A 3-in-1 commode is a type of bedside commode that can be used in three different ways. It is designed to serve as a portable toilet, a raised toilet seat, and a toilet safety frame. The three functions of a 3-in-1 commode are: 

1. Portable toilet: The 3-in-1 commode can be used as a standalone toilet with a seat, bucket, and lid. This allows the commode to be used in a variety of settings, such as in a bedroom, living room, or other areas of the home where a bathroom is not easily accessible. 

1. Raised toilet seat: The 3-in-1 commode can also be used as a raised toilet seat. By placing the commode over a standard toilet, the patient can use it as a raised seat that makes it easier to get on and off the toilet. 

1. Toilet safety frame: The 3-in-1 commode can also be used as a toilet safety frame. By placing the commode over a standard toilet, the patient can use the arms of the commode as a support while getting on and off the toilet, providing extra stability and safety. 

The 3-in-1 commode is a versatile and convenient piece of medical equipment that can be used in a variety of settings and situations. It is often used by patients who have mobility or balance issues and need extra support and stability when using the toilet.
