[0004] The present invention relates to an improved method and system for accessing the vasculature of a patient. The present invention also relates to a technique for delivering fluids and medications to a patient. 1. Technical Field

[0005] The present invention relates to the field of placing a central line in a patient's vasculature using a catheter over needle technique. The present invention also relates to minimally invasive IV placement. The present invention even relates to reducing the time and discomfort a patient experiences when receiving a central line. 2. Background technology

[0006] Traditional placement of a central line using the Seldinger technique is time consuming and unpleasant to the patient. Although the Seldinger technique is widely used, it involves a large number of steps and parts. This has two major disadvantages. First, the longer sequencing time and the multiple parts involved increase the possibility of patient trauma. Second, the numerous steps involving multiple parts entering and leaving the patient's bloodstream during the procedure increases the risk of introducing contaminants into the patient, who is often immunocompromised and at risk for further infection. Another disadvantage of the Seldinger technique is the high degree of sterility required due to the numerous steps and multiple parts. See Figures 4a to 4c for a depiction of the needle being located on the catheter central line. Therefore, there is a need to reduce the number of steps and parts required to place a central line.

[0018] The present invention solves multiple problems with placing a central line into a patient. The present invention provides a solution that is as easy and quick to deploy as a peripheral IV. The present invention can reduce the need for over-sterilization of the components of the system. The present invention also provides a more comfortable procedure for the patient. The present invention provides a shorter central line, thereby achieving a more relaxed experience for the provider placement of the central line. The present invention also provides an even shorter catheter line that utilizes a trocar technology that is superior to the trocar technology in the prior art.

[0019] According to the description provided, a method and system for introducing intravenous fluids and medications to a patient is disclosed.

[0020] In one embodiment of the system of the present invention as seen in Figure 1a, the system uses a trocar technique to place the central line into the patient's bloodstream. Although the traditional central line is about 20 cm long, the system of the present invention may include a shorter length, thereby enabling the use of a trocar technique through the central lumen. In one embodiment of the system of the present invention, the lumen may be about 8 cm, or in the range between 8 cm and 12 cm. In other embodiments, the lumen may be in the range of 2 cm to 18 cm. In yet another embodiment, the first lumen, the second lumen, and the third lumen may have different lengths in the range of 2 cm to 18 cm.

[0021] The system of the present invention may include a triple lumen 5, which includes at least two volume values. In one embodiment of the present invention, the 3 separated lumens may include a central lumen 10 with a volume value of 18g, and the second lumen 20 and the third lumen 30 may each have a volume value of 22g. In other embodiments of the present invention, the range of volume values ​​may be 12g-24g for the central line, and may be 12g-24g for the second lumen and the third lumen. Further observing Fig. 1b, the central lumen 10 is shown as being located inside the second lumen 20 and the third lumen 30. Other configurations and arrangements of the central lumen, the second lumen and the third lumen are fully within the scope of the present invention, including those configurations and arrangements in which the central lumen is partially located inside or outside the second lumen and the third lumen. The triple lumen may include a catheter joint hub 40, in which the second lumen 20 and the third lumen 30 are separated from the port 60 of the catheter joint hub 40. After the second and third lumens 20, 30 emerge from the catheter connector 40, the clamp 25 may be applied to ensure that static pressure is maintained. In other embodiments, the second and third lumens 20, 30 may have other configurations on the exterior of the catheter connector other than those shown in FIG. 1 , which are well within the scope of the present invention.

[0022] In another embodiment of the present invention, multi-lumen can comprise central lumen 10 and at least one non-central lumen.Multi-lumen catheter can extend between patient's blood flow and catheter joint hub 40, thereby catheter flow is separated, to carry medicine and fluid simultaneously and to extract blood by any one in central lumen 10 or at least one non-central lumen.In another embodiment of multi-lumen, central lumen 10 will be able to terminate farther than at least one non-central lumen, thereby making system can self-expand during insertion.In another embodiment of multi-lumen, the distal end of any one in lumen can be tapered, thereby making system can self-expand during insertion.As depicted, central lumen 10 is shown in Fig. 1b as having pipeline caliber slightly larger than pipeline caliber of non-central lumen.Central lumen 10 can have distal end 45 at the top of Fig. 1a and have catheter joint end 60 at the bottom of Fig. 1a. At the distal end, the catheter can include terminal points 27 and 37 for the non-central lumens 20 and 30, and the terminal points 27 and 37 are positioned along the portion of the multi-lumen that is configured to be placed within the patient's blood flow. Therefore, the terminal points 27 and 37 can connect the contents of the non-central lumen to the patient's blood flow and further draw blood from the patient's body into one of the non-central lumens 20, 30. In various embodiments of the present invention, the distal end 45 of the catheter can be tapered. Figure 1 shows an embodiment of a tapered multi-lumen between the terminal points 27, 37 and the distal end 45. In other embodiments, the tapered multi-lumen can be produced by the terminal points 27, 37 in an incremental or smooth transition manner. Although an example of a tapered end is shown in Figure 1a, it should not be understood as a limitation on the scope of how to construct the triple lumen, as it may have other geometric configurations.

