Description
Technical Field
[0001] The present application relates to the field of medical care technology, and in particular to a temperature-controlled feed injector for treating radiation oral mucositis and related methods. Background Art
[0002] Radiation-induced oral mucositis is a common complication in patients with head and neck cancer who undergo radiotherapy. Radiation damages the epithelial cells of the oral mucosa, triggering an inflammatory response that manifests as redness, swelling, ulcers, and pain in the mucosa. In severe cases, it can affect eating and nutritional intake. Patients with radiation-induced oral mucosal damage, decreased saliva, and painful swallowing require special eating methods to reduce irritation and ensure nutrition.

The food storage part is connected to the back of the patient's mouth through a conveying device, and the liquid food is delivered through the feeding channel. The end design of the conveying device is adapted to the oral structure to avoid direct contact with the ulcer surface, thereby reducing the risk of contamination of the patient's oral wound. The feeding device is squeezed by the feeding device to provide power, and the speed and flow rate of the liquid food entering the oral cavity from the food storage part through the feeding channel are controlled to achieve controllable push (avoiding the problem of uneven speed of traditional syringe push). The oral pressure data and throat sound data are monitored by the acquisition part, and it is judged in real time whether the patient has the risk of choking or aspiration (such as a sudden increase in throat pressure and the occurrence of choking sounds), and a feedback signal is provided for the start and stop of the feeding device to reduce the possibility of aspiration in the patient.
[0007] In a second aspect, an embodiment of the present application provides a method for feeding with a temperature-controlled feeding device, which is applied to the temperature-controlled feeding device for treating radiation oral mucositis described in the first aspect above, and the method comprises: Acquire oral information in real time; wherein the oral information includes oral pressure data and throat sound data collected at a preset collection frequency, the oral pressure data reflecting the pressure in the patient's mouth during swallowing, and the throat sound data reflecting the sound near the patient's throat when swallowing; Obtaining analysis information based on the oral information; wherein the analysis information includes pressure confirmation information and sound confirmation information, the pressure confirmation information including information reflecting whether the pressure in the patient's oral cavity is normal, and the sound confirmation information including information reflecting whether the sound of the patient's throat when swallowing is normal; Control information is obtained based on the analysis information; wherein the control information is used to control the feeding device.

[0019] Radiation-induced oral mucositis is a common complication in patients with head and neck cancer who undergo radiotherapy. Radiation damages the epithelial cells of the oral mucosa, triggering an inflammatory response that manifests as redness, swelling, ulcers, and pain in the mucosa. In severe cases, it can affect eating and nutritional intake. Patients with radiation-induced oral mucosal damage, decreased saliva, and painful swallowing require special eating methods to reduce irritation and ensure nutrition.
[0020] Currently, patients undergoing head and neck radiotherapy are often fed via nasogastric tubes or using a long-handled curved spoon and a 5ml syringe for push-feeding of liquid food. The nasal and pharyngeal mucosa are fragile after radiotherapy, and prolonged compression from a nasogastric tube can easily lead to mucosal erosion, ulceration, and even bleeding. Approximately 15%-30% of patients experience nasal mucosal damage, requiring tube discontinuation in severe cases. Furthermore, nasogastric tubes impede the natural swallowing of saliva, and reflux into the mouth can lead to aspiration pneumonia. The risk of aspiration in patients undergoing head and neck radiotherapy is 2-3 times higher than in the general population. Long-term reliance on nasogastric feeding can lead to disuse atrophy of the swallowing muscles, delaying the recovery of oral feeding function. For patients on nasogastric feeding for more than four weeks, the success rate of spontaneous swallowing is reduced by 40%. Using a long-handled curved spoon and syringe for push-feeding of liquid food can contaminate oral wounds and worsen oral infections. Furthermore, the flow of food cannot be paced according to the patient's physiological needs, which can easily cause choking or aspiration. Furthermore, the patient needs to be accompanied by medical staff throughout the feeding process, resulting in a waste of human resources.
[0021] Based on this, in order to improve the technical problem that feeding with a nasogastric tube or using a long-handled elbow spoon and a 5ml syringe to push liquid food can easily cause the patient to choke or aspirate, which is not conducive to the patient's recovery, the embodiment of the present application provides the following solution.
[0022] See also Figure 1 The embodiment of the present application provides a temperature-controlled feeding device 100 for treating radiation-induced oral mucositis. The temperature-controlled feeding device 100 for treating radiation-induced oral mucositis includes a food storage portion 10, a feeding portion 20, a conveying device 21, a feeding device 22, and a collection portion 30, wherein: The food storage portion 10 has a food storage space 113, and the food storage space 113 is used to store liquid food.
[0023] The feeding portion 20 includes a conveying device 21 and a feeding device 22. One end of the conveying device 21 is arranged on the food storage portion 10, and the other end is used to be placed at the back of the patient's mouth. The conveying device 21 has a feeding channel connected to the food storage space 113. The feeding device 22 is arranged on the food storage portion 10 and is used to squeeze the conveying device 21 to deliver the liquid food in the food storage space 113 to the patient's mouth through the feeding channel.
