Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to an intelligent nebulized drug delivery control method. Background Technology

[0002] A medical nebulizer is a device that converts liquid medication into an aerosol for inhalation through the mouth or nose. It generally consists of a main unit and nebulizing accessories. Currently, there are three main types of medical nebulizers on the market: The first type is the ultrasonic nebulizer, which uses ultrasound to atomize the medication. However, it has drawbacks such as low aerosol output efficiency, medication temperature rise affecting the stability of some drugs, and larger aerosol particles that are not effective in treating lower respiratory tract diseases. The second type is the compression nebulizer, which uses the Venturi jet principle to atomize the medication. However, it also has disadvantages such as large size, high noise, upward atomization only, and medication temperature rise affecting the stability of some drugs. The third type is the mesh nebulizer, which uses high-frequency vibration of a piezoelectric ceramic plate to force the medication through tiny mesh openings to produce aerosol particles. The diameter of the mesh openings directly determines the size of the aerosol particles. Compared to the first two types, mesh nebulizers have advantages such as higher atomization efficiency, less residual medication, lower noise, and smaller size and lighter weight, while also reducing the impact of heat generated by ultrasonic vibration on the medication.

Attached Figure Description

[0046] Figure 1 This is a flowchart illustrating an embodiment of the intelligent nebulization dosage control method provided in this application. Detailed Implementation

[0047] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] A medical nebulizer is a device that converts liquid medication into an aerosol for inhalation through the mouth or nose. It generally consists of a main unit and nebulizing accessories. For mesh nebulizers, intelligent dosage control is extremely important.

[0049] This invention relates to an intelligent nebulizer dosage control method, applied to a mesh nebulizer. The mesh nebulizer includes at least one drug reservoir, each storing one type of drug. The method includes: determining the effective nebulization time and drug ratio; after the mesh nebulizer starts operating, controlling the flow of the drug stored in the drug reservoir into the nebulizer plate according to the drug ratio to output atomized particles; recording the actual nebulization time based on the concentration of the atomized particles; and controlling the mesh nebulizer to stop operating when the actual nebulization time reaches the effective nebulization time. The method provided by this invention, after the mesh nebulizer starts operating, controls the flow of the drug stored in the drug reservoir into the nebulizer plate according to the drug ratio to output atomized particles; records the actual nebulization time based on the concentration of the atomized particles; and controls the mesh nebulizer to stop operating when the actual nebulization time reaches the effective nebulization time, thus achieving intelligent dosage control for the mesh nebulizer.

[0050] This embodiment provides an intelligent nebulized drug delivery control method applied to a mesh nebulizer. The mesh nebulizer includes at least one drug reservoir, with each reservoir storing one type of drug. Additionally, the mesh nebulizer includes an atomizing cup, which is connected to all drug reservoirs.

[0051] In practical applications, the nebulized medication can be a single solution, such as budesonide suspension for inhalation, which needs to be mixed with a solvent (such as saline) before inhalation. Alternatively, multiple solutions can be used, such as a mixture of dexamethasone and antibiotics. However, existing mesh nebulizers only have one nebulizing cup and no medication storage device. This requires users to mix two or more liquids according to a specific ratio, pour the mixture into the nebulizing cup, and then nebulize it. This increases the complexity of operation for users, the possibility of user error, and consequently, the safety risks.

[0052] The mesh nebulizer described in this embodiment has at least one medication reservoir, and each reservoir stores one type of medication for nebulization. This eliminates the need for users to mix multiple medications; they simply select the appropriate number of reservoirs based on the type of medication, pouring each medication into one reservoir. The method provided in this embodiment automatically mixes the medications, and the mixed liquid flows into the nebulizer cup for atomization. This mesh nebulizer reduces user complexity, minimizes the possibility of misoperation, and lowers safety risks.

[0053] See Figure 1 The intelligent nebulization dosage control method provided in this embodiment is implemented as follows:

[0054] S101, determine the effective nebulization time and drug solution ratio.

[0055] The drug concentration ratio can be obtained based on the prescription. There are several ways to obtain it, such as the user inputting the drug concentration ratio; or establishing a communication connection with the doctor's operating system, scanning the user's identifier (such as ID), and directly reading the user's prescription based on the identifier; or scanning the prescription provided by the user (such as taking a picture), parsing the prescription to obtain the drug concentration ratio.

