Detailed Description of the Drawings Refernng now to the drawings, Fig. 1 illustrates the hardware used in the medical product selection apparatus of the present invention. Remote computer and main computer 9 are programmed to perform the functions described herein.
10 Remote computer 10 and main computer 9 may include any type of processor or an ASIC chip, if desired. Remote computer 10 and main computer 9 (shown only for computer 10) are coupled to a display 12, an input device 16, a memory 18, and may also be coupled to a network connection 20, and a printer 14, if desired.
Also, remote computer 10 and main computer 9 may be linked to a vendor's inventory system via network 20.
In one embodiment, the selection and display functions are performed on the remote computer 10 and the data input and administrative functions are performed on main computer 9. In an alternative embodiment, all functions are performed on one computer.
In the illustrated embodiments, the input device is a touch screen on the display 12. It is understood, however, that any type of suitable input device including a mouse, keypad, control buttons, stylus, joy stick, etc. may be used in accordance with the present invention. Computer 10 is illustratively capable of being connected to the network connection 20 for receiving and transmitting information to and from other devices over a local area network, wide area network, intranet, or via the Internet.
The apparatus of the present invention provides a consumer with a list of a plurality of drug or other medical products usable to treat selected conditions and symptoms. Figs. 2a and 2b illustrate generally the steps performed to provide the list of products. Illustratively, the present invention is designed for use as a kiosk either in a pharmacy or in a retail setting that does not include a pharmacy. In another embodiment, it is understood that the system can be implemented using a computer at _7_ a remote location connected to a main computer or server by a communication network. Network connection 20 can be a dial-in connection, a LAN, a WAN such as the Internet, or a wireless network. Therefore, in one embodiment the consumer can access the system and order products from a remote location, e.g., from home.
As shown in Fig. 2a, an opening screen is illustratively displayed on display 12 to provide the consumer with options for selecting medical products. A
first option is for the user to look up specific products by name as illustrated at block 24. A second option is for the user to look up products by selecting conditions to be treated as illustrated at block 28. If the consumer selects the manual lookup at block 26, the consumer types in the name of a desired product or looks up the products in alphabetical order. The consumer can then access information such as leaflets or frequently asked questions related to the selected drug products as illustrated at block 25 and as discussed below in connection with Exhibits A-D. The consumer may also make an e-commerce purchase of a drug product as illustrated at block 27. The purchase at block 27 is particularly useful in the embodiment where the consumer accesses the information from a remote location away from the retail setting or pharmacy. In addition, an e-commerce purchase may be made at the retail setting if the particular desired drug product is not available at the store location.
Therefore, the product can be sent directly to the consumer's home.
If the user selects the option to generate a list of products based upon selected conditions at block 28, a list of conditions is then presented on the display screen 12 for the consumer to review. The consumer then chooses a condition using the input device 16. Next, a list of symptoms related to the selected condition is displayed as illustrated at block 30. The consumer chooses one or more symptoms for which treatment is desired. Next, a list of patient information categories and choices within the categories is displayed on display 12. The consumer then provides the patient information via the input device 16 related to such information as age, dosage form preferences (tablets, capsules, liquid, chewable tablets), and any known drug allergies or chronic conditions.
The computer 10 then uses the condition, symptoms, and patient information to generate a table listing all of the products available to treat the particular selected condition and symptoms as illustrated at block 34. This table, _g_ which includes all pharmaceutically equivalent products stored in memory 18, is presented on the display screen 12 for review by the consumer. The consumer can print the table on printer 14, if desired. The products are matched to the consumer's condition and symptoms and to the patient information provided by the consumer.
The consumer can then elect to look at additional information related to the selected products as illustrated at block 36. When the consumer requests additional information, leaflets related to the products or list of frequently asked questions are presented on the display screen 12 for review. The consumer can also access promotional offers or coupons associated with any of the drug products on the list as illustrated at block 38. The consumer can also select to make an e-commerce purchase as illustrated at block 39. As discussed above, the e-commerce purchase may be made from a remote location or from the kiosk at the retail store or pharmacy if the desired drug product is not available at the store. The drug product may then be sent to the customer's home location. The consumer can then either exit the system or return to the opening screen to select other conditions.