[0024] The collecting portion 30 is provided on the delivery device 21 and is close to an end for placement in the patient's oral cavity, and is used to monitor oral pressure data and throat sound data.
[0025] It can be understood that the food storage portion 10 is a storage device that can provide a closed food storage space 113 and maintain the temperature of the stored liquid for a certain period of time (1-2 hours). For example, the material of the food storage portion 10 can be medical-grade transparent silicone (high temperature resistant to 120°C), with a capacity of 200-300ml, with scale lines, and also includes a constant temperature heating device (electric heating jacket, electric heating wire, etc.) or phase change material (paraffin-based phase change material, fatty acid phase change material, etc.) for maintaining the temperature of liquid food, etc., but is not limited to this.
[0026] The delivery device 21 is a device that can guide the liquid food in the food storage space 113 to the patient's mouth. For example, the delivery device 21 can be a medical-grade silicone tube with an inner diameter of 4-6 mm and a length of 30-50 cm, but is not limited thereto.
[0027] The feeding device 22 is a device that can control the speed and flow rate (10-20 ml / min) of liquid food from the food storage part 10 into the oral cavity through the feeding channel. For example, the feeding device 22 can be a motor-driven peristaltic pump, a knob-controlled valve, etc., but is not limited to this.
[0028] The collecting unit 30 is a device that can monitor oral pressure data and throat sound data in real time. For example, the collecting unit 30 may include a pressure sensor (strain sensor, piezoelectric sensor, etc.) and a sound sensor (micro microphone, flexible acoustic sensor, etc.), etc., but is not limited to this. Among them, the pressure sensor can be arranged on the delivery device 21 and close to one end for placement in the patient's mouth, and the sound sensor can be attached to the patient's throat or located near the patient's throat, etc., but is not limited to this.
[0029] As can be seen from the above, the temperature-controlled feed injector 100 for radiation-induced oral mucositis provided in the embodiment of the present application stores liquid food through the food storage portion 10 and keeps it warm for a short period of time, thereby preventing the liquid food from spoiling or being contaminated. The food storage portion 10 is connected to the back of the patient's mouth by the delivery device 21, and the liquid food is delivered through the feeding channel. The end design of the delivery device 21 is adapted to the oral structure to avoid direct contact with the ulcer surface, thereby reducing the risk of contamination of the patient's oral wound surface. The feeding device 22 squeezes the delivery device 21 to provide power, controlling the speed and flow rate of the liquid food from the food storage portion 10 through the feeding channel into the oral cavity, thereby achieving controllable delivery (avoiding the uneven speed problem of traditional syringe injection). The acquisition unit 30 monitors oral pressure data and throat sound data, and determines in real time whether the patient is at risk of choking or aspiration (such as a sudden increase in throat pressure or a choking sound). Feedback signals are provided for starting and stopping the feeding device 22, thereby reducing the possibility of aspiration.
[0030] Optionally, the temperature-controlled feeding device 100 may further include a control unit, which is communicatively connected to the collection unit 30 and the feeding device 22 , and is used to control the feeding device 22 according to the oral pressure data and throat sound data collected by the collection unit 30 .
[0031] In some embodiments, please refer to Figure 1 and Figure 2 The food storage portion 10 includes a food storage mechanism 11 , a sealing member 12 and a direction limiting device 13 .
[0032] The food storage mechanism 11 includes a food storage accommodating space 113 and a food storage hole communicating with the food storage accommodating space 113 .
[0033] The sealing member 12 is detachably provided on the food storage mechanism 11 for sealing the food storage hole. The sealing member 12 has a liquid food passage communicating with the food storage space 113 .
[0034] The direction limiting device 13 is provided on the sealing member 12 and is partially located in the liquid food passage, and is used to prevent the liquid food in the feeding passage from entering the food storage space 113 through the liquid food passage.
[0035] It can be understood that the food storage mechanism 11 is a storage device that can provide a storage space 113 for storing liquid food and maintain the temperature of the stored liquid for a certain period of time (1-2 hours). For example, the material of the food storage mechanism 11 can be medical-grade transparent silicone (high temperature resistant to 120°C), with a capacity of 200-300ml, with scale lines, and also includes a constant temperature heating device (electric heating sleeve, electric heating wire, etc.) or phase change material (paraffin-based phase change material, fatty acid phase change material, etc.) for maintaining the temperature of liquid food, etc., but is not limited to this.
[0036] The seal 12 is a device that seals the food storage hole to prevent liquid food from leaking and connects the food storage space 113 to the food injection channel through the liquid food channel. For example, the seal 12 may be made of, but is not limited to, medical-grade silicone or engineering plastic. The seal 12 may be connected to the food storage mechanism 11 via a threaded or snap-fit structure.
[0037] The direction restriction device 13 is a device that allows liquid food in the food storage space 113 to pass through the liquid food channel and enter the feeding channel, while strictly preventing the liquid food in the feeding channel from flowing back into the food storage space 113, thereby preventing cross contamination and the risk of aspiration. For example, the direction restriction device 13 can be a duckbill one-way valve, a ball one-way valve, etc., but is not limited thereto.
