## 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 method of delivering at least two different time sensitive medications, the method comprising:
delivering at least a first medication in a first syringe and a second medication in a second syringe through a device into an intravenous line without disconnecting the first syringe or the second syringe.

### Claim 2 (depends on 1)

The method of claim 1, wherein the first medication is an anesthetic.

### Claim 3 (depends on 2)

The method of claim 2, wherein the anesthetic is propofol.

### Claim 4 (depends on 1)

The method of claim 1, wherein the device includes a body section including at least two inlet ports;
wherein at least one of the at least two inlet ports includes an anti-reflux valve and is operably connected to a first filter; and
wherein at least another inlet port of the at least two inlet ports includes an anti-reflux valve and is operably connected to a second filter.

### Claim 5 (depends on 4)

The method of claim 4, wherein the device includes a rotating outlet port joined to the first filter and the second filter by a y-connector and configured to connect to the intravenous line.

### Claim 6 (depends on 1)

The method of claim 1, further comprising delivering at least a third medication in a third syringe through the device into the intravenous line without disconnecting the first syringe, the second syringe, or the third syringe.

### Claim 7 (depends on 6)

The method of claim 6, further comprising delivering at least a fourth medication in a fourth syringe through the device into the intravenous line without disconnecting the first syringe, the second syringe, the third syringe, or the fourth syringe.

### Claim 8 (depends on 7)

The method of claim 7, further comprising delivering at least a fifth medication in a fifth syringe through the device into the intravenous line without disconnecting the first syringe, the second syringe, the third syringe, the fourth syringe, or the fifth syringe.

### Claim 9 (depends on 1)

The method of claim 1, further comprising delivering at least a third medication in a third syringe, a fourth medication in a fourth syringe, a fifth medication in a fifth syringe, a sixth medication in a sixth syringe, a seventh medication in a seventh syringe, and an eighth medication in an eighth syringe through the device into the intravenous line without disconnecting the first syringe, the second syringe, the third syringe, the fourth syringe, the fifth syringe, the sixth syringe, the seventh syringe, or the eighth syringe.

### Claim 10 (depends on 1)

The method of claim 1, wherein the delivering reduces a patient's chance of infection, reduces the chance of particle infusion, reduces the chance of air infusion, or a combination thereof.
