By means of the above accompanying drawings, definite embodiments of the invention are shown and will be described in more detail later. These accompanying drawings and textual descriptions are not intended to limit the scope of the presently conceived disclosure in any way, but rather to illustrate the concepts of the invention for those skilled in the art by reference to particular embodiments.
Example of embodiments will be described herein in detail, which are represented 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 the invention as detailed in the appended claims.
As the medical industry evolves, medical devices are becoming more intelligent. For example, infusion devices can be automated to administer an infusion to a patient.
The inventors of this invention have found that, during the process of drug infusion, healthcare personnel set infusion parameters of the infusion device according to their own experience, thereby causing the infusion device to infuse the patient according to the set infusion parameter. When the physiological parameters of the patient reach the expectations of the healthcare personnel, the healthcare personnel will then switch the infusion device to other modes, so as to facilitate the infusion device to set the infusion parameters in line with the current state of the patient. This involves a manual operation for the mode switching of the infusion parameters in the infusion device, and this manual operation takes a long time, resulting in a low operation efficiency of the infusion device.
The inventors therefore thought that the infusion device, when detecting that the physiological parameters of the target object exceed a preset range of physiological parameters, can automatically adjust the infusion parameters of the infusion device by means of the physiological parameters, the body weight of the target object, or a constant infusion parameter, so that there is no need for healthcare personnel to manually switch the operating mode of the infusion device for adjusting the infusion parameters, thereby improving the operation efficiency of the infusion device.
The invention provides a control method of an infusion device. As shown in
The technical solution of the invention and how the technical solution of the invention solves the above-described technical problems are described in detail in the following description of specific embodiments. These 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.
As shown in
Step S201, the target object is infused according to the set infusion parameter, and a current first physiological parameter of the target object is acquired.
In this embodiment, the execution subject is an infusion device, and the infusion device may be a device that performs infusion for the human body. For example, the infusion device may be an infusion pump.
When the infusion device performs the infusion on the target object, it first infuses the target object according to the set infusion parameter. The set infusion parameter may be entered by healthcare personnel on the infusion device in advance. The target object refers to an object to be infused by the infusion device, and the target object may be a patient.
In an embodiment, the infusion device is provided with a display screen, and the infusion device outputs a displayed control page on which the healthcare personnel may enter the infusion parameters. The infusion device, when detecting a completion operation of the infusion parameters triggered on the control page, obtains the input infusion parameters according to the completion operation and determines the set infusion parameters according to the input infusion parameters. The completion operation may be a click operation of a confirmation button on the control page, i.e., the healthcare practitioner clicks the confirmation button after inputting the infusion parameters on the control page, and the infusion device detects the completion operation.
In another embodiment, the infusion device may be communicatively connected to the control device, and the healthcare personnel may input the infusion parameters to the infusion device via the control device, i.e., the control device transmits the infusion parameters input by the healthcare personnel as well as an identification of the healthcare personnel to the infusion device, and the infusion device determines, according to the identification, whether or not the healthcare personnel has the setting privilege. If it is determined that the healthcare personnel has the setting privilege, the infusion device then takes the infusion parameters as the set infusion parameters. The control device may be a device loaded with a control program for the infusion device. For example, the control device may be a portable terminal of the healthcare personnel; or, the control device may be a computer.
When infusing the target object according to the set infusion parameter, the infusion device also obtains a current physiological parameter of the target object in real time or at regular intervals, and the current physiological parameter is defined as a first physiological parameter. The first physiological parameter is related to the drug infused by the infusion device. For example, the drug infused by the infusion device is an anesthetic, then the first physiological parameter is a Bispectral index (BIS, brain electric dual frequency index) of the target object. The set infusion parameters includes the set infusion concentration, the set infusion volume, and the set infusion time. The infusion device is communicatively connected to the acquisition device for the physiological parameters, and the infusion device sends an acquisition request for the physiological parameters to the acquisition device when it needs to acquire the physiological parameters, and the acquisition device, upon receiving the acquisition request, sends the current first physiological parameter of the target object to the infusion device, i.e., the infusion device receives the current first physiological parameter of the target object sent by the acquisition device.
