It is known to attach hand-grip openings with a lock in the walls of incubators, which consists essentially of a plastic tube, which at one end to a fixed ring on the incubator hood and the other end with a movable one Ring is connected. Both rings are arranged concentrically to one another and can be rotated against one another. By twisting the movable ring, one end of the plastic tube is turned against the other The end is twisted so far that the middle part of the hose is wound around itself, as a result of which a closure is achieved. This lock has the disadvantage that when the ring is turned the treating person when turning the ring and when reaching through the opening of the plastic tube can infect the hand, for example (Dräger-Prospectus P / GB 6141 -July 1965).

There are also closures for handle openings in the form of sliding windows known that be opened or closed by hand, which is also a risk of infection for the treating person Person exists. In addition, rails for sliding windows form dirt deposits.

Hand openings with »5 Swivel flaps known which are connected to the housing wall via a hinge, the Swivel flap moves away from the housing wall when it is opened. It should be further known in Hinge to provide a spring, while the flap on the other side by a lock is held. After unlocking the lock, the opening flap folds under the action the spring to the front. The arrangement of such a flap would have the disadvantage of Pumping action. In particular, when the flap is pressed together, room air containing germs could enter the interior of the medical device, such as in particular get into the interior of the incubator. A Another disadvantage is that the device is shaken by the swinging flap and that the forward flap interferes with the operation of the device.

The invention avoids the disadvantages of the known devices. The invention has the Task set, a closure flap that is as easy to use as possible for the operator to create, the operation of which does not involve any risk of infection and through which finally the Opening and closing no air is forced into the interior of the housing. The task is through solved the invention specified in claim 1.

The invention has the advantage that the closure flap can be opened once without use the hand, for example with the elbow, can be done. When opening the flap no air flow is achieved with respect to the interior of the housing. The flap can still can be closed very easily. Advantageous further developments of the invention are set out in the subclaims described.

Further details of the invention are based on the exemplary embodiment shown schematically in the drawing explained, namely shows

Fig. 1 is a side view of a side wall of an incubator hood,

Fig. 2 is a longitudinal section in the plane AA according to Fig. 1,

Fig. 3 a section in the plane BB according to Fig. 2,

A b b. 4 a section in the plane CC according to Fig. 1.

In the partially drawn side wall 1 of the incubator housing an opening la is let in, which is covered by a disc 2. This is hinged on the lever 3 on a joint 4, which with a journal 5 is provided. This is in one in the disc 1, for example with the help of Screws held bearing 6 stored. For this purpose, the bearing pin 5 is provided with a bearing washer 7, which is supported against the end faces of the bearing bore.

On the opposite side, the disk 2 is provided with a bolt 8 which engages under a latching hook 9. The latching hook can be attached to the housing 1 with the aid of a rubber strip 10, for example. The end face 9a of the hook is beveled so that the bolt 8 is guided into the locking position when the disk is closed. The disk 2 is also provided with a lateral projection 11 at one end.

By pressing lightly, for example with the elbow, on the plate part, the disc2 falls through

their own weight down and is the handle opening 1 α free. In order to prevent the disk 2 from swinging back and forth several times, a spring disk 12 is used for damping in the bearing 5, which brakes the movement of the disk.

By interposing the joint 4, the disk can also be moved in the direction of the housing wall 1 are pushed away, as is desired, for example, when cleaning.

The disk can be provided at its free end with a slide, such as a roller 13, which is shown in FIG the closure layer lies within a recess 14. When the disc swings down, will the disc is raised by the roller 13 running onto the housing wall 1 at a low height, so that scratching the disc 2 when sliding along the housing wall 1 is avoided.

If the pane 2 is to be lifted away from the housing wall 1 over a larger pivoting range when it is opened a slider 15, which is attached to the lever 3 and on the run-up surface, can be used for this purpose 16 of the run-up piece 17 runs up when the disc is pivoted and lifts the disc.

The handle opening can have a circular, have a square or rectangular cross-section.

Claims (8)

Patent claims: 1. Closure flap hinged to the housings of medical devices for hand access openings, in particular incubators, characterized in that the ^{: the} closing flap (2) is mounted on one side of the housing wall (1) so that it can pivot about an axis perpendicular to the opening flap (la) and is held in the closed position on its opposite side by an easily detachable catch (9). 2. Closure flap according to claim 1, characterized in that the catch (9) consists of one There is a hook-shaped component, with the interposition of a rubber strip (10) with the Housing wall (1) is connected and that on its end face (11) located in the opening direction a ramp surface for the closure part (8) attached to the flap is provided. 3. Closure flap according to claim 1 or 2, characterized in that the closure flap (2) with a laterally protruding pressure surface (11) that can be opened with the elbow is provided. 4. Closure flap according to one of claims 1 to 3, characterized in that the Closure flap (2) on the side of the closure with a, preferably in the form of a Roller formed slider (13) is provided, which when pivoting the closure flap (2) the in the housing wall (1) made recess (14) leaves and thus the closure flap (2) lifts off the housing wall (1). 5. Closure flap according to claim 4, characterized in that the recess (14) consists of a There is a groove in the housing wall (1), which in the closed position is arranged on the flap (2) Slider, such as roller (13) receives. 6. Closure flap according to one of claims 1 to 5, characterized in that the Closure flap (2) is provided with a slider (15) in the vicinity of its pivot axis (5), which runs onto a ramp surface (16) arranged on the housing wall (1) when it is opened, so that the flap is lifted from the housing wall (1). 7.
