Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent medical care, and particularly relates to a urinary catheter safety management system and monitoring method for comatose patients, as well as an electronic device and a computer program product for implementing the method. Background Art

[0002] Indwelling urinary catheterization is a commonly used invasive nursing operation in clinical practice. It is a method of retaining the urinary catheter in the bladder to drain urine, and is a basic means to solve abnormal urination and observe urine volume. The risk of infection increases due to the long indwelling time of the urinary catheter. In the daily care process of bedridden patients with urinary incontinence, the most common method is also to urinate through an indwelling urinary catheter. Clinically, there are many patients with indwelling urinary catheters who have underlying diseases, mainly patients with coronary heart disease, pulmonary diseases, hypertension, convalescence of cerebral infarction, etc. They have a long bedridden and repeated hospitalization time, and often need to indwell urinary catheters due to coma, urinary incontinence or urinary retention. Some patients are more likely to develop urinary tract infections related to indwelling urinary catheters due to low immunity, long bedridden time and long indwelling time.

[0003] Chinese Patent Application CN201610239937 once proposed an electric induction urine collector for comatose female bedridden patients, which can effectively inhibit the infection at the perineum and the adhesion between the substrate and the skin. However, among actual long-term bedridden patients, most of the patients are in a normal state rather than a coma state for most of the time. In the normal state, the hospital clinical terminal and its urinary catheter monitoring device can be normally inspected, and the patient can also normally interact with the nursing staff or relevant terminals and monitoring devices. However, once the patient shows signs of coma, the patient is very likely to lose the ability to interact, but the urinary function is still normal. At this time, since the medical staff cannot obtain the patient information in time, it will lead to situations such as too long indwelling time, untimely replacement of the urinary catheter, or even life-threatening complications caused by long-term coma. However, there are also situations in the clinical environment where the patient is in normal rest (dozing, sleeping) and cannot interact in time. Therefore, how to effectively identify comatose patients with indwelling urinary catheters and avoid urinary tract infections is a problem that needs to be solved in the actual clinical scenario. Summary of the Invention

[0004] In view of the above technical problems, the present invention proposes a urinary catheter safety management system and monitoring method for comatose patients, as well as an electronic device and a computer program product for implementing the method.

[0005] In the first aspect of the present invention, a urinary catheter safety monitoring method for comatose patients is proposed, and the method is applied to a clinical terminal;

[0006] The method includes:

[0007] Collect multiple physical sign parameters of a target patient, where the target patient is a patient with an indwelling urinary catheter, and the physical sign parameters include electroencephalogram signals, respiratory rate, pulse frequency, blood pressure, body temperature, and facial skin color;

[0008] Based on the physical sign parameters, detect whether the target patient has a coma symptom;

[0009] When the target patient has a coma symptom, obtain multiple monitoring parameters obtained by the monitoring device corresponding to the indwelling urinary catheter;

[0010] Combine the multiple monitoring parameters and physical sign parameters to determine the actual coma state value of the target patient;

[0011] Based on the actual coma state value, perform a coma warning or execute a monitoring device update operation; the monitoring device update operation includes: reminding the target patient to interact with the monitoring device.

[0012] Wherein, the actual coma state value represents the possibility that the patient is in a coma state. The greater the possibility that the patient is in a coma state, the higher the actual coma state value.

[0013] Based on the actual coma state value, performing a coma warning or executing a monitoring device update operation specifically includes:

[0014] When the actual coma state value is within a certain risk range, perform a coma warning operation, and the coma warning operation is used to remind medical staff that the current target patient is already in a coma state;

[0015] When the actual coma state value is within an uncertain risk range, execute a monitoring device update operation to remind the target patient to interact with the monitoring device; if the target patient does not interact with the monitoring device within a preset time period, adjust the actual coma state value to a certain risk range.

[0016] The monitoring device reports the multiple monitoring parameters according to a first preset period;

[0017] When the actual coma state value is within a certain safety range, increase the first preset period.

[0018] When the actual coma state value is within an uncertain risk range, decrease the first preset period.

