Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifuge, and particularly to storing operating conditions for each of a plurality of replaceable rotors,
And a centrifuge capable of recalling stored operating conditions.

[0002]

2. Description of the Related Art Conventionally, centrifuges have been widely used to analyze sample components in the medical field and the like. Among these centrifuges, there are centrifuges configured so that a plurality of different types of rotors can be used by being changed according to the type and amount of the sample to be analyzed, the purpose of analysis and the like. In addition, depending on the purpose of analysis, it may be necessary to repeatedly operate the operating conditions such as the set rotor speed, operating time, and temperature under the same conditions. There is also a centrifuge having a function capable of calling operating conditions.

Here, as a centrifuge capable of storing the existing operating conditions and recalling the stored operating conditions, the operating conditions such as the set rotational speed of the rotor, the operating time, and the temperature can be stored in the centrifugal separator. It was a centrifuge having a function of storing it regardless of the type and recalling the stored operating conditions regardless of the type of rotor.

That is, a concrete example of the above centrifuge will be described with reference to the configuration diagram of the operation panel of the centrifuge shown in FIG. 3. When the number of revolutions is set by this operation panel, the number of revolutions setting switch is set. Press (SPEED) 101 and turn the value change dial 102 to set an arbitrary number of rotations. Similarly, in order to set the operating time or the temperature, the operating time setting switch (TIME) 103 or the temperature setting switch (TEMP) 104 is pressed to change the numerical value changing dial 10 respectively.
Turn 2 to set any operating time or temperature. The operating conditions such as the set rotational speed are displayed on the rotational speed display unit 105, the time display unit 106, and the temperature display unit 107, respectively.

Next, the number of revolutions, the operating time set above,
To store the operating conditions such as temperature and temperature in the memory number 1 (MEMORY1) 108 for repeated operation, for example, while pressing the memory switch (STORE) 109, press the memory number 1 (MEMORY1) 108,
The set operating conditions are stored in a storage location in a RAM (not shown) corresponding to the memory number 1. The same operation is performed when the operating conditions are stored in the memory number 2 (MEMORY 2) 110 and the memory number 3 (MEMORY 3) 111. Then, the memory number 1 (ME
When operating the centrifuge under the operating conditions stored in MORY1) 108, memory number 1 (MEMORY 1)
1) Press 108 and the RAM corresponding to the memory number 1
The above operating conditions stored in the internal storage location are called, and the start switch (START) 112 is pressed to perform the operation. The storage of the operating conditions and the calling operation of the stored operating conditions are performed regardless of the type of the rotor, and the same operation is performed in the centrifugal separator in which the rotors can be changed.

[0006]

By the way, since the type and amount of the sample that can be handled for each rotor, the maximum permissible rotation speed, etc. are determined for each rotor, the rotation speed, the operating time, the temperature, etc. are naturally determined. The setting of operating conditions is often different for each rotor. Here, in the above-mentioned conventional centrifuge, since the memory number (for example, the memory number 1) of the operating conditions and the storage location in the RAM have a one-to-one relationship, the user, for example, may use the rotor A and the rotor B. In the case of owning the two types of rotors, the memory number (for example, memory number 1) in which the operating condition is stored in the rotor A cannot store different operating conditions in the rotor B. Therefore, if the number of types of rotors handled increases,
Therefore, many memory number keys on the operation panel are required, but in a normal operation panel, there are only a few memory number keys as shown in FIG. 3, and many types of rotors are used. There was a problem that the number of memories that can be used by one type of rotor was limited.

Further, in order to solve the above problems, if the number of memory number keys on the operation panel is simply increased, the user needs to store the memory number storing the operating conditions of the rotor for each rotor. If the memory is ambiguous, it often happens that the user presses a different memory number key, and rather the operability deteriorates.

The present invention has been made in view of the above-mentioned problems of a centrifuge capable of storing the above-mentioned conventional operating conditions and recalling the stored operating conditions. An object of the present invention is to provide a centrifuge capable of storing operating conditions for each type of rotor and recalling the stored operating conditions regardless of the type.

[0009]

In order to achieve the above-mentioned object, the present invention provides a means for identifying a plurality of different replaceable rotors and operating conditions such as rotational speed and operating time that can be arbitrarily set. Setting means, means for storing the operating conditions set by the operating condition setting means for each type of rotor identified by the rotor identifying means, and identification by the rotor identifying means from the operating condition storage means And a means for calling the operating conditions for each type of rotor.

[0010]

According to the centrifuge according to the present invention described above,
Since the storage of operating conditions and the recall of the stored operating conditions are performed for each rotor type identified by the rotor identification means, each rotor can have the number of memories determined by the number of memory number keys on the operation panel. Therefore, the number of memories that can be used by one type of rotor is not limited by the number of types of rotors that can be handled, and the inconvenience caused by the shortage of the number of memories can be eliminated.

Further, according to the above-described centrifuge according to the present invention, if the user selects the rotor to be used and mounts it on the centrifuge, only the operating conditions of the rotor type identified by the rotor identifying means are selected. Is called from the storage means and its memory operation becomes possible, so that the operability is improved.
