Technical Field

[0001] This utility model relates to the field of electronic blood pressure monitor technology, specifically to an airtight mechanism for an electronic blood pressure monitor. Background Technology

[0002] Blood pressure, as one of the most important vital parameters for human health, is a crucial indicator for clinical diagnosis, monitoring treatment effectiveness, and prognosis. Electronic blood pressure monitors are medical devices that measure blood pressure using modern electronic technology and the principle of indirect blood pressure measurement. Their emergence has made them convenient for patients to use and has become a primary tool for home blood pressure monitoring.

[0003] Currently, the airtight components inside electronic blood pressure monitors are key to ensuring accurate blood pressure measurement. Existing electronic blood pressure monitors cannot guarantee airtightness during use, which affects the measurement results. Utility Model Content

[0010] A further improvement to the above solution is that limit blocks are provided at both ends of the housing near the driver to limit the installation of the driver.

[0011] A further improvement to the above solution is that the outer shell is provided with an airtight hole, and one end of the airtight connector is installed in the airtight hole and connected to the drive box.

[0012] A further improvement to the above solution is that the driver has pins at both ends, one end of which is close to the charging connector, and the other end is located inside the driver box and sealed by a first sealing ring.

[0013] A further improvement to the above solution is that the drive box is provided with a mating groove near the airtight joint, and the mating groove is used to mate with the second sealing ring and seal the installation ring.

[0014] The beneficial effects of this utility model are:

[0015] Compared to existing electronic blood pressure monitors, this invention uses a protective outer shell, which is not only sturdy and durable but also cleverly accommodates all internal components.

The charging connector 20 is located on one side of the outer shell 10, making it convenient for users to charge the device at any time and keep it running continuously. The PCB board 30, as the control core of the electronic blood pressure monitor, is electrically connected to the charging plug at one end, ensuring a stable and reliable power supply. The driver 40 is located inside the outer shell 10 and is tightly connected to the airtight component 50 at one end. The first sealing ring 52 and the driver box 41 form the first line of sealing defense. The airtight component 50, together with the second sealing ring 53, forms the second sealing structure, further enhancing the airtight performance of the entire mechanism. Through the double sealing design, airtightness is ensured.

[0029] A fixing clip 11 is provided on the side of the outer casing 10 near the PCB board 30. The fixing clip 11 is used to securely engage the PCB board 30. In this embodiment, the effective fixing and engaging of the fixing clip 11 with the PCB board 30 enhances the structural stability of the airtight mechanism of the electronic blood pressure monitor, ensuring that the PCB board 30 is not easily loosened or displaced during use, thereby guaranteeing the normal operation of the equipment and the accuracy of the measurement.
