[0003] Medical system with mobile medical device and digital video camera for route monitoring

[0004] Technical field

[0005] The present invention relates to a medical system comprising at least one medical device that is mobile within a clinic, for example, on wheels. In particular, the invention relates to blood treatment machines for extracorporeal blood therapy.

[0006] background

[0007] Medical devices such as blood treatment machines for extracorporeal blood therapy, particularly hemodialysis machines, hemofiltration machines, hemodiafiltration machines, acute dialysis machines, emergency dialysis machines, and CKRT machines (formerly also known as CRRT machines), typically have a body, for example, in the form of a housing, a support structure, or a column. This body is often mounted on a chassis with casters and / or wheels for moving the medical device across a floor surface. Such medical devices usually have a screen, typically located on, attached to, or even above the body, which can result in the medical device being as tall and wide as, or even wider than, a fully grown adult.When such medical devices need to be moved within a clinic, for example from one room to another, this is usually done by a person pushing the device on its chassis to its new location. Due to the height and width of the medical device, the person pushing it has a limited field of vision in the direction of travel, meaning that the area in front of the device is only partially visible or not visible at all. An example of such a medical device is the multiFiltratePRO acute dialysis machine from the applicant, Fresenius Medical Care Deutschland GmbH, which has a height of approximately 167 cm, a width of approximately 65 cm, and a depth of approximately 69 cm.

[0008] This can lead to collisions with obstacles when pushing the medical device, resulting in costly damage or even destruction of both the device and the obstacle. This method of moving the medical device is particularly prone to accidents if the person pushing is shorter or significantly shorter than the device, as the device then obstructs the space in the direction of travel, either substantially or completely. Examples of potentially relevant obstacles in the space include door frames or jambs, thresholds, staircases, furniture, hospital beds, other medical equipment, fire extinguishers on walls, exposed electrical cables, and other people.The risk of a dangerous situation is particularly exacerbated when the medical device has to be moved under high time pressure, for example when an emergency medical device in an intensive care unit of a hospital has to be moved as quickly as possible from one room to a newly admitted emergency patient in another room and put into operation there as quickly as possible.

[0009] Summary of the invention

[0010] One object of the present invention is to reduce or even avoid the risk of an accident or the risk of a collision with obstacles when moving a medical device by pushing it on a floor surface.

[0011] Another object of the present invention is to ensure that, when moving a medical device by pushing it on a floor surface, the pushing person's field of vision into the object space in the direction of movement is maintained, even though the medical device obscures the field of vision.

[0012] A further object of the present invention is to ensure, with minimal additional manufacturing costs of the medical device or minimal additional costs of the medical system, that the field of vision of the person pushing a medical device into the object space in the direction of movement is maintained when moving a medical device by pushing it on a floor surface, even though the medical device obscures the field of vision.

[0013] Another object of the present invention is to enable a particularly rapid movement of a medical device by pushing it on a floor surface while simultaneously reducing the risk of collision with obstacles.

[0014] A further object of the present invention is to reduce or even avoid the costs of repair or replacement in the event of damage to the medical device that may occur when moving the medical device by pushing it across a floor surface due to collisions with obstacles. A further object of the present invention is to enable even shorter persons to move a medical device safely by pushing it across a floor surface, even when the medical device obstructs their field of vision in the direction of movement.

[0015] The present invention relates to a medical system having the features of claims 1 to 19.

[0016] The problems are solved according to the invention with the features of independent claim 1. Advantageous embodiments are the subject of the dependent claims.

[0017] The medical technology system according to the invention comprises at least one medical device configured to be moved by a person pushing it along a floor surface in a direction of movement, wherein the medical device has at least:

[0018] - a housing and / or a support structure and / or a column, wherein the housing and / or the support structure and / or the column is arranged on a chassis and / or connected to a chassis or has a chassis, wherein the chassis has rollers and / or wheels for the intended placement and / or movement of the medical device on the floor surface,

[0019] - a control and regulating device

[0020] - a screen and / or monitor in signal connection with the control and regulating device, wherein the screen and / or monitor is arranged on or at the housing and / or the supporting structure and / or the column, wherein the medical device system has at least one digital video camera which is fixedly or detachably arranged on the medical device, wherein the medical device system according to the invention is further characterized in that the at least one digital video camera is configured and arranged to generate a video data stream of a predetermined field of view, wherein the field of view comprises at least a part of the object space extending in the direction of movement.In other words, the digital video camera is configured and positioned to film an area of ​​object space that is located behind the medical device from the perspective of the person pushing the medical device, thus at least partially obscuring this area of ​​object space from the medical device and making it only partially or not at all visible to the person.