[0056] The effective atomization time can be determined using the following method:

[0057] 1. Obtain patient information, prescription information, and the unit output volume Q of the mesh nebulizer. D .

[0058] There are several methods for obtaining patient and prescription information. For example, users can input patient and prescription information; a communication connection can be established with the doctor's operating system, and after scanning the user's identifier (such as ID), the patient and prescription information can be read directly based on the identifier; or the prescription provided by the user can be scanned (such as by taking a picture) and the prescription can be parsed to obtain the patient and prescription information.

[0059] Other patient information includes age and gender.

[0060] Mesh atomizer atomization particle output Q D This is determined based on the currently selected particle output of the mesh atomizer. Mesh atomizers have controls for adjusting the particle output (such as sliders, speed settings, etc.), which users can adjust according to their needs, such as high, medium, or low. Mesh atomizers are manufactured with the corresponding particle output for each speed setting published at the factory. This step detects the currently selected speed setting and then calculates the particle output Q based on this correspondence. D .

[0061] 2. Based on the pre-set correspondence between patient information, prescription information, and total output of nebulized particles, determine the total output of nebulized particles Q corresponding to the patient information and prescription information. A .

[0062] The amount of nebulized air needed varies depending on age, gender, and medical condition; for example, it differs between adults and children, and between men and women.

[0063] A pre-defined mapping table is created based on age, gender, and condition, corresponding to patient information, prescription information, and total nebulized particle output. This table is stored. During this step, the system uses this mapping table to find the total nebulized particle output Q corresponding to the patient information and prescription information obtained in step 1. A .

[0064] 3. Based on the pre-set correspondence between patient information and the nebulized particle unit output threshold, determine the nebulized particle unit output threshold Q0 corresponding to the patient information.

[0065] The required amount of nebulized particles inhaled per unit of time varies depending on age and gender. Children, due to their smaller lung capacity, inhale relatively fewer nebulized particles per unit of time. However, if adults inhale the same number of nebulized particles per unit of time as children, the medication's efficacy will be affected due to insufficient particle intake.

[0066] Therefore, a suggested minimum output value for nebulized particles per unit is pre-calculated based on age and gender, forming a table that maps patient information to nebulized particle output value thresholds. During this step, the suggested nebulized particle output value corresponding to the patient information obtained in step 1 is retrieved using this mapping; this value is the nebulized particle output value threshold Q0.

[0067] 4. If Then determine the effective atomization time. like Then determine the effective atomization time.

[0068] Here, α is the age coefficient corresponding to the patient's information, which is a pre-set empirical value, 0 < α < 1. This is the floor function.

[0069] like This indicates the unit output quantity Q of atomized particles corresponding to the currently selected gear level. D If the output quantity per unit volume of atomized particles is higher than or equal to the threshold Q0, and the requirement is met, then its effective atomization time is... That is, the ratio of the total output of atomized particles to the unit output of atomized particles.

[0070] like This indicates the unit output quantity Q of atomized particles corresponding to the currently selected gear level. D The output volume per unit volume (Q0) is lower than the threshold value (Q0) for nebulized particles, which does not meet the requirements. Therefore, the nebulization time will be prolonged to ensure sufficient medication is inhaled. On the basis of, add

[0071] This indicates the multiple by which the user's currently selected atomized particle output is lower than the threshold for atomized particle output. The higher the multiple, the longer the duration. However, different ages have different tolerances for the duration. For example, infants have difficulty maintaining the required posture for a long time. The duration is adjusted by a predefined α to better suit each user and improve the atomization experience while ensuring efficacy.

[0072] S102, after the mesh nebulizer is working, controls the flow of the medicine stored in the medicine storage device into the nebulizer plate according to the medicine ratio so as to output atomized particles.

[0073] After obtaining the relevant information in step S101, the mesh atomizer can be turned on automatically, that is, the mesh atomizer can be automatically controlled to work. It can also monitor whether the user turns on the mesh atomizer. When the user turns on the mesh atomizer, the mesh atomizer will work.

[0074] Since the mesh nebulizer includes an atomizing cup, which is connected to all the medication storage containers, the implementation process of this step is as follows:

[0075] 1. Determine the outflow rate of the medicine in each medicine storage container according to the medicine solution ratio.

[0076] 2. Control the flow rate of each medicine storage device to deliver medicine to the atomizing cup.

