CLAIMS

1. A syringe adapter for withdrawing fluid medication from a container, comprising:

a support hub member radially surrounding at least a portion of a length of a sidewall, the sidewall extending between a proximal end and a distal end, the sidewall having an interior surface defining a chamber, the proximal end of the sidewall configured to be connected to a distal end of a syringe while withdrawing at least a portion of the fluid medication from the container through the chamber and into a barrel of the syringe and the distal end of the sidewall configured for inserting into the container for the withdrawal, wherein:

an opening at the distal end of the sidewall is relatively large in diameter to facilitate withdrawing fluid medication having a relatively high viscosity; and

a distal end of the support hub member is configured for removably receiving a proximal end of a needle holder, a distal end of the needle holder adapted for removably affixing thereto a needle with which at least a portion of the withdrawn fluid medication can be subsequently injected into a recipient.

2. The syringe adapter according to Claim 1 , wherein the relatively large opening improves syringeability of the fluid medication.

3. The syringe adapter according to Claim 1 , wherein the viscosity of the fluid medication is at least approximately 50 centipoise units when a temperature of the fluid medication is at least approximately 5 degrees Celsius.

4. The syringe adapter according to Claim 1 , wherein the syringe is configured as a pistol-grip syringe.

5. The syringe adapter according to Claim 4, wherein the pistol-grip syringe improves leverage for the subsequent injection.

6. The syringe adapter according to Claim 1 , wherein the syringe is configured as a tab-handled syringe.

7. The syringe adapter according to Claim 1 , wherein the diameter of the opening at the distal end of the sidewall is approximately 0.10 inches.

8. The syringe adapter according to Claim 1 , wherein the syringe adapter connects to the syringe using a Luer-type lock to connect an internal threaded portion of the distal end of the syringe and a flanged area at the proximal end of the sidewall.

9. The syringe adapter according to Claim 1 , wherein a distal end of the support hub member provides for a Luer-type lock connection with the needle holder, the distal end of the support hub member having an internal threaded portion for receiving a flanged area at the proximal end of the needle holder.

10. The syringe adapter according to Claim 1 , wherein the sidewall is approximately 0.05 inches in thickness at the distal end.

11. The syringe adapter according to Claim 1 , further comprising a flanged area that extends perpendicularly from the proximal end of the sidewall.

12. The syringe adapter according to Claim 1 , further comprising a radial extension member that extends perpendicularly and radially outward from an exterior surface of the needle holder.

13. The syringe adapter according to Claim 1 , wherein a shape of the chamber is generally conical

14. The syringe adapter according to Claim 1 , wherein a shape of the chamber tapers from the proximal end of the sidewall toward the distal end of the sidewall, for at least a portion of the proximal end, at approximately 6 percent.

15. A method of administering fluid medication, comprising:

affixing a syringe adapter to a syringe, the syringe adapter comprising a sidewall extending between a proximal end and a distal end and a support hub member radially surrounding at least a portion of a length of the sidewall, the sidewall having an interior surface defining a chamber, the proximal end of the sidewall configured to be connected to a distal end of the syringe;

inserting the distal end of the of the sidewall into a container of fluid medication having a relatively high viscosity;

withdrawing, from the container, at least a portion of the fluid medication through the chamber and into a barrel of the syringe, wherein an opening at the distal end of the sidewall is relatively large in diameter to facilitate withdrawing the relatively-high-viscosity medication;

subsequent to the withdrawing from the container, affixing a proximal

end of a needle holder to a distal end of the support hub member, a distal end of the needle holder having affixed thereto a proximal end of a needle; and

injecting, into a recipient with the needle, at least a portion of the fluid medication withdrawn into the barrel.

16. A system for administering higher-viscosity fluid medication, comprising:

a syringe;

a syringe adapter comprising a sidewall extending between a proximal end and a distal end and a support hub member radially surrounding at least a portion of a length of the sidewall, the sidewall having an interior surface defining a chamber, the proximal end of the sidewall configured to be connected to the syringe while withdrawing at least a portion of the fluid medication from a container through the chamber and into a barrel of the syringe and the distal end of the sidewall configured for inserting info the container for the withdrawal, wherein an opening at the distal end of the sidewall is relatively large in diameter to facilitate withdrawing the

higher-viscosity fluid medication from the container; and

a needle holder adapted for removably affixing thereto a needle, the needle holder configured for connecting to the support hub member subsequent to the withdrawing of the fluid medication and while the syringe adapter remains connected to the syringe, the needle further configured for injecting, into a recipient, at least a portion of the fluid medication withdrawn into the barrel.

17. A method, comprising:

inserting a distal end of a syringe adapter into a container of fluid medication having a relatively high viscosity, a proximal end of the syringe adapter being affixed to a distal end of a syringe, the syringe adapter comprising a support hub member radially surrounding at least a portion of a length of a sidewall, the sidewall extending between a proximal end and a distal end and having an interior surface defining a chamber; and

withdrawing, from the container, at least a portion of the fluid medication through the chamber and into a barrel of the syringe, wherein an opening at the distal end of the sidewall is relatively large in diameter to facilitate withdrawing the

relative!y-high-viseosity medication, wherein:

the support hub member is configured to removably receive, at a distal end thereof, a proximal end of a needle holder , subsequent to the withdrawing from the container, the needle holder adapted for removably affixing a needle to a distal end thereof; and

the needle holder is configured to remain attached to the support hub member while the needle is used for injecting, into a recipient with the needle affixed to the needle holder, at least a portion of the fluid medication withdrawn into the barrel.

18. The method according to Claim 17, wherein the proximal end of the syringe adapter is permanently affixed to the distal end of the syringe.

19 The method according to Claim 18, wherein the proximal end of the syringe adapter is permanently affixed to the distal end of the syringe by inserting, into a cavity at the distal end of the syringe, an extension from the proximal end of the syringe adapter.
