FIG. When the blood is transferred from the bag 20 to the bag 21 after centrifugation, the blade portion 46 of the communication piece 26 is broken from the thin portion 43 to allow the blood component separated from the blood bag 20 direction to flow as shown in FIG. However, since the conventional communicating piece 26 is formed symmetrically with respect to the center line O as viewed from the front and side directions, and the outer diameter of the blade portion 46 is larger than the inner diameter of the opening portion 48, the map liquid 1 into the bag 20 as shown in FIG.
Since the liquid flows in (backflows) from the upstream direction of the blade portion 46 as in No. 1, the opening portion 48 may be temporarily blocked. For this reason, the flow was poor and it was difficult to maintain the flow rate constantly. Therefore, the present inventor has arrived at the next invention as a result of intensive studies to solve the above problems.

The invention provides a communication piece for a medical bag, in which the front slope is formed longer than the back slope.

液体の安定した流路を確保することができる。The blade portion 3 has the largest diameter in the middle portion,
It is formed with a small diameter toward the front end direction and the rear end direction.
By forming the slope 6 on the front side to be long and the slope on the back side 7 to be short, the communication piece 1 is formed asymmetrically with respect to the center line O when viewed from the side direction. Therefore, when the blade portion 3 is cut from the thin portion 4, the blade portion 3 loses balance and is easily tilted to the left and right. FIG. 7 shows a usage state diagram of the communication piece 1. When the body portion 2 is gripped from the outside of the connecting cylinder 8 and the thin portion 4 is broken by applying finger pressure to the blade portion 3, the blade portion 3 tilts to the right as shown in FIG. Since it is not blocked by the rear end of the blade 3, it is possible to secure a stable flow path for the liquid flowing in from the upstream of the blade 3.

(Note 1) Unit of width, length, etc. of each side (mm) (Note 2) Unit of flow velocity (sec / 100 ml) (Note 3) The flow velocity is 100 ml of liquid flowing from the upstream side of the blade to form the communicating piece. It was calculated by passing time. In addition, it measured each 6 times and described these average values as an average flow velocity.

In the present invention, as shown in FIG. 8, it is possible to secure a wider channel by forming the groove 10 on the outer periphery of the blade 3a to reduce the cross-sectional area.

Therefore, a stable flow path for the liquid flowing in from the upstream of the blade portion 3 can be secured, and the liquid transfer work can be efficiently performed.
