Description
Technical field
This utility model relates to medical Instrument field, specifically is used for the diagnosis of the disease relevant with the lungs sound auscultation.
Background technology
Lungs sound has very important significance for the diagnosis of respiratory system disease especially infantile pneumonia etc., clinically the processing of lungs sound generally still is in the stage of judging by rule of thumb type.Carry out multi-region collection and intelligent decision to clinical significant for patient's lungs sound feature.At present the utility model people is by a large amount of clinical infantile pneumonia patients' lungs sound analysis, established the Objective Analysis Method that carries out the infantile pneumonia diagnosis by lungs sound and also implemented.
Utility model people has accumulated many experiences in the long-term practice process of infantile pneumonia being carried out diagnosis and treatment, think that the analysis of auscultation and lungs sound is extremely important or main means in infantile pneumonia diagnosis and the therapeutic evaluation, to patient's state of an illness diagnosis, analysis of drug use and recovery from illness interpretation all have very important significance.In order to carry out this research, utility model people carries out for many years lungs sound collection and relevant case history recording of information to clinical infantile pneumonia case, and various clinical typical lungs sounds have been carried out feature analysis, to setting up a kind of lungs sound analytical method and the taxonomic methods effective to the infantile pneumonia patient, combine with clinical information, can instruct accurately the clinician to carry out the analysis of lungs sound and the interpretation of the state of an illness.
For infantile pneumonia, what mainly will study is the common improper lungs sounds such as sound, wheezing sound, large, medium and small bubble of stridulating.Although existing lungs sound analytical method has tens kinds, be applied in the lungs sound analysis of infantile pneumonia and find that employing a certain method wherein all can not well well be distinguished these pathologic lungs sounds separately.Some methods are too limited to the analysis of frequency domain or time domain, bad assurance feature; Some methods are too complicated and theorize, and are also undesirable for the solution of particular problem.Process is with the careful analysis of clinician to great amount of samples, think that the comprehensive analysis method that the analysis in the performance of pure mathematics analysis means and physics is combined is to carry out the effective ways that the infantile pneumonia lungs sound is analyzed, this also is the analysis means that this utility model is determined, has obtained good analysis result in clinical analysis.This utility model utilizes acoustoelectric sensor and radio electron echometer to carry out the lungs sound collection specifically, utilizes personal computer to adopt the lungs sound classification and Detection algorithm based on the graphical analysis of STFT short-term spectrum to come to have doing ring sound and bubble etc. the lungs sound of clinical important diagnostic meaning to carry out automatic analysis and distinguish.
Existing lungs sound detector generally only has the acquisition testing function of lungs sound, the analytic function that does not relate to several typical lungs sounds, number be 200610154521.8 such as Chinese patent application, it number is 98230423.4 that name is called " networked blood pressure/pressure/heartbeat/body temperature/heart and lung sounds comprehensive detector " and Chinese patent application, is called " heart rate/pulmonary sound telephone remote-control instrument ".Chinese patent application number is 201010107997.2, name is called " the portable and visual heart, the separable Bluetooth electronic stethoscope of lungs sound " and can carries out uploading of the collection of hear sounds lungs sound, elementary filtering and heart rate calculating and demonstration and lungs sound, but does not relate to the lungs sound analysis.Chinese patent application number is 200680009502.4, and name is called " visual stethoscope " and can carries out uploading of the collection of hear sounds lungs sound, elementary filtering and heart rate calculating and demonstration and lungs sound, but does not relate to the lungs sound analysis.Chinese patent application number is 201020215584.1, name is called the determination and analysis that " Intelligent cardiopulmonary analyzing instrument " device relates to the hear sounds lungs sound, its heart and lung sounds sensor is contact-type piezoelectric membrane pickup sheet, employing comprises dsp processor, the AD converting unit, the elements such as sound driver chip adopt cepstrum coefficient method and HMM model algorithm to analyze, and its acquisition component and mode, main processing unit are all fully different from this patent with analytical method.
The utility model content
The characteristics such as the purpose of this utility model provides a kind of lungs sound automatic analyzer, adopts this utility model that lungs sound is carried out Clinical detection, has in real time, and is efficient and accurate.
The technical scheme that adopts is:
A kind of lungs sound automatic analyzer comprises diagnostic apparatus main frame, three lungs sound probe and radio electron echometers that are equiped with acoustoelectric sensor; It is characterized in that:
The diagnostic apparatus main frame comprises a diagnostic computer and signal amplifier;
Signal amplifier is connected with the corresponding interface of main frame by wire; Three lungs sounds are popped one's head in by the signal output part sub-connection of wire and signal amplifier;
Radio electron echometer is connected with the corresponding interface of main frame by wireless transmission.
Be equiped with USB interface, network interface and audio output interface on the described main frame.
Using method:
Before the detection, select first " detecting in real time " or " file detection " detection mode, then select to detect data.Detect beginning after confirming.If the employing lungs sound is popped one's head in then detected in real time, gather Lung Sounds and provide simultaneously testing result; If adopt radio electron echometer then the select File detection, testing result is the analysis result of the lungs sound file of selection.
Operational instances:
To being examined the people, first 3 lungs sound probes are placed on respectively 3 back lungs sound detection zones of patient, fix, connecting line is connected to the sensor interface of control device.By button and display screen selection " the real-time detection " mode and 3 passages, press the Lung Sounds waveform that " beginning to detect " key is determined 3 passages of rear control device meeting instant playback.Each passage can select one section Lung Sounds to analyze after pressing " stopping to detect " key, and acquiescence is with the data analysis of collection in last 8 seconds.Concrete analysis data and classified prompt are presented on the liquid crystal display screen.The lungs sound data can be selected a certain passage to carry out repeatedly playback and play sound by audio amplifier.
Radio electron echometer can be by wireless transmission or special purpose interface with the lungs sound file transfer to control device, then select " file detection " mode to obtain the analysis result of certain lungs sound file.
The utility model has the advantage of:
1. all respiratory system diseases all will gather lungs sound, and the multi-region of lungs sound gathers simultaneously with automatic analysis has important meaning for detecting the additional lungs sound of pathologic, thereby patient's diagnoses and treatment is all had very great help.
