摘要： A fluid flow control device (10) which is employed in conjunction with a fluid pump (12) and which functions to restrict reverse flow of liquid which is induced by the fluid pump to flow in a forward direction through the device from a source (11) of the liquid. The device comprises a housing (20 or 50) which contains first and second chambers (21 and 22 or 51 and 52), and a tube (26 and 37 or 54 and 60) is located in each of the chambers. Thetubes (26,37, 54 and 60) define fluid passageways (27, 36, 55 and 61) through which the liquid is induced to flow in passing into the respective chambers (21, 22, 51 and 52), and the tubes extend upwardly through the respective chambers to a level above the level of liquid which is contained in the chambers. Valve members (30,39, 59 and 63) are located at the upper end of the respective tubes (26,37, 54 and 60), the valve members providing for forward flow of liquid into the chambers from the respective tubes and serving to prevent the liquid from leaking in a reverse direction along the fluid passageways (27,36,55 and 61 A control port (32 or 64) enters the housing (20 or 50) and is connectable to the fluid pump (12) for the purpose of applying alternating negative and positive pressurisation to the chambers whereby the liquid is induced to flow into and through the chambers.

摘要： A reciprocating pump for dispensing fluent substances comprises a piston (218) mounted on the end (219) of a piston rod (217) reciprocable in a pumping chamber (210) refilled from a container (213) through a clearance (225). The piston rod is slidable in a guide tube (214) opening out of the end wall (212) of the pumping chamber. In non-operated position the piston rod seals (at 120) with the wall of the guide tube (at 124) adjacent the end wall of the chamber. During the pumping stroke fluid displaced from the chamber (210) by the descending piston (218) passes between the piston rod (219) and the guide tube (214) to an outlet (215, 216).

摘要： A pipetting and dosing device, in particular for use in automatic clinical analysis apparatuses, for dosing and dispensing accurate liquid volumes, such as samples and reagents, comprises an internally cylindrical suction pipe (5) with a conically tapering distal end (17) with a central opening (18), a piston (7) axially movable within the suction pipe while sealing against the inner wall of the pipe, and drive means (8-13) for moving the piston axially over well-defined distances in the suction pipe for, respectively, sucking up and discharging predeterminable volumes of liquid. The end of the piston facing the conically tapering distal end (17) of the suction pipe (5) is provided with a conical tip (7a) having an apex angle somewhat larger than the apex angle of the coni cally tapering end of the suction pipe and this conical piston tip (7a), or alternatively the conically tapering end (17) of the suction pipe, is made of a resiliently deformable material. At the end of the discharge movement of the piston in the suction pipe the conical tip (7a) of the piston is moved into abutment against the conically tapering end (17) of the suction pipe with such an axial force that, through elastic deformation of the piston tip or alternatively the conically tapering end of the suction pipe, the piston tip and the conically tapering end of the suction pipe are brought into complete conformity without any residual interspace remaining therebetween.

摘要： Embodiments described herein generally relate to devices, systems and methods for measuring a volume or number of doses remaining in a drug delivery device that is used for delivering a dose to a patient. In some embodiments, a dose measurement system for measuring the liquid volume in a container includes a light guide disposed and configured to reflect electromagnetic radiation toward the container. The dose measurement system also includes a light guide disposed and configured to emit electromagnetic radiation into the light guide. A plurality of sensors are located in the apparatus that are optically coupleable to the light guide and are disposed and configured to detect the electromagnetic radiation emitted by at least a portion of the light guide. The apparatus also includes a processing unit configured to receive data representing the portion of the detected electromagnetic radiation from each of the plurality of sensors. The processing unit is further operable to convert the received data into a signature representative of the electromagnetic radiation detected by the plurality of sensors.
