[0036] Please refer to Figure 1-Figure 5 , this embodiment provides a multifunctional restraint belt 100, including a restraint belt body 110, a tightening assembly 120 and a detection assembly 130;

[0037] The restraint belt body 110 is used to wrap around the upper limbs or lower limbs of the user, and both ends of the restraint belt body 110 are connected to the tightening assembly 120, and the tightening assembly 120 is used to tighten or release the restraint belt body 110, so that the restraint belt body 110 can be tightly tied to the upper limbs or lower limbs of the user;

[0038] The detection component 130 is connected to the restraint belt body 110 or the tightening component 120 , and is used to detect one or more of the user's blood pressure, heart rate and blood oxygen.

[0039] It should be noted that in this embodiment, the detection component 130 is used to detect the user's blood pressure, heart rate and blood oxygen. In other embodiments of the utility model, the multifunctional restraint belt 100 can also realize one or more of the blood pressure, heart rate and blood oxygen detection according to the needs of use, or implement other detections other than the aforementioned detection items. In addition, the restraint belt body 110 is made of soft and breathable medical materials, such as medical-grade polyester fiber materials, and its length and width can be adjusted according to the patient's body shape.

[0040] Please refer to Figure 1-Figure 5 The working principle of the multifunctional restraint belt 100 is:

[0041] The multifunctional restraint belt 100 includes a restraint belt body 110, a tightening assembly 120 and a detection assembly 130;

[0042] The restraint belt body 110 is used to wrap around the upper limbs or lower limbs of the user, and both ends of the restraint belt body 110 are connected to the tightening assembly 120, and the tightening assembly 120 is used to tighten or release the restraint belt body 110, so that the restraint belt body 110 can be tightly tied to the upper limbs or lower limbs of the user;

[0043] Therefore, through such a setting, the tightening component 120 can be used to tighten the restraint belt body 110 so that the restraint belt body 110 is tightly tied to the upper limbs or lower limbs of the user, and then when it is in the tightened state, it is convenient for the detection component 130 to detect one or more of the user's blood pressure, heart rate and blood oxygen; in other states, the tightening component 120 can be used to release the restraint belt body 110 to reduce the restraining pressure of the restraint belt body 110 on the upper limbs or lower limbs of the user, thereby avoiding affecting the user's blood circulation.

[0044] Therefore, since the tightness of the multifunctional restraint belt 100 can be adjusted, it can play an effective restraint role to ensure the stability of wearing and use, and can also avoid affecting the user's blood circulation.

[0045] For further information, please refer to Figure 1-Figure 5 In this embodiment, when the tightening assembly 120 is configured, the tightening assembly 120 includes a connecting block 121, a tightening motor 122, a transmission belt 123 and two movable blocks 124;

[0046] The connecting block 121 is bent and provided with an arc-shaped strip movable hole 125; the two ends of the restraining belt body 110 are respectively connected to the two movable blocks 124; the two movable blocks 124 can be slidably arranged in the strip movable hole 125, and the two movable blocks 124 are both transmission-connected to the tightening motor 122 through the transmission belt 123;

[0047] The tightening motor 122 is used to reel in the transmission belt 123 to drive the two movable blocks 124 to move closer to or farther from each other in the strip movable hole 125 to reel in or release the restraining belt body 110 .

[0048] Through the above-mentioned structural setting, the tightening motor 122 can be controlled to work, and then the transmission belt 123 can be reeled in, so as to drive the two movable blocks 124 to move closer to or farther from each other in the strip movable hole 125, so as to reel in or release the restraint belt body 110. It should be noted that when the multifunctional restraint belt 100 is used, it is used by being set on the upper limbs or lower limbs of the user. Therefore, when the tightening motor 122 of the tightening assembly 120 is controlled to release the restraint belt body 110, it can control the release amount to reduce the restraining pressure of the restraint belt body 110 on the upper limbs or lower limbs of the user, and it can also be convenient to remove it from the upper limbs or lower limbs of the user.

[0049] In addition, when the transmission belt 123 is set, it can be a winding rope, and the initial positions of the two movable blocks 124 are located at the two ends of the bar movable hole 125, so that the transmission belt 123 can be wound up by the tightening motor 122, thereby driving the two movable blocks 124 to approach each other, and when the transmission belt 123 is configured, the position where the transmission belt 123 is connected to the tightening motor 122 can be located in the middle of the bar movable hole 125, and the winding position of the transmission belt 123 connected to the two movable blocks 124 on the tightening motor 122 is located on both sides of the rotating end of the tightening motor 122, so that the movement of the rotating end of the tightening motor 122 can wind up the transmission belt 123 on the movable blocks 124 located on both sides thereof.

[0050] In addition, based on the above structure, in order to facilitate disassembly and assembly, so as to facilitate replacement of the restraint belt body 110, and thus facilitate cleaning and disinfection, the tightening assembly 120 further includes two connecting buckles 126; the two connecting buckles 126 are respectively connected to the two movable blocks 124, and the two ends of the restraint belt body 110 are respectively connected to the two connecting buckles 126. Through such a setting, the restraint belt body 110 is detachably connected to the two movable blocks 124 through the connecting buckles 126, so that the replacement and disassembly of the restraint belt body 110 can be facilitated. At the same time, such a setting method also facilitates the replacement of the restraint belt body 110 of different lengths, so as to adapt to different users.

[0051] For further information, please refer to Figure 1-Figure 5 In this embodiment, in order to increase the retracted amount of the restraint belt body 110, that is, the adjustment range of its length, the connection block 121 is provided with a channel 127 for the connection buckle 126 and the restraint belt body 110 to pass through, and the channel 127 is bent; the strip-shaped movable holes 125 are arranged on both sides of the channel 127. With such a setting, when the tightening motor 122 is operated to retract the transmission belt 123, and then the two movable blocks 124 are brought close to each other, the connection buckle 126 and the restraint belt body 110 can be moved in the channel 127, thereby expanding the adjustment range.

