Compliant syringe system, a method of making, and of using the same

1. A compliant article comprising:

a casing tube comprising a tube end opening located at a needle tube end of the casing tube, a distal tube opening located at a distal tube end of the casing tube, and an inner tube space; and

a syringe needle that traverses the tube end opening;

wherein the compliant article comprises a compliant portion that allows for a reduced insertion pressure of the syringe needle as compared to an insertion pressure of a corresponding syringe needle in an article without the compliant portion; and

wherein the compliant portion comprises a filled portion comprising a gel, a foam, or a combination comprising at least one of the foregoing.

2. The article of claim 1 , wherein the syringe needle is a straight syringe needle; and

wherein the filled portion is located in the casing tube at the casing tube end; and wherein the straight syringe needle traverses through the filled portion; or wherein the filled portion comprises a channel and the straight needle is located at a channel end located at the casing tube end; and/or

wherein the filled portion is located in a tube portion located at the distal tube end.

3. The article of claim 1 , wherein the filled portion has a modulus of 1 kilopascal to 10 megapascal.

4. The article of claim 1 , further comprising a stabilizer comprising a stabilizer opening, wherein one or both of the syringe needle and a needle hub are located on a distal end of the syringe needle that traverses the stabilizer opening.

5. The article of claim 1 , wherein the casing tube comprises a ridge at the distal tube end.

6. The article of claim 1 , further comprising:

a syringe located in the inner tube space of the casing tube; and

a plunger located in an inner syringe space of the syringe;

wherein the syringe comprises a syringe hub located at a hub barrel end of the syringe and a distal barrel opening located at a distal syringe end of the syringe; wherein the syringe hub is connected to the syringe needle.

7. The article of claim 6 , wherein the syringe needle comprises a needle hub, wherein the needle hub is threadably engaged with the syringe hub or wherein the needle hub and the syringe hub are locked together via a locking mechanism.

8. The article of claim 6 , wherein the syringe needle comprises a needle hub, and wherein the syringe hub is a slip tip located in the needle hub.

9. A compliant article comprising:

a casing tube comprising a tube end opening located at a needle tube end of the casing tube, a distal tube opening located at a distal tube end of the casing tube, and an inner tube space; and

a syringe needle that traverses the tube end opening;

wherein the compliant article comprises a compliant portion that allows for a reduced insertion pressure of the syringe needle as compared to an insertion pressure of a corresponding syringe needle in an article without the compliant portion;

wherein the compliant portion comprises a helical portion of the syringe needle; and wherein the syringe needle comprises the helical portion located in between a needle tip portion and a distal portion.

10. The syringe needle of claim 9 , further comprising a needle hub located on the distal portion.

11. The syringe needle of claim 9 , wherein the helical portion comprises 1 to 200 helical loops.

12. The syringe needle of claim 9 , wherein the needle tip portion has one or both of an outer diameter of 1.7 to 0.1 mm and an inner diameter of 1.3 to 0.005 mm.

13. A compliant article comprising:

a casing tube comprising a tube end opening located at a needle tube end of the casing tube, a distal tube opening located at a distal tube end of the casing tube, an inner tube space, a plunger located in the inner tube space, and a syringe needle that traverses the tube end opening;

wherein the compliant article comprises a compliant portion that allows for a reduced insertion pressure of the syringe needle as compared to an insertion pressure of a corresponding syringe needle in an article without the compliant portion.

14. The article of claim 13 , wherein the syringe needle is a straight syringe needle, and wherein the compliant portion comprises a spring located in the casing tube, helically surrounding the straight needle.

15. The article of claim 13 , wherein the compliant portion comprises a spring located in a spring tube portion located at the distal tube end of the casing tube.

16. A method of ejecting or taking in a fluid using a compliant syringe system comprising:

inserting a syringe needle into a patient; and

applying a pressure to the fluid and ejecting the fluid located in an inner tube space through the syringe needle; or withdrawing the fluid from the patient into the inner tube space through the syringe needle;

wherein the compliant syringe system comprises a casing tube comprising a tube end opening located at a needle tube end of the casing tube, a distal tube opening located at a distal tube end of the casing tube, and the inner tube space; wherein the syringe needle traverses the tube end opening; wherein the syringe needle is located on a syringe that comprises the inner syringe space, a syringe hub located at a hub barrel end of the syringe, and wherein the syringe is located in the inner tube space of the casing tube;

wherein the compliant syringe system comprises a compliant portion that allows for a reduced insertion pressure of the syringe needle as compared to an insertion pressure of a corresponding syringe needle in a syringe system without the compliant portion.

17. The method of claim 16 , further comprising determining a stiffness of the patient's epidermis and selecting a stiffness of the compliant syringe system that is less than or equal to the stiffness of the patient's epidermis prior to the inserting.
