[0002] When using injectable drugs in hospitals, doctors usually prepare target drugs of different concentrations based on the patient's age, gender, physique, and condition. For example, in the existing anesthesia department, when using drugs, it is necessary to accurately control the concentration and dosage of the drugs to ensure that the patient enters an anesthetized state while avoiding serious damage to the human body caused by drug overdose.

[0003] The process of adjusting the drug concentration is the same as the traditional dilution principle, that is, the solvent drug and the solute drug are mixed to form target drugs of different concentrations. The existing medical personnel adjust the drug concentration by extracting the solute drug through a syringe and then transferring it to the bottle of the solvent drug to achieve the process of adjusting the drug concentration. The defects of this method are: first, personnel are required to calculate the required amount of solvent drug and solute drug, and all calculations and operations must be checked by two people, which is cumbersome. At the same time, the reliability of the results calculated by personnel is poor. Second, the solvent drug and the solute drug are configured once during configuration, that is, an excessive amount of target concentration drug is generally configured for use, which is wasteful. Third, for the high-precision configuration process, manual configuration by personnel may result in misoperation, resulting in drug waste. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0019] First embodiment of the drug concentration adjustment system refer to Figure 1 , the first embodiment of the drug concentration adjustment system is described in detail.

[0020] The first embodiment of the drug concentration adjustment system of the present invention includes an information input / display device 1, a processing device 2 and a pumping device 3, wherein the information input / display device 1 is used to assist personnel in inputting original drug concentration and target drug concentration information, as well as the pumping device 3 number information corresponding to each original drug, and displaying relevant information of the drug concentration adjustment process. The information input / display device 1 can be a touch screen, which realizes human-computer interaction by displaying a human-computer interaction screen. For example, a variety of target drug concentration options commonly used in clinical practice are displayed on the touch screen, and personnel can input target concentration drugs by clicking on the corresponding options, or input target drug concentration information and original drug concentration information through the input box. Of course, the touch screen is only one implementation method of the information input / display device 1, and it can also use a non-touch screen combined with a mouse to realize the above functions. The processing device 2 is connected to the information input / display device 1, and is used to automatically calculate the discharge speed of each original drug according to the target drug concentration and original drug concentration input by the personnel, and send a control signal to control the pumping device 3, so that a variety of After the original drugs are output and mixed, a drug of a target concentration is formed. For example, a common 1mg / ml norepinephrine needs to be diluted to 2ug / ml for use. Then 2ug / ml norepinephrine is the target drug concentration information, and 1mg / ml norepinephrine and the used diluent solution (such as 5% glucose injection) are used as the original drug concentration information. The processing device 2 calculates the drug discharge speed required for configuring multiple original drug concentrations into the target drug concentration according to the target drug concentration information and the original drug concentration information used. For example, if the norepinephrine is diluted to 2ug / ml, it is diluted to 500 times for use, so the ratio of the delivery speed of the original drug 1mg / ml norepinephrine to the diluent should be 1 / 499, so that the diluent and 1mg / ml norepinephrine can be mixed to form a target concentration of 2ug / ml in real time. The pump device 3 is connected to the processing device 2, and can receive the control signal of the processing device 2, and control the output speed of the original drug solution according to the control signal. In order to ensure that the error of the target concentration drug is small after mixing, the existing method such as Fig. 9 and Fig.10The infusion pump 13 and / or injection pump 14 in the apparatus has an error of less than 5% in the existing conventional infusion pump 13 and injection pump 14, and the accuracy can be further adjusted as needed. It is an instrument that can accurately control the number of infusion drops and the infusion flow rate to ensure that the drug can be delivered to the human body at a uniform speed and an accurate and safe amount. It has been maturely used in the drug injection and infusion process of critically ill patients, so the specific structure of the infusion pump 13 and the injection pump 14 is not described here. The present invention utilizes the infusion pump 13 and the injection pump 14 not to input the drug solution into the human body, but to output a variety of original drugs at different speeds into a mixing container 18, so as to adjust the drug concentration and obtain the target concentration of the drug in real time.

[0021] The second embodiment of the drug concentration adjustment system of the present invention.

