According to a preferred embodiment, the monitoring module 100 of the present invention can acquire status information of the liquid medicine dropping in the morse dropper in real time through a camera imaging technology. Preferably, the monitoring module 100 can acquire the state information of different liquid drops dropping at different time periods through the principle of image imaging technology. In particular, the monitoring module 100 may be provided with corresponding photographic and/or video equipment to acquire image information of the droplets. Preferably, the liquid state information collected by the monitoring module 100 includes a specific form of the liquid drop, a vibration form when the liquid drop falls on the liquid medicine surface, a fluctuation condition of the liquid medicine surface, a liquid state of an inner wall surface of the morse dropper, and the like, and records a corresponding time point when the liquid drop falls. Preferably, the image of the drop of the liquid drop collected by the monitoring module 100 may also be uploaded to a cloud server for storage, so that the medical staff can visually check the drop form of the liquid drop in the time-sharing state.
Further, the image acquisition and imaging process of the monitoring module 100 is different from the imaging method in the general industry for detecting the flow rate of liquid. Specifically, there may be a possibility that the light is stronger or weaker in the environment where the patient or the medical staff is located, and the monitoring module 100 performs light adjustment based on the light intensity of the environment in the process of collecting the droplet state and imaging, so as to improve the definition of the imaging graph.
Secondly, in the process of dropping the liquid medicine, residual liquid is formed on the inner wall surface of the morse dropper, the residual liquid can form interference when the monitoring module 100 acquires the liquid drop image, the monitoring module 100 can identify the position relation between the liquid drop to be imaged which is positioned in the middle of the cavity of the morse dropper and is not in contact with the inner wall surface and the residual liquid drop on the inner wall surface through the set hardware program and/or software function, and/or the real-time motion states of the liquid drops in two different states can distinguish the liquid drop to be imaged or the residual liquid drop, and in the imaging process, the monitoring module 100 reduces the proportion and the definition of the residual liquid drop in the final formed image based on the distinguishing process so as to furthest keep the image of the liquid drop to be imaged.
In addition, when the monitoring module 100 performs image acquisition and imaging, a plane where the morse dropper is located often has a patient or a medical staff as an image background, so that interference can be caused to an imaging process and a final image display effect, and the monitoring module 100 can redraw and/or eliminate the background of the space where the morse dropper is located based on factors such as color elements, color intensity and light definition of the space background where the morse dropper is located. Preferably, the monitoring module 100 may redraw the background color of the space where the morse dropper is located into white color for easy image analysis and recognition, or directly virtualize the background color, and only keep the image of the droplet to be imaged, so as to provide a clearer and more intuitive image of the state of the droplet when the droplet is dropped. Most importantly, when the monitoring module 100 acquires an image, if the morse dropper is shaken to be in a tilted state due to human factors or force ineffectiveness, the acquired image may have a non-ideal standard image.
According to a preferred embodiment, due to the difference in physicochemical properties of the medical fluids, the density or viscosity of the medical fluid, the degree of suspension, and the ease of decomposition of a portion of the medical fluid may interfere with the imaging process of the monitoring module 100. Particularly, as part of the medicines have the property of visible light decomposition, a light-proof infusion set needs to be selected; on the other hand, the density, viscosity, degree of suspension, etc. of the liquid medicine affect the pixels of the final image. Preferably, an opaque liquid such as plasma may activate a corresponding fill light adjusting unit in the monitoring module 100 to increase the brightness of the monitoring area so as to make the final imaging result of the monitoring module 100 clearer. Therefore, it is critical how to acquire an idealized image by setting a reasonable pixel threshold and calculate the drop velocity based on the image.
