[0005] Medical device with display

[0006] The invention relates to a medical device comprising a housing and at least one display.

[0007] Conventional medical devices, such as ventilators, defibrillators, patient monitors or suction pumps, have at least one display located in or on the device housing, depending on the device and its features.

[0008] The display can be used, for example, to show settings of the medical device and / or vital parameters of a patient and / or other sensor-acquired measurements and / or instructions for a user.

[0009] During the operation of the medical device, it is of great importance for the device user, for example a paramedic in a rescue operation, to always be able to read the display of the medical device clearly in order to use the displayed information accordingly and to be able to carry out the treatment of a patient in a data-oriented manner.

[0010] The display of medical devices is in most cases located on a side wall of the housing, usually the front wall, as this ensures that the display is generally readable in various operating positions. KLICKOW & WETZEL

[0011] Mobile medical devices are frequently used in rescue operations, both outside the ambulance and inside the ambulance during patient transport.

[0012] In ambulances, medical devices are often placed in brackets, mostly wall mounts, to ensure they are securely fixed, space-saving, and easily accessible. This results in an initial operating position where, due to its relatively high position relative to the floor, a device display can usually be read directly from the front.

[0013] Outside the ambulance, for example when treating a patient lying on the floor, the medical devices used are usually placed on the floor. In this lower, secondary operating position, the device display typically has to be read at an angle from above.

[0014] Depending on the display, this can lead to problems with readability due to reflections on the surface and / or a narrow viewing angle of the display, i.e., the angle range in which the display is easily readable.

[0015] Most well-known medical devices have a housing that is essentially cuboid in shape. The display is located on a side wall of the housing, usually the front wall, which is oriented perpendicular to the base of the device. The rear wall of the medical device is parallel to the front wall, and the angles between the front wall and the base, as well as the top of the housing, are 90°.

[0016] Since the medical device is usually positioned with its back panel against a wall, for example a vehicle wall or wall mount, the parallel design of the back panel and front panel achieves the desired orientation of the display in this usage position.

[0017] Adjusting the display angle for improved readability in various usage positions of the medical device is achieved, according to current technology, via adjustable brackets and / or complex carrying devices. However, these are expensive and / or not particularly robust. KLICKOW & WETZEL

[0018] It is therefore an object of the invention to provide an improved medical device with at least one display that solves at least some of the problems mentioned.

[0019] This problem is solved according to the invention by a medical device according to claim 1.

[0020] The dependent patent claims describe advantageous aspects of the invention.

[0021] The features of a medical device disclosed below are, in all feasible combinations, part of the invention.

[0022] A medical device according to the invention comprises a housing and at least one display. At least one display is arranged on a side wall of the housing, in particular on the front wall. The housing of the medical device further comprises a base and a rear wall.

[0023] The side wall of the housing has a side wall element in which the display is arranged. Accordingly, the invention also includes embodiments with a subdivided side wall of the housing that supports the display. The side wall element can be a purely conceptually separate part of the side wall, thus structurally indistinguishable from the rest of the side wall, or it can be a part that is structurally distinguishable from the rest of the side wall.

[0024] According to the invention, at least the side wall element supporting the display is arranged at an angle α of less than 90° to the bottom of the housing.

[0025] This results in an inclined orientation of the display when the medical device is in a usage position where it stands on the base of the housing, making it easier to read from a viewing angle obliquely from above.

[0026] In the case of a divided side wall of the housing, it is sufficient if the side wall element supporting the display is arranged at an angle α of less than 90° to the base of the housing. This also includes embodiments of the invention in which parts of the side wall have a different angle to the base of the housing. KLICKOW & WETZEL

[0027] Preferably, the side wall element extends to the top of the housing in order to avoid any housing parts that may protrude over the display and restrict the view of the display.

[0028] In preferred embodiments of the invention, at least the side wall element supporting the display is arranged at an angle a less than or equal to 85° to the bottom of the housing.

[0029] In preferred embodiments of the invention, at least the side wall element supporting the display is arranged at an angle a less than or equal to 80° to the bottom of the housing.

[0030] In particularly preferred embodiments of the invention, at least the side wall element supporting the display is arranged at an angle α less than 90° and greater than or equal to 50° to the bottom of the housing.

[0031] In a particularly preferred embodiment of the invention, at least the side wall element supporting the display is arranged at an angle a less than or equal to 80° and greater than or equal to 60° to the bottom of the housing.

[0032] In embodiments of the invention, at least between the side wall element supporting the display or the entire side wall supporting the display and the bottom of the housing, an angle a of less than 90° is realized, wherein x = 90° - a and wherein the angle between the rear wall and the bottom is 90° + x and the angles between the rear wall and the top of the housing and at least the side wall element supporting the display or the entire side wall supporting the display are 90°.

[0033] In embodiments of the invention, the side wall supporting the display is designed as the front wall of the housing.

