Description

Comfortable type stethoscope

Technical field

This utility model relates to a kind of comfortable type stethoscope, belongs to medical instruments field.

Background technology

Stethoscope is a kind of medical instrument, be used for listening to the sound in human body or animal body, such as heart, breathing, the intestines and stomach etc., stethoscope is cup type (bell), can pickup scope be all audible sound frequencies, and membrane type can has a skim, low-frequency sound frequency being less than 200Hz filters out, and makes it more responsive to high frequency sound equipment.Because auscultation head is metal material, easily stimulating human body when pressing close to patient skin, causing discomfort.In addition, in order to isolated external noise, allow doctor listen clearer simultaneously, stethoscope earpiece part is all that hard material is made, and then provides elastic force by metal spring leaf, is clipped in ear, but this metal spring leaf elastic force is comparatively large, after wearing slightly for a long time, easily ear folder pain.

Utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of comfortable wearing, can not stimulate the comfortable type stethoscope of patient skin simultaneously.

Comfortable type stethoscope described in the utility model, comprise auscultation head and receiver, auscultation head is connected by sound guide tube with receiver, sealing air in pipeline, auscultation head wraps up one deck tinfoil, tinfoil surface coverage one deck gauze, through hole is set in the position of the filtered audio film of auscultation head and exposes filtered audio film, receiver overlaps rubber sleeve, and turn up in rubber sleeve end, screw thread established by receiver, attaching nut on screw thread, receiver also overlaps limited location plate, establishes spring between limiting plate and nut, two receivers are fixedly connected with by metal spring leaf.

Operation principle and process:

During work, wear this stethoscope in the usual way, due to receiver overlapping rubber sleeve, turn up in rubber sleeve end, when receiver is against in auditory meatus, rubber sleeve is more soft, rubber sleeve and auditory meatus Long contact time can not cause discomfort, according to the distance between individual use habit adjusting nut and limiting plate, to regulate the elasticity of limiting plate, limiting plate is against on ear, because metal spring leaf elasticity is larger, can play certain cushioning effect by spring, limiting plate also has sound insulation simultaneously, prevents the effect that external sound disturbs.Auscultation head is placed on patient part auscultation, gauze can prevent the metal shell of auscultation head from directly contacting and chafe with patient skin, after auscultation, if need auscultation another one patient, tinfoil is torn, again wrap up the new tinfoil of one deck, clean hygiene, prevents cross infection.

The beneficial effect that this utility model is compared with prior art had is:

Comfortable type stethoscope described in the utility model, rubber sleeve is more soft, rubber sleeve and auditory meatus Long contact time can not cause discomfort, certain cushioning effect can be played by spring, limiting plate also has sound insulation simultaneously, prevent the effect that external sound disturbs, gauze can prevent the metal shell of auscultation head from directly contacting and chafe with patient skin, if need auscultation another one patient, tinfoil is torn, again wrap up the new tinfoil of one deck, clean hygiene, prevent cross infection, simple and practical, comfortable wearing.

Accompanying drawing explanation

Fig. 1 is this utility model embodiment schematic diagram;

Fig. 2 is part A partial enlarged drawing embodiment illustrated in fig. 1.

In figure: 1, sound guide tube; 2, metal spring leaf; 3, stannum paper; 4, auscultation head; 5, gauze; 6, limiting plate; 7, rubber sleeve; 8, nut; 9, spring.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

As depicted in figs. 1 and 2, comfortable type stethoscope described in the utility model, comprise auscultation head 4 and receiver, auscultation head 4 is connected by sound guide tube 1 with receiver, sealing air in pipeline, auscultation head 4 wraps up one deck tinfoil 3, tinfoil 3 surface coverage one deck gauze 5, through hole is set in the position of the filtered audio film of auscultation head 4 and exposes filtered audio film, receiver overlaps rubber sleeve 7, turn up in rubber sleeve 7 end, screw thread established by receiver, attaching nut 8 on screw thread, receiver also overlaps limited location plate 6, spring 9 is established between limiting plate 6 and nut 8, two receivers are fixedly connected with by metal spring leaf 2.

Operation principle and process:

During work, wear this stethoscope in the usual way, owing to receiver overlapping rubber sleeve 7, turn up in rubber sleeve 7 end, when receiver is against in auditory meatus, rubber sleeve 7 is more soft, rubber sleeve 7 and auditory meatus Long contact time can not cause discomfort, according to the distance between individual use habit adjusting nut 8 and limiting plate 6, to regulate the elasticity of limiting plate 6, limiting plate 6 is against on ear, because metal spring leaf 2 elasticity is larger, can play certain cushioning effect by spring 9, limiting plate 6 also has sound insulation simultaneously, prevents the effect that external sound disturbs.Auscultation head 4 is placed on patient part auscultation, gauze 5 can prevent the metal shell of auscultation head 4 from directly contacting and chafe with patient skin, after auscultation, if need auscultation another one patient, tinfoil 3 is torn, again wrap up the new tinfoil 3 of one deck, clean hygiene, prevents cross infection.