According to a preferred embodiment, the image recognition and calculation method based on the image acquisition of the monitoring module 100:
the first step is as follows: the first pixel threshold value P is preset by the operation module 400 according to the physico-chemical properties of the liquid medicine 1 And a second pixel threshold value P 2 ；
The second step is that: the monitoring module 100 scans the identification code on the infusion bag to obtain the liquid medicine information, the corresponding infusion apparatus specification and the first pixel threshold value P 1 And a second pixel threshold value P 2 ；
The third step: the monitoring module 100 reads droplet landing images of each frame rate frequency band in a Mohs' dropper based on a preset image acquisition time interval delta t, and performs gray level processing on the images, wherein 0.05s is made of t-cloth 0.1s;
the fourth step: performing gray difference processing on the droplet landing images in the adjacent frame rate frequency bands after the graying processing based on a difference method to obtain a difference image;
the fifth step: threshold based binarizationThe process further converts the differential image to a black-and-white image, wherein the total black image pixel value in the black-and-white image is labeled R b The total pixel value of the white map is then labeled R w ；
And a sixth step: r is to be w And a first pixel threshold value P 1 And a second pixel threshold value P 2 Making a difference comparison, wherein if R w <P 1 If the liquid level of the liquid medicine in the Mohs dropper does not vibrate, the system judges that no liquid drop drops into the liquid medicine; r w >P 2 The system determines that an anomaly has occurred in the monitoring process (e.g., liquid level jitter in the mohs' dropper is out of the expected range); when the two situations occur, the image acquisition result is not processed, but the third step is returned to continue to read the droplet dropping images of each frame rate frequency band in the Mohs dropper, and in addition, in order to avoid interference, after the specific dropping behavior meeting the threshold is determined, whether obvious pixel change exists in a certain middle part at the upstream is additionally verified to determine that the actual dropping exists, but not the interference pixels (such as image jitter and the like);
the seventh step: if P 1 <R w <P 2 Then, the system judges that the liquid medicine surface in the Mohs' dropper vibrates, namely liquid drops drop into the liquid medicine, records the frame rate frequency band of the image of the drop, and obtains the frame number difference delta f by making a difference with the frame rate frequency band of the image recorded last time, and calculates the average dropping speed of the liquid drops according to the image acquisition time interval delta t and the frame number difference delta f:

preferably, the liquid to be input can be classified into transparent and opaque categories according to the physical properties of the liquid, and further, the transparent and opaque categories can be further subdivided into low density, medium density and high density. Specifically, the medical staff may preset different first pixel threshold values P based on the physicochemical properties of the different types of liquids 1 And a second pixel threshold value P 2 . Because the bases different from each other are determined according to the liquid medicine to be infusedThe threshold value of the pixel (for example, P is greater than P ', and P may be less than P' if the black and white are inverted) is determined, so that when the processing module 200 processes the droplet landing image into a black and white image in a binarization manner, the liquid and the non-liquid can be determined more accurately, and the operation speed is increased while the interference is eliminated.
Further, when the liquid belongs to the transparent state X, the basic pixel threshold value is set to be P 1 (ii) a When the liquid is in the non-transparent state X', the basic pixel threshold value is set to be P 1 ’。
Preferably, when the liquid is in the transparent low density state X L When (e.g. glucose solution), the first pixel threshold value is set to be P 1L And a second pixel threshold value P 2L (ii) a When the liquid is in a transparent medium density state X m When (e.g., serum), the first pixel threshold value can be set to P 1m And a second pixel threshold value P 2m (ii) a When the liquid is in a transparent high-density state X h Then, the first pixel threshold is set to be P 1h And a second pixel threshold value P 2h ；
Preferably, for a liquid in the opaque state X', when the liquid is in the opaque low density state X L When, the first pixel threshold value is set to be P 1L ' and a second pixel threshold value P 2L '; when the liquid is in the non-transparent medium density state X m When the first pixel threshold is set to P (for example, human serum albumin injection, yellow or green to brown slightly viscous liquid), the first pixel threshold is set to P 1m ' and a second pixel threshold value P 2m '; when the liquid is in a non-transparent high-density state X h When (e.g., plasma), the first pixel threshold value can be set to P 1h ' and a second pixel threshold value P 2h ’。
Preferably, the first pixel threshold value P is 1 And a second pixel threshold value P 2 The method can be obtained by taking a sufficient number of images in advance and performing average value calculation, standard deviation or variance calculation, curve fitting and the like after classification screening.
Preferably, the first pixel threshold value and the second pixel threshold value of different types of liquid can be recorded into the identification code on the infusion bag, so that medical personnel do not need to set the first pixel threshold value and the second pixel threshold value before each detection, but can directly obtain the relevant numerical value by reading the identification code and perform subsequent image acquisition and calculation.
According to a preferred embodiment, the monitoring module 100 will record the image information of the falling drop in the morse dropper at different time intervals while performing the aforementioned operation of eliminating the image interference factor. Preferably, the monitoring module 100 is capable of judging the standard of the acquired image by identifying the position and/or motion state information of each element in the acquired image. Optionally, the monitoring module 100 may send the acquired image to the processing module 200 for parameter calculation after standardized screening, or directly send the beautified and trimmed initial acquired image to the processing module 200 for standardized screening and then for parameter calculation.
