In order to provide a thorough understanding of the present application, detailed structures will be presented in the following description in order to illustrate the technical solutions presented by the present application. Alternative embodiments of the application are described in detail below, however, the application may have other implementations in addition to these detailed descriptions.

As shown in fig. 1, an embodiment of the present invention provides an infusion pump 100 comprising a processor 110, a memory 120, and a drive device 130. Of course, the infusion pump may also include other components, such as a pump body, sensors, etc. The infusion pump 100 is used for drug infusion in conjunction with a tubing consumable or a syringe consumable such that fluid substances within the tubing consumable or syringe consumable are directionally delivered into a patient under the drive of the drive device 130 of the infusion pump. The infusion pump can comprise a syringe pump or an infusion pump, wherein when the infusion pump is a syringe pump, the corresponding consumable is a syringe consumable; when the infusion pump is an infusion pump, the corresponding consumable is an infusion tube consumable.

Taking a syringe pump as an example, the pump body has a mounting structure for mounting the syringe, for example, by fixing the syringe barrel of the syringe in a certain position by a clamping structure. The mounting structure includes, but is not limited to, a clamping structure, a magnetic attraction structure, a snap-fit structure, and the like. The driving device 130 is used to move the piston rod of the syringe to inject the liquid, for example, the piston rod of the syringe is pushed by the push rod to move. The driving device 130 may generally use a motor as a power element, and the motor converts the selective motion into linear motion through a transmission mechanism, so as to push a piston rod of the syringe to move and squeeze the liquid in the syringe. By setting the rotational speed of the motor, the rate of advancement of the motor to the associated syringe can be adjusted, thereby adjusting the dosage and rate of the drug administered. Of course, the driving device 130 may use a power member capable of outputting linear motion, such as an air cylinder, instead of the motor.

Alternatively, the infusion pump 100 may be implemented as an infusion pump for driving an infusion tube to effect infusion at a set time and flow rate. For infusion pumps, the pump body has a placement site for placing an infusion tube, and also has a liquid stopping structure for mounting the infusion tube and stopping the infusion tube during a non-working stage, for example, liquid in the infusion tube is placed by a liquid stopping clip to enter the human body in a large amount. The driving device 130 is used for driving the liquid in the infusion tube to flow. The driving device 130 may be a peristaltic pump or other devices capable of driving the liquid in the infusion tube.

The Processor 110 may be at least one of Application SPECIFIC INTEGRATED Circuit (ASIC), digital signal Processor (DIGITAL SIGNAL Processor, DSP), digital signal processing device (DIGITAL SIGNAL Processing Device, DSPD), programmable logic device (Programmable Logic Device, PLD), field programmable gate array (Field Programmable GATE ARRAY, FPGA), central processing unit (Central Processing Unit, CPU), graphics Processor (Graphics Processing Unit, GPU), controller, microcontroller, microprocessor, and the embodiments of the invention are not limited.

Memory 120 includes, but is not limited to, volatile memory and/or nonvolatile memory. Volatile memory can include, for example, random Access Memory (RAM) and/or cache memory (cache) and the like. The non-volatile memory may include, for example, flash memory and/or charged erasable programmable read-only memory, etc.

The drive means 130 are controlled by the processor 110. The processor 110 may be configured to send instructions to the driving device 130, so that the processor 110 may implement control of the driving device 130 according to the user's wishes.

In an embodiment of the present application, the processor 110 controls the drive means 130 to perform variable speed drug infusion to the patient. Variable speed drug infusion includes drug infusion based on time of day administration, i.e., drug infusion in a manner that the graphical form of the administration parameters is sinusoidal.

In embodiments of the present application, before infusion pump 100 is started for infusion, processor 110 first obtains administration parameters, including processor 110 obtaining administration parameters from a drug information repository 140 stored locally in memory 120, or processor 110 obtaining administration parameters remotely from hospital information platform 150.

In an embodiment of the present application, the memory 120 acts as a storage unit for the infusion pump 100 itself, which stores the drug information library 140 locally. The medication information base 140 includes a medication name and a medication administration parameter corresponding to the medication name, medication order information or medication interval time information, and a medication effective infusion time range. Before the infusion pump is started for infusion, the processor 110 obtains medication administration parameters corresponding to the medication name from the medication information repository 140 based on the medication name.

In an embodiment of the application, the processor 110 is communicatively connected to the hospital information platform 150, the hospital information platform 150 comprising a patient's treatment regimen and administration parameters corresponding to the patient's treatment regimen. Before the infusion pump is started for infusion, the processor 110 obtains medication administration parameters corresponding to the patient's treatment regimen from the hospital information platform 150 based on patient information.

