A portable, patient-controlled medication delivery system includes an infusion pump, a catheter assembly and an extension tubing set. The infusion pump retains a treatment fluid and provides a drive mechanism for delivering the treatment fluid to a patient. The catheter assembly has a medicine catheter which penetrates directly into the treatment site of the patient and the extension tubing set has an extension tube which connects the medicine catheter and infusion pump. The infusion pump includes a fluid reservoir, a dosage chamber, and a displacement piston displacable within the dosage chamber. An elastic member is also positioned in the infusion pump to exert a displacement force on the displacement piston. The elastic member is alternately transitionable between a more stressed position and a less stressed position. The elastic member elastically displaces the displacement piston in a first direction to expand the dosage chamber and draw the treatment fluid from the fluid reservoir into the dosage chamber when the elastic member transitions from the more stressed position to the less stressed position. The displacement piston is manually displaced in a second direction to contract the dosage chamber and discharge the treatment fluid from the dosage chamber to the treatment site when the elastic member transitions from the less stressed position to the more stressed position.

A hinge is provided for an orthopedic brace having an adjustable range of rotation. The hinge includes an outer member and an inner member that are rotatably connected in parallel alignment to one another. The peripheral edge of the outer member has a plurality of rotation limiting notches formed therein and the peripheral edge of the inner member has a rotation limiting face formed therein that is selectively alignable with one of the rotation limiting notches. Each of the peripheral edges also has a locking notch formed therein that is selectively alignable with the other. A rotation limiting stop is provided at the peripheral edge of the inner and outer members that is selectively positionable in one of the rotation limiting notches to define an adjustable range of rotation during a rotation mode of hinge operation. Rotation of the inner member is limited when the rotation limiting face engages the rotation limiting stop positioned in the selected notch. Alternatively, the rotation limiting stop is selectively positionable in the locking notches to lock the hinge against rotation in a locked mode of hinge operation. The hinge also includes a stop retainer, which retains the rotation limiting stop in the selected rotation limiting notch or locking notch during a rotation or locking mode of hinge operation, respectively, and which enables repositioning of the rotation limiting stop in an alternately selected rotation limiting notch during an adjustment mode of operation.

A pad is provided for therapeutically treating bodily injuries or ailments by positioning the pad on an affected part of the body and circulating a nonambient temperature treatment fluid through the pad. The pad has a bladder that is a symmetrical planar member configured in sections conformable to the contours of the body, thereby facilitating heat exchange between the pad and the patient. Included are a relatively wide main section and extension section that are fluid-communicatively joined with one another at the axis of symmetry across a relatively narrow connective section. The extension section is oblong-shaped, having a longitudinal axis aligned substantially perpendicular to the axis of symmetry and substantially parallel to the forward and rearward edges of the planar member. To specifically resist occlusion from kinking in the region of fluid ports into and out of the planar member, a portion of the planar member proximal and adjacent to the inlet and outlet ports is constructed in a manner that renders it substantially less flexible than the remainder of the planar member by affixing a patch of stiffened material to the surface of the planar member in the region of the inlet and outlet ports.

A shutoff valve is provided having a body enclosing a chamber that defines a continuous fluid passageway. A plunger resides in the chamber and is slidably positionable between a closed position wherein the fluid passageway is occluded and an open position wherein the fluid passageway enables fluid flow therethrough. A sealing member is also positioned in the passageway, which circumscribes the plunger to effectuate a seal when the plunger is in the closed position. A spring is compressibly mounted in the fluid passageway against the plunger to bias the plunger in the closed position. The chamber is characterized by a series of fluid-communicating sections formed therein which cooperate with a plurality of stages integrally positioned on the plunger to define the manner in which the valve is assembled and operated.

A system utilizable by a patient engaged in strengthening, stretching or range of motion exercise therapy of the ankle which contains a number of interactive components combinable in any one of several different configurations to provide the patient with specific ankle exercise devices. One such device provides ankle dorsiflexion and inversion/eversion strengthening exercises performed by moving the patient's foot in various directions against the elastic resistance of an elastomeric tube while the device is anchored in a door jamb. Another device provides ankle dorsiflexion, plantarflexion and inversion/eversion strengthening by exerting the foot against resistance from the patient across a strap. Yet another device provides ankle supination/pronation, toe flexion/extension, and isometric eversion exercises by performing various movements with the toes or feet to deform a towel. The final device is for stretching and ankle range of motion exercises by placing the patient's foot on a platform and rocking the platform on curved runners in various directions.
摘要:
An arm position monitor is provided having a magnetically attractive object, a magnet-coupler connector and a magnet. The magnetically attractive object is adapted to connect to an arm of a user and the magnet is adapted to connect to the same arm or to the other arm via the magnet-coupler connector. When positioned adjacent to one another during a golf swing, the magnet and magnetically attractive object attach to one another. However, if the user's arm substantially deviates from an optimal arm position during the swing, the user applies a detachment force greater than the magnetic attraction force that detaches the magnet from the magnetically attractive object. The arm position monitor alerts the user when this occurs.

A device is provided that indicates to a user when the user has properly shifted a sufficient amount of his or her downward force to the trail foot and thereafter to the lead foot during the course of a golf swing, thereby effecting an optimal golf swing.
