DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and system for managing medical devices used in hospitals and medical laboratories.

[0002]

2. Description of the Related Art In medical institutions such as hospitals and medical laboratories, various medical tools are used for surgery and medical examination. This is, for example, a device including a device, a medicine, an implant device (thing to be implanted into a patient by surgery: an intraocular lens, a pacemaker, a prosthesis, etc.). At medical institutions, these various tools are supplied by manufacturers, some are stocked at medical institutions, and some are ordered as needed.

[0003]

However, in medical institutions, inventory management of medical devices is very complicated because it is difficult to predict the timing of use and there are many types. One of the reasons is that the onset of a patient is generally sudden, the demand is difficult to predict, and it is difficult to perform planned management. On the other hand, in the medical field, there are often time-sensitive operations and tests. Therefore, building a rapid supply system for medical devices is an extremely important issue. This is a problem unique to the medical field.

[0004] In particular, some implant tools and chemicals also deteriorate over time, so long-term stocks are unsuitable, and medical institutions cannot keep long-term stocks.
Frequent orders are required each time they are needed.
Manufacturers also need detailed production control and prompt supply, anticipating demand.

[0005] An example of an implant device that deteriorates with time is an intraocular lens (including an intraocular contact lens as well as a normal intraocular lens) used in eye surgery. The hospital where the surgery is performed selects and uses a lens suitable for the patient's eye. However, intraocular lenses to be used have various sizes and shapes corresponding to individual differences of patients, and necessary ones are not always stocked in hospitals. Furthermore, when the size and shape of the patient's eye are peculiar, there may be a situation where there is no stock in the lens manufacturer. In the case of timely eye surgery, supply delays are not allowed.

The present invention has been made by recognizing the above-mentioned problems unique to the medical field. The main object of the present invention is that demand forecasting is difficult and quick supply is required,
To solve the problem of supply of medical devices by establishing new methods and systems.

[0007] One of the more specific objects of the present invention is to provide a method and system capable of promoting timely product development / improvement and after-sales support of a medical device using a communication network.

[0008] One of the more specific objects of the present invention is to provide a method and system capable of supplying medical devices in a timely and efficient manner using a communication network.

[0009] It is a further object of the present invention to provide a method and system that enables a manufacturer of medical devices to efficiently perform delivery and production management using a communication network.

A further object of the present invention is to provide a method and a system capable of providing a good after-sales service of a medical device using a communication network.

[0011] It is a further object of the present invention to provide a method and system which can reduce the shortage of medical devices by using a communication network.

[0012] Further objects of the present invention will become clear in the description hereinafter.

OL) is taken as an example, but the present invention is not limited to this, and can be applied to other implant devices (such as those that are worn on the human body such as pacemakers, prostheses, artificial roots, and artificial bones). Further, the present invention can be applied to medical devices that need to be selected appropriately for individual patients, for example, medical devices such as dedicated devices used for mounting surgery of the implant device, pharmaceuticals, and consumables used for examination and treatment. .

FIG. 1 shows an information communication network including a medical institution such as a hospital or a medical research laboratory, and a supplier of medical equipment used in the medical institution (a company organization including a manufacturing section, a sales section, a distribution section, etc.). FIG. 2 is an overall configuration diagram. Largely, there are Hospital A (1), Hospital B (2), Medical Laboratory (3), Lens Supply Company (4) (Medical Equipment Supplier), which are connected via the Internet (5). It has a configuration.

