The disclosed air filtration system filters both entering and exiting air. A primary structural element of the air filtration system is the unitary helmet member, which fits over the user's head. The unitary helmet member includes both a front aperture near the user's forehead and a rear aperture near the upper rear portion of the user's head. The unitary helmet member is blow-molded and therefore simple in construction. An interior channel connects the front aperture to the rear aperture, and a fan located over the rear aperture circulates air between these two apertures. A hood filter and a face shield fit over the unitary helmet member. The hood filter filters air passing through the rear aperture, and further filters air passing through a rear portion of the hood filter. Only the single fan is needed to draw air into the hood filter and remove air from the hood filter. The fan is placed over the rear aperture, thus distributing weight on the upper rear portion of the user's head to reduce stress and fatigue of the user. A secondary filter for added performance may be placed under the hood filter or over the fan inlet surface. A middle aperture located on the unitary helmet member between the front and rear apertures provides for a venting function to allow warm air to pass to the top of the user's head before exiting through the hood filter.

A surgical gown is adapted to be operatively disposed to substantially cover a surgeon wearing a ventilator having a waist-mounted power unit, a head-mounted manifold structure, and at least one tube extending therebetween. The gown includes a head section, a waist section, and a shoulder section appropriately configured to cover analogous portions of the surgeon's body. A ventilator section, disposed between the head section and the waist section when the gown is operatively disposed on the surgeon, defines tube channel to receive the tube of the ventilator. This ventilator section forms an enlargement which facilitates movement of the head of the surgeon without substantial restriction by the head section of the gown. An interior tie gathers a front section of the gown around the neck of the surgeon to isolate movement between the head section and shoulder section. The front section of the gown is covered with a plastic laminate to render the gown impermeable to fluids emanating from the front of the surgeon.

A dipstick locator device is mounted inside the engine compartment of a motor vehicle, and more particularly to the dipstick assembly. The device includes a light source which is activated at least when the hood is lifted to enable a person to locate the dipstick even under poor lighting conditions.
