Abstract
Disclosed is a filling needle of a fluid-dispensing system, the filling needle including a needle portion that is a metallic material, a hub affixed to an end of the needle portion, wherein the hub is non-metallic and configured to securely associate with the fluid-dispensing system, and allow the fluid-dispensing system to be in fluid communication with the needle portion.
Description
- This Application claims the benefit of U.S. Provisional Application No. 60/903,178, filed Feb. 23, 2007, the contents of which are incorporated by reference herein in their entirety.
- The disclosure relates generally to a filling needle, and more particularly to a filling needle of a fluid dispensing system.
- Fluid dispensing systems typically include a reservoir, tubing, a pump or pumps, and filling needles. The reservoir contains a bulk supply of fluid for distribution to the other components of the system. Fluid is transported from the bulk supply to the pumps and/or needles via the tubing. The pumps then actuate dispensing of a desired amount of fluid into the filling needles, which in turn dispense the fluid into a desired container or onto a desired surface. These dispensing systems are often used in conjunction with containers that are moved into filling position (i.e. into proximity of the needles) via automated conveying devices. Automated conveyance of the containers or surfaces offers a quick and accurate means for dispensing fluid into multiple containers of a container batch.
- Despite this quickness and accuracy, dispensing systems can be costly to maintain, particularly in that the filling needles must be sterilized after a batch of containers is filled and/or before a new fluid is to be dispensed. Cleaning and sterilization of needles requires cleaning and sterilization equipment, as well as space to store the cleaning and sterilization equipment, which both can be costly. Needle cleaning and sterilization also increases down time between batch fillings, which prolongs the time it takes to fill (and ultimately ship) batches of different fluids.
- Furthermore, cleaning procedures must be developed and validated. These validation processes are time consuming and expensive. Cleaning and sterilization are also not failsafe. A company that relies on cleaning and sterilization of needles for re-use runs some risk of cross-contamination, associated health risks, litigation and adverse cost effects that can follow therefrom.
- Normally system tubing is fixed to the hub portion of the needle via friction or mechanical fasteners. Manufacturing the hub from a plastic or rubber provides the ability to permanently attach the system supply tubing to the needle hub.
- Accordingly, reduction or elimination of the costs and dangers associated with cleaning, cleaning validation and sterilization, as well as the costs associated with mechanical fasteners and adhesives, would be desirable.
- Disclosed is a filling needle of a fluid-dispensing system, the filling needle including a needle portion that is a metallic material, a hub affixed to an end of the needle portion, wherein the hub is non-metallic and configured to securely associate with the fluid-dispensing system, and allow the fluid-dispensing system to be in fluid communication with the needle portion.
- Also disclosed is a fluid dispensing system including a reservoir configured to hold bulk fluid, tubing that is fluidly communicable with the reservoir, and at least one filling needle, each of the at least one filling needles including a needle portion that is a metallic material and a hub affixed to an end of the needle portion, wherein the hub is non-metallic and configured to securely associate with the tubing, and allow the tubing to be in fluid communication with the needle portion.
- The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, like elements are numbered alike:
-
FIG. 1 is a planar view of an embodiment of a filling needle; -
FIG. 2 is a perspective view of dispensing end of the filling needle; -
FIG. 3 is a perspective view of receiving end of the filling needle; -
FIG. 4 is a perspective view of a fluid dispensing system; -
FIG. 5 is a planar view of a second embodiment of a filling needle; -
FIG. 5 a is a planar view of at least a portion of a hub of the second embodiment of a filling needle shown innFIG. 5 ; -
FIG. 6 is a planar view of a third embodiment of a filling needle; -
FIG. 7 is a planar view of a fourth embodiment of a filling needle; -
FIG. 8 is a planar view of a fifth embodiment of a filling needle; - Referring to
FIGS. 1-4 , afilling needle 10 of a fluid-dispensing system 11 is illustrated and includes aneedle portion 12 and ahub 14 affixed to theneedle portion 12. Theneedle portion 12 entirely comprises a metallic material such as stainless steel. Thehub 14 comprises a non-metallic material such as plastic or rubber. In an exemplary embodiment, thehub 12 comprises a medical grade polymer. - Referring to