In the hospital A (1), an in-hospital LAN (10), which is a local area network, is constructed, and each medical department is a department A (11), a department B (12), a department C (13), Department D
The computer equipment and medical measurement equipment of (14) are connected to a network. General hospitals include departments in various fields. Taking the ophthalmology field as an example, as a medical measurement instrument, an auto-refractometer that measures eye refractive power, a keratometer (corneal curvature measuring device) that measures corneal refractive power, and an ultrasonic eye axial length measuring device that measures the axial length of the eye A variety of devices, such as a visual acuity meter to measure eyesight, a digital fundus camera to capture fundus images, a fundus blood flow meter to measure fundus blood flow velocity, a perimeter to measure the visual field, and a tonometer for tonometry is there. This hospital LAN (10) has an electronic medical record system (1
5), the hospital stock management system (16) is connected. The electronic medical record system (15) has a server including a database for digitizing and managing medical record information of all patients handled in each department, and is accessible from each medical department in a client / server format. The medical record information is specifically, patient's personal identification data (ID code, name, etc.), examination / treatment record (date, examination contents, examination data,
Information such as findings by doctors, treatment details, and medical equipment used). Here, the medical device is a device including a device, a drug, and an implant device. FIG. 9 shows an example of a user interface of the electronic medical record, in which the above-mentioned medical record information is displayed.

The in-hospital stock management system (16) has a server including a database for managing the stock status of medical devices used in the hospital. Inventory management manages medical devices by product serial codes. Hospital stock management system (16)
Are accessible from the medical departments of the hospital and the inventory management department of the hospital in a client / server format. Also, as described below, the supplier of the medical device is conditionally permitted to access the in-hospital inventory management system (16) via an external network. The treating physician or his / her assistant accesses the in-hospital inventory management system (16) from the department's access terminal (PC or workstation) to check whether medical equipment necessary for treatment or examination is stored in the hospital. You can check the stock.

Similarly, in the hospital B (2) different from the hospital A (1), the department A (21), the department B (22), the department C (23), the electronic medical record system (25), the in-hospital inventory management. The system (26) and the like are networked by the hospital LAN (20). The details of the electronic medical record system (25) and the in-hospital inventory management system (26) are the same as those described for the hospital A (1). Hospital A
The difference from (1) is that a more local service providing system 24 is connected to the hospital LAN of hospital B (2). As will be described later, this service providing system includes a server for providing an appropriate medical device selection support service based on patient information, and can be accessed from each department of the hospital B in a client / server format.

Also, in the medical laboratory (3) different from the hospital A (1) and the hospital B (2), the department A (3)
1), a department B (32), and a department C (33) are networked by a local LAN 30. An inventory management system (35) and a database system (34) for storing research data are connected to it, and each department can access it in a client / server format.

The lens supplier (4) is an example of a supplier of a medical device, and is a supplier of an intraocular lens for a medical operation, which is an example of an implant device. As described above, within the scope of the present invention, there are suppliers of other implant devices (for example, pacemakers, prostheses, artificial roots, artificial bones, etc.), pharmaceuticals, and consumables used for inspection and treatment. You may. A sales department (41) (including sales and distribution), a development department (42), and a manufacturing department (43), which organize a lens supplier (4), are networked by an in-house LAN (40). There, in-house inventory management system (44), online ordering system (45), lens selection service providing system (46)
Is connected. The in-house inventory management system (44) has a server including a database for managing the inventory status of all products handled by the lens supplier. Online Order System (45)
Has a server that accepts online orders for products from medical institutions (1.2.3), which are customers, via the Internet (5). The service providing system (46) has a server that provides a service for assisting the customer in selecting a lens suitable for a patient, and provides an online service in a client / server format. The specific contents of these services will be described later.
Each of the online ordering system (45) and the service providing system (46) has a storage device (hard disk or memory) for storing a computer program or a data group of a database that defines service procedures in terms of hardware, and executes the program. (Processing unit), and a network interface connected to the LAN.

Instead of executing all the service function programs on the server side processor, instead of executing a program that defines a part or all of the service functions (and, if necessary, database data), the client (service use). The function may be performed by the processor on the client side. In this case, the program executed on the client side may be either a method of transferring the program from the server to the client via the network, or a method of previously installing the program as service use software in a storage device of the client. Considering a quick update of the service, it is preferable to use an applet format, which is downloaded from a server to a client via a network every time the service is used and executed on the client side.

