Description

Technical Field

[0001] This utility model relates to the field of blood pressure monitoring technology, specifically to an integrated wireless blood pressure monitoring device. Background Technology

[0002] The blood pressure monitoring module is a core component of medical devices, primarily used for automatically measuring human blood pressure parameters. It is widely used in devices such as patient monitors and blood pressure cuffs. The core working principle of the blood pressure monitoring module is to block blood flow by applying pressure to an external cuff, and then obtain blood pressure values ​​by combining pressure changes with signal characteristics.

[0003] Most existing patient monitors use wired blood pressure monitoring modules, which are placed inside the monitor and connected to an external blood pressure extension tube and cuff. Traditional blood pressure modules rely on the extension tube to connect the monitor and the patient, which restricts the patient's range of motion and the cable is prone to tangling with other parameter cables. Wireless modules, on the other hand, have a loose structure and low integration, with each module housed in an independent casing, resulting in a larger overall size. Furthermore, wireless module casings often use a single ventilation hole design, which, while alleviating circuit overheating, provides poor dust and water resistance. Moisture and dust can easily enter the casing through the ventilation holes, creating a conflict between heat dissipation and sealing, making them unsuitable for humid or dusty clinical environments.

[0031] like Figures 1-5 The diagram illustrates an integrated wireless blood pressure monitoring device, comprising a cuff 20 and a wireless blood pressure monitoring control module connected to the cuff 20. The wireless blood pressure monitoring control module includes a housing, a blood pressure monitoring component installed within the housing, a heat dissipation structure 9, a pressurization component 11, and a portable power supply. Specifically, the housing includes a detachably connected upper shell 3 and a lower shell 13, with a sealing ring connecting the upper shell 3 and the lower shell 13, and a communicating heat dissipation channel within the housing; the heat dissipation structure 9 is fitted to the blood pressure monitoring component; the wireless transmission component 8 is signal-connected to the blood pressure monitoring component; the pressurization component 11 is connected to the cuff 20 via an air tube 22, and the pressurization component 11 is adapted to transmit air gaps into the cuff 20 to generate pressure fluctuations in the cuff 20; the portable power supply is electrically connected to the pressurization component 11.

A sealing ring connects the upper shell 3 and lower shell 13, and the shell has no ventilation holes to prevent moisture and dust from entering, thus ensuring its airtightness. A heat dissipation structure 9 fitted to the blood pressure monitoring component disperses the heat. A connected heat dissipation channel inside the shell further disperses the heat, preventing the blood pressure monitoring component from burning out due to overheating. The inclusion of a portable power supply and wireless transmission component 8 prevents excessive wiring from affecting the user's range of motion.

[0033] In this embodiment, the blood pressure monitoring component includes a main control board 5, a blood pressure plate 4, and a main control chip 10 fixed on the main control board 5. A heat dissipation structure 9 has a relief groove with the same thickness and width as the main control chip 10, and the heat dissipation structure 9 covers the outer periphery of the main control chip 10.

Specifically, the heat dissipation structure 9 is a graphene heat sink. This configuration allows the heat from the main control chip 10 to be quickly dissipated through the graphene heat sink, and the heat dissipation efficiency can be further improved by combining it with the heat dissipation channels inside the casing. Specifically, a pressure sensor is provided on the blood pressure plate 4. This configuration allows for real-time capture of changes in the air pressure within the cuff 20, thereby outputting a microvolt-level analog signal to the main control board 5.

[0034] In this embodiment, the pressurizing assembly 11 includes an inner shell, a pressurizing component disposed within the inner shell, and a driving component connected to the pressurizing component. The pressurizing component is connected to the cuff 20. This configuration, by separating the driving component from the main control board 5 through the inner shell, reduces the transmission of vibrations generated during the movement of the driving component and the pressurizing component to the circuitry. Simultaneously, by placing the driving component and the pressurizing component within the inner shell, noise generated during their operation can be suppressed.

[0035] Specifically, the inner shell includes a detachably connected upper fixed shell 1101 and a lower fixed shell 1102. The lower fixed shell 1102 is provided with a first damping pad located below the pressurizing component and a second damping pad located below the driving component.

This arrangement can effectively improve the installation and connection efficiency of the shell and the cuff 20. Specifically, the slide rail 18 is a U-shaped slide rail 18, and protruding positioning blocks 16 are provided on opposite sides of one end of the fixed slider 19. This arrangement prevents the shell from being inserted from the end with the positioning blocks 16, thus ensuring that the shell can only be inserted in one direction and avoiding misinstallation. Specifically, the U-shaped slide rail 18 is a stainless steel magnetic slide rail 18, and a neodymium iron boron magnet is embedded in the lower shell 13. This arrangement can improve the connection strength and connection stability between the wireless blood pressure monitoring and control module and the cuff 20.

[0038] In this embodiment, the cuff 20 is also provided with a Velcro 21 and an air tube 22 located on one side of the Velcro 21, and the air tube 22 is provided with a connector 23.

This arrangement, through the cooperation of the fixing buckle 17 and the fixing hole 24, ensures the connection stability between the outer shell and the cuff 20, preventing the outer shell from falling off the cuff 20 during use. Specifically, the end of the lower shell 13 is also provided with an air nozzle socket suitable for connecting the air pipe 22 connector 23.

[0040] In this embodiment, an antenna 14 electrically connected to the wireless transmission component 8 is also provided inside the upper shell 3. The antenna 14 and the pressure component are located at two diagonal positions inside the upper shell 3. This arrangement, which keeps the antenna 14 away from the pressure component, avoids signal attenuation caused by the electromagnetic field generated during the operation of the pressure component, thus improving the performance and electromagnetic compatibility of the antenna 14. Specifically, the wireless transmission component 8 is a Bluetooth / Wi-Fi dual-mode chip fixed to the inner wall of the upper shell 3. This arrangement separates the Bluetooth / Wi-Fi dual-mode chip and the antenna 14 from the main control board 5 through a graphene heat sink, ensuring sufficient isolation space between the Bluetooth / Wi-Fi dual-mode chip, the antenna 14, and the main control board 5, thereby guaranteeing the radiation efficiency of the antenna 14.

[0041] In this embodiment, the power bank is a large-capacity battery 7 with a capacity of 2500ml-5000ml.
