FIELD OF THE INVENTION

One or more embodiments of the invention generally relate to pharmaceuticals. More particularly, the invention relates to weight based premeasured single doses of pediatric medication.

BACKGROUND OF THE INVENTION

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. Medication errors and dosing errors in particular are believed to be a large problem in medical settings. Due to the point that the size of pediatric patients can vary greatly depending on the age of the patient, one may expect that these errors may be especially problematic in the pediatric population. For example, without limitation, a 1 week old may be half the size of a 6 month old and a fraction the size of a 5 year old. Therefore, a medication dose for a 5 year old may likely be lethal for a 1 week old. Furthermore, it is contemplated that the rate of medication errors may be made worse depending on the situation in which the medications are being given. For example, without limitation, error rates in pre-hospital patients treated by EMS services or in emergency and resuscitation situations in hospitals may likely be greater than error rates for patients in non-emergency, hospital situations. Moreover, it is contemplated that the risk of negative outcomes as a result of medication errors may increase during an emergency as many of the drugs administered during an emergency are high-alert medications and patients are often in a vulnerable state.
Medication dosage errors in pediatric patients are largely attributable to the need to calculate weight based dosages. If an adult is being resuscitated, most of the first line drugs given emergently are typically in prefilled syringes containing a single dose. For example, without limitation, if a physician requests epinephrine, a nurse is usually able to take an epinephrine syringe from an emergency drawer and inject the entire contents through the patient's IV. This single dose is normally the correct dose for almost all adults. In contrast, most medications for pediatric patients are typically provided in containers or vials that have a large concentrated dose of medication from which the recommended dose is drawn. In an emergency situation, a pediatric patient's weight is estimated using a conventional method such as, but not limited to, basing the weight on the age of the patient or utilizing a measuring tape that uses length, body surface area, limb measurements or a combination to estimate the patient's size. Then, a pediatric medication chart is typically used to determine the appropriate dose of the specific medication for a child of that size. In some cases, the medication dose may need to be converted from the concentration of the vial containing a larger dose of the medicine, drawn up, and finally given to the patient. Additionally, the various different medications that may be requested by the physician, of which there are many, may each have a unique concentration, dose, volume, etc. Often these calculations can be complex. Due to the potential complexity of this process, one may expect that treatment may be delayed or that mistakes may be made. In addition, calculating dosages may cause additional stress for personnel or the patient during an emergency situation. Currently, it is believed that there is no way to avoid performing calculations to administer the correct dose of most pediatric medications, even in a relaxed non-urgent situation. For example, to administer ibuprofen to a pediatric patient, the doctor first determines how many milligrams (mg) per kilogram to give to the patient, and the medication is ordered as a mg dose. The ibuprofen is typically provided in a concentrated dose of say 100 milligrams in 5 milliliters. Therefore, the medical staff must then calculate the volume of the liquid to administer to the patient.
The following are examples of specific aspects in the prior art that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. By way of educational background, an aspect of the prior art generally useful to be aware of is that current solutions to administering the appropriate dose of many medications to a pediatric patient, particularly in an emergency or resuscitation situation, typically require the medical personnel to perform calculations or to prepare the medication to some degree. For example, one current solution involves a concept to reconstitute all pediatric resuscitation medications into a standardized formulation/concentration so that the dose of all of these medications is the same volume for a given weight range. Using this method the medical personnel estimates the weight of the patient and then calculates the volume of medication that would be an appropriate dose for any of the medications made in this standardized concentration. Another current solution involves using a measuring tape to estimate the weight of the patient based on their length. Then a color associated with a child of that size is assigned to the patient. Once a color for a patient has been determined, this color may be used to formulate all of the dosage calculations for that patient. For example, if a patient is indicated by the measurements to fall into the blue category, a list of the appropriate dosages of multiple medications may be found on the blue page in a medication folder. However, the medication dose typically must still be calculated and drawn up. Furthermore, problems may arise if a member of the medical team is color blind. There may also be problems of continuity if, for example, the ambulance company uses this system and the receiving hospital does not or vice versa.
