摘要： A system for securing a blood separator bowl in an autotransfusion machine includes a split ring or collar adapted to grip an enlarged cap on the base of the bowl and a clamp assembly for moving the collar between retracted and expanded positions. In the retracted position, the clamp assembly includes both an overcenter lock system for securing the collar in the retracted position and a backup auxiliary lock in the event of failure. The system further provides for centering the separator bowl on its axis of rotation to prevent undue vibration.

摘要： A peristaltic pump and tube body system disclosed includes a pump housing, a pump rotor rotatably mounted in the housing, and a motor for driving the rotor. The housing has a pair of opposed side walls hinged and releasably latched to the housing whereby insertion and removal of a pump tube is facilitated. The rotor has two rollers disposed at 180 degrees to one another together with opposed rigid bearing surfaces inside the housing which squeeze the latch to produce a pumping action when the rotor is rotated in either direction.

摘要： The present invention is a blood separation system that is fully mechanized to collect blood from a patient, separate waste portions of the blood, wash the blood, and redirect the usable portions to a device for reinjecting the usable portions into the patient. The present invention prevents accidental activation of an improper operation that could cause harm to a patient or a shut down of the system by requiring confirmation of each step by an operator. The invention provides screen displays with detailed setup instructions, eliminating the need for secondary documentation that might not be allowed in a surgical environment. The invention also instructs the operator at the appropriate times to do certain manual steps such as opening and closing clamps. Since the opening and closing of clamps is a highly critical operation, confirmation of these steps is also required. A method and suitable apparatus is also disclosed for sequestration of platelet rich plasma whereby a blood sample is spun at a high speed sufficient to separate solid cells from the blood sample and spun at a lower speed for a predetermined time to allow platelets to elute from the solid cells.
摘要翻译：本发明是一种血液分离系统，其完全机械化以从患者收集血液，分离血液的废物部分，洗涤血液，并将可用部分重定向到用于将可用部分再注入患者体内的装置。本发明通过要求操作者确认每个步骤来防止意外激活可能对患者造成伤害或系统关闭的不当操作。本发明提供具有详细设置说明的屏幕显示，消除了在手术环境中可能不允许的辅助文档的需要。本发明还在适当的时候指示操作者进行诸如打开和关闭夹具的某些手动步骤。由于夹具的开启和关闭是非常关键的操作，因此还需要确认这些步骤。还公开了一种用于螯合富含血小板血浆的方法和合适的装置，其中血液样品以足以从血液样品分离固体细胞并以较低速度纺丝预定时间的高速旋转以允许血小板从固体细胞。

摘要： The present invention is a centrifuge bowl housing and cover latch suitable for use in a blood separation system. The housing is mounted on shock absorbers to minimize transmission of vibrations from the centrifuge. The housing is configured to retain spilled liquids, efficiently collect the spilled liquids, drain liquids away from the drive means, and drain liquids out of a drain port to a collection container. The housing has a transparent cover that opens to allow loading of centrifuge bowls into the housing. The cover is a shatter resistant material and when closed, seals the top of the housing, retaining blood components and flying pieces of a centrifuge bowl if the bowl breaks. The cover has a latch that prevents the centrifuge from spinning when the cover is open and prevents opening of the cover when the centrifuge is spinning.

摘要： The disposable flexible pouch for collecting and filtering blood has two inner chambers separated from each other by a filtering screen (11), a first chamber being connected to the outside by an outlet opening for the filtered blood and a second chamber being connected to the outside by an inlet opening for the blood to be processed. The pouch is formed from two superposed walls (1, 2) made of a flexible plastic material and bonded together by welding of their respective peripheral edges (3). The inlet and the outlet openings for the blood, as well as an outlet opening (5) for the suction air provided with a bacterial filter, are all made in the same wall (2) forming the pouch and the filtering screen (11) having a lower surface at the surface of this same wall (2) cooperates with the inner face thereof to form several compartments communicating with one another and forming the second chamber, so that the retention volume is reduced.

摘要： A pinch clamp finding a primary use in an autotransfusion machine includes a hollow clamp head having a closed upper end and an open lower end reciprocally receiving a piston. A lateral groove is established in the clamp head so that a deformable tube can be received in the clamp head passing through the hollow interior thereof. The piston is reciprocally moved within the clamp head so as to selectively pinch the tube between the piston head and the closed end of the clamp head. The piston is positively reciprocated by cam followers on a piston rod with the cam followers riding in closed cam tracks in adjacent cam wheels on opposite sides of the piston. The cam wheels are mounted on a crankshaft which is selectively driven by power means.
