Definitions

  • the disclosed embodiments relate to a medical connection device, and more particularly, to a male and female connection device, which can be used in conjunction with fluid administration, such as intravenous fluid administration.
  • Luer connections are the typical mechanisms for attaching various medical devices such as syringes, catheters, and intravenous lines to one another. These lines are then generally connected to a patient via a catheter. In a typical luer connection, male and female connectors are mated together to form and secure the connection. Luer connections are widely used in the medical industry because they are quick and easy to assemble.
  • connection device comprising a male connector, which includes a body with a distal end and a proximal end, and a projection.
  • the projection has an opening located at a distal end of the projection. The opening is in fluid communication with a fluid passageway located within the body.
  • the projection has a length Ll .
  • the connection device further comprises a female connector, comprising a body, a distal end, and a proximal end. A fluid passageway is located within the body.
  • the female connector includes a member perpendicular to the fluid passageway within the body and positioned a length L2 from the proximal end of the female connector and blocking insertion of the projection past the member.
  • the length Ll is approximately equal to L2, such that only a male connector with a projection having the length Ll is fully insertable into the female connector. This will prevent the insertion of typical male connectors.
  • connection device comprising a male connector including a projection with a slot.
  • the connection device also includes a female connector comprising a post perpendicular to the fluid passageway within the body. The post is configured to engage the corresponding slot of the projection during insertion of the male connector into the female connector and block insertion of a projection of a male connector without a slot into the female connector.

  • connection device comprising a male connector, which includes a body with a distal end and a proximal end, and a projection from the body having an opening located at a distal end of the projection.
  • the opening is in fluid communication with a fluid passageway located within the body.
  • the projection has a length Ll .
  • the connection device further comprises a female connector comprising a body with a distal end and a proximal end, a fluid passageway located within the body, and a member perpendicular to the fluid passageway within the body.
  • connection device comprising a male connector including a projection with a slot.
  • the connection device also includes a female connector comprising a post perpendicular to the fluid passageway within the body.
  • connection device comprising a male connector including a slot.
  • the connection device also includes a female connector comprising a post.
  • the post is configured to engage the corresponding slot of the male connector.
  • the post is located so as to only allow full insertion of the dedicated male connector into the female connector.
  • Other disclosed embodiments provide a connection device comprising a male connector, which includes a body with at least one prong.
  • the male connector further includes a tubing pocking with standoffs. The standoffs are configured to permit fluid to flow through a periphery path of the tubing pocket.
  • the male connector also includes at least one attachment piece.
  • the connection device also comprises a female connector, including a body with at least one groove. The groove corresponds to the prong of the male connector, and aligns the male connector upon its insertion into the female connector.
  • the female connector includes a ridge, which cooperates with the attachment piece of the male connector to secure the male connector within the female connector.
  • the female connector further includes a tubing pocket with standoffs.
  • FIG. 1 shows a connection device 10.
  • the device comprises a male connector 12, that includes a body 14.
  • the body 14 has a distal end 16 and a proximal end 18.
  • distal refers to the direction toward the patient.
  • Proximal refers to the direction away from the patient, or toward the syringe or other collection or dispensing device, such as an intravenous (IV) bag.
  • the male connector 12 has a generally cup-shaped design, as seen in FIG. 1, with a recess 21 configured to mate with a female connector.
  • a projection 19 extends within the recess 21 towards the distal end 16 of the body 14.
  • the projection 19 is received within a mating portion of a female connector, as will be further described.
  • the projection 19 includes an opening 20 in fluid communication with a fluid passageway 22. Thus, fluid may flow unobstructed through the fluid passageway 22 and out of the opening 20.
  • the male connector 12 is configured to mate securely with the female connector 26 depicted in FIG. 1 , with other male connectors not being able to be securely mated.
  • the connection device 10 further comprises a female connector 26.
  • the female connector 26 includes a body 28.
  • the body 28 has a distal end 30 and a proximal end 32.
  • a fluid passageway 34 is located within the body 28.
  • the male connector 12 of FIG. 1 may be inserted into the female connector 26 such that the fluid passageways 22, 34 are aligned with one another.
  • the fluid passageways 22, 34 are sized to accommodate typical sized intravenous tubing. However, other types of male connectors will not be able to be fully inserted into the female connector 26.
  • the female connector 26 includes a member 36.
  • the member 36 is fixedly positioned perpendicular to the fluid passageway 34 of the female connector 26.
  • the member 36 is shallowly located, such that it is not immediately proximate to the distal end 30 of the female connector 26.
  • the member 36 is positioned within the fluid passageway 34 so that only the dedicated male connector 12 may be fully inserted into the female connector 26, as shown in FIG. 2.
  • the length Ll of the projection 19 is substantially equal to the length L2 between the proximal opening 23 of the female connector 26 and the member 36.
  • Typical male connectors include projections that are longer, such that the projections extend to the distal end of the male connector.
  • FIG. 3 shows an attempt to insert a typical male luer into the female connector 26.
  • the member 36 will prevent the connectors 12, 26 from properly mating.
  • a fluid-tight seal may be formed once the male and female connectors 12, 26 are secured. The member 36 ensures an incorrect male connector cannot be fully inserted, which could be a potentially fatal situation for the patient.
