The infusion pump system includes an infusion container filled with an infusion solution and an infusion pump device that injects the infusion solution from the infusion container into a patient. The infusion pump device can control the infusion pump that delivers the infusion solution at a predetermined injection rate, the infusion amount and the injection rate of the infusion pump, and when an abnormality occurs in the injection pressure or the injection rate of the infusion pump. It is configured with a drive control means for stopping the system.

To operate the infusion pump system, the infusion tube is connected to the patient, the infusion amount and infusion rate of the infusion are set, and then the pump device is operated. The infusion amount and infusion rate are set by the doctor or nurse based on the instructions prepared by the doctor.

Japanese Unexamined Patent Publication No. 2010-63763

Since the infusion pump device injects a drug into the patient's body, if the setting of the infusion type, the infusion amount, the infusion rate, etc. is incorrect, the patient will be greatly affected. Moreover, even if the setting is correct, if the infusion pump device or the like malfunctions, it will lead to a serious result as well as the setting error. Furthermore, even if the settings are correct and the infusion pump device is not malfunctioning, the patient's condition will change immediately before or during infusion, and the infusion rate and infusion of the infused fluid will change. It may be necessary to change the volume or stop the infusion. For this reason, it is necessary to pay close attention to the management of the infusion pump device and the settings for use, and to carefully observe the patient's condition before and during injection.

Normally, the type of infusion solution, injection volume, injection rate, etc. are set by the drug company that manufactures the infusion solution as a standard prescription, and then the doctor sets the prescription such as the infusion solution type and specific injection volume according to each patient. It is often set and treatment instructions are created based on it. In large hospitals, the above instructions are usually sent to the drug management department (for example, the drug room), where the drug management department prepares an infusion container filled with the prescribed infusion solution and puts it in the ward where the target patient is housed. Be transported. In addition, the infusion pump device is managed by a material management department (for example, an equipment room), and after inspection and maintenance, it is transported to the ward based on the instructions and the like. Then, in the ward, the infusion container is attached to the infusion pump device, and the infusion solution is injected into the patient. The operation of the infusion container and the infusion pump device is often performed by a nurse or the like based on the instructions of a doctor.

In a system like the above, the drug room for adjusting drugs such as infusions, the equipment room for managing infusion pumps, and the department (ward) that actually injects infusions into patients are installed separately. In many cases. In addition, in each department, the person in charge of each department performs the work. For example, a doctor who gives an instruction for infusion adjustment, a nurse who injects an infusion solution into a patient, a pharmacist who prepares the infusion solution, an engineer who manages an infusion pump device, and the like work in different places. Therefore, if information on the type of infusion, the amount of infusion, the infusion rate, and the like for a predetermined patient is not accurately transmitted, a serious accident may occur. In addition, the infusion pump is inspected and maintained in the equipment room, but it is necessary to confirm whether the infusion pump is properly inspected and maintained and operates normally in the ward before infusion. For this reason, each department repeatedly confirms information based on the above instructions, inspection / maintenance records, etc., and prevents accidents such as mistakes and setting mistakes.

The above confirmation work is repeated in each department, but it cannot be said that there is a possibility that the instructions will be misread. In addition, the contents that can be described in the above instructions and the items and contents that can be confirmed by each department are limited. For example, the instruction sheet does not include history information of the patient's drug administration so far, and the nurses in the ward can confirm whether the instruction content described in the instruction sheet is correct. , It is necessary to refer to the administration record of the previous drug. In addition, whether or not the infusion pump operates normally is a matter managed by the materials department and is not described in the above instructions. In the ward, it is necessary to inject the infusion solution to a predetermined patient after confirming the information on the above infusion solution and confirming that the infusion pump operates normally.

The confirmation of the infusion information and the like is often performed by comparing the information described in the instruction sheet with the information described in the infusion container and the patient information such as the patient name. In addition, the infusion pump device must be set based on the above information. Therefore, the possibility of a confirmation error and the possibility of a setting error of the infusion pump device cannot be completely excluded.

The present invention can efficiently transmit, exchange, and confirm information about an infusion solution and a patient to which the infusion solution is applied in various tissues inside and outside the hospital that handle an infusion container and an infusion pump device, and uses the infusion solution. An object of the present invention is to provide an infusion pump system for improving the accuracy of confirmation work associated with treatment and preventing mistakes and obstacles in infusion treatment using these devices.

The present invention relates to an infusion pump system including an infusion pump device capable of mounting an infusion container filled with an infusion solution and injecting the infusion solution of the infusion container into a patient. The infusion container is configured to include an IC tag on which predetermined information is written. The infusion pump device includes an IC tag reading means for reading information stored in the IC tag, a pump means for discharging the infusion solution in the infusion container, a pump driving means for driving the pump means, and the pump driving means. A drive control means for controlling and discharging an infusion solution of a predetermined flow rate, a container information detecting means for collecting container information from an attached infusion container, an input means for inputting patient information and infusion information, and a predetermined information are displayed. By the display means, the drive control means, the container information detection means, the input means, the control signal generation means for generating the control signal for controlling the display means, the control signal generation means, and the drive control means. An execution information output means capable of outputting the executed execution information, an abnormality information detecting means capable of detecting an abnormality in the system and outputting the abnormality to the drive control means or the control signal generation means, and controlling the operation of the pump drive means. It is configured with a storage means that can store the information of. The control signal generating means is predetermined based on the information stored in the IC tag, the information input from the input means, the information stored in the storage means, and the two or more information obtained from the container information. It is configured to be able to generate control signals. Then, based on the control signal, the drive control means, the input means, the display means, and the abnormality information detecting means are operated.

The type of infusion container is not particularly limited. For example, it may be in the shape of a bag or in the form of a syringe.

An IC tag is provided on the infusion container. The IC tag is a kind of storage device, and can electromagnetically record and read information. The type of the IC tag is not particularly limited, but at least a server or the like installed in the infusion management department of the hospital may be capable of writing patient information or the like.

The place where the IC tag is attached to the infusion container and the person who attaches the IC tag are not particularly limited. For example, an IC tag may be attached in the purchasing department of the hospital, or an IC tag in which standard infusion information is written in the drug maker can be attached and delivered to the hospital. Further, in the hospital, the department in which the device for writing information on the IC tag is installed is not particularly limited. Install a writing device in the drug room, write the prescribed information of the infusion solution at the drug manufacturer, and add the patient information created by the doctor etc. and the information on the infusion rate etc. to the IC tag attached to the infusion container and write it. It can also be configured.

