7 Claims.

This invention relates to a device for removing particles from the surface tissue of human. eye balls and, more particularly, it relates to a resilient magnetic particle remover.

An object of this invention is to provide a magnetized particle remover of this type which is softly resilient so that it can be brought into engagement with the eye ball without danger thereto.

A further object of this invention is to provide a particle remover formed of a loop of wire and having a single strand portion for engaging the particle, the ends of the single strand being supported by coiled leg portions on opposite sides of the single strand to resiliently sup-port the single strand portion and give to it a soft touch when pressed against the eye ball.

A further object of this invention is to provide a particle remover of this type in which the ends of the legs of the loop are held firmly in engagement with a magnet bar which magnetizes the loop.

The above and other objects and features of the invention will in part be apparent and will in part be obvious from the following detailed description, and the drawing, in which:

Figure l is an exploded view partly in side elevation and partly in section showing a particle remover constructed in accordance with an embodiment of this invention, together with a cap or cover therefor;

Fig. 2 is a fragmentary, enlarged view, showing the eye-engaging strand of the particle remover and parts of the coiled legs supporting it; 7

Fig. 3 is a view in section, taken along a line III--Il1 of Fig. 2; and

Fig. 4 is a view partly in elevation and partly in section showing a particle remover constructed in accordance with another embodiment of this-;

invention.

In the following detailed description, and the drawing, like reference characters indicate like parts.

In Fig. 1 is. shown a particle remover which includes an elongated handle ID, a loop of magnetizable wire I2, a plug I3 of magnetic material, and a cap or cover I4. The plug is retained in a socket I6 at one end of the handle byan inturned lip I! at the mouth of the socket.

The wire loop I2 comprises legs I8 and I9 that are connected at their outer ends by a single strand 2!) of the wire. The legs are coiled as shown to render the loop flexible and give to the strand 2!! a soft touch or feel when applied to the surface of ones eye ball. The free ends 2 of portions 2| of the legs I8 and I9 are straight and are disposed in the handle between the socket and the magnet, the extremities of the legs being bent under the magnet at the base of the socket.

The number of turns of coil employed in the legs I8 and I9 is governed by the flexibility desired. Likewise the tightness with which the coils are wound onto each other will have its effect on the resilient softness of the loop.

The loop I2 should be made of rustless or stainless magnetic metal wire so that magnetically responsive particles are attracted to the wire.

As shown in Fig. 2, the coils of coiled portions I8 and I9 may be tightly wound so' that each coil engages adjacent coils. The coils form a path in which the magnetic flux is concentrated so that the single strand portion I8 is magnetized by magnet I3. However, when single strand portion I8 engages the eye ball, coiled portions I8 and I9 resiliently yield so that there is only a minimum pressure against the eye ball.

As shown in Fig. 1, the coils of coiled portions I8 and I9 commence adjacent the mouth of socket I6, and the coils are disposed inwardly of the end portions and extend substantially parallel to the axis of the handle I0.

Cap I4 includes a socket 22. over portions I8, I9, and 2B of the wire loop and can be seated on the end of handle III. In addition, cap I4 includes a small lens 23 which can be used for inspecting the eye ball as the magnetic single strand portion of the particle remover is brought against the eye ball and into engagement with the particle. r

In Fig. 4 another or modified form of loop is shown. The particle remover illustrated in Fig. 4 includes a handle 26 having a socket 21 in which is received a magnetic plug 28. Plug 28 holds the free ends of a wire loop 29 against'the walls of socket 21. The central portion ofthe loop is coiled transversely of the axis of handle 26, as indicated at 3|. The central portion is carried by legs 32 and 33. Free ends of legs 32 and 33 are held between plug 28 and the walls of socket 27. One coil of the coiled portion is displaced from the axis of the coil portion and is of a greater diameter than the other coils of the coiled portion to form a single strand 34. This strand is resiliently held in place by the coils of coiled portion 3 I.

The single strand portion of each particle remover of this invention can be brought into contact with the eye ball without danger of injury because the resiliently mounted coils of the single Socket 22 fits l. A device for removing magnetic particles.