  • the male connector 12 includes a threaded locking hub 42 and the body 28 of the female connector 26 is also threaded.
  • the locking hub 42 may be screwed onto and around the female connector body 26, securing the male and female connectors 12, 26.
  • the male connector 12 includes a slot 38.
  • the slot 38 may be rotatably cut-out around the exterior of the body 14 of the male connector 12.
  • the female connector 26 includes a post 40, which may be cylindrically shaped, or may assume other shapes configured to interact with the slot. The post 40 is configured to engage the slot 38 of the male connector 12, upon insertion of the male connector 12 into the female connector 26.
  • FIGS. 5-7 as the male connector 12 is inserted into the female connector 26, the post 40 engages the end of the slot 38.
  • the post 40 is shallowly located on the female connector 26. The location of the post 40 prevents full insertion and engagement of a typical male luer. The location of the post 40 is such that it engages the slot 38 when the male connector 12 is only partially inserted, shown by FIG. 5.
  • the male connector 12 is then rotated as it is fully inserted into the female connector 26, such that the post 40 travels up and further into the slot 38, shown in direction A in FIGS. 6 and 7.
  • FIGS. 8-10 show a connection device 10 comprising the male connector 12, in which the body 14 has at least one prong 44. As shown in FIG.
  • the male connector 12 includes a tubing pocket 46 with standoffs 48.
  • the standoffs 48 are configured to permit fluid passing through the male connector 12 to flow through a periphery path 50 of the tubing pocket 46. Thus, the fluid will take a more direct path through the male connector 12.
  • the male connector 12 further includes at least one attachment piece 52.
  • the attachment piece 52 may be a snapping piece 52 of a snap-fit connection.
  • the connection device 10 further includes the female connector 26, shown in FIGS. 11-12, in which the female connector 26 includes at least one groove 54 (FIG. 12).
  • the groove 54 is formed between a plurality of ribs 66 located within the female connector 26.
  • the groove 54 corresponds to the prong 44 of the male connector 12.
  • the male connector 12 comprises a plurality of prongs 44 that engage a plurality of corresponding grooves 54.
  • the presence of the prong 44 and groove 54 prevents the connection device 10 from being compatible with typical ISO male and female luer connectors. Thus, the connection device ensures that an incorrect connector, and line, will not be attached to a patient.
  • the female connector 26 also includes a ridge 56, shown in FIGS. 11 and 12.
  • the ridge 56 cooperates with the snapping piece 52 of the male connector 12, seen in FIG. 8.
  • the snapping piece 52 snaps onto the ridge 56. This secures the connectors 12, 26 together and may form a fluid-tight seal.
  • the bodies 14, 28 of the male and female connectors 12, 26 are generally cylindrically shaped such that they may easily be mated. However, the bodies 14, 28 may be shaped in other geometries as well.
  • the female connector 26 further includes a tubing pocket 58 with standoffs 60.
  • the tubing pockets 46, 58 are sized to receive typical sized intravenous tubing.
  • the standoffs 48, 60 prevent the tubing within the tubing pockets 46, 58 from forming a seal at the base of the tubing pocket. This would prevent flow of the fluid through the connection device 10 and to the patient or fluid receptacle.
  • the male connector 12 may also include at least one wing 62, and the body 14 may have a notch 64.
  • the wing 62 is shaped to extend outwardly from the body 14, as seen in FIGS. 8-10.
  • the notch 64 provides for independent flexibility of the wing 62.
  • Compressing the wing 62 disengages the snapping piece 52 of the male connector 12.
  • the notch 64 allows the wing 62 to flex open and away from the body 14 of the male connector 12. This allows for removal of the male connector 12 from the female connector 26. It is contemplated that a plurality of wings 62 may be included on the male connector 12.
  • the attachment piece 52 of the male connector 12 may be threaded, and the ridge 56 of the female connector 26 may be threaded.
  • the male connector 12 may be screwed onto the female connector 26.
  • the prong 44 of the male connector 12 may be circumferential.
  • the prong 44, shown in FIG. 16 may be hollow inside its circumference such that it may still engage the groove 54 of the female connector 26.
  • the groove 54, shown in FIG. 15, of the female connector 26 may then also be circumferential in shape so that it may receive the prong 44 of the male connector 12.
  • the attachment piece 52 of the male connector 12 may be threaded, and the ridge 56 of the female connector 26 may be threaded.
  • the male connector 12 may be screwed onto the female connector 26, as shown in FIG. 16.
  • a connection device having a male connector and a female connector is provided.
  • the female connector will only accommodate the dedicated male connector, thereby prohibiting a misconnection with the wrong male connector.
  • a member prohibits male connectors other than a dedicated male connector from being fully inserted into the female connector.
  • a post prohibits male luers, other than a dedicated male connector including a slot, from being fully inserted into the female connector.
  • a series of prongs in the male connector and corresponding grooves in the female connector ensure the proper connection. Once the male connector is inserted and secured within the female connector, a fluid-tight seal is formed between the male connector and the female connector. The disclosed embodiments therefore prevent the misconnection of male and female luer connectors without requiring medical personnel to take additional precautionary steps.
