BLOOD PRESSURE MEASURING DEVICE

Title:

BLOOD PRESSURE MEASURING DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/016739

Kind Code:

A1

Abstract:

A blood pressure measuring device, comprising a device body, an air bag (4), an air nozzle (3) and a piston (2); an air pump (5) is provided in the device body, a housing (1) of the device body is provided with a mounting hole (11) and an air channel connection hole (12) in communication with the mounting hole (11), the air channel connection hole (12) is in communication with an air outlet of the air pump (5), the piston (2) is mounted in the mounting hole (11), the piston (2) is provided with a piston sealing portion capable of forming a seal with the mounting hole (11) located above the air channel connection hole (12), the air nozzle (3) is provided with a through hole (35) in communication with the air bag (4), and when the air nozzle (3) is inserted into the mounting hole (11), the piston (2) is pressed down until the piston sealing portion is located below the air channel connection hole (12), and the through hole (35) is in communication with the air channel connection hole (12). The blood pressure measuring device uses the piston (2) to move up and down in the mounting hole (11) and to cooperate with the air channel connection hole (12), achieving that the device body can have a waterproof function when the air bag (4) is removed in the case that the air bag (4) is not used at ordinary times; and when blood pressure needs to be measured, the air nozzle (3) of the air bag (4) is connected, so that the blood pressure can be measured normally.
