Description

[Technical field]

[0001] The present invention relates to an infusion pump system, and more particularly to an infusion pump system capable of improving safety by checking the consistency of various pieces of information. [Background technology]

[0002] The infusion pump system includes an infusion container filled with infusion liquid, and an infusion pump device that injects the infusion liquid from the infusion container into a patient. The infusion pump device includes an infusion pump that delivers the infusion liquid at a predetermined infusion rate, and a drive control means that can control the amount and rate of infusion liquid injected by the infusion pump and stops the system when an abnormality occurs in the infusion pressure or rate of the infusion pump.

[0003] To operate the infusion pump system, the infusion tube is connected to the patient, and the infusion volume and infusion rate are set, and then the pump device is operated. The infusion volume and infusion rate are set by a doctor or nurse based on instructions prepared by the doctor. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2010-63763 A Summary of the Invention [Problem to be solved by the invention]

[0005] Since an infusion pump device injects medicine into a patient's body, incorrect settings of the type of infusion, the amount of infusion, the infusion rate, etc., can have a significant impact on the patient. Even if the settings are correct, if the infusion pump device malfunctions, it can lead to serious consequences just like incorrect settings. Even if the settings are correct and the infusion pump device does not malfunction, the patient's condition may change just before or during the infusion, making it necessary to change the infusion rate or amount of the infusion or to stop the infusion. For this reason, it is necessary to pay close attention to the management of the infusion pump device and the settings when using it, and to carefully observe the patient's condition before and during the infusion.

[0006] Usually, the type of infusion, injection amount, injection speed, etc. are set as a standard prescription by the pharmaceutical company that manufactures the infusion, and then the doctor sets the prescription for the type of infusion and the specific injection amount, etc., according to each patient, and treatment instructions are often created based on this. In large hospitals, the instructions are usually sent to a drug management department (e.g., a drug room), where an infusion container filled with the specified infusion is prepared and transported to the ward where the target patient is accommodated. The infusion pump device is managed in a material management department (e.g., an equipment room), and after inspection and maintenance, is transported to the ward based on the instructions, etc. Then, in the ward, the infusion container is attached to the infusion pump device, and the infusion is injected into the patient. The infusion container and the infusion pump device are usually operated by a nurse or the like based on the doctor's instructions. many.

[0007] In the above-mentioned system, the drug room where the infusion medicine is adjusted, the equipment room where the infusion pump is managed, and the department (ward) where the infusion is actually injected into the patient are often located separately. In addition, in each department, the person in charge of each department works. For example, the doctor who gives instructions for infusion adjustment, the nurse who injects the infusion into the patient, the pharmacist who prepares the infusion, and the engineer who manages the infusion pump device work in different places. For this reason, if information regarding the type of infusion, injection amount, injection speed, etc. for a specific patient is not accurately transmitted, a serious accident may occur. In addition, although the inspection and maintenance of the infusion pump is performed in the equipment room, it is necessary to check in the ward before injecting the infusion whether the inspection and maintenance are performed properly and whether it works normally. For this reason, in each department, the information is repeatedly confirmed based on the above-mentioned instructions and inspection and maintenance records, etc., to prevent accidents such as mix-ups and setting errors from occurring.

[0008] The above confirmation work is repeated in each department, but there is a possibility that the instructions will be misread. In addition, the contents that can be written on the instructions and the items and contents that each department can check are limited. For example, the instructions do not include information on the patient's past drug administration history, and in order for a ward nurse to check whether the instructions written on the instructions are correct, he or she must refer to previous drug administration records. In addition, whether the infusion pump works properly is a matter managed by the material department, and is not included in the instructions. In the ward, it is necessary to check the information on the infusion for a specific patient and confirm that the infusion pump works properly before injecting the infusion.

[0009] The infusion information is often confirmed by comparing the information written on the instruction sheet, the information written on the infusion container, and patient information such as the patient's name. Furthermore, the infusion pump device must be set up based on each of the above pieces of information. For this reason, it is impossible to completely eliminate the possibility of confirmation errors or setting errors in the infusion pump device.

[0010] The objective of the present invention is to provide an infusion pump system that can efficiently transmit, exchange, and confirm information about infusions and the patients to which they are applied in various organizations inside and outside hospitals that handle infusion containers and infusion pump devices, while improving the accuracy of confirmation work associated with treatment using infusions and preventing errors and problems from occurring in infusion treatment using these devices. [Means for solving the problem]

[0011] The present invention relates to an infusion pump system including an infusion pump device that can be fitted with an infusion container filled with infusion liquid and that injects the infusion liquid from the infusion container into a patient. The infusion container is configured with an IC tag in which predetermined information is written. The infusion pump device is configured to include an IC tag reading means for reading out information stored in the IC tag, a pump means for discharging the infusion liquid from the infusion container, a pump driving means for driving the pump means, a drive control means for controlling the pump driving means to discharge the infusion liquid at a predetermined flow rate, a container information detection means for collecting container information from the fitted infusion container, an input means for inputting patient information and infusion information, a display means for displaying predetermined information, a control signal generation means for generating control signals for controlling the drive control means, the container information detection means, the input means and the display means, an execution information output means for outputting execution information executed by the control signal generation means and the drive control means, an abnormality information detection means for detecting an abnormality in the system and outputting it to the drive control means or the control signal generation means to control the operation of the pump driving means, and a storage means for storing predetermined information. In addition, predetermined information is written in the storage means separately from the IC tag. The control signal generating means receives the information stored in the IC tag, the information inputted from the input means, Information written in the storage means separately from the IC tag and the above container information Including information written in the storage means separately from the IC tag The device is configured to generate a predetermined control signal based on two or more pieces of information, and the drive control means, the input means, the display means, and the abnormality information detection means are operated based on the control signal.

[0012] The type of infusion container is not particularly limited, and may be, for example, a bag-shaped container or a syringe-shaped container.

[0013] An IC tag is provided on the infusion container. The IC tag is a type of storage device that can electromagnetically record and read information. There are no particular limitations on the type of IC tag, but it is sufficient that the IC tag can at least be one that allows patient information and the like to be written by a server or the like installed in the infusion management department of the hospital.

[0014] There is no particular limit to the place where or the person who attaches the IC tag to the infusion container. For example, the IC tag may be attached in the purchasing department of the hospital, or a pharmaceutical manufacturer may attach an IC tag with standard infusion information written therein and deliver it to the hospital. Furthermore, there is no particular limit to the department in the hospital that installs a device for writing information to the IC tag. A writing device may be installed in the pharmaceutical room, and the pharmaceutical manufacturer may write specific infusion information and attach it to the IC tag attached to the infusion container, and then additional information such as patient information and infusion rate created by a doctor or the like may be written.

