Invacare Matrx Introduction (8:07 Minutes)
Hello, my name is Lois Brown and I'm the Rehab Clinical Education Specialist for Invacare. With me is Stephanie Tanguay the Clinical Education Specialist at Motion Concepts. At the beginning of 2011, Invacare and Motion Concepts integrated their seating and positioning products thus creating the Invacare Matrx Seating Positioning Line. This initiative streamlines both product lines, improves the ease of ordering product and allows single invoicing for our providers. Motion Concepts will be the center of design excellence for the seating and positioning line and will focus on improved product design, component interchangeability and improved sales and technical support. Today, we would like to take the opportunity to demonstrate the features and highlight the clinical benefits of the Invacare Matrx Seating and Positioning Line. This includes a combination of the design excellence of the Invacare and Matrx back supports and seat cushions. Ideally, a health professional should evaluate and prescribe the appropriate seating and mobility products and actual trial of the product is the best way to ensure a successful outcome. Please refer to the seating and mobility catalog for full details and the owner's manual for specific directions on the use of the equipment. The Matrx seating line has had positive acceptance in the US, Canada and abroad and has proven to be a successful product offering. We have created this short video to help you prepare to deliver an effective in service and be a trusted adviser when speaking to therapists and providers. The Invacare Matrx Hardware is highly adjustable on chair and accommodates the Matrx elite deep PB and PB deep backs thus allowing the client to trial a variety of back contour depths and back heights in the same chair. It can also be fitted to accommodate wider wheelchairs and can interface to many power wheelchairs. Earlier this year, a rolling change was made to the mounting hardware transitioning from imperial to metric sizing. During this conversion, a torque head screw was utilized as the principal type of mounting hardware. In light of industry feedback, the decision was made to phase out the use of the metric torque's hardware and switch to metric hex screws. The Invacare Matrx Back begins with the hardware. The Easy Set Hardware is designed for quick installation on chair with two-point clamp hardware, but due to its shape, it creates four points of contact for added stability. The other clear advantage is not only the four inches of depth adjustability, two inches anterior, two inches posterior of the backings, 40 degrees of back angle adjustment, 20 degrees anterior and 20 degrees posterior. There is also some rotational adjustment to accommodate for posture and symmetry. With the client in the system, you can find the appropriate depth and angle adjustment with them in the chair. It is simply a matter of tightening the bolts on each side and that sets the angle. Now, each time the back is removed and replaced it returns to that set angle so you're not depending on the client or the caregiver to line up the hardware to achieve the optimal sitting angle. A set screw will lock the hardware into place. The attachment bracket for the backings are one inch in diameter and spaces are provided to accommodate three quarters inch and seven eighth inch diameter tubing. Another advantage of the Easy Set Hardware is the ability to fine-tune the back hardware to multiple frame widths. In addition, every back is shipped with half-inch long mounting pins to fit chairs one inch wider. For example, with an 18 inch wide back, the lock knot and threaded pin can be adjusted to fit an 18-inch wide frame and a 19-inch wide frame using the longer mounting pins. Additional extended mounting pins are available for the Invacare Matrx PB and elite backs, up to 20 inches wide and 300 pounds. When adjusting the pins to fit the Easy Set Hardware, be sure to leave one-eighth inch of pin exposed on each side to allow the pins to flow in the hook to avoid undue stress to the hardware. These extended mounting pins are each one inch longer and will allow the back to fit chairs up to two inches wider. Extended range mounting hardware is available and provides one and three quarters inch additional depth adjustment in front or behind the canes. The clinical relevance is that in a client when we see disproportionate hip and chest width then we can select the optimal width of the trunk support required, especially when narrower. Split bracket hardware can be ordered instead of easy set at no charge. It has four separate attachment points. It also allows depth and angle adjustment and is still quick release. It was initially developed to accommodate various welded rigidizer bars as often times there is limited room to mount the Easy Set Hardware. Split bracket hardware also has applications in pediatrics often due to the placement of the cantilever arm at the mid thoracic for elbow, forearm placement. The hardware can be mounted anterior or posterior of the backings for seat depth and growth. Fixed Space Saver Hardware is available at no charge in lieu of Standard Easy Set. It is a solid plate, slotted the same for depth adjustment. While originally designed to mount posture and elite backs and the Motion Concepts Power Tilt on a reclined system, it is also ideal for use with severe extensor spasticity or for any application when the back support does not need to be removed, perhaps manual tilt-in space wheelchairs. There is also a mounting interface for posture and elite backs to be mounted on a formula recline or a tilt and recline. Most manufacturers only offer one set of hardware. The Easy Set Hardware, seahorse bracket comes standard in high strength composite material with a weight capacity of 300 pounds. It is also available in a heavy-duty version of solid aluminum with a weight capacity of 500 pounds.
