Description
Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to a respiratory device for clinical diagnosis and detection in internal medicine of traditional Chinese medicine.
Background
Respiration refers to the process of gas exchange between the body and the external environment. The human respiratory process includes three interrelated links: external breathing, including lung ventilation and pulmonary ventilation; transport of gas in blood; internal respiration refers to the exchange of gas between the tissue cells and the blood. A normal adult breathes optimally for 6.4 seconds at rest, and the volume of gas inhaled and exhaled each time is approximately 500 ml, called the tidal volume. When people inhale by force until the people can not inhale any more; then exhale with force again, exhale until can't exhale again, the gas volume that this moment exhales is called vital capacity, detect breathe to measure patient's gas that exhales, generally use expiration analysis meter to measure.
The breath analyzer can detect the content of helicobacter pylori in the exhaled gas of a patient, and in the past, a gastroscope or even a gastric tissue biopsy is needed, so that both can bring certain pain, and many patients have difficulty and psychological fear. It is for this reason that many patients delay the optimal treatment period by dragging the disease over time. Moreover, helicobacter pylori is often in the shape of a kitchen in the stomach, and the biopsy result can be influenced, so that the detection result is not accurate enough, the detection time is greatly shortened due to the appearance of the exhalation analyzer, the pain of a patient caused by detection is greatly reduced, the detection efficiency is improved, the mask is buckled at the mouth of the patient during detection, the power supply of the analyzer is turned on, then the patient exhales towards the mask, gas enters the analyzer through a conduit, an air bag and the like for detection, and the detection result can be obtained within several minutes generally.
However, there are still some unreasonable factors in the detection of breathing in the current breath analyzers, which are used: the patient uses face guard, gasbag and pipe to exhale, and the time measuring is examined to the inside of incoming call analysis appearance, can detect the inside air incoming call analysis appearance that has existed originally of face guard, gasbag and pipe, and the inside air that has existed originally of face guard, gasbag and pipe can dilute the gas of patient's incoming call usually, leads to the testing result on the low side, and the practicality is relatively poor.