[0015] In addition, in a hospital, various information can be written to the IC tag attached to the infusion container in the medicine room where the infusion is adjusted, the equipment room where the infusion pump device is managed, and the ward where the infusion is injected into the patient. If the infusion container with the IC tag does not pass through the equipment room where the infusion pump device is managed, predetermined information such as operation information can be input to the memory means of the infusion pump device in the equipment room, and when the infusion container is attached to the infusion pump device, the information stored in the memory means of the infusion pump device and the IC tag can be integrated and used as integrated information.

[0016] The location of the infusion container where the IC tag is provided is not particularly limited, but it may be provided at a location where the IC tag can be read and written by an IC tag reader provided on the infusion pump device when the infusion container is attached to the infusion pump device. The infusion container may be configured so that the information stored in the IC tag can be read without being attached to the infusion pump device. For example, a general-purpose IC tag reader that can be connected to the infusion pump device by a cord or the like may be separately prepared, and the IC tag provided on the infusion container or the like may be held up to read the information. This allows for cases where a drug is added to the infusion container before the infusion container is attached to the infusion pump device in a hospital ward.

[0017] The amount of information that can be stored in the IC tag is much larger than the amount of information written on paper media such as instructions, and complex information can also be stored. Therefore, information that has not been written on instructions can be stored. The type of information stored in the IC tag is not particularly limited. Information necessary for infusion injection, such as information on infusion rate, information on injection amount, and patient information, can be written. In addition, when an IC tag writing means is provided in the infusion pump device, not only the above information but also execution information that has not been written on conventional instructions, such as execution information during infusion injection and confirmation information after the end of infusion injection, can be written. In addition, the IC tag can be configured to store control information for the infusion pump device and to perform a specified operation in the infusion pump device, or to write operation confirmation information for the infusion pump device before infusion injection and abnormality information for the device.

[0018] The infusion pump device includes an IC tag reading means for reading information stored in the IC tag. The IC tag reading means is configured to include a stage. The configuration of the IC tag reading means is not particularly limited. Since the IC tag electronically reads information without contact, by installing a reading means at the site where the infusion container is attached or in its vicinity, the information stored in the IC tag can be reliably read and sent to the memory means and drive control means of the infusion pump device. In addition, since the information can be read without contact, it can be built into the device.

[0019] The configuration of the pump means is not particularly limited. A roller type pump means using a tube, a peristaltic type pump means, a syringe type pump means, etc. can be used. The configuration of the pump drive means can also be set according to the type of the pump means.

[0020] The configuration of the pump drive means is not particularly limited. For example, the pump drive means can be configured using various types of electric motors. Also, various actuators using air pressure or hydraulic pressure can be used as the pump drive means.

[0021] The pump driving means is controlled by the drive control means. The drive control means not only starts and stops the pump driving means, but also drives the pump driving means so that the infusion is infused at a predetermined flow rate. The drive control means can also be configured to perform a test run of the infusion pump device based on a predetermined signal, or to stop the pump driving means based on abnormality information. Information on the actual drive control by the drive control means is output as execution information and written to a storage means or the like.

[0022] When an electric motor is used as the pump driving means, a known motor control device can be used as the drive control means. The drive control method is not particularly limited, and feedback control or a servo mechanism can be used. Also, when a pneumatic or hydraulic actuator is used, a known control device can be used.

[0023] The container information detection means detects container information from the attached infusion container. The size and shape of the infusion container are determined by the injection amount and the type of drug filled. For example, a drug with a large injection amount is contained in a large infusion container, while a drug with a small injection amount is contained in a small infusion container. Therefore, by detecting the size, shape, etc. of the infusion container with a sensor, part of the information regarding the infusion can be obtained. By comparing the information obtained from these containers with the information written on the IC tag or the information input by the input means and checking the consistency, it is possible to verify whether there is an error in the type of drug adopted and the injection amount. This can improve safety.

[0024] The configuration of the container information detection means is not particularly limited. For example, in the case of an infusion container having a syringe shape, a sensor or the like that detects values ​​such as the thickness and length of the attached syringe can be adopted. Also, information regarding the injection amount can be detected by detecting the weight of the infusion container. Furthermore, in the case of a syringe-shaped container, the pressing force and position of the plunger can be measured and used as container information and drug amount information. The container information is not limited to information regarding the shape and dimensions of the infusion container, and can be configured to collect container information from, for example, a pattern or color applied to the surface.

[0025] The input means is configured to allow at least patient information and infusion information to be input in the ward. For example, the infusion rate of infusion can be input based on a doctor's instructions. In the present invention, since infusion information and patient information are stored in the IC tag, a nurse or the like inputs patient information and infusion information in the ward, and the consistency between the information written on the IC tag and the information input in the ward can be automatically verified. The configuration of the input means is not particularly limited. For example, a touch panel device such as a liquid crystal panel formed integrally with the display means can be adopted. In addition, the input information is not particularly limited, and the infusion pump device can be configured to display confirmation items before operation, and to generate a confirmation signal by pressing a confirmation button or the like after confirmation. Then, it is desirable to output this confirmation signal to the control signal generating means, and to generate a control signal after this signal to start the infusion. Furthermore, there may be cases where the test results are obtained immediately before the infusion treatment, making it necessary to change the type of drug or the infusion conditions, or where the patient's condition suddenly changes. In such cases, the input means is also used when it is necessary to change the information written in the IC tag. Also, when change information has already been written, it is possible to configure so that input is made to confirm the contents of the change.

[0026] Conventionally, confirmation work is performed mainly on predetermined items such as the type of infusion, the infusion rate, and the amount of infusion based on the instruction sheet, but the items to be confirmed may differ depending on the type of infusion, the patient's condition, and the medical institution. In such a case, the confirmation work is made easier by displaying the information that needs to be confirmed preferentially and configuring the infusion pump device to start based on the presence or absence of confirmation of this information. In addition, safety is improved. For this reason, a mandatory display item designation means is provided that adds mandatory display item information among the written information, and the display means of the infusion pump device is configured to display the mandatory infusion information preferentially based on the mandatory display item information. On the other hand, a display information selection means may be provided that stores general prescriptions for drugs in an IC tag and selectively displays the infusion information when a question arises about the prescription of drugs in the ward.

[0027] In the present invention, an execution information output means is provided that can output execution information of the infusion pump device executed by the control signal generating means and the drive control means. The execution information is information on the treatment actually performed on a specific patient, and is also operation information of the system and the infusion pump device. In particular, in the infusion injection operation, the type of infusion, the injection amount, etc. are often changed immediately before depending on the patient's condition, etc. In such cases, the change instruction is often given by an instruction sheet, etc., but the medicine is often already transported to the ward, and it is often difficult to write information on the IC tag in the medicine room, etc. In addition, depending on the patient's condition, etc., the injection may be terminated midway. For this reason, it is necessary to verify after the fact whether the infusion injection was performed according to the specified instructions. By accumulating the above information, information on a specific patient and the operation history of the infusion pump device are accumulated, and by analyzing this, the above verification can be easily performed. In addition, even if a mistake or the like occurs, it is possible to verify whether there is no problem immediately after the infusion injection, and it is possible to respond quickly.