Hospital A (1), Hospital B (2), Medical Research Institute (3),
Each LAN of the lens supplier (4) is connected to the Internet via a gateway including a firewall.
Connected to (5). In order to protect the privacy of patients and hospitals, robust security functions are essential when using the public Internet. It uses a security system that uses encrypted data communication and a user ID and password. If you want to completely eliminate the possibility of third party intrusion, use a dedicated communication line (6) for data communication between the lens supplier (4) and the hospital (1) without going through the Internet. You may use it.

Each server (46, 45) for providing an online ordering service and a lens selection support service managed by the lens supplier (4) is connected to the LAN (40) in the lens supplier.
Instead of placing it on the rental server (7) provided by a third party on the Internet, it may be placed on the rental server (7). In this case, the lens supplier (4) performs program correction and data transfer via the Internet (5), and remotely manages the contents of the rental server (7).

The above is the description of the hardware network configuration. Next, specific service contents and procedures will be described.

FIG. 2 is a flowchart of a standard procedure in a medical institution (hospital A, hospital B, or medical research institute) using the present service system. There are various sizes and shapes of intraocular lenses corresponding to individual differences of patients. Therefore, in each department, a doctor, a laboratory technician, or his assistant needs to perform an operation for selecting an intraocular lens suitable for a patient. The lens supplier uses a variety of information about the lenses owned by the company to provide support services for selecting a lens suitable for a patient.

In step 101 (log on to the service) in FIG. 2, a doctor, a laboratory technician, or an assistant in each department of the medical institution transmits a service using terminal (PC or workstation connected to the network) at hand to the in-hospital LAN. And access the service provider server of the lens supplier via the Internet. Enter the user code and password individually assigned to the service user and press the button for the desired service content. Only registered users (hospital A or individuals) can log on. As shown in FIG. 4, there are two service content options, “lens selection support” and “online order”.

Step 102 (input of patient data) and subsequent steps are steps when the lens selection support service is selected. The patient information for performing the operation for mounting the intraocular lens is input. FIG. 5 shows an input screen displayed on the service using terminal. Input data items include patient ID, keratometer
Kerato value (corneal refractive power) measured by (corneal curvature measurement device), eye axis length measured by ultrasonic eye axis length measurement device, postoperative refraction value of patient's eye after insertion of intraocular lens , Corneal diameter, pupil diameter, naked eye acuity, corrected acuity, corrected sphericity, astigmatic refraction, and astigmatic axis angle. In addition, there are selection items for the type of lens (CAT, PHAKIC) and insertion position (anterior chamber, posterior chamber) for the interior of the eye. These data are automatically imported from the patient's electronic medical record via the hospital LAN and displayed on the screen. Displayed above. The data acquisition from the electronic medical record is performed by a hospital network access program incorporated in the service using terminal. Items for which there is no data in the electronic medical record are displayed as blanks, and the doctor inputs numerical values from the keyboard of the service using terminal as needed. Also, if the doctor wants, the numerical value of the input item can be rewritten to a value different from the numerical value taken from the electronic medical record. At the lower part of the screen, an execution button for “applicable lens search” is displayed. When this button is clicked, the process proceeds to the next step 103. In addition, a “parameter customization” button is also displayed so that the user can customize a parameter serving as a lens selection reference.

In step 103 (matching lens search), according to the patient data received via the Internet, the lens selection service system searches for an appropriate intraocular lens according to the selection criteria. The procedure is as follows. First, an appropriate lens power for the patient's eye is calculated.
This utilizes a known lens power calculation formula for selecting a lens power known in the ophthalmic medical community. One example is the SRK / T formula. For more information on the formula, see John A. Ret
zlaff, MD et al: LENS OMPLANT POWER CALCULATION (T
hird Edition), SLACK Incorporated. Also SRK
Various lens power calculation formulas other than the / T formula, such as Binkho
There are rst formula, Colenbrander-Hoffer formula, Regression formula,
These can be used instead of the SRK / T formula.