In view of the foregoing, it is clear that these traditional techniques are not perfect and leave room for more optimal approaches.

As is well known to those skilled in the art many careful considerations and compromises typically must be made when designing for the optimal manufacture of a commercial implementation any system, and in particular, the embodiments of the present invention. A commercial implementation in accordance with the spirit and teachings of the present invention may configured according to the needs of the particular application, whereby any aspect(s), feature(s), function(s), result(s), component(s), approach(es), or step(s) of the teachings related to any described embodiment of the present invention may be suitably omitted, included, adapted, mixed and matched, or improved and/or optimized by those skilled in the art, using their average skills and known techniques, to achieve the desired implementation that addresses the needs of the particular application.
It is to be understood that any exact measurements/dimensions or particular construction materials indicated herein are solely provided as examples of suitable configurations and are not intended to be limiting in any way. Depending on the needs of the particular application, those skilled in the art will readily recognize, in light of the following teachings, a multiplicity of suitable alternative implementation details.
One embodiment of the present invention may provide weight based, prepackaged pediatric medications comprising a single dose of medication that may be uniquely appropriate for a specific patient weight or weight range. This embodiment may enable medical personnel to administer an appropriate dose of medication without the need to measure, scale, calculate, or draw up the dose as these medications may be available from the manufacturer in pre-measured doses with corresponding patient weights indicated on the containers. In some embodiments, the entire contents of the medication container may be the appropriate dose for a patient whose weight corresponds to the weight indicated on the container. By typically eliminating the need to calculate, measure, or draw up pediatric medications, it is believed that some embodiments of the present invention may help in reducing or practically eliminating medication dosing errors. Furthermore, some embodiments may ensure that medication is administered in a timely manner and may help to reduce stress on medical staff.
FIG. 1 is a diagrammatic side view of an exemplary syringe 100 comprising a premeasured dose of medication for a pediatric patient, in accordance with an embodiment of the present invention. In the present embodiment, syringe 100 comprises an appropriate dose of Epinephrine for a child weighing between 12-14 kg as indicated by a drug label 105 and a patient weight classification 110. Some existing weight ranges for dosing pediatric patients in emergency situations are 3-5 kg, 6-7 kg, 8-9 kg, 10-11 kg, 12-14 kg, 15-18 kg, 19-23 kg, 24-29 kg, 30-36 kg. These weight ranges may be used generally or narrowed further to give more accurate dosing, particularly in the lower ranges. For example, the 3-5 kg range may be further reduced to 3 kg, 4 kg, 5 kg or smaller. It is anticipated the specific weight ranges used for the implementation of this invention may be decided by a panel of Pediatric Medical and Pharmaceutical experts. Some embodiments may be implemented to incorporate more or fewer weight groups. In the present embodiment, there may be a different single dose syringe or another type of container to coincide with each of these weight ranges. For example, without limitation, if a patient falls into the 12-14 kg weight range, the medical personnel may have access to a variety of medications in syringes or other types of containers in premeasured doses for a child of that weight. For practically every medication that may be given to a pediatric patient, there may be dispensing devices such as, but not limited to, syringes, medication cups, tablets, suppositories, drops, nebulizers or IV bags that comprise premeasured doses of a these medications, each of which is appropriate for a specific weight group. Medications that may be provided in these premeasured, single dose containers may include, without limitation, all common medications that may be administered in emergency or resuscitation situations and in non-emergency situations, as well as chemotherapy drugs, dialysis treatments, IV contrasts and dyes for radiology, etc. Some of these medications may include, but are not limited to, epinephrine, atropine, lidocaine hydrochloride, etomidate, midazolam, ketamine, fentanyl citrate, morphine sulfate, thiopental sodium, succinylcholine chloride, pancuronium bromide, vecuronium bromide, lorazepam, diazepam, naloxone, adenosine, calcium gluconate, dextrose, sodium bicarbonate, phenobarbital sodium, ibuprofen, acetaminophen, etc. In some embodiments, blood and blood products may also be prepackaged in such a way that the volume of the blood matches the correct volume required for the weight range of the child. Some embodiments may be configured to administer medications to adults when doses may vary depending on various different factors such as, but not limited to weight, age, sex, condition, etc. Other embodiments may be implemented for use in a multiplicity of suitable applications including, without limitation, veterinary applications, etc.
