[0041] When t p <t a And t o <t a And t r <t a When t w The patient's status data is collected again after a certain period of time.

[0043] When P∈[P1,P2] and O∈[O1,O2] and R∈[R1,R2], then the enema instrument continues to work;

The accompanying drawings are for illustration purposes only and are not to be considered as limiting the present invention. The same reference symbols are used throughout the drawings to represent the same components. In the drawings:

[0059] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art. It should be noted that, unless there is a conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the implementation regulations.

[0060] Reference Figure 1 As shown, in some embodiments of the present application, a flow rate and temperature control method for an enema instrument includes:

[0061] S1, using sensors to obtain the real-time flow rate and temperature of the enema solution;

[0062] S2, obtaining basic data of the patient, including height, weight, age, and intestinal motility frequency;

[0063] S3, calculating a flow rate threshold and a temperature threshold of the enema liquid based on the basic data;

[0064] S4, comparing the real-time flow rate and the real-time temperature with the flow rate threshold and the temperature threshold, respectively, and synchronously adjusting the flow rate and temperature of the enema liquid based on the comparison results;

[0065] S5, obtaining the patient's status data, including blood pressure, blood oxygen, and heart rate;

[0066] S6, calculating the patient's blood pressure range threshold, blood oxygen range threshold, heart rate range threshold and other status data range thresholds based on the basic data and the adjusted flow rate and temperature data;

[0067] S7, comparing the state data with the state data range threshold, and adjusting the working state of the enema instrument based on the comparison result.

[0068] Specifically, the patient's intestinal peristalsis frequency can be obtained by placing a pressure sensor on the patient's abdominal surface or using ultrasonic Doppler technology. The pressure sensor can sense the pressure changes caused by intestinal peristalsis, and the ultrasonic Doppler can monitor the blood flow signals of intestinal smooth muscle movement. Both convert physical signals into electrical signals through the signal acquisition and analysis system. After filtering, amplification and other processing, the number of peristalsis per unit time is calculated to obtain the intestinal peristalsis frequency.

[0069] It is understandable that the enema fluid flow rate and temperature are obtained in real time through sensors, the threshold is calculated in combination with the patient's basic data, and the flow rate and temperature are adjusted synchronously. At the same time, the patient's blood pressure, blood oxygen, heart rate and other status data are monitored to dynamically adjust the instrument's working status, thereby achieving precise control of the enema fluid flow rate and temperature. It can be personalized according to the patient's individual situation, and can also monitor the patient's status in real time to ensure safety. The data is recorded throughout the process to generate a log, which improves the safety, comfort and controllability of the enema operation.

[0070] In some embodiments of the present application, synchronously adjusting the flow rate and temperature of the enema liquid based on the comparison result includes:

[0071] The real-time flow rate is preset to be V, the real-time temperature is preset to be T, the flow rate threshold is preset to be V0, and the temperature threshold is preset to be T0;

[0072] When V<V0 and T<T0, the output power of the power component is increased, and at the same time, the output power of the heating component is increased according to the first coordination coefficient;

[0073] When V < V0 and T > T0, the output power of the power component is increased, and the output power of the heating component is reduced according to the second coordination coefficient;

[0074] When V>V0 and T<T0, the output power of the power component is reduced, and the output power of the heating component is increased according to the third coordination coefficient;

[0075] When V>V0 and T>T0, the output power of the power component is reduced, and at the same time, the output power of the heating component is reduced according to the fourth coordination coefficient.

[0076] Specifically, the first to fourth synergy coefficients are the flow rate-temperature coupling influence factor matrices determined through heat exchange experimental data.

[0077] Specifically, the calculation formula for the flow rate threshold is: V0 = f1 (BMI, A, F), and the calculation formula for the temperature threshold is: T0 = f2 (BMI, A, F), where, W is weight, H is height, A is age, F is intestinal motility frequency, BMI is body mass index, and f1 and f2 are obtained through regression analysis or machine learning algorithms using a large amount of clinical data training.

[0078] It is understandable that the specific adjustment logic based on the comparison results of real-time flow rate, temperature and threshold value is clarified. The real-time flow rate, temperature and corresponding threshold values ​​are preset, and the power output of the power and heating components are adjusted synchronously in four situations (such as increasing the power of the power component and the heating component when the real-time flow rate is lower than the threshold and the temperature is lower than the threshold, etc.), so that the coordinated adjustment of flow rate and temperature is well-regulated, ensuring the accuracy and rationality of the adjustment to better match the patient's needs.

