Abstract
The utility model discloses a portable headset type stethoscope, which consists of a stethoscope detection head 1 and a sound guide hose 2, the sound guide hose 2 is an integral Y-shaped rubber tube, the lower end is inserted with the stethoscope detection head 1, the two ends at the upper end are inserted with listening ear covers 3, and the outer sides of the listening ear covers 3 are provided with ear caps 4. The listening ear covers of the portable headset type stethoscope are worn at the outer sides of the ears, which can not generate the pressure to the external acoustic meatus and not damnify the external acoustic meatus; furthermore, as the sound guide hose is completely made of rubber, the folding is easy, the carry is convenient, the structure is simple, the production cost is low and the utility model can not affect the hearing at the same time.
Description
Technical field: this utility model relates to stethoscopic improvement, specifically a kind of portable earphone-type stethoscope.
Background technology: stethoscope be the medical worker have a medical check-up, main utensil when diagnosing the state of an illness, mainly detect heartbeat number of times, unusual number of times, frequency, breathing, borborygmus etc., thus the diagnosis state of an illness.The stethoscope that uses is made of two earplugs, stethoscope detection head, leading note flexible pipe, two leading note hard tubes, spring leafs mostly at present, the stethoscope detection head is made of box body and vibrating diaphragm, earplug is enclosed within leading note hard tube end, and the detected vibration signal of vibrating diaphragm passes in ear by leading note flexible pipe, leading note hard tube, earplug.This stethoscopic shortcoming is: two earplugs directly are pressed on two external auditory meatuss of medical worker, cause external auditory meatus and stethoscope internal pressure to raise, and influence the auscultation effect; Because earplug is little and hard, and is bigger in ear pressure, the long-time extension is pressed on the external auditory meatus, makes the external auditory meatus soft tissue be subjected to certain damage, caused pain with the person; In addition, because of two ears all stop up, the influence person of using audition.Simultaneously,, be difficult for folding, be not easy to carry and go out to use because the earplug hypomere is leading note hard tube and spring leaf.
Summary of the invention: the technical problem that this utility model solved is: providing a kind of does not have pressure, can not cause damage medical worker's external auditory meatus, easily folding, easy to carry again simultaneously portable earphone-type stethoscope.
For realizing above purpose, the technical scheme that this utility model is taked is: this portable earphone-type stethoscope, constitute by stethoscope detection head, leading note flexible pipe, the leading note flexible pipe is an integral body " Y " shape rubber tube, lower end is pegged graft and is gone up the stethoscope detection head, all pegging graft to go up and listen earmuff in two terminations, upper end, listens the earmuff outside to establish the ear lid.It is circular listening earmuff, makes of rubber, and the center is a cavity, opening to the inside, opening diameter 3-6cm listens earmuff to be worn over the ear outside, and the ear lid is fixed on turning cylinder listens upper edge, the earmuff outside, when needs are talked with the patient, rotatable ear lid, directly obedient, be provided with the leading note plate in the cavity, so that the volume of preaching in the leading note flexible pipe is reduced the loss, listen between the earmuff for two to connect with spring card.
The beneficial effects of the utility model are: compare with the stethoscope of present application, listen earmuff to be worn over the ear outside, good seal, can improve the auscultation effect, external auditory meatus is not produced pressure, no longer damage external auditory meatus, and, makes the leading note flexible pipe because of being rubber entirely, fold easily, be convenient for carrying and simple in structure, cost of manufacture is low, does not influence audition simultaneously.
Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 looks sketch map for this utility model structure master.
Fig. 2 listens earmuff along the A-A cross-sectional schematic for this utility model.
Make this utility model with reference to accompanying drawing 1,2.This portable earphone-type stethoscope is made of stethoscope detection head 1, leading note flexible pipe 2, and leading note flexible pipe 2 is an integral body " Y " shape rubber tube, and lower end is pegged graft and gone up stethoscope detection head 1, and all pegging graft to go up and listen earmuff 3 in two terminations, upper end, listens earmuff 3 outsides to be provided with ear lid 4.It is circular listening earmuff 3, makes of rubber, and the center is a cavity, opening to the inside, opening diameter 3-6cm can be buckled in the ear outside, ear lid 4 usefulness turning cylinders are fixed on the upper edge, the outside of listening earmuff 3, are provided with 5, two of leading note plates in the cavity and listen between the earmuff 3 with spring card 6 connections.
