Description

The present invention relates to a mobile documentation device according to claim 1 or according to the preamble or generic term of this claim.

When documenting healing-specific parameters of wounds or skin lesions, a two-dimensional image of the wound or skin lesion is usually recorded with a conventional digital camera. A ruler held in the image should enable an objective assessment of the wound size.

Wound care for a patient is often performed by a variety of different healthcare professionals and/or over extended periods of time. For this reason, the course of the treatment must be documented as precisely as possible so that all therapists involved can reliably assess whether the treatment measures undertaken so far are/were successful or whether complications have arisen.

It may be the object of the present invention to specify a further documentation device which enables reliable and precise documentation of the course of the healing processes of wounds and other skin lesions.

The object according to the invention is achieved by a mobile documentation device having the features of claim 1.

The present invention relates to a mobile documentation device for the acquisition, data acquisition, evaluation, three-dimensional pictorial representation and/or documentation of skin lesions, for example wounds.

The mobile documentation device (hereinafter also briefly: documentation device) has a number of recording modules, which in turn each comprise either at least one, mostly optical, camera and at least one light source or at least one thermal imaging camera.

The light source, if available, is used to illuminate the wound or skin lesion (hereafter referred to as “wound”), preferably without shadows. In this way, images can be obtained independently of the ambient lighting conditions and/or under reproducible lighting conditions, for example by means of the optional optical camera(s).

The recording modules of the documentation device are connected to one another in an articulated manner by means of one or more joints, e.g. B. can adopt a completely or substantially arcuate arrangement. Here, the receiving modules are not connected to one another in a closed-circumferential structure; H. they are not connected to one another in the form of a ring, an ellipse, a polygon, each with a central opening, or the like. In addition or as an alternative, the mobile documentation device is not or has no structure that is closed in its circumference.

In use, the mobile documentation device is placed over the patient's affected wound, for example set up, or held over the affected area by the user.

Embodiments according to the invention can have some, some or all of the following features in any combination, insofar as this is not clearly technically impossible for a person skilled in the art. Advantageous developments of the present invention are also the subject matter of the dependent claims and embodiments.

In all of the following statements, the use of the expression “can be” or “can have” etc. is to be understood synonymously with “is preferably” or “has preferably” etc. and is intended to explain embodiments according to the invention.

Whenever numerical words are mentioned herein, the person skilled in the art understands them as indicating a numerical lower limit. Provided that this does not lead to a discernible contradiction for the person skilled in the art, the person skilled in the art always reads “at least one” or “at least one” when specifying “a” or “an”. This understanding is also encompassed by the present invention, as is the interpretation that a numerical word such as "a" can alternatively be meant as "exactly one" wherever this is clearly technically possible for a person skilled in the art. Both are encompassed by the present invention and apply to all numerals used herein.

Advantageous further developments of the present invention are the subject matter of subclaims and embodiments.

Where reference is made herein to an embodiment, this represents an exemplary embodiment according to the invention.

If it is disclosed herein that the object according to the invention has one or more features in a specific embodiment, it is also disclosed herein that the object according to the invention expressly does not have this or these features in other embodiments that are also according to the invention, e.g. B. in the sense of a disclaimer. For every here In the embodiment mentioned, it is therefore the case that the opposite embodiment, for example formulated as a negation, is also disclosed.

Where “programmed” or “configured” is used herein, it is also disclosed to interchange these terms.

In some embodiments, moreover, there are no connectors or no other provisions are made to provide the receiving modules in a closed arrangement along the periphery of the mobile documentation device.

In some embodiments, the receiving modules have hinges on more than one side of the receiving module. In this way, receiving modules can be connected to one another both along a longitudinal axis and along a transverse axis of the receiving modules. In this way, an individualized arch can be built on or around the patient in a simple manner in order to be able to quickly, completely and accurately record even complex, stretched and/or unusually shaped wounds, such as burns, even if they are on the neck or shoulder , lateral areas of the thorax and/or other parts of the patient's body that are difficult to access.

In some embodiments, the documentation device has at least one handle with which the documentation device can be held over the wound for use. Alternatively or additionally, finger grips, finger recesses and/or the like can be provided.

In some embodiments, some or all of the modules may include not only hinges, but also other connection mechanisms such as snap mechanisms, rails, hooks, magnet connections, etc.

In some embodiments, all or some of the joints, the optional other connection mechanisms or the receiving modules can have one or more motors or can be provided to be moved by a motor, preferably relative to a respective directly or indirectly adjacent receiving module.

