Description

  The present invention relates to a radiation irradiating apparatus, and more particularly to a radiation irradiating apparatus that irradiates a blood bag or the like enclosing blood for transfusion with radiation containing X-rays or γ-rays.

  The blood for transfusion in the blood bag has a side effect due to blood transfusion called GVHD (Graft Versus Host Disease). In order to prevent this, radiation is applied to the blood bag to inactivate lymphocytes in the blood product for blood transfusion. As radiation, γ rays using radioisotope 137Cs (cesium) and X-rays are used.

  As a radiation irradiation apparatus in this case, for example, a two-way irradiation apparatus disclosed in Patent Document 1 is known. In general, a radiation irradiation apparatus includes an X-ray tube device (referred to as a first X-ray tube device), a sample surface (hereinafter referred to as a tray portion) arranged facing the X-ray tube device, and And a protection room that shields the incorporated X-rays. However, in the two-way irradiation apparatus, the second X-ray tube device is incorporated in the protective chamber so as to face the first X-ray tube device with the sample dish (hereinafter referred to as a tray) in between. A configuration in which X-ray irradiation is performed from both sides of the sample by both X-ray tube devices by disposing the cathode and anode of the X-ray tube device opposite to those of the first X-ray tube device. It is said. Thereby, it is possible to perform uniform irradiation in a shorter time than the conventional apparatus without rotating the tray, and to perform irradiation with a large dose.

Further, a cooling device 5 is provided, and the anodes of the upper X-ray tube device 2 and the lower X-ray tube device 3 are cooled by supplying cooling oil from the cooling device 5. The cooling oil warmed by the upper X-ray tube device 2 and the lower X-ray tube device 3 is cooled by a circulating cooling device (or tap water) 9. A dosimeter probe 7a connected to the dosimeter 7 is provided in the vicinity of the tray 13, and the X-ray dose irradiated to the tray 13 can be measured by the dosimeter probe 7a. Setting of X-ray irradiation conditions such as the dose of the upper X-ray tube device 2 and the lower X-ray tube device 3 irradiating the tray 13, message display, various data registration, and the like are made by an operation panel (touch panel) 8. ing. The tray 13, the upper X-ray tube device 2, the lower X-ray tube device 3 and the like are covered by a shielding body 1a, and the shielding body 1a prevents X-rays from leaking from the irradiation chamber 1b to the outside. The tray 13, the upper X-ray tube device 2, the lower X-ray tube device 3 and the like are housed in a protective box 1, and a tray unit 10 for carrying the tray 13 out of the protective box 1 is placed in the protective box 1. It comes to be equipped with. Further, a bar code reader 14 is provided, the bar code information is read by the bar code reader 14, and the information is transmitted to the control device 6. In addition, the personal computer 30 is connected to the control device 6 via Ethernet, and by this personal computer 30, the high voltage generating unit 4, the dosimeter 7, the cooling device 5, the circulating cooling device (or tap water) 9, the bar The code reader 14 is controlled. The personal computer 30 also provides information on the thickness of the tray 13 (identified by a bar code), the bar of a user who is a medical employee of the two-way irradiation apparatus 100 (a medical employee permitted to use the apparatus). In addition to having code information as a database, users can be notified by email that radiation irradiation has ended.

  Next, prior to the description of the operation of the radiation irradiation apparatus of the present invention, registration of the user of the two-way irradiation apparatus 100 will be described with reference to FIGS. First, as shown in FIG. 3A, each user A, B, C,... Is given a barcode indicating each user A, B, C,. These bar codes are usually printed or pasted on the name plate 15 of the user. The bar code labels of each user A, B, C,... May be created by the personal computer 30 according to each user A, B, C,. You may use a bar code. The registration can be set for the manager 60 in addition to the user. Since the manager 60 can have the key authority of the user, the two-way irradiation apparatus 100 can be used as the user. Further, as shown in FIG. 3B, it is also possible to register by grouping for each manager 60. 3B, for example, the manager A 60a in group A does not have the key authority of the users A ′, B ′, C ′,... Of group B, and the manager 60b in group B The key authority of the users A, B, C,. By performing such management, a plurality of different departments can correspond to a facility using the radiation irradiation apparatus.

  The registration method to the two-way irradiation apparatus 100 is as follows. The user's name is input from the user registration screen of the operation panel 8 and the bar code label on the name plate 15 is read by the bar code reader 14. 6 (indicated by reference numeral 6a 'in FIG. 4), the user name and barcode information are registered as a set. Deletion can be performed from the operation panel 8. In this embodiment, the barcode label on the name plate 15 is read by the barcode reader 14, but a so-called RFID method can be used instead of the barcode method. That is, when an IC tag is embedded in the name plate 15 and a receiver is installed in the two-way irradiation device 100, when the user approaches the two-way irradiation device 100, the user who has already been registered is registered. It may be possible to determine whether or not.

