Description

Technical Field

[0001] The present application relates to the technical field of cardiovascular flow velocity detection, and more specifically, to a cardiovascular fluid flow velocity detection system. Background Art

[0002] As one of the leading causes of death worldwide, early diagnosis and continuous monitoring of cardiovascular disease are crucial for the prevention, treatment and management of the disease. Traditional cardiovascular testing methods, such as cardiovascular angiography and echocardiography, can provide relatively accurate information on the structure and function of the cardiovascular system, but these methods often rely on large professional medical equipment and require patients to go to hospitals or medical institutions for examinations. This is not only inconvenient and time-consuming, but also costly, making it difficult to achieve daily continuous monitoring. With the rapid development of wearable technology, smart bracelets have gradually emerged as a convenient wearable device in the field of health monitoring. It can collect the flow rate of cardiovascular fluids in the human body in real time, bringing new possibilities for cardiovascular health monitoring.

[0003] However, existing smart sports bracelets have obvious limitations in terms of wrist adaptation, which mainly relies on controlling the position of the positioning column connected to the wristband to match the wrist size. This adjustment method is relatively cumbersome to operate, and users often need to spend a certain amount of time and effort to adjust the bracelet to a relatively suitable state. More importantly, its tightness can only be switched between several fixed levels limited by the positioning column, and stepless adjustment cannot be achieved. This makes it difficult for the bracelet to accurately fit the wrists of different users. During the wearing process, it may be too loose and easily shake and displace, affecting the accuracy and stability of sensor data collection. Summary of the invention

[0004] In order to solve the above problems, the present application provides a cardiovascular fluid flow rate detection system.

[0005] The cardiovascular fluid flow rate detection system provided in this application adopts the following technical solution:

[0006] A cardiovascular fluid flow rate detection system comprises a wristband body, one end of the wristband body is provided with a first strap, and the end of the wristband body away from the first strap is provided with a second strap;

[0007] Two slots are provided inside the bracelet body, and a first magnetic block is provided at the opposite ends of the first strap and the second strap. The two first magnetic blocks are respectively located inside the corresponding slots, and a second magnetic block is provided inside each slot. The two second magnetic blocks are magnetically connected to the corresponding first magnetic blocks.

[0008] Through the above technical solution, the magnetic attraction and the elastic force of the elastic part work together to enable the bracelet to fit tightly to the wrist, and the arc-shaped design at the bottom of the bracelet body fits the physiological curve of the wrist, reducing local pressure and improving the comfort of long-term wearing.

[0009] Furthermore, an elastic member is provided between each first magnetic block and the second magnetic block, and the two first magnetic blocks are slidably connected to the corresponding slot bodies respectively.

[0010] Through the above technical solution, when the strap is subjected to external force, the sliding of the first magnetic block, the buffering of the elastic part and the maintenance of the position of the magnetic connection effectively prevent the bracelet from falling off or being damaged, and ensure the normal operation of the internal cardiovascular detection elements.

[0011] Furthermore, a plurality of jacks are provided at one end of the second strap, and an insertion rod is provided at one end of the first strap away from the bracelet body, and the insertion rod is plugged into the jacks.

[0012] Furthermore, an insert block is provided at one end of the second strap away from the bracelet body, and a slot is provided inside the insert block.

[0013] Furthermore, one end of the second strap is slidably connected to a sleeve, and the bottom of the bracelet body is arranged in an arc shape.

[0014] Furthermore, replaceable straps are provided at the bottom of the first strap and the second strap, and Velcro layers are provided at the bottom of the first strap and the second strap and at the top of the replaceable straps.

[0015] Furthermore, each replaceable strap is respectively connected to the first strap and the second strap via a Velcro layer.

[0016] Through the above technical solution, when the replaceable strap needs to be replaced, it is only necessary to pull the replaceable strap hard to overcome the adhesive force of the Velcro, tear it off the strap, and then stick the new replaceable strap on in the above manner.

[0017] Furthermore, the bracelet body includes a display screen and a photoelectric sensor, both of which are arranged inside the bracelet body, and the photoelectric sensor is used to detect the flow rate of cardiovascular fluid.

