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.

A swing training assembly includes a shuttle, a shuttle travel track, a tensioner, a shuttle displacement line and a shuttle pulley. The shuttle resides in the shuttle travel track and the shuttle pulley and shuttle displacement line are adapted to linearly displace the shuttle to different shuttle positions within the shuttle travel track in response to displacement forces applied to the shuttle pulley by a user pulling on the shuttle displacement line. The tensioner provides an opposing counter-force to control the rate of shuttle displacement. The swing training assembly may also include body positioning limits to maintain proper body alignment while the user pulls on the shuttle displacement line.

A hinge for an orthopedic brace has two rotation plates, a pivotal connector connecting the rotation plates, a rotation limiting mechanism, and a rotation locking mechanism. The rotation limiting mechanism includes a rotation limiting face formed in one of the rotation plates and a rotation limiting assembly which has a stop face engageable with the rotation limiting face upon rotation of the rotation plates in a given direction to limit further rotation in that direction. The rotation locking mechanism includes a series of lock notches formed in one of the rotation plates and a rotation lock pin positionable within one of the lock notches to lock the rotation plates in a fixed position.

A continuous passive motion device is provided having specific application to rehabilitative treatment of the elbow or shoulder. The device includes a motorized winch displacable in a first or second direction, a cord suspended from the winch by a variable extension length, which increases when the winch is displaced in the first direction and decreases when the winch is displaced in the second direction, and an arm harness associated with the cord. An arm of a patient is suspended from a suspension point on the cord and the motorized winch is activated to alternately displace the winch in the first and second directions, thereby providing a plurality of repetitive treatment cycles. Each treatment cycle moves the suspension point and correspondingly the elbow or shoulder from a lower treatment limit to an upper treatment limit and back to the lower treatment limit.

A knee brace is provided having upper and lower arms and a hinge assembly positionable about the knee to one side of the patella. The hinge assembly has a hinge pivot and a tension strap lever. The upper and lower arms and tension strap lever are each rotatable about the hinge pivot. A compression member is positioned in engagement with the knee on the opposite side of the patella from the hinge assembly and a tension strap engages the compression member and is connected to the tension strap lever. The tension strap applies a tension force to the compression member which increases when the upper and lower arms and tension strap lever rotationally transition from a flexion position to an extension position and decreases when the upper and lower arms and tension strap lever rotationally transition from the extension position to the flexion position.

A strap connector assembly for an orthopedic brace has a retention post, which has a post cross-sectional dimension, and a chamber, which has a retention aperture. The retention aperture is bounded at least in part by a flexible segment and has an aperture cross-sectional dimension less than the post cross-sectional dimension when the flexible segment is unstressed. However, the aperture cross-sectional dimension is substantially equal to the post cross-sectional dimension when the flexible segment is stressed by the retention post. The retention aperture, flexible segment and retention post cooperatively enable a user to selectively connect or disconnect a strap to or from the orthopedic brace while maintaining the adjustment of the strap.

An integrated infusion and aspiration system includes of a flow control system and a catheter assembly. The catheter assembly includes an infusion catheter and an aspiration catheter, each having ports located at the distal end of thereof. The distal ends of the catheters are separated so that the aspiration catheter ports can be positioned on an opposing side of a surgical wound site from the infusion catheter ports. Methods of operation of the integrated infusion and aspiration system provides for uninterrupted aspiration with concurrent controlled delivery of an infusion solution such that the infusion solution is substantially evenly dispersed of over the wound site.

A portable, patient-controlled medication delivery system includes an infusion pump and a catheter assembly. The infusion pump retains a treatment fluid and provides a drive mechanism for delivering the treatment fluid to a patient via the catheter assembly. The infusion pump includes a fluid reservoir, a dosage chamber, a displacement piston displacable within the dosage chamber, a charge flowpath providing fluid communication between the fluid reservoir and the dosage chamber, and a passive flow restrictor positioned in the charge flowpath. An elastic member is also positioned in the infusion pump to exert an elastic displacement force on the displacement piston, which expands the dosage chamber and draws the treatment fluid from the fluid reservoir into the dosage chamber at a charge flow rate controlled by the passive flow restrictor. When an opposing manual displacement force is exerted on the displacement piston, the dosage chamber contracts and discharges the treatment fluid from the dosage chamber to the treatment site.
