Abstract
Abstract An incubator has a transparent covering hood having at least one side wall on which two flaps are mounted for closing access openings formed in the side wall. The flaps are each provided with a hinge and closure element. The flaps and access openings are so configured that the maximum possible freedom of movement is provided for the person treating the patient while at the same time the smallest possible outlet area is attained to prevent heat and oxygen losses from within the incubator to the ambient. For this purpose, the access openings are configured to be elongated and so that their respective longitudinal axes conjointly define an upwardly facing obtuse angle. To improve visibility for observing the premature infant and to improve ergonomically correct actuation of the operating elements, both the hinge and the closure element are located together on one side of the flap.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
171 words
An incubator comprising: a base; a transparent hood mounted on said base and having a side wall; said side wall defining a horizontal axis extending parallel to said base and said side wall having two access openings forming therein; each of said access openings having a longitudinal axis defining an acute angle with said horizontal axis and being elongated along said axis thereof, said openings being unsymmetrical with respect to the longitudinal axis corresponding thereto and being disposed in said side wall so as to cause said axes to intersect at a point to conjointly define an obtuse angle opening upwardly; two flaps corresponding to respective ones of said access openings; hinge means for pivotally mounting each of said flaps to said side wall so as to enable the flap to pivot between a first position whereat the flap covers and closes off the access opening and a second position whereat the flap is away from said opening; and, latching means for latching each of said flaps in the first position.
Claim 2
Dependent Claim
171 words
An incubator comprising: a base; a transparent hood mounted on said base and having a side wall; said side wall defining a horizontal axis extending parallel to said base and said side wall having two access openings forming therein; each of said access openings having a longitudinal axis defining an acute angle with said horizontal axis and being elongated along said axis thereof, said openings being unsymmetrical with respect to the longitudinal axis corresponding thereto and being disposed in said side wall so as to cause said axes to intersect at a point to conjointly define an obtuse angle opening upwardly; two flaps corresponding to respective ones of said access openings; hinge means for pivotally mounting each of said flaps to said side wall so as to enable the flap to pivot between a first position whereat the flap covers and closes off the access opening and a second position whereat the flap is away from said opening; and, latching means for latching each of said flaps in the first position.
Claim 3
Dependent Claim
186 words
An incubator comprising: a horizontally extending base; a transparent hood mounted on said base and having a side wall; said side wall having two access openings formed therein, each of said access openings having a longitudinal axis and being elongated along said axis thereof, said openings being disposed in said side wall so as to cause said axes to intersect at a point to conjointly define an obtuse angle opening upwardly; each of said elongated access openings being a triangular opening having a base and rounded corners, and each of said access openings being positioned in said side wall so that said base of said triangular opening lies substantially parallel to said base of said incubator; two flaps corresponding to respective ones of said access openings; hinge means for pivotally mounting each of said flaps to said side wall so as to enable the flap to pivot between a first position whereat the flap covers and closes off the access opening and a second position whereat the flap is away from said opening; and, latching means for latching each of said flaps in the first position.
Claim 4
Dependent Claim
186 words
An incubator comprising: a horizontally extending base; a transparent hood mounted on said base and having a side wall; said side wall having two access openings formed therein, each of said access openings having a longitudinal axis and being elongated along said axis thereof, said openings being disposed in said side wall so as to cause said axes to intersect at a point to conjointly define an obtuse angle opening upwardly; each of said elongated access openings being a triangular opening having a base and rounded corners, and each of said access openings being positioned in said side wall so that said base of said triangular opening lies substantially parallel to said base of said incubator; two flaps corresponding to respective ones of said access openings; hinge means for pivotally mounting each of said flaps to said side wall so as to enable the flap to pivot between a first position whereat the flap covers and closes off the access opening and a second position whereat the flap is away from said opening; and, latching means for latching each of said flaps in the first position.
Claim 5
Dependent Claim
67 words
The incubator of claim 2, said hinge means and said latching means being mounted on the same side of the flap; said flaps having respective side edges remote from the point of intersection of said axes; and said hinge means and said latch means being mounted at said side edges thereby providing a clear view to the inside of the incubator in the region between said flaps.
Claim 6
Dependent Claim
49 words
The incubator of claim 3, said hinge means of each flap including bracket means defining a pivot axis disposed with respect to said side wall so as to cause the flap to pivot outwardly to said second position under the force of gravity when said latching means is released.
Claim 7
Dependent Claim
44 words
The incubator of claim 4, said side wall having vertical lateral side edges and said brackets defining said pivot axis so as to be inclined away from said side wall and toward the closest one of said side edges in the upwardly extending direction.