The parameters used in the SRK / T equation include a parameter called an A constant, which is specific to the type of intraocular lens. There are also other parameters such as anterior chamber depth. These parameters may need to be changed slightly depending on the manufacturer of the intraocular lens. The recommended values of the parameters are usually provided by the lens supplier, but the numerical values may be changed depending on the judgment of the individual doctor, which corresponds to so-called doctor's know-how. In order to enable customized use of doctors,
In step 102, when the user presses the "parameter customization" button, an input item for inputting a value different from the manufacturer's recommended value for the value of the A constant described above appears, and the user enters the numerical value there. The input can be used to calculate the lens power. The value of the A constant used for calculating the lens selection is automatically recorded in the lens selection service system. As will be described later, the average value of many users is calculated, and this is used as a recommended A constant value. Usually, this value is used to calculate the lens power.

When the lens selection service system obtains the lens power by the above formula, the value is used as a search condition, and further, other patient data such as corneal diameter data and pupil diameter data are used as another search condition, and all the search conditions are used. Search the database to select the ones that meet. That is, from the various types of intraocular lenses stored in the database,
<Condition 1> Lens type having calculated lens power,
<Condition 2> A lens that satisfies both the conditions of the patient's corneal diameter data and the lens suitable for the pupil diameter data is searched and extracted. As a result of the search, all the models of the intraocular lens whose specifications of the lens power and the optical part diameter match are selected. The database of the lens selection service system of this example includes not only models of one manufacturer (own company) but also data of various models of intraocular lenses of multiple manufacturers, and searches for compatible intraocular lenses regardless of the manufacturer. can do.

In step 104 (search result display), the results of the search are listed up and displayed on the service using terminal. FIG. 6 is an example of a search result displayed on the screen of the service using terminal. In this example, lenses of different manufacturers that match the search conditions are also displayed in the list, but only a model of one specific manufacturer (own company) may be displayed. Further, whether or not each selected intraocular lens is in stock is displayed. The inventory is confirmed by the service providing system (46) accessing the in-house inventory management system (44) via the in-house LAN (or via the Internet if the server is a rental server). Looking at the search result, the doctor finally decides which lens to use. The doctor opens the patient's electronic medical record and records the selected lens model, lens power, predicted refractive power after insertion, lens characteristics, and the like in the electronic medical record.

If the doctor does not agree with the search result when he / she presses the "re-search" button on the screen shown in FIG.
Return to the patient data input screen of
Alternatively, the search can be performed again by slightly changing the selection parameter. If the patient's eye is special and an appropriate lens cannot be found with a standard lens, an order can be placed to manufacture a custom-made product at a factory as described later.

In step 105 (online order),
Provides a service that accepts orders for intraocular lenses online. This service is led by a local server in the hospital and works in cooperation with the online ordering service system (45) of the lens supplier. The server location is transparent to the service user.

If an online order is to be made immediately after the search for the lens selection service, the "online order" button is pressed on the search result list screen shown in FIG. Then, the screen shifts to an online order screen as shown in FIG. On the screen, four input items of manufacturer, model name, power, and order quantity are displayed, and a plurality of orders (order 1, order 2, order 3, ...) are displayed.
·)It can be performed. Usually, the search result of the lens selection service is automatically input and displayed for each item. The user deletes items and designates only those which he / she wants to order, leaving unnecessary ones out of those. After the specification, click the “OK” button at the bottom of the screen,
The screen shifts to the order confirmation screen as shown in. When "online order" is selected in the service selection in the first step 101 (FIG. 4), a new order can be made by directly jumping to the order screen shown in FIG. In the case of a new order, the input items are displayed blank, so enter the desired item in one or more of the items of manufacturer, model name, power, and order quantity (operability is improved by making it possible to select from the pull-down menu) Then, if "OK" is pressed, a list of models matching the conditions is displayed as shown in FIG.

