Abstract
Abstract A needle connecting apparatus for connecting a needle to a syringe and for covering the needle for disposal includes a connector housing. A first mounting point on the connector housing mounts the housing to a syringe body. A second mounting point on the connector housing mounts base of a needle to the housing. A rigid needle cover is movably mounted to the connector housing for exposing a needle mounted to the connector housing when in a first position and for covering a needle mounted to the connector housing when in a second position.

Total Claims: 16
Claim 1
Independent Claim
112 words
A needle connecting apparatus for connecting a needle to a syringe and for covering the needle for disposal, the apparatus comprising: a connector housing including a barrel defining an enclosure; first mounting means on the connector housing for mounting the housing to a syringe body; second mounting means on the connector housing and within the enclosure for mounting a base of a needle to the housing; and a rigid needle cover movably mounted to and guided by the barrel of the connector housing for exposing a needle mounted to the connector housing when in a first position and for covering a needle mounted to the connector housing when in a second position.
Claim 2
Dependent Claim
112 words
A needle connecting apparatus for connecting a needle to a syringe and for covering the needle for disposal, the apparatus comprising: a connector housing including a barrel defining an enclosure; first mounting means on the connector housing for mounting the housing to a syringe body; second mounting means on the connector housing and within the enclosure for mounting a base of a needle to the housing; and a rigid needle cover movably mounted to and guided by the barrel of the connector housing for exposing a needle mounted to the connector housing when in a first position and for covering a needle mounted to the connector housing when in a second position.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 wherein the first mounting means includes a flange for engaging a syringe.
Claim 4
Dependent Claim
20 words
The apparatus of claim 1 wherein the second mounting means includes thread elements for engaging a base of a needle.
Claim 5
Dependent Claim
19 words
