Referring now to the drawings, the present invention is a weight based pediatric syringe system and is generally referred to with numeral 10. It can be observed that it basically includes plunger 12 and barrel 14.

As seen in figure 1 , present invention 10 is a pump consisting of plunger 12 that fits tightly in barrel 14. Plunger 12 comprises an end fitting, piston and plunger seal. Plunger 12 can be pulled and pushed along inside barrel 14, allowing present invention 10 to take in and expel a liquid or gas through an orifice at the open end of barrel 14. Barrel 14 typically comprises a flange as illustrated. The open end of barrel 14 may be fitted with luer lock assembly 17, a nozzle, or tubing to help direct the flow into and out of barrel 14. In a preferred embodiment, present invention 10 is used to administer injections, insert intravenous drugs and/or medications into the bloodstream of a patient. In a preferred embodiment, barrel 14 comprises units of volume scale 20 and units of mass scale 22.

As seen in figure 2, in an alternate embodiment, barrel 14 comprises units of volume/ mass scale 21.

As seen in figure 3, the open end of barrel 14 may instead be fitted with tip 16 having hypodermic needle 18 to help direct the flow into and out of barrel 14 when administering injections, and inserting intravenous drugs and/ or medications into the bloodstream of the patient. Tip 16 may be, or comprise, a needle attachment, and / or adaptor. Present invention 10 is designed to accurately graduate a volume of drugs and/or medications with a specific concentration to be administered, whereby the units of volume in units of volume scale 20 are directly proportionate to the units of mass in units of mass scale 22, based on a mass of the patient. In addition, units of volume scale 20, units of mass scale 22, and units of volume/ mass scale 21 allow for easy visibility of kilogram marks allowing a healthcare provider to dose a 1 kg patient as accurately as a 40 kg patient as an example. Furthermore, a unique relationship of present invention 10 to a specific drug and/or medication will result in varying barrel 14 diameters and length to create an easy to view graduation.

In a preferred embodiment, units of volume may be cubic centimeters, which is the same volume as the milliliter (mL or ml) . A cubic centimeter (International System of Units (SI) unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that extends the derived Si-unit cubic meter, and corresponds to the volume of a cube that measures 1 cm ^χ 1 cm x 1 cm. One cubic centimeter corresponds to a volume of 1 / 1 ,000,000 of a cubic meter, or 1 / 1 ,000 of a liter, or one milliliter; thus, 1 cm³ = 1 ml. Many scientific fields have replaced cubic centimeters with milliliters. The medical fields in the United States still use the term cubic centimeter.

In a preferred embodiment, units of mass may be kilogram or kilogramme (SI unit symbol: kg; SI dimension symbol: M), which is the base unit of mass in the SI Metric system and is defined as being equal to the mass of the International Prototype of the Kilogram (IPK). The avoirdupois, or international, pound, used in both the Imperial system and U.S. customary units, is defined as exactly 0.45359237 kg, making one kilogram approximately equal to 2.2046 avoirdupois pounds. Other traditional units of weight and mass around the world are also defined in terms of the kilogram, making the IPK the primary standard for virtually all units of mass on Earth.

In a preferred embodiment, barrel 14 is color-coded to match a drug and/or medication label color code for easy identification. As an example, barrel 14 can be tan in color to match a specific drug and/or medication tan label color code such as epinephrine 1 : 10,000. Optionally, plunger 12 can also be tan in color to match its respective barrel 14 and the drug and/or medication tan label color code.

As another example, barrel 14 can be pink in color to match a specific drug and/or medication pink label color code such as epinephrine 1 : 1 ,000. Optionally, plunger 12 can also be pink in color to match its respective barrel 14 and the drug and/or medication pink label color code. As another example, barrel 14 can be maroon in color to match a specific drug and/or medication maroon label color code such as amiodarone 50 mg/cc concentration. Optionally, plunger 12 can also be maroon in color to match its respective barrel 14 and the drug and/or medication maroon label color code.

Therefore, present invention 10 is medication specific meaning that each weight based pediatric syringe system is specific to a particular drug and/ or medication concentration. As an example, drugs and/ or medications administered with present invention 10, can be, but are not limited to treat: cardiac arrest, seizure, sedation, and/ or cardiac arrhythmia. In another embodiment, barrel 14 is marked with a specific drug and/ or medication for administration of that specific drug and/ or medication. Meaning that relevant drug and/or medication information, including concentration, is placed onto barrel 14 itself. The relevant drug and/or medication information can be placed on a sticker, engraved, or otherwise placed thereon, as an example. Optionally, plunger 12 is also marked with the specific drug and/ or medication for administration of said specific drug and / or medication. Seen in figure 4 is an example of weight based pediatric syringe system 10 in use, the units of volume to units of mass for epinephrine 1 : 10,000 is 0.1 cc/kg or equivalent units of volume and units of mass thereof. Seen in figure 5 is another example of weight based pediatric syringe system 10 in use, the units of volume to units of mass for amiodarone 50 mg/cc concentration is 0. 1 cc (5 mg/kg) or equivalent units of volume and said units of mass thereof. These two drugs are the primary drugs for cardiac arrest set by American Heart Association.

Another example of weight based pediatric syringe system 10 in use, Adenosine, which comes in 3 mg/cc concentration and has a initial dosing of 0.1 mg/kg up to max of 6 mg, which is the adult dose. Subsequent Adenosine dosing is 0.2 mg/kg up to the maximum adult dose, which is 12 mg. Another example of weight based pediatric syringe system 10 in use, Atropine, which comes in 1 mg/ 10 cc is dosed at 0.02 mg/kg with minimum dose starting at 0.1 mg up to a max dose of 0.5 mg. Another example of weight based pediatric syringe system 10 in use, Calcium Chloride 10%, which comes in a concentration of 1 GM/ 10 cc or 100 mg/cc is dosed at 20 mg/kg.

Another example of weight based pediatric syringe system 10 in use, Sodium Bicarbonate 8.4%, which comes in a concentration of 1 mEq/cc is dosed at 1 mEq/kg. Another example of weight based pediatric syringe system 10 in use, Sodium Bicarbonate 4.2%, which comes in a concentration of 0.5 mEq/cc is dosed at 1 mEq/kg. Another example of weight based pediatric syringe system 10 in use, Midazolm, which comes in a concentration of 1 mg/cc is dosed at 0. 1 mg/kg with max dosing not exceeding 2 mg to 2.5 mg depending on regional medical direction. Another example of weight based pediatric syringe system 10 in use, Diazepam, which comes in a 5 mg/cc concentration is dosed at 0.2 mg/kg and max dosing is at the adult dose of 5 mg.

Present invention 10 may be utilized on any human. However, in a preferred embodiment, the patient is under 50 kg. Present invention 10 comprising units of volume scale 20, units of mass scale 22, or units of volume/ mass scale 21 providing weight based administration of given drugs and/or medications, at system wide standard concentrations, is ground breaking in pediatric medicine. Present invention 10 allows a provider everything they need to deliver the drugs and/ or medications accurately in emergency care settings including cardiac arrest. Differentiation between adult and weight based pediatric dosing is considered nationally by either meeting minimum weight set by American Heart Association or minimum age. Also this differs under different medical direction in which doctors may create their own cut off for that region or system. The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