In some embodiments, such optional motors bring and/or hold the receiving modules in the desired position, for example relative to adjacent receiving modules.

In some embodiments, a control device can be programmed to control the motor or motors in order to position the receiving modules based on known position values, e.g. B. relative to each other or relative to an adjacent recording module to position. Such known position values, or positions, can e.g. B. be stored as reference values in a memory device or manually set / entered by the user.

Such position values can be angular positions, distances between specific recording modules or parts thereof, or the like.

A storage device, if provided, can be part of the mobile documentation device, or part of a system that has the documentation device.

The memory device and the control device can be in signal connection with one another in a wired or wireless manner, at least when the documentation device is in use, or be prepared for this.

If a signal or communication connection between two components is discussed here, this can be understood to mean a connection that exists during use. This can also be understood to mean that there is a preparation for such a signal connection (wired, wireless or implemented in some other way), for example by coupling both components, for example by means of pairing, etc.

Pairing is a process that takes place in the context of computer networks to create an initial link between computer units for the purpose of communication. The most well-known example of this is the establishment of a Bluetooth connection, by means of which various devices (e.g. smartphone, headphones) are connected to one another. Pairing is also sometimes referred to as bonding.

In a further embodiment, the images recorded by the recording modules and measured/collected parameters are stored; a data memory provided and prepared for this purpose is provided in such embodiments.

In some embodiments, the mobile documentation device according to the invention has at least one actuating device, by means of which the recording modules or their cameras and/or sensors are actuated.

The actuation of the recording modules or cameras and/or sensors can, in particular take place simultaneously. Alternatively, a successive actuation or activation of the individual recording modules or cameras and/or sensors, with or without a predetermined order, ie in any order, or in a predetermined order, is also covered by the present invention.

In some embodiments, at least one of the recording modules has at least one thermal imaging camera. This can be provided in addition to or as an alternative to the optical camera disclosed herein.

In some embodiments, at least one of the recording modules also has at least one sensor, in particular a temperature sensor, an IR sensor and/or a color sensor.

In certain embodiments, the sensor system is designed to determine or ascertain further parameters that provide an indication of the development of the healing process of the wound under consideration.

According to the invention, the mobile documentation device can have more than one type of sensor in order to be able to make more precise statements.

For example, an increase in temperature measured using an optional temperature sensor, for example over different examination times in which the documentation device according to the invention was used, can be an indication of a complication of the wound (inflammation or infection), alternatively it can also be an indication of a wound that is favorable for healing Tissue revascularization if there was previous ischemia (poor blood flow).

Additional sensors, such as IR sensors or color sensors, can be provided to provide additional information according to the invention and, for example, expand or supplement the information received from the temperature sensor(s) in such a way that the clinical value of the temperature change can be determined more precisely .

The values determined by the sensors can provide information on the development of the healing process (also documented over longer periods of time), e.g. B. with regard to the formation of granulation tissue or the epithelialization of the wound surface of the wound, or the development of complications such as infection (s), poor blood flow, in the worst case necrosis, etc., indicate.

In some embodiments, at least one of the recording modules and/or another section of the documentation device has at least one distance sensor, in others exactly one, in still others precisely or at least two distance sensors.

In some embodiments, the distance sensor can determine the correct positioning of the mobile documentation device, for example so that it is always placed on the patient at the same point during successive measurements. The control device can be designed and/or programmed accordingly for this purpose.

In further embodiments, the distance sensor or the distance sensors can serve or exclusively serve to produce lifelike 3D images of the wound or contribute to this, for example by determining the depth of the wound.

In some embodiments, at least one of the recording modules and/or another section of the documentation device has at least one inclination sensor. Inclination sensors can be provided in order to give the user, when holding the documentation device, indications of how the latter is being held at the respective moment. A comparable principle is known from spirit levels. One or two inclination sensors indicate whether the spirit level is aligned in one or two spatial directions "standing in the water". A documentation device with inclination sensors can use optical or other feedback to encourage the user to keep the documentation device straight or always at the same angle at different times during each examination of the wound. The documentation device, which is always kept identical or at least comparable in at least one or more spatial directions, allows images to be recorded at different points in time, which enables a reconstruction or the creation of 3D models with comparatively less computing effort. This applies all the more if the height of the documentation device above the wound is known at the moment when the respective recording was made based on data from the distance sensor or the documentation device is held according to the specifications of the distance sensor or information determined by it.