[0023] In another embodiment of the present invention, the multi-lumen can extend proximally through the catheter connector hub, thereby separating into independent lines inside or outside the catheter connector hub. In another embodiment not depicted, the central lumen can be separated from the non-central lumen line, and the non-central lumen line remains incorporated into the source input of the drug or other beneficial additives.

[0024] exist Figure 6 In another embodiment of the present invention as seen in Fig. 1, lumen Luer connector 90 can be directly or indirectly communicated with catheter connector hub 40. Lumen Luer connector 90 can touch central lumen 10 by passing through port 60 of catheter connector hub 40, as shown in the figure. In other embodiments, lumen Luer connector 90 can touch central lumen 10 by other connectors known in the art. In another alternative embodiment, non-Luer connector docks with catheter connector hub and is connected with any needleless connector to deliver regulated input to the patient. Such connector can enable the user to implement trocar technique by the system of the present invention in Fig. 1a.

[0025] In another embodiment of the present invention, the Figure 2 The catheter can be inserted by using a syringe and needle 70 shown in the figure to draw blood from the through hole in the patient to ensure correct placement. The needle 75 of the syringe can be inserted through the central lumen 10, and the catheter can be tapered at the distal end 45 toward the distal end 45 of the catheter. Therefore, the catheter can be fed over the needle 75 of the syringe 70.

[0026] In yet another embodiment of the present invention, the catheter can be utilized via its port 60 via the flashback lumen 80, such as Figure 3 As shown. The needle 85 of the flashback chamber 80 can be inserted through the port 60 through which the catheter 5 is passed, and the catheter can taper as it approaches the distal end 45 of the catheter. Thus, the catheter can be fed over the needle 85 of the syringe 70. In another embodiment of the present invention, a process for implementing a trocar technique to place a central line is disclosed. Depending on the patient's needs and medical goals, the multi-lumen tube of the present invention (such as the multi-lumen tube shown in Figure 1a) can be used with a syringe ( Figure 2 ) or reflux cavity ( Figure 3 ) connection. A syringe or flashback chamber can be connected to the hub on the proximal side of the catheter connector hub. The needle of the syringe or flashback chamber can then be inserted into the patient's vasculature, allowing the catheter 5 of the system of the present invention to be placed through the vasculature and into the patient's bloodstream. The needle can be withdrawn and the system of the present invention secured for use.

[0027] A Luer lock or other Luer connector can be placed on the central Luer connector of the catheter joint hub to control access to the central lumen. The multi-lumen can include a central lumen and at least one non-central lumen extending between the distal end of the catheter and the catheter joint hub. In an alternative embodiment, the catheter 5 can be a merged or separated lumen between the patient's blood flow and the catheter joint hub. The method of the present invention can also include: separating the multi-lumen into one or more independent lumens when the multi-lumen enters the catheter joint hub, so that the independent lumens can be selectively sealed or have static pressure; extracting blood from the patient's body through the central lumen, at least one non-central lumen or any independent lumen; delivering drugs or fluids via the central lumen, at least one non-central lumen or any independent lumen.

[0028] In another embodiment of the present invention shown in Fig. 4a to Fig. 4e, the system uses the trocar technique to place the central line into the patient's bloodstream. Although the traditional central line is about 20cm long, the system of the present invention may include a shorter length, thereby enabling the use of the trocar technique through the central lumen. In one embodiment of the system of the present invention, the lumen may be about 6cm, or in the range between 5cm and 10cm. In other embodiments, the lumen may be in the range of 2cm to 18cm. In yet another embodiment, the first lumen, the second lumen, and the third lumen may have different lengths in the range of 2cm to 18cm.

