Manipulating tool
摘要:
A storage and manipulating tool for replacement plunger heads includes a set of storage cavities in which replacement plunger heads (syringe tips) are stored. Each plunger head has an annular flange, and a socket for receiving the end of a cooperating plunger shaft and is stored in its cavity with its socket facing the open end of the storage cavity. The tool also includes elongated passage defining structure for receiving a related plunger shaft. The cross-sectional dimension of the elongated passage is uniform along its length and is less than the annular flange portion of a replacement plunger head stored in a cavity such that axial movement of a plunger shaft in the elongated passage is effective to remove the attached plunger head. The exposed attachment end of the plunger shaft is then inserted into a storage cavity to attach a replacement plunger head for removal from the storage cavity without handling the sealing surfaces of the plunger head.
