[0019] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0020] Reference Figure 1 , a flowchart 100 of some embodiments of an infusion control method for multi-liquid drugs according to the present disclosure is shown. The infusion control method for multi-liquid drugs includes the following steps: Step 101, in response to detecting that at least one infusion control component is fixed on the rotating cylinder, and each infusion control component in at least one infusion control component package is bound to a corresponding liquid drug, determine a target infusion control component according to the infusion sequence information.

[0021] In some embodiments, an execution subject (e.g., a computing device) of the infusion control method for multi-liquid drugs can, in response to detecting that at least one infusion control component is fixed on the rotating cylinder, and each infusion control component in at least one infusion control component package is bound to a corresponding liquid drug, determine a target infusion control component according to the infusion sequence information. Among them, the target infusion control component is the infusion control component corresponding to the liquid drug to be infused among the above at least one infusion control component. The rotating cylinder is a device for fixing the infusion control component. In practice, at least one rotating component is linearly arranged on the rotating cylinder. The rotating component includes: a rotating shaft and a power supply loop. The rotating shaft is used to control the rotation of the infusion control component. The power supply component supplies power to the infusion control component through the power supply loop. The above execution subject detects whether at least one infusion control component is fixed on the rotating cylinder through a current detector. In addition, medical staff bind the infusion control component and the liquid drug through a medical care terminal.

[0022] As an example, refer to Figure 2 the structural schematic diagram of the rotating cylinder shown, where the rotating cylinder includes: a support rod 1 and at least one rotating component 2. Specifically Figure 2 7 linearly arranged rotating components 2 are shown. Any number of rotating components 2 can be arranged on the support rod 1 according to actual needs. Further, refer to Figure 3Schematic structural diagram of the rotating assembly shown, wherein the rotating assembly includes: a rotating shaft 3, a power supply loop 4, and a communication loop 5. When the infusion control assembly is fixed to the rotating assembly, it can rotate by the rotation of the rotating shaft. The power supply contacts in the infusion control assembly are in contact with the power supply loop 4 to supply power to the infusion control assembly. The communication contacts in the infusion control assembly are in contact with the communication loop 5 to conduct data communication. Immediately afterwards, refer to Figure 4 Schematic diagram of the application scenario corresponding to the rotating cylinder and the infusion control assembly shown, wherein the upper and lower ends of the support rod 1 included in the rotating cylinder can adopt an internal thread structure so that it can be installed on the infusion stand by replacing the rod body. According to the infusion needs of the patient, the infusion control assembly 6 can be fixed on the rotating assembly 2. Figure 4 Five rotating assemblies 2 are shown on the rotating cylinder, and two infusion control assemblies 6 are installed on the rotating assembly 2. The liquid medicine in the liquid bottle is connected through an infusion tube, and the liquid control assembly 6 controls the infusion by clamping the infusion tube.

[0023] It should be noted that the above computing device can be hardware or software. When the computing device is hardware, it can be implemented as a single terminal device. When the computing device is embodied as software, it can be installed in the above-listed hardware devices. It can be implemented as a single software or software module. No specific limitation is made here.

[0024] Step 102, determine whether a drip chamber and an infusion tube are fixed in the tube bundle area included in the target infusion control assembly.

[0025] In some embodiments, the above execution subject can determine whether a drip chamber and an infusion tube are fixed in the tube bundle area included in the target infusion control assembly in various ways. Among them, the tube bundle area is an area for fixing the infusion tube and the drip chamber and for controlling the infusion.

[0026] In some optional implementation manners of some embodiments, the above execution subject determines whether a drip chamber and an infusion tube are fixed in the tube bundle area included in the above target infusion control assembly, including: The first step is to control the flow rate control component included in the above target infusion control assembly to extend by a preset increment.

[0027] In practice, the infusion control assembly includes: a second control assembly, a fixing assembly, a first flow rate detector, a second flow rate detector, and a flow rate control assembly. Among them, the second control assembly includes: a second control unit and a second communication unit. Among them, the second communication unit is used for duplex communication with the first communication unit, and the second control unit is used to control the flow rate control assembly to perform infusion control according to the control instruction sent by the first control unit through the first communication unit. The first flow rate detector, the second flow rate detector, and the flow rate control assembly are all arranged on the inner wall of the fixing assembly. A tube bundle area is arranged in the fixing assembly to fix the drip chamber and the infusion tube. The first flow rate detector includes: a transmitting end and a receiving end. The second flow rate detector includes: a transmitting end and a receiving end. The transmitting end and the receiving end are arranged opposite to each other. The transmitting end is used to emit an optoelectronic signal, and the receiving end is used to receive the optoelectronic signal.

