2709 Mondovi Road Eau Claire Wisconsin 54701 United States of America Mary M. Jurmain and John C. Fusi Spruson Ferguson St Martins Tower 31 Market Street Sydney NSW 2000 Neck Assembly for Infant Simulator The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5845c NECK ASSEMBLY FOR INFANT SIMULATOR FIELD OF THE INVENTION This invention broadly relates to the field of simulated child care.

More specifically, the invention relates to infant simulators used in educational programs for educating prospective parents about the realities of parenthood, assisting in the education and training of personnel entering the child-care profession, and assisting in the continuing education of persons working in the child-care profession.

BACKGROUND

Teen-age pregnancy is an ever increasing problem. Teen-age parents, surveyed as to why they elected to have a baby, gave such reasons as "babies are so S. cute," "I wanted attention," "I needed someone to love and love me back." Such romantic feelings toward having a baby almost never include an understanding of the responsibilities imposed by a baby, including loss of sleep, loss of freedom, the need for constant attention, etc. Attempts to educate teen-agers about the trials and tribulations of caring for an infant and raising a child using the traditional educational methods of lecture and readings are rarely successful.

•*o Some resourceful educators, realizing that traditional educational 25 methods are not working, have attempted to demonstrate the care requirements of an S infant by requiring students to carry a sack of flour, an egg or a plant throughout an assignment for a period of one to several days. While somewhat exemplary of the care requirements of an infant, such programs do not fairly represent the care requirements of an actual infant and have proven to be of limited success.

United States Patents Nos. 4,115,948 issued to Burks and 5,094,644 issued to Kelley describe dolls that will wet a diaper after being fed from a bottle.

Such dolls are not useful for educating students about the trials and tribulations of caring for an infant as the feeding and wetting cycle is under control of the user. The student, unless under constant supervision by an educator, can fee'd and change the doll on a schedule selected by the student.

United States Patents No. 4,249,338 issued to Wexler disclosed a doll which emits a crying sound when a manually operated switch is actuated. The user t must then determine which of several actions feeding, diaper changing or back S" -patting) will turn off the crying sound. While interesting as a plaything, this doll suffers from the same drawback as the "feed and wet" dolls in that activation of the •crying actuation switch is under control of the user. The student, unless under constant supervision by an educator, can activate the switch and change the doll on a schedule selected by the student.

oooA particularly useful infant simulator system for use in educating students about the care requirements of an infant is described in United States Patent No. 5,443,388 issued to Jurmain et al. and assigned to the assignee of this application.

S• 20 The infant simulator includes such usefiul features as periodically crying throughout an assignment period on a schedule which is unknown to the student, with the student S: required to take appropriate responsive action.

It is well known and understood by those who have cared for an infant that it is absolutely necessary to continuously support the head of the infant whenever the infant is held. Infants are simply incapable of supporting their own head in an upright position for several months after birth. Failure to support the head when handling an infant can result in serious injury should the head flop backward.

A number of dolls have been designed with floppy necks, including the psychotherapy doll disclosed in United States Patent No. 4,762,494 issued to Woods -3and the training doll disclosed in United States Patent No. 4,575,351 issued to Gonzalez. However, neither of these dolls provide a realistic bending of the neck, (e.g.

the neck of the doll disclosed in Gonzalez is simply pinched by a sew line to permit flopping of the head), nor do they include instrumentation to monitor and record undesirable flopping of the head.

Accordingly, there is a continuing need for an improved infant simulator suitable for use in educational programs for educating prospective parents about the realisties of parenthood, assisting in the education and training of personnel entering the child-care profession and assisting in the continuing education of persons working in the child-care profession that realistically demonstrates the head support required by infants and includes a monitoring means for allowing an educator or other instructor to ascertain whether the head has been properly supported by the student throughout an assignment period.

It is the object of the present invention to substantially overcome or at least ameliorate one or more of the above disadvantages.

