[0007] According to an embodiment of the present invention, the wearable wireless dynamic cardiac function monitoring device includes a connecting rod and a rotating rod. The connecting rod is located in the middle of the storage slot. One end of the rotating rod is rotatably engaged with the connecting rod, and the other end is rotatably engaged with the sliding shaft. The connecting rod can move closer to or further away from the storage slot so that the sliding shaft can slide.

[0008] The wearable wireless dynamic cardiac function monitoring device provided in the embodiments of the present invention further includes an adjustment component, which includes a gear, a pair of racks and a base. A mounting cavity is opened in the middle of the mounting frame, the adjustment component is disposed in the mounting cavity, the base is connected to the racks, the pair of racks and the base are centrally symmetrically arranged, and the gear meshes with the racks.

[0009] According to an embodiment of the present invention, the wearable wireless dynamic cardiac function monitoring device includes an adjustment component comprising a stabilizing rod and a rotating handle. One end of the stabilizing rod is connected to a gear, and the other end is connected to the rotating handle. The stabilizing rod passes through the mounting frame.

[0010] According to the wearable wireless dynamic cardiac function monitoring device provided in the embodiment of the present invention, the adjustment component further includes an auxiliary fixing component. An inner cavity is opened inside the base, and the auxiliary fixing component is disposed in the inner cavity. The auxiliary fixing component includes an adhesive block. A through groove is opened on the side wall of the base, the through groove is connected to the inner cavity, the adhesive block is disposed in the through groove, and the adhesive block is slidably engaged with the wall surface of the through groove.

[0011] According to an embodiment of the present invention, the wearable wireless dynamic cardiac function monitoring device includes an auxiliary fixing component comprising a fixing frame and a limiting rod. A limiting groove is provided on the fixing frame. One end of the limiting rod is connected to an adhesive block, and the other end is slidably engaged with the limiting groove, which is inclined.

[0012] According to the wearable wireless dynamic cardiac function monitoring device provided in the embodiment of the present invention, the auxiliary fixing component also includes a lever. A sliding groove is formed on the base. One end of the lever is connected to the fixing frame, and the other end is slidably engaged with the wall of the sliding groove. The lever can slide in the sliding groove so that the fixing frame can slide.

[0013] According to an embodiment of the present invention, the wearable wireless dynamic cardiac function monitoring device includes a monitoring component including a charging port and a control button. The charging port is located on one side of the mounting frame and is electrically connected to the monitoring sensor and the finger monitor.

The device is further secured by controlling the position of the adhesive block. Adhesive can be applied to the side wall of the adhesive block, allowing the side wall with the adhesive to slide towards the side with the suction cups. The device is then adhered to the patient's body using the adhesive, thus achieving a secure fixation effect. The two ends of the mounting frame are secured by the suction cups. A traction rope moves the piston towards the bottom wall of the receiving slot, causing the piston to extract air from the suction cups, creating a negative pressure environment. The suction force of the suction cups then secures the device to the patient's body. This design allows for easy disassembly and installation by medical personnel, improving efficiency and stability, and replacing the reliance on fixing straps, avoiding the adverse effects of inaccurate monitoring data due to poor fixation.

[0020] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] Please see Figures 1 to 12 This invention provides a wearable wireless dynamic cardiac function monitoring device, including a mounting frame 200, a monitoring component 100, and a wearable component 400.

[0023] The monitoring component 100 includes a monitoring sensor 110 and a finger monitor 120. The monitoring sensor 110 is disposed on one side of the mounting frame 200 and the finger monitor 120 is disposed on the other side. The monitoring sensor 110 and the finger monitor 120 are used to monitor the patient's cardiac function. The wearable component 400 includes a sliding shaft 410, a piston 420 and a suction cup 430. The suction cup 430 is disposed next to the monitoring sensor 110. A storage groove 201 is formed in the side wall of the mounting frame 200. A sliding groove 203 is formed in the side wall of the storage groove 201. The sliding shaft 410 slides in the sliding groove 203. An air hole 204 is formed on the bottom wall of the storage groove 201. The air hole 204 is connected to the suction cup 430. The piston 420 is disposed in the air hole 204. The sliding shaft 410 is connected to the piston 420 through a traction rope 460. The sliding shaft 410 can slide in the sliding groove 203 so that the piston 420 can slide in the air hole 204.