[0028] As an example, refer to Figure 5 the perspective view of the infusion control assembly shown in the front view, and Figure 6 the top view of the infusion control assembly shown in the figure, where the infusion control assembly includes: a fixing assembly 7, a first flow rate detector 8, a second flow rate detector 9, and a flow rate control assembly 10. Among them, the infusion control assembly can be fixed to the rotating assembly through the fixing assembly 7 so that the infusion control assembly rotates with the rotating shaft on the rotating assembly. In particular, the inner wall of the fixing assembly 7 connected to the rotating shaft is provided with a power supply contact and a communication contact. When the infusion control assembly is fixed to the rotating assembly, the power supply contact is connected to the power supply loop, and the communication contact is connected to the communication loop so that the infusion control assembly can still be powered and communicate while rotating with the rotating assembly. Further, the first flow rate detector 8 and the second flow rate detector 9 are arranged in the same direction on the inner wall of the fixing assembly 7 for fixing the drip chamber and the infusion tube. The flow rate control assembly 10 and the first flow rate detector 8 are arranged opposite to each other. Specifically, when the drip chamber and the infusion tube are fixed inside the fixing assembly 7, the first flow rate detector 8 is arranged on the inner wall of the fixing assembly 7 above the drip chamber for fixing the drip chamber and the infusion tube to detect the liquid flow rate in the infusion tube above the drip chamber. The second flow rate detector 9 is arranged on the inner wall of the fixing assembly 7 below the drip chamber for fixing the drip chamber and the infusion tube to detect the liquid flow rate in the infusion tube below the drip chamber. The flow rate control assembly 10 is arranged on the inner wall of the fixing assembly 7 between the second flow rate detection device 9 and the drip chamber for fixing the drip chamber and the infusion tube. Specifically, the flow rate control assembly 10 is composed of a push rod and a silicone head, and controls the flow rate by pressing the infusion tube. The first flow rate detector 8 includes: a transmitting end and a receiving end. The second flow rate detector 8 includes: a transmitting end and a receiving end. The transmitting end and the receiving end are arranged opposite to each other. The transmitting end is used to emit an optoelectronic signal, and the receiving end is used to receive the optoelectronic signal.

[0029] In the second step, in response to a torque change occurring in the flow rate control assembly included in the target infusion control assembly, determine the current torque value sequence.

[0030] In practice, there is a margin between the flow rate control component and the infusion tube. As the flow rate control component extends and contacts the infusion tube, the torque will change. Therefore, the torque value when the torque changes is collected as the current torque value sequence.

[0031] In the third step, in response to the standard deviation of the torque values corresponding to the above current torque value sequence being less than or equal to the preset torque value standard deviation and the torque values of the latter preset proportion of the current torque values in the above current torque value sequence converging, a control instruction is generated to indicate that a drip chamber and an infusion tube are fixed in the bundle tube area included in the target infusion control component.

[0032] Among them, the above control instruction is used to control the first flow rate detector and the second flow rate detector included in the target infusion control component to turn on and perform drug flow rate detection. In practice, the infusion tube has a certain elasticity. By judging the difference between the standard deviation of the torque value and the preset torque standard deviation, it is judged whether the infusion tube is fixed in the fixing component 7, so as to ensure the overall robustness of the device. The preset proportion can be 30%.

[0033] Step 103, in response to being fixed, according to the first flow rate detector and the second flow rate detector included in the target infusion control component, determine the first drug flow rate and the second drug flow rate.

[0034] In some embodiments, in response to being fixed, the above execution subject may determine the first drug flow rate and the second drug flow rate according to the first flow rate detector and the second flow rate detector included in the target infusion control component.

[0035] In some optional implementation manners of some embodiments, the above execution subject determines the first drug flow rate and the second drug flow rate according to the first flow rate detector and the second flow rate detector included in the target infusion control component, including: In the first step, when liquid drug is not being delivered through the infusion tube, an optical signal is emitted through the transmitting end included in the first flow rate detector, and the optical signal is received through the receiving end included in the first flow rate detector to obtain a first optical signal.

[0036] In practice, since the first flow rate detector is a non-contact flow rate detection, the optical signal emitted by the transmitting end will undergo a certain refraction when passing through the infusion tube. Therefore, by determining the first optical signal, the attenuation of the optical signal after passing through the infusion tube when liquid drug is not being delivered is obtained.

[0037] In the second step, when liquid drug is not being delivered through the infusion tube, an optical signal is emitted through the transmitting end included in the second flow rate detector, and the optical signal is received through the receiving end included in the second flow rate detector to obtain a second optical signal.