According to a preferred embodiment, when the monitoring module 100 collects an image, the time when a droplet drops to the plane of the liquid medicine stored in the morse dropper can be recorded as the initial dropping time, and the specific form of a droplet is collected at the same time, and when a subsequent droplet drops to the same position, the form and the time of the subsequent droplet are recorded. Therefore, the monitoring module 100 can acquire image information of different liquid drops falling at different times, and send the image information to the processing module 200, so as to convert the liquid drop image acquired by the monitoring module 100 and calculate necessary parameters related to the infusion process.
According to a preferred embodiment, an arithmetic and analysis Unit is integrated and/or connected in the processing module 200, and the arithmetic and analysis Unit includes, but is not limited to, a DSP (Digital Signal Processor), an MCU (Micro Control Unit) or an MPU (Micro Processor Unit). Specifically, the processing module 200 can calculate the dropping speed of the liquid drop in the morse dropper in a certain period of time based on the image information of different liquid drops at different times collected by the monitoring module 100, further calculate parameters such as infusion consumption time and infusion amount based on the dropping speed, and recommend an appropriate injection rate, injection time and range of injection amount according to the calculated data and information such as the past medical history, past injection history and personal current state of the patient, and output the information at least through the display module 300. Preferably, the display module 300 may output data such as the adaptive injection rate, the injection time and the range of the injection amount by a color change. For example, if the values of the injection rate, the injection time, and the range of the injection amount of the current patient are within the recommended range, the relevant display value in the display module 300 may be represented by green; if the recommended range is exceeded, the relevant display numerical value can be represented by red; otherwise, if the value is below the recommended range, the associated display value may be represented in blue.
Preferably, in the mobile device carried by the injection management system, an alarm module may be provided. This alarm module accessible sets up the speaker that has buzzing or voice broadcast function and/or can send the warning device of forms such as LED lamp of continuous scintillation and change light to when the infusion parameter that the aforesaid is related to is about to surpass and/or be less than standard range, in time send early warning signal, thereby remind patient or medical personnel in time to adjust the infusion parameter, in order to guarantee patient's life safety.
Further, when calculating the parameters of the drop velocity of the liquid drop, the infusion consumption time, the infusion amount, etc. and giving the adaptive range, many factors need to be considered, such as the size of the morse dropper, the physicochemical properties of the liquid medicine (including but not limited to density, volatility, fluidity, etc.), the diameter of the liquid medicine delivery pipe, the diameter of the injection needle pipe, the type of disease of the patient receiving the injection, the age of the infusion population, etc.
Preferably, some basic parameters can be input and/or set in advance by using the operation module 400 mounted on the mobile terminal. Specifically, the basic parameters include, but are not limited to, the number of the patient's bed, the specifications of the infusion set, the selection of the measurement accuracy, the required calculated values, and the medical service system to be matched. Preferably, these basic parameters will be uploaded to the cloud server so that subsequent healthcare workers can match the basic parameter information based on different calculated values. For example, when a patient in a certain bed takes a certain medicine, the medical staff can measure parameters such as the drop rate, the liquid medicine input time, and the infusion amount of the liquid in the infusion process with certain accuracy when using an infusion set, an infusion tube, and an infusion needle tube of a certain specification.
Preferably, the infusion set may be sized for small infusion sets, common infusion sets (default size, typically 20 drops/ml), large infusion sets, and the like. Furthermore, according to the specification of the infusion apparatus and the condition of a patient, different dropping speed measurement accuracies can be selected. Preferably, the measurement precision can be divided into two types, namely A type (common) and B type (accurate), wherein the A type (common) measurement precision can be used for conventional transfusion, namely the imaging time of 3-5 liquid drops can be selected to calculate the average dropping speed; while the B-type (precision) measurement accuracy is used in infusion applications where the drop rate needs to be strictly controlled, the imaging time of 6-10 drops is usually selected to calculate the average drop rate. Preferably, the required calculation value may include the aforementioned parameters such as dropping speed, infusion consumption time and infusion amount; the medical service system is different App systems and/or cloud servers used by medical staff to manage patients.
