Technical Field

[0002] Hypertension is a systemic disease characterized primarily by elevated blood pressure. The "Report on Nutrition and Chronic Diseases of Chinese Residents (2020)" shows that the prevalence of hypertension among Chinese residents aged 18 and above is 27.5%, with prevalence rates of 13.3% for those aged 18-44, 37.8% for those aged 45-59, and 59.2% for those aged 60 and above. The overall prevalence of hypertension in my country is on the rise, with an estimated 245 million adults currently suffering from the condition. Hypertension is a leading cause of cardiovascular diseases such as coronary heart disease and stroke, as well as death. Therefore, hypertension is a significant public health issue facing my country today.

[0003] Many risk factors for hypertension are related to an unhealthy diet, including high-sodium, low-potassium diets, and excessive alcohol consumption. Overweight and obesity, which are closely related to diet, are also important risk factors for hypertension. Dietary intervention is a recognized measure for the prevention and treatment of hypertension both domestically and internationally, and it is extremely important for improving blood pressure. Selecting foods or medicinal substances with different properties based on the individual constitution of hypertensive patients can improve their blood pressure levels.

[0047] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0048] The following is for reference. Figure 1 and Figures 4-8 This application describes a refrigeration device according to an embodiment of the present application.

[0049] The refrigeration equipment in this application embodiment can be understood as a broad refrigeration storage device, including but not limited to freezers, refrigerators, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines, etc. Refrigeration equipment has diverse structural forms and a wide range of applications.

[0050] In this embodiment of the application, the refrigeration equipment includes a cabinet and a cabinet door, and the surface of the cabinet door may be made of a layer of glass.

[0051] like Figure 1 As shown in the embodiment of this application, the refrigeration device includes a blood pressure detection module 110 and a human-computer interaction module 120.

[0052] The blood pressure detection module 110 can be used to detect the user's blood pressure, and the human-computer interaction module 120 can realize interaction with the user, including voice interaction, gesture interaction, click and touch, etc.

[0053] The blood pressure detection module 110 can be installed on the outer surface of the refrigeration equipment, or in a position that is easily accessible to the user on the cabinet door of the refrigeration equipment. For example, the blood pressure detection module 110 can be installed 1.5 meters above the ground of the refrigeration equipment.

[0054] Users can place their fingers on the blood pressure detection module 110 and apply appropriate pressure to detect blood pressure.

[0055] In this embodiment, the blood pressure detection module 110 and the human-machine interaction module 120 are connected. The cooling device can send the detected blood pressure to the human-machine interaction module 120. The human-machine interaction module 120 can send user input or generated control signals to the blood pressure detection module 110.

[0056] In this embodiment, the human-computer interaction module 120 may include a touch screen installed on the cabinet door of the refrigeration equipment, a client application, a camera installed on the cabinet door of the refrigeration equipment, an infrared / ultrasonic detector installed on the cabinet door of the refrigeration equipment, and a voice module installed on the cabinet door of the refrigeration equipment.

[0057] When the human-machine interaction module 120 includes a touch screen installed on the door of the refrigeration equipment, the user can perform input operations through the touch screen, such as clicking buttons, entering text or voice.

[0058] When the human-computer interaction module 120 includes a client application, the user can perform input operations through the mobile application, such as entering relevant information or clicking buttons on the application interface.

[0059] When the human-computer interaction module 120 includes a camera installed on the cabinet door of the refrigeration equipment, it can capture the user's face or hand image through the camera, perform face recognition or gesture recognition on the user, and obtain the user's input actions.

[0060] Cameras can be wide-angle cameras, infrared cameras, high-definition cameras, panoramic cameras, wireless cameras, night vision cameras, smart cameras, etc.

[0061] When the human-computer interaction module 120 includes an infrared / ultrasonic detector installed on the cabinet door of the refrigeration equipment, the user can detect the user's near-field movements or gestures through infrared or ultrasonic waves to obtain the user's input actions.