[0021] In some embodiments of the invention, the digital video camera is independent of the medical device. Such embodiments are characterized in that the at least one digital video camera is not in signal communication with the control and regulating device and / or the screen and / or the monitor of the medical device, or in other words, is not part of the medical device.

[0022] An advantage of such embodiments of the invention, in which the digital video camera is not in signal communication with the control and regulating device and / or the screen and / or the monitor of the medical device, is that no modifications need to be made to the software and / or hardware of an existing medical device. Therefore, such embodiments of the invention can be easily and cost-effectively retrofitted to existing medical devices.

[0023] In some embodiments of the invention, the digital video camera is independent of the medical device, and the medical system is further characterized in that the at least one digital video camera has an integrated screen and is configured by software and / or hardware modules for recording, processing, and playing back the video data stream in real time on the integrated screen of the at least one digital video camera, and that the at least one digital video camera is detachably attached to the medical device for intended use by means of a holding device, wherein the holding device aligns the at least one digital video camera with the object space extending in the direction of movement, and the integrated screen of the at least one digital video camera is oriented so that it is visible to the person pushing the medical device.

[0024] In other words, if needed, a digital video camera already present in the clinic can be detachably attached to the medical device using a mounting bracket. This bracket can be a quick-release device, a clip, a clamp, or something similar, which is attached to the medical device temporarily or permanently and is configured to hold the digital video camera.

[0025] In the present invention, the digital video camera is not configured and / or designed to perform remote directional and zoom control. In other words, in the present invention, the digital video camera is not configured to remotely define or change its field of view. Specifically, in the present invention, the digital video camera is not a so-called pan-tilt-zoom camera, which enables remote directional and zoom control.

[0026] In the present invention, the digital video camera is not configured and / or designed to be connected to or be connected to and / or interact with a server, in particular not with a media server and / or a management server.

[0027] In the present invention, the digital video camera is not configured and / or designed to transmit a video data stream to a server.

[0028] In the present invention, the digital video camera is not configured and / or arranged to monitor a patient and / or is not configured to transmit data to a patient monitoring center.

[0029] In the present invention, the digital video camera is not arranged and / or aligned and / or adjustable in such a way that the digital video camera can film the user when the user is in an area in front of the screen of the monitor, so that the user can view images on the monitor from this area.

[0030] In the present disclosure, real-time is understood to mean an operation in which program modules for processing the incoming video data stream are constantly ready for operation, so that the results of the processing are available and displayed on the screen within a specified time period, in particular in the range of less than 100 milliseconds, especially preferably less than 10 milliseconds, so that the viewer hardly notices the slight time delay compared to his perception of reality.

[0031] In some embodiments of the medical system according to the invention, the holding device is attached to an infusion pole of the medical device or to an edge of the screen and / or monitor of the medical device or to the housing and / or the supporting structure and / or the column.

[0032] Attaching the mounting device to the IV pole of the medical device is advantageous because this pole typically protrudes laterally and vertically from the device at a high position, providing a clear view of the area behind the device. The mounting device can be, for example, an adapter with a clamp on one side that grips the IV pole and is clamped to it. On the other side, the adapter has a mount for the digital video camera, such as a ball head with a 1 / 4-inch or 3 / 8-inch photo thread, or one of the familiar quick-release clamps for attaching a quick-release plate with a digital video camera mounted on it.

