3. PREAMBLE TO THE DESCRIPTION
PROVISIONAL COMPLETE
The following Specification
N/A particularly describes the
nature of this invention and the
manner in which it is to be performed:
4. TECHNICAL FIELD
The present invention relates to the field of medical science and more particularly to the field of haematology wherein a set of three colour shades of nails representing and corresponding to colour-shades of the nails of women and children having hemoglobin values of 8 gm %, 11 gm % and 15gm % respectively.
This set will be used only for screening and not for estimation of haemoglobin level. It will put the screened person into normal , mild or moderate to severe anaemia group corresponding with haemoglobin values of more than 11 gms % (normal) between more than 8 gms % to 11 gms % (mild anaemia) and less than equal to 8 gms (moderate to severe anaemia).
5. BACKGROUND
At present haemoglobin is routinely estimated by taking blood from finger prick or by venous puncture. Being as an invasive technique it warrants strict observation of sterilization procedures especially with threat of HIV and Hepatitis B and Hepatitis C infections along with many other blood-borne infections.
Anaemia is one of the most common and serious problem in India among all age groups. Pregnant women and children between 6 months to 6 years are at special risk where proportion of anaemia is as high as 40-70 % in India, considering a cut-off level set by World Health Organization (WHO) for these groups at 11 gms %. Anaemia during pregnancy as well as in childhood is known to have adverse health implications including severe morbidity as well as mortality in mothers as well as babies. It is therefore, vital to detect, prevent and treat anaemia to improve the health of women and children.
Appropriate technological method for screening of anaemia by nail-shade device is a non-invasive, low cost, and easy to use by field level health workers, and fairly accurate screening method categorizing anaemia into mild and moderate to severe grades. Being non-invasive technique the risk of transmission of blood-borne diseases including HIV and Hepatitis B and Hepatitis C does not exist.
6. SUMMARY
Hence this problem is solved out by this invention. Appropriate technological method for screening of anaemia by nail-shade device is a non-invasive, low cost, and easy to use by field level health workers, and fairly accurate screening method categorizing anaemia into mild and moderate to severe grades. Being non-invasive technique the risk of transmission of blood-borne diseases including HIV and Hepatitis B Hepatitis C does not exist.
Three large sized artificial nails are fixed to three devices capable of covering tips of adult fingers and similar smaller nails are fixed to adjustable metal rings for babies. The shades of nails are selected by finding out shades of nails of persons belonging to 8 gm %, 11 gm % and 15 gm % of haemoglobin values estimated by lab life H3D premier auto mated haematology analyzer Diagnour. The shades are painted on artificial nails using paper paints, matching the shades corresponding to 8 gm %, 11 gm % and 15 gm % respectively, resulting into a set of nail-devices of three levels of haemoglobin for screening of anaemia mothers and babies separately.
These devices will be used as shown in diagrams. As seen in the diagrams the nail-shade devices are applied to flexed index finger, middle finger and little finger and shade of the nail of the person to be screened is compared to the three shades of the set of nail-shade devices. Pregnant mothers and babies can be grouped into three categories corresponding to a more than 11 gm %, as normal, between less than 11 gm % to 8 gm % as mildly anaemic and those less than 8 gm % as moderately to severely anaemic individuals by comparison of shades of nails of the person to be screened and those of set of three nail shade devices. In all cases the ring finger of left hand is recommended to be used for comparison of nail-shade as this finger is least subjected to discolouration. However, if the nail of ring finger of the subject to be screened cannot be used for screening due to problems like missing nail, discolouration, trauma, etc. any other nail can be used for the purpose of screening.

Fig. No. 1 is the front view and the back view of the set of NAIL-SHADE DEVICE FOR SCREENING DEVICE OF ANAEMIA IN PREGNANT WOMEN.
Fig. No. 2 is the front view and the back view of the set of NAIL-SHADE DEVICE FOR SCREENING DEVICE OF ANAEMIA IN YOUNG
CHILDREN.
8. DETAIL DESCRIPTION OF DRAWINGS
Fig. No. 1 is the front view of the set of NAIL-SHADE DEVICE FOR SCREENING DEVICE OF ANAEMIA IN PREGNANT WOMEN (Wl, W2 and W3) consisting of three shades matching with the colour j representing haemoglobin levels of 15 gm %, 11 gm % and 8 gm % | respectively.
The back view of this set (W4, W5 and W6) revels the snuggly fitting sleeve j of the device fitting on the finger tips of the women to be screened.
The sleeve is made of sheet metal and is open on the both sides. The angle of the cone is so adjusted that the sleeve stays on the finger tip without need of any external holding aid. Fig. No. 2 is the front view of the set of NAIL-SHADE DEVICE FOR SCREENING DEVICE OF ANAEMIA IN PREGNANT WOMEN (CI, C2 and C3) consisting of three shades matching with the colour representing haemoglobin levels of 15 gm %, 11 gm % and 8 gm % respectively.
As since the age group to be screened is from 6 months to 6 years, the fingers of the baby are very delicate and the circumference also changes very rapidly. Thus the different arrangement is adopted.
The back view of this set (C4, C5 and C6) revels snuggly fitting ring of the device fitting on the finger tips of the children to be screened. The ring is fitted with an artificial nail. Opposite to this ring is split so that the circumference could be changed easily to adjust the circumference of the finger of the baby. Once the ring is fitted on the finger tip, it stays there without any external aid.
9.1 claim:
1. The NAIL-SHADE SCREENING OF ANAEMIA IN PREGNANT WOMEN & YOUNG CHILDREN comprises of two sets of three artificial nails each of three different shades are fixed to devices capable of fixing on the finger tips of adult women and children. The different shades of the nail device used correspond to nail-shades of persons with known haemoglobin levels of 15 gm %, 11 gm % and 8 gm % respectively.
2. The NAIL-SHADE DEVICE FOR SCREENING OF ANAEMIA IN PREGNANT WOMEN & YOUNG CHILDREN is easy to use after some training to any health worker.
3. Being non-invasive technique the NAIL-SHADE DEVICE FOR SCREENING OF ANAEMIA IN PREGNANT WOMEN & YOUNG CHILDREN doesn't have risk of transmission of infections by blood borne route.
4. The NAIL-SHADE DEVICE FOR SCREENING OF ANAEMIA IN PREGNANT WOMEN & YOUNG CHILDREN is an
economical screening procedure.
5. The NAIL-SHADE DEVICE FOR SCREENING OF ANAEMIA IN PREGNANT WOMEN & YOUNG CHILDREN by reducing invasive investigations for anaemia to selected moderate to severe anaemia cases reduces the cost to the individual as well as to the health care providers.
6. The NAIL-SHADE DEVICE FOR SCREENING OF ANAEMIA IN PREGNANT WOMEN & YOUNG CHILDREN can be used for imparting health education about anaemia in the community.