.72- [R:\LIBLL]OI 0110.doc:SSL -4- SUMMARY OF THE INVENTION s Accordingly, in a first aspect, the present invention provides an infant simulator, comprising: a doll having at least a torso and a head floppily connected to the torso by a neck linkage allowing free rearward repositioning of the head relative to the torso as between an acceptable contented position and an unacceptable, harmful, rearwardly bent position; a means effective for sensing the flopped position of the head relative to the torso as between the acceptable position and the unacceptable position; and a means in communication with the head-position sensing means for generating a perceptible distress signal when the head is sensed in an unacceptable position.

•In a second aspect, the present invention provides a method of training a person S• to properly support the head of a young infant, comprising assigning the infant simulator 1described above to a person for an assignment period.

The neck assembly 12;is designed to mpovide a realistically appearing aneck as well as a realistic mnovement o.fthe head 16 reative :o the torso 14 when the head is not properly supported.

The doll 10 preferably has the aDpearac7,e ot a young infant approximately 40 to 80 cm in lenatqh azd- approximau 3 to 5 kg in weiu±mc). The doll can be sculpted to decict the skin color and f-,acial §.'-aaure of various ethnic groups including specificaily, but not exclusively, African American, Asian, Caucasian, Hispanic, and Native American.

The neck assembly 12 includes a switch 40 that is biased in an open position and closed whenever the head 16 moves a sufficient distance along the curved neck tube 22. When the switch 40 is closed, a bent-neck signal is transmitted along lead wires 42 to a central processing unit (not shown) of the sort detailed in United States Patent No. 5,443.388 issued to Jurmain et al. and assigned to the assignee of this application. The central processing unit is designed and programmed 10 to record receipt of the bent-neck signal as a bent-neck occurrence and/or (ii) communicate the bent-neck occurrence via a signal generating means capable of producing a distress signal in response to receipt of the bent-neck signal. Other data can also be recorded and/or processed by the central processing unit as desired.

When a distress signal is generated in response to receipt of a bentneck signal, the central processing unit may optionally continue the distress signal, screaming) for a predetermined period of time 10 seconds to 10 minutes), much as an infant would be expected to continue screaming and/or crying after experiencing such a traumatic event.

As shown in Figures 1-7, the neck assembly 12 includes a curved neck tube 22 having a first end 22a, a second end 22b, a smoothly curved front surface 22f, and a sharply angled rear surface 22r, (ii) a first receiving means, such as a first receiving collar 18, mounted within an opening 20 in the top of the torso 14 for retentively receiving the first end 22a of the curved neck tube 22, and (iii) a second receiving means, such as a second receiving collar 24, mounted within an opening 21 within the bottom of the head 16 for retentively receiving the second end 22b of the curved neck tube 22. The curved neck tube 22 is fixedly secured to one of the retention collars and slidably engaged to the other.

Since the head 16 and torso 14 are preferably constructed of a soft flexible material simulating the skin of an infant, the first 18 and second 24 retention collars provide the structural rigidity necessary to accommodate reciprocating movement of the head 16 relative to the torso 14.

Figures 1-7 show an embodiment in which the curved neck tube 22 is fixedly engaged to the torso 14 through the first retention collar 18 and slidably engaged to the head 16 by the second retention collar 24. The first retention collar 18 is fixedly secured to the torso 14 within the neck opening 20 and the second retention 10 collar 24 fixedly secured to the head 16 within the neck opening 21 by any suitable means including adhesive bonding, bead welding, friction fitting, sewing, stapling, etc.

The first end 22a of the curved neck tube 22 extends into the first retention collar 18 and abuts against an inner flange 23 on the first retention collar 18.

The first retention collar 18 is fixedly secured in this position by any suitable means, including adhesive bonding, thermal welding, friction fitting, a plurality of latches, a retaining ring, matched threading on the curved neck tube 22 and the first retention collar 18, snap fasteners, etc.

