In the radioactivity administering medical liquids device 1 of present embodiment, above-mentioned force cell 33 is not only for detection of the overload state in the administration pipeline 7, also for detection of liquor charging defective modes such as the leakage in the administration pipeline 7 or adverse currents.The liquor charging defective mode refers to that radioactivity medicinal liquid or normal saline are not sent to the front of administration pipeline 7 (testee's side) and leaks or the state of adverse current.Controlling organization 34 is according to judging from the detected value of force cell 33 inputs whether administration pipeline 7 is in overload state or liquor charging defective mode.Whether whether controlling organization 34 storage is that the judgment standard of overload state is upper limit threshold, and be that the judgment standard of liquor charging defective mode is lower threshold (with reference to figure 3).Driving load when upper limit threshold is higher than normal the operation, the driving load when lower threshold is lower than normal the operation.
Below, describe handling (defective mode detection method) based on the administration of controlling organization 34.Fig. 2 is the flow chart of the administration treatment step in the expression controlling organization.As shown in Figure 2, as if the indication that begins to supply with the radioactivity medicinal liquid by the inputs such as operator of radioactivity administering medical liquids device 1, then the syringe stem of RI syringe 31 is driven, and the radioactivity medicinal liquid spues towards the 3rd flexible pipe 19C.Afterwards, controlling organization 34 injector-actuated bar 31(S1).If syringe stem 31 drives, then the radioactivity medicinal liquid is pressed into normal saline and to testee's administration.

If be judged as detected value from force cell 33 input less than upper limit threshold in step S2, then whether controlling organization 34 is judged from the detected value of force cell 33 inputs below lower threshold (S3).If be judged as detected value from force cell 33 input in step S3 below lower threshold, then controlling organization 34 is used as oneself and is detected the liquor charging defective mode in the administration pipeline 7 and stop syringe stem 31(S4).
If be judged as detected value from force cell 33 input greater than lower threshold in step S3, then controlling organization 34 judges whether dosage reaches setting value (S5).The judgement is here for example undertaken by time and the predetermined administration time that relatively begins from the driving of syringe stem 31.Oneself reaches setting value if be judged as dosage in step S5, and then controlling organization 34 stops syringe stem 31(S6), and the administration of end radioactivity medicinal liquid.If being judged as dosage in step S5 does not reach setting value, then controlling organization 34 is got back to the processing of step S2, carries out the judgement whether administration pipeline 7 is in overload state or liquor charging defective mode repeatedly.
Fig. 3 is the figure that schematically illustrates based on the relation of the detected value of load detector structure and upper limit threshold and lower threshold.Further investigation by inventor etc. is clear and definite as follows: as shown in Figure 3, just often when bad, produce 7 times poor at the 1st check-valves 21a in the detected value approximately.Therefore, the detected value when bad less than the 1st check-valves 21a by lower threshold is made as can detect the bad of the 1st check-valves 21a.In addition, in step S3, be used as oneself and detect the liquor charging defective mode in the administration pipeline 7 and when stopping syringe stem 31, be not limited to the 1st check-valves 21a, for example can also infer breakage owing to the breakage of the 2nd check-valves～the 4th check-valves 19B～19D or filter 22, forget that the 2nd pinch valve 56B is installed waste liquid flexible pipe 53 or waste liquid flexible pipe 53 breaks away from the probability towards the leakage of waste liquid bottle 10 sides that causes.
According to radioactivity administering medical liquids device 1 and the defective mode detection method thereof of present embodiment, by the syringe stem 31 that drives normal saline syringe 30 normal saline is injected the front of administration pipeline 7 and supplies with the radioactivity medicinal liquid.At this moment, detect the driving load of the syringe stem 31 in the syringe stem drive division 32 by force cell 33.When passing through force cell 33 detected detected values when lower threshold is following, detect the liquor charging defective mode by controlling organization 34.Thus, can test example as in administration pipeline 7, producing the probability of leak of liquid or adverse current etc.Thus, the force cell 33 that arranges in order to detect overload state can be used for the detection of liquor charging defective modes such as leakage or adverse current.Therefore, need not other design flow equipment etc. just can be with simple structure detection liquor charging defective mode.
And, between normal saline bag 3 and normal saline syringe 30, be provided with the 1st check-valves 21a.When the 1st check-valves 21a takes place when bad, therefore the liquid in the administration pipeline 7 might have the anxiety that can not supply with the radioactivity medicinal liquid with desirable dosage to normal saline bag 3 adverse currents.According to this defective mode detection method, can be inferred as the 1st check-valves 21a with simple structure has bad probability.
As radioactivity administering medical liquids device 1, in the time of especially in major part is contained in casing 13, be difficult to confirm like a cork device type.And, administration pipeline 7 or normal saline syringe 30 most of for disposable (with after namely abandon), therefore change frequently.Therefore, in addition the equipment of design flow flow etc. also is difficult.According to radioactivity administering medical liquids device 1, owing to the force cell 33 in the syringe stem drive division that does not contact with radioactivity medicinal liquid liquid 32 that utilizes non-once, it is bad therefore can to detect liquor charging effectively with simple structure.
More than, describe in detail for embodiments of the present invention, but the invention is not restricted to above-mentioned embodiment.For example, when passing through force cell 33 detected detected values when lower threshold is following, can after changing filter 22, detect the driving load of syringe stem 31 again by force cell 33.At this moment, because filter 22 is arranged at outside the casing 13, therefore change easily.And, change this filter 22 after, drive load by detecting again with force cell 33, can judge whether the reason that the pressure in the administration pipeline 7 descend is filter 22.Thus, can infer the reason that administration pipeline 7 is bad like a cork.
In addition, can also use method same as described above in the radioactivity administering medical liquids device in filter is arranged at casing.Also can judge whether the reason that the pressure in the administration pipeline descends is filter this moment.
And above-mentioned defective mode detection method is not limited to supply with based on radioactivity administering medical liquids device 1 situation of radioactivity medicinal liquid.For example, also can be applicable to the situation of before using radioactivity administering medical liquids device 1, utilizing normal saline to clean.
And, be not limited to the situation of force cell as the load detector structure, for example can utilize the current value in the syringe stem drive division 32 in controlling organization 34 grades, to detect the driving load.At this moment, the load detector structure constitutes the part of the function of controlling organization 34.
And, in the above-mentioned embodiment, for in the bad detection of liquor charging, utilizing the situation of the detected value of the force cell 33 that is arranged at normal saline syringe 30 to be illustrated, but so long as for example be connected in the radioactivity administering medical liquids device of the type of administration pipeline independently with syringe and normal saline syringe to medicinal liquid (radioactivity medicinal liquid), then can in the bad detection of liquor charging, utilize to be arranged at this to the detected value of medicinal liquid with the force cell of syringe.At this moment, be equivalent to liquor charging syringe of the present invention to medicinal liquid with syringe.
