Intelligent pressure regulating hemostasis device for transradial intervention puncture port

Abstract

The present application relates to the technical field of medical apparatus and instruments, and discloses an intelligent pressure regulating and hemostasis device for radial artery intervention puncture, which comprises an MCU processor, a sensor signal acquisition module, an air pump, a first air pressure sensor, a second air pressure sensor, a first air bag, a second air bag, a first pressing plate assembly, a second pressing plate assembly, a jet device, a blood leakage sensor and an intelligent wearable blood pressure sensor. The MCU processor coupled with a clustering algorithm and a support vector machine algorithm continuously intelligently optimizes the dynamic relative pressure values of the two air pressure sensors, so that the optimal hemostasis effect of the patient's puncture port is achieved. During each pressure release process, part of the gas in the two air bags is discharged through the jet device via the total exhaust pipeline. The negative pressure generated by the siphon inlet of the jet device causes the blood leaking from the patient's puncture port to be absorbed into the defatted cotton in the negative pressure chamber, effectively preventing the blood leaking from the patient's puncture port from overflowing and polluting the environment. The two pressing plate assemblies can be reused after disinfection, which reduces the cost of the patient's surgical treatment compared with the mechanical pressure device.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an intelligent pressure regulating and hemostasis device for radial artery intervention puncture. BACKGROUND

[0002] After radial artery intervention, conventional hemostasis requires local compression of the patient's puncture for several hours. Currently, mechanical pressure devices are commonly used in clinical practice, such as patent number "CN212438729U" and name "radial artery puncture limiting compression hemostat". The hemostat needs to be manually screwed during use, and the initial pressure cannot be accurately controlled. If the initial pressure is too small, the patient's puncture will bleed, and if the initial pressure is too large, the patient's arm will be painful and significantly uncomfortable. The doctor needs to release the pressure gradually during the hemostasis process, which not only wastes the doctor's energy, but also has the possibility of displacement of the pressure device each time the pressure is released, causing the blood oozing from the patient's puncture to spill and contaminate the environment. Artificial monitoring of the patient's puncture for bleeding has the risk of not being able to detect bleeding from the patient's puncture in time. Mechanical pressure devices are disposable, which not only wastes resources, but also increases the cost of the patient's surgical treatment. SUMMARY

[0003] Since the radial artery and the ulnar artery are connected by the deep palmar branch and the superficial palmar branch, occlusion of the ulnar artery for a short time or the flow of a small amount of blood in the ulnar artery to the palm center reduces the blood pressure on the palm side of the patient's radial artery puncture, which is beneficial to the flow of a small amount of blood from the radial artery to the palm through the puncture, and avoids long-term compression and blockage of the radial artery blood flow to the palm during hemostasis, thereby preventing complications such as radial artery thrombosis and radial artery occlusion. For this reason, the present application provides an intelligent pressure regulating and hemostasis device for radial artery intervention puncture to solve the problem that the radial artery compression hemostasis device in the prior art cannot scientifically and effectively compress the ulnar artery and the blood oozing from the puncture during the hemostasis process of the patient's radial artery puncture, which pollutes the environment.

when the average value of the first air pressure sensor and the second air pressure sensor dynamic relative pressure value decreases to the minimum pressure value P min , due to the influence of individual difference factors such as the thickness of subcutaneous fat and the elasticity of blood vessels of the patient's arm, the patient's puncture port may appear the following two situations: ① generally no bleeding (the number of exuded red blood cells is less than 10 2 / s), the intelligent wearable blood pressure sensor detects that the systolic pressure of the patient is 0 mmHg, that is, the radial artery S1 and the ulnar artery S2 are both blocked from flowing blood to the palm center; 2) In special cases, the bleeding sensor detects that the patient's puncture port has no bleeding, and the intelligent wearable blood pressure sensor detects that the systolic pressure of the patient is 5-15 mmHg, that is, the radial artery S1 has blood flowing to the palm center, and the ulnar artery S2 has no blood flowing to the palm center; for the above two cases, the MCU processor makes the third electromagnetic valve in the middle connected, the second air bag stops deflating, and the first air bag continues to deflate until the bleeding sensor detects that the puncture port has a small amount of bleeding (the number of red blood cells exuded is less than 10 5 / s), the intelligent wearable blood pressure sensor detects that the systolic pressure of the patient is 0 mmHg, that is, the radial artery S1 and the ulnar artery S2 are both blocked from flowing blood to the palm center;