Step S202, when the first physiological parameter falls outside of a preset range of physiological parameters, a target infusion parameter is determined according to the target parameter, and the target object is infused according to the target infusion parameter. The target parameter includes the first physiological parameter, the weight of the target object, or the constant infusion parameter.
After acquiring the first physiological parameter, the infusion device determines whether the first physiological parameter exceeds the preset range of physiological parameters. For example, when the drug infused by the infusion device is an anesthetic, the preset range of physiological parameters refers to a BIS range. The preset range of physiological parameters may be set by the healthcare personnel. Furthermore, the physiological parameters included in the preset range of physiological parameters are not limited to BIS, but may also be other cardiac parameters.
In an embodiment, the infusion device is provided with a display screen, and the infusion device outputs a setting page for the physiological parameter range. The healthcare personnel may enter the physiological parameter range on the setting page. The infusion device, when detecting a setting operation of the physiological parameter range triggered on the setting page, acquires the input physiological parameter according to the setting operation and sets a preset range of physiological parameters according to the input physiological parameter. The setting operation may be a click operation of a setting button on the control page, i.e., after the healthcare personnel inputs the physiological parameters on the setting page, the healthcare personnel clicks the setting button, and the infusion device detects the setting operation. It should be noted that the healthcare personnel needs to input two physiological parameters, so that the infusion device can generate the preset range of physiological parameters according to the two physiological parameters.
In another embodiment, the infusion device may be communicatively connected to the control device, and the healthcare personnel may input the physiological parameters to the infusion device via the control device. That is, the control device transmits the physiological parameters inputted by the healthcare personnel as well as an identification of the healthcare personnel to the infusion device, and the infusion device determines, according to the identification, whether or not the healthcare personnel has the setting privilege. If it is determined that the healthcare personnel has the setting privilege, the infusion device sets the preset range of physiological parameters according to the physiological parameters.
In this embodiment, the set infusion parameters is set according to the experience of the healthcare personnel, and the preset range of physiological parameters is also set according to the experience of the healthcare personnel. When the first physiological parameter exceeds the preset range of the physiological parameters, it can be determined that the state of the target object is stable, and there is no need to perform infusion according to the set infusion parameter, i.e., there is no need for the healthcare personnel to manually control the infusion parameters of the infusion device, so the infusion device can determine the infusion parameters on its own and perform the infusion of the target object according to the set infusion parameter. When the infusion device determines that the first physiological parameter exceeds that preset range of physiological parameters, it determines the target infusion parameter according to the target parameters, thereby controlling the infusion device to infuse the target object according to the target infusion parameters. The target parameter includes the first physiological parameter, the weight of the target object, or a constant infusion parameter.
In this embodiment, when the infusion device detects that the physiological parameter of the target object falls outside of a preset range of physiological parameters, it automatically adjusts the infusion parameters of the infusion device by the physiological parameter, the body weight of the target object, or the constant infusion parameter, without requiring the healthcare personnel to manually switch the operating mode of the infusion device for adjusting the infusion parameters, which improves the operation efficiency of the infusion device.
As shown in
Step S301, when the infusion device enters the first operating mode, the target object is infused according to the set infusion parameter.
In this embodiment, the infusion device first operates according to the first operating mode, and the first operating mode is, for example, a total intravenous controlled anesthesia (TIVA) mode, in which the infusion device infuses the target object according to the infusion parameters set by the healthcare personnel. That is, when the infusion device enters the first operating mode, the infusion device infuses the target object according to the set infusion parameter.
Step S302, when the first physiological parameter exceeds the preset range of the physiological parameters, a second operating mode to be switched for the first operating mode is determined, and the infusion device is run in the second operating mode.
