Abstract
Abstract Disclosed is a connector for introducing medication into a patient in a safe, convenient way. It comprises a pair of plastic tubular members adapted to be manually pushed together to engage in a male-female relationship, and a locking mechanism that detachably secures the members together. The male member has a sealed entry port at its end, and the female member safely houses within it a needle which centrally pierces the seal of the port upon engagement of the members. Preferably, the locking mechanism provides a "click" sound when it locks the members together.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
211 words
A safety connector system which permits the repeated connection and disconnection of an end of a first conduit to an end of a second conduit for permitting the flow of fluid between said first and second conduits in a medical environment, said end of said first conduit being sealed by a nonremovable septum, comprising: a hollow tube connected to said end of said second conduit, said tube having a diameter which is small enough in comparison with the diameter of said septum that said septum is capable of repeatedly resealing said end of said first conduit through resilient closure after said tube has penetrated said septum and been removed therefrom, said tube having sufficient rigidity to penetrate said septum when said end of said first conduit is advanced toward said end of said second conduit; a first latching member on said end of said first conduit; and a second latching member on said end of said second conduit, said first and second latching members cooperating to hold said tube in a position penetrating said septum, thereby preventing unintentional disconnection of said ends of said first and second conduits and preventing the disruption of fluid traveling between said first and second conduits when said first conduit is engaged with said second conduit.

A safety connector system which permits the repeated connection and disconnection of an end of a first conduit to an end of a second conduit for permitting the flow of fluid between said first and second conduits in a medical environment, said end of said first conduit being sealed by a nonremovable septum, comprising: a hollow tube connected to said end of said second conduit, said tube having a diameter which is small enough in comparison with the diameter of said septum that said septum is capable of repeatedly resealing said end of said first conduit through resilient closure after said tube has penetrated said septum and been removed therefrom, said tube having sufficient rigidity to penetrate said septum when said end of said first conduit is advanced toward said end of said second conduit; a first latching member on said end of said first conduit; and a second latching member on said end of said second conduit, said first and second latching members cooperating to hold said tube in a position penetrating said septum, thereby preventing unintentional disconnection of said ends of said first and second conduits and preventing the disruption of fluid traveling between said first and second conduits when said first conduit is engaged with said second conduit.
Claim 3
Dependent Claim
21 words

Claim 6
Dependent Claim
28 words
The connector system of claim 1, wherein said first latching member comprises a lip and said second latching member comprises a lever arm which slides over said lip.
Claim 7
Dependent Claim
36 words
The connector system of claim 1, wherein said first latching member comprises at least one pin mounted on said first conduit and said second latching member comprises at least one J-type slot for receiving said pin.
Claim 8
Dependent Claim
21 words
The connector system of claim 1, wherein said hollow tube is disposed within a housing which substantially surrounds said hollow tube.
Claim 9
Dependent Claim
13 words

Claim 10
Dependent Claim
129 words
A safety connector system for transferring medication from a first conduit to a second conduit in a medical environment comprising: a resealable, resilient septum located at an end of said first conduit, said end of said first conduit having a first locking mechanism thereon; a piercing element at an end of said second conduit, said second conduit having a second locking mechanism thereon for detachably engaging with said first locking element, wherein said piercing element penetrates said septum when said first and second locking mechanisms are engaged and further, wherein said seal reseals when said first and second locking mechanisms are disengaged and said piercing element is withdrawn from said septum, said seal being capable of repeatedly accepting said piercing element and resealing after withdrawal of said piercing element.
Claim 11
Dependent Claim
129 words
A safety connector system for transferring medication from a first conduit to a second conduit in a medical environment comprising: a resealable, resilient septum located at an end of said first conduit, said end of said first conduit having a first locking mechanism thereon; a piercing element at an end of said second conduit, said second conduit having a second locking mechanism thereon for detachably engaging with said first locking element, wherein said piercing element penetrates said septum when said first and second locking mechanisms are engaged and further, wherein said seal reseals when said first and second locking mechanisms are disengaged and said piercing element is withdrawn from said septum, said seal being capable of repeatedly accepting said piercing element and resealing after withdrawal of said piercing element.
Claim 12
Dependent Claim
17 words
