Patent number: 8202262Abstract: A wound closure apparatus to promote tissue healing at a wound is provided and includes a porous pad positioned at the wound and a suction pump in fluid communication with the porous pad to provide a negative pressure to the porous pad. The suction pump is disposed within a housing. A canister is fluidly connected between the porous pad and the suction pump to collect fluids drawn from the wound by the suction pump, and the canister is removably received by a recess in the housing. A wound cover is positioned over the porous pad to secure the porous pad at the wound, and a switch provides a signal indicating that the canister properly resides within the recess when the switch is pressed.Type: GrantFiled: November 2, 2009Date of Patent: June 19, 2012Assignee: KCI Licensing, Inc.Inventors: Cesar Z.

Patent number: 7784132Abstract: A system and method for maintaining an air inflation mattress configuration sufficient for patient support and comfort. Infrared illumination levels are measured within individual or groups of inflated mattress chambers. A staggered approach to illumination monitoring of chambers or sections to eliminate crosstalk between the infrared sensors is carried out. Distributed microprocessor controllers established in a network configuration utilizing controller network protocols reduces the wiring and connections necessary for the assembled system. Various mattress cushion construction techniques, such as sewing and or RF welding methods, are used for the creation of individual chambers utilizing specific types of IR translucent, transparent or reflective materials. The construction of the cushions and bladders in the system includes the use of various types of fabrics with low to high air loss qualities as required.Type: GrantFiled: April 4, 2008Date of Patent: August 31, 2010Assignee: KCI Licensing, Inc.Inventors: Juan L. Gonzalez, Kevin W. Bendele, Michael R. Oliva, Paul D. Slimpin, Cesar Z. Lina

Patent number: 7758554Abstract: A wound closure apparatus having a porous pad adapted to be fluidly connected to a vacuum pump. The pad is placed over or within a tissue site, and the vacuum pump may be activated to draw air and exudates from the tissue site. The pad contains multiple pore sizes to prevent granulation tissue from migrating into the pad as reduced pressure treatment is applied. The pad has an outer surface adjacent the wound with pore sizes of a diameter of approximately 100 microns or less to prevent tissue from growing into the pad and is treated for biocompatibility.Type: GrantFiled: May 11, 2007Date of Patent: July 20, 2010Assignee: KCI Licensing, Inc.Inventors: Cesar Z.

Patent number: 7722582Abstract: A wound closure apparatus having a housing that contains a vacuum pump and a chamber for holding a disposable wound fluid collection canister. The canister resides within the chamber and connects at an outlet with the vacuum pump at an inlet with a porous wound pad. The pad is placed over or within a wound and adhesively secured thereto. When the vacuum pump activates, it evacuates air from the canister resulting in wound fluids flowing from the wound into the canister. Due to the negative effect that a vacuum can impose on tissue when granulation tissue is pulled into the pad, the pad contains multiple pore sizes to prevent granulation tissue from migrating into the pad. The pad has an outer surface adjacent the wound with pore sizes of a diameter of approximately 100 microns or less to prevent tissue from growing into the pad and is treated for biocompatibility.Type: GrantFiled: June 20, 2003Date of Patent: May 25, 2010Assignee: KCI Licensing, Inc.Inventors: Cesar Z.

The canister resides within the chamber and connects at an outlet with the vacuum pump and at an inlet with a pad. The pad is placed over a wound and adhesively secured thereto. When the vacuum pump activates, it evacuates air from the canister resulting in wound fluids flowing from the wound into the canister. After the canister is filled, it is removed from the chamber and replaced with another canister to continue the removal of wound fluids.Type: GrantFiled: October 16, 1997Date of Patent: November 3, 2009Assignee: KCI Licensing, Inc.Inventors: Cesar Z.
