Abstract
Description
Technical Field
[0001] Embodiments of the present disclosure relate to the field of hot perfusion temperature control systems, and in particular to a hot perfusion pipeline flow monitoring method, device, and computer equipment. Background Art
[0002] As we all know, extensive chest and abdominal implant metastasis after malignant tumor surgery is the main cause of patient deterioration and death. The treatment method of hot perfusion chemotherapy is to inject hot water of about 43 degrees into the body through a tube, and then discharge it from the body through another tube after treatment.
[0003] The flow rate of the perfusion pipeline equipped for different patients is different, so it is necessary to change the power of the peristaltic pump according to different groups of people to adjust the flow value of the circulating liquid in the perfusion pipeline. In addition, when the circulating liquid circulates in the perfusion pipeline, due to other situations (such as incomplete blockage of the pipe), the water pressure at the water outlet and the water inlet of the water bag will change, which means that the flow rate in the perfusion pipeline has changed. The change in the flow rate of the circulating liquid in the perfusion pipeline may affect the thermal perfusion effect at the least, and may damage the internal tissue of the human body cavity and cause iatrogenic injury at the worst. In addition, we know that when the power of the heat exchange rod is constant, the greater the flow rate (i.e., flow velocity) of the circulating liquid in the perfusion pipeline per unit time, the lower the temperature change rate of the perfusion liquid. Therefore, the flow rate of the circulating liquid must also be related to the change in temperature to ensure that the temperature and flow are compatible.
[0004] The existing hot perfusion chemotherapy devices have a reasonable accuracy in monitoring the flow rate in the perfusion pipeline, but are unable to adjust the flow information based on the temperature conditions at multiple locations in the pipeline, and are unable to automatically find the most suitable flow information at the moment, resulting in an inability to automatically adjust the flow rate in the perfusion pipeline. This requires medical staff to constantly monitor the temperature and flow data in the perfusion pipeline, which increases the workload of medical staff and affects the treatment effect of the current hot perfusion chemotherapy devices.

[0022] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0023] Figure 1 A process 100 according to some embodiments of a method for monitoring flow rate of a hot perfusion pipeline is shown. The method for monitoring flow rate of a hot perfusion pipeline comprises the following steps:
[0024] Step 101, obtaining temperature information of multiple positions of the perfusion pipeline;
[0025] In some embodiments, the plurality of positions are five in total, which are respectively distributed at the water bag outlet end, the water bag inlet end, the body inlet end, the body outlet end and the heating body of the heated water cup on the perfusion pipe. The temperature values of the circulating liquid at the above five positions are synchronously collected, and a vector value is formed according to the temperature values obtained at the five positions as the basic data for evaluating the temperature deviation value characteristics. The executor of this step can be a high-precision PT1000 thermistor temperature sensor with an accuracy of up to 0.05 degrees Celsius, which can accurately collect the temperature information of the above five positions.
[0026] Step 102, obtaining water pressure information of the circulating perfusion liquid at the inlet and outlet of the water bag;
[0027] In some embodiments, a pressure sensor is used to collect water pressure values at the water inlet and water outlet of the water bag; and the water pressure difference between the water inlet and water outlet of the water bag at the same time is obtained;
[0028] Step 103, comparing the temperature values of the circulating liquid at multiple positions with the preset temperature values for treatment to obtain a temperature deviation value characteristic;
[0029] In some embodiments, the cosine similarity between the vector formed by the temperature of the circulating liquid at five positions and the set temperature is obtained to construct the temperature deviation value feature of the current thermal perfusion chemotherapy temperature feature vector, and the cosine similarity between the vector formed by the temperature of the circulating liquid at five positions and the preset temperature vector of the circulating liquid at the five positions is negatively correlated;
[0030] In the embodiment of the present disclosure, similarity calculation is performed between the temperature vectors of the above five positions and the preset temperature vector, and the temperature deviation feature is obtained using cosine similarity, and the formula is as follows:
[0031]
[0032] Wherein, a and b are adjustment parameters used for normalizing the temperature deviation value calculation formula. The specific values can be set according to the actual situation. In this embodiment, a=1 and b=2 are set;
[0033] Using cosine similarity, the temperature deviation value X between the temperature vector Ti at multiple different positions in the current perfusion pipeline and the preset temperature vector T0 in the space vector is obtained. The temperature deviation value X represents the adaptability of the current hot perfusion temperature. The larger the difference value, the greater the difference between the current hot perfusion parameter and the ideal chemotherapy temperature in the patient's treatment temperature. Conversely, it means that the current hot perfusion fluid temperature in the patient's body is tending to the ideal value.
