Problems solved by technology

[0003] At present, the measurement of tidal volume in human physiological experiments needs to be connected to a computer for measurement through multiple devices such as a breathing mask, airflow filter, sensor, and airflow tube. Not only is it troublesome to wear, but also due to the small exhalation port and long pipeline, As a result, the pressure is higher when exhaling, and the exhalation is incomplete. In the state of long-term exercise, the air output is larger, which is easy to cause respiratory acidosis, and the measurement results are inaccurate; the longer airflow tube will also hinder the human body during exercise. sports

Embodiment 1

[0033] Such as Figure 1-3 As shown, an airflow sensor includes a housing 1, a flap 2, a support rod 3, a sliding block 4, a pressure sensor 5 with a wireless communication function and a stretchable pressure transmission strip 6, and the housing 1 is connected at both ends Cylindrical housing structure, the inner wall of the housing 1 is provided with a chute 7, the pressure sensor 5 is arranged at one end of the chute 7, and one side of the sliding block 4 passes through the pressure transmission bar 6 Connected to the detection end of the pressure sensor 5, the sliding block 4 is matched with the chute 7 and slidably arranged in the chute 7, and the side of the sliding block 4 away from the pressure sensor 5 is supported by The rod 3 is connected to the blocking piece 2, one end of the supporting rod 3 is hinged to the blocking piece 2, the other end of the supporting rod 3 is fixedly connected to the sliding block 4, and the blocking piece 2 is connected to the inner diame...

Embodiment 2

[0041] Such as Figure 1-4 As shown, this embodiment is a breathing mask with an airflow sensor in Embodiment 1, including a breathing mask body 8, a connection hole is provided at the front center of the breathing mask body 8, and the airflow sensor 9 is connected to the airflow sensor through the connection hole. The airflow sensor 9 is connected to the main body 8 of the breathing mask, and one end of the flap 2 of the airflow sensor 9 is arranged close to the main body 8 of the breathing mask. The two sides of the connection hole are respectively symmetrically provided with one-way valves 10 for inhalation. The valve 10 communicates with the mask body.

[0042] During use, the respiratory mask body 8 is worn and starts to breathe normally. Due to the existence of the retaining ring 13 during inhalation, the restriction flap is opened during inhalation, and the air can only be fed through the one-way valve 10. The pressure is too high, so the one-way valve 10 is closed and...

Embodiment 3

[0046] The present embodiment is a method for measuring tidal volume based on the breathing mask in Embodiment 2, comprising the following steps:

[0047] S10: Wear a breathing mask; breathe through the breathing mask;

[0048] S20: Open the flap 2; the exhaled gas acts on the flap 2, and the flap 2 rotates under pressure;

[0049] S30: push the sliding block 4; during the rotating process of the blocking plate 2, the sliding movement is driven by the support rod 3 towards the direction of the pressure sensor 5;

[0050] S40: pressure transmission; the sliding block 4 squeezes the pressure transmission bar 6 during the movement process, and the pressure transmission bar 6 transmits the pressure signal to the pressure sensor 5;

[0051] S50: signal transmission; the pressure sensor 5 transmits the pressure signal to the computer through wireless communication;

[0052] S60: Calculate the tidal volume; the computer calculates the tidal volume according to the pressure signal t...

Abstract

The invention discloses an airflow sensor. The airflow sensor comprises a shell, a blocking piece, a supporting rod, a sliding block, a pressure sensor with a wireless communication function and a telescopic pressure conveying strip. The invention also discloses a breathing mask equipped with the airflow sensor. The breathing mask comprises a breathing mask body, wherein a connecting hole is arranged at the center position of the front surface of the breathing mask body; the airflow sensor is connected with the breathing mask body through the connecting hole; and one-way valves are symmetrically arranged at two sides of the connecting hole respectively. The invention also discloses a tidal volume measuring method based on the breathing mask. The tidal volume measuring method comprises thesteps of wearing of the breathing mask, opening of the blocking piece, pushing of the sliding block, pressure transmission, signal transmission and calculation of a tidal volume. According to the invention, the one-way valves and the airflow sensor are arranged on the breathing mask body, so traditional tidal volume measuring equipment is simplified, and only the breathing mask body needs to be worn; and wearing is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an airflow sensor, a breathing mask with the sensor and a method for measuring tidal volume. Background technique [0002] Tidal volume (Tidal volume, TV) refers to the volume of air inhaled or exhaled each time during quiet breathing, and it is related to age, gender, volume surface, breathing habits, and body metabolism. The set tidal volume usually refers to the inspiratory volume. The setting of tidal volume is not constant and should be adjusted according to the patient's blood gas analysis. Under normal circumstances, adults: 8-10ml / kg, children: 6-10ml / kg. [0003] At present, the measurement of tidal volume in human physiological experiments needs to be connected to a computer for measurement through multiple devices such as a breathing mask, airflow filter, sensor, and airflow tube. Not only is it troublesome to wear, but also due to the small exhalation port a...
