# 5. General Description

The CLINITRON® RITE•HITE™ Air Fluidized Therapy Unit combines the best features of the predicate devices, CLINITRON ELEXIS® (K943385) and the CLINITRON AT•HOME® (K942184), in order to meet the design objectives. The intent of the design is to provide an economical combinational therapeutic support surface on a mobile articulating frame specifically for use in the Long Term Care setting. Another design objective was to provide this type of surface on a frame that would go as low as possible. The CLINITRON® RITE•HITE™ tank edge is at 21.5 inches in its lowest position. This will permit easier positioning and egress.

The combinational support surface includes both low airloss and air fluidized therapies. The upper half delivers low air loss therapy through low-friction support cushions which supports the upper half of the body (above the waist) and the lower half consists of air fluidized therapy which supports the lower half of the body (below the waist). This type of sleep surface is common to both the CLINITRON ELEXIS® and the CLINITRON AT•HOME®.

The CLINITRON® RITE•HITE™ Air Fluidized Therapy is intended for medical purposes to treat or prevent bedsores, to treat severe or extensive burns, or to aid in circulation. This bed will be an ideal support for patients who have advanced pressure ulcers, flaps, grafts, or burns, and require frequent transfers or variable head elevation and any other conditions appropriate for air-fluidized therapy. The bed also can be used for intractable pain, extensive epidermal detachment, Stevens-Johnson Syndrome, purpura fulminans, aid in infection control, induce relaxation which may reduce need for sedative and pain medication, improve patient outcome, and reduce wound healing time. The bed will permit easy positioning and egress, thereby enhancing the independence of residents.

# 5 Safety and Efficacy

The safety characteristics of this product compare to those of the predicate devices. No significant changes have been made which impact the safety and efficacy of the CLINITRON® RITE•HITE™ Air Fluidized Therapy Unit as compared to the predicate devices. There are no performance standards established for this classification.

# 6 Technological Characteristics

The air fluidization medium consists of silicon-coated glass microspheres. The microspheres sit on top of a diffuser board and are contained on the sides by an air wall bladder/cushion. An air permeable filter sheet separates the microspheres from the patient.

Pressurized air is delivered to the chamber under the diffuser board. Air enters the chamber, passes through the diffuser board, fluidizes the microspheres, and escapes through the filter sheet. Air to the chamber is heated or cooled as necessary.

A microprocessor controls the user's operations and controls and monitors the main components of the unit.

# C. Manufacturer's Statement of Substantial Equivalence

## 1. Substantially Equivalent Devices

The CLINITRON® RITE• HITE™ Air Fluidized Therapy unit is substantially equivalent to the following device:

The CLINITRON ELEXIS® Air Fluidized Therapy Unit (Model C-10) manufactured by Hill-Rom, Inc.
Classification number: INX (21 CFR Part 890.5160)
510 (k) #K914351

The CLINITRON® AT• HOME™ Air Fluidized Therapy Unit (Model C-6) Manufactured by Hill-Rom®, Inc.
Classification number: INX (21CFR Part 890.5160)
510(k) # K942184

## 2. Device Similarities

The subject device is substantially equivalent to the predicate device in the following aspects:

The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and the CLINITRON ELEXIS® provide a pressure relieving sleep surface for patients who need pressure ulcer treatment. Both devices are also of benefit to patients with other serious wounds such as post-surgical flaps.

The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and the CLINITRON ELEXIS® therapy units provide a pressure relieving sleep surface. Air fluidized therapy is used in the lower section; the vast majority of pressure ulcers occur from the waist to the heels.

Like the CLINITRON ELEXIS® and the CLINITRON® AT• HOME™, the CLINITRON® RITE• HITE™ unit fluidizes microspheres by passing pressurized air through a permeable diffuser board. The same microspheres, filter sheet fabric, and similar closure systems are used in both models.

