The utility model discloses a flat sheet membrane assembly with a plug-in type cluster combination modular structure, which preferably comprises a hollow flat sheet membrane assembly body, an upper connecting piece, a lower connecting piece, a rubber division bar, a groove-shaped plate and an O-shaped sealing ring, a plurality of hollow flat diaphragm assemblies with the same specification are arranged in parallel at intervals along the thickness direction of the hollow flat diaphragm assemblies to form a group, the upper ends of the hollow flat diaphragm assemblies are inserted into holes of the upper connecting piece and are detachably connected in parallel through O-shaped sealing rings, and the lower ends of the hollow flat diaphragm assemblies are embedded into the lower connecting piece through rubber division bars to be detachably connected in parallel; groove-shaped plates are symmetrically embedded in the side faces between the upper connecting piece and the lower connecting piece, and detachable connection is formed, so that a plurality of hollow flat plate membrane assemblies are bundled into an integral combined structure. In a preferred second scheme, except for all the structures in the first scheme, the device further comprises a water collecting box connected to the upper connecting piece. The utility model provides two preferable schemes, so that the installation mode is more flexible, and the adaptability is stronger.

The application provides a five-axis rotary table of a rotary hydraulic device with an anti-overflow structure, which comprises a rotating shaft, a shaft sleeve and a workbench, wherein a positive pressure medium pipeline is arranged outside a high-pressure gas or high-pressure hydraulic oil pipeline of a first ring and a last ring, an opposite force acting on a high-pressure gas or high-pressure hydraulic oil annular sealing ring of the first ring and the last ring is applied, the high-pressure gas or high-pressure hydraulic oil can be discharged through the positive pressure pipeline, the high-pressure gas or high-pressure hydraulic oil is prevented from overflowing, and the five-axis rotary table is protected from being damaged, in addition, when the overflowing high-pressure gas or high-pressure hydraulic oil can be output through the positive pressure pipeline, the pressure sensor detects abnormal pressure and alarms, so that the damage of the high-pressure gas or high-pressure hydraulic oil annular sealing ring can be found in time, and the automatic clamping and positioning of a workpiece can be continuously and effectively used intelligently.

The invention relates to a peristaltic pump for conveying a fluid in a device for extracorporeal blood treatment, comprising a pump housing in which a rotor which can be rotated about a rotor axis is accommodated and which has at least two pressing elements which are offset from one another in the circumferential direction, the pump housing has a support surface extending in an arc shape about the rotor axis and spaced radially from the rotor, the support surface being provided for supporting a hose segment that can be introduced radially between the rotor and the support surface. The rotor carries the pressing element via a rocker arm, which is fixed on the rotor in a pivotal manner and in a spring-loaded manner. The rocker arm itself carries an introduction aid by means of which the hose segment can be pressed into the pump bed during the penetration thereof, and a hose guide element by means of which the hose segment can be oriented centrally relative to the pressing element. The rocker arm consists of high-strength stainless steel with high chemical stability and is produced in a powder injection molding process, preferably in a metal injection molding process.