[0033] Embodiments with a ball-head mounting device also offer the possibility of rotating or pivoting the digital video camera, starting from a first orientation towards an object space lying in a first direction of movement, into a second direction of movement opposite to the first direction of movement. For example, it can be rotated or pivoted 180° around a vertical axis, such as when the medical device is to be pushed in the opposite direction without rotating the entire medical device around its vertical axis. The person pushing then steps onto the back of the medical device and pushes it from the rear, for example, using a handle on the back of the medical device, with the front of the medical device then pointing in the second direction of movement.This means that, if necessary, the digital video camera can also be rotated or swiveled to the object space located in the second direction of movement.

[0034] Attaching the device to the edge of the screen and / or monitor of the medical device also allows a view of the area of ​​the object space that would otherwise be obscured when the medical device is moved. The same applies to attaching the device to the back of the medical device, facing in the direction of movement when moved, thus providing a clear view of the object space extending in that direction.

[0035] In some particularly preferred embodiments of the medical system according to the invention, the at least one digital video camera is part of a smartphone or is itself a smartphone. In this case, the holding device is a holding device for the smartphone.

[0036] Smartphone mounts are readily available and inexpensive. They are usually adjustable to fit the dimensions of the smartphone. One advantage of these smartphone mounts is that they typically utilize existing smartphones, eliminating the need for a separate digital video camera. Modern smartphones often feature a wide-angle lens, allowing for a more advantageous field of view.

[0037] In other embodiments of the medical system according to the invention, the at least one digital video camera is permanently mounted on the medical device and / or the at least one digital video camera is an integral part of the medical device.

[0038] For example, at least one digital video camera is integrated into the back of the screen and / or monitor, or at least one digital video camera is integrated into or on the housing and / or the supporting structure and / or the column.

[0039] The lens of modern digital video cameras, such as those used in smartphones, has a diameter of only a few millimeters, allowing it, along with the image sensor, to be integrated into a hole or recess in the back of the screen and / or monitor, or into a wall of the housing. In such designs, at least parts of the digital video camera's electronics can be located inside the screen and / or monitor or the housing.

[0040] In some embodiments of the medical system according to the invention, in which the at least one digital video camera is permanently mounted on the medical device and / or is an integral part of the medical device, the at least one digital video camera nevertheless has an integrated screen and is configured by software and / or hardware modules for recording, processing, and playing back the video data stream in real time on the integrated screen of the at least one digital video camera. In such embodiments, the digital video camera is indeed permanently mounted on the medical device and / or is an integral part of the medical device, but otherwise functions independently of the medical device.One possible advantage of such designs is that the digital video camera does not interfere with the hardware and software of the medical device, and implementing the digital video camera hardly makes the regulatory approval of the medical device more complex.In other embodiments of the medical system according to the invention, in which the at least one digital video camera is permanently mounted on the medical device and / or is an integral part of the medical device, the at least one digital video camera is configured by software and / or hardware modules for transmitting the video data stream to the screen and / or monitor of the medical device, so that the video data stream can be played back in real time on the screen and / or monitor of the medical device, wherein the processing of the video data stream takes place in software in the control device of the medical device or in software in the at least one digital video camera.

[0041] A potential advantage of such embodiments is that the video image generated from the video data stream can be displayed significantly larger on the screen and / or monitor of the medical device than is possible on an integrated screen of a digital video camera. Another potential advantage of such embodiments lies in the synergy effect that the processing of the video data stream can be performed in software within the existing control and regulation system of the medical device, thereby advantageously reducing the overall manufacturing costs of the medical system.

[0042] In special embodiments of the medical system according to the invention, in which the video image generated from the video data stream is displayed on the screen and / or monitor of the medical device, the video data stream is played back on a graphical user interface on the screen and / or monitor of the medical device, wherein the video data stream is played back in a second window of the graphical user interface, if at least one other display relating to the medical device is simultaneously displayed in a first window of the graphical user interface.If, for example, the medical device needs to be moved during operation, such as to another treatment room, then it may be necessary for the person moving the device to simultaneously monitor at least one other display relating to the medical device, such as graphical instructions, warnings, or alarms, on the screen and / or monitor. An advantage of such designs is that the video image does not interfere with or even obscure the at least one other display relating to the medical device.