[0022] refer to Figure 2 Compared with the first embodiment of the drug concentration adjustment system, the second embodiment of the drug concentration adjustment system is further provided with a prompting device 4, which is connected to the information input / display device 1. Through the target concentration drug information input by the personnel, the prompting device 4 prompts the selection method of the original concentration drug that can be configured as the target concentration drug, so that the personnel can select it as the input of the original concentration drug information, thereby improving the efficiency of the personnel's information input. For example, the personnel inputs the target concentration drug information as 2ug / ml of norepinephrine through the information input / display device 1, and the prompting module 8 displays the combination method according to the pre-set clinically commonly used 1mg / ml norepinephrine or 0.1mg / ml norepinephrine and the dilution solvent combination method, and displays the combination method through the information input / display device 1 for the personnel to select. For example, the personnel selects the combination method of 1mg / ml norepinephrine and the dilution solvent as the original drug information for input, and the processing device 2 calculates the delivery speed ratio of each original drug according to the information, and outputs each original drug. Thus, through the prompting module 8, the efficiency of the personnel's information input can be quickly improved.

[0023] The third embodiment of the drug concentration adjustment system of the present invention.

[0024] refer to Figure 3Compared with the first or second embodiments, the third embodiment of the drug concentration adjustment system adds a monitoring device, which is connected to the processing device 2 and is used to monitor the volume of the target drug concentration in real time. By obtaining the control signal sent by the processing device 2 and the duration of the control signal, the volume output by each original drug can be obtained. The total volume of the target concentration drug is obtained by adding the volumes output by each original drug, and the total volume is displayed through the information input / display device 1, so that personnel can know the total volume of the target concentration drug in real time, so that the adjustment process of the target concentration drug can be stopped in time according to actual needs. Compared with the traditional manual adjustment of drug concentration by volume mixing, this method can stop the adjustment of the target concentration drug according to actual needs because it adjusts the drug concentration by real-time controlling the output speed of various original drugs, such as Fig.11 As shown, on the basis of the present invention, an infusion pump 13a can be additionally used to directly deliver the target concentration medicine obtained in the mixing container 18 into the human body through the medicine delivery tube 17 to avoid the waste of medicine.

[0025] At the same time, the present invention can also input the target concentration of the medicine to be obtained by the information input / display device 1. During the process of adjusting the medicine concentration, the volume of the current target concentration medicine can be displayed in real time through the monitoring device. When the target volume is reached, the monitoring device feeds back a signal to the processing device 2, so that the adjustment of the medicine concentration is terminated.

[0026] In a second aspect, the present invention also provides a method for adjusting the concentration of a drug, referring to Figure 4 , Figure 5 and Figure 6 The method for adjusting the drug concentration is explained in detail.

[0027] The first embodiment of the drug concentration adjustment method, referring to Figure 4 The method comprises the following steps: S1: information acquisition / display step, receiving the original drug concentration and target drug concentration information input by the personnel, as well as the input of the pump liquid device 3 number information corresponding to each original drug, and displaying the relevant information of the drug concentration adjustment process, for example, the infusion pump 13 is numbered as one, and the injection pump 14 is numbered as two below, and the processing device 2 controls the multiple pump liquid devices 3 to output the corresponding original drugs at different speeds in combination with the information; In the S2 processing step, the discharge speed required for configuring multiple original agent concentrations into the target agent concentration is calculated according to the original agent concentration and the target concentration agent information input by the personnel, and a control signal is issued, wherein the control signal is used to control the discharge speed of the multiple original agents.

[0028] From the above, it can be seen that in the drug concentration adjustment method provided by the present invention, personnel only participate in the input of the original drug concentration and the target concentration drug information, and the calculation and drug mixing processes are all performed by machines. Compared with manual drug concentration adjustment, it is more reliable and less prone to errors.

[0029] The second embodiment of the drug concentration adjustment method, referring to Figure 5 The method comprises the following steps: S1, information acquisition / display step, acquiring the target drug concentration information input by the personnel, as well as the input of the pump device 3 number information corresponding to each original drug and displaying the relevant information of the drug concentration adjustment process; Sa1, in the above information acquisition / display step, after obtaining the target drug concentration information input by the personnel, a prompting step is performed, in which the prompting step prompts the selection method of the original drug that can be configured to the target drug concentration for the personnel to select; In the S2 processing step, the discharge speed required for configuring multiple original agent concentrations into the target agent concentration is calculated according to the original agent concentration and the target concentration agent information input by the personnel, and a control signal is issued, wherein the control signal is used to control the discharge speed of the multiple original agents.