[0062] When the human-computer interaction module 120 includes a voice module installed on the cabinet door of the refrigeration equipment, the voice module includes components such as a microphone, amplifier and signal processing circuit. The user can make voice input through the microphone, and the voice module performs voice recognition after receiving the user's voice input.

[0063] In the above technical solution, different forms of human-computer interaction modules 120 provide a variety of user interaction methods, allowing users to choose the most suitable input method and ensuring the accuracy and reliability of data collection. This can better adapt to the needs and habits of different users, provide more convenient, intelligent and humanized services, and improve the user experience.

[0064] In this embodiment, the blood pressure detection module 110 or the human-computer interaction module 120 is used to receive the user's first input.

[0065] The first input is an input that can trigger the blood pressure detection module 110 to perform blood pressure detection.

[0066] Users can trigger blood pressure detection through the blood pressure detection module 110 or through interactive behavior through the human-computer interaction module 120.

[0067] For example, a user can press the blood pressure detection module 110 with appropriate force, and the blood pressure detection module 110 will sense the pressure and perform blood pressure detection.

[0068] For example, a user can input specific voice information into the human-computer interaction module 120. The voice information could be: "I want to measure my blood pressure." The user can then place their finger on the blood pressure detection module 110 and press the blood pressure detection module 110 with appropriate force. Upon receiving the user's voice input, the human-computer interaction module 120 can generate a blood pressure detection control signal and output the control signal to the blood pressure detection module 110 to control the blood pressure detection module 110 to perform blood pressure monitoring.

[0069] In this embodiment, the blood pressure detection module 110 is used to determine whether the pressure applied by the user to the blood pressure detection module 110 is within the target pressure range.

[0070] The target pressure range is the contact pressure range within which the blood pressure detection module 110 can monitor blood pressure when the user touches it.

[0071] In this embodiment, the blood pressure detection module 110 can acquire the pressure of the user touching the blood pressure detection module 110, compare the acquired pressure with two boundary values ​​of the target pressure range, and thus determine whether the pressure of the user touching the blood pressure detection module 110 is within the target pressure range.

[0072] It is understandable that the blood pressure detection module 110 can determine that the pressure of the user contacting the blood pressure detection module 110 is within the target pressure range when the pressure is greater than or equal to one boundary value of the target pressure range and less than or equal to another boundary value of the target pressure range.

[0073] In this embodiment, if the pressure applied by the user to the blood pressure detection module 110 is not within the target pressure range, the human-computer interaction module 120 is used to output a prompt message to the user.

[0074] If the pressure applied by the user to the blood pressure detection module 110 is not within the target pressure range, it could be due to insufficient pressure causing light leakage, or excessive pressure causing blood vessel deformation.

[0075] When the pressure applied to the blood pressure detection module 110 by the user is outside the target pressure range, the blood pressure information collection process may be interfered with, resulting in inaccurate blood pressure detection results.

[0076] In this embodiment, the prompt message output to the user can be: if the pressure of the user touching the blood pressure detection module 110 is too low, the user can be prompted to press their finger harder and increase the contact pressure; or if the pressure of the user touching the blood pressure detection module 110 is too high, the user can be prompted to press their finger harder and decrease the contact pressure, so that the user can readjust the pressure until the pressure is within the target pressure range.

[0077] The methods for providing prompts to users include voice prompts, on-screen prompts, and can also be combined with light-emitting devices, the brightness of which changes with the magnitude of the contact pressure.

[0078] In this embodiment, when the pressure applied by the user to the blood pressure detection module 110 is within the target pressure range, the blood pressure detection module 110 is used to collect the user's current blood pressure information in response to the first input.

[0079] The current blood pressure information refers to the blood pressure readings taken during this user's blood pressure test.

[0080] In this embodiment, when the user makes a first input and the pressure of the blood pressure detection module 110 is within the target pressure range, the blood pressure detection module 110 can detect blood pressure based on the body part of the user that is in contact with the blood pressure detection module 110. For example, the blood pressure detection module 110 can detect blood pressure based on the transmitted or reflected light beam from the body part of the user that is in contact with the blood pressure detection module 110.

