Description
- This application is a divisional of U.S. patent application Ser. No. 10/211,062 filed Aug. 2, 2002, which claims priority to U.S. provisional patent application No. 60/310,260 filed Aug. 6, 2001; the disclosures of which are incorporated herein by reference in their entireties.
- The present invention relates to the field of instrument treatment stations. More particularly, the present invention is directed to a serial wash station for microfluidic instruments.
- Present methods for cleaning arrays of microfluidic dispensing devices typically involve concurrent treatment of all the instruments at a single time. For example, the instruments are positioned in an ultrasound bath or in a pressurized manifold for washing all of the instruments at once. In the ultrasound baths, the array of instruments are simultaneously soaked in either a static or flowing bath of wash solution and then similarly rinsed or dried either at the same station or at other, specialized, stations. Such washing systems require copious amounts of wash fluid and of rinse fluid. Moreover, due to local variations of how the fluid acts upon the instruments, such washing systems do not provide a uniform treatment to each of the instruments in the array. Some of the instruments may thus receive a more thorough treatment than others within the array. Any non-uniformities in the treatment of the instruments may thwart the uniform performance of all of the instruments within the array.
- A pressurized manifold treatment station is sized to accept all of the instruments of the array within a sealed treatment chamber. The manifold typically seals itself against the array in a fluid-tight manner so that high pressure washing and rinsing fluids may be directed against the instruments without unacceptable leakage out from the chamber. The manifold may either provide a unique insertion orifice for each instrument in the array or a larger opening for accommodating all of the array therethrough. Such manifolds, however, are not scalable in that they may only accommodate an array of a single given dimension. Changes in the layout or number of instruments in an instrument array may require provision of a new treatment station tailored to the newly-shaped array. Moreover, pressurized manifolds do not provide a uniform treatment to all of the instruments of the array as the localized effects of the cleaning and washing may vary from instrument to instrument.
- The current methods or systems used for treating an array of instruments can therefore negatively impact upon the performance of the instruments when uniform performance is a premium desire. For example, non-uniform treatment of arrays of microfluidic dispensing devices may prevent the arrays from acceptably dispensing very small amounts of fluid samples in a microarray.
- In view of the foregoing, there is therefore a need in the art for an instrument treatment system which is able to accommodate an array of instruments and provide each like treatment.
- The present invention addresses these needs and more by providing an instrument treatment station which includes a station body having a first and second elongate and transversely-spaced channel walls. The channel walls define an elongate instrument channel therebetween. The station body defines an elongate drain channel in fluid communication with the instrument channel. The station body further defines a source port in fluid communication with the instrument channel for delivering a fluid flow into the instrument channel for treating an instrument therein. The instrument treatment station is scalable in that it may accommodate arrays of aligned instruments directed therethrough.
- The present invention further provides a method for treating a linear array of instruments comprising the steps of passing the array of instruments between a first and second elongate wall defining a wash channel therebetween, directing a wash fluid about at least a portion of each instrument of the array within the wash channel as the array passes through the wash channel, passing the array of instruments through a rinsing channel defined between another first and second elongate and transversely-spaced walls, and applying a means of rinsing to each instrument of the array within the rinsing channel as the array passes therethrough.

FIG. 1 , the present invention provides aninstrument treatment station 10 which can serially treat an array of instruments such as fluid dispensing devices.Treatment station 10 is desirably formed of plastic, acrylic, or any other material suitable for shaping and operation as a fluid treatment station of the present invention. It is contemplated thattreatment station 10 may either be fixedly mounted such that an array of instruments may be passed therethrough or movably mounted so as to pass over an array of instruments, so long as there is relative movement between the instruments and the treatment station.Treatment station 10 is scalable in that it may employed to treat any number of instruments within an instrument array while still providing a uniform treatment to each instrument of the array. The present invention is ideally suited for treating many different types of instruments including, for purposes of illustration and not of limitation, spotter pens, probes, cannulas, and syringes.Treatment station 10 may be configured to provide a variety of treatments to an instrument including, for purposes of illustration and not of limitation, washing, drying, coating, or the like. It is further contemplated thattreatment station 10 provide a unitary station for serially pre-drying an instrument, washing it with a first cleaning solution, washing it with a second cleaning solution, rinsing the instrument, and then drying the instrument. -

