Patent number: 5671977Abstract: An anti-thrust seating system and low profile, adjustable back system primarily intended for use in a wheelchair. The anti-thrust seating system includes a base seating member with a forward section to support the user's thighs and a rearward section to support the user's buttocks including the ischial tuberosities. The upper surfaces of the forward and rearward sections meet to form an edge extending across the base seating member. The upper surface of the rearward section has two portions which form a first step face or anti-thrust barrier to the user's ischial tuberosities. The seating system further includes at least one separate step means that can be removably positioned adjacent and rearwardly of the first step face wherein the separate step means has a second step face. The separate step means also has an upper surface which serves to effectively extend the thigh supporting surface or shell rearwardly.Type: GrantFiled: April 16, 1996Date of Patent: September 30, 1997Assignee: Jay Medical Ltd.Inventors: Eric C.

Patent number: 5511260Abstract: A mattress pad primarily intended for use with a standard hospital bed frame to reduce the development of decubitus ulcers or bed sores in patients using the pad. The pad is multi-layered and includes a cover or casing containing interior strata of a plastic film layer atop a fluid bladder layer supported on an underlying layer of foam. The pad is specially designed to reduce lateral and normal pressures and forces on the patient which can lead to the development of such ulcers. The reduction of the lateral shearing forces is accomplished in a number of ways including by oversizing the plastic film layer and fluid bladder layer on the underlying layer of foam and by positioning microbeads between the plastic film layer and fluid bladder layer to dramatically reduce the frictional drag or lateral shearing forces between the layers.Type: GrantFiled: April 18, 1994Date of Patent: April 30, 1996Assignee: RIK MedicalInventors: John C. Dinsmoor, III, Grant C. Denton, Eric C. Jay, Richard R. Runkles

Patent number: 5457833Abstract: A method for assembling a seating system by providing a base member and pad filled with fluid. The pad has a front, rear, and sides with the sides flaring outwardly of each other and of a center axis. The pad further includes an arcuate, transverse seal extending substantially from side to side across the pad and opening to face toward the front of the pad. In the method, the pad is gathered into pleats by bringing the sides toward each other until the arcuate seal assumes a substantially straight line and then positioned in its gathered state over the base member.Type: GrantFiled: August 24, 1994Date of Patent: October 17, 1995Assignee: Jay Medical Ltd.Inventor: Eric C.

Patent number: 5407248Abstract: A wheelchair back system adapted to provide a customized fit to the user. The system includes a rigid back shell removably affixed to the wheelchair, a plurality of foam blocks, and a pad member containing flowable fluid material. The back shell has a forward facing, front surface and the foam blocks are removably positionable forward of the back shell to form a substantially continuous layer of foam of substantially uniform depth forward of the back shell. Each foam block is individually and separately removable to provide a recessed area in the otherwise continuous layer of foam to provide a customized fit to the user. The pad member overlies the front surface of the foam blocks and is received in any recessed area formed by the removal of a foam block. In this manner, the system can be customized to the deformities or other abnormalities of each individual user.Type: GrantFiled: August 23, 1993Date of Patent: April 18, 1995Inventors: Eric C. Jay, John A. Dyer, John C. Dinsmoor, III

Patent number: 5397517Abstract: A lightweight contoured base for a seat cushion is produced by first forming a shaped lightweight foam core with a void corresponding to the ischial tuberosities of a user and then forming a sandwich assembly by placing a layer of foam or foamable material against both upper and lower surfaces of the shaped lightweight foam core to form a sandwich assembly. The sandwich assembly is then molded to produce the finished contoured base for a seat cushion.Type: GrantFiled: August 13, 1993Date of Patent: March 14, 1995Assignee: Jay Medical Inc.Inventors: Eric C.

Patent number: 5395162Abstract: A seating system for wheelchairs and other applications. The seating system includes a base member with an upper surface and a fluid pad positioned on the upper surface. The upper surface is preferably contoured and dimensioned to have areas corresponding to the user's ischial tuberosities and coccyx as well as the user's femurs including trochanters. The fluid pad in the preferred embodiment is one piece and has at least three separate and distinct pouches filled with fluid. Each pouch includes seals to contain the fluid in each pouch and to isolate and prevent fluid communication with the fluid in the other two pouches. Each pouch of the pad is then respectively positioned on the upper surface of the base member under the user's ischial tuberosities and coccyx. In this manner, each of the user's ischial tuberosities and coccyx is thereby supported on its own separate and distinct fluid pouch.Type: GrantFiled: June 3, 1994Date of Patent: March 7, 1995Assignee: Jay Medical Ltd.Inventors: Eric C. Jay, John C. Dinsmoor, III, Grant C. Denton, Richard R. Runkles

Patent number: 5369829Abstract: A seating system for a wheelchair including a base member and fluid pad. The base member has forward and rearward sections respectively supporting the user's thighs and buttocks. The rearward section supporting the user's buttocks includes a depressed, seating well with front and rear upper surfaces. The fluid pad has a front-to-rear, center seal and a transverse seal dividing the pad into four pouches. The transverse seal crosses the center seal substantially closer to the rear of the pad than to the front and substantially midway across the seating well. In use, the pad is positioned on the base member wherein the user's thighs and front of the user's buttocks are supported on the forward pouches which, in turn, are positioned over the forward section of the base member and the front portion of the seating well of the base member. The remaining, rear portion of the user's buttocks is supported on the rear pouches over the rear portion of the base member.Type: GrantFiled: April 22, 1994Date of Patent: December 6, 1994Assignee: Jay Medical, Ltd.Inventor: Eric C.