According to a preferred embodiment, the processing module 200 needs to perform calibration based on the acquired images when calculating the drop velocity. Specifically, when the first drop of liquid medicine in the morse dropper drops, the monitoring module 100 will start image acquisition. Preferably, the processing module 200 will collect drop images at various times from the beginning to the end of the infusion. However, in the initial stage of dropping the liquid chemical, the drop velocity of the liquid droplet is not uniform, and although the average drop velocity can be calculated based on the drop image of the liquid droplet in this period, this affects the accuracy, authenticity, or the like of the entire data. Therefore, the processing module 200 can omit the drop image in the previous drop uneven time period in the calculation process, and calculate the average dropping speed in the infusion by the drop image in the remaining even drop time period.
According to a preferred embodiment, when calculating the dropping speed, the processing module 200 may determine the average dropping speed based on the dropping image of the drop in the morse dropper collected by the monitoring module 100 and the corresponding time. However, when calculating the time required for infusion and/or the predicted infusion amount based on the drop rate, the size of the morse dropper, the physicochemical properties of the drug solution (including, but not limited to, density, volatility, fluidity, etc.), the diameter of the drug solution delivery tube, the diameter of the injection needle tube, and other parameters are taken into consideration.
Specifically, due to the different types of diseases of patients, the drugs to be injected to the patients are different, and at the same time, the properties of the drugs are different. For example, due to differences in drug density or viscosity, the flow rate in the infusion line is different, which results in different final infusion times into the patient; on the other hand, if part of the drug is decomposed by light, the final input value of the drug in the patient may be less than the expected value if a light-shielding infusion device is not used. Preferably, the operation module 400 may input information related to the flow rate, density, etc. of the drug in advance, so that the processing module 200 can calculate parameters such as the time required for infusion and/or the expected infusion amount, etc. by combining the physicochemical properties of the drug, find the actual infusion time and/or the infusion amount, and find the difference between the actual infusion time and/or the actual infusion amount and the theoretical value, thereby providing the appropriate infusion time and/or infusion amount. When necessary, centralized display and reminding can be carried out on a large screen of the hospital.
According to a preferred embodiment, when the diameter of the drug delivery tube and the diameter of the syringe are different, the final result of the parameters of the processing module 200, such as the time required for infusion and/or the expected infusion amount, is also affected. Specifically, the diameter of the liquid medicine conveying pipe and the diameter of the injection needle pipe influence the flowing speed of the liquid medicine, and further influence the time required for the liquid medicine to flow out of the Morse dropper and be conveyed to the body of a patient through the liquid conveying pipe and/or the amount of the liquid medicine conveyed to the body of the patient in a limited time. Preferably, the operation module 400 may input information about the diameters of the liquid medicine delivery tube and the syringe needle in advance, so that the processing module 200 can calculate the actual infusion time and/or the infusion amount by combining the diameters of the liquid medicine delivery tube and the syringe needle when calculating parameters such as the time required for infusion and/or the predicted infusion amount, and obtain the difference between the actual infusion time and/or the actual infusion amount and the theoretical value, thereby providing the appropriate infusion time and/or the appropriate infusion amount. Preferably, when the calculated parameter such as the time required for infusion and/or the predicted infusion amount differs from the theoretical time required for infusion and/or the predicted infusion amount of the current medical fluid based on the dropping rate, a more ideal time required for infusion and/or the predicted infusion amount may be obtained by arithmetic averaging or weighted averaging.
According to a preferred embodiment, when the processing module 200 further calculates parameters such as infusion consumption time and/or infusion volume based on the dropping speed, and recommends information such as appropriate injection rate, injection time, and injection volume range according to the calculated data, a suitable range is calculated by referring to a patient case formed by preset information such as related to patient disease type, past medical history or injection history, personal recovery status, contraindications, and the like, so as to ensure accuracy and perfection of the recommended parameter range, thereby improving treatment efficiency for the patient, reducing treatment risk, and ensuring life safety of the patient, and further combining the patient case information with the recommended parameter range to form a more detailed personal file, and the personal file can be uploaded to a cloud server to facilitate management of medical staff.