[0052] Please refer to Figure 1-Figure 5 In this embodiment, when configuring the detection component 130, the detection component 130 is connected to the connection block 121, and the detection component 130 is connected to the inner side of the connection block 121, that is, located on the side of the connection block 121 that is used to contact the user's skin. In other embodiments of the utility model, when the detection component 130 is connected to the restraint belt body 110, a corresponding installation groove can be set on the restraint belt body 110.

[0053] In addition, in this embodiment, the detection component 130 includes one or more of a blood pressure detection sensor 131, a heart rate detection sensor 132, and a blood oxygen detection sensor 133. The blood pressure detection sensor 131, the heart rate detection sensor 132, and the blood oxygen detection sensor 133 are used to detect the user's blood pressure, heart rate, and blood oxygen, respectively. In this embodiment, the detection component 130 includes the blood pressure detection sensor 131, the heart rate detection sensor 132, and the blood oxygen detection sensor 133, and the blood pressure detection sensor 131, the heart rate detection sensor 132, and the blood oxygen detection sensor 133 are sequentially arranged at intervals around the bending direction of the connection block 121.

[0054] In addition, in order to detect the damping of the winding of the tightening motor 122 during its rotation, the tightening assembly 120 includes an electronic torque sensor, which is connected to the connecting block 121 and is used to detect the torque of the tightening motor 122. By detecting the torque of the tightening motor 122, the pressure of the restraint belt body 110 on the user can be deduced, so that when the pressure is too large, the user is prompted to release the restraint belt body 110 to reduce the pressure, or the restraint belt body 110 is automatically released.

[0055] For further information, please refer to Figure 1-Figure 5 Based on the above structure, in order to transmit the data detected by the detection component 130 and facilitate the detection and control of the detection component 130, the multifunctional restraint belt 100 also includes a battery, a communication module and a control board connected to the connection block 121; the battery, the communication module, the electronic torque sensor and the detection component 130 are all electrically connected to the control board, and the communication module is used to communicate with an external control terminal or a mobile terminal. The battery can power the aforementioned structure, and the communication module communicates with the external control terminal or the mobile terminal, so that data can be transmitted to the outside and external control instructions can also be received.

[0056] It should be noted that, from the above content, it can be seen that in this embodiment, since a control board is provided, and the control board is electrically connected to the communication module, the electronic torque sensor and the detection component 130, the detection component 130 can be controlled by the control board to collect the patient's blood pressure, heart rate, blood oxygen and other vital signs data in real time, and the collected data can be transmitted to an external control terminal or a mobile terminal through the communication module. Moreover, since it is provided with an electronic torque sensor, when the torque of the tightening motor 122 is too large, the tightening motor 122 can be selectively controlled to reverse according to whether it is in a detection state, so as to release the main body, thereby reducing the pressure exerted on the patient, thereby ensuring that the tightness of the restraint belt is always within a safe range.

[0057] For further information, please refer to Figure 1-Figure 5 In the process of use, in order to quickly release the restraint belt body 110 or make the multifunctional restraint belt 100 quickly disassemble and assemble, the restraint belt body 110 includes a first belt body 111 and a second belt body 112, and one end of the first belt body 111 is detachably connected to one end of the second belt body 112. When realizing the detachable connection between one end of the first belt body 111 and one end of the second belt body 112, Velcro can be used for bonding, or a buckle structure can be used, and the ends of the first belt body 111 and the second belt body 112 that are away from each other are respectively connected to the two movable blocks 124.

[0058] In summary, please refer to Figure 1-Figure 5 The steps for using the multifunctional restraint belt 100 are as follows:

[0059] According to the patient's body shape, select a restraint belt body 110 of appropriate size;

[0060] Wrap the restraint belt body 110 around the patient's wrist or ankle and connect it to the connecting buckle 126 on the connecting block 121, so that the restraint belt body 110 and the connecting block 121 are in close contact with the skin;

[0061] The control instructions are sent to the control board through the operation panel on the connection block 121 to control the detection component 130 and the tightening component 120 to work.

[0062] It should be noted that, in this embodiment, when configuring the connection block 121, it can be made of flexible materials so that its bending curvature can be adaptively adjusted to suit different patients, and all materials meet the safety and biocompatibility requirements of medical devices and are strictly sterilized.

[0063] In addition, please refer to Figure 1-Figure 5The blood pressure detection sensor 131 in this embodiment can adopt a piezoresistive or capacitive pressure sensor with a measuring range of 0-300mmHg and an accuracy of ±3mmHg; the heart rate detection sensor 132 can adopt a photoelectric capacitance pulse wave sensor with a measuring range of 30-250bpm and an accuracy of ±2bpm; the blood oxygen detection sensor 133 can adopt a reflective pulse blood oxygen sensor with a measuring range of 0-100% and an accuracy of ±2%; the above sensors are all connected to the control board through a flexible cable; the tightening motor 122 can adopt a micro DC motor and a gear set to provide the power required for adjusting the tightness of the restraint belt body 110, and the motor driver chip can adopt an H-bridge motor driver chip, such as L298N, to control the forward and reverse rotation of the motor; the main control board can adopt a low-power, high-performance microcontroller, such as the STM32L series, which is responsible for data processing and control; the communication module can adopt a low-power Bluetooth BLE4.0 module for communicating with external devices; the battery can be powered by a lithium battery with built-in charging management and power management chips.
