Phototherapy eyeshield for babies

Abstract

An eyeshield (10) for protecting babies' eyesight during phototherapy treatment for neonatal jaundice includes a strap (11) of soft material sized and shaped to pass around and secured to the head of the baby. An eye pad (18) is attached or formed integrally with the strap (11). A tab (13) extending from the strap (11) adjacent to the eye pad (18) can be grasped to aid in positioning the eyeshield (10) such that the eye pad (18) lies over the baby's eyes.

Description

FIELD OF THE INVENTION

The present invention relates to eyeshields. More particularly, though not exclusively, the invention relates to a shield for protecting babies' eyesight during phototherapy treatment for neonatal jaundice.

Jaundice is the yellow discolouration of skin and tissues from the deposition in them of the fat-soluble pigment bilirubin excreted by the liver. Jaundice is not uncommon in newborn infants (pre-term or full-term) when the liver is not physiologically mature, and results from the bile produced by the liver passing into the bloodstream instead of into the intestines.

Treatment of neonatal jaundice consists of phototherapy, the exposing of the afflicted infant to visible blue light of wavelength 425-475 nm. Light of that wavelength converts the fat-soluble bilirubin into intermediary, photobilirubin isomers which are water soluble. The water-solubility of the photobilirubins enables that pigment to be excreted easily, unlike the fat-soluble bilirubin which must pass through the liver and be converted (conjugated) into the water-soluble bilirubin diglucuronide before it can be excreted.

During phototherapy treatment of jaundiced infants, it normally is desirable to place shields or shades over the eyes of the infant to protect the eyes from the blue light.

Prior art eyeshades include self-adhesive shades which are affixed to the infant's temples and are kept in place with the use of a headband attached to the eyeshade by means of fabric fasteners such as Velcro™.

Disadvantages of the known phototherapy eyeshades are that they tend to slip down away from the infant's eyes due to failure of the adhesive and the slipping of the headband, due to the infant's natural movement during sleep and waking periods.

It thus would be advantageous to have a phototherapy eyeshield which remains securely fastened over the infant's eyes, and which does not require adhesive to be placed onto the infant's skin. A further advantage is that the eyeshield should be made of an inert, absorptive fabric to minimise the build up of “sticky eye” discharge which is common in the first few days following the baby's birth.

OBJECT OF THE INVENTION

It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages and/or more generally to provide an improved eyeshield.

BRIEF DESCRIPTION OF THE DRAWINGS

A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein:

FIG. 1 is a schematic plan view of an eyeshield for infants,

FIG. 2 is a schematic inverted plan view of a portion of the eyeshield of FIG. 1 and an eye pad attachable thereto,

FIG. 3 is a schematic inverted plan view of the portion of the eyeshield shown in FIG. 2, although with the eye pad affixed in place, and

FIG. 4 is a schematic side elevational view of a baby's head with the eyeshield of FIGS. 1-3 position thereon.

DESCRIPTION OF THE PREFERRED EMBODIMENT

In the accompanying drawings there is schematic depicted an eyeshield 10. The eyeshield includes a strap 11 and a band at 12 stitched to the strap 11. Both the strap and the band are typically made of a soft material that stretches in the band length direction but does not substantially stretch in the cross band direction. Non-woven fabrics are particular suitable for this purpose. An example of such a fabric is known as “SBL” manufactured by the Kimberly Clark Corporation.

The strap 11 has a tab 13 extending from a substantially centralised portion thereof. The tab 13 is sized to be grasped between the thumb and finger of an adult. It should be noted that the strap 11 is of a sufficient length to wrap circumferential around a baby's head. One end of the strap 11 is provided with a fabric fastener 15, typically a Velcro™ fastener. The fabric fastener is designed to temporary secure to the end 16 of strap 11 in use of the eyeshield.

The band 12 also includes a tab 14 sized to be grasped between the thumb and finger of an adult.

As shown in FIG. 2, the strap 11 (shown in an inverted orientation) includes at its central portion a fabric fastening spot 17. This spot might be a Velcro™ fastener. This fastening spot might be glued, welded, stitched otherwise attached to the strap 11.

In the preferred embodiment, the strap 11 is formed of two lengths joined at a seam 19. The tab 13 might simply be formed as a pair of end portions of the respective strap portion 11 stitched together and extending upwardly from the seam 19. The purpose of the fabric spot 17 is to act as a connector by which an eye pad 18 can be temporarily secured to the strap 11. The eye pad 18 might be formed of felt or a laminate as disclosed above. The portion of the eye pad shown as a dotted circle 21 is intended to be pressed on to the fastening spot 17 in the direction indicated by arrow A. The attached configuration of the eye pad with respect to the strap 11 is depicted in FIG. 3.

In FIG. 4 there is schematically depicted in side elevation the head of a baby 20 onto which there is attached the eyeshield 10. As can be seen, the strap 11 extends about the infant's head below this occipital bulge with the eye pad 18 overlining the infant's eyes.

The band 12 extending from the strap 11 passes over the forehead of the infant. Both tabs 13 and 14 can be grasped by a person to aid in positioning the eye pad 18 over the infant's eyes and in making the overall eyeshield snugly fit the infant's head for comfort.

The infant now can be provided with the appropriate phototherapy treatment.

If the infant suffers from weeping or sticky eyes, the exudate can be absorbed by the eye pad 18 and the eye pad can be replaced by simply removing it from the fastening spot 17.

In stretching or moving the strap 11, the portions of the eye pad 18 which overlie the infant's eyes are not stretched. This is because it is only the central portion of the eye pad that is affixed to the strap 11 via the fastening spot 17.

It should be appreciated that modifications and alterations obvious to those skilled in the art enough to be considered as beyond the scope of the present invention. For example, the seam 19 and/or fastening spot 17 need not be substantially centralised along the strap 11 as it might be more desirable to provide a fabric fastener 15 which would reside to the side of the infant's head, rather than behind the head where it might press against the surface upon which the head is resting.

Furthermore, the strap 11 might be provided with two ear muffs, each of which would be position to overlie the infant's ears for protection of premature infants in incubators or infants being transported in helicopters for example.