[0038] With this arrangement, liquid food is stored and kept warm for a short period of time through the food storage mechanism 11, preventing it from spoiling or becoming contaminated. The removable connection of the seal 12 to the food storage mechanism 11 facilitates cleaning and prevents residual liquid food from breeding bacteria. The direction limiting device 13 quickly closes and blocks the liquid food passage when the liquid food in the feeding channel tends to flow in the opposite direction due to the patient's coughing, swallowing, or a pause in the feeding device 22. This prevents liquid food that has already entered the feeding channel from flowing back into the food storage space 113 (preventing the clean liquid food in the food storage space 113 from being contaminated by oral bacteria).
[0039] In some embodiments, please refer to Figure 1 and Figure 2 The food storage mechanism 11 includes an inner food storage component 111 and an outer food storage component 112 .
[0040] The internal food storage part 111 has a food storage space 113; and The outer food storage part 112 is provided on the inner food storage part 111 and has a food storage hole; The inner food storage part 111 and the outer food storage part 112 have a gap for filling the phase change material, and the sealing part 12 is detachably provided on the outer food storage part 112 .
[0041] It is understood that the inner food storage member 111 directly supports the food storage space 113 and is in direct contact with the liquid food. For example, the material of the inner food storage member 111 can be, but is not limited to, medical-grade transparent silicone, polytetrafluoroethylene, etc., and the capacity of the inner food storage member 111 can be, but is not limited to, 200 ml, 300 ml, etc.
[0042] The outer food storage member 112 provides mounting support for the inner food storage member 111, forms a phase change material filling area through the gap between the outer food storage member 112 and the inner food storage member 111, and is connected to the sealing member 12 through the food storage hole. For example, the material of the outer food storage member 112 can be medical grade transparent silicone, PP plastic, etc., but is not limited thereto.
[0043] The phase change material can be a paraffin-based phase change material, a fatty acid phase change material, etc., but is not limited thereto. The external food storage member 112 can also be coated with a temperature-sensitive material or affixed with a temperature-sensitive label, and the coating or label changes color with temperature to provide an intuitive temperature warning.
[0044] With this arrangement, liquid food is stored in the inner food storage part 111, and the temperature is maintained for 1-2 hours (short-term heat preservation (15-40°C) or cold preservation) by the phase change material located in the gap between the inner food storage part 111 and the outer food storage part 112, thereby preventing the nutrient solution (liquid food) from deteriorating.
[0045] Exemplarily, the inner food storage component 111 and the outer food storage component 112 may also have air filter holes for balancing the air pressure in the food storage space 113 .
[0046] In some embodiments, please refer to Figure 1 and Figure 2 The conveying device 21 includes a conveying member 211 and an adapter member 212 .
[0047] One end of the conveying member 211 is disposed on the food storage portion 10 , and the conveying member 211 has a food injection channel.
[0048] The adapter 212 is rotatably disposed on the other end of the conveying member 211. The adapter 212 is provided with at least two anti-blocking side holes communicating with the feeding channel. The adapter 212 is used to be placed at the back of the patient's mouth.
[0049] The feeding device 22 is used to squeeze the conveying member 211 , and the collecting portion 30 is disposed on the adapter 212 .
[0050] It is understood that the conveyor member 211 is a conduit that connects the food storage portion 10 and the adapter 212, and achieves stable delivery of liquid food through the feeding channel. For example, the material of the conveyor member 211 can be food-grade silicone, platinum-cured silicone, etc., but is not limited to these. The inner diameter of the conveyor member 211 can be 4-6 mm, and the length can be 30-50 cm, etc., but is not limited to these. The shape of the feeding device 22 can be curved to fit the contours of the oral cavity. The conveyor member 211 can be detachably connected to the sealing member 12, thereby facilitating replacement of the conveyor member 211 after prolonged use.
[0051] The adapter 212 is a device placed directly at the back of the patient's mouth. It disperses the liquid and food outlet through the anti-blocking side holes and is designed to rotate to adapt to changes in the oral cavity. For example, the adapter 212 can be made of, but is not limited to, TPE soft rubber or food-grade silicone. The adapter 212 can have a hard support ring inside to prevent deformation caused by the patient's bite. The collection unit 30 can be located on the adapter 212 or on the delivery member 211.
[0052] With this arrangement, liquid food in the food storage portion 10 is squeezed by the feeding device 22, flows through the feeding channel of the delivery member 211, and then flows to the adapter 212. It is then ejected simultaneously through at least two anti-blocking side holes in the adapter 212 and the end of the delivery member 211 located within the oral cavity, evenly distributing the liquid food to the back of the mouth (avoiding single-point impact) and dispersing the pressure of feeding. The portions of the delivery member 211 and adapter 212 located within the oral cavity have rounded corners (smooth, no sharp edges) to prevent irritation to the patient's mouth. By rotatably connecting the adapter 212 to the delivery member 211, it naturally rotates with the angle of the oral cavity when the patient swallows or moves his head, avoiding mucosal friction caused by rigid fixation.
[0053] In some embodiments, please refer to Figure 1 and Figure 2The feeding device 22 includes a mounting member 221 , an extruding member 222 and an extruding driving member 223 .
