摘要： A biological electrode capable of realizing good contact with a skin of a subject for detection. The biological electrode includes an electrode member, a support shaft member for supporting the electrode member, a frame member for slidably holding the support shaft member in an axial direction thereof, and an elastic member for biasing the electrode member toward the outside in the axial direction of the support shaft member. The support shaft member and the frame member have a rotation guide mechanism that converts a part of a pressing force when the electrode member is pushed in the axial direction of the support shaft member into a rotation force in which the support shaft member is a rotation axis thereof, the electrode member is pushed in the axial direction while rotating in the peripheral direction of the support shaft member by being pressed in the axial direction, and, when the pressing force for pushing the electrode member is released, receiving the bias from the elastic member, the electrode member returns while rotating in the reverse direction to that when it is pushed in.

摘要： An object of the present invention is to provide a liquid injection attachment enabling a simple liquid injection into a feed port by merely mounting the attachment onto the distal portion of a pipette or a pipette tip when liquid is injected into the feed port, as well as capable of exhibiting an excellent sealing performance without a risk to deform or damage the pipette or the pipette tip, to thereby suppress leakage of liquid during the liquid injection. The object is achieved by a liquid injection attachment removably mounted on a pipette injecting liquid into a feed port through which liquid is introduced or on a pipette tip fitted to the pipette, the attachment including a tubular attachment body having at its distal end a liquid outlet and having at its proximal end an insertion port into which a distal portion of the pipette or of the pipette tip is inserted; and a gasket formed from a rubber-like elastic body disposed around the liquid outlet of the attachment body.
摘要翻译：本发明的目的是提供一种液体注射附件，其能够通过在将液体注射到进料口中时将附件安装到移液管或移液管尖端的远端部分上而简单地注入进料口，以及能够表现出优异的密封性能而不会使移液管或移液管尖端变形或损坏的风险，从而抑制液体注入期间液体的泄漏。该目的是通过可移除地安装在移液管上的液体注射附件来实现的，该移液管将液体注入到通过其引入液体的进料口或装配到移液管的移液管尖端上，该附件包括管状附接体，其在其远端具有液体出口并且在其近端处具有插入口，所述移液管的远端部分或所述移液管末端插入所述插入口中; 以及由设置在附接体的液体出口周围的橡胶状弹性体形成的垫圈。
