[0002] A finger-cuff-type blood pressure, blood oxygen, and heart rate measuring device is a commonly used instrument for monitoring vital signs. When using it, the user only needs to place a finger in the finger cavity to obtain the pulse rate and blood oxygen saturation value. Because existing finger-cuff-type blood pressure, blood oxygen, and heart rate measuring devices use the inflation and deflation of an air bag to clamp and fix the finger, and the user's finger is not protected during the insertion of the finger cuff, the user's nails may scratch or rip the air bag, reducing the service life of the air bag. In addition, the position of the detection light in the finger cuff is usually fixed, and the finger is not limited during the insertion process, so the finger is prone to tilt. When the user's finger is tilted, it will affect the detection accuracy of the device. Based on this, the present application proposes a finger-cuff-type blood pressure, blood oxygen, and heart rate measuring device. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] The present invention provides a finger-cuff-type blood pressure, blood oxygen, and heart rate measuring device, comprising a device body 1 and a finger cuff 2. An airbag 7 is disposed within the inner cavity of the finger cuff 2, and an end cap 11 is disposed on the outer side of the inner cavity of the finger cuff 2. The end cap 11 is detachably connected to the finger cuff 2, facilitating replacement of the airbag 7 when the end cap 11 is separated from the finger cuff 2. The device body 1, finger cuff 2, airbag 7, and end cap 11 constitute a finger-cuff-type oximeter known in the prior art, capable of measuring a user's blood pressure, blood oxygen, and heart rate. The operating principle of the finger-cuff-type oximeter is known in the prior art and will not be described in detail here.
[0022] The airbag 7 is an I-shaped structure. The outer diameter of the middle part of the airbag 7 is smaller than the outer diameter of its end parts. A cavity is formed between the middle part of the airbag 7 and the inner wall of the finger sleeve 2, and the outer surface of the airbag 7 is wrapped with a thermal pad. The material of the thermal pad is a material that expands when inflated and contracts when deflated. The material can be selected according to needs and is not limited here.
[0023] The inner cavity of the finger cuff 2 is provided with a protective assembly and a heat-insulating assembly. The protective assembly includes a fixed block 3 fixedly connected to the finger cuff 2 and a movable block 5 movably connected to the inner cavity of the airbag 7. The fixed block 3 and the movable block 5 are connected via a spring 12 and a telescopic guide rod 4. One end of the spring 12 and the telescopic guide rod 4 are fixedly connected to the fixed block 3, while the other end of the spring 12 and the telescopic guide rod 4 are fixedly connected to the movable block 5. The movable block 5 is movably connected to the inner cavity of the end cap 11. Due to the arrangement of the spring 12, the movable block 5 can be moved to the outside of the finger cuff 2 under the action of the spring 12's rebound force. Under external pressure, the distance between the movable block 5 and the fixed block 3 can be reduced. The telescopic guide rod 4 guides the movable block 5, allowing it to move in the direction of the telescopic guide rod 4.
[0024] The end of the movable block 5, away from the fixed block 3, is evenly and fixedly connected to a spacer plate 9. A nail placement space is formed between two adjacent spacers 9, and the outer surface of each spacer plate 9 is covered with an isolation pad, which can be made of rubber. The provision of the nail placement space allows the user to insert their fingernail into the space during use. The space conceals the user's nail, preventing the user's fingernail from scratching the airbag 7 during insertion into the inner cavity of the finger sleeve 2. The space also limits the length of the user's nail, preventing the device from being used if the user's nail is too long, thus ensuring its reliability.
[0025] An electromagnet 6 is fixedly connected to one side of the fixed block 3 close to the movable block 5. When the electromagnet 6 is in the energized state, the electromagnet 6 and the movable block 5 are magnetically attracted to each other. Through the setting of the electromagnet 6, the operation of the electromagnet 6 can actively reset the movable block 5, avoiding the user using the fingertips to push the movable block 5 to move.
[0026] The heat preservation component includes a tactile sensor 13 fixedly connected to the movable block 5 and an electric heating wire mesh 8 located in the cavity. Through the setting of the electric heating wire mesh 8, the heat emitted by the electric heating wire mesh 8 when it is energized can keep the user's fingertip to be tested warm, avoiding the detection result of the device being affected by the fingertip being too cold. The sensor unit 10 of the tactile sensor 13 is set at the end of the isolation plate 9 away from the movable block 5. Through the setting of the tactile sensor 13, the temperature of the user's fingertip can be detected, and it can be determined whether the user's fingertip is in close contact with the isolation plate 9.
[0027] From the above description, it can be seen that when the device is in use, the user's nails can be hidden in the nail placement space to prevent the nails from scratching or breaking the airbag 7, thereby protecting the airbag 7. In addition, during the detection process, the user's fingertips are in a tightly fitted state with the isolation plate 9, so that the fingertips of different users can be located at the same position in the finger cuff 2, making it convenient for the device to detect the user's blood pressure, blood oxygen and heart rate.
[0028] In summary: before using the fingertip type blood pressure, blood oxygen and heart rate measuring device, under the action of the rebound force of the spring 12, the nail placement space is located outside the fingertip 2, and the user inserts the nail into the nail placement space at an appropriate height according to needs. If the nail contacts the movable block 5 and the user's fingertip does not contact the isolation plate 9, the user's nail is too long, or the user's nail protrudes outside the nail placement space, and the user needs to trim the nail. After the nail is trimmed appropriately, the user reinserts the nail into the nail placement space until the user's fingertip is tightly fitted with the isolation plate 9. The user starts the device. When the user's fingertip is tightly fitted with the isolation plate 9, the electromagnet 6 is in an energized state. The energization of the electromagnet 6, The electromagnet 6 and the movable block 5 are magnetically attracted to each other. Under the action of the suction force, the movable block 5 gradually approaches the fixed block 3 until the movable block 5 is reset. During this process, the user's fingertips and the movable block 5 are in a relatively static state. The tactile sensor 13 uses the sensor unit 10 to detect the temperature of the user's fingertips. When the fingertip temperature is too low, the electric heating wire mesh 8 works to increase the temperature inside the finger cuff 2 and keep the user's fingertip warm, which facilitates the device to measure the user's blood pressure, blood oxygen and heart rate. After the detection is completed, the device is in a closed state, the electromagnet 6 is powered off, and under the action of the rebound force of the spring 12, the movable block 5 moves outward until the nail placement space is located outside the finger cuff 2, and the user can separate the finger from the device.
