Surgical fluid absorbing apparatuses as well as other surgical apparatuses are used throughout an operation on a patient to aid in the facilitation of an operating procedure. Fluid absorbing apparatuses are utilized to absorb various fluids within the patient. There are various types of surgical fluid absorbing apparatuses, which can be positioned under organs deep inside a body cavity, depending upon the nature of the operation. It can be difficult to locate the various absorbing apparatuses upon completion of an operation. Difficulty in detecting the absorbing apparatuses is dependent upon the absorbing apparatus type, the location of use, and other issues associated with the operation. It is desirable to account for and remove all fluid absorbing apparatuses from within a patient upon completion of an operation.
Currently, to account for all of the absorbing apparatuses used during an operation, as each absorbing apparatus pack is opened, a nursing staff manually counts the absorbing apparatuses and hands them individually to a surgeon. As the absorbing apparatuses are used, disposed of, and new absorbing apparatuses are placed inside a body, the nursing staff tracks the total number of absorbing apparatuses used. At the end of an operation, the number of used absorbing apparatuses is compared to the number of absorbing apparatuses provided to the surgeon. When there is not a one-to-one correlation in the number used and the number of removed fluid absorbing apparatuses, time is spent to account for this discrepancy and search for the missing fluid absorbing apparatuses.
Another technique performed to account for the fluid absorbing apparatuses utilized during an operating procedure includes the use of a plastic binning process whereby five used absorbing apparatuses at a time are placed in compartmentalized plastic slots, similar to the slots of a shoe garment bag. The absorbing apparatuses are then counted and an absorbing apparatus status is determined.
A third technique that has also been performed to account for absorbing apparatuses is the use of x-ray detection. When there is a discrepancy between the number of used absorbing apparatuses and the number of removed absorbing apparatuses, surgeons may physically search the body cavity and when necessary perform an x-ray on the patient to detect the missing fluid absorbing apparatuses. Current fluid absorbing apparatuses have a radio opaque strip for identification, which is detectable and thus locatable in an x-ray.
The above-stated techniques may all be utilized during an operation. However, the locating and accounting for of absorbing apparatuses, as well as other surgical apparatuses, can be timely and costly. In general, every minute in an operating room is costly. Thus, there exists a need for an improved technique of accounting for surgical apparatuses used during an operating procedure.
In addition, to the tracking and accounting of surgical apparatuses during a surgery several other medical facility trackings and accountings, as well as identifications, are desired. For example, there is a desire to efficiently track and identify patients and to have “On-the-Spot” readily available access to patient medical histories including illnesses, medications, allergies, surgeries, recent diagnoses, scheduled surgeries, and other patient related information. Such information is not always readily available, easily accessible, or accurate especially when a patient is transferred between rooms, medical facility departments, and/or medical facilities. As another example, it is also desirous to track patient related biomaterials and medicines. As well, it is also desirable to track other medical facility materials, stock items, equipment, instrumentation, beds/gurneys, food and beverage items, and other items located within a medical facility.
One embodiment of the present invention provides a health care operating system that includes multiple health care center objects. Smart devices are attached to the health care center objects and include body internal control circuits. A database stores information related to the health care center objects. A server is coupled to the database. Multiple controllers are coupled to the server and write and/or read the information to and from the smart devices utilizing electromagnetic induction.
Another embodiment of the present invention provides a health care center network that includes health care center objects and smart devices. The smart devices are attached to the objects and inductively transmit identification signals. A database stores the information. A common server is coupled to the database. Controllers within multiple facilities communicate with the common server in response to the identification signals.
The embodiments of the present invention provide several advantages. One such advantage is a health care operating system and network that incorporates smart devices on various health care center objects, which allows for the real time, quick, and easy detecting, tracking, identifying, accounting, and monitoring of the objects and any related information. This allows for efficient assessing of the information. Also, the stated system and network allows for the maintaining of appropriate amounts and levels of the stated objects using “just-in-time” ordering and delivery techniques.

The smart tag 60 has an associated smart tag system, such as the smart device system 40. The smart tag system, is directed to patient registration, identification, history, and location detection information, as well as other known patient related information. The smart tag 60 contains a radio frequency based smart body internal control circuit 64; such a circuit is described below with respect to
The health care operating system 10 in conjunction with the smart tags provides a complete system architecture that tracks a patient from the point of admission to a hospital, medical center, or other health care center to the point of discharge. A registration system 60 is used at admission, which records currently stored database information pertaining to the patient in a smart tag, which is attached to the patient. The registration system 60 stores all prior medical procedures, correlates all biomaterials, medicines, and authorized medical procedures on the smart tag. Thus, all of the stated information is carried with the patient.
