Description

The invention relates to a mobile video recording system for patient simulation.

In medicine, patient simulation is becoming increasingly important. It trains critical situations on a simulator. This allows the medical staff to be optimally prepared for these critical situations (eg respiratory or cardiac arrest). The use of a simulator is very costly. But to be able to do an optimal evaluation (DeBriefing), the training should be recorded. So you can go into the subsequent DeBriefing directly on the training. Since sometimes several people are involved in a training, the recording is becoming increasingly important. Applicants, it is known that in existing simulation centers in Germany for permanently installed audio and video systems are used. These are mostly at universities. The largest is in Tübingen (TüPASS). Several technicians are needed for the operation. When setting up a simulation center in Werdau it became clear that such a recording system would have to be mobile. So far, the medical staff has been invited to the simulation center for the training sessions in order to complete the simulations there. A stimulation on site z. In hospitals, operating theaters, practices or in the military field can not be performed.

Dieckmann, P. u. a describes in his article "On the Principles for the Design of Simulator Settings for Research and Teaching", Harburger Beiträge, ISSN 0944-565X, No. 31, June 2002, p. 6-7, the basic course of a simulator settings using its elements using a common simulator group in a simulated operating room of a simulator center.

Out WO 03/001359 A2 a method for simultaneous recording of measurement data and video and / or audio data is known in which measurement data is recorded by a measurement data recording device and transmitted to a data processing device, wherein in particular the linkage of the measurement data of the patients is described.

The DE 195 34 312 A1 describes a method for outputting and archiving image information from surgical theaters, in which an analog video signal is generated by means of an image acquisition device. It describes the storage and playback of X-ray generated images of the patient (image information).

A mobile "video recording system for patient simulation", which can be built easily at the place of need, could not be determined. All of the prior art solutions are stationary solutions, so that all participants in the simulation must travel to the locations of the simulators.

The object of the invention is to provide a mobile video recording system that allows flexible patient simulation at different locations.

According to the invention the object is achieved by the features of the main claim. Embodiments of the invention are shown in the subclaims.

The advantage of the invention is that the video recording system according to the invention is very compact, wherein the operation is reduced to a minimum and to be operated by a person. The video recording system is inexpensive and can be transported in a car.

The invention will be explained in more detail with reference to an embodiment. The accompanying drawing shows

1 a video recording system according to the invention,

2 : a mobile stage track 1 and

3 : a connection box 16 ,

In 1 an inventive video recording system is shown. It contains a mobile, for example mobile, stage track 1 , a known patient simulator 2 , Video cameras 3 , one to the patient simulator 2 connected simulation monitor 4 with a VGA video converter 5 , To the stage track 1 is a projector 6 connected via which the image data on a screen 7 are displayed; The sound data are via active boxes 8th output. About a first microphone 9 can through speakers 10 Sound signals near the patient simulator 2 be output via a second microphone 11 can be sound signals from the vicinity of the patient simulator 2 to a PC-based VCR, such as a video server 12 , in the stage track 1 . 2 , for distribution to the active speakers 8th be sent.

The stage track 1 is in 2 shown. It contains the video server 12 to the one screen 13 , for example, a 15 '' TFT screen, with a pull-out keyboard 14 connected, as well as an audio mixer 15 and a connection box 16 at the back of the stage track 1 represented in 3 ,

In 3 is the connection diagram of the connection box 16 shown. Therein are the connections 1 to 4 the video inputs, connection 5 for the second microphone 11 , Connection 6 for the upper speaker 10 , Connection 7 for the loudspeaker located at the head of the patient simulator 10 , Connections 8th and 9 for the audio signals for the beamer 6 , Connection 10 the VGA connection, connection 11 for the screen 13 and connection 12 for the projector 6 ,

The mobile video recording system is in a mobile stage track 1 (Flightcase) and includes the complete audio and video system. The basis is a PC-based video recorder, such as the video server 12 , which was compiled from standard components and optimized for the interests of me. This is one 15 '' TFT screen 13 and a pull-out keyboard 14 connected. There is also a standard two-channel audio amplifier, an audio mixer, and a control panel. For optimal and safe connection of the audio and video cables, the junction box 16 developed. This is located on the back of the stage track 1 and is accessible via a flap from the outside.

The PC based video recorder, so the video server 12 , has four analog video inputs which are digitized and stored. For the video recording are three analog video cameras 3 used and to the junction box 16 connected. The signal for the fourth channel is from the simulation monitor with the aid of a signal converter 4 (belongs to the simulator) and taken to the junction box 16 connected. The display and recording of the four analog video signals takes place simultaneously. The audio signal is recorded via a central microphone 11 , In addition, it is possible to integrate the subjects via audio headsets with up to four microphones. This improves the audio quality.

The audio signals are on the audio mixer 15 in the stage track 16 mixed and the video server 12 fed. Furthermore, there are two audio paths from the stage track 16 to the simulation site. The instructor can influence the action via the control panel. In playback mode is via a projector 6 and an audio system recorded the recording for decryption. The instructor can drive to any position in the recording and play it back. The connections are also located on the connection box 16 , The entire solution was designed so that a person can use the mobile video recording system with minimal effort.
