The invention claims priority of Chinese Patent Application No. 202311253090.0, entitled “Infusion Control Method, Device and Storage Medium” filed with the China National Intellectual Property Administration on Sep. 22, 2023, which is incorporated herein by reference in its entirety.
This invention generally relates to the field of medical technologies, and more particularly, to an infusion control method, device and corresponding computer-executable code stored in a storage medium.
With the development of medical technology, infusion devices with higher accuracy and safety have been widely used. These typically use a mechanical driving force to accurately control the number of drops and flow rate of infusion to ensure that the medication can accurately and safely enter the patient's body.
However, the volume of medication that can be infused by the infusion device at any one time is always limited. In the treatment of critically ill patients, there is usually a need for continuous and long-term infusion, which inevitably leads to situations where medication or pumps need to be replaced. During the process of replacing medications or pumps, fluctuations in the infusion rate are inevitable. Significant fluctuations in the infusion rate can affect the patient's vital signs, and even endanger the patient's life in severe cases.

The accompanying drawings herein, which are incorporated into and form a part of the specification, illustrate embodiments consistent with the invention and are used in conjunction with the specification to explain the principles of this invention.
By means of the above accompanying drawings, definite embodiments of the invention have been shown, which will be described in greater detail later. These accompanying drawings and textual descriptions are not intended to limit the scope of the invention idea by any means, but rather to illustrate the concepts of the invention for those skilled in the art by reference to particular embodiments.
Example embodiments will be described herein in detail and are illustrated in the accompanying drawings. When the following description relates to the accompanying drawings, the same numerals in the different accompanying drawings indicate the same or similar elements unless otherwise indicated. The embodiments described in the following example embodiments do not represent all embodiments consistent with the invention. Rather, they are only examples of devices and methods consistent with some aspects of this invention as detailed in the appended claims.
The terms “first”, “second”, “third”, “fourth” and the like, if any, in the specification and claims of the present application and the accompanying drawings described above are used to distinguish similar objects and need not be used to describe a particular order or sequence. It should be understood that the data so used may be interchangeable, where appropriate, so that the embodiments of the present invention described herein can, for example, be practiced in an order other than those illustrated or described herein. In addition, the terms “include” and “have”, and any variations thereof, are intended to cover non-exclusive embodiments, e.g., processes, methods, systems, products or devices that include a series of steps or units need not be limited to those clearly listed, but may include other steps or units that are not clearly listed or that are inherent to those processes, methods, products or devices.
Critically ill patients require the use of vasoactive agents to improve blood pressure, cardiac output, and microcirculation due to the presence of hemodynamic instability during treatment. Vasoactive agents are medications that are used to combat shock by modulating vasodilatation, altering vascular function, and improving microcirculatory perfusion, and are commonly used, such as dopamine, sodium nitroprusside, and epinephrine. Some intensive care patients often need to use vasoactive medications continuously. However, in the process of changing medications and pumps, there are bound to be flow rate fluctuations, which will affect the patient's vital functions and even endanger their lives. How to minimize flow rate changes due to medication and pump changes to ensure that the flow rate is stable during the continuous use of vasoactive medications in patients and thus improve infusion safety is a current problem to be solved.
In order to solve the above problem, the invention provides an infusion control method, in which the rise time required for the second infusion device to reach a target infusion rate from initiating the infusion is pre-calculated, and a pre-start message is sent to the second infusion device at least as far in advance of the end of the first infusion as the rise time, so as to enable the second infusion device to reach the target infusion rate, which is preferably the same as or close to the ongoing infusion rate of the first infusion device, before the end of the infusion of the first infusion device. The second infusion device thus infuses the patient at the target infusion rate after the end of infusion of the first infusion device. In this way, the infusion flow rate does not change too much when changing pumps or medications, and the flow rate remains stable, which can reduce the safety hazard caused by the change of flow rate due to the change of medications or pumps, and thus improve the safety of the infusion.
The technical solution of the invention and how it solves the above technical problems are described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in certain embodiments. Embodiments of the invention will be described below in conjunction with the accompanying drawings.
In addition, the infusion system also includes a second infusion device. The first infusion device and the second infusion device involved in the invention may be an infusion pump, a syringe pump, or the like, for controlling the infusion process parameters such as the flow rate of a medicament. The first infusion device and the second infusion device are connected by wired and/or wireless means to transmit information to each other so as to realize steady-state infusion based on the method of the invention.