[0079] In some embodiments of the present application, adjusting the output power of the heating component according to the synergy coefficient includes:

[0080] The preset flow rate adjustment amount is ΔV, and the temperature compensation amount is ΔT;

[0081] ΔV=V0-V, based on the absolute value and direction of ΔV, the corresponding synergy coefficient K is retrieved from the preset synergy coefficient table;

[0082] ΔT=K×ΔV, and the output power of the heating component is adjusted based on ΔT.

[0083] Specifically, the preset synergy coefficient table is a flow rate-temperature compensation comparison table generated by combining fluid mechanics and heat conduction models with clinical data.

[0084] Specifically, the process of constructing the preset synergy coefficient table is as follows: a flow rate-temperature coupling mathematical model is established based on the Navier-Stokes equations and heat conduction equations in fluid mechanics, and the temperature change curves under different flow rate adjustment amounts are collected in combination with clinical data. The functional relationship between the flow rate adjustment amount and the temperature compensation amount is obtained by least squares fitting, and the functional relationship is discretized into a three-dimensional data table, where the X-axis is the absolute value of the flow rate adjustment amount, the Y-axis is the flow rate adjustment direction (increase or decrease), and the Z-axis is the corresponding synergy coefficient value. Finally, the data table is verified and calibrated through animal experiments to form the final preset synergy coefficient table.

[0085] Understandably, a specific method for adjusting the output power of the heating component based on the synergy coefficient is provided. A flow rate adjustment amount and a temperature compensation amount are preset. The synergy coefficient is retrieved from a preset synergy coefficient table based on the absolute value and direction of the flow rate adjustment amount. The heating component power is then adjusted based on this coefficient. This achieves a quantitative correlation between flow rate changes and temperature compensation, allowing temperature adjustments to more accurately match flow rate changes, improving the accuracy of the coordinated control of the two.

[0086] In some embodiments of the present application, when querying the corresponding synergy coefficient from a preset synergy coefficient table based on the absolute value and direction of ΔV, the following steps are included:

[0087] The preset flow rate adjustment threshold is ΔV th , the gradient adjustment amount is ΔV g , the stabilization time is t s ;

[0088] When |ΔV|>ΔV th When ΔV is decomposed into multiple gradient adjustments in the direction of making V approach V0, based on ΔV g The absolute value and direction of the corresponding sub-synergy coefficient K is retrieved from the preset sub-synergy coefficient table g , and perform synchronous adjustment of flow rate and temperature in sequence according to the gradient order, waiting for the stabilization time after each gradient adjustment before adjusting the next gradient;

[0089] When |ΔV|≤ΔV th When , the corresponding synergy coefficient K is queried from the preset synergy coefficient table based on the absolute value and direction of ΔV, and the flow rate and temperature are adjusted once.

[0090] Specifically, the flow rate adjustment threshold is the parameter mutation threshold determined by the system response characteristics, the sub-synergy coefficient table is a comparison table of gradient adjustment and sub-synergy coefficient determined by segmented experimental data, and the stabilization time is the parameter stabilization waiting time determined by the system thermal equilibrium time constant combined with clinical feedback data.

[0091] The sub-synergy coefficient table is constructed through segmented experiments. The flow rate adjustment amounts of different gradients are divided into multiple intervals. Multiple flow rate and temperature synergy adjustment experiments are carried out in each interval. The flow rate changes, temperature changes and corresponding compensation effects in each experiment are recorded. The synergy coefficient of temperature change with flow rate under different gradient adjustment amounts is calculated based on the experimental data. Finally, a corresponding relationship table between gradient adjustment amount and sub-synergy coefficient is compiled.

[0092] It's understandable that different adjustment strategies are used for different flow rate adjustments. When the flow rate adjustment exceeds a threshold, it is broken down into multiple gradient adjustments, adjusted sequentially and with a stabilization period after each gradient adjustment to ensure a smooth adjustment process. When the adjustment does not exceed the threshold, a single adjustment is made, balancing efficiency and stability to avoid discomfort to the patient due to excessive adjustments.

[0093] In some embodiments of the present application, when the flow rate and temperature are adjusted synchronously in a gradient order, the following steps are included:

[0094] The preset temperature change rate is The flow rate change rate is, the safety change rate is S, and the current gradient adjustment amount is ΔV g(n) , the next gradient adjustment is ΔV g(n+1) ;

[0095] when or When t s Maintain this state internally;

[0096] If t s back or Then adjust the subsequent gradient adjustment amount;

[0097] If t s back and Then continue with the synchronous adjustment of the flow rate and temperature of the next gradient;

[0098] when and , the flow rate and temperature of the current gradient will continue to be adjusted synchronously.

[0099] Specifically, the safe change rate is the critical value of safe change of physiological parameters determined by human intestinal tissue tolerance experiment

[0100] If t s back or The formula for adjusting the subsequent gradient adjustment amount is:

[0101] Where λ is the adjustment proportional factor determined by the system response characteristics.