[0029] Further observing Figure 4a, the system of the present invention may include a triple lumen 5, which includes at least two volume values. In one embodiment of the present invention shown in Figure 1b, the three separated lumens may include a central lumen 10 with a volume value of 16g-18g, and the second lumen 20 and the third lumen 30 may each have a volume value of 18g-20g. In other embodiments of the present invention, the range of volume values ​​may be 12g-24g for the central line, and 12g-24g for the second lumen and the third lumen. Further observing Figure 1b, the central lumen 10 is shown as being located inside the second lumen 20 and the third lumen 30. Other configurations and arrangements of the central lumen, the second lumen, and the third lumen are fully within the scope of the present invention, including those configurations and arrangements in which the central lumen is partially located inside or outside the second lumen and the third lumen. More closely observing Figures 4a to 4e, the system of the present invention used during insertion into a patient's body is shown. The triple lumen can include a catheter connector hub 40, wherein the second lumen 20 and the third lumen 30 are separated from the port 60 of the catheter connector hub 40. According to an embodiment of the present invention, the catheter connector hub 40 can be configured in various geometrically different structures. In this embodiment, the catheter connector hub can be understood as a single union for merging the triple lumen 5 with the input line and establishing a contact point with the patient. In other embodiments not shown, the catheter connector hub 40 can have different parts and functions that are not in a single union. As shown in Figures 4a to 4e, the hub 40 may include at least one member 50, and as shown, include a first member 50 and a second member 50 extending from the hub 40. The member 50 shown may include at least one component element, and as shown, include an upper component element 53 and a lower component element 55. The upper component element 53 and the lower component element 55 can be used to attach the catheter connector hub 40 to the patient's skin by various means (including medical tape, wrapping, suture staples and / or other skin attachment methods known in the medical field). Although the members 50 are shown extending in a generally perpendicular relationship to the triple lumen 5, it is also entirely within the embodiments of the present invention that one or more members 50 extend from the hub 40 in other directions. In addition, one or more members 50 may extend toward or away from the patient, rather than just extending transversely to the hub 40. In yet other embodiments, the hub 40 may be understood to extend from the x-axis, y-axis, and z-axis established and referenced by the triple lumen 5 within a range of 360 degrees. After the second lumen 20 and the third lumen 30 emerge from the catheter connector 40, the clamp 25 may be applied to ensure that static pressure is maintained. In other embodiments, the second lumen 20 and the third lumen 30 may have other configurations on the outside of the catheter connector other than those shown in FIG. 1, which are entirely within the scope of the present invention.

[0030] The system of the present invention can be utilized through its port 60 via a flashback lumen 80, as shown in the sequence shown in Figures 4b to 4e. The needle 85 of the flashback lumen 80 can be inserted through the port 60, through which the catheter 5 is passed, which can taper as it approaches the distal end 45 of the catheter. Figure 5 In another interaction within the process of the system of the present invention shown in , the catheter 5 and particularly the central lumen 5 as accessed via port 60 can be fed over the needle 85 of the syringe 70, allowing the medical professional to introduce prescription input isolated through the central lumen 10.

[0031] like Figure 6 As can be seen, the system of the present invention can interact with a Luer lock connection 90, which can be in direct or indirect communication with the catheter connector hub 40. The lumen Luer connection 90 can access the central lumen 10 through a port 60 that passes through the catheter connector hub 40, as shown. In one embodiment of the present invention, the port can simply represent an extension of the central lumen as the central lumen emerges from the hub 40, or in other embodiments of the present invention, the port can include other portions and materials extending between the central lumen entering the hub 40 and emerging through the port. In other embodiments, the lumen Luer connection 90 can access the central lumen 10 through other connections known in the art. In yet another alternative embodiment, a non-Luer connector docks with the catheter connector hub and connects to any needleless connector to deliver regulated input to the patient. Such a connection can enable a user to access the central lumen 10 through Figures 4a to 4e, Figure 5 and Figure 6 The system of the present invention implements the trocar technique.

[0032] In another embodiment of the present invention, multi-lumen can comprise central lumen 10 and at least one non-central lumen.Multi-lumen catheter can extend between patient's blood flow and catheter joint hub 40, thereby catheter flow is separated, to carry medicine and fluid simultaneously and draw blood by any one in central lumen 10 or at least one non-central lumen.In another embodiment of multi-lumen, central lumen 10 can comprise the size different from the size of at least one non-central lumen, thereby makes system self-expanding during insertion.In another embodiment of multi-lumen, the distal end of any one in lumen can be tapered, thereby makes system self-expanding during insertion.As depicted, central lumen 10 is shown in Fig. 1b as having pipeline caliber slightly larger than pipeline caliber of non-central lumen.Central lumen 10 can have distal end 45 at the top of Fig. 1 and have catheter joint end at the bottom of Fig. 1b. At the distal end, the catheter can include terminal points 27 and 37 for the non-central lumens 20 and 30, and the terminal points 27 and 37 are positioned along the portion of the multi-lumen that is configured to be placed in the patient's blood flow. Therefore, the terminal points 27 and 37 can communicate the contents of the non-central lumen with the patient's blood flow and further draw blood from the patient's body into one of the non-central lumens 20, 30. In various embodiments of the present invention, the distal end 45 of the catheter can be tapered. Figure 1 shows an embodiment of a tapered multi-lumen between the terminal points 27, 37 and the distal end 45. In other embodiments, the tapered multi-lumen can be produced by the terminal points 25, 35 in an incremental or smooth transition manner. Although examples of tapered ends are shown in Figures 4a to 4c, they should not be construed as limitations, and they can have other geometric configurations not shown herein.

[0033] Other variations and specialized environments can be implemented through this.

[0034] Although the present invention has been described in conjunction with the specific embodiments set forth above, many alternatives, modifications and other variations thereof will be apparent to those skilled in the art. All such alternatives, modifications and variations are intended to fall within the spirit and scope of the present invention.
