Description

Technical Field

[0001] The present invention relates to the technical field of stoma care, and in particular to a stoma chassis intelligent monitoring system. Background Art

[0002] Ostomy surgery is a common medical procedure used to treat various digestive tract diseases, such as colon cancer and rectal cancer. After surgery, patients need to install an ostomy bag on their abdomen to collect excrement. The ostomy base is an important component that connects the ostomy bag to the patient's skin. Its stability and comfort directly affect the patient's daily quality of life.

[0003] Currently, the stoma base plate fixation methods on the market mainly rely on sticking materials such as tape or adhesives. However, this fixation method has the following problems:

[0004] When used for a long time or during strenuous exercise, the adhesive material can easily loosen, causing the stoma base to fall off and increasing the risk of infection.

[0005] Patients need to regularly check and manually adjust the position and pressure of the stoma base plate, which increases the difficulty and inconvenience of care.

[0006] Based on this, there is an urgent need for an intelligent monitoring system for the stoma base, which can achieve stable fixation of the stoma base while automatically adjusting the pressure on the stoma base, thereby improving the patient experience. Summary of the invention

[0007] One of the purposes of the present invention is to provide an intelligent monitoring system for a stoma base plate, which can achieve stable fixation of the stoma base plate and automatic adjustment of the pressure exerted on the stoma base plate, thereby improving the patient's experience.

[0008] In order to achieve the above-mentioned object, a stoma chassis intelligent monitoring system is provided, comprising a chassis device arranged on a patient and a service end;

[0009] The server includes:

[0010] A data acquisition module, used for collecting sensor data corresponding to sensors arranged in the stoma chassis in the chassis device, wherein the sensor data includes current pressure data corresponding to a pressure sensor arranged at the bottom of the stoma chassis, current temperature data corresponding to a temperature sensor arranged on the inner wall of the stoma chassis, and current humidity data corresponding to a humidity sensor;

[0011] It is also used to collect gyroscope data corresponding to the gyroscope provided on the chassis device;

[0012] The abnormality judgment module is used to judge whether the pressure of the stoma base plate fixed by the patient at the current moment is abnormal based on the collected current pressure data and the preset preset pressure range, and form a corresponding abnormality judgment result;

[0013] A body position determination module, for determining the current body position data corresponding to the patient at the current moment according to the collected gyroscope data and a preset body position determination strategy when the abnormal judgment result is that the pressure of the stoma base plate fixed to the patient at the current moment is abnormal;

[0014] An analysis module is used to match the reasonable pressure value corresponding to the patient's current body position data at the current moment from the stoma bottom plate pressure value corresponding table based on the current body position data, the current pressure data, the current temperature data and the current humidity data, based on the corresponding stoma bottom plate pressure value corresponding table in the database, wherein each pressure value in the stoma bottom plate pressure value corresponding table is within a preset pressure range;

[0015] A strategy generation module is used to generate a telescopic adjustment scheme corresponding to the automatic telescopic mechanism in the chassis device at the current moment based on the current pressure data and the matched reasonable pressure value corresponding to the current body position data of the patient at the current moment, based on a preset adjustment scheme generation strategy, and the telescopic adjustment scheme includes a telescopic speed and a telescopic length;

[0016] A sending module, used for feeding back the generated telescopic adjustment scheme to the chassis device;

[0017] The chassis device comprises:

[0018] A fixed waist belt, wherein a pressing portion is provided in the middle of the fixed waist belt; the pressing portion is used to press and fix the stoma base plate fixed on the patient;

[0019] A pressing portion for pressing the stoma base plate is provided in the middle of the fixing waist belt;

[0020] The automatic telescopic mechanism is arranged on the fixed waist belt and is used to automatically adjust the length of the fixed waist belt mounted on the patient according to the telescopic adjustment scheme sent by the service end according to the telescopic speed until the telescopic length is reached.

[0021] Technical principles and effects of this scheme: In this scheme, the stoma chassis in the chassis device is first installed on the patient's stoma, and then the corresponding pressure sensor, temperature sensor and humidity sensor are arranged on the stoma chassis. The pressure on the stoma chassis and the temperature and humidity inside the stoma chassis are monitored by these sensors. At the same time, the patient's body position changes are monitored by a gyroscope arranged on the stoma chassis to form corresponding gyroscope data.

