## Abstract

Described herein are devices for delivering at least two different medications without requiring disconnections and reconnections of medication syringes. In some embodiments, the devices can accommodate at least two syringes simultaneously. In some embodiments, the device can be torqued while delivering the at least two different medications without loosening the outlet port from an intravenous line the device is hooked up to.

## Claims

### Claim 1

A device for delivering at least two different medications, the device comprising:
a body section including:
a first inlet port including an anti-reflux valve and operably connected to a first smaller pore filter;
a second inlet port including an anti-reflux valve and operably connected to a second larger pore filter;
at least one additional inlet port connected to the first filter; and
a rotating outlet port including a collar which surrounds the outlet port,
wherein the collar includes a ratcheting mechanism having
a gear including teeth and spaces between the teeth, wherein the gear runs around an internal circumference of the collar, and
a delivery protrusion with pawls being lock into the spaces between the teeth, and wherein the pawls are only rotatable within the spaces between teeth;
wherein the rotating outlet port is joined to the first filter and the second filter by a y-connector;
wherein the rotating outlet port is configured to connect to an intravenous line such that the intravenous line is only allowed to disengage from the rotating outlet port by holding the collar when disconnecting the intravenous line; and
wherein the device can be torqued while delivering the at least two different medications without loosening the rotating outlet port from the intravenous line.

### Claim 2 (depends on 1)

The device of claim 1, wherein the first filter is a 0.2 μm filter.

### Claim 3 (depends on 2)

The device of claim 2, wherein six inlet ports flow into the first filter.

### Claim 4 (depends on 1)

The device of claim 1, wherein the second filter is a 5 μm filter.

### Claim 5 (depends on 2)

The device of claim 2, wherein two inlet ports flow into the second filter.

### Claim 6 (depends on 1)

The device of claim 1 including two inlet ports.

### Claim 7 (depends on 1)

The device of claim 1, wherein the at least two inlet ports are scrubbable inlet ports.

### Claim 8 (depends on 1)

The device of claim 1 including a minimal amount of dead space.

### Claim 9 (depends on 1)

The device of claim 1, wherein the rotating outlet port is a male luer.
