Abstract

IMPROVED TELESCOPING-TYPE CONNECTOR

INVENTOR: Walter L. Carpenter ABSTRACT OF THE DISCLOSURE

A telescoping-type connector comprising outer and inner telescoping members, the inner telescoping member defining an outer circumferential groove, and adapted to sealingly fit in telescoping relation within an aperture of the outer telescoping member. The outer telescoping member includes retention means for releasably projecting into the outer circumferential groove, to retain the inner and outer members in the desired sealing, tele-scoping relation. In accordance with this invention, the inner telescoping member defines, between the circumferen-tial groove and the forward end of the inner member relative to the outer member, a recessed portion on its outer sur-face for facilitating molding and the like. Ribbed members are positioned within the recessed portion, to prevent the retention means from projecting therein and providing in-adequate lacking of the connector.

Description

3 ~ ~ ~

BACKG~OUND OF THE INVENTION

Telescoping-type connectors for fluid lines and the like are well-known, one variety of such connector being sold by the Hansen Manu~acturing Company of ~leveland Ohio, known as the "Hansen Connector". Examples of such connectors are illustrated in U.SO Patents 2,518,542;
2,761,469; 3,245,423, and 3,351,362.
A typical embodiment of this type of connector utilizes inner and outer telescoping members in which the inner telescoping member sealingly fits within an aperture of the outer kelescoping member to make the desired fluid line connection. The connection is held in retention by means of several spaced, metal balls which project through the wall of the aperture of the outer telescopirlg member, to fit into an outer circumferential groove of the inner member for retention thereof. The balls are held in their inwardly projecting, retaining position by an outer sleeve positioned on the outer membex which presses the balls inwardly. To couple and decouple the connector, the outer sleeve is axially displaced to Eree the balls so that they may retract outwardly, in which position the inner telescop-irlg member may slide into or out of the outer member.
The telescoping-type connectors are suitable for use in many different fields, including the field of dispos-able medical devices such as dialyzers or oxygenators forblood. While in the past the telescoping~type connectors have been made of metal such as brass, stainless steel or the like, it becomPs desirable in the case of disposable 2 - ~c devices such as those mentioned ahove to provide a telescop-ing-type connector in which at least one of the telescoping members, typically the inner member, is made of an inexpen sive, molded plastic, so that the connector member does not have to be salvaged following use of the disposable device.
However, it has been found that some difficulties of molding such a connector member have been encountered.
For example, it is often difficult to mold the inner tele-scoping member of a given size, because the relatively thick section of plastic between its outer circumferential groove and its forward end, which should be of precise dimensions, is subject to warpaye, distortion, and sinkiny as the thick section of material cools. This results in a substantial number of parts wh ch do not meet desired manufacturing specifications ~ecasue of their tendency to leak.
Howevert if one removes plastic from the outer portion of the thick section, a second circumferential groove can be formed which acts in a manner similar to the func-tioning circumferential groove intended for receiviny the balls oE the outer telescoping member. If the second groove does so receive the retaining balls, the connector can ass~me an apparently locked configuration without being actually locked in sealing condition, so that leakage takes place.
The invention of this application provides an inner telescoping member in which the thick plastic section adjacent the forward end can be reduced to ~ave plasticf and to avoid the undesirable distortions o the dimensions which often take place in molded, thick plastic sections, while at the same time reducing the possibility o falsely locked ~ Ç3~J~ ~

configuration which does not seal, because the retaining balls of the outer telescoping member are projecting lnto the wrong area of the inner telescoping member.
Accordingly, a disposable, telescoping-type connec-tor member is provided in which the advantages of the connec-tor can be combined with disposable equipme~t.

DESCRIPTION OF THE INVENTION
In accordance with this invention, a telescoping-type connector comprises outer and inner telescoping members.
The inner telescoping member deine~ an outer circumferential groove, and is adapted to sealingly fit in telescoping relation within an aperture of the outer telescoping member.
The outer telescoping member includes retention means for releasably projecting into the outer circumferential groove of the inner member, to retain the inner and outer members in their desired sealing, telescoping relation.
In accordance with this invention, the inner tele-scoping member defines, between the circumferential groove and the forward end of the inner member relative to the outer member, a recessed portion on its outer surface. Rib members are positioned within the recessed portion, the rib ~ members being positioned and proportioned to prevent the re-s tention means from projecting into the recessed portion.
Accordingly, the desired recessed portion can be provided in the inner telescoping member to save material and weight in the inner member, and also to avoid the mol~ing problems descri.bed above, to adapt the telescoping connector concept to inexpensive, molded plastic parts without under-going the danger of providing a falsely locked configuration for the connector, which could permit leakage.

~P7~L

Preferably, the retention means are a pluraliky of radially arranged balls residlng in the plurality of aper-tures in thP outer telescoping member, with the balls being adapted to be pressed inwardly into retaininy relation with the outer circumferential groove of the inner -t~lescoping member by means of a sliding sleeve carried by the outer telescoping member. The sliding sleeve is spring-biased in the ball-retaining position, but can be axially moved away from the balls to allow them to be moved outwardly, to permit insertion and removal of the inner member into the outer member.
The rib members are preferably longitudinally positioned a1ong the inner telescoping member, and do not have to equal the number of ball members present, since the connector typically cannot close if even one of the ball members is held out of position by a rib. Preferably, the ribs are so oriented that at least two ball members are held in a radially outward position at any angular relation-ship of the outer and inner telescoping members. Under this circumstance, the outer retaining sleeve for the ball members cannot move into its closed position, which provides a clear indication for the user that the connector is not closed.
Referring to the drawings, Figure 1 is an eleva-tional view of the connector of this invention in closed and locked position.
Figure 2 is an elevaticnal view of the same connec-tor of this invention, in which the outer and inner telescop-ing members are in telescoping but unlocked configuration.
Figure 3 is a longitudinal sectional view of the connector in the configuration of Figure l.