In an embodiment of the present application, the hospital information platform 150 comprises at least one of a hospital system, a central station, a server. The processor 110 is communicatively coupled to the hospital information platform 150 via an external communication interface. The external communication interface may be one or a combination of local area network interfaces formed by Ethernet (Token Ring), token Bus (Token Bus) and backbone network Fiber Distributed Data Interface (FDDI) serving as the three networks, or one or a combination of wireless interfaces such as infrared, bluetooth, wifi, WMTS communication, or one or a combination of wired data connection interfaces such as RS232 and USB. The external communication interface can also be one or a combination of two of a wireless data transmission interface and a wired data transmission interface.

In an embodiment of the present application, the hospital information platform 150 further includes a storage device for storing the administration parameters of each infusion of the patient. Before the infusion pump is activated for infusion, the processor 110 obtains medication administration parameters for the last infusion with the patient from the hospital information platform 150 based on patient information.

In an embodiment of the application, the dosing parameter comprises at least a dosing time parameter comprising at least two of a start infusion time, a completion infusion time or a peak infusion time. Since drug infusion based on time of day administration may be patterned as a sinusoidal curve, the start infusion time, the completion infusion time, and the peak infusion time may be determined from at least two of the start infusion time, the completion infusion time, or the peak infusion time. For example, when it is determined that the start infusion time of the drug is 10:00 and the finish infusion time of the drug is 22:00 based on the time of day administration, then it may be determined that the peak infusion time of the drug is 16:00.

In an embodiment of the application, the dosing parameter further comprises at least one of total infusion, total infusion dose or peak flow rate. Since drug infusion based on time of day administration may be patterned as a sinusoidal curve, a flow rate or dose rate of drug at different infusion times may be obtained depending on at least one of total infusion, total infusion dose or peak flow rate, where the flow rate of drug may be expressed as a certain milliliter per hour (ml/h) and the dose rate of drug may be expressed as a certain milligrams per kilogram per hour (mg/kg/h) or a certain milligrams per square meter per hour (mg/m ²/h).

In an embodiment of the application, the infusion mode is automatically set based on the administration parameters, including a flow rate mode and a dose rate mode. For example, when the parameter is total infusion or peak flow rate, the infusion mode is automatically set to flow rate mode; when the dosing parameter is the total dose infused, the infusion mode is automatically set to the dose rate mode.

In embodiments of the present application, the dose rate mode may further comprise a body weight mode or a body surface area mode. In the body weight mode, the administration parameters include drug dosage rate (mg/kg/h), drug concentration, and patient body weight. In body surface area mode, the administration parameters include drug dosage rate (mg/m ²/h), drug concentration, and patient body surface area.

In embodiments of the present application, the infusion may be initiated after the dosing parameters are obtained and adjusted. For example, when a user selects a corresponding medication on infusion pump 100, processor 110 obtains medication parameters corresponding to the medication name from medication information base 140 based on the medication name, and may initiate infusion after appropriate adjustments to the medication parameters. When the processor 110 obtains the administration parameters corresponding to the patient's treatment plan from the hospital information platform 150 based on the patient information, the infusion may be started after the administration parameters are appropriately adjusted according to the order or the like in the treatment plan. It is also possible to combine the two, and after the processor 110 obtains the administration parameters corresponding to the drug name from the drug information base 140 based on the drug name, further adjusts the administration parameters according to the treatment plan obtained from the hospital information platform 150 for the patient, and then starts the infusion.

In embodiments of the present application, infusion may be initiated directly in accordance with the administration parameters after the administration parameters are obtained. For example, since most patient treatments are periodic, the administration parameters of each infusion of the patient are stored in the memory device of the hospital information platform 150, after the processor 110 obtains the administration parameters of the last infusion of the patient from the hospital information platform 150 based on the patient information, the infusion may be initiated directly according to the administration parameters.

In an embodiment of the present application, after the infusion is initiated, the processor 110 controls the drive device 130 to infuse at a variable rate according to the administration parameters. For example, drug infusion is performed in a manner such that the graphical form of the administration parameter is sinusoidal.

In an embodiment of the present application, after starting the infusion, if the time from the start of the infusion to the completion of the infusion exceeds the drug effective infusion time range, an alarm means (not shown) is used to issue an alarm message to prompt the start of the infusion to the completion of the infusion beyond the drug effective infusion time range. The alarm information includes, but is not limited to, an audible alarm, a flashing light alarm or a popup alarm, and may be represented by any form of text, graphics, or a combination of text and graphics, which is not limited in the embodiment of the present application.

