A kidney dish is a kidney-shaped bowl used in medical and surgical wards to receive soiled dressings and other medical waste. Reusable kidney dishes are usually made of stainless steel, while disposable ones may be made of paper pulp or plastic. The shape of the dish allows it to be held against the patient's body to catch any falling fluids or debris.
The disposable molded pulp kidney dish is replacing the stainless steel dish because one-use-only products can decrease cross-communication of disease.
Generally, the volume of a pulp kidney dish (or "vomit dish") is 700 ml. Its length is 25cm-26 cm, its width 11 cm. Each year more than 100 million pulp kidney dishes are used in hospital or family care.
