## Abstract

Methods and systems for a catheter access port cleaning, disinfection or sterilization device are disclosed. The catheter access port cleaning, disinfection or sterilization device may comprise, a first housing having a power source and control circuit; a second housing shaped to mate with a catheter and having a first ultra-violet light source mounted therein, the first housing wired to the second housing to power the light source. When activated, the ultra-violet light source emits ultra-violet radiation that is transmitted from the second housing to the catheter attached to a patient. In this way, the device provides an efficient system for cleaning, disinfecting or sterilizing an access port in the second housing while reducing patient infections.

## Claims

### Claim 1

A system for cleaning, disinfection or sterilization of catheter access ports, comprising:
a plurality of cleaning, disinfection or sterilization devices, wherein each cleaning, disinfection or sterilization device of the plurality of cleaning, disinfection or sterilization devices comprises:
a first housing comprising a power source and control circuit; and
a second housing, wherein the first housing is substantially flat on both a top surface and a bottom surface as compared to a top surface and a bottom surface of the second housing;
wherein the second housing is shaped to mate with a catheter and having a first ultra-violet light source that is non-visible to a human eye mounted therein, the first housing wired to the second housing to power the first ultra-violet light source; wherein the first ultra-violet light source is configured to emit ultraviolet light of a predetermined wavelength of 100-280 nm that is directed to disinfect a catheter access port of the catheter for a duration of 1 second to 10 minutes; further wherein a visible light indicator is mounted to the catheter access port to indicate status of one of the plurality of cleaning, disinfection or sterilization devices that is coupled to the catheter access port by flashing a visible color when the ultraviolet light is emitted from the first ultra-violet light source; and
wherein each first housing of the plurality of cleaning, disinfection or sterilization devices is shaped identically, wherein the bottom surface of the first housing of each one of the of the plurality of cleaning, disinfection or sterilization devices is shaped to snap-fit with the top surface of the first housing of each one of the of the plurality of cleaning, disinfection or sterilization devices.

### Claim 2 (depends on 1)

The system of claim 1, wherein the top surface of the first housing includes one of a recess and a protrusion, and the bottom surface of the first housing includes the other of the recess and the protrusion.

### Claim 3 (depends on 2)

The system of claim 2, wherein the second housing has a luer lock.

### Claim 4 (depends on 3)

The system of claim 3, wherein the second housing wired to the first housing with wires and separate and freely-movable from the first housing.

### Claim 5 (depends on 4)

The system of claim 4, wherein the first housing includes a tab for attachment to the body or on a garments of a patient.

### Claim 6 (depends on 4)

The system of claim 4, wherein the first housing is disc-shaped.

### Claim 7 (depends on 1)

The system of claim 1, wherein the second housing includes a plurality of flat fins oppositely extending along an exterior surface of the second housing.

### Claim 8

A catheter cleaning kit having a plurality of housings, including a first housing having a power source and control circuit, a second housing shaped to mate with a catheter and having a first ultra-violet light source mounted therein, and a cable for connecting the first housing to the second housing; the catheter cleaning kit further comprising a handle having a separate power supply and a tamper-proof luer lock keyed to mate with the handle, the tamper-proof luer lock comprising a UV-C LED luer port shaped to connect to a luer of a catheter.

### Claim 9 (depends on 8)

The catheter cleaning kit of claim 8, wherein the cable is permanently affixed to one of the first and second housings.

### Claim 10 (depends on 8)

The catheter cleaning kit of claim 8, wherein the handle includes a visible indicator light source, and further comprises a male luer-lock fitting to mate with the tamper-proof luer lock.

### Claim 11 (depends on 10)

The catheter cleaning kit of claim 10, wherein the male luer-lock fitting mates with the tamper-proof luer lock at an opposite end from an opening having the UV-C LED luer port shaped to connect to the luer of the catheter.

### Claim 12 (depends on 10)

The catheter cleaning kit of claim 10, wherein the tamper-proof luer lock further comprises a retractable cover, thumb closure dial, and side-entrance with a silicone grip; wherein the retractable cover is comprised of a material that prevents accidental leakage of ultraviolet radiation from the catheter cleaning kit.

### Claim 13 (depends on 12)

The catheter cleaning kit of claim 12, wherein the material of the retractable cover is an opaque material.

### Claim 14 (depends on 10)

The catheter cleaning kit of claim 10, wherein the UV-C LED luer port is configured with an internal reflective surface to direct ultraviolet light to disinfect the UV-C LED luer port.
