Abstract

A device for holding a sealed container for a sterile hypodermic needle while the seal is broken, the needle is coupled to a syringe and removed by the syringe from the container and used one or more times on a single patient and then returned by the syringe to the container and the syringe is disconnected from the needle. The container is then released to fall into a disposal means. This eliminates contamination of the needle and infection of doctors and other authorized personnel by handling of the needle.

Claims

1. A disposal unit having an opening, a casing received in said opening containing a sterile needle sealed in the casing by a seal,

means for locking said casing in said opening while

a) the seal is opened to expose the needle,

b) a syringe is connected to the needle,

c) the needle is removed by the syringe from the casing and used by the syringe one or more times on a single patient,

d) the used needle is returned by the syringe to the casing,

e) the syringe is disconnected from the needle,

f) and then unlocking the casing and causing the casing and its needle to be delivered to disposal means.

2. The structure of claim 1 in which the disposal means is a removable disposal container.

3. The structure of claim 1 having a means for decreasing the size of said opening to grip the casing.

4. The structure of claim 1 in which the needle has a hub connected to the syringe.

5. The structure of claim 3 in which the opening is decreased in size by a lever movable toward one side of said opening.

6. The method of preventing infection by handling or using a sterile hypodermic needle individually packed in a sealed package which comprises locking the package in a convenient position and while the package is locked in position:

a) opening the package to provide access to the needle hub,

b) connecting a syringe to the needle hub,

c) removing the syringe from the package by the syringe and using the needle on a single patient one or more times,

d) returning the used needle to the package by the syringe,

e) disconnecting the syringe from the used needle, and then

f) unlocking the package and discharging the package and the needle contained therein to a disposal means.

7. The method of handling and disposing of an individual sterile needle packaged in a sealed container or casing which comprises:

a) locking the sealed container in a disposal structure,

b) opening the container to expose the needle hub,

c) connecting a syringe to the needle hub,

d) removing the needle by the syringe and using the needle one or more times on a single patient,

e) returning the used needle by the syringe to its container and

f) disconnecting the syringe from the needle hub, and then

g) unlocking the container and causing the container and the used needle to be delivered to disposal means.

8. The method of claim 7 in which the disposal means is a removable disposal container.
