Abstract

A method of maintaining sterility of fluidic medication in a fluidic medication container despite repeated extractions of the fluidic medication is provided. Also, a method of injecting a patient with fluidic medication without exposing the fluidic medication to ambient air is provided. The method may comprise the steps of providing a syringe with a sterilized variable fluid chamber with sterilized gas wherein the syringe is in a retracted position. A needle of the syringe is inserted into the fluidic medication container and the sterilized gas in the sterilized variable fluid chamber is transferred into the fluidic medication container to pressurize the same. Thereafter, fluidic medication is transferred from the fluidic medication container into the sterilized variable fluid chamber. The needle is removed from the fluidic medication container and inserted into the patient. The patient is injected with the fluidic medication in the sterilized variable fluid chamber.

Claims

1. A method of injecting a patient in a sterile manner, the method comprising the steps of:

a. providing a syringe in a retracted position with sterilized gas within a sterilized variable fluid chamber;

b. inserting a needle of the syringe in a sterile fluidic medication container;

c. traversing the syringe toward a filling position thereby transferring the sterilized gas of the variable fluid chamber into the sterile fluidic medication container and pressuring the sterile fluidic medication container;

d. traversing the syringe toward the retracted position thereby transferring fluidic medication contained within the sterile fluidic medication container into the sterilized variable fluid chamber;

e. removing the needle of the syringe from the sterile fluidic medication container; and

f. injecting the patient with the fluidic medication transferred into the sterilized variable fluid chamber.

2. The method of claim 1 wherein the inserting step is characterized by inserting the needle of the syringe through a self sealing rubber stopper of the sterile fluidic medication container.

3. The method of claim 1 further comprising the steps of:

a. disposing the retractable safety syringe in a package with the syringe in the retracted position; and

b. sterilizing an inner volume of the package.

4. The method of claim 1 wherein in the providing step, the retractable safety syringe is normally in the retracted position.

5. The method of claim 1 wherein the providing step further includes the step of providing a retractable safety syringe.

6. A method of maintaining sterility of a fluidic medication container despite repeated extractions of fluidic medication from the fluidic medication container, the method comprising the steps of:

a. providing a plurality of sterilized syringes in a retracted position with sterilized gas in a sterilized variable fluid chamber;

b. providing a sterile fluidic medication container wherein the container comprises a vial, fluidic medication contained within the vial, and a self sealing rubber stopper to contain the fluidic medication within the vial;

c. extracting fluidic medication from the vial via a first sterilized syringe, the extracting step comprising the steps of;

inserting a needle of the first sterilized syringe into the sterile fluidic medication container;

transferring the sterilized gas of the sterilized variable fluid chamber of the first sterilized syringe into the sterile fluidic medication container;

transferring the fluidic medication of the sterile fluidic medication container into the sterilized variable fluid chamber of the first sterilized syringe;

removing the needle of the first sterilized syringe from the sterile fluidic medication container;

d. extracting fluidic medication from the via a second sterilized syringe, the extracting step comprising the steps of;

inserting a needle of the second sterilized syringe into the sterile fluidic medication container;

transferring the sterilized gas of the sterilized variable fluid chamber of the second sterilized syringe into the sterile fluidic medication container;

transferring the fluidic medication of the sterile fluidic medication container into the sterilized variable fluid chamber of the second sterilized syringe;

removing the needle of the second sterilized syringe from the sterile fluidic medication container.

7. A device for maintaining sterility of a fluidic medication container and for injecting a patient with fluidic medication without exposing the fluidic medication to ambient air, the syringe comprising:

a syringe having a sterilized variable fluid chamber with sterile air contained in the sterilized variable fluid chamber; and

a hermetically sealed package sized and configured to receive the syringe, the package having a sterilized inner surface and sterile air contained in the package;

wherein the syringe is disposed within the hermetically sealed package with the syringe at a retracted position for providing sterilized air within the sterilized variable fluid chamber to be transferred into the sterile fluidic medication container.

8. The device of claim 7 wherein the syringe is a vacuum operated automatic retractable safety syringe.