In addition, in hospitals, various information should be written to the IC tag attached to the infusion container in the drug room that adjusts the infusion, the equipment room that manages the infusion pump device, and the ward that injects the infusion into the patient. Can be configured. When the infusion container provided with the IC tag does not pass through the equipment room that manages the infusion pump device, the infusion pump is input by inputting predetermined information such as operation information into the storage means of the infusion pump device in the equipment room. When the infusion container is attached to the device, the information stored in the storage means of the infusion pump device and the IC tag can be integrated and used as integrated information.

The part of the infusion container to which the IC tag is provided is not particularly limited, but the information stored in the IC tag is read from the IC tag reading device provided on the infusion pump device side while attached to the infusion pump device. , It may be attached to the part where writing can be performed. The information stored in the IC tag can be read out without the infusion container being attached to the infusion pump device. For example, a general-purpose IC tag reading device that can be connected to the infusion pump device with a cord or the like can be separately prepared so that information can be read by holding it over an IC tag provided in the infusion container or the like. This makes it possible to deal with the case where a drug is added to the infusion container and used before the infusion container is installed in the infusion pump device in the ward.

The amount of information that can be stored in the IC tag is much larger than the amount of information that is written on a paper medium such as an instruction sheet, and complicated information can also be stored. Therefore, it is possible to store information that has not been described in the instruction sheet so far. The type of information stored in the IC tag is not particularly limited. Information necessary for infusion injection such as information on infusion, information on injection rate, information on injection amount, patient information, etc. can be written. In addition, when the infusion pump device is provided with an IC tag writing means, not only the above information but also execution contents such as execution information during infusion injection and confirmation information after completion of infusion infusion, which are not described in conventional instructions, etc., are provided. Can be written. In addition, the control information of the infusion pump device is stored and the infusion pump device is configured to perform a predetermined operation, and the operation confirmation information of the infusion pump device before infusion injection and the abnormality information of the device are written. it can.

The infusion pump device is configured to include an IC tag reading means for reading information stored in the IC tag. The configuration of the IC tag reading means is not particularly limited. Since the IC tag reads information electronically in a non-contact manner, by installing a reading means at or near the site where the infusion container is attached, the information stored in the IC tag can be reliably read. It can be sent to the storage means or drive control means of the infusion pump device. Further, since the information can be read without contact, it can be built in the device.

The configuration of the pump means is also not particularly limited. A roller type pump means using a tube, a peristaltic type pump means, a syringe type pump means, or the like can be adopted. The configuration of the pump driving means can also be set according to the type of the pump means.

The configuration of the pump driving means is also not particularly limited. For example, various types of electric motors can be used to configure the pump drive means. Further, various actuators using air pressure or hydraulic pressure can be adopted as the pump driving means.

The pump drive means is controlled by the drive control means. The drive control means not only starts and stops the pump drive means, but also drives the pump drive means so that the infusion solution is injected at a predetermined flow rate. Further, it can be configured to perform a test operation of the infusion pump device based on a predetermined signal and to stop the pump driving means based on the abnormality information. Further, the information actually driven and controlled by the drive control means is output as execution information and written in the storage means or the like.

When an electric motor is adopted as the pump drive means, a known motor control device can be adopted as the drive control means. The drive control method is not particularly limited, and feedback control and a servo mechanism can be adopted. Further, a known control device can also be adopted when a pneumatic or hydraulic actuator is adopted.

The container information detecting means detects container information from the infusion container to be mounted. The size and form of the infusion container is determined by the amount of injection and the type of drug to be filled. For example, a large infusion drug is contained in a large infusion container, while a low infusion drug is contained in a small infusion container. Therefore, a part of the information about the infusion solution can be obtained by detecting the size, form, etc. of the infusion container with a sensor or the like. By comparing the information obtained from these containers with the information written on the IC tag and the information input by the input means and confirming the consistency, it is possible to check whether the type of drug adopted and the injection amount are correct. Can be verified. As a result, safety can be enhanced.

The configuration of the container information detecting means is not particularly limited. For example, in the case of an infusion container having the form of a syringe, a sensor or the like that detects values such as the thickness and length of the syringe to be mounted can be adopted. In addition, information on the injection amount can be detected by detecting the weight of the infusion container. Further, in the case of a syringe-shaped container, the pressing force of the pusher and the position can be measured and used as container information or drug amount information. The container information is not limited to that relating to the morphological dimensions of the infusion container, and may be configured to collect container information from, for example, a pattern or color attached to the surface.

The input means is configured so that at least patient information and infusion information can be input in the ward. For example, it is configured so that the infusion rate and the like can be input based on a doctor's instruction sheet and the like. In the present invention, since the infusion information and the patient information are stored in the IC tag, when the nurse or the like inputs the patient information and the infusion information in the ward, the information described in the IC tag and the information in the above ward are input. It is possible to automatically verify the consistency of the information. The configuration of the input means is not particularly limited. For example, a touch panel device such as a liquid crystal that is integrally configured with the display means can be adopted. Further, the input information is not particularly limited, and it can be configured to output a confirmation signal by displaying the confirmation items before the operation of the infusion pump device and pressing the confirmation button or the like after the confirmation. Then, it is desirable to output this confirmation signal to the control signal generation means, and after receiving this signal, generate the control signal and start the injection. Furthermore, there may be cases where the test results are obtained immediately before the infusion treatment is performed and it becomes necessary to change the type of drug or infusion conditions, or the patient's condition suddenly changes. In such a case, the input means is also used when it is necessary to change the information written in the IC tag. In addition, when the change information has already been written, it can be configured to input for confirming the change content.

Conventionally, confirmation work has been performed mainly on predetermined items such as infusion type, infusion rate, and infusion amount based on the instruction sheet, but the items to be confirmed differ depending on the infusion type, patient status, and medical institution. In some cases. In such a case, the confirmation work is facilitated by preferentially displaying the information that needs to be confirmed and by configuring the infusion pump device to start based on the presence or absence of confirmation of the information. It also improves safety. Therefore, among the information to be written, the essential display item designation means for adding the essential display item information is provided, and the display means of the infusion pump device preferentially displays the essential infusion information based on the essential display item information. Can be configured to. On the other hand, it is also possible to store the general prescription of the drug in the IC tag and provide a display information selection means capable of selectively displaying the infusion information when a question arises in the prescription of the drug or the like in the ward. ..

