An age determination device is provided in the form of a mobile unit having a touchscreen of sufficient dimensions to enable the length of a foot of a child whose age is to be determined to be applied to the touchscreen. An onboard or separate processor is programmed to receive information representative of the measured length of a foot and to communicate with a database having data enabling a measured foot length to be correlated with a projected age of a child having the measured foot. The programming of the processor may optionally provide one or two lines on the screen capable of being manually dragged by a finger engaging the touchscreen to positions corresponding to an extremity of the heel or an extremity of the longest toe of a foot being measured. An optional retractable measuring element may physically measure the length of a foot from a device edge.

Description

AGE DETERMINATION DEVICE
CROSS-REFERENCE(S) TO RELATED APPLICATIONS
This application claims priority from South African provisional patent application number 2015/02399 effectively filed on 10th August 2015, which is incorporated by reference herein. FIELD OF THE INVENTION
This invention relates to an age determination device that can be applied to the determination of the gestational age of an unborn child; the gestational age / postnatal age of neonates; and the ages of older children up to puberty.
BACKGROUND TO THE INVENTION
Correct dating of pregnancies is important in the fields of obstetrics, neonatology, and pathology. In the case of pregnancies that are to be terminated, correct dating reduces risks of inappropriate abortion procedures and determines the type of abortion techniques that may be used. Abortion techniques change as gestational age advances.
A variety of different methods of determining gestational age includes last menstrual period (LMP) that is not a consistently valid predictor of gestational age, and most abortion providers confirm or determine gestational age by ultrasonography.
In the second trimester, biparietal diameter (BPD) has been shown to be a reliable single measurement for estimating gestational age. The Ballard Score is often used for gestational age determination in newly born infants from 26 weeks to 44 weeks whilst the New Ballard Score is an extension thereof to include extremely preterm babies as young as 20 weeks.
It is, nevertheless, common practice for physicians to confirm dating after pregnancy termination by measuring the fetal foot length. Obstetricians, neonatologists, and pathologists use foot length tables not only for quality assessment of ultrasound dating, but also to determine gestational age. Gestational age determination in neonates can be invaluable, especially in emergency situations, for example to determine medical doses of drugs and revival procedures that may be dependent on the age of a child, at least to some extent. Emergency clinical parameters for resuscitation according to age bracket of a child may be implemented if the age of the child can be estimated if it is not known.
Foot length and weight estimation can be used to determine age by using algorithms and tables.
There is a need for a device that can be more readily used by medical personnel and other healthcare workers to estimate gestational age, ages of neonates and the ages of young children possibly up to the age of puberty.
SUMMARY OF THE INVENTION In accordance with this invention there is provided an age determination device comprising a mobile unit having a touchscreen of sufficient dimensions to enable the length of a foot of a child whose age is to be determined to be applied to the touchscreen, an onboard or separate processor programmed to receive information representative of the measured length of a foot and to communicate with a database having data enabling a measured foot length to be correlated with a projected age of a child having the measured foot.
Further features of the invention provide for the programming of the processor to provide an output in the form of a line shown on the touchscreen such that the line is capable of being manually dragged by a finger engaging the touchscreen to positions corresponding to an extremity of the heel or an extremity of the longest toe of a foot the length of which is being measured; and for there to be two such lines that can each be moved by a finger engaging the touchscreen to positions corresponding to both an extremity of the heel and an extremity of the longest toe in order to measure the length of the foot. Still further features of the invention provide for the mobile unit to have at least one alternative foot length input facility that may be a retractable measuring element that can be used for physically measuring the length of a foot, for example from an edge of the mobile unit to a free end of the retractable measuring element with the mobile unit optionally being configured to automatically detect the degree of extension of the retractable measuring element in order to automatically reflect a foot length when receiving a signal to do so; in the alternative, or in addition, for the mobile unit to have a keyboard input facility that may be either a hardware keyboard or a virtual touch screen type of keyboard that can be selected for display on the touchscreen in any suitable manner; in the alternative, or in addition, for the mobile unit to have an input for association with an ultrasonic device configured to be capable of measuring the foot length of an unborn child for input into the processor; and for the mobile unit to be either a custom made unit for the particular purpose or, alternatively, for the mobile unit to be a handheld device such as a conventional cellular telephone, a smart phone, a tablet computer or other touchscreen handheld device that has been programmed to form a part of the age determination device of the invention, typically by means of an age determination application installed in the mobile unit.
Insofar as the determination of age is concerned, it should be noted that there may be a difference in the correlation between age and foot length in the case of males and females and also according to racial differences, that is to say there may be a difference between Caucasians, Asians and Africans.
The preceding discussion of the background to the invention is intended only to facilitate an understanding of the present invention. It should be appreciated that the discussion is not an acknowledgment or admission that any of the material referred to was part of the common general knowledge in the art as at the priority date of the application.