The CLINITRON® RITE• HITE™ device uses cushions to provide a pressure relieving head section like the CLINITRON ELEXIS® and the CLINITRON® AT• HOME™. The cushion section of all the models allows an articulable head which assists with activities of daily living (feeding, reading, watching

{3}

television, etc.). The soft air wall, which is a feature of all three products, facilitates patient egress.

The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and CLINITRON ELEXIS® products have air cushions organized into zones which are continuously monitored to adjust the pressures when the patient reposition themselves or when the angle of head elevation is changed.

The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and CLINITRON ELEXIS® Therapy Units use identical cushion material and construction.

The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and CLINITRON ELEXIS® are operated and controlled by a microprocessor. The microprocessor allows the products to provide the caregiver with easy to operate functions and read-outs. The microprocessor allows constant monitoring and feedback for readjustments and servicing.

3. Device Differences

The predicate device differs in the following aspects:

The CLINITRON® RITE• HITE™ Air Fluidized Therapy unit has been designed for use and servicing in a long term care environment. The CLINITRON RITE HITE has operator controls which are appropriate for long term caregivers and the environment.

The CLINITRON ELEXIS® was designed as an acute care, hospital product with features suitable for use in an intensive care unit (ICU) and operation by trained medical personnel. Acute Care features found on the CLINITRON ELEXIS® but not on the CLINITRON® RITE• HITE™ include: CPR function which automatically deflates the cushions and lowers the head and frame; radiotranslucent plate and film tray for taking X-rays without removing patient from the bed; built-in scale for weighing patient; trendelenburg/reverse trendelenburg; oxygen tank holder.

The CLINITRON® AT• HOME™ unit makes use of new materials to create a light weight frame which can be easily transported and reassembled. The CLINITRON ELEXIS® has a frame constructed of steel and is transported on integral casters. The steel frame construction of the CLINITRON ELEXIS® permits the unit to have a high/low feature which raises the entire bed up and down. The CLINITRON® RITE•HITE™ uses the frame construction of the CLINITRON ELEXIS®, but is modified to provide a lower low position.

{4}

The CLINITRON® AT• HOME™ has a base with a wide footprint which distributes the weight of the unit across a large surface area. The combined weight reduction and wide footprint alleviates the concern for the structural integrity of older homes and trailers. The CLINITRON® RITE• HITE™ is not intended for use in homes, rather medical facilities.

The CLINITRON® RITE• HITE™ unit has a remote control with large head up/down buttons compared to the CLINITRON ELEXIS® unit which has smaller head up/down buttons built into the siderails. The large buttons on the CLINITRON® RITE•HITE™ remote control are easy for the elderly or disabled to operate.

The control panel of the CLINITRON® RITE• HITE™ has fewer functions and is much easier to understand than the CLINITRON ELEXIS®. Because the CLINITRON ELEXIS® Therapy Unit has more functions than the CLINITRON® RITE• HITE™, all corresponding hardware and software is more complicated.

In the event of a mechanical or electrical failure, the CLINITRON® AT• HOME™ unit shuts down, an audible alarm sounds, and a message shows on the control panel.

The CLINITRON ELEXIS® and the CLINITRON® RITE• HITE™, in the event of a failure, show a specific error message on the display screen and sounds an alarm. With the, the alarm can be silenced by pushing a button since trained medical personnel are taking responsibility for the patient and notifying Hill-Rom of the need for service.

The CLINITRON® RITE• HITE™ unit has four removable, siderails with a sliding bar locking mechanism. The CLINITRON ELEXIS® has four non-removable, collapsible siderails which lock in place by a spring loaded latch.

The CLINITRON® AT• HOME™ unit has a folding cover under the head assembly (similar to the hood of a baby carriage) to keep the family from misusing the area for storage or allowing pets to sleep on top of the base. The CLINITRON® RITE• HITE™ being an institutional product, does not require this feature.

Although these differences provide servicing and user benefits, none of the differences adversely affects the safety or efficacy of the device.
