ak446 – the pump stool
The ak446 hydraulic doctor’s stool is equipped with a round seat. The stable castor cross holds five high-quality castors and provides the necessary mobility. The height is adjusted using a hydraulic pump column, which is operated with the foot. The pump handle can be swiveled through 360 degrees. The stool can be ordered with or without a backrest and armrests, which can be easily and flexibly adjusted to the desired position. Horizontally movable armrest holders allow easy navigation of the armrests with the elbows. As an option, the ak446 doctor’s stool can be fitted with pre-shaped multi-directional multi-joint armrests. This allows even finer adjustment of the forearm/hand support during an operation. The AKRUS upholstery is manufactured to a high standard and is comfortable and easy to clean. Various colors are available to choose from and allow color matching to the hospital or practice environment. The ak446 hydraulic stool is delivered fully assembled and the use of high-quality components ensures many years of reliable use when used as intended. Authorized medical technology dealers are available in the event of a service request.
