Abstract
The utility model relates to a stethoscope used for auscultation and diagnosis in clinical care, which is composed of a chest piece, emulsion tubes, a metal support, and earplugs. The utility model is characterized in that a computer control circuit device which is composed of a sound transducer, a sound alarm integrated block, a sound recognition integrated block, a four-bit microprocessor and a four-bit liquid crystal display is arranged in the membrane type chest piece. Double emulsion tubes and a metal tee connector are adopted. Thus the conductance of various acoustic frequencies and the resolution of auscultation are increased. The utility model with the functions of digital display of heart rate, alarm for upper limit and lower limit of normal heart rate, detection and alarm for malposition heart rate, memory and analysis of a computer, etc., can effectively raise the level of clinical diagnosis and therapy.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of stethoscope that is used for clinical treatment auscultation and diagnosis.
Stethoscope commonly used now is made up of membrane type chest piece, metal rack, monodisperse latex pipe, earplug, membrane type chest piece inside is cavity, diaphragm is stamped in the front, the intravital hear sounds of patient, respiratory murmur, friction sound etc. import earplug into by diaphragm-operated vibration, the doctor can only diagnose patient's disease according to strong, the weak and readability of its acoustical signal, this stethoscope conductivity to all kinds of audio frequency in clinical practice is relatively poor, auscultation resolution is low, function singleness can't provide in time medical diagnosis, quantizating index accurately and reliably.
The purpose of this utility model is the single for many years backward situation of stethoscope for a change, adapts to the needs of medical science development, and develops a kind of have computer apparatus, multi-functional stethoscope.
The purpose of this utility model is achieved through the following technical solutions:
A kind of computer multi-function stethoscope is made up of membrane type chest piece, latex tubing, metal rack earplug and computer-controlled circuit device, it is characterized in that:
Computer-controlled circuit is arranged in the base of membrane type chest piece, by sound transducer, the audible alarm integrated package, the voice recognition integrated package, four bit microprocessors, four liquid crystal displays constitute, sound transducer is connected to the frequency divider end of voice recognition integrated package, acoustical signal is carried out integration, sampling, contrast, amplify, through the main door trigger of this integrated package to signal analysis, send into four bit microprocessors behind row's sign indicating number and release sign indicating number, the signal of telecommunication of its output triggers the action of audible alarm integrated package, shows that on four liquid crystal displays four liquid crystal displays are connected by conductive adhesive layer with four bit microprocessors simultaneously;
The front of membrane type chest piece housing is provided with diaphragm and cavity, is provided with magnet ring along diaphragm-operated circumference, is connected to the three way cock by joint, and the pore in the joint feeds cavity;
Latex tubing is the two-tube of parallel connection, and its two ends are connected with three way cock and metal rack respectively.
At the basal surface position of membrane type chest piece four liquid crystal displays and alarm lamp, power supply indicator are set; The housing of membrane type chest piece is separable upper and lower two partly, between connect by screw thread or buckle; Diaphragm can be fixed on outer covering, and combines with membrane type chest piece housing by screw thread or buckle.
According to the computer multi-function stethoscope that the utility model proposes, on existing stethoscopic basis, critical pieces such as its membrane type chest piece are all improved, change into existing latex single tube two-tube, be equipped with the metal three way cock, strengthen the conductivity of all kinds of audio frequency greatly, improved clinical auscultation resolution; On membrane type chest piece base, be provided with the computer-controlled circuit device, have the heart rate numeral and show that the normal cardiac rate upper and lower limit is reported to the police, dystopy heart rate (premature beat) detection alarm, computer memory is analyzed, functions such as audio frequency (respiratory murmur, friction sound, hear sounds etc.) increase and decrease is adjustable also can be carried out power supply and be shown and alarm indicator, and are rational in infrastructure, novel, volume is little, multiple functional, can instruct effectively and improve the clinical diagnosis treatment level, and for teaching with medical diagnosis provides in time, accurate, reliable quantizating index.
