Elekta Connexion Table 53cm Treatment Chair, Wide Couch

Elekta Connexion™ Table 53cm Treatment Chair, Wide Couch

This versatile Treatment Chair provides upright positioning for specialty treatment cases of head, neck, thorax, breast, and lung or for patients who have difficulty lying supine for treatments.  The seated patient has improved comfort, increased lung volume and reduced respiratory motion.

The Treatment Chair has an open grid back that allows for posterior treatment of the breast, lung and thorax. Patient safety features for the treatment chair include a seat belt and a Velcro® chest belt with three vertical position locations. Patient comfort is enhanced with a vinyl covered foam seat cushion which is tapered lower at the back to prevent the patient from sliding forward and giving more support under the thigh. Velcro® tabs attached to bottom of the seat cushion make it non-slip and easily removable from the chair when installing on the treatment table.

The Treatment Chair Base attaches to the front or side of the couch. The carbon fiber couch uses four plastic blocks using t-bolts and wing nuts, or to couch rails using four plastic rail blocks specific to the couch with t-bolts and wing nuts.  The chair front is designed to be referenced to the table edge or to the table rail for reproducibility.  The chair back is then secured to the chair base with a knob. Once the chair back is secured to the base the chair back can recline to five positive-locking positions between -5°, 0° and 20° (85° to 110°).   The chair back has a carbon fiber grid treatment window with 0.007” thick polyester covering to prevent skin protrusion through the grid. Under the carbon fiber and polyester the dose rate is less than 1 mm of water equivalent build-up.

The Treatment Chair includes a Base plate with a Round Head Cup and Straps. The straps can be mounted in three different positions over the head (Forehead, Nose or Chin). The Base plate is typically mounted on the Treatment Chair Back in positions A to M. Positions N to Z are used when the Base plate is rotated 180 degrees for taller patients. A notch in the Base plate references the Base plate location on the Treatment Chair. The Base plate has two location pins and is secured to the Chair Back with a knob when the location is determined.

The Treatment Chair includes the Arms Down Assembly that consists of two stainless steel L-Bars and Arm Cradles. The L-Bar has vertical markings of 1-15 cm and slides into a locking clamp with rotation indexing of 1-12 locations. The horizontal leg of the L-Bar has 4 hole locations, A-D, for placement of the Arm Cradle. The Arm Cradle is lined with a foam pad.