For example, the first infusion device and the second infusion device may be connected wired through network cable, coaxial cable, fiber optics, etc., for inter-transmission of data. A communication link between the first infusion device and the second infusion device may also be established via wireless technology such as WiFi, 4G, 5G, Bluetooth, and Zigbee, to provide a basis for data communication between the first infusion device and the second infusion device. A combination of one or more of these may be selected to realize the connection in practical applications to better realize the steady-state infusion. In one embodiment, the first infusion device and the second infusion device may also be plugged into an infusion workstation to realize a wired connection.
When there are n (n≥2) infusion devices involved for continuous steady-state infusion, the infusion control device of the embodiment may also be disposed on the preceding (n−1) infusion devices, thereby realizing continuous steady-state infusion of multiple infusion devices.
As an example, the embodiment of the invention is illustrated with the implementing system being the infusion control device. As shown in
As an example, steady-state infusion may involve a plurality of infusion devices for continuous infusion, including at least a first infusion device and a second infusion device. The first infusion device refers generically to an infusion device that is infusing or is about to start infusion, and the second infusion device refers generically to the next infusion device after the first infusion device. The purpose of the steady-state infusion is to control the flow rate of the medicament solution to be stable during the entire infusion process. This avoids too great a fluctuation in the flow rate, which may affect vital functions of the patient or even endanger the life of the patient. In the invention, the infusion control device needs to first obtain a rise time of the second infusion device. The rise time is the time required for the second infusion device to reach the target infusion rate from initiating infusion. It should be noted that the “initiating infusion” herein is not the actual initiation of infusing the patient, but is only a pre-initiation of the infusion operation, so that the infusion device reaches the target infusion rate before infusing the patient. The rise time is related to one or more of a drive parameter of the second infusion device, a specification parameter of a syringe connected to the second infusion device, and a target infusion rate.
As an example, the drive parameter of the second infusion device may be an intrinsic parameter related to its ability to drive the flow of the medicament. This may, for example, be related to a driving distance parameter of the infusion device, such as a transmission gap or a push head gap, but also related to a driving force parameter of the infusion device, such as a driving force, a driving power, and a stiffness of the infusion device. Because of machining errors, the drive parameters of each infusion device will have some differences, which can be obtained through testing and calibration before leaving the factory. The specification parameter of the syringe may include parameters such as the diameter, length, and capacity of the syringe, or may be a comprehensive parameter obtained by determining the above-mentioned parameters.
In one example, the rise time may be obtained according to the following calculation formula:
t0 is the rise time, M may be the drive parameter of the second infusion device in mm, v may be a target infusion rate of the second infusion device in ml/h, A is a parameter determined for the specific syringe in mm/h, which may be obtained by dividing the length of the syringe by the capacity. K is a calibration coefficient which may be determined by per-device testing or other experimental means and which is negatively correlated with the speed of the moving pusher (piston/plunger/etc.) head up the infusion device. The smaller the speed, the larger K. The calibration coefficient K is generally greater than or equal to 1, which is not limited in this invention. Accordingly, the unit of the calculated rise time t0 is h, which may be converted to other units according to practical needs, for example, to minutes and the like.
Therein, the rise time of the second infusion device may be calculated by any medical device in the infusion delivery system, and then shared to other medical devices that need to use the data, which is not limited in the invention. In practice, the rise time may be obtained by the device for calculating the rise time after obtaining each parameter in the formula (1) and bringing it into the formula.
As an example, the respective parameters of the above formula may be obtained by evaluating different parameter settings for the respective infusion device while it performs steady-state infusion prior to actual infusion of a patient. Setting the parameters may be done by the user inputting them directly, or the corresponding values of some parameters may be pre-set, and the corresponding parameter values may be applied after being selected by the user. For example, parameters such as a medication name, a medication concentration, a target infusion rate, a flow rate, and a preset volume may be input/selected, and may also be selected and applied after information such as the brand, model, and specification of the infusion device is input/selected to obtain the corresponding drive parameters of the second infusion device, which is not limited in the invention.
In some examples, some or all of the infusion parameters of the plurality of infusion devices performing the steady-state infusion are the same. In order to save time for parameter setting and also to improve the user experience, the infusion control method of the invention may further include sending the infusion parameter information of the first infusion device to the second infusion device.
