An adjustable vascular compression device assists in achieving partial or full occlusion of a blood vessel when applied to a patient's limb, for example, during or following a medical procedure. Pads on the device apply preferential compression to portions of the circumference of the limb so as to enable blood flow through adjacent blood vessels during the compression period. Further, rapid fastening, tightening, loosening and release is enabled by a single mechanism, and gradual adjustments to the tightness may be made without releasing said mechanism.

The multifunctional fish and lobster harvesting system is a device resembling a spear gun that uses an elastic band to propel a thrust shaft through a barrel toward a marine game animal. Either a spear point or a tri-barb gig can be coupled to the front end of the shaft and a lasso-snare is attached to the back end of the shaft. The shaft is propelled by the elastic band, with one end of the band attached to the handle and the other end attached to the back of the shaft. A user pulls the thrust shaft toward the back, stretching the band, and releases the shaft to propel the shaft toward a marine game animal. The shaft never leaves the barrel but stops via a travel limiter on the shaft. The device is able to be used with the back end facing forward to use the lasso-snare.

An improved ratchet or gear wrench that has a built-in, non-slip, gripping clip mechanism for retaining a nut in the tool, which can either be applied to the nut or clamped out-of-the-way. This tool allows a nut to be tightened or loosened from a bolt or threaded stud more quickly and with one hand. To attain this, the present invention essentially comprises a spring-loaded curveshaped gripping clip, mounted near the boxed-end of a ratchet wrench, which wraps around the opening of the wrench. The spring action of the gripping clip allows it to be easily pulled away from the opening of the wrench and clamped in an out-of-the-way position by means of a clamp or released into a functional gripping position by pushing downward on the clamp's release button. When released, the gripping clip presses against a nut, thereby creating pressure that secures the nut in the opening of the wrench. Optionally, a second gripping clip mechanism can be added on the opposite side of the wrench, positioned to apply force on the nut from the opposite direction, thereby providing non-slip nut retaining capability. In use, a mechanic or user will pull the spring-loaded gripping clip back away from the wrench's opening and snap it into the clamp, thereby storing potential energy in the spring. A nut is then placed in the wrench opening and the clamp's release button is pressed momentarily in a downward motion, releasing the gripping clip and allowing the spring to pull the gripping clip against the nut. The nut can be started on the bolt using only one hand and then quickly tightened without the wrench slipping off the nut. When removing a nut, the nut will remain retained in the tool until the user removes it, thereby preventing the nut from falling into an undesirable location that may make it difficult to find or reach.
