Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 , figure 2 As shown, a smart phone-based lung function sensor includes a sensor 9 and a smart phone 6. The sensor 9 includes a housing 2, a mouthpiece 1, blades 4 and a bracket 5, wherein the bracket 5 is fixed in the housing 2, and the upper end of the bracket 5 is The runner is fixed, and several blades 4 are fixed on the runner. The blowing nozzle is arranged on the upper end of the casing 2, and the casing 2 is provided with a hole, and the position of the hole 3 corresponds to the blade 4; the hole 3 is placed above the camera 7 of the mobile phone.

[0018] The two sides of the blade 4 are respectively painted with different colors.

[0019] In order to further strengthen the accuracy of identification, the two sides of the blade 4 are respectively painted in black and white.

[0020] The side of the casing 2 provided w...

Abstract

The invention discloses a smart phone based pulmonary function sensor. The pulmonary function sensor comprises a sensor and a smart phone. The sensor comprises a casing, a blowing nozzle, blades and a support. The support is fixed in the casing, a rotation wheel is fixed at the upper end of the support, a plurality of blades are fixed on the rotation wheel, the blowing nozzle is arranged at the upper end of the casing, a hole is formed in the casing, and the position of the hole is corresponding to the positions of the blades, and the hole is formed above a phone camera. By means of the pulmonary function sensor, electronic circuits are absent, the fabrication cost is low, faults cannot occur easily, and the product can have huge market space along with the wide popularization of phones.

Description

technical field [0001] The invention relates to a smart phone-based pulmonary function sensor. Background technique [0002] At present, pulmonary function testing has become a must in the diagnosis and evaluation of diseases such as asthma and chronic obstructive pulmonary disease. [0003] In view of the bulky and cumbersome lung function testing instruments used in clinical diagnosis, in order to facilitate daily testing of patients, some professional manufacturers have launched portable lung function testing instruments. The lung function instrument realized by mobile phone that appears on the market is one of them. The principle is to input the electrical signal generated by the lung function sensor into the mobile phone, and the computer or mobile phone calculates the detection result. [0004] However, the sensor of this type of spirometer produces electrical signals, so the sensor must have structures such as a power supply and an electronic circuit, which are cost...
