Description
Technical field
This utility model relates to a kind of stethoscope.
Background technology
Stethoscope is the most frequently used diagnostic tool of inside and outside woman doctor, mainly comprises structures such as pick up, conduction portion, listening gear, and its conduction portion generally adopts the PVC material, and the auscultation effect that internal diameter is big more, length is short more, tube wall is thick more is good more.But there are a lot of problems in traditional stethoscope: auscultation depends on doctor's individual level, and individual level does not reach requirement, then occurs the situation of mistaken diagnosis possibly; Higher to outside environmental requirement, preferably can use, but usually have various interference in the reality at very quiet environment, during for example to child's auscultation, the child can send various sound, hands can be pullled conduction portion; Carry inconvenience, conduction portion is connected with other two parts, is difficult for placing.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned deficiency, a kind of novelty is provided, is easy to realize, is convenient to place, be not subject to the stethoscope of environmental disturbances.
A kind of stethoscope, comprise pick up and listening gear, in pick up, be provided with the audio collection module, the audio collection module comprises acoustic sensor, amplifier, wave filter, A/D converter and the central processing unit that connects successively, and central processing unit also is connected with emitter, display and memory module; Be provided with the receptor corresponding with emitter in the stethoscope, receptor is connected with acoustic transducer.Pass through radio communication between pick up and the pick up, realize the collection and the processing of audio frequency in the pick up, and with signal by radioing to listening gear, realize again that in listening gear electrical signal conversion is an acoustical signal, and in central processing unit, can also realize the storage of signal, the demonstration that display is realized signal.
Adopt Bluetooth communication between described emitter and the receptor, avoided infrared signal to be easy to problems such as interference.
Described display is a liquid crystal display, and the information that liquid crystal display shows in detail, accurately.
Stethoscope that this utility model provides adopts advanced technology such as wireless communication technology, audio signal processing technique, novel structure, is easy to realize that auscultation is effective, not disturbed by external environment condition, be easy to carry about with one and place, the auscultation result can store, and is convenient to subsequent query and uses.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
Wherein, 1, pick up, 2, listening gear, 3, acoustic sensor, 4, amplifier, 5, wave filter, 6, A/D converter, 7, central processing unit, 8, emitter, 9, memory module, 10, display, 11, receptor, 12, acoustic transducer.
The specific embodiment
Embodiment with indefiniteness further explains, illustrates the technical program below.
A kind of stethoscope, as shown in Figure 1, this stethoscope comprises two parts: pick up 1 and listening gear 2, be provided with the acoustic sensor 3, amplifier 4, wave filter 5, A/D converter 6 and the central processing unit 7 that connect successively in the pick up 1, central processing unit 7 also is connected with emitter 8, display 10 and memory module 9; Be provided with receptor 11 and the acoustic transducer 12 corresponding in the listening gear 2 with emitter 8; Pass through Bluetooth communication between emitter 8 and the receptor 11.
During application, the shell of pick up 1 and listening gear 2 can be set to various shape and size as required.Acoustic sensor 3 is collected sound signal at first, acoustical signal is converted to the signal of telecommunication and is transferred to amplifier 4 amplifications, realize analog digital conversion through being transferred to A/D converter after wave filter 5 filtering again, digital data transmission after the conversion is given central processing unit 7, central processing unit 7 is realized Signal Processing, signal is sent to receptor 11 by emitter 8, can realize storage by memory module 9, can also be by the demonstration of display 10 realizations to digital signal.Receptors 11 in the listening gear 2 are transferred to acoustic transducer 12 with this signal after receiving the signal that emitter 8 sends, and acoustic transducer 12 is reduced to acoustical signal with this signal, arrives doctor's ear by equipment such as earphones.Like this, the doctor can diagnose by 2 couples of patients of listening gear, and the signal contrast that can also show with display 10 is diagnosed more accurate.
Claims (3)
1. stethoscope, comprise pick up (1) and listening gear (2), it is characterized in that: in pick up (1), be provided with the audio collection module, the audio collection module comprise successively the acoustic sensor (3) that connects, amplifier (4), wave filter (5), A/D converter (6) and in come processor (7), central processing unit (7) also is connected with emitter (8), display (10) and memory module (9); Be provided with the receptor (11) corresponding with emitter (8) in the stethoscope (2), receptor (11) is connected with acoustic transducer (12).