In some embodiments, the receiving modules are detachably connected to one another. In this case, different receiving modules can be combined with one another or with one another.

The combinability of the recording modules enables the documentation device to be adapted to the individual needs of the specific case, the wound examined or the specific patient in just a few simple steps.

The mobile documentation device can be designed in such a way that the entire surface of the wound is optimally recorded, regardless of where the wound is located on the patient's body and how large its surface is.

According to the invention, the recording modules of the documentation device can, for example, form a wide arc of several rows of recording modules to document extensive thoracic injuries, or a slim, short arc, built or formed from a few interconnected recording modules, to record small wounds on extremities, for example.

In further embodiments, receiving modules can be combined, i. H. have different camera and/or sensor types.

In some embodiments, the mobile documentation device or its recording module has a control device.

In further embodiments, the control device is configured for automatic or manual control or regulation of the function of the camera(s) or the sensor(s).

In some embodiments, the control device is configured to automatically or manually calibrate cameras and/or sensors of the mobile documentation device and/or to influence and/or adjust parameters of the cameras and/or sensors such as angular positions, for example relative to the wound or relative to one another to change.

In some embodiments, the control device is configured, for example, to adjust an angular setting of the camera(s) and/or the sensor(s) to the corresponding position on a patient's body or to the specific area and depth of the wound with the aim of providing the best possible camera images or Ensure measured values of the sensor or sensors.

In further embodiments, the control device can adapt the light source(s) in such a way that the wound is illuminated essentially without shadows.

In some embodiments, the controller may be programmed to control motors responsible for moving cameras, sensors, and/or joints of the acquisition modules.

In some embodiments of the mobile documentation device according to the invention, the intensity and/or the alignment and/or the dimensions (size and shape parameters) of the light cone of the light source can be adjusted manually or automatically.

In some embodiments of the documentation device, existing cameras and/or sensors are pivotable and/or displaceable in the respective recording module.

For this purpose, according to the invention, in some embodiments the receiving modules have suitable devices, e.g. B. motors, which can be controlled, for example, by the control device and / or by an evaluation device.

In some embodiments, the documentation device has an evaluation device or is connected to an evaluation device.

The evaluation device is preferably configured or programmed to determine or collect data, to convert the data determined in this way into images and/or to compare these images with other images, which were calculated in particular on the basis of earlier data.

In some embodiments, the evaluation device is configured to create three-dimensional models of wounds based on the data determined by the mobile documentation device.

The model created by the evaluation device can, for example, include physical parameters of the wound, such as e.g. B. area and depth, and / or physiopathological features of the wound, such. B. temperature, discoloration, signs of vitality of the tissue, etc., which can be represented, for example, on the model as numbers or color codes.

3D models (or their mathematical description, mapping, etc.) captured or generated on different days are stored in some embodiments. In some embodiments, they are compared to one another at the instigation of a user or automatically, such as to provide chronological documentation of the progression of the wound.

"Determining" or determining, in particular of data and/or values, can include examining the existence or non-existence, detecting, recording, measuring, collecting, evaluating, processing, comparing, estimating, assessing or be or include estimating, inferring, calculating, obtaining, attaining and/or recognizing.

In some embodiments, the evaluation device can make prognostic statements regarding the course of the healing process or can trigger an alarm message if there are signs of a complication in wound healing. This can e.g. B. by comparison with stored reference data, reference profiles, reference images, through the use of reference databases, use of artificial intelligence, etc.

In some embodiments, the evaluation device can be designed as a user interface, be connected to one—preferably wirelessly or wired—or have one, by means of which the cameras, sensors, light sources and/or control devices of the recording modules can be controlled. In some embodiments, it can also include the actuating device or have a signal connection with it.

In some embodiments, the evaluation device can be controlled by voice and/or by means of gestures and can be configured or programmed accordingly.

In some embodiments of the documentation device, the evaluation device is integrated in at least one of the recording modules.

In some embodiments, at least the evaluation device has a display for data reproduction and/or for controlling the mobile documentation device and/or as a user interface for inputting control signals for controlling the mobile documentation device.

In some embodiments, the display is a touch screen.

In some embodiments, the at least one evaluation device is physically separate from the mobile documentation device, has a wireless signal connection with it, or is prepared for this. The evaluation device is optionally configured to remotely control the documentation device.

