Abstract
In one embodiment, an integrated cannula and sensor assembly is disclosed. The integrated cannula and sensor assembly includes a cannula with a proximal end and a distal end. The cannula also has a body and a tip. The body includes a channel and a body distal that is defined between the proximal end and the distal end. The tip is defined between the body distal and the distal end. The assembly further includes a sensor assembly that is located within the channel, wherein the tip further includes an undercut configured to retain the sensor assembly.
Claims18
An integrated cannula and sensor assembly, comprising:
- a cannula having a proximal end, a distal end, and a fluid path within the cannula, the cannula further having a body, the body including both a body distal being defined between the proximal end and the distal end and a channel located on an exterior of the cannula, the channel having a base defined as a face opposite the fluid path, the channel further having a first cannula locating feature that extends away from the base and protrudes into the channel;
- a tip being coupled to the body distal of the cannula;
- and
- a sensor assembly being located within the channel on the exterior of the cannula, the sensor assembly having a sensor proximal end and a sensor distal end,
- wherein the coupling of the tip to the body distal defines a distal end undercut configured to retain only the sensor distal end of the sensor assembly, the distal end undercut not intersecting the fluid path.
An integrated cannula and sensor assembly, comprising:
- a cannula having a proximal end, a distal end, and a fluid path within the cannula, the cannula further having a body and a tip, the body including a first channel being located on an exterior of the cannula, a second channel also being located on the exterior of the cannula, and a body distal being between the proximal end and the distal end, the tip being between the body distal and the distal end, the first channel having a first cannula locating feature that extends away from a first channel base of the first channel, the second channel having a second cannula locating feature that extends away from a second channel base of the second channel;
- and
- a first sensor assembly being located within the first channel, the first sensor assembly having first distal end;
- a second sensor assembly being located within the second channel, the second sensor assembly having a second distal end;
- wherein the tip further includes a first distal end undercut that retains only the first distal end of the first sensor assembly and a second distal end undercut that retains only the second distal end of the second sensor assembly, both the first and second sensor assemblies not intersecting the fluid path.
