A system includes a durable portion with a durable housing and a separable disposable portion with a disposable housing that selectively engage with and disengage from each other. The disposable housing secures to a patient and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient or with an infusion medium may be part of the disposable portion to allow for disposal after a prescribed use. A reservoir for holding the infusion medium may be part of the disposable portion, and may be supported by the disposable housing. The durable portion may include other components such as electronics for controlling delivery of the infusion medium from the reservoir, and a drive device including a motor and drive linkage.

An accommodating intraocular lens includes an optic portion, a haptic portion. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles and a secondary deflection mechanism. Movement of the lens element by the actuator causes the lens element to deform and the secondary deflection mechanism causes the lens to further deform.

A medical valve has a translating member that enlarges the volume of the interior of the valve when the valve is in an open mode (permitting fluid flow), and decreases the volume of the interior when the valve is in a closed mode (preventing fluid flow). This varying volume should substantially eliminate drawback into the valve. To that end, the valve includes a housing having an inlet and an outlet, and a fluid channel extending between the inlet and the outlet. The fluid channel includes a variable volume region. The valve further includes the above noted translating member, which is secured to the housing and at least partly bounds the variable volume region. The translating member has at least a portion that moves distally when the valve transitions from the closed mode to the open mode. The distal movement of the translating member enlarges the volume on the variable volume region.

An accommodating intraocular lens includes an optic portion a haptic portion and a backstop. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. The backstop provides support to the haptic so that bulk translation of the haptic is prevented in response to the forces applied by the capsular sac.

In a mixing pump device (1), during an suctioning step a stepping motor (12) rotates in a first direction, so that during this time, a plurality of fluids can be drawn in prescribed proportions into a pump chamber (2), by sequentially opening and closing active valves (5a, 5b) situated in inflow passages (3a, 3b) while active valves (6a, 6b) situated in outflow passages (4a, 4b) are in a closed state. During the discharging step the stepping motor (12) rotates in a second direction, so that during this time, a mixed fluid can be discharged from the pump chamber (2) simply by sequentially opening the active valves (6a, 6b) situated in the outflow passages (4a, 4b), while the active valves (5a, 5b) situated in the inflow passages (3a, 3b) are in a closed state. It is possible thereby to achieve a mixing pump device capable of mixing a plurality of fluids in prescribed proportions, without detecting the operating stage of the pump.

A control unit for use in a window blind head rail assembly including a system of transfer gears coupled to a driving member, the transfer gear system comprising a rotatable inner ring gear; one or more intermediate gears having fixed positions relative to the sprocket support and being rotatable about their own axes; a rotatable outer ring gear connected to a driven member; wherein rotation of the inner ring gear causes rotation of the one or more intermediate gears about their own axes, which causes rotation of the outer ring gear. The driving member has a driving pulley so that force applied to the driving member will cause rotation of the driving pulley and then the gears. A sprocket support and braking means to prevent the control unit from rotating other than in response to force applied via the driving member are also essential as is a splined bush.

A device and method for producing a portion of platelet rich plasma from a fluid sample obtained from a patient. The device comprises three intercommunicated portions, each portion having an internal chamber defined therein. The fluid sample is first brought into the base portion where it is separated into red blood cells and plasma. The plasma portion of the sample is then withdrawn into the second portion where it is further separated into platelet poor plasma disposed over platelet rich plasma. The portion of platelet poor plasma is then withdrawn from the second chamber, leaving only platelet rich plasma within the second chamber. The base portion also includes a membrane located on its distal end which helps maintain a vacuum within the device when the fluid sample is being initially inserted into base chamber.