[0077] When the pressure maintaining time of the first air bag and the second air bag reaches the set pressure maintaining time T, the MCU processor makes the second electromagnetic valve right and the third electromagnetic valve right connected respectively, and the first air bag and the second air bag start to deflate respectively until the bleeding sensor detects that the patient's puncture port has a small amount of bleeding, the MCU processor makes the air pump start to work, the MCU processor makes the second electromagnetic valve left and the third electromagnetic valve in the middle connected respectively, the second air bag stops deflating, and the first air bag starts to inflate until the bleeding sensor detects that the patient's puncture port has no bleeding, and the intelligent wearable blood pressure sensor detects that the systolic pressure of the patient is 35-45 mmHg, the MCU processor makes the second electromagnetic valve in the middle and the third electromagnetic valve right connected respectively, the first air bag stops deflating, and the second air bag starts to deflate until the intelligent wearable blood pressure sensor detects that the systolic pressure of the patient is 25-35 mmHg, the MCU processor makes the third electromagnetic valve in the middle connected, the MCU processor makes the air pump stop working, and the first air bag and the second air bag start to maintain pressure for the second time; the optimal relative pressure values of the first air bag and the second air bag for the second time are P 12 and P 22, the blood flow of radial artery S1 and ulnar artery S2 to the palm center is respectively increased than the blood flow of each to the palm center in the first time of maintaining pressure.

[0078] The dynamic relative pressure value signal of the first air pressure sensor, the bleeding sensor signal, the dynamic relative pressure value signal of the second air pressure sensor and the intelligent wearable blood pressure sensor signal are fused, and the MCU processor is coupled with the clustering algorithm K-mean and the support vector machine algorithm SVM to intelligently optimize and determine the optimal relative pressure value P 1i of the first air bag in the i-th time of maintaining pressure 2i , and the optimal relative pressure value P 1i of the second air bag in the i-th time of maintaining pressure 2i , until the dynamic relative pressure values of the first air pressure sensor and the second air pressure sensor are respectively reduced to zero after several exhaust pressure releases of the first air bag and the second air bag, the MCU processor makes the buzzer emit an alarm prompt sound, and the optimal hemostasis effect of the patient's puncture port is realized.

[0080] In the above working process of the application, the MCU processor is coupled with the clustering algorithm K-mean and the support vector machine (SVM) algorithm, and the main process of the coupling of the two algorithms is briefly described as follows:

[0081] 1. We assume that the dynamic relative pressure values of the first air pressure sensor and the second air pressure sensor are P 1i and P 2i respectively.

[0082] 2. According to the systolic pressure (SYS) value, the platelet (PLT) value, the activated clotting time (ACT) value and the partial activated thromboplastin time (APTT) value as the basic indexes, the data are classified, different patient samples have corresponding systolic pressure (SYS) value, platelet (PLT), activated clotting time (ACT) value and partial activated thromboplastin time (APTT) value, and after a large number of sample statistics, they are summarized in a pre-training table, and based on SVM, a plurality of groups of data are trained, each group of data is {(P 1i , P 2i , T i ), yi}, wherein (P 1i , P 2i , T i ) represents the row vector of P1, P2, and T of the i-th sample point, y (i) represents the class label of the i-th sample point, taking values of 0 / 1 / 2…, which can be determined from the bleeding sensor and smart wearable blood pressure sensor signal acquisition, further, through the clustering algorithm K-mean method, first, various data are clustered, various data of different patient groups are classified, when different parameter systolic blood pressure (SYS) value, platelet (PLT) value, activated clotting time (ACT) value and partial activated clotting time (APTT) value of the patient group appear in the sample category, the similarity characteristics between the indicators are clustered through K-mean clustering, and then different class labels 4 / 5 / 6… are added.