In order that the invention may be more fully understood an extended description thereof follows with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
Figure 1 is a schematic illustration of one embodiment of the invention in which the age determination device of the invention is a self-contained unit;
Figure 2 is a similar illustration of an alternative embodiment of the invention in which data containing information as to the length of a child's foot is transferred to a central computer in turn arranged to interrogate a database;
Figure 3 illustrates a footprint of a child that corresponds to a flat-footed condition; and,
Figure 4 illustrates a footprint of a child that corresponds to a high arch condition of the foot. DETAILED DESCRIPTION WITH REFERENCE TO THE DRAWINGS
In the embodiment of the invention that is depicted in Figure 1 , a stand-alone age determination device (1 ) is in the form of a mobile unit having a touchscreen (2) of sufficient dimensions to enable the length of a foot of a child whose age is to be determined to be accommodated within the area of the touchscreen as indicated by the footprint (3) in Figure 1 . The touchscreen may be especially embodied in the mobile unit on the mobile unit may be an off the shelf item selected from a cellular telephone, a smart phone, and a tablet computer. In any event, the mobile unit has an onboard processor (4) programmed to receive information representative of the measured length of a foot and to communicate with a database (5) having data enabling a measured foot length to be correlated with a projected age of a child having the measured foot.
Depending on the sensitivity of the touchscreen and its general characteristics, it may be arranged to give a correct foot length simply by contact with the foot in spite of the fact that the toes and heel curve upwardly away from the touchscreen toward their extremities. In the event that such curvature needs compensation, this can be applied automatically on the basis of predetermined values or correction factors represented by data within the database so that representative foot length is obtained for correlation with the data held in the database as regards projected age of a child having a particular foot length. Repeated measurements can be allowed and the average of multiple measurements, such as from 3 to 5 measurements may be calculated.
The software program may include a loop which transfers the foot length measurement, typically in mm, which is correlated with a reference range of age or gestation, and a feedback loop displaying the measured foot length and probable gestation can also be used for pediatric age estimation.
The possible difficulty of inaccurate sensing of the foot length can be avoided in other ways as well. One way is to include programming of the processor to provide an output in the form of a pair of lines (7) shown on the touchscreen with each line being capable of being manually dragged by a finger engaging the line on the touchscreen to positions corresponding to an extremity of the heel and an extremity of the longest toe of the foot the length of which is being measured.
Alternatively, a laser pointer measurement tool may be included for children who can stand and an additional plate may be provided for placing at a foot to measure the foot of a baby that only lies down.
A still further alternative foot length input facility may be a retractable measuring element (8) that can be used for physically measuring the length of a foot for example from either a proximal or distal edge (9) of the mobile unit to a free end (1 1 ) of the retractable measuring element. The mobile unit may optionally being configured to automatically detect the degree of extension of the retractable measuring element in order to automatically record and reflect a foot length when receiving a signal to do so, such as touching of the touchscreen in an allocated area (12).
A still further additional input facility is for the mobile unit to have a keyboard input facility that may be either a hardware keyboard or, as illustrated in the left hand side of Figure 1 , a virtual touch screen type of keyboard (15) that can be selected for display on the touchscreen in any suitable manner.
Of course, the mobile unit may have an input for association with an ultrasonic device (16) configured to be capable of measuring the foot length of an unborn child for input into the processor of the mobile unit typically by way of the keyboard. The mobile unit, as indicated above, may be a stand-alone unit that is either a custom made unit for the particular purpose or, alternatively, a conventional cellular telephone, smart phone, tablet computer or other touchscreen device that has been programmed, typically by installing a dedicated application and optionally also any required data to form an age determination device of the invention.
On the other hand, as illustrated in Figure 2, a mobile unit (21 ) having a touch-screen may be configured to transfer data embodying a foot length measurement to a remote computer (22) either wirelessly or by way of a local or public network including the Internet. The latter may be considered to be appropriate for an age determination device for hospital or clinic use but the stand-alone age determination device that may be created by installing an application in a smartphone, computer tablet or the like would be considerably more suitable for doctors and medical personnel who are on the move and need to attend patients at an accident scene or the like.
It is to be noted that the age determination device of this invention can be used for a variety of different purposes including the measurement of toe length that may be helpful in diagnosing Marfan's and other skeletal abnormalities. Foot breadth as well as foot length may also be of value in estimating weight and height of a child. If height and weight can be accurately estimated then body surface area may be an additional parameter than can be estimated that is helpful in determining medication doses for oncology & endocrinology. Furthermore, endotracheal intubation tube length can be inferred from appropriate height evaluations and thus from foot length. The touchscreen may also indicate whether the anatomical lay-out of the foot matches normal anatomy or if it is associated with a flat-footed condition, as shown in Figure 3, or a high arch condition, as shown in Figure 4. It may thus be possible to assess whether anatomical development of the foot is within normal range as a discrepancy between predicted and measured values may indicate a genetic or molecular abnormality.
The device should allow for a choice of right or left foot and may also allow for subtracting right and left foot lengths from each other for the diagnosis of conditions such as hemihypertrophy.
Foot length may also indicate the onset of puberty.
Numerous variations may be made to the implementation of the invention described above without departing from the scope hereof.
Throughout the specification and claims unless the contents requires otherwise the word 'comprise' or variations such as 'comprises' or 'comprising' will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
