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.
Claims22
A safety connector system for administering a first and a second fluid to a patient, comprising:
- a generally Y-shaped piggyback connector having a first influent fluid line on a first influent side thereof for administration of said first fluid and a pierceable septum on a branch port on a second influent side thereof for administration of said second fluid, said Y-shaped piggyback connector having a first locking element thereon and also having an effluent fluid line on an effluent side thereof;
- and
- a safety connected for securing a second influent fluid line to said branch port, said safety connector having a generally tubular body with a piercing element disposed therein, said tubular body adapted to advance over said pierceable septum and thereby cause said piercing element to engage said pierceable septum on said branch port, said safety connector further comprising a second locking element for detachably engaging said first locking element, thereby locking said piercing element and said pierceable septum in fluid communication.
A safety connector system for infusing a first fluid and a second fluid into a patient, comprising:
- a piggyback connector of the type having a first locking element, a first fluid input cavity, an input side port having a pierceable seal thereon for receiving said second fluid, and an effluent cavity;
- and
- a safety connector comprising a generally tubular guard member housing a piercing element disposed therein adapted to pierce said pierceable seal on said input side port, said guard member adapted to be advanceable over said pierceable seal such that said piercing element penetrates said pierceable seal to allow a source of fluid to flow through said safety connector and into said piggyback connector, said safety connector further comprising a second locking element thereon for engaging said first locking element and locking said safety connector to said piggyback connector.
A safety connector system for administering medication intravenously to a patient, comprising:
- a port element having first, second and third ends, said first end of said port element having a pierceable seal thereon, said second end of said port element being in fluid communication with a first source of fluid and said third end of said port element for fluid communication with a patient, said port element having a first locking element thereon;
- and
- a cap member having a cavity therein, said cavity containing a piercing element adapted to engage said pierceable seal of said first end of said port element when said first end of said port element is inserted into said cap member, said cap member further comprising a second locking element for removably engaging said cap member and said port element such that said first end of said port element may be secured within said cavity of said cap member when said second locking element and said first locking element are engaged.
A safety connector system for providing medication from two remote sources through tubing to a patient, comprising:
- a Y-shaped piggyback connector having a first, second and third end and a first locking structure, said first end being a port with a pierceable seal thereon for engagement with a safety connector that is connected to a first source of fluid, said second end being in fluid communication with a second source of fluid, and said third end for fluid communication with a patient, said pierceable seal designed to be penetrated by a piercing element on said safety connector;
- and
- a safety connector having a housing with a piercing element disposed therein, said piercing element being in fluid communication with said first source of fluid, said housing adapted to detachably engage said port such that said piercing element penetrates said pierceable seal when said port and said housing are engaged, said piercing element being disposed within a cavity of said housing and said cavity having an open mouth for receiving said port, said housing further comprising a second locking element to detachably secure said second locking element to said first locking element.
