[0113] Referring to
[0114] The eye treatment apparatus 10 includes a supporting platform 11 configured for holding an eye drop dispenser 23. The supporting platform 11 has a top side 111, an under side 112, and a lateral side 110 having a right wall 113, a left wall 114, an upper wall 115 and a lower wall 116. The terms top side, under side, lateral side, right wall, left wall upper wall and lower wall are used herein for the purpose of description of a relationship between the different parts of the supporting platform 11 of the eye treatment apparatus 10 and a face 21 of the patient (22 as shown in
[0115] The supporting platform 11 includes a delivery opening 12 configured for holding the eye drop dispenser 23 in the upside-down position in the delivery opening 12. The eye treatment apparatus can be used with different types of eye drop dispensers. According to an embodiment of the present invention, the eye drop dispenser 23 includes a container in the form of small cylindrical bottle 230 configured for holding medicament. Such an eye drop bottle can be of any size or shape that allows it to be placed in the delivery opening 12 of the supporting platform 11 in the upside-down position. At the top of the eye drop dispenser 23 is a nozzle 232 that extends from the cylindrical portion forming sides 231 of the dispenser 23, and allows liquid medicament to be ejected therefrom. The eye drop bottle of the dispenser 23 is usually fabricated from a pliable and resilient material, such as plastic, that allows the user to squeeze liquid from the bottle by squeezing the sides 231 of the eye drop dispenser 23 by the fingers, thus causing the medication to fall from the nozzle of the eye drop dispenser into the eye 13.
[0116] The delivery opening 12 may have different shapes to accommodate to the shape of the walls of the eye drop dispenser 23. According to the embodiment shown in
[0117] In order to provide secure grasping of the eye drop dispenser 23 within the delivery opening 12, the eye treatment apparatus 10 includes a locking mechanism 20 integrated with the supporting platform 11. According to the embodiment shown in
[0118] The ratchet mechanism 200 includes a rack plate 15 and a pawl plate 16. The rack plate 15 is an extension of the left wall 114 from the corner of the intersection of the left wall 114 with the lower wall 116, while the pawl plate 16 is an extension of the right wall 113. The rack plate 15 includes a tooth portion 152 having ratchet teeth 153 located at the inner surface 151 of the rack plate 15. On the other hand, the pawl plate 16 includes a pawl tooth 161 arranged at an end of the pawl plate 16 and configured for engagement with the ratchet teeth 153. In operation, the user inserts the eye drop dispenser 23 into the delivery opening 12 upside-down, and then bends the pawl plate 16 towards the rack plate 15 until the pawl tooth 161 at the end of the pawl plate 16 mates up with the toothed portion 152 of the rack plate 15.
[0119] According to an embodiment of the present invention, the supporting platform 11, the rack plate 15 and the pawl plate 16 are integrated together, and are formed from a light, resilient and pliable material. An acceptable material for the supporting platform 11, the rack plate 15 and the pawl plate 16, such as plastic, can, for example, be used. The rack plate 15 and the pawl plate 16 should have relatively low toughness to allow the user to bring the pawl plate 16 to the rack plate 15 by his/her fingers in order to lock the ratchet locking mechanism 13, and thereby to secure the eye drop dispenser 23 within the delivery opening 12 of the supporting platform 11 by providing a gripping force acting on the eye drop dispenser 23.

[0123] Referring to
[0124] The restricting member 500 is connected to the under side 112 of the upper, left and lower walls 115, 114 and 116 of the supporting platform 11.
[0125] Connection of the restricting member 500 to the platform 11, can for example, be made by using a suitable fastener or connector. Alternatively, the supporting platform 11 and the restricting member 500 can be manufactured as one entire part.
[0126] The restricting member 500 includes a through opening 510 having a predetermined dimension adapted to match the dimension of the nozzle 232 of the eye drop dispenser 23. The restricting member 500 is adapted to prevent direct contact of the tip of the nozzle 232 with the eye. According to the embodiment shown in
[0127] Referring to
[0128] According to an embodiment of the present invention, the upper leg 17 and the lower leg 18 are terminated in feet 171 and 181, correspondingly. When desired, the feet 171 and 181 include cushion pads. The cushion pads can, for example, be made from polyester foam or ribbon.
[0129] Preferably, but not mandatory, the feet 171 and 181 are separate elements that are pivotally attached to the ends of the upper and lower legs 17 and 18, correspondingly, for example, by using hinges (not shown). The cushion pads of the feet 171 and 181 should have surface contact area with the patient's face sufficient for the cushion pads to gently engage with the skin of the patient, and should not cause significant discomfort to the patient during eye treatment procedures. For example, the surface contact area of the cushion pads of the feet 171 and 181 can be in the range of 3 cm.sup.2 to 6 cm.sup.2.
[0130] To further facilitate the accurate administration of eye drops, the tactile surface of cushion pads of the feet 171 and 181 with the face of the patient 22 can be rough. This provision can provide desired friction between the tactile surface and the cheek 25 of the patient 22 and assist the lower leg 18 in retracting the lower eyelid so as to expose the conjunctiva. In this manner, greater control over the position of the dispenser 23 can also be maintained by the user of the apparatus 10, 100. The method of operation of the eye treatment apparatus 10, 100 is shown herein below in detail.
[0131] According to an embodiment of the present invention, the lower leg 18 includes a bending mechanism 182 located between the supporting platform 11 and the foot 181. The bending mechanism 182 allows the lower leg 18 to be bent into angular form to limited angles having predetermined values outwardly or inwardly with respect to the patient's face. As will be described herein below in detail with reference to
[0132] Referring to
[0133] The elastic member 185 can be formed as an integral part of the lower leg 18 together with the leg parts 183 and 184, as shown in

[0137] The supporting platform 11, the upper leg 17 and the lower leg 18 of the eye treatment apparatus 10, 100 can be formed from a light and pliable material. An example of a material suitable for the present invention includes, but is not limited to, plastic.
[0138] The dimensions of the supporting platform 11, the upper leg 17 and the lower leg 18, and the distance between the feet 171 and 181, is in proportion to the typical dimensions of a human face. When desired, a set of the upper leg 17 and the lower leg 18 having various dimensions can be manufactured and used with the supporting platform 11 to match diverse face sizes of patients. These various size legs 17 and 18 may be provided separately from the supporting platform 11 in order to allow users to select the legs with the proper size, and then attach the proper size legs to the supporting platform 11. Thus, the supporting platform 11 may be available for purchase with a plurality of legs 17 and 18 having different sizes in order to accommodate a plurality of users for the same apparatus, for example, children and parents in a family.
[0139] Turning back to
[0140] The eye opening assembly 19 also includes an eyelid-retaining thread 194 stretched between the distal ends 1920 and 1930 of the frame arms 192 and 193. According to an embodiment, the eyelid-retaining thread 194 is a flexible filament having a predetermined strain that can follow an outer contour of the eyeball and conform to the shape of the eyeball when the eyelid-retaining thread 194 is placed on the upper eyelid 133 by applying a predetermined pressing force against the eye 13 along the line of contact of the eyelid-retaining thread 194 with the upper eyelid 133. For example, the predetermined pressing force can be in the range of about 0.5N (Newton) to 1.5N. Examples of materials suitable for the eyelid-retaining thread 194 include, but are not limited to, silicone, rubber and other flexible materials. According to an embodiment, the eyelid-retaining thread 194 can also be in the form of a thin coil spring.