In the present invention, an execution information output means capable of outputting execution information of the infusion pump device executed by the control signal generation means and the drive control means is provided. The above-mentioned execution information is the treatment information actually performed for a specific patient, and is also the operation information of the system and the infusion pump device. In particular, in the infusion operation, the type of infusion, the infusion amount, and the like are often changed immediately before depending on the patient's condition and the like. In such a case, the change instruction is often given by an instruction sheet or the like, but in many cases the drug has already been transported to the ward, and it is often difficult to write information on the IC tag in the drug room or the like. .. In addition, depending on the patient's condition, the injection may be discontinued in the middle. Therefore, it is necessary to verify after the fact whether or not the infusion solution was performed according to the prescribed instructions. By accumulating the above information, information for 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 there is a mistake, it is possible to verify whether there is a problem immediately after injecting the infusion solution, and it is possible to respond promptly.

In addition, since information in the execution process can be collected, it is possible to detect abnormal operation of the device and predict the life of the device by collecting and analyzing the operation information of the device and the system. The execution information is stored in the storage means and the IC tag. As the above information, for example, not only the infusion amount (discharge amount) of the infusion solution, the infusion rate, the infusion pressure and the like, but also the drive time of the pump device, the resistance change of the drive means, and the like can be recorded. Not only can this information be used for setting operations during subsequent injection, but also the information output in real time is compared with the past information recorded on the IC tag or the like to detect abnormalities in the device. It can also be configured as follows.

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 adopted. Since the IC tag is provided in 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 above-mentioned storage means, it is possible to create management data of the infusion pump device and use it for maintenance and the like. It is also possible to construct a system that can share the information injected from the IC tag of the infusion container with other departments.

The abnormality information detecting means detects an abnormality in the system and outputs it to the driving control means or the control signal generating means to control the operation of the pump driving means. The information detected as a system abnormality is not particularly limited. For example, it can be configured to detect an abnormality in the infusion pump device, an abnormality in the power supply, or the like. Further, it can be configured to detect the injection pressure, the displacement of the infusion container (abnormality of the mounting state, etc.) and the like. Further, the drive control means can be configured to be directly controlled by the information output by the abnormality information detecting means, and the control signal generating means generates a predetermined control signal based on the output information. It can also be configured to do so. Further, it can be configured to detect not only an abnormality during operation of the infusion pump device but also an abnormality during non-operation. For example, when an impact is applied to the infusion pump device during storage or transportation, an abnormality signal is generated and stored in the above storage means, and an abnormality is displayed when the infusion pump device is operated. It can be configured to be displayed on the means.

The control signal generating means is configured so as to not only generate a signal for driving the pump driving means but also analyze various information to determine whether or not the infusion pump device can be operated. Further, the control signal generating means can generate various control signals related to the display contents of the information stored in the IC tag or the like, a control signal for recording the execution information performed by the infusion pump device, or the like. It is composed.

As the storage means, various storage devices can be adopted as long as they can write and read information. For example, a known flash memory can be adopted. Further, the present invention is not limited to a fixed one, and for example, a detachable one such as an SD card can be adopted. Further, an IC tag different from the one attached to the infusion container can be adopted as the storage means.

The information stored in the storage means is not particularly limited, and not only the information necessary for driving the infusion pump device and the maintenance information of the infusion pump device but also the history information of the target patient is stored in advance. You can also leave it. Further, the information stored in the IC tag attached to the infusion container can be taken into the storage means in the infusion pump device, integrated with the information stored in the IC tag, and configured to perform various controls. .. Further, contrary to the above, the information stored in the storage means of the infusion pump device can be taken into the IC tag attached to the infusion container and integrated. Infusions are often ready the day before. On the other hand, the patient's condition changes from moment to moment. In particular, there are many cases where the condition changes or the test results become clear in the morning when the treatment is performed. In such cases, the doctor may give direct oral or written instructions to the ward, but the risk of mistakes increases. Therefore, when changing the drug or injection speed instructed by the doctor, it is preferable to transmit the information from the doctor terminal to the drug room and the equipment room to update the instruction content. 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 transportation to the ward, and the information written on the tag of the infusion container and the storage means of the infusion pump device are stored. The information stored in may not match. In such a case, if there is a discrepancy 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 determined whether or not there is updated information, and the infusion solution is infused. When the information is updated, it is preferable to display the fact on the display means of the infusion pump device, confirm the updated contents, and then operate the device. In addition, if the information written in the IC tag of the infusion container and the storage means of the infusion pump device are inconsistent, the infusion pump device is controlled so as not to operate until confirmation and correction are performed. , Safety is also improved.

The control signal generating means is based on the information stored in the IC tag attached to the infusion container, the information stored in the storage means of the infusion pump device, and the information input from the input means of the infusion pump device. Control signals can be generated. Further, the control signal generating means is configured to be able to generate a predetermined control signal based on the container information and the information obtained from the abnormality information detecting means.

Based on the control signal, the drive control means, the input means, the display means, and the abnormality information detecting means are operated. The type of the control signal is not particularly limited. For example, in order to control the infusion rate of the infusion solution, a control signal for controlling the speed of the driving means can be generated. In addition, it is possible to generate a signal for controlling the operation of the display means and the input means. For example, when an abnormal signal is detected or when each information is inconsistent, it can be configured to display that the display means is inconsistent. Further, if the signals from each means are inconsistent, the operation may be stopped and a warning may be displayed on the display means. In particular, when the 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 the change information is directly input from the input means of the infusion pump device in the ward. , It is preferable to configure the above change information so that it can be verified whether or not there is a problem. For example, it is desirable to store the standard application conditions of the drug in the above IC tag or storage means so that the contents can be compared with the input contents.

The infusion pump device may be provided with an IC tag writing means for writing predetermined information on the IC tag. In particular, if the patient's condition changes immediately before infusion, the infusion drug and amount are often changed. The change is made based on the instruction sheet, but the confirmation work can be surely performed by writing the changed content in the storage means of the infusion pump device. In addition, execution information can be reliably recorded. The IC tag writing means can be configured not only to be able to write information via the input screen (display screen) of the infusion device, but also to automatically store the information output from each means of the infusion pump device. it can. For example, the numerical information input from the input means can be configured to be automatically written in the IC tag. The information stored in the storage means of the infusion pump device can be configured to be automatically transferred to the IC tag. The IC tag writing means can also be controlled by the control information generated by the control signal generating means.

