Definitions

  • the invention generally relates to connectors and, in particular, to a medical connector for connecting a plurality of drainage tubes to a single outlet tube.
  • One particular application in which it is desirable to connect several tubes to a single tube is in orthopaedics.
  • a plurality of tubes are commonly used to collect blood and other fluids from various locations around a wound site following orthopaedic surgery.
  • the tubes are typically connected by a series of connectors to a single tube which drains into a collection device.
  • Y-shaped connectors are commonly used to connect two drainage tubes to a single outlet tube.
  • a number of Y-shaped connectors are often used in combination to connect the various drainage tubes to the outlet tube.
  • the number of connections necessary to couple the drainage tube to the outlet tube increases the time needed by attending medical personnel to set up the device. Further, the number of Y-connections required makes the device set-up cumbersome.
  • the multiplicity of connections also increases the risk of disconnection of tubes which could result in a medical emergency.
  • the invention is an improved medical connector which overcomes at least the limitations noted above.
  • the present invention is directed to a device comprising a main body portion integrally connected with at least three branch portions.
  • the main body portion defines a main fluid passageway therethrough, while the branch portions each define branch fluid passageways in fluid communication with the main fluid passageway.
  • the main body portion has a central longitudinal axis therethrough.
  • Each branch portion comprises a first section having a longitudinal axis which diverges from the central axis of the main passageway and a second section having a longitudinal axis which is substantially parallel to the main axis.
  • the second sections of the branch portions are symmetrically oriented about the main fluid passageway. Further, the second section of each branch passageway is coplanar with the main fluid passageway.
  • the diameter of the branch passageways continuously decreases along the length thereof to facilitate connection with drainage tubes of varying diameter.
  • a device in accordance with the invention comprises a body portion defining a main passageway having a longitudinal axis to allow for passage of fluid therethrough.
  • the device includes at least three extended body portions, wherein each extended body portion defines an extended passageway to allow for the passage of fluid through each of the extended body portions.
  • Each extended body portion comprises a first section having a longitudinal axis which diverges from the longitudinal axis of the main passageway and a second section having a longitudinal axis which is parallel to the central longitudinal axis of the main passageway.
  • the extended passageways have a proximal end connected to the main fluid passageway and distal end opposite the proximal end.
  • the passageways may have a first diameter at the proximal end and may decrease to a second diameter at the distal end.
  • the distal ends of the passageways may include a removable seal.
  • Figure 1 is a side view illustrating a connector in accordance with the present invention
  • Figure 2 is an end view of the connector illustrated in Figure 1. Detailed Description of the Invention
  • any reference to either direction or orientation is intended primarily and solely for purposes of illustration and is not intended in any way as a limitation of the scope of the present invention. Also, the particular embodiments described herein, although being preferred, are not to be considered as limiting of the present invention. Furthermore, like parts or elements in the various drawings hereto are identified by like numerals for ease of reference.
  • the connector 10 is preferably formed of a flexible plastic material and comprises a main body portion 12 and a plurality of extended body portions, generally designated 14.
  • the main body portion 12 of the connector 10 defines a main fluid passageway 16 therethrough having a central longitudinal axis 18.
  • the connector 10 includes an open end 20 adjacent the main body portion 12 into which a single outlet tube (not shown) is inserted, such that the outlet tube is in fluid communication with the main fluid passageway 16.
  • the extended body or branch portions 14 of the connector 10 define extended or branch fluid passageways 22 through the connector 10 which are in fluid communication with the main passageway 16.
  • the extended body portions 14 include an open proximal end 24 which is connected to the main fluid passageway 16 and a distal end 26, opposite the proximal end 24, into which a plurality of drainage tubes (not shown) may be inserted so as to be in fluid communication with the extended fluid passageways 22 therethrough.
  • Each extended fluid passageway 22 comprises a first section 30 having a longitudinal axis 32 which diverges from the central longitudinal axis 18 of the main fluid passageway 16 and a second sections 34 having a longitudinal axis 36 which is substantially parallel to the central longitudinal axis 18 of the main passageway 16.
  • the longitudinal axes 32 of the first sections 30 of the extended passageways 22 diverge from the longitudinal axis 18 of the main passageway 16 at an angle of approximately 10°.
  • the second sections 34 of the extended portions 14 of the connector 10 are oriented symmetrically about the central axis 18 of the main passageway 16. Further, the second sections 34 of each extended portion 14 is coplanar with the main body portion 12.
  • the connector 10 includes four extended portions 14 having second sections 34 which are oriented symmetrically in a rhomboidal configuration about the central axis 18 of the main passageway 16. As shown in Figure 1 and Figure 2, the diameter of the extended fluid passageways 22 continuously varies along the length of the passageways from the proximal end 24 to the distal end 26.
  • the diameter of the extended fluid passageways 22 gradually decreases from a first diameter of approximately .25 inches at the proximal end 24 to a second diameter of approximately .09375 inches at the distal end 26.
  • the extended fluid passageways 22 are able to accommodate the insertion of drainage tubes of various diameters along the length thereof.
  • markings are provided at predetermined intervals on the exterior surface along the length of the extended fluid passageways 22 to indicate the connection points for standard size tubes.
  • the markings are provided at three locations on the extended fluid passageways 22 to indicate connection points for 1/8", 3/16", and 1/4" tubing, however, those skilled in the art will recognize that markings could be provided at other locations on the passageways as desired.
  • the distal ends 26 of the extended fluid passageways 22 are formed with rounded tips 40 which are removed on an as needed basis when tubes are connected thereto.
  • the outlet tube is first connected to the main body portion 12 by inserting the outlet tube into the open end 20 of the connector 10.
  • an extended body portion 14 is selected and cut to the appropriate size diameter as indicated by the markings on the external surface thereof.
  • the drainage tube(s) is then inserted into the opening in the distal ends 26 of the extended portions 14 of the connector 10.
  • the distal ends 26 of the unused extended body portions 14 of the connector 10 remain covered by the sealed tips 40 to prevent dust, dirt, or other contaminants from entering the connector and becoming mixed with the fluid carried therein.
  • Blood and fluid may be drained from the wound site using well-known suction or gravity drainage techniques. Blood and fluid draining from the wound site through the drainage tubes enters the second sections 34 of the extended fluid passageways 22. The fluid from the drainage tubes then flows into the first sections 30 of the extended passageways 22, emptying into the main passageway 16. From the main passageway 16, the fluid flows into the outlet tube attached thereto for removal into an associated collection device.
  • the substantially parallel orientation of the extended fluid passageways 22 relative to the main passageway 16 provides a substantially parallel flow path from the drainage tubes through the connector 10 into the outlet tube. In this manner, undesirable partial pressures which can result from sharp angles in the flow path are minimized.

Abstract

Le dispositif comprend une partie principale (16) définissant un passage principal de liquide et une pluralité de parties étendues (14) définissant des passages de liquide étendus en communication fluide avec le passage principal. La partie principale possède un axe longitudinal central. Les parties étendues comprennent une première section (30) possédant un axe longitudinal divergeant de l'axe longitudinal principal, ainsi qu'une deuxième section (34) possédant un axe longitudinal sensiblement parallèle à l'axe longitudinal. En fonctionnement, on introduit le tube de sortie dans une extrémité ouverte de la partie principale et on insère les tubes de drainage dans les extrémités des parties étendues. Le liquide s'écoule depuis les tubes de drainage et les passages de liquide étendus dans le passage de liquide principal, ainsi que dans le tube de sortie fixé auxdits passages, selon un trajet d'écoulement sensiblement parallèle.
