A collapsing and securing device of a lateral blind includes a lateral blind such as a winding blind, a Roman blind, or a cloth blind, and a number of positioning members fixed at least on one surface of the window curtain, and the positioning members can temporarily adhere, stick or attract each other to secure the lateral blind at one of many collapsed position in case the lateral blind is manually wound up, without using pull ropes with a pool as used in a conventional lateral blind for preventing potential dangers involved in conventional lateral blinds. The collapsed lateral blind can be expanded down manually with easiness and quickness, with the temporarily adhered, stuck or attracted together positioning members separated from one another with easiness.

A cabinet safety device has a fixing base neighboring a side of the cabinet, a slide base mounted on the fixing base, lock members provided that can hook on both the slide base and the fixing base, and a fastening member provided between a bottom of the slide base and a bottom of the cabinet. When one of the drawers is pulled out, the slide base will go down to let the lock member escape from the slide base, and the slide base then goes up to prevent other drawers from sliding out, thus only one drawer can be pulled out at one time, which avoids potential danger when the center of gravity of the tool cabinet is shifted due to too many drawers being slid out at one time.

A portable hemodialysis system is provided including a disposable cartridge and a reused dialysis machine. The disposable cartridge includes a dialysate flow path and a blood flow path which flow in opposite directions through a dialyzer. The disposable cartridge further includes a filter for removing waste products from the dialysate as well as one or more flow sensors for measuring the flow of dialysate in the dialysate flow path. The preferred flow sensor includes a rotatable spoked wheel in the dialysate flow path which is rotated by the flow of dialysate. The spoked wheel includes one or more magnets which are rotated with the rotation of the spoked wheel. The flow sensor further includes a magnetic field sensor in the reused dialysis machine which is connected to a processor for monitoring the rotation of the spoked wheel to determine flow of fluid in the dialysate flow path.

A portable hemodialysis system is provided suitable for in home use. The hemodialysis system includes a disposable cartridge and a reused dialysis machine. The disposable cartridge includes a dialyzer, and a dialysate flow path and a blood flow path which flow in opposing directions through the dialyzer. In addition, the disposable cartridge possesses pump actuators (but not pump motors) for pumping dialysate and blood through their respective flow paths. The pump actuators having non-deformable components including a housing having a central cavity forming an internal sidewall, a rotor eccentrically positioned within the cavity having radially aligned slots at the rotor's periphery, and vanes slideably positioned in the slots to slide in and out of the slots so as to seal with the cavity's internal sidewall creating vane chambers that pump blood or dialysate.
