Further, by operating the operation unit 12 of the second syringe pump 1, the second patient data stored in the second syringe pump 1 is changed to the first patient data, or the first syringe pump It becomes possible to select whether to change the first patient data stored in 1 to the second patient data at once (step S5). Here, when it is selected that the second patient data of the second syringe pump 1 is changed to the first patient data, the patient data of the second syringe pump 1 is changed to the first patient data, and the medical data is used. Patient data stored in all syringe pumps 1 installed on the pump mount 20 becomes the first patient data, and consistency can be obtained (step S7). Moreover, if it chooses to change the 1st patient data memorize | stored in the 1st syringe pump 1 into 2nd patient data collectively, at least 1 set | placed in the medical pump mount 20 will be carried out. The patient data of the first syringe pump 1 are collectively changed to the second patient data, and the patient data stored in all the syringe pumps 1 installed on the medical pump mount 20 are the second patient data. It becomes data and can be consistent (step S8).

Next, referring to FIG. 5, the first syringe pump 1 in which at least one first patient data is stored in the medical pump mount 2 and the second in which the first patient data is stored. When the first syringe data stored in the second syringe pump 1 is changed to different second patient data in the case where the first syringe pump 1 is installed (step S21), the patient data consistency management is performed. The method of performing will be described.

In the second syringe pump 1, the medical staff manually inputs patient data second by manual operation on the operation unit 12 and the setting dial 6, or is attached to the wristband 34 attached to the arm of the patient 37. The barcode 35 containing the second patient data is read by the portable device 36 and the communication module mounted on the portable device 26 corresponding to the wireless communication module (not shown) mounted on the syringe pump 1 When performing the patient data input operation by transferring the second patient data by wireless communication with (not shown) (step S22), the second syringe pump 1 is displayed with the input operation as a trigger. A warning is displayed on the unit 10, and an alarm is sounded by a buzzer (not shown) to prompt the medical staff to confirm. And a medical worker discards the 2nd patient data which is going to be memorize | stored in the 2nd syringe pump 1 by operating the operation part 12 of the 2nd syringe pump 1, and maintains it as 1st patient data. It is possible to select whether to change the first patient data stored in the first syringe pump 1 to the second patient data collectively (step S23). Here, when discarding the second patient data to be stored in the second syringe pump 1 and maintaining the first patient data is maintained, the patient data of the second syringe pump 1 is changed. First, the consistency of patient data stored in all syringe pumps 1 installed on the medical pump mount 20 can be ensured (step 26). Moreover, if it chooses to change the 1st patient data memorize | stored in the 1st syringe pump 1 into 2nd patient data collectively, at least 1 set | placed in the medical pump mount 20 will be carried out. The patient data of the first syringe pump 1 are collectively changed to the second patient data, and the patient data stored in all the syringe pumps 1 installed on the medical pump mount 20 are the second patient data. It becomes data and can be consistent (step S25).

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that a design change or the like within a range that does not depart from the spirit of the present invention is included in the present invention. Needless to say, the fixing method of the gantry 2 is not limited to the above-described one-touch method, and it is naturally possible to use a screw-fixing method as used in a conventional pump tray instead of the one-touch method.
