Description

Technical Field

[0001] The utility model relates to the field of sphygmomanometers, and more specifically, to a handheld mechanical sphygmomanometer. Background Art

[0002] A sphygmomanometer is a diagnostic medical device for measuring human blood pressure, which has the characteristics of small size and portability. Its use effect is the same as that of a mercury column sphygmomanometer, and it adopts a mercury-free design for blood pressure measurement. When the existing handheld sphygmomanometer is in use, the air duct of the arm cuff part is inserted into the air nozzle of the handheld sphygmomanometer and pulled out when not in use. When plugging in, the air duct is sleeved on the air nozzle and tightly sleeved on the air nozzle by the elastic force of the air duct itself to form a fixed and sealed connection. During long-term use, the connection end of the air duct and the air nozzle will gradually be stretched and enlarged, resulting in loose connection and decreased sealing performance. Moreover, with this existing structure, it is also rather laborious to insert and pull out the air duct.

[0003] Chinese Patent Application No.: CN202220762945.7 provides a high-precision handheld sphygmomanometer. In this solution, the connection operation between the air duct and the sphygmomanometer body is simple and convenient. During operation, the movable tube is inserted into the connection sleeve. After insertion, the movable tube is rotated, and the slider rotates to a position misaligned with the chute, so that the slider and the limit ring can cooperate to restrict the movable tube from disengaging from the connection sleeve. Its disassembly and assembly are simple and the operation is convenient.

[0004] However, in a specific environment, due to different usage requirements, users need to switch between using the left and right hands. When some sphygmomanometers are switched between using the left and right hands, it is not conducive to users' operation. The sphygmomanometer is prone to interfering with users' operation and is inconvenient to use. Therefore, a handheld mechanical sphygmomanometer is proposed to solve the above problems. Summary of the Utility Model
