摘要:
The invention relates to a diffuser (1), comprising a substantially cylindrical, vertical container (2), through which cellulose pulp is arranged to be transported, nozzle arms (6, 7) for delivering a fluid, such as washing liquid, to the pulp, concentrically disposed screen surfaces (3, 4) and screen arms (5) disposed on and connected to the said screen surfaces for withdrawal of the said fluid. The screen arms are provided, at their outer ends, with withdrawal pipes (26), directed substantially vertically downwards, which are slidably controlled and are connected in sealing arrangement to outlets for the said fluid. The invention relates also to a stuffing box designed to receive a rod, preferably a pull rod (29) for raising and lowering a screen pack having screen surfaces (3, 4) in a diffuser, the said rod being guided in sealing arrangement and slidably through a fixture (35; 35') which is mounted in a bearing for free movement in a plane substantially perpendicular to the said rod. The bearing comprises a radially directed bearing flange (44; 44') extending around the said fixture, which bearing flange is mounted between two radially directed retaining flanges (39, 42; 39', 42') extending around the said fixture.
摘要:
A device for discharging particulate material from a container with a table to support the particulate material includes a feed unit which is movable on the table for discharging the material through a peripheral outlet opening, and a drive for driving the feed unit; the feed unit includes at least two spaced feeding elements disposed to successively move the material in a direction from the center of the table towards the outlet opening; the feeding elements are arranged, during a full cycle of movement of the feed unit, to be alternately active within an arbitrary section of the table extending between the center part and outlet opening for feeding a layer of particulate material in front of them in the direction toward the outlet opening and inactive while returning to a starting position.

An integrated blood treatment module comprises a blood treatment device (1) having a housing (2) and a first end-cap (4) and a second end-cap (5) closing both ends of the housing (2). A pump hose (17) for a peristaltic pump has a first end (18) that is secured to the housing (2) and a second end (16) that is connected to a blood inlet port (15) of the first end-cap (4) so as to form a loop. A degassing device (30) is connected to the second end-cap (5). The degassing device (30), which, in use, is full of liquid, comprises a hydrophobic membrane through which bubbles and micro-bubbles escape the degassing device.
摘要:
An optical fibre through which light passes is used for detecting blood leakage from a wound. The fibre may be comprised by a blood leakage detection apparatus having a light source and a photo detector in radiative communication with the respective ends of the fibre and producing an electrical signal in response to the light detected, photo detector signal amplifying means, means for detecting changes in the amplified signal over time, and alarm means, wherein a decrease in signal strength during a selected time period activates the alarm means; a corresponding method of detecting blood leakage; a device for use with the apparatus of the invention comprising the optical fibre thereof provided with coupling means at its ends and a patch of blood absorbing material.
摘要:
A device for preparing a sterile liquid includes structure for validating a sterilization treatment applied to the liquid. The validating structure includes structure for calculating, from at least one operating parameter of the device, a parameter representing a sterilizing value for the sterilization treatment, and structure for comparing the calculated parameter to a threshold value corresponding to the sterility of the liquid.
摘要:
Apparatus for the preparation of fluids intended for medical use is disclosed, including a water source and at least one cartridge or other vessel containing a solid such as a powder which is to be dissolved in the water for preparation of the desired fluid. The apparatus includes a container such that the water and a powder can be mixed and a concentrate provided in the container, and a recirculation circuit for recirculation of the water or concentrate solution into the container for further mixing of the water and powder to prepare a concentrate having a predetermined concentration.
摘要:
Apparatus for the preparation of fluids intended for medical use is disclosed, including a source of pure water and at least one cartridge or other vessel containing a powder which is to be dissolved in the water for preparation of the desired fluid. The apparatus includes a container such that the water and a powder or powder concentrate can be mixed and a concentrate provided in the container, and a recirculation circuit for recirculation of the water or concentrate solution into the container for further mixing of the water and powder or powder concentrate to prepare a concentrate having a predetermined concentration.
摘要:
The present invention relates to a tightening device for cone belts and the like for use in cone belt transmissions, including at least one preferably driven cone belt pulley which is axially or substantially axially displaceable relative to at least one other, preferably driven cone belt pulley, and a cone belt interconnecting said cone belt pulleys, said tightening device engaging one run of the cone belt by means of a rotary member.The novelty of the invention is that the tightening means includes a preferably spring-loaded support lever arranged adjacent one of the cone belt pulleys and adapted to pivot about a first axis situated substantially parallel with the cone belt pulley shaft and also about an axis oriented generally perpendicular to the first axis, and that a tightening pulley preferably provided with a cone belt groove is fitted at a free end of said support lever in order to maintain the engagement of the tightening pulley independently of any displacement of the cone belt runs caused by the relative displacement of the cone belt pulleys.
摘要:
A cartridge configured to be connected to a blood treatment apparatus, the cartridge including a cartridge inlet, a cartridge outlet and chambers each of which is configured to hold a concentrate in powder form. A flow controller is configured to provide a flow passage from the cartridge inlet to a single selected chamber of the chambers and from the single selected chamber to the cartridge outlet. The flow controller is movable between a plurality of positions, such that a position of the flow controller defines which of the plurality of chambers is the single selected chamber.
摘要:
The invention relates to a multi-ports extracorporeal medical device (1) having a selector body (19) which can be linearly displaced within the housing (16) in order to create different flow paths and connection among the ports. The device can for instance be used for reversing the flow in an extracorporeal blood circuit.