In the ward, various information can be written to the IC tag via the IC tag writing means. Not only the patient name but also the patient information such as the body temperature information previously recorded on the paper medium can be written. In addition, confirmation items can be displayed on the display means, and check information to the effect that the confirmation items have been confirmed can be written. Further, the execution information and the abnormality information can be written in the IC tag or the storage means during the operation of the system or after the operation of the system is completed.

The control signal generating means compares two or more of the information stored in the IC tag, the information stored in the storage means, the information input from the input means, and the container information. Therefore, it is possible to provide a discriminating means capable of discriminating whether or not it has a predetermined consistency. The discriminating means is configured to include a microcomputer, and can be configured to include a required program and information data stored in the storage means. The combination of information used for the above determination is not particularly limited, and can be set according to patient information, the type of infusion, and the like. Further, the type of control information generated according to the result of the determination means is not particularly limited. For example, when there is inconsistency in the information, it is possible to generate stop command information of the device, generate display information related to the information, and display the information on the display means or the like. In addition, when an injection amount or injection rate that deviates from the standard prescription is input, a confirmation screen can be displayed to confirm the suitability.

In addition, it can be configured to display a confirmation screen for confirmation when there is a large change in comparison with the past injection history of the patient. By providing the above-mentioned discriminating means, the confirmation work can be facilitated and the safety can be significantly improved.

It is necessary to write instructions such as injection amount and injection speed on the IC tag based on the instructions of the doctor. Therefore, the system can be configured to include a server device capable of writing predetermined information in the IC tag and outputting and recording the information written in the IC tag. Further, as described above, the IC tag can be attached at a drug maker and a standard prescription or the like can be written so that information for a specific patient such as an injection amount and an injection rate can be added at a hospital.

The department in which the server device is installed is not particularly limited. It can be installed not only in the drug room and equipment room, but also in the department that purchases infusion containers. Then, each department can be configured to input predetermined information into the IC tag or the storage means.

The server device includes an IC tag writing means for writing predetermined information on the IC tag and an IC tag reading means for reading the information written on the IC tag. Further, it is configured to include an information analysis means (artificial intelligence) that analyzes the information read by the IC tag reading means and generates predetermined information.

As the information analysis means, a discriminating means capable of discriminating a predetermined consistency between the information written in the IC tag and the information to be written can be provided. For example, if the doctor's instructions regarding the injection rate and injection amount differ from the standard prescription such as the infusion administration method specified by the drug 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 to the IC tag. The inconsistency determination information is not only between two or more pieces of information to be written in the IC tag, but also inconsistency between the information already written in the IC tag and the information to be written in the future, and already written in the IC tag. It can be configured so that inconsistencies between the information received can be determined.

The control method of the infusion pump device according to the present invention includes information written in an IC tag provided in an infusion container mounted on the infusion device and information written in a storage means provided in the infusion device. , And is executed based on the information input at the time of infusion. The IC tag information input step of writing predetermined information to the IC tag, the storage means information input step of writing predetermined information to the storage means, and the infusion pump device input step of inputting predetermined information to the infusion pump device are Since it is performed in a separate department, not only is there a time lag, but input errors are likely to occur. The present invention includes an input information comparison step of comparing the information input in each of the above steps, and when inconsistency is detected in the information input in the above input information comparison step, predetermined information is output and the above is described. It can be configured to stop control of the infusion pump device. Therefore, the safety of infusion therapy is significantly enhanced. Further, the safety can be further improved by configuring the department in which the server is installed so as to confirm the consistency with the information in other departments.

When the maintenance work of the pump device is performed, the predetermined maintenance work completion information is written in the storage device, and the maintenance work completion information is displayed on the display means at a predetermined timing. Is desirable. For example, when the infusion pump device is started, it is desirable to display that the above maintenance work has been completed successfully, input that the confirmation has been completed, and then drive the drive means. Further, when there is an abnormality in the maintenance work completion information, it is preferable to set so as not to generate the control signal. This makes it possible to check the state of the infusion pump device before injecting the infusion solution into the patient, and it is possible to improve safety.

The server device can write various information that can be displayed on the display means of the infusion pump device on the IC tag. Various display information can be written in the IC tag, but it is not necessary to display all of them. Therefore, among the written information, it is desirable to automatically display the information regarding the essential confirmation items that need to be confirmed. In order to specify the information related to the above-mentioned required items, a required display item designation means for adding the required display item information is provided. The above-mentioned mandatory display item designation means is configured so that information that must be confirmed must be specified depending on the type of infusion solution and the patient. The display means of the infusion pump device displays essential infusion information based on the essential display item information. On the other hand, a display information selection means capable of selectively displaying infusion information other than the essential items can be provided. As a result, when a question arises in the ward, the question can be quickly and easily resolved.

It is desirable to configure the server device so that it can accumulate the information read from the IC tag and generate statistical information for the patient to whom the infusion solution has been applied. The above statistical information can be used not only for treatment but also as background information in the next infusion infusion. For example, the information analysis means can be used to compare the information written in each IC tag with the statistical information to determine the consistency.

On the other hand, there are cases where we want to collect a wide range of information about infusions. However, the information recorded on the IC tag is personal information and cannot be used for any purpose other than the treatment of the patient. Therefore, the information analysis means can be configured so that the information read from the IC tag can be anonymized and statistical information can be generated. This makes it possible to obtain general statistical information when using an infusion solution. In addition, since information can be anonymized when reading information from the IC tag of the infusion container after use, the risk of leakage of personal information can be reduced. Furthermore, by combining patient cases and therapeutic effects, it can be utilized as statistical information in each medical institution.

In addition, the information analysis means can be configured to accumulate information read from the storage means and generate statistical information about the infusion pump device. For example, it is possible to collect and manage information on the driving time and the like. As a result, it can be used for maintenance of the pump device and the like. Further, the information analysis means can be configured to generate necessary maintenance information from the statistical information of the infusion pump device.