~3t7~

Figure 4 is an elevational view, taken partly in longitudinal section, showing the separated connector mem-bers about to be brought together.
Figure 5 is an elevational view, taken partly in s longitudinal section, showing th~ connectors in the configur-ation of Figure 2.
~ igure 6 is a transverse sectional view taken along line 6-6 o Figure 5.
Referring to the drawings, a telescoping-type connector is shown comprising outer telescoping member 10 and inner telsscoping member 12. Both members define a bore 14, 16 through which fluid may pass in sealed relation through the closed connectors in the configuration of Fiyure 1.
The ends 18, 20 of the respective connector members 10, 12 may be attached to appropriate tubing or to a device such as a dialyzer or oxygenator. For example, connector 10 may com-municate with a conduit for dialysis solution ~rom a dialysis solution delivery machine of conventional design, while connec tor member 12 communicates at its end 18 with flexible tubing leading to a dialyzer, ~or example a hollow fiber dialyzer, a coil dialyzer, or a plate-type dialyzer. Also, connectors 10, 12 may communicate with tubing leading between a blood oxygen-ator or an artificial kidney, while the other connector com-municates wtih blood flow tubing which leads to the artery or vein of a patient. Alternatively, one or both of connec~or members 10, 12 may be integrally molded to the outer wall of a ~ device such as a dialyzer or oxygenator.
; Connector 12 in particular may be made of molded plas-tic to define an outer circumferential groove 20 r which begins and terminates wikh longitudinally positioned angled faces 22,
3~

24, Between outer circumferential groove 20 and the forward end 26 of inner telescoping member 12 is definecl an inwardly recessed portion 28 which is crossed by ribs 30, which are of generally equal heigh~ to the radially outwardmost portions of face 24O
Ribs 30 can be seen to be parallel to each other and to extend in a longitudin~l manner across recessed portion 28, and are, in the particular embodiment shown, disposed about connector 12 at 90 position angles to each other (Figure 6), there being four ribs 30 present. However, other numbers and configurations of the ribs are contemplated to be within the scope of this invention, including annular, circumferential ribs extending about connector 12.
Adjacent the forward end 26 of inner connector member 12, an angled, annular sealing surface 32 is defined.
As shown in Figure 3, connector membe~ 12 can fit in telescoping relation within aperture 34 of connector mem-ber 10. In the sealed relation as shown in Figure 3, seal-ing surface 32 bears against O ring 36, which may be mounted within aperture 34, when the sealed position is achieved.
Outer connector member 10 defines an array of ball members 38 residing in pockets 40, which are open to the interior of aperture 34 as shown, and proportioned so that ball members 38 c~n be forced partially inwardly to aperture 25 3~, when inner telescoping connec~or member 12 is properly positioned to reside in outer circumferential groove 20 so as to lock the connector. The balls are held in their locking position by sleeve 44, which is biased by spring 41 into its position in which inner surface 42 of sleeve 44 bears against the outer portion of balls 38, holding them in a radially -inward position in which they project into groove 20 for sealing 3~2~

retention thereo~.
When it .is desired to ei-ther insert or remove the inner connector me~ber 12 from the outer member 10, sleeve 44 is merely moved axially against the action of coil spring 41 until the balls 38 are released from engagement by sleeve 44. Accordingly, the balls can be cammed outwardly by sloping surface 24 when inner member 12 is being removed, or by surface 32 when inner member 12 is being inserted into the outer telescoping member 10. Then, sleeve member 44 may be released, and so that spring 40 causes sleeve 44 to resume its initial positionr with balls 38 being cammed inwardly by annu-lar bevelled surface 46. If the inner member 12 is properly positioned within the ouker member 10, the balls will again reside in annular groove 20, to retain the two me~bers to-gether in sealed, locked configuration.
Retaining ring 48 serves to retain sleeve 46 on therest of outer telescoping member.
Because of the presence and arrangement of ribs 30, a preerred arrangement of which is shown, it is not possible for all of the balls 38 to fall inwardly to recessed area 28 if an attempt is made to lock the connector while the balls 38 overlie that area. Accordingly, it is not possible for sleeve 44 to be biased by spring 41, in that circumstance, into its closed position overlying balls 38. As a result, the possi-bility of a falsely locked indication is eliminated sincethe partially retracted sleeve 44, as shown in Figure 2, provides visual indication that the device is not locked.
Further retraction of sleeve 44 and an additional push of the ~3~

two connector members 10, 12 together will normally provide the desired complete, sealed lock as shown in Figures.land 3.
~igures 5 and 6 show the configuration of the device of this invention in its telescopLng but ~mlocked position in which ribs 30 prevent the sleeve 44 from assum-ing its locked position. As shown in the particular config-uration, several of the balls 38 are prevented by ribs 30 rom movîng inwardly, al.though some of the balls 38 can move in-wardly. This, however~ is sufficient to prevent the movementof sleeve 44 into its locked configuration overlying balls 38.
As a result o the above invention, it becomes possible to make use of inexpensive, molded plastic parts, and particularly a molded plastic inner telescoping member 12, which may be attached to disposable components of a medical device such as an artificial kidney or a component of a blood oxygenator system. For example~ connector.l~ may be attached to.the artificial kidney, an oxygenator, a cardioto~y reservoir, or the like, with a great reduction in connector expense, but no sacrifice in the reliability of operation of tha sealing-telescoping member of this invention~
The above has been offered for illustrative purposes only, and is not intended to limit the invention of this appli-cation, which is as defined in the claims below.