[0024] It should be noted that the mounting frame 200 has a cuboid structure. The monitoring sensor 110 and the finger monitor 120 are mounted opposite each other on the two walls of the mounting frame 200 to monitor the patient's cardiac function and obtain the patient's vital signs information. There are multiple monitoring sensors 110, arranged in an array on the mounting frame 200. The suction cup 430 and the monitoring sensor 110 are located on the same wall of the mounting frame 200, and the suction cup 430 is symmetrically arranged on both sides of the monitoring sensor 110.

[0025] It should be understood that when a patient presses their hand on the finger monitor 120, the monitor captures changes in microcirculatory blood volume at the fingertip caused by heartbeat and converts them into electrical signals. Through long-term, continuous analysis of the waveform, rhythm, and characteristics of this signal, multiple parameters related to cardiac function, such as heart rate, heart rate variability, blood oxygen saturation, blood pressure trends, and cardiac pumping efficiency, can be calculated, enabling long-term, convenient trend tracking and risk assessment of the user's cardiovascular health.

[0026] The slide groove 203 is opened along the length of the mounting frame 200, and the air hole 204 is opened in an "L" shape so that the air hole 204 connects to the suction cup 430, and the specifications and dimensions of the piston 420 are adapted to the air hole 204. When the sliding shaft 410 slides away from the air hole 204, the traction rope 460 can drive the piston 420 to move closer to the bottom wall of the receiving groove 201, so that the piston 420 draws out the air in the suction cup 430, creating a negative pressure environment in the suction cup 430, thereby fixing the device to the patient's body through the suction force of the suction cup 430. When the sliding shaft 410 slides closer to the air hole 204, the traction rope 460 can drive the piston 420 away from the bottom wall of the receiving groove 201, so that the air pressure in the suction cup 430 returns to normal pressure, thereby losing the suction force, making it easier for medical personnel to disassemble the device.

[0027] According to an embodiment of the present invention, the wearable wireless dynamic cardiac function monitoring device includes a wearable component 400 comprising a connecting rod 440 and a rotating rod 450. The connecting rod 440 is located in the middle of the storage groove 201. One end of the rotating rod 450 is rotatably engaged with the connecting rod 440, and the other end is rotatably engaged with the sliding shaft 410. The connecting rod 440 can move closer to or further away from the storage groove 201 so that the sliding shaft 410 can slide.

[0028] It should be noted that in this embodiment, there are two sets of wearable components 400, symmetrically arranged on both sides of the mounting frame 200. One end of the rotating rod 450 is hinged to the connecting rod 440, and the other end is hinged to the sliding shaft 410. The storage groove 201 is used to store the connecting rod 440 and the rotating rod 450. The connecting rod 440 is located in the middle of the storage groove 201, and the rotating rods 450 are symmetrically arranged at both ends of the connecting rod 440. The connecting rod 440 can approach or move away from the bottom wall of the storage groove 201. When the connecting rod 440 moves away from the bottom wall of the storage groove 201, the rotating rod 450 rotates, and at the same time drives the sliding shaft 410 to slide away from the air hole 204, so that the piston 420 draws out the air from the suction cup 430. When the connecting rod 440 approaches the bottom wall of the storage groove 201, the rotating rod 450 rotates, and at the same time drives the sliding shaft 410 to slide towards the air hole 204, so that the air pressure in the suction cup 430 returns to normal pressure. The depth of the storage slot 201 is adapted to the rotating rod 450. Both the rotating rod 450 and the connecting rod 440 can be placed against the bottom wall of the storage slot 201, thereby storing the rotating rod 450 and the connecting rod 440 in the storage slot 201.

[0029] The wearable wireless dynamic cardiac function monitoring device provided in the embodiments of the present invention further includes an adjustment component 300. The adjustment component 300 includes a gear 310, a pair of racks 320 and a base 330. A mounting cavity 202 is opened in the middle of the mounting frame 200. The adjustment component 300 is disposed in the mounting cavity 202. The base 330 is connected to the racks 320. The pair of racks 320 and the base 330 are centrally symmetrically arranged. The gear 310 meshes with the racks 320.

