Pressure infusion device and process for making a pressure infusion device
View Patent ↗A pressure infusion device including a sealed bag of flexible, heat sealable material including generally opposed edge portions; a layer of substantially transparent material including generally oppose edge portions provided with a plurality of holes; the opposed edge portions of the sealed bag are folded over the opposed edge portions of the layer of substantially transparent material and are heat sealed to the sealed bag through the holes. A process for making a pressure infusion device including the steps of providing a sealed bag of flexible, heat-sealable material having generally opposed edge portions; providing a layer of substantially transparent material including generally opposed edge portions; folding the opposed edge portions of the sealed bag over the opposed edge portions of the layer of substantially transparent material and heat sealing the folded edge portions to the sealed bag through the holes.
1. A pressure infusion device, comprising:
a sealed bag of flexible, heat-sealable material including generally opposed edge portions, said sealed bag defining an interior, wherein said opposed edge portions define a portion of said sealed bag defining said interior;
means for pressurizing said interior of said sealed bag;
a pressure gauge in fluid communication with said interior of said sealed bag;
a layer of substantially transparent material including generally opposed edge portions, each edge portion of said layer provided with a plurality of holes;
said opposed edge portions of said sealed bag folded over said opposed edge portions of said layer of substantially transparent material, wherein said edge portions of said layer of substantially transparent material are heat sealed to said edge portions of said sealed bag through said holes such that said holes overlay said edge portions of said bag defining said interior, said layer of substantially transparent material thereby mounted to said sealed bag such that a space is provided between said sealed bag and said layer of substantially transparent material for receiving a flexible, indicia bearing bag containing infusible liquid; and
said layer of substantially transparent material permitting said indicia to be seen and scanned therethrough.
2. The pressure infusion device according to claim 1 , wherein said layer of substantially transparent material includes an upper portion provided with a mounting hole, wherein the mounting hole is configured to receive a generally U-shaped mounting member, the mounting member configured to removably mount said bag containing infusible liquid between said layer of substantially transparent material and said sealed bag.
3. The pressure infusion device according to claim 1 wherein said layer of substantially transparent material includes an upper edge portion provided with an integrally formed and outwardly extending tab portion provided with a hole for mounting said layer of substantially transparent material and thereby said pressure infusion device to an I.V. stand.
4. The pressure infusion device according to claim 1 wherein said sealed bag is comprised of opposed layers of heat-sealable material having opposed edge portions heat sealed together.
5. The pressure infusion device according to claim 4 wherein said opposed layers of heat-sealable material comprise opposed layers of urethane coated nylon.
6. The pressure infusion device according to claim 1 wherein said layer of substantially transparent material is a layer of substantially transparent vinyl film.
7. The pressure infusion device according to claim 1 wherein said layer of substantially transparent material is a layer of substantially transparent cast nylon.
8. The pressure infusion device according to claim 1 wherein said pressure gauge is mounted to said sealed bag and includes an internal portion residing interiorly of said sealed bag for exposure to the pressure in said sealed bag and an external portion residing exteriorly of said sealed bag.
9. The pressure infusion device according to claim 1 wherein said means for pressurizing the interior of said sealed bag includes a squeeze bulb and a length of tubing mounted to said squeeze bulb and said sealed bag and for placing said squeeze bulb in fluid communication with the interior of said sealed bag.
10. The pressure infusion device according to claim 1 wherein said plurality of holes are disposed in two spaced apart, generally parallel, straight rows of holes.
11. A pressure infusion device, comprising:
a sealed bag of flexible, heat-sealable material including generally opposed edge portions, said sealed bag defining an interior, wherein said opposed edge portions define a portion of said sealed bag defining said interior;
a layer of substantially transparent material including generally opposed edge portions, each edge portion of said layer provided with a plurality of holes;
said opposed edge portions of said sealed bag folded over said opposed edge portions of said layer of substantially transparent material, wherein said edge portions of said layer of substantially transparent material are heat sealed to said edge portions of said sealed bag through said holes such that said holes overlay said edge portions of said bag defining said interior, said layer of substantially transparent material thereby mounted to said sealed bag such that a space is provided between said sealed bag and said layer of substantially transparent material for receiving a flexible, indicia bearing bag containing infusible liquid, wherein said interior is configured to be pressurized by a pressure source; and
said layer of substantially transparent material permitting said indicia to be seen and scanned therethrough.
12. The pressure infusion device according to claim 11 wherein said plurality of holes are disposed in two spaced apart, substantially parallel straight rows of holes.
