Abstract: Device for simulating variable lung compliance, comprising a structure having two main components (3, 4) between which an artificial lung (1) is situated, the main components (3, 4) being adapted to be moved away from each other by the lung (1) when the lung is inflated and are adapted to move towards one another to force air out of the lung (1) in an exhalation phase; and a biasing means (17, 18) acting to provide a force that acts to move the two main parts (3, 4) towards one another. The biasing means comprises at least one spring (17, 18), which is selectively attachable to impose the force, upon actuation by a spring holding mechanism (22, 32).

Abstract: Simulator for medical training having at least a detachable, fluid-tight hollow member comprising: at least a portion (1; 25) made of a self-sealing material; an opening (2; 17) to fill said hollow member with a fluid, said opening (2, 17) being provided with closure means (4; 26) or being connected (8) to closure means; fastening means (4,5; 28) to detachably fasten said hollow member to said simulator. The portion made of self-sealing material allows multiple punctures before having to be replaced.

Abstract: Device to be used during chest compression in connection with CPR or for training, and more particular, a device for placement between the hands of a person performing CPR and the chest of a patient or manikin. The device is adapted to emit a sound when the chest compression is performed with a force that exceeds a predetermined value and optionally also emit a sound indication the intended frequency of the chest compression. Different mechanical and electronical embodiments are described, these includes an automatic switch that turns the electronic circuit on when the device is compressed and an embodiment having different predetermined forces depending on which side of the device is facing upwards.

Abstract: A fastening device for interconnecting two parts, comprising a longitudinally variable bolt designed to be inserted through a hole in a first part and engage the edge of an opening in a second part. The bolt is further configured to rotate about an axis that runs generally transversely across the longitudinal axis of the bolt, using the edge of the opening in the second part as a sliding track. The bolt defines a spring configuration intermediary of its ends so that the bolt may be compressed in the longitudinal direction and resumes its original length when it is released. The bolt is provided with grooves at opposing ends, which grooves extend generally transversely across the longitudinal axis of the bolt and are designed to engage the edge of the opening in the second part at diametrically opposed locations.

Abstract: A dummy for practicing cardiopulmonary resuscitation (CPR) of a human being has a simulation of the thorax in the form of a torso, a head simulation and a trachea/lungs simulation in the form of a bag. The thorax simulation formed by the torso is made of an elastically compressively deformable foam and further includes a chest plate accommodated under the chest side of the torso. The back of the torso is shaped to provide support bodies, such that compressive deformation of the foam of the torso and flexural deformation of the chest plate upon compression in the context of cardiac massage jointly simulate the natural deformation of a human thorax. That design can allow the dummy to be economically produced in spite of a realistic simulation and natural deformation characteristics.

Abstract: A dummy for practicing cardiopulmonary resuscitation (CPR) of a human being comprising a simulation of the thorax and the head and a lungs simulation in the form of a bag which can be inflated through the mouth or nose opening of the head. The thorax is formed by a hollow body of plastic material, which is in air exchange relationship with the atmosphere and which has stiffening ribs which reproduce approximately human ribs. In that arrangement the number and size of the stiffening ribs are so selected that the compressibility and return force of the thorax correspond to those of a human thorax not only in regard to extent but also in terms of their nature and form, and thus provide a particularly good approximation to the behavior of a human thorax.