[0019] The combining the multiple monitoring parameters and physical sign parameters to determine the actual coma state value of the target patient specifically includes:

[0020] Input the multiple monitoring parameters and physical sign parameters into a pre-trained coma state value evaluation model to obtain the actual coma state value of the target patient.

[0021] When the actual coma state value output by the coma state value evaluation model is within the uncertainty risk range, perform a monitoring device update operation to remind the target patient to interact with the monitoring device;

[0022] Determine whether to retrain the coma state value evaluation model according to whether the target patient performs an interaction operation within a preset time period.

[0023] In a second aspect of the present invention, a urinary catheter safety management system for comatose patients is proposed, which is used to manage at least one indwelling urinary catheter patient. The system includes a clinical terminal corresponding to the indwelling urinary catheter patient and an indwelling urinary catheter monitoring device;

[0024] The clinical terminal collects a plurality of physical sign parameters of the indwelling urinary catheter patient, and the physical sign parameters include respiratory rate, pulse frequency, blood pressure, body temperature, and facial skin color;

[0025] Based on the physical sign parameters, detect whether the indwelling urinary catheter patient has coma symptoms;

[0026] When the indwelling urinary catheter patient has coma symptoms, obtain a plurality of monitoring parameters obtained by the indwelling urinary catheter monitoring device;

[0027] Combine the plurality of monitoring parameters and physical sign parameters to determine the actual coma state value of the indwelling urinary catheter patient;

[0028] Based on the actual coma state value, perform coma warning or perform a monitoring device update operation; the monitoring device update operation includes: reminding the indwelling urinary catheter patient to interact with the monitoring device;

[0029] The actual coma state value includes a certainty risk range, a certainty normal range, and an uncertainty risk range.

[0030] When the actual coma state value is within the certainty risk range, the clinical terminal performs a coma warning operation, and the coma warning operation is used to remind medical staff that the current target patient is already in a coma state;

[0031] When the actual coma state value is within the uncertainty risk range, the clinical terminal performs a monitoring device update operation to remind the indwelling urinary catheter patient to interact with the monitoring device; if the indwelling urinary catheter patient does not interact with the monitoring device within a preset time period, the clinical terminal adjusts the actual coma state value to the certainty risk range.

[0032] The aforesaid method for safely monitoring the urinary catheters of comatose patients can also be automatically implemented through various forms of electronic devices, physical machines, virtual machines, cluster servers, etc., by means of computer program instructions; the computer program instructions can be stored in storage media of different forms and loaded into computer electronic devices for execution.

[0033] Therefore, in the third aspect of the present invention, there is also provided a computer-readable storage medium for storing computer instructions, which, when run on an electronic device, cause the electronic device to execute all or part of the steps of the aforesaid method for safely monitoring the urinary catheters of comatose patients.

[0034] In the fourth aspect of the present invention, there is also provided an electronic device, which includes a processor and a memory. The memory is used for storing instructions, and the processor is used for calling the instructions in the memory, so that the electronic device executes the aforesaid method for safely monitoring the urinary catheters of comatose patients.

[0035] In the fifth aspect of the present invention, there is also provided a computer program product, which includes a computer program. When the computer program is executed, all or part of the steps of the aforesaid method for safely monitoring the urinary catheters of comatose patients are implemented.

[0036] The present invention adopts a variety of intelligent monitoring means to achieve the safe management of the urinary catheters of comatose patients at multiple levels and in stages, and can effectively identify comatose patients to avoid urinary tract infections. The specific advantages and implementation principles of the technical solution will be further detailed in the specific embodiment part in combination with the accompanying drawings of the specification. Description of the Drawings

Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other accompanying drawings can be obtained based on these drawings without creative efforts.

[0042] Figure 5 It is a schematic diagram of a specific working process of the urinary catheter safety management system for comatose patients. Specific Embodiments

[0043] In the specific embodiments of the present application, if the embodiments of the relevant technical solutions involve user-related data, when the embodiments of the present application are applied to specific products or technologies, user permission or consent is required, and the collection, use, and processing of the relevant data need to comply with the relevant laws, regulations, and standards of the relevant countries and regions.