As an example, before actual infusion, the plurality of infusion devices for performing steady-state infusion and their respective infusion parameters may be set, such as the medication name, the medication concentration, the target infusion rate, the flow rate, and the preset volume. If same-medication infusion is used or the infusion parameters of each infusion device are the same, the infusion parameters of each infusion device may be designed to be able to be synchronized with one key, and the parameters that have been set up can be synchronized to other infusion devices. For example, if the infusion parameter information of the first infusion device is the same as the infusion parameter information of the second infusion device, after the infusion parameter information of the first infusion device has been set, the infusion parameter information of the first infusion device can be sent directly to the second infusion device to save time in setting the parameters.
As an example,
As an example,
As an example, in order to realize steady-state infusion using the method of embodiments of this invention, the infusion control device also signals the second infusion device to prepare to be at its infusion rate before the end of the infusion of the first infusion device. Thus, the infusion end time of the first infusion device also needs to be determined.
As an example, the step of determining the infusion end time of the first infusion device may include obtaining an infusion state of the first infusion device, and determining the infusion end time of the first infusion device based on the infusion state.
As an example, the infusion state of the first infusion device may be monitored, and based on the specifics of the infusion state, information such as the actual remaining volume of infusion, and the actual infusion rate of the first infusion device may be obtained, and then the infusion end time may be determined based on such information.
As an example, after determining the rise time of the second infusion device and the infusion end time of the first infusion device, the infusion control device outputs the pre-start message to the second infusion device at least as far in advance of the infusion end time as the rise time. The pre-start message is configured to instruct the second infusion device to pre-start so that the second infusion device reaches a target infusion rate before the first infusion device ends the infusion and the second infusion device can take over supplying medication to the patient upon switch-over from the first infusion device.
For example, if it is determined that the rise time required for the second infusion device to reach the target infusion rate from initiating the infusion is 10 min, the pre-start message should be sent to the second infusion device at least 10 min prior to the end of the infusion of the first infusion device, so that the second infusion device can increase its output rate to the target infusion rate. Following this, after the end of the infusion of the first infusion device, the second infusion device may directly start the infusion at the target infusion rate. This thus avoids large flow rate fluctuations in the process of convergence of the infusion devices in order to provide continuous uninterrupted infusion at a desired, more stable infusion rate in continuous infusion, reducing the probability of large changes in the patient's vital functions and improving the safety of the infusion.
As an example, if the infusion control device is used to command the first infusion device, in the step of outputting the pre-start message to the second infusion device, the pre-start message may be sent directly from the first infusion device to the second infusion device, or the pre-start message may be sent by the first infusion device to the infusion workstation/infusion central station first, and then be forwarded by the infusion workstation/infusion central station to the second infusion device. If the infusion control device is configured to cooperate with the infusion workstation/infusion central station, the infusion workstation/infusion central station may send the pre-start message to the second infusion device after determining the rise time of the second infusion device and the infusion end time of the first infusion device, and before the rise time from the infusion end time of the first infusion device.
Regardless of the manner in which the pre-start message is sent as described above, it is only necessary for the second infusion device to receive the pre-start message long enough before the end of the infusion of the first infusion device for it to get its output rate up to the target infusion rate in advance.
The infusion control method provided embodiments of the invention, include: obtaining a rise time of the second infusion device, in which the rise time is a time required by the second infusion device from initiating infusion to reaching the target infusion rate; determining an infusion end time of the first infusion device; and outputting the pre-starting message to the second infusion device at least as far in advance of the end time of the infusion as the rise time. The infusion control device sends the pre-start message to the second infusion device at least as far in advance of the end time of the infusion of the first infusion device as the rise time to instruct the second infusion device to increase its output rate to reach the target infusion rate before the end time of the infusion of the first infusion device, so that the second infusion device can start the infusion at the target infusion rate directly after the infusion end time of the first infusion device. This thus avoids large flow rate fluctuations in the process of convergence of the infusion devices in order to provide continuous, uninterrupted infusion at a desired, more stable infusion rate thereby reducing the probability of large changes in the patient's vital signs and improving the safety of the infusion.
In some examples, if the infusion control device used together with an infusion workstation/infusion central station, and the infusion control is performed by the infusion workstation/infusion central station, after outputting the pre-start message to the second infusion device, the infusion control method of the invention may further include the following steps:
An up-to-standard message is issued when the actual infusion rate of the second infusion device reaches a target infusion rate. A failure alarm is output when the central station detects that the first infusion device has not received the up-to-standard message from the second infusion device within a preset time before an end of the infusion of the first infusion device.