[0077] 3. Flow the liquid in the atomizing cup into the atomizing plate.

[0078] Before implementing the intelligent nebulization dosage control method of this embodiment, the user will select the corresponding number of drug storage devices according to the type of drug solution, and pour each type of drug solution into a unique drug storage device. At the same time, the user can inform (e.g., by input, selection, or by adding a scanning device to the drug storage device to obtain drug information by scanning the drug packaging) the name of the drug solution poured into the drug storage device.

[0079] During this step, the flow rate of the medication from the corresponding medication reservoir is determined based on the medication ratio. While the flow rates differ, the flow time remains the same, and the medication reservoirs are identical (i.e., identical material, cross-sectional area, height, etc.). This results in varying flow rates of the medication, ensuring that the ratio of the mixed liquid flowing into the nebulizer cup meets the specified medication ratio.

[0080] For example, the medication solution includes medication solution 1 and physiological saline, with a ratio of medication solution 1: physiological saline = 2:1. If the outflow rate of the medication reservoir containing physiological saline is v, then the outflow rate of the medication reservoir containing medication solution 1 is 2v. Consequently, the ratio of medication solution 1 to physiological saline in the mixed liquid flowing into the nebulizer cup is 2:1. This allows the medication needs to be met without requiring the user to prepare the medication solution.

[0081] S103, record the actual atomization time based on the concentration of atomized particles.

[0082] For example, S103 can be achieved through the following steps:

[0083] S103-1, Set the timer.

[0084] S103-2, real-time monitoring of the concentration of atomized particles.

[0085] S103-3 If the concentration is not less than the preset concentration threshold, the timer starts timing, and the timing result of the timer is the actual atomization time.

[0086] Existing nebulization solutions use a timer that is continuously activated. This presents a problem: if the atomized particle concentration is insufficient, there is no nebulization effect, but the timer continues. For the user, this period does not provide any nebulization effect, effectively shortening the effective duration and thus affecting the medication's efficacy. This proposed solution's timer only activates after the atomized particle concentration reaches the required level, ensuring the effective nebulization duration meets the required standards and guaranteeing the nebulization effect.

[0087] In addition, to achieve a better atomization effect, the specific implementation process for starting the timer if the concentration is not less than a preset concentration threshold can also be as follows: if the concentration is not less than the preset concentration threshold, and the duration of the concentration being greater than the preset concentration threshold is greater than... Then the timer starts counting.

[0088] In other words, timing doesn't start immediately when the concentration of atomized particles reaches a threshold. Instead, timing begins when the duration of the atomized particle concentration meeting a certain value. Timing is only started when the concentration occasionally reaches the threshold and then falls below it, but timing has already started when the threshold is reached, which would cause inaccurate atomization time.

[0089] Where T0 is the rated output of the mesh atomizer from the start until the desired atomized particle output Q is achieved. D The required duration for the minimum concentration is determined at the factory of the mesh atomizer. This value can be obtained by testing the mesh atomizer, specifically the time from the start of the atomization process until the unit output of atomized particles is Q. D Duration.

[0090] i is the identifier for the liquid medicine storage device, H i R represents the height of the medicine in the i-th medicine storage unit. i Q represents the ratio of the medicine stored in the i-th medicine storage device to the medicine concentration. D β is the unit output of atomized particles for a mesh atomizer. t The preset time ratio is a relatively small value.

[0091] S is the cross-sectional area of ​​the drug solution storage container, then H i *S represents the total amount of medicine in the i-th medicine storage device. This represents the actual duration of drug consumption in the i-th drug storage device.

[0092] This represents the shortest actual consumption time among all medications, and also the longest possible nebulization process, as exceeding this time would terminate nebulization due to the lack of any medication. If this nebulization time is greater than or equal to the preset minimum value, then the duration is based on the theoretical achievement of Q.D The duration (i.e., T0) is determined by the time the concentration is greater than the preset concentration threshold until T0*β is reached. t You can start timing at that point. If this nebulization time is less than the preset minimum value, it means there is very little medication and it's impossible to reach T0*β. t Only need to reach It can then be used to keep track of time.

[0093] To ensure that the user achieves the effective nebulization duration during this nebulization process, the timer monitors whether the conditions for pausing the timer are met. If they are, the timer will pause until the conditions are met again. If the conditions for pausing the timer are not met for the first time after the initial pausing, the timer will resume. The timer will continue to monitor whether the conditions for pausing the timer are met, thus ensuring that the time recorded by the timer is the actual nebulization duration, excluding the time without medication effect.

