摘要： To prevent damage to a tube in a roller pump which pumps a fluid contained in the tube by squeezing it against an inner wall surface of a housing with a roller, so that the tube can be used continuously for a long time. A depression which a part of the tube enters when squeezed with the roller is formed on at least one of a roller surface of the roller and the inner wall surface of the housing. This alleviates a load on the tube, thereby preventing damage to the tube. Alternatively, the roller may include a plurality of disc rollers that are separately rotatable. This reduces differences in frictional force acting upon the tube when squeezed by the roller, thereby preventing damage to the tube. According to these constructions, the tube can be used continuously for a long time.
摘要翻译：为了防止滚筒泵中的管子受到损坏，该滚筒泵通过用滚筒将其挤压在壳体的内壁表面上来泵送容纳在管子中的流体，使得管子可以连续使用很长时间。当滚筒挤压时，管的一部分进入的凹陷形成在滚筒的辊表面和壳体的内壁表面中的至少一个上。这减轻了管上的负载，从而防止损坏管。或者，所述辊可以包括可单独旋转的多个盘辊。这减小了当被辊挤压时作用在管上的摩擦力的差异，从而防止损坏管。根据这些结构，该管可以连续使用很长时间。

摘要： A weight measuring apparatus can ensure safety even if a trouble or deterioration of measurement accuracy occurs.
The weight measuring apparatus (10) measures a weight of fluids for blood purification and includes the followings. A first arm (110) has a first fitting (111) to fit a supply fluid container (20). A second arm (120) is connected to the first arm (110) and has a second fitting (121) to fit a filtrate container (30). A third arm (130) is connected to the second arm (120). A first measuring device (220) measures, as a first total weight, a total weight of the supply fluid container (20) and the filtrate container (30) based on a change of the second arm (120). A second measuring device (230) measures, as a second total weight, the total weight based on a change of the third arm (130). An alarm (300) alarms, when the first and second total weights have different values having a difference equal to or greater than a predetermined value.

摘要： In a rotor of a conventional tube pump, a spring mechanism for absorbing pulsations or loads is made to match only either of rotational directions. The case, in which the tube pump is used in the direction opposite to the matched rotational direction, is limited to the case, in which large pulsations may occur. The spring mechanism has a low load-absorbing effect thereby to make it difficult to run the tube pump for a long time. The long-time run could be attained if the housing or motor were strengthened, but this strengthening raises the cost. A tube pump rotor of the present invention comprises a rotor element (2), a plurality of first swing portions (4a) supported pivotally at their base end portions by the rotor element (2), second arm-shaped swing portions (4b) supported pivotally at their base end portions individually by the first swing portions (4a), rollers (6) supported rotatably by the individual free ends of the second swing portions (4b), and buffer members ( 7a to 7 ) made to confront the side faces of the second swing portions (4b) so that the rollers (6) may be individually directed radially outward of the rotor (2).
摘要翻译：在常规管式泵的转子中，用于吸收脉动或负载的弹簧机构仅使旋转方向相匹配。其中管泵在与匹配的旋转方向相反的方向上使用的情况被限制在可能发生大的脉动的情况。弹簧机构具有低负载吸收效果，从而使得难以长时间地运行管式泵。如果住房或电机得到加强，可以实现长期运行，但这种加强会增加成本。本发明的管式泵转子包括转子元件（2），多个第一摆动部分（4a），其通过转子元件（2）枢转地支撑在它们的基端部，第二臂状摆动部分（4b）被支撑由第一摆动部分（4a）和第二摆动部分（4b）的各个自由端可旋转地支承的滚子（6）以及与侧面相对的缓冲部件的第二摆动部分（4b），使得辊（6）可以分别指向转子（2）的径向外侧。

摘要： A state detecting device can efficiently remove air bubbles from a liquid no matter whether the liquid flows forwards or backwards. The state detecting device (1) is provided in a tube to detect a state of a liquid flowing in the tube. The state detecting device (1) includes: a liquid hold part (2) in which the liquid is stored; an inflow part (4) from which the liquid enters the liquid hold part (2); an outflow part (5) from which the liquid exits from the liquid hold part (2); an inlet (8) that is a rear end portion of the inflow part (4); and an outlet (9) that is a front end portion of the outflow part (5). Here, the inlet (8) and the outlet (9) are arranged higher than a center of the liquid hold part (2) in a vertical direction when the state detecting device is provided in the tube.
