Problems solved by technology

[0003] However, many subjects with normal respiratory muscle function did not master the essentials of inhaling forcefully or were confused, resulting in the measured maximum inspiratory pressure being too low, leading to clinical misjudgment
At the same time, because the catheter needs to be inserted into the subject, and the catheter needs to be connected with complex instruments, the operation is difficult and it is easy to cause trauma to the subject.

Embodiment 1

[0024] like figure 1 As shown, the non-invasive respiratory muscle function detector includes a mask 1 sealed with the face of the human body, a pressure detector 2, a catheter 3, a three-way pipe 4, an air storage bag 5 filled with carbon dioxide, a control module 7 and a valve mechanism 6 The pressure detector 2 communicates with the face mask 1 through the conduit 3; the first nozzle 41 of the three-way pipe 4 communicates with the mask 1, and the second nozzle 42 of the three-way pipe 4 communicates with the air storage bag 5 , the third nozzle 43 of the three-way pipe 4 communicates with the outside air; the three-way valve 8 is provided in the three-way pipe 4; the pipeline 44 between the three-way valve 8 and the first nozzle 41 and the valve The mechanism 6 is connected; the valve mechanism 6 and the pressure detector 2 are both connected with the control module. Wherein, the carbon dioxide in the gas storage bag 5 accounts for 8% by volume of the gas in the gas stora...

Embodiment 2

[0029] The difference between this non-invasive respiratory muscle function detector and embodiment 1 is: as figure 2 As shown, the valve mechanism 6 is a solenoid valve, which is installed in the pipeline 44 between the three-way valve 8 and the first nozzle 41, and the solenoid valve is connected with the control module. The solenoid valve can respond to the signal instructions of the PLC in a more timely manner, thereby ensuring the accuracy of the detection structure.

Embodiment 3

[0031] The difference between the non-invasive respiratory muscle function detector and the embodiment 1 is that: the gas storage bag is filled with the gas whose volume percentage of carbon dioxide is 5%. This reduces the concentration of carbon dioxide, although the detection speed will be slowed down, but the comfort of the test subject can be improved.

Abstract

The invention discloses a non-invasive respiratory muscle function detector which comprises a mask in sealed connection with a human face, a catheter, a tee pipe, a gas storage bag filled with carbon dioxide, a control module and a valve mechanism, wherein a pressure detection gauge is communicated with the mask through the catheter; a first pipe opening of the tee pipe is communicated with the mask; a second pipe opening of the tee pipe is communicated with the gas storage bag; a third pipe opening of the tee pipe is communicated with external air; a three-way valve is arranged in the tee pipe; a pipeline between the three-way valve and the first pipe opening is connected with the valve mechanism; the valve mechanism and the pressure detection gauge are connected with the control module. According to the invention, the non-invasive respiratory muscle function detector is high in detection accuracy and simple to operate, and cannot hurt trial subjects.

Description

technical field [0001] The invention relates to detection technology equipment, in particular to a non-invasive respiratory muscle function detection instrument. Background technique [0002] Respiratory muscles are the power source of human breathing, and their fatigue and weakness can lead to dyspnea or even respiratory failure. Clinically, many unexplained shortness of breath is caused by abnormal function of respiratory muscles. Detection of respiratory muscle function has important clinical value. At present, when testing respiratory muscle function, it is necessary to insert a catheter containing a thin-walled air bag into the lower part of the esophagus from the subject's nose, and indirectly reflect the function of the respiratory muscle through changes in the internal pressure of the air bag. During the test, the subject needs to inhale as hard as possible. [0003] However, many subjects with normal respiratory muscle function did not master the essentials of fo...