In the present embodiment, syringe 100 may be clearly marked with the name of the medication with drug label 105 and the patient weight range for which the dose is appropriate by weight classification 110. Similar markings may be placed on the container regardless of the type of container. For example, without limitation, the name and weight range may be clearly marked on single dose medication cups, IV bags, etc. In some embodiments the medication container may comprise a variety of additional or different information such as, but not limited to, the actual dosage of the medication, any legally mandated indicia, warnings, possible side effects, etc. In some embodiments the weight range may be shown in multiple or different units of weight including, without limitation, kilograms, pounds, ounces, etc. It is contemplated that in some embodiments, weight classification 110 may comprise various different types of indicators 120 in addition to or rather than the written form of the weight range to indicate which weight range may be given that specific dose. For example, without limitation, each weight group may be identified by, but not limited to, an icon, a symbol, an image of a unique animal and/or a cartoon character, etc. In this case perhaps an image of an animal may be used to represent a 6 kg weight group so that each syringe or container with the appropriate dose for a child weighing 6 kg comprises an image of an animal, regardless of the medication, volume of medication, method of administration of the medication, etc. As part of a system that may incorporate premeasured doses of pediatric medications, the patient may also be provided with a wrist band 600, sticker or stamp etc comprising an image of the corresponding animal, which may be checked against the indicator 120 on the medication being dispensed to generally ensure the correct dose is administered. Alternatively, as illustrated by way of example in FIG. 2, the container may be colored to correspond to a color code representing various weight ranges. Similarly, the patient may wear a wrist band 600 (See FIG. 6) of the same color to check against the medication containers. Those skilled in the art will readily recognize, in light of and in accordance with the teachings of the present invention, that a multiplicity of suitable indicators 120 may be used to associate the container to a specific weight range such as, but not limited to, cartoon characters, animals, shapes, letters, numbers, names, symbols, etc. In addition, scales incorporating the specific weight ranges and associated indicator into their measurements may also be implemented to further ensure that the correct weight range is determined for the patient. For example, without limitation, when a patient is weighed on such a scale, the weight of the patient may be displayed as well as the indicia used to differentiate that weight range, e.g., a color or an image of an animal, etc.
FIG. 2 is a diagrammatic side view of an exemplary color coded syringe or vial 200 comprising a premeasured dose of medication for a pediatric medication, in accordance with an embodiment of the present invention. In the present embodiment, syringe 200 comprises an appropriate dose of Epinephrine for a child weighing between 12-14 kg as indicated by a drug label 205 and a patient weight classification 210. The body of syringe 200 is yellow to correspond to the weight range of 12-14 kg for which the dose of medication in syringe 200 is appropriate. It is contemplated that some embodiments using color coding may use different colors to represent different weight ranges. For example, without limitation, some embodiments may be configured to correspond to the color coding schemes of existing resuscitation systems such as, but not limited to, the Broselow system, the Antevy system, and any future systems that may be developed. Other embodiments may use a unique color coding system. In some embodiments the syringe or other medication container may comprise a dot or stripe of the color rather than being fully colored. In some embodiments, weight classification 210 may also incorporate the use of a weight range indicator 220 such as, but not limited to, an animal image in addition to the color coding. In additional embodiments, the patient may wear a wrist band 600 (See FIG. 6) of the same color coding and/or the animal image to check against the color coded syringe 200 being dispensed to generally ensure the correct dose is administered without having to do any calculations.