Step S303, a target parameter is determined according to the second operating mode, and a target infusion parameter is determined according to the target parameter.
Step S304, the target object is infused according to the target infusion parameter, in which the target parameter includes the first physiological parameters, the weight of the target object, or the constant infusion parameters.
When the first physiological parameter exceeds the preset range of the physiological parameters, the infusion device determines a second operating mode in which the first operating mode is to be switched, thereby determining the target parameter according to the second operating mode, then determining the target infusion parameter according to the target parameter, and finally infusing the target object with the infusion parameter according to the target infusion parameter. The second operating modes are different, and the target parameters are different. There is a plurality of operating modes in the infusion device, and the currently running operating mode is defined as the first operating mode. For example, the second operating mode to be switched may be determined by at least one of the information such as the drug infused in the target object, the weight parameter of the target object, the physiological parameter, and the like. Each of the operating modes is associated with a drug, a weight parameter, and a physiological parameter. The infusion device acquires the infused drug, the weight parameter of the target object, and the physiological parameter of the target object, and then compares and matches the selected infused drug, the weight parameter of the target object, and the physiological parameter with the drug, the weight parameter, and the physiological parameter associated with each of the operating modes, so as to determine the second operating mode to be determined. For example, when the drug currently being infused is an anesthetic, the operating modes associated with the anesthetic include a weight mode, an auto-adjustment mode, and a constant rate mode. If it is determined that the target object is a thin child according to the weight parameter of the target object, and only the weight mode is associated with the infusion with child and weight, and thus the weight mode is the second operating mode to be switched. If it is determined that the target object is an adult according to the physiological parameter of the target object, since adult infusion is associated with an auto-adjustment mode as well as a constant rate mode, and the infusion parameters are determined to require automatic adjustment for the infusion of the drug through the physiological parameters of the target object, the auto-adjustment mode serves as the second operating mode to be switched. It is to be noted that the above is merely for illustrative purposes and does not limit the manner in which the second operating mode is determined.
In this embodiment, the operating mode of the infusion device is adjusted to fit the infusion situation of the target object through the drug to be infused and the physiological characteristics of the target object, resulting in a high infusion flexibility of the infusion device.
In an embodiment, when the second operating mode is an auto-adjustment mode, then the first physiological parameter is determined as the target parameter. For example, the auto-adjustment mode may be a target-controlled infusion (TCI) mode, then the first physiological parameter is a BIS value.
In another embodiment, when the second operating mode is the weight mode, the weight of the target subject is determined as the target parameter, i.e., the weight of the target subject should be referred to when determining the target infusion parameter. For example, a correction coefficient may be determined by the weight of the target object, and a target correction parameter is obtained by correcting the first infusion parameter with the correction coefficient. The first infusion parameter is an infusion parameter set in the weight mode.
In yet another example, when the second operating mode is the constant rate mode, the constant infusion parameter is determined as the target parameter, i.e., the infusion device infuses the target object according to the constant infusion parameter. The constant infusion parameter include a constant flow rate, a constant infusion time, a set infusion concentration, and a constant infusion volume.
In the conventional technologies, the mode of the infusion device needs to be switched manually, e.g., the infusion device outputs a voice prompt when it detects that the mode switching needs to be performed in order to wait for the manual switching. In contrast, in this embodiment, the infusion device is capable of automatically switching the first operating mode to the second operating mode. Further, the mode switching of the infusion device includes automatic switching as well as manual switching, and the automatic switching as well as the manual switching of the infusion device needs to be set. If a plurality of infusion devices are connected to the same local area network, in which one of the working infusion devices carries out the automatic switching of modes, and the other infusion devices also carry out the automatic switching of modes when they are working, so as to avoid setting up the automatic switching of modes for each of the infusion devices one by one.
In this embodiment, after the infusion device is switched from the first operating mode to the second operating mode, the target parameter is determined by the second operating mode, so that the target infusion parameter matching the second operating mode is determined according to the target parameter.