[0044] See Figure 1 , Figure 1 It is the main flowchart of the method for safely monitoring the urinary catheters of comatose patients applied to a clinical terminal in an embodiment of the present invention.

[0045] Figure 1 The method includes multiple steps. For ease of description, the step numbers are marked as follows ( Figure 1 The step numbers are omitted in

[0046] S1: Collect multiple physical sign parameters of the target patient. The target patient is a patient with an indwelling urinary catheter. The physical sign parameters include electroencephalogram signal, respiratory rate, pulse frequency, blood pressure, body temperature, and facial skin color;

[0047] S2: Based on the physical sign parameters, detect whether the target patient has coma symptoms;

[0048] S3: When the target patient has coma symptoms, obtain multiple monitoring parameters obtained by the monitoring device corresponding to the indwelling urinary catheter;

[0049] S4: Combine the multiple monitoring parameters and physical sign parameters to determine the actual coma state value of the target patient;

[0050] S5: Based on the actual coma state value, perform coma warning or execute the monitoring device update operation; the monitoring device update operation includes: reminding the target patient to interact with the monitoring device.

[0051] In each embodiment of the present application, the actual coma state value represents the possibility that the patient is in a coma state. The greater the possibility that the patient is in a coma state, the higher the actual coma state value.

[0052] As an example, the actual coma state value is characterized by a coma probability value, which can be represented quantitatively or qualitatively. An example of quantitative representation is, for example, represented by a percentage score, where 0 indicates that it is completely impossible to be in a coma state, and 100 indicates being completely in a coma state.

[0053] An example of qualitative representation can be: a very low coma probability, a relatively high coma probability, a very high coma probability.

[0054] It can be understood that the above quantitative representation (quantification) can be converted into qualitative representation. For example, the score range of the quantitative representation is divided into three intervals, corresponding to the three possibilities of the qualitative representation respectively.

[0055] Based on the invention purpose, application scenario and clinical practice of the present application, the situation where the target patient has a very low coma probability or a very high coma probability is much less than the situation where the coma probability is relatively high.

[0056] Clinically, the main focus is on the situation where the target patient has a relatively high coma probability, because compared with the other two situations, the state in this situation is relatively ambiguous and it is not easy to draw a definite conclusion.

[0057] Therefore, in the technical solution of the present invention, for the actual coma state value, it is divided into three types of ranges: a definite risk range, a risk-free range, and an uncertain risk range, corresponding to the definite ranges at both ends (a very low coma probability, a very high coma probability) and the ambiguous and uncertain range (a relatively high coma probability) respectively.

[0058] For a better description Figure 1 of the specific implementation methods of each step of the Figures 2 - 3 embodiment, next, in combination with

[0059] First, execute steps S1 - S2, that is, after obtaining multiple physical sign parameters of the target patient, it can be preliminarily judged whether the target patient has coma symptoms;

[0060] Both clinical practice and theoretical research show that before a patient is about to enter a coma symptom, there will be certain changes in the physical sign parameters of the body, including electroencephalogram signals, respiratory rate, pulse frequency, blood pressure, body temperature, and facial skin color, which will be different from the normal state. Based on the recognition of these differential physical sign parameters, it can be preliminarily recognized whether the patient has coma symptoms;

[0061] However, there are still certain difficulties in automatically judging and recognizing coma symptoms clinically. The most important of these is to distinguish normal sleep symptoms, normal rest state (dozing) from the actual impending coma state.

[0062] Therefore, the appearance of coma symptoms in a patient does not necessarily mean that the patient will enter the actual coma state, especially for patients with indwelling urinary catheters. Some patients with indwelling urinary catheters need to stay in bed for a long time, resulting in less physical activity. After a long period of bed rest, some physical sign parameters may show coma characteristics.

[0063] In this regard, the first improvement of the present invention is implemented in steps S3 - S4. For specific details, please refer to Figures 2 - 3 .

[0064] In Figure 2 , an input - output schematic diagram of the coma state value evaluation model used in the technical solution of the present invention is shown.

