Patent number: 7762987Abstract: A safety syringe device with separable needle stem by turning back includes a syringe tube, a push rod, a needle seat, a needle stem and a needle cap. The needle stem is attached to a bushing which is fitted to a core bit thereby fixing the needle seat at its position. The syringe tube and the needle seat that is screw combined are further tightly settled by dexterous positioning means. After finishing syringe, the needle sheet along with the needle stem is withdrawn and hidden in the syringe tube, the push rod can be broken at its brittle neck portion by tapping it against a breaking fringe formed around the syringe tube thereby leaving the needle seat and needle stem inside the syringe tube. By doing so, the used needle stem will never emerge out accidentally to puncture people's skin. The used syringe tube, push rod, needle seat and stem can be thrown away altogether to avoid restoring for reuse.Type: GrantFiled: October 26, 2007Date of Patent: July 27, 2010Inventor: Wei-Shui Wu

Patent number: 7735550Abstract: A method of blocking a water out zone in a production well includes the steps of connecting a throttle unit to a dump bailer, wherein the throttle unit is internally defined a flowing space, which can be adjusted in size to thereby control a flow rate of cement for blocking the water out zone; loading the cement into the dump bailer; slowly lowering down the loaded dump bailer to the water out zone in the production well; opening an outlet of the dump bailer under control, so that the cement flows from the dump bailer into the throttle unit and is released at a flow rate preset by adjusting the size of the flowing space; allowing the released cement to load up in the water out zone and slowly permeate into a gravel layer in the production well before becoming cured to block the water out zone.Type: GrantFiled: August 3, 2007Date of Patent: June 15, 2010Assignee: CPC CorporationInventors: Chi San Sun, Chien I Wu, Chia Shui Wu, Lai Fuh Fan, Te Kun Huang, Chen Hui Fan

Patent number: 7694737Abstract: In a method of blocking a water-out zone in a gas well by dumping cement and injecting pressurizing gas, a gas is injected into a target well to push and press accumulated water in the well back into the formation surrounding the well, so that the well is water-free; meanwhile, a dump bailer is lowered to the water-out zone in the well using a wire line. When the dump bailer has reached the water-out zone, it is controlled to open a bottom opening thereof to release cement milk loaded therein. The released cement milk accumulates in the water-out zone and then slowly flows into a gravel layer between a screen pipe and a wall of the well. The gas injection continues until the cement milk is cured and hardened to achieve the object of blocking the water-out zone.Type: GrantFiled: November 14, 2007Date of Patent: April 13, 2010Assignee: CPC Corporation, TaiwanInventors: Chi-San Sun, Chien-I Wu, Chia-Shui Wu, Lai-Fuh Fan, Te-Kun Huang, Chen-Hui Fan

Publication number: 20070078404Abstract: A safety syringe whose needle can be pulled back, which comprise: an syringe, a rod, a needle seat and a needle sheath, wherein the needle seat is installed inside the container part of the syringe in resist status. After the medicine is injected, the holding part of the push rod will enter the base of the needle seat to make the wall of the base become a conical wall gradually, and then make the holding part and concave-buckle part of the rod connect with the linking part and positioning part of the base. After connection, the outer diameter size of the base is still a little smaller than the inner diameter size of the circular-convex part. Therefore, after using and pulling out the push rod, the needle seat will be departed from the container part and stored inside the syringe to avoid people being stung by the discard syringe.Type: ApplicationFiled: July 22, 2005Publication date: April 5, 2007Inventor: Wei-Shui Wu