FIGS. 1-3 in particular, theneedle portion 12 is an elongated cylindrical tube that defines afluid cavity 16, and includes a dispensingend 18 and receivingend 20. Thefluid cavity 16 of theneedle portion 12 terminates at a dispensing opening 22 of the dispensingend 18, and at a receiving opening 24 of the receivingend 20. Thereceiving end 20 is the end of theneedle portion 12 at which thehub 14 is affixed. - The
hub 14 also defines a cavity, referred to hereinafter as thehub cavity 26. Thehub cavity 26 is configured to contain the receivingend 20 of theneedle portion 12. The receivingend 20 of theneedle portion 12 is secured within thehub cavity 26 via any desirable means, such as adhesive, acrylic, injection molding, press fit or shrink fit. As is shown best inFIG. 1 , thehub 14 fixedly contains a portion of theneedle 12. Beginning from a terminal point of the receivingend 20, containment by thehub 14 extends a fraction of a length of theneedle 12 in a direction of the dispensingend 18. - As is best shown in
FIG. 1 , thehub 14 further includes an associatingportion 28. Referring toFIG. 4 , this associatingportion 28 is configured to securely associate thehub 14, andneedle portion 12 to which it is secured, to tubing 30 of thefluid dispensing system 11. Due to the properties of the plastic or rubber that comprise thehub 14, this tubing 30 (of which there are multiple individual tubes) is fixedly and securely associable with thehub 14 via africtional fit 32. When thehub 14 is securely associated withtubing 30, as shown inFIG. 4 , theneedle portion 12 is in fluid communication with thetubing 30 via the receiving opening 24 andfluid cavity 16. - With the
needle portion 12 in fluid communication with thetubing 30 via thefrictional fit 32 with thehub 14, fluid may be transported to theneedle portion 12 from a bulk supply of fluid held in areservoir 34 of thesystem 11. The fluid may be transported via a pump, which may be disposed with any or all of thereservoir 34,tubing 30, or fillingneedle 10. In some embodiments of thesystem 11, the pump is responsible for dispensing a desired amount of fluid into theneedle portion 12, which in turn dispenses the desired amount of fluid out of the dispensing opening 22, and into a desired container (such ascontainers 36 ofFIG. 4 ) or onto a desired surface. It should be appreciated that the pump may be any desirable means/device for actuating transportation of the desired quantity of fluid. The pump may be any type of known pump that is either automated or manual. The pump may also be a pressurized reservoir containing a bulk supply of fluid, wherein the pressurized reservoir includes a valve that opens and closes very accurately to measure and release the desired quantity of fluid. This type of “pump” is known as a time/pressure system. A time/gravity system may also be used, in which a reservoir is placed relatively above thefilling needles 10, and a valve is opened at desired intervals to take advantage of gravity. - As shown in
FIG. 4 , it should be appreciated that thesystem 11 may incorporatemultiple filling needles 10 that are moveable into dispensing position withcontainers 36 that are being transported along a conveying device. With this movement into dispensing position, via any type of manual or automated actuator, thesystem 11 may fill multiple groups of multiple containers as thecontainers 36 are transported along the conveying device. - After a batch (a desired number of containers 32) of
containers 32 is filled with a desired fluid, thefilling needles 10 may be disposed of due to theirnon-metallic hub 14, and the relative inexpensiveness of thefilling needle 10 including thishub 14 as compared an all metal filling needle (i.e. hub and needle being metal) and cleaning and sterilization. As theneedles 10 may be disposed of, cleaning and sterilization is unnecessary. In addition, thetubing 30 andhubs 14 may be permanently affixed via unitary construction, polymer welding, or gamma ray/electron processes. If unitary construction is employed, thetubing 30 andhubs 14 may comprise the same plastic or rubber material. Permanent affixing allows the time it takes to remove and replace fillingneedles 10 to also be efficiently (and cost effectively) limited. This is due to the ability of thenon-metallic hub 14 andtubing 30 to be quickly removed from thesystem 11, and anew filling needle 10 with permanently attachedtubing 30 to be quickly installed. - Referring to
FIGS. 5-8 , theneedle portions 12 andhub 14 of the fillingneedle 10 may include any configuration, size, shape, or fluid capacity that is known or conceivable in the art. - While the embodiments of the disclosed method and apparatus have been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the embodiments of the disclosed method and apparatus. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the embodiments of the disclosed method and apparatus without departing from the essential scope thereof. Therefore, it is intended that the embodiments of the disclosed method and apparatus not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out the embodiments of the disclosed method and apparatus, but that the embodiments of the disclosed method and apparatus will include all embodiments falling within the scope of the appended claims.