[0018] Through the above technical solution, non-invasive detection of cardiovascular fluid flow rate is achieved without causing trauma to the human body like traditional cardiovascular detection methods, which greatly reduces the risks and user discomfort during the detection process, enables ordinary users to easily perform cardiovascular health monitoring in daily environments, and improves user acceptance and compliance with cardiovascular health monitoring.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] (1) The magnetic attraction of the present invention cooperates with the elastic force of the elastic member, so that the bracelet can fit the wrist tightly, and the arc-shaped design of the bottom of the bracelet body fits the physiological curve of the wrist, reducing local pressure and improving the comfort of long-term wearing. When the strap is subjected to external force, the sliding of the first magnetic block, the buffering of the elastic member and the maintenance of the position by the magnetic connection effectively prevent the bracelet from falling off or being damaged, thereby ensuring the normal operation of the internal cardiovascular detection element;

[0021] (2) The present invention can accurately adapt to different wrist thicknesses and personal preferences by changing the magnetic strength between the first magnetic block and the second magnetic block and the elastic coefficient of the elastic member, meet diverse needs, and ensure that the bracelet can be worn stably and comfortably in various situations, thereby laying the foundation for accurate detection of cardiovascular fluid flow rate;

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] Reference Figure 1-Figure 5 , a cardiovascular fluid flow rate detection system, comprising a wristband body 1, a first strap 2 is provided at one end of the wristband body 1, and a second strap 3 is provided at one end of the wristband body 1 away from the first strap 2;

[0031] Two grooves are provided inside the bracelet body 1, and a first magnetic block 10 is provided at the opposite ends of the first strap 2 and the second strap 3. The two first magnetic blocks 10 are respectively located inside the corresponding grooves, and a second magnetic block 12 is provided inside each groove. The two second magnetic blocks 12 are magnetically connected to the corresponding first magnetic blocks 10 respectively, and an elastic member 11 is provided between each first magnetic block 10 and the second magnetic block 12. The two first magnetic blocks 10 are respectively slidably connected to the corresponding grooves.

[0032] When the bracelet is worn on the wrist, the first magnetic blocks 10 at both ends of the first strap 2 and the second strap 3 are respectively located in the two slots of the bracelet body 1, and are magnetically connected to the second magnetic blocks 12 in the slots. Since an elastic member 11 is provided between each first magnetic block 10 and the second magnetic block 12, in the initial state, the magnetic attraction and the elastic force of the elastic member 11 work together to keep the strap in a certain tension, and the bracelet is worn on the wrist. When the wrist moves or is acted upon by an external force, such as when the arm is bent or stretched, the strap is pulled or squeezed, the first magnetic block 10 will slide in the slot, and the elastic member 11 will be stretched or compressed accordingly, playing a buffering role, absorbing external force, and preventing the strap connection from being damaged or causing the bracelet to fall off due to sudden force. At the same time, the magnetic connection maintains the relative position relationship between the strap and the bracelet body 1 to a certain extent, and during the deformation recovery process of the elastic member 11, it can assist the strap to return to a suitable position and keep in close contact with the wrist. By adjusting the magnetic strength between the first magnetic block 10 and the second magnetic block 12 and the elastic coefficient of the elastic member 11 , the tightness of the watch strap can be changed to meet the needs of different wrist thicknesses and personal wearing comfort of users.

[0033] When it is necessary to adjust the magnetic field strength set by the first magnetic block 10 and the second magnetic block 12 inside the bracelet, a special physical button can be set on the side or surface of the bracelet body 1. These buttons are connected to the magnetic field adjustment circuit inside the bracelet. When the user presses the button, the electrical signal generated by the button will be transmitted to the microcontroller, and the microcontroller will adjust the magnetic field strength according to the preset program. For example, two buttons "+" and "-" (which are prior art and not shown in the figure) can be set to increase and decrease the magnetic field strength respectively.

[0034] Reference Figure 1-Figure 2 A plurality of jacks 5 are provided at one end of the second strap 3, an insertion rod 4 is provided at the end of the first strap 2 away from the bracelet body 1, the insertion rod 4 is plugged into the jack 5, an insertion block 13 is provided at the end of the second strap 3 away from the bracelet body 1, a slot 8 is provided inside the insertion block 13, a ring 6 is slidably connected to one end of the second strap 3, and the bottom of the bracelet body 1 is arranged in an arc shape.

[0035] When wearing the bracelet, insert the first strap 2 into the slot 8, then insert the insertion rod 4 into the corresponding socket 5 of the second strap 3, and preliminarily adjust the length of the strap by selecting different sockets 5 to adapt to different wrist thicknesses to achieve basic wearing and fixation, and then insert the sleeve at one end of the first strap 2 into the ring 6 to prevent the first strap 2 from tilting.

[0036] The arc-shaped setting at the bottom of the bracelet body 1 is to better fit the physiological curve of the wrist, so that the bracelet can naturally fit the wrist when worn, reduce local pressure points and improve wearing comfort.

[0037] Reference Figure 4 A replaceable strap 7 is provided at the bottom of the first strap 2 and the second strap 3, and a Velcro layer 9 is provided at the bottom of the first strap 2 and the second strap 3 and the top of the replaceable strap 7, and each replaceable strap 7 is respectively connected to the first strap 2 and the second strap 3 through the Velcro layer 9.