In an alternative embodiment, the user can obtain information on over-the-counter drugs, herbal remedies, vitamins, and other medical products, as shown in Fig. 2b. At block 60 of Fig. 2b the user begins the selection process and enters some basic information about himself or herself, including age and, optionally, gender.
This information does not uniquely identify the user. Blocks 62, 64, 66 and 68 represent different choices of product categories available to the user. If the user desires information on non-prescription drugs, the user selects "non-prescription" at block 62. If the user desires information on herbal or natural products, the user selects "herbals" at block 64. If the user desires information on vitamins, minerals, or other nutritional products, the user selects "vitamins" at block 66. If the user desires information on medical tests and devices, the user selects "tests and devices"
at block 68.
If the user selects non-prescription drugs at block 62, the user is taken through a series of steps illustrated by blocks 70, 80, 100, 110, and 120. At block 70, the user selects a condition for which he or she desires treatment by non-prescription drugs. Alternatively, at block 71, if the user already knows the particular medication that he or she would like information on, the user so indicates. If the user is searching for information on a specific medication, the user is prompted to enter the name of the particular medication at block 80. Once the name of the particular medication has been entered at block 80, information on that particular medication is displayed at blocks 110 and 120. If the user has selected a condition at block 70, the user will be prompted to select particular symptoms or preferred medication forms at block 100.
At block 110, a table showing the list of available products that match the user's criteria, as entered in blocks 60, 70, 100 and is displayed, allowing user to compare the available products. At block 110, the user may select a particular product for which he or she desires mare information. More detailed information is displayed to the user at block 120 for the product selected at block 110.
A similar process is performed for each of the other product categories.
At block 64, the user indicates that he or she wishes to obtain more information on herbal or natural products. At blocks 72 and 73, the user is prompted to decide whether he or she wants more detailed information on a specific known product or wants the system to help determine a suitable herbal product based on a particular condition and symptoms. If the user already knows the name of the product that he desires detailed information on as illustrated at block 73, the user is prompted to input the name of that product at block 82. Once the user has entered in the name of the particular product at block 82, information for that product is displayed to the user at blocks 112 and 122. If instead, the user would like to find a product appropriate for a particular condition as illustrated at block 72, the user is prompted to select a condition to be treated at block 90. At block 102, the user is prompted to select one or more symptoms that are associated with the condition selected in block 90.
Only the symptoms that relate to the particular condition selected at block 90 are displayed at block 102 as choices for the user to select from. At block 112, the system displays a table of all of the products matching the condition and symptoms selected by the user at block 90 and 102. From this table, the user may select an individual product on which it would like more detailed information. At block 122, more detailed information is displayed for the particular product selected by the user at block 112.
If the user selects vitamins as the category of products on which he or she would like information, he or she so indicates at block 66. The user is prompted to decide whether he or she would like specific information on a particular product at block 75, or would like to use the system to help determine a suitable vitamin, a mineral or nutritional product based on the user's needs at block 74. If the user knows the particular vitamin, mineral or nutritional product on which it would like more information, the user is prompted to enter the product name at block 84. Once the product name is entered at block 84, the system displays information about that product at blocks 114 and 124. I~ the user does not know the particular product he or she needs, the system will proceed to block 92. At block 92 the user is prompted to select a particular type of vitamin, mineral or nutritional product. At block 104, the user is prompted to select additional criteria for selecting a product, such as dosage form. At block 114, the system displays a table of all of the products matching the criteria entered by user at block 92 and 104. Viewing the table at block 114, the user may select a particular product from the table for which he or she desires more information. At block 124. the user is shown more detailed information about the particular product selected at block 114.
If the user desires information on medical tests or devices, the user so indicates at block 68. At block 78, the user is prompted to enter the category of products for which it desires information, for example, diabetes supplies or general tests. At block 94, based on his or her selection at block 78, the user is prompted to select additional criteria to help identify particular products that are most suitable for the user's needs, for example, if "tests" is selected at block 78, the user selects the type of test desired at block 94. At block 116, the system displays a table of test or medical device products which match the criteria entered by the user at blocks 78 and 94. At block 116, the user may select an individual product from the table for which it would like more information. At block 126, more detailed information is displayed for the particular product selected by the user at block 116.
