Description




FIELD OF THE INVENTION




The present invention generally relates to solution applicators and, more specifically, to solution applicators for applying antimicrobial solution to skin before surgery.




BACKGROUND AND SUMMARY OF THE INVENTION




Antiseptic preparation of patients for surgery typically includes applying antimicrobial solution to the patient's skin and scrubbing the affected area. There are a number of ways that these antimicrobial solutions are applied from the basic method of dipping a sponge or piece of cotton in an open dish of antimicrobial solution and applying the solution to the patient's skin to more complex, hand-held solution applicators.




There are a number of solution applicators that use spikes and other sharp members that puncture a cartridge or container that contains antimicrobial solution. In many of these types of solution applicators, the cartridge or container is moved longitudinally relative to the spike which then punctures the container to let the solution flow from the container to a sponge on the end of the applicator. These types of solution applicators can rupture during shipping, if the applicator is dropped or sufficient pressure is exerted onto one end of the applicators to thereby force the spike into the solution container, which can inadvertently or accidentally rupture the container and cause the solution to flow out of the container. Some examples of solution applicators using spikes are U.S. Pat. Nos. 4,415,288; 4,498,796; 5,120,301; and 5,769,552.




There are other solution applicators that involve the use of pressure to break or rupture an ampoule inside the applicator by squeezing the sides of the ampoule together. Other solution applicators require bending of an ampoule to break it or pushing an ampoule forward against a member which then bends the ampoule to break it, thereby releasing the solution so that it can then be applied. These types of solution applicators also have problems with breakage during shipping, when dropped, or inadvertently by a user that causes the compartment or ampoule inside of the solution applicator to rupture and thereby release the fluid solution when it is not desired. Some examples of these types of patents discussed above include U.S. Pat. Nos. 3,757,782; 5,288,159; 5,308,180; 5,435,660; 5,445,462; 5,658,084; and 5,927,884.




There is a need for a novel solution applicator that will not easily break during shipment, when dropped, or inadvertently by a user prior to desired use of the solution applicator. The present invention meets these needs. The present invention is a novel solution applicator comprising a solution container having a frangible twist-off member that enables solution in the solution container to flow out of the solution container when the twist-off member is twisted. The solution applicator also comprises an applicator head having a proximal end and a distal end and a solution pathway extending from the proximal end to the distal end, the applicator head being engaged with the solution container at the proximal end, the applicator head having an aperture and applicating material at the distal end, and the applicator end having a receiving member that the twist-off member engages when the applicator is rotated relative to the solution container to thereby open the solution container at the twist-off member to enable fluid to flow from the solution container through the solution pathway and through the aperture in the applicator head to the applicating material.




The solution applicator of the present invention is novel in that it includes a twist-off member that retains solution in the solution container until the solution container and the applicator head are rotated relative to each other to thereby cause the twist-off member to be twisted to create an opening in the solution container that allows solution to be applied. The present invention overcomes the difficulties of the prior art inventions in that it is highly unlikely that during shipment, when dropped or inadvertently by a user, the solution container would be rotated relative to the applicator head. This is a key feature of the present invention. Inadvertent openings of solution applicators usually occur if they are dropped or jammed or bent, so the twisting action required to open the solution applicator of the present invention is a very beneficial feature and superior to the prior art inventions.




Various objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the enclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as a basis for teaching one skilled in the art how to make and/or use the invention.




Referring now to the drawings, preferred embodiments of the solution applicator of the present invention are shown in

FIGS. 1-13

. The solution applicator


20


of the present invention includes a solution container


21


that contains the solution to be applied by the solution applicator


20


. The solution may be various types of liquids or gels to be applied on a surface, but the present invention is very useful for antimicrobial solutions applied to patients before surgery. The solution container


20


is self-contained in that no other implements, techniques or tools are necessary for accessing and applying the solution.




The solution container


21


may be shaped like a cylindrical bottle or shaped like other types of reservoirs or containers that hold solution. The solution container


21


includes a frangible, twist-off member


25


that enables solution in the solution container


21


to flow out of the solution container


21


when the twist-off member


25


is twisted to thereby provide an opening through which solution in the solution container


21


may flow. The twist-off member


25


may also be a type of twist-to-break member that will not actually twist off completely, but will break enough so that an opening will be created to allow the solution in the solution container


21


to flow out of the solution container


21


. This enables solution to be available for application by the solution applicator


20


.




The solution container


21


may include a cap


22


that is either integrally formed as part of the solution container


21


or the cap


22


may be designed for threaded connection to threads on the container portion


91


of the solution container


21


to thereby form a sealed solution container


21


to hold the solution. In this embodiment, the cap


22


would have the twist-off member


25


integrally formed as part of the cap


22


.




