Description

Technical Field

[0001] The present invention belongs to the technical field of intestinal fluid preparation, and more specifically, relates to a device for preparing anorectal disease enema fluid that can be stored at a constant temperature. Background Art

[0002] In the treatment of anorectal diseases, enema therapy is a common and effective treatment method. The enema solution requires the drug ingredients to be evenly mixed and the temperature to be constant, so as to ensure the stable efficacy of the drug and promote patient recovery.

[0003] Currently, the commonly used enema solution mixing devices on the market have exposed numerous problems in practical applications. Regarding mixing effectiveness, traditional devices only feature simple stirring mechanisms, which are unable to fully mix multiple ingredients. For example, when preparing enema solutions containing solid drug particles and liquid components, the solid particles are difficult to evenly disperse and are prone to precipitation, resulting in inconsistent drug concentrations in different parts of the enema solution. During the mixing process, traditional devices also experience significant liquid fluctuations due to their stirring method, which can easily lead to deviations in liquid level data in such a fluctuating environment.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] 1. The stirring motor drives the rotating shaft and multiple groups of stirring blades arranged obliquely upward on the circumference to rotate, stirring the inner cavity liquid to the outer cavity, realizing liquid circulation and preliminary mixing. The two groups of homogenizing valves are connected by a high-pressure pump through the first two-way pipe to spray the liquid at high speed. The shear force and impact force of the high-speed jet are used to break up large particles and liquid masses, thereby enhancing the mixing effect.

The rotating shaft 204 extends into the inner cavity. The peripheral side of the rotating shaft 204 is connected to multiple groups of stirring blades 201. These stirring blades 201 are driven by the stirring motor 203 to stir the liquid in the inner cavity to the outer cavity, thereby realizing the circulation and preliminary mixing of the liquid. This circulation mixing mode helps to break the static state inside the liquid and promote the preliminary contact and fusion between different components. The top of the mixing tank 101 is also provided with An injection pump 103 is connected to a liquid extraction tube 104 on one side of which a flow sensor 105 is installed.

When the high-pressure pump 205 is working, the liquid can be delivered to the homogenizing valve 202 at a higher pressure through the two sets of homogenizing valves 202.

When the air compressor 211 is working, it can inflate the airbag 208 to expand the airbag 208; and when the airbag 208 is deflated, its contraction process will drive the surrounding liquid to vibrate. The shock wave is generated by the airbag 208, which prevents precipitation at the bottom of the mixed liquid and the clogging of the two sets of through holes at the bottom of the inner cavity, thereby improving the stability of the operation. The setting of the buffering and shock-absorbing pad 210 can, on the one hand, play a buffering role during the expansion and contraction of the airbag 208, and protect the bottom of the outer cavity from being affected by excessive impact force.

The reflective layer 409 can reflect the light emitted by the ultraviolet lamp group 401 and cooperate with the light sensor 402 to obtain the original detection parameters.

[0072] Please refer to Figure 10 As shown, the compensation module corrects the liquid level data information by the following steps:

[0073] S1: obtaining original detection parameters in the mixing chamber based on the liquid level component, collecting historical data, and establishing a standard liquid level library based on the historical data, wherein the standard liquid level library includes a liquid level-parameter correspondence table;

[0074] Specifically, it includes retrieving historical data accumulated during the past operation of the dispensing device, wherein the historical data includes liquid level parameters and detection parameters corresponding to each liquid level parameter obtained under the corresponding liquid level state;

[0075] Furthermore, the liquid level parameters are arranged in ascending or descending order, and then the data group with the difference between adjacent liquid level parameters in the range of [50,100] is selected. The liquid level changes in this range can reflect the common liquid level changes in the mixing process, but it is not difficult to capture effective features due to too small liquid level changes, nor is it too discrete due to too large liquid level changes.

[0076] From the screened data set, the detection parameters corresponding to each liquid level parameter are extracted, and these liquid level parameters and their corresponding detection parameters are integrated to construct a liquid level-parameter correspondence table as the data basis for subsequent analysis.

[0077] For example, the historical data can also be obtained through experiments, such as filling the mixing device with enema liquid to obtain liquid level parameters and detection parameters once, then draining the enema liquid with a liquid level parameter difference within the range of [50, 100], and then obtaining liquid level parameters and detection parameters again until the mixing device is emptied, thereby obtaining a liquid level-parameter correspondence table that does not require filtering;

[0078] To put it another way, an empty mixing device can be selected, and then enema liquid with liquid level parameter differences within the range of [50,100] can be added in sequence, and the liquid level parameters and detection parameters can be performed after each addition until the mixing device is full. A liquid level-parameter correspondence table can also be obtained without screening.

