Hereinafter, when the spherical groove 18 moves from position to position and from position to position, the pan 2 swings in the same manner as described above, and thereafter the pan 2 of the blood collection bag repeats vertical swinging in the front-back direction and vertical swinging in the left-right direction simultaneously. .

A control device 80 is provided inside the front of the housing 5.
Is built-in. The control device 80 includes a control unit 81 and a driving unit 82 as shown in FIG. The control unit 81 includes a CPU (central processing unit) (including a memory in which a program for controlling a series of operations of the blood collection device 1 is written) 85, a storage unit 86, and an input / output circuit 88. A detection signal of the sensor 23 for detecting the swinging speed of the tray (the fixed position stop sensor 97) is transferred to the input / output circuit 88. Storage means 86
Can store data such as a tare amount of a blood collection bag, a negative pressure generated in the storage space 10, and a set blood collection amount. The control unit 81 includes a display 83, various switches SW,
The operation panel 60 having the drive circuit DC and the setting panel 59 are connected, and these input data are transferred to the control unit 81. The drive unit 82 is connected to the control unit 81 and includes two conversion circuits A / D (analog → digital) and D / A (digital → analog). The weight measuring means 3 and the pressure sensor 93 are connected to one conversion circuit A / D via a switch 92 and an amplifier AP, respectively. The other conversion circuit D /
Motor A is connected to A via a drive circuit DC. Further, a vacuum pump 30 is connected to each of the other drive circuits DC via a clamp solenoid 94, a vacuum solenoid 95, and a power control unit 87. The clamp solenoid 94, the vacuum solenoid 95, the vacuum pump 30, the motor 7 is controlled.

Next, a method of controlling the pressure of the blood collecting apparatus 1 will be described. There are four types of pressure control methods: automatic, strong, weak, and off. Auto is the most common choice. The pressure is controlled while measuring the change in blood collection volume. Strong and weak continue suction at a constant pressure. The target value of the pressure and the rate of change of the pressure rise are different between the strong and the weak. In the off state, the pressure control is not performed at the atmospheric pressure. FIG. 13 is a block diagram when pressure control is performed.
Is a graph showing changes in pressure and time. The pressure is detected by a signal from the pressure sensor 93. In controlling the pressure, the power supplied to the vacuum pump 30 is continuously changed by the power control unit 87, the pressure release valve 39a is closed, and the vacuum pump 30 is operated to make the inside of the storage space 10 (vacuum chamber) a negative pressure. be able to. When the pressure is rapidly reduced, the pressure is released by opening the pressure release valve 39a. Hereinafter, the pressure control method will be described in detail. (A) Method of controlling to a constant pressure The vacuum pump 30 is operated with a predetermined capacity.
When the storage space 10 (vacuum chamber) reaches the target pressure, the vacuum pump 30 is thereafter operated to maintain the target pressure.
Is changed using the power control unit 87. However,
Since there is some air leakage in the system, the vacuum pump 30 is operated continuously without stopping. This method can control the rate of change of the pressure rise regardless of the target value of the pressure. By changing the capacity of the vacuum pump 30 before the pressure reaches the target value, it is possible to perform more various pressure controls. (B) Automatic control of pressure After the start of the blood sampling operation, the storage space is set on condition that the change in the measured value of the blood collection amount by the weight measuring means 3 is reduced while the negative pressure in the storage space 10 is increased toward the target high pressure level. 10
After reducing the negative pressure inside to the target low pressure level, it is raised again to the target high pressure level, and these pressures are repeated until the set blood collection volume is reached.

Next, a method of controlling the swing speed of the blood collecting apparatus 1 will be described. FIG. 15 is a block diagram when the swing speed is controlled, and FIG.
It is a graph which shows the rocking | fluctuation speed and the change of the blood collection volume. The speed is detected based on a signal from the speed detecting sensor 23. The operation of the speed is performed by continuously changing the voltage supplied to the motor and changing the rotation speed of the motor 7. Hereinafter, a method of controlling the swing speed will be described in detail. (A) Between the start of the swing and the acceleration At the start of the swing, a low voltage is supplied to the motor 7 and the operation is started at a low speed. This prevents an excessive load from being applied to the drive unit. The voltage is increased and accelerated at a fixed rate. Next, when the voltage reaches a predetermined value, constant speed operation is performed. The predetermined value is a representative value or the like of a voltage that swings at the target speed of only the receiving tray of the blood collection bag. (B) Constant speed operation The motor 7 is driven so as to eliminate the deviation between the current position of the speed and the target value.
The voltage to be supplied to is changed. Thus, the swing can be continued at the target speed even if the swing load changes due to blood collection. In this control method, the speed detection sensor 2
Even if the signal No. 3 is obtained only once or several times per one rotation of the swing, the target speed can be reached in a short time from the start of the swing and without exceeding a large speed. (C) Deceleration When deceleration is required, the voltage supplied to the motor 7 is reduced at a fixed rate to decelerate. Thus, it is possible to prevent an excessive load from being applied to the drive unit, and to improve the positional accuracy when the swing is stopped. In addition, the time required for the fixed position stop can be shortened. This is possible because the point at which deceleration is actually started is determined by correcting the time required for deceleration from a signal from the fixed position stop sensor 97 (which can also be used as the speed detection sensor 23). Become. (D) Fixed Position Stop When a signal from the fixed position stop sensor 97 (which can also be used as the speed detection sensor 23) comes, the motor is stopped after waiting for time t1. Here, t1 is a time for correcting the stop position, and is stored in the storage unit. The stopping means of the motor 7 is performed by setting the voltage supplied to the motor 7 to 0 V or operating the control terminal if the motor 7 has a control terminal. In order to make the stop position more accurate, a signal for reverse rotation can be added for a short time after the motor 7 is stopped in order to reduce overrun of the motor 7. The means for reverse rotation is performed by supplying a negative voltage to the motor 7 or operating the motor 7 if it has a control terminal. (E) Countermeasures for abnormalities During constant speed operation, the absolute value of the deviation between the current speed and the target
If it is longer than a certain value and continues for a certain time, the motor 7 is stopped as an abnormality and an alarm is issued. If the signal of the fixed position stop sensor 97 does not reach a certain time during the fixed position stop, the motor is stopped as an abnormality and an alarm is issued.

The weight measurement during the swinging of the blood collecting apparatus 1 is performed by averaging the values of the A / D conversion during one swing. One round is detected by the speed detection sensor 23 and / or the fixed position stop sensor 97. This method has the following advantages as compared with the case where measurement is performed at a specific point during swinging. It is not necessary to adjust the position of the weight measurement signal with respect to the swing position. Further, the weight measurement is hardly affected by disturbances such as vibration during swinging and contact between the tube of the blood collection bag and the blood collection device housing.
