Description

Technical Field

[0001] This utility model relates to the field of spirometry technology, and in particular to a spirometer. Background Technology

[0002] Spirometers, as important medical and health monitoring devices, are widely used in hospitals, sports training facilities, and homes to measure an individual's maximum expiratory volume (i.e., vital capacity). Traditional spirometer designs typically include a simple tubular structure into which the user blows to measure their lung capacity. However, this traditional design has limitations, such as low measurement accuracy, a lack of adaptability to individual user needs, and inconvenient data reading and analysis.

[0003] Many spirometers on the market still lack an effective gas flow rate regulation mechanism, which means they cannot well adapt to the breathing characteristics of different users or adjust the measurement conditions according to specific needs. Summary of the Invention

[0004] This invention addresses the problems of existing technologies by providing a spirometer that adjusts the cross-sectional area of ​​gas passing through the expiratory tube by rotating an outlet adjustment component. Turning the outlet adjustment component outward increases the area, while turning it inward decreases the area, thereby changing the pressure of the gas passing through and causing a change in the data sensed by the gas pressure sensor. This allows technicians or users to easily adjust the measurement accuracy of this invention.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a spirometer, which includes a housing, a measuring mask mounted on one side of the housing, a control panel mounted on the upper end of the housing, and a control circuit board mounted inside the housing. An exhalation tube and a detection tube are disposed inside the housing. An exhalation port is provided on one side of the housing, and the exhalation port communicates with the upper end of the exhalation tube. One end of the measuring mask is detachably connected to the exhalation port. A pressure sensor is disposed on the control circuit board. One end of the detection tube is connected to one side of the exhalation tube and communicates with the exhalation tube. The other end of the detection tube is connected to the pressure sensor. An air outlet is provided at the lower end of the exhalation tube, and the air outlet is exposed at the lower end of the housing. An air outlet adjustment component is rotatably disposed at the lower end of one side of the exhalation tube, and one end of the air outlet adjustment component protrudes into the exhalation tube from the lower end of one side of the exhalation tube.

[0007] The control panel includes a touch screen and control buttons, which are electrically connected to the control circuit board.

[0008] The lower end of the housing is also equipped with a battery compartment.

[0009] The air outlet adjustment component is an adjustment screw, which is threadedly connected to the lower end of one side of the exhalation tube.

[0010] The beneficial effects of this utility model are:

[0011] This invention features a novel structure. The measuring mask is designed to fit snugly against the user's face. One end of the mask is attached to the exhalation port and then connected to the exhalation tube. During lung capacity measurement, the user wears the mask over their mouth and face, exhales through the exhalation port, and the gas enters the exhalation tube. The gas is expelled through the outlet and simultaneously enters the detection tube. The pressure of the gas passing through the detection tube is measured by connecting it to a pressure sensor, causing a change in the data sensed by the gas pressure sensor. This invention allows for adjustment of the cross-sectional area of ​​the gas passing through the exhalation tube by rotating the outlet adjustment component. Twisting the outlet adjustment component outward increases the area, while twisting it inward decreases the area, thereby changing the pressure of the gas passing through and causing a change in the data sensed by the gas pressure sensor. This allows technicians or users to easily adjust the measurement accuracy of this invention. Attached Figure Description

In this embodiment, the cross-sectional area of ​​the gas passing through the exhalation tube 4 is adjusted by rotating the air outlet adjustment component 8. Turning the air outlet adjustment component 8 outward increases the area, and turning it inward decreases the area, thereby changing the pressure of the gas passing through and causing the data sensed by the gas pressure sensor 12 to change.
