Insertion of a needle into vasculature of a patient tends to invoke apprehension in the patient, as well as the clinician, for various reasons. Blood draws are a common source of needle insertions. Attempts have been made to utilize peripheral intravenous catheters (PIVCs) for withdrawing blood from the vasculature of the patient, which may reduce may a number of needle insertions experienced by a given patient.
A common type of IV catheter is an over-the-needle PIVC. As its name implies, the over-the-needle PIVC may be mounted over an introducer needle having a sharp distal tip. The sharp distal tip may be used to pierce skin and the vasculature of the patient. Insertion of the PIVC into the vasculature may follow the piercing of the vasculature by the needle. The needle and the PIVC are generally inserted at a shallow angle through the skin into the vasculature of the patient with a bevel of the needle facing away from the skin of the patient. Once placement of the needle within the vasculature has been confirmed, the clinician may temporarily occlude flow in the vasculature and withdraw the needle, leaving the PIVC in place for future blood withdrawal and/or fluid infusion.
There may be several limitations to the current PIVC blood draw approach. Current use of a PIVC to draw blood can be slow and somewhat inefficient, particularly when the patient has difficult intra-venous access or veins that are not readily accessed by the clinician. Also, blood samples obtained via a PIVC may often need to be discarded due to concerns regarding sample quality. Furthermore, current use of a PIVC to draw blood may result in kinking of blood draw tubing. Moreover, the PIVC may narrow, collapse, or clog with time, leading to failure of the PIVC.
The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one example technology area where some implementations described herein may be practiced.
The present disclosure relates generally to a delivery device and related systems and methods for delivering an instrument through an intravenous catheter. In some embodiments, the instrument may include a guidewire, a probe, blood draw tubing, a light tube, or another suitable instrument. In some embodiments, the delivery device may include a housing, which may include an outlet.

In some embodiments, the delivery device 22 may include a housing 26. In some embodiments, the delivery device 22 may include a rotary element 28, which may be disposed within the housing 26. In some embodiments, the housing 26 may include a generally cylindrical inner surface, which may allow a generally cylindrical outer surface of the rotary element 28 to rotate with respect to the housing 26. In some embodiments, the housing 26 may include an inner surface that is another shape other than generally cylindrical, and an outer surface of the rotary element 28 may include a shape corresponding to the other shape that allows the rotary element 28 to rotate with respect to the housing 26.
In some embodiments, in response to rotation of the rotary element 28 with respect to the housing 26, the instrument may be distally advanced. In some embodiments, the rotary element 28 may revolve around a central axis of rotation 29. In some embodiments, the housing 26 may include an upper and/or lower rim or ledge which may prevent the rotary element 28 from exiting an upper opening 31 and/or lower opening 33 (illustrated in
In some embodiments, the delivery device 22 may be directly coupled to a proximal end of the catheter adapter 34. In these and other embodiments, the catheter assembly 32 may include a straight or non-integrated catheter assembly. In some embodiments, the delivery device 22 may be coupled to an extension set 36 of the catheter assembly 32, as illustrated in
In some embodiments, in response to rotation of the rotary element 28 with respect to the housing 26 in a first direction, a distal end of the instrument may be advanced beyond a distal end 38 of the catheter tubing 24. Referring now to
In some embodiments, in response to rotation of the rotary element 28 with respect to the housing 26 in the first direction, the distal end 40 of the instrument 42 may be disposed a first amount beyond the distal end 34 of the catheter tubing 24. In some embodiments, in response to rotation of the rotary element 28 with respect to the housing 26 further in the first direction, the distal end 40 of the instrument 42 may be disposed a second amount beyond the distal end 34 of the catheter tubing 24. In some embodiments, the second amount may be greater than the first amount.
In some embodiments, the rotary element 28 may also rotate with respect to the housing 26 in a second direction opposite to the first direction. In some embodiments, in response to rotation of the rotary element 28 with respect to the housing 26 in the second direction, the distal end 40 of the instrument 42 may be moved proximally.