It is possible to improve the safety of not only the infusion pump device but also the entire infusion pump system.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The infusion pump system according to the present embodiment is not limited to infusion as a therapeutic agent or an infusion pump device as an apparatus, but various information regarding the infusion and the apparatus in organizations inside and outside the hospital that handle these. It includes a processing device and method for processing information and the like performed using the above-mentioned infusion and equipment. In the present embodiment, a syringe container is adopted as the infusion container, and a syringe pump capable of pressing the pusher of the syringe at a predetermined speed is adopted as the infusion pump device.

As shown in FIG. 1, in the infusion pump system 1, a syringe container 2 as an infusion container filled with an infusion solution and the syringe container 2 are mounted, and the pusher 10 of the syringe container 2 is pushed to push the infusion solution. It is configured to include a syringe pump 3 as an infusion pump device for injecting into a patient from the syringe container 2. Further, in the drug room 4 and the equipment room 5 that handle the syringe container 2 and the syringe pump 3, the servers 6 and 7 that handle the information about the syringe container 2 and the syringe pump 3 are included.

As shown in FIG. 2, the syringe container 2 has a cylindrical outer cylinder 8 filled with an infusion solution and an oval flange portion formed at the base end portion of the outer cylinder 8 so as to extend outward in the radial direction. 9 and a pusher 10 inserted from the base end portion into the outer cylinder are provided, and the syringe container 2 itself constitutes the pump means. The entire syringe container 2 is formed by resin molding, and a discharge port 11 to which an infusion tube is connected is formed at the tip of an outer cylinder. Further, a gasket 12 for sealing between the tip of the pusher 10 and the inner surface of the outer cylinder is provided, and a pusher flange portion 13 is provided at the base end of the pusher. There is.

In the present embodiment, as shown in FIG. 2, the IC tag (REID) 14 is attached to the outer surface of the outer cylinder. The IC tag 14 is a kind of tag having a built-in IC chip capable of wireless communication. Various electronic information is written in the IC tag 14, and the information can be written and read by short-distance wireless communication using an electromagnetic field, radio waves, or the like.

For example, as shown in FIG. 9, infusion information, patient information, infusion information, history information, caution information, and the like can be written in the IC tag 14. The infusion information may include the name of the infusion, standard use information of the infusion, and the like. In addition, the patient information can include information necessary for applying the infusion, such as the patient's name, age, body weight, and disease name. The injection information may include the injection amount, injection rate, and the like described in the instruction sheet prepared by the doctor. In addition, the past history information may include the type of infusion solution in the past, the injection amount, the injection rate, the injection date and time, and the like. In addition, the above caution information can include the condition of the patient at the time of injecting the infusion solution. For example, when the body temperature or blood pressure exceeds a predetermined range, information such as instruction information for not injecting the infusion solution can be included.

In the infusion solution delivered to the hospital while being filled in the syringe container 2, the drug maker 15 attaches the IC tag 14 to the syringe container 2, and the drug maker provides information such as the name of the infusion solution and the general prescription. It is input to the IC tag 14. Then, after the syringe container 2 is delivered to the hospital, the applied patient information and the like can be added to the IC tag 14.

As shown in FIGS. 3 and 4, the syringe pump 3 holds and pushes the syringe outer cylinder holding means 16 for holding the outer cylinder 8 of the syringe container 2 and the pusher flange portion 13. , The pushing means 17 for discharging the infusion solution is provided.

The syringe outer cylinder holding means 16 includes an outer cylinder holding portion 16a formed by providing a substantially cylindrical inner surface-shaped mounting surface 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 the outer cylinder holding portion 16. A flange holding portion 16d formed between a pair of standing wall portions 16b and 16c provided on the base end side of the portion 16a and capable of inserting and hooking the flange portion 9 and a syringe outer cylinder 8 on the above-described mounting surface. It is configured to include a pinching lock mechanism 18 that can pinch between the two.

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

The pinching lock mechanism 18 is configured to include an arm portion 18a that holds the syringe outer cylinder 8 by pinching it with the above-mentioned mounting surface. The arm portion 18a is configured so that the syringe outer cylinder 8 can be elastically pressed. Further, in the present embodiment, the pinching lock mechanism 18 constitutes a container information detecting means 20 capable of detecting the size (outer diameter) of the syringe by detecting the rotation angle of the arm portion 18a. ..

The container information detecting means 20 includes a variable resistor (not shown) whose resistance changes according to the rotation angle of the arm portion 18a, and an infusion solution (not shown) based on the output from the variable resistor. -It is configured so that the type, capacity, etc. of the syringe container 2 can be identified from the capacity table. The infusion-capacity table is stored in the storage means 21 provided in the syringe pump or the IC tag 14, and the outer diameter of the syringe outer cylinder is measured by the detection resistance of the variable resistor, and the outer diameter is set to this outer diameter. It is configured so that the corresponding syringe capacity and the like can be read from the infusion-volume table. Further, in the present embodiment, the position of the pusher 10 can be detected from the position of the slider 19. Based on this information, the amount of infusion solution filled in the syringe container 2 can be detected. In addition, the infusion-volume table is configured to detect infusions that may fill a syringe of the volume detected by the syringe detecting means. Further, by comparing the content read from the infusion-volume table based on the data detected by the container information detecting means 20 with the infusion information written in the IC tag, the syringe container and the infusion are matched. It is possible to determine the sex and prevent the drug from being mixed up.

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 various information described above. Further, the storage means 21 also stores information on the operation inspection of the infusion pump performed in the equipment room, and can be displayed on the display means 22 provided on the upper surface of the syringe pump as needed. Further, in order to write information on the IC tag of the syringe container 2 filled with the infusion solution, it is necessary to use the server 6 in the drug room, and it is necessary to complete the preparation of the syringe container the day before the drug injection. On the other hand, information can be directly written to the storage means 21 of the syringe pump 3 from the input means of the syringe pump main body in addition to the server 7 in the equipment room. In addition, preparation of the syringe pump is often performed on the same day. For this reason, change information and additional information can often be added to the storage means 21 before the syringe pump is transported to the ward. Therefore, when change information occurs on the day of drug injection, this information is transmitted not only to the drug room but also to the equipment room, and the information is written not only in the IC tag of the syringe container 2 but also in the storage means 21. It is preferable to do so.

Further, the syringe pump 3 is provided with an abnormality information detecting means 32 that outputs abnormality information, for example, when an impact or the like is applied during transportation. The abnormality information detecting means 32 can be configured by using various acceleration sensors and the like. When the impact is applied, the abnormality signal is output from the abnormality information detecting means 32 even when the power of the syringe pump 3 is turned off, and the abnormality information is output to the storage means 21 or the like. It will be remembered.