As an example, the infusion workstation/infusion central station and the like may also be configured to monitor the infusion states of the first infusion device and the second infusion device, and to issue the up-to-standard message when the actual infusion rate of the second infusion device reaches the target infusion rate, so as to prompt the first infusion device or the relevant person that the actual infusion rate of the second infusion device has reached the target infusion rate, and that the switching of equipment can be carried out. In addition, the workstation/infusion central station may determine whether the first infusion device receives the up-to-standard message from the second infusion device within a preset time before the end of the infusion. If the central station confirms that the first infusion device received the up-to-standard message of the second infusion device within the preset time before the end of the infusion, the normal operation of the respective devices is continued, or an explicit prompt characterizing that the up-to-standard message of the second infusion device has been received is issued. And if it is determined that the first infusion device has not received the up-to-standard message of the second infusion device within the preset time before the end of the infusion, the failure alarm is output to prompt the user to carry out abnormality processing as soon as possible.
The invention does presuppose or require any specific value of the preset time. For example, the preset time may be set to a value greater than or equal to 0 according to practical demand. When the preset time is 0, that is, when the first infusion device is just at the end of the infusion, the failure alarm may be issued when the up-to-standard message from the second infusion device is not yet received at the end of the infusion of the first infusion device, so as to allow more time for pre-starting for the second infusion device, so that it reaches the target flow rate of the infusion as closely as possible before the start of the second device's infusion. More preferably, to allow time for the user to deal with an abnormal situation, the preset time is set to 30 s or 1 min or some other smaller value greater than 0, which can allow time for the user to carry out processing of the fault without causing too great an impact on the infusion result.
In addition, self-monitoring may be performed by the first infusion device, and if the up-to-standard message from the second infusion device is not received within the preset time before the end of the infusion, the failure alarm is output.
The specific implementation of steps S301-S303 is similar to steps S101-S103, and will therefore not be repeated here.
As an example, if the first infusion device and the second infusion device are continuously operating, the infusion workstation/infusion central station may also control the second infusion device to continue the infusion at the target infusion rate when it is determined that the second infusion device has reached the target infusion rate and the first infusion device has finished its phase of the infusion.
The target infusion rate of the first infusion device and the target infusion rate of the second infusion device may be the same or different. If they are the same, the entire infusion process may be realized to be infused at a stable flow rate, thereby improving the safety of the infusion. If they are different, the difference in the flow rate fluctuation caused by switching the infusion device may also be reduced, and a relatively stable output process may also be realized, thereby improving the safety of the infusion.
The infusion control method provided by an embodiment of the invention includes: obtaining a rise time of the second infusion device, in which the rise time is the time required for the second infusion device to reach a target infusion rate from when it initiates infusion; determining an infusion end time of the first infusion device; outputting a pre-start message to the second infusion device at least before the rise time from the infusion end time; and controlling the second infusion device to perform the infusion when the second infusion device reaches the target infusion rate and the first infusion device ends the infusion. The infusion control method of the invention can automatically control the second infusion device to start the infusion at the target infusion rate after the first infusion device has finished its phase of the infusion. This avoids large flow rate fluctuations in the process of convergence of the infusion devices in order to provide continuous, uninterrupted infusion at a desired, more stable infusion rate, reducing the probability of large changes in the patient's vital signs and improving the safety of the infusion.
When there are n (n≥2) infusion devices involved in the continuous steady-state infusion, the infusion control method provided in this embodiment may also be applied to other subsequent infusion devices other than the first infusion device, so as to realize continuous steady-state infusion provided by multiple infusion devices.
As shown in
As an example, the second infusion device first obtains its own target infusion rate, which may be obtained by the user when performing parameter setting. If it is the same as the target infusion rate of the first infusion device, it may also be acquired by the first infusion device when performing information synchronization, although this is not required by the invention.
As an example, the second infusion device may determine the rise time for reaching the target infusion rate based on the target infusion rate and the predetermined calculation rule after acquiring its target infusion rate.
The rise time is a function of one or more of: a drive parameter of the second infusion device, a specification parameter of a syringe connected to the second infusion device, and the target infusion rate.
As an example, the drive parameter of the second infusion device, which may be an intrinsic parameter of the infusion device, to drive the flow of the medicament, may be related not only to a driving distance parameter of the infusion device, such as a transmission gap, a push head gap, but also to a driving force parameter of the infusion device, such as a driving force, driving power, and a stiffness of the infusion device. Because of machining errors, the drive parameters of each infusion device will have some differences, which can be determined through testing and calibration before leaving the factory. The specification parameter of the syringe may include parameters such as the diameter, length, and capacity of the syringe, or may be a comprehensive parameter obtained by determining the above-mentioned parameters.
