Otoscope with ejectable ear speculum

摘要

The otoscope includes a mounting device (14) in which an ear speculum (16) is releasably attached, the ear speculum (16) including a conically tapering cone portion (20). The ear speculum (16) includes a substantially cylindrical base portion (24) being coaxial to the cone portion (20) and having a diameter which is larger than the largest diameter of the cone portion (20) and being connected through an intermediate wall portion (22) to the cone portion (20). At least one cutout (40) extending to the free edge of the base portion (24) is formed in the base portion (24) of the ear speculum (16). A resilient snap hook (26) is arranged in the cutout (40), the resilient snap hook (26) comprising a connecting leg (60), one end of which is connected to the base portion (24) in the proximity of the free edge and which substantially extends in circumferential direction of the base portion (24), and a holding leg (64) extending from the other end of the connecting leg (60) in the direction of the intermediate wall portion (22), wherein the inner side of the snap hook (26) protrudes into the cylinder space of the base portion (24).

主权项

1. An otoscope comprising a mounting device in which an ear speculum is releasably attached, said ear speculum including a conically tapering cone portion,wherein
said ear speculum comprises a substantially cylindrical base portion being coaxial to said cone portion and having a diameter which is larger than the largest diameter of said cone portion and being connected through an intermediate wall portion to said cone portion; at least one cutout extending to a free edge of said base portion is formed in said base portion of said ear speculum; a resilient snap hook is arranged in said at least one cutout, said resilient snap hook comprising a connecting leg having a first and a second end, said first end being connected to said base portion in proximity of said free edge, said connecting leg substantially extending in circumferential direction of said base portion, and a holding leg extending from said second end of said connecting leg towards said intermediate wall portion, wherein an inner side of said snap hook protrudes into a cylinder space of said base portion; and said mounting device comprises an outer collar arranged within said base portion, against which said intermediate wall portion abuts and in which at least one marginal recess is formed through which said snap hook is passed with the inner side under resilient deformation such that after resilient reforming said snap hook engages behind said outer collar next to said marginal recess.