An appropriate portion of a drive mechanism (not shown) for driving the slider 19 is provided with a push force detecting means (not shown) capable of measuring the push force of the pusher 10. The pushing force detecting means constitutes a part of the container information detecting means 20, and is, for example, an elastic piece (not shown) that is elastically deformed by the pushing force from the pusher and is attached to the elastic piece. It can be configured with a resistance strain gauge. Further, the output from the resistance strain gauge can be used to detect the pushing force of the pusher and indirectly detect the injection pressure at the discharge port. Further, since it can be estimated that the pressing force in the state where the infusion solution is not injected into the patient becomes a value corresponding to the sliding resistance between the outer cylinder of the syringe container and the gasket, that is, the outer diameter of the syringe container, the syringe detecting means can be used. By combining with the information of the above, it can be used as information for determining whether or not the syringe container as a pump means is operating normally.

On the upper surface of the syringe pump 3, an operation panel 24 including a display means 22 for displaying various information and set numerical values and various operation switches 23 as input means is provided. As shown in FIG. 4, the display means 22 is composed of a liquid crystal display device and also a touch panel as an input means. For example, as shown in FIG. 7, a confirmation screen showing predetermined confirmation information is displayed, and by touching the “OK” display of the confirmation buttons 23a, 23b, 23c on the screen, the response to the displayed confirmation information is received. It is configured so that a signal (confirmation signal) can be generated. In particular, it is desirable that the type of drug is configured so that when there is change information such as the injection rate, this is displayed to alert and confirm that the setting has been changed. Further, as shown in FIG. 8, a numerical value increase switch 25 for setting a numerical value displayed on the display means 22 and a numerical value decrease switch 26 are provided on the side portion of the display means 22. The switches 25 and 26 are composed of a film switch. Although description is omitted, other switches such as a power switch are also provided on the upper surface of the syringe pump 3.

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 adjacent to the syringe outer cylinder holding means 16 and open a predetermined gap in the IC tag 14 attached to the syringe container 2. It is provided so as to face each other. The configurations of the IC tag reading means 27 and the IC tag writing means 28 are not particularly limited, and known IC tag reading and writing means can be adopted.

A drive control means 29 is provided to control the motors constituting the push means 17 (pump drive means). In the present embodiment, the speed of the motor that drives the slider 19 can be controlled, and the operation is stopped by a predetermined abnormal signal or the like. Further, the electric power for driving the motor can be measured, and when the electric power in a predetermined range is exceeded, an abnormal signal can be generated. Further, by detecting the rotation speed, the movement information of the slider, that is, the infusion speed of the infusion solution can be detected. The drive control means 29 can be configured by using various integrated circuits.

Further, in the present embodiment, the drive control means 29, the container information detection means 20, the operation switch 23, and the control signal generation means 30 for generating a control signal for controlling the display means 22 are provided. The control signal generation means 30 processes the various information described above and generates a control signal instructing the operation of each of the means.

As shown in FIG. 9, the control signal generating means 30 includes information stored in the IC tag 14, information stored in the storage means 21, information input from the input means 23, and the container. A discriminating means 31 capable of comparing two or more pieces of the container information obtained from the information detecting means 20 and discriminating whether or not the information has a predetermined consistency is provided, and the discriminating result of the discriminating means 31 Based on this, a predetermined control signal is output to each means.

Confirmation information and numerical information from the IC tag 14, the storage means 21, the container information detecting means 20, and the input means 23 including the display touch panel are input to the control signal generating means 30. The discriminating means 31 of the control signal generating means 30 confirms whether or not information that conflicts with or does not match these information is included, that is, whether or not each information is consistent. Then, after the consistency is confirmed, a control signal is output to the drive control means 29 and the like based on the information input from the IC tag and the input means.

Hereinafter, an outline of the operation of the infusion pump system 1 according to the present embodiment will be described with reference to the flowcharts of FIGS. 10 to 12.

First, an infusion instruction sheet is prepared by a doctor (S101), and the instruction sheet is submitted to the drug room and accepted (S102). The instruction sheet is often created or input by the doctor terminal 202 based on the test information 201 or the like, and the staff of the pharmacy room adjusts the drug based on the instruction sheet (S103). Normally, the infusion solution is manufactured by a drug manufacturer and filled in a syringe container (S104). After that, the IC tag 14 on which a standard prescription or the like is written is attached to the syringe container 2 (S105), shipped to the hospital, and delivered to the drug room. The staff in the pharmacy room often adjusts the infusion solution by selecting a syringe container filled with the drug described in the instruction sheet. In addition, it can be adjusted by mixing a plurality of infusion solutions in the drug room. In this case, the IC tag 14 is attached to the syringe container 2 in the drug chamber, and information such as the drug name is written. It is also possible to additionally fill an infusion container filled with a predetermined drug with another drug and add information on the additionally filled drug to the IC tag. At the manufacturing stage of the syringe container 2, an IC tag on which information is not written can be embedded in a predetermined location of the syringe container 2, and the information can be added in each of the above-mentioned departments and the like.

In the above-mentioned drug room, information about the infusion and the patient is written in the IC tag based on the instruction sheet (S106). As shown in FIG. 13, in the present embodiment, in the drug maker 15, information such as a drug name, an ingredient, and a general prescription of the infusion solution is written in the IC tag. For example, the injection amount (range of prescriptionable injection amount), injection rate (range of prescriptionable injection rate), and other general precautions are written on the IC tag at the drug manufacturer, and the syringe container is filled with the infusion solution. It is affixed to 2 and shipped to each hospital.

In the drug room 4, application information for a specific patient is added to the IC tag 14 based on a doctor's instruction (S106). As shown in FIG. 1, a server 6 capable of writing and reading information on an IC tag is installed in the drug room. Using the server 6, for example, the patient name, gender, age, injection amount, injection speed, and other precautions are added to the IC tag 14 attached to the syringe container 2. At this time, if there is inconsistency between the information input in the drug room and the information input in the drug maker (NO in S107), for example, it is written in the drug room based on a doctor's instruction or the like. If the drug name is different from the drug name of the selected syringe container, or if the injection amount, injection rate, etc. are outside the range of the injection amount or injection rate written on 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 be obliged to check with the doctor who created the instruction sheet and correct the input contents if necessary (S109).

