## Abstract

A device and method for removing residual water from the external ear canal of an individual comprise using a portion of dry, pre-compressed, absorbent sponge material that is die-cut or otherwise fashioned to have a bluntly pointed tip on at least one end. The bluntly pointed tip is placed into the external ear canal of an individual, and this bluntly pointed tip is held in place until there is visible and/or tactile evidence of water absorption by the sponge material, as indicated by swelling and/or softening of the bluntly pointed tip. These steps may be repeated as necessary to remove further residual water from the individual's ear canal.

## Claims

### Claim 1

A method for removing residual water from the external ear canal of an individual, comprising the steps of:
a. providing a device having a bluntly pointed tip on at least one end, wherein at least the bluntly pointed tip is comprised of a dry, pre-compressed, absorbent sponge material of a size and shape able to fit into the proximal portion of the external ear canal;
b. placing said bluntly pointed tip into the external ear canal of an individual, said bluntly pointed tip retaining its size and shape until coming into contact with water in the external ear canal;
c. holding said bluntly pointed tip in place until there is visible and/or tactile evidence of water absorption by the sponge material, as indicated by swelling and softening of said bluntly pointed tip; and
d. withdrawing said bluntly pointed tip from the external ear canal of the individual.

### Claim 2

The method of 1, wherein the sponge material is comprised of a cellulosic material.

### Claim 3

The method of 1, wherein the sponge material is comprised of a polyvinyl alcohol material.

### Claim 4

The method of 1, wherein the sponge material is comprised of a polyester material.

### Claim 5

The method of 1, wherein the sponge material is comprised of a low-density polyether material.

### Claim 6

The method of 1, wherein the sponge material is comprised of a polyvinyl acetal material.

### Claim 7

The method of 1, wherein the device comprises a bluntly pointed tip on both ends of the device, wherein at least both of the bluntly pointed tips is comprised of dry, pre-compressed absorbent sponge material.

### Claim 8 (depends on 1)

The method claim 1, wherein steps “a” through “d” are repeated one or more times as necessary to remove further residual water from the individual's ear canal.

### Claim 9

A device for removing water or other liquid from the external ear canal of a person or animal, comprising:
a. a portion of dry, pre-compressed, absorbent sponge material that is die-cut or otherwise fashioned to have a bluntly pointed tip on at least one end,
b. said bluntly pointed tip being of a size and shape able to fit into the proximal portion of the external ear canal, and
c. said dry, pre-compressed, absorbent sponge material being able to absorb and hold water as evidenced by visible swelling and tactile softening of the sponge material only after contact with water in the ear canal.

### Claim 10

The device of 9, wherein the dry, pre-compressed absorbent sponge material is double ended in that it has a bluntly pointed tip on both ends of the device.

### Claim 11

The device of 9, wherein the sponge material is comprised of a cellulosic material.

### Claim 12

The device of 9, wherein the sponge material is comprised of a polyvinyl alcohol material.

### Claim 13

The device of 9, wherein the sponge material is comprised of a polyester material.

### Claim 14

The device of 9, wherein the sponge material is comprised of a low-density polyether material.

### Claim 15

The device of 9, wherein the sponge material is comprised of a polyvinyl acetal material.
