Claim 5

A protected needle coupling according to claim 1 further comprising tab means extending outward from said telescoping means for manually forcing said telescoping means into said housing.

Claim 6

A protected needle coupling according to claim 1 wherein said telescoping means comprises a tubular sleeve and said finger means are formed by slits along said tubular sleeve.

Claim 7

A protected needle coupling according to claim 5 wherein one of said slits is wide enough to enable an injection port to extend laterally therein.

Claim 8

A protected needle coupling according to claim 4 wherein said finger means are substantially semi-cylindrical in configuration and have an opening at one side thereof for receiving said IV injection port, and shoulder means for engagement with an annular shoulder of said injection port.

Claim 9

A protected needle coupling according to claim 7 further comprising tab means extending outward from said telescoping means for manually forcing said telescoping means into said housing.

Claim 10

A protected needle coupling according to claim 8 further comprising latching means for releasably latching said telescoping means in said housing.

Claim 11

A detachable protected needle coupling for one hand detachable connection to an IV injection site comprising: an elongated tubular housing having a proximal end and a distal end; needle mounting means at said proximal end for mounting a conventional needle in a protected coaxial position within said housing for extending toward said distal end; connecting means at said proximal end for connection to an IV source; and telescoping tubular means mounted in said housing an having axially extending slits defining opposed finger means extendable from said distal end of said housing for engaging an IV injection port for pulling said injection port into said housing upon movement of said tubular means into said housing for coupling engagement with said needle therein.

Claim 12

A detachable protected needle coupling for one hand detachable connection to an IV injection site comprising: an elongated tubular housing having a proximal end and a distal end; needle mounting means at said proximal end for mounting a conventional needle in a protected coaxial position within said housing for extending toward said distal end; connecting means at said proximal end for connection to an IV source; and telescoping tubular means mounted in said housing an having axially extending slits defining opposed finger means extendable from said distal end of said housing for engaging an IV injection port for pulling said injection port into said housing upon movement of said tubular means into said housing for coupling engagement with said needle therein.

Claim 13

A protected needle coupling according to claim 10 wherein said finger means have inwardly directed shoulder means at outer ends thereof for engaging a shoulder of an IV injection port.

Claim 14

A protected needle coupling according to claim 11 further comprising tab means extending outward from said telescoping means for manually forcing said telescoping means into said housing.

Claim 15

A protected needle coupling according to claim 12 further comprising latching means for releasably latching said telescoping means in said housing.

Claim 16

A protected needle coupling according to claim 13 wherein one of said slits is wide enough to enable an injection port to extend laterally therein.

Claim 17

A detachable protected needle coupling for one hand detachable connection to an IV injection port of IV infusion system comprising in combination: an elongated tubular housing having a proximal end and a distal end; a needle mounted at said proximal end and extending coaxial thereof toward said distal end with a tip disposed in a protected position within said housing; connecting means at said proximal end for connecting to an IV source telescoping tubular means reciprocally mounted in said housing for movement between innermost and outermost positions within said housing and having axially extending slits defining a pair of opposed semi-cylindrical fingers extendable from said distal end of said housing and having inwardly directed shoulder means at outer ends thereof for engaging a shoulder of an IV injection port for pulling said injection port into said housing upon movement of said tubular means away from said distal end to said innermost position for coupling engagement with said needle therein; tab means extending outward from said telescoping means for manually forcing said telescoping means between said innermost position and said outermost position in said housing; and latching means for releasably latching said telescoping means in an innermost position in said housing.

Claim 18

A detachable protected needle coupling for one hand detachable connection to an IV injection port of IV infusion system comprising in combination: an elongated tubular housing having a proximal end and a distal end; a needle mounted at said proximal end and extending coaxial thereof toward said distal end with a tip disposed in a protected position within said housing; connecting means at said proximal end for connecting to an IV source telescoping tubular means reciprocally mounted in said housing for movement between innermost and outermost positions within said housing and having axially extending slits defining a pair of opposed semi-cylindrical fingers extendable from said distal end of said housing and having inwardly directed shoulder means at outer ends thereof for engaging a shoulder of an IV injection port for pulling said injection port into said housing upon movement of said tubular means away from said distal end to said innermost position for coupling engagement with said needle therein; tab means extending outward from said telescoping means for manually forcing said telescoping means between said innermost position and said outermost position in said housing; and latching means for releasably latching said telescoping means in an innermost position in said housing.

Claim 19

A protected needle coupling according to claim 15 wherein one of said slits is of sufficient width to enable an injection port to extend laterally therethrough for positioning between said fingers.
