Abstract

A method and apparatus for protecting and treating wounds are provided. A housing is adapted to be adhesively secured over the wound of an injured or infected person. The housing has an opening for access to the wound, and is further provided with inlet and outlet ports for the application of therapeutic materials. There is particularly provided a program for a closed looped system for such wound care. Additionally, the invention provides for a protective and treating cover for the eye, which can be either opaque or translucent. Additionally, a mechanism for accurately depositing eye drops without risking injury to the eye is also provided.

Claims

1. A device for protecting and treating a wound, comprising:

a housing defining a chamber;

a lid integral to said housing and having an interlocking or hinge mechanism for opening and closing a first portion of said housing and movable between open and closed positions to allow ready access to said chamber;

a cushion secured about a perimeter of a second portion of said housing, said second portion being open and said cushion defining an annulus, said cushion being an inflatable air cushion or a closed cell foam cushion; and

an adhesive layer for securing said cushion and attached housing over the body of a patient, wherein said device is fluid tight.

2. The device as recited in claim 1, wherein said cushion is pliable, conformable and compressible.

3. The device as recited in claim 2, wherein said lid is tinted to exclude light and photostimulation.

4. The device as recited in claim 2, wherein said lid or housing includes a receptacle to receive a therapeutic modality.

5. The device as recited in claim 4, wherein said therapeutic modality is selected from the group of biotherapeutic agents, moist packs, dry packs, heating packs, cooling packs, a source of oxygen, a source of nitric oxide, and moxibustion.

6. The device as recited in claim 2, wherein said housing and lid define a chamber over a wound when said lid is closed, said device with said lid closed having at least one port for passage of a therapeutic modality into or out of the chamber.

7. The device as recited in claim 1, wherein said housing forms part of a system for optimally protecting and flexibly controlling the therapeutic environment over a wound, is sustainably anchored over the wound, and has delivered within its chamber whatever beneficial therapies needed, including but not limited to proteolytic enzymes, antimicrobial lavages, biotherapy, cyclical hyperbaric oxygen, cyclical controlled suction, nitric oxide, bioengineered healing factors and substrates, and controlled humidity and temperature.

8. The device as recited in claim 7, wherein an anchoring means comprises a layer of cyanoacrylate adhesive interposed between said cushion and the skin and covers an area sized to correspond substantially to a foot print of the housing, and said layer of cyanoacrylate serves to buffer and protect the normal skin peripheral to the wound from prolonged contact with certain therapeutics and skin sensitivities.

9. The device as recited in claim 7, wherein said housing is secured over the wound by a layer of cyanoacrylate adhesive between said housing and skin surface.

10. The device as recited in claim 9, wherein said layer of cyanoacrylate adhesive is maintained in an applicator and said adhesive is applied upon discharge of the cyanoacrylate.

11. The device as recited in claim 10, wherein said applicator comprises an ampoule containing therein said adhesive to be dispensed.

19. The device as recited in claim 1, wherein said housing serves as a chamber for topical treatment using nitric oxide to enhance vasodilation and blood flow to the wound area.

20. The device as recited in claim 19, wherein said housing serves as a chamber for topical treatment using nitric oxide under pressure, wherein the pressure drives the nitric oxide deeper into wound tissue of the patient.

12. A device for protecting and treating a wound of a patient, comprising:

a housing defining a chamber and contacting a skin surface of the patient surrounding a wound;

a lid integral to said housing for opening and closing a first portion of said housing and movable between open and closed positions to allow ready access to said chamber; and

a cushion secured about a perimeter of a second portion of said housing, said second portion being open and said cushion defining an annulus

wherein said housing forms part of a system for optimally protecting and flexibly controlling the therapeutic environment over a wound, is sustainably anchored over the wound, is secured over the wound by a cyanoacrylate adhesive between said cushion and the skin surface surrounding the wound and has delivered within its chamber whatever beneficial therapies needed, including but not limited to proteolytic enzymes, antimicrobial lavages, biotherapy, cyclical hyperbaric oxygen, cyclical controlled suction, nitric oxide, bioengineered healing factors and substrates, and controlled humidity and temperature, wherein said cyanoacrylate adhesive is maintained in an applicator and is applied upon discharge of the cyanoacrylate adhesive from the applicator, wherein said applicator comprises an ampoule containing said cyanoacrylate adhesive to be dispensed, and wherein said ampoule is maintained in an applicator cylinder having at least one sharp rib or spline extending diametrically inwardly toward said ampoule, said rib or spline facilitating breaking of the ampoule upon crushing of the cylinder.

13. The device as recited in claim 12, wherein said ampoule is maintained in the applicator cylinder having diametrically opposed relief grooves extending axially along an inner surface thereof, said grooves facilitating crushing of said cylinder.

14. A device for protecting and treating a wound of a patient, comprising:

a housing defining a chamber and contacting a skin surface of the patient surrounding a wound;

a lid integral to said housing for opening and closing a first portion of said housing and movable between open and closed positions to allow ready access to said chamber; and

a cushion secured about a perimeter of a second portion of said housing, said second portion being open and said cushion defining an annulus

wherein said housing forms part of a system for optimally protecting and flexibly controlling the therapeutic environment over a wound, is sustainably anchored over the wound, and has delivered within its chamber whatever beneficial therapies are needed, including but not limited to proteolytic enzymes, antimicrobial lavages, biotherapy, cyclical hyperbaric oxygen, cyclical controlled suction, nitric oxide, bioengineered healing factors and substrates, and controlled humidity and temperature, wherein delivery of therapeutics is via a programmable device, and wherein said programmable device has an evacuation cartridge for removal of one or more contents of said housing.

15. The devices as recited in claim 14 wherein said programmable device has a delivery cartridge for selective passage of at least one therapeutic to said housing.

16. The device as recited in claim 15, wherein said delivery cartridge couples with at least one therapeutic source for controlled passage between said housing and programmable device.

17. The device as recited in claim 14, wherein the evacuation cartridge includes means for selective collection of at least one sample for analysis.

18. A device for protecting and treating a wound of a patient, comprising:

a housing defining a chamber and contacting a skin surface of the patient surrounding a wound, and has at least one port for variable engagement with sensors, stopcocks and connector tubings and for the passage of therapeutics; and

a lid integral to said housing for opening and closing a first portion of said housing and movable between open and closed positions to allow ready access to said chamber; and

a cushion secured about a perimeter of a second portion of said housing, said second portion being open and said cushion defining an annulus

wherein said housing forms part of a system for optimally protecting and flexibly controlling the therapeutic environment over a wound, is sustainably anchored over the wound, and has delivered within its chamber whatever beneficial therapies are needed, including but not limited to proteolytic enzymes, antimicrobial lavages, biotherapy, cyclical hyperbaric oxygen, cyclical controlled suction, nitric oxide, bioengineered healing factors and substrates, and controlled humidity and temperature, wherein said sensors include monitoring and maintaining parameters selected from a group including pressure, temperature, time, humidity, and levels of hematogenous factors, enzyme, therapeutic agent, microbe, and other physiological measurements.
