Referring to FIGS. 1 and 7, the torque limit tool 104 may include at least one engagement portion 128 to engage a leveraging tool (not shown). For example, the engagement portion 128 may include a groove into which the leveraging tool may be inserted to rotate the torque limit tool 104.
FIG. 11 illustrates a diagrammatic sectional view of the device removal tool 102 and the torque limit tool 104 of FIG. 1 in an installed configuration, illustrating operation of torque limit tool pins to rotate the first device 202, and clips to attach the torque limit tool 104 to the device removal tool 102, in accordance with an example of the present disclosure.
Referring to FIGS. 1 and 11, once the device removal tool 102 is coupled to the torque limit tool 104, the assembled multi-device removal and installation tool 100 may be positioned over the first device 202, which may include the skimmer cone, and rotated until torque limit tool pin 122 (e.g., two torque limit tool pins shown), protrudes through hole 124 to engage a complementary hole 1100 of the first device 202. In this regard, at least one clip 1102 (e.g., two clips shown in FIG. 11) of the device removal tool 102 may resiliently engage with a channel 1104 of the retainer 110 to couple the device removal tool 102 to the torque limit tool 104.
FIGS. 12A and 12B illustrate diagrammatic sectional views of the device removal tool 102 and the torque limit tool 104 in an installed configuration, illustrating operation of a separation beam 1200 of the device removal tool 102, in accordance with an example of the present disclosure.
Referring to FIGS. 1, 2, 8, 9, 12A, and 12B, the device removal tool 102 may include at least one separation beam 1200 to push, upon application of the loosening torque (e.g., clockwise direction in the orientations of FIGS. 8 and 9) to the first device 202, the device removal tool 102 toward the first device 202 to permit engagement of the plurality of catch members 306 with the engagement face 500 of the first device 202. In this regard, when the first device 202 is installed on the instrument 200, the engagement face 500 of the first device 202 may be in contact with a plane face of the manifold assembly 210. This contact may limit the position of the device removal tool 102 such that the catch members 306 become coplanar with the plane face of the manifold assembly 210 to prevent engagement of the plurality of catch members 306 with the engagement face 500 of the first device 202. Once the torque limit tool 104 is pressed in towards the first device 202, the at least one separation beam 1200 may deflect upwards in the orientation of FIG. 12A. Referring next to FIG. 12B, as the first device 202 is unscrewed, the first device 202 may push the torque limit tool 104 away from the manifold assembly 210, while the at least one separation beam 1200 may push the device removal tool 102 toward the manifold assembly 210. As the first device 202 continues to be unscrewed, a front face 1202 of the first device may rest upon a target face 1204 of the device removal tool, and the plurality of catch members 306 may engage the engagement face 500 to retain the first device 202.
Referring to FIGS. 1, 3, 4, and 6, the device removal tool 102 may further include at least one device ejector 114 that includes a tab 116 that is movable to eject the second device 204 from the device removal tool 102. In one example, the tab 116 may be depressed to eject the second device 204 from the device removal tool 102. For example, when the tab 116 is depressed, ejection face 410 may contact inner plane 604 of the second device 204 to eject the second device 204 from the device removal tool 102. Alternatively, if the ejection face 410 is contiguously engaged with the inner plane 604 of the second device 204, when the tab 116 is depressed, the ejection face 410 may be used to push the second device 204 sufficiently to overcome the removal force of the catch members 406 with the engagement face 600, and to thus eject the second device 204 from the device removal tool 102.
Referring to FIGS. 1 and 3-6, according to examples disclosed herein, the first receiver 302 and the second receiver 402 may be dimensioned to retain the first device 202 and the second device 204 at a specified height 502. For example, the specified height 502 may permit the first device 202 and the second device 204 to be immersed in a liquid or another cleaning material disposed in a container and including a specified quantity for maintenance and/or cleaning purposes, without the need to utilize different containers for the first device 202 and the second device 204.