[0102] It is understandable that parameters such as the temperature change rate, flow rate change rate and safety change rate are set. When adjusting according to the gradient, if the temperature or flow rate change rate exceeds the safety change rate, the adjustment is suspended and the state is maintained. Then, it is decided whether to adjust the subsequent gradient amount or continue to adjust according to the situation, which effectively prevents the flow rate or temperature from changing too quickly during the adjustment process and causing adverse effects on the patient, further ensuring the safety of the adjustment process.

[0103] In some embodiments of the present application, adjusting the working state of the enema instrument based on the comparison result includes:

[0104] The patient's blood pressure is preset to P, blood oxygen is O, heart rate is R, the blood pressure range threshold is [P1, P2], the blood oxygen range threshold is [O1, O2], and the heart rate range threshold is [R1, R2];

[0105] When P∈[P1,P2] and O∈[O1,O2] and R∈[R1,R2], then the enema instrument continues to work;

[0106] when or or When , the enema instrument stops working.

[0107] Specifically, [P1, P2] are the safe range thresholds of human blood pressure determined through clinical hemodynamic experiments, [O1, O2] are the safe range thresholds of blood oxygen determined through studies on the relationship between blood oxygen saturation and tissue oxygenation, and [R1, R2] are the safe range thresholds of heart rate determined through cardiac load tests.

[0108] Specifically, based on basic data (height, weight, age, intestinal peristalsis frequency) and adjusted flow rate and temperature data, by establishing a multivariate regression model or machine learning prediction model containing the above parameters, combined with the clinical physiological indicator safety range database, the blood pressure, blood oxygen, and heart rate range thresholds that match the patient's individual characteristics and current enema parameters are calculated, and the basic physiological threshold is determined using age and body mass index. The threshold range is then dynamically corrected according to the degree of intestinal stimulation caused by the adjusted flow rate and temperature.

[0109] Understandably, the rules for controlling the operating state of the enema instrument based on the comparison of patient status data with the threshold value of the status data range are clearly defined. The instrument continues to operate when the patient's blood pressure, blood oxygen, and heart rate are within the corresponding threshold ranges; otherwise, it stops. This allows the instrument to respond promptly to the patient's physiological state and avoid the safety risks of continuing the enema when the patient's condition is abnormal.

[0110] In some embodiments of the present application, when the enema instrument stops working, it includes:

[0111] The preset alarm threshold duration is t a , the duration of abnormal blood pressure is t p , the duration of abnormal blood oxygen is t o , the duration of abnormal heart rate is t r , the observation time is t w ;

[0112] When t p ≥t a or t o ≥t a or t r ≥t a When , the alarm signal is triggered;

[0113] When t p <t a And t o <t a And t r <t a When t w The patient's status data is collected again after a certain period of time.

[0114] Specifically, the alarm threshold duration is the allowed duration of abnormal physiological parameters determined by clinical safety standards.

[0115] Understandably, the system specifies an alarm and data recollection mechanism when the instrument stops working. When the duration of abnormal blood pressure, blood oxygen, or heart rate reaches the alarm threshold, an alarm signal is triggered. If the abnormality does not last longer than the corresponding standard and the observation time is up, the status data is recollected to promptly alert medical staff to the patient's abnormal condition. At the same time, by observing and recollecting data, it is determined whether the abnormality is temporary, thereby improving the safety and reliability of the instrument.

[0116] In some embodiments of the present application, at t w When the patient's status data is collected again after a certain period of time, it includes:

[0117] When P∈[P1,P2] and O∈[O1,O2] and R∈[R1,R2], then the enema instrument continues to work;

[0118] when or or , an alarm signal is triggered.

[0119] Understandably, the procedure for re-collecting patient status data is clarified. If all patient status data after re-collection are within the normal range, the instrument continues to operate. Otherwise, an alarm signal is triggered, ensuring that the enema operation can continue safely after the patient's condition returns to normal. At the same time, a timely alarm is triggered in the event of a persistent abnormal condition to ensure patient safety.

[0120] In some embodiments of the present application, during the operation of the enema instrument, the real-time flow rate, the real-time temperature, the adjusted flow rate and temperature data, the patient's basic data and the status data are recorded in real time, and an enema process data log is generated.

[0121] It is understandable that it is required to record the real-time flow rate, temperature, adjusted data, patient basic data and status data in real time during the operation of the enema instrument and generate a log to facilitate medical staff to trace the enema process afterwards, understand the changes in various parameters and patient status during the operation, provide a reference for subsequent operations, and also help analyze the enema effect and possible problems.