In some embodiments, the evaluation device can exchange data with remote computer systems and be prepared accordingly and/or have a signal connection in order to enable remote diagnostics, for example.

In some embodiments, the evaluation device is part of the set according to the invention. It can be on the documentation device or external to it.

In some embodiments, the mobile documentation device can be sterilized or disinfected.

Some or all embodiments according to the invention can have one, several or all of the advantages mentioned above and/or below.

Conventional documentation systems that are based on two-dimensional images do not enable reliable documentation of the course of wounds or wound healing due to unavoidable measurement inaccuracies, particularly in the case of large-area lesions. These recordings are not suitable as the sole source of assessment. Depending on the lighting, shooting angle and position of the ruler, the significance of such shots can vary.

An advantage of the present invention can be that it is quickly available at a place of use due to its compact, mobile design. In some embodiments, it is approximately the size of a shoulder bag, a trolley case, a small (hand luggage) suitcase, etc. Due to its low weight, for example approx. 1.5 kg in some embodiments, it can be used directly during the examination of a patient be used on site. The patient can thus be spared a trip to an examination device. This makes outpatient examinations easier.

A further advantage of the invention can consist in the fact that many decisive wound parameters can be recorded at the same time. In addition, a complete 3D model of the wound can be created from the recorded parameters, which in certain embodiments not only documents the size or extent (area/depth) of the wound by means of analysis of color, wound edge, moisture and/or tissue type but also data on vitality, blood flow, inflammation, wound healing and/or the like. This can help those treating the wound to arrange for proper care of the wound.

By means of the present invention, a patient's wound can be recorded or examined within a very short time. This advantageously helps to save time and money and also does not burden the patient unnecessarily.

Another advantage of the invention may be its ease of use. In certain embodiments, intuitive LEDs indicate correct positioning, for example by glowing green, and the triggering process itself takes around 0.1 seconds in certain embodiments. After approx. 60 seconds, the results can be viewed both on the display built into the device and on the computer used by the person treating you. The therapists, who are under great time pressure, can advantageously use the resulting freedom, e.g. B. for analysis and therapy planning.

The ability to disinfect the invention enables the invention to be used in clinical settings and may represent a further advantage.

Furthermore, the reliable, detailed recording of the wound parameters can also be advantageous even when the patient is moving. This can be particularly beneficial when treating chronic wounds. Chronic wounds often occur as an accompaniment to other diseases that make it impossible for the patient to remain still for a long period of time, for example due to tremor. In the invention, all parameters are recorded simultaneously within 0.1 seconds and the quality of all recordings is always the same, even if the patient is trembling during this time or the recording is reproduced from a different camera angle.

Since the most important characteristics of the wound (such as diameter, depth, reddening, perfusion status, vitality, temperature, inflammation, exudate and/or the presence of specific tissue types, especially at the edge of the wound, such as swelling, potential necrosis , etc.) can be detected in a short time, the present invention can also be easily applied to wound observation over time. Since the medical standards require the documentation of chronic wounds at regular intervals, the present invention can also support the treating person here. In particular, the present invention can be helpful in the time-efficient and objective assessment of the success of the therapy.

In addition, the invention can offer further additional benefits, such as the provision of forecasts based on the course of the healing process over time. In addition or as an alternative, it can send warnings, for example if there are indications of upcoming or emerging complications, such as the development of an infection or reduced perfusion of the tissue. Such information can in turn be used as a decision-making aid during treatment, for example to determine when a doctor should be involved in the treatment.

• 1 12 shows a mobile documentation device 100 for collecting information about skin lesions, for example wounds, in a first embodiment and in perspective.

The mobile documentation device 100 comprises a plurality of receiving modules 101a, 101b and 101c which are connected to one another to form a structure which is not closed in perimeter. So they don't form a ring, an ellipse or a rectangle. They form in the example of 1 exemplarily a semicircle or the arc of 1 .

For its use, the mobile documentation device 100 is placed over a wound so that the body part with the wound lies under the arc formed by the receiving modules 101a, 101b, 101c, as e.g. Am 1 is shown.

The main module 101a and/or the receiving modules adjacent to the main module 101a or other sections of the mobile documentation device 100 can have handles with which the user can hold the mobile documentation device 100 in his hand.

In a further embodiment, the mobile documentation device 100 can be designed in such a way that it can be set up above the patient, for example on a lying surface.