That is, information that should be the same (including the range, etc.) is input in different departments, and a warning is issued when the input information is inconsistent. With the above method, it is possible to detect the type of drug and the injection amount of the drug that exceeds the applicable range set by the drug manufacturer, and prevent mistakes in the instructions in the instruction sheet and misunderstanding of the drug. Is possible. In addition, when the setting exceeds the applicable range set by the drug maker, it can be configured so that the above warning can be canceled by performing a predetermined operation.

On the other hand, as shown in FIGS. 1 and 10, the syringe pump 3 is first subjected to replacement of consumables and the like and various adjustments in the equipment room 5 (S201), and an operation check of whether or not the syringe pump 3 operates normally. (S202), and the check result and the check date are written in the storage means (memory) 21 provided in the syringe pump (S203).

In addition, the check information can include operation information when a predetermined syringe container is attached. For example, detection information for a predetermined syringe container, pressing pressure information, and the like can be included. Then, in the ward 50, when the same syringe container is attached, it can be configured to check the consistency of the detection information and the pressing pressure information.

In the present embodiment, the infusion information and the patient information are not written in the storage means 21, but when the patient information such as the patient name to be used is specified from the instruction sheet or the like, the patient information or the like is stored in the memory. It can also be used as a material for judging the consistency with the information written and input in other departments. In particular, if the patient's condition changes immediately before the infusion or the test result is obtained, it is necessary to change the instruction content. The above shipment is often performed on the day of drug injection, but the drug adjustment and the above IC tag writing are often performed the day before. Therefore, when it is necessary to change the drug information or the like from the condition or the test result, the syringe container is often sent to the ward by the above-mentioned normal procedure. On the other hand, the pump device is often shipped on the same day, and since information can be written directly to the memory of the pump device without using a server, it is possible to easily respond to an urgent change. Therefore, as shown in FIG. 10, it is preferable that the change information is generated by the doctor terminal 202 and the change information is transmitted to the drug room, the equipment room, and the ward. When the change information is not transmitted to each of the above departments, it is possible to easily detect and confirm the change information, and it is possible to prevent the occurrence of an accident.

After that, the syringe pump in which the predetermined information is written is conveyed to the ward 50 according to the request from the ward 50, the instruction sheet, and the like (S204). In the case of a patient who has already used a syringe pump, only the syringe container may be transported to the ward 50. Abnormality information detection means when there is an abnormality in the device or the like (YES in S205) between the end of the above operation check and the time when the power switch is turned on in the ward 50, for example, when the device is dropped on the floor during transportation. 32 detects that an impact force equal to or greater than a predetermined value has been applied, and the above-mentioned abnormality information is written in the storage means 21 (S206).

When the power switch of the syringe pump 3 transported to the ward 50 is turned on (S207), a warning is issued when the abnormality information is written (YES in S208) (S209). The warning is given by displaying on the display means 22. If a warning is issued, the syringe pump may not operate normally, so it is returned to the equipment room and replaced with a new syringe pump (S210).

When there is no abnormality information (NO in S208), the syringe container 2 is attached to the syringe pump 3 (S111), and necessary piping and the like are performed. The display of the abnormality information is not limited to the above timing, and can be set according to the type of the abnormality information.

Hereinafter, the operation procedure in the ward 50 will be described with reference to FIG. 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 a switch of the pump device according to a predetermined procedure, or can be performed automatically by writing a check program in the storage means or the like. Further, when a nurse or the like performs a check operation, it is preferable to display an operation procedure or the like on a display device and store a confirmation signal or the like for normal operation in a storage means (memory).

The check items of the operation check include, for example, items necessary for determining whether or not the syringe pump operates normally, such as the mounting state of the syringe container, the operation check of each part, and the remaining battery level.

If normal operation cannot be confirmed by the above operation check (NO in S302), a warning is displayed (S303), and the operation of the syringe pump 3 is stopped (S304). After that, the syringe pump is replaced as needed.

After confirming that normal operation is performed by the operation check (YES in S302), for example, the display means 22 displays confirmation items as shown in FIG. 7 based on the information written in the IC tag 14 (YES in S302). S305). As shown in FIG. 7, if the patient information such as the patient name and the infusion information such as the infusion drug name are displayed and the instructions prepared by the doctor are followed, the confirmation buttons 23a and 23b are operated (YES in S306). This makes it possible to reliably confirm the patient's name and the like. 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, since the required confirmation items can be easily set and the confirmation input can be recorded, it is possible to set the confirmation items according to the patient and the type of infusion solution and perform a reliable confirmation operation. It becomes. In addition to the items to be confirmed, the display means 22 can be set so that the general prescription of the drug can be displayed as needed. In particular, in the present embodiment, the change information is displayed when the drug information is changed after the first drug information or the like is written in the IC tag of the syringe container. This makes it possible to reconfirm the drug and injection conditions. In addition, the change information is also sent to the equipment room, and if there is a difference in the information written in a plurality of departments, the operation of the device can be stopped until the information is confirmed / corrected.

In the present embodiment, the essential display item designation means 44 for adding the essential display item information among the written information is provided. The essential display item designating means 44 adds information for designating essential items in the server 6 or the like, and is provided by a program provided in the control signal generating means 30 of the syringe pump 3 or a program provided in the storage means 21. Controls the display of required display items with priority. For items other than the required items, a display information selection means that can be selectively displayed by a selection operation by a staff member or the like is provided. Therefore, when a nurse or the like has doubts about the operation of a drug or a syringe pump, it can be easily confirmed. Further, although it is possible that the items to be confirmed differ depending on the peculiarity of the infusion solution, in the present embodiment, it is possible to specify the essential items to be confirmed and display them on the display means 22 for confirmation.

In addition, conventionally, the content described in the instruction sheet is compared with the content described on the label of the syringe container and the patient information in the ward, but not only the label description but also the IC in the drug room is confirmed. Since the information written in the tag can be compared with the information described in the instruction sheet, the certainty is improved. Furthermore, even if there is change information, it is possible to easily confirm whether or not the change is reflected.

If the confirmation buttons 23a, 23b, 23c are not operated (NO in S306), a warning is displayed (S307), the confirmation items are displayed again (S305), and if the confirmation buttons 23a, 23b, 23c are not operated, the following It is set not to proceed to the step of.