The registration system 60 includes controller/scanners (not shown for simplicity), which are similar to the controller/scanner 46 and other controller/scanners described herein. The controller/scanners are located in registration areas 62 and write the above-stated information to the smart tags 27. The registration system 60 and areas 62 are shown in
The smart tags 27 are encoded with all pertinent patient information (e.g., name, allergies, symptom) at the time of patient registration. During the patient's stay at the health care center, the smart tags 27 uniquely identify patients and any procedures or medications that are to be administered to the patients. Incorrect procedures are detected, through the use of smart software, and the proper health care center personal are notified. Smart software, in general, refers to the software utilized by any of the controllers, scanners, servers, or other devices described herein. This reduces the potential for incorrect treatment and possible complications.
The smart tags 27 may be active, semi-passive, or passive and be scanned or monitored throughout the health care center via controller/scanners described herein or other designated monitoring stations (not shown). The controller/scanners and monitoring stations may be active or passive in that they may induce or request signals from the smart tags or they may simply receive signals from the smart tags. The monitoring stations may be located anywhere within the health care center, in communication with the server 18, and have similar scanning capabilities as the stated controller/scanners. The smart tags 27 may be monitored and/or detected within a range of approximately 0-10 ft, depending on the style of smart tag, up to approximately 2 ft when passive and approximately up to 10 ft when active. The smart tags 27 may be used with health care center accounting in order to accurately account for procedures and costs associated with patient treatments, as well as “just-in-time” ordering of supplies for the health care center.
The smart label sub-system, is similar to the smart tag sub-system, however biomaterial and medicine containers, as well as various other containers, which may or may not be associated with the patient are labeled using the smart labels 29. The smart labels 29 are similar to the smart tags 27, are attached to the containers, and store information that is patient related and/or that pertains to that object and the location thereof. One or more of the smart labels 29 may be used per container. The smart labels 29 may be referred to as a form of RFID labels. The biomaterials may include blood, sputum, urine, cell samples, fluid samples, or other biomaterials known in the art. A smart label can be used on any health center container and is generally extensible to other objects including, but not limited to, clothing, bedding, wheel chairs, and other inventory items. Inventory control and location determination can be achieved through use of the smart labels 29.

RFID labeling of patients and related containers provides a correlation therebetween, which reduces the failure modes associated with incorrect container and patient mismatching. Blood type, allergies, and other patient characteristics are uniquely identified and may be stored on a smart tag and/or smart label for each patient. In addition, the treatment record and scheduled procedures of a patient may also be stored to ensure that the patient gets the proper treatment. Any smart tags and smart labels of concern may be scanned and/or information therein may be received and reviewed prior to any treatment. Smart tags and smart labels may be scanned and/or data may be received therefrom wirelessly, without the need of a manual scanning (barcode) or manual data entry system, and this data may be recorded and linked to a health care center server.
The health care operating system 10 also includes a smart docketing system 26, a smart x-ray system 28, a smart alarm system 30, and smart procedure system 32, which are all described in detail below with respect to phases two and three. The stated systems utilize the servers, databases, controllers, scanners, smart tags, smart labels, smart instruments, and smart monitoring devices described herein. The smart software, utilized in the systems, may have associated modules that correspond with each of the systems.
In general, the scanning and retrieving technology to read and write information to the smart tags 27 and the smart labels 29 is referred to as the smart docketing system 26. In one example embodiment, depending on the procedure of a patient, the smart docketing system 26 reads a smart tag located on that patient. Given the patient information, the smart docketing system 26 wirelessly writes at least a portion of the patient information onto one or more of the smart labels 29 that uniquely identifies the patient with any associated biomaterials, medicines, or surgery or patient room items.
After completion of the first phase in which health care center objects are uniquely correlated with a patient the second phase is initiated. The second phase involves the testing and recording of the patient and health care center objects in an automated method so as to reduce false patient diagnosis and treatment. The smart docketing system 26 is again utilized throughout testing, such as in testing laboratories, to quickly and efficiently scan and identify any material containers or holding elements. The smart docketing system 26 may also be used to scan and identify x-ray cartridges or the like, vial/containers, or any other health care center objects associated with a particular patient. The information obtained is then recorded using the smart software and stored and accessible through use of the health care center server 18.
