Abstract: A safety vein syringe with retractable standard needle, including a syringe barrel, a plunger, an injection needle and a guiding mechanism formed between the needle holder and the plunger. By means of the guiding mechanism, the plunger can be only axially moved within the barrel without rotation and two needle pulling members can be easily aligned with each other and latched together. A commonly used standard needle holder is replaceably connected with a second needle holder, whereby a user can replace the injection needle with another type of injection needle as necessary. The first needle pulling member is formed on the needle holder or the plunger, having at least one rotatable click. The second needle pulling member is formed on the plunger or the needle holder, having a detent. When the piston of the plunger is pushed to the bottom, the detent is easily and firmly engaged and hooked with the click.

Abstract: A mechanic encoder having a single conductors ring is provided. The arrangement between the a first and a second conducting fingers and the conductors ring are specially arranged such that the sequential signal pairs can be accurately and precisely generated, i.e. the resolution is accordingly increased. The conductors ring is configured by a plurality of conducting plates which are aligned with the center of the encoding wheel or in an alternative, those conducting plates are offset from the center of the center of the encoding wheel. The conductors ring is configured with a plurality of conducting portions and insulating portions which are alternatively contacted with the conducting fingers. The encoding wheel is powered by a third conducting finger and a sequential signal pairs can be detected from the output of the first and second conducting fingers. The signal pairs can be further processed and recognized to determine the rotation of the encoding wheel.

Abstract: A female urinary incontinence device is provided for preventing uncontrolled flow of urine. The device is in the form of a hollow plastic tube having an open proximal end for insertion into the bladder and a control device at the distal for controlling the flow of urine. The proximal end has an extensible and retractable mushroom shaped plastic which maintains the device in the bladder.

Abstract: The present invention is a stent delivery catheter system for placing a stent within a stenosis in a vessel of a human body. The stent delivery catheter system utilizes a slideable sheath with a thin-walled distal portion that is situated coaxially over a stent that is placed onto a balloon located at the distal portion of a balloon angioplasty catheter. The distal end of a central portion of the sheath has an interior shoulder which is capable of exerting a distally directed push force on the balloon angioplasty catheter at a point that is just proximal to the stent. This push force is then transferred through the non-deployed stent to a gradually tapered, highly flexible, lubricity coated distal tip of the balloon angioplasty catheter.

Abstract: An improved draining structure of a light bulb holder includes an inclined plate provided in the inner space of the holder. The electrical wire pre-assembled with the conductive plate is directly inserted into the light bulb holder through a triangular opening defined by the inclined plate in one technological step. The structure provides for assembling of the light bulb holder in a single technological step and provides the draining effect at the same time.