[0081] In this embodiment, the human-computer interaction module 120 is used to output current blood pressure information and simultaneously output target dietary information to the user.

[0082] The target dietary information refers to the guidance and suggestions on food and nutrient intake recommended by the cooling device based on the user's current blood pressure information. The target dietary information may also include recipes.

[0083] In practice, the refrigeration equipment can generate a recipe from the target diet information based on the remaining food in the refrigeration equipment and the user's current blood pressure information. When the amount of remaining food in the refrigeration equipment is insufficient or there is a lack of food that suits the user, the equipment can recommend that the user purchase the corresponding food.

[0084] For example, the target diet information could recommend eating at least five different types of fresh vegetables and fruits every day, limiting daily salt intake to less than 6 grams, consuming adequate amounts of high-quality protein such as fish, poultry, eggs, dairy products, and soy products, while reducing the intake of red meat and high-fat dairy products, using cooking methods such as steaming, boiling, baking, and stewing, and providing a recipe for stir-fried black fungus with eggs with detailed cooking steps, as well as recommending the purchase of celery and milk.

[0085] In this embodiment, the human-computer interaction module 120 can display the target diet information and current blood pressure information on the display screen, or output the target diet information and current blood pressure information through voice broadcast, or output the target diet information and current blood pressure information to the user's mobile phone or other terminal devices. The human-computer interaction module 120 can also output the target diet information and current blood pressure information to the user through any other interaction method.

[0086] In related technologies, blood pressure measurement devices are all independent devices that can only provide blood pressure information and cannot perform further interactions based on that information.

[0087] In this embodiment, a blood pressure detection module 110 and a human-machine interaction module 120 are provided on the refrigeration equipment. Both the blood pressure detection module 110 and the human-machine interaction module 120 can receive the user's first input. When the user's first input is received, the blood pressure detection module 110 can collect the user's current blood pressure information. After obtaining the user's current blood pressure information, the refrigeration equipment can generate corresponding target dietary information based on the current blood pressure information, and output the target dietary information and current blood pressure information to the user through the human-machine interaction module 120. The blood pressure detection module 110 is set on the refrigeration equipment, and the refrigeration equipment can interact with the user to realize the combination of blood pressure detection and food management.

[0088] According to the refrigeration device provided in the embodiments of this application, by setting a blood pressure detection module 110 and a human-computer interaction module 120, when the blood pressure detection module 110 or the human-computer interaction module 120 receives the user's first input trigger, the blood pressure detection module 110 can collect the user's current blood pressure information, the refrigeration device can generate corresponding current blood pressure information and target dietary information based on the current blood pressure information, and the human-computer interaction module 120 outputs the target dietary information to the user. The refrigeration device can interact with the user, realizing the combination of blood pressure detection and food management.

[0089] In some embodiments, the first input received by the human-computer interaction module 120 includes voice input or trigger switch input.

[0090] In this embodiment, the human-computer interaction module 120 may include a voice receiving device, and the user can give voice input to the voice receiving device, for example, the user can say to the voice receiving device: I want to measure my blood pressure.

[0091] In this embodiment, the human-computer interaction module 120 may include an interactive interface, which the user can touch to select or input blood pressure monitoring requirements.

[0092] Understandably, users can also input signals to the human-computer interaction module 120 through interactive buttons, gesture recognition, and other means.

[0093] In this embodiment, the human-computer interaction module 120 may include an interactive switch, which may be a physical switch or a virtual switch displayed on the interactive interface. The user can trigger the switch input, that is, turn on the interactive switch to realize the first input.

[0094] Understandably, once the interactive switch is turned on, the blood pressure detection module 110 can be used to measure the user's blood pressure.

[0095] In this embodiment, the first input can be an input signal from a user on a terminal device, which is used to output the input signal to the cooling device.

[0096] In this embodiment, the terminal device can be a mobile phone, smart bracelet, desktop computer, laptop computer, etc. The terminal device communicates with the cooling device and can communicate via a Universal Asynchronous Receiver / Transmitter (UART).

