Methods for wound protection and therapy
View Patent ↗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.
1. A method for treating a wound, comprising the steps of:
securing a housing to skin around a wound using an adhesive layer that sealingly encloses a perimeter of the housing, the housing defining a chamber;
delivering a therapeutic modality within the chamber to the wound; and
controlling the delivering of the therapeutic modality within the chamber to the wound using a programmable device; and
wherein the housing comprises:
a base enclosing a perimeter and being open at a first end and open at a second end;
a cushion having an open interior, the cushion secured circumferentially around the first end of the base to cushion the base upon securement of the housing around said wound by securement of the cushion to the skin using the adhesive layer, portions of the adhesive layer being interposed between the cushion and the skin, the cushion being an inflatable air cushion or a closed cell foam cushion; and
a lid attached about the second end of the base to be positionable between an open position and a closed position, with said housing secured about the wound, the chamber and wound are accessible when the lid is positioned in the open position, the chamber is fluid tight when the lid is positioned in the closed position.
2. The method of claim 1 , wherein the housing further comprises a port to communicate the therapeutic modality with the chamber.
3. The method of claim 1 , wherein the therapeutic modality is selected from the group consisting of proteolytic enzymes, lavages, nitric oxide, healing factors, immune modulators, moxibustion, controlled humidity, and controlled temperature.
4. The method of claim 1 , wherein the therapeutic modality comprises cyclical hyperbaric oxygen.
5. The method of claim 1 , wherein the therapeutic modality comprises cyclical suction.
6. The method of claim 5 , further comprising the step of:
communicating to the programmable device measurements from a sensor monitoring said housing.
7. The method of claim 1 , wherein the therapeutic modality includes delivering positive and negative pressures cyclically to the wound.
8. The method of claim 1 , wherein the lid is formed of transparent material for viewing of the chamber through the lid.
9. A method for treating a wound, comprising the steps of:
securing a housing to skin around a wound using an adhesive layer that sealingly encloses a perimeter of the housing, the housing defining a chamber; and
delivering a therapeutic modality within the chamber to the wound, the therapeutic modality comprising gas at a pressure that differs from ambient pressure, the gas directly contacting the wound;
the housing comprising:
a base enclosing a perimeter and being open at a first end and open at a second end;
a cushion having an open interior, the cushion secured around the first end of the base to cushion the base upon securement of the housing around said wound, the cushion being an inflatable air cushion or a closed cell foam cushion, and at least portions of the adhesive layers interposed between the cushion and the skin;
and
an openable lid attached about the second end of the base to form the chamber about the wound that is fluid tight when said housing is secured around the wound.
10. The method of claim 9 , wherein the hosing further comprises a port to communicate the therapeutic modality with the chamber.
11. The method of claim 9 , wherein the therapeutic modality includes delivering the gas cyclically at positive pressure greater than ambient pressure and at negative pressure less than ambient pressure within the chamber to the wound.
12. The method of claim 11 , wherein the gas within the chamber consists essentially of oxygen.
13. The method of claim 9 , wherein the therapeutic modality includes delivering cyclically pressures of nitric oxide within the chamber to the wound.
14. A method for treating a wound, comprising the steps of:
enclosing a wound within a chamber that is fluid-tight by securing a housing to skin around the wound using an adhesive layer that sealingly encloses a perimeter of the housing up the skin, the housing comprising an openable lid; and
delivering from a single source cyclical pressure changes of gas within the chamber to the wound, the cyclical pressure changes include positive pressure greater than ambient pressure followed by negative pressure less than ambient pressure.
15. The method of claim 14 , the gas within the chamber comprising air.
16. The method of claim 14 , the gas within the chamber consists essentially of pure oxygen.
17. The method of claim 14 , further comprising the steps of:
communicating pressure measurements from a sensor monitoring the chamber to a programmable device; and
controlling the delivering of the cyclical pressure changes within the chamber to the wound by the programmable device using the pressure measurements.
18. The method of claim 14 , wherein a cushion is secured around the housing to cushion the housing when the housing is in sealing securement about the wound, the cushion being an inflatable air cushion or a closed cell foam cushion.
19. The method of claim 14 , the housing being compression-resistant.
20. The method of claim 14 , further comprising the step of:
delivering a therapy selected from the group consisting of proteolytic enzymes, lavage, nitric oxide, healing factor, immune modulator, moxibustion, controlled humidity, and controlled temperature.