[0054] The mounting member 221 is disposed on the food storage portion 10 and has an installation accommodation space, and a portion of the conveying device 21 is located in the installation accommodation space.
[0055] The extrusion member 222 is located in the installation accommodation space and is rotatably disposed on the installation member 221 . An extrusion channel is formed between the extrusion member 222 and the installation member 221 , and a portion of the conveying device 21 is located in the extrusion channel.
[0056] The extrusion driving member 223 is arranged on the mounting member 221, and the power output shaft of the extrusion driving member 223 is connected to the extrusion member 222. The extrusion driving member 223 is used to drive the extrusion member 222 to rotate to squeeze the conveying device 21 in the extrusion channel so as to extract the liquid food in the food storage space 113 into the feeding channel and deliver it to the patient's mouth.
[0057] It is understood that the mounting member 221 is capable of fixing the extrusion member 222 and the extrusion driving member 223, and constraining the position of the conveying member 211 by installing the accommodation space. For example, the material of the mounting member 221 can be engineering plastics, POM plastics, etc., but is not limited thereto.
[0058] The extrusion member 222 is a device that can squeeze the silicone tube of the delivery device 21 through rotational motion, and extract and push the liquid food by utilizing the elastic restoring force of the tube lumen. For example, the extrusion member 222 can be a roller structure made of engineering plastic or POM plastic, but is not limited thereto.
[0059] The extrusion drive 223 is a driving device that can provide rotational power to the extrusion member 222 and adjust the liquid food delivery speed by controlling the rotation speed. For example, the extrusion drive 223 can be a DC reduction motor, a servo motor, etc., but is not limited thereto.
[0060] With this arrangement, the extrusion driver 223 receives a control signal to drive the extrusion member 222 to rotate. The wheel surface of the extrusion member 222 cooperates with the U-shaped groove of the mounting member 221, generating a continuous extrusion force on the conveying member 211 passing through the extrusion channel. This causes the lumen of the conveying member 211 to close at the location where it is squeezed, while the lumen in front expands due to elastic recovery force. Under the action of negative pressure, liquid food is extracted from the food storage space 113. As the extrusion member 222 continues to rotate, the extrusion force moves axially along the conveying member 211, thereby pushing the liquid food at a uniform speed into the feeding channel and then into the patient's mouth through the anti-blocking side hole of the adapter 212. When the extrusion member 222 stops rotating, the liquid food in the feeding channel does not move.
[0061] For example, the control unit may be provided on the food storage portion 10 and be in communication with the extrusion drive member 223 and the collection portion 30 , and may be configured to control the extrusion drive member 223 to drive the extrusion member 222 to rotate.
[0062] See also Figure 3 The present application also provides a method for feeding with a temperature-controlled feeding device, which is applied to the temperature-controlled feeding device 100 for treating radiation oral mucositis described in any of the above embodiments. The method for feeding with a temperature-controlled feeding device includes: Acquire oral information in real time; oral information includes oral pressure data and throat sound data collected at a preset frequency. Oral pressure data reflects the pressure in the patient's mouth during swallowing, and throat sound data reflects the sound near the patient's throat when swallowing. Obtaining analysis information based on the oral information; wherein the analysis information includes pressure confirmation information and sound confirmation information, the pressure confirmation information including information reflecting whether the pressure in the patient's oral cavity is normal, and the sound confirmation information including information reflecting whether the sound of the patient's throat when swallowing is normal; Control information is obtained based on the analysis information; wherein the control information is used to control the feeding device 22.
[0063] As can be seen from the above, the temperature-controlled feeding device feeding method provided in the embodiment of the present application achieves real-time tracking of the patient's swallowing process by acquiring oral information, including oral pressure data and throat sound data collected at a preset collection frequency, providing data support for subsequent determination of the swallowing status. Then, by obtaining analysis information, including pressure confirmation information and sound confirmation information, based on the oral information, a comprehensive assessment of the patient's swallowing status is formed, ensuring that abnormal swallowing function can be promptly identified. Finally, based on the analysis information, control information for controlling the feeding device 22 is obtained, achieving adaptive matching of the feeding process and the patient's swallowing status, improving the safety issues of traditional feeding methods, and reducing the possibility of patient aspiration.
[0064] In order to better understand the feeding method of the temperature-controlled feeding device provided in the embodiment of the present application, the specific implementation process of the feeding method of the temperature-controlled feeding device provided in the embodiment of the present application is exemplarily introduced below.
[0065] Figure 3 A schematic flow chart of a feeding method using a temperature-controlled feeding device provided in an embodiment of the present application is shown. The feeding method using a temperature-controlled feeding device includes: S100, obtaining oral information in real time; wherein, the oral information includes oral pressure data and throat sound data collected at a preset collection frequency, the oral pressure data reflects the pressure in the patient's oral cavity during swallowing, and the throat sound data reflects the sound near the patient's throat when swallowing.
[0066] It is understood that the preset collection frequency can be, but is not limited to, 0.1s / time, 0.2s / time, etc. The method for collecting oral pressure data and throat sound data can be, but is not limited to, receiving data collected in real time by the collection unit 30 at the preset collection frequency, or receiving data transmitted by the doctor, etc. Real-time acquisition of oral information enables real-time tracking of the patient's swallowing process, providing data support for subsequent determination of swallowing status.
