摘要： A milk weight metering apparatus (10) is disclosed which uses a standard glass milk weigh jar (14) which is suspended from a load cell weight measuring unit (15). A hydraulic output line (16) extends from the weight measuring unit (15) to a pressure transducer (17) at a position remote from the cow being milked, preferably outside the milking parlor. As milk accumulates within the milk weigh jar (14) greater pressure is provided on fluid sealed within a chamber defined by a load cell body (55) and a diaphragm (63), which pressure is transmitted through the hydraulic line (16) to the pressure transducer. The change in weight of the suspended weigh jar (14) after the milk has been accumulated therein will be proportional to the change in the pressure in the hydraulic line (16), allowing the weight, and thereby the volume, of the milk from the cow to be determined and recorded. The production from the cow may also be correlated with the cow's identity and the time of milking.
摘要翻译： 公开了一种使用从称重传感器重量测量单元（15）悬挂的标准玻璃奶称重罐（14）的奶重计量装置（10）。 液压输出管线（16）从重量测量单元（15）延伸到压力传感器（17），位于远离被挤奶的母牛的位置，优选在挤奶室外。 当牛奶积聚在牛奶称重罐（14）内时，在由称重传感器体（55）和隔膜（63）限定的室内密封的流体上提供更大的压力，该压力通过液压管线（16）传递到 压力传感器。 牛奶在其中积聚之后的悬挂重量罐（14）的重量变化将与液压管线（16）中的压力变化成比例，从而允许牛奶的重量，从而允许来自 牛被确定和记录。 牛的产量也可能与牛的身份和挤奶时间相关。

摘要： An ocular irrigation device including an engaging member engageable with an eyelid to hold the eyelid open, a source of fluid, and a fluid dispenser operatively associated with the source of fluid and slidably connected to the engaging member. The fluid dispenser is arcuately-shaped and has a plurality of fluid-dispensing orifices positionable under an eyelid to provide fluid directly under the eyelid at multiple arcuately-spaced locations. The engaging member includes a wire formed into an arcuate portion that is positionable under an eyelid. The fluid dispenser is positionable in spaced relation relative to the engaging member such that the engaging member can engage and hold one eyelid open and the fluid dispenser can engage and hold the opposing eyelid open. The fluid dispenser includes an opening for allowing visual and/or physical access to the eye when the orifice is positioned under the eyelid. The sliding member can include raised portions for improving frictional engagement with the sliding member.
摘要翻译： 一种眼睛冲洗装置，其包括可与眼睑接合以保持眼睑打开的接合构件，流体源和与流体源可操作地相关联并可滑动地连接到接合构件的流体分配器。 流体分配器是弧形的并且具有可定位在眼睑下方的多个流体分配孔，以在多个弧形间隔位置处直接在眼睑下面提供流体。 接合构件包括形成为可在眼睑下方定位的弓形部分的线。 流体分配器可相对于接合构件定位成间隔的关系，使得接合构件可以接合并保持一个眼睑打开，并且流体分配器可接合并保持相对的眼睑打开。 流体分配器包括开口，用于当孔口位于眼睑下方时允许眼睛和/或物理接近眼睛。 滑动构件可以包括用于改善与滑动构件的摩擦接合的凸起部分。

摘要： A catheter assembly is provided to facilitate taping of the emplaced catheter onto the patient's body. The assembly comprises a catheter extending distally from a catheter hub. The hub has a hub axis co-axially aligned with the catheter and provided with a pair of opposed wings integral with the hub. Each of the wings having a proximal edge and a distal edge are such that a portion of at least one of these edges forms an acute angle with the axis of the hub of from about 35.degree. to about 55.degree. whereby the taping operation of the wings to the patient's body may be facilitated.
摘要翻译： 提供导管组件以便于将放置的导管贴到患者身上。 组件包括从导管毂向远端延伸的导管。 轮毂具有与导管同轴对准的轮毂轴，并且设置有与轮毂一体的一对相对翼。 具有近侧边缘和远侧边缘的每个翼片使得这些边缘中的至少一个边缘的一部分与轮毂的轴线形成约35°至约55°的锐角，由此翼部的带状操作 可以方便患者的身体。

摘要： A needle spacer is disclosed for use with a biopsy needle assembly of the type which is coupled to a driving unit to effect movement of the needle assembly. The needle spacer maintains the biopsy needle assembly in a predetermined operational relationship until after the needle assembly is coupled to the driving unit. In the preferred embodiment, the needle spacer prevents the lid of the driving unit from being closed while the needle spacer is still in place on the needle assembly, thereby eliminating the possibility that the physician will forget to remove the spacer prior to firing the instrument. In a first alternate embodiment, the needle spacer is configured to interfere with movement of the needles within the driving unit while the spacer is still in place so that if the physician attempts to fire the instrument with the needle spacer still in place, the needles will not advance. In a second alternate embodiment, the needle spacer includes a readily visible flag which, even with the lid of the driving unit closed, will alert the physician that the needle spacer is still in place, thus reducing the possibility that the physician will forget to remove the spacer.
摘要翻译： 公开了一种用于与活检针组件一起使用的针间隔件，所述活检针组件联接到驱动单元以实现针组件的移动。 针间隔件将活检针组件保持在预定的操作关系中，直到针组件联接到驱动单元。 在优选实施例中，针间隔物防止驱动单元的盖子闭合，同时针间隔件仍然在针组件上的适当位置，从而消除了在点燃仪器之前医生将忘记移除间隔件的可能性。 在第一替代实施例中，针间隔件构造成在间隔件仍然在位的同时干扰针在驱动单元内的运动，使得如果医生试图用针间隔物仍然在位的方式点燃器械，则针 不推进 在第二替代实施例中，针间隔件包括容易看到的标志，即使在驱动单元的盖关闭的情况下，该标记将警告医生针间隔件仍然在位，从而减少医生将忘记移除的可能性 间隔物。