Referring again to FIG. 1, according to examples disclosed herein, the device removal tool 102 may be formed at least of Polyetherimide (PEI). However, those skilled in the art would appreciate in view of this disclosure that the device removal tool 102 may be formed of other suitable materials that may be utilized to attach the device removal tool 102 to a device (e.g., 202 or 204), as well as to retain the device (e.g., 202 or 204) in the device removal tool 102 during performance of cleaning and other maintenance operations on the device (e.g., 202 or 204), without departing from the scope of the disclosure.
Operation of the multi-device removal and installation tool 100 is described in further detail with reference to FIGS. 1-12B.
Specifically, referring to FIGS. 1, 2, 4, and 6, with respect to utilization of the device removal tool 102 for the second device 204 that may include the sampler cone, once the second device 204 is exposed on the instrument 200, the second receiver 402 of the device removal tool 102 may be placed over and pressed onto the second device 204 until the device removal tool 102 contiguously engages inner plane 604 of the second device 204. Once the device removal tool 102 contiguously engages the inner plane 604, the catch members 406 may engage the engagement face 600 of the second device 204. The device removal tool 102 may then be withdrawn (e.g., by pulling away) from the instrument 200 with the second device 204 securely retained therein.
Once the second device 204, which is still disposed in the device removal tool 102, is removed from the instrument 200, the second device 204 may be accessed as needed for maintenance, and other purposes. For example, for the second device 204 that includes the sampler cone, features such as a cone tip, a cone orifice, cone threads, etc., may be inspected, and mechanical cleaning of the second device 204 may be performed as needed. For example, for the second device 204 that includes the sampler cone, the second device 204 may be placed into an ultrasonic cleaner with cone tip 606 facing downwards (e.g., in the orientation of FIG. 6). Various types of cleaning solutions or solvents may be utilized for cleaning of the cone tip 606. In this regard, as disclosed herein, other devices (e.g., the first device 202) may also be placed into the ultrasonic cleaner with cone tip 504 facing downwards (e.g., in the orientation of FIG. 5). Yet further, as disclosed herein, the first device 202 and the second device 204 may be retained at the specified height 502 based on the dimensions of the first receiver 302 and the second receiver 402. For example, the specified height 502 may be specified such that a specified amount of the cone tips (e.g., 504 and 606) for the first device 202 and the second device 204 are immersed in the cleaning solutions or solvents.
After completion of the maintenance and/or cleaning activities on the second device 204, the second device 204, which is still disposed in the device removal tool 102, may be stored for later use or otherwise returned to the instrument 200. If the second device 204 is to be returned to the instrument 200, the device removal tool 102, with the second device 204 retained therein, may be brought towards the instrument 200. The second device 204 may be placed back into the manifold assembly 210. The tab 116 of each device ejector 114 may be pinched to eject the second device 204 from the device removal tool 102, and the device removal tool 102 may be withdrawn (e.g., pulled away) from the instrument 200 with the second device 204 remaining in the manifold assembly 210.
With continued reference to FIGS. 1, 2, and 10, with respect to utilization of the device removal tool 102 for the first device 202 that may include the skimmer cone, the torque limit tool 104 may be coupled to the device removal tool 102 in the orientation of FIG. 1. In this regard, as disclosed herein with reference to FIG. 10, the torque limit tool 104 may include the at least one detent 1004 positioned on the inside surface 1000 into which the corresponding ball 1006 is pressed by the drive member 112. For example, the torque limit tool 104 may include six detents into which corresponding balls are pressed by the drive member 112. As disclosed herein, the engagement of the detents and balls may provide alignment of the at least one protrusion 106 to the at least one pocket 120 for coupling of the device removal tool 102 and the torque limit tool 104.
