[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 112,042, filed November 10, 2020, entitled “Sleeve Connector with Adhesive Groove,” the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] This invention relates to a sleeve connector with an adhesive groove. Background Technology

[0004] Cannula connectors are used in the medical field in devices for controlling fluid flow to a patient, such as for fluid flow from intravenous (IV) gravity or pump kits. When adhesive is applied to the outside of the cannula and assembled into the tubing, conventional cannula connectors do not provide sufficient tubing retention force due to the lack of an adhesive layer that bonds the fitting to the cannula surface. As the cannula is pushed into the tubing, adhesive on the outer surface of the cannula tends to be rubbed off the cannula and seep from the cannula / tubing connection due to the frictional fit between the cannula and tubing. It is desirable to provide a cannula connector that provides a bonding layer between the tubing and cannula surfaces, thereby increasing the tubing retention strength of the cannula / tubing connection. Summary of the Invention

[0005] This disclosure provides a medical cannula connector having one or more grooves disposed on the outer surface of the cannula, which increases the surface area of ​​the cannula and generates more adhesive surface area compared to a typical cannula design.

[0027] The detailed descriptions below depict various configurations of the subject matter and are not intended to represent the only configuration in which the subject matter can be practiced. For the purpose of providing a thorough understanding of the subject matter, the detailed descriptions include specific details. Therefore, dimensions are provided for certain aspects as non-limiting examples. However, it will be apparent to those skilled in the art that the subject matter can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring the concepts of the subject matter.

[0028] It should be understood that this disclosure includes examples of the subject matter and does not limit the scope of the appended claims. Various aspects of the subject matter are now disclosed based on specific, but not limiting, examples. The various embodiments described in this disclosure can be implemented in different ways and variations, and are suitable for desired applications or practices.

[0029] As shown in Figure 1, a typical infusion kit 30 has several different components, including a drip chamber 40, a check valve 50, a roller clamp 60, and a Y-joint 70, all of which are connected together via tubing 20. A typical infusion kit 30 may include additional infusion components (e.g., spring clamps, filters) and can be formed by any combination of components and tubing 20.

[0030] Many infusion kit components 40, 50, 70 have male connectors or sleeves that mate with the end section of fitting 20 to form a connection between infusion kit components 40, 50, 70 and fitting 20. For example, as shown in Figure 2, a typical Y-connector 70 has inlet ports 72, 74 and an outlet port 76, where each inlet port 72, 74 connects to inlet tubes 22, 24, and the outlet port 76 connects to outlet tube 26. Here, inlet port 74 is a sleeve, where inlet tube 24 slides onto or slides on inlet port 74 by a tight fit (e.g., friction fit). Typically, because a friction fit alone is insufficient to ensure that inlet tube 24 remains connected to inlet port 74, glue or solvent is applied to the outside of inlet port 74 and then pushed into the end of inlet tube 24. However, as the inlet tube 24 slides downwards along the smooth surface of the inlet port 74, the tight fit of the inlet tube 24 causes the adhesive to be pushed downwards, where it seeps out from the base of the inlet port 74. Because most or all of the adhesive is essentially scraped off from the smooth surface of the inlet port 74, many areas of the outer surface of the inlet port 74 may have a very thin layer of adhesive or no adhesive layer at all, thus providing little or no bonding support for the friction fit.

[0031] According to various aspects of this disclosure, the sleeve connector is provided with one or more grooves arranged on the outer surface of the sleeve. The grooves provide notches or recesses in which adhesives (e.g., glue, solvents) can reside, which prevents all adhesives applied to the sleeve from being scraped off as the tube slides up and down along the length of the sleeve.

