## Abstract

The present invention is an enteral syringe for use with a support hook. The enteral syringe includes an elongated body having a hollow cavity therein and a plunger operable to selectively travel within the hollow cavity. The plunger includes a support feature adapted to receive the support hook.

## Claims

### Claim 1

An enteral syringe for use with a support hook, the syringe comprising:
an elongated body having a hollow cavity therein; and
a plunger operable to selectively travel within the hollow cavity, the plunger comprising a flange and a support feature adapted to receive the support hook, the support feature comprising a tether and an aperture between the flange and the tether for receiving the support hook to hang the syringe therefrom, the flange having a length and the tether being coupled to the flange and extending along a portion of the length of the flange.

### Claim 2 (depends on 1)

The enteral syringe of claim 1, wherein the tether is flexible.

### Claim 3 (depends on 1)

The enteral syringe of claim 1, wherein the support feature is adapted to support the enteral syringe at a variety of angles with respect to the support hook.

### Claim 4 (depends on 1)

The enteral syringe of claim 1, wherein the support feature is a rigid loop.

### Claim 5

A syringe for use with a support structure, the syringe comprising:
a barrel defining an interior chamber for receiving a fluid, and a discharge port for discharging the fluid therethrough; and
a plunger adapted to slide inwardly and outwardly within the barrel, the plunger having a flange with at least one notch formed in the flange; and
a tether attached to the flange of the plunger and extending across the notch of the plunger to define an aperture, adapted to receive the support structure for hanging the syringe.

### Claim 6 (depends on 5)

The syringe of claim 5, wherein the tether is flexible.

### Claim 7 (depends on 5)

The syringe of claim 5, wherein the tether is longer than the at least one plunger notch.

### Claim 8 (depends on 5)

The syringe of claim 5, wherein the tether is adapted to support the syringe at a variety of angles with respect to the support hook.

### Claim 9

A method of delivery of fluid from a syringe, the method comprising:
hanging the syringe from a support by engagement of the support within an aperture formed between a plunger flange portion of the syringe and a tether attached to the plunger flange portion of the syringe, and
delivering fluid from a discharge port of the syringe.

### Claim 10 (depends on 9)

The method of claim 9, wherein the tether is flexible.

### Claim 11 (depends on 9)

The method of claim 9, wherein the tether is adapted to support the syringe at a variety of angles with respect to the support.