Fig. 3 illustrates additional processes related to the generation of the table of products matching the condition, symptoms, and patient information input by the consumer. In the illustrated embodiments, information related to a plurality of medical products is stored in memory 18. All products stored in the memory 18 which treat the conditions and symptoms selected by the user are identified at block 40. These identified drug products are compared to drug products in the vendor's inventory which are also stored in memory 18 or in the separate inventory system 21 as illustrated at block 42. The products in the inventory can be updated manually, or automatically through the network connection 20 to inventory system 21. In one embodiment, the remote computer 10 or main computer 9 of the present invention is linked to a computerized inventory system so that remote computer 10 or main computer 9 constantly determines whether products are available within the store inventory. In alternative embodiments, either remote computer 10 is linked directly to inventory system 21 via network 20, or main computer 9 is linked to inventory system 21 and periodically updates remote computer 10. The comparison step is illustrated at block 44.
Products in the database which are not identified as treating the conditions and symptoms are not displayed to the user, as illustrated at block 46. If a product is identified as treating a particular condition or symptom, but is not available in the vendor's inventory, the identified product may either not be displayed at all or marked as not available on the table, depending upon the preference of the vendor, as illustrated at block 48. If products are identified at block 40 as treating the symptoms and conditions and are also in the store inventory at block 42, these products are included in the table of products displayed to the user and marked as available, if applicable, as illustrated at block 50. In another embodiment, the products identified at block 40 are displayed without comparing the identified products to the products in inventory.
An opening screen which is displayed by remote computer 10 on display 12 is illustrated in Fig. 4. The entry of a user name, password or other unique identification not required. The user selects the age range of the patient for whom medical product information is desired at area 130 of the display screen by clicking, selecting or touching one of the available buttons. At area 132, the user is given an option to select the patient's gender by touching, clicking, or otherwise selecting either the "Male" or "Female" button.
The user is asked to submit his or her zip code at area 134 by pressing the appropriate number buttons. However, this information is not required. In area 136, the user can choose to start over and reenter the patient information, proceed to the next display screen, quit the program, or obtain "help" information on how to use the system, by selecting the applicable button.

Fig. 5 illustrates the display screen that appears if the user selects the "Next" button at Fig. 4. Fig. 5 presents the user with the available categories of medical products. The user selects one of non-prescription medication 140, herbal and natural products 142, vitamins and nutritional information 144 and medical supplies and tests 146. The user selects the "New Patient" button in area 148 to go back to the screen at Fig. 4 and start over.
The screen of Fig. 6 is displayed if the non-prescription drug button 140 is selected at Fig. 5. The consumer can elect to look up known specific non-prescription drug products by touching, selecting or clicking on area 150 of Fig. 6. If the user already knows the name of the product, he or she is prompted to select the first few letters of the name, as shown in Fig. 7. Otherwise, the consumer proceeds by selecting or clicking a condition from those displayed on the screen of Fig.
6. An example of illustrated conditions to be selected is shown in Fig. 6. For instance, conditions may include pain, fever, headache, common cold, cough, allergy, sore throat, flu, indigestion, nausea, skin disorders, infections, foot and hand care, sleep disorders, weight gain/loss, smoking dependence, eye care and ear care.
Illustratively, these conditions are displayed on display 12 to permit the consumer to click or select a desired condition. Once a particular condition is selected at Fig. 6, remote computer 10 provides a list of symptoms corresponding to the selected condition on display 12 as shown in Fig. 8.
The consumer then selects one or more symptoms at region 154 of Fig.
8. The symptoms displayed at Fig. 8 are only those symptoms associated with the condition selected at Fig. 6. For example, illustrative symptoms for the pain, fever, and headache condition selected at Fig. 6 are shown in Fig. 8. It is understood that additional or fewer symptoms may be provided for each condition. At region 156, the user selects one or more preferred medication forms. Example medication forms include tablets, caplets, liquid, rubs, spray, and suppositories. Once the desired number of symptoms and medication forms are selected, the user clicks on or selects the "Next Screen" region at location 152 of Fig. 8.
