Patent number: 5588954Abstract: A fluid connector for a compression system for improving venous blood flow in a patient provides a continuous fluid passageway between a source of pressurized fluid and a plurality of inflatable chambers in an elongated pressure sleeve. The connector includes a flexible conduit comprising a plurality of elongate hollow tubes having a corresponding plurality of fittings attached at one end of the conduit. The fittings form a fluid-tight seal between the conduit and a corresponding plurality of outlet ports communicating with the source of pressurized fluid. A grip portion is provided adjacent the end of the conduit. The grip portion is releasably attached to the source of pressurized fluid and grips the conduit securely between adjacent tubes such that the fittings move freely and independently relative to the grip portion. In this manner, leakage of the pressurized fluid and contamination of the fluid stream is minimized, while stresses induced in the conduit are not transferred to the fittings.Type: GrantFiled: April 5, 1994Date of Patent: December 31, 1996Assignee: Beiersdorf-Jobst, Inc.Inventors: Philip P. Ribando, Kenneth M. Bolam, Donald H. Peeler, Terry L. Sandman

Patent number: 5582580Abstract: A heart massager for substernal heart massage is disclosed. The heart massager has a heart-contacting member having a surface which is at least partially concave for contacting the heart, cushioning on the surface of the contact member, and a handle attached to the heart-contacting member for manually manipulating the massager. The partially concave surface allows the heart-contacting member to conform to the shape of the heart. The handle is substantially upright with respect to the surface of the heart-contacting member. The handle is significantly offset from a central portion of the heart-contacting member in the region where it attaches to the member. The cushioning covers substantially the entire surface of the heart-contacting member so as to form a solid surface.Type: GrantFiled: May 27, 1994Date of Patent: December 10, 1996Assignee: Temple University - Of The Commonwealth System of Higher EducationInventors: Robert F. Buckman, Jr., Michael M. Badellino

Patent number: 5571074Abstract: A heart massager for substernal heart massage is disclosed. The heart massager utilizes a heart-contacting member adapted for insertion into a thoracic cavity for directly contacting the heart and a handle attached thereto for manually manipulating the apparatus. The heart-contacting member includes a cup having one end which is open and which receives the handle, and another end which is closed by an at least partially concave-shaped diaphragm which forms a heart contacting surface and allows the member to conform to the shape of the heart's surface. The ends of the cup are joined by a flexible sidewall which flares outward from the handle in its operative state. The cup's flexible sidewall allows the heart-contacting member to collapse so that it can be inserted into a relatively small incision in the chest cavity. After the heart-contacting member is inserted, fluid pressure is applied to the inside of the cup, thereby causing it to expand into its operative state.Type: GrantFiled: May 27, 1994Date of Patent: November 5, 1996Assignee: Temple University-Of The Commonwealth System of Higher EducationInventors: Robert F. Buckman, Jr., Michael M. Badellino