The second retention collar 24 is effective for sliding and/or pivoting motion along the curved neck tube 22 between an acceptable rest position, shown in Figure 6, with the head 16 and torso 14 aligned(i.e., the central longitudinal axis 100x defined by the first retention collar 18 and the central longitudinal axis 200x defined by the second retention collar 24 axially aligned), and (ii) an unacceptable bent-neck position, shown in Figure 7, with the head 16 angled backward from the torso 14 the central longitudinal axis 200x defined by the second retention collar 24 positioned at a maximum angle a relative to the central longitudinal axis 100x defined by the first retention collar 18). The neck assembly 12 allows the head 16 to initially pivot backward about pivot pins 30 relative to the torso 14 until the head 16 contacts the torso 14. Once the head 16 contacts the torso 14, the head 16 begins to move away from the torso 14 in a relatively linear fashion while continuing to pivot about the pivot pins 30 until linear motion is essentially stopped due to the sharpness of the angle at the back side 22r of the curved neck tube 22. Thereafter the head 16 continues to pivot about pivot pins 30 until the second retention collar 24 contacts an externally extending tab 26 projecting from the front side 22f of the curved neck tube 12 proximate the second end 22b of the neck tube 12. This combination of linear and pivoting movement of the head 16 relative to the torso 14 prevents the torso 14 from interfering with continued movement of the head 16 as the head 16 bends backwards and provides a realistic bending.

Movement of the second retention collar 24 along the curved neck tube 22 is governed by a guiding mechanism (unnumbered). The guiding mechanism includes a closed end channel 34 within the back surface 22r of the curved neck tube 22, (ii) a longitudinally extending finger 28 unitarily formed with the second collar 24 and extending inwardly and downwardly from the second collar 24 for slidable engagement within the channel 34, (iii) a pair of transversely opposed, longitudinally extending, closed end grooves 36 positioned on either side of the channel 34, and (iv) transversely extending pivot pins 30 extending from a distal end (unnumbered) of the finger 28 for slidable engagement within the grooves 36. The ~20 channel 34 extends from an open end (unnumbered) at the first end 22a of the curved neck tube 22 to a closed end (unnumbered) proximate a position on the curved neck tube 22 at which the curved neck tube 22 begins to curve. Similarly, the grooves 36 each extend from an open end (unnumbered) at the first end 22a of the curved neck tube 22 to a closed end (unnumbered) intermediate the ends of the channel 34. The closed end of each groove 36 is positioned relative to the pivot pins 30 so that the pivot pins 30 will slide within the grooves 36 for a defined distance as the second retention collar 24 sides along the curved neck tube 22, without contacting the closed end of the grooves 36. A notch 32 is provided in the first retention collar 18 to accommodate finger 28 when the first 18 and second 24 retention collars are aligned and positioned proximate one another in the rest position, as shown in Figure 6.

The pivot pins 30 are cooperatively engaged within the grooves 36 so as to limit the degrees of freedom within which the head 16 can move relative to the curved neck tube 22. The pivot pins 30 thereby define the axis (not shown) about which the second retention collar 24 pivots as the collar 24 moves along the curved neck tube 22, and prevents the second retention collar 24 froiwbecoming cocked relative to the curved neck tube 22 and hanging up on the tube 22.

The curved neck tube 22 may be configured to provide any desired maximum angle a before continued movement of the head 16 is prevented by stop 26.

i'.

10 A maximum angle a of approximately 600 has been found to provide a realistic effect.

The entire doll 10, including the neck assembly 12, should be sufficiently sturdy to withstand rough handling by frustrated care providers. Hence, the materials of construction and the means for attaching the various components should be selected to ensure that the doll 10 will survive such anticipated abuse.

The retention collars 18 and 24 and curved neck tube 22 may be formed from a number of suitable materials including metals, such as aluminum and steel, and plastics such as polyacrylates acrylonitrile-butadiene-styrene S* 20 terpolymers (ABS), and polyvinyl chloride (PVC).

A sensor is provided to detect positioning of the head 16 in an unacceptable flopped or bent position. Any sensor capable of reliably detecting positioning of the head 16 in a flopped position and transmitting a bent-neck signal to a central processing unit (not shown) for reporting a bent-neck occurrence by emitting a perceptible signal, such as a scream, and/or recording the bent-neck occurrence data for subsequent review by an educator or other administrator. Exemplary sensors include specifically, but not exclusively, mechanical switches such as a toggle switch, magnetic sensors, optical sensors, etc.