[0028] In addition, since information can be collected during the execution process, abnormal operation of the device can be detected and the device life can be predicted by collecting and analyzing operation information of the device and system. The execution information is stored in the storage means and the IC tag. As the information, for example, not only infusion injection information such as the injection amount (discharge amount) of the infusion liquid, the injection speed, and the injection pressure, but also the operation time of the pump device and the resistance change of the driving means can be recorded. Not only can this information be used for setting operations during subsequent injections, but it can also be configured to detect abnormalities in the device by comparing information output in real time with past information recorded in the IC tag, etc.

[0029] As the output destination of the execution information, not only the IC tag but also the storage means of the infusion pump device can be used. Since the IC tag is attached to the infusion container, it may not pass through the equipment room that manages the infusion pump device after use. Therefore, by recording the operation record of the device as execution information in the storage means, management materials for the infusion pump device can be created and used for maintenance, etc. Also, a system can be constructed that allows the information extracted from the IC tag of the infusion container to be shared with other departments.

[0030] The abnormality information detection means detects an abnormality in the system and controls the drive control means and the control signal generation means. The abnormality information detection means outputs the abnormality information to the infusion pump device and controls the operation of the pump drive means. The information detected as the abnormality of the system is not particularly limited. For example, the abnormality information detection means can be configured to detect an abnormality of the infusion pump device, an abnormality of the power supply, etc. Also, the system can be configured to detect the injection pressure, the displacement of the infusion container (abnormality in the mounting state, etc.), etc. Also, the abnormality information detection means can be configured to directly control the drive control means, or the control signal generation means can be configured to generate a predetermined control signal based on the output information. Furthermore, the system can be configured to detect not only abnormalities while the infusion pump device is operating, but also abnormalities while the infusion pump device is not operating. For example, when the infusion pump device is subjected to an impact during storage or transportation, an abnormality signal can be generated and stored in the storage means, and when the infusion pump device is operated, the occurrence of an abnormality can be displayed on the display means.

[0031] The control signal generating means is configured to generate a signal for driving the pump driving means, and also to analyze various information to determine whether the infusion pump device is operable or not. The control signal generating means is also configured to generate various control signals related to the display contents of information stored in an IC tag, etc., and control signals for recording execution information performed in the infusion pump device.

[0032] The storage means may be any of various storage devices that can write and read information. For example, a known flash memory may be used. In addition, the storage means is not limited to a fixed storage device, and may be a removable storage device such as an SD card. In addition, an IC tag other than the one attached to the infusion container may be used as the storage means.

[0033] The information stored in the storage means is not particularly limited, and not only information necessary for driving the infusion pump device, maintenance information for the infusion pump device, but also historical information of the target patient, etc. can be stored in advance. Also, information stored in an IC tag attached to an infusion container can be imported into the storage means in the infusion pump device and integrated with the information stored in the IC tag to perform various controls. Conversely, the storage means of the infusion pump device can be configured to store information necessary for driving the infusion pump device, maintenance information for the infusion pump device, and other information. Written The information can be integrated by importing it into an IC tag attached to the infusion container. In addition, infusion preparation is often completed the day before. Meanwhile, the condition of the patient changes from moment to moment. In particular, there are many cases where the condition changes or the test results become clear on the morning of the treatment. In such cases, it is possible for the doctor to give instructions directly to the ward verbally or in writing, but this increases the risk of mistakes. For this reason, when making changes to the medicine or infusion rate instructed by the doctor, it is preferable to transmit the information from the doctor's terminal to the drug room and equipment room and update the instructions. However, since the preparation of the infusion container and the preparation of the infusion pump device are performed in different departments, there may be a time lag in the transportation to the ward. In the present invention, information is written to the storage means separately from the information written to the IC tag. There are cases where the information written on the tag of the infusion container does not match the information stored in the memory means of the infusion pump device. That is,When there is a difference between the information written in the IC tag of the infusion container and the information written in the storage means of the infusion pump device, it is preferable to judge whether or not there has been updated information, and when there has been an update to the infusion information, to display that fact on the display means of the infusion pump device, and to operate the device after confirming the updated contents. Furthermore, when there is no consistency between the IC tag of the infusion container and the information written in the storage means of the infusion pump device, safety is also enhanced by controlling the infusion pump device not to operate until confirmation and correction are performed.

[0034] The control signal generating means generates a control signal based on information stored in the IC tag attached to the infusion container and information stored in a storage means of the infusion pump device. Written The control signal generating means can generate a predetermined control signal based on the information input from the container information and the information input from the input means of the infusion pump device. It is structured as follows:

[0035] Based on the control signal, the drive control means, the input means, the display means, and the abnormality information detection means are operated. The type of the control signal is not particularly limited. For example, a control signal for controlling the speed of the drive means can be generated to control the infusion speed of the infusion. Also, a signal for controlling the operation of the display means and the input means can be generated. For example, when an abnormal signal is detected or when there is an inconsistency in each piece of information, the display means can be configured to display the inconsistency. Furthermore, when there is no consistency in the signals from each means, the operation can be stopped and a warning can be displayed on the display means. In particular, when change information is input to the storage means of the infusion pump device in the equipment room after the infusion container is transported to the ward, or when change information is directly input from the input means of the infusion pump device in the ward, it is preferable to configure so that it is possible to verify whether there is a problem with the change information. For example, it is preferable to configure so that the standard application conditions of the drug can be stored in the IC tag or the storage means and compared with the input contents.

[0036] The infusion pump device can be provided with an IC tag writing means for writing predetermined information to the IC tag. In particular, when the patient's condition changes immediately before infusion, the drug to be injected and the amount are often changed. Changes are made based on instructions, but by writing the changed content to the memory means of the infusion pump device, confirmation work can be performed reliably. In addition, execution information can be reliably recorded. The IC tag writing means can be configured not only to write information via the input screen (display screen) of the infusion device, but also to automatically store information output from each means of the infusion pump device. For example, it can be configured so that numerical information input from the input means is automatically written to the IC tag. In the memory means of the infusion pump device, Written The IC tag writing means can be configured to automatically transfer information to the IC tag. The IC tag writing means can also be controlled by control information generated by the control signal generating means.

[0037] In the hospital ward, various information can be written to the IC tag via the IC tag writing means. Not only the patient's name but also patient information such as body temperature information, which has been recorded on paper up to now, can be written. Also, confirmation items can be displayed on the display means, and check information to the effect that the confirmation has been made can be written. Also, the system can be configured to write the execution information and abnormality information to the IC tag or storage means during or after the system operation has ended.

