A thermal blanket for flowing temperature controlled air upon a patient wherein the blanket is inflated with air and orifices within the blanket permit the air to flow upon the patient. The improvement includes the locating of the air inlet at a central blanket location in the patient's chest region to permit the highest air temperature to be available over the chest region, and the air flow direction produces optimum distribution. The locating of the air hose upon the blanket upper side permits the inflated blanket to insulate the hose from the patient, the portion of the blanket placed over the patient's head is perforated to facilitate forming a head receiving opening, and a transparent barrier may be affixed to the blanket upper side to cover the patient's face during respiration.

Upper body thermal blanket

A disposable pneumatic thermal blanket for controlling a patient's body temperature wherein the blanket includes structure for providing access through the blanket for surgical purposes. The inflatable blanket consists of upper and lower thermoplastic sheets heat sealed at the periphery and specified locations and sealed slits within the blanket central region permit access to a patient without loss of temperature controlled air. The blanket includes strategically placed adhesive strips or patches to aid the positioning of folded blanket access portions, or positioning of the blanket on the patient, and the location and relationship of the slits permit a variety of shapes and sizes of access openings to be selectively formed.

Thermal blanket with surgical access

A pneumatic, disposable, temperature control blanket pressurized with a heated or cooled air comprises an inflated envelope having a lower sheet having openings formed therein for impinging the air upon a patient. Air is introduced into the blanket envelope at a single inlet port, and an interior flexible conduit or subtube located within the envelope communicates with the inlet for distributing freshly introduced air throughout the blanket length with little temperature loss.

Thermal medical blanket using internal subtube

The invention pertains to the method and apparatus for forming air flow control orifices in a patient body temperature regulating blanket consisting of an inflated envelope defined by thin plastic film wherein temperature controlled air flows through the blanket orifices upon the patient's body. The blanket side disposed toward the patient is pierced by a sharp pointed punch having a plurality of intersecting facets defining sharpened intersecting edges. The punch apex and facet intersecting edges are related to the moving film in such a manner that the penetration of the punch forms a plurality of flexible valve flaps, and the valve flaps engaging the patient's body will be retained in a closed condition to restrain air flow through those orifices engaging the body to prevent exposure to excessive air temperatures.

Method of controlling air flow from an inflated blanket

The invention pertains to a fiber optic lamp system such as those employed in medical diagnostic systems using a cabinet containing a power supply having a front extendible drawer containing a 250 watt focused beam metal halide arc lamp mounted in a removable bracket which includes a sensing tab extension. The bracket sensing tab operates an electrical interlock switch when the proper lamp is properly installed. The interlock switch controls power to the system whose circuit includes pin and floating sleeve electrical connectors which automatically directly completes the circuit to the arc lamp upon the drawer being closed. The amount of light transferred to the fiber optic cable is optimized by offsetting the axis of focused light with respect to the optic cable axis at the cable interface.

A disposal pneumatic temperature controlled blanket consisting of flexible upper and lower sheets interconnected at their peripheries to define an inflatable envelope. The lower sheet outer surface is provided with a friction producing layer and a plurality of orifices are formed in the lower sheet and layer whereby temperature controlled pressurized air introduced into the envelope will be distributed through the orifices upon the patient's body to regulate patient body temperature. The envelope sheets are staked or tacked intermediate the peripheries to control inflation and distribute the air and the location of the tacks define primary and secondary air passages to quickly and uniformly distribute the air with a minimum of heat loss to various blanket locations so as to achieve substantially uniform patient body temperature exposure.

The punch apex and facet intersecting edges are related to the moving film in such a manner that the penetration of the punch forms a plurality of flexible valve flaps, and the valve flaps engaging the patient's body will be retained in a closed condition to restrain air flow through those orifices engaging the body to prevent exposure to excessive air temperatures.

A disposable patient heating or cooling blanket having three layers of flexible sheeting two of which form an air chamber, the third of which is a comfortable layer for contact with the patient and which, having a greater friction characteristic, aids in keeping the blanket in place on the patient. The patient is bathed in conditioned air through a multiplicity of orifices in the bottom layers of the blanket and the size and location of the orifices are such that sufficient pressure exists within the blanket to prevent crimping blockage and to insure a uniform flow of air through the orifices throughout the blanket area. Conditioned air is introduced horizontally through an external nozzle which is inserted into a low cost foldable fitting plate bonded to the blanket which permits the blanket to be concisely folded and packaged.

Recessed light fixture for recreational vehicle or the like

The invention relates to an improvement in light fixtures of the type having a base, a socket receiving a bulb, and a primary reflector defined on the base located in relatively close proximity to the bulb. The improvement consists of a secondary reflector located between the primary reflector and the bulb. The secondary reflector is closely spaced from the primary reflector defining an air gap therebetween. The secondary reflector provides dispersion of concentrated heat produced by the bulb to maintain the primary reflector at a lower temperature whereby the air gap reduces heat transfer between the reflectors, and the secondary reflector is formed of a reflective material to provide improved light reflectance qualities.

Recreational vehicle interior light fixture

A shipping container assembly formed of cut and scored fiber board having a rectangular shape including side walls, closeable end flaps forming the top and bottom of the container and a plurality of inner dividers dividing the interior of the container into at least two adjacent sub-compartments. At least one of the side walls is provided with an access door in alignment with one of the sub-compartments providing a separate access. One of the dividers includes a flat portion and a rectangular box portion being open on both ends defining a sub-compartment, whereby at least one of the open ends is in alignment with an access door.
