Abstract

An adapter slip configured to be seated in a fluid port, the adapter slip including a lumen, an exterior wall, a shoulder, and a sleeve. The lumen extending along a length of a longitudinal axis, the lumen configured to receive a temperature probe. The exterior wall including a proximal end portion and a distal end portion, wherein the proximal end portion includes a tapered portion tapered at an acute angle with respect to the longitudinal axis. The shoulder extending outward from the exterior wall distal to the tapered portion configured to engage with a distal end of the fluid port. The sleeve configured extend within the lumen and project a predetermined distance beyond the proximal end portion of the exterior wall, the sleeve including a sleeve lumen and a closed proximal end, the sleeve lumen configured to receive at least a temperature sensor of the temperature probe.

Claims

1. A probe assembly configured to removably attach to multiple different fluid ports of a heart-lung machine to measure temperature of blood flow, the probe assembly, comprising:

a temperature probe including an extender, a temperature sensor positioned at a proximal end of the extender, and a wire coupled to the temperature sensor configured to transmit data from the sensor related to the temperature of blood flow in the heart-lung machine; and

an adapter slip configured to receive the temperature probe and configured to be seated in each of the multiple different fluid ports of the heart-lung machine, the adapter slip including a proximal end, an external shoulder, a longitudinal axis, and a lumen;

wherein the external shoulder is configured to provide an engagement stop with a distal end of each of the multiple different fluid ports; and

wherein the proximal end of the adapter slip has a tapered portion tapered at an acute angle with respect to the longitudinal axis such that at least a portion of the tapered portion provides an interference fit with an interior surface of each of the multiple different fluid ports.

2. The probe assembly of claim 1, further comprising a sleeve seated within the lumen of the adapter slip, the sleeve comprising:

a sleeve lumen having an interior diameter configured to allow insertion of the temperature probe;

a closed proximal end positionable at a predetermined distance proximal to the proximal end of the adapter slip.

3. The probe assembly of claim 1, wherein the adapter slip further comprises a locking port configured to engage with a locking mechanism of the temperature probe.

4. The probe assembly of claim 1, further comprising a collar coupled to the adapter slip distal to the external shoulder and apart from a fluid port of the multiple different fluid ports, the collar configured to selectively engage with an exterior surface of the fluid port.

5. The probe assembly of claim 4, wherein the collar includes helical grooves configured to provide a screw-fit receptor for the fluid port.

6. The probe assembly of claim 4, wherein the adapter slip further comprises a ring stop configured for engagement with the collar.

7. The probe assembly of claim 1, further comprising adhesive applied between an exterior wall at the proximal end of the adapter slip and the interior surface of the fluid port.

8. The probe assembly of claim 1, wherein the adapter slip further comprises an external circumferential rib configured to provide at least partial interference and seal with the interior surface of the fluid port.