[0022] Afterwards, the data corresponding to each sensor and gyroscope in the chassis device are collected through the data acquisition module, and the current pressure data collected is combined with the preset pressure range to determine whether the pressure of the stoma chassis fixed at the stoma of the patient at the current moment is abnormal. That is, if the current pressure data is not within the preset pressure range, it is a pressure abnormality. Once the pressure abnormality is detected, the current body position data corresponding to the patient at the current moment will be quickly identified based on the collected gyroscope data and the preset body position determination strategy. Then, based on the current body position data, current pressure data, current temperature data and current humidity data, based on the corresponding stoma chassis pressure value correspondence table in the database, the reasonable pressure value corresponding to the patient's current body position data at the current moment is matched from the stoma chassis pressure value correspondence table, and each pressure value in the stoma chassis pressure value correspondence table is within the preset pressure range.

[0023] Finally, according to the current pressure data and the matched reasonable pressure value corresponding to the current patient's current body position data, based on the preset adjustment plan generation strategy, the telescopic adjustment plan corresponding to the automatic telescopic mechanism in the chassis device at the current moment is generated. Through the telescopic adjustment plan, the automatic telescopic mechanism is controlled, and the automatic telescopic mechanism will automatically adjust the length of the fixed belt fixed on the patient according to the corresponding adjustment speed until the telescopic length is reached.

[0024] 1. In this solution, multiple sensors and gyroscopes are set on the stoma base, so as to realize real-time monitoring of the pressure, temperature and humidity of the stoma base on the patient's stoma. Through timely monitoring of pressure data and abnormal judgment of pressure data, timely detection of pressure abnormalities is achieved.

[0025] 2. In this scheme, the chassis device cooperates with the stoma chassis and the fixed belt. While the stoma chassis itself is fixed, the stoma chassis is further fixed by the fixed belt. At the same time, a corresponding automatic telescopic mechanism is set on the fixed belt. The setting of the automatic telescopic mechanism can ensure the automatic adjustment of the pressure at the stoma chassis.

[0026] 3. Through the cooperation of the analysis module and the strategy generation module in the server, when there is an abnormal pressure on the stoma base, the telescopic adjustment plan of the automatic telescopic mechanism corresponding to the patient in the current position can be quickly determined, so as to adjust the pressure on the stoma base, ensure the rationality of the pressure on the patient's stoma, improve the patient's comfort and improve the reliability of the stoma base.

[0027] Furthermore, the preset posture determination strategy includes the following steps:

[0028] S10, according to the collected gyroscope data, retrieve the current gyroscope data collected at the current moment and each historical gyroscope data within a preset time interval;

[0029] S20, inputting the current gyroscope data and each historical gyroscope data into a preset attitude angle calculation model, and outputting the current attitude angle corresponding to the gyroscope data at the current moment and the historical attitude angle corresponding to each historical gyroscope data;

[0030] S30, according to the current posture angle corresponding to the current moment, selecting the historical posture angle corresponding to the previous moment and the historical posture angle corresponding to the previous moment from each historical posture angle, and calculating the corresponding posture angle change rate based on the posture angle change rate calculation formula;

[0031] The attitude angle change rate calculation formula is:

[0032]

[0033] Where ∝ is the rate of change of attitude angle, θ(t i ) is time t i The corresponding attitude angle;

[0034] S40, calculating the corresponding attitude angle fluctuation degree according to the current attitude angle and each historical attitude angle based on a preset attitude angle fluctuation calculation formula;

[0035] The calculation formula of the attitude angle fluctuation is:

[0036]

[0037] In the formula, B is the attitude angle fluctuation, and N is the total number of corresponding attitude angles;

[0038] S50, according to the calculated posture angle change and posture angle fluctuation, based on a preset weight ratio, the corresponding body position change is calculated, and it is determined whether the body position change is less than a preset body position change threshold, if so, it is determined that the patient's body position remains unchanged at the current moment, if not, S1 is re-executed at the next moment;

[0039] S60: When the judgment result is that the patient's body position remains unchanged at the current moment, determine the current body position data corresponding to the patient at the current moment according to the current posture angle corresponding to the gyroscope data at the current moment.