[0067] S200, obtaining analysis information based on oral information; wherein the analysis information includes pressure confirmation information and sound confirmation information, the pressure confirmation information includes information reflecting whether the pressure in the patient's oral cavity is normal, and the sound confirmation information includes information reflecting whether the sound of the patient's throat when swallowing is normal.
[0068] It can be understood that the way to obtain analysis information based on oral information can be that the doctor first guides the patient to perform multiple normal swallows and obtains the oral pressure data and throat sound data collected during each swallowing process, and then obtains the analysis swallowing time, analysis baseline pressure, analysis peak pressure and analysis pressure rise rate corresponding to the oral pressure data collected during each swallowing process, and the analysis main frequency and analysis peak amplitude corresponding to the throat sound data collected during each swallowing process, and then adds up each analysis swallowing time and takes the average value to obtain the swallowing time, adds up each analysis baseline pressure and takes the average value to obtain the baseline pressure, adds up each analysis peak pressure and takes the average value to obtain the initial peak pressure, adds up each analysis pressure rise rate and takes the average value to obtain the initial pressure rise rate, adds up each analysis main frequency and takes the average value to obtain the The initial dominant frequency is obtained by taking the average value, and the initial peak amplitude is obtained by adding up the individual analyzed peak amplitudes and taking the average value. Then, the monitoring peak pressure and the monitoring pressure rise rate are obtained based on the oral pressure data collected during the swallowing time acquired in real time. The monitoring dominant frequency and the monitoring peak amplitude are obtained based on the throat sound data collected during the swallowing time acquired in real time. Then, the monitoring peak pressure is compared with the initial peak pressure, and the monitoring pressure rise rate is compared with the initial pressure rise rate to obtain pressure confirmation information. The monitoring dominant frequency is compared with the initial dominant frequency, and the monitoring peak amplitude is compared with the initial peak amplitude to obtain analysis information. Then, the pressure confirmation information and the sound confirmation information are confirmed as analysis information. Alternatively, the oral information may be sent to a doctor and then the doctor's transmitted data may be received, etc., but is not limited to this. Obtaining analysis information based on oral information can form a comprehensive assessment of the patient's swallowing status, ensuring that abnormal swallowing function of the patient can be identified in a timely manner.
[0069] In one possible implementation, see Figure 4 S200: Obtaining analysis information based on oral information, including: S210, obtaining initial information; wherein the initial information includes initial pressure information and initial sound information, the initial pressure information is the pressure data collected by the collection unit 30 from the start of feeding to the completion of swallowing when the doctor guides the patient to perform at least two normal swallowing movements, and the initial sound information is the sound data collected by the collection unit 30 during each swallowing process of the patient when the doctor guides the patient to perform at least two normal swallowing movements.
[0070] It is understood that the initial information can be obtained by receiving data transmitted by the acquisition unit 30 or by receiving data transmitted by a physician, but is not limited thereto. Because patients with radiation-induced oral mucositis exhibit significant individual differences in swallowing function (e.g., varying degrees of mucosal damage, pain tolerance, and swallowing habits), universal "normal swallowing standards" (e.g., fixed pressure ranges and uniform sound characteristics) may not be applicable to specific patients. Obtaining initial information can establish an "individualized normal baseline," avoiding the limitations of universal standards and providing an accurate comparative basis for assessing a patient's swallowing status.
[0071] S220, pressure judgment information and sound judgment information are obtained based on the initial information; wherein, the pressure judgment information includes swallowing time, baseline pressure, initial peak pressure and initial pressure rise rate, the pressure judgment information reflects the relationship between pressure and time when the patient squeezes the liquid food into the pharyngeal cavity, the swallowing time reflects the time from the start of food injection to the completion of swallowing by the patient, the baseline pressure reflects the oral pressure of the patient when he / she has not swallowed, the initial pressure rise rate reflects the rate at which the pressure in the patient's mouth rises from the baseline pressure to the initial peak pressure corresponding to the initial pushing stage, and the sound judgment information includes swallowing time, initial main frequency and initial peak amplitude.
[0072] It is understood that the pressure judgment information obtained based on the initial information can be obtained by manually calculating the pressure data collected during each swallowing process or automatically calculating the pressure data analysis module to obtain the corresponding analyzed swallowing time, analyzed baseline pressure, analyzed peak pressure, and analyzed pressure rise rate, and then adding and averaging the corresponding data in the initial pressure information obtained during each swallowing process to obtain the swallowing time, baseline pressure, initial peak pressure, and initial pressure rise rate. Alternatively, the pressure data collected during each swallowing process can be sent to the doctor and then the doctor receives the data transmitted by the doctor, etc., but is not limited to this. The sound judgment information obtained based on the initial information can be obtained by automatically extracting multiple analyzed peak amplitudes from the time domain waveform of the sound data collected during each swallowing process through the sound data analysis model, then Fourier transforming the sound data collected during each swallowing process to obtain multiple frequency domain signals, and then obtaining multiple analyzed main frequency frequencies based on each frequency domain signal. The analysis peak amplitudes are added and averaged to obtain the initial peak amplitude, and the analysis main frequency frequencies are added and averaged to obtain the initial main frequency. Alternatively, the sound data collected during each swallowing process can be sent to the doctor and then the doctor receives the data transmitted by the doctor, etc., but is not limited to this. Obtaining pressure judgment information and sound judgment information based on the initial information can convert the "original normal swallowing data" into "quantifiable and comparable benchmark indicators", providing a basis for subsequent accurate identification of swallowing abnormalities.
