Abstract
The utility model relates to a multifunctional stethoscope. On the basis of the common stethoscope, the back side of the chestpiece of the stethoscope is provided with an electronic time recorder, and the side surface of the chestpiece is additionally provided with two single clamp ear pieces for two to three persons to auscultate simultaneously; one earphone is connected with a solid recording device, and a disposable sterilizing film is used at the membranous part of the chestpiece to prevent the cross infection. The utility model can gather many people to auscultate simultaneously, is a multifunctional stethoscope which can have the timing and recording functions and has the advantages of reasonable structure, perfect function and convenient use and carrying.
Description
This utility model relates to a kind of medical diagnosis utensil, particularly stethoscope.
Stethoscope now prolongs the old fashioned of having used many decades basically.There are many people to attempt old-fashioned stethoscope to be transformed, increase stethoscopic function by the whole bag of tricks.Chinese patent 91213991.9 has been announced a kind of novel stethoscope, at stethoscopic chest piece back electronic timer is housed, and can see the table counting in auscultation, and is very convenient during auscultation.But it is not quick detachable, clean, sterilization, and function singleness, can not adapt to the needs of the medical industry of current develop rapidly.
The purpose of this utility model is at the deficiencies in the prior art, design, make a kind of for many people auscultations simultaneously, again Timing, record in the multi-function stethoscope of one.
Technical solution of the present utility model is: on the stethoscopic basis of using now, at the stethoscopic chest piece back side electronic timer is housed,, sets up two single joint receivers in the side of chest piece, can be for 2-3 people auscultation simultaneously, available again one of them receiver is installed the solid recording device.
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is circuit theory diagrams of recording device.
This utility model comprises ear piece (1), tee T (2), conduit (3), chest piece (4), at the back of chest piece (4) electronic timer (7) is housed, side in chest piece (4), set up two single joint receivers (6), can be for 2-3 people auscultation simultaneously, available again one of them receiver connects solid recording device (5), at the stethoscope membranous part employing disposable sterilization thin film (9) of chest piece (4).
Electronic timer (7) is equipped with at stethoscopic chest piece (4) back, and the doctor of changing over draws sleeve and sees defective and the inconvenience of showing the auscultation counting and bringing opportunities for contamination.The digital display that the movement of electronic timer (7) utilizes market to sell shows the electronic watch repacking, also can replace watch function, three knobs (8) are arranged, one is the functional mapping knob, during demonstration, minute, second or year, month, day, the function in week, another is to transfer digital function, and the 3rd is light display digit knob, can bring into play peculiar effect in accident and field emergency.
Two single joint receivers (6) are set up in stethoscopic chest piece (4) side, and external two stethoscopes supply 2-3 people auscultation simultaneously and the consultation of doctors simultaneously.
This utility model adopts the disposable sterilization thin film at its membranous part, can prevent cross infection, and is particularly suitable during especially to lazaretto ward and dermatosis patient inspection, and adopts this thin film cold season, can play every the cold effect, more easy for patients to accept.
Two single joint receivers (6) are set up in stethoscopic chest piece (4) side, available one of them receiver connects solid recording device (5), this device volume is little, distortion is little, noise is little, tonequality is clear, can record patient typical case and significant medical history data, uses for the consultation of doctors and teaching.
Recording circuit adopts the extensive CMOS integrated circuit of QX series language processor, and it includes 8 D/A, A/D converter, microphone amplifier, integrated amplifier, wherein outside DRAM stochastic and dynamic memorizer, the S of connecting
1Be record button, effect is that the heart signal that will record plays back.In order to reduce the quiescent dissipation of circuit, two electrical switch V in circuit, have been designed
