Description

Technical Field

[0001] The present invention relates to the technical field of life assistance articles, and particularly relates to a multifunctional integrated intelligent walking stick. Background Art

[0002] Due to the work reasons of their children, the safety of the elderly traveling alone, the body sensing in case of emergency, the fall warning of the elderly, and the need to prevent the elderly from getting lost have correspondingly increased. Especially for patients with diseases, the action needs to be assisted by intelligent devices.

[0003] As a tool to assist people with lack of mobility, walking sticks are common in daily life, especially in the travel scenarios of the elderly. With the popularization of intelligent wearable devices, the demand for the intelligentization of walking sticks as the main auxiliary tool for the elderly and patients with diseases is becoming more and more urgent.

[0004] The existing Chinese patent with the publication number CN115886755A provides a walking stick for elderly patients with frailty syndrome with a fall alarm function and an intelligent fall alarm system. The defect of this existing technology is that the fall alarm function is realized by a triboelectric nanogenerator, and its working principle depends on mechanical vibration or triboelectric power generation. In the case of low vibration or slow fall, the alarm may not be accurately triggered. After long-term use, the sensitivity of the triboelectric nanogenerator may decrease, resulting in false alarms or missed alarms. The accuracy and reliability of the fall alarm are insufficient, and effective safety protection may not be provided in time.

[0005] The existing Chinese patent with the publication number CN107373938A provides an intelligent walking stick and its intelligent walking stick positioning system. By integrating a GPS module, real-time positioning is realized to help users determine their positions; an acceleration sensor is used to detect whether the user has fallen and trigger an alarm when falling. Although it has positioning, fall alarm and lighting functions, it lacks a health monitoring function and cannot meet the daily health management needs of patients with chronic diseases. At the same time, it does not integrate health monitoring sensors such as heart rate, blood pressure, and blood oxygen, and cannot collect the health data of users in real time. It cannot provide real-time monitoring and warning of the health status of elderly users.

[0006] The existing Chinese patent with the publication number CN112641182A provides a life health monitoring and navigation positioning walking stick, which can monitor various physiological indicators of the user in real time, automatically monitor the posture and location of the user, facilitate timely treatment, and reduce the potential safety hazards of the user's travel. It can monitor the position, posture information, heart rate, blood oxygen, and respiration of the user in real time. When the monitored physiological indicators exceed the threshold or the user presses the button emergently, the position and physiological indicators of the user will be sent to the associated users in time. Although it has a positioning function, it fails to implement the electronic fence technology and cannot set a safe activity area to prevent the user from getting lost or entering a dangerous area. Summary of the Invention

[0015] According to some embodiments, the intelligent fall detection radar sensor is selected from the R60BFD1 fall alarm radar.

[0016] In the above embodiments, the R60BFD1 radar module uses 60G millimeter-wave radar technology to sense human movements and postures, and then realizes the function of fall monitoring.

If a physical abnormality occurs, a warning instruction can be sent through the GSM module to notify relevant personnel to implement rescue.

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Embodiment 1

[0034] This embodiment provides a multifunctional integrated intelligent crutch, which is constructed as follows:

[0035] As Figure 1 ,Figure 1 .a is a side view, Figure 1 .b is the rear view, Figure 1 .c is a top view. The outer rod sleeve 1 and the inner rod 2 form a cane body, and the base 3 is located at the bottom of the inner rod 2. The inner rod 2 is arranged inside the outer rod sleeve 1, and can be relatively movable and fixed to adjust the overall length of the cane body. The handle 5 is fixed to the cane body by screws, nested in the outer rod sleeve 1, and located at the top. The lighting lamp 4 is installed at the front end of the handle 5. Figure 2 It is a side view of the stick body. The water cup support frame 6 is in the shape of a cup sleeve and is fixed on the outer rod sleeve 1. The storage box 7 is located at the rear end of the handle 5 and is in a drawer-type structure.

[0036] like Figure 4 The multifunctional integrated intelligent crutch includes an intelligent system, which includes a single chip microcomputer 12 embedded in the handle 5, a power supply circuit 10, a GSM module 11 and an LED circuit 13. Figure 3 It is a top view of the cane body. The human-machine interactive control panel 8 is nested in the handle 5 as a whole, and there is a button 9 on it for human-machine interactive operation. The power circuit 10 supplies power to the entire intelligent system. The GSM module 11 and the LED circuit 13 are electrically connected to the single-chip computer 12 respectively. The single-chip computer 11 is also connected to the Bluetooth module 14, the GPS module 15, the vital signs monitoring module 16, the collision detection module 17 and the voice circuit 18. The single-chip computer 11 controls the coordinated work of each module. Among them, the GSM module 11 is used for communication; the LED circuit 13 is electrically connected to the lighting lamp 4 to control the lighting of the lighting lamp 4; the Bluetooth module 14 is used to transmit the real-time collected health data of the vital signs monitoring module 16 to the human-machine interactive control panel 8; the GPS module 15 is used to collect positioning information and transmit it to the single-chip computer 11; the voice circuit 18 is used to receive the control information sent by the single-chip computer 12 and play a sound alarm; the vital signs monitoring module 16 is used to detect vital signs, and the collision detection module 17 is used to detect falls.

