A wound packing for use with suction is provided. The wound packing comprises a plurality of nonabsorbent synthetic polymeric fibers coupled together to form a nonabsorbent material suitable for placement in the wound of a mammal. A method for treating the wound in a mammal using the disclosed wound packing is also provided.

The present invention relates to a device and method to control suction in a patient environment. The device comprises a body portion having an interior chamber adapted for coupling to a source of the vacuum; a valve comprising a shaft rotatably coupled to the body portion; and an actuator coupled to the shaft of the valve. In operation the valve is rotatable between i) a first position in which the vacuum is provided to the interior chamber via the valve at a first predetermined level and ii) a second position in which the vacuum is interrupted to the interior chamber. The actuator is adapted to move between a first position and a second position which increases the vacuum in the interior chamber to a second predetermined level for clearing occluded suction lines in the patient circuit.

A gauge is provided, preferably for patient use, in which a piston moves linearly within a gauge body against the force of a spring. A diaphragm separates the sensing side of the piston from the clean or atmosphere side of the piston. The diaphragm rolls against the piston and the wall of the chamber during changes in pressure, and does not interfere with accuracy of the readings. Dampening is provided out of the patient fluid stream. The sight glass through which measurements are read produces an optical magnification. A baffle prevents entrained particles from the patient from entering the gauge in significant amounts. A surface-to-surface seat enables the gauge to be mounted as a saddle seat on a duct, regulator or the like.

Entrapment and collection systems and method of entrapping and collecting biologic material produced on a patient are disclosed. The systems include a collection bag which formed of a flexible sheet material having a hollow interior, a first mouth and a second mouth. The first mouth is openable to enable the biological structure to be disposed in the hollow interior and to enable a removal instrument, e.g., a morcellator, to be introduced therethrough to engage the biologic structure to effect a procedure on it. The second mouth enables a viewing instrument to be extended through it for visualizing the procedure and is closeable by a drawstring to entrap biologic material produced by the procedure after the removal instrument and viewing instrument have been removed, whereupon the collection bag may be withdrawn from the body of the patient.
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 0 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.

Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible sizing tube having a distal end portion including a plurality of apertures. The control valve enables suction to be applied to the patient's stomach via the apertures to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the sizing tube to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.
摘要:
A suction regulator for controlling a level of negative pressure in a system in which compensatory clean airflow is used to isolate a control device for regulating suction delivered to a patient is disclosed. The regulator comprises an inlet; an outlet; a controller for controlling the suction delivered to the inlet; and a barrier for isolating the controller from the inlet.
摘要:
A system for applying suction to a wound uses a reference airflow for monitoring system operation. A reference airflow (or “controlled leak”) to the suction source is provided when the system is in operation, such that deviation from the reference airflow can be monitored as an indication of a change in operation, such as a leak in the seal of the wound cover, a blockage of airflow from crimping of the suction conduit or overfill of the waste collector, or an inadvertent turn off or disconnect from the suction source.

The invention provides a vacuum tube attachment device for vacuum assisted wound dressings. The device is in the form of a patch that can be attached to the primary wound cover. The patch forms a substantially air-tight seal to the primary wound cover, and a vacuum tube is fixed to the patch such that the patch can be oriented on the wound cover to locate the tube near an opening in the cover to allow vacuum pressure to be communicated to the wound. The patch has an adhesive area around its perimeter for attaching the patch in a substantially air-tight seal to the wound cover at any convenient location on the cover. Several embodiments of the patch are described.
