Claims (4)

  1. 2. A luer lock connection device according to Claim 1, wherein the sleeve-
    retaining member comprises an outwardly extending ring carried by the tubular body, the rear portion of the sleeve having a smaller internal diameter than the external diameter of the sleeve-retaining member, so that the sleeve-retaining member prevents forward movement of the rear portion of the sleeve past a predeterntined point.

    THE PATENT OFFICE 5 August 1982 Bas 91669113 1 1 1 1 GB 2 089 921 A 1 SPECIFICATION Luer lock connection device The present invention concerns an improved luer lock connection device. Luer lock connectors are known in which the male luer connector carries an internally threaded outer sleeve to establish a cooperating threaded engagement with the female luer connector which is externally threaded or carries a radially extending flange.
    Some prior art luer lock connection devices have been found difficult to use because once the connection is made, disengagement of the male luer connector from the female luer connector is extremely difficult.
    The present invention provides a luer lock connection device which comprises a male luer connector comprising a tubular body having a front end portion adapted for insertion into a female luer connector, a rear end portion adapted for coupling to tubing; and a main portion between the front end and rear end portions and separated from the front end portion by a sleeveretaining member; a sleeve having a rear portion slidable along said main portion and having a front portion which is internally threaded and adapted for engaging an outer flange of the female luer connector; the rear portion of the sleeve having a slot to render said rear portion significantly resilient.
    Preferably, the tubular body carries an outwardly extending flange rearwardly of the main portion and cooperative with the slot to prevent relative rotation of the sleeve and the tubular body when the flange is within the slot.
    In the illustrative embodiment, the sleeve retaining member comprises an outwardly extending ring carried by the tubular body. The rear portion of the sleeve has a smaller internal diameter than the external diameter of the outwardly extending ring so that the outwardly extending ring prevents forward movement of the rear portion of the sleeve past a predetermined point.
    Reference is now made to the accompanying drawings, wherein:- Figure 1 is a perspective view of a luer lock connection device, constructed in accordance with the present invention, together with a female luer connector; Figure 2 is a cross-sectional elevation of the 115 device of Figure 1; and Figure 3 is an enlarged cross-sectional elevation of a sleeve of the device of Figures 1 and 2 and its connection to the female luer connector.
    Referring to the Figures, there are shown in Figure 1 a luer lock connection device, having a male luer connector 10 and a sleeve 20, and a female luer connector 12. Female luer connector 12 is of the type in which the main body 14 has a bore 16 and a flange 18 surrounds bore 16 and extends radially from main body 14. The length of flange 18 is such that it threadedly cooperates with internal threads of the sleeve 20. Plastics tubing 22 is secured to main body 14 by pressure and solvent sealing as is well-known in the art.
    Male luer connector 10 has a tubular body 24 which defines a bore 26 and comprises a front portion 28 contiguous with front end 30 which is adapted for insertion into bore 16 of female luer connector 12. The external surface of front portion 28 is dimensioned so as to provide a snug pressure fit within bore 16.
    Tubular body 24 also includes a main portion 32 that is separated from front portion 28 by a sleeve-retaining member 34. In the illustrative embodiment, sleeve-retaining member 34 comprises an outwardly extending ring carried by tubular body 24.
    The rear end 36 of tubular body 24 is coupled to plastics tubing with a pressure fit and with solvent bonding. A pair of opposed flanges 38, 39 extend outwardly from tubular body 24 adjacent rear end 36 for cooperation with slots 40 defined by sleeve 20 as discussed below.
    Sleeve 20 has a front portion 42 that is internally threaded for threaded cooperation with flange 18, and a rear portion 44 that has a smaller internal diameter than the external diameter of ring 34. Thus, ring 34 serves to prevent sleeve 20 from moving forward past the position illustrated in Figure 2.
    Rear portion 44 has a rear end portion 46 with an inner surface 48 that forms a wiper seal against the surface of main portion 32. Main portion 32 is tapered outwardly in the forward direction so that as sleeve 20 moves forwardly, there will be increased compression between inner surface 48 and the surface of main portion 32. This structure provides an excellent fluid seal.
    As stated above, rear portion 44 of sleeve 20 defines slots 40 which, as illustrated most clearly in Figures 1 and 3, have their widest portion at the rear end 46 of the rear portion 44 and taper inwardly forwardly. These generally V-shaped slots aid in giving the sleeve the proper resilience for movement along main portion 32. In addition, when sleeve 20 is unscrewed from flange 18, flanges 38 and 39 will catch within slots 40 and relative rotation between sleeve 20 and tubular body 24 will be prevented. Prevention of such relative rotation is significant because otherwise it would be extremely difficult to remove male luer connector 10 from female luer connector 12 once the luer connectors are coupled together.
    It is desirable that the luer lock connection device be formed in a plastics moulded construction. Sleeve 20 may carry a pair of wings for enabling grasping by the operator for easy insertion and removal of the male luer connector 10 from the female luer connector 12.
    It can be seen that inner surface 48 forms a wiper seal or a ring seal which is compressed by the forward movement of sleeve 20 along main body portion 32. The seal formed by inner surface 48 is mated to sleeve 20 so that the sleeve is selfcentering. By use of the aforesaid structure an excellent fluid-tight seal is provided, with the sleeve and tubular member having cooperating means to prevent relative rotation when GB 2 089 921 A 2 disconnection of the block is desired.
    Performance of the invention described above involves use of the invention described and claimed in U.K. patent specification No. 2055166.
    CLAIMS 1. A luer lock connection device which comprises: a male luer connector comprising a tubular body having a front end portion adapted for insertion into a female luer connector, a rear end portion adapted for coupling to tubing; and a main portion between the front end and rear end portions and separated from the front end portion by a sleeve-retaining member; a sleeve having a rear portion slidable along said main portion and having a front portion which is internally threaded 35 and adapted for engaging an outer flange of the female luer connector; the rear portion of the sleeve having a slot to render said rear portion significantly resilient.
  2. 2. A luer lock connection device according to Claim 1, wherein said tubular body carries an outwardly extending flange rearwardly of said main portion, said flange and slot being cooperative to prevent relative rotation of said sleeve and tubular body when the flange is within said slot.
  3. 3. A luer lock connection device according to Claim 2, wherein the sleeve-retaining member comprises an outwardly extending ring carried by the tubular body, the rear portion of the sleeve having a smaller internal diameter than the external diameter of the sleeve-retaining member, so that the sleeve-retaining member prevents forward movement of the rear portion of the sleeve past a predetermined point.
  4. 4. A luer lock connection device according to Claim 1, 2 or 3, wherein said slot has its widest portion at the rear end of said rear portion and tapers inwardly away from said rear end.