[0043] In preferred embodiments of the medical system according to the invention, the video data stream processing includes software for detecting physical obstacles in the field of view. When an obstacle is detected, the software displays at least a graphic indication of the obstacle and / or a graphical warning about the obstacle and / or an audible warning in the real-time playback of the video data stream. An advantage of such embodiments according to the invention is that the person pushing the device is assisted in detecting obstacles in their field of view, and the risk of a collision between the medical device and the obstacle is further reduced or even prevented.

[0044] To detect physical obstacles, the software can, for example, contain predefined obstacle criteria and analyze the video data stream for obstacles. For instance, a staircase or a door in a wall can be detected by the software by analyzing the line of contact between the floor and the wall. The software can also contain predefined contours of known obstacles, and when such a contour is detected in the video data stream, the presence of the obstacle can be inferred.

[0045] In particularly preferred embodiments of the medical system according to the invention, a detected obstacle in the playback of the video data stream is highlighted by color or by flashing color.

[0046] For example, a detected obstacle in the video image on the screen and / or monitor can be displayed with a colored, illuminated frame. This frame can also be displayed in a flashing pattern. An advantage of such designs is that they reduce the risk of the person pushing the bicycle overlooking or misjudging a detected obstacle in the video image on the screen and / or monitor. This effectively allows the person pushing the bicycle to quickly determine the area of ​​their field of vision where the obstacle is located and, accordingly, to quickly avoid it or stop moving.

[0047] In particularly innovative embodiments of the medical system according to the invention, the capabilities of so-called artificial intelligence (AI) can be utilized. The software for detecting physical obstacles in the field of vision can be programmed, at least in part, based on an AI module for detecting physical obstacles in the field of vision. An advantage of such embodiments can be the detection of obstacles that cannot be described solely by predefined criteria or contours.

[0048] In some embodiments of the medical system according to the invention, the digital video camera is configured to be manually activated by the person.

[0049] For reasons of data protection and privacy, the digital video camera should not permanently film the field of vision, but only when the person pushing the bike needs and / or wants this for safety reasons.

[0050] In addition, the digital video camera can be configured to be manually deactivated by the person.

[0051] In other embodiments of the medical system according to the invention, the medical device and / or the at least one digital video camera has a motion sensor, and the at least one digital video camera is configured to be automatically activated as soon as the motion sensor detects movement of the medical device on the floor surface and / or to be automatically deactivated as soon as, after a predetermined time interval, the motion sensor no longer detects any movement of the medical device on the floor surface. An advantage of such embodiments can be that the digital video camera is only activated when the medical device is moving. Specifying a time interval for the delayed deactivation of the digital video camera can advantageously prevent the digital video camera from being deactivated with every brief interruption of movement.

[0052] In a multitude of embodiments of the medical system according to the invention, the medical device has at least one handle which is designed at least for manual pushing of the medical device by the person and is arranged in such a way that the person can push and / or rotate the medical device by means of the handle without touching the surface of the medical device.

[0053] As a rule, the manufacturer will specify that the medical device should only be pushed using the handle, as applying a pushing force to unsuitable parts of the medical device can lead to damage.

[0054] In yet other embodiments of the medical system according to the invention, the medical device has not only one handle, but for example a handle on a front of the medical device and another handle on the rear of the medical device.

[0055] Since the terms front and rear may not clearly define their exact arrangement in space, especially if the medical device can be pushed from different directions, the present disclosure specifies that the at least one handle is arranged at least on one side of the medical device facing away from the object space extending in the direction of movement, wherein during movement this side of the medical device with the handle is defined as the front of the medical device, and wherein the side of the medical device facing the object space extending in the direction of movement is defined as the rear of the medical device, and the space in front of the front of the medical device is defined as the area where the person is located during movement by pushing.

[0056] In at least many embodiments of the medical system according to the invention, the at least one digital video camera has a surface that is resistant to disinfectants from the clinical environment and is sealed against moisture ingress.

[0057] Disinfecting the external surfaces of a medical device is a common requirement in clinical settings to prevent the spread of colony-forming units of microorganisms.