[0065] Refer to Figure 2 , in step S3, by combining the multiple monitoring parameters and physical sign parameters, the actual coma state value of the target patient is determined, which specifically includes:

[0066] Input the multiple monitoring parameters and physical sign parameters into a pre - trained coma state value evaluation model to obtain the actual coma state value of the target patient.

[0067] In Figure 2 's embodiment, the actual coma state value output by the pre - trained coma state value evaluation model is quantitatively represented in a percentage system, specifically represented as multiple intervals from 0 to 100.

[0068] Among them, when the output actual coma state value is in the range of [0, 20], it is determined that there is no coma risk (the coma risk is very low / there is no coma risk); when the output actual coma state value is in

[0069] [66, 100] range, it is determined that there is a coma risk (the coma risk is very high).

[0070] In Figure 2 , the two situations are classified into a deterministic normal range and a deterministic risk range;

[0071] For the pre - trained coma state value evaluation model, when the scores in the above two ranges are output, the confidence level of its output result is very high;

[0072] On the other hand, when the output actual coma state value is in the range of [21, 65], it means that the coma risk is not very certain, that is, there may or may not be a risk, in a rather uncertain ambiguous zone, Figure 2 which is described as an uncertainty risk range.

[0073] For the pre-trained coma state value evaluation model, when the score within the above-mentioned uncertainty risk range is output, the confidence level of its output result is relatively low, meaning that the credibility of its result is also low.

[0074] This situation also conforms to the result statistical law of the relevant pre-trained models in the prior art.

[0075] However, as previously mentioned, the situations where the target patient has a very low or very high probability of being in a coma are much less than the situation where the probability of being in a coma is relatively high. Clinically, the main focus is on the situation where the target patient has a relatively high probability of being in a coma, because compared with the other two situations, this situation has a relatively ambiguous state and it is not easy to draw a definite conclusion. For the pre-trained coma state value evaluation model, when the score within the above-mentioned uncertainty risk range is output, it also means that the state is relatively ambiguous and it is not easy to draw a definite conclusion. The present invention will make targeted improvements in this regard.

[0076] Specifically, in combination with Figure 3 , Figure 3 is a schematic diagram of the corresponding operations performed based on different situations of the actual coma state value in the technical solution of the present invention.

[0077] Among them, based on the actual coma state value, coma warning or monitoring device update operation is performed, specifically including:

[0078] When the actual coma state value is within the definite risk range, a coma warning operation is performed, and the coma warning operation is used to remind medical staff that the current target patient is already in a coma state;

[0079] When the actual coma state value is within the definite normal range, the normal monitoring process is continued.

[0080] That is to say, for the above two "definite ranges", the method can be automatically executed without manual intervention or interaction.

[0081] When the actual coma state value is within the uncertainty risk range, a monitoring device update operation is performed to remind the target patient to interact with the monitoring device; if the target patient does not interact with the monitoring device within the preset time period, the actual coma state value is adjusted to the definite risk range.

[0082] When the actual coma state value is within the uncertainty risk range, the embodiment of the present invention introduces a further confirmation measure, specifically performing a monitoring device update operation to remind the target patient to interact with the monitoring device;

[0083] For example, the monitoring measure issues a voice reminder asking the target patient to give a response;

[0084] For another example, the monitoring status gives a certain status feedback to the target patient. For example, after gently shaking the nursing bed, the target patient is required to give a certain action feedback or voice feedback to confirm whether the patient is in a coma, asleep, or dozing off.

[0085] If the patient interacts with the monitoring device within a preset time period, it means that the patient has not entered a coma state. At this time, the actual coma state value is adjusted to the definite normal range, and the monitoring process is continued normally according to the process when the actual coma state value is in the definite normal range.

[0086] However, if the target patient does not interact with the monitoring device within the preset time period, it means that the possibility of the patient entering a coma state is very high. Then, the actual coma state value is adjusted to the definite risk range, and the process when the actual coma state value is in the definite risk range is followed, that is, a coma warning operation is performed. The coma warning operation is used to remind medical staff that the current target patient is in a coma state.

