Abstract: Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.

Abstract: A trigger has a body, two adjusting buttons, a connecting shaft, a pressing tab and a torsion spring. The body has a back, two sidewalls and two elongated slots. The adjusting buttons are slidably mounted respectively in the elongated slots and are connected to each other with the connecting shaft. The pressing tab is rotatably mounted around the connecting shaft and has a connecting segment, a first pressing segment and a second pressing segment. The first pressing segment is formed on and protrudes from the connecting segment and has a first distance to the back of the body. The second pressing segment is formed on and protrudes from the first pressing segment and has a second distance to the back of the body being different from the first distance of the first pressing segment.

Abstract: An adjusting device for a nail gun includes a magazine, a shaft, a disc feeder and a positioning assembly. The shaft is mounted in the magazine and has two sliding grooves longitudinally formed respectively in the shaft and multiple positioning recesses formed on the sliding grooves. The disc feeder includes a rotating disc and a sleeve mounted around the shaft and has two mounting holes each corresponding to a positioning recess. The positioning assembly includes a clamp and an E-clip having two stops. The clamp is mounted in the sleeve and has two clamping arms each having a boss. The stops are mounted respectively in the mounting holes, respectively abutting the clamping arms and held by the E-clip. Therefore the magazine can be adjusted in one direction at multiple stages by pulling up and in the other direction by pressing the clamp that releases the stops for easy adjustment.

Abstract: A magnetic-tipped piston for a nail gun has a piston head, a driving rod and a magnet. The piston head has a connecting hole. The connecting hole is formed axially through the piston head. The driving rod is connected securely to the piston head and has a connecting end and a driving end. The connecting end is mounted securely in the connecting hole of the piston head. The driving end is formed on and protrudes axially from the connecting end to eject nails out of the nail gun and has a mounting recess. The mounting recess is formed axially in the driving end. The magnet is mounted securely in the mounting recess of the driving rod to attract and hold a head of the nail.

Abstract: A nail gun has a body, a breach assembly, a triggering device, a safety assembly and a magazine. The safety assembly has a safety lever and an activating beam, both of which are required to be activated to selectively engage the triggering device to allow the nail gun to perform a nailing cycle. When the nail gun is operated incorrectly, the safety assembly does not engage the triggering mechanism so the nail gun is prevented from performing the nailing cycle. The magazine is mounted in the breach assembly and feeds fastening devices into the breach.

Abstract: A piston assembly for a staple gun has a piston head, a driving rod and a fastener. The piston head has a connecting post formed on and protruded axially from a top of the piston head and having two mounting blocks and an inserting recess. Each mounting block has two indents and two holding tabs. The inserting recess is defined between the inner sides of the mounting blocks, and the holding tabs extend into the inserting recess. The driving rod is connected securely with the piston head and has a body, a connecting segment and a driving segment. The connecting segment is mounted and held in the inserting recess and is engaged firmly with the holding tabs. The driving segment is formed on the upper end of the body to press staples out of the staple gun. The fastener is connected with the driving rod and the piston head.

Abstract: A nail gun has a gun body, a muzzle and a spring. The muzzle is pivotally mounted on the gun body. The muzzle has a top case, a bottom case, a first pin and a second pin. The top case and the bottom case both have an engaging part and the top case and the bottom case are connected with each other by the engaging parts. A channel is formed between the top case and the bottom case. The spring is mounted around the second pin and between the muzzle and the gun body. When the nail gun is in use, a nail passes through the channel, and the muzzle is pivoted to open around the pins and the engaging parts, therefore, the nail is applied with a balance force when passing through the channel to make the nail moving along a straight path.

Abstract: A belt of nails for nailers includes an outer belt, an inner belt and multiple nails. The outer and inner belts are parallel and respectively have multiple cylindrical outer and inner brackets connected in a straight line with connecting ribs between adjacent brackets. The outer and inner brackets respectively have axial outer and inner nail holes that are aligned. The nails have enlarged heads, shanks and tips. The shanks are mounted respectively through the outer nail holes, and the tips are mounted respectively inside the inner nail holes. Consequently, the outer and the inner belts securely hold the nails so the nailer will roof or nail perfectly.

Abstract: A belt of collated nails for use with an air-driven nailing gun is disclosed having a plurality of nails, a plurality of flexible nail guide caps connected in series and respectively capped on the points of the nails and adapted to guide the nails into the workpiece, and a plurality of breakable flexible sockets connected in series and spaced above the flexible nail guide caps and adapted to hold the nails in the flexible nail guide caps, the breakable flexible sockets each having a through hole for receiving the nails respectively.

Abstract: A follow block structure of a magazine for stapling guns adapted for use in a fastener feed structure of a stapling gun, the magazine including a slide groove along which a follow block may slidably displace. The follow block includes a pull tab extending from one side thereof, a recess at a central portion thereof for mounting a slide element. The slide element is insertably fitted to the follow block to aid the follow block in slidable displacement along the slide groove to push fasteners forwardly. The slide element is made of engineering plastics so that there is a relatively small friction coefficient when it slides along the slide groove which is made of aluminum alloy. The slide element has good wear resistance and can ensure the smooth displacement of the follow block. Besides, the slide element can be easily and conveniently replaced when worn so that maintenance cost is reduced.

Abstract: A no-idle-striking structure for nailing machines including a strike assembly, a bumper bar, a magazine, and a follow plate. The bumper bar is provided with a hook which may extend into a magazine support. The follow plate has a stop portion. When there are nails in the magazine, the bumper bar is in normal state so that pulling of the trigger will cause a nail to be driven into a workpiece. But when the nails are used up, the follow plate will elevate to the position of the magazine support so that its stop portion will restrain the hook of the bumper bar from displacing rearwardly. As a result, pulling of the trigger will not effect any striking.