FIG. 8 shows a final confirmation screen of the online order displayed on the service using terminal. Whether or not each intraocular lens is in stock in the hospital and whether or not it is in stock at the manufacturer are also automatically checked and displayed on the right side of the screen. The number of stocks may be displayed as a number instead of the presence or absence of stocks. Data on the hospital stock is provided from the hospital stock management system (16, 26, 35), and data on the maker stock is provided from the maker stock management server 44. The service user confirms the displayed contents and clicks “order” to complete the order. Click Cancel to cancel the order.

The subsequent processing of the intraocular lens ordered by the online ordering system differs depending on whether the intraocular lens is in stock in the hospital or not. For items that are in-hospital in-hospital, the in-hospital inventory management system records the ordering item, the orderer, the ordering department, and the like, and the in-hospital inventory management department delivers the intraocular lens according to the time and place of the patient operation. If there is no stock in the hospital, an order is automatically made to the online ordering system (45) of the lens supplier via the Internet.

In step 106 (lens supply), if the ordered lens is in-hospital stock, immediately or at a necessary time from the in-hospital inventory management department,
It is delivered to the doctor who performs the surgery. For orders placed outside the company, the sales department or distribution department of the lens supplier supplies it to the in-hospital inventory management department, registers the product serial number in the in-hospital inventory management system, and sends a doctor's request when necessary. Delivered to

In step 107 (treatment / surgery for the patient), treatment such as treatment / surgery for attaching the lens to the patient is performed using the supplied intraocular lens.

The treating physician or his assistant makes a final on-site confirmation using a fail-safe system that the intraocular lens used is indeed the one selected for the patient. This procedure will be described. As shown in FIG. 10, the product package enclosing the intraocular lens is labeled with a bar code printed with a product serial code (identification code composed of numbers and symbols) that differs for each shipped product. ing. The product serial code includes three types of information: a code for identifying a model name, a serial number (a different serial number for each model even if the model is the same), and lens power. On the label, the model name and lens power are written in characters so that humans can visually recognize it. When opening the package, a doctor or assistant visually checks the label description. At the same time, the barcode on the package is read by the barcode reader of the operation terminal at hand in the operating room. The operation terminal displays the lens model name and the lens power included in the barcode. At the same time, the operation terminal checks the model of the intraocular lens and the lens power of the product serial code read by the barcode by collating with the patient's electronic medical record through the in-hospital LAN. The lens model and the lens power input are checked to see if they match. Then, the operation terminal presents that the collation has been matched by a display on a display or a voice of a speaker. After confirming that, the doctor starts the operation. Such a pre-operative fail-safe system obviates the possibility of a human error by mistake in mounting the intraocular lens.
As a specific example of the operation terminal, operability is good when a handy terminal with a built-in computer connected to the hospital LAN through a wireless or other network interface is used. Further, a laptop PC or a desktop PC having a network interface may be used.

In step 108 (update of the electronic medical record / selection criteria), the patient data on the electronic medical record is updated. The product serial code read by the bar code of the operation terminal during the operation is automatically recorded in the patient's electronic medical record. At the same time, the product name and type of the intraocular lens, the date of use, and the name of the doctor in charge (user code) are automatically recorded in the electronic medical record. After the surgery, the physician comments on the use of the intraocular lens (including quality and claim information)
If input from the operation terminal or another terminal, it is also recorded on the electronic medical record. Immediately after or after the operation, the patient's eye is measured by various measuring devices to check the progress after the operation, and the measured data is also recorded in the electronic medical record via the in-hospital LAN.