[0097] Users select or input their blood pressure monitoring needs on the terminal device, and the terminal device outputs the corresponding input signal to the cooling device.

[0098] In some embodiments, the first input received by the blood pressure detection module 110 includes the pressure input from the user touching the blood pressure detection module 110.

[0099] The pressure input represents the pressure exerted by the user on the blood pressure detection module 110.

[0100] In this embodiment, when the pressure applied by the user to the blood pressure detection module 110 is within the target pressure range, the blood pressure detection module 110 can be triggered to monitor the user's blood pressure; when the pressure applied by the user to the blood pressure detection module 110 is outside the target pressure range, the blood pressure detection module 110 can be triggered to stop monitoring the user's blood pressure.

[0101] In this embodiment, the blood pressure detection module 110 can also be triggered to monitor the user's blood pressure if the duration of the user's contact with the blood pressure detection module 110 exceeds the target duration.

[0102] In some embodiments, the blood pressure detection module 110 is used to acquire the user's photoplethysmography (PPG) signal, which is used to determine the current blood pressure information.

[0103] In this embodiment, the user can touch the blood pressure detection module 110 with their finger, and the blood pressure detection module 110 can obtain the user's blood pressure based on the light beam passing through the blood vessels of the finger.

[0104] When a user's heart beats, blood flows, causing changes in blood flow to the blood vessels in the finger's skin. This results in changes in the amount of light absorbed. The blood pressure detection module 110 can measure these changes in light absorption and convert them into a photoplethysmography (PPG) signal to obtain the blood pressure.

[0105] Understandably, if the pressure of the finger touching the blood pressure detection module 110 is too low, light may leak between the finger and the blood pressure detection module 110, affecting the detection results; if the pressure of the finger touching the blood pressure detection module 110 is too high, the blood vessels may deform, which will also affect the detection results.

[0106] The pressure applied by the finger to the blood pressure detection module 110 is within the target pressure range to ensure no light leakage between the finger and the blood pressure detection module 110, and that the blood vessels do not deform.

[0107] In this embodiment, the photoplethysmo graph (PPG) signal is used to determine the current blood pressure information, which can be represented as a curve that changes over time.

[0108] In this embodiment, features of the photoplethysmography (PPG) signal, such as peaks, troughs, and frequencies, can be extracted using methods such as machine learning and deep learning to determine the current blood pressure information.

[0109] In related technologies, blood pressure measurement devices are usually invasive or cuff-type. Invasive blood pressure monitoring devices can cause trauma to users, while cuff-type blood pressure monitoring devices have a cumbersome measurement process.

[0110] In this embodiment, the user's current blood pressure information is obtained through the photoplethysmography (PPG) signal corresponding to the user. The blood pressure measurement process is simple and does not cause trauma to the user.

[0111] In some embodiments, the blood pressure detection module 110 includes a beam emitting device 111 and a beam receiving device 112. The beam emitting device 111 is used to emit a detection beam to a target site of the user, and the beam receiving device 112 is used to receive the detection beam returned from the target site of the user. The photoplethysmography signal is determined based on the detection beam signal emitted by the beam emitting device 111 and the detection beam signal received by the beam receiving device 112.

[0112] The detection beam emitted by the beam emitting device 111 is the source of the beam received by the beam receiving device 112. After passing through arteries and veins at the user's target location, the detection beam returns to the beam receiving device 112.

[0113] Among them, the beam emitting device 111 is a device that can emit light, which can be a light-emitting diode (LED), and the beam receiving device 112 is a device that can receive light, which can be a photodiode (PD).

[0114] In this embodiment, the beam emitting device 111 can emit a detection beam toward a target part of the user, which may be a finger.

[0115] After the detection beam reaches the finger, it can return through the blood vessels of the finger. The return can take the form of transmission or reflection. The detection beam returning through the blood vessels of the finger can be received by the beam receiving device 112.

[0116] When a user's heart beats, the blood flow changes with the heartbeat, causing changes in blood flow to the surface of the finger skin, which in turn affects the amount of light reflected from the finger surface, and also affects the amount of light transmitted to the finger surface.