[0034] In some optional implementations of the embodiments of the present disclosure, the acquisition frequency of the above temperature information can be set to 15 Hz, and the temperature data of each current position for 5 seconds is obtained. In this way, the average value of the temperature data within five seconds of each position is used as the temperature information per unit time of the position, and the temperature values of the five positions collected and the measured position information are used as the high-dimensional feature vector T of the temperature. i ={t1,…,t5}, the preset temperature vector T0 ={T1,…,T5} of the five positions is used as a reference value. The specific preset temperature is the optimal temperature of the historical clinical treatment data. The preset temperature can also be set by the attending physician according to the patient's condition. Under this formula, according to T i Changes, and finally the specific temperature deviation X can be obtained.
[0035] Step 104, obtaining a water pressure balance value characteristic according to the difference in water pressure of the circulating liquid at the inlet and outlet of the water bag.
[0036] In some embodiments, according to the formula Calculate water pressure balance value characteristics;
[0037] Among them, the water pressure sensor data F at the inlet and outlet of the water bag i ,f j , where i and j are the subscript indices of the pressure sensor data at the inlet and outlet of the water bag respectively;
[0038] The acquisition frequency of the water pressure sensor is 15 Hz, and the unit time length for obtaining the infusion liquid under the current infusion pipeline flow is 5 seconds, which is the same as the frequency and period of temperature information acquisition in step 103. The absolute value of the difference between the water pressure data at the inlet and outlet of the water bag within five seconds is accumulated as the water pressure difference at the inlet and outlet ends, so as to obtain the water pressure balance value S of the infusion liquid at the inlet and outlet ends of the water bag within the unit time.
[0039] Step 105, generating a joint evaluation of the matching degree of the perfusion pipeline flow value under the current patient perfusion condition according to the temperature deviation value feature and the water pressure balance value feature;
[0040] In some embodiments, the data obtained in step 103 and step 104 are processed according to the formula Calculate the matching degree of the perfusion pipeline flow value under the joint evaluation to the current patient perfusion status;
[0041] Among them, Pi represents the matching degree, It is the ratio of the water pressure balance evaluation at the inlet and outlet of the water bag under the current perfusion pipeline flow rate to the temperature characteristic deviation value;
[0042] The larger the matching degree Pi value is, the smaller the temperature deviation of the circulating medicine in the current perfusion pipeline is and the better the water pressure balance at the water inlet and outlet of the water bag (i.e., the inlet and outlet of the pipeline), thereby enhancing the effect of the patient's thermal perfusion therapy. On the contrary, it means that the current flow rate is less matched with the patient's body benefits, which is not conducive to the treatment of the patient.