[0037] The vital sign monitoring module 16 is placed at the handle of the crutch, and the sensing chip is in contact with the palm. The sensing chip has a built-in body temperature measurement sensor, a dynamic blood oxygen monitoring sensor (for real-time monitoring of blood oxygen values), and an optical heart rate sensor (for continuous heart rate monitoring); the vital sign monitoring module 16 monitors the user's heart and body characteristics in real time.

[0038] During use, when the user holds it, their fingers naturally touch the sensor area of the vital sign monitoring module 16. The body temperature measurement sensor is selected from an infrared temperature sensor or a thermocouple sensor. The infrared temperature sensor calculates the body temperature by detecting the infrared radiation on the user's skin surface, and the thermocouple sensor directly obtains the body temperature data through contact measurement; the red light LED and the infrared LED emit light of different wavelengths, which penetrate the skin and are received by the photodetector. By analyzing the absorption difference of the two wavelengths of light, the blood oxygen saturation (SpO2) is calculated; the infrared LED emits light that penetrates the skin, and the photodetector receives the reflected light signal. By analyzing the change of the reflected light signal, the minute light intensity change caused by blood flow is detected, thereby calculating the heart rate; the data information is transmitted to the single-chip microcomputer 12. When abnormalities such as blood oxygen index, heart rate, and blood pressure occur, the voice circuit 18 automatically emits a warning sound. At the same time, the single-chip microcomputer 12 transmits the alarm signal to the server for data storage and analysis through the GSM module 11 or the Bluetooth module 14, or to the mobile terminal for analysis and display. The mobile terminal is devices such as mobile phones and smart bracelets, which display the body condition data. Among them, the body temperature measurement sensor, the dynamic blood oxygen monitoring sensor, and the optical heart rate sensor are all existing products.

[0039] The collision detection module 17 is used to monitor the user's falling situation and automatically send a distress signal to others. The collision detection module 17 is built-in with the R60BFD1 fall alarm radar and a three-axis acceleration sensor. Among them, the R60BFD1 fall alarm radar conducts real-time warning of the crutch falling to the ground by judging the posture of the crutch body, and at the same time links the human body fall warning; the three-axis acceleration sensor mainly detects abnormal acceleration changes. For example, if the user's gravity direction suddenly changes, it may indicate that the user has fallen. The three-axis acceleration sensor detects the acceleration changes of the crutch in the X, Y, and Z directions in real time. When the user has a collision or falls, the acceleration of the crutch will suddenly change, and the sensor captures this change and generates a corresponding signal. The data is transmitted to the single-chip microcomputer through the I2C or SPI interface. The R60BFD1 fall alarm radar and the three-axis acceleration sensor send the alarm signal to the single-chip microcomputer 12, and the single-chip microcomputer 12 immediately triggers the alarm mechanism and emits a sound warning through the voice circuit 18, so as to ensure that the fallen person can get help quickly. The fall alarm radar (see the Chinese patent with the publication number CN118177787A) and the three-axis acceleration sensor (see the Chinese patent with the publication number CN113156164A) are both existing technologies and will not be elaborated here.

[0040] This intelligent walking stick, by equipping a collision detection module 17, a vital sign monitoring module 16, an LED circuit 13 and a GPS module 11 on the basis of the stick body, and simultaneously having functions of height adjustment, sound generation and emergency communication, makes the walking stick intelligent and multifunctional. The collision detection module 17 is mainly used to detect and diagnose whether the user has fallen or other situations, and transmits a rescue signal in time through the GSM module 15. The vital sign monitoring module 16 timely detects parameters such as the user's blood oxygen, heart rate and body temperature. The LED circuit 13 facilitates travel in low-illumination environments. The real-time positioning module of the GPS module 15 is used to monitor the user's activity range. The height adjustment function improves the comfort of using the walking stick and expands the user group. The sound generation function of the voice circuit 18 plays an effect of prompting to avoid.

[0041] Such as Figure 3 It is an embodiment of the working process of the collision detection module, the vital sign monitoring module and the GPS module in the intelligent walking stick. This flow chart shows the main functional modules of the intelligent walking stick and their working processes, covering functions such as health monitoring, fall detection, geofencing, navigation and positioning, and emergency assistance.

[0042] Such as Figure 4 It is a schematic illustration of the overall working process of the intelligent walking stick.

[0043] The above embodiments are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