[0079] S2: Perform similarity matching based on the liquid level-parameter correspondence table and the original detection parameters to obtain the standard liquid level and standard detection parameters with the highest similarity;

[0080] Specifically, the matching operation includes the following steps:

[0081] S2-1: extracting standard detection parameters from the liquid level-parameter correspondence table, and then extracting features from the standard detection parameters and the original detection parameters, respectively. The features are one or more of light propagation time, light wavelength change, and light angle;

[0082] Specifically, all standard detection parameters are extracted from the liquid level-parameter correspondence table. Then, feature extraction is performed based on the features detectable by the optical sensor 402 from the standard detection parameters and the original detection parameters, such as light intensity, light propagation time, light wavelength change, and light angle. These features can reflect the change of the liquid level from different dimensions. For example, the change of light intensity is related to the concentration distribution of the liquid, the change of light propagation time is related to the high and low changes of the liquid level, the change of light wavelength is related to the fluctuation of the liquid surface, and the light angle is related to the amplitude of the liquid surface fluctuation. Here, the light intensity is only related to the concentration of the liquid, and the concentration of the liquid is irrelevant to the purpose of correcting the deviation of liquid level data information in a liquid fluctuation environment to be achieved by this application. Although the detected light intensity value will also show a downward trend when the liquid level is higher, at the same liquid level, the change of concentration alone will also cause a corresponding change in the light intensity value. Therefore, although the optical sensor 402 can detect light intensity, the reference to the light intensity feature is not considered in this application.

[0083] S2-2: Calculate the similarity between the extracted features of the standard detection parameters and the extracted features of the original detection parameters and perform normalization processing to obtain the comprehensive similarity corresponding to each standard liquid level;

[0084] Specifically, the Euclidean distance is used to calculate the light propagation time and the change in light wavelength. The Euclidean distance is the real distance between two points in a dimensional space. Physical quantities such as light propagation time and light wavelength change can be regarded as vectors in a dimensional space. Taking the light propagation time as an example, we can have:

[0085] ;

[0086] in, They represent the light propagation time measured at n time gradients in the original detection parameters; They represent the light propagation time in the standard detection parameters under n time gradients corresponding to the original detection parameters; The Euclidean distance between the original detection parameter light propagation time and the standard detection parameter light propagation time is used to directly measure the geometric distance between two vectors in space. The result intuitively reflects the overall difference between the corresponding values ​​of the original detection parameter and the standard detection parameter at each time gradient. The smaller the distance, the more similar the two are, and vice versa. In addition, in a physical sense, for physical quantities with clear numerical values ​​and additivity, such as light propagation time and light wavelength change, the Euclidean distance can well align with our intuitive understanding of "difference", that is, the actual numerical difference.

[0087] Furthermore, n represents the interval time for updating the liquid level data information, such as 1 second, 2 seconds, etc.; and the number of raw detection parameter characteristics such as light propagation time, light wavelength change, and light angle obtained depends on the detection frequency of the optical sensor 402, such as obtaining the raw detection parameters once per second, obtaining the raw detection parameters twice per second, etc.;

[0088] Understandably, It can also represent the light wavelength change value measured at n time gradients in the original detection parameters, and the corresponding They are respectively expressed as the light wavelength change values ​​under n time gradients corresponding to the original detection parameters in the standard detection parameters, thereby obtaining the similarity value of the light wavelength change;

[0089] For example, in the present application, the electric slider 404 can move on the annular guide rail 403 to drive the light sensor 402 and the ultraviolet lamp assembly 401 to move along the annular path. During the movement, the light sensor 402 in the liquid level detection assembly is used to collect data on the enema liquid level at different positions in the preparation cavity to obtain the original liquid level data. Furthermore, eight scales can be equally divided and established on the annular guide rail 403. When the light sensor 402 moves along the annular path and reaches one of the scales, the original detection parameter characteristics are obtained.

[0090] Cosine similarity is used to calculate the light angle. The light angle mainly focuses on the direction information. The cosine similarity focuses more on measuring the directional consistency of the two vectors and is relatively less sensitive to the length of the vector. This is very suitable for comparing light angles because, in the case of liquid level fluctuations, more attention is paid to whether the propagation direction of light is consistent rather than the difference in specific angle values. For example, if the overall light angle is enlarged or reduced by a certain multiple, the cosine similarity value will not change as long as the direction remains unchanged. The value range of cosine similarity is between -1 and 1. The closer the value is to 1, the more similar the directions of the light angles are; the closer the value is to -1, the opposite directions are; when the value is 0, it means that the two are perpendicular to each other and the similarity is the lowest, which is convenient for intuitive judgment and comparison of the similarity between different light angles.

