Abstract
An illumination assembly for use with a cannula/hub assembly that withdraws fluids from and/or injects fluids into a body. In the preferred embodiment, the illumination assembly comprises a housing and a light-emitting element mounted in and/or on the housing, for emitting directed light to an entry point on the body; wherein the housing is coupled to the cannula/hub assembly such that the location at which the cannula will enter the body remains illuminated even after the cannula has been inserted into the entry point.
Claims15
An assembly comprising:
- a cannula/hub assembly that withdraws fluids from and/or injects fluids into a person or animal, wherein the cannula/hub assembly comprises a hub having a chamber therein for receiving the fluid and a cannula that is coupled to the hub to permit communication of fluid with the hub, the cannula having a first end securable to or within the hub and a second pointed end dimensioned to permit withdrawal of fluid from and/or injection of fluid into the body by piercing the skin of the person or animal;
- and
- an illumination assembly comprising:
- a housing;
- and
- a light-emitting element mounted in and/or on the housing, for emitting
- directed light to an entry point on the body;
- wherein the illumination assembly is rotatably mounted to the cannula/hub assembly such that the illumination assembly can rotate relative to the cannula/hub assembly without dismounting the illumination assembly from the cannula/hub assembly;
- and
- wherein the light-emitting element is positioned exteriorly to the cannula/hub assembly so that the location at which the second end of the cannula will enter the skin of the person or animal is illuminateable by the light-emitting element even after the second end has been inserted into the entry point.
A method of withdrawing fluids from and/or injecting fluids into a person or animal with a cannulu/hub assembly while illuminating the location at which the cannula/hub assembly will enter the skin of the person or animal with an illumination assembly rotatably mounted to the cannula/hub assembly, wherein the cannula/hub assembly comprises a hub having a chamber therein for receiving the fluid and a cannula coupled to the hub and having an interior to permit communication of fluid with the hub, the cannula having a first end securable to or within the hub and a second end dimensioned to permit withdrawal of fluid from and/or injection of fluid into the person or animal, and wherein the illumination assembly comprises a housing, a light-emitting element mounted in and/or on the housing;
- wherein the illumination assembly is at least one of slidable along and rotatable relative to the cannula without dismounting the illumination assembly from the cannula/hub assembly and positioned exteriorly to the cannula/hub assembly, for emitting directed light to the location at which the cannula will enter the person or animal, wherein the method comprises the steps of:
- manually adjusting by at least one of sliding and rotating the position of the light-emitting element relative to the cannula/hub assembly so that the location at which the second end of the cannula will enter the skin of the person or animal remains illuminated after the second end has been inserted into the entry point;
- inserting the second end of the cannula into the skin of the person or animal;
- and
- one of withdrawing fluids from and/or injecting fluids into the person or animal.
An assembly comprising
- a cannula/hub assembly that withdraws fluids from and/or injects fluids into a person or animal wherein the cannula/hub assembly comprises a hub having a chamber therein for receiving the fluid and a cannula that is coupled to the hub to permit communication of fluid with the hub, the cannula having a first end securable to or within the hub and a second pointed end dimensioned to permit withdrawal of fluid from and/or injection of fluid into the body by piercing the skin of the person or animal;
- and
- an illumination assembly comprising:
- a housing;
- and
- a light-emitting element mounted in and/or on the housing, for emitting
- directed light to an entry point on the body;
- wherein the illumination assembly is slidably mounted to the cannula/hub assembly such that the illumination assembly is slidable along the cannula/hub assembly without dismounting the illumination assembly from the cannula/hub assembly;
- and
- wherein the light-emitting element is positioned exteriorly to the cannula./hub assembly so that the location at which the second end of the cannula will enter the skin of the person or animal is illuminateable by the light-emitting element even after the second end has been inserted into the entry point.
