摘要:
A heat exchanger has a laminar fluid flow path receivable between the heating plates of a high flow rate infusion unit to which heat is conducted by contact with the heating plates. A bubble trap and a valve are integrated with the heat exchanger. The bubble trap collects air from the infusate exiting the laminar flow path, and includes an air vent in contact with the infusate that vents the air from the bubble trap. The valve shuts off the flow of infusate if air is detected in the bubble trap.

A treatment device having a first portion in a first plane, a treatment portion with a cover in a second plane that defines a treatment volume extending between the first and second planes, and a flexible transition portion that connects the first portion to the treatment portion. The treatment portion including a polymeric foam ring having interior and exterior walls extending from the first plane to the second plane. The cover spanning the interior wall thereby forming a closed treatment volume. The polymeric foam ring may be impregnated with a medicament selected from the group including an antibiotic material, an antifungal material, an antimicrobrial material, a deodorant material and nitric oxide. The cover may include a pocket for use with an accessory, such as a heater or mapping grid.A method of treating a treatment area on a patient's skin with the treatment device. The treatment device includes a closed treatment volume having polymeric foam ring impregnated with a medicament. The treatment device is attached to the patient's skin, such that the closed treatment volume encloses the treatment area. The medicament is released into the treatment volume to bring the medicament into contact with the treatment area. Additional steps may include inserting a heater into the pocket or inserting the mapping grid into the pocket and tracking the treatment area with the mapping grid.

A tissue treatment apparatus is provided which includes a thermally conductive bandage, a heater in thermal contact with the bandage over a tissue treatment area, a heat spreading means acting between the heater and the bandage for laterally spreading heat transferred from the heater to the bandage in order that heat be substantially uniformly distributed across the bandage.

A bandage for autolytic debridement includes a fluid-impermeable enclosure having a sidewall forming a margin defining an opening, and a skin-facing surface that surrounds the opening. An attachment means is disposed on the skin-facing to attach the enclosure to the skin, with the margin extending outside of and surrounding at least the bed of a wound. When the enclosure is attached to the skin it creates a closed, fluid-impermeable chamber over a wound, substantially without contacting the wound. The bandage includes a fluid absorbent material disposed in the fluid-impermeable enclosure at or near the continuous margin, and out of the opening. The fluid absorbent material is thus positioned to receive and retain exudated fluid that originates in the wound, thereby by promoting autolytic debridement. The closed, fluid-impermeable chamber maintains a near-100% humid atmosphere about the wound, thereby promoting healing of the wound. The humid atmosphere and the structure of the bandage tend to maintain the temperature of the atmosphere about the wound at or near a normothermic level in the range of about 36° C. to about 38° C., thereby maintaining physiologic processes that drive autolytic debridement and wound healing.

A treatment device having an attachment portion the first plane, a treatment portion with a cover in a second plane that defines a treatment volume extending between the first and second plane, and a flexible transition portion that connects the attachment portion to the treatment portion. The transition portion attaches to the attachment portion by a first flexible connection and to the treatment portion by a second flexible connection, with a minimum inter-connecting distance being defined by a straight line between a first point on the first flexible connection and a second point, corresponding to the first point, on the second flexible connection. The transition portion's length exceeds the length of the straight line. A flexible, serrated standoff supports the wound cover. An absorptive foam ring that acts between the first plane on the cover has in it a medicament selected from the group including an antibiotic material, an antifungal material, and an antimicrobial material.

A non-contact wound treatment device suitable for releasable attachment to a patient's skin surface over a selected wound area in a non-contact position relative to the selected wound area, the wound treatment device comprising an attachment portion suitable for releasable attachment with the patient's skin surface, having an inner perimeter for defining the selected wound area, a wound treatment portion with a substantially planar wound cover and a support member supporting the wound cover, and a transition portion with a membrane connecting the wound treatment portion to the attachment portion, the membrane extending around the outer perimeter of the support member and attached to the attachment portion between the inner and outer perimeter of the attachment portion.
摘要:
A focal cooling apparatus includes a cooling, or heat sinking, layer over which a layer of compressible, thermally insulating material is disposed. The layer of compressible, thermally insulating material has a surface for supporting a portion of a human (or animal) body. The layer of compressible, thermally insulating material responds to pressure exerted against the surface by exhibiting a thermal resistance between the surface and the cooling layer that varies inversely with the pressure. Means are provided for maintaining the cooling layer at a predetermined temperature below normal human temperature.