In the example of 1 seven receiving modules 101a, 101b, 101c can be seen, which are connected to one another, in particular detachably. One of the recording modules forms the main module 101a and includes an evaluation device. In 1 it is centrally located, but in other embodiments it may alternatively be provided at any other position. Here, the main module 101a is optionally not connected in an articulated manner to the two receiving modules 101b directly adjacent to it.

The mobile documentation device 100 further comprises two end-side receiving modules 101c, which close off the arc-shaped mobile documentation device 100 at its two ends or are at least the receiving modules located furthest to the outside. The end receiving modules 101c are in use with their free ends z. B. on the patient bed surface on which the patient is lying.

The existing width of the receiving modules 101c at the end allows the mobile documentation device 100 to be placed in a stable position. The receiving modules 101c at the end can optionally have a foot or a cap or the like, possibly also foldable, removable, etc., on which the mobile documentation device 100 can stand with sufficient stability.

Additionally or exclusively, the mobile documentation device 100 can include one or more handles.

The number of receiving modules 101a, 101b, 101c is purely exemplary and should not be understood as limiting.

As in 1 shown, the recording modules 101a, 101b, 101c each comprise at least one camera 103 and at least one light source 105 for illuminating the wound, which is not shown.

The number and position of cameras 103 and light sources 105 in 1 is also purely exemplary and not to be construed as limiting. Any technically possible number and positioning of these components is covered by the invention.

In addition to the camera 103, sensors with a wide variety of modes of action can also be arranged in the recording module, for example distance, IR, color and/or temperature sensors as shown in FIG 2 described in more detail. These can also be attached next to or around cameras 103 in the recording module 101a, 101b, 101c.

In 1 the light source 105 is shown separated from the camera 103 . In other embodiments, the light source 105 can be integrated into the camera 103 and/or arranged in a ring around the lens of the camera 103 .

At least one of the cameras 103 can be designed as a thermal imaging camera.

The receiving modules 101a, 101b, 101c are connected to one another in an articulated manner by means of articulated sections 130. For a better overview, these are in 1 surrounded by dashed rectangles.

The hinge portions 130 may include any configuration known in the art. Preferably they are easy to sterilize or disinfect.

Receiving modules 101a, 101b, 101c can also include other connection mechanisms, such as rails, hooks, latching mechanisms, etc. The connection mechanisms can be connected to one another in any way.

In this case, purely by way of example, an evaluation device 115 is integrated into the main module 101a. In 1 only a display 117 of the evaluation device 115 is shown.

The evaluation device 115 can be configured and/or programmed to collect data and/or to process and/or compare images. In addition, it can create three-dimensional models of wounds based on the data recorded or measured by the mobile documentation device or its components.

The evaluation device 115 can create a chronological documentation that reflects the course of the healing process of the wound. It can issue both prognostic statements about this course and/or warnings if, for example, there are indications of a complication in the healing process, for example indications of an infection, a wound healing disorder, tissue hypoxia, etc.

In further embodiments, the evaluation device 115 can preferably additionally be configured to monitor cameras 103, sensors 109, 111 (in 1 not shown), light sources 105 and/or in some embodiments present control devices 113 (in 1 not shown) of the recording modules 101a, 101b, 101c.

Can be seen in 1 an optional display 117 of the evaluation device 115. This can be used for data reproduction and/or for control and/or as a user interface for inputting control signals for controlling the mobile documentation device 100.

The various recording modules 101a, 101b, 101c can preferably be combined with and among one another, supplemented, etc. in such a way that any lengths and widths of a wound to be viewed can be covered by the mobile documentation device 100. This can help to reconstruct lifelike 3D models. For smaller wounds, for example on the extremities, a small arch or a narrower arch can be put together with a few recording modules. In the case of large-area wounds, a more complex documentation device 100 can be assembled from or with significantly more recording modules 101a, 101b, 101c, e.g. B. having several sheets of recording modules 101a, 101b, 101c parallel to each other. Reference is made to the examples in 5 until 7 .

The embodiment of 5 has only two equally long, first and second rows of recording modules 101a, 101b, 101c with only one evaluation device 115, the second row of recording modules 101a, 101b, 101c parallel to the first row of the mobile documentation device 100, the z. B. that of 1 can accordingly, is arranged.

The mobile documentation device 100 of 6 has four such series, the mobile documentation device 100 from 7 also has 4 rows of receiving modules 101a, 101b, 101c, but these rows have different lengths.

The mobile documentation device 100 can assume a large number of possible forms through the combination of the recording modules 101a, 101b, 101c.