Further, a part of the information recorded in the electronic medical record, ie, a part of the measurement data, and information such as a product serial code of the intraocular lens inserted into the patient's eye, date of use, place of use, form of use, and the like. Is provided to lens suppliers via the Internet. Of these, information on inventory is recorded in the database of the in-house inventory management system of the lens supplier. Further, after the operation of mounting the intraocular lens, an entry form for inputting patient information called a patient card is given to the patient from the hospital, and the product serial number is also printed on the patient card. If the patient fills in this patient card with personal information and impressions and opinions after use and returns it to the intraocular lens supplier, the supplier enters the data written on the card and associates it with the product serial number and Record in the database. In the lens selection support service system on the lens supplier side,
Based on the received measurement data, the A constant of the above-described lens power calculation formula (SRK / T formula) is recalculated and automatically updated in association with the lens type. The specific method is as follows.

It is assumed that a certain patient uses the nth service. The measurement data of the patient: naked eye refractive power = D ₀ , corrected refractive power = D are transmitted from the hospital. When the initial setting A constant which is a manufacturer recommended value = A ₀ , the value of the A constant calculated using the above D ₀ and D = A ′, and the lens power of the used intraocular lens = P, the A constant is as follows: It is updated like
It should be noted that the constant A ₀ of the initial configuration is working with weights with 1000 persons, but that number may be changed. Method of updating the A value at the n-th time: (1) When | P |> = 10 | D−D ₀ | <= 2: A = A ₀ × (1000 + n−1)
+ A '/ (1000 + n )> 2: No change (2) 10> | P | > = For _{5 | D-D 0 | <} = 1: A = A 0 × (1000 + n-1)
+ A ′ / (1000 + n)> 1: No change (3) In the case of P <5 | D−D ₀ | <= 0.5: A = A ₀ × (1000 + n−
1) + A ′ / (1000 + n)> 0.5: No change The A constant updated in this way is a value reflecting many A constants used in the past for the lens by all users who have used the service in the past. It can be said that this is the culmination of know-how on the lens. This A constant is used as the manufacturer's recommended value in the next lens power calculation. In other words, the present system is a know-how absorption type learning system that evolves into an A constant that is optimal for each of various types of intraocular lenses, that is, a selection criterion that is more reliable as the number of uses and the number of users increase. Doctors can also make sure that their know-how is certain. This increases the certainty of lens selection, reduces variations among individual doctors, and contributes to uniform selection.

The above is the flow of services as seen from the medical institution side. On the other hand, FIG. 3 is a flow showing the procedure of lens supply services as seen from the lens supplier company side.

In step 201 (providing online lens selection service), hospital A (1), hospital B (2), and medical laboratory
Provide the above-mentioned online services to medical institutions such as (3) through the Internet. The lens selection service system that provides the service is placed on a server or a rental server in an in-house LAN of a lens supplier. By allowing access from the service terminal of each medical institution via the Internet here,
Support selection of intraocular lenses to be used at each medical institution.
Alternatively, a service providing program or data may be installed in a local service providing server of the hospital LAN as in the medical institution B of FIG. Each time the hospital updates the electronic medical chart after the operation, the parameter (A constant) of the lens selection criterion is also updated, and the selection criterion becomes more reliable each time the number of service uses increases.

In step 202 (accept online order), an online order is received from a medical institution. The online ordering system that provides this service is built on a local server managed by the inventory management department of each hospital, but the online ordering system (45) that processes orders placed therefrom is provided by a lens supplier company's LAN. Server or rental server. The online order system (45) can access the in-house inventory management system (44) to obtain information on in-house inventory. The in-house inventory management system (44) centrally manages the inventory of all products handled by the lens supplier. The product serial codes (model name, serial number), date of manufacture, inventory location, Shipping date, shipping destination, date of use, place of use, type of use, other comments from medical institutions, etc.
It has a database in which various information is recorded. By accessing the database from the identification code of the product for which the order has been received, it is searched whether or not the stock that can be immediately shipped is in the company. After confirming that there is internal stock,
The online ordering system instructs the computer of the sales department or the distribution department to ship the order items to the hospital (step 204). Upon receiving the instructions, the sales or distribution department immediately delivers the order to the hospital.