FIG. 3 is a diagrammatic front view of an exemplary IV bag 300 containing normal saline comprising a premeasured dose of medication for a child or pediatric patient, in accordance with an embodiment of the present invention. Medication dosage errors in pediatric patients are largely attributable to the need to calculate weight based dosages. Often these calculations can be complex. Due to the potential complexity of this process, one may expect that treatment may be delayed or that mistakes may be made resulting in medication dosage errors. In the present embodiment, IV bag 300 comprises an appropriate dose of normal saline for a child within a certain weight (range), an example of which is shown for a child weighing between 7-7.9 kg as indicated by a drug label 305 and a patient weight classification 310. In certain embodiments, IV bag 300 may be color coded to the predetermined weight classification 310. In some embodiments, weight classification 310 may also incorporate the use of a weight range indicator 320 such as, but not limited to, an animal image in addition to the color coding. In additional embodiments, the patient may wear a wrist band 600 (See FIG. 6) of the same color coding and/or animal image to check against the IV bag 300 being dispensed to generally ensure the correct dose is administered without having to do complex calculations. In other embodiments, any IV infusion medications such as, but not limited to, IV fluids and/or IV medications such as antibiotics should be the correct total volume for a child of the stated weight range. In practice, where IV infusions such as, but not limited to, an antibiotic that may need to be reconstituted into an IV bag 300, both the premeasured volume of the antibiotic, which may be retained in the vial or syringe 200 and the premeasured volume of the normal saline, which may be retained in the IV bag 300, is specific to the weight group of the child. So a nurse or caregiver may add the entire content of antibiotic in the vial or syringe 200 with the IV fluid in the IV bag 300, without the necessary calculations, which may introduce dosage errors. By administering the premeasured dose of the IV fluid and the premeasured volume of the IV medication in the IV bag 300, the child is getting the correct dose, and without dosage errors.
FIG. 4 is a diagrammatic front view of an exemplary suppository 400 comprising a premeasured dose of Acetaminophen for a pediatric patient in a certain weight class, in accordance with an embodiment of the present invention. Medication dosage errors in pediatric patients are largely attributable to the need to calculate weight based dosages. Often these calculations can be complex. Due to the potential complexity of this process, one may expect that treatment may be delayed or that mistakes may be made resulting in medication dosage errors. In the present embodiment, suppository 400 comprises an appropriate dose of Acetaminophen for a child within a certain weight (range), an example of which is shown for a child weighing between 5-5.9 kg as indicated by a drug label 405 and a patient weight classification 410. In other embodiments, suppository 400 may be color coded to the predetermined weight classification 410. In some embodiments, weight classification 410 may also incorporate the use of a weight range indicator 420 such as, but not limited to, an animal image in addition to the color coding. In additional embodiments, the patient may wear a wrist band 600 (See FIG. 6) of the same color coding and/or animal image to check against the suppository 400 being dispensed to generally ensure the correct dose is administered without having to do complex calculations, which may introduce dosage errors.
FIG. 5 is a diagrammatic back view of an exemplary blister pack 500 comprising a premeasured dose of Ibuprofen for a pediatric patient, in accordance with an embodiment of the present invention. Medication dosage errors in pediatric patients are largely attributable to the need to calculate weight based dosages. Often these calculations can be complex. Due to the potential complexity of this process, one may expect that treatment may be delayed or that mistakes may be made resulting in medication dosage errors. In the present embodiment, blister pack 500 comprises an appropriate dose of Ibuprofen for a child within a certain weight (range), an example of which is shown for a child weighing between 18-20 kg as indicated by a drug label 505 and a patient weight classification 510. In other embodiments, blister pack 500 may be color coded to the predetermined weight classification 510. In some embodiments, weight classification 510 may also incorporate the use of a weight range indicator 520 such as, but not limited to, an animal image in addition to the color coding. In additional embodiments, the patient may wear a wrist band 600 (See FIG. 6) of the same color coding and/or animal image to check against the blister pack 500 being dispensed to generally ensure the correct dose is administered without having to do complex calculations, which may introduce dosage errors.