The smart docketing system 26 can be used to ensure that a patient receives the proper medicine, treatment, and procedure through the use of a complete IT solution that integrates the use of smart tags, smart labels, and the smart docketing system 26. The IT solution may include the use of an Internet or Intranet system. The smart software may be accessible through the use of the health care center server 18, may be located on the server 18, may be located on any computer system, controller, scanner, or circuit within the health care center system 10 network or that is networked to or has access to the health care center operating system 10. This includes computer systems or terminals that utilize wire, powerline, and/or wireless communication.
During phase two a patient may undergo various scanning or x-ray procedures. During such scanning, x-ray cartridges or the like may be utilized, which contain x-ray images of the patient. The smart x-ray system 28 utilizes and attaches a smart label to the x-ray cartridge, which is not shown, but may be considered as one of the health care center objects. The smart x-ray system 28 scans the patient RFID and then transfers this ID to the smart label on the x-ray cartridge. The x-rays are taken and upon entry into an x-ray digitizer, the patient information is transferred to the digital imager so as to uniquely identify the x-rays with the patient. This process is especially advantageous when multiple or a batch of x-ray images are taken. X-ray films are typically processed in a batch process so that multiple x-ray images are digitized well after the patient has left the x-ray lab. Consequently, this system improves the accuracy of patient-film matching, as well as improves the efficiency of the imaging process. Once an x-ray cartridge has been removed from a digitizer and the x-ray data contained therein has been stored, the cartridge RFID may be erased and reused for the next patient.
After a treatment and/or procedure has been determined the third phase may be initiated and the treatment and/or procedure is performed. Another sub-system, referred to as the smart procedure system 32, is utilized and includes the use of the smart alarm system 30, the smart monitoring devices 31, and the smart instruments 33. Although the smart alarm system 30 is described primarily with respect to the third phase, it may also be used in other phases and in a different capacity.
The smart instruments 31 include surgical fluid absorbing apparatuses, as well as other surgical apparatuses that may be used throughout an operation of a patient. Some of the instruments 31 may be used to aid in the facilitation of an operating procedure. The smart instruments 31 also include a radio frequency circuit, which may be similar to that used on the smart tags 27 and the smart label 29. Each smart instrument 31 may store data associated with the procedure being performed, as well as patient identification information.
The smart instruments 31 may include fluid absorbing apparatuses, surgical equipment or tools, and other instruments known in the art. Surgical equipment may include for example a scalpel, a retractor, a pair of pliers or tweezers, or other known equipment.
The smart monitoring devices 33 may also be in the form of equipment and are used throughout and monitor a treatment or operating procedure. The smart monitoring devices 33 may include RFID labels or controllers that have stored patient and procedure identification information and additional logic. The additional logic may be used to monitor the operation of the smart monitoring devices 33 and other procedure parameters. The smart monitoring devices 33 may include and/or monitor, for example, the operation of pumps, ventilators, EKGs, sequential compression devices, the blood or medication being administered, fluid flow rates, and other devices and parameters. The smart monitoring devices 33 may monitor the procedure being administered and the use of the smart docketing system 26 to wirelessly scan a smart tag of a patient to determine whether the procedure is appropriate and is being administered accurately, as well as to determine whether associated parameters are within desired, predetermined, or recommended ranges. Proper and accurate medications and procedures are enabled through the use of the stated devices.
The smart alarm system 30 is generally used as part of the operating system 10 to alert health care center personnel when an instrument is missing, when a treatment and/or procedure is being improperly administered, or a parameter error exists. Utilizing RFID tagging and labeling, the smart alarm system 30 is employed to ensure that the patient receive the appropriate care that has been prescribed for that patient. Patient rooms, operating rooms, or medical treatment areas are instrumented with RFID scanning technology, which supports the reading of the stated information. Upon reading the RFID information concerning the patient from the smart tags 27, smart labels 29, smart instruments 31, and smart monitoring devices 33 in the collocated treatment area, an alarm signal is generated when a discrepancy is observed. The alarm signal involves several components that involve audible and visual warnings. An alarm signal may be sent to the assigned doctors and/or nurses in charge or any support personnel listed in the alert database.