By providing an online ordering service in cooperation with such a lens selection support service, a medical institution can order the selected lens on the spot, and accurate and prompt ordering is possible. If the intraocular lens is used for urgent treatment of a patient, it is necessary to receive the supply as soon as possible. Therefore, when ordering, the urgency of the supply can be indicated. In that case, as described below, if the manufacturer does not have stock at the hospital, stock from another medical institution is supplied.

In step 203 (inventory check), if there is no in-stock inventory of the ordered intraocular lens, a check is made to see if there is stock in the company. If the order is out of stock in the company and the order is urgent, the online ordering system checks the stock outside the company. This is not only the in-hospital inventory management system of the hospital that issued the order, but also the in-hospital inventory management system that each medical institution such as other hospitals and laboratories in the vicinity has independently access via the Internet, Check if the target product is available. To this end, the lens supplier receives in advance a limited access right to the in-hospital inventory management system that can at least search the stock status of its own supplies. The online ordering system sequentially searches a plurality of places to which the access right is given. Then, as a result of the search, the items are listed in the order in which they have surplus stock and are physically or temporally short from the medical institution. Along with the listed results, supply instructions are given to computers in the sales department or the distribution department (step 20).
4). In response, the sales department or distribution department dispatches a person in charge to the medical institution that can supply the product quickly, and delivers the necessary number of surplus stock to the hospital that placed the order. . Thereby, it is possible to cope with urgent medical processing.

In step 203, when the lens supply company accesses the in-hospital stock management server managed by the medical institution, the stock status of other types of intraocular lenses supplied in the past is also searched. As a result, a product whose stock is zero or insufficient is known. The online ordering system first checks the in-stock inventory of the missing product with the in-house inventory management system, and instructs the sales department or distribution department computer to voluntarily supply the lacking medical institution to the lacking medical institution. If there is no in-house inventory, the factory is instructed to manufacture the missing item. In this way, by establishing a system that partially opens the access to the inventory management server of the medical institution to the lens supplier and appropriately supplies the missing items, the medical institution can always obtain a necessary and sufficient inventory state.

In step 205 (instructing the factory to produce a lens), if there is no inventory in the company or if there is no inventory outside the company, an instruction is issued to the computer in the factory to produce the intraocular lens. The factory will promptly manufacture and ship the ordered products, helping to eliminate inventory shortages. In addition, for special patients who do not meet the standard products, custom orders can be ordered online, and the development department will design and manufacture them at the factory. Also in this case, the Internet and the network of the in-house LAN are used, and quick production and supply are performed. As shown in FIG. 10, each product package completed at the factory and before shipment is one by one.
Each time a bar code label showing a different product serial code is affixed. In order to manage the products shipped by this code, the computer of the factory accesses the in-house inventory management system via the in-house LAN, and adds and updates the new product serial code in the database.

As described above, part of the information recorded in the electronic medical record at the hospital, ie, part of the measurement data, the product serial code of the intraocular lens inserted into the patient's eye, date of use, and place of use Information such as the usage pattern is provided to the lens supplier via the Internet. Of these, information on inventory is recorded in the database of the in-house inventory management system of the lens supplier. Further, the information of the patient card is recorded in the same database. In other words, the introduction of this system allows the lens supplier to obtain information from the medical institution after shipment of its products and to perform tracking management. Since it is possible to know when, where and how each product after shipment is used in association with the product serial code, after-sales support of the product becomes easy.
The usage form of the product, that is, quality information and complaint information, as well as the patient's impressions and opinions are useful information for improving the product. These pieces of information are stored in a database of an in-house inventory management system, and can be accessed from a development department or a manufacturing department via an in-house LAN. Providing useful information within the company enables rapid product development and improvement. In addition, the manufacturing technique can be improved.