FIG. 6 is a diagrammatic front view of an exemplary wrist band 600, in accordance with an embodiment of the present invention. In the present embodiment, wrist band 600 may be clearly marked with the patient personal identifiable information including name of the patient, date of birth of the patient, and a unique MRN. medication with drug label 105 and the patient weight range for which the dose is appropriate by weight classification 110. As part of a system that may incorporate premeasured doses of pediatric medications, the patient may also be provided with a wrist band 600 comprising patient actual weight and weight classification 610, and an image of a unique animal or cartoon character 620, which may be checked against the indicator 120, 220, 320, 420 and 520 on the medication being dispensed to generally ensure the correct dose is administered. Those skilled in the art will readily recognize, in light of and in accordance with the teachings of the present invention, that a multiplicity of suitable indicators 620 may be used to associate the containers 100, 200, 300, 400, and 500 to a specific weight range such as, but not limited to, icons, cartoon characters, animals, shapes, letters, numbers, names, symbols, etc. In addition, scales incorporating the specific weight ranges and associated indicator into their measurements may also be implemented to further ensure that the correct weight range is determined for the patient. For example, without limitation, when a patient is weighed on such a scale, the weight of the patient may be displayed as well as the indicia used to differentiate that weight range, e.g., a color, a cartoon character, a symbol, an icon, a name or an image of an animal, etc.
In typical use of an embodiment of the present invention, the patient's weight is first obtained on a scale or estimated using a measuring tape or some other weight estimating device. Virtually any medication that may be administered to the patient and some other types of treatments such as, but not limited to, fluids, imaging dyes or contrasts, or nutritional supplements may be available to the medical personnel in premeasured, single dose containers corresponding to specific patient weight ranges. Medication dosage errors in pediatric patients are largely attributable to the need to calculate weight based dosages. Often these calculations can be complex. Due to the potential complexity of this process, one may expect that treatment may be delayed or that mistakes may be made. The medications in these containers may be given immediately to the patient typically without the need to perform dosing calculations or the need to draw up the medication from a larger vial or container. A doctor may order a pediatric medication as a standardized order based on the weight range of the patient. The order would typically correspond to the weight range indicated on a pre-measured, single dose syringe or another type of container. The nurse or other medical personnel may then be able to administer the medication quickly and easily by simply obtaining the medication in a premeasured, single dose container, ensuring that the weight range on the container is appropriate for the patient, and administering the entire dose to the patient. By administering the entire contents of the medication container, the nurse typically gives the patient the optimal dose of that medication for a child of that weight.
It is contemplated that, whenever possible, the single dose containers in which the medications are provided may be the dispensing device or final packaging for the medication. For example, without limitation, IV push meds may be provided in a syringe that may be administered directly into an IV without measuring or drawing up the medication. Oral medications may be provided in a syringe that can be squeezed into the patient's mouth or in a medication cup that can be sipped. IV fluids may be provided in a bag with the appropriate volume for the weight range. Where medications require reconstitution with a dissolving solution, for example, without limitation, antibiotics, both the medication in the vial holding the medication and the volume of the bag of dissolving solution may be provided in the appropriate dose to administer to the patient in full based on their weight range, with no waste or calculations required. Those skilled in the art will readily recognize, in light of and in accordance with the teachings of the present invention, that medications and treatments administered through various different means may incorporate single dose dispensing containers according to some embodiments of the present invention. Some non-limiting examples of these types of medications and treatments include but are not limited to, inhaled, iv bolus, iv fluids, iv infusion, intramuscular, oral, nebulized, sub cutaneous, sub lingual, topical, dermal, intradermal, transdermal, intraosseous, intra-articular, intranasal, urethral, vaginal, aural, ocular, nasal, suppositories, treatments administered through nasogastric tubes, gastric tubes, and feeding tubes etc. In some embodiments medications may be provided in premeasured single dose containers that are not dispensing devices, such as but not limited to, vials. In these embodiments, the appropriate dose of the medication for that patent may be premeasured, yet the medication may still need to be drawn up into a dispensing container such as, but not limited to, a syringe or otherwise prepared to be administered.
The use of premeasured single dose medication containers according to some embodiments of the present invention may help to prevent problems associated with medication dispensing errors during pediatric medication dispensing generally and pediatric resuscitation especially. The single dose containers may also help to ensure that the patient typically receives the medication in a timely fashion as no calculations need to be made or medications drawn up from a vial. The ease of administration of medications in single dose containers may also reduce stress on the medical staff, especially during emergencies. Furthermore, medication ordering may be easier for doctors, and medication administration may be easier for nurses and other medical personnel. In addition, research into medications and methods may be unreliable due to improper dosing when using current dosing methods. This issue may be reduced or eliminated with the use of some embodiments since researchers may be more confident in the data they were receiving because of more accurate dosing.