[0032] Figure 3-6 A sleeve connector 100 according to some aspects of this disclosure is shown. The sleeve connector 100 includes a housing 110, a sleeve 130 extending from the housing 110, and a sleeve member 140 extending from the housing 110. The housing 110 has a first fluid port 112 configured to provide fluid flow into and out of the housing 110. For example, the first fluid port 112 may be a female connector receiving an end face of a tube 20 (e.g., tube 22). The sleeve 130 has a second fluid port 132 configured to provide fluid flow into and out of the sleeve 130. For example, as... Figure 3 As shown, sleeve 130 is a male protrusion inserted into tube 20 (e.g., tube 24) so ​​that fluid can flow from tube 20 into second fluid port 132, or flow out from second fluid port 132 into tube 20. Figure 3As can be seen, the engagement portion 25 of the tube 20 is the part where the tube mates with the sleeve 130, wherein the engagement portion 25 protrudes due to the frictional engagement between the inner surface 23 of the tube 20 and the sleeve 130. In some aspects of this disclosure, the sleeve 130 may be sized the same as the inner surface 23 of the tube 20 for contact engagement, wherein the engagement portion 25 does not protrude. The sleeve 130 may also include a tapered portion 131 disposed at the leading edge of the sleeve 130. The tapered portion 131 may provide an inclined surface to allow the sleeve 130 to slide more easily into the end portion 21 of the tube 20.

[0033] The sleeve 130 includes one or more grooves 134 disposed (e.g., disposed within the outer surface 136) around the outer surface 136 of the sleeve 130. The grooves 134 may be uniformly and / or randomly disposed around the outer surface 136 of the sleeve 130. The grooves 134 may be of any suitable configuration, such as axial, transverse, helical, or any combination thereof. The dimensions and shape of the grooves 134 are configured to retain an adhesive (e.g., glue, solvent) thereby providing a bonding layer 138 in the outer surface 136 between the tube 20 and the sleeve 130. The bonding layer 138 increases the retention strength of the tube 20 to the sleeve 130 relative to a single friction fit. Additional tube retention strength can be fine-tuned by adjusting parameters of the grooves 134 (e.g., the length of each groove 134, the number of grooves 134, and the geometry of the grooves 134). For example, some or all of the grooves 134 may have a length that substantially matches the length of the sleeve 130, or some or all of the grooves 134 may have a length that extends along a portion of the length of the sleeve 130 (e.g., half the length of the sleeve 130). As another example, Figure 4-6 The sleeve connector 100 has 16 grooves 134. Figure 10 The sleeve connector 300 shown has 24 grooves 334, and Figure 11 The sleeve connector 400 shown has 32 grooves 432. As yet another example, although... Figure 6 The groove 134 shown is triangular in geometry, but the groove 134 can have any desired geometry (e.g., rectangular, semi-circular, trapezoidal) or any combination of different geometries (e.g., some triangles and some trapezoids). In aspects of this disclosure, the groove 134 can extend into the tapered portion 131. In aspects of this disclosure, the groove 134 can stop before or at the beginning of the tapered portion 131, thereby providing a smooth outer surface for the tapered portion 131.

[0034] The sleeve member 140 can be configured to partially enclose the end portion 21 of the tube 20. The sleeve member 140 can be configured as a single circular sleeve that encloses the entire end portion 21 of the tube 20. The sleeve member 140 can be configured not to contact the outer surface 27 of the tube 20, such as... Figure 3 As shown, the sleeve member 140 may be configured to engage with the outer surface 27 of the tube 20. For example, adhesive may be applied to the inner surface 142 of the sleeve member 140 to provide another bonding layer between the inner surface 142 of the sleeve member 140 and the outer surface 27 of the tube 20, and / or the sleeve member 140 may be configured to provide a tight frictional fit between the inner surface 142 of the sleeve member 140 and the outer surface 27 of the tube 20. In some aspects of this disclosure, a groove may be added to the inner surface 142 of the sleeve member 140 to provide a similar engagement feature to the groove 134. In some aspects of this disclosure, the sleeve connector 100 may not have the sleeve member 140 at all.

[0035] During assembly, an adhesive (e.g., glue) is applied to the outer surface 136 of the sleeve 130, and the end portion 21 of the tube 20 is slid onto the sleeve 130 and along its length until the end portion of the tube contacts the stop surface 114 of the housing 110. The adhesive collected in the groove 134 then solidifies to form a bonding layer 138 in the outer surface 136, which bonds to a corresponding portion of the inner surface 23 of the tube 20, providing additional resistance to the movement of the tube 20 on the sleeve 130, exceeding the resistance of the frictional fit between the tube 20 and the sleeve 130.