[0083] Finally, the most suitable model and the related parameters of the hemostatic patient are selected by adjusting the parameters of the model in the SVM for classification, and the steps of SVM and intelligent control adjustment are as follows:

[0084] Step 1. The dynamic relative pressure values of the first air pressure sensor and the second air pressure sensor are initialized as P min .

[0085] Step 2. Collecting patient data during the puncture port hemostasis process, including the dynamic relative pressure values of the first air pressure sensor and the second air pressure sensor, the bleeding sensor and the smart wearable blood pressure sensor dynamic signal;

[0086] 3. Perform SVM training and logical intelligent judgment:

[0087] The smart wearable blood pressure sensor detects the pulse intensity of the patient's radial artery and the systolic pressure value increases with the increase of the blood flow through the patient's puncture port, and under the condition that the bleeding sensor detects that the patient's puncture port has no bleeding at the beginning of each pressure maintenance, the second air bag compresses the ulnar artery S2 to reduce the blood flow to the radial artery S1 puncture port, and the blood flow to the palm, and with the increase of the pressure maintenance times, the blood flow of the radial artery S1 and the ulnar artery S2 increases respectively, and the smart wearable blood pressure sensor detects the pulse intensity and systolic pressure value of the patient, which increases respectively.

[0088] If the relative pressure value of the second air bag is increased, it is beneficial to realize that the radial artery S1 has a larger blood flow to the palm, but the blood flow of the ulnar artery S2 to the palm is reduced; under the condition that the bleeding sensor detects that the patient's puncture port has no bleeding at the beginning of each pressure maintenance, and the total amount of blood flow to the palm of the radial artery S1 and the ulnar artery S2 is maximized, the minimum relative pressure value of the first air bag is its optimal value P 1i , and the minimum relative pressure value of the second air bag is its optimal value P2i Let y (i) = 0, indicating good hemostatic effect;

[0089] When one of the dynamic relative pressure values of the first and second air pressure sensors is less than its optimal value or both are less than their optimal values, the bleeding sensor detects that the patient's puncture site has bleeding (the number of exuded red blood cells is greater than 10 7 / s) or the intelligent wearable blood pressure sensor detects that the patient's systolic pressure is 0 mmHg, let y (i) = 1, indicating poor hemostatic effect;

[0090] When one of the dynamic relative pressure values of the first and second air pressure sensors is greater than its optimal value or both are greater than their optimal values, the bleeding sensor detects that the patient's puncture site has no bleeding or the intelligent wearable blood pressure sensor detects that the patient's systolic pressure is 0 mmHg (or the systolic pressure value is less than the previous pressure maintenance systolic pressure value), let y (i) = 2, indicating poor hemostatic effect;

[0091] The kernel function is extended to a hyperplane in high-dimensional space:

[0092] w T x+b=0

[0093] w represents the normal vector and b represents the displacement term.

[0094] The values of w and b are calculated using the Lagrange multiplier method and the KKT condition.

[0095] The support vectors satisfy:

[0096] y (i) (w* T x (i) +b*)=1,i=1,2,...,N

[0097] Decision function:

[0098] f(x)=sign(w T x+b*)

[0099] sign represents the sign function.

[0100] The core of SVM training is to solve a quadratic programming problem, that is, to minimize:

[0101]

[0102] where C is the penalty parameter and ξ (i) is the relaxation variable.

[0103] The target is to intelligently optimize the pressure maintaining relative pressure value of the first air bag and the pressure maintaining relative pressure value of the second air bag. In the optimization process, the SVM algorithm calculates the minimum discriminant boundary to feed back the dynamic relative pressure values of the first air pressure sensor and the second air pressure sensor in real time to optimize the puncture port hemostasis effect of the patient, and the feedback information is used to continuously optimize the dynamic relative pressure value of the first air bag and the pressure maintaining relative pressure value of the second air bag.