[0073] S230: Confirm the oral pressure data during the swallowing time monitored in real time as pressure analysis information, and confirm the throat sound data during the swallowing time as sound analysis information.
[0074] It can be understood that by intercepting data during swallowing, the intercepted data (pressure analysis information and sound analysis information) can be effectively compared with the data during normal swallowing (pressure judgment information and sound judgment information), ensuring that the real-time monitoring data and the baseline data are aligned in the "time range" and avoiding logical confusion due to ambiguous analysis scope.
[0075] S240: Obtain pressure confirmation information based on the pressure analysis information and the pressure judgment information.
[0076] It is understood that pressure confirmation information can be obtained based on pressure analysis information and pressure judgment information by first confirming whether the overall patterns of the pressure analysis information (real-time monitoring data) and the pressure judgment information (personalized benchmark) are similar (for example, whether the pressure-time curves of the two have similar upward trends, peak positions, and fallback characteristics). If the patterns are similar, specific indicators (monitoring peak pressure, monitoring pressure rise rate) are further extracted and compared with the benchmark range (initial peak pressure ±10%, initial pressure rise rate ±10%). Only when both the monitoring peak pressure and the monitoring pressure rise rate fall within the benchmark range is the pressure determined to be "normal." When either indicator falls outside the range, the pressure is determined to be "abnormal." Alternatively, the pressure analysis information and pressure judgment information may be sent to a physician and then the physician's transmitted data may be received, etc., but is not limited to this. Obtaining pressure confirmation information based on pressure analysis information and pressure judgment information enables personalized judgment based on the "patient's own benchmark," eliminating interference from individual differences, and converting real-time swallowing data into a safety status label that can guide feeding decisions.
[0077] In one possible implementation, see Figure 4 S240, obtaining pressure confirmation information based on the pressure analysis information and the pressure judgment information, including: S241, determining whether the pressure analysis information is similar to the pressure judgment information. If the pressure analysis information is similar to the pressure judgment information, obtaining the monitored peak pressure and the monitored pressure rising rate based on the pressure analysis information.
[0078] It is understood that the similarity between pressure analysis information and pressure determination information can be determined by, but is not limited to, feature point matching (extracting key feature points (e.g., peaks, valleys, inflection points) from the pressure curve and comparing their positions and values), curve morphology similarity algorithms (e.g., dynamic time warping (DTW) and segmented similarity comparison). Determining the similarity between pressure analysis information and pressure determination information involves determining the overall similarity between the pressure analysis information (real-time swallowing pressure data) and the pressure determination information (the patient's own normal pressure baseline). This reflects the consistency of the overall pressure change trends during swallowing (e.g., the curve shape from baseline to peak and then back down, and the time proportion of each phase). If the two are overall dissimilar (e.g., the baseline curve shows a rapid rise followed by a slow fall, while the real-time curve shows a slow rise followed by a sharp fall), this indicates a significant abnormality in the swallowing process (perhaps due to pain, a change in swallowing method, or the presence of pre-choking coughs), or the patient is not swallowing.
[0079] The method for obtaining the monitoring peak pressure based on the pressure analysis information can be a direct extreme value method (traversing all pressure data points in the pressure analysis information, screening out the point with the largest value and confirming its corresponding pressure value as the monitoring peak pressure), a sliding window denoising method (dividing the pressure data into fixed time windows (such as 100ms), calculating the average pressure in each window, and then extracting the maximum value from the smoothed curve), etc., but not limited to these.
[0080] The method for obtaining the monitoring pressure rise rate based on the pressure analysis information can be an average rise rate method (monitoring pressure rise rate = (monitoring peak pressure - baseline pressure) / (peak occurrence time - rise start time)), an instantaneous slope method (linear fitting is performed on the curve of the pressure rise stage (such as fitting the linear equation of the rising section by the least squares method) to obtain a linear equation, and the slope of the linear equation is the monitoring pressure rise rate), etc., but is not limited to these.
[0081] The monitored peak pressure and the monitored pressure rise rate obtained based on the pressure analysis information can provide a basis for subsequent steps.
[0082] For example, before obtaining the monitored peak pressure and the monitored pressure rise rate based on the pressure analysis information, the original pressure data of the pressure analysis information can be filtered (such as low-pass filtering to remove high-frequency noise), baseline drift can be removed (to eliminate the influence of sensor zero drift), etc., to enhance the accuracy of the calculation.
