Preferably, the adsorption orifice end outward flanging of described sucker, makes adsorption orifice part more wear-resisting, has avoided affecting because of the concentrated wear of sucker adsorption orifice the sealing of sucker, finally causes the gas leakage of sucker and makes sucker lose adsorption function.

Preferably, described sucker top layer is tin bronze alloys layer, tin bronze alloys possesses good mechanical performance, be conducive to the manufacture of sucker, and wearability is strong, effectively guarantees the service life of sucker, and guaranteed the wearability of sucker adsorption orifice, avoid causing due to the wearing and tearing of adsorption orifice the gas leakage situation of sucker, guaranteed the sealing of sucker.

Further, described air bag is all located at the side with respect to auscultation face on auscultation head, and at auscultation probe medium position mutually immediately, therefore can, so that staff is pressed each air bag at the medium position of auscultation head simultaneously, make each sucker enter negative pressure state simultaneously and be adsorbed on human body surface.

Preferably, described air bag is greater than the volume of remainder near the volume at auscultation head middle part, therefore, by pressing medium position, just can push more airbag gas and discharge sucker, strengthens the negative pressure of sucker, has directly strengthened the adsorption effect of sucker.

Alternatively, described air bag is bar-shaped, and its volume reduces gradually from auscultation head central authorities to auscultation head peripheral direction, facilitate further staff at auscultation head middle part by pressuring gasbag, and strengthen sucker adsorption effect.

Preferably, described air bag is made up of silastic-layer, and silicone rubber has good sealing, and elastic performance is superior, makes air bag possess good resilience.

Alternatively, described each air bag is arranged with a cover body outward, and the periphery of described cover body is connected on auscultation head, by manual squeezing cover body, just can push easily each air bag simultaneously.

Compared with prior art, the beneficial effects of the utility model are: by the adsorption orifice of sucker and the auscultation face place of auscultation head at grade, several suckers are all communicated with separately independently air bag, in the time of each air bag of extruding, can make formation negative pressure in sucker and be adsorbed on human body surface, and can be adsorbed on human body surface by related auscultation head; In addition, because sucker is several and arranges independently of each other, therefore each adsorption orifice can be adsorbed on human body surface at multiple diverse locations, has effectively avoided, because the situations such as single sucker gas leakage or absorption shakiness cause adsorption function to lose efficacy, therefore having realized good adsorption effect.