[0034] In embodiments of the invention, the rear wall of the housing is aligned approximately parallel at least to the side wall element of the side wall supporting the display or to the entire side wall.

[0035] The arrangement of the housing walls according to the invention provides two different orientations of the display for at least two different KLICKOW & WETZEL through the housing shape itself.

[0036] The inventive solution provides various operating positions for the medical device. It is extremely robust and requires no moving parts for adjusting the device's orientation. This eliminates the need for expensive and / or only partially robust adjustable holding or carrying devices to improve display readability in the most common operating positions.

[0037] Furthermore, the weight to be transported in mobile applications can be reduced by eliminating the need for adjustable carrying devices.

[0038] The invention also includes embodiments in which the front and rear walls are not aligned parallel to each other. For example, embodiments are conceivable in which the rear wall of the housing is inclined further outwards from the base body at its upper end, thus enabling improved readability of the display from a viewing angle obliquely from below when used in a wall mount.

[0039] In some of these embodiments of the invention, the internal angle of the housing between the back wall and the top, opposite angle a, is also less than 90°.

[0040] In preferred embodiments, the medical device is designed such that the selected beveling of the housing side supporting the display, in conjunction with the ratio between the depth and height of the medical device and a low center of gravity, results in a similar stability to a cuboid-shaped medical device.

[0041] In the corresponding embodiments of the invention, the ratio of depth to height of the medical device is chosen to be between 1:1.1 and 1:1.2 so that the medical device does not tip backwards too easily.

[0042] In embodiments of the invention, the area of ​​the side wall supporting the display is larger than the area of ​​the back wall.

[0043] This provides more space on the front of the medical device for arranging at least one display and control elements.

[0044] A medical device according to the invention is, for example, designed as a ventilator, a defibrillator, a patient monitor, or a suction pump. KLICKOW & WETZEL

[0045] In embodiments of the invention, it is not limited to medical devices, but generally includes devices with a housing and at least one display arranged in or on the housing.

[0046] The figures below illustrate an exemplary embodiment of the invention. They show:

[0047] Figure 1: A perspective view of a medical device according to the invention with a display in a wall mount,

[0048] Figure 2: A side view of the medical device according to Figure 1 ,

[0049] Figure 3: A representation of the viewing angle of a user of the medical device in a wall mount according to Figures 1 and 2,

[0050] Figure 4: A perspective view of a medical device according to the invention with a display on the floor,

[0051] Figure 5: A representation of the viewing angle of a user of the medical device on the floor according to Figure 4 and

[0052] Figure 6: A schematic representation of a cross-section of a medical device according to the invention.

[0053] Figures 1 and 2 show an embodiment of a medical device (1) according to the invention in a wall mount.

[0054] The housing (2) of the medical device (1) has a side wall (4), a base (7), a rear wall (6), and a top (8). Furthermore, the medical device (1) has a display (3) which is arranged on the side wall (4). The side wall (4) supporting the display (3) is here designed as the front wall of the housing (2).

[0055] In addition to the display (3), operating elements (9) are arranged on the front panel of the housing (2). KLICKOW & WETZEL

[0056] Since the front wall has a larger area than the rear wall (6), there is more space for the arrangement of the display (3), operating elements (9) and possibly other output elements, interfaces, labels, etc. compared to conventional housing designs.

[0057] The rear wall (6) of the housing (2) rests against a vertical wall (20). Since the rear wall (6) is parallel to the front wall, the display (3) is also vertically oriented.

[0058] Figure 3 shows the viewing angle (10) of a user (30) of the medical device (1) in a wall mount according to Figures 1 and 2. It can be seen that comfortable reading of the display (3) is possible in this first usage position.

[0059] Figure 4 shows the medical device (1) according to the embodiment shown in Figures 1 to 3 in a second position of use, namely with the base (7) of the housing (2) standing on the floor (21).

[0060] Due to the arrangement according to the invention of the side wall (4) supporting the display (3) and the base (7) of the medical device (1) at an angle of less than 90° to each other, the display (3) is inclined obliquely backwards.

[0061] Figure 5 illustrates the viewing angle (10) of a user (30) standing upright while viewing the medical device (2) standing on the floor (21). It can be seen that the display (3) is also easily readable in this second position of use.

[0062] Figure 6 shows a schematic representation of a cross-section of a medical device (1) according to the invention.

[0063] The side wall (4) supporting the display (3) is aligned parallel to the rear wall (6). The top (8) of the housing (2) is aligned perpendicular to the side wall (4) and the rear wall (6).

[0064] The internal angle α between the front wall and the floor (7) is less than 90°. In the illustrated embodiment of the invention, the internal angle α is approximately 70°. This value for the internal angle α is particularly advantageous for the readability of the display (3), independent of the other features of the illustrated embodiment. KLICKOW & WETZEL

[0065] The front wall is higher than the back wall (7), so that, with the same width of front wall and back wall (6), the front wall has a larger area than the back wall (6).