Referring to FIGS. 1, 2, 8, and 11, once the device removal tool 102 is coupled to the torque limit tool 104, the assembled multi-device removal and installation tool 100 may be positioned over the first device 202, which may include the skimmer cone, and rotated until torque limit tool pin 122 (e.g., two torque limit tool pins shown) protrudes through hole 124 to engage the complementary hole 1100 of the first device 202. The first device 202 may now be unscrewed from the manifold assembly 210 by turning knob 126 of the torque limit tool 104 in a counter-clockwise direction (e.g., clockwise in the orientation of FIG. 8).
Referring to FIGS. 1, 12A, and 12B, as the first device 202 is unscrewed, the at least one separation beam 1200 may push, upon application of the loosening torque (e.g., clockwise direction in the orientations of FIGS. 8 and 9) to the first device 202, the device removal tool 102 toward the first device 202 to permit engagement of the plurality of catch members 306 with the engagement face 500 of the first device 202.
With continued reference to FIGS. 1, 12A, and 12B, the torque limit tool 104 may be decoupled (e.g., by pulling apart) from the device removal tool 102, and the first device 202 may be removed from the instrument 200, securely retained in the device removal tool 102.
In a similar manner as discussed above for the second device 204, with reference to FIGS. 1-3 and 5, once the first device 202, which is still disposed in the device removal tool 102, is removed from the instrument 200, the first device 202 may be accessed as needed for maintenance, and other purposes. For example, for the first device 202 that includes the skimmer cone, features such as a cone tip, a cone orifice, cone threads, etc., may be inspected, and mechanical cleaning of the first device 202 may be performed as needed. For example, for the first device 202 that includes the skimmer cone, the first device 202 may be placed into an ultrasonic cleaner with the cone tip 504 facing downwards (e.g., in the orientation of FIG. 5). Various types of cleaning solutions or solvents may be utilized for cleaning of the cone tip 504. In this regard, as disclosed herein, other devices (e.g., the second device 204) may also be placed into the ultrasonic cleaner with the cone tip 606 facing downwards (e.g., in the orientation of FIG. 6). Yet further, as disclosed herein, the first device 202 and the second device 204 may be retained at the specified height 502 based on the dimensions of the first receiver 302 and the second receiver 402. For example, the specified height 502 may be specified such that a specified amount of the cone tips (e.g., 504 and 606) for the first device 202 and the second device 204 are immersed in the cleaning solutions or solvents.
Referring to FIGS. 1, 2, and 8, after completion of the maintenance and/or cleaning activities on the first device 202, the first device 202, which is still disposed in the device removal tool 102, may be stored for later use or otherwise returned to the instrument 200. If the first device 202 is to be returned to the instrument 200, the device removal tool 102, with the first device 202 retained therein, may be brought towards the instrument 200. The first device 202 may be partially threaded onto the manifold assembly 210. The torque limit tool 104 may be coupled with the device removal tool 102 by engaging the torque limit tool pin 122 (e.g., two torque limit tool pins shown) through hole 124 to engage the complementary hole 1100 of the first device 202. The first device 202 may now be screwed into the manifold assembly 210 by turning knob 126 of the torque limit tool 104 in a clockwise direction (e.g., counter-clockwise in the orientation of FIG. 8). As the torque that is applied to tighten the first device 202 increases, the at least one torque beam 108 of the device removal tool 102 may deflect (e.g., outwards in the orientation of FIG. 8), upon application of the tightening torque that exceeds a torque threshold, the at least one torque beam 108 to limit the tightening torque that is applied to the first device 202. Generally, the torque beam 108 may deflect when torque that is applied to tighten the first device 202 reaches approximately 4 Nm or more, such as from approximately 4 Nm to approximately 5 Nm. In this manner, the torque beam may prevent overtightening of the first device 202 when the first device 202 is rotatably attached back onto the instrument 200. Once the at least one torque beam 108 deflects outwards, the knob 126 may spin freely, and the assembly including the device removal tool 102 and the torque limit tool 104 may be pulled away from the installed first device 202.