[0038] In practice, since the second flow rate detector performs non-contact flow rate detection, the optical signal emitted by the transmitting end will undergo certain refraction when passing through the infusion tube. Therefore, by determining the second photoelectric signal, the attenuation of the photoelectric signal after passing through the infusion tube when no liquid drug is being delivered can be obtained.

[0039] In the third step, when liquid drug is being delivered through the infusion tube, an optical signal is emitted by the transmitting end included in the first flow rate detector, and the optical signal is received by the receiving end included in the first flow rate detector to obtain a third photoelectric signal.

[0040] In practice, multiple sensitive thin sheets are arranged horizontally inside the infusion tube and the first flow rate detection device. The liquid drug can pass through the sensitive thin sheets. In particular, when the liquid drug flows, pressure is exerted on the sensitive thin sheets, causing the sensitive thin sheets to bend and thus block the optical signal. As the flow rate of the liquid drug increases, the sensitive thin sheets will bend further, thereby increasing the blockage of the optical signal. By judging the attenuation of the optical signal, the corresponding liquid flow rate can be mapped. By designing a replacement part of the infusion tube with sensitive thin sheets, the flow rate of the infusion liquid can be accurately measured without invasion, and at the same time, the implementation cost is greatly reduced.

[0041] As an example, refer to Figure 7 the schematic diagram of the acquisition process of the first photoelectric signal and the third photoelectric signal shown in the figure. Among them, when no liquid drug is being delivered, the sensitive thin sheets are in a horizontal state, and the first photoelectric signal collected at this time is the photoelectric signal after refraction (with a certain signal attenuation) through the infusion tube. When liquid drug is being delivered, as the flow rate of the liquid drug increases, the center of the sensitive thin sheets will bend accordingly, and at this time, the refraction of the optical signal will be further increased. By collecting the third photoelectric signal (the signal attenuation after passing through the bent sensitive thin sheets), the flow rate of the liquid drug is determined according to the attenuation of the photoelectric signal. Among them, the second photoelectric signal and the fourth photoelectric signal are the same in principle and will not be elaborated here.

[0042] As another example, in particular, considering that directly integrating the sensitive thin sheets into the infusion tube has a high implementation cost, and at the same time, due to the high sensitivity of the sensitive thin sheets, the transportation of the infusion tube will also affect the accuracy of the sensitive thin sheets. Therefore, refer to Figure 8 the schematic diagram of the position of the replacement part of the infusion tube shown in the figure. Among them, the upper and lower parts of the drip chamber can adopt the method of replacing the infusion tube. The part of the infusion tube containing the sensitive thin sheets is replaced by the replacement part of the infusion tube to reduce the cost.

[0043] In the fourth step, when liquid drug is being delivered through the infusion tube, an optical signal is emitted by the transmitting end included in the second flow rate detector, and the optical signal is received by the receiving end included in the second flow rate detector to obtain a fourth photoelectric signal.

[0044] In the fifth step, using the above-mentioned first optoelectronic signal as a noise signal, noise elimination is performed on the above-mentioned third optoelectronic signal to obtain a fifth optoelectronic signal.

[0045] In practice, infusion tubes made of different materials have different refractive abilities for optoelectronic signals. To avoid the influence of the noise generated by the refraction of optoelectronic signals by the infusion tube on the analysis of the third optoelectronic signal, it is necessary to use the first optoelectronic signal as the noise signal to perform noise elimination on the third optoelectronic signal. In particular, it should be noted that since the third optoelectronic signal is obtained by further refraction acquisition based on the sensitive thin sheet, that is, the signal intensity of the third optoelectronic signal is further attenuated compared with the first optoelectronic signal. Therefore, directly subtracting the first optoelectronic signal from the third optoelectronic signal will result in a negative value for the signal. Therefore, it is necessary to perform signal inversion on the basis of subtracting the first optoelectronic signal from the third optoelectronic signal as the fifth optoelectronic signal.

[0046] In the sixth step, using the above-mentioned second optoelectronic signal as a noise signal, noise elimination is performed on the above-mentioned fourth optoelectronic signal to obtain a sixth optoelectronic signal.

[0047] In practice, for the generation method of the sixth optoelectronic signal, refer to the above-mentioned fifth step and will not be elaborated here.

[0048] In the seventh step, based on the above-mentioned fifth optoelectronic signal, the above-mentioned first drug flow rate is determined.