[0030] It is important to understand that the adjustment component 300 is used to assist in fixing the device and adjusting the position of the connecting rod 440. Specifically, the tail of the rack 320 is connected to the base 330. A pair of racks 320 are centrally symmetrically arranged, with gears 310 installed at the symmetrical points. Gears 310 are installed at both ends of the mounting frame 200. When one rack 320 abuts against the other base 330, it can limit the rack 320, ensuring that both the rack 320 and the base 330 are within the mounting cavity 202. The base 330 contacts the connecting rod 440. When the gear 310 rotates, the rack 320 moves along the width of the mounting frame 200. The two bases 330 can move closer to or further away from each other, allowing the bases 330 to move the connecting rod 440 closer to or further away from the bottom wall of the storage slot 201. This controls the internal air pressure of the suction cup 430, facilitating the patient's wearing or removal of the device.

[0031] According to an embodiment of the present invention, the wearable wireless dynamic cardiac function monitoring device includes an adjustment component 300 comprising a stabilizing rod 340 and a rotating handle 350. One end of the stabilizing rod 340 is connected to a gear 310, and the other end is connected to the rotating handle 350. The stabilizing rod 340 passes through the mounting frame 200.

[0032] It should be noted that the mounting frame 200 has holes, and the position of the stabilizing rod 340 corresponds to the hole. The tail of the stabilizing rod 340 is connected to the rotating handle 350. In use, rotating the rotating handle 350 will drive the gear 310 to rotate, and the rack 320 and the base 330 will move accordingly, thereby pushing the connecting rod 440 out of the storage slot 201 or retracting it into the storage slot 201. At the same time, because of the cooperation between the gear 310 and the rack 320, the base 330 and the connecting rod 440 can move straight up and down without offset, avoiding the adverse effect of inconsistent air pressure in the suction cups 430 at both ends due to the different positions of the pistons 420 on both sides, which would cause unstable adsorption.

[0033] According to the wearable wireless dynamic cardiac function monitoring device provided in the embodiment of the present invention, the adjustment component 300 further includes an auxiliary fixing member 360. An inner cavity 331 is opened inside the base 330, and the auxiliary fixing member 360 is disposed in the inner cavity 331. The auxiliary fixing member 360 includes an adhesive block 361. A through groove 332 is opened on the side wall of the base 330, the through groove 332 communicates with the inner cavity 331, the adhesive block 361 is disposed in the through groove 332, and the adhesive block 361 slides and engages with the wall surface of the through groove 332.

[0034] It should be noted that the through groove 332 is opened along the thickness direction of the mounting base 330 so that when the base 330 extends out of the mounting cavity 202, medical staff can push one end of the adhesive block 361 out of the through groove 332. In this embodiment, adhesive can be provided on the side wall of the adhesive block 361. The side wall with adhesive can slide towards the side where the suction cup 430 is installed. The device is attached to the patient's body by the adhesive, thereby achieving the effect of auxiliary fixation. Thus, the two ends of the mounting frame 200 are fixed by the suction cup 430, and the middle part is fixed by the adhesive block 361 and adhesive, ensuring the fixation effect when the patient wears it and overcoming the drawback of relying on the fixation strap to fix the cardiac function monitoring device.

[0035] According to the embodiments of the present invention, the wearable wireless dynamic cardiac function monitoring device includes an auxiliary fixing component 360, which includes a fixing frame 362 and a limiting rod 364. A limiting groove 363 is provided on the fixing frame 362. One end of the limiting rod 364 is connected to the adhesive block 361, and the other end is slidably engaged with the limiting groove 363. The limiting groove 363 is opened at an angle.

[0036] It should be noted that the fixing frame 362 is a cuboid structure with a slot in the middle. The fixing frame 362 has symmetrical limiting slots 363 on the top and bottom. The adhesive block 361 is set inside the fixing frame 362 and is located in the through slot 332. The adhesive block 361 slides along the through slot 332, and the limiting block slides along the inclined limiting slot 363. When the fixing frame 362 slides to the left and right, the adhesive block 361 can slide back and forth along the through slot 332 so that the adhesive side of the adhesive block 361 slides out of the through slot 332 and comes into contact with the patient's body, thereby sticking the device to the appropriate part of the patient's body to achieve the effect of auxiliary fixation.