[0087] In the above embodiment, the monitoring device is a monitoring device dedicated to the indwelling urinary catheter, which is used to monitor various parameters of the indwelling urinary catheter, including urine pressure information, urine flow information, time information, etc. The monitoring device may specifically include functional modules such as a central processor control module, a hydraulic transmitter, a flow transmitter, a solenoid valve, a power supply module, and an internal catheter to achieve intelligent urine monitoring. The implementation structure and principle can refer to related existing technologies (such as CN118370543A), which is not the focus of the present invention and will not be specifically elaborated again.

[0088] The improvement of the present invention in the monitoring status is that the monitoring device reports the multiple monitoring parameters according to a first preset period.

[0089] When the actual coma state value is within the definite safety range, the first preset period is increased.

[0090] When the actual coma state value is within the indefinite risk range, the first preset period is decreased.

[0091] Clinically, the intelligent urine monitoring device needs to regularly send the urine catheter monitoring parameters of the indwelling urinary catheter patient to the backend management platform through the clinical terminal to remind medical staff to detect risks in time. However, the data sending period is usually set according to experience or default by the system and remains unchanged. This static data sending and monitoring method is not suitable for the situation where the status of clinical bedridden patients with indwelling urinary catheters is changeable.

[0092] Therefore, the present embodiment makes the above further improvements, that is, when the actual coma state value is within the deterministic safety range, the first preset period is increased. At this time, the patient is in a normal state, and the first preset period can be appropriately increased. Even in the case of special circumstances, since the patient is in a normal state and has normal interaction capabilities, there will be no medical risks.

[0093] On the other hand, when the actual coma state value is within the uncertain risk range, the first preset period is decreased, and the current situation of the patient needs to be monitored more frequently to avoid delay in analysis.

[0094] As described above, determining the actual coma state value of the target patient by combining the multiple monitoring parameters and physical sign parameters specifically includes:

[0095] Inputting the multiple monitoring parameters and physical sign parameters into a pre-trained coma state value evaluation model to obtain the actual coma state value of the target patient.

[0096] In practical applications, the training samples of the coma state value evaluation model can be pairs of intelligent urine monitoring parameters (including urine pressure information, urine flow information, time information, etc.), physical sign parameters (including electroencephalogram signals, respiratory rate, pulse frequency, blood pressure, body temperature, and facial skin color, etc.), and the corresponding patient annotation status (scores corresponding to coma / normal). The coma state value evaluation model is trained based on a known standard model in the prior art. The standard model can be a neural network model based on deep learning, or a bilinear / nonlinear fitting model fitted based on data pairs. The training method can be a feedback neural network, data fitting normalization, etc. The present invention does not make specific limitations on this.

[0097] The improvement of the present invention lies in under what circumstances the initially pre-trained coma state value evaluation model needs to be retrained.

[0098] Specifically, when the actual coma state value output by the coma state value evaluation model is within the uncertain risk range, a monitoring device update operation is performed to remind the target patient to interact with the monitoring device.

[0099] According to whether the target patient performs an interaction operation within a preset time period, it is determined whether to retrain the coma state value evaluation model.

[0100] Obviously, if the target patient performs an interaction operation within the preset time period, it means that the output result is not very accurate. At this time, the coma state value evaluation model needs to be retrained. The specific way of retraining can be to correct the result output this time and use it together with the data input this time as a supplementary training sample pair, which is added to the existing sample pairs to retrain the model.

[0101] Figures 1 - 3 The method embodiments have progressively introduced multiple advantages of the technical solution of the present invention and key improved technical means.

[0102] On this basis, Figure 4 The following system embodiments for implementing the method embodiments are further given:

[0103] A urinary catheter safety management system for comatose patients is used to manage at least one patient with an indwelling urinary catheter.