For safety reasons, some embodiments may incorporate a system to hold these pre-dosed medications, with each weight group having their own unique drawer or container. For example, without limitation, a mobile cart with multiple drawers may be used with a unique drawer or container for each weight range that holds only syringes and other drug containers with appropriate dosing for that weight range, similar to a pediatric resuscitation cart. In some embodiments each drawer or container may be color coded to correspond to existing resuscitation color codes such as the Broselow system or the Antevy system, or other weight range color coding systems. Within each drawer or container there may be at least one single dose container for multiple medications. The single dose containers may be clearly marked with the name of the drug and the weight range. The single dose containers may also comprise other information such as, but not limited to, actual dosage, color coding, side effects etc. For further safety, each medication may have a separate compartment within each drawer, which is clearly labelled with the name of the medication. In emergency situations it is specifically anticipated that this system may be used in conjunction with existing or future pediatric resuscitation or emergency systems including but not limited to the Broselow system, the Broselow Luten system, the Broselow Hinkle system, the Pediatric cart, the Broselow pediatric cart, the Artemis system, the Antevy system, the Mercy tape, etc. Some embodiments may use a multiplicity of suitable systems for holding and organizing pre-dosed medication such as, but not limited to, a cupboard or cabinet, an automated medication dispenser, a shelving system, refrigerated storage, a moveable trolley, a carry bag etc.
Those skilled in the art will readily recognize, in light of and in accordance with the teachings of the present invention, that some embodiments of the present invention may be used in almost any medical environment including, without limitation, doctors' offices, ambulances, hospitals, clinics, etc. Moreover, some embodiments may be configured for over the counter medications such as, but not limited to, ibuprofen, acetaminophen, antihistamines, etc. It is contemplated that medications provided in premeasured single dose containers may be closely integrated into the hospital or medical environment's pharmacy system. For resuscitation situations the medications may be kept in a cart beside an existing pediatric resuscitation cart or in the pediatric resuscitation cart. Medications specifically for resuscitations and emergencies and intended to be used in conjunction with existing resuscitation systems may be sold to service the systems, as part of the systems, as accessories to the systems, or as alternatives to the systems. In a non-emergency environment such as, but not limited to, an ER with a non-emergent presentation or a wellness clinic, there may be a medicine dispensing device such as, but not limited to, an Omnicell® system, which is like an electronic cupboard or vending machine that houses and dispenses a range of medications. It is envisioned that some embodiments may incorporate a separate Omnicell® type system or a separate cupboard for weight based, pre-dosed pediatric medications, which is clearly marked as such. It is contemplated that automated medication dispensing devices with greater capacity may be implemented to dispense pre-dosed medications, as providing a separate container for each individual dose may greatly increase the spacial storage requirement. If a patient is being treated on a hospital floor or in a hospital ward, nurses often perform medication rounds with a mobile cart that may be rolled from patient to patient to administer meds to the patients as needed. It is anticipated in this situation that this medication cart may comprise clearly delineated sections or drawers for each unique weight group of medications. Alternatively, a stationary automated dispensing unit or cupboard may be present on the floor or ward.
On an ambulance it is envisioned that premeasured single dose medication containers according to some embodiments may be incorporated into a system like the Broselow Hinkle system with multiple colored pouches that correspond to weight rages and where each pouch comprises pre-dosed containers of a range of medications that may be likely to be administered on an ambulance. Due to the lack of space on an ambulance, it may be desirable for the pouches to be small enough to be non-intrusive yet contain enough medications as necessary. In some embodiments these medication pouches may be collapsible and/or foldable. A doctor's office may use any of the above described methods or combinations of methods to incorporate single dose medication containers into their practice. In some embodiments, premeasured single doses of medication may be sold over the counter. Once the general public has been educated, medications may be stocked in drug stores or pharmacies in marked boxes or containers clearly stating that the doses contained inside are for children of a specific weight only. The packaging may also comprise a unique indicia such as, but not limited to, a color or an image so that consumers can easily identify the correct dosage. To aid in this, scales may be provided near the medications to verify the weight of the child before choosing a dosage.
