is recognized that the next patient is seated on the medical chair 71 due to the mass change of the weight sensor 71a measured by the control of the medical device body 10h (step s8: Yes), the information obtained from the proximity detection sensor 435 is analyzed to detect whether the handpiece 30 is connected to a plurality of connection units 40 (step s10).

  In the present embodiment, the change of the patient is detected when the next patient is seated. However, the change of the patient may be detected when the patient who has finished the treatment has descended from the medical chair 71.

  When the handpiece 30 is not connected to the connection unit 40 (step s10: No), the handpiece 30 that has been sterilized in front of the patient sitting on the medical chair 71 is taken out of the sterilization bag, and the handpiece 30 is removed. Is brought close to the connection unit 40, and the medical device main body 10 detects the handpiece 30 (step s1).

  On the other hand, when the handpiece 30 is connected to any one of the connection units 40 (step s10: Yes), the sterilization time of the handpiece 30 connected to the connection unit 40 And use time are compared and determined by the control of the use determination unit 11e to determine whether sterilization has been completed (step s11).

  That is, when the handpiece 30 connected to the connection unit 40 is not used for the previous patient's treatment, it is determined that the handpiece 30 has been sterilized by the use determination unit 11e (step s11: Yes). ), The driving conditions of the handpiece 30 connected to the connection unit 40 can be read and used for treatment (step s4).

  Moreover, when it determines with the handpiece 30 which is going to connect to the connection unit 40 being unsterilized (step s2: No), the handpiece 30 connected to the connection unit 40 is used for the previous patient. If it is determined that the sterilization is not yet processed (step s11: No), the drive signal to the handpiece 30 is electrically cut off by the control of the drive control unit 11f (step s12).

  Further, under the control of the main body side notification operation processing unit 11g, the holder light output unit 17a is lit red and a buzzer is emitted from the main body side audio output unit 17b. Further, information indicating that the handpiece 30 cannot be used is displayed on the main body side notification monitor 17c or the monitor 15 (step s13).

  Furthermore, the determination results of the sterilization processing determination unit 11d and the use determination unit 11e are transmitted to the communication antenna 53 via the RW communication antenna 61, and the HP notification operation control unit 51f that receives this determination result controls the handpiece side. The notification unit 33 is lit red (step s13).

  By these operations, the practitioner can grasp that the handpiece 30 connected to the connection unit 40 or to be connected has not been sterilized since the previous use, and the patient has not been sterilized. It is possible to reliably prevent the handpiece 30 from being used.

  In the blocking and notification operations of these drive signals, the medical device body 10 detects the connection state between the connection unit 40 and the handpiece 30 by analyzing information obtained from the proximity detection sensor 435 under the control of the connection determination unit 11i. If the connection unit 40 and the handpiece 30 are still connected (step s14: No), the notification operation is repeated (step s13).

  In a state where such a drive signal is cut off, it is detected by the control of the connection determination unit 11i that the handpiece 30 and the connection unit 40 have been removed based on information from the approach detection sensor 435 (step S1). s14: Yes), the interruption of the drive signal to the handpiece 30 is released by the control of the drive control unit 11f. Therefore, when the practitioner connects the sterilized handpiece 30 to the connection unit 40 (step s3), the sterilized handpiece 30 can be driven and controlled by the medical device body 10 (step s5). ).

  When it is determined that the handpiece 30 to be connected to the connection unit 40 has not been sterilized (step s2: No), the handpiece-side connecting portion 34 is moved back and forth along the longitudinal direction of the handpiece 30. By providing a protrusion mechanism 35 that moves the cylindrical body (see FIG. 2), the connection between the handpiece 30 and the connection unit 40 can be reliably prevented.

More specifically, when it is determined by the determination processing of the sterilization processing determination unit 11d and the use determination unit 11e that the handpiece 30 cannot be used for treatment (step s2: No), the communication antenna 53 receives the determination result. Based on the above, the protrusion control unit 51i performs control to cause the protrusion mechanism 35 to protrude rearward (step s12). Thereby, when it is going to connect the handpiece side connection part 34 and the unit side connection part 43, connection can be obstructed by the protrusion mechanism 35, and the connection of the handpiece 30 and the connection unit 40 can be controlled. .
Note that the use control of the handpiece 30 by the drive control by the drive control unit 11f and the protrusion of the protrusion mechanism 35 can be released by sterilizing the handpiece 30 with an autoclave.