In an embodiment of the application, the alarm means is adapted to issue an alarm message to indicate a medication order error when the medication order is wrong during a medication infusion. When the medication interval time is insufficient, the alarm device sends out alarm information to prompt that the medication interval time is insufficient.

In an embodiment of the present application, the processor 110 adjusts the flow rate after the infusion pump 100 is restarted when a pause occurs during drug infusion, while ensuring that the peak infusion time or completion infusion time is unchanged, and the total infusion volume or total infusion dose is unchanged.

In an embodiment of the present application, the infusion pump 100 is a single channel infusion pump, and when used for multi-drug infusion, the infusion pump 100 automatically stops infusion after the previous drug infusion is completed, and when the drug bag is replaced, the infusion pump is restarted for the infusion of the subsequent drug. When the medicine bag needs to be replaced, the alarm device can also send out alarm information to prompt the replacement of the medicine bag.

In an embodiment of the present application, the infusion pump 100 may also be a multi-channel infusion pump, and when used for multi-drug infusion, automatically closes the previous channel and opens the next channel after the previous drug infusion is completed, so as to infuse the next drug.

In an embodiment of the present application, infusion pump 100 performs variable speed infusion when single drug infusion is performed. When multi-drug infusions are performed, separate variable speed infusions may be performed for different drugs, or variable speed infusions may be performed for some of the drugs and constant speed infusions for others. For example, when A, B two drug infusions are required sequentially for a patient, drug a is first infused sinusoidally by time of day and then infused at a constant rate as is conventional when switching to drug B.

As shown in FIG. 2, an embodiment of the present invention provides an infusion pump 200 comprising a processor 110, a display system 220, and a drive device 230. Of course, the infusion pump may also include other components, such as a pump body, sensors, etc. The infusion pump 200 is used for drug infusion in conjunction with a tubing consumable or a syringe consumable such that fluid substances within the tubing consumable or syringe consumable are directionally delivered into a patient under the drive of the drive device 230 of the infusion pump. The infusion pump can comprise a syringe pump or an infusion pump, wherein when the infusion pump is a syringe pump, the corresponding consumable is a syringe consumable; when the infusion pump is an infusion pump, the corresponding consumable is an infusion tube consumable.

Taking a syringe pump as an example, the pump body has a mounting structure for mounting the syringe, for example, by fixing the syringe barrel of the syringe in a certain position by a clamping structure. The mounting structure includes, but is not limited to, a clamping structure, a magnetic attraction structure, a snap-fit structure, and the like. The driving device 230 is used to move the piston rod of the syringe to inject the liquid, for example, by pushing the piston rod of the syringe by a push rod. The driving device 230 may generally use a motor as a power member, and the motor converts the selective motion into linear motion through a transmission mechanism, so as to push a piston rod of the syringe to move and squeeze the liquid in the syringe. By setting the rotational speed of the motor, the rate of advancement of the motor to the associated syringe can be adjusted, thereby adjusting the dosage and rate of the drug administered. Of course, the driving device 230 may use a power member capable of outputting linear motion, such as an air cylinder, instead of the motor.

On the other hand, the infusion pump 200 may be implemented as an infusion pump for driving an infusion tube to perform infusion at a set time and flow rate. For infusion pumps, the pump body has a placement site for placing an infusion tube, and also has a liquid stopping structure for mounting the infusion tube and stopping the infusion tube during a non-working stage, for example, liquid in the infusion tube is placed by a liquid stopping clip to enter the human body in a large amount. The driving device 230 is used for driving the liquid in the infusion tube to flow. The driving device 230 may be a peristaltic pump or other devices capable of driving the liquid in the infusion tube.

The Processor 210 may be at least one of Application SPECIFIC INTEGRATED Circuit (ASIC), digital signal Processor (DIGITAL SIGNAL Processor, DSP), digital signal processing device (DIGITAL SIGNAL Processing Device, DSPD), programmable logic device (Programmable Logic Device, PLD), field programmable gate array (Field Programmable GATE ARRAY, FPGA), central processing unit (Central Processing Unit, CPU), graphics Processor (Graphics Processing Unit, GPU), controller, microcontroller, microprocessor, and the embodiments of the invention are not limited.

