Abstract: A small, inexpensive, but reliable pressure warning system includes a plurality of pressure sensors which are disposed between an orthopedic restraining member and an injured portion of a patient's body, and a processor and alarm unit coupled to the pressure sensor and providing a warning when the pressure reaches a danger level (i.e. 30 mm) in which medical assistance is required. If the pressure goes above a critical value (i.e. 35 mm), another warning is provided that immediate medical attention is needed. The processor and alarm unit can be mounted directly on the patient's cast and are disposable, one-use items.

Abstract: A device for mechanically supporting a patient's foot in such a manner that surgery can be performed on the tibia or ankle without the need for medical personnel to hold the leg. In addition, a fracture can be reduced, held, X-rayed and casted by the surgeon without help. The foot support device permits the reduction of tibial and ankle fractures slowly, thereby avoiding muscle spasm, and holds the reduced fracture in place for casting. The support device also substantially eliminates the problem of controlling a heavy leg during surgery or trauma treatment.

Abstract: An autoclavable device for mechanically holding a limb, particularly the leg, in the optimum position for performing surgery thereon. The device includes a central support member having an outwardly projecting rod for detachably securing the support member to an operating table. The device also includes an upwardly extending arm that is pivotally connected to the central support member and is adapted to engage the leg on one side or the other of the knee. An extension member in the form of an elongated rod is connected to the central support by means of a ball joint to permit angular adjustment of the rod with respect to the support. Adjustably mounted on the extension member rod is a U-shaped member adapted to engage the lower extremity of the leg in the area of the ankle. A handle is provided at the outer end of the extension member rod to facilitate adjusting the angular position of the rod and thus of the lower extremity of the leg.

Abstract: A hypodermic needle adapted to emit light from its distal end to facilitate venopuncture under subdued lighting conditions. The needle is used in conjunction with a portable light source, such as a battery handle and lamp, and includes a bundle of optical fibers that transmits light from the lamp to the distal end of the needle. A flexible catheter is releasably mounted on the needle and is adapted to be inserted in the vein after the needle has punctured same and thereafter the needle can be withdrawn from the catheter.

Abstract: A mixing tank and filtration system for operating room use. The tank is utilized for mixing a cement that is employed in reconstructing joints such as the hip joint, and mixing must take place in the operating room because the cement sets up in a very short time. The only presently approved cement gives off toxic fumes during the mixing which fumes frequently have a detrimental effect on the patient and operating room personnel. The mixing tank and filtration system disclosed herein are constructed and arranged to contain and draw off the toxic fumes whereby the detrimental effects on personnel are eliminated.