[0083] S242, determine whether the monitored peak pressure is within the initial peak pressure range, and determine whether the monitored pressure rise rate is within the initial pressure rise rate range; wherein, the initial peak pressure range is a range interval formed by taking the initial peak pressure as the benchmark and floating up and down by 10%, and the initial pressure rise rate range is a range interval formed by taking the initial pressure rise rate as the benchmark and floating up and down by 10%.
[0084] It is understandable that by setting the range of "10% fluctuation", space is left for normal physiological fluctuations during swallowing, avoiding frequent misjudgments due to excessive sensitivity.
[0085] For example, assuming the initial peak pressure is 40 mmHg, the initial peak pressure range is (40*0.9, 40*1.1) = (36 mmHg, 44 mmHg). Assuming the initial pressure rise rate is 10 mmHg / 0.1 s, the initial pressure rise rate range is (10*0.9, 10*1.1) = (9 mmHg / 0.1 s, 11 mmHg / 0.1 s).
[0086] S243, if the monitored peak pressure is within the initial peak pressure range, and the monitored pressure rise rate is within the initial pressure rise rate range, then pressure confirmation information is obtained reflecting that the pressure in the patient's mouth is normal; if the monitored peak pressure is not within the initial peak pressure range, and / or the monitored pressure rise rate is not within the initial pressure rise rate range, then pressure confirmation information is obtained reflecting that the pressure in the patient's mouth is abnormal.
[0087] It can be understood that the pressure is judged to be normal only when the monitored peak pressure is within the initial range and the monitored pressure rise rate is within the initial range. This requires that the swallowing force (peak pressure) be within the patient's own safety range (to avoid obstruction of liquid food delivery due to insufficient force, or pain caused by excessive force), and that the swallowing coordination (pressure rise rate) conform to the patient's normal rhythm (to avoid liquid food retention in the mouth due to too slow a rate, or uncontrolled delivery due to too fast a rate). Judging by dual indicators can provide clear and quantitative results for the swallowing pressure status (for example, if the patient's peak pressure is normal but the rise rate is too slow (out of range), the patient may be hesitant to swallow due to mucosal pain. In this case, it is still judged as abnormal to avoid missed judgments), providing a clear basis for subsequent feeding control.
[0088] S250: Obtain voice confirmation information based on the voice analysis information and the voice judgment information.
[0089] It is understood that the method for obtaining the sound confirmation information based on the sound analysis information and the sound judgment information may be to first obtain the monitored main frequency and monitored peak amplitude based on the sound analysis information, and then compare the monitored main frequency and monitored peak amplitude with the initial main frequency and initial peak amplitude respectively to obtain the sound confirmation information. Alternatively, the method may be to send the sound analysis information and the sound judgment information to the doctor and then receive data transmitted by the doctor, etc., but is not limited to this. Obtaining the sound confirmation information based on the sound analysis information and the sound judgment information can provide a basis for subsequent steps.
[0090] In one possible implementation, see Figure 4 S250, obtaining sound confirmation information based on the sound analysis information and the sound judgment information, including: S251, obtaining a monitoring main frequency and a monitoring peak amplitude based on the sound analysis information.
[0091] It can be understood that the method of monitoring the main frequency based on the sound analysis information can be spectrum analysis (converting the sound analysis information from the time domain waveform (the change of sound over time) into the frequency domain spectrum (energy distribution of different frequencies), and finding the frequency point with the highest energy (i.e., the main frequency)), or sending the sound analysis information to the doctor and then receiving the data transmitted by the doctor, etc., but is not limited to this.
[0092] The method of obtaining the monitoring peak amplitude based on the sound analysis information can be a direct extreme value method (traversing the time domain waveform of the sound analysis information, finding the point with the largest amplitude and confirming its value as the monitoring peak amplitude), or sending the sound analysis information to the doctor and then receiving the data transmitted by the doctor, etc., but is not limited to this.
[0093] Monitoring the main frequency and peak amplitude based on sound analysis information can provide an objective basis for judging whether swallowing is normal.
[0094] For example, before obtaining the monitoring main frequency and the monitoring peak amplitude based on the sound analysis information, the environmental noise (such as external noise) can be filtered through a bandpass filter to retain the effective frequency band of the throat sound.
[0095] S252, determine whether the monitored main frequency is within the initial main frequency range, and determine whether the monitored peak amplitude is within the initial peak amplitude range; wherein, the initial main frequency range is a numerical range formed by floating up and down 10% based on the initial main frequency, and the initial peak amplitude range is a numerical range formed by floating up and down 10% based on the initial peak amplitude.
[0096] Understandably, by setting a 10% fluctuation range, we allow for normal physiological fluctuations and reduce the possibility of misjudgment. The dominant frequency reflects the tonal characteristics of the sound, such as the low frequency of normal swallowing and the high frequency of coughing. Abnormal dominant frequency indicates a change in the airflow vibration pattern. The peak amplitude reflects the intensity characteristics of the sound (such as the steady volume of normal swallowing and the violent sound of obstruction). Abnormal peak amplitude indicates abnormal airflow vibration intensity.
[0097] For example, assuming the initial main frequency is 500 Hz, the initial main frequency range is (500*0.9, 500*1.1) = (450 Hz, 550 Hz). Assuming the initial peak amplitude is 50 dB, the initial peak amplitude range is (50*0.9, 50*1.1) = (45 dB, 55 dB).