[0038] The control signal generating means receives information stored in the IC tag, The IC tag is written to the storage means separately. A determination means may be provided that can compare two or more pieces of information among the information, the information inputted from the input means, and the container information to determine whether or not there is a predetermined consistency. It is preferable that the information to be compared includes information written in the storage means separately from the IC tag.The discrimination means may be configured with a microcomputer and may be configured with a required program and information data stored in the storage means. The combination of information used for the discrimination is not particularly limited, and may be set according to patient information, the type of infusion, etc. The type of control information generated according to the result of the discrimination means is also not particularly limited. For example, when there is an inconsistency in the information, the device may be configured to generate a stop command information for the device, and generate display information related thereto, etc., and display it on the display means, etc. When an injection amount or injection rate that deviates from the standard prescription is input, a confirmation screen may be displayed to confirm whether or not it is appropriate.

[0039] In addition, it is also possible to configure the system so that, when a significant change has been made by comparing the past injection history of the patient, a confirmation screen is displayed to request confirmation. By providing the above-mentioned discrimination means, the confirmation process becomes easier and safety can be significantly improved.

[0040] It is necessary to write instructions such as injection amount and injection speed in the IC tag based on the doctor's instructions. For this reason, a system can be configured that writes predetermined information in the IC tag and includes a server device that can output and record the information written in the IC tag. As described above, the system can be configured so that the IC tag is attached by the drug manufacturer and standard prescriptions and the like are written, and the hospital can add information for a specific patient such as injection amount and injection speed.

[0041] The department in which the server device is installed is not particularly limited. It can be installed in a medicine room, an equipment room, or even in a department that purchases infusion containers. Each department can be configured to input predetermined information into the IC tag or memory means.

[0042] The server device includes an IC tag writing means for writing predetermined information to the IC tag, an IC tag reading means for reading the information written in the IC tag, and an information analysis means (artificial intelligence) for analyzing the information read by the IC tag reading means to generate predetermined information.

[0043] The information analysis means may be provided with a discrimination means capable of discriminating a predetermined consistency between the information written in the IC tag and the information to be written. For example, when the doctor's instructions regarding the infusion rate or amount differ from the standard prescription such as the infusion administration method specified by the pharmaceutical manufacturer, there may be a problem with the instructions. In such a case, the safety can be improved by detecting the inconsistency when writing the infusion information in the IC tag. The discriminating information for the inconsistency may be configured to discriminate not only between two or more pieces of information to be written in the IC tag, but also between information already written in the IC tag and information to be written, and between pieces of information already written in the IC tag.

[0044] The control method for the infusion pump device according to the present invention is executed based on information written in an IC tag provided on an infusion container attached to the infusion injector, information written in a storage means provided in the infusion injector, information input during infusion, etc. An IC tag information input step of writing predetermined information into the IC tag; In addition to the IC tag information input process A storage means information input step of writing predetermined information into the storage means, and an infusion pump device input step of inputting predetermined information into the infusion pump device ,eachSince the processes are performed in separate departments, not only is there a time lag, but input errors are also likely to occur. The present invention includes an input information comparison step for comparing the information input in each of the above steps, and can be configured to output predetermined information and stop control of the infusion pump device if an inconsistency is detected in the information input in the input information comparison step. This significantly increases the safety of infusion injection therapy. Furthermore, safety can be further increased by configuring the department where the server is installed to check the consistency with information in other departments.

[0045] When maintenance work is performed on the pump device, it is preferable that predetermined maintenance work completion information is written to the storage device and the maintenance work completion information is displayed on the display means at a predetermined timing. For example, it is preferable that when the infusion pump device is started, a display is displayed indicating that the maintenance work has been successfully completed, and after an input is made to confirm this, the drive means is driven. Furthermore, it is preferable that the control signal is not generated if there is an abnormality in the maintenance work completion information. This makes it possible to check the state of the infusion pump device before injecting an infusion into a patient, thereby improving safety.

[0046] The server device can write various information to the IC tag, which can be displayed on the display means of the infusion pump device. Various display information can be written to the IC tag. , it is not necessary to display all of the information. For this reason, it is desirable to configure the system so that information relating to the mandatory confirmation items that need to be confirmed is automatically displayed from among the written information. In order to specify information relating to the mandatory items, a mandatory display item specification means is provided which adds mandatory display item information. The mandatory display item specification means is configured so that information that must be confirmed depending on the type of infusion and the patient can be specified. The display means of the infusion pump device displays the mandatory infusion information based on the mandatory display item information. Meanwhile, a display information selection means can be provided which can selectively display infusion information other than the mandatory items. This makes it possible to quickly and easily resolve any questions that arise in the ward.

[0047] The server device is preferably configured to store the information read from the IC tag and generate statistical information for patients to whom the infusion has been administered. The statistical information can be used not only for treatment but also as background information for the next infusion. For example, the server device can be configured to use the information analysis means to compare the information written in each IC tag with the statistical information to determine consistency.

[0048] On the other hand, there are cases where it is desired to collect broad information about infusions, etc. However, the information recorded in the IC tag is personal information and cannot be used for purposes other than the treatment of the patient. For this reason, the information analysis means can be configured to anonymize the information read from the IC tag and generate statistical information. This makes it possible to obtain general statistical information when using infusions. In addition, since the information can be anonymized when reading from the IC tag of the infusion container after use, it is also possible to reduce the risk of personal information leaking. Furthermore, by combining the patient's case, treatment effect, etc., it can be used as statistical information at each medical institution.

[0049] The information analysis means can be configured to accumulate the information read from the storage means and generate statistical information regarding the infusion pump device. For example, it is possible to collect and manage information regarding the operation time, etc. This makes it possible to utilize the information for maintenance of the pump device. The information analysis means can also be configured to generate required maintenance information from the statistical information of the infusion pump device. Effect of the Invention

[0050] This can improve the safety of not only the infusion pump device but also the entire infusion pump system. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0052] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The infusion pump system according to this embodiment does not only relate to infusion as a therapeutic drug or an infusion pump device as a device, but also includes a processing device and a method for various information related to the infusion and the device, and information on treatment performed using the infusion and the device, in organizations inside and outside a hospital that handle these. In this embodiment, a syringe container is used as the infusion container, and a syringe pump that can press the plunger of the syringe at a predetermined speed is used as the infusion pump device.

[0053] 1, an infusion pump system 1 includes a syringe container 2 serving as an infusion container filled with an infusion liquid, and a syringe pump 3 serving as an infusion pump device to which the syringe container 2 is attached and which pushes a plunger 10 of the syringe container 2 to inject the infusion liquid from the syringe container 2 into a patient. The system also includes servers 6, 7, etc. that handle information relating to the syringe container 2 and the syringe pump 3 in a medicine room 4 and an equipment room 5 that handle the syringe container 2 and the syringe pump 3.

[0054] 2, the syringe container 2 is configured with a cylindrical outer tube 8 filled with infusion liquid, an oval flange portion 9 formed by extending radially outward at the base end of the outer tube 8, and a plunger 10 inserted into the outer tube from the base end, and the syringe container 2 itself constitutes a pump means. The syringe container 2 is entirely formed by resin molding, and a discharge port 11 to which an infusion tube is connected is formed at the tip end of the outer tube. In addition, a gasket 12 is provided at the tip end of the plunger 10 to seal the gap with the inner surface of the outer tube, and a plunger flange portion 13 is provided at the base end of the plunger.