The display system 220 has a display screen capable of displaying information, wherein at least a partial area of the display screen is a touch display screen, which can be connected to the processor 210, and can both display information and receive a touch instruction from a user. Illustratively, the processor 210 outputs a touch screen drive signal to drive the touch screen and display screen image information to cause the display screen to display an image.

The display system 220 of the infusion pump 200 is used to graphically display the administration parameters at a graphical interface. Providing a plurality of visual interfaces after the infusion pump 200 is turned on to before the infusion pump 200 is turned off, displays in a display screen of the infusion pump 200, and presents the progress of the current infusion.

The drive means 230 is controlled by the processor 210. The processor 110 may be configured to send instructions to the driving device 230 to cause the processor 210 to implement control of the driving device 230 at the discretion of the user.

Fig. 3 shows a preview interface displayed before infusion pump 200 is started for infusion, fig. 4 shows a preview waiting interface displayed after infusion pump 200 is started for infusion, and fig. 5A and 5B show infusion interfaces displayed during drug infusion of infusion pump 200.

In the preview interface of fig. 3, the drug name, mode of administration, and parameters of administration are included. The drug name options can be classified according to the type of the drug to improve the speed of searching the target drug by the user, and the drug classification can comprise common drugs, sedative drugs, analgesic drugs, anesthetic drugs and the like. The administration modes include a time of day administration mode and a normal mode (i.e., a constant speed administration mode). In an embodiment of the present application, the processor 210 controls the drive means 230 to perform variable speed drug infusion to the patient, including drug infusion based on time of day administration, thus appearing as "sine time of day administration" in the preview interface.

In embodiments of the present application, before infusion pump 200 is started for infusion, processor 210 first obtains administration parameters, including processor 210 obtaining administration parameters from a drug information repository stored locally in memory, or processor 210 obtaining administration parameters remotely from a hospital information platform.

In an embodiment of the application, the dosing parameter comprises at least a dosing time parameter comprising at least two of a start infusion time, a completion infusion time or a peak infusion time. Since drug infusion based on time of day administration may be patterned as a sinusoidal curve, the start infusion time, the completion infusion time, and the peak infusion time may be determined from at least two of the start infusion time, the completion infusion time, or the peak infusion time. In the preview interface of fig. 3, the beginning infusion time of the drug is shown to be 10:00 today, the completion infusion time of the drug is shown to be 22:00 today,

In an embodiment of the application, the dosing parameter further comprises at least one of total infusion, total infusion dose, peak flow rate or peak dose rate.

In the preview interface of fig. 3, the total infusion of drug is shown to be 300ml.

In fig. 4, 5A and 5B, the dosing parameter is graphically displayed as a sinusoidal curve with time as the abscissa showing at least two of a start infusion time, a completion infusion time, or a peak infusion time, with a flow rate or a dose rate as the ordinate showing a peak flow rate or a peak dose rate.

In an embodiment of the present application, the preview interface of fig. 3 further includes a start button and a push button, and when the start button is pressed, the graphical interface switches to the preview waiting interface shown in fig. 4. The preview waiting interface includes a drug name, a start countdown, and a patterned sinusoidal drug delivery parameter, which in the example shown in fig. 4 includes a start infusion time, a finish infusion time, and a peak infusion time, and which also includes a peak flow rate.

In an embodiment of the present application, infusion modes are automatically set based on administration parameters, including a flow rate mode (as shown in fig. 5A) and a dose rate mode (as shown in fig. 5B). For example, when the parameter is total infusion or peak flow rate, the infusion mode is automatically set to flow rate mode; when the dosing parameter is the total dose infused, the infusion mode is automatically set to the dose rate mode.

In the infusion interface of fig. 5A, including drug name and administration parameters patterned into a sinusoid in a flow rate mode, the administration parameters patterned into a sinusoid include start infusion time, completion infusion time, and current flow rate.

Fig. 6 shows a flow chart of a method 600 of operating an infusion pump according to an embodiment of the present application.

As shown in fig. 6, the operation method 600 of the infusion pump is applied to the infusion pump, and may include the following steps:

step S601: obtaining administration parameters from a locally stored drug information library or remotely from a hospital information platform, wherein the administration parameters comprise administration time parameters;

Step S602: infusion is initiated and variable speed drug infusion is performed to the patient based on the dosing parameters.

In an embodiment of the present application, the administration parameters are first obtained before the infusion pump is started for infusion in step S601, including obtaining the administration parameters from a locally stored drug information repository or remotely from a hospital information platform.