[0058] For example, the integration of the camera lens into an outer surface can be designed in such a way that as few gaps and / or steps as possible occur on the outer surface, which can prevent deposits from accumulating in gaps and / or on steps and promotes disinfection of the outer surface.

[0059] The medical device of the medical system according to the invention can be a blood treatment machine for extracorporeal blood treatment using an extracorporeal blood tubing system, which can be selected from the group consisting of: hemodialysis machine, hemofiltration machine, hemodiafiltration machine, acute dialysis machine, emergency dialysis machine, CRRT machine, and CKRT machine. The abbreviation CRRT, formerly used, stands for "Continuous Renal Replacement Therapy," while the abbreviation CKRT, more commonly used today, stands for "Continuous Kidney Replacement Therapy." However, the present invention is not limited to the selection of a medical device from the aforementioned examples but can include other medical devices if this appears expedient to a qualified person in a particular case. Brief description of the figures

[0060] Figure 1 shows a view of an exemplary blood treatment machine for extracorporeal blood treatment.

[0061] Figure 2 shows a schematic representation of an exemplary embodiment of a medical system according to the invention.

[0062] Figure 3 shows a schematic representation of a screen display of a medical system according to the invention.

[0063] Detailed description of an exemplary implementation

[0064] An embodiment of the medical system according to the invention is described in more detail below with reference to the figures. Further details and advantages of the invention are described in more detail with reference to the embodiment described in the figures. The reference numerals in the figures have the same meaning throughout all figures.

[0065] Figure 1 shows a perspective view of an example of a medical device according to the present invention, namely an exemplary blood treatment machine 1000 for extracorporeal blood treatment, specifically the applicant's acute dialysis device multiFiltratePRO. The blood treatment machine 1000 has a chassis 1200 with four casters 1250a, 1250b and a housing 1100, which can also be referred to as a support structure or column. The chassis 1200 with the four casters 1250a, 1250b is designed and arranged for the intended placement and / or movement of the medical device on a floor surface. The casters are lockable so that the blood treatment machine 1000 cannot roll away unintentionally when it is placed as intended. The casters also allow the blood treatment machine 1000 to be moved over minor unevenness in the floor surface.Furthermore, the blood treatment machine 1000 has a handle 1600a on its front and a handle 1600b on its rear. The handles are designed and positioned for manual pushing of the medical device by a person, allowing the person to push and / or rotate the device using either handle 1600a or 1600b without having to touch the surface of the blood treatment machine 1000. It is a manufacturer's requirement that the medical device be pushed only using the handle, as applying force to unsuitable parts of the device could cause damage, and contact with the hands could lead to the spread of germs. The blood treatment machine 1000 also features an infusion rod 1500, on which solution bags, for example, containing a physiological priming solution, particularly a NaCl solution, can be suspended.Furthermore, the blood treatment machine 1000 has a screen 1400, also referred to as a monitor, in its upper section. The blood treatment machine 1000 shown in Figure 1 is prior art. The blood treatment machine 1000, including the screen 1400, has a considerable height. The screen 1400 is positioned at eye level for ease of use by a standing person. A person standing in front of the blood treatment machine 1000 cannot see, or cannot see completely, the area behind the machine because the dimensions of the blood treatment machine 1000 partially or completely obscure this area.