[0049] In practice, assuming that the delivery of liquid drugs is a uniform motion under the action of gravity, therefore, the first drug flow rate can be determined according to the mapping relationship between the intensity of the fifth optoelectronic signal and the preset drug flow rate. Specifically, the mapping relationship between the drug flow rate and the optoelectronic signal can be obtained by induction through experimental methods.

[0050] In the eighth step, based on the above-mentioned sixth optoelectronic signal, the above-mentioned second drug flow rate is determined.

[0051] In practice, assuming that the delivery of liquid drugs is a uniform motion under the action of gravity, therefore, the second drug flow rate can be determined according to the mapping relationship between the intensity of the sixth optoelectronic signal and the preset drug flow rate. Specifically, the mapping relationship between the drug flow rate and the optoelectronic signal can be obtained by induction through experimental methods.

[0052] Step 104, in response to the first drug flow rate not being 0 and the second drug flow rate not being 0, determine the drug flow rate difference according to the infusion control information corresponding to the target infusion control component, the first drug flow rate, and the second drug flow rate.

[0053] In some embodiments, the above-mentioned execution entity may, in response to the first drug flow rate not being 0 and the second drug flow rate not being 0, determine the drug flow rate difference according to the infusion control information corresponding to the target infusion control component, the first drug flow rate, and the second drug flow rate. In practice, affected by gravity and the air pressure in the infusion tube, the first drug flow rate is greater than or equal to 0, and the second drug flow rate is greater than or equal to 0. The infusion control information includes: the volume of liquid drug and the infusion completion time.

[0054] In practice, on the premise of knowing the volume of liquid drug, the infusion completion time, and the diameter of the infusion tube, the preset drug flow rate can be obtained. Specifically, first, the volumetric flow rate can be obtained according to the volume of liquid drug and the infusion completion time. Then, according to the volumetric flow rate and the diameter of the infusion tube, the preset drug flow rate can be obtained.

[0055] Drug flow rate difference = min((the first drug flow rate - the preset drug flow rate), (the second drug flow rate - the preset drug flow rate)). For example, the preset drug flow rate is 30, the first drug flow rate is 40, and the second drug flow rate is 20. Then the drug flow rate difference = min((40 - 30), (20 - 30)) = -10. For example, the preset drug flow rate is 30, the first drug flow rate is 40, and the second drug flow rate is 30. Then the drug flow rate difference = min((40 - 30), (30 - 30)) = 0. For example, the preset drug flow rate is 30, the first drug flow rate is 40, and the second drug flow rate is 35. Then the drug flow rate difference = min((40 - 30), (35 - 30)) = 5.

[0056] Step 105, in response to the drug flow rate difference being greater than the first preset flow rate difference, perform infusion flow rate limiting through the flow rate control component included in the target infusion control component.

[0057] In some embodiments, in response to the drug flow rate difference being greater than a first preset flow rate difference, the above-mentioned execution entity performs infusion flow rate limiting through the flow rate control component included in the target infusion control component. In practice, the above-mentioned execution entity can control the extension of the flow rate control component included in the target infusion control component to perform infusion flow rate limiting. Specifically, the mapping relationship between the pressure exerted by the flow rate control component and the flow rate can be constructed, and then the flow rate control component can be controlled to extend to perform infusion flow rate limiting. It is also possible to control the flow rate control component to extend in an incremental form and re-determine the drug flow rate difference to determine whether to further control the extension of the flow rate control component to perform infusion flow rate limiting. Among them, the first preset flow rate difference is the upper boundary of the flow rate difference range, and the second preset flow rate difference is the lower boundary of the above-mentioned flow rate difference range. Specifically, by setting the first preset flow rate difference as the upper boundary and the first preset flow rate difference as the lower boundary, the flow rate difference redundancy can be obtained. When the drug flow rate difference is less than the lower boundary (the second preset flow rate difference), it indicates that flow rate acceleration is required. For example, the preset drug flow rate is 30. The first drug flow rate is 40. The second drug flow rate is 20. Then the drug flow rate difference = min((40 - 30), (20 - 30)) = -10. At this time, infusion acceleration is required. Another example, the first drug flow rate is 40. The second drug flow rate is 35. Then the drug flow rate difference = min((40 - 30), (35 - 30)) = 5. At this time, infusion flow rate limiting is required.

[0058] In some optional implementation manners of some embodiments, the above-mentioned execution entity can, in response to the above-mentioned drug flow rate difference being greater than the first preset flow rate difference, perform infusion flow rate limiting through the flow rate control component included in the above-mentioned target infusion control component, including: Under the condition that the first drug flow rate is greater than or equal to the preset infusion speed, control the flow rate control component included in the target infusion control component to exert pressure on the infusion tube to achieve infusion flow rate limiting. Among them, the pressure value exerted by the flow rate control component is proportional to the drug flow rate.

