many aspects of the invention can be better understood with the references made to the drawings below . the components in the drawings are not necessarily drawn to scale . instead , emphasis is placed upon clearly illustrating the components of the present invention . moreover , like reference numerals designate corresponding parts through the several views in the drawings . by way of a quick summary of the invention , the insert is color - coded to a particular broselow ® child size . each insert has a blocking ledge in a certain position such that it provides a stopping point beyond which a vial of medication cannot be pushed , thereby limiting the amount of medication that is delivered to a child . as the vial is depressed , medication flows through the needle and is stopped when the outer edge of the vial contacts the blocking ledge , thereby limiting the amount of medication delivered by the syringe . since the blocking ledges are located at different levels of the insert depending on the correct dosage for a child of that broselow ® color code , all emergency medical personnel have to do is select the proper color and medication from the kit provided . fig1 is a front view of the invention illustrating the basic physical structure of the insert . fig2 is a cross - sectional view , fig3 is a top view and fig4 is a perspective view of the insert shown in fig1 . the insert , generally referenced as 1 , is a cylindrical container with two sections : an insert top portion 2 which has a narrower outside diameter 5 than the second part , an insert bottom portion 4 , which has a larger diameter 6 . this is caused by the fact that the insert top wall thickness 7 has a thinner width than the width of the insert bottom wall thickness 8 . the increase in outside diameter between the insert top 2 and the insert bottom 4 causes a blocking ledge 3 . the insert 1 is placed in a syringe ( in a preferred embodiment , the syringe is a hospira abboject ®), with insert top 2 upright , and a vial of medication is installed by screwing the vial stopper into the syringe over the insert . the vial wall is then pushed down and medication flows through the syringe needle until the vial wall &# 39 ; s progress is stopped by the blocking ledge of the insert hitting a vial lip ( 17 as referenced in other figures ). thus , by adjusting the location of the blocking ledge 3 , the volume of medication delivered can be changed from insert to insert , such that the proper dosage is given to a child of that particular size . the outside diameter of the insert top 2 is small enough to allow a vial wall to slip over it , and the blocking ledge 3 is wide enough to prevent the vial wall from slipping any further down the insert , thereby limiting the amount of medication delivered from the vial through the syringe . fig5 is a cross - sectional view of the insert , syringe , and vial , which are the three basic components , that when used correctly , can provide an error - free dosage to a child . the syringe 9 is a cylindrical container with a needle 29 at one end and an open top . the insert 1 is slid into the open top and nestled at the bottom of the syringe . the vial 10 is a cylinder with a vial wall 13 with a vial wall width 11 , and open top defined by a vial lip 17 , a vial bottom 12 , where the inner sides of the vial wall define a vial internal diameter 22 . inside the cylinder is a quantity of medication 14 , and retaining the medication in the vial is a rubber plunger 15 . after insert 1 is placed within the syringe 9 , the vial is screwed onto the syringe . when properly installed the syringe needle 29 penetrates the rubber plunger 15 that is used to seal the vial of medication . note that as the vial is pushed down , the medication 14 will be directed through the needle 29 until the vial lip 17 hits the blocking ledge 3 . fig6 is a series of drawings showing cross - sectional depictions showing the insert positioning prior to and after installation into a syringe . fig7 is a series of drawings showing cross - sectional depictions showing how the insert appears when placed within the syringe and the vial is being attached . fig8 is a series of cross - sectional views showing the vial bring pressed into the syringe , delivering a dose limited by the step or “ blocking ledge ” in the insert . the insert 1 is slid into the syringe cavity 31 of the syringe 9 until the insert bottom 16 hits the syringe outer chamber bottom 27 . the syringe outer chamber width 26 is wide enough to accommodate the insert bottom wall thickness 8 , such that the insert 1 slides easily into the syringe 9 . the vial 10 is then attached to the syringe 9 . after the vial is installed on the syringe , the vial bottom 12 is pushed toward the blocking ledge 3 , the appropriate amount of medication 14 will flow through the needle 29 , until the vial lip 17 contacts the blocking ledge 3 . when the vial has been fully compressed to the point where the vial lip 17 has hit the blocking ledge 3 , the correct quantity of medication 14 has been properly delivered . the vial 10 is then pressed