As an example use of the smart procedure system 32, prior to an operation, a surgical tray may be scanned whereby each instrument on the tray is identified and stored into a smart instrument database, such as one of the databases 330, shown in
Tracking and accounting for all surgical equipment reduces costs and improves operating room efficiency. This wireless technological breakthrough not only helps to automate and improve operating room efficiency but it helps to reduce follow-up surgical treatment for unaccounted for instruments.
The above-stated technology may also be used to track health care center objects that are unrelated to a particular patient. The stated technology may be used in shipping and receiving, in stocking of objects, or in other areas of a health care center. For example, in shipping and receiving areas supply and inventory databases may be updated accordingly with respect to any object that is leaving from or arriving to the health care center.

The absorbing apparatus 132 may be in the form of a cloth, a sponge, a towel, a pad, a swab, or other fluid absorbing apparatus known in the art. The absorbing apparatus 132 may be formed of various materials, such as cotton, gel, foam, thermoplastic, synthetic resin, natural rubber, synthetic rubber, cellulose, and nylon, or may be formed of some other material or material composite known in the art. The absorbing apparatus 132 may be packaged in groups, such that more than one fluid absorbing apparatus is contained within a single package. In one embodiment of the present invention, the fluid absorbing apparatuses are packaged in groups of five, as is shown in
The smart control circuit 134 includes a transponder 136 and a logic circuit 138. The transponder 136 and the logic circuit 138 may be encased within a hypoallergenic casing, as is designated by dashed lines 140. The casing 140 is attached to a radio opaque marker or strip 142. The transponder 136 allows for communication transfer of the identification information stored in the logic circuit 134. The hypoallergenic casing 140 is used to prevent allergic reactions. During production of the smart device 130 the logic circuit 134 and the transponder 136 are mounted on the backing board 144, encased in the casing 140, and attached to the strip 142.
The transponder 136 may be in the form of an antenna and used to receive inductively generated identification signals containing identification information. The identification information may include an identification number or code that is designated for that particular smart device. Before use of the smart device 130 in an operating procedure, the identification information may be stored on the logic circuit 134 and periodically scanned to perform an accounting of all fluid absorbing devices used during that procedure. The term “accounting” refers to the difference between the number of fluid absorbing devices actually in use and the number of fluid absorbing devices accounted for, which includes the fluid absorbing devices that are registered for use, are in use, and have been removed and/or discarded after use.
The logic circuit 134 may be a solid-state silicon based circuit or may be in some other form known in the art. The logic circuit 134 may be read or written to using radio frequencies. The use of radio frequencies to communicate identification information regarding smart fluid absorbing devices may be referred to as radio frequency identification (RFID) or inductive transponder technology.
The backing 144 may be formed of a high temperature resilient material such that it is capable of withstanding temperatures required for sterilization. Sterilization temperatures for fluid absorbing devices can exceed 105° C.
Although a hypoallergenic casing is utilized, other casings may be used. The hypoallergenic casing 140 may be attached to the strip 142 via an adhesive, may be stitched to the fluid absorbing apparatus 132 or the strip 142, or may be attached using some other attachment technique known in the art.

The wands 152 and 154 may be in the form of mobile handheld devices or may be in the form of stationary scanning devices. The serial coupled wands 152 are electrically coupled to the associated inductive controller 158 via serial connections 160. Each of the wireless wands 154 contains a wand transponder 162 that is in wireless communication with an inductive controller transponder 164 of the associated inductive controller 158.
The main controllers 156 and the inductive controllers 158 may be desktop or laptop configured or may also be in the form of handheld devices. In one embodiment of the present invention, the main controllers 156 are desktop configured and the inductive controllers 158 are handheld configured.
The main controllers 156 and the inductive controllers 158 may be microprocessor based such as a computer having a central processing unit, memory (RAM and/or ROM), and associated input and output buses. The main controllers 156 and the inductive controllers 158 may be in the form of application-specific integrated circuits or may be formed of other logic devices known in the art. The main controllers 156 and the inductive controllers 158 may be a portion of a central main control unit, may be combined into a single controller, or may be stand-alone controllers as shown.
The wands 152 and 154 transmit and receive the identification information to and from the logic circuits 134 located on the absorbing devices 130. The wireless configuration of the wands 154 simplifies the registration and deregistration process of the absorbing devices 130 by removal of the serial connections 160.