[0037] According to the wearable wireless dynamic cardiac function monitoring device provided in the embodiment of the present invention, the auxiliary fixing component 360 further includes a lever 365, and a sliding groove 333 is formed on the base 330. One end of the lever 365 is connected to the fixing frame 362, and the other end slides in cooperation with the wall of the sliding groove 333. The lever 365 can slide in the sliding groove 333 so that the fixing frame 362 can slide.

[0038] It should be understood that the lever 365 is used to slide the fixing frame 362, which can slide within the inner cavity 331. The sliding groove 333 connects to the inner cavity 331, allowing the lever 365 to extend beyond both the inner cavity 331 and the sliding groove 333 for use by medical personnel. Sliding the lever 365 causes the fixing frame 362 to slide along the length of the mounting frame 200, allowing the adhesive block 361 to move closer to or further away from the patient's body. The wall of the sliding groove 333 also has a limiting effect on the lever 365. The through groove 332 is adapted to the size of the adhesive block 361. When the lever 365 drives the fixing frame 362 to slide, the limiting effect of the limiting groove 363 and the through groove 332 ensures that the adhesive block 361 can only slide back and forth without lateral displacement, facilitating operation by medical personnel.

[0039] According to an embodiment of the present invention, the wearable wireless dynamic cardiac function monitoring device includes a monitoring component 100 comprising a charging port 130 and a control key 140. The charging port 130 is disposed on one side of the mounting frame 200 and is electrically connected to the monitoring sensor 110 and the finger monitor 120. The control key 140 is used to control the monitoring sensor 110 and the finger monitor 120. Both the monitoring sensor 110 and the finger monitor 120 are wirelessly connected to electronic devices.

[0040] It should be understood that the charging port 130 is used to connect to an external power source, which can charge the monitoring sensor 110 and the finger monitor 120 through the charging port 130. The control key 140 can control the monitoring sensor 110 and the finger monitor 120 to be turned on and off, and at the same time connects the monitoring sensor 110 and the finger monitor 120 to an external electronic device via Bluetooth signal, thereby obtaining the patient's vital signs information.

[0041] In summary, this invention provides a wearable wireless dynamic cardiac function monitoring device, including a mounting frame 200, a monitoring component 100, and a wearable component 400. The monitoring component 100 includes a monitoring sensor 110 and a finger monitor 120, both mounted on the mounting frame 200. In use, the monitoring sensor 110 is placed close to the patient's body, while the finger monitor 120 is located away from the patient's body. Medical personnel need to adjust the device's position appropriately so that the monitoring sensor 110, which has ultrasound emission and echo reception functions, is embedded in the wearable garment. Its position can be adjusted according to the size and location of the patient's heart, ensuring natural and close contact between the monitoring sensor 110 and the patient's skin. After position adjustment, the device is fixed to the patient's body using the wearable component 400 and the adjustment component 300. The wearable component 400 uses the internal air pressure of the suction cup 430 to attach the mounting frame 200 to the patient's body, thus stabilizing both ends of the mounting frame 200. Simultaneously, adjusting the component 300 stabilizes the middle of the mounting frame 200, ensuring the device is securely fixed to the patient's body. This allows the monitoring component 100 to acquire more accurate data, facilitating accurate diagnosis and assessment of the patient's condition by medical personnel. Finally, after activating the monitoring sensor 110 and finger monitor 120 via the control key 140, the monitoring sensor acquires the patient's cardiac function parameters. Simultaneously, the patient presses their palm onto the finger monitor 120, which captures changes in microcirculatory blood volume at the fingertips caused by heartbeat and converts this data into electrical signals. By conducting long-term and continuous analysis of the waveform, rhythm, and characteristics of this signal, multiple data such as heart rate, heart rate variability, blood oxygen saturation, blood pressure trend, and cardiac pumping efficiency can be calculated. These data are then converted into electrical signals and transmitted to electronic devices via wireless transmission technologies such as Bluetooth for doctors to diagnose and assess, enabling long-term and convenient trend tracking and risk assessment of the user's cardiovascular health.