down . the vial internal diameter 22 is larger than the insert top outer diameter 5 , but less than the insert bottom outer diameter 6 , such that vial lip 17 , cannot be pushed beyond the blocking ledge 3 . thus , a set quantity of medication is injected through the needle 29 in the syringe inner chamber 28 , as the rubber plunger 15 in the vial mates to the syringe inner chamber stopper 30 , such as the medication 14 in the vial is injected up to the point where the vial lip 17 hits the blocking ledge 3 . because the blocking ledges are located at different heights in different colors of inserts , emergency medical personnel can easily pick the appropriate insert by matching it to the appropriate color code of the broselow ® pediatric emergency tape . fig9 is a cross - sectional view of the vial after it has been depressed as far as it will go , thereby limiting the dosage given to the child . the vial 10 has been pushed into the syringe 9 as far as it will go based upon the color of insert that was used . the blocking ledge 3 of the insert has stopped the vial wall 13 from entering the syringe 9 further , thereby limiting the amount of medication 14 , that was injected into the child . the threaded rubber plunger 15 has directed the medication 14 through the needle 29 . fig1 is a perspective view of a series of epinephrine inserts , each color coded to the appropriate “ zone ” of the broselow ® tape . note how the blocking ledge is a different distance “ down ” each insert , so that a particular color of insert will allow the proper dosage of a medication to a child whose height corresponds to the particular broselow ® color “ zone ”. fig1 is a front view of how the invention might appear in an emt &# 39 ; s medication kit , with different color - coded inserts for different medications , with each insert color coded to the appropriate “ zone ” of the broselow ® tape . the medication here , used by way of example , is epinephrine , a common emergency medication . the inserts are color coded to the appropriate broselow ® color zone , such that all an emt needs to do if dealing with a child under emergency circumstances is measure the child with the broselow ® tape and pick out the appropriate insert , then place the insert into the syringe , attach a vial of epinephrine , and depress the vial of epinephrine until the lip of the epinephrine vial hits the blocking ledge of the insert . fig1 is a front view of how the invention might appear in an emt &# 39 ; s medication kit , with different color - coded inserts 3 for different medications , with each insert color coded to the appropriate “ zone ” of the broselow ® tape and the type of medication written on each insert . note how the various color and size - coded inserts can be organized horizontally , or vertically , by either the medication type or the dosage category . it is also envisioned that other inserts or labels can be attached to the vial to provided various types of information , included but not limited to : name and concentration of the medication , amount based upon dosage weight , amount based on dosage volume , calculated amount based on pediatric patient weight , and color - coding based on broselow ® pediatric emergency tape . fig1 is a front view of how the invention might appear in another embodiment of an emt &# 39 ; s medication kit , with different color - coded inserts 3 for different medications , with each insert color coded to the appropriate “ zone ” of the broselow ® tape and the inserts organized by dosage category . it should be understood that while the preferred embodiments of the invention are described in some detail herein , the present disclosure is made by way of example only and that variations and changes thereto are possible without departing from the subject matter coming within the scope of the following claims , and a reasonable equivalency thereof , which claims i regard as my invention . all of the material in this patent document is subject to copyright protection under the copyright laws of the united states and other countries . the copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure , as it appears in official governmental records but , otherwise , all other copyright rights whatsoever are reserved .
this invention provides a means by which correct dosages of emergency medication can be provided to children under emergency situations . a color - and size - coded set of cylinders is provided where the colors match the color codes of the broselow ® pediatric emergency tape , a common method by which the proper dosage for child is estimated based on the child &# 39 ; s height . each type of medication in the emergency kit has its own color - coded set of cylinders , such that once emergency medical personnel measure the child and determine which medication to use , all they need to do is grab the correct cylinder based on the color . the invention allows emergency medical personnel to safely , efficiently , quickly , and accurately deliver the correct dosage of one or more medications to a child under emergency conditions .
