Colonic equipment types: open system -vs- closed system

There are basically two different types of equipment available for administering colonics, open systems & closed systems. There are many different manufacturers of colonic equipment, but all systems are either open or closed. Before deciding to have a colonic it is helpful to understand the basic differences between the two equipment types. It is also helpful when choosing a colon therapist to know which type of equipment they are using.

The CLOSED system:

With a closed system the client lies on a table similar to a massage table & the equipment is usually plumbed into a cabinet attached to a nearby wall. The therapist then inserts a speculum into the client's rectum & attaches one end of a disposable hose to the speculum & the other and is attached to the equipment. A pressurized stream of water is then delivered through the attached hose & into the colon. When the colon is filled & pressure reaches maximum levels the therapist manually drains the colon back through the same hose. Water pressure & temperature within the colon must be monitored constantly to avoid leakage or perforation, requiring the constant attention of the therapist. This type of system is generally the better choice for clients who have spinal injuries or other conditions causing a loss of control of the anal sphincter muscle.

The OPEN system:

With an open system the client lies on a molded fiberglass table that looks like a recliner. The form-fitted table has a basin cut into it & a small, disposable rectal tube, about the size of a pencil is attached at one end. After demonstrating to the client how to gently insert the tube, the therapist leaves the room, providing total privacy for the client. The therapist returns when the client is ready & begins a gentle, continious flow of gravity-fed water through the rectal tube & into the client. When the client feels full, they simply push out & the rectal tube automatically moves to one side within the rectum allowing the softened matter to flow out. It then flows down a drain in the bottom of the basin & past a three inch clear viewing tube. An odor exhaust system ensures the room remains odor free at all times. The therapist remains in the room & provides instruction during the first session, but private time can be provided during future sessions. This type of system is very gentle and is usually the better choice for clients who have had bowel surgery or any type of bowel disease. The open system is generally regarded as more comfortable and private than the closed system.
