Abstract

A manikin unit (1) for teaching cardio-pulmonary resuscitation (CPR) techniques, including ventilation and external cardiac massage, comprises at least one manikin (66) and a chest extension structure (2). The manikin comprises a head (9) having a mouth opening, a neck (8), a chest means (3), a throat means in communication with the mouth opening, and a lung means in communication with the throat means, the chest means comprising a flexible front plate formed to imitate the human chest, a back plate and a resilient compression means compressed between said front plate and said back plate. According to the invention the chest extension structure (3) is connected to said chest means'"'"' distal end by means allowing it to pivot about a pivot axis extending in a direction transversely to the chest means between an in-use position wherein the chest extension structure extends longitudinally from the chest means and serves to stabilise the manikin, and a storage position wherein the chest extension structure is pivoted away from the in-use position in order to reduce the length of space occupied by the manikin unit.

Claims

1. A manikin unit for teaching cardio-pulmonary resuscitation (CPR) techniques, including ventilation and external cardiac massage, said unit being adapted for being arranged flat on a substantially horizontal surface and comprising a first manikin and a second manikin and a chest extension structure, each of said manikins respectively comprising

a head means having a mouth opening,

a neck means connected to said head means,

a throat means in communication with said mouth opening,

a lung means in communication with said throat means, and

a chest means having a proximal and a distal end and connected by said proximal end to said neck means, said chest means comprising a flexible front plate formed to imitate the human chest, a back plate and a resilient compression means arranged between said front plate and said back plate and adapted to provide a force counteracting compression of said plates,

said chest extension structure being provided with a first pivot means and a second pivot means defining, respectively, a first pivot axis and a second pivot axis, the chest means of said first manikin being pivotably connected by said first manikin chest means'"'"' distal end to said first pivot means with said first pivot axis extending in a direction transversely to said first manikin chest means, and

the chest means of said second manikin being pivotably connected by said second manikin chest means'"'"' distal end to said second pivot means with said second pivot axis extending in a direction transversely to said second manikin chest means,

whereby said first and said second chest means may pivot relative to said chest extension structure between an in-use position wherein said first and said second chest means may be arranged flat on a common, substantially horizontal surface and a storage position wherein said first and said second chest means extend generally parallel to one another.

2. A manikin unit according to claim 1, characterized by said chest extension strucure being provided with a stand adapted for supporting said chest extension structure on said substantially horizontal supporting surface.

3. A manikin unit according to claim 1, characterized by said chest extension structure further being provided with third pivot means defining a third pivot axis, a chest means of a third manikin being connected to pivot about said third pivot axis.

4. A manikin unit according to claim 1, characterized by said chest extension structure a fourth pivot axis, a chest means of a fourth manikin being connected to pivot about said fourth pivot axis.

5. A manikin unit according to claim 1, characterized by said manikin neck means being pivotably connected to said manikin chest means'"'"' proximal end and adapted to pivot between an in-use position wherein said neck means extends generally longitudinally of said manikin chest means, and a storage position wherein said manikin neck means is pivoted away from the in-use position in order to reduce the length of space occupied by said manikin unit.

6. A manikin unit according to claim 1, characterized by said manikin head means being detachable from said manikin neck means and said manikin chest means being adapted for receiving and holding said manikin head means when detached and while said manikin chest extension structure and said manikin neck means are pivoted to their respective storage positions.

7. A manikin unit according to claim 1, characterized by said chest extension structure being provided with means forming a handle adapted for being used for carrying said manikin unit while said respective chest extension structures, said respective neck means and said respective head are all arranged in their respective storage positions.

8. A manikin unit according to claim 1, characterized by said manikin chest means being adapted for securing said manikin head means and said manikin neck means when arranged in their respective storage positions.

9. A manikin unit according to claim 1, characterized by said manikin neck means being provided internally with an adapter with means for connection to a neck portion of said bag.

10. A manikin unit according to claim 1, characterized by said manikin head means comprising a pipe spigot and by said manikin neck means comprising a socket adapted for matingly receiving said pipe spigot and provided with a releasable fastener means adapted for securing said spigot in said socket to maintain the mutual engagement.
