A dynamic splint is provided which applies a bias force across a body joint with a magnitude which is adjustable at a pivot in the splint. At the pivot, a joint enclosure is provided to house a coiled leaf spring having one end connected to a movable adjustment mechanism. The relative magnitude of the bias is indicated by an indicator bearing numeric markings which moves with movement of the adjustment mechanism. A pin look mechanism is provided for locking pivoted strut members of the splint to prevent relative movement thereof about the pivot.

Dynamic splint

A dynamic splint provides a bias force with magnitude adjustable by a mechanism located at a pivotal joint. Specific embodiments include a dynamic ankle splint incorporating a correction cradle. The correction cradle applies a torsional force to the foot, thus permitting correction of inversion and eversion of the foot in conjunction with correction of dorsiflexion and plantar flexion. In another embodiment, a dynamic wrist splint attaches to the forearm and provides a novel palm interface which adjusts to apply force over a large area of the palm depending on the relative angular position of the hand. A flexion strap is provided at the back of the hand for applying flexion forces. Further aspects of the invention include visible display of the bias magnitude. The relative magnitude is indicated by numeric markings on a rotating member of the adjustment mechanism. The portion of the rotating member having the appropriate magnitude marking is visible through an aperture in the housing. Additionally, a pin lock mechanism is provided for locking the strut members to prevent relative movement thereof and to temporarily prevent the application of force by the bias unit during attachment and removal of the splint.

The instant invention is directed to a mammary prosthesis injector. The injector comprises a hollow tube having an opening at one end thereof. A bag for holding the prosthesis and reducing friction between the tube and the prosthesis is located, in part, within the tube. A mechanism for pulling the bag from within the tube is slidably mounted on the exterior of the tube and engages the bag. The prosthesis, which is held within the bag which is within the tube, is ejected from the tube and through the opening when the pulling mechanism is slid along the exterior of the tube.

An automatic reorder and alarm system for use with residential fuel-oil tanks which sends reorder and alarm data to a central station over the direct-dial telephone network when the fuel-oil level in the tank falls below a predetermined value or when an alarm situation, such as low temperature, occurs at the tank location. An inexpensive sensor/sending unit located at each customer tank includes a simple sensor which mounts on either the tank or an existing fuel-oil level gauge, a microcontroller circuit and a modem circuit. The microcontroller circuit uses a simple low-stability oscillator as a reference for internal operations and for modem transmission frequencies. Because the oscillator frequency cannot be precisely determined due to component tolerances and has a substantial amount of drift, a special data transmission format is used for data transmission over the telephone lines between the microcontroller and the central station. The data format consists of a selected pattern of mark and space signals in which each mark signal consists of a predetermined number of cycles of an oscillating signal whose frequency is determined by the internal modem oscillator and each space signal is an equivalent time period without a signal. At the receiver the bit time duration is determined by averaging bit times in a predetermined bit pattern header.