The wands 152 and 154 and the inductive controllers 158 may be in the form of low-power non-disruptive inductive devices that transmit and receive short messages. As such, the wands 152 and 154 and inductive controllers 158 do not affect a body of interest being acted on and also do not affect equipment utilized in the operating procedure. Since the accounting systems 150 and 150′ are inductive no power sources or toxic materials are utilized inside the body to enable communications between the wands 152 and 154 and the control circuits 134.
Although radio frequency identification with inductance is utilized, the accounting systems 150 and 150′ may be modified to support long-range detection for activation, registration, and deregistration of absorbing devices.

The server 18 and the database 20 may be centrally located and within one of the hospitals 172. The smart database 20 contains identification information related to the smart absorbing devices 130 utilized in each operating room 174, which may be archived and retrieved at a future date. The database 20 may store information such as surgery type, number of smart absorbing devices 130 accounted for and used, and any other pertinent information to safe guard the accountability of the smart absorbing devices 130. The database 20 may also store a proposed or recommended radio frequency identification technique to be used in a particular operation such as for surgical equipment or tools. The database 20 may be accessed by hospital administrators and may be access limited to a certain set of hospital administrators.
The remote diagnostic system 24 ensures that the accounting network 170 and any accounting systems, such as systems 150 and 150′, function reliably. The remote diagnostic system 24 allows for remote administration of each hospital 172 and operating room 174. Remote administration provides a reliable real time surgical technique for management and accountability of smart absorbing devices. The diagnostic system 24 may also enable routine software upgrades and system performance enhancements. A technician may remotely access the accounting network 170 and determine the current status of the accounting network 170 and of any absorbing devices and accounting systems utilized therein. The remote diagnostic system 24 may be in direct communication with the server 18, as shown, or may be in communication via the Internet 22.
The server 18 the database 20, the Internet 22, the remote diagnostic system 24, the hospitals 172, and the operating rooms 174 may also communicate to each other wirelessly, via wire, or via powerlines. The server 18 the database 20, the Internet 22, the remote diagnostic system 24, the hospitals 172, and the operating rooms 174 may also communicate between each other through the server 18, through the Internet, or directly as desired. In one embodiment, all communication is performed through the server 18 such that the database 20 is continuously updated accordingly.

In step 200, the smart fluid absorbing devices 130 that are to be stored and tentatively utilized during the operating procedure are activated. The absorbing devices may be activated via the wands 152 or 154. In
In step 201, a smart fluid absorbing apparatus detection and accounting system, such as accounting systems 150 and 150′, is used to register each fluid absorbing device 130 prior to use during the operating procedure. A wand, such as one of the wands 152 or 154, is passed over the package 182 and/or each of the fluid absorbing devices 130. The fluid absorbing device package 182 may be passed over or near the wand when the wand is in a stationary configuration.
The main controller 156 or inductive controller 158 assigns a unique identification (ID) for each absorbing device 130 and programs or writes that identification to each of the logic circuits 134. The ID can include an operating room number, surgical lead, patient name, operation type, an absorbing device number, as well as other identification information. In a simple example embodiment, a serially increasing fluid absorbing device number may be used as the ID.
In step 202, the absorbing devices 130 are placed within a storage unit or bin 184. The absorbing devices 130′ within the bin are registered. The bin 184 may be compartmentalized, as shown. Each compartment 186 may correspond to a particular type of absorbing apparatus. In step 204, the absorbing devices 130′ are removed from the storage unit 184 as desired for use during the operating procedure.
In step 206, as the absorbing devices 130 are used and removed from the body they may be returned to the storage unit 184 and scanned or they may be scanned and then disposed. Each absorbing device 130 is queried and read after the operating procedure. The absorbing devices may be queried during the operating procedure when it is desirable to dispose of an absorbing apparatus. The same wand may be used to query the absorbing devices during and after the operating procedure as that used to register the absorbing devices before the procedure.
In step 208, the main controller 156 compares the number of absorbing devices 130 that were registered and placed within the storage device 184 before the procedure with that existing in the storage device 184 during or after the procedure to assure that none of the absorbing devices 130 are unaccounted for or remain in the body cavity. When there exists a discrepancy between the number of absorbing devices registered and the number of absorbing devices existing during or after the procedure, the main controller 156 indicates to an operator, administrator, or other individual the discrepancy. Query time using the above-described technique is significantly reduced over that of prior techniques. Reduced query time reduces costs involved therein.