[0055] In this embodiment, an IC tag (REID) 14 is attached to the outer surface of the outer cylinder as shown in Fig. 2. The IC tag 14 is a kind of luggage tag with a built-in IC chip capable of wireless communication. Various electronic information is written in the IC tag 14, and information can be written and read by short-range wireless communication using an electromagnetic field, radio waves, etc.

[0056] For example, as shown in FIG. 9, the IC tag 14 can be written with infusion information, patient information, injection information, history information, caution information, and the like. The infusion information can include the name of the infusion, standard use information of the infusion, and the like. The patient information can include information necessary for applying the infusion, such as the patient's name, age, weight, and disease name. The infusion information can include the injection amount and injection rate written in the instruction sheet prepared by the doctor. The history information can include the type of infusion, injection amount, injection rate, injection date and time, and the like of past injections. The caution information can include the patient's condition when the infusion is injected. For example, when the body temperature or blood pressure is beyond a predetermined range, information such as instruction information not to inject the infusion can be included.

[0057] For infusions filled in syringe container 2 and delivered to a hospital, drug manufacturer 15 attaches IC tag 14 to syringe container 2, and inputs information such as the name of the infusion and general prescription into IC tag 14. After syringe container 2 is delivered to a hospital, applicable patient information, etc. can be added to IC tag 14.

[0058] As shown in Figures 3 and 4, the syringe pump 3 is provided with a syringe barrel holding means 16 for holding the barrel 8 of the syringe container 2, and a pushing means 17 for holding and pushing the plunger flange portion 13 to eject the infusion liquid.

[0059] The syringe outer cylinder holding means 16 is formed between an outer cylinder holding portion 16a, which is configured by providing a mounting surface having a substantially cylindrical inner surface shape on the upper surface of the housing of the syringe pump 3, on which the outer surface of the outer cylinder 8 can be mounted, and a pair of vertical walls 16b, 16c provided on the base end side of the outer cylinder holding portion 16a, and the flange 16b is formed between the outer cylinder holding portion 16a and the flange 16c. The syringe barrel 8 is configured to include a flange holding portion 16d into which the syringe barrel 9 can be inserted and locked, and a clamping lock mechanism 18 that can clamp the syringe barrel 8 between the flange holding portion 16d and the mounting surface.

[0060] The pushing means 17 constitutes a pump driving means, and includes a slider 19 configured to hold the flange portion 13 of the plunger 10 and to be movable in the axial direction. The slider 19 is pushed in the axial direction by rotating a drive screw (not shown) by a motor serving as a driving means, and causes the infusion solution contained in the outer cylinder 8 to be discharged from the discharge port 11.

[0061] The clamping lock mechanism 18 includes an arm portion 18a that clamps and holds the syringe outer cylinder 8 between itself and the mounting surface. The arm portion 18a is configured to be able to elastically clamp the syringe outer cylinder 8. In this embodiment, the clamping lock mechanism 18 constitutes a container information detection means 20 that can detect the size (outer diameter) of the syringe by detecting the rotation angle of the arm portion 18a.

[0062] The container information detection means 20 is configured to include a variable resistor (not shown) whose resistance changes in response to the rotation angle of the arm portion 18a, and is configured to be able to identify the type, volume, etc. of the syringe container 2 from an infusion-volume table (not shown) based on the output from the variable resistor. The infusion-volume table is stored in a storage means 21 provided in the syringe pump or the IC tag 14, and is configured to be able to measure the outer diameter of the syringe outer cylinder by the detection resistance of the variable resistor, and to read out the volume, etc. of the syringe corresponding to this outer diameter from the infusion-volume table. In addition, in this embodiment, the position of the plunger 10 is configured to be able to be detected from the position of the slider 19. The amount of infusion filled in the syringe container 2 can be detected by these pieces of information. Also, the infusion-volume table is configured to be able to detect the infusion that may be filled in the syringe of the volume detected by the syringe detection means. In addition, by comparing the contents read from the infusion-volume table based on the data detected by the container information detection means 20 with the infusion information written in the IC tag, it is possible to determine the consistency between the syringe container and the infusion, thereby preventing mix-ups of medications.

[0063] As shown in FIG. 5, the syringe pump 3 is provided with various means. The storage means 21 is composed of a semiconductor memory or the like provided in the syringe pump, and can store the various information described above. The storage means 21 also stores operational test information of the infusion pump performed in the equipment room, and can display the information on the display means 22 provided on the top surface of the syringe pump as necessary. Furthermore, in order to write information to the IC tag of the syringe container 2 filled with the infusion liquid, it is necessary to use the server 6 in the medicine room, and it is necessary to complete the preparation of the syringe container the day before the drug injection. On the other hand, the storage means 21 of the syringe pump 3 can write information directly from the input means of the syringe pump body, in addition to the server 7 in the equipment room. Also, the syringe pump is often prepared on the day. For this reason, it is often possible to add change information or additional information to the storage means 21 before the syringe pump is transported to the ward. For this reason, if any change occurs in the information on the day of drug injection, it is preferable to communicate this information not only to the medicine room but also to the equipment room, and to write the information not only to the IC tag of the syringe container 2 but also to the above-mentioned memory means 21.

[0064] The syringe pump 3 is also provided with an abnormality information detection means 32 that outputs abnormality information when, for example, an impact is applied during transport. The abnormality information detection means 32 can be configured using various acceleration sensors, etc. When an impact is applied, an abnormality signal is output from the abnormality information detection means 32 even when the power supply to the syringe pump 3 is turned off, and the abnormality information is stored in the storage means 21, etc.

[0065] A pressing force detection means (not shown) capable of measuring the pressing force of the plunger 10 is provided at an appropriate portion of the drive mechanism (not shown) for driving the slider 19. The pressing force detection means constitutes a part of the container information detection means 20, and can be configured, for example, by including an elastic piece (not shown) that is elastically deformed by the pressing force from the plunger, and a resistance strain gauge attached to the elastic piece. The pressing force of the plunger can be detected using the output from the resistance strain gauge, and the injection pressure at the discharge port can be indirectly detected. The pressing force when the infusion is not being injected into the patient can be estimated to be a value corresponding to the sliding resistance between the outer cylinder of the syringe container and the gasket, i.e., the outer diameter of the syringe container, and therefore, by combining it with information from the syringe detection means, it can also be used as information for determining whether the syringe container as a pump means is operating normally.