[0117] In this embodiment, the detection beam signal emitted by the beam emitting device 111 can be compared with the detection beam signal received by the beam receiving device 112, and the comparison result can be converted to obtain a photoplethysmography (PPG) signal.

[0118] Before comparison, the detection beam signal emitted by the beam emitting device 111 and the detection beam signal received by the beam receiving device 112 can be preprocessed by DC signal removal, high-frequency noise reduction and signal clipping.

[0119] In this embodiment, the blood pressure detection module 110 can be provided with a light-transmitting hole. The user places his finger on the hole to monitor blood pressure. The finger completely covers the hole to prevent light from passing through. The hole can be covered by a transparent glass that transmits light evenly to prevent the beam emitting device 111 and the beam receiving device 112 from being worn.

[0120] In this embodiment, such as Figure 3 As shown, the blood pressure detection module 110 can obtain the photoplethysmography (PPG) signal through the following steps.

[0121] Step 310: The beam emitting device 111 emits a detection beam to the user's target area.

[0122] Step 320: The beam receiving device 112 receives the detection beam returned from the user's target location.

[0123] Step 330: The blood pressure detection module 110 determines the photoplethysmography (PPG) signal based on the detection beam signal emitted by the beam emitting device 111 and the detection beam signal received by the beam receiving device 112.

[0124] In some embodiments, such as Figure 4 As shown, the beam emitting device 111 and the beam receiving device 112 are located on the side of the blood pressure detection module 110 near the target area. The beam receiving device 112 is used to receive the detection beam reflected from the target area.

[0125] In this embodiment, such as Figure 5 As shown, the beam emitting device 111 and the beam receiving device 112 can be symmetrically distributed. A light shield 114 can be set between the beam emitting device 111 and the beam receiving device 112. The light shield 114 is in close contact with the inner wall of the cabinet door glass of the refrigeration equipment, that is, in close contact with the inner wall of the small hole corresponding to the blood pressure detection module 110, in order to prevent light leakage.

[0126] like Figure 4 As shown, the blood pressure detection module 110 includes two beam emitting devices 111, which are located on both sides of the beam receiving device 112. The beam receiving device 112 receives the detection beam emitted by the two beam emitting devices 111 and reflected by the blood vessels of the finger.

[0127] The two beam emitting devices 111 can be an infrared light emitting diode (IRLED) and a red light emitting diode, respectively.

[0128] In some embodiments, such as Figure 6 As shown, the beam emitting device 111 and the beam receiving device 112 are respectively located on opposite sides of the target part, and the beam receiving device 112 is used to receive the detection beam transmitted by the target part.

[0129] In this embodiment, such as Figure 7 As shown, the beam emitting device 111 can be set inside the glass of the cabinet door of the refrigeration equipment, that is, inside the small hole corresponding to the blood pressure detection module 110. A finger-shaped light-shielding shell is set outside the small hole, and the beam receiving device 112 is set on the inner surface of the light-shielding shell. The light-shielding shell and the cabinet door of the refrigeration equipment can be connected by a hinge with spring damping.

[0130] like Figure 6 As shown, the blood pressure detection module 110 includes two beam emitting devices 111, each beam emitting device 111 corresponding to a beam receiving device 112. The beam receiving device 112 receives the detection beam emitted by the corresponding beam emitting device 111 and transmitted through the blood vessels of the finger.

[0131] The two beam emitting devices 111 can be an infrared light emitting diode (IRLED) and a red light emitting diode, respectively.

[0132] In this embodiment, the blood pressure detection module 110 uses a transmission or reflection method to collect the photoplethysmography (PPG) signal of the user's finger to obtain the user's blood pressure. This is a non-invasive method that can avoid interference from the external environment. The transmission or reflection method can accurately capture the blood flow signal and can collect a stable PPG signal under different environmental conditions.

[0133] In some embodiments, the blood pressure detection module 110 includes a pressure sensor 113 for detecting the pressure exerted by the user when touching the blood pressure detection module 110.