[0040] Beneficial effect: In the present scheme, firstly, based on the gyroscope data corresponding to the current moment, with the current moment as the starting point and the preset time interval as the interval, other historical gyroscope data within the preset time interval are retrieved, and then these gyroscope data are input into the preset attitude angle calculation model to calculate the attitude angle at each moment, and then the attitude angle at each moment calculated is used to calculate the attitude angle change rate and the attitude angle fluctuation degree, respectively. In the process of calculating the attitude angle change rate, the attitude angle change rate corresponding to the current moment is accurately and reliably calculated by the attitude angles corresponding to the current moment, the previous moment and the previous moment, and the calculation of the attitude angle fluctuation degree integrates all the attitude angles at the current moment and the preset time interval, so as to realize the reliable and comprehensive calculation of the attitude angle fluctuation degree, and further improve the calculation accuracy of the subsequent body position change degree.

[0041] Furthermore, the preset adjustment scheme generation strategy includes the following steps:

[0042] S100, retrieving the treatment plan corresponding to the patient and the habit data corresponding to the patient from the database;

[0043] S200, identifying a preset treatment time period and a preset sleep time period corresponding to the patient according to the patient's treatment plan and habit data;

[0044] S300, according to the current body position data, retrieve the historical body position data corresponding to the patient, and judge in order of time interval from small to large whether the similarity between the current body position data and each historical body position data is greater than a preset similarity threshold, if so, judge the next historical body position data, until the similarity between a certain historical body position data and the current body position data is less than or equal to the preset similarity threshold, at which time, determine the time corresponding to the previous historical body position data, and calculate the duration of the patient in the body position corresponding to the current body position data based on the current time corresponding to the current body position data;

[0045] S400, according to the calculated body position duration corresponding to the current body position data, and the preset treatment time period and preset sleep time period corresponding to the patient, the patient state corresponding to the current body position data at the current moment; the patient state includes a sleep state, a treatment state, and a daily activity state;

[0046] S500, calculating the pressure difference between the current pressure data and the reasonable pressure value according to the current pressure data corresponding to the patient at the current moment and the matched reasonable pressure value corresponding to the current body position data of the patient at the current moment, and determining the telescopic length of the fixed waist belt to be adjusted;

[0047] S600, when the patient is in a sleeping state, retrieving a preset extension and retraction speed from a database;

[0048] S700, when the patient is in a treatment state, sending a first request instruction to the medical end, and when the medical end receives the first request instruction, the medical staff independently sets the telescopic speed, and feeds back the independently set telescopic speed to the service end;

[0049] S800. When the patient is in a daily activity state, a second request instruction is sent to the patient end. When the patient end receives the second request instruction, it independently sets the corresponding telescopic speed according to the preset telescopic speed adjustable range, and feeds back to the server end.

[0050] Beneficial effect: In this scheme, through the entire treatment plan and habit data corresponding to the patient in the hospital, the preset treatment time periods and preset sleep time periods corresponding to the patient in the hospital can be quickly identified, and then the posture duration corresponding to the current posture data is calculated, so as to quickly and accurately judge the patient's state corresponding to the current moment. Specifically, the current posture data and the historical posture data are judged in the order of time interval from small to large for similarity, so as to identify the time interval that is the same as the current posture data, so as to complete the calculation of posture duration. Then, when different patient states are identified, the strategies corresponding to each patient state are used to determine the extension speed according to the different patient states, so as to realize the personalized and scientific adjustment of the belt extension. For example, when the patient is in the sleeping state, the corresponding preset extension speed may be slower and more stable than the other two states, which greatly reduces the influence of the fixed belt on the patient's sleep during the adjustment process, and realizes the rationalization of the belt adjustment.

[0051] Furthermore, the fixed waist belt comprises a fixed waist belt body, the pressing portion is arranged in the middle of the fixed waist belt body; a shell is fixed at one end of the fixed waist belt body, the automatic telescopic mechanism is arranged in the shell, and the shell is provided with a through hole along the length direction of the fixed waist belt body for the end of the fixed waist belt body away from the shell to extend into;

[0052] The automatic telescopic mechanism includes a controller, a communication module, a motor, and a transmission mechanism for driving the end of the fixed belt body away from the shell to move back and forth. The controller is electrically connected to the communication module and the motor respectively. The controller is used to receive the telescopic adjustment plan fed back by the service end through the communication module; the end of the fixed belt body away from the shell is connected to the motor through the transmission mechanism.

[0053] Beneficial effects: In this solution, the length of the belt can be automatically adjusted according to the needs of the user through the built-in automatic telescopic mechanism, which improves the convenience and adaptability of use. The design of the pressing part can provide users with a better wearing experience, especially reducing discomfort when wearing for a long time. BRIEF DESCRIPTION OF THE DRAWINGS