[0066] On the upper surface of the syringe pump 3, an operation panel 24 is provided, which includes a display means 22 for displaying various information and values ​​to be set, and various operation switches 23 as input means. As shown in FIG. 4, the display means 22 is composed of a liquid crystal display device, and also constitutes a touch panel as input means. For example, as shown in FIG. 7, a confirmation screen showing predetermined confirmation information is displayed, and a response signal (confirmation signal) to the displayed confirmation information can be generated by touching the "OK" display of confirmation buttons 23a, 23b, and 23c on the screen. In particular, when there is change information such as the type of drug or the injection rate, it is preferable to display this information to call attention to the fact that the settings have been changed and to confirm it. Also, as shown in FIG. 8, a value increase switch 25 and a value decrease switch 26 for setting the values ​​displayed on the display means 22 are provided on the side of the display means 22. The switches 25 and 26 are composed of film switches. Although not described, other switches such as a power switch are also provided on the upper surface of the syringe pump 3.

[0067] As shown in Fig. 5, the syringe pump 3 is provided with an IC tag reading means 27 and an IC tag writing means 28. As shown in Fig. 3, the IC tag reading means 27 and the IC tag writing means 28 are provided adjacent to the syringe barrel holding means 16 and facing the IC tag 14 affixed to the syringe container 2 with a predetermined gap therebetween. The configurations of the IC tag reading means 27 and the IC tag writing means 28 are not particularly limited, and any known IC tag reading and writing means can be used.

[0068] A drive control means 29 is provided to control the motor constituting the pushing means 17 (pump drive means). In this embodiment, the speed of the motor driving the slider 19 can be controlled, and the motor is configured to stop operation in response to a predetermined abnormality signal. The motor can be configured to measure the power for driving the motor and generate an abnormality signal when the power exceeds a predetermined range. The motor can also be configured to detect the number of rotations to detect the movement information of the slider, i.e., the injection speed of the infusion liquid. The drive control means 29 can be configured using various integrated circuits.

[0069] Further, in this embodiment, there is provided a control signal generating means 30 that generates control signals for controlling the drive control means 29, the container information detecting means 20, the operation switch 23 and the display means 22. The control signal generating means 30 processes the various information described above and generates control signals that instruct the operation of each of the above means.

[0070] The present invention is configured to be able to generate a predetermined control signal based on information written on an IC tag provided on an infusion container attached to the infusion pump device, information written separately from the IC tag in a memory means provided in the infusion pump device, information input from an input means of the infusion pump device during infusion injection, and container information obtained by a container information detection means provided in the pump device. In this embodiment,As shown in Figure 9, the control signal generating means 30 is equipped with a discrimination means 31 that can compare two or more pieces of information among the information stored in the IC tag 14, the information stored in the memory means 21, the information input from the input means 23, and the container information obtained from the container information detection means 20, and determine whether there is a predetermined consistency, and outputs a predetermined control signal to each means based on the discrimination result of the discrimination means 31.

[0071] Confirmation information and numerical information from the IC tag 14, the storage means 21, the container information detection means 20, and the input means 23 including the display touch panel are input to the control signal generation means 30. The discrimination means 31 of the control signal generation means 30 checks whether or not conflicting or inconsistent information is included in this information, that is, whether or not each piece of information is consistent. After the consistency is confirmed, a control signal is output to the drive control means 29, etc., based on the information input from the IC tag and the input means.

[0072] An outline of the operation of the infusion pump system 1 according to this embodiment will now be described with reference to the flowcharts of FIGS.

[0073] First, a doctor creates an infusion instruction sheet (S101), and the instruction sheet is submitted to and accepted by the pharmacy (S102). The instruction sheet is often created or input by the doctor's terminal 202 based on the test information 201, etc., and the staff of the pharmacy adjusts the medicine based on the instruction sheet (S103). Usually, the infusion is manufactured by a pharmaceutical manufacturer and filled into a syringe container (S104). Then, an IC tag 14 with a standard prescription or the like written therein is attached to the syringe container 2 (S105), which is shipped to the hospital and delivered to the pharmacy. The staff of the pharmacy often selects a syringe container filled with the medicine written in the instruction sheet to adjust the infusion. In addition, in the pharmacy, it is also possible to adjust the infusion by mixing a plurality of infusions. In this case, the IC tag 14 is attached to the syringe container 2 in the pharmacy, and information such as the name of the medicine is written therein. In addition, it is also possible to additionally fill an infusion container filled with a specific medicine with another medicine, and to add information on the additionally filled medicine to the IC tag. It is also possible to embed an IC tag with no information written thereon in a predetermined position of the syringe container 2 during the manufacturing stage of the syringe container 2, and then have the information added thereto in each of the above-mentioned departments.

[0074] In the medicine room, information about the infusion and the patient is written to the IC tag based on the instruction sheet (S106). As shown in Fig. 13, in this embodiment, information such as the name of the infusion medicine, ingredients, and general prescription is written to the IC tag by the medicine manufacturer 15. For example, the injection amount (prescribeable injection amount range), injection rate (prescribeable injection rate range), and other general precautions are written to the IC tag by the medicine manufacturer, and the IC tag is attached to the syringe container 2 filled with the infusion, and then shipped to each hospital.

[0075] In the pharmacy room 4, the application information for a specific patient is added to the IC tag 14 based on the doctor's instructions (S106). In the pharmacy room, as shown in FIG. 1, a server 6 capable of writing and reading information to the IC tag is installed. Using the server 6, for example, the patient's name, sex, age, injection amount, injection speed, and other notes are added to the IC tag 14 attached to the syringe container 2. At this time, if there is no consistency between the information input in the pharmacy room and the information input by the drug manufacturer (NO in S107), for example, if the drug name written in the pharmacy room based on the doctor's instructions is different from the drug name of the selected syringe container, or if the injection amount, injection speed, etc. are outside the range of the injection amount or injection speed written in the IC tag by the drug manufacturer, the server can be configured to issue a warning (S108). When a warning is issued, the staff of the pharmacy room can check with the doctor who prepared the instructions and require him to correct the input contents if necessary (S109).

[0076] In other words, the system requires users to input information that should be the same (including ranges, etc.) in different departments, and issues a warning if the input information is inconsistent. This method makes it possible to detect drug types and drug injection amounts that exceed the applicable range set by the drug manufacturer in advance. This makes it possible to prevent mistakes in the instructions on the instruction sheet and mixing up medicines. If the settings are made beyond the range of application set by the medicine manufacturer, the warning can be cancelled by performing a specified operation.

[0077] Meanwhile, as shown in FIGS. 1 and 10, the syringe pump 3 is first transported to the equipment room 5 where consumables are replaced and various adjustments are made (S201), and an operation check is performed to determine whether the syringe pump 3 is operating normally (S202). The check results and the check date are then written to storage means (memory) 21 provided within the syringe pump (S203).

[0078] The check information may also include operation information when a specific syringe container is attached. For example, detection information and pressing force information for the specific syringe container may be included. When the same syringe container is attached in ward 50, the consistency of the detection information and pressing force information may be checked.

