Apparatus and method is provided for shaping bone, in which a cooling, lubricating and/or curative fluid is delivered by means of the shaping member, in order to cool or lubricate the shaping member where it contacts the bone and/or to provide a curative fluid to the shaped surface of the bone. Preferably, the cooling fluid is at least partially water, with or without a curative substance carried therein, with the liquid being delivered at the shaping end of the member, in a direction toward the shaped bone. The fluid may be provided through the interior of the shaping member to at least one relatively narrow opening located at the shaping end of the member, or may be provided by at least one exterior channel that runs along at least one wide side of the shaping member. Optionally, cooling liquid may also be delivered through the interior of the shaping member for discharge through at least one narrow side thereof. A porous medium that allows for controlled flow of lubricating fluid may also be provided on at least one wide side surface of the shaping member.

An apparatus is disclosed for treating blood, by having the blood enter a container, in which essentially insoluble fats (or lipids) are discriminately withdrawn out of the blood as the blood flows through or rises in the container, preferably by means of a wick that is in the container, as the level of blood in the container rises around the wick, such that essentially insoluble lipids on the upper surface of the rising blood are removed from the blood, leaving behind essentially aqueous components of the blood. Clots, bone chips and the like are also removed from the blood by means of a filter.

A diaphragm divides a chamber into two segments, the first of which includes an air input port and an outlet port formed by a tube which contacts the diaphragm. On the other side of the diaphragm, a variably adjustable spring actuated piston urges the diaphragm to closure against the outlet port. Incoming air pressure deflects the diaphragm away from the outlet port against the spring and air compression, to allow predetermined exhaust air flow. A valved opening behind the diaphragm provides safety against diaphragm tear and malfunction.

A medical device that seals a wound and facilitates wound drainage with suction is provided. In one exemplary embodiment, the device comprises a suction portion, having both an inlet valve and an outlet valve, for suctioning fluids from the wound, and a sealing portion for sealing the wound by engaging the skin adjacent the wound, the suction portion and sealing portion being integral with one another. A method for draining a wound comprises the steps of under-packing the wound with a packing material; sealing the wound; and applying suction to the wound to promote wound drainage and to promote intimate contact between the wound and the packing material.

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.

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.

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.

Pulmonary exerciser device is provided whereby in one embodiment respective inspiratory and expiratory stages are stacked, the former above the latter, in a generally vertical, elongated tubular chamber. The patient pulmonary system is coupled to an intermediate point, and respective balls are carried in the expiratory and inspiratory chambers. Patient inhalation raises the lower ball, and patient exhalation raises the upper ball. Indicia are provided for incentive motivation and measurement of inspiration flow rate. Inspiration only is provided in other devices with provision for measurement and recording. In other devices, expiratory exercise is provided, with or without inspiratory exercise.

A turbine is mounted in an annular cavity, and is provided peripherally with exhaled air, which is exhausted axially therefrom. A fixed stator has axially extending, chordally penetrating slots therein, and a calibrating ring adjustable for partial occlusion of the slots. The rotor within the stator rides on jeweled bearings, and comprises fiberglass sheets bonded to the shaft and extending outwardly therefrom. Turns of the rotor are coupled to a stopwatch-type accumulator mechanism by substantially colinear, bent interfering shafts which define a low friction low inertia universal joint. The stopwatch accumulator is readily detachable for sterilization of the turbine/housing portion.