[0104] Specifically, Figure 4 It is shown that the system includes a clinical terminal corresponding to the patient with an indwelling urinary catheter and an indwelling urinary catheter monitoring device;

[0105] The clinical terminal collects multiple physical sign parameters of the patient with an indwelling urinary catheter, and the physical sign parameters include respiratory rate, pulse frequency, blood pressure, body temperature, and facial skin color;

[0106] Based on the physical sign parameters, it is detected whether the patient with an indwelling urinary catheter has a coma symptom;

[0107] When the patient with an indwelling urinary catheter has a coma symptom, multiple monitoring parameters obtained by the indwelling urinary catheter monitoring device are acquired;

[0108] Combining the multiple monitoring parameters and the physical sign parameters, the actual coma state value of the patient with an indwelling urinary catheter is determined;

[0109] Based on the actual coma state value, a coma warning is given or a monitoring device update operation is performed; the monitoring device update operation includes: reminding the patient with an indwelling urinary catheter to interact with the monitoring device;

[0110] The actual coma state value includes a definite risk range, a definite normal range, and an indefinite risk range.

[0111] When the actual coma state value is within the definite risk range, the clinical terminal performs a coma warning operation, and the coma warning operation is used to remind medical staff that the current target patient is in a coma state;

[0112] When the actual coma state value is within the indefinite risk range, the clinical terminal performs a monitoring device update operation, reminding the patient with an indwelling urinary catheter to interact with the monitoring device; if the patient with an indwelling urinary catheter does not interact with the monitoring device within a preset time period, the clinical terminal adjusts the actual coma state value to the definite risk range.

[0113] The system is further configured with a coma state value evaluation model and a model training unit;

[0114] Combining the multiple monitoring parameters and the physical sign parameters to determine the actual coma state value of the target patient specifically includes:

[0115] Inputting the multiple monitoring parameters and the physical sign parameters into a pre-trained coma state value evaluation model to obtain the actual coma state value of the target patient.

[0116] When the actual coma state value output by the coma state value evaluation model is within the uncertainty risk range, perform a monitoring device update operation to remind the target patient to interact with the monitoring device;

[0117] According to whether the target patient performs an interaction operation within a preset time period, the model training unit determines whether to re-train the coma state value evaluation model.

[0118] Obviously, if the target patient performs an interaction operation within the preset time period, it means that the output result is not very accurate. At this time, the model training unit needs to re-train the coma state value evaluation model. The specific way of re-training can be to correct the result output this time and use the corrected result and the input data this time as a supplementary training sample pair, add it to the existing sample pairs, and re-train the model.

[0119] Figure 5 Then a specific working process schematic diagram of the urinary catheter safety management system for comatose patients is given, specifically including ( Figure 5 Step numbers are omitted):

[0120] Step 1: The clinical terminal collects multiple physical sign parameters of the patient with an indwelling urinary catheter;

[0121] Step 2: Determine whether the patient with the indwelling urinary catheter has coma symptoms. If so, go to the next step; otherwise, return to the previous step;

[0122] Step 3: The clinical terminal obtains multiple monitoring parameters obtained by the indwelling urinary catheter monitoring device;

[0123] Step 4: Input the multiple monitoring parameters and the physical sign parameters into a pre-trained coma state value evaluation model to obtain the actual coma state value of the target patient;

[0124] Step 5: When the actual coma state value is within the uncertainty risk range, remind the patient with the indwelling urinary catheter to interact with the monitoring device and enter Step 6;

[0125] Otherwise, when the actual coma state value is within the deterministic risk range, coma warning is executed; when the actual coma state value is not within the deterministic risk range, which means the actual coma state value is within the deterministic normal range, the normal monitoring process is executed at this time, that is, return to Step 1;

[0126] Step 6: Determine whether the indwelling urinary catheter patient has interacted with the monitoring device within a preset time period. If so, adjust the actual coma state value to the deterministic normal range, and execute the normal monitoring process at this time, that is, return to Step 1;

[0127] If not, adjust the actual coma state value to the deterministic risk range and execute coma warning;

[0128] During actual execution, if the indwelling urinary catheter patient has not interacted with the monitoring device within a preset time period, after adjusting the actual coma state value to the deterministic risk range, it is sufficient to return to Step 4.

[0129] For other technologies, principles, algorithms or models not elaborated in detail in this application, reference can be made to the prior art.

[0130] As can be seen from the above various embodiments, the present invention adopts a variety of intelligent monitoring means to achieve the safety management of the urinary catheters of coma patients in multiple levels and stages, and can effectively identify coma patients to avoid urinary tract infections.
