It is suitable for long-term health monitoring scenarios.

Description

Technical Field

[0001] This utility model relates to the field of cardiovascular monitoring technology, specifically a cardiovascular monitoring watchband. Background Technology

[0002] Cardiovascular and cerebrovascular diseases are a general term for diseases of the heart and brain blood vessels. They refer to ischemic or hemorrhagic diseases of the heart, brain and other tissues caused by hyperlipidemia, blood viscosity, arteriosclerosis and hypertension. They often occur in middle-aged and elderly people. In order to better prevent and treat them, it is usually necessary to pay close attention to the patient's electrocardiographic activity. Therefore, wearing a watch for electrocardiographic monitoring at all times is one of the best measures to protect the patient.

[0003] Current technologies typically monitor the cardiovascular system in real time by monitoring the pulse. However, many current monitoring devices, when worn on the wrist, often cannot fit snugly against the wrist, preventing the sensor from monitoring the pulse and thus affecting the real-time monitoring effect. If the strap is tightened, it will constrict the user's wrist for a long time, causing discomfort. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cardiovascular monitoring watchband to solve the technical problem that the monitoring device cannot fit snugly against the wrist after being worn, thus affecting real-time monitoring, while locking the watchband will cause discomfort to the user for a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cardiovascular monitoring watchband, comprising a monitoring body, an insertion port fixedly connected to one side of the monitoring body, a watchband fixedly connected to one side of the monitoring body, a rotating shaft rotatably connected inside the monitoring body, a gear fixedly connected to the outside of the rotating shaft, an airbag fixedly connected inside the monitoring body, a first air chamber opened inside the airbag and located inside the monitoring body, and a second air chamber opened at the bottom of the airbag and located outside the monitoring body.

[0006] By adopting the above technical solution, this utility model uses a strap made of elastic rubber. One end is fixed inside the monitoring device, and the other end has a toothed structure that meshes with an internal gear through an insertion port. When wearing the watch, the strap is wrapped around the wrist and inserted into the insertion port. Turning the knob drives the gear to rotate, which in turn tightens the strap to achieve initial fixation. During the tightening process, the pressure change of the air chamber is triggered by squeezing the air bladder. After the first air chamber is compressed, the gas is transferred to the second air chamber, causing the external air bladder to expand and fit tightly against the skin of the wrist, ensuring that there is no gap between the monitoring module and the pulse contact surface. The air bladder is designed with elastic material, and after inflation, it only generates moderate pressure to avoid excessive compression, while maintaining a stable fit. This structure, through the combination of mechanical locking and adaptive air pressure adjustment, solves the technical problem of traditional devices causing discomfort due to excessive tightness or affecting monitoring accuracy due to excessive looseness, and is suitable for long-term health monitoring scenarios.

[0007] Furthermore, the second air chamber is located at the bottom of the first air chamber, and the second air chamber is connected to the first air chamber.

[0008] By adopting the above technical solution, one end of the watchband will gradually move into the monitoring body under the rotation of the gears. At this time, the airbag will be squeezed. When the airbag is squeezed, the first air chamber will be squeezed, and the gas in it will move into the second air chamber, thereby expanding the airbag located outside the monitoring body. This will make the bottom of the airbag fit tightly against the user's wrist, further locking the user's wrist. This ensures that the sensor inside the watchband can fit tightly against the user's pulse, avoiding gaps that could affect real-time monitoring.

[0009] Furthermore, a fixing head is fixedly connected to one end of the watch strap, and the watch strap is fixedly connected to the monitoring body through the fixing head. One end of the watch strap is provided with teeth, and the teeth of the watch strap mesh with gears. A knob is fixedly connected to one end of the rotating shaft, and the knob is located outside the monitoring body.

[0010] By adopting the above technical solution, when the user wears the device, he can place the monitoring body on his wrist, then wrap the watch strap around his wrist and insert it into the monitoring body through the insertion port. At this time, turning the knob will drive the rotating shaft to rotate, which in turn drives the gear to rotate. The gear meshes with the teeth on the watch strap, thus securing the user's wrist and fixing the monitoring body to the user's wrist.

[0011] Furthermore, a sensor is fixedly connected to the inside of the watch strap, and a display screen is fixedly connected to the top of the monitoring device. The sensor and the display screen are electrically connected.

[0012] By adopting the above technical solution, the sensor records the user's pulse in real time after it is attached to the device. The sensor cable is located inside the watch strap, passes through the watch strap to the inside of the monitoring device, and is electrically connected to the display screen, so that the display screen can display the data in real time.

[0013] In summary, this utility model has the following beneficial effects: The watch strap is made of elastic rubber, with one end fixed inside the monitoring device and the other end having a toothed structure that meshes with internal gears through an insertion port. When worn, the strap is wrapped around the wrist and inserted into the insertion port. Turning the knob drives the gear to rotate, tightening the strap for initial fixation. During the tightening process, the pressure change in the air chamber is triggered by squeezing the air bladder. After the first air chamber is compressed, the gas is transferred to the second air chamber, causing the external air bladder to expand and fit snugly against the wrist skin, ensuring no gap between the monitoring module and the pulse contact surface. The air bladder is designed with elastic material, generating only moderate pressure after inflation to avoid excessive compression while maintaining a stable fit. This structure, through a combination of mechanical locking and adaptive air pressure adjustment, solves the technical problem of traditional devices causing discomfort due to excessive tightness or affecting monitoring accuracy due to excessive looseness, making it suitable for long-term health monitoring scenarios.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] A cardiovascular monitoring watchband, such as Figure 1-4 As shown, it includes a monitoring body 1, an insertion port 2 is fixedly connected to one side of the monitoring body 1, and a watch strap 3 is fixedly connected to one side of the monitoring body 1, wherein the watch strap 3 itself is made of elastic rubber material;

