Patent number: 4637917Abstract: A bubble oxygenator for oxygenating blood in an extracorporeal circuit. The oxygenator is formed from three concentric shells which define an oxygenating chamber, a defoaming chamber and an arterial reservoir. The arterial reservoir includes a view chamber which permits visual inspection of the level of blood held in the arterial reservoir. The outer shell which forms the arterial reservoir is rotatable with respect to the remainder of the apparatus so that the view chamber can be easily positioned for observation.Type: GrantFiled: October 14, 1983Date of Patent: January 20, 1987Inventors: Charles C.

Patent number: 4631050Abstract: An autotransfusion system for salvaging, washing, and concentrating blood and returning the blood to a patient during surgery. The system comprises both a filtration unit and an ultrafiltration unit. The ultrafiltration unit is configured so as to communicate with the filtration unit, and both the filtration unit and the ultrafiltration unit are provided with a suitable conduit for conveying blood back to a patient. The ultrafiltration unit is divided into two chambers by a semipermeable membrane, the membrane being selected so as to permit fluid to pass therethrough, while preventing the passage of blood cells and other formed elements.A mixture of healthy blood cells, fluid, and particulate debris is salvaged from an operative field of a patient. The blood mixture is filtered in the filtration unit and can then be immediately returned to the patient, if needed.Type: GrantFiled: September 24, 1985Date of Patent: December 23, 1986Inventors: Charles C. Reed, Denton A. Cooley

Patent number: 4422939Abstract: A blood and perfusate filter apparatus having a pair of molded housing members that are substantially identical in their configuration. The upper housing member having a pyramidal-shaped reservoir formed in the upper surface thereof which acts as a secondary distribution reservoir, and the lower housing member having a pyramidal-shaped reservoir formed in the lower surface thereof which acts as a secondary collection reservoir. Interchangeable tubing couplings are press-fit bonded to inlet/outlet ports located in the secondary reservoirs. A filter element, mounted in a resinous band, is bonded between the housing members so as to filter blood or perfusate as it passes through the filter. The filter element also forms primary distribution and collection reservoirs with respect to the upper and lower housing members. Different types of filter configurations, such as flat or pleated, can be mounted in a resinous band and used as the filter media.Type: GrantFiled: April 8, 1982Date of Patent: December 27, 1983Assignee: Texas Medical Products, Inc.Inventors: Russell G.

Patent number: 4180896Abstract: A blood oxygenator having two separable components one of which is disposable and the other of which is reusable and sterilizable. The disposable portion of the oxygenator is multichambered and provides an oxygenating chamber, a defoaming chamber and an arterial reservoir constructed so that blood will flow sequentially therethrough. The reusable member is constructed in the form of a cover for the oxygenator and has depending therefrom a heat exchanger for maintaining the temperature of the blood, the heat exchanger projecting telescopically into the oxygenating chamber. Defoaming is assisted by a cellular foam material rolled into a generally cylindrical configuration and having abutting faces which are bias cut so that the line formed by the abutting faces is not coaxial with the blood flow path.Type: GrantFiled: October 16, 1978Date of Patent: January 1, 1980Assignee: Texas Medical Products, Inc.Inventors: Charles C. Reed, Denton A. Cooley, Russell G. Sharp

Patent number: 4068664Abstract: The disclosed surgical suction wand assembly and method includes a modular suction wand including a hollow suction tip the interior of which has a square or other suitable polygonal cross-sectional configuration which substantially improves the precision and facility with which apertures may be formed in the suction tip. The tip may be provided with an elongated interiorly disposed tube simultaneously providing for effective aspiration of small amounts of liquid as well as a large suction area for efficiently aspirating larger volumes with minimal opportunity for obstruction. The suction tip is provided with a coupling device adapted to receive any one of a plurality of adaptor configurations constructed so as to increase the versatility of the suction tip without requiring large numbers of separate forming molds.Type: GrantFiled: February 25, 1976Date of Patent: January 17, 1978Assignee: Texas Medical Products, Inc.Inventors: Russell G.