[0043] Step 106, based on the whale optimization algorithm, searching for the result that best matches the patient's thermal perfusion condition, and generating the optimal flow value in the thermal perfusion pipeline;
[0044] In some embodiments, first, it is necessary to define an adjustable flow value range as L, and the attending physician confirms the specific flow range L according to the actual clinical situation. According to clinical experience, the adjustable flow value range L is generally set to [400, 600], in units of ml / min, and the amount of each incremental increase / decrease is 2 ml / min. The matching degree between the adjusted flow value L and the patient is calculated again;
[0045] According to the calculation formula: L j+1 =L rand -A1*D k , perform optimal search within the flow range L;
[0046] Among them, each increased flow value is used as the one-dimensional position L of the whale optimization algorithm j , which is represented as a flow value within the flow range L. The whale optimization algorithm is used to find the next position L of each one-dimensional position within the flow value range L. j+1 , L rand represents the flow iteration value, that is, the optimal flow value before the current iteration number. C1 = 2r2. According to the operation rules of the whale optimization algorithm, a is a constant that linearly decreases from 2 to 0 as the iteration number increases, and r1, r2 are random numbers between 0 and 1;
[0047] Based on this, a fitness function calculation model in the optimization process of the whale optimization algorithm is constructed, and a flow iteration value L is obtained after each operation. rand , each flow iteration value L rand corresponding best pressure balance degree s i and best temperature deviation value x i are fixed values, that is are determined values. At this time, is substituted into the evaluation formula of the matching degree P, and it can be used to evaluate each flow value L within the flow range L. j matching degree In, S i the larger the value, the higher the adjustment accuracy of the water pressure balance degree, and X i the smaller the value, the closer the temperature characteristics of the circulating liquid at the five positions are to the preset temperature;
[0048] In some alternative implementation manners of the present disclosure embodiment, according to the patient's own situation, the attending physician sets the water pressure balance degree S0 to 0.9 and the temperature characteristic deviation value X0 to 0.26. Then, the search termination condition of the whale optimization algorithm is determined as: the water pressure balance degree S i > S0, the temperature characteristic deviation value X i < X0; and making the matching degree of the flow iteration value L rand matching degree
[0049] In this way, the current flow iteration value L rand is determined to be the most suitable flow value in the current perfusion pipeline.
[0050] Similarly, if it is directly detected that the matching degree evaluation of the perfusion pipeline flow meets the search termination condition, that is, there is no need to perform the operations in this method;
[0051] In summary, the above-mentioned step 105 and step 106 and their related contents, as an inventive point of an embodiment of the present disclosure, solve the problem mentioned in the background technology that the flow information cannot be adjusted based on the temperature conditions at multiple positions in the pipeline, and the most suitable flow information cannot be found at the moment; according to the flow range L confirmed in advance by the attending physician, when the temperature changes or incomplete pipe blockage occurs, the temperature deviation value characteristics and the water pressure balance value characteristics change. At this time, through the above-mentioned whale optimization algorithm, the most matching flow value can be found within the flow range L after fewer comparisons, thereby ensuring that the temperature of the circulating liquid tends to be constant and the water pressure tends to be balanced.
[0052] Step 107: convert the optimal flow value into an electrical signal and send it to the terminal device, so that the terminal device adjusts the flow of the perfusion pipeline.
[0053] In some embodiments, the main controller converts the best matching flow value in the current perfusion pipeline into an electrical signal for adjusting the peristaltic pump power, thereby changing the peristaltic pump power and adjusting the flow in the perfusion pipeline in time to ensure that the water pressure tends to balance.
[0054] In summary, through this method, firstly, the attending physician can preliminarily select the perfusion pipeline flow range L based on the patient's own situation, and obtain the temperature deviation value characteristics by comparing the temperature data monitored at the inlet, outlet and heating body in the heating cup; according to the difference in water pressure of the circulating medicine at the inlet and outlet of the water bag, the water pressure balance value characteristics are obtained; then, the temperature deviation value characteristics and the water pressure balance value characteristics are comprehensively evaluated to obtain the matching degree of the patient at the perfusion pipeline flow at the current temperature, and the changes in the temperature and water pressure of the circulating liquid in the perfusion pipeline can be monitored in time. Finally, through the whale optimization algorithm, the perfusion flow value that best matches the current perfusion condition can be quickly obtained within the adjustable flow range L, thereby ensuring that the temperature tends to a constant value and the water pressure remains balanced again.