  Next, operation | movement of a radiation irradiation apparatus is demonstrated based on the flowchart of FIG. In FIG. 1, first, the user turns on the power of the two-way irradiation apparatus 100 (step SP1), and the two-way irradiation apparatus 100 acquires user bar code information (step SP2). Here, as shown in FIG. 4, the barcode reader 14 reads the barcode label 15a of the user (for example, printed on the name plate 15) to acquire the user barcode information by the two-way irradiation device 100. The read barcode information is sent to the database 6a ′ in the CPU module 6a via the input module 6b of the control device (sequencer unit) 6. The barcode information sent to the database 6a ′ is collated with the registered information in the user database 6a ′ registered in advance. FIG. 4 is a diagram showing an internal configuration of the control device 6 shown in FIG. 2, and is a diagram drawn together with the barcode reader 14, the operation panel 8, and the personal computer 30.

  Returning to FIG. 3, it is determined whether the user barcode information acquired by the two-way irradiation apparatus 100 is a user registered in the user database (step SP3), and it is determined that the user is not registered. In this case, the operation of the apparatus becomes impossible, and it is displayed on the operation panel 8 that the user is not registered (steps SP4 and SP5). If it is determined in step SP3 that the user is a registered user, use of the two-way irradiation device 100 is permitted, and an operation screen is displayed on the operation panel 8 (step SP6). Next, the user sets a tray (step SP7). Specifically, the operation in this case will be described. First, the tray unit 10 shown in FIG. 1 is unloaded by operating the unloading switch on the operation panel 8, and the tray 13 is set on the tray unit 10. The tray unit 10 is carried into the irradiation chamber 10b by operating the switch. At this time, the user is stored (registered) in the CPU module 6a as the user who has set the tray 13 (step SP8).

  Thereafter, the operation of the X-ray irradiation switch on the operation panel 8 becomes effective, and the X-ray irradiation is started when the user presses the X-ray irradiation start switch (step SP9). In this case, as shown in FIG. 1, the upper X-ray beam 2a and the lower X-ray beam 3a, which are X-ray beams irradiated on the tray, are taken into the dosimeter probe 7a of the dosimeter 7, and the dosimeter 7 reaches a predetermined dose. It is to measure whether or not. Thus, when the X-ray beam reaches a predetermined dose, the radiation irradiation is stopped and the irradiation is completed (step SP10).

  After the irradiation is completed, the user can read the barcode 1 of the name plate 15 again with the barcode reader 14. The bar code information of the user is sent into the CPU module 6a via the input module 6b of the control device (sequencer unit) 6 as shown in FIG. 4, and the tray 13 stored in the CPU module 6a is stored in the tray 13. Collation with the set user information is performed, and it is determined whether or not the collation matches (step SP11). If the verification matches, the tray can be carried out (step SP12). However, if it is determined that the user is not the user who set the tray 13, electronic key lock control is performed and the tray carry-out switch becomes invalid, and the tray 13 cannot be taken out (step SP13).

  Then, it is determined whether or not the tray 13 has been taken out after a lapse of a certain time after completion of X-ray irradiation (step SP14). When it is determined that the tray 13 has not been taken out, the user is notified of the completion of X-ray irradiation (step SP15). Here, in order to contact the user, as shown in FIG. 4, an instruction to deliver an irradiation completion notification mail is automatically sent from the CPU module 6a to the personal computer 30 via the external communication module 6c. The irradiation completion notification mail 32 is delivered to the PC or designated mobile phone. Here, if the tray 13 is not taken out even when the irradiation completion notification mail 32 is delivered, the tray may be taken out instead of the user by reading the bar code of the manager responsible for the user's authority. Good.

  As is clear from the above description, the radiation irradiation apparatus configured as described above determines whether the user is permitted on the radiation irradiation apparatus side, and the radiation irradiation apparatus must be a user who has set the tray. Use is not permitted, and radiation irradiated trays cannot be removed. Further, in certain cases, the user is notified that the radiation irradiation has ended. Therefore, according to the radiation irradiation apparatus of this invention, it can operate reliably by the appropriate user. In addition, the user can be notified within an appropriate time that the irradiation has been completed.

  In Example 1, as a radiation irradiation apparatus, for example, a two-way irradiation apparatus is shown as an example. However, the present invention is not limited to this, and can be applied to a radiation irradiation apparatus that irradiates radiation containing X-rays or γ rays to a blood bag or the like that encloses blood for transfusion.

  The present invention has been described using the embodiments. However, the configurations described in the embodiments so far are only examples, and the present invention can be appropriately changed without departing from the technical idea. Further, the configurations described in the respective embodiments may be used in combination as long as they do not contradict each other.