[0134] like Figure 8As shown, the pressure sensor 113 can be a ring structure. The ring-shaped pressure sensor 113 can be set on the periphery of the blood pressure detection module 110. On the surface of the cabinet door of the refrigeration equipment, the wires of the pressure sensor 113 can be hidden in the glass of the refrigeration equipment cabinet door by printing.

[0135] like Figure 8 As shown, an indicator light 115 can also be set around the pressure sensor 113. The brightness of the indicator light 115 can increase as the pressure input signal value collected by the pressure sensor 113 increases.

[0136] In this embodiment, when a user's finger touches the blood pressure detection module 110, the pressure sensor 113 can detect the pressure exerted by the user's finger on the blood pressure detection module 110. In some embodiments, the blood pressure detection module 110 is used to determine the pressure exerted by the user's finger on the blood pressure detection module 110 through a pressure waveform.

[0137] The pressure waveform is used to determine the pressure of the user contacting the blood pressure detection module 110, and can be represented as a curve that changes over time.

[0138] In actual operation, the pressure waveform can be determined based on the detection beam signal emitted by the beam emitting device 111 and the detection beam signal received by the beam receiving device 112.

[0139] In this embodiment, the blood pressure detection module 110 may include a control system, and the control system of the blood pressure detection module 110 can obtain the pressure of the user contacting the blood pressure detection module 110 based on the pressure waveform.

[0140] The blood pressure detection module 110 can also upload the pressure waveform to the control system corresponding to the refrigeration equipment. The control system corresponding to the refrigeration equipment can obtain the pressure of the user contacting the blood pressure detection module 110 based on the pressure waveform.

[0141] In this embodiment, features of the pressure waveform, such as peaks, troughs, and frequencies, can be extracted using methods such as machine learning and deep learning to determine the pressure of the user contacting the blood pressure detection module 110.

[0142] In some embodiments, the human-computer interaction module 120 is used to send target dietary information to the user's terminal device.

[0143] In this embodiment, the terminal device is communicatively connected to the refrigeration equipment, and the human-machine interaction module 120 can send the target diet information to the user's terminal device via SMS or WeChat.

[0144] In some embodiments, the human-computer interaction module 120 further includes a human-computer interaction interface, which is used to display target dietary information.

[0145] In this embodiment, the display document corresponding to the target dietary information can be scaled and scrolled on the human-computer interaction interface.

[0150] Step 210: Receive the user's first input.

[0151] Step 220: Determine whether the pressure applied by the user to the blood pressure detection module 110 is within the target pressure range.

[0152] Step 230: If the pressure applied by the user to the blood pressure detection module 110 is not within the target pressure range, control the human-machine interaction module 120 to output a prompt message to the user;

[0153] Alternatively, if the pressure applied by the user to the blood pressure detection module 110 is within the target pressure range, the blood pressure detection module 110 is controlled to respond to the first input and collect the user's current blood pressure information.

[0154] Step 240: Control the human-computer interaction module 120 to output the current blood pressure information, and at the same time output the target diet information to the user.

[0155] Users can adjust their eating habits based on the target dietary information they receive, and use the food in the refrigeration equipment to cook suitable dishes, enabling convenient and reasonable dietary management.

[0156] According to the interaction method of the refrigeration equipment provided in the embodiments of this application, by setting up a blood pressure detection module 110 and a human-computer interaction module 120, when the blood pressure detection module 110 or the human-computer interaction module 120 receives the user's first input trigger, the blood pressure detection module 110 can collect the user's current blood pressure information, the refrigeration equipment can generate corresponding current blood pressure information and target dietary information based on the current blood pressure information, and the human-computer interaction module 120 outputs the target dietary information to the user. The refrigeration equipment can interact with the user to realize the combination of blood pressure detection and food management.

[0157] In some embodiments, the blood pressure detection module is controlled to respond to a first input and collect the user's current blood pressure information, including:

[0158] The blood pressure detection module responds to the first input and acquires the user's photoplethysmography (PPG) signal.
