Antiseptic cap that releases a gas such as nitric oxide
A syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.
1. An antiseptic medical cap comprising:
a base comprising a proximal surface and a distal surface;
a sidewall extending distally from the base, the sidewall comprising a proximal end and a distal end;
an interior surface extending around an interior of the sidewall and the distal surface of the base, the interior surface forming a chamber that is sized and shaped so as to be capable of receiving and surrounding a proximal end of a medical fluid port with an opening; and
an insert extending distally from the distal surface of the base beyond the distal end of the sidewall, the insert being sized and shaped to be positionable within the opening of the fluid port when the proximal end of the fluid port is received into the chamber of the antiseptic cap;
wherein the insert includes a gas-releasing anti-microbial compound.
2. A combination of the antiseptic medical cap of claim 1 and the medical fluid port.
3. The combination of claim 2 , wherein the medical fluid port is an access site with a valve.
4. The combination of claim 3 , wherein the insert is a post configured to open the valve of the access site when the medical fluid port is received within the chamber of the antiseptic cap.
5. The antiseptic medical cap of claim 1 , wherein the interior surface of the antiseptic medical cap comprises threads configured to mate with corresponding threads on the fluid port.
6. An antiseptic medical cap comprising:
a proximal base comprising a proximal surface and a distal surface;
a sidewall extending distally from the proximal base, the sidewall comprising a proximal end and a distal end;
a chamber formed by an inner surface extending around the proximal base and the sidewall, the chamber being sized and shaped so as to be capable of receiving a proximal end of a fluid port with an opening; and
a nitric oxide-releasing system extending distally from the distal surface of the proximal base beyond the distal end of the sidewall, the nitric oxide-releasing system being sized and shaped to be positionable within the opening of the fluid port when the proximal end of the fluid port is received into the chamber of the antiseptic cap.
7. A combination of the antiseptic cap of claim 6 and the fluid port.
8. The combination of claim 7 , wherein the fluid port is an access site with a valve.
9. The combination of claim 8 , wherein the nitric oxide-releasing system is a coating on a post.
10. The combination of claim 9 , wherein the post is configured to open the valve of the access site when the fluid port is received within the chamber of the antiseptic cap.
11. The antiseptic cap of claim 6 , wherein the inner surface of the antiseptic cap comprises threads configured to mate with corresponding threads on the fluid port.
12. The antiseptic cap of claim 6 , wherein the nitric oxide-releasing system includes a compound comprising zinc.
13. An antiseptic medical cap comprising:
a base comprising a proximal surface and a distal surface;
a sidewall extending distally from the base, the sidewall comprising a proximal end and a distal end;
an interior surface extending around an interior of the sidewall and the distal surface of the base, the interior surface forming a chamber that is sized and shaped so as to be capable of receiving and surrounding a proximal end of a medical fluid port with an opening; and
an insert extending distally from the distal surface of the base beyond the distal end of the sidewall, the insert being sized and shaped to be positionable within the opening of the fluid port when the proximal end of the fluid port is received into the chamber of the antiseptic cap;
wherein the insert includes a nitric oxide-releasing system and a compound comprising zinc.
14. A method of using an antiseptic medical cap comprising:
obtaining an antiseptic medical cap comprising:
a proximal base with proximal and distal surfaces;
a sidewall extending distally from the proximal base, the sidewall comprising a proximal end and a distal end;
an interior chamber; and
a gas-releasing system extending distally from the distal surface of the proximal base beyond the distal end of the sidewall; and
attaching the antiseptic medical cap to a medical fluid port with a proximal opening such that the gas-releasing system is positioned within the opening of the fluid port.
