Recommendations on Standards for the Design of Medical Diagnostic Equipment for Adults with Disabilities, Advisory Committee Final Report

5.4.4 Transfer Support Distance from Transfer Surface Recommendations for M301 and M302

Description: This minimum distance ensures that the transfer support is within reach of the transfer surface and can be effectively used to position during a transfer. The gripping surface measurement is horizontal from the adjacent edge of the transfer surface (see figure 5.4.1).

NPRM Proposed Provision: M305.2.1 Location. Transfer supports shall be located within reach of the transfer surface and shall not obstruct transfer onto or off the surface when in position.

NPRM Preamble Discussion: The Access Board is considering whether the following technical criteria would be appropriate for the location and size of transfer supports on diagnostic equipment used by patients in a supine, prone or side-lying position, and diagnostic equipment used by patients in a seated position:

• At least one transfer support would be provided on the side of the transfer surface that is 15 inches deep minimum. The transfer support would be located on the side of the transfer surface that is opposite the transfer side (see M301.2.3 and M302.2.3) similar to the provisions in the 2004 ADA and ABA Accessibility Guidelines for grab bars provided at bathtubs and shower compartments with seats. This would be a minimum requirement. Where possible, it is recommended that supports be provided on each side of the transfer surface that is 15 inches deep minimum for patients to maintain position after they have transferred onto the equipment, and that the supports be repositionable to permit transfer.

• The transfer support would extend horizontally the entire depth of the transfer surface and would be 15 inches minimum in length.

• The gripping surface of the transfer support should be located 1 ½ inches maximum measured horizontally from the adjacent edge of the transfer surface. This would ensure that the transfer support is within reach and can be effectively used during transfers.

The above technical criteria would likely result in the transfer surface being located at the foot end of examination tables and allow the use of transfer supports similar to the side rails described in the information provided by Midmark Corporation.

The Committee recommends the transfer supports be located at a maximum distance from transfer surface of 1 ½ inches.

Rationale for the recommendation

The Committee followed the NPRM proposal.

Refer back to Figure 5.4.1 Location and Length of Transfer Supports.

5.4.4.1 Transfer Support Distance from Transfer Surface Recommendation for Stretchers

The Committee recommends locating the transfer support along the long side of the of the transfer surface on the opposite side of the transfer. The horizontal distance from transfer surface should be no more than 3 inches from the edge of the patient support surface.

Rationale for the recommendation

Currently transfer supports are part of the side rail system on stretchers. To allow the side rail system to fold and store properly, the rails must be at a little less than 3 inches beyond the mattress surface edge (transfer surface edge). The Committee proposes that this horizontal dimension be included for stretchers under the proposed rule.

5.4.4.2 Transfer Support Distance from Transfer Surface Recommendation for Imaging Equipment

The Committee recommends a maximum distance of 1 1/2 inches from the transfer surface to the support (either transfer or positioning). The distance may extend up to 3 inches where the support must fold, collapse, come off, or articulate.

Rationale for the Recommendation

The Committee decided to follow the recommended 1 1/2inch proposal but included a 3-inch dimension to accommodate movement of the support. This standard parallels the recommendation for stretchers (see Figure 5.4.1.1).
