Description
【特許請求の範囲】
【請求項１】 所定位置に配置される容器から液体を吸引する液体吸引装置において、
先端が鋭利形成され液体を吸引することができる液体吸引管と、
液体吸引管を保持し上下方向に移動する第１の保持部と、
第１の保持部を上下移動させるための力を提供する第１の駆動源と、
第１の保持部と係合しこれを押圧し上下方向に移動する第２の保持部と、
第２の保持部を上下移動させるための力を提供する第２の駆動源と、
上記これら手段を制御する制御手段と、を備え、
制御手段は、栓体なしの容器に対しては第１の保持部を第２の保持部と係合させずに第１の駆動源の力によって上下移動させ、栓体ありの容器に対しては第１の保持部を第２の保持部と係合させて第２の駆動源の力によって上下移動させるよう制御することを特徴とする液体吸引装置。
【請求項２】 第１の駆動源の力により液体吸引管が容器に向かって移動したときに液体吸引管に上向きの外力が作用したことを検知する外力検知手段と、液体吸引管先端部分が液面に到達したことを検知する液面検知手段を備え、
制御手段は、上記外力が検知されなかった場合、液面検知手段による液面検知情報又は外力検知手段による外力検知情報に基いて第１の駆動源を停止させ、上記外力が検知された場合、液面検知手段による液面検知情報に基いて第２の駆動源を停止させることを特徴とする請求項１記載の液体吸引装置。
【請求項３】 液体吸引管の管先端に斜めカット面が形成され、その斜めカット面における管内壁端に鋭角エッジが生じないよう構成されてなることを特徴とする請求項１記載の液体吸引装置。
[Claims]
1. In a liquid suction device that sucks a liquid from a container arranged at a predetermined position.
A liquid suction tube with a sharp tip that can suck liquid,
The first holding part that holds the liquid suction tube and moves in the vertical direction,
A first drive source that provides a force to move the first holder up and down,
A second holding part that engages with the first holding part and presses it to move in the vertical direction,
A second drive source that provides a force to move the second holder up and down,
A control means for controlling these means is provided.
The control means moves the first holding portion up and down by the force of the first drive source without engaging with the second holding portion for the container without the plug, and for the container with the plug. Is a liquid suction device characterized in that the first holding portion is engaged with the second holding portion and controlled to move up and down by the force of the second drive source.
2. An external force detecting means for detecting an upward external force acting on the liquid suction tube when the liquid suction tube moves toward the container by the force of the first drive source, and a tip portion of the liquid suction tube. Equipped with a liquid level detection means to detect that the liquid level has been reached,
When the external force is not detected, the control means stops the first drive source based on the liquid level detection information by the liquid level detection means or the external force detection information by the external force detection means, and when the external force is detected, the control means stops the first drive source. The liquid suction device according to claim 1, wherein the second drive source is stopped based on the liquid level detection information by the liquid level detecting means.
3. The liquid suction according to claim 1, wherein an oblique cut surface is formed at the tip of the liquid suction tube, and an acute-angled edge is not generated at the end of the inner wall of the tube on the oblique cut surface. apparatus.
