Description
Technical field
The utility model relates to medical instruments fields, more particularly to a kind of portable multi-function lung function instrument.
Background technique
Respiratory disease is clinical common disease, typical such as Chronic Obstructive Pulmonary Disease (COPD) at home each
City disease incidence is up to 5%~13%, and with the continuous aggravation of Chinese aging, disease incidence will constantly rise.It is clinical
It confirms that pulmonary function detection is to diagnose the important evidence of COPD, is the objective standard for judging flow limitation, diagnosis, disease to lung function
Disease progression, prognosis and therapeutic response etc. are significant.Necessity inspection of the pulmonary function test as respiratory disease, for
Early detection lung, airway lesions assess coincident with severity degree of condition and the prognosis of disease, evaluate the treatment of drug or other treatment methods
Effect, the reason of identifying expiratory dyspnea, diagnosis diseased region, assessment lung function to the tolerance or labor intensity tolerance of operation and
There is important directive significance to the monitoring etc. of urgent patient.
There are some operations, storage currently on the market, with the pulmonary function detection equipment of medical platform interaction, but detection is set
Standby often all volume is larger, expensive, and can not portable mobile, domestic monitoring cannot be applicable in and that guards whenever and wherever possible want
Ask, but pulmonary function detection is to pursue the accurate of result, generally require intraday different periods to the lung function of patient into
Row repeated detection, it is inaccurate so as to cause measurement result if patient, which leaves home to work or play outside etc., will affect adversely the opportunity of detection
Really, doctor can not be assisted to treat patient.
End-tidal CO2 concentration or the detection for dividing (ETCO2) can then reflect pulmonary ventilation, can also reflect lung blood flow, be a kind of
The atraumatic technique for detecting lung function (especially pulmonary ventilation function) is enabled a physician to bedside is continuous, quantitative detection patient, to exhale
Desorption system disease patient carries out Breathing Suppotion and respiratory nursing provides clear index.In clinical application, can also auxiliary diagnosis, one
Aspect, the pulmonary ventilation volume and lung blood flow ratio of lung embolism patients obviously lack of proper care, seriously affect the gas exchanges of alveolar and blood, lead
Alveolar dead space is caused to dramatically increase.Therefore the real-time change of carbon dioxide waveform figure, the case where being able to reflect out alveolar dead space, lead to
Partial pressure of carbon dioxide in endexpiratory gas monitoring is crossed, can be the diagnosis of pulmonary embolism disease according to the Long-term change trend of carbon dioxide waveform figure
It provides effective foundation.On the other hand, for obstructive disease of lung patient, capnography is with normal pulmonary function or suffers from
The patient of restrictive lung disease has notable difference, and parameters are also closely related with the severe degree of the state of an illness.Therefore, clinical
On to will test end expiratorycarbon dioxide be an important monitoring program.
There are two types of the mode of monitoring end-expiratory carbon dioxide is current, one is with end-expiratory carbon dioxide detection module
Ventilator or Anesthesia machine, however the only critical or sick Talents employing ventilator for needing to anaesthetize or Anesthesia machine, ventilator and fiber crops
Liquor-saturated machine function is complicated, and structural volume is larger, and common breathing patient does not need ventilator or Anesthesia machine, thus ventilator or
Person's Anesthesia machine checks that patient's use cost of end-expiratory carbon dioxide is larger for general, and simultaneously inconvenient, another
The mode for detecting end-expiratory carbon dioxide is common multi-parameter monitor, is generally used for bedside monitoring, can real-time monitoring patient
Physiological parameter, it is bigger to equally exist equipment volume, and medical staff is not suitable for transportation of patients etc. and is lacked using inconvenient to carry
It falls into.
The Portable lung function detection device that existing market has been developed, main includes two kinds: turbine type, heat-sensitive type.
Wherein mechanical signal, by photoelectric effect, is converted to electric signal using electro-optical modulation principle using turbine sensor by turbine type
Output, because the factors such as turbines into motion inertia and frictional force, will affect sensor accuracy, causes detection accuracy error big.In addition
One kind is heat-sensitive type lung function instrument, needs linearity correction, sensitive to gas componant, is not durable, expensive.Then, existing
A kind of lung function instrument based on ultrasonic technology is proposed in technology, is mainly detected by every lung function index to patient, energy
COPD and related lung function disease are enough early diagnosed out, still, existing ultrasonic wave lung function instrument, not portable enough, structure is set
It is equipped with limitation, is mainly manifested in since ultrasonic wave gas chamber is arranged inside detection device, unreasonable, Bu Nengman is arranged in pipe diameter size
The requirement of sufficient detection accuracy；In addition, due to ultrasound signal transmission by propagation medium, environment (temperature, humidity, pressure) etc. because
The a variety of causes such as reflection occur in gas pipeline for element and ultrasonic wave, and usually there is waveform changes for the ultrasonic signal received
Change, amplitude variation, has an impact to measuring accuracy, cause to test unstable.
Therefore, it is necessary to design, one kind is easy to carry, and detection is accurate, the high lung function instrument of cost performance, to solve above-mentioned skill
Art problem.
