Herbert Mittleman ABSTRACT OF THE DISCLOSURE
A luer lock connection device in which a male luer connector includes an outer sleeve that is slideable up a tapered wall so that compression between the outer sleeve and the tapered wall increases as the outer sleeve moves forwardly. An outwardly extending flange is carried by the body of the male luer connector for coop-eration with the outer sleeve, to enable the outer sleeve to be unscrewed from a female luer connector with-out relative rotation of both the main portion of the male luer connector and the outer sleeve.
Description
39~i6 BACE~GROUND OF THE INVENTION
The present invention concerns an improved luer lock connection devlce.
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 to leak and this could result in air embolism or could create contamination problems. Certain 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 ~he female luer connector is extremely difficult.
It is an object of the present invention to provide a luer lock connection device which has a fluid-type connection.
Another object o~ the present invention is ~o provide a luer lock connection device which enables clear inspection of the connection~
A further object of the present invention is to provide a luer lock connection device in which the mating parts are preloaded prior to locking.
A still further object of the present invention is to provide a luer lock connection device which is simple in construction and is efficient to manufacture.
Other objects and advantages of ~he present inven-tion will become apparent as the description proceeds.
~.;, ~L1339E;6 SUMMARY OF THE INVENTION
In accordance wi-th the present invention, a luer lock connection device is provided which includes a male luer connector comprising a tubular body and defining a bore with a front end thereof adapted for insertion into a female luer connector and a rear end thereof adaptecl for coupling to tubing. The tubular body has a front portion that is contiguous with the front end and a main portion that is separated from the front portion by a sleeve-retaining member. A sleeve is provided and is slidable along the main portion. The sleeve also has a front portion that is internally threaded and is adapted for receiving a female luer connector with external threads or an outer flange. The main portion of the tubular body is tapered outwardly in the forward direction. In this manner, increased compression between the rear portion of the sleeve t and the main portion of the tubular body occurs as the sleeve is moved forwardly.
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 por-tion of the sleeve past a predetermined point.
Pg/ ~ _ 3 _ ~`33~
In the illustra~ive embodiment, the rear portion of the sleeve defines a pair of opposed slots to render the sleeve's rear portion significantly resilient. The tubular body carries a pair of outwardly extending flanges rearward of the main portion, with the flanges and slots being cooperative to prevent relative rotation of the sleeve and tubular body when the flanges are within the slots.
A more detailed explanation of the invention is provided in the following description and claims, and is illustrated in the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIGURE 1 is a perspective view of a luer lock connection device constructed in accordance with the principles o the present invention;
FIGURE 2 is a cross-sectional elevation of the male luer connector of the device of Figure l; and FIGURE 3 is an enlarged cross-sectional elevation of the sleeve carried by the male luer connector of Figures 1 and 2 and its connection to the female luPr connector.
DETAILED DESCRIPTION OF THE
ILLUSTRATIVE EMBODIMENT
Referring to the figures, a luer lock connec~ion device is shown therein comprising a male luer connec~or 9 ~339~i~
10 and a female luer connector 12. Fe~ale luer connecLor 12 is of the type in which the ~.ain body 14 defines 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 the internal threads of a sleeve 20 carried by male luer connector 10. Plastic tubing 22 is fastened 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 con-tiguous 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 plastic 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 ~.~.339~
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.
The increased compression ensures that sleeve 20 will not engage flange 18 until front portion 28 is first inserted into bore 16 of female luer connector 12. In cer-tain prior art luer locks, the coupling of the locking sleeve to the female connector may occur notwithstanding the lack o~ a secure fluid~tight connection between the male luer and the ~emale luer. Any leakage may cause air embolism. By utilizing an increasing compressive resistance in the present invention, the operator is forced to close the male luer-female luer connection securely before the sleeve 20 canthreadedly engage flange 18.
As stated above, rear portion 44 of sleeve 20 de-fines 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 gener-ally V-shaped slots aid in giving the sleeve the proper resil-ience for movement along main portion 32. In addltion, 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 Pg/~ h - 6 -~33~
female luer connector 12 once the luer connectors are coupled together.
It is desirable that the luer lock connection device be formed in a plastic molded 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 move-ment o~' sleeve 20 along main body portion 32. The seal formedby lnner surface 48 is mated to sleeve 20 so that the sleeve is self-centering.
Although an illustrative embodiment of the invention has been shown and descxibed, it is to be understood that various modifications and substitutions may be made by those skilled in the art without departi~ng from the novel spirlt and scope of the invention.
