  This invention relates to education appara-
  tus for teaching, by means of demonstration, the
  approved practice of obstetrics.
  There are many sections of the country in
  which modern knowledge and procedure in the 5
  practice of obstetrics is not wide spread, but in
  which, on the contrary, the majority of child
  births are entrusted to midwives whose training
  is limited to that acquired through experience.
  It is upon the supposition that the older the mid- 10
  wife the more experience she has, that the more
  elderly midwives have gained a prestige over the
  younger members of the group, so that they
  bring to the childbed traditional practices which
  do not make sense, and some of which are posi- 15
  tively detrimental to the welfare of mother and 
  child .
  The practice is reflected in the statistics which 
  show that in those places where the practice of
  obstetrics is for the most part left to unlicensed 20
  midwives with no standard of qualifications, the
  mortality rate of mothers, as well as new born
  babies, is much greater than in the more favored
  sections where hospitalization and scientific
  technique are the customary resort. 25
  State agencies endeavoring to raise the stand-
  ard of obstetrical qualifications are confronted
  with the alternative of refusing to license the
  great bulk of midwives, or of offering them as a
  condition to eligibility for a license, a short course 30
  in the only practical method of training that is
  adapted to their very limited educational status,
  that is, by a system of demonstration. The first
  alternative is impractical, since there are not
  enough qualified nurses to go around, and in the 35
  hinterlands where the need for improved knowl-
  edge and methods is greatest, the people would
  resort to the midwives, licensed or not.
  The present invention represents one of the
  correlated phases in a system of instruction by 40
  means of which a qualified instructor can demon-
  strate to a class of limited literacy, in an interest-
  ing and easily understood manner, the phenom-
  ena of parturition and the procedures required in 
  a normal delivery, as well as the more common 45
  exigencies of birth encountered sooner or later in
  the experience of the midwife. The system com-
  prises these elements, employed singly and in
  combination.
  (a) The mother manikin. 50
  (b) The fetus doll.
  (c) The placenta, per se, or in combination
  with the fetus.
  Said three elements or features are disclosed
  In my pending application Serial Number 135,156, 55
  [right column]
  filed December 27, 1949. The present application
  covers the mother manikin, and is a divisional ap-
  placation, out of said pending application, by offi-
  cial requirement.
  One of the objects of the invention is to provide
  a mother manikin substantially full size, having
  an abdominal cavity open at the front, selectively
  closable by one of three ventral covers of dif-
  ferent degrees of convexity, copied from nature,
  representing the shape at the three trimestral
  periods of pregnancy, by means of which the mid-
  wife can learn to judge by observation how far
  the gestation period has run, in the examination
  of her patients.
  Another object of the invention is to provide
  a mother manikin as described, in which the ad-
  dominal cavity is sufficiently capacious to enable
  the instructor using a full size flexible jointed
  fetus doll to demonstrate the several positions
  which the fetus may occupy in the abdomen at
  the time of delivery. 
  Still another object of the invention is to pro-
  vide the mother manikin with a flexible and ex-
  pansible vagina forming a wall of the abdominal
  cavity, sufficiently large to permit the fetus doll
  to pass through it.
  Another object of the invention is to make the
  mother manikin with jointed head and limbs so
  that various positions assumed by the mother
  can be demonstrated, such as the knee-chest at-
  titude, useful in retarding delivery. 
  Other objects of the invention will appear as
  the following description of a preferred and 
  practical embodiment thereof proceeds.
  In the drawings throughout the figures of
  which the same reference characters have been
  used to denotes the same part:
  Figure 1 is a front elevation of the mother
  manikin.
  Figure 2 is a side elevation, partly in section.
  Referring now in detail to the figures, the
  numeral I represents the mother manikin as a 
  whole, which preferably has the size and gen-
  eral likeness of an actual woman, the head, arms
  and legs being preferably jointed, as shown, so
  that the manikin can be made to assume various
  positions of which the human body is capable.
  The manikin may be made of any suitable ma-
  terial such as papier-mache, plastic, etc., and may
  be covered with a skin in appearance and to the
  touch.
  The manikin I is provided with an abdominal
  cavity 2, which opens in the ventral surface of
  the body, and which is sufficiently capacious to