In an embodiment of the present application, the acquiring the drug administration parameter from the locally stored drug information base includes acquiring the drug administration parameter corresponding to the drug name from a drug information base storing the drug name and the drug administration parameter corresponding to the drug name, the medication order information or the medication interval time information, and the drug effective infusion time range based on the drug name; the remotely acquiring the administration parameters from the hospital information platform comprises acquiring the administration parameters corresponding to the treatment plan of the patient from the hospital information platform storing the treatment plan of the patient and the administration parameters corresponding to the treatment plan of the patient based on the patient information; the remotely acquiring the administration parameters from the hospital information platform further comprises acquiring the administration parameters of the last infusion of the patient from the hospital information platform storing the administration parameters of each infusion of the patient.

In embodiments of the present application, the infusion may be initiated after the dosing parameters are obtained and adjusted. For example, when a user selects a corresponding drug and obtains a drug administration parameter corresponding to the drug name from a drug information base based on the drug name, infusion may be started after appropriate adjustment of the drug administration parameter. Or infusion may be initiated directly in accordance with the dosing parameters after they are obtained. For example, since most patient treatments are periodic, infusion may be initiated directly in accordance with the administration parameters after the administration parameters for the last infusion with the patient are obtained from the hospital information platform based on patient information.

In an embodiment of the application, step S602, a variable rate drug infusion is performed to the patient based on the administration parameters. In particular, the variable rate drug infusion is performed displaying a graphical form of the dosing parameter, wherein the graphical form of the dosing parameter is sinusoidal.

In an embodiment of the application, the dosing parameter comprises at least a dosing time parameter comprising at least two of a start infusion time, a completion infusion time or a peak infusion time. The sinusoid is on a time-by-time axis that displays at least two of a start infusion time, a completion infusion time, or a peak infusion time. Since the graphical form of the dosing parameter is sinusoidal, the start infusion time, the completion infusion time, and the peak infusion time may then be determined from at least two of the start infusion time, the completion infusion time, or the peak infusion time.

In an embodiment of the application, the dosing parameter further comprises at least one of total infusion, total infusion dose or peak flow rate. The sinusoid has a flow rate or dose velocity as an ordinate, which shows a peak flow rate or peak dose velocity. Since the graphical form of the dosing parameter is sinusoidal, a flow rate or dose rate of the drug at different infusion times may be obtained depending on at least one of the total infusion, the total infusion dose or the peak flow rate, wherein the flow rate of the drug may be expressed as a certain milliliter per hour (ml/h) and the dose rate of the drug may be expressed as a certain milligrams per kilogram per hour (mg/kg/h) or a certain milligrams per square meter per hour (mg/m ²/h).

In an embodiment of the present application, in the infusion interface, including drug name and administration parameters patterned into a sinusoid in a flow rate mode, the administration parameters patterned into a sinusoid include start infusion time, completion infusion time, and current flow rate (or current dose rate). The current infusion schedule is also shown in the infusion interface, with the coverage area to the left of the sinusoidal curve representing the infused volume, and the infused volume (or infused dose) and total infused volume (or total infused dose) also indicated in numerical form.

In embodiments of the present application, when a pause occurs during drug infusion, after a restart, the flow rate is adjusted to ensure that the peak infusion time or completion infusion time is unchanged, and the total infusion volume or total infusion dose is unchanged, the displayed sinusoidal curve is changed.

In an embodiment of the present application, after starting the infusion, if the start-infusion time to the completion-infusion time exceeds the drug effective-infusion time range, an alarm message is sent to prompt the start-infusion time to the completion-infusion time to exceed the drug effective-infusion time range. The alarm information includes, but is not limited to, an audible alarm, a flashing light alarm or a popup alarm, and may be represented by any form of text, graphics, or a combination of text and graphics, which is not limited in the embodiment of the present application.

In an embodiment of the present application, during drug infusion, when the medication order is incorrect, an alert is sent to indicate that the medication order is incorrect. When the medication interval time is insufficient, an alarm message is sent out to prompt that the medication interval time is insufficient.

In an embodiment of the application, when the single channel infusion pump is used for multi-drug infusion, the infusion is automatically stopped after the previous drug infusion is completed, and an alarm message is sent to prompt the replacement of the drug bag, and when the drug bag is replaced, the infusion of the next drug is started again.

In an embodiment of the present application, when the multi-channel infusion pump is used for multi-drug infusion, the previous channel is automatically closed and the next channel is opened after the previous drug infusion is completed, so that the infusion of the next drug is performed.

The working method of the infusion pump provided by the embodiment of the invention can realize biological rhythm administration in a real sense, and provides a concise and easy-to-use infusion mode for clinic.