Remote computer 10 then matches drug products stored in the memory 18 with referenced conditions and symptoms and generates a table including all available drug products for treatment of the selected condition and symptoms as illustrated at Fig. 9. ComFuter 10 deletes items from the list which may cause problems based on the known patient information. The customer can view the table on display 12 or print the table on printer 14, if desired. By providing the consumer with table of all available products, the consumer can compare the drug products to determine which drug product to select based upon ingredients and strength, side effects, warnings and cautions, dosage form, dose, pack size, pack price, price per dose, coupon availability, brand name, etc. The present invention does not eliminate products from the list unless a problem is identified based upon the particular patient information input at Fig. 4.
If the consumer selects a particular product from region 158 of Fig. 9, additional information on the selected product is printed or displayed as shown in Fig.
10. At Fig. 10, information illustratively made available to the user includes patient education sheets, frequently asked questions, and store location. A sample of additional information is illustrated in Exhibits A and C. A consumer can also display or print "Frequently Asked Questions" related to the selected drug product as illustrated in Exhibits B and D by selecting the appropriate area of the screen of Fig.lO. The consumer may also display or print a coupon for the selected product (not shown). Coupons may not be available for all of the products. Coupon availability, price, and other information related to the drug products can be stored in memory 18 of the main computer and updated regularly via the network connection 20 from main computer 9 or inventory system 21. As discussed above, the remote computer 10 may either eliminate drug products from the table which are not in the inventory of the particular vendor or store, or provide a separate column in the table of Fig.
9 which indicates the drug products that are available from the particular vendor.
Fig. 11 illustrates the display screen that is shown if the user selects the herbal and natural products button 142 of Fig. 5. If the user would like the system to help determine a suitable product for his or her condition, the user selects the "help me" button 160. If the user already knows the specific products that he or she needs and just wants more information on the product, the user selects the "I know"
button 162. If the "I know" button 162 is selected, the user is prompted to enter the first few letters of the product on a screen similar to that shown in Fig. 7. If the user selects the "help me" button 160, the user is prompted to select a condition, as shown in Fig. 12.

For example, some of the condition categories for herbal or natural products include digestive disorders, kidney or urinary, prostate, respiratory, asthma, heart, blood pressure and cholesterol, brain and nervous system, arthritis, muscles and bones, joints, skin, hair, sport supplements, sexual energy, chronic fatigue, diabetes, lip, mouth, eye disorders, and cancer prevention.

If the user selects the "help me" button 164, the user is prompted for more information about the type of product needed, as illustrated in Fig. 17. For example, the user may select single vitamins, multivitamin supplements, weight gain or loss products or information on recommended daily allowances of vitamins and minerals. The user also may select a button called "specific needs" which allows the user to identify particular needs that a particular vitamin may address. These needs are linked to a particular vitamin as shown in Fig. 31. Once the user has selected a particular type of vitamin, mineral, or nutrition product at Fig. 17, the user is prompted for additional information which will limit the selection of applicable vitamins, minerals and supplements available at Fig.
18.
As shown in Fig. 18, the user may indicate whether the particular product is needed for a specific class of individuals, such as female, prenatal, male, children, or seniors. The user may also select the particular dosage form that he or she prefers, for example, tablets, capsules, liquids, chewable tablets, or powders. Once the user completes the preferences requested at Fig. 18, the system generates a table listing the vitamin, mineral or nutritional products that match the information selected at Figs. 17 and 18.
For example, Fig. 19 shows the table that is generated if the user selects multivitamin, female, and tablets, liquid and capsules at Fig. 18.
Fig. 19 illustratively shows the composition of each multivitamin including the amount of each vitamin included in the multivitamin, the package size, the package price, the price per dose, and whether a coupon is available for a particular product. At Fig. 19, the user may obtain more information about one of the listed products by selecting or clicking on the name of the product. If the user selects a particular product for more information, a screen such as shown in Fig. 20 is presented. For example, Fig.

The NDC Code and/or the UPC Code are used to link to inventory system 21. In addition, as shown in region 210, the administrator may input or associate particular information with the product.
For example, the administrator may associate active ingredients, inactive or absent ingredients, symptoms, warnings, side effects, and patient education information with the particular product. Similar data input screens are used by the administrator to enter information about products in the other available categories, including the herbal products (Fig. 28), devices and tests (Fig. 29), tests (Fig. 30), single vitamins (Fig.