[0066] Figure 2 shows a schematic representation of an exemplary embodiment of a medical system according to the invention using the blood treatment machine 1000 shown in Figure 1, wherein the medical system is shown in a side view. The medical system includes a digital video camera 5000, which is arranged on the blood treatment machine 1000. The digital video camera 5000 is configured and arranged to generate a video data stream of a predetermined field of view in real time, wherein the field of view 5300 comprises at least a part of the object space 3000 extending in the direction of movement 3100. The medical system is shown in a medical environment in Figure 2. The blood treatment machine 1000 stands on a floor surface 3200, on which it can be moved, in particular pushed, in a direction of movement 3100.The direction of movement 3100 is indicated in the schematic diagram by a large arrow pointing in that direction. A small arrow next to the letter "g" shows the direction of the acceleration due to gravity, which causes the blood treatment machine 1000 to stand on the ground surface 3200. In a designated area 2100, a person 2000 is depicted, sketched only by their outline, who can push the blood treatment machine 1000. It is clear that the person cannot see, or cannot see completely, an object space 3000 located behind the blood treatment machine 1000 from their perspective, because the dimensions of the blood treatment machine 1000 partially or completely obscure this object space. An example obstacle 4000, which the person 2000 cannot see, is indicated by a dotted line within object space 3000.The digital video camera 5000 has a field of view 5300, which defines the area within the camera's field of view within which objects, events, or changes can be perceived and recorded. The field of view is defined by a horizontal angle of view and a vertical angle of view and / or a diagonal angle of view, these angles resulting from the focal length of the lens 5700 and the arrangement and size of the image sensor in the digital video camera 5000. In Figure 2, only the vertical angle of view y is indicated by two dashed lines, which intersect at angle y in the side view shown. Furthermore, possible fields of view of the person 2000 on the screen 1400 and the digital video camera 5000 are indicated by dashed lines, again only by the vertical angles a and β.The digital video camera 5000 is mounted at the top of the infusion pole 1500 by means of a holding device 5500, implemented in this example as an adjustable tripod ball head. This position is particularly advantageous because the object space 3000 can be captured essentially completely from this position, and the arrangement of the digital video camera 5000 in this position does not interfere with the use of the blood treatment device 100. Furthermore, the digital video camera 5000 can be rotated by, for example, 180° around the vertical axis using the ball head when the blood treatment machine 1000 is to be moved using the second handle 1600b, so that the first handle 1600a then points in the direction of movement.

[0067] Person 2000 can push the blood treatment machine 1000 in the direction of travel 3100 using their hands on the handle 1600a, while viewing the screen 1400 or 5100, and recognize the obstacle 4000 indicated on the video image (in this example, a trolley for a hospital bed) in time. This allows the person to avoid a collision between the blood treatment machine 1000 and the obstacle 4000, for example, by pushing the blood treatment machine 1000 around the obstacle while keeping an eye on the screen 1400 or 5100, or by interrupting the movement, removing the obstacle, and only then resuming the movement of the blood treatment machine 1000.

[0068] The digital video camera 5000 shown can be a smartphone, wherein in such embodiments the person can see the filmed field of view directly in real time on the integrated touchscreen of the smartphone, indicated in Figure 2 by the vertical angle a.

[0069] Alternatively, the digital video camera 5000 shown is connected to the control and regulating device 1300, indicated in Figure 2 only by dotted lines. In such embodiments, the person can see the filmed field of view directly in real time on the screen 1400 of the blood treatment machine 1000, indicated in Figure 2 by the vertical viewing angle β. An advantage of such embodiments is that the screen area available for the video image can be significantly larger than, for example, on a smartphone, and obstacles can be detected more easily. Furthermore, the video data can be displayed in a separate window, so that other windows, for example, for monitoring operating data of the blood treatment machine 1000, can be viewed clearly and simultaneously on the same screen. Figure 3 shows a schematic screen representation of such an embodiment according to the invention.The screen 1400 features a touchscreen 1415 as an embodiment of the graphical user interface 1410. Two windows 1420 and 1430 are displayed on the touchscreen 1415, with the second window 1430 displaying the video data stream of the filmed field of view. Obstacles 1440, in the form of a partially open door in a wall and a staircase, are schematically indicated in the second window 1430. The person pushing the blood treatment machine 1000 can advantageously detect these obstacles in the second window 1430 in time and prevent a collision between the blood treatment machine 1000 and the obstacles.

[0070] Independently of this, a first window 1420 displays operating data for the blood treatment machine 1000, for example, a graphical representation of a monitored pressure over time. The second window 1430 is only displayed on the touchscreen when movement of the blood treatment machine 1000 is detected. In this embodiment, this movement is detected by a motion sensor 5600a, 5600b and transmitted to the control device 1300 (not shown in Figure 3). The digital video camera 5000 is only activated in this embodiment when movement of the blood treatment machine 1000 is detected.
