摘要:
A wound treatment system for applying suction to a wound, said system comprising a wound dressing having a wound contact structure, a conformable seal placed over the wound contact structure to seal the wound area, and a source of suction secured to the structure in order to apply pressure/suction to the wound.
摘要:
A composite structure, a suction-assisted wound treatment system including the composite structure and a method of making the same is disclosed. The composite structure includes a cover, a stiffener, and a releasable liner. The cover is a thin flexible film having an upper surface, an undersurface, a principal portion, a pair of marginal edges and an adhesive on the undersurface. The stiffener is releasably secured to the upper surface of the principal portion of the cover and includes a handle which is more rigid than the principal portion of the stiffener. The handle forms a portion of the undersurface of the stiffener and defines a finger space between it and portion of the cover disposed therebelow. The liner includes at least one section releasably secured to the adhesive of the cover. The stiffener and the handle are removable as a unit from the cover.

摘要:
A wound contact device comprising a permeable material and a wound contact layer having voids extending through the contact layer to. a depth in the permeable material. The wound contact layer can comprise a thin sheet or film forming a generally flat and smooth wound contact surface having essentially no discontinuities or gaps. The wound contact layer can comprise a thin sheet of highly calendered fabric forming a wound contact surface having a mean surface roughness in the range of about O microns to about 200 microns. In progressive wound healing, an embodiment of the wound contact device having the fabric contact surface is used in earlier healing stages and an embodiment of the wound contact device with film contact surface is used in later healing stages. The wound contact device is particularly useful in wound dressings for use in suction-assisted wound therapy.
摘要:
A pump system for applying negative pressure to a wound, including a flow monitor capable of detecting a deviation from a reference airflow rate provided by a controlled leak to determine whether the system is operating normally or abnormally, and a flow status annunciator to indicate a normal operating condition or whether an abnormal condition is a leak or an occluded line in the system. The pump system further includes a pressure controller for regulating operation of a pump to control pressure in the system at a range around a user-selected setpoint. The pump system may also include a waste collector and a level sensor for detecting when the collector is full.
摘要:
A portable suction pump for producing negative pressure in a system for applying suction to a wound, in which the pump has a pressure control circuit for controlling the operation of the pump to maintain the pressure between upper and lower limits around a pre-selected pressure, and a fault detection system to detect deviations in the level of negative pressure applied to the wound; wherein the fault detection system can operate independent of the pressure control circuit. In a preferred embodiment, the fault detection system uses deviation from a reference airflow to detect system faults.