[0094] In other words, after the timer starts counting, the process includes: if the conditions for pausing the timer are met, then pausing the timer. If the conditions for pausing the timer are not met for the first time, then the timer resumes counting.

[0095] The conditions for pausing the timer can be one or more of the following:

[0096] The timing is paused when the concentration of the currently monitored atomized particles is lower than a preset concentration threshold. In other words, after the timer starts counting, if the concentration of the currently monitored atomized particles is found to be lower than the preset concentration threshold, the timing stops and continues until the concentration of the currently monitored atomized particles is again at or above the preset concentration threshold, thus ensuring the user has sufficient time to effectively inhale the atomized particles.

[0097] The timing is paused when 90 - γ > 5. Here, γ is the tilt angle between the atomizing cup and the ground, and γ ≤ 90°. This means that after the mesh atomizer starts working, the tilt angle γ between the atomizing cup and the ground is monitored in real time. The mesh atomizer needs to be perpendicular to the ground during operation. If 90 - γ > 5, it is considered that the mesh atomizer has not met the vertical requirement, which may result in poor contact between the atomizer and the user, causing atomized particles to flow into the atmosphere, or poor contact between the liquid mixture in the atomizing cup and the atomizing plate, affecting the output of atomized particles. After the timer starts counting, if 90 - γ > 5, the timing stops and resumes only when 90 - γ ≤ 5, ensuring the user has sufficient time to effectively inhale atomized particles.

[0098] In practical implementation, the scheme of timing when 90-γ≤5 can also result in the concentration not meeting the standard. Therefore, in addition to the scheme of timing when 90-γ≤5, this embodiment also provides a preferred scheme, namely, 90-γ≤5, and the current concentration of the monitored atomized particles is less than When this condition is met, the timing is also paused. Specifically, the timing is paused when 90 - γ ≤ 5 and the current concentration of the monitored atomized particles is less than [a certain value].

[0099] Among them, C down This is a pre-set lower limit of the standard concentration. It ensures both the quality of the user's inhalation and the quality of the atomized particles output by the nebulizer.

[0100] S104: When the actual atomization time reaches the effective atomization time, the control mesh atomizer stops working.

[0101] When the actual atomization time reaches the effective atomization time, it indicates that the atomization task has ended, and therefore the control mesh atomizer stops working.

[0102] In addition, after the mesh nebulizer starts working, it will monitor the medication status in each medication storage device in real time. If any medication storage device fails to meet the preset minimum conditions, the mesh nebulizer will stop working even if the actual nebulization time has not reached the effective nebulization time, thus preventing the mesh nebulizer from working ineffectively. That is, after the mesh nebulizer starts working, if the medication stored in any medication storage device does not meet the preset minimum conditions, the mesh nebulizer will stop working.

[0103] The method proposed in this proposal can be controlled and executed by a central control module, which can be installed inside the mesh atomizer. Additionally, the mesh atomizer will also house storage devices, a communication module, a power supply module, a controller, a timer, and various sensors.

[0104] Storage device for storing patient information, prescription information, and the correspondence between total nebulized particle output; the correspondence between patient information and nebulized particle unit output threshold; various coefficients (such as the age coefficient corresponding to patient information); various thresholds (such as concentration thresholds); and the rated nebulized particle unit output Q from start to finish. D Requirements include the duration of minimum concentration, time ratio, and lower limit of standard concentration.

[0105] The communication module can be a wireless communication module and / or a wired communication module, used to establish a communication connection with the doctor's work system, etc.

[0106] The power supply module is used to supply power to the mesh atomizer.

[0107] A controller can be installed on one or more components of a mesh nebulizer for controlling its operation. For example, a controller can be installed on each medication reservoir to control the outflow rate of the liquid in the reservoir.

[0108] A timer is used to record the actual atomization time.

[0109] Various sensors are included, such as: scanning devices for scanning prescriptions and drug packaging provided by users; image acquisition devices for acquiring images of prescriptions and drug packaging provided by users; atomized particle concentration sensors for real-time acquisition of the concentration of atomized particles; liquid level sensors for detecting the liquid level in each medication storage container; and angle sensors for real-time acquisition of the tilt angle between the atomizing cup and the ground.