[0098] S253, if the monitored main frequency is within the initial main frequency range, and the monitored peak amplitude is within the initial peak amplitude range, then sound confirmation information is obtained reflecting that the sound of the patient's throat when swallowing is normal; if the monitored main frequency is not within the initial main frequency range, and / or the monitored peak amplitude is not within the initial peak amplitude range, then sound confirmation information is obtained reflecting that the sound of the patient's throat when swallowing is abnormal.
[0099] It is understood that the sound is considered normal only when the monitored dominant frequency is within the initial dominant frequency range and the monitored peak amplitude is within the initial measured peak amplitude range. Using dual indicators for judgment can reduce the possibility of misjudgment. If the dominant frequency is normal, it means that the pitch of the airflow vibration in the throat during swallowing is stable (no high-frequency noise, no low-frequency abnormalities, and no risks of choking, obstruction, etc.). If the peak amplitude is normal, it means that the intensity of the sound is moderate (no sudden loud sound, no too weak sound, and no excessive force or weak swallowing).
[0100] S260: Confirm the pressure confirmation information and the sound confirmation information as analysis information.
[0101] As you can see, pressure confirmation information (whether oral pressure is normal) and sound confirmation information (whether throat sounds are normal) reflect the swallowing process from the perspectives of mechanical action and acoustic feedback, respectively, forming a complete assessment of swallowing status. Analyzing these two information provides a basis for subsequent steps.
[0102] S300 , obtaining control information based on the analysis information; wherein the control information is used to control the feeding device 22 .
[0103] It is understood that the control information obtained based on the analysis information can be obtained by, for example, obtaining control information to control the feeding device 22 to feed at a standard rhythm when both the pressure confirmation information and the sound confirmation information reflect normal; obtaining control information to control the feeding device 22 to extend the feeding interval by 30% when one of the pressure confirmation information and the sound confirmation information reflects normal and the other reflects abnormal; obtaining control information to control the feeding device 22 to stop feeding and transmit the information to the medical staff when both the pressure confirmation information and the sound confirmation information reflect abnormal; or obtaining control information to receive data transmitted by the doctor after transmitting the analysis information, etc., but is not limited to these. Obtaining control information based on the analysis information can improve the problem of artificial feeding, which requires medical staff or family members to continuously observe the swallowing status, which is not only time-consuming but also prone to risks due to fatigue and misjudgment, causing the patient to choke or aspirate.
[0104] In one possible implementation, see Figure 4 S300: Obtaining control information based on the analysis information, including: S310, if within the preset interval, the pressure confirmation information and the sound confirmation information both reflect normal, and no stop signal is received, then control information for controlling the feeding device 22 to feed at the standard feeding time is obtained; wherein the standard feeding time is the time after the preset interval starting from the last time the feeding device 22 fed, and the stop signal is used to control the feeding device 22 to stop feeding.
[0105] It is understood that the preset interval can be, but is not limited to, 5 seconds, 10 seconds, etc. The stop signal is a signal sent by medical personnel or the patient to instruct the feeding device 22 to stop operation. When both the pressure confirmation information and the sound confirmation information indicate normal, controlling the feeding device 22 to perform feeding can maintain a stable nutrition supply rhythm while ensuring swallowing safety.
[0106] For example, assuming that the preset interval time is 10 seconds, and the feeding device 22 last fed the baby at 10:25:10, the standard feeding time is 10:25:20.
[0107] S320, if the pressure confirmation information and / or the sound confirmation information reflect abnormality within the preset interval time, control information is obtained to control the feeding device 22 to feed after the feeding time is extended; wherein the extended feeding time is the time obtained by adding the preset extension time to the standard feeding time.
[0108] It is understood that the preset extension time can be 10s, 20s, or a value customized by the physician, but is not limited to this. The calculation logic for extending the feeding time (standard feeding time + preset extension time) not only preserves the basal rhythm and feeding continuity, providing a window for patients to adapt and recover, but also quantitatively adjusts the risk level.
[0109] For example, assuming that the standard feeding time is 10:25:20 and the preset extension time is 20 seconds, the extended feeding time is 10:25:40.
[0110] S330: When the stop signal is received, control information for controlling the feeding device 22 to stop feeding is obtained.
[0111] It is understood that the stop signal may be initiated by the patient (e.g., by pressing an emergency button, or due to sudden pain or choking and inability to swallow), or may be remotely sent by medical personnel (e.g., by manually issuing a stop command upon noticing an abnormal patient complexion). Upon receipt of the stop signal, control information is generated to control the feeding device 22 to stop feeding, thereby creating a safe window for subsequent intervention and facilitating manual evaluation and processing.
[0112] For example, when the stop signal is received and the control information for controlling the feeding device 22 to stop feeding is obtained, a prompt message can also be sent to the medical staff to remind them that the patient has an abnormality.
[0113] Corresponding to the feeding method of the temperature-controlled feeding device described in the above embodiments, the embodiment of the present application also provides a feeding system of a temperature-controlled feeding device, and each unit of the system can implement each step of the feeding method of the temperature-controlled feeding device.
