Abstract
Abstract A practising apparatus for a training of resuscitation by synchronized insufflation and external heart massage in which a dummy torso is provided with an imitation thorax and imitation lungs. Writing means associated with said imitation thorax and lungs records on an advanceable record sheet the movements of the lungs and thorax in insufflation and heart massage.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
Practicing apparatus for resuscitation by synchronized insufflation and external heart massage, said apparatus comprising in combination: a. a dummy torso; b. imitation respiratory organs associated with said torso; c. an imitation thorax associated with said torso; d. a recording device adapted to receive and advance a record sheet in an advancing direction at substantially constant speed; e. writing means adapted to write on said record sheet comprising first and second independent writing instruments operable independently of each other; and f. first linkage means connecting said first writing instrument to said imitation respiratory organs to move said first writing instrument transverse to said advancing direction in response to movement of said imitation respiratory organs and second linkage means connecting said second writing instrument to said imitation thorax to move said second writing instrument transverse to said advancing direction in response to movement of said imitation thorax during insufflation and heart mAssage.
Claim 2
Dependent Claim
150 words
Practicing apparatus for resuscitation by synchronized insufflation and external heart massage, said apparatus comprising in combination: a. a dummy torso; b. imitation respiratory organs associated with said torso; c. an imitation thorax associated with said torso; d. a recording device adapted to receive and advance a record sheet in an advancing direction at substantially constant speed; e. writing means adapted to write on said record sheet comprising first and second independent writing instruments operable independently of each other; and f. first linkage means connecting said first writing instrument to said imitation respiratory organs to move said first writing instrument transverse to said advancing direction in response to movement of said imitation respiratory organs and second linkage means connecting said second writing instrument to said imitation thorax to move said second writing instrument transverse to said advancing direction in response to movement of said imitation thorax during insufflation and heart mAssage.
Claim 3
Dependent Claim
46 words
Practicing apparatus as claimed in claim 1, wherein said first and second linkage means effective to move said writing instruments each includes a mechanical coupling disposed within said dummy torso and directly executing substantially vertically directed movements occurring in the torso during insufflation and heart massage.
Claim 4
Dependent Claim
76 words
Practicing apparatus as claimed in claim 1, wherein said dummy further includes means simulating the neck region, the area surrounding the correct point of hand application when performing heart massage, a region of pulse simulation and the region where the eyelid is situated, an actuating device associated with each said simulating means, and a writing member associated with each actuating device, effective to indicate on said record sheet whether said actuating device has been correctly actuated.
Claim 5
Dependent Claim
37 words
Practicing apparatus as claimed in claim 1, and further including a rhythmic timer by means of which the reaction of the human body to resuscitation can be simulated in the manner of a predetermined variable settable program.
Claim 6
Dependent Claim
47 words
Practicing apparatus as claimed in claim 1, and further including a hollow space in said dummy torso, a closable opening through which said hollow space can be filled with a flowable material to simulate the weight of the human body, and dummy limbs attached to the torso.
Claim 7
Dependent Claim
93 words
Practicing apparatus as claimed in claim 1, wherein said imitation thorax includes a back portion of the dummy torso, a resilient element secured to said back portion and extending transversely of the torso approximately at the lower half of the sternum, and wherein said second linkage means to move said second writing instrument includes a rod connected to said resilient member for movement therewith, means for guiding the rod in the direction of heart massage pressure substantially perpendicular to said back portion said rod being connected to said resilient member for movement therewith.
Claim 8
Dependent Claim
24 words
Apparatus as claimed in claim 6, and additionally including resilient spring elements associated with said resilient member, effective to adjust the deformable characteristics thereof.
Claim 9
Dependent Claim
53 words
Practicing apparatus as claimed in claim 1, wherein said imitation respiratory organs include an inflatable pouch, two walls to said inflatable pouch, and said first linkage means includes a rod secured to one of said walls for movement therewith upon inflation of said pouch, said rod being connected to said first writing instrument.
Claim 10
Dependent Claim
25 words
Practicing apparatus as claimed in claim 8 and further including resilient means connected to said one wall of said pouch effective to resist inflation thereof.