[0079] In addition 、 When the patient information such as the patient's name to be used is specified from the instruction book, the patient information can be written in the memory and used as a reference for judging the consistency with the information input in other departments. In particular, when the patient's condition changes immediately before the infusion or when the test results are available, the instructions need to be changed. The above shipment is often performed on the day of drug injection, but the drug is often adjusted and the IC tag is written on the previous day. For this reason, when the drug information needs to be changed based on the condition or test results, the syringe container is often sent to the ward in the normal procedure. On the other hand, the pump device is often shipped on the same day, and information can be written directly to the memory of the pump device without using a server, so that emergency changes can be easily handled. For this reason, it is preferable to configure the doctor's terminal 202 to generate change information and transmit the change information to the drug room, equipment room, and ward, as shown in FIG. 10. If the change information is not transmitted to each department, it is possible to easily detect and confirm this, and the occurrence of an accident can be prevented.

[0080] Thereafter, in accordance with a request, instruction, or the like from the ward 50, the syringe pump with the prescribed information written therein is transported to the ward 50 (S204). In the case of a patient who is already using a syringe pump, there are cases where only the syringe container is transported to the ward 50. If an abnormality occurs in the device or the like between the end of the above-mentioned operation check and the time when the power switch is turned on in the ward 50 (YES in S205), for example, if the device is dropped to the floor during transport, the abnormality information detection means 32 detects that an impact force equal to or greater than a prescribed value has been applied, and the abnormality information is written to the storage means 21 (S206).

[0081] When the power switch of the syringe pump 3 transported to the ward 50 is turned ON (S207), if the abnormality information has been written (YES in S208), a warning is issued (S209). The warning is issued by displaying it on the display means 22. If a warning is issued, there is a risk that the syringe pump will not operate normally, so the syringe pump is returned to the equipment room and replaced with a new syringe pump (S210).

[0082] If there is no abnormality information (NO in S208), the syringe container 2 is attached to the syringe pump 3 (S111), and the required piping, etc. is performed. Note that the display of the abnormality information is not limited to only the above timing, and can be set according to the type of abnormality information.

[0083] The operation procedure in the ward 50 will be described below with reference to FIG. 11. In the ward 50, first, an infusion pump operation check (S301) is performed. The operation check can be performed by a nurse or the like operating the switch of the pump device in a predetermined procedure, or it can be performed automatically by writing a check program in the storage means or the like. When a nurse or the like performs a check operation, it is preferable that the operating procedure and the like are displayed on the display device, and a confirmation signal for normal operation and the like are stored in a storage means (memory).

[0084] The check items for the above operation check include items necessary for determining whether the syringe pump is operating normally, such as the installation state of the syringe container, operation check of each part, remaining battery level, etc.

[0085] If normal operation cannot be confirmed in the above operation check (NO in S302), a warning is displayed (S303), and the operation of the syringe pump 3 is stopped (S304). Thereafter, the syringe pump is replaced, etc., as necessary.

[0086] After the operation check confirms that the operation is normal (YES in S302), confirmation items as shown in FIG. 7 are displayed on the display means 22 based on the information written in the IC tag 14 (S305). As shown in FIG. 7, patient information such as the patient's name and infusion information such as the infusion drug name are displayed, and if the information is in accordance with the instructions prepared by the doctor, the confirmation buttons 23a and 23b are operated (YES in S306). This allows the patient's name and other information to be confirmed reliably. The confirmation items displayed on the confirmation screen are not particularly limited, and can be changed or added as necessary. In particular, in the present invention, the required confirmation items can be easily set and confirmation input can be recorded, so that confirmation items can be set according to the patient and type of infusion, allowing a reliable confirmation operation to be performed. In addition to the confirmation items, the display means 22 can be set to display the general prescription of the drug as necessary. In particular, in this embodiment, if there is a change in the drug information after the initial drug information and other information are written in the IC tag of the syringe container, the change information is displayed. This allows the drug and injection conditions to be reconfirmed. Furthermore, the change information is also sent to the equipment room, and if there are discrepancies in the information written in multiple departments, the system can be configured to stop operation of the equipment until the information is confirmed and corrected.

[0087] In this embodiment, a required display item designation means 44 is provided for adding required display item information from among the written information. The required display item designation means 44 adds information designating the required items in the server 6 or the like, and is controlled by a program provided in the control signal generation means 30 of the syringe pump 3 or by a program provided in the storage means 21 to display the required display items preferentially. Note that for items other than the required items, a display information selection means is provided that allows selective display by a selection operation by a staff member or the like. For this reason, when a nurse or the like has doubts about the operation of the drug or the syringe pump, it is possible to easily check them. In addition, although it is considered that the items to be checked differ depending on the peculiarities of the infusion, in this embodiment, it is possible to specify the required check items and display them on the display means 22 for checking.

[0088] In addition, while conventionally, confirmation was done by comparing the contents of the instruction sheet with the contents written on the label of the syringe container and the patient information of the ward, this system can compare not only the information written on the label but also the information written on the instruction sheet written on the IC tag in the drug room, improving reliability. Furthermore, even if there are changes in the information, it can be easily confirmed whether the changes have been reflected.

[0089] If the confirmation buttons 23a, 23b, and 23c are not operated (NO in S306), a warning is displayed (S307), the confirmation items are displayed again (S305), and the user is not allowed to proceed to the next step unless the confirmation buttons 23a, 23b, and 23c are operated.

[0090] After operating the confirmation buttons 23a, 23b, and 23c (YES in S306), the settings for the infusion described in the instruction sheet are made (S308). The settings are, for example, as shown in FIG. The infusion volume, infusion rate, etc. are set as shown in FIG. 1. The infusion volume and infusion rate are written in the IC tag in the drug room, so the consistency between the contents written in the drug room and the contents input by the nurse in the ward is automatically determined (S309). That is, if there is a mismatch between the numerical value written in the instruction sheet and the set numerical value (NO in S309), a warning is issued (S310) and the infusion setting is requested to be set again (S308). This effectively prevents errors from occurring in the infusion infusion setting numerical values. If there is no consistency, the doctor who prepared the instruction sheet is asked to confirm, and if there is no problem, the warning can be cancelled. If there is the above change information, the above operation is performed based on the change information.

[0091] If the values ​​are consistent (YES in S309), the signal generating means 33 of the control signal generating means 30 generates a control signal for operating the drive control means 29 (S311). After that, an indication that injection is permitted is displayed (S312), and the start button is operated (S313) to start the injection of the infusion (S314). The above-mentioned set values ​​and whether or not the confirmation items have been confirmed are output to the storage means 21 or the IC tag 14 by the execution information output means 34 together with execution information for the subsequent injection process, and are stored therein (S315). Also, it is possible to configure the system so that the patient's condition and the operation of the syringe pump device are checked during the injection, and abnormal information is detected and a warning is issued.