In some embodiments, the delivery device 22 may include a torque limiter, which may limit a torque of a user interface 49. In some embodiments, the torque limiter may limit the torque by slipping (as in, e.g., a friction plate slip-clutch, magnetic particle, or magnetic hysteresis torque limiter) or by uncoupling the load entirely (as in, e.g., a shear pin, synchronous magnetic, ball detent, or pawl and spring torque limiter). In further detail, in some embodiments, the user interface 49 may be coupled to and rotate with the rotary element 28 in response to the torque below a pre-determined, threshold value. In some embodiments, the user may grip and turn the user interface 49 to advance and/or retract the instrument 42. In some embodiments, in response to the torque of the user interface 49 exceeding the threshold value, the user interface 49 may release from the rotary element 28 or slip with respect to the rotary element 28, which may prevent the instrument 42 from causing vascular damage, kinking, and/or buckling. In some embodiments, when the user interface 49 releases from the rotary element 28 or slips with respect to the rotary element 28, the user may not be able to rotate the rotary element 28 via the user interface 49. In some embodiments, the rotary element 28 may not include the torque limiter and/or the user interface 49. In these and other embodiments, the protrusion 45 may act as a grip.
In some embodiments, rotation of the rotary element 28 with respect to the housing 26 may be accomplished via direct user input in which the user may physically interact with or touch the rotary element 28. For example, a hand of the user may take hold of the protrusion 45 and/or the user interface 49 to rotate the rotary element 28. In other embodiments, the rotation of the rotary element 28 with respect to the housing 26 may be driven through a mechanical coupling. In these and other embodiments, the user may not physically interact with or touch the rotary element 28 and/or the rotation of the rotary element 28 may occur in response to a linear or non-rotating action from the user, which may be introduced via a geared coupling to the rotary element 28. In some embodiments, the device may translate the linear or non-rotating action of the user into rotation of the rotary element 28.

In some embodiments, the port 48 may include an elastomeric seal or septum 47. In some embodiments, the septum 47 may be disposed in the housing 26 between the rotary element 28 and the port 48. In some embodiments, the septum 47 may maintain a seal when the instrument 42 is moved through the septum 47 and/or disposed within the septum 47, which may prevent fluid from leaking into the housing 26 and/or rotary element 28. In some embodiments, in addition to or as an alternative to the septum 47, an adhesive and/or potting agent may be disposed in the housing 26 between the rotary element 28 and the port 48. In some embodiments, the septum 47 may be assembled onto the instrument 42 and then sandwiched during assembly between the rotary element 28 and the port 48 to create a seal around the instrument 42. In some embodiments, the septum 47 may include a slit. In some embodiments, during assembly, the septum 47 may be secured within the housing 26 during assembly and/or the instrument 42 may then be inserted through the septum 47, which may be compliant.
In some embodiments, an extension tube (not illustrated) may be coupled to the port 48 and/or may extend between the port 48 and the extension set 36. In some embodiments, the extension tube may be flexible to introduce additional degrees of freedom within the catheter system 30. In some embodiments, a proximal end of the extension tube may be integrated with the port 48 or coupled to the port 48 via a connector. In some embodiments, a distal end of the extension tube may include another connector. In some embodiments, the distal end of the extension tube may be integrated with the extension set 36 or another element or coupled to the extension set 36 via the another connector.
In some embodiments, a length of the groove 44 may extend inwardly from the circumference of the rotary element 28 to and/or towards the central axis of rotation 29 of the rotary element 28. In some embodiments, at a location at which the groove 44 extends inwardly from the circumference of the rotary element 28, the groove 44 may include a gradual curve, which may avoid kinking of the instrument 42.
In some embodiments, the length of the groove 44 may extend inwardly from the circumference of the rotary element to the central axis of rotation 29, which may facilitate support of the instrument 42 as the instrument 42 exits the rotary element 28. In some embodiments, the instrument 42 may exit the rotary element 28 at another location other than the central axis of rotation 29, and the groove 44 may extend to the other location. In some embodiments, the instrument may not exit the rotary element 28 and/or a proximal end of the instrument may be secured to the rotary element 28, as will be discussed in further detail with respect to
