Abstract
In an embodiment, a syringe needle comprises a helical portion located in between a needle tip portion and a distal portion. In another embodiment, a compliant article 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 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.
Claims17
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.
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.
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.
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.