Further, since the RFID tag 50 provided in the handpiece 30 includes the heat-resistant battery 54, the handpiece 30 can be autoclaved alone.
When the handpiece 30 is sterilized by an autoclave, the sterilization processing integration number is calculated and stored in the sterilization processing number storage unit 52d under the control of the information update control unit 51e and the sterilization processing number calculation unit 51h.

The accumulated number of sterilization treatments stored in the sterilization treatment number storage unit 52d can be used as a basis for determining whether to replace the handpiece 30.
More specifically, under the control of the replacement determination unit 11k, the handpiece 30 is determined by comparing the sterilization processing limit number stored in the replacement reference information storage unit 12c with the sterilization processing integration number stored in the sterilization processing number storage unit 52d. Processing for determining whether or not to replace is performed.

  If it is determined that the handpiece 30 needs to be replaced, the drive signal of the handpiece 30 is electrically interrupted by the control of the drive control unit 11f and the control of the main body side notification operation processing unit 11g. The holder light output unit 17a blinks yellow and a warning sound is emitted from the main body side audio output unit 17b. Further, information indicating that the handpiece 30 should be replaced is displayed on the main body side notification monitor 17c or the monitor 15.

  Thereby, the practitioner can recognize that the number of sterilization treatments of the handpiece 30 has exceeded the sterilization treatment limit number. Further, by using a different warning from that when the handpiece 30 is not sterilized after use, that is, by changing the lighting pattern of the holder light output unit 17a and the warning sound pattern from the main body side audio output unit 17b, It can be appreciated that 30 is not sterilized and needs to be replaced.

  The medical diagnostic apparatus 1 having such a configuration is detachably connectable to the handpiece 30 having the identification information storage unit 52a that stores the unique identification information L of the handpiece 30, and is identifiable. 52e for storing the sterilization processing information O related to the sterilization processing of the handpiece 30 and the change of the patient to be treated is detected. A sterilization process determination unit 11d that reads the sterilization process information O of the handpiece 30 and determines whether the sterilization process has been performed or not yet sterilized based on the patient shift detection unit 11h, and the change detection by the patient change detection unit 11h, and a sterilization process determination With the use restriction unit for restricting the use of the handpiece 30 based on the result of the sterilization unprocessed determination by the part 11d It is possible to prevent the handpiece 30 of the sterilization unprocessed used for post-reversal patients with the following patients replacement.

  More specifically, by providing the patient change detection unit 11h and the sterilization determination unit 11d, it is possible to detect that the patient has changed, and the handpiece 30 connected to the medical device main body 10 when the patient is changed is sterilized. It can be determined whether it has been treated or unsterilized. Since the drive signal is stopped by the control of the drive control unit 11f based on the determination result and the use of the untreated sterilized handpiece 30 for the patient after the change can be restricted, the practitioner can only use the sterilized handpiece 30. Can be used for treatment.

  Further, the handpiece 30 includes an RFID tag 50 including an identification information storage unit 52a, and the RFID reader / writer 60 reads the identification information L from the adjacent RFID tag 50 in a non-contact manner, whereby the medical device main body. When the handpiece 30 scheduled to be connected to 10 has not been sterilized, the sterilization state can be determined without bringing the medical device body 10 and the handpiece 30 into contact with each other. Therefore, it is possible to prevent the medical device body 10 from being contaminated.

  Specifically, the RFID reader / writer 60 is provided in the medical device main body 10 and the RFID tag 50 is provided in the handpiece 30, so that the medical device main body 10 reads the identification information L without contacting the handpiece 30. Can do. Therefore, under the control of the information reading control unit 11c and the sterilization processing determination unit 11d provided in the medical device main body 10, the medical device main body 10 does not contact the handpiece 30 and sterilization processing information O corresponding to the identification information L is obtained. Can be determined whether the handpiece 30 has been sterilized or not yet sterilized.

