Intended Use

The Inflatable Positioning Cushion device is intended to be used on nuclear imaging tables for Scintimammography procedures. The Inflatable Positioning Cushion allows for comfortable, anatomically correct, prone positioning of the patient during Scintimammography.

Device Story

Inflatable Positioning Cushion designed for use on standard nuclear imaging tables (e.g., SPECT tables). Device consists of head, abdominal, and lower body sections containing foam and inflatable cushions. Secured to table via Velcro and inflatable straps; external blower unit provides inflation. Used in clinical nuclear medicine settings to facilitate comfortable, anatomically correct prone patient positioning during Scintimammography. By stabilizing the patient and providing proper anatomical alignment, the device helps maintain position, potentially reducing motion artifacts and improving image quality. Operated by clinical staff.

Clinical Evidence

No clinical data provided for this specific device. The document references a clinical study conducted by the University of Montreal regarding the sensitivity and specificity of 99mTc-sestamibi scintimammography, but this is cited in relation to a separate Scintimammography Prone Breast Cushion product, not the subject Inflatable Positioning Cushions.

Technological Characteristics

Materials include foam cushions, inflatable cushions, and nylon/vinyl covers. Features Velcro and inflatable straps for table attachment. Includes an external blower unit for inflation. Designed for standard nuclear imaging tables (e.g., 80" x 14" cradle). Non-electronic, mechanical positioning support.

Indications for Use

Indicated for patients undergoing Scintimammography procedures requiring prone positioning on nuclear imaging tables.

The text is arranged in two lines, with "20 new replacement" on the first line and "table pads!" on the second line. The font is bold and sans-serif, and the text is centered in the image.

- · Substantially reduces lower back pain during long procedures!
- Helps reduce patient movement—you work faster!
- Radiolucent and artifact free

20am represents a unique breakthrough in pressure distribution! Immobilized patients often experience lower back discomfort and painful pressure during long procedures, such as cardiac cath, angiographies and hypertensive IVPs. The lumbar region is not supported well by ordinary table pads. Patients react by moving to relieve the pain and pressure-blurring images and complicating procedures. T-Foam precisely molds to each patient's contours to provide a total contact resting surface-eliminating lower back discomfort and painful pressure. Patient comfort soars. Procedures are completed quickly and efficiently.

Image /page/1/Picture/6 description: The image shows an advertisement for T-Foam. The text in the advertisement says "T-Foam fits every need in Imaging". The background of the advertisement is dark and blurry, but it appears to be a medical image.

Image /page/1/Picture/7 description: The image shows a comparison of pressure distribution with and without a T-Foam Pad. The top half of the image shows dangerous high-pressure peaks, while the bottom half shows safe, distributed pressure with the T-Foam Pad. The text indicates that the T-Foam Pad helps to reduce peak pressure safely.

T-Foam pads are radiolucent. They are 11/2"thick and are covered wi. blue nylon cover with water resistant seams.

Image /page/1/Figure/9 description: This image shows a variety of general-purpose T-foam pads with different dimensions and prices. The pads are labeled with codes such as #E9-213, #E9-211, #E9-210, #E91-370, #E9-677, #E9-546, #E9-545, #E920177, #E920176, #E920161, #E920162, #E920159, and #E920158. The prices range from \$299.95 to \$644.0, and the dimensions vary, including lengths like 77", 87", 75", 95", 101", 118", 79", 82", 94", and 98".