[0092] As shown in FIG. 12, after a display indicating that a predetermined injection process has been completed (S401), the staff or the like checks for the disappearance of the infusion in the syringe container 2 to confirm the completion (YES in S402). If the predetermined amount of infusion has not been lost (NO in S402), some abnormality may have occurred in the syringe pump or the like, so a confirmation operation is performed (S404), and the remaining amount of infusion, etc. is input from the input means and recorded as abnormality information in the IC tag or the like. Note that even if a preset process is not performed, the injection can be terminated by forced termination. Note that after completion, it is also possible to configure the display device to display an item for checking whether there is an abnormality in the patient's condition or an input screen for the remaining amount of infusion, etc., to confirm that there is no abnormality. It is preferable to configure the device to output the completion time to the IC tag 14 or the storage means 21 when confirming the completion. It is also possible to configure the device to display a confirmation screen for confirming the patient's condition after completion of the injection and record the patient's condition.

[0093] After the completion is confirmed, the completion time is recorded (S403), the syringe container 2 is removed from the syringe pump 3 (S406), the syringe container 2 is returned to the medicine room, and the syringe pump is returned to the equipment room. In the medicine room, the execution information written in the IC tag 14 and the like are taken out and stored in the server 6 (S408). In this case, it is verified again whether the information output by the execution information output means and the information written in the IC tag based on the instruction book, that is, the executed information and the information written in the instruction book, are consistent (S409), and if there is no consistency, a warning is issued (S410). For example, if for some reason the data on the actual injection amount and injection speed of the medicine differs from the instruction book, it becomes possible to investigate the cause based on the above data.

[0094] On the other hand, if there is no problem with the data, the treatment is deemed to have been performed as described in the instruction sheet prepared by the doctor, and the information is transferred to and stored in the medical record (S411). This marks the end of the handling of the syringe container, and it is sent for disposal.

[0095] Meanwhile, the syringe pump 3 is returned to the equipment room 5 (S421), and information is retrieved from the storage means 21. If there is no problem with the information, for example, if the operation has been performed exactly as described in the instruction manual (YES in S423), the information in the storage means is stored in the server (S425), and handling of the syringe pump is terminated (S426). If an operation other than a normal operation has been performed, for example, the operation described on the IC tag or the contents entered from the input means, If an operation different from the above is being executed (NO in S423), a warning is issued (S424) and the cause is investigated. If the cause is found, the details are recorded in storage means 21 (S425), and the operation of the syringe pump is terminated (S426).

[0096] As described above, in this embodiment, the contents recorded in the IC tag 14, the contents input to the syringe pump 3, the contents written on the instruction sheet, etc. are compared with each other to verify their consistency. This significantly improves the safety of infusion injection.

[0097] FIG. 14 shows the functions of the server 6 installed in the pharmacy room and the server 7 installed in the equipment room.

[0098] The server 6 installed in the medicine room 6 is equipped with an IC tag writing means 40 that writes specified information to the IC tag 14, and an IC tag reading means 41 that reads the information written in the IC tag 14, as well as an information analysis means (artificial intelligence, etc.) 42 that analyzes the information read by the IC tag reading means 41 and generates specified information.

[0099] The server 6 installed in the medicine room reads information from the IC tag 14 attached to the syringe pump after the injection. The information is recorded in the patient's personal prescription database 54 and used as reference information for the next infusion injection and for determining consistency. For example, it can be configured to check interactions with other prescribed therapeutic drugs, or interactions with infusions to be administered in the future.

[0100] In the past, infusion data for patients was recorded in charts as treatment data. The data is used in various situations during patient treatment and is important data for hospitals. However, even if an infusion instruction manual is created, the details of the actual injection operation are often not recorded, and there is no sufficient verification of whether the injection operation was performed according to the instruction manual.

[0101] In this embodiment, since the execution information is recorded in the IC tag 14 or the storage means 21, it is possible to record in detail the injection work that was actually performed. Furthermore, the information analysis means 42 makes it possible to easily verify without much effort whether the injection operation was performed according to the instructions. Furthermore, since the verification can be performed automatically in a department other than the ward immediately after the infusion, it is possible to perform the verification with high accuracy without bothering nurses or pharmacists.

[0102] In addition, depending on the patient's condition, the type of infusion or the amount of infusion often changes immediately before the infusion operation, but because the execution information is recorded, it is easy to verify the circumstances under which any changes were made.

[0103] Moreover, the information analysis means 42 according to this embodiment is configured to include a determination means 43 capable of determining a predetermined consistency between the information written in the IC tag 14 and the information to be written.

[0104] As described above, the discrimination means 43 can determine the consistency between the information written by the drug manufacturer and the information written in the drug room. This can prevent mistakes such as mistaking drugs. In addition, since the consistency between the contents of the instruction sheet and the general prescription for the drug can be determined, the contents of the instruction sheet can also be checked. Furthermore, it is possible to determine the consistency between the information written in the instruction sheet and the execution information, and it is possible to verify the suitability of the operation and drug after injection, and if there is a mistake, it can be dealt with quickly.

[0105] As described above, the server 6 can write information to the IC tag 14 so that the information can be displayed on the display means 22 of the syringe pump 3. Among them, the device is provided with a mandatory display item designation means 44 for adding mandatory display item information. In other words, a large amount of information can be written on an IC tag, but it is difficult to check all of it in the hospital ward. For this reason, by designating mandatory check items, the check work can be carried out quickly.

[0106] Server 7 provided in the equipment room also includes writing means 47 for writing predetermined information to storage means 21, and reading means 48 for reading information written to storage means 21. For example, in equipment room 5, operation information of syringe pump 3 is often required to perform maintenance on syringe pump 3. In this embodiment, it is possible to write management information for the syringe pump in the equipment room, and read the operation information for the syringe pump from the execution information to provide for management of replacement of consumables, etc.

[0107] Furthermore, the server 6 is provided with a statistical information generating means 45 that can accumulate information read from the IC tag and generate statistical information for patients to whom infusion has been administered. This makes it easy to generate statistical information on infusion operations in the medical facility. In addition, by combining this information with post-infusion patient information, it becomes possible to accumulate information that can be used to configure information analysis means (artificial intelligence, etc.) 42, thereby making it possible to improve the accuracy of treatment.

[0108] The information analyzing means 42 can also be configured to compare the information written in each IC tag before injection with the statistical information to determine consistency.

[0109] On the other hand, information that includes information about patients is personal information and should not be disclosed to anyone other than those involved. For this reason, it is desirable to provide an anonymization means 46 that anonymizes the information read from the IC tag, and to configure the system so that statistical information can be generated.

[0110] The server in the equipment room 5 is also provided with a statistical information generating means 49 that accumulates the information read from the storage means 21 and generates a pump database 53 and pump statistical information 54 relating to the infusion pump device. This makes it possible to generate not only statistical information for individual syringe pumps, but also statistical information for the entire hospital, which is useful for managing syringe pumps. It is possible to generate required maintenance information from the statistical information for the syringe pump 3.

[0111] The above-mentioned medicine room server 6 and equipment room server 7 make it possible to easily manage information on infusions and syringe pumps, which is not only useful for patient treatment but also makes it possible to easily manage infusions and syringe pumps. [Industrial Applicability]

[0112] It is possible to provide a fluid infusion system that can reliably confirm information. [Explanation of symbols]
