Abstract
A thermal bandage apparatus for simultaneously dressing and thermally treating a wounded bodily area includes a fluid absorbent member having a wound contacting surface for absorbing bodily fluids produced by an open wound and holding means adjacent and connected to the fluid absorbent member for holding a thermal medium against the fluid absorbent member such that heat is transferred between the thermal medium and the open wound by thermal conduction through the fluid absorbent member. There is also disclosed an arrangement for providing a continuous supply of heat or cold to a wound.
Claims15
A thermal bandage apparatus for simultaneously dressing and thermally treating a wounded bodily area, the thermal bandage comprising:
- a) a fluid absorbent member having a wound contacting surface for absorbing bodily fluids produced by an open wound;
- b) securing means integral to the bandage, for securing the bandage in contact with the wound, the securing means including first and second flexible portions connected to and extending on opposite sides of the fluid absorbent member, the first and second flexible portions having first and second adhesive portions respectively, the first and second adhesive portions facing in the same direction as the wound contacting surface such that the adhesive portions adhere to areas adjacent to and on opposite sides of the wound;
- c) a pocket adjacent and connected to the fluid absorbent member for holding a thermal medium against the fluid absorbent member such that heat is transferred between the thermal medium and the open wound by thermal conduction through the fluid absorbent member;
- and
- d) pocket accessing means including an opening for accessing the pocket to permit replacement of the thermal medium without requiring that the fluid absorbent member be removed from the wound.
An apparatus for treating a wound, the apparatus including:
- a) a fluid absorbent member having a wound contacting surface for absorbing bodily fluids produced by an open wound;
- b) securing means integral to the apparatus, for securing the bandage in contact with the wound, the securing means including first and second flexible portions connected to and extending on opposite sides of the fluid absorbent member, the first and second flexible portions having first and second adhesive portions respectively, the first and second adhesive portions facing in the same direction as the absorbent member such that the adhesive portions adhere to areas adjacent to and on opposite sides of the wound;
- c) a pocket adjacent and connected to the fluid absorbent member;
- d) pocket accessing means including an opening for accessing the pocket to permit access thereto when the fluid absorbent member is in contact with a wound;
- e) temperature gradient means in the pocket, for maintaining a temperature gradient through said fluid absorbent member, the temperature gradient means being held against the fluid absorbent member such that heat is transferred between the temperature gradient means and the open wound by thermal conduction through the fluid absorbent member, the temperature gradient means being operable to be replaced in the pocket without requiring that the fluid absorbent member be removed from the wound.
A thermal bandage apparatus for simultaneously dressing and thermally treating a wounded bodily area, the thermal bandage comprising:
- a) a fluid absorbent member having a wound contacting surface for absorbing bodily fluids produced by an open wound;
- b) first and second flexible members, at least one of which is connected to the fluid absorbent member, the first and second flexible members having respective perimeter portions joined together such that said first and second flexible members are parallel to each other and such that a pocket is formed between said first and second flexible members, said pocket being adjacent to the fluid absorbent member and being operable to hold a thermal medium against the fluid absorbent member such that heat is transferred between the thermal medium and said wounded bodily area through the fluid absorbent member;
- c) pocket accessing means including an opening in at least one of said first and second flexible members for accessing the pocket;
- and
- d) securing means on at least one of said first and second flexible members, for securing the bandage in contact with the wound, said securing means including first and second flexible portions extending on opposite sides of the fluid absorbent member, the first and second flexible portions having first and second adhesive portions respectively.