[0022] Furthermore, a rotating shaft 4 is rotatably connected inside the monitoring body 1, and a gear 5 is fixedly connected to the outside of the rotating shaft 4. One end of the watch strap 3 is designed with multiple sets of teeth and can be inserted into the monitoring body 1 through the insertion port 2. A gear 5 is installed at the connection between the monitoring body 1 and the insertion port 2, and the teeth on the watch strap 3 and the teeth of the gear 5 can mesh with each other.

[0023] Furthermore, an airbag 6 is fixedly connected inside the monitoring body 1. A first air chamber 8 is opened inside the airbag 6 and is located inside the monitoring body 1. A second air chamber 9 is opened at the bottom of the airbag 6 and is located outside the monitoring body 1. The second air chamber 9 is located at the bottom of the first air chamber 8 and is connected to the first air chamber 8.

[0024] One end of the watch strap 3 will gradually move into the monitoring body 1 under the rotation of the gear 5. This will compress the airbag 6. When the airbag 6 is compressed, the first air chamber 8 will also be compressed, and the gas in it will move into the second air chamber 9. This will expand the airbag 6 located outside the monitoring body 1, so that the bottom of the airbag 6 is in close contact with the user's wrist, further locking the user's wrist. This will ensure that the sensor 10 inside the watch strap 3 is in close contact with the user's pulse, avoiding gaps that could affect real-time monitoring.

[0025] In the example, a fixing head 7 is fixedly connected to one end of the watch strap 3. The watch strap 3 is fixedly connected to the monitoring body 1 through the fixing head 7. One end of the watch strap 3 is provided with teeth, which mesh with the gear 5. A knob 11 is fixedly connected to one end of the rotating shaft 4, and the knob 11 is located outside the monitoring body 1. When the user wears the watch, the monitoring body 1 can be placed on the wrist, and then the watch strap 3 can be wrapped around the wrist and inserted into the monitoring body 1 through the insertion port 2. At this time, the knob 11 is rotated, which drives the rotating shaft 4 to rotate, thereby driving the gear 5 to rotate. The gear 5 meshes with the teeth on the watch strap 3, so the user's wrist can be fastened and the monitoring body 1 can be fixed on the user's wrist.

[0026] In the example, a sensor 10 is fixedly connected to the inside of the watch strap 3, and a display screen 12 is fixedly connected to the top of the monitoring body 1. The sensor 10 is electrically connected to the display screen 12. The sensor 10 records the user's pulse in real time after it is placed against the watch strap 3. The cable of the sensor 10 is located inside the watch strap 3, passes through the watch strap 3 to the inside of the monitoring body 1, and is electrically connected to the display screen 12, so that the display screen 12 can display the data in real time.

[0027] The working principle of this utility model is as follows: When in use, the watch strap 3 itself is made of elastic rubber material, and one end of the watch strap 3 is fixed inside the monitoring body 1 through the fixing head 7. The other end of the watch strap 3 is designed with multiple sets of teeth on one side, and can be inserted into the monitoring body 1 through the insertion port 2. A gear 5 is installed at the connection between the monitoring body 1 and the insertion port 2, and the teeth on the watch strap 3 and the teeth of the gear 5 can mesh with each other.

[0028] Therefore, when the user wears it, the monitoring unit 1 can be placed on the wrist, and then the watch strap 3 can be wrapped around the wrist and inserted into the monitoring unit 1 through the insertion port 2. At this time, the knob 11 is turned, which drives the rotating shaft 4 to rotate, thereby driving the gear 5 to rotate. The gear 5 meshes with the teeth on the watch strap 3, so that the user's wrist can be fastened and the monitoring unit 1 can be fixed on the user's wrist.

[0029] Furthermore, when the knob 11 is turned, one end of the watch strap 3 will gradually move into the monitoring body 1 under the rotation of the gear 5. At this time, the airbag 6 will be squeezed. When the airbag 6 is squeezed, the first air chamber 8 will also be squeezed, and the gas in it will move into the second air chamber 9, thereby opening the airbag 6 located outside the monitoring body 1, so that the bottom of the airbag 6 is in close contact with the user's wrist, further locking the user's wrist, so that the sensor 10 inside the watch strap 3 can be in close contact with the user's pulse, avoiding gaps that would affect real-time monitoring.

[0030] After the sensor 10 is attached to the user's pulse, it will record it in real time. The cable of the sensor 10 is located inside the strap 3, and it leads to the inside of the monitoring body 1 through the strap 3 and is electrically connected to the display screen 12, so that the display screen 12 can display the data in real time.

[0031] Meanwhile, the airbag 6 itself is made of elastic material. After the second air chamber 9 is expanded by gas, the airbag 6 fits tightly against the user's wrist, so it will not tighten the user's wrist excessively and will not cause discomfort to the user.

[0032] The above structure solves the technical problem that the monitoring device cannot fit snugly against the wrist after being worn, thus affecting real-time monitoring, while locking the strap would cause discomfort to the user over a long period of time.