Referring now toFIGS. 2 and 3 ,station body 12 also defines a firsttreatment fluid passageway 20 extending in fluid communication between afirst channel port 22 defined bychannel wall 16 and afirst input port 24 defined bystation body 12 on a bottom surface thereof.Station body 12 also defines a secondtreatment fluid passageway 26 extending in fluid communication between asecond channel port 28 defined bychannel wall 16 and asecond input port 30 defined bystation body 12. Similarly,station body 12 further defines a thirdtreatment fluid passageway 32 extending in fluid communication between athird channel port 34 defined bychannel wall 16 and athird input port 36 defined bystation body 12. The spacing ofchannel walls channel ports channel wall 16 and thereby sufficiently envelop an instrument passing throughinstrument channel 18. - The present invention contemplates that first and
second channel ports instrument channel 18.Third channel port 34 is contemplated to provide a rinse fluid against an instrument passing therethrough so as to fully remove any excess wash solutions staying on the instrument.

As seen inFIGS. 4 and 5 ,drain channel 42 may be non-colinear withvacuum apertures passageways Station body 12 definesdrain ports instrument channel 18 anddrain channel 42. Drainchannel 42 conducts both ambient air and treatment fluids through the drain ports and away frominstrument channel 18. Drainports instrument channel 18 at locations to either side offirst channel port 22. Similarly,second channel port 28 opens intoinstrument channel 18 at a location betweendrain ports third channel port 34 opens intoinstrument channel 18 at a location betweendrain ports Treatment station 10 is desirably connected with a low pressure or vacuum line, not shown, atapertures instrument channel 18 through the drain ports and intodrain channel 42. The present invention, however, further contemplates that the geometry ofinstrument channel 18 anddrain channel 42 may be configured to provide sufficient clearing of any wash and rinse solutions without the need for a low pressure line. - As seen in
FIGS. 1 and 2 ,channel walls transverse grooves instrument channel 18. Each pair of opposing grooves are located adjacent to drainports outside treatment station 10 and any treatment fluids ininstrument channel 18 through the drain ports so as to be conducted away throughdrain channel 42 to a waste reservoir or drain as appropriate. The present invention contemplates that as an instrument to be treated passesgrooves grooves instrument channel 18 anddrain ports grooves - With reference now to
FIGS. 2, 3 , 5, and 6,treatment station 10 includes a means for mounting to a mounting surface, not shown. Desirably, the mounting means include a first andsecond pin 71 and 72 for aligning the station within tapped holes on a mounting surface, not shown.Station body 12 also defines a first and secondtransverse fastener passageway station 10 to the mounting surface. All apertures, passageway, and channels of the present invention are desirably machined by conventional methods well-known in the fabrication arts. For example, as shown inFIG. 5 ,passageway 32 may be drilled through thebottom surface 78 ofstation body 12 up intochannel wall 14.Channel port 34 is formed by drilling throughchannel wall 16 intochannel wall 14 until reachingpassageway 32. A sealingplug 80 is then inserted intochannel wall 16 to prevent leakage and thereby restorechannel wall 16. - The present invention therefore provides for the serial treatment of the instruments of an instrument array. A row of instruments may be passed through
instrument channel 18 to be serially pre-dried by air being drawn throughdrain ports channel port 22, washed with a second wash solution fromchannel port 28, rinsed with a rinsing solution fromchannel port 34, and dried by air drawn throughinstrument channel 18 bydrain ports instrument channel 18 prior to proceeding therethrough. -
Treatment station 10 thereby provides a scalable means of serially treating any number of instruments in a like manner. Should the number of instruments in an array be changed,treatment station 10 may still accommodate the array. It is further contemplated that two or more treatment stations of the present invention may be employed to treat one or more rows of an array of instruments. While not perfectly providing like treatment to each instrument of an array, the particular application of the array may place greater emphasis on the increased speed of processing more than one row of instruments at a time.