31), and multiple vitamins (Fig. 32). Except for Figs. 31 and 32, the "symptoms"
button of Figs. 28-30 is used to permit the administrator to associate particular symptoms with a product. Figs. 31 and 32 relate to vitamin products. In these screens, the "conditions" area is used to link products to specific needs of the user. If the identity of the particular vitamins is not present in the product name, the vitamin name is also specified on Fig. 31 by selecting the vitamin from a list, and on Fig. 32 by clicking or selecting the square boxes next to the name of the particular vitamins) included in the multivitamin product.
Fig. 33 displays a screen whereby the administrator associates symptoms with each particular condition. The administrator clicks or selects on symptoms listed in the right hand box on the screen of Fig. 33. For example, for the arthritis, muscle, bone, or joint condition, the "aches/restless legs" symptom may be selected. Once the administrator has completed assigning symptoms to conditions, the administrator clicks or touches the save button to record the information in memory 18. The administrator completes this process for each of the available conditions. Symptoms may be assigned to more than one condition. Also, conditions may have any number of symptoms associated with them. The linking of conditions and symptoms determine which systems will be displayed in Figs. 8 and 13 for the conditions selected in Figs. 6 and 12, respectively.
As discussed above, once a user has selected a particular product for detailed information; one type of information available is frequently asked questions.
In the illustrated embodiment, the frequently asked questions are associated with the therapeutic class of the particular selected products. Fig. 34 shows a display screen whereby the administrator may associate particular frequently asked questions with a therapeutic class. Products are assigned to therapeutic classes as illustrated at Fig. 27.
Fig. 35 shows a display screen which appears if the administrator selects the active ingredients button 186 at Fig. 25. Fig. 35 allows the administrator to add, delete or modify the information relating to ingredients, and to add new ingredients or delete ingredients that are no longer used. To add a new ingredient to the list of available ingredients, the administrator clicks or selects the add button on Fig. 35. To modify an existing ingredient, the administrator selects or clicks on the name of the ingredient to be modified. The data entry screen such as shown in Figs.
27 through 32 is then used to add, delete or modify ingredient information.
Fig. 36 shows a screen that is displayed if the administrator selects the conditions button 188 at Fig. 25. A similar process as discussed above for active ingredients is used to add, delete or modify conditions and condition information, as well as information relating to the other key words 188 through 204.
Fig. 37 shows the screen that appears if the "symptoms" button in region 210 of Fig. 27 is selected by the administrator. At Fig. 37, the administrator associates particular symptoms with a particular product. As shown in Fig. 37, all of the available symptoms are displayed in the left-hand column. In order to add or associate a symptom with the product name displayed in the upper portion of the screen, the administrator clicks or selects the particular symptom to be added and then clicks the add button in the center of the screen. When a symptom has been selected to be added, it will appear in the right-hand column of the screen. To delete a symptom that has already been selected or associated with the product, the administrator highlights the symptom in the right-hand column to be removed, and then clicks or selects the remove button. Once the symptom has been removed, it will no longer appear in the right-hand column of Fig. 37. All products linked to symptoms selected by the user using screens in Figs. 8 and 13, for example, are included in the list or display grids of products unless the product is optionally deleted from the list by checking the inventory system 21. Therefore, the customer can review and compare the entire list and make his or her own selection of the drug product based on the information presented.
One additional feature of the present invention includes the ability to allow vendors to customize the process of matching products to symptoms and conditions based on selected criterion, such as the particular prescribing preferences of the pharmacist, the vendor's marketing strategies, or according to requirements of promotional agreements. For example, a particular brand name may be configured to always be displayed first in the list of products generated for a particular combination of conditions and symptoms. Also, the present invention includes reporting features which allow vendors to track consumer usage of the system and the frequency in which different product categories are accessed.

As an example, the apparatus of the present invention may be implemented using Macromedia Director and Flash software, an Oracle database, and Lingo, SQL and HTML programming languages. However, one skilled in the art would readily understand that there are many suitable software programs and tools for developing systems consistent with the present invention.