As an example, the predetermined calculation rule may be chosen according to predetermined calculation formula, and the predetermined calculation formula may be formula (1) above, the specific realization of which has been described in the foregoing embodiments and will not be repeated herein.
As an example, when the second infusion device determines the rise time, the rise time is also output to the first infusion device. Given the rise time sent by the second infusion device, the first infusion device can determine the length of time required by the second infusion device from initiating its phase of infusion to reaching the target infusion rate, thereby determining when to send the pre-start message to the second infusion device.
The first infusion device and the second infusion device may be connected by wired and/or wireless means. For example, the second infusion device may directly output the rise time to the first infusion device, or may first send the rise time to the infusion workstation/infusion central station, which then forwards it to the first infusion device.
In some examples, the infusion control method provided by the embodiment, further includes performing a pre-start based on a received pre-start message.
As an example, the pre-start message may be issued prior to the rise time from an infusion end time of the first infusion device, and the second infusion device may perform a pre-start procedure after receiving the pre-start message, to enable the second infusion device to reach the target infusion rate before the end of infusion of the first infusion device.
In some examples, the infusion control method provided in this embodiment, further includes outputting an up-to-standard message when an actual infusion rate reaches the target infusion rate.
As an example, when the actual infusion rate reaches the target infusion rate, the second infusion device may also output the up-to-standard message to prompt the first infusion device or a relevant person that the actual infusion rate of the second infusion device has reached the target infusion rate, and that device switching can be performed.
The embodiment provides an infusion control method applied to a second infusion device in an infusion system, in which the infusion system includes a first infusion device and the second infusion device. The method includes: obtaining a target infusion rate; determining a rise time to reach the target infusion rate based on the target infusion rate and a predetermined calculation rule; and outputting the rise time to the first infusion device. As a result, the first infusion device may determine the length of time required by the second infusion device from initiating the infusion to reaching the target infusion rate based on the rise time sent by the second infusion device, thereby determining the time for sending the pre-initiation message to the second infusion device, so as to ensure that the second infusion device may reach the target infusion rate before the end of the infusion of the first infusion device. Accordingly, after the end of infusion by the first infusion device, when infusion is switched to the second infusion device, the second infusion device is able to directly start infusing at the target infusion rate. This avoids large flow rate fluctuations in the process of convergence of the infusion devices in order to provide continuous, uninterrupted infusion at a desired, more stable infusion rate, reducing the probability of large changes in the patient's vital functions and improving the safety of the infusion.
In addition, in various electronic medical devices such as the first infusion device, the second infusion device, the infusion workstation, the infusion central station, and the like involved in the invention for performing the steady-state infusion control, each device may also include a display screen, and the infusion control method of the invention may also include displaying infusion information in a display screen; wherein the infusion information comprises one or more of: an infusion trend graph, an infusion sequence information, an infusion state information, an infusion end time, and the rise time.
As an example, the infusion trend graph may depict a trend of change in the actual infusion rate with the infusion time; infusion sequence information may indicates an infusion sequence of each of the infusion devices; and infusion status information may indicate an infusion state of each of the infusion devices.
As an example,
In addition, the infusion trend line A and the infusion trend line B may be shown as using the same coordinate system, as shown in
As another example,
In addition, basic information such as network connection information, current time information, remaining power information, patient bed number, and infusion end time may be displayed in the interface 600. The infusion end time may be determined by the current time information as well as the remaining time of the infusion. Controls such as fast-forward and pause may optionally be provided in the interface 600 for the user to carry out the control. When the “Steady State 1” icon 11 is not displayed or is displayed as “none”, this may indicate that there is no other device that needs to continue to perform the infusion after the first infusion device has finished the infusion.
As an example,
As an example,
After finishing the pre-start procedure and entering the waiting state, however, the volume already output by the second device may have been, for example, 01.50 ml, the remaining volume may be 48.50 ml, the remaining time becomes 04:51:00 and the infusion rate becomes the target infusion rate of 10.0 ml/h. Based on the volume of the change in the remaining time, the rise time can be determined to be 10 min, which may also be displayed in the interface; this is not a limitation of the invention, however.
As an example,
In some examples, an infusion trend graph may also be displayed in the display interface. As an example,
