Iron is a mineral found in every cell of the body. Iron is considered as an essential mineral because it is needed to make part of blood cells. The human body needs iron to make the oxygen-carrying proteins hemoglobin and myoglobin. Hemoglobin is found in red blood cells and myoglobin is found in muscles. Iron also makes up part of many proteins in the body.

Iron Supplements are supplements used in medicine to treat iron-deficiency anemia. Iron is very important for the production of hemoglobin in the blood and for supplying oxygen to red blood cells. Iron supplements are used to treat iron deficiencies.

An irrigating cannula is used to irrigate under the flap, wash out any interface debris, and float the flap into the correct position. The diameter of the cannula can range from gauge 26 to 30 and the length and angulation can be variable depending on the designer and manufacturer. Some cannulas have spatulated or flattened tips to allow for easy insertion underneath the LASIK flap. Other innovations are side ports or multiple openings for diffuse irrigation and effective floating of the flap.

Irrigating solutions are intended for such purposes as irrigating wounds, moistening dressings, and cleaning surgical instruments. It is used in the dialysis of patients with such disorders as renal failure, poisoning, and electrolyte disturbances. It removes waste materials, serum electrolytes, and toxic products from the body.

Irrigation/Aspiration systems vent a portion of an aspiration circuit by drawing sterile air from a bag. The bag is provided with an air reservoir member to ensure that an adequate air volume is available.

Ishihara color blindness test chart is a simple and accurate way to determine congenital, complete, and incomplete color blindness. The charts include four special plates to determine the kind and degree of the defect in color vision. The plates are encased in a specially designed album-type book for ease of handling. Each book includes instructions.

The Ishihara color plate is a formal measure that screens for color deficiencies by asking the patient to identify numbers or symbols or follow a winding line embedded in a patterned background.

Ishihara seudoisochromatic plate is the most common clinical test for colorblindness. Most ishihara test plates are pointillist circles containing an Arabic numeral, which should be visible (if a little eye-popping) to a normal viewer, but only weakly visible or invisible to a colorblind individual.

Island Dressings is a family of wound dressings that are bordered by adhesive. They consist of an absorbent pad surrounded by a medical adhesive. Island dressings provide post-operative protection for acute surgical incisions. Island dressings absorb excess wound fluid and maintain a sterile environment & provide a protective barrier against further trauma. The island dressings moisture control construction help create the wound healing environment essential for the healing of pressure ulcers, surgical incisions and partial & full thickness wounds. Island dressings are used in stoma care and in patches for transdermal administration of active agents.
