Abstract
Abstract A valved connector arrangement having a pair of tubes and a slitted transverse elastic disk partition normally separating and disconnecting the interior of the two tubes, one of the two tubes being slidable toward and away from the slitted disk partition to effect mechanical opening and permit self-reclosing of the slitted partition. In the embodiment, the other tube is fixed, and the two tubes are pointed at their outer ends to enable their use in a multiple sample blood collecting needle arrangement, including a removable vacuum collecting container with a rubber stopper engageable by one of the pointed tubes.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
192 words
A valved needle arrangement comprising: a housing having a cavity formed therein, first and second cannulas connecting with said housing and each having an open end thereof connecting in fluid flow relation with a portion of said cavity, an elastic partition in said housing cavity and normally separating said cannulas in fluid flow disconnection from one another, said partition having a pre-formed self-closing transverse slit therein and extending therethrough and with interfacing normally contiguous lips for passage accommodation therethrough of one of said cannulas to enable fluid flow communication between said cannulas, one of said cannula being longitudinally slidable toward and away from said partition and being generally longitudinally aligned with said pre-formed slit, said one slidable cannula having a blunt end movable within said cavity and selectively engageable with said partition in the zone of said slit to laterally separate and open the normally closed lips of said slit in said partition as a function of longitudinal sliding movement of said one cannula toward and into lip-parting engagement with said partition; the lips of said partition slit being elastically self-closing upon longitudinal movement of said one cannula away from said partition.
Claim 2
Dependent Claim
192 words
A valved needle arrangement comprising: a housing having a cavity formed therein, first and second cannulas connecting with said housing and each having an open end thereof connecting in fluid flow relation with a portion of said cavity, an elastic partition in said housing cavity and normally separating said cannulas in fluid flow disconnection from one another, said partition having a pre-formed self-closing transverse slit therein and extending therethrough and with interfacing normally contiguous lips for passage accommodation therethrough of one of said cannulas to enable fluid flow communication between said cannulas, one of said cannula being longitudinally slidable toward and away from said partition and being generally longitudinally aligned with said pre-formed slit, said one slidable cannula having a blunt end movable within said cavity and selectively engageable with said partition in the zone of said slit to laterally separate and open the normally closed lips of said slit in said partition as a function of longitudinal sliding movement of said one cannula toward and into lip-parting engagement with said partition; the lips of said partition slit being elastically self-closing upon longitudinal movement of said one cannula away from said partition.
Claim 3
Dependent Claim
15 words
Apparatus according to claim 1, second said cannula being in fixed relation with said housing.
Claim 4
Dependent Claim
21 words
Apparatus according to claim 1, at least one of said two cannulas having a pointed puncture-effecting end at its outer end.
Claim 5
Dependent Claim
15 words
Apparatus according to claim 3, both of said two cannulas having pointed puncture-effecting outer ends.
Claim 6
Dependent Claim
16 words
Apparatus according to claim 4, said second cannula being secured in fixed relation in said housing.
Claim 7
Dependent Claim
29 words
Apparatus according to claim 1, said one slidable cannula having a transversely extending stop formed thereon and disposed within said cavity to limit longitudinal movement of said one cannula.
Claim 8
Dependent Claim
19 words
Apparatus according to claim 6, said stop comprising an enlargement of the blunt inner end of said one cannula.
Claim 9
Dependent Claim
16 words
Apparatus according to claim 7, said cannula enlargement comprising a flared end of said one cannula.
Claim 10
Dependent Claim
23 words
Apparatus according to claim 1, said slit being linear and forming a cat-eye shape upon lip-separation by passage of said one cannula therethrough.
Claim 11
Dependent Claim
21 words
Apparatus according to claim 9, said cat-eye shape slit opening forming lateral apertures on opposite lateral sides of said one cannula.
Claim 12
Dependent Claim
39 words
Apparatus according to claim 10, said housing having a bushing portion forming a close interference fit sleeve seal about said one cannula for sealed sliding friction fit therebetween, and said housing being effectively unitary with the other said cannula.
Claim 13
Dependent Claim
44 words
Apparatus according to claim 10, further comprising a vacuum-operating liquid collecting container engageable in fluid-flow relation with said one slidable cannula, said one slidable cannula being slidable toward and away from said partition as a function of connection and disconnection thereof with said container.
Claim 14
Dependent Claim
18 words
Apparatus according to claim 1, said pre-formed slit having a straight line configuratiOn with parallel interfacing contiguous lips.