[0038] When in use, the side of the replaceable strap 7 with the Velcro is pressed against the Velcro layer 9 at the corresponding position on the bottom of the strap, and the replaceable strap 7 is tightly attached to the strap by using the principle that the hooks and barbs of the Velcro are engaged with each other. When the replaceable strap 7 needs to be replaced, it is only necessary to pull the replaceable strap 7 hard to overcome the adhesive force of the Velcro, tear it off the strap, and then stick the new replaceable strap 7 on in the above manner.

[0039] Since the replaceable strap 7 is connected to the strap body with Velcro, when the replaceable strap 7 becomes dirty or damaged, it can be easily removed and replaced separately. Compared with the integrated strap, this design greatly reduces the difficulty of cleaning and maintaining the strap as a whole, prolongs the service life of the wristband strap part, and ensures that the wristband always maintains a good appearance and hygienic condition during long-term use.

[0040] Reference Figure 1-Figure 4 The bracelet body 1 includes a display screen and a photoelectric sensor. The display screen and the optical sensor are both arranged inside the bracelet body 1. The photoelectric sensor is used to detect the flow rate of cardiovascular fluid.

[0041] The photoelectric sensor works based on photoplethysmography. The light-emitting diode in the bracelet body 1 emits light of a specific wavelength, which penetrates the skin tissue and irradiates the blood in the blood vessels. Since the beating of the heart causes the blood volume in the blood vessels to change periodically, when the blood volume increases, the absorption and scattering of light increases; when the blood volume decreases, the absorption and scattering of light decreases. The photoelectric detector in the photoelectric sensor receives the light reflected and scattered back by the blood, and converts the changes in the light signal into electrical signals. By processing and analyzing these electrical signals, a specific algorithm is used to infer the cardiovascular fluid flow rate.

[0042] The detection system realizes non-invasive detection of cardiovascular fluid flow rate, without causing trauma to the human body like traditional cardiovascular detection methods, greatly reducing the risks and user discomfort during the detection process, allowing ordinary users to easily perform cardiovascular health monitoring in daily environments, improving user acceptance and compliance with cardiovascular health monitoring, and the photoelectric sensors and display screens integrated in the bracelet body 1 allow users to monitor cardiovascular fluid flow rate anytime and anywhere.

[0043] Working principle: First, in the wearing process, the user inserts the rod 4 of the first strap 2 into the socket 5 of the second strap 3, selects the appropriate socket 5 according to the thickness of the wrist for preliminary fixation, and inserts one end of the first strap 2 into the ring 6 to prevent it from tilting, and the arc structure at the bottom of the bracelet body 1 fits the physiological curve of the wrist closely, reducing pressure and improving comfort. In addition, the bottom of the first strap 2 and the second strap 3 are connected to the replaceable strap 7 through the Velcro layer 9, which can be easily replaced according to needs.

[0044] After wearing, the photoelectric sensor inside the bracelet body 1 starts working. Its light-emitting diode emits specific light that penetrates the skin and irradiates the blood in the blood vessels. As the heart beats, the blood volume changes periodically. The photoelectric detector receives the reflected scattered light and converts it into an electrical signal. The microcontroller processes and analyzes the electrical signal according to the preset algorithm to calculate the cardiovascular fluid flow rate and transmits the data to the display screen for presentation to the user.

[0045] During the use of the wristband, the first magnetic block 10 at the end of the first strap 2 and the second strap 3 is located in the groove of the wristband body 1 and is magnetically connected to the second magnetic block 12, and the elastic member 11 between the two provides initial tension. When the wrist is subject to external force, such as bending and stretching the arm, the strap is subjected to force to make the first magnetic block 10 slide in the groove, and the elastic member 11 stretches or compresses to buffer the external force, thereby preventing the strap connection from being damaged and the wristband from falling off. The magnetic connection maintains the relative position between the strap and the wristband body 1, and assists the strap to reset and fit the wrist when the elastic member 11 recovers its deformation. If the tightness of the strap needs to be adjusted, the user can press the "+" or "-" physical button on the side or surface of the wristband body 1, and the button electrical signal is transmitted to the microcontroller. The microcontroller changes the magnetic field strength between the first magnetic block 10 and the second magnetic block 12 according to the program, so as to adjust the tightness to adapt to different wrists and personal comfort needs, ensure that the wristband is stably worn during the entire use process, and the photoelectric sensor continuously and accurately monitors the flow rate of cardiovascular fluid, providing effective protection for the user's cardiovascular health monitoring.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
