DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to training individuals to perform cardio-pulmonary resuscitation and relates particularly to a manikin useful in providing such training.
Manikins have been used for years for training individuals to perform mouth-to-mouth artificial respiration and closed chest heart massage, known as cardiopulmonary resuscitation, or CPR, and for instruction in rescue breathing where heart failure is not a factor. In the past such manikins have been built in several pieces often including hollow shells of somewhat flexible and resilient materials, with various tubes, bellows, air bladders, valves, and pressure sensors housed within the shells. Articulation of head and neck portions has been accomplished through use of various swivel or hinge joints interconnecting separate parts. Such complexity of manikins provides some realism in the simulation of performing rescue breathing and CPR using such manikins, but is likely to add considerably to the initial cost and to the cost of maintaining such manikins.
The complexity of such previously available manikins thus makes such manikins unaffordably expensive, and thereby creates an undesirable limitation on the availability of CPR training.
It is desirable, nevertheless, to provide some feedback to a CPR student as reassurance that sufficient chest compression is being accomplished to achieve effective cardiac compression, and that sufficient air flow is being provided.
Not only is it necessary to train would-be rescuers to perform CPR on adults, but it is also necessary to train them to resuscitate infants.
What is needed, then, is a CPR training manikin, on which mouth-to-mouth rescue breathing and closed chest heart massage can be practiced, which is inexpensive, durable, easily cleaned, and low in requirements for maintenance and repairs, and which provides for practicing techniques for revival of infants.
SUMMARY OF THE INVENTION
The present invention provides a CPR training manikin which is easily manufactured, cleaned, and maintained, and which is of uncomplicated structure, yet which affords the opportunity for a trainee to practice mouth-to-mouth rescue breathing and external cardiac compression. The CPR training manikin according to one embodiment of the present invention is primarily a unitary structure of molded foam plastic material in the shape of a human torso, neck, and head. A mouth communicates with a tubular airway through which a trainee can practice mouth-to-mouth rescue breathing.
The neck portion of the manikin according to such an embodiment the invention is of a design permitting elastic flexure with application of a reasonable amount of force, simulating the effort needed to flex the neck of a living person. In a preferred embodiment of the invention the head and torso are articulated by a ball-and-socket joint permitting the head to be moved to demonstrate techniques necessary for rescue breathing.
In a preferred embodiment of the invention a restrictor is provided in the tubular airway to provide some resistance to simulate internal pressure opposing breathing into a victim in performing rescue breathing.
In a preferred embodiment of the invention the manikin is molded of micro-cellular foam plastic such as urethane, with a tough, waterproof skin portion formed in contact with the surfaces of a mold, and a core portion of lesser density contained within the skin, providing for compressibility of the torso portion of the manikin.
A preferred embodiment of the invention includes an adult-size manikin defining a cavity within its torso portion, with a second manikin representing the torso and head of an infant fitting removably within the cavity, to be removed when desired to train students in performing CPR on infants.
The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention, taken in conjunction with the accompanying drawings. dr