The sensor can be positioned so as to be actuated and sense a bent-neck occurrence at any desired angle a so long as the angle a bears at least some resemblance to the angle at-which injury is likely with an actual infant. The trip angle a, below which the head is sensed in an acceptable position and above which the head is sensed in an unacceptable position, is preferably between about 30° and 70° most preferably between about 450 and 60°. A trip angle of less than 30° c. result in false reporting of a bent-neck occurrence as such angles can be reached dur \normal safe handling of an infant, while trip angles of greater than 700 can result in hijsed reporting of a bent-neck occurrence as less severe angles are often indicative of a lack of proper head support.

A specific example of a suitable mechanical sensor is shown in Figure o.:o 2. A mechanical switch 40, connected to a central processing unit by lead wires 42, is o provided on the smoothly curved side 22f of the curved neck tube 22 proximate the second end 22b of the neck tube 22. The switch is actuated when the. head 16 reaches a flopped or bent position proximate the second end 22b of the curved neck tube 22 and sends a bent-neck signal to the central processing unit.

The head position sensor can also be configured to sense the duration 20 of a bent-neck episode, (L the length of time the head 16 remains in an unacceptable position) and transmitting such duration data to the central processing unit. The duration data may be used to establish the intensity and/or duration of the perceptible signal generated during the bent-neck episode a cry for the first two minutes followed by a piercing scream thereafter until the head 16 is returned to an acceptable position), and/or simply recorded for subsequent review by an educator or other administrator duration of each bent-neck episode occurring within an assignment period or total duration of all bent-neck episodes occurring within an assignment period).

The neck assembly 12 may also optionally be equipped with a sensor (not shown) capable of measuring the force with which the head 16 is allowed to flop from an acceptable position to an unacceptable position and transmitting such force data to the central processing unit. The force data, as with the duration data, may be used to establish the intensity and/or duration of the perceptible signal generated in response to the bent-neck occurrence a short cry for a bent-neck occurrence effected with minor force, a long loud cry for a bent-neck occrence effected with modest force, and a scream followed by an extended period of crying for a bent-neck occurrence effected with significant force), and/or simply recorded for subsequent review by an educator or other administrator.

Such force data may also be used by the central processing unit to reduce the recording of false bent-neck occurrences instances when the head 16 is properly supported but happens to reach the trip angle at a slow speed) by o.o •preventing the recording of a bent-neck occurrence, even though the head 16 reaches the trip angle and activates the position sensor 40, uniess the force exerted by the head 16 also exceeds a predetermined threshold indicative of mishandling or neglect.

Similar control on the reporting of false bent-neck occurrences can be achieved by (i) strongly biasing the toggle switch 40 away from the curved neck tube 22 to prevent tripping of the switch 40 unless the second retention collar 24 reaches the toggle switch 40 with sufficient force to overcoming the biasing force on the switch 20 and/or (ii) biasing the head 16 towards the normal rest position, such as with a spring (not shown) extending through the bore (unnumbered) of the curved neck tube 12 and connected to both the head 16 and the torso 14, wherein the force exerted by the biasing means would need to be exceeded in order for the head 16 to reach the trip angle.

Exemplary sensors include specifically, but not exclusively, linear motion rheostats or a series of binary switches actuated at different angles a. Both of these sensors would be effective for sensing and and recording or reporting acceleration of the head 16 as the head 16 moves along the curved neck tube 22.

PCT/US98/17435 The neck assembly 12 is particularly suited for use in a fully monitored infant simulator of the type disclosed in United States Patent No. 5,443,3 8 8 issued to Jurmain et al. The infant simulator of Jurmain et al. includes a central processing unit and appropriate sensors for sensing and recording a variety of data relevant to care of the infant number of crying episodes and the interval between initiation of crying and satisfaction of necessary care requirements).

Use The infant simulator 10 is used to train persons to properly support the head of a young infant by simply assigning the infant simulator 10 to the person for an assignment period, typically 24 to 72 hours.

When the infant simulator 10 is constructed and programmed to generate a distress signal in response to the sensing of a bent-neck occurrence, the person is provided with immediate feedback as to their performance in supporting the head 16 of the doll 20 When the infant simulator 10 is constructed and programmed to record bent-neck occurrence data and/or bent-neck-duration data, such data can be reviewed by an educator or other instructor at the end of the assignment period and discussed with the person to whom the doll 10 had been assigned.
