Abstract
An inspectable joint in a medical device is disclosed that includes at least one medical-grade tube having an end, a medical-grade fitting having at least one joining surface configured to accept the end of the tube, and a joining material disposed between the tube and the joining surface. The joining material includes a first component configured to couple the tube to the fitting and a second component configured to provide observable evidence of the presence of the joining material between the tube and the joining surface.
Claims19
An inspectable joint in a medical device, the inspectable joint comprising:
- at least one medical-grade tube comprising an end;
- a medical-grade fitting comprising at least one joining surface configured to accept the end of the tube;
- and
- a joining material disposed between the tube and the joining surface, the joining material comprising:
- (i) a first component configured to bond the tube to the fitting;
- and (ii) a second component configured to provide observable evidence of the presence of the joining material that is between the tube and the joining surface;
- at least a portion of the first component contacts at least a portion of the second component when the tube end is accepted by the joining surface, and at least one of the portions of the first and second components that contacts the other of the first and second components has an initial first color;
- wherein the at least a portion of one of the first and second components changes color to a second color upon contact with the portion of the other of the first and second components, and wherein the tube is separated from the joining surface by a gap, and the joining material extends around a circumference of the joint between the tube and the joining surface.
An intravenous set comprising:
- at least one medical-grade tube comprising an end;
- a medical-grade fitting comprising at least one joining surface configured to accept the end of the tube;
- and
- a joining material disposed between the tube and the joining surface, the joining material comprising:
- (i) a first component configured to bond the tube to the fitting;
- and (ii) a second component configured to provide observable evidence of the presence of the joining material;
- wherein at least a portion of one of the first and second components has an initial first color and contacts at least a portion of the other of the first and second components;
- wherein the at least a portion of one of the first and second components changes color to a second color upon contact with the portion of the other of the first and second components when the tube end is accepted by the joining surface, and wherein the tube is separated from the joining surface by a gap, and the joining material extends around a circumference of the joint between the tube and the joining surface.
An inspectable joint comprising:
- at least one tube comprising an end;
- a fitting comprising at least one joining surface configured to accept the tube end;
- and
- a bonding agent coupled between the tube end and the joining surface, the bonding agent comprising:
- (i) an adhesion component configured to bond the tube to the fitting;
- and (ii) a detectable component configured to provide evidence of the presence of the bonding agent between the tube and the joining surface;
- at least a portion of one of the adhesion and detectable components has an initial first color and contacts at least a portion of the other of the adhesion and detectable components when the tube end is accepted by the joining surface;
- wherein the at least a portion of one of the adhesion and detectable components changes color to a second color upon contact with the portion of the other of the adhesion and detectable components such that a void between the tube end and joining surface is identifiable, and wherein the tube is separated from the joining surface by a gap, and the bonding agent extends around a circumference of the joint between the tube and the joining surface.