[0030] The third embodiment of the drug concentration adjustment method is as follows: Figure 6 , which adds a monitoring step based on the first embodiment or the second embodiment of the above-mentioned drug concentration adjustment method, and the monitoring step is performed simultaneously with the processing step, and is used to monitor the volume of the target concentration drug in real time; Specifically, the monitoring step can be divided into S3 first monitoring step or S4 second monitoring step, wherein the execution or non-execution of S3 first monitoring step and S4 second monitoring step is selected and executed according to whether the personnel sets the target concentration medicine for the target volume. When the S1 information acquisition / display step is executed, if the target concentration medicine information of the target volume set by the personnel is not obtained, then the S3 first monitoring step is executed for real-time monitoring of the target volume of the target concentration medicine. The S3 first monitoring step will not trigger the termination of the drug concentration adjustment process and is always in a continuous adjustment process. When the S1 step is executed, if the target concentration medicine information of the target volume set by the personnel is obtained, then the S4 second monitoring step is executed. Compared with the S3 first monitoring step, this step can automatically terminate after reaching the set target volume.

[0031] In a third aspect, the present invention also provides a drug concentration adjustment device, referring to Figure 7 and Figure 8 Provide detailed explanation.

[0032] The first embodiment of the drug concentration regulating device, referring to Figure 7, including an information acquisition / display module 5, a processing module 6 and a pump liquid driving module 7, wherein the information acquisition / display module 5 is used to receive the input of the original drug concentration and the target drug concentration information of the information acquisition / display device and display the relevant information of the drug concentration adjustment process, the processing module 6 is used to calculate the discharge speed required for configuring multiple original drug concentrations into the target drug concentration according to the input original drug concentration and the target drug concentration information, and send out a control signal, the control signal is used to control the discharge speed of multiple original drugs, and the pump liquid driving module 7 is used to receive the signal of the processing device 2 and control the pump liquid driving device to operate.

[0033] The second embodiment of the drug concentration regulating device, referring to Figure 8 On the basis of the first embodiment of the drug concentration regulating device, a prompting module 8 and / or a monitoring module 16 are added, wherein the prompting module 8 is used to prompt the personnel to select the original drug that can be configured to the target drug concentration when the personnel inputs the information of the target drug concentration, so that the personnel can make a selection and quickly input the selected original drug concentration information; the monitoring module 16 is used to monitor the volume of the configured target drug concentration in real time, and the monitoring module 16 can also provide real-time feedback of the volume of the drug with the current target concentration to the processing module 6.

[0034] Further, in order for those skilled in the art to more clearly understand the specific structure of the product when the present invention is applied in the industry, reference is made to Fig. 9 and Fig.10, which includes a host device 15, which is an electronic product integrating the functions of the information input / display device 1, the processing device 2, the prompting device 4 and the monitoring device in the above-mentioned drug concentration adjustment system. The pump device 3 can use the existing infusion pump 13 and / or the injection pump 14 to achieve a precise output speed of the original drug solution. The selection of the injection pump or the infusion pump 13 is determined according to the amount of the original drug. For example, if more dilution drugs are required, the infusion pump 13 can be used. The dilution drug container 9 realizes the output of the drug through the first output tube 10. The existing infusion pump 13 also realizes the precise output of the drug by controlling the first output tube 10, and For solute drugs, the amount required is generally small, so generally a syringe pump 14 can be used to draw the solute drug into the syringe 11, and cooperate with the second output tube 12 to output the drug. The existing syringe pump 14 controls the output of the drug by controlling the stroke of the squeezing syringe 11. The two drugs are output together to the inside of a containing space to achieve mixing and obtain a drug of target concentration. For example, in the above content, 1 mg / ml norepinephrine is used as a solute original drug, and its dosage is relatively small, so a syringe pump 14 can be used. 5% glucose injection is used as a solvent original drug. Due to its large dosage, an infusion pump 13 can be used. Although the above content uses the method of mixing two original drugs to obtain a drug of target concentration as an example, when the actual drug concentration is adjusted, there may be a situation where more than two original drugs are mixed to obtain a drug of target concentration. In this case, Fig.12 As shown, it is only necessary to increase the number of injection pumps 14 or infusion pumps 13. Of course, since a surgery may also require the acquisition of multiple target concentrations of liquid medicine, at this time, a host device 15 is required to control multiple injection pumps 14 or infusion pumps 13 to work, so as to meet the needs of obtaining liquid medicines of multiple target concentrations.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