[0036] Figure 7-9 A sleeve connector 200 according to some aspects of this disclosure is shown. The sleeve connector 200 includes a housing 210, a base member 240 extending from the housing 210, and a sleeve 230 extending from the base member 240. The housing 210 has a first fluid port 212 configured to provide fluid flow into and out of the housing 210. For example, the first fluid port 212 may be a female connector receiving an end face of a tube 20 (e.g., tube 22). The sleeve 230 has a second fluid port 232 configured to provide fluid flow into and out of the sleeve 230. For example, as... Figure 7-9 As shown, the sleeve 230 is configured to insert into the male protrusion in the tube 20 (e.g., tube 24) so ​​that fluid can flow from the tube into the second fluid port 232, or flow out of the second fluid port 232 into the tube.

[0037] The sleeve 230 includes one or more grooves 234 (e.g., channels) disposed around the outer surface 236 of the sleeve 230. The grooves 234 are sized and shaped to retain an adhesive (e.g., glue, solvent) thereby providing a bonding layer 238 in the outer surface 236 between the tube (e.g., tube 20) and the sleeve 230. The bonding layer 238 increases the retention strength of the tube to the sleeve 230 relative to a single friction fit. Additional tube retention strength can be fine-tuned by adjusting parameters of the grooves 234, such as the length of each groove 234, the number of grooves 234, and the geometry of the grooves 234. For example, some or all of the grooves 234 may have a length that substantially matches the length of the sleeve 230, or some or all of the grooves 234 may have a length that extends along a portion of the length of the sleeve 230 (e.g., 1 / 2 of the length of the sleeve 230). As another example, although Figure 7-9 The sleeve connector 200 has six grooves 234, but the sleeve connector 200 can have any number of grooves. As yet another example, although Figure 9 The geometry of the groove 234 shown is basically trapezoidal, but the groove 234 can have any desired geometry (e.g., rectangular, semi-circular, triangular).

[0038] The sleeve 230 also includes a collar 250 disposed adjacent to the second fluid port 232. The collar 250 may be sized and shaped to extend radially outward beyond the outer surface 236 of the sleeve 230, thereby providing a retaining wall 252. The retaining wall 252 provides a retaining surface to help retain the adhesive in the groove 234 during adhesive application and assembly of the sleeve connector 200. The collar 250 may be configured to provide a greater frictional engagement with the tube 20 relative to the frictional engagement between the outer surface 236 of the sleeve 230 and the tube 20. Furthermore, the collar 250 may act as various barbs to provide additional resistance to movement of the tube 20 once it is engaged with the sleeve 230. The sleeve 230 may also include a tapered portion 231 disposed at the leading edge of the sleeve 230. The tapered portion 231 provides an inclined surface to allow the sleeve 230 to slide more easily into the end portion 21 of the tube 20. The dimensions (e.g., outer diameter) of the collar 250 can be configured to provide the desired level of glue retention and barb resistance. Although Figure 7-9Not shown, but the sleeve connector 200 may also include the sleeve member as described above with respect to the sleeve connector 100. In various aspects of this disclosure, the groove 234 stops at the retaining wall 252 of the collar 250 and before the beginning of the tapered portion 231, thereby providing a smooth outer surface for the tapered portion 231. In various aspects of this disclosure, the groove 234 may extend into the tapered portion 231. For example, the collar 250 may be disposed around the outer surface 236 of the sleeve 230, and the groove 234 may extend below the collar 250 and into the tapered portion 231.

[0039] Any or all of the elements of the aforementioned sleeves 130 and 230 can be used in any device (e.g., pump tube connectors, tube connectors of infusion kit components 40, 50, and 70). For example, the inlet port 74 of the Y-joint 70 shown in FIG. 2 can be provided as sleeve 130 or sleeve 230, thereby providing the correspondingly increased retention features as described above. Similarly, any male protrusion of an infusion device (such as an infusion pump or infusion kit component) intended to mate with a tube end (e.g., end portion 21) can be configured or provided as sleeve 130 or sleeve 230.

[0040] In one or more embodiments of this disclosure, the sleeve connector includes a housing having a first fluid port disposed at a first end of the housing and a stop surface disposed at a second end of the housing. The sleeve connector also includes a sleeve extending from the stop surface and configured to be inserted into a tube.