According to a preferred embodiment, each infusion bag of the liquid medicine injected by the patient is provided with the patient identification and the infusion related identification code, and the method can be applied to hospitals with electronic information management systems. Further, medical personnel accessible monitoring module 100 scans the identification code and carries out patient identification, medical personnel will also accomplish daily tour and punch the card when the scanning, and processing module 200 can be with the attendance system of record upload to the hospital, makes things convenient for relevant personnel in time to know each nurse or doctor to the condition of degree of care of patient, thereby be convenient for supervise and/or guide medical personnel to implement the nursing treatment to the patient, and based on the infusion state historical information of attendance record and disease, relevant personnel can synthesize the appraisal to each nurse or doctor's performance condition. Secondly, after the identification code is scanned, the related parameters related to the infusion process calculated by the processing module 200 can be further obtained in the infusion patrol columns of different patients.
Preferably, after scanning the identification code, the processing module 200 can automatically recognize the infusion volume and further calculate the infusion completion time, and by calculating the estimated completion time of infusion for each patient, the display module 300 can inform the medical staff in advance that the infusion is about to be completed, and this function can limit the patient bed number, i.e. the responsibility nurse can limit the own responsibility bed number, and prompt the infusion situation in the handheld device, which includes but is not limited to the information of the current infusion time, the current infusion amount, the estimated infusion time, the estimated infusion amount, and the like. In addition, for the infusion with large capacity, the processing module 200 can summarize the hourly patrol data of the medical staff, and can also calculate the input amount of the patient, so that the nurse can calculate the total input amount of the patient. Preferably, medical personnel can look over infusion information under the infusion patrol column of a plurality of patients on the display module 300 simultaneously, so that the medical personnel can complete one-to-many management, the medical personnel do not need to frequently go to a patient bed for actual measurement and calculation, and the remote patrol can be realized.
According to a preferred embodiment, the injection management system may further upload information related to parameters related to the infusion process and a personal profile formed by the parameters related to the infusion in combination with patient history, which are calculated by the processing module 200, to a cloud server and/or a patient monitoring system in the hospital through a hardware program and/or software installed on the mobile device. Preferably, on the patient supervision system, the medical staff can check the personal file information, the infusion state and the like of different patients at any time. In particular, the patient monitoring system may include basic information of the patient, past medical history, past medication history, allergy history, personal health status, individual physiological contraindications, the type of drug recommended for injection (including physicochemical properties of the drug, adverse reactions), recommended injection period or frequency, injection rate, infusion volume or time, recommended review period, and the like.
According to a preferred embodiment, when looking over the personal file of the patient through the cloud server and/or the patient monitoring system, the medical staff can not only look over the parameter information related to the infusion state of the patient and/or the set basic parameter information, but also judge the accuracy of the injection management system based on the relation between the two parameters. Specifically, under the condition that basic parameters such as the size of the aforementioned morse dropper, physicochemical properties of the liquid medicine (including but not limited to density, volatility, fluidity, etc.), diameter of the liquid medicine delivery pipe, diameter of the injection needle pipe, etc. are fixed, the parameters such as the dropping speed of the liquid drop, the infusion time and the infusion amount calculated by the system should have corresponding values and/or recommended values which are uniquely determined, and when the corresponding values and/or recommended values obtained by the system or no obvious difference and/or trend change is provided under the condition that only at least one of the parameters is changed, the medical staff can consider the accuracy and/or authenticity of the calculated result of the system, namely whether the basic parameters are changed due to other factors, and the calculated corresponding values and/or recommended values still do not change obviously. For example, when the diameter of the infusion tube is increased and/or decreased, the flow speed of the same medical fluid in the tube will be changed, and accordingly, the time required for inputting the same amount of medical fluid will be different, if the estimated infusion time calculated by the system does not change significantly and/or has a reverse trend, which indicates that the calculated value of the system is incorrect, the medical staff may perform troubleshooting by looking at the drop image uploaded by the monitoring module 100, such as whether there is a bubble in the morse dropper and/or the infusion process is affected by factors such as the blockage of the infusion tube, so as to evaluate the accuracy of the system, and meanwhile, the medical staff may troubleshoot the infusion fault based on the basic parameter information and the calculation parameters related to the infusion state.
According to a preferred embodiment, when the infusion parameters are about to exceed and/or fall below the standard range, the alarm module can send out an early warning signal to remind a patient or medical staff to adjust the infusion parameters in time so as to ensure the life safety of the patient. Further, processing module 200 can be with the parameter value that alarm information corresponds with upload to disease supervisory systems to become the information in the aforementioned personal file, so that medical personnel can know the influence degree of different infusion states to the disease based on alarm information when looking over disease infusion state, thereby make the counter-measure in advance.