  As described above, since it is not necessary to bring the handpiece 30 and the medical device main body 10 into contact for the determination of the sterilization treatment, the handpiece 30 to be connected to the medical device main body 10 has not been sterilized. However, it is possible to prevent the handpiece 30 from being connected to the medical device main body 10 and to prevent the medical device main body 10 from being contaminated.

  In addition, the drive control unit 11f is characterized by prohibiting the operation of the handpiece 30 by blocking the drive signal sent from the medical device body 10 to the handpiece 30. When it is determined that the process is to be performed, the drive signal from the medical device main body 10 to the handpiece 30 is not transmitted, and the driving of the handpiece 30 is restricted. Therefore, it is possible to prevent the practitioner from performing an operation using the handpiece 30 used for another patient by mistake.

  The medical device main body 10 is provided with a unit side connection portion 43, and the handpiece 30 is provided with a handpiece side connection portion 34 connected to the unit side connection portion 43, and at least one of the medical device main body 10 is provided with a unit. The protrusion mechanism 35 which forms the connection prevention shape which prevents the connection of the side connection part 43 and the handpiece side connection part 34 can be provided. Thereby, when it is going to connect the sterilization-untreated handpiece 30 and the medical device main body 10, the handpiece 30 and the medical device are formed by the protruding mechanism 35 that forms a connection prevention shape based on the sterilization processing information O. The connection with the main body 10 can be prevented, and the physical connection between the handpiece side connection portion 34 and the unit side connection portion 43 can be reliably prevented.

  Thus, by providing the protrusion mechanism 35, the practitioner cannot physically connect the untreated sterilized handpiece 30 to the medical device main body 10. Therefore, the use of the unsterilized untreated handpiece 30 for other patients can be reliably controlled, and the problem of contamination can be prevented.

  In addition, the patient change detection unit 11h detects whether the handpiece 30 has been sterilized or not sterilized before the operation of the patient after the change by detecting the change of the patient based on the sitting of the patient after the next change to be changed. Since the determination can be made, it is possible to prevent the use of the sterilized untreated handpiece 30 for the patient after the change. Therefore, the practitioner can safely treat the patient after the change.

In addition, the patient change detection unit 11h is configured to detect the change of the patient based on the end information of the operation based on the patient getting out of the medical chair 71, so that the patient change after the patient's operation is completed. Before the treatment, it can be determined whether the handpiece 30 has been sterilized or not yet sterilized. As a result, since the use of a non-sterilized medical device can be reliably controlled before the operation of the patient after the replacement, even if it is forgotten to remove the handpiece 30 from the medical device body 10, it is not sterilized. The use of the processing handpiece 30 can be prevented more reliably.
Furthermore, since the handpiece 30 that can be used for the treatment can be confirmed before the treatment of the patient after the change, the practitioner can smoothly perform the treatment of the patient after the change.

  Further, a treatment detection unit 51g that detects the use of the handpiece 30 and a holder light output unit 17a that notifies at least the use of the used handpiece 30 for each handpiece 30 based on the detection result of the treatment detection unit 51g. Since only the holder light output unit 17a of the holder 14 that holds the handpiece 30 actually used for the treatment is notified by being provided in the holder 14, only the notified handpiece 30 may be sterilized. Therefore, the object to be sterilized becomes clear at a glance.

  Moreover, since use can be alert | reported for every handpiece 30, the handpiece 30 which should be replaced | exchanged before performing another patient's treatment can be determined easily. Therefore, the practitioner can clearly and easily determine the handpiece 30 to be replaced, and can perform a smooth treatment.

  Moreover, the holder light output part 17a is a structure which is provided in the holder part of the handpiece 30, and lights or blinks a lamp etc. for every handpiece 30 which should be replaced | exchanged. As a result, the practitioner can recognize that only the handpiece 30 that has been used once has to be sterilized because the lit or blinking lamp is always in the field of view when performing the treatment for the next patient. The reuse of the handpiece 30 can be reliably avoided.

