[0050]

[Equation 1]

D The CPU 65 sets the tube clamp 4 on condition that the residual blood collection amount, which is the result of the above calculation, has reached zero.

G Same as f above.

In both of the above cases, the amount of blood collected and the degree of vacuum during blood collection can be displayed on the display unit 57 to monitor the progress of measurement. The display amount is selected by the changeover switch 50.

In the blood collecting apparatus 10, however, the increase rate α of the blood collected in the blood bag 1 is controlled in the blood collecting work process described above as follows.

That is, the CPU 65 of the control device 18
The increase rate α of the blood sampling amount measured by the scale 33 is controlled in the blood sampling process. The rate of increase in the amount of collected blood is the rate of increase in the amount of collected blood with respect to the elapse of the measurement time. It is calculated by the rate of increase in the amount of blood collected relative to the amount of blood collected previously.

Therefore, according to the blood collection device 10, after the blood collection is started, the amount of blood collected in the blood bag 1 is measured by the scale 33, and the CPU 65 collects blood while controlling the increase rate α of the measured blood collection amount in the blood collection process. To proceed. Therefore, blood can be collected at a blood increase rate α that does not burden the donor. In addition, since the increase rate α of the blood collection amount is used as a control amount, the increase rate becomes an abnormal state in which it decreases from the normal level due to “the needle hole of the blood collection needle adsorbs the blood vessel wall and becomes blocked”. It is possible to avoid falling, and improve blood collection efficiency even for a donor with a thin blood vessel without causing difficulty or inability to collect blood.

In the practice of the present invention, the control method of the blood increase rate α is, for example, the following (A), (B), (C).
It can be either.

(A) Measured increase rate α by the CPU 65
Is a control method in which the negative pressure level of the vacuum blood collection chamber 13 is continuously controlled to be reduced until the predetermined increase rate α ₀ or more. According to this, by setting the measurement increase rate α in advance to an appropriate set increase rate α ₀ , it is possible to realize a proper blood collection state in which the burden on the blood donor is reduced and the blood collection efficiency is improved. Specifically, for example, one of the following is used.

In order to maintain the negative pressure level P ₀ of the blood collection chamber 13 when the measured increase rate α reaches the set increase rate α ₀ ,
The negative pressure level of the vacuum blood collection chamber 13 is controlled.

The negative pressure level Px of the blood collection chamber 13 is controlled so that the measured increase rate α maintains the set increase rate α ₀ .

In the above (A), the set increase rate α
₀ is stored in the memory 66 as described above. Where α ₀ is C
It can be stored in the internal memory of the PU 65.

(B) A control method in which the negative pressure level in the blood collection chamber 13 is continuously reduced until the measured increase rate α by the CPU 65 reaches the saturation increase rate αmax at which it no longer changes. According to this, the final value of the blood increase rate α is set to the saturation increase rate αmax
By adopting the above, the blood collection efficiency can be further improved under the condition in which the burden on the donor in the intermediate blood collection process is reduced as much as possible. Specifically, for example, one of the following is used.

The negative pressure level in blood collection chamber 13 is controlled so as to maintain the negative pressure level P0 in blood collection chamber 13 when measured increase rate α reaches saturation increase rate αmax.

The negative pressure level Px of the blood collection chamber 13 is controlled so that the measured increase rate α maintains the saturation increase rate αmax.

(C) The CPU 65 controls the negative pressure level of the blood collection chamber 13 so that the measured increase rate α changes with a predetermined specific increase rate pattern as the blood collection time t elapses. According to this, it is possible to proceed with blood collection according to a specific increase rate pattern determined in consideration of reducing the burden on the blood donor and improving the blood collection efficiency. This means that, for example, by adopting the increase rate pattern, the burden on the donor is reduced and the occurrence of hemolysis is prevented by the gentle increase pattern in the initial stage of blood collection up to the elapsed time tx, and blood collection after the elapsed time ty. In the final stage, the gradual reduction pattern can improve the accuracy of blood sampling.

In the above (A), (B), and (C), the operation of reducing the negative pressure level of the blood collection chamber 13 can be performed stepwise or continuously with the elapse of the blood collection time. In addition, when it is made stepwise, the CPU 65 extracts the measured increase rate α each time the negative pressure level reaches each step.

Further, in (A), (B),
, (C), the operation of controlling the negative pressure level of the blood collection chamber 13 is performed by on / off control of the a vacuum pump 17 or on / off control of the pressure control valve provided in the b vacuum pipe 41 or analog control. To be done. That is, in the above a and b, the CPU 65 controls ON / OFF of the power supply switch 77 of the pump 17 so that the pressure detected by the pressure sensor 73 matches the target pressure stored in the memory 66, for example. ON / OFF control or analog control of the pressure control valve.

The present invention can be widely applied to any blood collecting apparatus in which the measuring method of the blood collecting amount measuring means and the pressure adjusting method of the vacuum blood collecting chamber are used.

[0078]

As described above, the blood collecting device of the present invention includes the blood container mounting base for accommodating the blood container, the swinging means for swinging the blood container mounting base, the blood container mounting base and the swinging means. Since the blood collecting device is provided with the covering member for covering the swinging means between the two, it is possible to prevent foreign matter from entering the gap between the blood bag and the casing of the main body or the driving means.

Since it is further provided with a vacuum blood collection chamber in which the pressure is reduced by the vacuum pump and the blood container is set,
It is possible to prevent foreign matter from entering the gap between the blood bag and the casing of the main body or the drive means, and to quickly collect blood at a blood increase rate that does not burden the donor.

Further, the swing extension time data set by the swing extension time setting means is to be stored in a storage means capable of being rewritten and read and capable of holding stored data even without application of a power supply voltage. With this, it is not necessary to repeatedly set the rocking extension time after the end of blood collection each time the power is turned on and the device is operated, and the rocking extension time can be easily set according to the user's use conditions. it can.
