Abstract
Abstract The invention relates to a method of manufacturing an otoscope, according to which method the component parts of the otoscope can be assembled with particular ease. In order to achieve this, a prefabricated fiber optics assembly is employed, and the otoscope is configured such that all the parts can be inserted in sequence from one side of the housing head into an accommodation opening of the housing head.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
A method of manufacturing an otoscope having a housing head provided with fiber optics assembly and loupe, the housing head being attached to a battery-holding grip member; the method comprising attaching the housing head, provided with an opening extending there-through to the battery-holding, grip, providing a prefabricated fiber optics assembly of funnel means and a fiber optics bundle associated therewith, inserting the assembly into the opening passing through the housing head, fixing the assembly in place therein, and attacing the loupe to the housing head, wherein prior to inserting the prefabricated fiber optics assembly into the housing head, a funnel ejector is assembled with the fiber optics assembly, and both parts are then inserted into the housing head together.
Claim 2
Independent Claim
119 words
A method of manufacturing an otoscope having a housing head provided with fiber optics assembly and loupe, the housing head being attached to a battery-holding grip member; the method comprising attaching the housing head, provided with an opening extending there-through to the battery-holding, grip, providing a prefabricated fiber optics assembly of funnel means and a fiber optics bundle associated therewith, inserting the assembly into the opening passing through the housing head, fixing the assembly in place therein, and attacing the loupe to the housing head, wherein prior to inserting the prefabricated fiber optics assembly into the housing head, a funnel ejector is assembled with the fiber optics assembly, and both parts are then inserted into the housing head together.
Claim 3
Dependent Claim
28 words
The invention according to claim 1 wherein the prefabricated fiber optics assembly is introduced into the opening passing through the housing head from the rear of the head.
Claim 4
Dependent Claim
24 words
The invention according to claim 1 wherein the prefabricated fiber optics assembly when introduced into the housing head is engaged against a stop member.
Claim 5
Dependent Claim
23 words
The invention according to claim 3 wherein the prefabricated fiber optics assembly is fixed in the housing head by means of a cover.
Claim 6
Dependent Claim
17 words
A method according to claim 4 wherein the cover is attached to housing head by screw means.
Claim 7
Dependent Claim
27 words
The invention according to claim 5 wherein the loupe is also attached to the housing head by the screw means which forms a pivot for the loupe.
Claim 8
Dependent Claim
55 words
The invention according to claim 4 wherein, after insertion the fiber optics assembly but prior to the attachment of the cover springs and spherical catches are introduced into axial blind holes of the housing head for holding the cover in position, which catches extend through openings in the cover into catch recesses in the loupe.
Claim 9
Dependent Claim
46 words
The invention according to claim 2 wherein a set screw is screwed in from the opening in the housing head which accommodates the cover, said set screw serving to attach the housing head to the battery-holdng grip, prior to the insertion of the fiber optics assembly.
Claim 10
Dependent Claim
11 words
An otoscope manufactured by a method as claimed in claim 1.
