Definitions
- This invention relates to the delivery of relatively small amounts of materials, particularly, dental materials. More particularly, the invention relates to the use of a delivery tube for the delivery of such materials to precise locations.
- Some delivery systems which include a mechanical dispensing syringe. While these devices also work, they are rather expensive, and when compared to a simple brush, they are difficult and time consuming to operate. Further still, unless they are packaged in pre-filled, one-time use"(umt ⁇ o's'e'j hiarnier-tneyare' also subject to cross contamination between patients. Unit dose syringes, because of their relatively complicated design, also greatly increase costs involved with the procedure.
- a delivery system for a liquid includes a plastic or glass tube having a central passage longitudinally theretrough, preferably, axially.
- a resilient squeeze pump is positioned at some point along the longitudinal length of the tube, which can be employed to create suction at one end of the tube to thereby draw liquid into the tube.
- the tube is clear and is made from a flexible plastic material.
- a dental material delivery kit includes a reservoir or container of a liquid dental material to be delivered.
- the kit also includes a tube as above, which can be employed to transfer a desired quantity of the material to a target site and to dispense the material at that site. Further, the tube is configured to hold about as much material as required for a given dental procedure, thereby eliminating the need to remove the material from its reservoir or container more than once.
- FIG. 1 is a front elevational view of a delivery system according to the present invention, showing an inner, central passageway in phantom lines.
- FIG. 2 is a front elevational view of an alternative embodiment of a delivery system according to the present invention.
- FIG. 3 is a front elevational view of a still further alternative embodiment of a delivery system according to the present invention, showing a secondary orifice and part of a central passageway in phantom lines.
- FIG. 4 is a front elevational view of another alternative embodiment of a delivery system according to the present invention.
- Fig. 5 is an end view of the device of Fig. 1.
- a delivery system according to the present invention is shown by way of example by the number 10 on the attached drawings.
- Delivery system 10 may be used to transport and deliver any liquid or flowable material.
- delivery system 10 is particularly suited for removing an amount ' o ⁇ a d ' d a'r ' th ' at'e'rial 'sudh''a ⁇ an adhesive or sealant, from a reservoir or bottle (not shown) and to deliver a desired amount of the material to a target site, such as a tooth (not shown).
- delivery system 10 can be employed with any material, these include for example, PRIME & BOND ® adhesive and DELTON ® pit and fissure sealants available from DENTSPLY Intemational Inc. of York, PA.
- delivery system 10 includes a tube 11 having a central passageway 12 therethrough.
- central passageway 12 is longitudinally and axially positioned within tube 11, although this is not required.
- multiple passageways 12 are also within the scope of the invention.
- Passageway 12 also preferably extends from a dispensing end 20 to an opposite, venting end 21 (Fig. 1). Passageway 12 therefore, extends from an inlet orifice 22 proximate to dispensing end 20, to a venting orifice 23 (Fig. 5) proximate to venting end 21.
- venting it is meant that the orifice opens to the atmosphere.
- central passageway 12 opens to the atmosphere through venting orifice 23.
- Tube 11 may be fabricated from any material such as plastic or glass.
- tube 11 it is preferred to fabricate tube 11 from a clear, flexible plastic material, such as that used to fabricate the SaniTip ® air/water syringe tip, also available from DENTSPLY International Inc.
- Tube 11 may also be of any length or size, and may include a central passageway 12 of any dimension, depending upon the needs of the end use. Further, when tube 11 is fabricated from a flexible material, the shape of tube 11 may be changed by flexing, thereby allowing improved access to confined areas. [UUZ4J in use, tuoe 11 is graspe ⁇ m tne nan ⁇ ot"a ''user, , suc ' r ⁇ '" l ti ⁇ ai?
- tube 11 is inserted dispensing end 20 first, into a reservoir of the material to be dispensed (not shown) until a desired quantity of the material flows through dispensing orifice 22 and into central passageway 12. Material may flow into central passageway 12 by capillary action or the like. The determination of the amount of material is facilitated when tube 11 is clear, allowing the operator to visually inspect central passageway 12. Gradient marks 30 may be placed upon tube 11 to further facilitate the determination of the amount of material thereby taken up into central passageway 12.
- venting orifice 23 is closed off, preferably by the aforementioned use of the operator's finger, or by any other means.
- atmospheric pressure will cause the material to remain within central passageway 12, regardless of the orientation of tube 11.
- Tube 11 can then be moved to the target site and an amount of the material allowed to flow from central passageway 12 through dispensing orifice 22 by momentarily and/or partially uncovering venting end 23, causing pressure within central passageway 12 to again equal atmospheric. Material within central passageway may then flow under the influence of gravity or the like.
- a brush 31 may be provided proximate to dispensing end 20.
- Brush 31 can be used to direct and control the material flowing from dispensing orifice 22.
- a deformable, rubber-like or resilient squeeze pump 40 is provided at some point along the longitudinal length of tube 11, preferably between dTsp ' ehs ⁇ ftg d " 2 ⁇ ' ' anT venting ' end 21.
- an operator can squeeze or deform pump 40, thereby reducing its internal volume.
- suction is induced through central passageway 12, thereby inducing material to flow into central passageway 12 through dispensing orifice 22.
- pump 40 is again squeezed, thereby again reducing its internal volume, material in central passageway 12 is forced out of central passageway 12 through dispensing orifice 22, and is thereby dispensed.
- a dental material delivery kit includes a reservoir or container (not shown) of a liquid dental material to be delivered.
- the kit also includes a delivery system 10 as above, which can be employed to transfer a desired quantity of the material to a target site and to dispense the material at that site.
- delivery system 10 is configured to hold about as much material as required for a given dental procedure, thereby eliminating the need to remove the material from its reservoir or container more than once. That is, enough material can be drawn into central passageway 12 to facilitate several applications of the material to a target site, thereby eliminating the need to remove additional material from the original reservoir.
- a still further embodiment of the invention employs a squeeze bulb 60 (Fig. 4) to draw into and dispense material from tube 11.
