Description

BRIEF DESCRIPTION OF THE INVENTION

[0026] The invention is described below without limitation of the general concept of invention by means of embodiments with reference to the drawings, in which:

[0027] FIG. 1 shows a plan view of a resuscitation dummy designed according to the solution,

[0028] FIG. 2 shows a representation of the first and second fluid line system with mechanical pump, and

[0029] FIG. 3 shows fluid couplings with modular exchangeable fluid line segment.

EMBODIMENTS OF THE INVENTION, INDUSTRIAL APPLICABILITY

[0030] FIG. 1 shows a plan view of a resuscitation dummy 1, which is designed according to the solution and which comprises a dummy body 2, which models the human torso, and a groin area 3, which is directly connected to the dummy body and which comprises a left and right upper thigh area 3′, 3″. A dummy head 4 is attached to the shoulder area of the dummy body 2 and has a mouth-like opening 5 and two nostril openings 6, which are fluidically connected to the mouth-like opening 5.

[0031] For the purpose of carrying out mouth-to-mouth resuscitation as realistically as possible, the mouth-like opening 5 and the nostril openings 6 are fluidically connected via at least one air channel running inside the dummy head 4 and dummy body 2 to a bag modelling the human lung, which bag is arranged in the region of the sternum 7.

[0032] Before reference is made to the openings 12, 13, 14 within the dummy body 2 and the right and left upper thigh areas 3′, 3″ shown in FIG. 1, which openings are each closed with a body 9, 10, 11 that can be examined sonographically and punctured, reference is made to the explanation of the fluid line system located inside the resuscitation dummy 1 and illustrated in FIG. 2.

[0033] FIG. 2 illustrates the fluid line system arranged within the resuscitation dummy. The central component is a manually actuatable, mechanical pump 15, which is located inside the dummy body 2 in the area of the human sternum 7. Fluidically connected to the manually actuatable pump 15 is a first fluid line system 16, which is framed by a dashed line in FIG. 2. The first fluid line system 16 models the human blood circulation system in schematised form and is composed of venous 17 and arterial 18 fluid line segments that can be associated with the human abdomen as well as venous 19 and arterial 20 fluid line segments that can be associated with the human groin area. For the purpose of puncturing and cannulation, arterial and venous fluid line segments are arranged in the region of the abdomen below the opening 14 shown in FIG. 1 and in the left and right upper thigh area 3′, 3″ below the openings 12, 13 shown in FIG. 1, where possible in accordance with the human anatomy with regard to shape, size and relative spatial arrangement. In FIG. 2, these areas are covered by the bodies 9, 10, 11 that can be examined sonographically and punctured, these bodies also being shown in FIG. 1.

[0034] When the pump 15 is actuated, a flow oriented by the arrows shown in FIG. 2 is impressed along the first fluid line system 16 and flows, starting from the pump 15, firstly through the arterial fluid segments 18, 20 and then through the venous fluid segments 19, 17.

[0035] In the area of the venous and arterial fluid line segments 17, 18, which can be associated with the abdomen, there is fluidically connected a second fluid line system 21 which, parallel to the first fluid line system 16, is likewise fed and also passed through by a fluid flow, driven by the manually actuatable pump 17. A fluidic interface 22 is introduced along the second fluid line system 21, to which fluidic interface an extracorporeal fluid circuit 23 can be coupled. Along the extracorporeal fluid circuit 23, at least one component 24 of the following components can be fluidically coupled outside the resuscitation dummy 1: fluid reservoir, fluidic open-loop and/or closed-loop control unit for presetting and/or varying an absolute and/or pulsatile fluid flow pressure within the first fluid line system, degassing unit, patient simulator.

[0036] The second fluid line system 21 shown in FIG. 2 is indicated in FIG. 1 by the lines 21′ leading away from or leading to the resuscitation dummy 1.

[0037] In the knowledge of the first and second fluid line systems 16, 21 illustrated in FIG. 2, and the manually actuatable mechanical pump 15 fluidically connected to them, puncture and cannulation procedures can be carried out on the resuscitation dummy 1 shown in FIG. 1 in the following manner:

[0038] The openings 12, 13 and 14 are completely covered by the bodies 9, 10, 11 that can be examined sonographically and punctured and that are made of non-transparent material. This creates the most realistic situation possible. For the exact location of the fluid line segments to be punctured, which are located directly below the bodies 9 to 11, a conventional mobile ultrasonic device is preferably suitable. Since the bodies 9, 10, 11 that can be examined sonographically are preferably made of a medical synthetic gel, this will hardly cause any artefacts or disturbances in the ultrasonic locating. The person in charge of puncture and cannulation can always perform ultrasound-monitored vascular puncture in the area of openings 12 and 13 and can check the position of the wire and cannulas. Typically, no puncture is performed in the area of opening 14, and instead the position of a guide wire is checked here with the aid of an ultrasound probe, which is placed in the area of openings 12, 13 after a puncture and is advanced along the fluid lines.

[0039] As an alternative or in combination with the performance of an ultrasound-monitored puncture and cannulation, an RFID chip can be arranged in the area of at least one of the openings 12, 13, 14 and can be detected by a simulated transducer with RFID antenna. Instead of a live image of the body area detected by a real ultrasound probe, an ultrasound device can be simulated with the aid of RFID technology and, in conjunction with sectional images stored on a data carrier, can be visually displayed on a suitable visual display unit. In addition, further RFID chips can be attached at suitable locations within the dummy body, which makes it possible to increase the complexity of medical exercises, for example by adding complex combinations of findings or pathologies.

[0040] In order to keep the preparation of the resuscitation model between multiple applications as short and simple as possible, the punctured and thus leaking fluid line segments must be replaced as quickly and easily as possible. FIG. 3 shows a preferred design for rapid modular replacement of punctured fluid line segments 25, 26, along which a body that can be examined sonographically and punctured, preferably in the form of a medical synthetic gel 9, 10, is arranged. In this way, the punctured fluid line segments 25, 26 together with the body, for example 9, which surrounds the fluid line segments like a matrix, can be separated from the rest of the fluid line system via ball valve quick-action couplings 27 and can be replaced by new fluid line segments together with the body.

[0041] Such a modular design also facilitates re-venting after the puncture site has been replaced and limits or reduces to a minimum the amount of consumables required when using the resuscitation dummy according to the solution.

[0042] For user-friendly handling and a positionally fixed locking of the quick-action couplings 27 as well as the associated fixed positioning of the puncturable fluid line segments 25, 26, the quick couplings 27 are fixed inside the dummy body 1 by means of corresponding holders 28.

[0043] In a preferred embodiment, the resuscitation dummy provides an elastic fluid reservoir 29 on the side of the venous fluid line segments in order to prevent collapse of these venous fluid line segments during the use of a resuscitation aid and additionally to realise the simulation of a central venous pressure (CVP) in combination with a fluidic component 24 integrated within the additional extracorporeal circuit 23. Furthermore, this reservoir 29 is used to automatically eliminate air bubbles from the fluid system.