As shown in

FIGS. 1

,


2


,


2


A,


2


B,


2


C,


2


D and


3


, the solution applicator


20


includes an applicator head


26


engaged with the solution container


21


. The applicator head


26


has a proximal end


76


and a distal end


77


and a solution pathway


29


that extends from the proximal end


76


to the distal end


77


. Solution pathway


29


may be a tube, duct, channel, lumen, wick or other type of pathway through which liquids can flow. This solution pathway


29


allows solution to flow from the solution container


21


(when the twist-off member


25


is twisted to create an opening in the solution container


21


) and then to be able to flow through orifices/apertures


78


(see

FIG. 6

) to the applicating material


31


.




The applicating material


31


includes any type of material that will absorb the solution and allow the solution to be applied to a surface (e.g., a patient's skin). A suitable applicating material


31


for a solution applicator


21


is foam sponge, but many other suitable applicating materials


31


(such as cotton swabs, pads, etc.) that are porous and can retain and distribute solution may be used. It is preferable if the applicating material


31


allows the solution to flow into the applicating material


31


, but does not allow the liquid solution to drip from the porous applicating material


31


. Flat surface


30


provides a mounting surface to which the applicating material


31


is attached. The flat surface


30


has apertures


78


therethrough in order to allow the solution to get to the applicating material


31


from the solution pathway


29


.




Applicator head


26


may also have a slot


32


near the proximal end


76


that is engaged by a locating pin


23


that protrudes outwardly from the cap


22


of the solution container


21


to ensure proper orientation of the applicator head


26


as it is coupled to cap


22


of the solution container


21


. Locating pin


23


engages slot


32


to provide a means to retain the engagement of applicator head


26


onto cap


22


of the solution container


21


after assembly. Applicator head


26


has a receiving member


27


that forms an area that cooperates with twist-off member


25


such that when the applicator head


26


is rotated relative to the solution container


21


, the receiving member


27


will tear or break the twist-off member


25


, which opens the solution container


21


and enables solution to flow from the solution container


21


. The receiving member


27


can be formed in many suitable ways (including a tongue-and-groove arrangement), as long as it will engage and tear the twist-off member


25


when the applicator head


26


is rotated relative to the solution container


21


.




A preferred embodiment of the receiving member


27


is shown in

FIG. 3

, in which the receiving member


27


includes two parallel members


80


attached to a cross member


28


that extends across the solution pathway


29


of the applicator head


26


. As shown in

FIG. 3

, the parallel members


80


capture or mate with a portion of the twist-off member


25


and when the applicator head


26


is rotated relative to the solution container


21


, the twist-off member


25


is torn to provide an opening in the solution container


21


at the frangible portion


24


. Cross member


28


extends across the solution pathway


29


of the applicator head


26


and it can also be designed to be able to control the rate of fluid flow from the solution container


21


to the applicating material


31


. As shown in

FIG. 6

, there may also be apertures


78


that can also control the rate of flow of fluid and uniform distribution of solution to the applicating material


31


In a preferred embodiment, there are holes or apertures


34


through the receiving member


27


which are of sufficient size to allow enough solution to pass through the receiving member


27


to the applicating material


31


and also are of small enough size so that there is not too much solution going to the applicating material


31


.





FIGS. 4B and 5

show a portion of the solution container


21


with the twist-off member


25


, frangible area


24


and fluid path


37


(which is shown as the interior of the portion


36


that carries fluid from the container portion


91


of the solution container


21


to the frangible area


24


). For the embodiments in which the cap


22


is threaded to the container portion of the solution container


21


, protruding portion


38


forms a seal with the container portion


91


of solution container


21


to prevent leakage prior to the activation of the solution applicator


20


. Threads


39


engage with mating threads


82


of the container portion to lock the cap


22


and the container portion


91


together to form the solution container


21


.




Another preferred embodiment of a solution applicator


40


is shown in

FIGS. 7-13

. The solution applicator


40


includes a solution container


55


having a frangible twist-off member


52


and an applicator head


47


that engages with the solution container


55


such that the frangible twist-off member


52


is torn when the solution container


55


is rotated relative to the applicator head


47


. The solution is contained in the solution container


55


which can be formed in various shapes, including the oval-shaped solution container


55


shown in

FIGS. 7-9

and


12


. The solution container


55


is preferably locked in place to the applicator head


47


by having a lip


96


formed around the circumference of segment


42


of the applicator head


47


which mates with a holding ring


88


(see

FIG. 12

) that is like a channel around the circumference of the solution container's


55


circumference into which the lip


96


snaps to thereby put the applicator head and the solution container in locking engagement with each other. This lip


96


and channel


88


provide a sealed connection between the applicator head


47


and solution container


55


so that the solution does not escape between the applicator head


47


and solution container


55


. The engagement between the lip


96


and channel


88


allow rotation of the applicator head


47


relative to the solution container


55


, so that the twist-off member


52


can be torn to create an opening to allow solution to flow from the solution container


55


to the applicating material


65


on the end of the applicator head


47


.