After operating the confirmation buttons 23a, 23b, and 23c (YES in S306), the setting for infusion infusion described in the instruction sheet is made (S308). The above setting is performed by setting the infusion volume, the infusion rate, and the like, for example, as shown in FIG. Since the infusion volume and the infusion rate are written in the above IC tag in the drug room, the consistency between the written contents in the drug room and the input contents of the nurse or the like in the ward is automatically determined (S309). ). That is, if there is a discrepancy between the numerical value described in the instruction sheet and the set numerical value (NO in S309), a warning is issued (S310), and it is required to perform the injection setting again (S308). As a result, it is possible to effectively prevent an error in the infusion injection set value. In addition, if there is no consistency, it can be configured so that the doctor who created the instruction can be checked and the warning can be canceled if there is no problem. If there is the above change information, the above operation is performed based on the change information.

When the numerical values are consistent (YES in S309), the signal generation means 33 of the control signal generation means 30 generates a control signal for operating the drive control means 29 (S311). After that, the infusion permission display is displayed (S312), and the infusion solution is started by operating the start button (S313) (S314). The presence or absence of confirmation of the set numerical value and the confirmation item is output and stored in the storage means 21 or the IC tag 14 by the execution information output means 34 together with the execution information in the injection step performed thereafter (S315). Further, it can be configured so that the condition of the patient and the operation of the syringe pump device can be checked during the injection, the abnormality information can be detected, and a warning can be issued.

As shown in FIG. 12, after it is displayed that the predetermined injection process has been completed (S401), the completion is confirmed by the staff or the like confirming the disappearance of the infusion solution in the syringe container 2 (YES in S402). ). If the prescribed amount of infusion has not disappeared (NO in S402), there is a possibility that something is wrong with the syringe pump, etc., so confirmation work is performed (S404), and the remaining amount of injection, etc. is input from the input means. Then, it is recorded as abnormal information on an IC tag or the like. Even when the preset process is not performed, the injection can be forcibly terminated and the injection can be terminated. After completion, it is also possible to configure an item for checking whether the patient's condition is normal or to display an input screen for the remaining amount of the infusion solution on the display device to confirm that there is no abnormality. .. When confirming the end, it is desirable to configure the end time to be output to the IC tag 14 or the storage means 21. It is also possible to display a confirmation screen for confirming the patient's condition after the completion of injection and to record the patient's condition.

After confirming the end, the end time is recorded (S403), the syringe container 2 is removed from the syringe pump 3 (S406), the syringe container 2 is returned to the drug chamber, and the syringe pump is returned to the equipment room. In the drug room, the execution information and the like written in the IC tag 14 are taken out and stored in the server 6 (S408). In this case, it is checked again whether the information output by the execution information output means and the information written in the IC tag based on the instruction sheet, that is, the executed information and the information described in the instruction sheet are consistent. It is verified (S409) and a warning is issued if it is inconsistent (S410). For example, if for some reason the actual drug infusion volume or infusion rate data differs from the instructions, it is possible to investigate the cause based on the above data.

On the other hand, if there is no problem with the above data, the information is transferred to a medical record or the like and the information is accumulated, assuming that the treatment is performed as described in the instruction sheet prepared by the doctor (S411). As a result, the handling of the syringe container is completed and the syringe container is sent for disposal.

On the other hand, the syringe pump 3 is returned to the equipment room 5 (S421), and information is taken out from the storage means 21. If there is no problem with the above information, for example, if the operation as described in the instruction sheet is performed (YES in S423), the information in the storage means is accumulated in the server (S425), and the syringe pump The handling ends (S426). If an operation other than the normal operation is performed, for example, if the operation described in the IC tag or the operation different from the content input from the input means is executed (NO in S423), a warning is issued. It is issued (S424) and the cause is investigated. When the cause or the like is found, the content is recorded in the storage means 21 (S425), and the handling of the syringe pump ends (S426).

As described above, in the present embodiment, the consistency is verified by mutually comparing the content recorded on the IC tag 14, the content input to the syringe pump 3, the content described in the instruction sheet, and the like. .. Therefore, the safety of infusion injection is significantly improved.

FIG. 14 shows the functions of the server 6 provided in the drug room and the server 7 provided in the equipment room.

The server 6 installed in the drug chamber 6 includes an IC tag writing means 40 for writing predetermined information on the IC tag 14, an IC tag reading means 41 for reading the information written on the IC tag 14, and the IC. It is configured to include an information analysis means (artificial intelligence or the like) 42 that analyzes the information read by the tag reading means 41 and generates predetermined information.

Information is read from the IC tag 14 attached to the syringe pump after injection into the server 6 provided in the drug chamber. The above information is recorded in the patient's individual prescription database 54, and is used as reference information and consistency judgment information at the time of the next infusion infusion. For example, it can be configured to check for interactions with other prescribed therapeutic agents or for future infusions.

The infusion data of the infusion solution given to the patient has been recorded in the medical record or the like as the treatment data of the patient. The above data is used in various situations when treating patients, and is also important data in hospitals. On the other hand, even if an infusion infusion instruction is created, the details of the infusion operation actually performed are often not recorded, and it is sufficiently verified whether the infusion operation was performed according to the instruction. Not.

In the present embodiment, since the execution information is recorded in the IC tag 14 or the storage means 21, the injection work actually executed can be recorded in detail. In addition, the information analysis means 42 can easily verify whether or not the injection operation is performed according to the instruction sheet without any trouble. In addition, since verification can be performed automatically in a department other than the ward immediately after infusion, it is possible to perform verification with high accuracy without bothering nurses and pharmacists.

In addition, depending on the patient's condition, the type and amount of infusion may change immediately before the infusion operation, but since the execution information is recorded, it is possible to verify the circumstances when there is a change. It can be done easily.

Further, the information analysis means 42 according to the present 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.

As described above, the discriminating means 43 can determine the consistency between the information written in the drug maker and the information written in the drug room. As a result, it is possible to prevent the drug from being mixed up. In addition, since the consistency between the content of the instruction sheet and the general prescription of the drug can be determined, the content of the instruction sheet can be checked. Furthermore, it is possible to determine the consistency between the information described in the instruction sheet and the execution information, it is possible to verify the suitability of the operation and the drug after injection, and it is possible to quickly respond to any mistakes.

Further, as described above, the server 6 can write information that can be displayed on the display means 22 of the syringe pump 3 on the IC tag 14, and also adds essential display item information among the written information.