As shown in
Step S401, a physiological characteristic of the target object is acquired.
Step S402, a target model matched with the physiological characteristic is acquired.
Step S403, a target parameter is inputted to the target model, and a target infusion parameter output by the target model is obtained.
In this embodiment, the infusion device may find a suitable operating mode to set the target infusion parameters for the infusion device through the difference in the physiological characteristics of the target object.
The operating mode is obtained by using, as ML/AI training data, the data among the user, the target parameters, and the infusion parameters of the user with not much difference in physiological characteristics. The physiological characteristics include weight, age, gender, height, and the like of the users, i.e., the physiological characteristics, the target parameters, and the infusion parameters of the users belonging to the same group used in the infusion are used for training to obtain the operating mode corresponding to the group. The operating mode is stored in association with the identity of the group.
The infusion device stores information about the target object, and the infusion device obtains physiological characteristics of the target object from the information about the target object. The infusion device can determine the group to which the target object belongs by the physiological characteristics, so as to obtain an operating mode matched with the target object as the target model through the group.
The infusion device inputs the target parameters into the target model, and the target model outputs the target infusion parameter according to the target parameter.
In addition, the operating mode associated with the identification of the group is stored in a server, and the infusion device sends the physiological characteristics of the target object to the server to request the server to send the target model matched with the target object, and then inputs the target parameters into the target model to obtain the target infusion parameters.
In this embodiment, the infusion device acquires the physiological characteristics of the target object, thereby obtaining a target model matched with the physiological characteristics. Then the target parameters are inputted into the target model to obtain the target infusion parameters, i.e., the infusion device accurately determines the target infusion parameters according to the physiological characteristics of the target object.
As shown in
Step S501, a second physiological parameter of the target object is acquired.
Step S502, when the second physiological parameter is in the preset range of the physiological parameters, the target object is infused according to the set infusion parameter.
In this embodiment, after infusing the target object according to the target infusion parameters, the infusion device continues to acquire physiological parameters of the target object, and the acquired physiological parameters are defined as the second physiological parameters.
The infusion device determines whether the second physiological parameter is in a preset range of physiological parameters. If the second physiological parameter is in the preset range of the physiological parameters, the infusion device is required to perform the infusion of the target object according to the set infusion parameter.
When the infusion device is in the first operating mode, the target object is infused according to the set infusion parameter. If the physiological parameter of the target object exceeds the preset range of the physiological parameters, the infusion device is switched to the second operating mode, so that the infusion device infuses the target object according to the target parameters determined by the target parameters. If the physiological parameter of the target object is in the preset range of the physiological parameters, the infusion device is switched to the first operating mode to operate according to the set infusion parameter.
In this embodiment, the infusion device acquires the second physiological parameter of the target object, and if the second physiological parameter is in the preset range of the physiological parameters, the infusion device infuses the target according to the set infusion parameter.
As shown in
Step S601, a physiological characteristic of the target object is acquired.
Step S602, the physiological characteristic and the set infusion parameter are inputted to a prediction model to obtain the current first physiological parameter of the target object output by the prediction model.
In this embodiment, the infusion device is provided with the prediction model, and the prediction model may be used to predict the first physiological parameter of the user. For example, the first physiological parameter may be a concentration of an anesthetic agent in the user's body, i.e., the prediction model may predict the concentration of the anesthetic agent in the user's body. The prediction model is trained by the physiological characteristics of the user, the infusion parameters of the infusion device employed by the user, and the physiological parameters of the user.
The device obtains the physiological characteristic of the target object, and the physiological characteristic include weight, height, gender, and age of the target object. The device inputs the set infusion parameters and the physiological characteristics into the prediction model to obtain a first current physiological parameter of the target object output by the prediction model.
In this embodiment, the infusion device can predict the current first physiological parameter of the target object by inputting the physiological parameters of the target object and the set infusion parameters into the prediction model, and there is no need to use the device to collect the physiological parameters of the target object, which saves costs.