The applicator head


47


has a receiving member


53


(as shown in

FIGS. 10

,


10


A and


10


B) that receives the twist-off member


52


such that twisting of the applicator head


47


(and therefore receiving member


53


) relative to the solution container


55


(and therefore twist-off member


52


) will cause the twist-off member


52


to tear an opening in the solution container


55


to thereby allow solution to flow from the solution container


55


into the applicator head


47


. The receiving member


53


also may have apertures


59


therethrough that help control the flow of fluid past and through the receiving member


53


so that the solution can flow to the applicating material


65


. The solution applicator


40


may also contain indicia


13


,


97


which indicate to the user that the user needs to rotate the applicator head


47


relative to the solution container


55


such that the indicia


13


,


97


are aligned, which is a signal to the user that the twist-off member


52


has been twisted enough to break it so that there is an opening in the solution container


55


to release the solution into the applicator head


47


. Indicia


13


,


97


may be holes, markings, words, protrusions and various other suitable types of indicia that will enable a user to know when the rotation has been sufficient to tear or break the twist-off member


52


. Solution container


55


may also be squeezable so that a user can squeeze the solution container


55


to increase the flow of solution to the applicator head


47


.




The parts of the solution applicator


40


may be made of numerous types of plastic materials including high density polyethylene, polypropylene, low density polyethylene or polyvinyl chloride (PVC). The solution container


55


preferably has a grip portion


41


that a user can easily grasp the solution container


55


to rotate it relative to the applicator head


47


.




In another preferred embodiment, the twist-off member


52


may also have a retainer mechanism


92


as shown in

FIG. 12A

that allows the twist-off member


52


to slide into the receiving member.


53


and then the retainer mechanism


92


expands such that the twist-off member


52


cannot be pulled back from the receiving member


53


. This helps hold the solution container


55


together with the applicator head


47


. In a preferred embodiment, said retainer mechanism


92


is V-shaped with a spring force such that the legs of the V squeeze together when the retainer mechanism


92


and the twist-off member


52


start to be inserted into said receiving member


53


. The legs of the V spring apart when said retainer mechanism


92


is fully inserted into said receiving member


53


to thereby hold said applicator head


47


and said solution container


55


together. The retainer mechanism


92


is preferably part of the twist-off member


52


. The retainer mechanism


92


can be molded as ribs coming off the end of the break off section of the twist-off member


52


, so that after pushing the end part of the solution container that contains the twist-off member


52


into the applicator head


47


, the ribs of the retainer mechanism


92


lock in place into the receiving member


53


making it impossible for the applicator head to be removed from the solution container prior to activation (twisting and breaking the twist-off member


52


). It is preferable that the retainer mechanism


92


be formed of the same material as that of the twist-off member


52


.




The applicator head


47


preferably has a solution pathway


50


that enables solution to flow from the opening from the torn twist-off member


52


past the receiving member


53


on through the applicator head


47


to the applicating material


65


, which is attached to flat end


48


of the applicator head


47


. The flat end


48


and the applicating material


65


are preferably formed at an angle as shown in

FIGS. 9 and 10

to make them ergonomically designed for the user. The flat end


48


with an orifice


49


therethrough is shown in FIG.


11


. The orifice


49


may be of various sizes and could have a number of smaller holes therethrough to obtain a suitable flow rate of the solution to the applicating material


65


. The applicating material


65


is attached to the flat end


48


and the flat end


48


may have radial slots


89


to allow solution to flow evenly to the applicating material


65


.




The twist-off member


52


is preferably a tab that extends outwardly from the solution container


55


and that is connected to the rest of the solution container


55


by a frangible web


99


that will tear when the tab is twisted off or twisted to break. This frangible web


99


is designed so that when the twist-off member


52


is twisted or rotated, the frangible web


99


will tear open to provide an opening for the solution to flow out of the solution container


55


. It is preferable to have the frangible web


99


be somewhat thinner than the walls of the rest of the solution container


55


so that it tears more easily at the location of the frangible web


99


. Ring


90


helps retain solution in the applicator head


47


so that it does not get on the user's hands near channel


88


.