Those skilled in the art will readily recognize, in light of and in accordance with the teachings of the present invention, that a multiplicity of suitable products and accessories may be developed for use with some embodiments. Computer program's may be produced or updated for doctors and hospitals that uses default settings to automatically populate the appropriate dose for a patient once the medication is chosen and the patient's weight is known. For example, without limitation, if a patient is 4.3 kg and the doctor wants to order ibuprofen, the program may automatically default to a 4 kg pre-dosed syringe order. Also, medication pumps may be developed or updated specifically for use with these pre-dosed medications. Some non-limiting examples of other products that may be developed for use with systems according to some embodiments may include, without limitation, a barcode reader that may scan barcodes on medication containers and on patient wristbands or files to confirm the correct dose is being administered, color coded IV ports, scales incorporating weight group specific indicia, medication holding and dispensing machines, wristbands to identify the child to its allocated weight group and corresponding indicia etc.
All the features disclosed in this specification, including any accompanying abstract and drawings, may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
It is noted that according to USA law 35 USC §112 (1), all claims must be supported by sufficient disclosure in the present patent specification, and any material known to those skilled in the art need not be explicitly disclosed. However, 35 USC §112 (6) requires that structures corresponding to functional limitations interpreted under 35 USC §112 (6) must be explicitly disclosed in the patent specification. Moreover, the USPTO's Examination policy of initially treating and searching prior art under the broadest interpretation of a “mean for” claim limitation implies that the broadest initial search on 112(6) functional limitation would have to be conducted to support a legally valid Examination on that USPTO policy for broadest interpretation of “mean for” claims. Accordingly, the USPTO will have discovered a multiplicity of prior art documents including disclosure of specific structures and elements which are suitable to act as corresponding structures to satisfy all functional limitations in the below claims that are interpreted under 35 USC §112 (6) when such corresponding structures are not explicitly disclosed in the foregoing patent specification. Therefore, for any invention element(s)/structure(s) corresponding to functional claim limitation(s), in the below claims interpreted under 35 USC §112 (6), which is/are not explicitly disclosed in the foregoing patent specification, yet do exist in the patent and/or non-patent documents found during the course of USPTO searching, Applicant(s) incorporate all such functionally corresponding structures and related enabling material herein by reference for the purpose of providing explicit structures that implement the functional means claimed. Applicant(s) request(s) that fact finders during any claims construction proceedings and/or examination of patent allowability properly identify and incorporate only the portions of each of these documents discovered during the broadest interpretation search of 35 USC §112 (6) limitation, which exist in at least one of the patent and/or non-patent documents found during the course of normal USPTO searching and or supplied to the USPTO during prosecution. Applicant(s) also incorporate by reference the bibliographic citation information to identify all such documents comprising functionally corresponding structures and related enabling material as listed in any PTO Form-892 or likewise any information disclosure statements (IDS) entered into the present patent application by the USPTO or Applicant(s) or any 3rd parties. Applicant(s) also reserve its right to later amend the present application to explicitly include citations to such documents and/or explicitly include the functionally corresponding structures which were incorporate by reference above.
Thus, for any invention element(s)/structure(s) corresponding to functional claim limitation(s), in the below claims, that are interpreted under 35 USC §112 (6), which is/are not explicitly disclosed in the foregoing patent specification, Applicant(s) have explicitly prescribed which documents and material to include the otherwise missing disclosure, and have prescribed exactly which portions of such patent and/or non-patent documents should be incorporated by such reference for the purpose of satisfying the disclosure requirements of 35 USC §112 (6). Applicant(s) note that all the identified documents above which are incorporated by reference to satisfy 35 USC §112 (6) necessarily have a filing and/or publication date prior to that of the instant application, and thus are valid prior documents to incorporated by reference in the instant application.