[0091] Furthermore, the similarity of each feature is normalized to obtain the comprehensive similarity; these different similarity values ​​are unified into the same numerical range to facilitate comparison and comprehensive analysis. For example, the similarity value calculated by Euclidean distance may be in a larger numerical range, while the value range of cosine similarity is [-1, 1]. After normalization, they can all be mapped to a standard interval such as [0, 1]. Since the value of cosine similarity of light angle is between [-1, 1], it needs to be normalized. Through this linear transformation, the minimum value -1 is mapped to 0, the maximum value 1 is mapped to 1, and the intermediate values ​​are also linearly transformed accordingly, so that they are in the same numerical range as other normalized similarity values ​​for easy calculation;

[0092] S2-3: Select the standard liquid level parameter with the highest comprehensive similarity and its corresponding standard detection parameter from the liquid level-parameter correspondence table.

[0093] Specifically, the data in the liquid level-parameter correspondence table are arranged according to the size of the comprehensive similarity, and a group of data with the greatest comprehensive similarity is selected, as well as the standard liquid level parameter with the greatest comprehensive similarity and its corresponding standard detection parameter;

[0094] S3: Calculate the deviation ratio between the standard detection parameter with the highest similarity and the original detection parameter;

[0095] Specifically, the deviation ratio calculation includes:

[0096] S3-1: Obtain the standard detection parameter with the highest similarity, and extract features from the standard detection parameter with the highest similarity and the original detection parameter respectively;

[0097] Specifically, the standard detection parameter with the highest similarity obtained in the similarity matching is obtained, and the features selected in step S2-1 are extracted again from the standard detection parameter and the original detection parameter to ensure the consistency of the calculation;

[0098] S3-2: Calculate the deviation ratio of each extracted feature respectively;

[0099] Specifically, for each extracted feature, including:

[0100] The light propagation time, light wavelength change and light angle of the original detection parameters, and the light propagation time, light wavelength change and light angle of the corresponding standard detection parameters, and the deviation ratio of the corresponding light propagation time, light wavelength change and light angle is calculated respectively;

[0101] Furthermore, by calculating the deviation ratio, the difference between the original detection parameters and the standard detection parameters can be quantified. For example, although the standard liquid level parameter with the highest similarity is obtained through the matching operation, the standard liquid level parameter cannot directly represent the actual liquid level data information. Therefore, the standard liquid level parameter needs to be adjusted based on the deviation ratio to obtain the actual liquid level data information.

[0102] S3-3: Set weights for each extracted feature, and perform weighted summation on each deviation ratio to obtain a correction value.

[0103] Specifically, weight coefficients are set for each feature, such as light propagation time, light wavelength change, and light angle, and then the deviation ratio is weighted. For example, light propagation time can intuitively illustrate the liquid level height. However, when the liquid level fluctuates, the liquid level will fluctuate. Light wavelength change and light angle can respectively reflect the liquid level fluctuation and fluctuation amplitude.

[0104] It is understandable that when the mixing device is mixing, the fluctuation of the liquid level will tend to be within a certain range, and the height of the liquid level will not have a significant impact on the fluctuation of the liquid level. Therefore, the light propagation time characteristic tends to have a higher weight coefficient, while the light wavelength change and light angle tend to have a lower weight coefficient;

[0105] For example, when the device mixes 10L of liquid or 20L of liquid, the liquids are mixed under the action of the mixing structure, and the liquid levels fluctuate. However, the fluctuation of the liquid level of the 10L liquid is not significantly different from that of the 20L liquid.

[0106] Furthermore, the selection of weight coefficients can be achieved by detecting a single feature such as light propagation time, light wavelength change, or light angle. Specifically, multiple groups of samples are set to obtain original detection parameters, from which a certain feature such as light propagation time, light wavelength change, or light angle is extracted. Standard detection parameters containing only this feature are extracted from the liquid level-parameter correspondence table. These sample data are independently detected and compared with the standard detection parameters in the liquid level-parameter correspondence table. The error between the two is calculated. Based on the calculated error and the degree of attention paid to different features in actual application scenarios, a weight coefficient is determined for each feature. For example, if in the liquid level detection scenario, light propagation time is most sensitive to liquid level changes, and its error has a greater impact on the liquid level data information when compared with the standard sample library, then a larger weight coefficient can be assigned to the light propagation time.

[0107] S4: Correct the standard liquid level with the highest similarity based on the deviation ratio calculation;

[0108] Specifically, based on the deviation ratio calculated in step S3, the standard liquid level with the highest similarity selected in step S2 is corrected. For example, if the correction value is a positive number, it indicates that the original detection parameters are larger than the standard detection parameters, which may mean that the actual liquid level is higher than the standard liquid level. The standard liquid level can be corrected by the method of standard liquid level × (1 + correction value); if the correction value is a negative number, it is corrected by the method of standard liquid level × (1-|correction value|).

[0109] S5: Obtain the actual liquid level based on the correction operation.

[0110] Through the above correction operation, a value that can reflect the actual liquid level in the mixing chamber is obtained. This value provides accurate liquid level data information for subsequent operations of the mixing device, such as mixing ratio adjustment and liquid level control.
