Abstract

A dispensing device formed of a cradle for receiving a brick pack. The cradle includes a pair of apertures located near the bottom and top of the cradle. The dispensing member has a pair of spikes at each end thereof which pass through the pair of apertures in the cradle and pierce the brick pack contained by the cradle. The spikes each have openings therein which communicate with the hollow interior of the dispenser to permit the flow of fluid therein. At the top end of the dispenser is a vent opening having a filter therein for permitting the ingress of air. At the bottom of the dispenser is an opening for permitting the egress of fluid from the brick pack and the dispenser. Preferably the dispenser has a graduated scale to indicate the level of fluid in the brick pack.

Claims

1. A dispensing device for enteral or intravenous injection of fluids into a patient comprising:

a cradle member for supporting a disposable aseptic rectangular package of fluid at a tilted angle so that said package has a single uppermost and lowermost location, said cradle member including a pair of side walls diagonally disposed between diagonal corners of sides on said dispensing package, said cradle side walls having uppermost and lowermost corners, said side walls being terminated in a lowermost cross member and in an uppermost cross member for interconnecting said side walls, said cross members each having horizontal and vertical portions interconnecting said side walls, said side walls and said cross members defining a truncated rectangular shaped box, a first hole formed in at least one side wall proximate said uppermost corner and a second hole formed in at least one side wall proximate said lowermost corner and a hangle fixedly secured to said upper cross member for supporting said cradle member; and

a dispensing means for dispensing said fluid from said aseptic package, said dispensing means including means for piercing said package through said holes in said side walls to draw fluid therefrom into said dispensing means, said dispensing means further comprising an opening at the top thereof, said opening comprising an air filter for removing particulate matter from the air entering said dispensing means, and

means for indicating the level of fluid in said package.

2. The dispensing device of claim 1 wherein said dispensing means includes a hollow interior portion for receiving fluid from said package, said fluid rising in said hollow interior to the level of said fluid in said package;

and said means for indicating comprises

a graduated scale.

3. The dispensing device of claim 1 wherein said cradle member further comprises means for maintaining said cradle and said dispensing means in a vertical orientation.

4. A dispensing device of claim 3 wherein said maintaining means comprises a reduced cross section portion between said handle and said cradle member for maintaining said cradle and said dispensing means in a vertical orientation.

5. The dispensing device of claim 1 wherein said means for piercing comprises a pair of spikes, one each positioned approximate the top and bottom of the dispensing member, said spikes having a channel therethrough for permitting the egress of fluid from said package through said channel into said dispensing means and for permitting the egress of air from the dispensing means into said package.

6. The dispensing device of claim 5 wherein said channels through said spikes are at an oblique angle with respect to the longitudinal axis of said spikes so that particles from said package do not clog said channels into said dispensing means.

7. The dispensing device of claim 6 wherein said means for indicating comprises a scale on said dispensing means and a scale marker selectively positionable along the scale of said dispensing means for indicating when a predetermined amount of fluid has been dispensed.

8. A dispensing device for enteral or intravenous injection of fluids into a patient comprising:

a cradle member for supporting a disposable rectangular package of aseptic fluid at a tilted angle so that said fluid has a single uppermost and a single lowermost location, said cradle having a pair of side walls diagonally disposed between diagonal corners of sides on said package and terminated in an uppermost and an lowermost cross member, each cross member having a generally vertically portion and a generally horizontally portion, said side walls and cross members defining a support for receiving an retaining said package of fluid, a first hole being formed in at least one side wall proximate said uppermost cross member a second hole being formed in at least one side wall proximate said lowermost cross member, and a handle fixedly secured to said upper cross member for supporting said cradle member;

a dispensing means for dispensing said aseptic fluid from said package, said dispensing means including means for piercing said package at said uppermost and said lowermost locations to draw fluid therefrom into said dispensing means, said piercing means comprising a pair of spikes, one each positioned proximate the top and bottom of said dispensing member, said spikes having a channel therethrough for permitting the egress of fluid from said package through said channel into the bottom of said dispensing means and for permitting the ingress of air from the top said dispensing means into said package,

means for conveying said fluid from said bottom of said dispensing means to a patient, and

means for indicating the level of fluid in said package.

9. A dispensing device of claim 8 wherein said dispensing member includes a hollow interior portion for receiving fluid from said package, said fluid rising in said hollow interior to the level of said fluid in said package, and said means for indicating comprises a graduated scale;

and

an opening in the top of said dispensing member, said opening comprising an air filter for removing particulate matter from the air entering the dispensing member.

10. A dispensing device of claim 9 wherein said handle includes a reduced cross-section portion for maintaining said package tilted with said first and second holes in said side walls proximate the uppermost and lowermost locations respectively.

11. A dispensing device according to claim 9 wherein said side walls of said cradle member are integrally formed with said uppermost crossmember.