[0104] The process of data classification by SVM is as follows:

[0105] Step 1. Initialize the pressure maintaining relative pressure value of the first air bag and the pressure maintaining relative pressure value of the second air bag.

[0106] Step 2. Collect real-time data during the hemostasis process, including the pressure maintaining relative pressure values of the first air bag and the second air bag, the corresponding bleeding conditions and the systolic pressure;

[0107] Step 3. Train the collected data by SVM to learn the optimal parameters, i.e. find an interval hyperplane that can maximize the hemostasis effect of the two classes.

[0108] The "interval hyperplane" refers to the distance from the nearest data point on each side of the hyperplane to the hyperplane. In the support vector machine (SVM) classification algorithm, we want to find a "maximum interval hyperplane", that is, a hyperplane that maximizes the distance (interval), because such a hyperplane can effectively minimize classification errors and overfitting problems. In general, the interval hyperplane can be regarded as a specific hyperplane, which is defined in the context of classification problems.

[0109] Step 4. In the training process, cross-validation is used to evaluate the model and select the optimal hyperparameters.

[0110] Step 5. Further select the most suitable model by adjusting the parameters of the model in SVM, such as the maximum number of iterations of the linear SVC model and the penalty coefficient C. Use the squared error to measure the test target and the predicted value, find the smallest squared error model as the current SVM model, and select the final segmentation hyperplane logic intelligent judgment under the model;

[0111] Step 6. Use the obtained optimal hyperplane to make predictions, i.e. calculate the optimal value of the dynamic relative pressure values of the first air pressure sensor and the second air pressure sensor. When the host obtains new patient data, according to the systolic pressure (SYS), platelets (PLT), activated clotting time (ACT) and partial activated clotting time (APTT) of the data, the new data can be represented in the prediction domain, and then the hyperplane of the existing SVM model is used for division. The hyperplanes mean different classes;

[0112] Step 7, update the dynamic relative pressure value of the first air pressure sensor and the dynamic relative pressure value of the second air pressure sensor, the optimal relative pressure value of the first air pressure sensor and the second air pressure sensor is P 1i and P 2i ,

[0113] 7.1 According to the current relative pressure value of the first air pressure sensor and the current relative pressure value of the second air pressure sensor, respectively input into the SVM algorithm for prediction, if the current state prediction result is 1, indicating that the relative pressure value is too small, then increase the pressure value by 5 Pa per second, until the optimal relative pressure value P 1i and the optimal relative pressure value P 2i of the second air pressure sensor are reached respectively;

[0114] 7.2 According to the current relative pressure value of the first air pressure sensor and the current relative pressure value of the second air pressure sensor, respectively input into the SVM algorithm for prediction, if the current state prediction result is 2, indicating that the relative pressure value is too large, then decrease the pressure value by 5 Pa per second, until the optimal relative pressure value P 1i and the optimal relative pressure value P 2i of the second air pressure sensor are reached respectively;

[0115] 7.3 According to the current relative pressure value of the first air pressure sensor and the current relative pressure value of the second air pressure sensor, respectively input into the SVM algorithm for prediction, if the current state prediction result is 0, which is normal matching with the target relative pressure value, at this time, it shows that there is no blood exudation and there is a good systolic pressure value, then the relative pressure value of the first air bag and the relative pressure value of the second air bag do not need to be changed;

[0116] 7.4 According to the category labels 4 / 5 / 6… etc. outside the three states divided by the above clustering, adjust the indicators of each category in detail, such as the dynamic relative pressure value of the first air bag or the dynamic relative pressure value of the second air bag is too high, exhaust the first air bag or the second air bag to lower its relative pressure value appropriately; such as the dynamic relative pressure value of the first air bag or the dynamic relative pressure value of the second air bag is too low, inflate the first air bag or the second air bag to raise its relative pressure value appropriately; such as the dynamic relative pressure value of the first air bag or the dynamic relative pressure value of the second air bag is in an intermediate state, then execute it according to the most likely predicted classification.

[0117] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and not to limit, although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