[0059] Step 106, in response to the drug flow rate difference being less than the second preset flow rate difference, perform infusion flow rate acceleration through the flow rate control component included in the target infusion control component.

[0060] In some embodiments, the above-mentioned execution entity can, in response to the drug flow rate difference being less than the second preset flow rate difference, perform infusion flow rate acceleration through the flow rate control component included in the target infusion control component. Among them, the first preset flow rate difference is the upper boundary of the flow rate difference range, and the second preset flow rate difference is the lower boundary of the above-mentioned flow rate difference range. Specifically, by setting the first preset flow rate difference as the upper boundary and the first preset flow rate difference as the lower boundary, the flow rate difference redundancy can be obtained.

[0061] In some alternative implementations of some embodiments, in response to the above drug flow rate difference being less than a second preset flow rate difference, the infusion flow rate is increased through the flow rate control component included in the above target infusion control component, including: Under the condition that the second drug flow rate is greater than or equal to the preset infusion rate, control the flow rate control component included in the target infusion control component to reduce the pressure on the infusion tube to achieve an increase in the infusion flow rate.

[0062] In some alternative implementations of some embodiments, the above method further includes: First step, in response to the first drug flow rate being 0 and the second drug flow rate not being 0, control the flow rate control component included in the above target infusion control component to perform an infusion stop operation.

[0063] In practice, the flow rate control component can be controlled to slowly apply pressure to the infusion tube to gradually stop the infusion of the liquid drug. The purpose of slowly applying pressure is that there may still be a part of the liquid drug in the drip chamber. Therefore, when slowly applying pressure, the liquid drug in the drip chamber can be infused into the patient's body before the infusion is completely stopped.

[0064] Second step, in response to the first drug flow rate being 0, the second drug flow rate being 0, and the liquid drug corresponding to the target infusion control component being the last liquid drug to be infused in the above infusion sequence information, send an infusion completion reminder for the liquid drug corresponding to the above target infusion control component to the medical care terminal.

[0065] In practice, by sending a reminder to the medical care, the pressure on medical staff to frequently check the infusion progress of the liquid drug can be alleviated.

[0066] Third step, in response to the first drug flow rate being 0, the second drug flow rate being 0, and the liquid drug corresponding to the target infusion control component not being the last liquid drug to be infused in the above infusion sequence information, re-determine the target infusion control component according to the above infusion sequence information and perform the infusion control of the liquid drug.

[0067] In practice, when the liquid drug corresponding to the target infusion control component is not the last liquid drug to be infused in the above infusion sequence information, the above execution subject re-selects an infusion control component from at least one infusion control component as the target infusion control component, and steps 101 to 106 are executed again.

[0068] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: Through the infusion control method for multi-liquid drugs applied in some embodiments of the present disclosure, the automated infusion control of multi-liquid drugs is realized, the accuracy of infusion flow rate and infusion sequence control is improved, and at the same time, the occurrence of blood reflux or air thrombus in patients is effectively avoided.

In practice, modular infusion control is realized through the infusion control component, so that the infusion control component can be flexibly selected according to the number of liquid drugs to be infused. Secondly, it is determined whether a drip chamber and an infusion tube are fixed in the bundle tube area included in the above-mentioned target infusion control component. Then, in response to the fixation, the first drug flow rate and the second drug flow rate are determined according to the first flow rate detector and the second flow rate detector included in the above-mentioned target infusion control component. In this way, automated flow rate detection is realized, which is convenient for subsequent accurate flow rate control. In particular, in order to avoid control failures or ineffective control of the flow rate control component, the flow rates before and after flow rate control are respectively detected by the first flow rate detector and the second flow rate detector to ensure the accuracy of flow rate detection. Then, in response to the first drug flow rate not being 0 and the second drug flow rate not being 0, the drug flow rate difference is determined according to the infusion control information, the first drug flow rate, and the second drug flow rate corresponding to the above-mentioned target infusion control component, where the infusion control information includes: the volume of the liquid drug and the infusion completion time. Further, in response to the above-mentioned drug flow rate difference being greater than the first preset flow rate difference, the infusion flow rate is limited by the flow rate control component included in the above-mentioned target infusion control component.

Through this method, the automated infusion control of multi-liquid drugs is realized, the accuracy of infusion flow rate and infusion sequence control is improved, and at the same time, the occurrence of blood reflux or air thrombus in patients is effectively avoided.
