## Abstract

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.

## Claims

### Claim 1

(canceled)

### Claim 2

A method of providing an antiseptic medical cap, the method comprising:
providing a base comprising a proximal surface and a distal surface;
providing a sidewall extending distally from the base, the sidewall comprising a proximal end and a distal end;
providing 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
providing 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.

### Claim 3 (depends on 2)

The method of claim 2, wherein the gas-releasing anti-microbial compound is configured to release nitric oxide.

### Claim 4 (depends on 2)

The method of claim 2, wherein providing the insert comprises coating the gas-releasing anti-microbial compound on the insert.

### Claim 5 (depends on 2)

The method of claim 2, wherein the insert further comprises zinc.

### Claim 6 (depends on 2)

The method of claim 2, wherein providing the interior surface of the sidewall comprises providing threads configured to mate with corresponding threads on the medical fluid port.

### Claim 7 (depends on 2)

The method of claim 2, wherein the chamber is at least partially defined by an inner surface extending along the distal surface of the base and the sidewall.

### Claim 8 (depends on 2)

The method of claim 2, further comprising providing the medical fluid port.

### Claim 9 (depends on 8)

The method of claim 8, wherein the medical fluid port is an access site with a valve.

### Claim 10 (depends on 9)

The method of claim 9, 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 medical cap.
