    Abstract: To prevent a user from accidentally pricking the user with a hollow needle when separating blood components using a syringe and a connection device. A blood component separation apparatus has three syringes and a connection device. The connection device is attached to one syringe and is inserted into other syringes. The connection device has a first member to which a base end of a hollow needle is joined and a second member which is connected to the first member in such a manner as to be able to move relative to the first member. The second member is moved back and forth between a first position where a tip of the hollow needle is accommodated and a second position where the tip of the hollow needle is exposed. The second member has elastic portions which are elastically deformed in the movement from the first position to the second position. The elastically deformed elastic portions elastically energize the second member at the second position to the first position side with respect to the first member.

    Abstract translation: 为了防止用户使用注射器和连接装置分离血液成分时用中空针不慎地刺穿使用者。 血液成分分离装置具有三个注射器和连接装置。 连接装置连接到一个注射器，并插入其他注射器。 连接装置具有第一构件，中空针的基端与该第一构件接合，第二构件以能够相对于第一构件移动的方式连接到第一构件。 第二构件在容纳空心针的前端的第一位置和中空针的前端露出的第二位置之间来回移动。 第二构件具有在从第一位置到第二位置的运动中弹性变形的弹性部分。 弹性变形的弹性部分在第二位置将第二构件弹性激励到相对于第一构件的第一位置侧。

    Abstract: A culture device supplying an accurate amount of liquid into a culture bag has a culture bag having ports, a first bag holding portion having supporting surfaces supporting the culture bag, a rotation mechanism rotating the first bag holding portion, a liquid supplying mechanism supplying a liquid through a tube communicating with the ports a weight detector detecting the weight of the culture bag and the first bag holding portion, and a control portion, in which the control portion sets a first reference value according to a first detection information output from the weight detector in a first state and carries out a liquid supplying step of stopping the liquid supplying mechanism under the condition where a second detection information output from the weight detector when a liquid is supplied to the culturing bag reaches a first target value obtained by adding the weight of the liquid to be supplied to the first reference value.