In step 210, when one or more fluid absorbing devices are not detected in step 208, but has been assigned as “used” during registration, the main controller 156 alerts the surgical team performing the operating procedure of the missing devices and there identification information. The surgical team may then proceed to perform an extensive search of the body to locate the missing absorbing devices. The accounting system utilized may message, request, or alert hospital staff for assistance. This messaging may be in the form of a text message. An administrator may initiate the alert.
In step 212, the missing absorbing devices are detected and location thereof is determined. In step 212A, the wand is used to detect the missing absorbing devices. The wand may be used to isolate the absorbing device within the body. Once detected the absorbing devices are removed.
The accounting system 170 may be configured to scan the storage unit 184 autonomously, in the form of a deregistration. Autonomous deregistration increases efficiency of the accountability procedure. When the absorbing devices are not stored within a storage unit, a manual deregistration process may be utilized. At the end of the operating procedure the absorbing devices that were initially registered for the operating procedure are compared to those deregistered. It may be the case that not all absorbing devices registered are used. Consequently any absorbing devices not used in the operation are deregistered and disposed. The disposal satisfies sterilization procedures.
In step 212B, an x-ray of the body may also be performed to detect the missing absorbing devices as desired. The opaque strip of the absorbing devices may be detected through the use of an x-ray machine.
In step 214, when all of the absorbing devices registered are accounted for the main controller 156 indicates such to the operating team. Any missing absorbing device alerts are deactivated and operating room data is stored in a database, such as the database 20.
The alerts in steps 210 and 214 may be audio and/or video in nature. The alerts for a missing absorbing device may have an alarming sound and/or visual graphic warning indication. The alert that all absorbing devices registered are accounted for may have a pleasant sound and/or visual graphic indication.

In step 250, the body cavity is scanned using as an example one of the above-described wands and accounting systems. In step 252, when an absorbing device is detected the accounting system reads the identification information stored on the control circuit of that absorbing device and generates an identification signal. In step 254, an x-ray of the body cavity may also be performed to further aid in the detection and location determination of the absorbing devices.
In step 256, an accounting system, such as one of the accounting systems 150 and 150′, generates an identification signal in response to the identification information and indicates to the operating team the detection of the absorbing device and any related identification information.

The inventory infrastructure 16′ also includes a biomaterial inventory 374 and a biomaterials database 376. A biomaterial inventory 374 includes the biomaterials of each patient and other biomaterials. The biomaterials are stored in various containers each having a smart label. A biomaterials database 376 may be utilized to store biomaterial related information and inventory status of the biomaterials 374. The biomaterials may be associated or assigned with patients or may be in the form of a stored inventory supply, which is to be assigned.
A diagnosis and treatment entry device 378, such as device 328, may be incorporated into the inventory infrastructure 16′ for the entering of data related to a diagnosis or treatment, as well as for other patient, inventory, and health care center related information.
A doctor/nurse database 380 is also included and stores doctor and nurse information and identification associated with each treatment and procedure and for each patient. For example, the names of the doctors and nurses that were assigned and that actually performed a particular treatment or procedure for a particular patient is stored and associated therewith for future access.
A medicine and supplies inventory 382 is further included along with an associated database 384. The containers within the supplies inventory 382 also have RFID labels. The medicine and supplies database 384 operates in conjunction with the medicine and inventory communication system 356. The medicine and supplies may also be associated or assigned to patients or may be in the form of a stored inventory supply, which is to be assigned.
The inventory infrastructure 16′ also includes a billing system 386. The billing system 386 performs accounting services associated with each patient based on treatment and procedures performed, lengths of stay, medicines administered, supplies utilized, as well as other accounting factors known in the art. The billing system 386 may prepare bills based on the stated information.
The internal purchasing and inventory database 364 may include data contained in databases 370, 372, 376, and 384 for determining medicine and supplies needed for future treatments and procedures. The purchasing and inventory database 364 operates in conjunction with the medicine and inventory communication system 356 and the medicine and supplies database 384. The databases 364, 370, 372, 376, 380, and 384 may be separate as shown or combined into a single database. Automatic ordering of materials and supplies may be performed in response to the recorded inventories.
The medicine and inventory communication system 364 and the inventory infrastructure 16′ provide efficient ordering and stocking of materials and supplies and provide just-in-time delivery, which reduces inventory size, while maintaining proper supplies.