  In addition, a connection determination unit 11 i that detects replacement of the handpiece 30 based on information obtained by the proximity detection sensor 435 and a drive control unit 11 f that releases use restriction of the handpiece 30 are provided. Thus, the use restriction can be released by exchanging the use-restricted handpiece 30 with a sterilized handpiece 30. Thereby, the practitioner can recognize that the handpiece 30 that can be used for the treatment is connected to the medical device body 10. Therefore, the practitioner can concentrate on the treatment without worrying about whether or not the handpiece 30 has been replaced after the change of the patient.

  Further, a sterilization process number storage unit 52d that stores the number of sterilization processes that have been sterilized is provided, and the drive control unit 11f regulates the use of the handpiece 30 based on the sterilization process information O and the number of sterilization processes. By using the feature, it is possible to prevent the handpiece 30 that has deteriorated due to the sterilization treatment from being used for the treatment.

  More specifically, when the handpiece 30 is sterilized using an autoclave, the handpiece 30 is kept under a high temperature and high pressure condition for a predetermined time. There was a risk that it could deteriorate and become unusable during the treatment.

  However, when the drive control unit 11f is configured to restrict the use of the handpiece 30 based on the sterilization processing information O and the number of sterilization processes, the handpiece 30 can be used when the handpiece 30 exceeds the predetermined number of sterilization processes. The use of the handpiece 30 can be restricted and the driving of the handpiece 30 can be prevented from stopping during the treatment. Therefore, the practitioner can perform the operation with peace of mind.

  Further, by providing a replacement determination unit 11k that determines whether or not the handpiece 30 needs to be replaced based on the number of times of sterilization, and a monitor 15 that performs predetermined notification based on the determination result of the replacement determination unit 11k, Even if the piece 30 has been sterilized, the practitioner can recognize that the handpiece 30 should be replaced before the operation, and can replace the handpiece 30 with a usable one. Thereby, it is possible to perform the treatment smoothly without exchanging the handpiece 30 during the treatment, and it is possible to prevent the patient from feeling uneasy.

  Moreover, when it is set as the structure which can set the processing temperature and processing time of an autoclave to the optimal processing temperature and time according to the handpiece 30, the judgment criteria of durability of the handpiece 30 change according to these processing conditions. However, since the number of sterilization treatment times 51h is provided, the number of sterilization treatments can be converted into the number of sterilization treatments based on the standard number of sterilization treatments according to the sterilization treatment conditions. Even if the sterilization conditions are different, the number of times the handpiece 30 has been sterilized can be calculated according to a predetermined standard. Thereby, for example, the limit number of sterilization processes of the handpiece 30 stored in advance in the replacement reference information storage unit 12c and the integrated value of the calculated number of sterilization processes can be compared and determined to notify the necessity of replacement of the handpiece 30. The practitioner can grasp the replacement time of the handpiece 30.

  As described above, even when sterilization is performed under various sterilization conditions, the replacement time of the handpiece 30 can be determined based on a predetermined standard. Even when sterilization is performed over a longer period of time, the practitioner can accurately grasp the replacement time of the handpiece 30, and a sterilization apparatus with a near replacement time can be safely operated. The piece 30 can be replaced in advance.

  In addition, the sterilization processing determination unit 11d compares and determines the sterilization time and the use time of the handpiece 30 to determine whether the sterilization process has been performed or not yet sterilized, thereby determining the use time of the handpiece 30 and the sterilization process. It is possible to determine whether the handpiece 30 has been sterilized or not yet sterilized on the basis of the time of the above, and to accurately determine the front and back of the use time of the handpiece 30 and the sterilization time.

  That is, the handpiece 30 that has not been sterilized after use is connected to the medical device main body 10, or the handpiece 30 that has been used after sterilization is connected to the medical device main body 10. Since it can be determined that the piece 30 has not been sterilized, use of the handpiece 30 that has not been sterilized can be reliably regulated.

  In addition, for example, in the case of comparing and determining the date and time of the sterilization process and the date and time of the handpiece 30, the sterilization process is performed after the handpiece 30 is used. However, since the time has passed since the sterilization process, it can be determined whether the sterilization process is necessary again, and the reuse of the handpiece 30 can be prevented.
